Meson is a project to create the best possible next-generation build system. It is optimized for extremely fast full and incremental builds without sacrificing correctness. It supports cross compilation for many operating systems as well as bare metal. It has built-in multiplatform dependency provider that works together with distro packages.




Meson - The Build System

Extremely fast node.js logger, inspired by Bunyan. It also includes a shell utility to pretty-print its log files. Due to Node's single-threaded event-loop, it's highly recommended that sending, alert triggering, reformatting and all forms of log processing is conducted in a separate process. In Pino parlance, it is called as log processors "transports", and recommend that the transports be run as separate processes, piping the stdout of the application to the stdin of the transport.

Rayon is a data-parallelism library for Rust. It is extremely lightweight and makes it easy to convert a sequential computation into a parallel one. It also guarantees data-race freedom. Rayon makes it drop-dead simple to convert sequential iterators into parallel ones: usually, you just change your foo.iter() call into foo.par_iter(), and Rayon does the rest.
 
Parallel iterators take care of deciding how to divide your data into tasks; it will dynamically adapt for maximum performance. If you need more flexibility than that, Rayon also offers the join and scope functions, which let you create parallel tasks on your own. For even more control, you can create custom threadpools rather than using Rayon's default, global threadpool.

AVA is a test runner for Node.js with a concise API, detailed error output, embrace of new language features and process isolation that lets you develop with confidence. AVA automatically detects whether your CI environment supports parallel builds. Each build will run a subset of all test files, while still making sure all tests get executed. It automatically removes unrelated lines in stack traces, allowing you to find the source of an error much faster.
 
Its features include:
<ul>
<li>Minimal and fast</li>
<li>Simple test syntax</li>
<li>Runs tests concurrently</li>
<li>Enforces writing atomic tests</li>
<li>No implicit globals</li>
<li>Includes TypeScript definitions</li>
<li>Magic assert</li>
<li>Isolated environment for each test file</li>
<li>Promise support</li>
<li>Async function support</li>
<li>Observable support</li>
<li>Enhanced assertion messages</li>
<li>Automatic parallel test runs in CI</li>
<li>TAP reporter</li>
</ul>

Robolectric is the industry-standard unit testing framework for Android. With Robolectric, your tests run in a simulated Android environment inside a JVM, without the overhead and flakiness of an emulator. Robolectric tests routinely run 10x faster than those on cold-started emulators. Robolectric supports running unit tests for 16 different versions of Android, ranging from Jelly Bean (API level 16) to SV2 (API level 32).
 
Unlike traditional emulator-based Android tests, Robolectric tests run inside a sandbox which allows the Android environment to be precisely configured to the desired conditions for each test, isolates each test from its neighbors, and extends the Android framework with test APIs which provide minute control over the Android framework’s behavior and visibility of state for assertions.
