This is Omar aljarrah a web developer it is nice to meet you, and I would like to introduce you my self who I am and what I am looking for in the future
, so I am a beginner at web developing, coding and all that stuff my major in the collage was translation thats why I have a good command in English or at leats
above the average but it did not meet my passion thats why I involved into ASAC to improve my skills in programming


Prep.:
The seeds are baked by placing a seed on top of a lit light bulb seems to work for me better than in a stove or any other. Seeds are crushed in a mortar and pestle to a very fine powder. Then seeds are mixed with baking soda and a bit of water. After placing the brown sludge over a lightbulb set in a lamp I waited. After the mix is completely dried I crush it again in the mortar and pestle. It is ready.
Setting and Mind Set:
Sitting in my room very anxious. This would be my second yopo attempt first attempt was ill prepared and gave me all the bads without the goods. I sat there with well prepared powder in a medium sized line breathed in and out and dove in. One nostril, Two nostrils. Oh god it burns. I run into the bathroom and calm myself down.
Experience:
T=+0:30
In the bathroom staring at myself in the mirror. My Shower is on to calm me. The pain is intense but not anything i can't handle.  I know that soon I will be vomiting. Correct, I am currently vomiting but the effects are starting to kick in so I really don't care my vomit actually looks neat in yopo vision and I'm staring at it.
T=+5:00
The effects are now full blown there are many colors and if I close my eyes I can see a spirograph spinning out of control. I decide to take a shower just to experiment it is very relaxing and to my surprise i notice all feelings have become simply feelings. It was like if I feel pain and I tell myself that it is all in my mind. All feelings did not feel good or bad they were just feelings. Moving around is also very easy.
T=+15:00
I'm done with my shower and lay down in my bed I feel very good and all effects are still the same. I turn on my Zen CD for some peace.
T=+30:00
The effects start to change. Now there are transparent planes All over my room. It looks like there are windows all over my room. Also my room is green.
T=+35:00
My ceiling is moving and there are transparent tentacles coming out of my ceiling light. There are also geometric patterns all over the ceiling they look very fancy.
T=+45:00
I look up at three dots on the ceiling and realize that this must be how people made up star constellations. These three dots make up a horses face but look nothing like a horse without the yopo.
T=+65:00
The effects are gone and I feel great I turn on family guy and have some good laughs.
All in all this was a great experience and I can't wait to try again with lime in the mix. A word of advice is when this stuff is in your nose don't breath in through your nose and blow the stuff out when it starts to take effect.

I had been coding a test problem the night before. Feeling pretty ready to give up. It didn't work. I spent hours retesting my code. I tried it in different browsers and test environments. I gave up for the night and had a restless sleep. My girlfriend got annoyed with me. I was not popular, even with myself.
The problem was that I needed to know the difference between a parameter and an argument. Getting confused about this is not fun.
A parameter is a way to get the data where it needs to go within a piece of code.  When you pass information into a parameter it becomes the passanger.
I worked this out by the ducky method. The ducky method is inspired by the rubber ducky method of talking to a rubber duck, but involves going outside and give the visiting ducks some rolled oats and tell them the problem.
I also worked out that it is not good to try to explain your programming problems to non-coding friends lol.
Fizzbuzz is an interview question for programmers. It's like the 'where do you see yourself in 5 years?' You better have an answer for it. You need to write a program to prove that you can program. The question is to replace multiples of 3 and 5 up to 100 with a silly word. It seems simple. I first thought of dynamically creating a times table in one list and then overlaying that list with the numbers 1- 100. Then asking a question: is a number is in the buzz list, replace it with buzz. Is the number is the fizz list, replace it with fizz. It felt like a Dr. Seuss book.
But in starting to work this out I remembered that modulo % aka the percent sign gives you what is called modulous congruence between two mumbers, ie there is no remainer. A way to visualise this is that it's like a tiled floor where all the tiles are square and fit perfectly without being cut. It doesn't matter what the size of the tile is or the room, it is their congruence that matters. Tilers need Fizzbuzz.
This is of course, the actual correct way to do it. I coded it and check my answer against the solution and they were nearly identical. This made me feel smart.
What I learned is that having a visualisation of the data that is both vivid and applicable to the problem is super helpful for me to search the solution space. Thinking again of a the tiled floor analogy. My original proposed solution would be equivalent to having to draw the floor for each number between 1 - 100. That would work, and it is an artists solution (see variations of open and incomplete cubes by Sol Lewitt), but it is not an elegant one.

This is the third post in a series about managing your Ruby Toolchain. Expect at least one more after this. You can also read:
Pieces and Parts: Managing Your Ruby ToolChain(part 1)
Managing Your Ruby Toolchain Part 2: The Package Repo Rant
Why I rant about package repositories: Static software without a repository is the pebble that becomes an avalanche. So many undesirable behaviors stem from no one owning the package collection. Read the rant if you want details. This is a practical discussion, although I’m not telling you what to do. I’m just telling you what I’ve done and what I’ve seen over the course of my career. There are many ways to solve this problem. Do what works for you.
This post grew so much that there is one more after it that specifically deals with some toolchaining tools and ideas as well as a few anecdotes on how I’ve dealt with some of these challenges in the past.
Today we’re going to talk about:
Tarball Orphans vs Artifacts vs Inbetweeners
The Internet
An Approach to Repositories
Packaging Tarballs
Ruby Management
Ruby Toolchain Management
What do I mean when I rant about tarballs?
What is exempt from my ranting wrath? Custom code that you might tar up instead of jar/ear/war. Anything that changes often shouldn’t be in our static package repository. Those are places to keep long term, install-once per server software.
When I talk about tarballs, I mean tumbleweed off the internet. When I refer to compiled code I’ll use the word artifact. What’s an artifact? It might be a jar file you bundle with your deployed code. It might be a war file. It might be a tar of ruby code Or database artifacts. Anything that’s your stuff, we don’t put that into package repositories. We put it into artifact repositories like Artifactory and Nexus. People also use S3 storage to store and retrieve artifacts.
Some things may not be easily categorized. Newer products get frequent updates that may require frequent patches or deployments. For example, I worked with a team that implemented Basho’s Riak which they updated frequently and ended up engaged in a disagreement with Ops on how often they could update it. The ops team wanted to restrict it to quarterly and the devs wanted much more frequently. This sort of management requires a custom solution that may be package-based or not.
If your infrastructure has free access to the internet, that’s awesome. Many infrastructures have limited or no access to the internet. Often the reasons for this seem silly. But sometimes you can’t fight city hall, or you can but you need to save your fights for the life or death kind. Your servers don’t need the internet to survive. Or they should not.
Eventually you will find yourself needing stuff from the Internet. In order to work within restrictions, you can set up a Bastion host or AWS VPC infrastructure that can call out to the internet in order to create private mirrors of any repositories you need. You can follow the slightly more difficult path of setting up an internal server that contains your repos that you need to sync in a way that doesn’t have direct access to the internet.
Internet as Troublemaker
Internet access brings its own set of problems as well. If you aren’t specific about package versions, with every server provision you could have slightly different versions of things installed. This is a problem because it can cause erratic behavior across your infrastructure. If you have 1000 nodes built over the course of six months, each build wave can introduce incremental differences. When you control the packages in your internal repos, you exert a stabilizing effect, which is a good way to control your system without making it brittle.
Even if sloppy package management doesn’t actually cause issues, it will be a suspect in any intermittent, mysterious problems. Picture an outage conference bridge including execs. Now envision yourself explaining to them how this mismatch isn’t a problem. Can you envision any explanation that doesn’t make you sound like a dolt?
Example: A few years ago JBoss 5 shipped with a bug that was a major performance blocker but difficult to track down. It was later fixed in a minor patch release. Imagine having a JBoss package block that just says package "jboss" {action :install}
and using an internet repo to install it. 6 months later you provision 100 servers from your trusty internet repo and over your peak season, the bug triggers but everything is weird because it’s only a problem on some servers. Imagine tracking this down.  If you’re a sysadmin and you think this isn’t a big deal, may we never be responsible for the same infrastructure.
Be Conservative. As a rule it’s ok to use external signed key repositories for your base OS packages as those shouldn’t change. Tread carefully even with patch/update servers to ensure homogenous installs and any packages acquired from other internet repos (like EPEL) should be installed with explicit versions.
Adopt Orphans Don’t let Internet-sourced software roam around your infrastructure unsupervised. If you need a package from the internet, it should be easy enough to download and insert into your custom repository. There are several tools for managing repositories. For Enterprise Linux, Cobbler, the provisioning and infrastructure management tool has repository management and mirroring. My new favorite thing for this though is a tool called Pulp, an open source project by Red Hat. If you prefer simplicity, you can just install a web proxy and use a command line tool like createrepo
to manage your yum repos.
Don’t assume I can talk to the Internet. When it comes to configuration management tools, I find it in bad taste to write a module or cookbook intended for the community with an Internet dependency. If you have to write one, label the dependency in large font.
OS Packages
If you’re going to set up repositories, consider a collection like this list.
Base - base EL install repo - This is generally straight up ISO content
Patch - repository containing patches
EPEL - EL Extras repo mirror
Custom - repository containing all the custom packages I need that I’ve either crafted myself or downloaded
Purity of Purpose: Always keep your base and patch repos pure. Don’t let people just dump random packages into a Base OS collection. You’ll never know what was supposed to be there and what was added later.
Prioritization and Specificity: If you have two versions of a package in different repos, either be specific when installing or configure a priority for each repo.
Rubygems
This is where you get/put your gems. Gem is the package manager for Rubygems. You either need to connect to the internet to get all of these things or you need internal package repos/mirrors. See this blog post by David Moulton for how easy it is to set up a rubygems repo.
Artifacts
This is where your deployment artifacts, jar, war, ear files should be contained; a tool where it’s easy to retreive them programmatically. I have seen people use Nexus, Artifactory and even S3 to store artifacts. If you’re not a java shop, you may not need something this complex. My major experience is with Java shops.
YMMV
There are many ways to craft your infrastructure. Having package repositories is an advantage because they make it really obvious to everyone in your organization where to look for software and where they should put software they need.
The important thing to keep in mind here is that, especially if you’re in the Enterprise, you aren’t designing for yourself or just one team. This will balloon out to include dev teams using your tools. In order to deploy their app, the devs will test using VMs provisioned by your infrastructure and they should be taking advantage of your beautiful repos to deposit their extra software packages. Your team may even be administering the VM infrastructure.
A major goal to strive for is for all VMs and servers to be provisioned the same way in all environments, desktop to production. You make this easiest and more likely to happen when you make it easy to interact with software repositories. If it’s not easy, other teams will “figure something out” which will likely outrage you when you discover it.
Avoid Compiling From Source
Believe me when I say that you do not want to compile Ruby from scratch every time you build a server. The more automation achievements you unlock, the easier it becomes to use ephemeral VMs. In Dev, people should be popping up and killing VMs all the time. If it takes 10 minutes to build a server, they won’t be doing this, dev VMs will have major cruft buildup and dismay will ensue when people realize they can’t actually reproduce their dev VM.
Turning a Tarball into a Package
How do you get packages for your repos when all you have is a pile of tarballs? If you’re brilliant, write a package spec for it. If you’re like the rest of us, you use FPM. Even if you are in a situation where you can’t have a package repo, you can at least create and store packages which will speed up installation and simplify implementation.
FPM: Learn it, love it, live it.
Ruby Source
1.8.7 is EOL
First, on the topic of existing packages, as announced in October of 2011, Ruby 1.8.7 is officially end of life and won’t even get security updates after June 2013. Just say no to the supplied 1.8.7 packages on your Enterprise Linux(EL) and the one that comes installed with OSX. No really, never touch it. If you’re using it, start seriously considering how to move on.
System Ruby
Whatever else you’re doing, your servers will all want a system Ruby. It’s possible to get along without this(see omnibus in subsequent sections), but especially in dev, people will be shocked and dismayed when there’s no easily accessible Ruby. So get you some Ruby, not from the ancient EL repos, but get the source tarball from Ruby-Lang.org.
Why do I tell you this obvious thing? We had the brilliant idea of switching out our compile-every-time system ruby install with just using the embedded Ruby that ships with Chef client. Never do this. The trouble is that your Ruby install is not just an executable, but a name space for installing gems and related software. This is is why Chef ships in an omnibus in the first place: to avoid dependency hell and version conflicts. The other problem with this idea is that you are still lacking a system Ruby. You either have symlink to the Ruby executable or people have to know where to look for. So install a system Ruby independent of any other software.
Next make a Ruby RPM. RPMs are hard. Luckily Ian Meyer is watching out for us and has a defined, working spec from which to build an RPM. I’ve made this Ruby RPM for two different clients and it compiled without a hitch.
Once you create an RPM, put it into your custom package repo so that you can yum install ruby-1.9.3 or install it via cookbook later.
I repeat this series of steps for the Rubygems tarball, except using FPM to package it. Then they go in my custom repo where the custom repo has a higher priority than my base repo and my recipe just has a package block to install Ruby and Rubygems. It takes about 30 seconds instead of the 5 minutes it takes to compile Ruby from scratch.
If you use Ubuntu, well, they are cooler than EL and have Ruby-1.9.3 packages.
Where Do We Go From Here?
An important part of toolchaining is maintaining control of the supply chain. The way we do that is by creating space for packages and actively managing that space. It should be freely accessible to both deposit and receive software. Don’t manage things by locking people out, but by making it easy to use and providing guidelines for usage. Most people want to do the right thing. When you make the right thing easy to do, more people will do it.

'Bagel Boss Guy' Chris Morgan hospitalized after apparent stroke
by Kenneth Garger“Bagel Boss Guy” Chris Morgan has been hospitalized after suffering an apparent stroke, his manager revealed Wednesday.
Morgan, 45, suffered the medical emergency on Monday outside of a Long Island deli where he parks the minivan that he lives in, said Bill Shannon.
Shannon, who just learned of the health scare on Wednesday, said it appears Morgan lost feeling on the left side of his body.
‘BAGEL BOSS’ GETS CUFFED, TAKEN TO HOSPITAL FOR EVALUATION: REPORT
But when he visited his client at Southside Hospital in Bayshore, Shannon said Morgan communicated with him by moving his right arm.
“I went in there and I said ‘hello’ to him,” Shannon said. “I said ‘I’m sorry this happened’ to him.”
“He was definitely aware I was there and responded with his hand.”
Morgan, though, wasn’t able to open his eyes or talk during the visit.
Shannon was able to alert Morgan’s family, who showed up to the hospital late Wednesday.
The manager also said Morgan suffers from diabetes — though it’s unclear if that contributed to the medical episode.
A GoFundMe page has been set up to help cover the cost of Morgan’s recovery.

Birbal immediately smiled and went up to Akbar. He announced the answer; he said there were twenty-one thousand, five hundred and twenty-three crows in the city. When asked how he knew the answer, Birbal replied, “Ask your men to count the number of crows. If there are more, then the relatives of the crows must be visiting them from nearby cities. If there are fewer, then the crows from our city must be visiting their relatives who live outside the city.” Pleased with the answer, Akbar presented Birbal with a ruby and pearl chain.

Quantification in Logic Tensor Networks
Base quantification
The logical quantifiers, namely \(\forall\) and \(\exists\), are implemented in LTN using fuzzy aggregators. An
example of fuzzy aggregator is the mean. The ltn.fuzzy_ops
module contains the implementation
of the most common fuzzy aggregators.
In the note regarding the LTN broadcasting, we have seen that the output of logical predicates, for example \(P(x, y)\), is organized in a tensor where the dimensions are related with the free variables appearing in the predicate. In the case of the atomic formula \(P(x, y)\), the result is a tensor \(\mathbf{out} \in [0., 1.]^{m \times n}\), where \(m\) is the number of individuals of variable \(x\), while \(n\) is the number of individuals of variable \(y\).
Notice that:
the tensor \(\mathbf{out}\) has two dimensions because the atomic formula \(P(x, y)\) has two free variables, namely \(x\) and \(y\);
variable \(x\) has been placed on the first dimension, while variable \(y\) in the second dimension, according to their order of appearance in the atomic formula;
the output of the predicate is wrapped inside an LTN object where the value attribute contains the tensor \(\mathbf{out}\), while the free_vars attribute contains the list [‘x’, ‘y’].
Now, we can extend this example with the formula: \(\forall x P(x, y)\). In order to compute the result of this formula, LTNtorch must compute the result of the atomic formula \(P(x, y)\) first, and then apply a fuzzy aggregator to this result for performing the desired quantification on variable \(x\).
We know that the output of \(P(x, y)\) is the tensor \(\mathbf{out} \in [0., 1.]^{m \times n}\), and that the first dimension is related to variable \(x\) while second dimension to variable \(y\). In order to perform the quantification of \(P(x, y)\) on variable \(x\), LTNtorch simply performs an aggregation of tensor \(\mathbf{out}\) on the first dimension. Let us assume that the selected fuzzy aggregator for \(\forall\) is the mean. LTNtorch simply computes torch.mean(out, dim=0), where out is the tensor \(\mathbf{out}\) and dim=0 means that we aggregate on the first dimension of out, namely the dimension related to variable \(x\).
After the application of the quantifier, a new LTN object is created. The attribute value will contain the result of \(\forall x P(x, y)\), that will be the tensor \(\mathbf{out}' \in [0., 1.]^n\), while the attribute free_vars will contain the list [‘y’].
Notice that:
the result has one less dimension within respect to the result of \(P(x, y)\). This is due to the fact that we have aggregated one of the two dimensions, namely the dimension of \(x\). The only dimension left is the dimension related with \(y\), and it is for this reason that \(\mathbf{out}\) is now a vector in \([0., 1.]^n\);
the attribute free_vars contains now only variable \(y\). This is due to the fact that variable \(x\) is not free anymore since it has been quantified by \(\forall\).
Finally, notice that if the formula would have been \(\forall x \forall y P(x, y)\), the quantification would have been torch.mean(out, dim=(0,1)), namely both dimensions of \(\mathbf{out}\) would have been aggregated. Also, the output would have been a scalar in \([0., 1.]\) and no more free variables would have been in the formula, since both variables have been quantified.
Diagonal quantification
Given 2 (or more) variables, there are scenarios where one wants to express statements about specific pairs (or tuples) of values only, instead of all the possible combinations of values of the variables. This is allowed in LTN thanks to the concept of diagonal quantification.
To make the concept clear, let us make a simple example. Suppose that we have the formula \(\forall x \forall y P(x, y)\). Suppose also that variables \(x\) and \(y\) have the same number of individuals, and that this number is \(n\).
With the usual LTN broadcasting, the predicate \(P(x, y)\) is computed on all the possible combinations of individuals of \(x\) and \(y\). In other words, the result of \(P(x, y)\) would be a tensor \(\mathbf{out} \in [0., 1.]^{n \times n}\). Then, after the quantification on both \(x\) and \(y\), we obtain a scalar in \([0., 1.]\).
With diagonal quantification (\(\forall Diag(x, y) P(x, y)\)), instead, predicate \(P(x, y)\) is computed only on the tuples \((x_i, y_i)\), where \(x_i\) is the \(i_{th}\) individual of \(x\), while \(y_i\) is the \(i_{th}\) individual of \(y\). In other words, the output would be a tensor \(\mathbf{out} \in [0., 1.]^n\). Notice that the output has one single dimension since the predicate has been computed on \(n\) tuples only, namely the tuples created constructing a one-to-one correspondence between the individuals of \(x\) and the individuals \(y\). At the end, after the quantification, a scalar is obtained like in the case with the previous case.
The advantages of diagonal quantification are mani-fold:
it is a way to disable the LTN broadcasting. Even if it has been designed to work with quantified statements, it could serve as a way to temporarily disable the LTN broadcasting when computing some formulas. In fact, sometimes it is not necessary to compute a predicate on all the possible combinations of individuals of the variables in input;
it is more efficient compared to the usual quantification since it allows to avoid to compute a predicate on all the possible combinations of individuals of the variables appearing in the predicate;
it is useful when dealing with variables which represent machine learning examples. In many tasks, the dataset comes with some labelled examples. One variable could contain the examples, while another variable could contain the labels of the examples. With diagonal quantification we are able to force LTNtorch to use these variables with a one-to-one correspondence. This allows to avoid to compute formulas on combination of individuals which do not make any sense, for example a data sample labelled with a wrong label.
Notice that diagonal quantification expects the variables to have the same number of individuals, since a one-to-one correspondence has to be created.
In order to use diagonal quantification in LTNtorch, it is possible to use ltn.core.diag()
.
Guarded quantification
In some cases, it could be useful to quantify formulas only on variables’ individuals which satisfy a given condition. This is allowed in LTN by using the guarded quantification.
To make the concept clear, let us make a simple example. Suppose that we have a binary predicate \(P(a, b)\). Then, we have two variables, \(x\) and \(y\), containing sequences of points in \(\mathbb{R}^2\). Specifically, \(\mathcal{G}(x) \in \mathbb{R}^{m_1 \times 2}\) and \(\mathcal{G}(y) \in \mathbb{R}^{m_2 \times 2}\). So, \(x\) contains \(m_1\) points, while \(m_2\) contains \(m_2\) points.
We have already seen that LTN allows to compute the formula: \(\forall x \forall y P(x, y)\). Also, we know that LTNtorch firstly computes \(P(x, y)\) and then aggregates on the dimensions specified by the quantified variables.
Suppose now that we want to compute the same formula \(\forall x \forall y P(x, y)\) but quantifying only on the pairs of points whose distance is lower than a certain threshold. We represent this threshold with the constant \(th\). In Real Logic, it is possible to formalize this statement as \(\forall x \forall y : (dist(x, y) < th) \text{ } P(x, y)\), where \(dist\) is a function which computes the Euclidean distance between two points in \(\mathbb{R}^2\).
In order to compute this formula, LTNtorch follows this procedure:
it computes the result of the atomic formula \(P(x, y)\), which is a tensor \(\mathbf{out} \in [0., 1.]^{m_1 \times m_2}\);
it masks the truth values in the tensor \(\mathbf{out}\) which do not satisfy the given condition (\(dist(x, y) < th\));
it aggregates the tensor \(mathbf{out}\) on both dimensions, since both variables have been quantified. In this aggregation, the truth values masked by the previous step are not considered. Since both variables have been quantified, the result is a scalar in \([0, 1]\).
For applying guarded quantification in LTNtorch, see ltn.core.Quantifier
. In particular, see mask_fn
and cond_vars parameters.

Templates are markup (html, ejs, etc) that Nxus modules can use to render a UX. The Templater module provides a common API for defining and accessing templates. Specifically, you can use partials and templates defined by other modules, meaning you write less code for common components.
> npm install @nxus/templater --save
Templater supports EJS and HTML as default template types. If you'd like to add in additional parsers, check out the @nxus/renderer documentation.
All templates share a single namespace, so its a good idea to add a prefix to your template names to avoid conflicts. For example mymodule-mytemplate
.
There are three types of templates you can register.
If you would like to register a single template, you can use the template provider and specify a file:
app.get('templater').template('path/to/some/file.ejs')
Based on the filename, the template will be given the name file
and rendered using the EJS renderer.
Optionally, you can specify another template to wrap the output (for partial style templates).
app.get('templater').template('path/to/some/file.ejs', 'page')
Alternatively, if you have a folder with all your templates, you can add them all using templateDir
.
For example, given the following directory structure:
- /templates
|- my-template.ejs
Templater will expose my-template
as a new template.
app.get('templater').templateDir('path/to/some/dir/')
Each template will be processed using the template
function above. You can also specify a wrapper template.
app.get('templater').templateDir('path/to/some/dir/', 'page')
You can also pass in a handler method instead of a file path. Templater expects that this handler returns a string with the rendered content, or a Promise that resolves to a string.
The handler will be passed in the name of the template requested, as well as any render options specified.
var handler = function(args, name) {
return "<html>.....";
}
app.get('templater').templateFunction('default', handler)
let opts = {content: "some content"}
app.get('templater').render('default', opts).then((content) => {
console.log('rendered content', content)
})
If you want to specify a different wrapper template than was originally set, you can add a template
key to the opts object.
opts.template = 'new-template'
app.get('templater').render('partial-template', opts).then((content) => {
console.log('rendered complete content', content)l
})
In place of EJS' include
function for rendering sub-templates, you can use the render
function to use a templater-registered template name within a template:
<%- render('app-nav`) %>
or with specific options
<%- render('app-nav', navItems) %>
Modules can provide additional context options to be available to templates. :
app.get('templater').on('renderContext', () => {return {username: 'Steve'}})
The event handler is passed the original template name and args, so if req
or other is provided it is available to you, or if you want to only provide context for some templates, but you do not need to return the whole modified args:
app.get('templater').on('renderContext', (args, name) => {return {username: args.req ? args.req.user : '' }})
Templater will also fire a template specific event
app.get('templater').on('renderContext.my-template', () => {return {username: 'Steve'}})
Values that are arrays are concated rather than overwritten, so that for instance scripts
can collect script URLs from many modules:
app.get('templater').on('renderContext', () => {return {scripts: ['/url/script.js']}})
app.get('templater').on('renderContext', () => {return {scripts: ['/url/other.js']}})
Will result in scripts
containing an array with both these values. The list will be filtered to only have unique values, so you can specify scripts in dependency order and not worry if other modules are asking for the same common js files repeatedly. The default set of templates provided by this module include rendering of this scripts
variable automatically.
Templater provides a template layer, built on top of the Nxus Renderer

Structs
The following structs are available globally.
-
A sorted collection of comparable elements; also known as a multiset.
SortedBag
is like aSortedSet
except it can contain multiple members that are equal to each other. Lookup, insertion and removal of any element has logarithmic complexity.SortedBag
stores duplicate elements in their entirety; it doesn’t just count multiplicities. This is an important feature when equal elements can be distinguished by identity comparison or some other means. (If you’re OK with just counting duplicates, use aMap
or aDictionary
with the multiplicity as the value.)SortedBag
is a struct with copy-on-write value semantics, like Swift’s standard collection types. It uses an in-memory b-tree for element storage, whose individual nodes may be shared with other sorted sets or bags. Mutating a bag whose storage is (partially or completely) shared requires copying of only O(log(count
)) elements. (Thus, mutation of sharedSortedBag
s may be cheaper than ordinarySet
s, which need to copy all elements.)Set operations on sorted bags (such as taking the union, intersection or difference) can take as little as O(log(n)) time if the elements in the input bags aren’t too interleaved.

List
can often be much faster than processing individual elements one by one. For example, splitting a list or concatenating two lists can be done in O(log(n)) time.See moreNote
List
implements all formal requirements ofCollectionType
, but it violates the semantic requirement that indexing has O(1) complexity: subscripting aList
costsO(log(count))
, since it requires an offset lookup in the B-tree. However, B-trees for typical element sizes and counts are extremely shallow (less than 5 levels for a billion elements), so with practical element counts, offset lookup typically behaves more likeO(1)

Dictionary
’s best-case O(1) (worst-case O(n)) implementations for the same operations. To make up for being typically slower,Map
always keeps its elements in a well-defined order.While independently looking up individual elements takes O(log(n)) time, batch operations on lots of elements often complete faster than you might expect. For example, iterating over a

Computer & Programming¶
Important
Now I mainly use Python, and I rarely use Pascal/C++/C# that I learned before. I also know HTML/CSS and a little Javascript, otherwise I wouldn't have been able to write this site.
If you consider LaTeX a programming language, I'm a heavy LaTeX user too. See my published book on how to use LaTeX (Github repo: wklchris/Note-by-LaTeX).
Yes, that's right, of course. Programming has been my biggest passion for a long time, and I'm happy to see that. Here are my representative Github projects, you can also access my Github home page via the Github icon in the top right corner of the page (thanks lepture/github-cards for repo cards rendering):
Around 2000 (at the age of about 6), I was introduced to computers. I was very fortunate to be exposed to and interested in computers at a very young age, especially against the backdrop of the slow penetration of computers in China at that time.
In 2004, I started learning programming. Pascal was the first language I came across in my life, learning it in a Delphi environment.
Around 2008, I went to Wuhan, Hubei to participate in the provincial Olympiad in Informatics, but I only got a city-level third prize.
During 2012-2014, I enrolled Visual Basic, C++ courses in Tongji. I also self-learned data structures and algorithms during that time.
Around 2015, I learned about Github and register an account.
I began to share my LaTeX learning notes on Github (wklchris/Note-by-LaTeX), and compiled them into a book and publish them in 2020.
I built my personal website at that time and learned HTML/CSS/Javascript by building the website.
I self-learned Python 3 and quickly fell in love with its simplicity and ease of use.
In 2018, I took advanced algorithm courses and a D3.js visualization course.

[Erowid Note: This report mentions a 'mescaline pill' obtained at a rave; it is very, very unlikely to be mescaline, which is generally unavailable in the U.S. street drug market. We've marked the substance as 'unknown', but it will show up in searches for Mescaline as well in order to highlight this problem.]
I used to really be into raves. I enjoyed the atmosphere. A bunch of people getting really high and enjoying each others company. I used to think they were great untill an experience I had in New Orleans one year.
My girlfriend (Danielle), Tuck, Robbie, and myself decided we were going to go see DJ Irene. Well it was Tucks first rave and he had never rolled on X before either. Danielle and I had been up for about 3 or 4 days on Meth before the trip.  The entire way down there all 4 of us smoked Meth out of a hollowed out light bulb. It was about a 6 hour drive. Needless to say it was a very talkative 6 hours. We arrived in N.O. and smoked a blunt between us before we got to the State Palace.
When we walked in I was very energized and happy. I was dancing and talking to random people. I was planning on taking 3 X pills. Danielle was just going to take one. Robbie was going to do whatever was available, and Tuck was going to take an X pill for the first time. Well I ran into my friend, we will call him Matt. I asked him if he could get any X.  Well LSD is probably my favorite drug. I like Mescalin but didn't think that a rave was necessarily a good environment to do it in. I believe its more of a spiritual thing, best enjoyed in nature.
Well I decided I was going to do acid. I told him I just wanted 10 hits of 'Cid' for now. I gave him my money and he ran off. 10 minutes later I ran into him. We ducked off in the cut and he handed me 10 small squares of tinfoil. I found Robbie and gave him his hit. I gave Tuck 2 but he was going to save them for the next day. I ran to the bathroom and unrapped the tinfoil and put 1 hit under my tongue and 1 on top. I then found matt again and then told him I wanted two X pills, one for Danielle, and one for Tuck.
Well 15 minutes later the trip started to kick in. It was coming on like a normal acid trip except for being all happy and giggly. I was somewhat paranoid. Matt had the money and it seemed like he had been gone for like an hour. In reality it was only 20 minutes. I was wigging out. Finally Tuck and Danielle calmed me down. I was starting to get REALLY good visuals, probably some of the best I have had before. I loved it. Finally I met up with Matt in the laser tag room and he gave me the pills.  The were called blue torches. I gave one to tuck and one to Danielle. They both took them. From that point on it was somewhat of a normal rave.
Some guy kept following me around wanting to fill my water bottle up. It freaked me out. I heard him tell Robbie, 'That dudes trippin hard, take care of him.' I didn't really realize how hard I was tripping until he said that. At that point I decided Robbie and I should go to the bathroom and look in the mirror. I love to do that. While we were doing that some guy I've never seen came in and said 'Yall good on Tabs.' I had alot of money so I asked him what he had. He said he had 'blue torches' and 'mescalin' pills. Without thinking I bought one of each.
Robbie and I walked out of the bathroom and I started freakin out. I said to Robbie 'Why did I buy these, I am so wasted already I don't need this.' Robbie just shook his head and laughed. I went and found Danielle and asked her what I should do. She was kinda upset with me. I didn't know whether or not to take them.  I was like, 'yeah I guess you're right.' Next thing I know my friend Ronnie comes up. He was trippin too. I said, 'Ronnie I just bought these pills, should I take them or not?'  Without hesitating I swallowed both of them. Danielle just shook her head.
Well 20 minutes later a big group of us were just chillin against a wall in the laser tag room. I started to feel the roll come on. I was excited at first. Then something started to happen. I started to feel like I wasn't in my body. Not like I was having an out of body experience just some what disociated. I didn't really like it. I was telling danielle I couldn't feel my body anymore. She started getting worried. Well next thing I know I feel like I'm about to pass out. I did. Well what happened next felt like forever.
I went to this state where I didn't know that I was alive. I didn't know what being alive was. I didn't know what a human being was. I was some sort of entity floating around in the large area. I then woke up. It felt like eternity, but It was only a couple of minutes everyone later told me. When I awoke 2 people were in my face asking me if I was okay. I noticed some people huddled over laughing at something else. 1000 thoughts literaly came into my mind at one time. It was overwhelming.
The most predominant thought that I had was, 'The concept of raves is rediculous. A bunch of modern day hippies, burnouts, take as many hallucinogenic drugs as possible and huddle in corners listening to repetitive electronic music.' I didn't like it. Everything was moving so hard and uncontrollable. These were the strongest visuals I have ever had. The floor was shooting up into spikes and I thought there were bugs flying around everywhere but I realized it was tracers off of peoples fingernails, glowsticks, hair, clothes, everything.
All of this happened in a few seconds. Next thing I know I stand up screaming uncontrollably. Loud, scared sreaming. Ronnie grabbed me and was going to carry me outside. I kept telling him 'Ronnie if I close my eyes I go to a world where I don't know whats going on and I forget what a human being is, and If I open them everything is moving so uncontrollably and shooting at me, I don't know what to do.' I kept closing and opening my eyes repeatedly trying to stop both things from happening. He said 'you are just trippin man, It will be okay.'
Well when I got outside I couldn't tell if it was day or night. The sky was purple and the buildings where changing from Light to Dark with multiple colors moving all over them like little demons crawling around. It was beautiful now that I look back at it.  My first thought was, 'Why is Jerry reproducing? He is such a burnout. We don't need anymore Jerry's.' I was shaking. I didn't know what to do. Next thing I know Danielle comes running out saying 'Chris I lost my engagement ring.' I was so wasted I said, 'I don't care, go look for it, if you don't find it we will be okay.' She ran inside and Tuck and Robbie came out. Ronnie went back with Danielle to help find the ring. Tuck and Robbie stayed with me.
We got into my car. Needless to say I could'nt drive. Tuck was the only one who could drive a standard. He said he was great to drive.
[Erowid Note: Driving while intoxicated or tripping is dangerous and irresponsible because it endangers other people. Don't do it!]
Well Danielle comes out and she found the ring, Thank God. I don't know how she did it though.    He looked like he was on xanax or something.   Well we started going down the road and I started chillin out alot.
I kept telling them what had happened to me. OVER AND OVER. Next thing I know I look up at the sky and look at the clouds. I see these tubes in one of the clouds that are wiggling around like worms. I then started asking everyone, 'Why are there tubes in the clouds? Do you guys see those tubes? What do you think those are there for?' Tuck then reminded me that I was tripping. I completely forgot I had taken anything. I looked at the tubes and somehow felt conected. One of the tubes slowly came down and went directly into my face. I then 'thought' we stopped for gas and some lady was screaming at me to pay before I pump. Then the tube left and I asked everyone if we stopped for gas. They all told me we hadn't.
Well I just sat there lost in my own mind and then had a strong urge to smoke pot. I then said, 'Roach blunt smoke lets.' Everyone started laughing. I then said, 'Laugh what at are Yall?' I then realized I was confusing my words. I kept talking like that for 30 minutes. That has never happened to me. It was crazy but It started bothering me. Finally I was able to talk after we smoked some weed. After that we stopped to get gas. I tried to then pump first and then the lady accused me of stealing gas, and told me I had to pay first. It was exactly what happened to me when the tube came down. I still don't know if maybe my mind just got switched up and turned around and I thought I saw the future, or if I actually did.
Well after that I started coming down and was able to comprehend life better. I still had pretty strong visuals but I was okay. We got back to shreveport and It was about 8 in the morning. We went to a place called wallace lake dam. Tuck then took his first 2 hits of acid. We hung out there for a while. Then I decided we needed some weed. I went and bought a blunt from a friend of ours. We then went to a park. I parked my car. I rolled the blunt and we all sat there and smoked it while danielle was smoking meth. She thought she might have a drug test in a couple of weeks so she didn't smoke the weed.
Well runners would pass by my car. I had 5% tent on my windows so they couldn't see us, but I had them down enough to let smoke out. I guess some of the runners smelled it. Well I left my lights on so my car died. We had finished the blunt. Tuck had the roach in his cigarette pack with his hits of acid. I decided we were going to have to push my car so I could pop the clutch. Well when we started to do that, 2 cop cars pulled up. This is when things got really weird.
I don't remember how it started but the cops seperated us. He then searched us. They found Tucks blunt roach. They put him in the cop car. Mind you he is tripping on acid for the first time. I'm wigging out. He then told me to tell him what else I had on us. He didn't find anything on me, but my car was a mess. I told him there were some seeds and stems probably and that was all. I knew it wasn't. He then told me if he found anything else we were all going to jail. I told him there was a light bulb that we smoked meth out of. He told me to get it. When I was in there I grabbed the bulb and slid a bag of weed in my sleeve. I gave it to him. Then I notice that they are looking through Tucks cigarette pack again. They find the Acid.
They started questioning him. I had 5 hits in my wallet at the time. They asked him were he got it. He pointed at his wrist band, because it said 'state palace' on it. They said, 'You got it from your wrist band?' He was wigging out because he was tripping. He then tells them I sold him the acid. I got mad then. I sneakily got the acid out of my wallet and threw it on the ground. The guy tries to convince me I'm a drug dealer. I told him man I'm not a drug dealer. The guy I got it from isn't a drug dealer, hes just a middle man getting a few hits of acid everynow and then.
 I'm like 18 or 19 too. It was in the driver side door. Well Danielle had about half a gram of Meth in her wallet which they never found. I thought we were all going to jail. They take Tuck back out of the car and make him sign something.  I did it. He then told us all to leave. We couldn't drive though because we 'were to high.' It was crazy! We should have gotten arrested. He did keep the acid though, which really was weird. And Tuck signed something, hmmmmm.
Well we walked to our cars about 6 miles away. I kept telling tuck he better not have rat on anybody. Well Danielle and I went to the mall parking lot and snorted the rest of the meth. I went back to the park, she jumped my car, I got my acid off the ground, and Then she went to her parents and I went to my parents house. I had about a 45 minute drive.  At one point I looked over and for a split second saw danielle, and she said 'Yeah, thats right. I'm right next to you.'
 I knew I needed sleep bad! I was then pulling into my parents driveway. We have this tree with a bunch of branches on it. I could have swore it was some enormous deer with 10 foot antlers on it. I wigged out. I then went inside, didn't say a word to my parents, and went to sleep. It was crazy, but I wouldn't take any of it back for anything. :)

If I Never Forever Endeavor
by
Holly Meade
This book was about a bird who didn't yet know how to fly.
The bird has to decide if it will try to fly, but it was not sure if it wants to. The bird thought, "If I never forever endeavor" then I won't ever learn. On one wing, he worries he might fail and on the other wing he thinks of how he may succeed. He worries that if he tries, he may get lost in the world. That makes him want to stay in his nest where he's safe.
I think this book would help other children to learn that trying new things can be scary, but sometimes when we try, we can find things that make us happy too. And this book will help others know that mistakes are okay and part of learning.
My favorite part is that the bird tried and learned that she could fly. I also liked that I read this book because it gave me a chance to talk to mom about making mistakes and how I don't like making them. Then I learned they are good and part of learning.
Boys and girls who are 3 to 8 years old would like this book because it teaches about trying a new thing and how it's important to get past being scared so you can learn new things.
I give the book 5 stars since I think it's important for other children to learn about courage.

NDC suggested referendum way back in 2010 – OB Amoah
A Deputy Minister of Local Government and Rural Development, Osei Bonsu Amoah, says it was the then Majority in Parliament which wanted a referendum before an amendment to the constitution for the election of MMDCEs.
He said deliberations on the election of metropolitan, municipal and district chief executives (MMDCEs) have begun for quite some time now with the two major political parties in absolute agreement.
He told Abena Tabi on TV3’s The Key Points on Saturday, November 23 that the two parties agreed that the amendment should be effected.
He said when deliberations on Article 24.3.1 to take away the powers of the president came up in Parliament in July, 2010, the National Democratic Congress (NDC) members wanted a referendum first.
“Our friends on the Majority said we should go for a referendum,” he disclosed, mentioning the likes of Haruna Iddrisu, Alhaji Muntaka Mohammed and Mahama Ayariga as proponents of the referendum.
He said it therefore comes as strange for the party to take a U-turn.


Json.NET supports serialization callback methods. A callback can be used to manipulate an object before and after its serialization and deserialization by the JsonSerializer.
- OnSerializing
- OnSerialized
- OnDeserializing
- OnDeserialized
To tell the serializer which methods should be called during the object's serialization lifecycle, decorate a method with the appropraite attribute (OnSerializingAttribute, OnSerializedAttribute, OnDeserializingAttribute, OnDeserializedAttribute).
Example object with serialization callback methods:
public class SerializationEventTestObject
{
// This member is serialized and deserialized with no change.
public int Member1 { get; set; }
// The value of this field is set and reset during and
// after serialization.
public string Member2 { get; set; }
// This field is not serialized. The OnDeserializedAttribute
// is used to set the member value after serialization.
[JsonIgnore]
public string Member3 { get; set; }
// This field is set to null, but populated after deserialization.
public string Member4 { get; set; }
public SerializationEventTestObject()
{
Member1 = 11;
Member2 = "Hello World!";
Member3 = "This is a nonserialized value";
Member4 = null;
}
[OnSerializing]
internal void OnSerializingMethod(StreamingContext context)
{
Member2 = "This value went into the data file during serialization.";
}
[OnSerialized]
internal void OnSerializedMethod(StreamingContext context)
{
Member2 = "This value was reset after serialization.";
}
[OnDeserializing]
internal void OnDeserializingMethod(StreamingContext context)
{
Member3 = "This value was set during deserialization";
}
[OnDeserialized]
internal void OnDeserializedMethod(StreamingContext context)
{
Member4 = "This value was set after deserialization.";
}
}
The example object being serialized and deserialized by Json.NET:
SerializationEventTestObject obj = new SerializationEventTestObject();
Console.WriteLine(obj.Member1);
// 11
Console.WriteLine(obj.Member2);
// Hello World!
Console.WriteLine(obj.Member3);
// This is a nonserialized value
Console.WriteLine(obj.Member4);
// null
string json = JsonConvert.SerializeObject(obj, Formatting.Indented);
// {
// "Member1": 11,
// "Member2": "This value went into the data file during serialization.",
// "Member4": null
// }
Console.WriteLine(obj.Member1);
// 11
Console.WriteLine(obj.Member2);
// This value was reset after serialization.
Console.WriteLine(obj.Member3);
// This is a nonserialized value
Console.WriteLine(obj.Member4);
// null
obj = JsonConvert.DeserializeObject<SerializationEventTestObject>(json);
Console.WriteLine(obj.Member1);
// 11
Console.WriteLine(obj.Member2);
// This value went into the data file during serialization.
Console.WriteLine(obj.Member3);
// This value was set during deserialization
Console.WriteLine(obj.Member4);
// This value was set after deserialization.

Running multiple Skyline instances
It is possible to run Skyline in a somewhat distributed manner in terms of running multiple Skyline instances and those Skyline instances sharing a MySQL database but analysing different metrics and querying the Redis remotely where required, e.g. Luminosity.
Some organisations have multiple Graphite instances for sharding, geographic or latency reasons. In such a case it is possible that each Graphite instance would pickle to a Skyline instance and for there to be multiple Skyline instances. Or you might want to run mulitple Skyline instances due to the number of metrics being handled. However…
Running Skyline in a distributed, HA manner is mostly related to running the components of Skyline in this fashion, for example using Galera cluster to provide MariaDB replication. Each of the components have their own high availability and clustering methods in most cases and the addition of haproxy, mysqlproxy, load balanced or round robin DNS can achieve a lot of redundancy. Defining how Skyline can be run in HA or clustered is beyond the scope of Skyline itself, it is more an exercise of operations and distributed systems which is beyond the scope of this documentation.
However one word of caution, do not cluster Redis. Although some sharded configuration may work, it is simpler just to use local Redis data. Due to the metric time series constantly changing in Redis clustering or slaving results in mostly the entire Redis data store being shipped constantly, not desired.
That said the actual Skyline modules have certain settings and configurations that are HA or distributed _aware_ to allow Skyline itself to provide the ability to use HA/clustered/distributed components. This section deals with these.
The following settings pertain to running multiple Skyline instances:
With the introduction of Luminosity a requirement for Skyline to pull the time series data from remote Skyline instances was added to allow for cross correlation of all the metrics in the population. Skyline does this via a api endpoint and preprocesses the time series data for Luminosity on the remote Skyline instance and returns only the fragments (gzipped) of time series required for analysis, by default the previous 12 minutes, to minimise bandwidth and ensure performance is maintained.
Running Skyline in any form of clustered configuration requires that each Skyline instance know about the other instances and has access to them via the webapp therefore appropriate firewall, network rules and reverse proxy configuration (Apache or nginx) needs to allow this.
settings.REMOTE_SKYLINE_INSTANCES
is a required list of alternative URLs,
username, password and hostname for the other instances in the Skyline cluster
so that if a request is made to the Skyline webapp for a resource it does not
have, it can return the other URLs to the client. This is also used in
settings.SYNC_CLUSTER_FILES
so that each instance in the cluster can
sync relevant Ionosphere training data and features profiles data to itself.
It is used by Skyline internally to request resources from other Skyline instances to:
Retrieve time series data and general data for metrics served by the other Skyline instance/s.
To retrieve resources for certain client and API requests to respond with all the data for the cluster, in terms of unique_metrics, alerting_metrics, etc.
To sync Ionosphere data between the cluster instances.
Read about settings.HORIZON_SHARDS
see
HORIZON_SHARDS section on the Horizon page.
Hot standby configuration
Although there are many possible methods and configurations to ensure that single points of failure are mitigated in infrastructure, this can be difficult to achieve with both Graphite and Skyline. This is due to the nature and volume of the data being dealt with, especially if you are interested in ensuring that you have redundant storage for disaster recovery.
With Graphite it is difficult to ensure the whisper data is redundant, due to volume and real time nature of the whisper data files.
With Skyline it is difficult to ensure the real time Redis data is redundant given that you DO NOT want to run a Redis slave as the ENTIRE key store constantly changes. Slaving a Skyline Redis instance is not an option as it will use mountains of network bandwidth and just would not work.
One possible configuration to achieve redundancy of Graphite and Skyline data is to run a Graphite and a Skyline instance as hot standbys in a different data center. Where the primary Graphite is pickling to a primary Skyline instance and a standby Graphite instance. With the standby Graphite instance pickling data to the standby Skyline instance.

skyline-2
In terms of the Skyline configuration of the hot standby you configure skyline-2
the same as skyline-1 in terms of alerts, etc, but you set
settings.ANALYZER_ENABLED
and settings.LUMINOSITY_ENABLED
to
False.
In the event of a failure of graphite-1 you reconfigure your things to send
their metrics to graphite-2 and set skyline-2 settings.ANALYZER_ENABLED
and settings.LUMINOSITY_ENABLED
to True.
In the event of a failure of skyline-1 you set skyline-2
settings.ANALYZER_ENABLED
and settings.LUMINOSITY_ENABLED
to
True.
The setting up of a hot standby Graphite instance requires pickling AND periodic flock rsyncing of all the whisper files from graphite-1 to graphite-2 to ensure that any data that graphite-2 may have been lost in any fullQueueDrops experienced with the pickle from graphite-1 to graphite-2 due to network partitioning, etc, are updated. flock rsyncing all the whisper files daily mostly handles this and ensures that you have no gaps in the whisper data on your backup Graphite instance.
With the addition of labelled_metrics, one can use a VictoriaMetrics cluster to achieve HA of the TSDB data for labelled_metrics.
Webapp UI
In terms of the functionality in webapp, the webapp is multiple instance aware. Where any “not in Redis” UI errors are found, webapp responds to the request with a 302 redirect to the remote Skyline instance that is assigned the metric.
Cluster sync
Cluster nodes will sync training data and features profiles data between themselves, however currently saved training is not synced between cluster nodes any user saved training data will only be available on the cluster node on which it was saved. Therefore each cluster node has its own saved training data pages. This only relates to training data that is specifically saved by the user and not normal operational training data that is generated for Ionosphere.

Graham Norton announced as the new host of the 2020 BAFTA Film Awards
Amazing news!
by Kendra BeckerGraham Norton has been announced as the new host of the 2020 BAFTA Film Awards.
The popular chat show host will host the prestigious awards ceremony on February 2, taking over from Joanna Lumley, who has hosted for the past two years.
Graham said: “I’m delighted to be taking the helm of the biggest night in British film. The audience at the Royal Albert Hall will be the biggest sofa I’ve ever faced,”
“I’m honoured to be following in the fabulous footsteps of Stephen Fry and Joanna Lumley.”
BAFTA CEO Amanda Berry added: “With Graham as our host I have no doubt we will deliver a very special celebration of the very best in film, and pay tribute to the most talented and creative people both in front of and behind the camera.”
The BAFTAs is taking place earlier than usual next year, due to the Oscars schedule change.
