In v3, svelte-preprocess was able to type-check Svelte components. However, giving the specifics of the structure of a Svelte component and how the script and markup contents are related, type-checking was sub-optimal. In v4, your TypeScript code will only be transpiled into JavaScript, with no type-checking whatsoever. We're moving the responsibility of type-checking to tools better fit to handle it, such as svelte-check, for CLI and CI usage, and the VS Code extension, for type-checking while developing.

highly recommended that the resulting image be just one concern per container; predominantly this means just one process per container, so there is no need for a full init system

Doing everything PID 1 needs to do and nothing else. Things like reading environment files, changing users, process supervision are out of scope for Tini (there are other, better tools for those)

Focus is better than features.

Write modules that do one thing well. Write a new module rather than complicate an old one.

Webshim is also more than a polyfill, it has become a UI component and widget library. Webshim enables a developer to also enhance HTML5 capable browsers with more highly customizable, extensible and flexible UI components and widgets.

The assert method is used by all the other assertions. It pushes the second parameter to the list of errors if the first parameter evaluates to false or nil.

Systemd flies in the face of the Unix philosophy: 'do one thing and do it well,' representing a complex collection of dozens of tightly coupled binaries

"Headless Tippy" refers to Tippy without any of the default element rendering or CSS. This allows you to create your own element from scratch and use Tippy for its logic only.

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.

Popper has a sole goal: position elements. That's why we call it a "positioning engine" and not a "tooltip library".

Dropped FFmpeg support (focus on primary functions instead)

it focuses on compiling non-standard language extensions: JSX, TypeScript, and Flow. Because of this smaller scope, Sucrase can get away with an architecture that is much more performant but less extensible

React does not attempt to provide a complete "application library". It is designed specifically for building user interfaces[3] and therefore does not include many of the tools some developers might consider necessary to build an application.

Rollup also does something very different compared to the other bundlers. It only tries to achieve one simple goal: Bundle ES modules together and optimise the bundle.

If your reaction to the video was 'fine, but if we use TypeScript and write plugins for each editor then we can get all the autocomplete and syntax highlighting stuff' — in other words, if you believe that in order to achieve parity with CSS it makes sense to build, document, promote and maintain a fleet of ancillary projects — then, well, you and I may never see eye to eye!

Pipes are great for taking output of one command and transforming it using other commands like jq. They’re a key part of the Unix philosophy of “small sharp tools”: since commands can be chained together with pipes, each command only needs to do one thing and then hand it off to another command.

The only goal is correctness. Code style is not a consideration. Providing the level of configuration necessary to make everyone happy would be a huge distraction from the main purpose. After conversion, I recommend using rubocop's awesome --auto-correct feature to apply your preferred code style.

Falcon tries to do as little as possible while remaining highly effective.

One thing well. rbenv is concerned solely with switching Ruby versions. It's simple and predictable.

It doesn't use a database (unlike Keepass) and thus doesn't open all passwords at once. Just one at a time. Since it's just a directory of encrypted files, you can access your passwords with any PGP-compatible tool.

Using find and cpio is a more unix-y approach in that you let find do the file selection with all the power that it has, and let cpio do the archiving. It is worth learning this simple use of cpio, as you find it easy to solve problems you bang your ahead against when trying tar.

As Onivim 2 completely handles the rendering layer, this Vim-modelled-as-a-pure-function could focus on just buffer manipulation.

It is responsible for

do something specific and do it well

Epiphany aims to present the simplest interface possible for a browser. Simple does not necessarily mean less-powerful. The commonly-used browsers of today are too big, buggy, and bloated. Epiphany is a small browser designed for the web: not for mail, newsgroups, file management, instant messaging, or coffeemaking. The UNIX philosophy is to design small tools that do one thing and do it well.
