Spider web tattoos, as we'll discover, are riddled with symbolism, often as complex as the webs they represent. They may appear as simple designs at first glance, but the beauty of these intricate patterns is that they can conceal layers of meaning. Whether it's a tribute to the tangled threads of fate, a nod to resilience, or even a symbol of connection, each spider web tattoo is as unique as the soul wearing it.
Prepare to plunge into a kaleidoscope of ideas, punctuated with vivid pictures that will light up your imagination like a firefly. By the time you reach the end of this blog post, you'll be a connoisseur of spider web tattoos, able to decipher the various interpretations and appreciating the artistic prowess that goes into creating such a masterpiece.
So, ready to spin a yarn with me? Let's dive into the mysterious realm of spider web tattoos and unravel their hidden secrets together. Because as we all know, even the smallest of webs can tell the grandest of stories.
What Does a Spider Web Tattoo Mean or Represent?
Spider web tattoos often raise eyebrows and elicit a flurry of questions. While they've been painted with a rather unflattering brush in popular culture, often associated with darker elements, I've found that there's always more than meets the eye.
Let's rewind a bit to the first spider web tattoo I ever did. I remember my client, a young woman who'd just graduated college, explained that for her, the spider web represented the myriad connections and relationships she'd forged during her studies. It was an embodiment of the complex ecosystem that her life had evolved into. And so, that first web that I wove on her skin was a tribute to life, resilience, and the many intricate connections that define us.
Symbolism: A Diverse Spectrum & Cycle of Life
Spider web tattoos, much like life itself, can represent the 'sticky' situations we often find ourselves in. In several mythologies, the spider is revered as the architect of life, death, and destiny. To me, these tattoos are a testament to our adaptability. When life tears down our web, just as a spider would, we pick up the pieces and weave them into a new story, a new beginning.
An Uncomfortable History
Let's not ignore the elephant in the room – the spider web tattoo's long-standing association with incarceration. These designs started gaining traction in prisons in the 1970s and 1980s, often symbolising time served. However, it's also essential to acknowledge its darker past tied to white supremacist groups, which has painted a negative image.
Native American Roots
Native American culture has a rich history with spider web symbolism, often linked to the Spider Woman spirit who weaves protective webs over newborns. As tattoos, they can symbolize a form of spiritual protection.
Public Perception: The Tattoo Paradox
The dichotomy of spider web tattoos is fascinating – it can simultaneously carry both positive and negative connotations. While some may view it negatively, many today appreciate the intricate design for its artistic and symbolic value. But if you're considering getting one, it's crucial to be aware of the various interpretations and potential perceptions.
Other Symbols Used With the Web
As complex as the webs they represent, spider web tattoos often intertwine various symbols, each adding another layer of meaning. The most popular choice is, of course, the spider, often depicted as a Black Widow, representing power, strength, and in some cases, a brush with death.
Other symbols can include anything from stars, hearts, or butterflies, to gothic symbols like bats and coffins, each transforming the web's meaning and adding a personal touch to the design.
Things to Consider Before Getting a Tattoo
Before stepping into my studio or any other, there's one piece of advice I always share: Understand your tattoo and its meaning fully. Impulsive tattoos often lead to regret later on, and you want your ink to be a reflection of who you are, not a decision made on a whim.
A spider web tattoo, in particular, has both positive and negative connotations, so it's vital to comprehend these meanings before making your decision. After all, a tattoo is a lifelong commitment, and you want to be completely confident in your choice.
In the grand scheme of tattoos, spider web designs are truly a work of art, and with careful consideration, they can become a unique and meaningful addition to your personal story. So remember, take your time, do your research, and ensure your tattoo will not just adorn your body, but resonate with your spirit too.
And there we have it, friends – a deep dive into the mesmerizing world of spider web tattoos. Remember, these intricate designs are as multifaceted as the stories they represent, so take the time to truly understand what you're inking onto your skin. While they come with their share of historical baggage, the beauty of tattoos is in their adaptability to personal meanings. So, if a spider web tattoo resonates with you, don't be afraid to explore it. Just be prepared to handle potential misconceptions with grace and confidence, armed with the knowledge you've gathered. Your body is a canvas and your tattoos are the stories you choose to tell. So, make those stories count and weave a web that is uniquely, unapologetically, you. Happy inking!

In one piece of promotional advertising for this southern German River town, I read that it was one of the seven most beautiful cities in the world! This is a big call to live up to, particularly if you ask difficult questions about the criteria involved in such a judgement. For example, you could ask,
 - What size does an urban centre have to be to be adjudged as a city in the first place
 - What are the other cities Passau is comparing itself with?
Passau's population is 50000 so I am wondering if the other six most beautiful cities that made the list include cities like New York, Paris and London which have populations of over a million citizens.
When considering the 'beauty' of a city, you need some clear guidelines. Here are some suggestions.
 1. Does the geography of the 'city' enhance its beauty…for example, beautiful harbours, sea-shores, rivers or mountain ranges nearby?
 2. Does the historical background add to the interest of visiting this city?
 3. Beautiful architecture? Does it have old centres of Baroque places or modernist masterpieces?
 4. Does it have an artistic and cultural life exemplified by its galleries and museums?
 5. Is its infrastructure accessible and efficient to create a welcoming culture for visitors?
When I decided to apply these guidelines to Passau to check its self-rating, I decided it passed the first one, location, with flying colours. Its old centre is built at the confluence of not just two rivers, which would be unusual, but of three. The old town looks like the prow of a boat forging ahead down stream as it navigates its way through Germany and Austria. Its major river is the Danube which is supported by two other important rivers, the Ilz from the south and the Inn from the north. Passau also has the backdrop of a minor mountain with its own castle (check image at start of article) from which the visitor can gaze down upon the convergence of these three rivers and note that they are colour coded; green, gray and the poorly named Blue (Brown!) Danube. The only ill-mannered comment an Australian might make is that it is no Sydney Harbour.
IMGP5200 2
Passau certainly has an extensive history. There is evidence that the Celts settled here 2500 years ago and its location at the junction of three rivers ensured that the Romans claimed the spot to ensure control of this reach of the Danube River. One distinctive aspect of Passau's long history is that it fell into the hands of Prince/Bishops of the Catholic Church who ruled a large area around Passau for hundreds of years from the 10th century. Great wealth from passing traders, particularly from salt (white gold!) meant that these clerical rulers became very wealthy.
Any German town or city in the twentieth century couldn't avoid being touched by the rise of National Socialism in the 1930s and the many side effects of War with your neighbours from 1938 to 1945. However Passau has its own specific link with that period that its citizens have mixed feelings about. Their town was the early childhood home of Adolph Hitler from 1889 to 1894. There is a curious story about Hitler's childhood in Passau that has emerged in the new millenium.
"Everyone in Passau knew the story. Some of the other stories told about him were that he never learned to swim and needed glasses," she wrote. "In 1894, while playing tag with a group of other children, the way many children do in Passau to this day, Adolf fell into the river. The current was very strong and the water ice cold, flowing as it did straight from the mountains. Luckily for young Adolf, the son of the owner of the house where he lived was able to pull him out in time and so saved his life."
Hitler told his Nazi generals that he used to play cowboys and Indians on the banks of the river but never admitted to falling in the water. (Amy Willis 2002)
The web of history is made from delicate skeins; what would have been the result for Europe if the young Adolf hadn't been saved by his neighbour?
Another link to the major events of the 1930's in Germany was brought about by Passau's geographical location on the Danube with its proximity to the Austrian border. When the Nazis were wooing their Austrian neighbours to the idea of joining with their German-speaking neighbours in a combined German Reich in 1933, they invited Austrians to vote in the German elections. Huge numbers were bused in to Passau to vote. It was only five years later that Hitler began his triumphal procession through Austria to celebrate the 'merger' of the two countries.
Unlike so many other Bavarian cities and towns, Passau's location has meant that it wasn't significant enough to the Western allies to suffer the extensive damage that other German cities suffered as a result of the wars of the twentieth century. Unlike cities in northern Germany, it didn't have to rebuild from scratch its historic centre after 1945. However much of the inner city did burn down in the 17th century and it was rebuilt in an Italian Baroque style chosen by the wealthy Prince-Bishop of the time. Apparently he decided the walls should extend beyond the roof-line so the winter snow would be stopped before it fell on innocent passer-byes.
IMGP5128 2 IMGP5129 2 IMGP5180 2
My third criteria for a beautiful city is its architecture and street-scape and there is no doubt that Passau is a beautiful place to stroll around. The old centre is surrounded by water on three sides so its old streets and narrow alley ways are a delight to wander through; on our visit to Passau, we started from the Danube, crossed to the other side of the city in five minutes to the Inn river Passau, Bavariaand then plunged back into the maze of streets. The predictable disadvantage of Passau's location is that when the rivers are in flood, damage from water inundation from three sides is particularly tragic. In 2013, the city suffered the worst flood in 500 years where the citizens were cut off, with the river lapping over their high bridges. The National news outlet, Spiegel described the crisis as follows…
The streets of Passau have been transformed into canals, full of soldiers evacuating pensioners in rubber boats. …Many bizarre scenes are playing out in the "City of Three Rivers," which is usually so proud of its location right where the Danube, Inn and Ilz rivers meet. Streetlights are bobbing on the water surface like buoys and an abandoned, half-submerged car is blinking furiously, its alarm system triggered by its movement in the water.IMGP5183 2
The image to right shows the 2013 flood was above the door of the Town Hall but not the highest flood in the history of Passau.
The centre of town and the most significant piece of architecture in Passau is St Stephens Basilica. Curiously two of the major cities down stream, Vienna and Budapest, have cathedrals also named after St Stephen. St Stephen's Passau is named after the first Christian martyr who was stoned to death outside a gate in Jerusalem while the adolescent St Paul held the cloaks of the outraged Pharisees. One of the themes of tour guides in Passau and in the sculpture st stephensneighbouring Central European cities was their unease with the dark history that they have inherited from earlier generations. Most we met were determined both to acknowledge and learn from their difficult past. In the case of St Stephen's in Passau, this is beautifully done by the sculpture that sits right at the front of the church behind the altar. It presents a series of individuals caught in the process of gathering around an individual and participating in the stoning of the innocent outsider. St Stephen was an outsider in that he was a follower of Jesus of Nazareth, something unacceptable to the dominant religion of that city and so this outsider must be stoned for his sins against cultural orthodoxy. The link with what happened to the Jews in Germany in the first half of the twentieth century is explicitly made by the stance of the individuals in this sculpture; there is even a Pauline figure holding the cloaks of the perpetrators throwing rocks at the Jewish stranger/neighbour.
IMGP5165 2
My fourth criteria for beautiful cities asks whether the contender has an artistic and cultural life exemplified by its galleries and museums. On our short visit to Passau, we certainly weren't tempted to visit any significant galleries to art or local culture; the closest we came was to slowly bypass the Museum of Glass. We were tempted to visit the castle on the hill overlooking the three rivers but only for the magnificent views of the rivers and the rolling green hills that surrounded the modern parts of Passau.
Given that we came by Riverboat, we were in no situation to comment on the accessibility to efficient local transport facilities.
In attempting to come to a judgement based on my five 'beautiful' criteria, I would have to cast doubt on the locals' claim that Passau was one of the seven most beautiful cities in the world. Apart from making rash claims about their world urban standing, I would never question anyone's claim that Passau was indeed a beautiful city. We thoroughly enjoyed our trip to this small river city in southern Germany, particularly for the stroll through the cobble-stoned alley ways and the fantastic

- Print factsheet
Whitehead's spiny rat description
Named after the British explorer John Whitehead who first documented its existence (3), Whitehead's spiny rat (Maxomys whiteheadi) has reddish-brown upperparts with grey underfur (2) (4). As its name suggests, Whitehead's spiny rat also has numerous inflexible grey spines with black tips on its upperparts, which are thought to be for protection. The underparts are orange-buff with grey underfur and numerous soft, pale spines (4) (5).
The tail, which is shorter than the head and body length combined, is bicoloured, with a brown-black upperside separated from a white underside by a sharp line (6).
Male Whitehead's spiny rats generally have longer hindfeet than females. This species of rat has the largest teeth of all Maxomys species. Six subspecies of Whitehead's spiny rat are currently recognised, all of which differ slightly in appearance (7).
- Also known as
- Whitehead's sundaic maxomys. Top

Whitehead's spiny rat biology
Whitehead's spiny rat is believed to be monogamous, with each breeding pair occupying a home range that is defended against other spiny rats (8). It is believed to breed throughout the year, at least in peninsular Malaysia, and has one to six young per litter (5).
A nocturnal animal (8), Whitehead's spiny rat spends its nights foraging on the forest floor for a wide range of plant material, such as fallen fruits and seeds, with a preference for oil palm fruit (10). However, as an omnivorous species, its diet also includes arthropods (8). Like other spiny rats, it is a hoarder, storing seeds in deep underground burrows that are dug by other forest animals (11).
Whitehead's spiny rat is eaten by a number of predators, including the leopard cat (Prionailurus bengalensis) (9).Top
Whitehead's spiny rat range
Whitehead's spiny rat is native to Southeast Asia, ranging from peninsular Thailand south to Malaysia, Indonesia and Brunei. This includes the islands of Borneo and Sumatra, as well as various neighbouring islands (1).Top
Whitehead's spiny rat habitat
Belonging to a genus of rodents which are the most common in Southeast Asian tropical forests, Whitehead's spiny rat is found in old undisturbed areas of forest (8), as well as areas that have re-grown following a disturbance (secondary forest) (9). This ground-dwelling spiny rat also inhabits rice paddies and gardens adjacent to forests (8). Although generally a lowland species, Whitehead's spiny rat has been recorded at elevations as high as 2,100 metres on the slopes of Mount Kinabalu (1).Top
Whitehead's spiny rat status
Whitehead's spiny rat is classified as Vulnerable (VU) on the IUCN Red List (1).Top
Whitehead's spiny rat threats
The main threat to Whitehead's spiny rat is the widespread loss of habitat on Sumatra and Borneo (1), as a result of commercial logging and agriculture, particularly oil palm plantations (12). Lowland forests have been particularly hard hit, with some predicting that if this rate of deforestation continues, lowland forest in Sumatra and Kalimantan (Indonesian Borneo) may soon disappear completely (12).Top
Whitehead's spiny rat conservation
Although there are no known specific conservation measures currently in place for Whitehead's spiny rat, it occurs in the protected area of the Mount Kinabalu National Park, Borneo. A number of conservation organisations, such as WWF, are working to conserve forest in the region this endangered species inhabits (1) (13).Top

Understanding how to evacuate pods on nodes
Evacuating pods allows you to migrate all or selected pods from a given node or nodes.
You can only evacuate pods backed by a replication controller. The replication controller creates new pods on other nodes and removes the existing pods from the specified node(s).
Bare pods, meaning those not backed by a replication controller, are unaffected by default. You can evacuate a subset of pods by specifying a pod-selector. Pod selectors are based on labels, so all the pods with the specified label will be evacuated.
Procedure
 1. Mark the nodes unschedulable before performing the pod evacuation.
 1. Mark the node as unschedulable:
 $ oc adm cordon <node1>
 Example output
 node/<node1> cordoned
 2. Check that the node status is NotReady,SchedulingDisabled:
 $ oc get node <node1>
 Example output
 NAME STATUS ROLES AGE VERSION
 <node1> NotReady,SchedulingDisabled worker 1d v1.19.0
 2. Evacuate the pods using one of the following methods:
 - Evacuate all or selected pods on one or more nodes:
 $ oc adm drain <node1> <node2> [--pod-selector=<pod_selector>]
 - Force the deletion of bare pods using the --force option. When set to true, deletion continues even if there are pods not managed by a replication controller, replica set, job, daemon set, or stateful set:
 $ oc adm drain <node1> <node2> --force=true
 - Set a period of time in seconds for each Pod to terminate gracefully, use --grace-period. If negative, the default value specified in the Pod will be used:
 $ oc adm drain <node1> <node2> --grace-period=-1
 - Ignore DaemonSet-managed pods using the --ignore-daemonsets flag set to true:
 $ oc adm drain <node1> <node2> --ignore-daemonsets=true
 - Set the length of time to wait before giving up using the --timeout flag. A value of 0 sets an infinite length of time:
 $ oc adm drain <node1> <node2> --timeout=5s
 - Delete pods even if there are pods using emptyDir using the --delete-local-data flag set to true. Local data is deleted when the node is drained:
 $ oc adm drain <node1> <node2> --delete-local-data=true
 - List objects that will be migrated without actually performing the evacuation, using the --dry-run option set to true:
 $ oc adm drain <node1> <node2> --dry-run=true
 Instead of specifying specific node names (for example, <node1> <node2>), you can use the --selector=<node_selector> option to evacuate pods on selected nodes.
 3. Mark the node as schedulable when done.
 $ oc adm uncordon <node1>
Understanding how to update labels on nodes
You can update any label on a node.
Node labels are not persisted after a node is deleted even if the node is backed up by a Machine.
Any change to a MachineSet is not applied to existing machines owned by the MachineSet. For example, labels edited or added to an existing MachineSet are not propagated to existing machines and Nodes associated with the MachineSet.
 - The following command adds or updates labels on a node:
 $ oc label node <node> <key_1>=<value_1> ... <key_n>=<value_n>
 For example:
 $ oc label nodes webconsole-7f7f6 unhealthy=true
 - The following command updates all pods in the namespace:
 $ oc label pods --all <key_1>=<value_1>
 For example:
 $ oc label pods --all status=unhealthy
Understanding how to mark nodes as unschedulable or schedulable
By default, healthy nodes with a Ready status are marked as schedulable, meaning that new pods are allowed for placement on the node. Manually marking a node as unschedulable blocks any new pods from being scheduled on the node. Existing pods on the node are not affected.
 - The following command marks a node or nodes as unschedulable:
 Example output
 $ oc adm cordon <node>
 For example:
 $ oc adm cordon node1.example.com
 Example output
 node/node1.example.com cordoned

 NAME LABELS STATUS
 node1.example.com _URL_=node1.example.com Ready,SchedulingDisabled
 - The following command marks a currently unschedulable node or nodes as schedulable:
 $ oc adm uncordon <node1>
 Alternatively, instead of specifying specific node names (for example, <node>), you can use the --selector=<node_selector> option to mark selected nodes as schedulable or unschedulable.
Configuring master nodes as schedulable
You can configure master nodes to be schedulable, meaning that new pods are allowed for placement on the master nodes. By default, master nodes are not schedulable.
You can set the masters to be schedulable, but must retain the worker nodes.
You can deploy OKD with no worker nodes on a bare metal cluster. In this case, the master nodes are marked schedulable by default.
You can allow or disallow master nodes to be schedulable by configuring the mastersSchedulable field.
Procedure
 1. Edit the schedulers.config.openshift.io resource.
 $ oc edit schedulers.config.openshift.io cluster
 2. Configure the mastersSchedulable field.
 apiVersion: _URL_
 kind: Scheduler
 metadata:

 spec:
 mastersSchedulable: false (1)
 policy:
 name: ""
 status: {}
 1 Set to true to allow master nodes to be schedulable, or false to disallow master nodes to be schedulable.
 3. Save the file to apply the changes.
Deleting nodes
Deleting nodes from a cluster
When you delete a node using the CLI, the node object is deleted in Kubernetes, but the pods that exist on the node are not deleted. Any bare pods not backed by a replication controller become inaccessible to OKD. Pods backed by replication controllers are rescheduled to other available nodes. You must delete local manifest pods.
Procedure
To delete a node from the OKD cluster, edit the appropriate MachineSet:
If you are running cluster on bare metal, you cannot delete a node by editing MachineSets. MachineSets are only available when a cluster is integrated with a cloud provider. Instead you must unschedule and drain the node before manually deleting it.
 1. View the MachineSets that are in the cluster:
 $ oc get machinesets -n openshift-machine-api
 The MachineSets are listed in the form of <clusterid>-worker-<aws-region-az>.
 2. Scale the MachineSet:
 $ oc scale --replicas=2 machineset <machineset> -n openshift-machine-api
For more information on scaling your cluster using a MachineSet, see Manually scaling a MachineSet.
Deleting nodes from a bare metal cluster
When you delete a node using the CLI, the node object is deleted in Kubernetes, but the pods that exist on the node are not deleted. Any bare pods not backed by a replication controller become inaccessible to OKD. Pods backed by replication controllers are rescheduled to other available nodes. You must delete local manifest pods.
Procedure
Delete a node from an OKD cluster running on bare metal by completing the following steps:
 1. Mark the node as unschedulable:
 $ oc adm cordon <node_name>
 2. Drain all pods on your node:
 $ oc adm drain <node_name> --force=true
 3. Delete your node from the cluster:
 $ oc delete node <node_name>
Although the node object is now deleted from the cluster, it can still rejoin the cluster after reboot or if the kubelet service is restarted. To permanently delete the node and all its data, you must decommission the node.
Adding kernel arguments to nodes
In some special cases, you might want to add kernel arguments to a set of nodes in your cluster. This should only be done with caution and clear understanding of the implications of the arguments you set.
Improper use of kernel arguments can result in your systems becoming unbootable.
Examples of kernel arguments you could set include:

text: Because of the conservation of angular momentum, the atmospheric winds and the mass exchange between the Martian ice caps and atmosphere, associated with the sublimation/condensation process (mainly CO2), induce seasonal effects on Mars' polar motion, nutation, and length of day (LOD). These effects are computed using the output of a global circulation model of the Martian atmosphere, providing atmospheric pressure fields, ice cap surface pressure fields, and zonal as well as meridional winds. For the LOD variations, total amplitudes (CO2 and wind effects) of 0.22 ms for the annual wave and of 0.38 ms for the semiannual wave are obtained. These amplitudes are more than one order of magnitude larger than the LOD variations induced by the zonal tides, which are at the level of 10 μs. For the induced polar motion the annual amplitude is ~11 milliarcseconds (mas), and the semiannual amplitude is ~3 mas. The effect on the nutations, related to the diurnal forcing, is at the level of 0.1 mas. The differences between the results for a liquid and for a solid core are examined and shown to be <1% of the total effects.

Filtering sequences
The filter expression is used to filter sequences. Filters are commonly used in combination with path expressions to create more precise selectors.
Context item expression
Before you can get started with filters, you'll need to know what a context item expression is and how it works. It is a very simple expression, but very useful while filtering sequences.
The context item expression consists of a single dot ("."). It evaluates to the context item. It will raise a dynamic error (XPDY0002) if the context is absent.

Filter expression
A filter expression consists of a base expression and a predicate. The base expression will be evaluated first. This will result in an input sequence that will be filtered. The predicate is an expression written in square brackets ("[" and "]") and directly follows the base expression. You can identify filter expressions by these square brackets.
Predicate
Since the predicate is an expression, it can be evaluated. It will be evaluated for each item in the input sequence. The predicate is evaluated with an inner focus. This means that:
 - The context item is the item currently being tested;
 - The context size is the number of items in the input sequence;
 - The context position is the position of the context item within the input sequence.
Predicate truth
The predicate may return anything since it is just a regular expression. The result of the predicate is turned into an xs:boolean value. This value is called the predicate truth value. If the predicate truth value is true, the item for which the predicate is evaluated will be kept. If the predicate truth value is false, the item for which the predicate is evaluated will be discarded.
The predicate truth value is determined by applying two rules to the result of the predicate. First, if the result is a singleton atomic value of a numeric type or derived from a numeric type, the predicate truth value is true if the result is equal to the context position, and false otherwise. For all other data types, the predicate truth is the effective boolean value of the result.
Ordering
The ordering of the resulting sequence is the same as the ordering of the input sequence.
Examples
Whew, that was a lot of information. Here are some examples of filter expressions.
Filtering atomic values
This is a short example. The base expression creates a sequence of xs:integer values using a range expression. The filter will keep every item with a value greater than 5. As you can see here, the context item is used to compare the value of each individual item in the input sequence.

Ordering of items
This short example shows that the ordering of items in the input sequence is the same as the ordering in the resulting sequence. The predicate will be false for every value that is an odd value.
Other

Open example in playground
Accessing members of a sequence
You may have seen a similar example before. The predicate returns a numeric value. According to the rules for determining the predicate truth value, it is compared to the context position. If it is equal to the context position, the predicate truth value is true, returning the item from the sequence on position two.

PillAt Avonmouth, on the Severn Estuary near Pill, the difference between high and low tide can be as much as 40 feet (12.3 metres) – the second highest tidal range in the world. With each rising tide, enormous volumes of water push into the mouth of the river from the Bristol Channel, only to flow out again a few hours later.
The Pill Pilots
The village of Pill was famous for the skill of its pilots, who used their knowledge of the tides and currents of the Bristol Channel to guide ships safely to the mouth of the Avon. But the journey up the river to Bristol was no less arduous. Ships had to be towed upriver on the rising tide and safely moored before the ebb. At low tide ships had to rest on the river bed. The journey for a ship being towed from Pill to Bristol could take a week.
The Pill Hobblers
The cargoes of some larger ships were transferred to smaller craft to make the journey up to Bristol. The big ships were moored at Pill's Hung Road and the Pill Hobblers hauled the smaller boats upriver using the towpath and sometimes horses. The hobblers also towed ships into Bristol with rowboats. Steam tugs eventually took over, but Pill still has its Hobblers who do the same job they have done for centuries. Find out more about the modern day Hobblers here.

Severe ME
Around one in four people with Myalgic Encephalomyelitis (ME), are house bound or bed bound. People with severe ME need help to care for themselves and complete minimal daily tasks (e.g. cleaning teeth). They can experience significant cognitive impairment and may depend on a wheelchair for mobility.
In very rare circumstances, complications from ME for people in severe subgroups has resulted in death. In Australia, Alison Hunter died in 1996, aged 19, from complications arising from ME, which included seizures, paralysis, gastrointestinal paresis and overwhelming infection.
The stories below focus on the challenges and experiences of people with severe ME.

A propane torch is a very versatile tool for many home repair jobs. Used in low-heat applications, a propane torch can help you soften old paint or loosen a rusted bolt. With higher heat, a torch can solder plumbing or electrical connections. Knowing how to use a propane torch properly will ensure that you complete the task at hand effectively while maintaining a safe work environment.
Method 1
Method 1 of 3:
Operating a Propane Torch
Download Article
 1. 1
 Choose the right propane torch for your needs. Most propane torches consist of a small gas tank fitted with a regulator, with or without an electric igniter. If yours doesn't have an igniter, you'll need to use a striker to light the torch.
 - If you need low heat, opt for a propane torch with a flame-spreading tip, which will allow you to diffuse the flame to lower its heat.
 - When using a high heat for repairing chain-link fences and the like, consider using an oxygen-fuel torch. These torches have 2 separate tanks for gas (usually propane or MAPP) and oxygen.[1]
 2. 2
 Wear appropriate safety gear. Before using the propane torch, you should put on a pair of heavy work gloves and safety glasses. It is also best to wear long sleeves and pants. Your propane torch should only ever be used in well ventilated areas. [2]
 - Be cautious of wind when using your torch. It can cause the flame to jump and catch unintended things on fire. Never ignite your torch near flammable material.
 - Avoid clothing that is loose or hangs. Loose or hanging clothing is more likely to accidentally catch on fire when operating a torch.

 3. 3
 Light the propane torch. Hold the torch with the tip facing away from you and open the gas valve. If you have a striker, place it over the torch nozzle and strike it to ignite the gas. If your torch has an electric igniter, pull the trigger to ignite the gas. This may take several tries.[3]
 - Some propane torches have a safety trigger that must be depressed when lighting the gas.
 - If you are using your torch indoors, make sure to open a window for ventilation. If using one outdoors, be cautious of the wind causing the flame to jump to flammable objects.[4]
 4. 4
 Adjust the height of the flame. Once the propane torch is lit, you can adjust the height of the flame by turning the gas valve. For soldering or other high heat applications, a small flame is best. A larger flame works better for low heat applications.[5]
 - The flame will have a bright inner cone and a more diffuse outer cone. The hottest point of the flame is the very tip of the inner cone.
 5. 5
 Place the flame against the material you need to heat. For soldering pipe, place the tip of the inner cone against the joint and hold the torch steady. For loosening rusty bolts, try to focus the flame on the nut only or the surrounding metal. For low heat applications, hold the flame further away from the material and keep the torch in motion.
 - Applying your torch to metal will cause the metal to expand. When loosening bolts, it may be best to heat the surrounding metal to prevent the bolt from expanding.
 6. 6
 Turn off the gas when you are done using the torch. After use, rotate the gas valve until it closes completely. Allow the propane torch to cool down and then store it in a dry location. Listen for running gas to ensure safety.
 - Separate your torch from the fuel cylinder when you finish using it. This will provide less opportunity for accidents.[6]
 - If you hear leaking gas, check the valve and make sure it is completely closed. If you still hear gas, check for leaks in the fashion explained in the section on troubleshooting your torch.

Method 2 of 3:
Soldering Copper Pipe
Download Article
 1. 1
 File rough edges on your pipe if necessary. Use a metal file to take off burrs, rough edges, and loose shavings on your pipe. This is especially important if you have cut the pipe to fit a plumbing project.
 - When the jagged edges of your pipe have been filed down, wipe away any remaining fragments with a clean rag.
 - If you don't have a proper file, substitute fine grain sandpaper, emery cloth, or steel wool to smooth rough edges on your pipe.
 - If your pipe didn't cut cleanly and has jagged edges or burrs, wear work gloves when filing to prevent cuts and slivers.[7]
 2. 2
 Dry the pipe. In most cases, you can do this by tipping the pipe upside down to force the water out one end of the pipe. If this is impossible, use a dry, clean cloth to absorb all water or liquid near where you'll be applying the solder.
 - Water can interfere with the soldering process and create a weak bond in it. Be thorough when drying your pipe.
 3. 3
 Shine the pipe. A shiny pipe will solder more easily than ones that are not. Use a wire brush on the part of your pipe you will be soldering. Brush the pipe until it shines brightly, and do the same to the joint you will be soldering.[8]
 - Use a clean rag on your pipe after shining it to wipe away any dirt or particles that have been loosened when shining.
 4. 4
 Prevent the flow of water in your pipe. Insert a drain plug, available at your local hardware store, into the pipe to prevent the flow of water. Water can remain in the line if the pipe is still attached and run to where you are soldering, negatively impacting the bond.
 - Generally, pipe plugs come with an applicator. Use this applicator to push the plug up the pipe. Dissolve the plug when you are done by briefly applying the torch to the area the plug is.[9]
 5. 5
 Apply flux to your pipe where you will solder. Be sure you're wearing gloves and goggles when doing this. Flux that has not been treated with heat can be harmful in your eyes, mouth, or open cuts.[10] Use the applicator that came with your flux to apply a thin layer of it to the outer surface of the pipe you'll be soldering.
 - If this is your first time soldering pipe, you may apply to much flux initially. Wipe away excess flux with a clean cloth.
 6. 6
 Heat the flux. Light your torch and hold it 2 in (5.1 cm) from the part of the pipe with flux on it. Pass it back and forth over this area for about 10 to 20 seconds. First the flux will become shiny, but then the pipe should darken. When the flux sizzles and smokes slightly, the pipe is ready for solder.
 - Be cautious when handling heated pipe. Touching this could result in accidental burn in the same way touching the flame of your torch would.
 - Keep the flame of your torch set to a moderate or low setting when heating flux. You only need a relatively low temperature to melt it.[11]
 7. 7
 Assemble the pipe components and heat them. Use caution when assembling pipe components so as to not burn yourself on the heated part. Slide the pipe into the fitting until it can go no further. Twist the pipe back and forth in the fitting to spread the flux on the inside of the joint. Then use your torch to reheat the assembled components.
 - Pass the flame of your torch evenly back and forth over the pipe components. Failing to heat these evenly could cause your solder to melt unevenly, allowing water to leak.[12]
 8. 8
 Apply solder to the pipe. Hold your solder to the heated pipe. If the solder runs, your pipe components are sufficiently hot enough to begin soldering. If your components glow or turn a blue color, you've applied too much heat.
 - If you've applied too much heat to your pipe, wait for it to cool completely. When the pipe is cool, try again by repeating this process from the beginning.
 9. 9
 Clean the pipe after soldering. While the pipe is still warm but the solder solid, brush another thin layer of flux on the solder. After that, use a clean cloth to wipe the soldered joint clean. Do not try to cool the joint rapidly. Doing so could cause damage to it.[13]
 - Avoid tightening the fixture or moving the joint around until the solder has completely cooled. The solder will remain soft until it is cool.

Troubleshooting Your Torch
Download Article
 1. 1
 Avoid tipping the torch more than 60° from upright. Tipping your torch in this fashion can cause the torch to flare. This can be especially dangerous on windy days. The wind could cause the flame to jump to the surrounding area and start a fire.[14]
 2. 2
 Recognize the effect of temperature on your torch flame. If you use your torch in cold weather and if your torch is not pressure regulated, you may notice that the flame is smaller than usual. Cold temperatures reduce the amount of pressure in the tank, resulting in a smaller flame.
 - Keep your tank in a warm, indoor area and use it quickly and efficiently when out in the cold to maintain a suitable flame.[15]
 - Using a pressure regulated torch will also prevent a small flame due to temperature.
 3. 3
 Check your torch for leaks. If you hear a hissing noise of gas escaping your torch even while the valve is

Fun things to do in and around Pueblo
This nationally designated scenic byway climbs from Pueblo's high plains, up through Hardscrabble Canyon into the Wet Mountain Valley, and descends back through the foothills onto the high plains at Colorado City. Along the byway, visitors can stop in Westcliffe, a quaint mountain town, with great shopping, wildflower meadows, intimate views of the Sangre de Cristo mountains, and plenty of summer festivals. Check out Additional Information: FrontierPathways.org Frontier Pathways Itinerary Frontier Pathways Guide Tour Colorado
Just one hour east of Pueblo sits Bent's Old Fort National Historic Site, a reconstructed 1840's adobe fur trading post on the mountain branch of the Santa Fe Trail where traders, trappers, travelers and Plains Indian tribes came together in peaceful terms for trade. Today, living historians recreate the sights, sounds and smells of the past with guided tours, demonstrations, and special events.
Once considered Pueblo's Red-Light District, this historically significant shopping area boasts 83 buildings on the National Historic Register. With the Historic Union Depot on one end and the Historic Riverwalk on the other, this District is perfect for strolling, gallery hopping, shopping, or eating ice cream and cupcakes.
In honor of Pueblo's four Congressional Medal of Honor Recipients, the Pueblo Convention Center built the "Home of Heroes" Congressional Medal of Honor Memorial Plaza. The four larger-than-life, sculpted and bronze statues flank the main entry and welcome you to the Pueblo Convention Center. The Medal of Honor is the highest military award that can be bestowed upon a member of the United States Armed Forces; Teddy Roosevelt lobbied for one but never received it, and General George Patton said "I'd sell my immortal soul for that Medal."
The building at this location is the only remaining firehouse in Pueblo that housed horse-drawn fire equipment and one of two remaining that has the famous brass pole still intact. It was "home" to the valiant men who served with the distinguished Hose Company No. 3. The building was erected in 1881 and the last fire alarm was sounded on March 9, 1979. The building continues its fire-related service to the community through the backing of a fire museum. A wealth of information and pictures, as well as antique fire engines, hose carts and other memorabilia are on display.
Just a short drive west of Pueblo, experience the natural beauty of the famous Royal Gorge each year aboard Colorado's finest scenic railroad. Enjoy the comfort and charm of carefully restored railroad cars. Travel in glass-topped vista dome cars, have a gourmet lunch or dinner and even partake in a murder mystery on the train. This is a fun way to enjoy the charm of classic train travel and the dramatic views of the Royal Gorge.
Pueblo is the hometown of four Congressional Medal of Honor recipients. This memorial honors each of these men with a life-size statue, and includes the engraved names of 3,400 other recipients. Visitors can learn the stories behind each name with a computer database and display inside the Convention Center. The database also features the stories of local veterans who are commemorated on the newly built Veterans Bridge, which sits adjacent to the Convention Center parking lot.


wiki:ReplacingGMPNotes/TheCurrentGMPImplementation
Version 10 (modified by p_tanski, 7 years ago) (diff)
add clarification for GMP function allocation from GHC heap
The Current GMP Implementation
Esa Ilari Vuokko, who at one time attempted to replace GMP with LibTomMath, posted several messages with good notes on the current implementation. Much of what is on this page is derived from those notes. See, Replacement for GMP(3) and Replacement for GMP(4).
GMP and the Storage Manager
The most insidious and unique feature of the GHC implementation with GMP is memory management. GHC uses the special memory functions in GMP ( mp_set_memory_functions( (*alloc)(), (*realloc)(), (*dealloc)() ) to let GMP use GHC's own garbage collector. The memory functions are implemented in rts/sm/Storage.c as:
 static void* stgAllocForGMP (size_t size_in_bytes);
 static void stgDeallocForGMP (void *ptr STG_UNUSED,
 size_t size STG_UNUSED);
 static void* stgReallocForGMP (void *ptr,
 size_t old_size,
 size_t new_size);
These special allocation functions bring most GMP memory usage into the GHC heap but do not seem that efficient otherwise. (I could be wrong --PDT.) Allocation uses the internal allocate() interface, so no garbage collection is performed during a GMP operation. Note that GMP operations may use these functions to allocate more memory themselves, after being called from Haskell code. The memory allocated is a simple array of words (W_), rounded up to a whole number.
Special Functions
GHC adds its own functions for string conversion, least common multiple (lcm) and conversion to and from floating point (floats and doubles). In particular, the GHC designers decided to perform their own operations for encoding a GMP number (really, the array of mp_limb_t) to floating point numbers (floats or doubles). GMP provides functions for some of these operations:
Operation GMP function Notes
convert to double mpz_get_d() rounds toward zero, avoids overflow
convert to double
return exponent separately
mpz_get_d_2exp() rounds toward zero, avoids overflow
convert to float mpz_get_f()
convert to string
supports bases from 2 to 36
mpz_get_str() more efficient than Haskell version,
with PackedString, no conversion to Haskell string necessary
conversion from string mpz_inp_str() more efficient than Haskell version,
with PackedString, input string efficiently convertable to a c_str
(it is already an array of chars)
The real problem (no pun intended) is conversion to doubles and floats. The __encodeDouble function, in rts/StgPrimFloat.c, may overflow:
StgDouble
__encodeDouble (I_ size, StgByteArray ba, I_ e) /* result = s * 2^e */
{
 StgDouble r;
 const mp_limb_t *const arr = (const mp_limb_t *)ba;
 I_ i;
 /* Convert MP_INT to a double; knows a lot about internal rep! */
 for(r = 0.0, i = __abs(size)-1; i >= 0; i--)
 r = (r * GMP_BASE) + arr[i];
 /* Now raise to the exponent */
 if ( r != 0.0 ) /* Lennart suggests this avoids a bug in MIPS's ldexp */
 r = ldexp(r, e);
 /* sign is encoded in the size */
 if (size < 0)
 r = -r;
 return r;
}
If the problem section hurt your eyes, here is some more pain to drive the point home:
 /* __abs(size) is the size of the array --PDT */
 for(r = 0.0, i = __abs(size)-1; i >= 0; i--)
 r = (r * GMP_BASE) + arr[i];
Note the problems:
 - GMP numbers may be very large, much greater than the maximum value for a float (addition and multiplication operations may overflow);
 - there is no specification of rounding mode--this operation relies on whatever hardware rounding may take effect; and,
 - certain floating point hardware exceptions (traps) for overflow or underflow may be triggered (though this is not generally the case; note: on x86 machines floating point exceptions may not be triggered but the resulting float may denormalized).
Nowhere in this function is there a check for whether the GMP number (the const mp_limb_t *arr) may be greater than the size of a double and either warn the user (possibly with an ArithException or round the resulting double toward zero.
Compare the problem section in __encodeDouble to the exponent check in the internal GMP function, mpn_get_d, that avoids overflow by comparing the relative magnitude of the GMP number with the maximum magnitude of the double:
 /* note: exp is a long int, given as an argument to min_get_d as 0L --PDT */
 /* Adjust exp to a radix point just above {ptr,size}, guarding against
 overflow. After this exp can of course be reduced to anywhere within
 the {ptr,size} region without underflow. */
 if (UNLIKELY ((unsigned long) (GMP_NUMB_BITS * size)
 > (unsigned long) (LONG_MAX - exp)))
 {
 if (_GMP_IEEE_FLOATS)
 goto ieee_infinity;
 /* generic */
 exp = LONG_MAX;
 }
 else
 {
 exp += GMP_NUMB_BITS * size;
 }
(If you want to see the full mpn_get_d function, it is in the file [toplevel gmp source]/mpn/generic/get_d.c .)
There is no check in the Haskell code using __encodeFloat or __encodeDouble, in libraries/base/GHC/Float.lhs. For example, the encodeFloat Haskell function under class RealFloat uses __encodeDouble directly:
encodeFloat (J# s# d#) e = encodeDouble# s# d# e
This is not the case with the safer fromRat function which ensures the Integer falls in the range of the mantissa (see the source code).
A replacement library for GMP might use the GMP strategies of including a special bitwise conversion (with appropriate masks) and a hardware-based version. An unconventional solution might perform the rounding manually (but with relatively portable predictability) using interval arithmetic.
As for printing GMP numbers, libraries/base/GHC/Num.lhs defines a special internal function jtos to handle showsPrec and showList for Integer as an instance of the class Show. The jtos function uses the primitive GMP-based function quotRemInteger and performs many conversions from Integer to Int. This is not as efficient as the internal GMP functions, especially for large numbers, because each conversion allocates extra storage for GMP as noted in Replacing GMP -- Optimisation Opportunities.

I got the error
cannot implicity convert type 'System.Linq.IQueryable' to 'EntityNetimoveis.San_Imovel' An Explicit conversion exists (are you missing a cast?)
This occurs when I try the following code
EntityNetimoveis.San2011Entities db = new EntityNetimoveis.San2011Entities();
EntityNetimoveis.San_Imovel im = db.San_Imovel.Where(a => a.Credenciada_Id == 10);
What type of conversion I have to do?

The type of im is an IQueryable because you are running a where query and there might be more than one result. If you want the first result matching your query you should use.FirstOrDefault(). Try changing you code as:
EntityNetimoveis.San_Imovel im = db.San_Imovel.FirstOrDefault(a => a.Credenciada_Id == 10);
If you want to return more than one entity and process them, lets say using a foreach loop, then you need to change the type of the return value to IEnumerable. See the following example:
IEnumerable ims = db.San_Imovel.Where(a => a.Credenciada_Id == 10);
The you can use the following:
foreach(var im in ims) {
 // your code goes here

But I need more than one result, can be millions of registers that has a.Credenciada_Id == 10. I need to save this in Entity.San_Imovel and then I need to do a ForEach. How can I perform this? – Lucas_Santos Aug 24 '12 at 13:57

If the lambda can return more than one record:
var imList = db.San_Imovel.Where(a => a.Credenciada_Id == 10).ToList();

I have to return all register in my database that has the column Credenciada_Id equals 10. Can be millions of registers, so I need to put in San_Imovel all these registers, and then I'll do a Foreach – Lucas_Santos Aug 24 '12 at 13:55
Is SingleOrDefault supported in Linq-To-Enitities? – Tim Schmelter Aug 24 '12 at 13:55

Exists, but I need to return more then one result. – Lucas_Santos Aug 24 '12 at 13:58
_USER_ The expression Massimiliano is using will return a List. Theoretically, you could leave off the.ToList part and you'd have a IQueryable, which implements IEnumerable. Both methods will give you more than one result if more than one result exist. – villecoder Aug 24 '12 at 14:00

This talk will examine the deep and often troubling change of Central European cities after the fall of state socialism by using Prague as its case. It will look specifically at following transformations: a collapse of traditional Prague-based manufacturing and relocation of labor force, the lack of socially affordable housing, the massive increase in automobile transport to the detriment of public transport, the radical change in the patterns of consumption and leisure activities, and the change in discourse about the nature of the city and its future. In the new neoliberal spirit, the city planning, as any planning, was seen as part of the suspect heritage of state socialist planned economy. The lecture will attempt to look at these and other changes as part of long term transformation that preceded the actual fall of state socialism. It also will attempt to situate those within broader trends in European urban development since the 1970s, thus revisiting the established academic debate of what is actually socialist about socialist cities.

Magic, spirits & herbs
Before the Egyptian and Sumerian civilisations, there were no written records, so what we know about diseases and their treatment during prehistoric times has been gleaned either from archaeological evidence, or from interviews with aboriginals whose lifestyles have not changed for thousands of years.
The land was sparsely populated by nomadic hunter-gatherers occupying seasonal camps in caves or rock shelters where food was plentiful. The average lifespan was 25 to 40 years. It was generally believed that all natural things were controlled by spirits, and that illness was the result of evil spirits, sent either as punishment from the gods or as magic from an enemy.
The "cure" was to drive out the evil spirits; this involved witch doctors or healers (shamans) using ceremonial magic.
Archaeological evidence
Study of human remains suggests that the common diseases in prehistoric times were:
 - osteoarthritis (from heavy lifting and carrying)
 - microfractures of the spine & spondylosis
 - hyperextension and torque injuries of the lower back, often associated with carrying latte stones
 - infections and their complications
 - rickets
Mummified bodies have revealed ingested plants and seeds from the Palaeolithic era (60,000 years ago) onwards. These include yarrow (as an astringent to stop bleeding), mallow (as a laxative), rosemary, digitalis, morphine (extracted from seeds as a painkiller), snakeroot (as a mild sedative) and birch polypore fungus (as a laxative).
Some Stone Age skulls have been found with holes cut into them and, in some, there is evidence of the bone "growing back", implying that the individual survived the procedure. This practice, known as trepanning (pictured upper right), has been in use for thousands of years to treat epilepsy, headaches, mental illness and assumed demonic possession, although it may also have been performed as part of a ritual.
Archaeological evidence has been found of geophagy (eating earths & clays). This may have been prompted by watching animals eat earth, either to get essential minerals or when they are unwell.
Evidence from aboriginals
Some aboriginals still practise lifestyles that have not changed for thousands of years. In the late 19th century, a number of interviews were carried out with aboriginal groups in an attempt to understand some prehistoric relics being discovered at that time.
Cave paintings can provide information about the lifestyle of prehistoric nomads. A prime example is the Grottes des Trois-Frères in southwestern France where the cave art dates back at least 13,000 years. There are numerous engravings in the three caves, but The Sorcerer (pictured middle right) is of particular interest in that it may represent a healer with a deer-mask, worn to frighten away the demons causing illness (or simply to impress the patient!).
Some present-day aboriginals still treat fractures using wet clay which then hardens to give support to the limb in the same way as a plaster cast does. Hunter-gatherers were, of course, prone to trauma and fractures because their lifestyle involved significant personal risk whilst hunting and killing large animals.
Prehistoric urology
Although we have no archaeological evidence of urological disease, prehistoric cave paintings of the penis have been found dating back to the Upper Palaeolithic period (12,000 to 40,000 BC). They suggest an awareness of erection, copulation, ejaculation (pictured lower right) and orgasm.
Indirect evidence exists that foreskin retraction and/or circumcision was also performed, and a detailed analysis suggests that other decorative rituals (tattooing, piercing, and scarification of the penis) took place, possibly as group recognition strategies, especially during the Upper Magdalenian period (11,000 to 12,700 BC).

FizzBuzzBongo-feature-2
This is the second in a series of 'how-to' articles on creating an interactive Alexa Skill. The skill is called 'Fizz Buzz Bongo' and is available in the Alexa Skills Store. It's a variation on the classic 'Fizz Buzz' programmer test, but converted into a game. The first articles detail explain the Java code and how to build it, then how to deploy it to AWS using Terraform and finally how to register the Alexa Skill in the Amazon Developer Console.
Full source code is available at _URL_ Click the links below to see parts 1 and 3:
Prerequisites
This article is a follow up article to the first article "Developing an Alexa Skill: Part 1, Creating the Java Lambda". In that post I describe everything you need in order to checkout the source code and get it to build into a JAR file containing everything it need to run as an AWS Lambda.
The entry point for this post is that you have the source code on your machine, and you've run a succesfull build using Maven, which has produced the following file in your /target directory
alexa-fizzbuzz-demo-0.0.1-SNAPSHOT-jar-with-dependencies.jar
(Note – the actual version number may be different at the time you check the code out).
Deploying to AWS UsingTerraform
So the next step is to get that file uploaded to AWS. However, we also need a DynamoDB table and set up all the permissions correctly. While it's possible to do this by hand purely using the AWS console, it's better practice to automate this in code.
Building your service is known as "Infrastructure as Code" (IaC) like this allows you to document your infrastructure and recreate it easily if you need to. This is especially important as it grows and becomes more complex. Doing anything by hand is time consuming and error prone, and it can be easy to forget what you've done down the line. Far better to spend a bit more time up front automating it – and then everything downstream becomes easier (and more robust).
In this initial demo I've chosen Terraform – a popular and feature-rich cross-cloud solution from HashiCorp. In a later article I'll do the same thing using native AWS CloudFormation. In order to get started – you'll need the AWS CLI and Terraform installing on your machine.
Download the AWS Command Line Interface (CLI)
If you haven't done so already – download and install the AWS command line tools from _URL_
Configure your AWS Credentials
There are a number of ways to configure the CLI with your AWS credentials – credentials file, config file, environment variables, etc. I won't try and cover them all here – check out the AWS CLI documentation for details.
Terraform will pick up your credentials from the AWS CLI.
Alternatively – you can supply them directly in the terraform template file if that's easier. Just edit the main.tf file at:
/repo-install-location/alexa-fizzbuzz-demo/IaC/terraform/fizzbuzz/main.tf
Uncomment the 'provider "aws"' section at the top, and replace the placeholders with your AWS credentials. These are available from the AWS IAM console.
provider "aws" {
 access_key = "INPUT_HERE"
 secret_key = "INPUT_HERE"
 region = "INPUT_HERE - e.g. eu-west-2"
}
The downside to adding them here, is that if you commit it all your key information is in source control.
Note: If you're automating your infrastructure provisioning, it's good practice to create a specific IAM user/role to execute the provisioning under (e.g. a 'Builder' user), rather than using your root account. This way to can tie down access to just what it needs to run to provide a finer degree of control/security.
Download Terraform
Download zip from _URL_. Extract it somewhere on your machine and then add it to your executable PATH
$ export PATH=$PATH:~/your-install-location/terraform
If you want this to be persisted between terminal sessions, you can add to ~/.bash_profile (or whichever startup file you use). Note – I'm developing on a Mac, so these instructions will be slightly different for a Windows machine.
The Terraform Templates
The main terraform template is located at /IaC/terraform/fizzbuzz/main.tf. This file calls a module 's3-lambda-ddb/main.tf' (I need to remove the s3 part, as it no longer provisions any S3 resources – that was while I was testing). As you can see – this file references the build artefact. If the version in the pom.xml file has changed – the build artefact name here will need updating accordingly.
module "fizzbuzz" {
 source = "../modules/s3-lambda-ddb"
 fizzbuzz_lambda_function_name = "alexa-fizzbuzzbongo-skill"
 fizzbuzz_lambda_object_key = "alexa-fizzbuzzbongo-0.0.1-jar-with-dependencies.jar"
 dynamoDbTable = "FizzBuzzBongoUserData"
}
The module file handles the actual creation of the lambda (including the upload of the JAR file) and the the DynamoDB table. It also sets the Alexa trigger for the lambda and provisions all the permissions it needs.
There are some settings here that can be tweaked – namely the lambda memory allocation and the DynamoDB read and write capacity. It all depends on how much the skill gets used 'in the wild'.I suspect I may increase the lambda memory (to improve cold start times) and reduce the DynamoDB read/write capacities (as I don't think it will get used that much). However – following the principle of not optimitising prematurely – I'll wait and see what real world usage is first. I'll probably cover tweaking these in another article.

Where it all began
MAF began with some World War II pilots who had a vision to help those in need. The idea was to use planes positively to spread the peace of God – rather than negatively to spread the conflict of man. After the war, Murray Kendon, Stuart King and Jack Hemmings worked with the Mildmay Movement to raise the funds required to realise their vision.
In 1948, the first survey flight of Africa was completed and Sudan identified as a country with need of an aircraft to help further the gospel. In 1950, the first MAF base started in Akobo, Sudan. At the same time, similarly minded Christian pilots started missionary organisations in the US and Australia, eventually also becoming known as MAF. Able to provide medevacs to missionaries in remote areas and help reach the isolated communities, the visions of those early pioneers became a reality. Within 15 years, there were operational bases opened in Sudan, Mexico, Papua New Guinea, Indonesia, Ecuador, Kenya and Ethiopia.
What started off as the dream of a few Christian air force pilots is now a global movement with around 123 aircraft serving in over 25 countries worldwide. Tens of thousands of remote communities now have access to healthcare, education, community development, disaster relief and the Good News of Jesus Christ.
A lot has happened over the 70 years since MAF was formed, but through the change, through all the developments in technology and aviation practices, the heart of MAF has stayed the same: to see isolated people changed by the love of Christ through serving together to bring help, hope and healing through aviation.

|The SEQDESIGN Procedure|
|Summary of Methods in Group Sequential Designs|
There are three different types of methods available in the SEQDESIGN procedure: fixed boundary shape methods for specified boundary shape, Whitehead methods for boundaries from continuous monitoring, and error spending methods for specified error spending at each stage.
The fixed boundary shape methods include unified family methods and Haybittle-Peto methods. The unified family methods include Pocock, O'Brien-Fleming, power family, and triangular methods.
Pocock derives the constant boundary on the standardized scale to demonstrate the sequential design while maintaining the overall and levels (Pocock 1977). The resulting boundary tends to stop the trials early with a larger -value. This boundary is commonly called a Pocock boundary, but Pocock himself does not advocate these boundary values for stopping a trial early to reject the null hypothesis, because large -values might not be persuasive enough (Pocock and White 1999). Also, the nominal -value at the final stage is much smaller than the overall -value of the design. That is, the trial might stop at the final stage with a small nominal -value, but the test is not rejected, which might not be easy to justify.
O'Brien-Fleming boundary values are inversely proportional to the square root of information levels on the standardized scale (O'Brien and Fleming 1979). The O'Brien-Fleming boundary is conservative in the early stages and tends to stop the trials early only with a small -value. But the nominal value at the final stage is close to the overall -value of the design.
The power family method (Wang and Tsiatis 1987; Emerson and Fleming 1989; Pampallona and Tsiatis 1994) generalizes the Pocock and O'Brien-Fleming methods with a power parameter to allow continuous movement between the Pocock and O'Brien-Fleming methods. The power parameter is for the Pocock method and for the O'Brien-Fleming method.
The unified family triangular method (Kittelson and Emerson 1999) contains straight-line boundaries on the score scale. For a one-sided trial with early stopping either to reject and to accept the null hypothesis, the method produces a triangular continuation region. The boundary shape is specified with the slope parameter.
The unified family method (Kittelson and Emerson 1999) extends power family methods to incorporate the triangular method, which contains straight-line boundaries on the score scale.
The Haybittle-Peto method (Haybittle 1971; Peto et al. 1976) uses a value of for the critical values in interim stages and derives the critical value at the final stage. With this method, the final-stage critical value is close to the original design without interim monitoring. The SEQDESIGN procedure extends this method further to allow for different or nominal -values for the boundaries.
Whitehead methods (Whitehead and Stratton 1983; Whitehead 1997, 2001) derive the boundary values by adapting the continuous monitoring tests to the discrete monitoring of group sequential tests. With early stopping to reject or accept the null hypothesis in a one-sided test, the derived continuation region has a triangular shape on the score-scaled boundaries. Only elementary calculations are needed to derive the boundary values in Whitehead's triangular methods. The resulting Type I error probability and power are extremely close but differ slightly from the specified values due to the approximations used in deriving the tests (Jennison and Turnbull 2000, p. 106). The SEQDESIGN procedure provides the BOUNDARYKEY= option to adjust the boundary value at the final stage for the exact Type I or Type II error probability levels.
The error spending method uses the specified and errors to be used at each stage of the design to derive the boundary values.
The error spending function method uses the error spending function to compute the and errors to be used at each stage of the design and then to derive the boundary values for these errors. The following four error spending functions are available in the SEQDESIGN procedure:
The Pocock-type error spending function (Lan and DeMets 1983) produces boundaries similar to those produced with Pocock's method.
The O'Brien-Fleming-type error spending function (Lan and DeMets 1983) produces boundaries similar to those produced with the O'Brien-Fleming method.
The gamma error spending function (Hwang, Shih, and DeCani 1990) specifies a gamma cumulative error spending function indexed by the gamma parameter. The boundaries created with are similar to the boundaries from the Pocock method, and the boundaries created with or are similar to the boundaries from the O'Brien-Fleming method.
The power error spending function (Jennison and Turnbull 2000, p. 148) specifies a power cumulative error spending function indexed by the power parameter. The boundaries created with are similar to the boundaries from the Pocock method, and the boundaries created with are similar to the boundaries from the O'Brien-Fleming method.

Learning Outcomes & Learning Demonstration Statements
Since you will be given credit for the learning you have acquired through your experience, you will need to be able to measure this learning against a course or set of courses that UFV offers. How does this work?
Every course outline at UFV contains a section called Learning Outcomes. A learning outcome is a specific and measureable statement written to describe knowledge and skills that students will have achieved at the end of a course or program. It is the way we as teachers can be sure our students have learned what we intended they would learn in our course.
Learning Demonstration Statements
You have now looked at the learning outcomes for a course or program and have said to yourself, "I can do that!" Learning demonstration statements can help organize your learning in your request to be approved to pursue PLAR and to describe physical or electronic evidene of learning that relates to course or program learning outcomes.
You can see Tips on Learning Statements for more information.
Please use this list of verbs to develop learning statements that best reflect you skills, knowledge and abilities.
Use the program index to see an initial list of potential PLAR courses (as they are courses required in your program of study).

The paper presents the magnetic field modeling for magnetic particle imaging (MPI). The custom static magnetic field solver which enables fast calculation of three dimensional magnetic field distribution was elaborated. The regular square grid is applied in this solver. A setup of coils for MPI was designed. The selection field and the drive fields are generated by three pairs of coils. The magnetic field was calculated using the elaborated custom solver and using the COMSOL commercial FEM software. The comparison of results is presented. The elaborated solver can be used in numerical simulation of spatial encoding methods for magnetic particle imaging.

Microfluidic devices for the preparation of blood plasma samples in circulating nucleic acid based medical applications
MetadataShow full item record
Separation of plasma from blood is the first sample processing step in numerous medical diagnostics, including a novel class of tests that target cell-free nucleic acids (cfNAs), such as the non-invasive prenatal tests (NIPT). Conventionally, blood plasma separation (BPS) is achieved by centrifugation and followed by a number of labour-intensive bench-top procedures. Thus, developing an alternative BPS technology based on microfluidics would open the way for integration of the entire sample processing route in a single automated device, increasing sample processing throughput and robustness. Rapid extraction of cfNAs would also improve their stability facilitating further analysis. Plasma samples in cfNA-based diagnostics need to meet strict quality criteria. Currently, all the industrial and academic operators require over 1 ml of plasma for the cfNA-based tests. However, microfluidic systems typically enable miniaturisation and smaller footprints via the extraction of much lower volumes (0.1-100 µl). Thus, combining high sample quality and large output volume was the main challenge for the development of a suitable microfluidic solution here. This thesis presents a novel coupling of hydrodynamic and sedimentation-based microfluidic cell removal in a single "hybrid" BPS system. The device output was characterised in relation to several parameters: (1) blood dilution, (2) chip geometry, (3) extraction yield, (4) cell removal, (5) haemolysis and (6) cell-free DNA (cfDNA) concentration. The quality of separated plasma was shown to be compatible with advanced cfDNA analysis methods used in NIPT (digital PCR and sequencing). Its fetal and maternal cfDNA content was demonstrated to be the same as in the control samples obtained via NIPT gold standard protocol. The design of the BPS system, most importantly its hydrodynamic module, enables the use of cost-effective mass production methods as well as the coupling of additional sample processing modules. The industrialisation of the prototype, together with the validation of its use in cfDNA workflows, will enable the future implementation of the developed system as a component of an integrated sample processing tool in cfNA-based diagnostics.

In a previous post, I compared the features and capabilities of Samba winbind and SSSD. In this post, I will focus on formulating a set of criteria for how to choose between SSSD and winbind. In general, my recommendation is to choose SSSD... but there are some notable exceptions.
 - The first exception is if you have a deployment of Linux systems that are already leveraging Samba winbind for integration purposes. While, in this scenario, it might be cost prohibitive to switch to SSSD – you might eventually consider switching off Samba winbind due to changing / shifting requirements. In such cases we recommend engaging with a Red Hat representative to receive an overview of the latest integration capabilities (...as SSSD and IdM technologies are actively being developed – each incorporating additional features and capabilities over time).
 - The second exception is if you use Active Directory (AD) with the NTLM protocol enabled and fallback to NTLM authentication is still a requirement for your environment. In this scenario, winbind is a better choice as SSSD does not support the NTLM protocol.
 - The third exception is if SSSD fails to support a specific feature that you require (i.e. one that winbind supports); indeed, not all use cases are addressed in the same way between SSSD and winbind. For example, SSSD does not support cross forest AD trusts when connected directly to AD (and winbind does). However, in this example, the work around is to use IdM. Being connected to IdM, SSSD recognizes other AD forests that are in trust relationships with the IdM domain. Irrespective, if there are specific features that you require, ones
 that SSSD fails to support, we'd be very interested to hear more about your needs.
Is Samba winbind
deprecated? The answer is most certainly: no. The reality is that there's currently a shift in emphasis from one technology to another and, as always, Red Hat is committed to supporting features and components that are (already) widely adopted and deployed while also making sure we provide support for new deployments to select the best available option. Have you shifted from Samba winbind to SSSD? If not, what's holding you back? Let me know what you think in the comments section below.

Converter rated power
I am new to HOMER and currently I am simulating Wind/PV/Grid system and comparing it to the actual system that has been built. I have a couple of questions to ask:
1. I noticed that the the wind turbine never reaches its rated power of 500 kW. I am wondering why this happens? In real condition, the wind turbine reaches its rated power at least 10% of the time.
2. Also, I've put 0-1750 KW (as the actual system size) in the search space for solar converter but in the optimisation results, HOMER always suggests 1400 KW converter. Is there any way to change this? I am trying to get simulation results as close as possible to the actual system.
1) a) The wind turbine output depends on the available wind resource and the wind power curve. Make sure, in the power curve, you have defined the wind speed for the rated power. You can find the power curve in the wind turbine design section.
b) Make sure the wind resource has the wind speed that corresponds to rated power.
2) Since you have mentioned a range of sizes (0-1750 kW) for the converter, HOMER chooses the optimal size required as per the PV output produced. If you want a fixed converter size(s), instead of mentioning the range in HOMER optimizer, you can mention specific sizes in the search space. For example, mention 0,500,1000, 1500,1750 in the search space to consider all these sizes. Hope this helps.
Thank you for your suggestions. I've put 1750 Kw in the converter search space and it worked.
I've also updated the wind turbine power curve and have made sure the wind speed in the wind resources exceed the wind speed corresponding to the rated power. However the simulation results were still the same i.e. it never reaches the turbine rated power. It reaches its rated power only when the turbine losses are zero, which is of course impossible. Do you have another suggestion I could try?
I have looked at the windspeed data and it seems some of it is high enough to generate the rated power even after accounting for losses. Here are the HOMER file and the actual wind speed data. FYI, there are two wind turbine Enercon E-48 (500 kW) and 3 Vestas V-52 (850 kW, total 2.55 MW) which all never reach their rated power. I hope you can give me advice on this. Thank you very much.
(wind speed data)
The rated capacity of the wind turbines are 800 kW and 850 kW. However high the wind speeds maybe, under ideal conditions ('0' loss factor), the maximum power that the turbines can produce are 800 and 850 kW. You have mentioned about 9.63% as turbine losses. So the maximum output of the turbines will definitely be lesser than the rated output. Getting rated output from the turbines is an ideal situation.
