Loha (Iron): Types, Shodhana, Marana, Qualities, Dosage
Iron is not just taken as a dietary supplement in Ayurveda; it is also used in various forms, such as herbal preparations and minerals, to treat a range of conditions, including liver and spleen disorders, diabetes, abdominal colicky pain, and anemia. Loha or Iron is a metallic chemical element with the symbol Fe (Latin: Ferrum) and atomic number 26.
Fresh iron surfaces are lustrous and silvery- grey in color, but oxidize in air to from a red or down coating of ferric oxide or rust. Iorn is essencial to nearly all known orgaisms. In cells, iron is generally stored in the centre of metalloponents) can catalyse production of toxic free radicals. Iron deficiency can lead to deficiency anemia.
Its relative density is 7.7 , melting point is 1600 degree C.
Synonyms
Loha, Ayasa, Shastrala, Teekshnaka, Kaalaayasa, Aayasa.

Availability
It is available in many nations in variable quantities. In India , it available in abundancy in Bihar, Odisha, Bengal, Madhya Pradesh etc
Ores of Iron
Iron ores are rockes and minerals from which metallic Iron can be economically extracted. The ores are usually rich in Iron oxides and vary in color from dark grey, bright yellow, deep purple to rusty red. The Iron itself is usually found in the form of magnetite (Fe3O4), Hematite(Fe2O3), goethic (FeO(OH)), Limonite (FeO(OH).n (H2O)) or siderite (FeCO3)
Types of Loha
 1. Munda Loha – (cast Iron or Pig Iron)
 2. Teekshna Loha (Wrught Iron)
 3. Kanta Loha ( Magnetic Iron ore or Magnetite)
Munda Loha is of 3 types –
 1. Mrudu Munda
 2. Kunta Munda
 3. Kadara munda
 Teekshna (piercing) Loha is of 6 types
 1. Khara Teekshna (piercing)
 2. Saara teekshna
 3. Hrunnala Teekshna (piercing)
 4. Taravatta Teekshna (piercing)
 5. Vaajira Teekshna (piercing)

HP workstations cut down production costs
Computer giant HP has just released its souped up workstation that promises higher performance for the financial traders, digital animators and mechanical engineers who will use it.
The super computer, which has two intel processors, is used for real time trading updates and can run up to eight monitors at the same time, as well as simulate 3D images of models.
HP vice president research and development workstations Terry Pilsner said workstations could save businesses of all sizes huge amounts of money in the initial stages of production.
Workstations can be used to test the strength of medal, the capacity buildings have to move in the wind, the structural soundness of bridges by stimulating virtual conditions.
Mr Pilsner said cars would still be tested during the final stages of production but during the initial stages virtual testing could save millions. Companies such as Lucas Films, Weta Digital and Pixar were using workstations to create digital images and models before entering into the production phase.
He said animation had fundamentally changed through such technology as images created in 3D format could now be rotated on screen and shared between colleagues through HP's SkyRoom across the globe in real time.
"It can predict and design the future virtually. It can design and test buildings to be resistant to earthquakes and wind through stimulation. It reduces the time from idea to conception," Mr Pilsner said.
The workstations are suitable for small businesses and many businesses are investing in technology that can reduce capital expenditure.
Cars can be virtually driven into brick walls through this technology and then engineers can assess the damage and see what needs to be fixed before the model goes into its first production cycle.
Because of this technology, engineers can return to the drawing table, redraft the model all before they start assembling the actual model. The implications for business of all sizes in immense, he said.

The essence of ObjectDesign - allocating responsibility over a set of abstractions forming a SystemOfNames. If you're familiar with WritingEffectiveUseCases, you know that your software is responsible for serving its actors and protecting the interests of its stakeholders. Meanwhile you're contemplating a set of abstractions. Some of these may model your problem domain (a DomainModel). Others may result from applying patterns, such as PatternsOfEnterpriseApplicationArchitecture.
The task is to decompose and allocate your software's responsibilities over the set of abstractions you're contemplating. You make trade-offs in the process, balancing such forces such as clarity, flexibility, expediency, and atomicity. You adjust your decomposition; you select and discard candidate abstractions. The process goes on forever. It is object-oriented design.

Compares the receiver object (this) with the argument object (that) for equivalence.
Any implementation of this method should be an equivalence relation:
 - It is reflexive: for any instance x of type Any, x.equals(x) should return true.

This is a broad question so for simplicity I will use Seal of Fire and Naturalize.
Scenario 1: Common exchangecreating a baseline.
 - Player A uses Naturalize on Seal of Fire
 - Player B Sacrifices SoF in response. SoF is highest on the stack and goes off first.
 - This leaves Naturalize without a valid target.
Scenario 2: Complicated exchangeIs this legal?
 - Player B Sacrifices SoF.
 - In response Player A targets it with Naturalize.
 - SoF is on the stack and it's ability has not resolved. Player B (as above) sacrifices SoF in response to the Naturalize.
Can Seal of Fire be placed back on the stack by re-activating its ability, potentially with a new target?
share|improve this question
2 Answers 2
No, your second example is not possible using the game rules.
Player A cannot target SoF with Naturalize, because it is currently in the graveyard. If they wanted to target the SoF, they need to do so when they had priority. Player A cannot prevent the SoF from being sacrificed for its ability anyway, since the ability exists independently of the source that created it. Seal of Fire says, "Sacrifice Seal of Fire: Seal of Fire deals 2 damage to target creature or player." It is an activate ability whose [Cost] is "Sacrifice Seal of Fire." If Player B paid the cost to activate SoF, it would no longer be on the battlefield by the time the Active Player received priority.
112.3b Activated abilities have a cost and an effect. They are written as "[Cost]: [Effect.] [Activation instructions (if any).]" A player may activate such an ability whenever he or she has priority. Doing so puts it on the stack, where it remains until it's countered, it resolves, or it otherwise leaves the stack. See rule 602, "Activating Activated Abilities."
116.1. Unless a spell or ability is instructing a player to take an action, which player can take actions at any given time is determined by a system of priority. The player with priority may cast spells, activate abilities, and take special actions.
 - It is not possible to sacrifice a permanent twice. After you sacrifice a permanent, it is placed into its owner's graveyard.

I was under the impression that because the ability had not resolved, as it was interrupted by the naturalize, it was placed on the stack before the card reached the graveyard. – Stormchild Mar 3 '12 at 19:29
_USER_ You pay all costs at the time you activate an ability (i.e. put it on the stack). The actions you take as part of paying costs don't use the stack. – Alex P Mar 3 '12 at 20:14
To put Alex's comment another way, the card goes to the graveyard at the same time as the ability is first placed on the stack. There is no opportunity for you or your opponent to do anything between the ability being placed on the stack and the moving of the Seal to the graveyard. The casting of Naturalize happens well after both of those actions. – David Z Mar 4 '12 at 7:46
user1873 is right. Scenario 2 is not legal since the sacrificing is a cost. To try to it clarify further: If Seal of Fire instead did "T: Destroy ~this~ and deal 2 damage to target player" it would still deal 2 damage to the player if you destroyed it before the ability resolved.
112.7a Once activated or triggered, an ability exists on the stack independently of its source. Destruction or removal of the source after that time won't affect the ability. Note that some abilities cause a source to do something (for example, "Prodigal Sorcerer deals 1 damage to target creature or player") rather than the ability doing anything directly. In these cases, any activated or triggered ability that references information about the source because the effect needs to be divided checks that information when the ability is put onto the stack. Otherwise, it will check that information when it resolves. In both instances, if the source is no longer in the zone it's expected to be in at that time, its last known information is used. The source can still perform the action even though it no longer exists.
A common analogy is that of a soldier throwing a grenade at you. Shooting the soldier after he has thrown the grenade won't prevent the grenade from killing you
The only way you can stop it is either counter the ability (Stifle) or prevent it from fulfill other restrictions like destroying mountains for Valakut, the molten pinnacle's land limit.

An Ancient Industrial Secret
Through Moses, God commanded the Israelites to dye the tassels on the corners of their garments blue. The secret to making this blue dye appears to have been lost about 500 years after the birth of Christ.
The Hebrew description of the blue that the Israelites were to use on their garments refers to what we today call hyacinthine purple. Researchers searched for the original process for making the dye using clues from the Bible, the Talmud and ancient trade records. Ancient references to the dye go back at least 3,600 years. While the ancients knew how to make this dye, we moderns don't.
Once researchers identified the correct color, they began to search for its origin. The Talmud says that the dye must be made from the uncontaminated extract from a shellfish. Eventually scientists discovered a species of shellfish, the Murex, that produces the raw material for exactly the color described in the Bible. Their final challenge was to perfect the dyeing method, which one researcher called one of the great industrial secrets of the ancient world.
In our modern technological age, it's good to be reminded that we are not the only generation to develop sophisticated industrial secrets. This broader perspective helps us to understand claims that ancient man was not so primitive as some today might imagine.

Dogs are audacious optimists. They do every little thing with enthusiasm and verve—manners be damned. Drinking water is no exception, and anyone who has ever seen a dog lap from its water bowl on a hot summer day knows they are willing to loudly splash their way to hydration. But how does the water get from bowl to mouth?
In 2014, a team of researchers led by Virginia Tech's Sunny Jung used high-speed cameras to film dogs as they drank water from a bowl. They examined the slow-motion footage and were able to study the mechanics behind a thirsty dog's tongue.
As Discover magazine reported, "dogs curve their tongues backwards in a ladle-shape … When they rip their tongues out of the water, they cause a significant amount of acceleration—about five times that of gravity."
Because dogs don't have cheeks, they can't create suction. To compensate, their tongues slap the water and pull it toward their maw in the form of a liquid column. As this water is suspended in mid-air, they chomp down on it and swallow, repeating the process until they're satisfied.
This tactic is very much like the one performed by cats. Unsurprisingly, felines are slightly more graceful and fastidious in their drinking habits. A cat gently dips its tongue into a beverage and neatly pulls a thin column of liquid into its mouth. The result is silent and splash-free:
Silent and splash free? The world's benevolent union of thirsty dogs kindly inquires: Where's the fun in that?

Rêve D Reve D RD-003-35 Aluminum Knuckle Stopper for RD-001 ASL Front Knuckle (3.5mm diameter, 2pcs)
Beschikbaarheid: Op voorraad (1)
RWD drift cars generally use a knuckle stopper (steering stopper) to adjust the maximum turning angle, but when maximizing the turning angle, many people use M3 set screws.
Even with the M3 set screw, the function of the stopper works, but the surface of the screw will hinder the movement of the suspension at the maximum turning angle.
This is where the [Aluminum Knuckle Stopper] comes into play!
Unlike the M3 set screw, the surface has no irregularities, so it does not hinder the movement of the suspension even at the maximum turning angle.
Furthermore, since it is made of lightweight aluminum, it is also effective in reducing weight by replacing it with an iron set screw.
The lineup consists of a Φ3.0mm and Φ3.5mm diameter part.
In addition to Φ3.0mm which realizes the maximum steering angle, Φ3.5mm which is an option when you want to control the steering angle only slightly is prepared.
Φ3.5mm is effective when the commercially available Φ4.0mm has insufficient steering angle and Φ3.0mm has too much angle!
If you are currently using an M3 set screw as a stopper or want to increase the steering angle more than a φ4.0mm stopper, please try it.
Screw 4.5mm
Pedestal diameter 5.5mm
Length from base to tip 16mm
Hexagonal hole dimensions 1.5mm across flats
* Above dimensions are suitable for RD-001 ASL Front Knuckle.
* If you use for the other knuckles, please check the dimensions of the knuckle, wheel before purchasing

- Use the Piping Wizard within a Reviewer Form
- Easily identify long questions
- Easily identify questions that appear more than once in your site
- Easily identify questions that don't have a title


Japanese Snow Monkeys And Their Obsession To Hot Springs
Japanese Snow Monkeys And Their Obsession To Hot Springs
Japanese macaques, or more likely known as Japanese snow monkeys, are one of the most famous animals from Japan. They are called snow monkeys because they are living in snowy area of Nagano, far north part of the lands of Sakura.
The looks of the monkeys are distinctive, with brown to greyish fur and red to pink faces. Locally, they are called Nihonzaru, the combination of "Nihon" (Japan) and "Saru" (monkey). Indeed, the species is native to Japan, and very familiar to Japanese people.
They are known to be the only nonhuman primate species to be inhabiting such north and cold area. It means no other primates, except human, are found to be living more northern and in colder climate than them.
But those physical and geographical features are not the ones making this species famous all around the world. Those monkeys are known to have unique habits that will draw your interest to them. In this article, we will talk about those habits.
Hot Spring Addict
Japanese people believe that bathing in hot springs, especially natural hot springs, will bring you healthiness both for your body and your minds. Although these monkeys might have not heard about this information from us, but they are known to love doing it.
Not only one or two monkeys doing the activities, but most tot all of them are seen to do the activity in almost daily basis. Even bathing in the hot spring with the monkeys has been a tourist attraction in the area since the monkeys are friendly to human too.
Researchers first suspected that the reason why they do it was to warm themselves from the cold winter in Nagano. Indeed, in the northern part of Japan winter can be torturing and harsh, but apparently that's not the only answer.
To learn better about their behavior, a group of researchers from Kyoto University studied 12 female Nihonzarus and observed the behaviors of the monkeys in two different seasons. First is the birth season from April to June, and the winter season from October to December.
The researchers observed which monkeys are bathing in the hot springs most often and for how long, and the measured the amount of glucocorticoid hormone in their fecal. This hormone is related to the stress level of the individuals, and what they found was shocking.
Zen Mode
800px-Macaca_Fuscata,_also_known_as_Japanese_Snow_Monkeys (Wikimedia Commons)
The researchers found out that instead of just putting themselves in the hot spring for just getting warmer, the monkeys have another reason to do so. Bathing in the hot springs make them calmer and helps them avoid getting stress.
The group of researchers' observations showed that in the cold winter months, the monkeys visit the hot spring more often. Suffering from the cold winter was known to be stressful, and that's why those monkeys regulate their body temperature in the hot springs.
Another discovery of behavior that the researchers found was that higher ranking of monkeys spend more time in the hot springs. The reason is because those higher rankings are often involved in more conflicts, which may result in more stress.
Thus, not only to keep themselves warm in the cold area, but the monkeys are bathing in the hot spring to make themselves calm and Zen. So, they can survive the cold winter and face internal conflicts without getting mad and risk their mental and physical health.
This behavior is more or less similar to human being, anytime we are under the threat of getting stressed, we try to find a way to get rid of it. Whether by taking a nice and soothing bath, playing video games, or just go to sleep. The choice that the monkeys picked was the first one.
Behave Culturally
Snow_Monkeys,_Nagano,_Japan (Wikimedia Commons)
The monkeys are also considered as one of the smartest nonhuman primates in the world. Well, taking a nice bath in the host springs is not the only behavior of the monkeys should be noticed, because researchers found that their stress management was not the only advanced behavior they have.
Studying the monkeys' behavior toward hot springs was not the only research has been done to them. Before, many researchers have conducted behavioral tests to them and every single of the test always resulted in interesting discovery about the monkeys' intelligence.
About 50 years ago, a group of researchers tried to supply the foods for the monkeys by giving food handouts. Since then, accepting foods from human has been considered acceptable by the groups, considered humans as friends, and the monkeys have less time to do foraging.
It means they more spare time to do things other than foraging by just becoming friendly to human, and that's why they needed something to do in their spare time. So, what do they do in the spare time? Some of them are hot-tubbing like mentioned above, some are playing with stones, and some others are 'cooking' their foods.
Following Trends
800px-Macaca_Fuscata (Wikimedia Commons)
In 1979, Michael Huffman, a primatologist at the Primate Research Institute (PRI) at Kyoto University noticed a female monkey playing with stones. "I had never seen, or heard about, anything like it. It was like a child playing with building blocks," he said.
When he came back to the site four years later, he found out that this kind of behavior has been adapted and spread to other monkeys. "Half the group was playing with stones, banging them on nearby roofs and making a total racquet," said Huffman.
Thus, it seemed that the monkeys are also following trends, like human beings do. "It shows the intelligence of the primate to us. I couldn't understand why a behavior that seemed to have no adaptive significance—it didn't provide an edge for survival or reproduction—could spread through a group and be maintained in a society for so long," Huffman explained.
Not only that, the monkeys are also known to 'cook' and 'season' their foods. Earlier in 1953, a monkey named Imo discovered a method to improve the quality of the food it got by washing it. about 10 years after the discovery of the behavior by scientists, another researchers group found out that more than two-third of the group were washing their foods.
With the discovery of unique yet intelligence behaviors of the primate species, researchers concluded that Japanese macaques are one of the most intelligence nonhuman primate in the world. Do you agree with the scientists?

Is the Universe Pregnant?
The Edges of Science: Crossing the Boundary from Physics to Metaphysics by Richard Morris
Morris looks into of fringe sciences, like the origin of the universe, super-strings, wormholes, and sub-atomic particles.
One of the surprising concepts is the theory of "baby universes." Some physicists believe that universes reproduce by "budding," having a segment of itself break off from the whole. Conceivably, our area of the universe could break off from the rest and form its own "baby," in which the laws of physics could be altered or distorted.
That would make things lively during an election year.

 Sex in periods
Can women do sex in periods?
Sex in periods
Menstruation or periods is a natural process in all healthy women. But the concept of menstruation is surrounded by many taboos. There are some common taboos attached to menstruation, which are totally irrational. These social stigmas have their roots in ignorance.
Women usually feel isolated and helpless during their periods. There is a long list of issues and taboos associated with having periods; you will often hear girls talk about post-period blues. Even the word period itself is very offensive, and guess what? You can't even call them periods, they should be referred to as the menstruation cycle.
Why is period blood considered impure?
We all know that periods are supposed to be a natural phenomenon, and there's no need to be ashamed of them. But sadly, many still consider period blood impure and talk about it in a hushed tone!
Why? Because period blood is often seen as a symbol of procreation, or as something that could lead to pregnancy. Therefore, it's only "natural" to believe that it's impure.
We all know that periods are a natural process, but on the other hand, it's a topic that is still considered taboo in India. Periods are considered a sign of impurity, but how can we change people's mindset?
There is only one way to get rid of these misconceptions and taboos around periods, that is by educating people and making them understand how pure it is to shed blood during periods for a woman.
A sensitive question, but can a woman really have sex during her periods?
There is no harm in having sex during periods, so there is no reason why you should not have your share of fun. However, there are a few things that you need to keep in mind when you are having sex during periods.
What is the time frame for sex during periods?
Having sex on the first day of your period could be a turn off due to excess blood flow and mood swings. Also, if you have a history of haemorrhaging or are undergoing vaginal surgery, avoid having sex during your periods.
Other than these factors, there is no need to worry about anything else. Nothing should stop you from having sex even if you are on your periods but some rules and tips need to be followed if you wish to have safe and pleasurable sexual intercourse.
What are the benefits of having sex during periods?
There are a lot of advantages of having sex during periods:
Period sex can provide relief from menstrual cramps
Sex leads to orgasm and orgasm is a great way to get relief from menstrual cramps. Menstrual cramps occur when the uterus contracts to release its thin lining. So when a woman achieves orgasm, the uterus muscles contract and then release, this could bring some relief from cramps. Sex also triggers the release of happy hormones, called endorphins.
Having sex during periods can result in shorter periods
Period sex can make your periods shorter because when the uterus walls contract during orgasm, the uterine contents are flushed out. This results in shorter periods.
Having sex during periods can increase libido
Due to hormonal fluctuations, sex drive keeps changing throughout the menstrual cycle. For most women, libido increases during the ovulation period (which arrives 14-15 days before the period starts), while other women feel more excited during their period itself.
Periods act as a natural lubricant
A good lubricant can provide adequate lubrication to make the act easier to perform. During periods, blood can act as a natural lubricant. So you don't have to use any commercial products.
Period sex can relieve headache
A study has found that about half of women with headache issues during periods got relief after having sex. So if you are tired of period migraines, the best you can do is to have sex!
Can you get pregnant by having sex during periods?
While it is very unlikely to get pregnant during periods, there is a possibility. So, it is highly recommended to use protection during sex even when you are on your periods.
Women are most likely to get pregnant during the ovulation phase, which occurs 14 days before the onset of the period. But every woman's cycle is different and so, if a woman's menstrual cycle is shorter then the risk of getting pregnant during the period would be considerably high.
Things to keep in mind while having sex during periods
 - Avoid using a tampon during sex.
 - Ask your partner to wear a latex condom to safeguard against unwanted pregnancy and STIs.
 - Try out different sex positions to find which one is actually suitable for you and your partner.
 - Spread a dark-coloured cloth or towel on the bed to prevent your bed sheet and also, catch blood leaks, if any.
 - Keep a towel or cloth near the bed to clean up afterwards.
 - Take shower and look after your personal hygiene after having sex.
 - Last but not the least, be honest and open with your partner by telling them what would make you comfortable.
Take Away
To have or not to have sex during periods is a personal choice but one should always be sportive to try out different sexual activities for fun. Sometimes, due to mood swings, depression, stress, fear of losing virginity, etc reduces the urge to have sex during periods. So, talk with your partner if you are worried about anything.

Contested wills: Why legal disputes don't stop after death
It all goes back to a particularly gruesome episode of grave robbing.
In 1614, Englishman William Haynes caused widespread disgust when he was caught digging up corpses to steal the sheets in which they were wrapped, before re-burying the bodies.
The court had to decide who he had stolen from: the corpses, or the people who had carefully wrapped their loved ones. In the end, the court ruled that Haynes had robbed from the living, since corpses cannot own property.
In death, we have fewer rights than we might think.
After a 15-month review, the Victorian Law Reform Commission last month recommended the state government introduce laws giving people the right to leave binding instructions over the disposal of their body (that is, whether they are buried or cremated), what rituals should accompany their funeral, and how they would like to be memorialised.
The commission was overwhelmed with submissions from people who told how their family had been riven by disputes after the death of a loved one.
One, who wished to remain anonymous, told of how their father remains buried in an unmarked grave, years after the man died.
They had remained close to the old man, visiting him often on his sickbed. But another of his children, a son from whom he had been estranged, took charge on the morning the father died; signing off on the paperwork at the funeral home and organising for the older man to be buried.
That son is yet to agree to the father's grave site having a plaque, a viewpoint causing deep distress to other family members.
Victorian Law Reform Commission chairman Philip Cummins says most people don't realise they have no say over what happens to their body after their death, even if they have made their wishes explicit before they die.
Instead, the right to decide what happens to a person's body rests with their executor, if they have a will, or administrator if they do not. This means it could fall to an accountant or lawyer to decide whether to honour a client's desire to be cremated and scattered at sea.
"People may reasonably expect funeral and burial arrangements to reflect their personal values and choices," Mr Cummins says.
"At the same time, if there is more clarity around people's wishes for their funeral, it will reduce the number of family disputes that occur after a person's death."
Tasmanian man Ben Jago knows first-hand the grief that can come from these fights.
In January 2015, he found the body of his long-term partner, Nathan Lunson, who had died by suicide after a long battle with mental illness. The pair had spent five years building a life together. They owned a house, shared a bank account, had filed joint tax returns and had been engaged for a year. They planned to marry in New Zealand.
But Ben says that when Nathan died, it was as if he had never existed. He says Nathan's mother took over the funeral arrangements and he was locked out of the process – further compounding his heartbreak.
Ben says Nathan wanted to be cremated in Hobart; he was instead buried in his home town, near his family. He and Ben's relationship was not so much as mentioned during the service.
Mr Jago puts this down to two factors: Nathan not having a will, and the pair not having registered their relationship, or married.
"If we'd been considered equal under the law, then absolutely things would have been different," Mr Jago says. "I actually didn't grieve for a long time. I don't know if I properly have yet. I'm still fighting."
For most people involved in end-of-life legal disputes, though, the tussle will centre on who stands to benefit from the dead person's will.
Partly, this is due to the rapid increases in life expectancy. A century ago, many people could be assured that the money they received from a parent's estate would go at least some of the way to help them set up a family home of their own. But Australians now live an average 25 years longer than they did then.
Kathy Wilson is the Law Institute of Victoria's head of succession planning, and Principal at law firm Aitken Partners.
She says disputes over wills generally take one of two forms. The first is challenges to the validity of a will, where a family member might claim the person who died did not have the mental capacity to make their will, understand what they were doing, or were forced to do so. They might even claim a will had been forged.
The second type of challenge, which is more common, is to the content of the will itself, where one person will challenge the amount of money or property they were bequeathed.
Ms Wilson says that as people live longer, and society shifts, the number of challenges to wills is increasing.
"There's no doubt about that, because society now recognises less formal sorts of relationships, like domestic relationships," she says.
In 1998, the Victorian government changed the law to allow more people to challenge wills, so long as they could show the person who died had been obliged to provide for them, and they had a corresponding need to be looked after.
But just four years later, the Victorian Law Reform Commission launched an inquiry into succession laws, amid fears the laws had become too liberal.
Lawyers cited the cases of neighbours, carers – and, in one case, an interstate house-sitter – being able to join a host of long-lost relatives to legally challenge for a share of an estate.
From January 1, 2015, Victorian law again imposed a limit on who can legally qualify as an "eligible person" to challenge wills, including children and step-children, former (with conditions) and current spouses and domestic partners, carers and grandchildren.
Ms Wilson says there is strong anecdotal evidence showing the number of challenges to the contents of wills is falling since these limits were reimposed.
More and more people are recording video wills, although Ms Wilson advises against this. Video testimonies raise eyebrows among succession planners: they can be more easily edited than can written testimonies.
Lawyers will be quick to tell you that a formal will, witnessed by two people aged over 18 is the most effective way to ensure your wishes are followed. But, says Wilson, "it can be on a paper napkin" – so long as the deceased person had intended that document to be their final will.
In the end, she says: "Sometimes you can meet with people and find out it's not about the money... it's about their place in the deceased person's life. Sometimes it's about control. Sometimes it's about religious and cultural beliefs."

Writing a will
 - Discuss your plans with your family
 - Make your wishes known
 - Write them down, in front of two witnesses who aren't executors or beneficiaries
 - Think about who you should provide for
 - Talk to a lawyer, and
 - Take their advice

The Glencoe Golf & Country Club (GGCC) is situated on the south bank of the Elbow River, approximately 12 km upstream of the Glenmore Dam. A significant portion of the GGCC is located within the floodway of the river. In June of 2013, the golf course was heavily damaged by overland flooding from the Elbow River.
As part of GGCC's flood mitigation strategy, Associated Engineering (AE) was retained to develop a detailed model of Elbow River to determine flooding impacts to the golf course during various river levels and to analyze the impacts of a raised barrier on the course and adjacent lands.
- Developing a 2-dimensional model of the Elbow River using Mike21.
- Modelling the impacts on the site from the 1:2, 5, 10, 25, 50, 100, 150, and 500-year flood events.
- Modelling the impacts of the flood events on the site and surrounding sites with a proposed flood protection barrier on the GGCC. The model will be used to support proposed flood protection for the GGCC by verifying impacts to adjacent lands of installing a flood protection barrier.

At Marriage Helper, we often hear from couples that they'd love to put their marriage back together, but their spouse did something terrible. It might be that they had an affair, gambled away their money, or had an addiction problem, but that act is now causing them to feel shame. That shame could be keeping them from feeling like their spouse can forgive them. It keeps them from doing the necessary things to put their marriage back together. Is there hope in this type of situation if you're wondering, "How can I help my spouse work through shame?"
Understanding Guilt And Shame
Luckily, the answer is yes. The feeling of guilt can be a good thing. When you feel guilt, it tells you something is wrong and you need to fix it. On the other hand, people who feel no guilt are labeled as psychopaths or sociopaths. But while short-term guilt can remind us we need to fix whatever is wrong, long-term guilt can cause a sense of shame if it's not dealt with properly.
Shame can take a toll on your psyche, sense of self-worth, self-confidence, and self-esteem. It leads you to believe negative things about yourself, which can even affect you physiologically. For example, you can start to feel like no one loves you and you're worthless when the guilt turns into shame. These feelings of shame can lead to an increase in depression, anxiety, and less immune function. Guilt is, "I did a bad thing." Shame is, "I am a bad thing."
In psychology, there's a lot of good work being done by people like Brené Brown researching shame and vulnerability. She's studying how vulnerability can be something that helps people reverse that shame by sharing the things causing them to feel shame. Finding acceptance on the other side can help people escape a constant shame cycle.
Shame Can Manifest In Many Ways
People who feel shame often won't be very transparent about why they are feeling shame. They feel like if you knew everything, then you would see them as a bad person as they see themselves. That makes them feel like they can't put their marriage back together because they don't feel you can forgive them. This thinking can lead to self-punishment.
The feelings of shame can manifest in many different ways. Besides causing them to feel like a bad person, it can lead to them becoming filled with pride. This can happen because they don't want to feel the shame; they want to try and cover it up. Covering it up can present itself as being confident or very sure of themselves.
So, what can you do if you are dealing with shame?
Understanding Your Shame
The first thing you can do is allow yourself to become vulnerable and do some self-reflection. Try to understand why you feel the shame. Some people will find their shame tied to something they did in their marriage, like having an affair. Even for people who have done something recently in their marriage, those feelings of shame may be at least partly tied to something that happened earlier in their life. Shame is such a deep feeling that it can take a long time to present itself.
These feelings of shame can have a wide range of causes. It might be that you were expected to be perfect during your childhood. You feel like you're not meeting that expectation now, making you unlovable. It might be the opposite end of the spectrum where you were constantly told you were a failure, leading you to believe it. Believing you're worthless is a self-fulfilling prophecy.
What Can Your Spouse Do To Help?
You can't change your feelings until you recognize that you're feeling shame, but your spouse can still help. If you already have a negative self-view, your spouse must be careful about how they respond to you. You can't continue to pile on shame by blaming them. The person experiencing shame needs you to be a safe place for them. Continuing to blame them for things will drive them to disconnect further. The path to coming out of shame is making them feel accepted despite what they have done or even the false beliefs they have about themselves.
Typically, that's not going to be accomplished by telling them they're worthy and valuable because their self-image is already negative. You need to be extremely honest about how you feel about what they did to cause the shame. That might sound contradictory, but if you instantly forgive your spouse and try to move on, they don't fully get to process what's happened. If your spouse is telling you how bad they are, they want you to listen and empathize with them instead of trying to fix them. They need to be able to release those feelings.
Overcoming their feelings of shame won't be a quick process; it can take anywhere from months to years. You should see some progress within the first few months, though. You need to continue having consistent conversations and reaffirming your love for them. You'll not want to discuss it daily because those feelings might be too much, but make sure it's consistent and as often as your spouse feels comfortable.
Using SMART Contact
Patience will be critical in this process. We've talked about the concept of SMART contact in several articles before. Simply put, SMART Communication teaches you the best way to approach any type of communication with your spouse in a "smart" way. Using these techniques in this situation will help by reminding you to avoid PUSH behaviors, respond in a kind, strong, and gentle way, and take it one day at a time.
Our intensive three-day workshops also discuss attachment theory which can be relevant to people experiencing shame. For example, your spouse might decide they don't want to have contact with anyone, even other family members. This is called dismissing avoidance, and we devote an entire section to these issues at the workshop.
Remember that guilt is good in the short-term, but long-term guilt can lead to negative thoughts about yourself. The best way to help your spouse through this is to be a listening ear and a consistent source of empathy for them. Try to emphasize the good that you see in your spouse. And finally, remember that you can't logic shame out of a person; you must love it out of them patiently.

What are Hospital Ice Chips?
Table of Contents
For oral hydration, hospitals use small pieces of Ice chips to soothe a sore throat or to cool the mouth and throat. Methods to make hospital ice chips are crushing ice cubes or breaking up the block of ice. Ice chips are typically made from purified water and are safe to consume. When patients cannot drink more significant amounts of liquid because of illness or medical treatment, they are commonly used in hospitals and other healthcare settings to help patients keep hydrated and comfortable. Some people also use ice chips at home to help with dehydration, sore throat, or other conditions that affect the mouth and throat.
Benefits Of Ice Chips
- Hydration: Ice chips can help to hydrate the body because is solid form of water. People who have trouble swallowing or might feel sick and struggle to drink more significant amounts of water will find this to be especially helpful.
- Cooling effect: Ice chips can provide a cooling effect on the body, which can help reduce fever or overheating.
- Sore throat relief: Ice chips can help numb the throat and temporarily relieve soreness or irritation.
- Oral hygiene: Ice chips can help to clean the mouth and teeth, as the cold temperature helps to make it bacteria free and freshen your breath.
- Digestive aid: Ice chips can help digestion, stimulate the small intestine, and reduce bloating or discomfort.
- Pain relief: To numb, use ice chips and reduce pain in some body regions, such as following a dental procedure or during a sports injury.
- Weight loss: Some people use ice chips to curb hunger cravings and assist with weight loss efforts.
- Energy boost: Ice chips can provide a quick burst of energy, as the body uses energy to heat the ice and bring it to body temperature.
Why Hospitals Give Ice Chips
Hospitals give ice chips for several reasons:
- Hydration: Ice chips can help keep a patient hydrated, especially if they cannot drink more significant amounts of fluids due to illness or surgery.
- Comfort: Ice chips can comfort patients who may have a dry mouth or throat due to medications or treatments.
- Oral care: After surgery, a patient might not be able to brush their teeth or wash their mouth with water. Ice chips can help to clean the mouth and teeth.
- Cooling: Ice chips can help to cool down a patient's body temperature in the hospital.
- Swelling: Ice chips can help to reduce swelling in the mouth, throat, or other areas of the body.
Ice chips are a simple but effective way to help care for patients in a hospital setting.
Why to Have Ice Chips only Before Surgery?
You can only have ice chips before surgery because they are easy to digest and do not need chewing or digestion. It is crucial because, during surgery, the body's digestive system is essentially shut down, so anything eaten before surgery will sit in the stomach and intestines without being properly processed. It can lead to nausea, vomiting, and other digestive issues. On the other hand, ice chips can be quickly and easily absorbed by the body and do not pose any potential digestive problems. Additionally, ice chips can help to keep you hydrated and can provide some relief for dry mouth or throat.
What Kind Of Ice Maker Do Hospitals Use?
Hospitals typically use commercial ice makers, which are larger and more powerful than residential ice makers. These ice makers can produce large quantities of ice, making them ideal for busy hospitals where ice is use for various purposes such as patient care, food and beverage service, and laboratory research. Some hospitals may also use ice makers specifically designed for medical use, equipped with features such as built-in water filtration systems to ensure the ice is clean and safe to consume.
In conclusion, hospital staff gives their patients ice chips since it simply keeps them hydrated before and following surgery. It makes sense to provide commercial ice rather than manually crushed ice to your patients, visitors, or staff members so they can enjoy their fizzy water or drinks while staying chilly or cool on a warm day. I suggest visiting my webpage if you want to enjoy ice chips in the convenience of your own house.


Ceiling Cables
Here's How You Can Hide Wires in an Exposed Ceiling
You're thinking of building a house with an exposed ceiling or maybe you already live in one. Either way, you realized the wires on the ceiling aren't exactly pretty or safe to look at. So, you're trying to learn how to hide the wires in your exposed ceiling.
To hide wires in an exposed ceiling, you'll need creativity. You'll also need some knowledge of safety concealing the wires to ensure it won't eventually cause any accidents. One way to hide wires in an exposed ceiling is by pinning them in place and painting them the same color as your ceiling.
This article will talk about how you can hide wires in an exposed ceiling. It will also discuss the trend of exposed ceilings and the types of exposed ceilings.
Hiding Wires in an Exposed Ceiling
Exposed ceilings give your house a rustic look when done right, and it also saves you some money. Without needing to spend on materials and labor to cover your ceiling, you can use that money to hide the wires instead and buy other things to enhance your house.
However, you need to keep in mind that your wires need to follow safety precautions to ensure they won't cause any accidents even when hidden. This means your wires should not be bare or open. They also need to rest in places that won't get wet or constant exposure to the elements. If they receive constant elemental exposure, they will easily wear out, and you will need to replace them.
To hide wires in an exposed ceiling, the first thing you need to do is ensure that they are attached to the beams. You can do this by using electrical staples like Gardner Bender metal staples on Amazon. Once all the wires are secured, you can start to creatively hide them by painting them or using cord covers, wooden mounds, or decorative boxes.
You Can Paint the Wires on the Ceiling
If you're bothered by your ceiling wires poking out in an exposed ceiling, one option is to paint the wires. This boosts your house's aesthetics without consuming too much money or time. To do this, all you need to do is buy paint that matches your ceiling beam's color. This camouflages your wires and keeps a simple ceiling.
You may also paint the ceiling beams themselves if you can't find the shade that matches the beams. You can find paint in your local hardware store or on Amazon. An excellent paint find is Majic Paints, which can coat many surfaces. You'll notice that most people opt for a white painted ceiling or wooden-colored wires, but you may pick other colors from Majic Paints.
The advantage of painting your ceiling wires or even ceiling beams is that you can choose a uniform color for your ceiling or design it. However, some disadvantages include paint expense and labor fees if you hire someone to do it. There's also a chance that you won't like the outcome.
You Can Use Cord Covers for the Ceiling Wires
If you don't want to paint but still want an easy fix for your exposed ceiling wires, check out some cord covers. You can easily find them on Amazon, and among the general public's favorites are Cord Cover Raceway Kit, Paintable Cord Concealer, and Cordinate Fabric Cord Cover.
Cord Cover Raceway and Paintable Cord Concealer both come as white sets of cord covers. You can paint them however you want to match your decor, or you can keep them that way for an accented look on your ceiling beams if the beams aren't white. Meanwhile, Coordinate Fabric Cord Cover adds an aesthetic look to your house. You can choose to either make them camouflage themselves or have them stand out on their own.
If you choose the hard covers, you can place your wires within them by measuring the length you need and cutting the covers accordingly. Then, slide the cover open and simply place the wires inside the covers before sliding them closed again.
If you use the fabric cover, you'll have better flexibility, which may or may not benefit you, depending on your design idea. You can simply allow the fabric wire covers to hang on the ceiling beams, or you can pin them in place for better security and more organization.
Using cord covers can efficiently and cheaply cover up those exposed ceiling wires. You can easily replace the covers, too, when you get tired of their color or design and pick new ones. Best of all, you can customize the covers themselves to however you want them.
You Can Opt For Wooden Moldings to Hide the Wires
For a more classic look and better camouflaging, you can opt for wooden moldings to hide ceiling wires. You can find wooden moldings in hardware stores, or you can make them yourself. These moldings can act as ceiling beam borders, and no one would know they hide wires.
They're great alternatives if you don't want to use plastic or fabric covers. However, they can cost more than buying covers and require more work. You'll need to attach the wooden moldings to the ceiling beams, and that would take time and some hard work. You can't easily change the moldings, too, if you come across a point where you want to.
You Can Use Decorative Boxes for Grouped Wires
Decorative boxes work great in covering exposed ceiling wires in groups. You can create a standard square box that will match your ceiling beams, or you can purchase cover plates like Arlington Boxes or Garvin Hole Cover on Amazon. Grouped wires are perfect for ceiling fans and light wires, but you may find that they look good even in places without grouped wires.
When Did the Trend of Exposed Ceilings Start?
Houses with exposed ceilings existed and had been the trend until the 1800s when lumber mills started producing wooden structures by the bulk. By the 1950s, people covered ceilings. By this time, the trend of the exposed ceilings faded, and clean, hidden ceilings were the new ideal.
However, with plenty of options now, such as faux exposed ceilings or even exposing previously hidden ceilings, the trend of exposed ceilings restarted once more by the early 2000s. Two types of exposed ceilings exist: decorative exposed ceilings and actual exposed ceilings.
Actual exposed ceilings rely on the beams to support the house, and no other material covers the ceilings. Meanwhile, decorative ceilings are just as they're called: decorative. You'll find that these houses already possess a covered ceiling and simply have additional beams to make it look like an exposed ceiling.
Some people create the exposed ceiling look themselves, but it's not quite recommended since most people use heavy beams that may cause strain on their ceiling. Meanwhile, others use lighter materials like fiberglass or plastic, and some people contact engineers or architects for advice.
Final Thoughts
You can hide wires in an exposed ceiling by painting the wires or your ceiling beams or using plastic or fabric cord covers, wooden molds, or decorative boxes. However, make sure your wires are safely in place to avoid any accidents.
You can do this by pinning them in place, except when you're using fabric covers. You can get away with not pinning your wires in that case. Also, remember not to hesitate if you think you need help. Commencing on a do-it-yourself project is great, but ensuring your safety should remain your priority.

Without that, your job will be run in parallel across the cluster. For typical coursework, it will probably be faster in local mode than distributed, but it's still worth getting experience running the way real Hadoop jobs would be run. For larger jobs parallelism definitely speeds things up.
You can watch what's going on in yarn by using "yarn top". You'll see -1 in some entries, because you only have the permissions to see details of your own job. Note that our copy of yarn only schedules memory. Every task is shown as using 1 vcore, no matter what it actually does. There's no maximum number of vcores, despite the implication that there is.
This system is set up for instrucional use. We need to be able to execute a number of jobs at the same time, to handle periods before assignments are due. That means that we've had to limit both the size of processes and the number running at the same time. The parameters are listed above.
You shouldn't need more than the resources we supply for course assignments. If you do, please consult your instructor.
You may be able to override these configurations, depending upon how your program is written. The main class has to include
extends Configured Implements Tool
and the run method has to use getConf()
Job job = new Job(getConf());
If you do that, then you can specify configuration arguments. Here's ann example from the examples program:
yarn jar /usr/hdp/2.6.3.0-235/hadoop-mapreduce/hadoop-mapreduce-examples.jar pi -Dmapreduce.job.running.map.limit=16 -Dmapreduce.job.running.reduce.limit=9 -Dmapreduce.job.reduces=9 -Dmapreduce.map.memory.mb=4096 -Dmapreduce.map.java.opts=-Xmx3481m 16 100000
Here is what the options do:
You may wonder why both mapreduce.map.memory.mb and mapreduce.map.java.opts are needed. mapreduce.map.memory.mb tells yarn how much memory to allocate to the process. mapreduce.map.java.opts tells Java how much memory to use. It's 3/4 the memory assigned because additional memory beyond this size is actually used by the task. The format of the two arguments is different: for the first, it's a number, which is interpreted as MB. For the second it's a standard JVM argument, typically something like -Xmx4g, for 4 G. The examples uses m, to make it easier to get the who parameters consistent.
If the amount of memory allocated is too small, your task will likely crash. When I saw this, there was no usable error message. It just stopped without producing usable output.
NOTE: During peridds when students are doing assignments, please restrict yourself to 24 G. During the summer, or the beginning of the term, you can use up to 75 G. The number of tasks doesn't matter: it's total memory that's the issue. However yarn won't schedule jobs with more than 20 G of memory for a single tasks (i.e. one map or reduce task). If you need more than 20 G, please contact _EMAIL_.
If you use these argumrnts, please watch with "yarn top" to verify that you have the number of containers and memory usage you expect.
Using a configuration file for a MapReduce job
If you want to specify options for your MapReduce job, but you don't like typing all the options each time, you can put the options in a file. For example, instead of
yarn jar /usr/hdp/2.6.3.0-235/hadoop-mapreduce/hadoop-mapreduce-examples.jar pi -Dmapreduce.job.running.map.limit=16 16 10000
you could use
yarn jar /usr/hdp/2.6.3.0-235/hadoop-mapreduce/hadoop-mapreduce-examples.jar pi -conf mapred.xml 16 10000
This probably isn't worth it for one option, but might be if you use many. Here's mapred.xml:
<?xml version="1.0"?>
<?xml-style type="text/xsl" href="configuration.xsl"?>
<configuration>
 <property>
 <name>mapreduce.job.running.map.limit</name>
 <value>16</value>
 </property>
</configuration>
Here's a second approach. Instead of "Job job = new Job(getConf());" use "Configuration conf = getConf()". Then you can use set to set parameters. E.g. conf.set("mapreduce.job.running.map.limit","16");
Here's a third approach: Create a simple shell script to run your program, e.g. create a file dopi.sh
#!/bin/sh
MRDIR=/usr/hdp/2.6.3.0-235/hadoop-mapreduce
yarn jar $MRDIR/hadoop-mapreduce-examples.jar pi -Dmapreduce.job.running.map.limit=16 16 10000
Now do "chmod +x" dopi.sh to make it executable. You can now run it by typing "./dopi.sh".
Technical informtion about the cluster
The Hadoop system is contained in 7 VMs, running on ilab1, ilab2 and ilab3 using KVM.
Because this cluster is intended for use in a student environment, Kerberos security is enabled on it. In order to do any operations you need Kerberos credentials. Our systems are set up to get credentials for you when you login, whether via ssh or the web tools.

doctor as an "authority" and be willing to stop driving.
The doctor also can contact the Department of Motor Vehicles and
request that the person be reevaluated.
- Take the Car Keys: If just having keys is
important to the person, substitute a different set of keys.
- Move the Car: If all else fails, disable the
car or move it to a location where the person cannot see it or gain
access to it.
Visiting the Doctor
Here are some tips for handling medical appointments:
- Schedule Wisely: Try to schedule the
appointment for the person's best time of day. Also, ask the office
staff what time of day the office is least crowded.
- Give Short Notice: Don't tell the person about
the appointment until the day of the visit or even shortly before
it is time to go. Be positive and matter-of-fact.
- Bring Snacks and Activities: Bring along
something for the person to eat and drink and any activity that he
- Bring a Helper: Have a friend or another
family member go with you on the trip, so that one of you can be
with the person while the other speaks with the doctor.

How to Use Counter Caches in Rails (Example)
Counter caches are great until you get 20,000 people following the same influencer and the counter cache on that person locks the whole database.
The goal of this post is to go through the basics of counter caches explaining possible alternatives to overcome this.
What are counter caches for?
Counter caches were created to cache the counts of associated records.
Imagine we are developing a social media application where we have influencers and fans:
Everytime we display an influencer in the list we want to show how many followers he has.
The naive approach to achieve this is doing a count of the associated fan records for each influencer.
While this might be enough if we are rendering only one influencer, it definitely does not scale well if we are going to render a list of many influencers, since it's going to trigger a select count query for each influencer.
In the logs we get:
… and goes on for each influencer…
That's when counter caches gain importance. Counter caches are a built in Rails feature that allows you to track the associated records count by doing almost nothing. It only requires you to add a new integer column in the influencers table and let the associated model know that it has to update that column every time a records gets created or destroyed (or is no longer referencing the influencer).
To use Rails counter caches you need to create a migration to add a new integer column to the associated model:
Let the FanInfluencer model know it has to update the counter cache in the influencer model:
Reset the counters for existing records with:
And then you are ready to use the new column like you would with any other attribute:
Using the new counter cache the db will execute only one query that will select the influencers to be rendered, since fans_count is now just a column on the influencer and no counts or joins with other tables are needed.
(Should you need more complex counter caches, consider using Counter culture gem that works around some deficiencies in Rails original counter caches.)
So… what's the problem?
Counter Caches have a fairly simple implementation using callbacks to keep this column updated. Every time a fan influencer record is created, updated, or destroyed, the counter cache on the corresponding influencer needs to get updated. This might make these type of operations slower. If that's a cost you can take, go ahead. But consider the following situation:
Imagine a very famous influencer has been advertised and suddenly all of our users click on 'Follow'. Every 'Follow' action on that influencer creates a fanInfluencer record, which will end in the db trying to execute many update queries to the counter cache of the influencer around the same time, locking up that db row and making our users requests time out. Ugh…
First solution. Use an SQL alternative to dynamically calculate the count without falling into the n+1 problem raised before introducing the counter caches.
We need to add the following scope on the influencer model:
When we load the influencers to render we need to use the new scope:
And then we just call fans_count for a particular influencer to get the counter.
In the logs we get:
This solution is slower than having the counter cache when rendering the influencer list since the latter one only has to select attributes of the same table. However, using this method you don't need to keep any counter cache column updated, making create/destroy/update actions on the fan_influencer table simpler since they don't trigger any callback afterwards. The db lock problem will go away.
So, this SQL alternative could be appropriate for you if:
 - You have many create/destroy/update actions on the fan_influencer table in comparison to requesting the influencers fans count.
 - Your app is prone to facing situations like the mentioned above, where the counter cache of a single record could get updated more times in a small period of time than it can handle.
Comparing the three approaches
We measured the time it took to request all the influencers each with his fans count using the three different approaches. In the db there were only 10 influencers and 1,000 fans, all the fans following all the influencers. The times are calculated as the average Active Record time of 5 runs.
Method #1: Using naive approach (fans.count)
Method #2: Using counter cache column
Method #3: Using SQL dynamic count
Second solution. Store the changes of the counter in a buffer in a faster storage first (like redis or Memcached) to later update the real value in the database.
After a fan_influencer record has been created or destroyed, the value in the redis cache for the influencer key is increased or decreased by one. After a couple of seconds, the count value for the redis key is added (or subtracted) to the counter cache in the db, and reset to 0.
A good idea is to also use a recalculation job once in a while, to make sure the counters are updated with the real count value, compensating for transient errors that may cause the deferred counters to drift from the actual value.
There are many gems that help you achieve this if you don't want to implement it yourself.
In this post it was used Wanelo gem to enqueue the jobs for me, but since it hasn't been committed to since Oct 7, 2016 you might want to implement that part yourself.
Next it's explained how to achieve this using that gem and assuming you have redis and a background worker installed. In this case it was used Delayed Jobs as the worker but you will see that it is very simple to modify the solution to use another one.
Start by configuring the gem with:
Let the fanInfluencer model know how to use the counter cache:
Create a method in the influencer to update the count to the real value
And here is where the fun part begins.
The gem adds a callback after a FanInfluencer record gets created or destroyed that triggers the enqueue method in the class called CCWorker as we configured before. So we need to create this class:
As you might have noticed, the enqueue method decides which Enqueuer class to delegate the execution to depending on the option 'cache'. Since the gem is the one that makes the calls to this method with the right arguments, we just need to implement those two modes knowing that we will receive two calls after a fanInfluencer has been created or destroyed: one for recalculation and one for deffered.
We can begin by creating the parent Enqueuer class, that decides if the job needs to be enqueued or if it's already pending.
We will now implement the deferred mode, for which we will define the 'execute' method that will be called by the asyncrhonous worker once the time is up. For this mode the gem comes with a counter class that does the buffering and updating part for us, so we just need to use it.
For the recalculation mode, we will call the method that we defined in the influencer at the begging, to reset the counter agains the real count. The name of this method comes in the options so we need to invoke it.
And that's it. Now we can try creating and destroying fans and influencers and we will see how their count changes after the number of seconds that we picked, and a recalculation job is enqueued for later.
To test it, we can create 100 fans that would follow Taylor Swift.
For each fanInfluencer created we can see logs like the following, where after the fanInfluencer record is created, two delayed jobs are inserted:
You can see in the redis cli console how the new keys are created, with the values 100 in the key for the buffer managed by the gem, and a 1 in the other two keys that mark the corresponding jobs as enqueued so they won't be enqueued again. In this case '104' that you see in the key name corresponds to the id of the influencer created.
After the 20 seconds (or whatever you configured for the env var) have passed, if you turned on your worker, we can see Taylor Swifts fans count has been raised.
To test the recalculation mode, we can update the fans count to any other incorrect value and wait until the recalculation method fixes it.
Notice that when using Delayed Jobs, since two jobs need to be enqueued (inserted into the db) after a fanInfluencer has been created, the 'follow' action is in total slower than before when no other 'follow' action is being performed at the same time. However, under big load the row contention problem does not happen, making this approach more efficient in that case.
Since the solution for the enqueuer does not depend on the influencer model, you can reuse it for any other counter cache that you may want to optimize, just by configuring the counter cache in the associated class and defining the recalculation method.

 Amazing, I implemented a similar solution in my company and now I'm writing a Gem to do it!
 Does this code has any license attached to it?

Sewage valves from the manufacturer to protect against backwater from the sewer system, to protect against insects and small animals from sewer systems and to protect against odours from sewer gases.
Valves for waste water to protect against backwater
Our Stop Silent Light valve (by Lasso Technik AG) is the optimal protection against water backflow. This valve for wastewater and rainwater is characterized by its ease of installation in industrial and private water systems. In addition, quick assembly in inspection shafts or evacuation pipes is ensured by a friction clamp inside the pipe. The check valve is ideally suited for back pressure up to 0.5 bar. The Stop Silent Light water valve can also be used as a nose flap (anti-frog) by preventing small animals from entering the pipe network. In order to prevent any gas from escaping from the cellar, this valve is also equipped with an airtight odour check valve.
Stop Silent Light waste water valves and their advantages
Waste water valve for preventing odour nuisance from the waste water system
Nose flap (anti-frog) to prevent small animals from entering the pipes
Reliable and durable protection against backflow of water
Simple and quick installation in pipes or inspection shafts without additional work
Functionality of our waste water valves
With an accumulation of wastewater, our backwater valve exerts pressure on the Stop Silent Light Membrane. The membrane opens its sealing lip upwards and releases the flow for the waste water. When the wastewater flow is stopped, the sealing lip is closed and the wastewater valve closes. In order to prevent sewage gases from escaping from the cellar, for example, the rubber membrane is filled and pressed against the pipe wall during the backflow.
Installation sizes of our waste water valves
Our Stop Silent Light waste water valves are available in the following installation sizes.
Inner pipe diameter:
Larger on request
Application examples of our waste water valves
Our waste water valves have a wide range of applications.

David Lucas was a mezzotint engraver. The eldest of seven children, he was born in 1802 to Charles Lucas, a farmer and his wife, Sarah. Lucas was a pupil of S. W. Reynolds who was also a mezzotint-engraver.
David Lucas Biography
Lucas was born in Geddington Chase, Northamptonshire, and he became a pupil of Samuel William Reynolds after the chance encounter in 1820.
David Lucas moved to London as an apprentice and had produced his work by 1827.
David Lucas Life and His Work
In 1829, David Lucas moved to London to work as an apprentice and produced his own work by 1827.
Lucas was the protege of John Constable who was a reputed artist in the field. Constable had collaborated with Lucas numerous nubs of tamest illustrate 'chiaroscuro of nature'.
Facts About David Lucas
Lucas' meeting with Constable happened when the former presented two samples of mezzotint engraving to the latter, who was so impressed that he took him on as an assistant for Constable's book.
By 1829 Lucas knew John Constable, and he worked intensively on engravings for Constable's Various Subjects such as Landscape, the Characteristic of English Scenery from 1830 to 1832. After the Constable died in 1837, he continued to produce works for the family
The Proposed Appendix to English Landscape Scenery issued by Moon prints in 1838, was also an example of a single published.
Same as Lucas's 'Large Single Prints' and it prints from Lucas's New Series of Engravings, illustrative of English Landscape, from the Pictures of John Constable published in 1846
David Lucas Books
The book was is Constable's Various Subjects of Landscape, Characteristic of English Scenery for which Lucas worked from 1830 to 1832.
After Constable's death, Lucas continued to produce engravings and artwork for the family. He died in 1881 in a workhouse in Fulham.


42.defined; # True
Very few types (like Failure) override defined to return False even for instances:
sub fails() { fail 'oh noe' };
say fails().defined; # False
routine isa
multi method isa(Mu $type) returns Bool:D
multi method isa(Str:D $type) returns Bool:D
Returns True if the invocant is an instance of class $type, a subset type or a derived class (through inheritance) of $type.
my $i = 17;
say $i.isa("Int"); # True
say $i.isa(Any); # True
A more idiomatic way to do this is to use the smartmatch operator ~~ instead.
my $s = "String";
say $s ~~ Str; # True
routine Bool
multi sub Bool(Mu) returns Bool:D
multi method Bool() returns Bool:D
Returns False on the type object, and True otherwise.
Many built-in types override this to be False for empty collections, the empty string or numerical zeros
say Mu.Bool; # False
say Mu.new.Bool; # True
say [1, 2, 3].Bool; # True
say [].Bool; # False
say { 'hash' => 'full'}.Bool; # True
say {}.Bool; # False
method Str
multi method Str() returns Str
Returns a string representation of the invocant, intended to be machine readable. Method Str warns on type objects, and produces the empty string.
say Mu.Str; #!> use of uninitialized value of type Mu in string context
routine gist
multi sub gist(Mu) returns Str
multi method gist() returns Str
Returns a string representation of the invocant, optimized for fast recognition by humans. As such lists will be truncated at 100 elements. Use .perl to get all elements.
The default gist method in Mu re-dispatches to the perl method for defined invocants, and returns the type name in parenthesis for type object invocants. Many built-in classes override the case of instances to something more specific that may truncate output.
gist is the method that say calls implicitly, so say $something and say $something.gist generally produce the same output.
say Mu.gist; # (Mu)
say Mu.new.gist; # Mu.new()
routine perl
multi sub perl(Mu) returns Str
multi method perl() returns Str
Returns a Perlish representation of the object (i.e., can usually be re-evaluated with EVAL to regenerate the object). The exact output of perl is implementation specific, since there are generally many ways to write a Perl expression that produces a particular value
method clone
method clone(*%twiddles)
Creates a shallow clone of the invocant. If named arguments are passed to it, their values are used in every place where an attribute name matches the name of a named argument.
class Point2D {
 has ($.x, $.y);
 multi method gist(Point2D:D:) {
 "Point($.x, $.y)";
 }
}
my $p = Point2D.new(x => 2, y => 3);
say $p; # Point(2, 3)
say $p.clone(y => -5); # Point(2, -5)
method new
multi method new(*%attrinit)
Default method for constructing (create + initialize) new objects of a class. This method expects only named arguments which are then used to initialize attributes with accessors of the same name.
Classes may provide their own new method to override this default.
new triggers an object construction mechanism that calls submethods named BUILD in each class of an inheritance hierarchy, if they exist. See the documentation on object construction for more information.
method bless
method bless(*%attrinit) returns Mu:D
Lower-level object construction method than new.
Creates a new object of the same type as the invocant, uses the named arguments to initialize attributes, and returns the created object.
You can use this method when writing custom constructors:
class Point {
 has $.x;
 has $.y;
 multi method new($x, $y) {
 self.bless(:$x, :$y);
 }
}
my $p = Point.new(-1, 1);
(Though each time you write a custom constructor, remember that it makes subclassing harder).
method CREATE
method CREATE() returns Mu:D
Allocates a new object of the same type as the invocant, without initializing any attributes.
say Mu.CREATE.defined; # True
method print
multi method print() returns Bool:D
Prints value to $*OUT after stringification using .Str method without adding a newline at end.
"abc\n".print; # abc␤
method put
multi method put() returns Bool:D
Prints value to $*OUT after stringification using .Str method adding a newline at end.
"abc".put; # abc␤
method say
multi method say() returns Bool:D
Prints value to $*OUT after stringification using .gist method with newline at end. To produce machine readable output use .put.
say 42; # 42␤
method ACCEPTS
multi method ACCEPTS(Mu:U: $other)
ACCEPTS is the method that smart matching with the infix ~~ operator and given/when invokes on the right-hand side (the matcher).
The Mu:U multi performs a type check. Returns True if $other conforms to the invocant (which is always a type object or failure).
say 42 ~~ Mu; # True
say 42 ~~ Int; # True
say 42 ~~ Str; # False
Note that there is no multi for defined invocants; this is to allow autothreading of junctions, which happens as a fallback mechanism when no direct candidate is available to dispatch to.
method WHICH
multi method WHICH() returns ObjAt:D
Returns an object of type ObjAt which uniquely identifies the object. Value types override this method which makes sure that two equivalent objects return the same return value from WHICH.
say 42.WHICH eq 42.WHICH; # True
method WHERE
method WHERE() returns Int
Returns an Int representing the memory address of the object.
method WHY
multi method WHY()
Returns the attached Pod value. For instance,
 sub cast(Spell $s)
 #= Initiate a specified spell normally
 #= (do not use for class 7 spells)
 {
 do-raw-magic($s);
 }
 say &cast.WHY;
prints
Initiate a specified spell normally (do not use for class 7 spells)
See the documentation specification for details about attaching Pod to variables, classes, functions, methods, etc.
trait is export
multi sub trait_mod:<is>(Mu:U \type, :$export!)
Marks a type as being exported, that is, available to external users.
my class SomeClass is export { }
A user of a module or class automatically gets all the symbols imported that are marked as is export.
See /language/modules#Exporting_and_Selective_Importing for more details.
method take
method take()
Takes the given item and passes it to the enclosing gather block.
#| randomly select numbers for lotto
my $num-selected-numbers = 6;
my $max-lotto-numbers = 49;
gather for ^$num-selected-numbers {
 take (1 .. $max-lotto-numbers).pick(1);
}.say; #-> 32 22 1 17 32 9 (for example)
method so
method so()
Returns a Bool value representing the logical non-negation of an expression. One can use this method similarly to the English sentence: "If that is so, then do this thing". For instance,
my @args = <-a -e -b -v>;
my $verbose-selected = any(@args) eq '-v' | '-V';
if $verbose-selected.so {
 say "Verbose option detected in arguments";
} #-> Verbose option detected in arguments
method not
method not()
Returns a Bool value representing the logical negation of an expression. Thus it is the opposite of so.
my @args = <-a -e -b>;
my $verbose-selected = any(@args) eq '-v' | '-V';
if $verbose-selected.not {
 say "Verbose option not present in arguments";
} #-> Verbose option not present in arguments
Since there is also a prefix version of not, the above code reads better like so:
my @args = <-a -e -b>;
my $verbose-selected = any(@args) eq '-v' | '-V';
if not $verbose-selected {
 say "Verbose option not present in arguments";
} #-> Verbose option not present in arguments

The modeling of residual stresses induced by drilling remains an issue. Indeed, even if some models are under development, their validation is limited by the absence of universal characterization method of residual stresses inside the hole. This paper aims at presenting a procedure to characterize the residual stress profile induced by drilling. The principle is based on the preparation of a reference sample that has been pre-heat treated in order to remove bulk residual stresses without modifying the microstructure. Then the sample is instrumented with strain gauges before being cut in two parts. This enables on one hand to estimate the elastic recovery after the cut and on the other hand to provide an easy access to the investigated surface. Finally a standard X-Ray diffractometer and an electropolishing technique are combined to estimate residual stresses profiles in two directions (circumferential and axial directions). Some numerical analyses are also performed to estimate stress relaxation during thermal treatment and during sample cutting to give a better interpretation of measurements.

Steam Play
Before we understand what Steam Play is, let's check some prerequisites…
Wine, originally an acronym for "Wine Is Not an Emulator", is a compatibility layer capable of running Windows applications on several POSIX-compliant operating systems such as Linux, macOS and BSD. Instead of simulating internal Windows logic like a virtual machine or emulator, Wine translates Windows API calls into POSIX calls on-the-fly, eliminating the performance and memory penalties of other methods and allowing you to cleanly integrate Windows applications into your desktop.
Wine is an open-source technology and can be downloaded for free. CrossOver is commercialized version of Wine from CodeWeavers.
Proton, a tool released by Valve Software and CodeWeavers, allows games which are exclusive to Windows to run on the Linux operating system. It uses a custom version of Wine as well as additional libraries developed alongside it to facilitate this. These include Direct3D to Vulkan translation layers, namely DXVK for Direct3D 9, 10 and 11 and VKD3D for Direct3D 12.
Vulkan is 3D rendering API, successor of OpenGL. Vulkan offers lower overhead, more direct control over the GPU, and lower CPU usage. The overall concept and feature set of Vulkan is similar to Mantle later adopted by Microsoft with Direct3D 12 and Apple with Metal.
Steam Play
Steam Play is compatibility layer built into the official Steam client that allows you to play games from your library that were built for other operating systems. For example, Steam Play uses Proton to allow Linux users to play Windows games.
DOSBox emulates an IBM PC compatible computer running a DOS operating system including many IBM PC compatible graphics and sound cards. This means that original DOS programs and games are provided with an environment in which they can run correctly, even though modern computers have dropped support for the old environment.
Boxtron is Steam Play compatibility tool to run DOS games using native Linux DOSBox. It enables you to play games on Linux that don't have a Linux build setup on Steam only this is for DOSBox games.

A nonlinear circuit model of the GaAs MESFET is developed by extracting circuit parameters from dc and small-signal RF measurements in a systematic manner. The circuit model is then analyzed by an efficient algorithm called the modified multiple-reflection method. For the first time, this method is applied to MESFET circuit analysis. Compared with the original multiple-reflection method, the modified multiple-reflection method shows a dramatic increase in convergence speed. The validity of the nonlinear MESFET model is confirmed by comparing the simulation results with experimental data.


Functional Improvisation, 2017
by Terry Day and Marcus Coates
Performance at William Morris Museum, London
Commissioned by Create, London
Audience members were invited to bring to the performance a question they have struggled to answer for themselves. Using improvised percussion by Terry Day and movement and vocalisation by Marcus Coates, they worked together to create a combined language that aimed to respond pragmatically to these questions. Their use of improvised performance as a socially functional tool is an attempt to employ their disciplines as complex and purposeful modes of expression. The forms of performance that they inhabit offers them a route to non-conscious understanding through physical activity and play, a method that expands the possibilities of creative thinking, bringing thought into the realm of movement and sound making. Their aim is to work for the audience, to create performances that are insightful, offering new reflections on the questions and possible answers.
Questions included:
Why is the world so angry?
What is good enough?
How do we find certainty, or do we?
Should art always be actively challenging?
