typeof v === "number"
Using triple equals to check the results of typeof is totally unnecessary, and a sure sign that someone, somewhere has unthinkingly adopted some dubious advice; it's a code smell/red flag.
A standard equality comparison (using ==) does exactly the right thing while also avoiding association with questions/doubts about the quality of the surrounding code.
Instead read this gems brief source code completely before use OR copy the code straight into your codebase.

I sometimes wondered why the VS Code team put so much effort into the built-in terminal inside the editor. I tried it once on Linux and never touched it again, because the terminal window I had right next to my editor was just massively better in every way. Having used Windows terminals for a while, I now fully understand why it’s there.

Lesson: avoid use of this; work around by defining that
No. Actual lesson: don't do crazy shit; if you're trying to code defensively against this, then your code is too hard to understand, anyway, and you've got bigger problems. (See also: overuse of triple equals and treating it like an amulet to ward off unwanted spirits.)

An #assembler_language is a low-level programming_language designed for a specific processor type. We can produce Assembler by compiling #source_code from a high-level programming language (such as C / C ++). But we can also write #programs in this language ourselves. In turn, we can convert Assembler_code into machine_code using an assembler.

The consumer component will barely change from our last example. The only difference is the way we'll get a reference to our store (since now the store is exported from the JS module):
Now your whole WS logic can be encapsulated in your JS module. That makes for good separation of concern.

Since the reader was able to shape hand and finger as he or she saw fit, we can sometimes recognise a particular reader within a single manuscript, or even within the books of a library. The charming hands function as a kind of fingerprint of a particular reader, allowing us to assess what he or she found important about a book or a collection of books.
I've heard the word "hand" as in the phrase "an operator's hand" used in telegraphy to indicate how an experienced telegraph operator could identify the person at the other end with whom they were communicating by the pace and timbre of the code. I've particularly heard reference to it by code breakers during wartime. It's much the same sort of information as identifying someone by their voice on the phone or in a distinctive walk as seen at a distance. I've also thought of using this idea in typing as a means of secondary confirmation for identifying someone while they input a password on a keyboard.
I wonder if that reference predates this sort of similar "hand" use for identifying someone, if this may have come first, or if they're independent of each other?
Aside to global and local scope there is also something one could call a “block” scope. This is not an “official” type of scope, but it does exist. Block scope was introduced to JavaScript as a part of the ES6 specification. It was introduced along with two new types of variables let and const.
In javascript prettier-ignore ignores the next block, so what I did was just make the next few lines a block.

body script, body style {
This doesn't work well with scripts (and style elements) injected by the Hypothesis bookmarklet or the Wayback Machine's toolbar. On that note, it's pretty poor hygiene on their part to (a) inject this stuff in the body to begin with, and (b) not include at the very least a class attribute clearly defining the origin/role of the injected content. As I described elsewhere:
set the class on the injected element to an abbreviated address like
<style class="example.org/sidebar/2.4/injected-content/">. And then drop a page there explaining the purpose and requirements (read: assumptions) of your injected element. This is virtually guaranteed not to conflict with any other class use (e.g. CSS rules in applied style sheets), and it makes it easier for other add-ons (or the page author or end user) to avoid conflicts with you.
* Monospace fonts always render at 80% of normal body text for some * reason that I don't understand but is still annoying all the same.

Useful advice for commenting code.
I only allowed smaller closures in the code and refactored the rest into separate top-level functions. This is a deliberate move against the common practice of js programmers. Why? Because I noticed closures make code harder to read.
This compatibility simply means that you can have a .githooks folder at the root of your project, where you can organize your individual hooks into folders.
We’ve broken our project up into three different types of packages: apps which are preact apps intended to be bundled and deployed somewhere, modules which are plain npm packages for node/browsers and do not bundle their dependencies, and workers which are either Worker or ServiceWorker scripts entirely bundled up with no imports or exports. We don’t have to keep these three types of packages separated, but it helps us navigate around.

Rather than write new tooling we decided to take advantage of tooling we had in place for our unit tests. Our unit tests already used FactoryBot, a test data generation library, for building up test datasets for a variety of test scenarios. Plus, we had already built up a nice suite of helpers that we coud re-use. By using tools and libraries already a part of the backend technology’s ecosystem we were able to spend less time building additional tooling. We had less code to maintain because of this and more time to work on solving our customer’s pain points.
It also makes it hard to centralize type coercions and default values.
On the security side I think code injection is still a danger. If someone does smuggle js into your js app they'll be able to read your CSRF cookie and make ajax requests using your logged-in http session, just like your own code does
That means if an attacker can inject some JavaScript code that runs on the web app’s domain, they can steal all the data in localStorage. The same is true for any third-party JavaScript libraries used by the web app. Indeed, any sensitive data stored in localStorage can be compromised by JavaScript. In particular, if an attacker is able to snag an API token, then they can access the API masquerading as an authenticated user.
You can find code to generate test fixtures
I am not sure if this is an improvement. To me it does not seem very pretty. Of course I am biased since I also prefer () in method definitions if they have arguments; although I think it is fine that ruby does not mind omitting the (). For my brain, I like the () for visual separation.
One of the consequences (although arguably not the primary motivation) of DRY is that you tend to end up with chunks of complex code expressed once, with simpler code referencing it throughout the codebase. I can't speak for anyone else, but I consider it a win if I can reduce repetition and tuck it away in some framework or initialisation code. Having a single accessor definition for a commonly used accessor makes me happy - and the new Object class code can be tested to hell and back. The upshot is more beautiful, readable code.

CSS seems like the right place to put visual information. On the other hand, few would argue that image "src" should not be specified as an attribute and the height/width seem as tied to the binary image data as the "src" is.

“Who cares? Let’s just go with the style-guide” — to which my response is that caring about the details is in the heart of much of our doings. Yes, this is not a major issue; def self.method is not even a code smell. Actually, that whole debate is on the verge of being incidental. Yet the learning process and the gained knowledge involved in understanding each choice is alone worth the discussion. Furthermore, I believe that the class << self notation echoes a better, more stable understanding of Ruby and Object Orientation in Ruby. Lastly, remember that style-guides may change or be altered (carefully, though!).
“It is less clear that way” — that is just arbitrary, even uninformed. There is nothing clearer about def self.method. As demonstrated earlier, once you grasp the true meaning of it, def self.method is actually more vague as it mixes scopes
I wish to define methods within the class they belong to. Using class << self demonstrates that approach clearly — we are defining methods within the actual singleton class scope.
When we usedef self.method, though, we are defining a method across scopes: we are present in the regular class scope, but we use Ruby’s ability to define methods upon specific instances from anywhere; self within a class definition is the Class instance we are working on (i.e. the class itself). Therefore, usingdef self.method is a leap to another scope, and this feels wrong to me.
Similarly to fashion, code style reflects our credo as developers, our values and philosophy.
Yet, it certainly is important to make the proper choices when picking up style. Similarly to fashion, code style reflects our credo as developers, our values and philosophy. In order to make an informed decision, it’s mandatory to understand the issue at stake well. We all have defined class methods many times, but do we really know how do they work?

There’s several benefits to splitting code into multiple packages, whether it be a library, micro-services or micro-frontends.
he goes on to talk about third party problems and how you're never guaranteed something is written correctly or that even if it is you don't know if it's the most optimal solution
Essentially we're trying to figure out when it's appropriate for "my" code to become "everyones" code, and if there are steps in between. ("Standard library", for example.)
here is my set of best practices.I review libraries before adding them to my project. This involves skimming the code or reading it in its entirety if short, skimming the list of its dependencies, and making some quality judgements on liveliness, reliability, and maintainability in case I need to fix things myself. Note that length isn't a factor on its own, but may figure into some of these other estimates. I have on occasion pasted short modules directly into my code because I didn't think their recursive dependencies were justified.I then pin the library version and all of its dependencies with npm-shrinkwrap.Periodically, or when I need specific changes, I use npm-check to review updates. Here, I actually do look at all the changes since my pinned version, through a combination of change and commit logs. I make the call on whether the fixes and improvements outweigh the risk of updating; usually the changes are trivial and the answer is yes, so I update, shrinkwrap, skim the diff, done.I prefer not to pull in dependencies at deploy time, since I don't need the headache of github or npm being down when I need to deploy, and production machines may not have external internet access, let alone toolchains for compiling binary modules. Npm-pack followed by npm-install of the tarball is your friend here, and gets you pretty close to 100% reproducible deploys and rollbacks.This list intentionally has lots of judgement calls and few absolute rules. I don't follow all of them for all of my projects, but it is what I would consider a reasonable process for things that matter.
Software that is not currently being used gradually becomes unusable as the remainder of the application changes.
Infrequently used portions of code, such as document filters or interfaces designed to be used by other programs, may contain bugs that go unnoticed. With changes in user requirements and other external factors, this code may be executed later, thereby exposing the bugs and making the software appear less functional.
Microlibraries are easier to understand, develop and test. They make it easier for new people to get involved and contribute. They reduce the distinction between a “core module” and a “plugin”, and increase the pace of development in D3 features.
If you don't mind putting the sourcemap url in the minified JS
While I understand orgs wanting not to expose their unminified source, it's security through obscurity (meaning it's not adding any real security).
The only place I can find it is in the sprockets-rails gem. javascript_include_tag calls this: def find_debug_asset(path) if asset = find_asset(path, pipeline: :debug) raise_unless_precompiled_asset asset.logical_path.sub('.debug', '') asset end end

In production, you will never trigger one specific callback or a particular validation, only. Your application will run all code required to create a Song object, for instance. In Trailblazer, this means running the Song::Create operation, and testing that very operation with all its side-effects.
There’s no need to test controllers, models, service objects, etc. in isolation
Instead of one big code pile, activities will gently enforce a clean, standardized way for organizing code.
Suppose that the validate task was getting quite complex and bloated. When writing “normal” Ruby, you’d break up one method into several. In Trailblazer, that’s when you introduce a new, smaller activity.
traditional tracking devices such as radio frequency identification (RFID) and bar codes remain relevant
To understand this helper, you should understand that every step invocation calls Output() for you behind the scenes. The following DSL use is identical to the one [above]. class Execute < Trailblazer::Activity::Railway step :find_provider, Output(Trailblazer::Activity::Left, :failure) => Track(:failure), Output(Trailblazer::Activity::Right, :success) => Track(:success)
Non-blocking suggestion: This is a little more elegant, if you prefer this syntax:
Another thing I don’t like: our asset behavior is decoupled from the assets. If you’re mucking around in your app/assets folder, then you have to first know that such a config exists, and then hunt it down in a totally different config folder. It would be nice if, while we’re working in asset land, we didn’t have to mentally jump around.
While you could program this little piece of logic and flow yourself using a bunch of Ruby methods along with a considerable amount of ifs and elses, and maybe elsif, if you’re feeling fancy, a Trailblazer activity provides you a simple API for creating such flow without having to write and maintain any control code. It is an abstraction.
An activity is a high-level concept to structure code flow
Whether this is the life-cycle of a <user> entity or just a sign-up function, it has to be defined and coded somewhere.
Trailblazer strikes when it comes to organizing business code.
The DSL has a weaker control over the program’s flow — we can’t have conditions unless we add a special step
In functional programming, a monad is an abstraction that allows structuring programs generically
note that TRB source code modifications are not proprietary
In other words, you can build on this software in your proprietary software but can't change the Trailblazer source unless you're willing to contribute it back.
loophole: I wonder if this will actually just push people to move their code -- which at the core is/would be a direction modification to the source code - out to a separate module. That's so easy to do with Ruby, so this restriction hardly seems like it would have any effect on encouraging contributions.
Trailblazer extends the conventional MVC stack in Rails. Keep in mind that adding layers doesn't necessarily mean adding more code and complexity. The opposite is the case: Controller, view and model become lean endpoints for HTTP, rendering and persistence. Redundant code gets eliminated by putting very little application code into the right layer.
Check yourself some shell-sources.
If interested, you can check the plain old /bin/sh signal handling in the source code here.
time run_with_timeout 3 sleep_and_exit 1 7; echo $?
it propagates (Option -p) the returnlevel ($?) so you may use it for your purpose.
ActiveInteraction plays nicely with Rails. You can use interactions to handle your business logic instead of models or controllers.
Why is all this interaction code better? Two reasons: One, you can reuse the FindAccount interaction in other places, like your API controller or a Resque task. And two, if you want to change how accounts are found, you only have to change one place.
Pretty weak arguments though...
I like the clarity of this approach instead of stuffing it in initialize.
Code of Ethics
I do think it's a common pattern that should be solved, and I am probably going to try and solve it as a Gem as opposed to simply writing code that we use in our code base
First of all, we want names to exhibit truth and beauty: to be the right names, and to make our code clean and beautiful. At least, this is what we want to think about our code, but naming’s importance is far more practical.
‘Programs are meant to be read by humans and only incidentally for computers to execute.’
2.L’article 40 du code de procédure pénaleL’article 40 du code de procédure pénale, déjà évoqué, dispose que «toute autorité constituée, tout officier public ou fonctionnaire qui, dans l’exercice de ses fonctions, acquiert la connaissance d’un crime ou d’un délit est tenu d’en donner avis sans délai au procureur de la République et de transmettre à ce magistrat tous les renseignements, procès-verbaux et actes qui y sont relatifs». Cet article a donc pour effet de délier du secret professionnel les officiers publics ou les fonctionnaires en leur imposant de dénoncer au procureur de la République les crimes ou délits dont ils ont acquis la connaissance dans l’exercice de leurs fonctions. Cetteobligation de dénonciation s’impose à tous les fonctionnaires et concerne toutes les infractions. Un médecin de PMI, un médecin scolaire ou un médecin hospitalier peut donc être concerné par cette obligation. Cependant, le non-respect de cette obligation de dénonciation n’est pas pénalement sanctionné, ce qui en limite considérablement la portée.
This is a store we can’t audit, which contains software nobody can patch. If we can’t fix or modify software, open-source or not, it provides the same limitations as proprietary software.
The code is far simpler and easier to understand/verify
’article 434-3 du code pénal prévoit que « toute personne ayant eu connaissance de privations, de mauvais traitements ou d’atteintes sexuelles infligés à un mineur de 15 ans s’expose à des sanctions pénales s’il n’en informe pas les autorités judiciaires ou administratives »
reviewing code takes energy!
the lighting is suitable
The technology's racism means that dark-skinned students may need a lot of suitable lighting.
Maybe $$slots like $$props? My use case is that I'd like to wrap a slot's content in an element that applies styling that I'd like absent without the slotted content. Something like this: {#if $$slots.description} <div class="description"> <slot name="description"></slot> </div> {/if}
It must be called during the component's initialisation (but doesn't need to live inside the component; it can be called from an external module).
Monaco is what VScode, and CodeSandBox, use for code editing. It's obviously one of the best code editors in the world. It's always been on my want-to-try-list and this is the perfect proejct.
A Svelte component that monitors an element enters or leaves the viewport/parent element. Performant and efficient thanks to using Intersection Observer under the hood. Can be used in multiple projects including lazy loading images, infinite scrolling, playing/pausing the video when in the viewport, tracking user behaviour firing link pre-fetching and animations and many many more.
It's a generic abstraction for the logic and styling of elements that pop out from the flow of the document and float next to a reference element, overlaid on top of the UI.
By abstracting the cleanup process in the cleanUp function, the three callbacks — timeout, success, and error listener — look exactly the same. The only difference is whether they resolve or reject the promise.
Keep your patches colocated with the code that depends on them.
Treating the web as a compile target has a lot of implications, many negative. For example “view source” is a beloved feature of the web that’s an important part of its history and especially useful for learning, but Svelte’s compiled output is much harder to follow than its source. Source maps, which Svelte uses to map its web language outputs back to its source language, have limitations.
