Readers ask: How To Slow Cook Beans?
How long do you cook beans in the crockpot on low?
Cook on low for 6 to 8 hours: Cover the pot and cook on low for 6 to 8 hours. If this is your first time cooking beans or you're cooking an unfamiliar kind of bean, begin checking the beans after 5 hours and then every 30 minutes until they are cooked to your liking. Beans generally finish cooking in 6 to 8 hours.
How do I cook beans in 30 minutes?
What do I do if my beans are too hard?
Beans that have been stored for over 12 months or in unfavorable conditions may never soften. Hard water may also cause hard beans. If the cooked beans still seem tough, add a 1/4 teaspoon sodium bicarbonate (baking soda) for each pound of beans to increase tenderness.
Do you have to soak black beans before slow cooker?
Black beans, as you may remember from this Black Bean Soup post, never need to be (and in fact maybe shouldn't be) soaked, regardless of how you cook them: slow cooker, Dutch oven, pressure cooker. Add aromatics, such as an onion, garlic, a bay leaf, all of which will impart the beans with good flavor.
Is it safe to cook beans in slow cooker?
Do Not Cook Dry Beans in Your Slow Cooker It's low and slow, cook -it-all-day technique makes it a perfect vessel for turning tough ingredients into tender deliciousness. But research now suggests that one tough ingredient shouldn't be cooked in the slow cooker at all — beans.

Can I cook dried beans in a slow cooker?
Put 2 cups dried beans into the slow cooker crock and soak overnight in cold water, enough to cover by several inches. Turn cooker to HIGH and cook beans until they're tender and cooked through, about 3-4 hours for soaked beans. (You can also cook the soaked beans on low, which would take about twice as long.)
What to put in beans to prevent gas?
Method 1: Baking soda To cut down on the gassy properties, you can add a little baking soda to your recipe. The baking soda helps break down some of the beans ' natural gas – making sugars.
Should beans be cooked covered or uncovered?
Your beans will be creamy. When we tested both methods, we found the beans with the lid cooked about 15 minutes faster, but the flavor of the beans cooked with the lid off was much better. This is because the liquid reduced more, creating a more flavorful bean broth that coated the beans. Takeaway: Leave the lid off.
Does putting a potato in beans reduce gas?
She put in a whole potato in the pot as well while boiling them supposedly for the purpose of "absorbing" the gas from the beans. The result is that the beans are supposed to make you less gassy but if you eat the potato you'll get super gassy.
Why are my beans still hard after cooking?
The main reason for beans that are still hard after cooking is the quality of the beans. Drying beans preserves them for a long time, but not forever. And make sure to cover them with plenty of water, as beans above the level of the water will take longer to get soft. Even in a pressure cooker.

Why won't my beans get soft?
2 Answers. There are three primary reasons why dried beans do not soften despite extensive cooking time: 1) they are old; 2) hard water; or 3) the presence of an acid. If you don't think your beans are old, then perhaps your water is the problem. Beans cooked in hard water will never soften properly.
How do you make beans soft quickly?
Quick Soak. This is the fastest method. In a large pot, add 6 cups of water for each pound (2 cups) of dry beans. Heat to boiling; boil for 2–3 minutes. Remove from heat, cover and soak for at least 1 hour.
Are black beans toxic?
All legumes, including black beans, contain a compound called phytohemagglutinin, which can be toxic in high amounts. However, the amount of phytohemagglutinin in black beans is typically much lower than the levels in kidney beans, and reports of toxicity have not been linked to this type of bean.
How many cups is 1 lb of black beans?
1 pound dry beans = about 2 cups.
Does slow cooking beans remove lectins?
Cooking with wet, high-heat methods like boiling, stewing, or soaking can deactivate most lectins. However, undercooked or raw beans simmered at low heat or cooked in a slow cooker will not remove all lectins because the heat is not high enough to help break down the enzymes.

The trivial ring is the terminal object in Ring. It is both terminal and initial (hence a zero object) in the category of nonunital rings, but it is not initial in itself (defined as the category of unital rings and unital ring homomorphisms).

Modifying Makefile Entries
The following procedure describes how to add and delete databases from the Makefile.
How to Modify the Makefile to Use Specific Databases
 1. Become superuser or assume an equivalent role.
 Roles contain authorizations and privileged commands. For more information about roles, see Chapter 9, Using Role-Based Access Control (Tasks), in System Administration Guide: Security Services.
 2. Modify the line that starts with the word all by adding the name(s) of the database you want to add:
 all: passwd group hosts ethers networks rpc services protocols \
 netgroup bootparams aliases netid netmasks \
 audit_user auth_attr exec_attr prof_attr \
 auto_direct auto_home auto_direct.time auto_home.time
 The order of the entries is not relevant, but the blank space at the beginning of the continuation lines must be a Tab, not spaces.
 3. Add the following lines at the end of the Makefile:
 auto_direct: auto_direct.time
 auto_home: auto_home.time
 4. Add an entry for auto_direct.time in the middle of the file.
 auto_direct.time: $(DIR)/auto_direct
 @(while read L; do echo $$L; done < $(DIR)/auto_direct
 $(CHKPIPE)) | \ (sed -e "/^#/d" -e "s/#.*$$//" -e "/^ *$$/d"
 $(CHKPIPE)) | \ $(MAKEDBM) - $(YPDBDIR)/$(DOM)/auto_direct;
 @touch auto_direct.time;
 @echo "updated auto_direct";
 @if [ ! $(NOPUSH) ]; then $(YPPUSH) auto_direct; fi
 @if [ ! $(NOPUSH) ]; then echo "pushed auto_direct"; fi
 where
 - CHKPIPE makes certain that the operations to the left of the pipe (|) are successfully completed before piping the results to next commands. If the operations to the left of the pipe do not successfully complete, the process is terminated with a NIS make terminated message.
 - NOPUSH prevents the makefile from calling yppush to transfer the new map to the slave servers. If NOPUSH is not set, the push is done automatically.
 The while loop at the beginning is designed to eliminate any backslash-extended lines in the input file. The sed script eliminates comment and empty lines.
 The same procedure should be followed for all other automounter maps, such as auto_home, or any other nondefault maps.
 5. Run make.
 # make mapname
 Where mapname is the name of the map you want to make.
How to Modify the Makefile to Delete Databases
If you do not want the Makefile to produce maps for a specific database, edit the Makefile as follows.
 1. Delete the name of the database from the all rule.
 2. Delete or comment out the database rule for the database you want to delete.
 For example, to delete the hosts database, the hosts.time entry should be removed.
 3. Remove the time rule.
 For example, to delete the hosts database, the hosts: hosts.time entry should be removed.
 4. Remove the map from the master and slave servers.

.... and what to look for
Notice the difference in how flat these primers are.
Examining the flatness of your fired primers is the best way to read
chamber pressure. It's important to keep an eye on this when you're reloading. These 4 fired cases clearly show the different degrees
of chamber pressure, and this is an accurate representation when reloading any caliber. If you pay close attention to your fired cases, and
you slowly work your way to hotter loads, you'll avoid seeing any of the "serious" pressure signs.
Some brands of primers have a noticeably harder cup than others. This difference in hardness can cause a slight
variation in your pressure readings. Seating bullets too short or too long will affect chamber pressure considerably, and some types of powder
will increase pressure as the outside temperature increases. When you develop maximum loads in the winter, beware of the pressure increase
when using those handloads in the heat of summer.
- Very mild load (this is too mild).
- Mild load.
- This is an ideal load (could go just a bit hotter).
- Absolute Maximum load (approach this pressure very carefully).

Mathematical model 'describes' how online conflicts are resolved
20 Feb 13
Researchers have produced a mathematical model to describe how conflicting opinions are resolved over articles that appear on Wikipedia, the collaboratively-edited encyclopaedia.
The study maps the evolution of opinion over time, showing that even widely diverging opinions eventually converge. The researchers say this pattern in collective human behaviour is reminiscent of the interaction of particles in physics, such as when wind-blown grains of sand eventually create sand dunes. The study also notes that the collaborative nature of a medium like Wikipedia tempers extremes of opinion.
The model, which appears in the journal Physical Review Letters, was constructed by a research team, including Dr Taha Yasseri from the Oxford Internet Institute at the University of Oxford, as well as researchers from Hungary, Finland and Spain.
Dr Yasseri says: 'We believe this model exhibits some interesting behaviour that for the first time can qualitatively capture key characteristics of off-line conflicts.
'The competition and co-existence of local and global interactions play an important role in physics. For example, we have already observed this in the creation of sand dunes, which are not solely formed by the local interaction of sand grains with neighbouring grains but also the wind, which brings into play global and long-range effects. To understand the emergence of editors' opinions, again we see both the direct interactions of editors with each other and the global interactions of editors altering a shared medium.'
In the presence of an article a collective behaviour appears, conflict followed by consensus, not unlike in chemical synchronisation and sand ripples.
At the outset, the researchers mapped widely differing opinions amongst the 'editors' of three articles that appeared on Wikipedia about the Dresden bombing, Japan and anarchism. Editors were seen to influence each other either through direct communication or indirectly by modifying the online Wikipedia article.
The researchers found that when a fixed number of individuals form one'mainstream' and two opposing 'extremist' groups, consensus in the medium's content is achieved, but only after a long time and this may not correspond to the initial mainstream view. In the case of a dynamic environment where new editors replace existing ones, they found periods of conflict and consensus can alternate indefinitely, depending on the rate of newcomers and the degree of controversy in the article's topic.
The group's model describes the spontaneous dynamics of the clashes of opinions in Wikipedia in three types of scenarios: First, it shows how increasing the number of new editors to an article gives rise to controversy. The model also accounts for different levels of tolerance in editors' sensitivity towards certain topics. Moreover, it captures states of uninterrupted controversy where sensitive contributors cannot stand even small deviations from their opinions. However, it shows that eventually even strongly opposing views converge over time, even without direct interaction between dissenting contributors. The researchers conclude that the shared medium takes care of this.
'The presence of the Wikipedia article itself brings the opinions of individuals together and helps the convergence process. Without an article on which to work collectively, groups with different opinions could stay separate and ignore each other,' explains Gerardo Iñiguez, doctoral student in the group and in Aalto University Department of Biomedical Engineering and Computational Science.
'Usually sand grains only collide with neighbouring grains, but wind can project them into the air and make them hit faraway grains. This long-range global interaction creates a ripple pattern that does not appear in the absence of wind,' adds Iñiguez.
Dr Yasseri concludes: 'In Wikipedia local interactions occur between editors modifying their opinions, while global interactions are those of the editors with an article. In the presence of an article a collective behaviour appears, conflict followed by consensus, not unlike in chemical synchronisation and sand ripples.'
János Kertész from the Center for Network Science, Central European University, Hungary explains: 'New media produce an efficient collaborative environment but with collaboration comes conflict. Wikipedia is an important example because every single change is documented and publicly available. It's a goldmine for research.
'Our model is a tolerance model: If the article is very different from an editor's opinion, they are more likely to change the article. If it's close to their opinion, the editor is less likely to change it. Is usually a few people who are rigid and keep the edit war going.'

Worms Detect Cancer by Scent
By Iva Fedorka
You may have read stories about cats and dogs that seem to sense when someone is sick. Now, scientists are studying whether small worms can use chemosensation to detect early disease processes.
If small worms could "smell" lung cancer cells, perhaps a device incorporating them could help provide an easy and painless way to screen for disease. A team from Seoul, Korea, introduced its "worm-on-a-chip" in March 2022 at a meeting of the American Chemical Society held in San Diego, California.
Choosing an Animal Model
The most likely candidate for this model is the common roundworm, Caenorhabditis elegans. Because they're about a millimeter in length, multiple worms could easily fit in a small space.
Although C. elegans cannot see or hear, their sense of smell is good. In fact, the worms have roughly the same number of genes for chemical sensing as dogs, mice, and other mammals known for their sense of smell.
Shin Sik Choi, a biotechnologist who helped develop the system at Myongji University in Seoul, South Korea, thinks scent is the likely source of the worms' attraction to cancer cells. This is because the diseased cells release odor molecules. "In nature," he explained to Science News for Students, "a rotten apple on the ground is the best place where we are able to find the worms."
The Sense of Smell
Which scents stimulate C. elegans nerve cells? Choi and his team tested some volatile organic compounds or VOCs produced by cancer cells and identified floral-scented 2-ethyl-1-hexanol as a prime candidate.
The human brain has about 86 billion nerve cells or neurons, but C. elegans has only 302 nerve cells in total. Since the worm bodies are transparent, scientists can actually determine the specific nerve cell that reacts to cancer cell aromas by having it fluoresce when stimulated.
To test their hypothesis, the team used a special strain of genetically modified C. elegans with no 2-ethyl-1-hexanol receptors. While the unmodified worms preferred cancer cells over healthy ones, the modified worms did not, which may mean that 2-ethyl-1-hexanol has a role in attracting the worms to diseased cells.
Making the Screening Device
The researchers created a microscope slide-like construct with three large indentations or wells. Healthy human cells were placed in a well at one end and lung cancer cells added to a well at the other. Approximately 50 worms were put in the middle well where they could smell the cells at either end.
"About 70 percent of the worms move toward the cancer," says Choi. He also believes that percentage could be increased with training.
Choi also wants to test whether the worms can still detect cancer without being directly exposed to diseased cells. A recent study by another researcher (Scientific Reports, August 24, 2021) showed that C. elegans preferred the urine of patients with breast cancer over samples from healthy subjects.
Noninvasive screening tests that use a patient's blood, urine, or saliva may one day help detect cancer in its early stages, which would help speed diagnosis and treatment.

Power of Microsoft Lync
Microsoft Lync Server is unified communications (UC) platform which provides an infrastructure to integrate communication modalities like instant messaging (IM), Presence, VoIP (voice over IP), file transfer, Web conferencing, voice mail and email etc. Microsoft Lync enables seamless communication within a single organization, between multiple organizations, and with external individuals.
Why Information Barrier?
While seamless communication helps companies to increase their ability to reach internal/external workforces brilliantly, it throws compliance challenges to some of the industries. With so much information created, saved and accessible via collaboration tools, it becomes equally important to ensure internal and government compliance are met during this seamless form of communication between the agents.
For example, there could be an investment banking firm with requirement to isolate persons who make investment decisions from persons who are privy to undisclosed material information which may influence those decisions. These firms are generally required by law to safeguard insider information and to ensure that no improper trading occurs.
Journalism industry also needs ethical wall to meet internal compliance/regulatory. Ethical wall is used in journalism to create separation between the editorial and advertising arms of a media firm.
Similarly there are various industries like pharma, law etc. where ethical wall is required to create information barrier between two set of workforce.
Solution for Microsoft Lync
Recognizing the importance of compliance & regulatory laws, DevCentrics has released a product DC Stockade for Lync customers. DC Stockade is an information barrier or ethical wall or Chinese wall, which takes strong measures to protect information flow using Lync modality between two set of users or networks.
Noticeable Features of DC Stockade
- Information barrier: Lync customers can chose to control access per modality (IM, presence, voice, video, etc).
- Target Definition: You can implement china wall based on users group or VLAN.
- Federated Domain: You can either block or allow communication with federated partners.
- Content Filter: It enables content filter in the Lync environment. You can create different levels of profanity words to apply policies and alerts accordingly. DC Stockade allows you to configure alerts based on violations.
- IM Bot: To pop the regulatory statement to users when violation occurs.
- Archival of violations: DC Stockade records the archival of violations for future references.
- Hardware requirement: No additional hardware requirement as it runs on the front end server.
- Environment support: DC Stockade supports multiple active directory domain and Lync pools. It supports standard and enterprise edition both type of deployments.
- Advanced reporting: DC Stockade has rich reporting options on violations.
- RBAC: Access of UI based on Role Based Access Control (RBAC).
Adoption of Lync
Adherence of compliance and regulatory takes precedence over implementation & adoption of seamless communication for most of the organizations. Hence, many organizations end up not enabling Microsoft Lync for various users to maintain information barrier compliance requirement. This practice leads to less adoption of Microsoft Lync, which in turn decreases ROI. DC Stockade helps such organizations to implement Microsoft Lync for all, yet follow the compliance and regulatory requirements. This helps those organizations immensely in order to increase adoption of MS Lync and increased ROI.
You can contact Devcentrics (_EMAIL_) to know more benefits and how it could help your organization.

Let $A$ be a $2\times2$ matrix with real entries such that $A^2=0$.Find the determinant of $I+A$ where $I$ denotes the identity matrix. I proceed in this way :Note that $(I+A)A=A+A^2 \Longrightarrow (I+A)A=A$ (Since $A^2=0$).
Now taking determinant both side we get $|(I+A)A| = |A| \Longrightarrow |(I+A)|\cdot|A|=|A|\Longrightarrow |I+A|=1$.
Am I proceed in correct way? In the last line am I need to consider $|A|=0$?
share|improve this question
Since $A^2=0$ $A$ is not invertible, therefore $|A|=0$, so your proof is not correct. – sebigu Aug 2 '12 at 13:25
Better consider the characteristic polynomial of $A$. You can compute the one from $A+I$ from it and read out the determinant. – sebigu Aug 2 '12 at 13:27
As an alternative to _USER_'s hint: you can show that a nilpotent matrix is similar to a strictly triangular matrix. Now, what is the determinant of the sum of the identity and a strictly triangular matrix? – Guess who it is. Aug 2 '12 at 13:33

The matrix $A$ is nilpotent with characteristic polynomial $x^2.$ But by definition $x^2 = \det(A - xI).$ If we let $x = -1,$ then we have $\det(A + I) = 1.$
share|improve this answer
This is the simplest way. Than you for help – Argha Aug 2 '12 at 14:16
$A$ is similar to (and hence has the same determinant as) a matrix of the form $\begin{pmatrix} 0 & * \\ 0 & 0 \end{pmatrix}$. That is, there is an invertible matrix $P$ such that
$$A':=P^{-1}AP = \begin{pmatrix} 0 & * \\ 0 & 0 \end{pmatrix}$$
and $\det A = \det A'$. But $I':=P^{-1}IP=I$, and so $P^{-1}(I+A)P=I+A'$, and so $\det (I+A) = \det (I+A')$.
So what is $\det (I+A)$?
share|improve this answer
Let $x = \det (I+A)$
Hence $\det(I+nA)=x^n$
But $\det(I+nA)=P(n)$ with P a polynomial (of maximum degree the size of matrix A).
So the only solutions are $x=1$ or $x=0$. But If $x=0$, there is a $v\neq 0$ such that $v+Av=0$, hence, $Av=-v$, and $A^2v=v$, that is not possible.
So $\det(I+A)=1$
Note that this proof is true for any size of matrix.

Very nice answer, +1 – Clive Newstead Aug 2 '12 at 14:01
I like this one:
The characteristic polynomial of $A$ is $x^2$. By substitution we get $$(x-1)^2=x^2-2x+1$$ as characteristic polynomial of $A+I$. Now we see trace and determinant.
share|improve this answer
The trace of $A$ is $0$, using $$A^2-\operatorname{tr}(A)\cdot A+(\det A)\cdot I=0$$ and the fact that the determinant of $A$ is $0$. Applying this to $A+I$, we get $$\tag{1} A+2I-\operatorname{tr}(A+I)\cdot(A+I)+\det(A+I)\cdot I=0,$$ hence $$2A+I-2(A+I)+\det(A+I)\cdot I=0,$$ and $$\det(A+I)\cdot I=I,$$ hence $\det (A+I)$.
The formula $(1)$ can we deduce either by Cayley Hamilton theorem (sledgehammer), or by hand.

- Homestead withdrawal mechanism refers to a whole set of mechanisms with homestead withdrawal behavior as the core, including both homestead-centered withdrawal mechanism and compensation and guarantee mechanism to ensure the smooth realization of homestead withdrawal behavior. Its main function is to promote the smooth realization of homestead withdrawal behavior, improve land use efficiency, and promote the development of urban-rural integration. However, our country's homestead withdrawal mechanism is not perfect, and there are a series of problems, mainly including vague property rights of homestead, incomplete real rights and powers of the right to use homestead, lack of fixed-term paid use system of homestead, and defects in the conditions for the withdrawal of homestead. Through the analysis of the current pilot areas for withdrawal of residential land represented by concentrated residence, drawing on the successful experience, the existing problems are found out, and the withdrawal mechanism of rural residential land based on the coordinated development of urban and rural areas is analyzed.

How to Create a Custom LinkedIn Profile URL
Close up of a laptop with the Linkedin homepage open.
Justin Sullivan / Getty Images
 For home business owners and freelancers, LinkedIn offers a tremendous opportunity to promote your business, network with influencers, and build your professional online presence. However, when you initially join LinkedIn, you're given a long, difficult to remember profile URL. This can be a problem when trying to share it with others you want to network with. The solution is to create a custom URL for your LinkedIn Profile that can make it more recognizable and easier to use.
By customizing your URL, you'd change:
(The caps are to show you what you can change. Your Linkedin Profile URL doesn't require caps.)
Why You Might Want a Custom LinkedIn URL
There are several reasons to create a custom URL on LinkedIn. One is for search engine optimization (SEO). Search engines, including Google, use keywords within a URL to help it decide what web pages to deliver in search results. A URL of would have a better chance of ranking well in Google for a search using the keywords "freelance writer Ohio" than would the first URL of
Another reason to create a custom Linkedin URL is ease of use and recognition. Having a line of numbers at the end of a URL looks messy and difficult, and it's more likely to be ignored. Whereas, a URL with your or your business' name at the end will be clear what it's linking to. While LinkedIn URLs aren't as straightforward as they could be, the custom URL is still easier to remember than the default one.
Choosing Your Custom URL Profile Name
You have a few options in creating your custom URL. One is to use your given name, such as Joe Smith. The other option is to use your business name. Finally, you can use a combination of the two, such as Joe Smith Freelance Writer. Some things to consider when deciding what to use include:
 - What are you branding? Do you want you or your business name to be the focus of your endeavor? How do you want to be known in the professional world?
 - How easy is it to use? While combining your name and business allows you to use both, it also creates a long URL that can be difficult to use if people have to type it in (i.e. off of a business card).
 - Will your name change? Traditionally, this is more of a problem for single women who get married and decide to take their husband's name. However, I've seen many couples hyphenate both their names, in which case, it impacts men, as well. In this case, using your business name might be better.
You are allowed to change your LinkedIn customer URL up to five times in a 180-day period; however, this is not advised. First, changing your URL means you have to update it everywhere you used the old URL. Further, people with the old URL will have difficulty finding you. Finally, after 180 days, someone else can use your old URL, which could potentially lead your clients and customers to the other person instead of you. For this reason, pick a name you know you can live with for a long time.
How to Create a Custom URL for a LinkedIn Profile
The instructions below work on your public profile.
 1. Log into LinkedIn.
 2. On the main menu bar at the top of the page, hover over Profile with your mouse and select Edit Profile.
 3. Hover your cursor over the current profile URL under your profile picture. The settings icon will appear next to the URL. Click it.
 4. On the right-hand side of the page, you'll see a section that says, Your Public Profile URL. Click on the edit icon next to it.
 5. In the edit box, type the custom name you'd like in your URL. You can have five to 30 letters or numbers, but no symbols or special characters (i.e. you can't use "*" or "!"). Your custom name is NOT case sensitive, so JoeSmith and joesmith will both work in the URL. When you're done, click Save.
 6. If your custom URL isn't already in use, you're all set. If it is in use, you'll need to submit a new custom URL. You can add your middle initial or your business name or type to create a unique URL. For example, if JoeSmith is taken, you can use, "JoeQSmith," "JoeSmithSellingWords," or "JoeSmithCopywriter."
Be sure to update your new LinkedIn URL on your website, blog, and other marketing materials.

]]>
Alzheimer's disease is a devastating condition that affects millions of people worldwide. As the search for a cure continues, many individuals are turning to Alzheimer's supplements to support their brain health and potentially unlock the potential of their minds. With a wide range of options available on the market, it can be overwhelming to navigate through the various products and determine which ones are truly beneficial.
Are Alzheimer's supplements the key to improving brain health? While there is no magic pill to cure or prevent Alzheimer's disease, certain supplements have shown promise in supporting brain function and potentially slowing down cognitive decline. It's important to understand the potential benefits and limitations of these Alzheimer's supplements, as well as consult with a healthcare professional before incorporating them into your routine. By exploring the science behind these supplements, we can gain a better understanding of their potential role in brain health.
The Role of Alzheimer's Supplements: Can They Improve Brain Function?
When it comes to maintaining a healthy brain, many of us are looking for ways to unlock its full potential. One avenue that has gained attention in recent years is the use of supplements. These dietary additions are thought to have the potential to improve brain function and address cognitive decline associated with Alzheimer's disease. While more research is needed to fully understand their effects, initial studies have shown promising results.
Exploring the Potential Benefits of Alzheimer's Supplements
Alzheimer's Supplements are not a magic cure for Alzheimer's or other cognitive disorders, but they may play a role in supporting brain health. Some Alzheimer's supplements contain antioxidants, which can help protect brain cells from damage caused by free radicals. Others may contain ingredients that support neurotransmitters, the chemical messengers that facilitate communication between brain cells.
It's important to note that Alzheimer's supplements should never replace evidence-based treatments or medications prescribed by healthcare professionals. However, they may be used in conjunction with other strategies, such as a healthy diet and regular exercise, to optimize brain health.
Omega-3 Fatty Acids: Boosting Cognitive Abilities
One supplement that has garnered significant attention is omega-3 fatty acids. Found in fatty fish, walnuts, and flaxseeds, these essential fatty acids are crucial for brain health. Not only do they play a role in maintaining the integrity of brain cell membranes, but they also support the production and function of neurotransmitters.
Examining the Role of Omega-3 Fatty Acids
Research suggests that omega-3 fatty acids may have a protective effect against cognitive decline and reduce the risk of Alzheimer's disease. A study published in the Journal of Alzheimer's Disease found that individuals with higher levels of omega-3 fatty acids in their blood had a lower risk of developing Alzheimer's compared to those with lower levels.
Additionally, omega-3 fatty acids have been shown to improve cognitive abilities in individuals without Alzheimer's disease. A meta-analysis of several studies, published in the journal PLoS One, concluded that omega-3 supplementation may improve episodic memory, which is essential for remembering personal experiences and events.
Vitamin E: Protecting Against Oxidative Stress
Oxidative stress is a natural process that occurs in our bodies. It happens when there is an imbalance between the production of free radicals and the body's ability to neutralize them. Free radicals are highly reactive molecules that can cause damage to cells, including brain cells. This damage has been linked to the development of neurodegenerative diseases like Alzheimer's.

Background: There is a recognized need to deliver oral health information to people during clinical encounters to enable them to develop personal skills in managing their own oral health. Traditional approaches to individual oral health education have been shown to be largely ineffective and new approaches are required to address personal motivations for preventive behaviour. This systematic review aims to identify and assess the effectiveness of behaviour models as a basis for individual oral health promotion.
Methods: Electronic databases were searched for articles evaluating the effectiveness of health behaviour models in oral and general health between 2000 and 2007. Eighty-nine studies were retrieved and data were extracted from the 32 studies that met the inclusion criteria.
Results: Thirty-two studies were identified in the fields of clinical prevention and health education, motivational interviewing (MI), counselling, and models based interventions. MI interventions were found to be the most effective method for altering health behaviours in a clinical setting.
Conclusions: There is a need to develop an effective model for chairside oral health promotion that incorporates this evidence and allows oral health professionals to focus more on the underlying social determinants of oral disease during the clinical encounter. There is potential to further develop the MI approach within the oral health field.


Let's Talk about Regulation and IMO 2020
IMO 2020 low sulfur regulations will a significant impact on the petroleum industry.
October 2017 - Regulation in the petroleum industry is a frequently discussed topic. In the Canadian landscape, the mere mention of the word'regulation' evokes highly polarized feelings.
Many of those in the Canadian extractive energy sector feel that regulation unnecessarily adds to the cost of production, thereby serving as a disincentive for businesses. In contrast, regulatory proponents argue that responsible resource development and environmental stewardship are paramount for the long term sustainability of modern society.
Regulatory Impacts in Canada
While Canadian federal government has detailed a plan to put a price on carbon starting in 2018, some provincial governments, such as Alberta's and British Columbia's, have already rolled out their own carbon pricing programs. Companies operating in these jurisdictions must now budget and adjust their investment strategies by accounting for the added costs. Conversely, Saskatchewan's premier has marketed his province as a carbon tax safe haven and has gone so far as to announce his preparedness to take the federal government to court over the issue.
Regulation has also impacted pipeline approvals in Canada. In late 2016, the federal government approved the Kinder Morgan Trans Mountain and Enbridge Line 3 pipelines, while simultaneously rejecting Enbridge's Northern Gateway project. More recently, TransCanada announced the withdrawal of its Energy East pipeline proposal, citing uncertainty in the cost and timing of the regulatory process.
Whether you are a Canadian stakeholder or an outside spectator, there is something important to be learned from the Canadian story: regulation cannot be ignored and it will have a tangible impact on business in the oil patch.
While Canadians are still busy debating the merits of a carbon tax and extensive pipeline approval processes, another regulatory specter looms on the horizon. Unlike the local carbon tax and pipeline debates, this regulation will have a more widespread impact because it reaches far beyond the Canadian jurisdiction. So what is this regulation? IMO 2020.
The International Maritime Organization and IMO 2020
The International Maritime Organization ("IMO") is a specialized agency of the United Nations. Established in Geneva in 1948 and currently headquartered in London, the IMO seeks to create "a regulatory framework for the shipping industry that is fair and effective, universally adopted and universally implemented". Currently, the IMO has 172 Member States and 3 Associate Members.
The IMO has played a pivotal role in developing regulations surrounding maritime safety, security, and environmental protection. Regulations for the Prevention of Air Pollution from Ships are covered in Annex VI. Those regulations specifically address sulfur oxide (SOx) and nitrous oxide (NOx) emissions.
Since 2012, the sulfur content in marine fuel oil has been capped at 3.5% m/m (mass by mass). In 2016, the IMO announced a 2020 effective date for globally reducing sulfur content in marine fuel oil to 0.5% m/m. This initiative has been dubbed 'IMO 2020'.
Why You Should be Concerned
We now live in a global economy. Due to the supply chain also being globalized, interests both upstream and downstream from affected shippers will also be impacted due to a ripple effect from the imposed global regulation.
In this case, should the IMO 2020 regulation add incremental costs to shippers? Some of those costs will likely get passed onto the consumer downstream. Likewise, since IMO 2020 places a more stringent restriction on fuel oil sulfur content, shippers are now incentivized to seek out alternative fuel sources in order to maintain compliance, which affects suppliers upstream.
To date, global refiners have led the discussion on how best to tackle IMO 2020. At the core of these discussions lies the question: what makes the most economic sense? While some refiners have signaled that they are looking into revamping their operations to produce a lower sulfur product from existing feedstock, other refiners are tendering the idea of simply changing to lower sulfur-containing feedstock altogether.
From Canada's perspective, this shift could be devastating as the majority of exported raw bitumen contains 2.0-5.0% sulfur content. By sitting back and allowing the status quo to run its course, the Canadian petroleum industry could very quickly find itself in a weakened bargaining position.
According to Houston-based Edwards Energy Consultants, the effect of new sulfur limits will lower heavy oil prices, increase competition between heavy oil-producing jurisdictions, and ultimately force Canada to shut-in some of its production due to economics if precautionary steps are not taken. They have called on local governments and the petroleum industry to seriously consider low-cost technologies that could selectively remove sulfur-containing compounds from Canadian heavy oil.
Globally, we have also seen indicators that other players in the primary petroleum extractive business are already preparing for IMO 2020. It is widely known that Saudi Arabia has been trimming its production due to OPEC cut agreements. However, a closer look has shown that most of the production being taken offline is Arabian Heavy, which contains 3.0% sulfur content. While it may be debatable whether IMO 2020 is a primary influencer behind the Saudi strategy, it would certainly be a consideration at the least.
Proposed Solutions
In its 2016 announcement, the IMO pointed to an increasing number of ships using LNG as a negligible sulfur oxide-emitting fuel alternative. Industry discussions have noted the lack of LNG infrastructure, the need for additional on-board LNG storage space, and the cost of LNG itself would be limiting factors to making a full transition. The IMO also pointed to methanol as a potential alternative low sulfur fuel, but cost once again becomes an issue.
The IMO suggested that sulfur oxide emission requirements could be met through "equivalent methods" such as the installation of exhaust gas cleaning systems, or scrubbers. However, this option does not provide for a widespread solution, as scrubbers would need to be retroactively installed on thousands of ships, and can cost millions of dollars per ship. This option may only be a solution on a case by case basis.
Some have asked whether non-compliance is a viable option. Currently, there is uncertainty surrounding enforcement actions and the magnitude of non-compliance penalties. Moreover, noting the importance that today's society places on environmental sustainability, non-compliance should not be contemplated.
Others have proposed blending as another solution. This option entails blending high sulfur-containing fuel oil with more expensive low sulfur-containing fuels in order to meet specifications. Given that there is a limited market for marine fuel oil, this option would conceivably lead to an oversupply situation, which would lead to an array of other problems for the market.
A Call for Innovation
The petroleum industry appears optimistic for innovation as a long-term, sustainable answer to IMO 2020. There are varying opinions on what this innovation looks like. One commentator may suggest that innovation entails developing technologies that turn high sulfur-containing feedstock into other products, bypassing fuel oil production altogether. Another commentator may advocate that innovation entails the development of more efficient and cost-effective sulfur removal processes.
Whatever that innovation looks like, we need to ensure that we build a culture of support around innovators that are looking to solve tomorrow's problems. At the same time, we, as stakeholders need to acknowledge and understand the policy in order to prepare ourselves for when the regulation comes into effect.

Iceberg Lake Typical Of All
( Originally Published Early 1900's )
In some respects Iceberg Lake is Glacier's supreme spectacle. There are few spots so wild. There may be no easily accessible spot in the world half so wild. Imagine a horseshoe of perpendicular rock wall, twenty-seven hundred to thirty-five hundred feet high, a glacier in its inmost curve, a lake of icebergs in its centre.
The back of the tower-peak of Mount Wilbur is the southern end of this horseshoe. This enclosure was not built up from below, as it looks, but bitten down within and without; it was left. On the edge of the lake in early July the sun sets at four o'clock.
Stupendous as Iceberg Lake is as a spectacle, its highest purpose is illustrative. It explains Glacier. Here by this lakeside, fronting the glacier's floating edge and staring up at the jagged top in front and on either side, one comprehends at last. The appalling story of the past seems real.


Is the football coach a teacher or not
Is football coach in particular, and sport in general, considered to be a teacher? Or are they merely a collaborator with an athlete?
If judging by the standards of professional football in particular and top sport in general, it is clear that the coach is not the right teacher. It is a pure working relationship, based on commitments that both are bound to a common organization.
Những huấn luyện viên cá tính nhất của làng bóng đá thế giới | Bóng Đá
In binding the commitment that leads to their relationship in the other job, the coach is like a "boss" and a player as a special employee. Together they conquer goals that one is a "thinker" and one is a "doer".
But also in that relationship, there are many pairs of football coaches – players who are close to the level of a junior associate. Many players consider the coach to be like his father, a position quite similar to that of his mentor.
For example, Mourinho's relationship with Materazzi at Inter Milan, for example. Moreover, there are coaches who train their players and when they teach behaviors. surely they must have a teacher – student relationship.
Typically the story of Pochettino coach of Tottenham when he was a player. At the time, Pochettino was in his early 20s, playing center-back at Newell's Old Boys club and Mercelo Bielsa was the head coach.
Nét bốc lửa của huấn luyện viên đòi cứu vớt gấu Nga | Bóng Đá
That is what an assistant coach must do, not a player's task. But Bielsa sees the quality of coaching in the person of Pochettino. And he taught Pochettino more of a coach than a player. Now, as a famous coach, Pochettino still remembers those lessons and always calls Bielsa the teacher.
The aforementioned stories clearly show that not in the West, all relationships are so separate that the coach is a coach, not a teacher. And this relationship, in the Asian cultural environment, is increasingly tightened. With the majority of players, Asian athletes, coaches are always considered teachers. Or at least, in their lifetime, there will be some coaches they are exalted as teachers.

We tested the hypothesis that the lipid composition of infant formula is consistent between manufacturers, countries and target demographic. We developed techniques to profile the lipid and glyceride fraction of milk and formula in a high throughput fashion. Formula from principal brands in the UK (2017–2019; bovine-, caprine-, soya-based), the Netherlands (2018; bovine-based) and South Africa (2018; bovine-based) were profiled along with fresh British animal and soya milk and skimmed milk powder. We found that the lipid and glyceride composition of infant formula differed by region, manufacturer and date of manufacture. The formulations within some brands, aimed at different target age ranges, differed considerably where others were similar across the range. Soya lecithin and milk lipids had characteristic phospholipid profiles. Particular sources of fat, such as coconut oil, were also easy to distinguish. Docosahexaenoic acid is typically found in triglycerides rather than phospholipids in formula. The variety by region, manufacturer, date of manufacture and sub-type for target demographics lead to an array of lipid profiles in formula. This makes it impossible to predict its molecular profile. Without detailed profile of the formula fed to infants, it is difficult to characterise the relationship between infant nutrition and their growth and development.

text: Kyaukpahto gold mine located in the Kawlin Township, Sagaing Region of Myanmar is the first open pit and the largest gold mine of Myanmar. As the gold is exploited by open-pit mining, a large amount of waste rocks are disposed at waste dumps near the mine site. The metal sulfides such as pyrite, arsenopyrite, and chalcopyrite in the waste rocks are exposed to the surface, favoring the oxidation of these metal sulfides and generating acidic water. There is a possibility of AMD generation in the open pit and at the low grade ore dump. This work focuses on assessment of the potential acid-forming waste rocks and characterization of these waste rocks in Kyaukpahto gold mine. Waste rocks and water samples were taken from the open pit, low grade ore dump, and waste dumps and subjected to various tests and analyses such as NAG test, Paste pH test, Paste EC test, ANC test, XRF, XRD, and ICP-MS analyses. Based on the results of the chemical tests and analyses, waste rock samples collected from open pit and low grade ore dump are identified as PAF rocks which particularly concerned with the potential generation of acidic mine water. Two-step batch leaching test indicated that low pH value (pH 4) and elution of metal ions such as As, Al, Fe, Cu, Zn, and SO42-were observed with the high concentration from the samples. Elution of As is higher than other metal ions and this elution process will take place over a longer period than other metal ions. Thus, it is very critical to take appropriate measures against generation of AMD, such as controls on sulfides oxidation, and reduction of metals elution.


LinkIt ONE Pager

Who uses a pager anymore? Well actually, lots of people. Pagers are still pretty popular among people who need to know things in a hurry because having internet all the time (even with 4G) still isn't as reliable as a good old pager.
In this tutorial, we'll use the LinkIT ONE to create our very own pager. Due to the LinkIT ONE's powerful capabilities, such as a built in battery pack and GSM slot, we can easily manipulate certain components that would take much more hardware and skill on a regular old Arduino.
Step 1: Supplies
If you got the Arduino Grove Starter Kit, you should be in business fairly quickly. Otherwise, you'll need to obtain some of these things on your own:
 - LinkIt ONE
 - Pre-paid SIM Card
 - Grove Arduino Base Shield
 - Grove - LCD RGB Backlight
Step 2: Configure Your LinkIT ONE Board
We'll need to modify some of the switches on the LinkIt One board in order to make it work. Along with the image attached, make sure that you have done the following
1. Set the MS -- UART switch to UART
2. Set the USB -- BAT switch to USB
3. Set the SPI -- SD switch to SPI
Connect the GSM Antenna in order to receive Text Messages and phone calls!
Step 3: Insert Your Sim Card
I know that most people probably don't have a pre-paid SIM card laying around. If you are just prototyping and want to see a proof of concept, feel free to remove it from your current cell phone (or one of your friends) just to try it out. If you get serious and want to make this a full-time gig, you will have to pony up for a pre-paid SIM.
Inserting the SIM card is a fairly straight forward process. Flip over your LinkIt One and look at the smaller big metal piece. You can see in the figure where I inserted my SIM card if you are confused.
After you have inserted the SIM card, be sure to attach your GSM antenna that came with your LinkIt One kit. This will allow you to get a cell signal.
Step 4: Attach Grove Board and LCD
The LinkIT ONE has the same pin layout as the arduino, thus an arduino grove board extension fits on top of it in a very similar fashion. Simply line up all the pins and plug it in.
Then, you're going to want to attach the Grove RGB LCD into an I2C slot. This will allow us to interact with it.
Step 5: CODE I - Interacting With the LCD
First, let's go over some basic LCD code. You'll need to install this library in order to interact with the LCD on your LinkIT ONE Board. This is a special library that allows us to easily send commands to the Grove LCD. We will use this board in the later code file to print out the number that texted us and the message.
Use this example file to quickly understand the Grove LCD.
Step 6: CODE II - Receiving a Text Message
Next, let's go over how exactly we will receive a text message. We'll make extensive use of the LGSM library, so it might help to read up on that a bit. There are some great online resources if you wish to do that.
First, we want to catch a text message. Following the logic within the loop() function...
if(LSMS.available()) // Check if there is new SMS {
This giant if block checks to see if a new text message is available. If it is, let's continue and go and parse it.
LSMS.remoteNumber(p_num, 20); // display Number part
Serial.println("There is new message."); Serial.print("Number:"); Serial.println(p_num); Serial.print("Content:"); // display Content part
Next, we print some basic debugging info. When this thing is deployed, we probably don't care much about the serial output, but it is always good practice to print this out just in case we want to go back and take a look.
while(true)
{ int v = LSMS.read(); if(v < 0) break;
 dtaget[len++] = (char)v;
 Serial.print((char)v);
 }
Next we're going to read the text message. It's a little difficult because with this embedded technology, it's not so simple as 'String = textMessage.read();'. Instead, we have to read the bytes from the text message character by character, forming an array of characters that is our eventual message. This is done in the above while loop.
LSMS.flush(); // delete message
Now, to save space on the device, we'll 'flush' or delete the message.
And that's more or less it! Now let's combine the two to create our pager...
Step 7: Code III: Putting It All Together
Now, we'll combine both the LCd and Text messaging library to receive a text, and show it on our LCD. I've put in a bit of extra code to help polish it up a bit. Hopefully the comments can help you follow along.
Copy this code over to your arduino IDE and deploy!
Step 8: Conclusion
Clearly the LinkIT ONE is a very powerful prototyping device. Hopefully this tutorial has taught you a thing or two about it and how we can create some really cool projects with it.

U.S. Department of Justice: Supporting Male Survivors of ViolenceDeadline: June 17, 2015
The Office for Victims of Crime (OVC) seeks innovative proposals that will create equal access to both system and community-based service providers for male survivors of violence, particularly boys and young men of color, to catalyze a national commitment to better serve these individuals. OVC is particularly interested in proposals that seek to strengthen victim service providers' knowledge and skills, resulting in innovative programs and practices that foster a better understanding among criminal and juvenile justice systems and guide service providers around the needs and rights of these boys and young men. OVC seeks applications that address one of the two purpose areas identified below:
- Purpose Area 1, Demonstration Projects: This solicitation will fund demonstration sites that put in place evidence-based models and practices to provide trauma-informed, comprehensive services for male survivors of violence, particularly boys and young men of color, and their families and supporting policies.
- Purpose Area 2, Technical Assistance Providers: This solicitation will be used to select up to two distinct technical assistance (TA) providers to support the demonstration sites in the following categories: (A) Comprehensive TA: To deliver comprehensive information, training, and technical assistance to support the demonstrations sites, including subject matter expertise, training on identified topics, and peer-to-peer learning exchanges; and (B) Communications TA: To assist the demonstration sites with outreach efforts aimed at educating stakeholders and the broader community on the adverse effects of trauma and violence as well as the importance for community and system-based services to communicate and develop consistent policies, procedures and messaging to enhance efforts to reach and identify victims and survivors.
Eligibility: Varies by purpose area:
- Purpose Area 1: Eligible applicants for the demonstration project are limited to: state and local
agencies; federally recognized tribal governments (as determined by the Secretary of the Interior; private nonprofit organizations (including tribal nonprofit organizations); faith-based and community-based organizations; and colleges or universities (including tribal institutions of higher education) that demonstrate an understanding of the area of victimization and support services described in the solicitation.
- Purpose Area 2: Eligible applicants for funding to provide technical assistance to the demonstration projects are private nonprofit organizations, colleges and universities or public agencies (including tribal nonprofit organizations and tribal institutions of higher learning).
Amount: Varies by purpose area:
- Purpose Area 1: 8-12 awards of up to $1,000,000 each for a 36 month project period.
- Purpose Area 2: Up to 2 awards of up to $1,000,000 each for a 36 month project period.

Dubbed the Kyoto Process, the work could yield car parts five times stronger than steel but a fifth of the weight, according to The Drive.
Cellulose nanofibers are already used in a number of commercial products, but the new process kneads chemically treated wood fibers into plastics to create a material strong enough to be used in auto parts.
While the Kyoto nanofibers are cheaper than carbon fiber—another material being eyed for renewable auto parts—they are still too expensive to be commercially viable. Tensile steel and aluminum alloys cost $2/kg, while Kyoto's materials cost about $9/kg.
Kyoto University professor Hirokai Yano tells The Drive he expects the cost of the Kyoto Process to be halved by 2030, at which point it will start being economically viable for mass production. A prototype car made out of cellulose nanofibers is nonetheless planned for 2020.

Inlet Manifold Gasket Replacement
The Inlet Manifold Gasket is between the engine and the air intake manifold and it seals both parts together. It allows the air/fuel mixture to go through the air inlets into the engine, ready for combustion inside the engines cylinder. The Inlet Manifold gasket also is used to cool the engine coolant that can flow through it.
How to tell when its worn
- A key indicator could be if your 'Check Engine' light is on.
- If your engine is over heating, or running at a higher temperature than usual.
- If there is fluid underneath your vehicle, this could indicate a work inlet manifold gasket.
- If you can see coolant around the inlet manifold.
- If the engine isn't running smoothly.
If your vehicle is suffering from any of these, then it could well be your inlet manifold gasket that has worn down or failed. If this is the case, then our team would be happy to help, just give us a call.

An Extraordinary Adventure of Discovery and Exploration
Recovering, Conserving and Protecting Tonga's lost Maritime History. A joint project of Tonga Blue Ltd and the people of the Kingdom of Tonga, supported by HRH Crown Prince Tupouto'a 'Ulukalala.
There are many shipwrecks in the waters surrounding the Kingdom of Tonga.
Some were simply wrecked and others were 'killed' by brave Tongan warriors, so long ago. Most have never been surveyed or investigated.
Many are yet to be re-discovered and lay hidden beneath the sea. Some may have had important parts removed. The age of these wrecks could date back to the 16th century and all are national treasures that are part of Tonga's rich maritime heritage and deserve to be managed.
Ultimately, Tonga Blue hopes to work with the Government to help establish a comprehensive 'heritage dive trail' and archeological displays of significant artefacts in the Tongan Cultural centre to boost tourism.


debugging linked docker containers when using docker-compose
 - Last Update :
 - Techknowledgy :
If you want to debug in Docker Compose, run the command Docker Compose Up using one of the two Docker Compose files as described in the previous section, and then attach using the appropriate Attach launch configuration. Launching directly using the normal launch configuration does not use Docker Compose.,To use Docker Compose in VS Code using the Docker extension, you should already be familiar with the basics of Docker Compose.,If you already have one or more Dockerfiles, you can add Docker Compose files by opening the Command Palette (⇧⌘P (Windows, Linux Ctrl+Shift+P)), and using the Docker: Add Docker Compose Files to Workspace command. Follow the prompts.,With the docker-compose files, you can now specify port mappings in the docker-compose files, rather than in the .json configuration files. For examples, see the Docker Compose documentation.
Configure the debugging port in docker-compose.debug.yml. This is set when you create the file, so you might not need to change it. In the example below, port 9229 is used for debugging on both the host and the container.
 version: '3.4'
 services:
 node - hello:
 image: node - hello
 build: .
 environment:
 NODE_ENV: development
 ports:
 -3000 -
 9229: 9229
 command: node--inspect = 0.0 .0 .0: 9229 . / bin / www
Here's an example that shows the Node.js launch configuration - Attach:
 "configurations": [{
 "type": "node",
 "request": "attach",
 "name": "Docker: Attach to Node",
 "remoteRoot": "/usr/src/app",
 "port": 9229 // Optional; otherwise inferred from the docker-compose.debug.yml.
 },
 // ...
 ]
You'll be prompted to choose the host machine (for example, localhost) and port you want to use for debugging. The default debugging port for Python is 5678. If you have multiple apps, you need to change the port for one of them, so that each app has a unique port. You can point to the right debugging port in the launch.json, and save the file. If you omit this, the port will be chosen automatically.
 "configurations": [{
 "name": "Python: Remote Attach",
 "type": "python",
 "request": "attach",
 "port": 5678,
 "host": "localhost",
 "pathMappings": [{
 "localRoot": "${workspaceFolder}",
 "remoteRoot": "/app"
 }]
 }
Right-click on the docker-compose.debug.yml file (example shown below) and choose Compose Up.
version: '3.4'
services:
 pythonsamplevscodedjangotutorial:
 image: pythonsamplevscodedjangotutorial
build:
 context: .
dockerfile: . / Dockerfile
command: ["sh", "-c", "pip install debugpy -t /tmp && python /tmp/debugpy --wait-for-client --listen 0.0.0.0:5678 manage.py runserver 0.0.0.0:8000 --nothreading --noreload"]
ports:
 -8000: 8000 -
 5678: 5678
VS Code tries to copy vsdbg from the host machine to the target container using a default path. You can also provide a path to an existing instance of vsdbg in the Attach configuration.
 "netCore": {
 "debuggerPath": "/remote_debugger/vsdbg"
 }
To skip this step, specify the container name in the Attach configuration in launch.json:
 "containerName": "Your ContainerName"
Suggestion : 2
For more info see the documentation
app1:
 command: python app.py
build: app1 /
 net: 'host'
app2:
 command: python app.py
build: app2 /
 net: 'host'
Additionally you should start your app1 in daemon mode and app2 in the foreground mode for debugging purposes:
docker - compose up - d app1
docker - compose run app2
Suggestion : 3

(.NET Core 3 and later only) Editing your code and refreshing the running site as described in this section is not enabled in the default templates in .NET Core >= 3.0. To enable it, add the NuGet package Microsoft.AspNetCore.Mvc.Razor.RuntimeCompilation. In Startup.cs, add a call to the extension method IMvcBuilder.AddRazorRuntimeCompilation to the code in the ConfigureServices method. You only need this enabled in DEBUG mode, so code it as follows:
public IWebHostEnvironment Env {
 get;
 set;
}
public void ConfigureServices(IServiceCollection services) {
 IMvcBuilder builder = services.AddRazorPages();
 #if DEBUG
 if (Env.IsDevelopment()) {
 builder.AddRazorRuntimeCompilation();
 }
 #endif
 // code omitted for brevity
}
Modify the Startup method as follows:
public Startup(IConfiguration configuration, IWebHostEnvironment webHostEnvironment) {
 Configuration = configuration;
 Env = webHostEnvironment;
}
Add the following HTML content to the end of the file, and then save the changes.

Hello from a Docker container!

In the output window, when the .NET build is finished and you see the following lines, switch back to your browser and refresh the page:
Now listening on: http: //*:80
 Application started.Press Ctrl + C to shut down.
Replace the contents of the OnGet method with the following code:
 ViewData["Message"] = "Your application description page from within a container";
Replace the contents of the Main method with the following code:
 System.Console.WriteLine("Hello, world!");
Suggestion : 4
The above command would both start your application with the debug profile enabled. Using the docker-compose.yml file above, this would start the services backend, db and phpmyadmin.,The core services of your application should not be assigned profiles so they will always be enabled and automatically started.,Services without a profiles attribute will always be enabled, i.e. in this case running docker compose up would only start backend and db.,This allows one to define additional services in a single docker-compose.yml file that should only be started in specific scenarios, e.g. for debugging or development tasks.

Description of Ceramic plunger mud pump:
A mud pump or drilling mud pump is used to circulate drilling mud on a drilling rig at high pressure.
The mud is circulated down through the drill string, and back through the annulus at high pressures.
Ceramic plunger mud pump for vertical double cylinder porcelain piston pump. It is divided into two kinds of quantitative and variable, is designed for pressure transmission mud type working medium designed. Quantitative pumps can be used in the spray dry noise tower and other pressure transmission field; variable sludge piston pump can be adapted to the filter press dehydration process to flow pressure changes.
The pump is hydraulically driven and consists of the electrical box part, the tank part, the power cylinder and the ceramic plunger in the overall structure (see figure).

Ensuring transaction-safety in Google App Engine
In last week's exciting post, I described an alternative to transactions that we use at Khan Academy, to ensure atomic datastore operations.
When used correctly, both the user-write lock and transactions are effective at avoiding a particular form of database corruption -- call it "data stomping." Data stomping happens when two requests try to modify the same datastore entity at the same time.
Request B does not see A's modifications, and its PUT overwrites A's PUT. A's modifications are entirely lost, even when they don't conflict with B's.
Transactions solve this problem by noticing the contention at request B's put() time, and forcing request B to retry from the beginning. Locks solve the problem by not allowing the time-overlap at all.
Note that for both techniques, you need to follow the GET - MODIFY - PUT idiom. It is an error -- a db stomping waiting to happen -- to do the GET outside the transaction/lock!
In this blog post, I describe the infrastructure we put in place at Khan Academy (which uses Google App Engine) to notice that error, and to make it easy to modify the source code to prevent it. We are making the source code available in two files:
- db_hooks.py: a generic db/ndb hooking infrastructure
- txn_safety.py: the specific hooks we use to detect and alert for transaction-safety violations
How do people use transactions (and locks) wrong?
The mistake people make is simple: they do the GET outside the transaction (or lock). Then when the transaction retries, it doesn't re-GET, so you end up with request B stomping out request A's changes.
You may think it's easy to remember to always do your GET's inside a transaction, but there are many ways to get this wrong:
- You do the PUT in a function that's far removed from the GET.
- You are given an entity and forget to run entity = entity.key.get() to "re-GET" inside the transaction
- There are multiple codepaths used to GET an object, and only some of them -- maybe the ones used 99% of the time, so everything seems mostly-fine -- are done inside the transaction
- The get() call gives a cached result
This last cause was a big problem for us: we would cache the entity corresponding to the current user, for efficiency. Then, whenever we wanted to update the current user, we'd do get_current_user().modify().put() inside a transaction, without realizing that get_current_user() was returning some cached entity that was fetched way before the transaction started.
The solution is pretty straightforward, once you realize there's a problem. The issue is finding out there's a problem in the first place, and then tracing through the code to find the problematic GET.
A Taxonomy of Data Stomping Errors
While the GET-outside-transaction error is the most common, there are many related types of data corruption. The infrastructure we put in place catches the following three types:
Doing the PUT inside a transaction or user-lock, but not the GET.
_USER_.transactional def seems_ok_but_is_not(uid): user_data = UserData.get_from_id(uid) # cached! user_data.points += 5 user_data.put()
The problem here is that get_from_user_id() gets the user-data entity from a cache. So even though it looks like you're doing the GET from within the transaction, you're actually (potentially) just seeing some object that was gotten much earlier in the request, outside this transaction.
- Totally unprotected stomping
Doing a GET - MODIFY - PUT entirely outside a transaction or user-lock.
def badfunc(user_data): user_data_again = db.get(user_data.key()) user_data_again.points += 5 user_data_again.put()
- Internal stomping
Doing two nested (or interleaved) GET - MODIFY - PUT's inside a single transaction/lock.
_USER_.transactional def _internal_fn(uid): user_data1 = get_user(uid) user_data1.points += 5 user_data1.put() _USER_.transactional def public_fn(uid): user_data2 = get_user(uid) user_data2.points += 10 _internal_fn(uid) user_data2.put()
The problem here is that user_data1 and user_data2 are totally different python objects. When we do the user_data2.put(), it totally overwrites the change made in user_data1. This is the classical db-stomping problem, but within a single request!
How To Use It
To get the benefits of transaction-safety checking, you must annotate a db/ndb model with a decorator saying what method you use to guarantee safe put()'s:
- _USER_() -- super rare!
- _USER_() -- commonly for polymodels and utility classes
- _USER_() -- for (Local)StructuredProperty models
- _USER_() -- easiest to use correctly (no need for transactions)
- _USER_() -- you put get-modify-put in a transaction
- _USER_(lockid_fn) -- you put get-modify-put in a user write lock
- _USER_() -- appengine lets you schedule cron jobs; if an entity is only accessed via a cron job, we know two requests will never access that entity at the same time
- _USER_() -- for legacy code
- _USER_() -- ditto
These instruct the transaction-safety system what kinds of violations to look for. There is much more documentation of each choice at the bottom of txn_safety.py. Note that _USER_ takes an argument: that should a be a function that takes an entity and returns the lock_id for that entity. For instance, if the lock is protecting a single user, the lock_id might be the user-id. This is necessary because a single lock can protect many different entities. Example:
_USER_.written_with_user_lock_model(lambda e: e.kaid) class UserVideo(db.Model): """A single user's interaction with a single video.""" user = db.UserProperty(indexed=True) kaid = db.StringProperty(indexed=True) # user's user-id video_key = object_property.KeyProperty(indexed=True)...
Second, you have to wrap your WSGI application in the transaction-safety middleware:
app = webapp2.WSGIApplication([...routes...]) app = txn_safety.TransactionSafetyMiddleware(app)
Then you just run your application. If there is a transaction-safety violation, the system will log it:
Did a put() of the same entity from two different python objects: . Other put: --- File "/api/internal/scratchpads.py", line 408, in update_user_scratchpad old_points, old_challenge_status, client_dt, time_taken) File "/api/internal/scratchpads.py", line 436, in add_actions_for_user_scratchpad finished=(progress == "complete")) File "/scratchpads/models.py", line 2775, in record_for_user_and_scratchpad scratchpad=scratchpad) File "/rewards/triggers.py", line 119, in update_with_triggers_no_put user_data, possible_badges, dry_run=dry_run, **kwargs) File "/rewards/util_rewards.py", line 158, in maybe_award_badges_no_put badge.award_to(user_data=user_data, **kwargs) File "/badges/cs_badges.py", line 450, in award_to user_data, self.name, self.description) File "/notifications/cs_notifications.py", line 201, in send_certificate_notifications coach.put() File "/user_models.py", line 4173, in put result = super(UserData, self).put(*args, **kwargs) --- Traceback (most recent call last): File "/api/internal/scratchpads.py", line 408, in update_user_scratchpad old_points, old_challenge_status, client_dt, time_taken) File "/api/internal/scratchpads.py", line 436, in add_actions_for_user_scratchpad finished=(progress == "complete")) File "/scratchpads/models.py", line 2777, in record_for_user_and_scratchpad user_data.put() File "/user_models.py", line 4173, in put result = super(UserData, self).put(*args, **kwargs) File "/db_hooks.py", line 55, in wrapper hook(model_or_models) File "/db_patching.py", line 613, in _examine_put_state _examine_tainted_put(entity) File "/db_patching.py", line 605, in _examine_tainted_put % (type(entity), tb))
This is an example of "internal stomping." If you had access to the source code, these tracebacks would be enough to tell you that record_for_user_and_scratchpad does a get() + put() of some user-data, and send_certificate_notifications does a nested get() + put() of the same user-data.
For power users, the source code documents functions like disable_user_write_lock_checking_in_test().
In the last blog post I mentioned that lock_util.py's fetch_under_user_write_lock could not be used at that time. Well, with the functionality in this blog post, it can be!, making it really easy to re-fetch an entity -- or not, as needed -- under the user write lock.
def update_points(user_data): with fetch_under_user_write_lock(user_data) as ud_again: ud_again.points += 5

The P4W project incorporates three lessons learned from previous, similar projects, such as Let's Connect which ran from 2012 to 2015. Let's Connect also took place in the Brainport region and shared P4W's objective of making labour markets more transparent. Several lessons were drawn from this project. These lessons include: first of all, the use of strong incentive systems to encourage individuals to disclose information on their skills (and other relevant attributes); second, the need for a "passport for work" to be selective and structured by nature in terms of its contents, to ensure efficient matching procedures; and third, to maintain acceptable levels of validity and reliability of data on skills (to prevent matching on false grounds). Finally, the passport should be part of a broader platform, linking relevant stakeholders (jobseekers, employers, educational institutes) within one accessible ecosystem.
There are also three barriers for the impact of artificial impact on labour to consider. The first barrier represents the lack of high-quality data about the intricacies of an occupation and its underlying skills. Second, forecasting models are limited due to the uncertainty around technology's impact on labor. Third, aggregate labour market data lacks regional specificity.
In P4W, the gamified assessment serves to promote the engagement levels of the target users (among which there are large differences in literacy levels). By incorporating principles of gaming through online role-playing games and neurogames, P4W seeks to differentiate itself from more classic, survey-based assessments by catering to motivational and incentive-based aspects of use. Previous research has shown a positive effect of gamification on these aspects. Furthermore, P4W heavily invests in psychometric validation of its tools, to ensure the reliability and validity of data for matching purposes. Finally, P4W is aiming for national as well as regional impact, through its contribution to the Dutch skills language CompetentNL.

The National Quantum & Dark Matter Road Trip is coming to a city or town near you. As a part of National Science Week, a team of scientists and science communicators will travel around Australia, delivering engaging presentations, hands-on activities, pub quizzes and more.
The nature of dark matter is one of the biggest mysteries of the Universe, and Australia is a key player in the quest to figure it out. Dark matter accounts for 84% of all the matter in the Universe, but we don't yet know what it is. Quantum technologies are crucial in the hunt for dark matter, and they're already used in smart phones and cars, medical imaging, manufacturing and navigation. But today's technologies capture only a small fraction of the potential of quantum physics.
Our road-trippers are looking forward to spreading their knowledge and enthusiasm of quantum and dark matter. They hope to inspire the next generation of scientists and engineers, and highlight the potential of quantum technologies and dark matter discovery for the future of our society.
We will be traveling around Victoria from 7 - 11 August, holding individual public events in different states and territories during National Science Week and travelling around Queensland from 21 - 25 August.
Beyond the visible Universe: the kingdom of the unknown and a place for vivid imagination - public lecture by Prof Celine Boehm We are very grateful to The University of Sydney for their support of this event. This is a free event but registration is required. This venue has an accessible building entrance and accessible lift. Arrive 6:30pm for tea/coffee; 7-8:15pm public lecture and Q&A
