They help streamlining the control flow, and take away control code while providing you with an incredibly cool developer experience.

The idea of the script is this: most of the important logic runs in a subshell which is piped through tee and to a logfile, so I don't have to tee every single line of the main logic to get it all logged.

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.

When Sapper renders a page on the server, it will attempt to serialize the resolved value (using devalue) and include it on the page, so that the client doesn't also need to call preload upon initialization.

This scenario demonstrates one drawback of CSS: With all the style rules that need to be applied to multiple elements on multiple pages, things can get pretty redundant. And redundancy can eat up your time and cause friction whenever you need to change a color, font, or any other style aspect across your site.

Custom properties allow a value to be stored in one place, then referenced in multiple other places.

Trapping focus correctly for a modal dialog requires a complex set of events and interaction patterns that we feel is best not duplicated within the logic of this component.

Instead of calling prepare twice to get value from data.

Once again, this isn’t good or bad, it’s just the most efficient way to create something that is similar to something else

Note how we have to duplicate the code between these two lifecycle methods in class. This is because in many cases we want to perform the same side effect regardless of whether the component just mounted, or if it has been updated. Conceptually, we want it to happen after every render — but React class components don’t have a method like this. We could extract a separate method but we would still have to call it in two places.

many CDNs nowadays ultimately source from npm (before caching the JavaScript on their own edge servers). So you'll be guaranteed to have the same library version on the CDN as on npm

Part of the functionality that is returned are event handlers. I'd like to avoid needing to manually copy the events over one by one so the hook implementation details are hidden.

The alternative is to duplicate markup inline:

Do not include the same information in multiple places. Link to a SSOT instead.

Having a knowledge base in any form that is separate from the documentation would be against the docs-first methodology because the content would overlap with the documentation.

New information that would be useful toward the future usage or troubleshooting of GitLab should not be written directly in a forum or other messaging system, but added to a docs MR and then referenced, as described above.

When you encounter new information not available in GitLab’s documentation (for example, when working on a support case or testing a feature), your first step should be to create a merge request (MR) to add this information to the docs. You can then share the MR in order to communicate this information.

If the answer to a question exists in documentation, share the link to the docs instead of rephrasing the information.

There is a temptation to summarize the information on another page. This will cause the information to live in two places. Instead, link to the SSOT and explain why it is important to consume the information

At GitLab, we have so many product changes in our monthly releases that we can’t afford to continuously update multiple types of information. If we have multiple types, the information will become outdated.

RDFa is intended to solve the problem of marking up machine-readable data in HTML documents. RDFa provides a set of HTML attributes to augment visual data with machine-readable hints. Using RDFa, authors may turn their existing human-visible text and links into machine-readable data without repeating content.

There are no plans to deprecate the REST API. To reduce the technical burden of supporting two APIs in parallel, they should share implementations as much as possible.

One thing is certain when it comes to navigation trends, users and designers seem to be fed up with completely hidden styles and demand options that work in similar formats on desktops and mobile devices. This might be one of the reasons a vertical pattern is trending.

Running the same code in the browser and on the server in order to avoid code duplication is a very different problem. It is simply a matter of good development practices to avoid code duplication. This however is not limited to isomorphic applications. A utility library such as Lodash is “universal”, but has nothing to do with isomorphism. Sharing code between environments does not give you an isomorphic application. What we’re referring to with Universal JavaScript is simply the fact that it is JavaScript code which is environment agnostic. It can run anywhere. In fact most JavaScript code will run fine on any JavaScript platform.

Why is the changelog on a separate page and not here? The WordPress.org repository is just another place to download this plugin. I don’t want to maintain too many pages with the same content.
