  • TrailBase: Fast & Open FireBase alternative
    3 projects | dev.to | 28 Nov 2024
    The benchmark sets up a custom HTTP endpoint /fibonacci?n= using the same slow recursive Fibonacci implementation for both, PocketBase and TrailBase. This is meant as a proxy for a computationally heavy workload to primarily benchmark the performance of the underlying JavaScript engines: goja for PocketBase and V8 for TrailBase. In other words, the impact of any overhead within PocketBase or TrailBase is diminished by the time it takes to compute fibonacci(N) for sufficiently large N.

  • When to Use Bun Instead of Node.js
    5 projects | dev.to | 15 May 2024
    In most cases, Bun is faster than Node.js. Zig offers great control over code execution, which allows maintainers to optimize for performance at a low level. Bun is also based on the fast and efficient JavaScriptCore engine. In contrast, Node.js is written in less efficient JavaScript and relies on the slower V8 JavaScript engine.
  • Show HN: Invertornot.com – API to enhance your images in dark-mode
    3 projects | news.ycombinator.com | 25 Mar 2024
    Semi-related - I saw this trick on https://v8.dev a while back, but `filter: hue-rotate(180deg) invert();` can be a neat CSS trick to 'dark mode' some kinds of graphics. The `hue-rotate` help a bit to keep 'blues blue' etc.

    It's far from perfect, but it's a neat trick to be aware of.

  • Top 8 Recent V8 Updates
    5 projects | dev.to | 13 Mar 2024
    V8 is a high-performance JavaScript engine developed by Google. Its purpose is to convert JavaScript code into machine code for execution by the underlying hardware. Primarily developed by the V8 team at Google, the engine focuses on speed and efficiency. In particular, it relies on just-in-time compilation and uses inline caching for high performance.

  • C++ Specification vs Implementation
    3 projects | /r/cpp_questions | 19 Nov 2023
    Exactly the same as JavaScript engines. Be it Mozilla's SpiderMoneky, Google's V8, Apple's Webkit, or Microsoft's Chakra. No matter how specific we draft a specification there is always room for interpretation. Every team has a different take on what part of a spec is describing. Oftentimes it's just a matter of varying pros and cons of different approaches on the road to matching spec; various teams just kind of have to pick a direction and run with it. Other times a spec is not only too vague, but clearly short-sighted to boot.
  • Abstract Syntax Trees and Practical Applications in JavaScript
    13 projects | dev.to | 21 Oct 2023
    Remember that we earlier established that every source gets parsed into an AST at some point before it gets compiled or interpreted. For example, platforms like Nodejs and chromium-based browsers use Gooogle's V8 engine behind the scenes to run JavaScript and of course, some AST parsing is always involved before the interpreter kicks in. I looked V8's source and I discovered it uses its own internal parser to achieve this.

  • TCC and the macOS Platform Sandbox Policy
    1 project | news.ycombinator.com | 9 Dec 2024
    The code snippets are purely declarative because they are reconstructed from the simple bytecode that the macOS sandbox library generates after evaluating the Scheme code. At that point any abstractions present in the source code are long gone and only predicates and actions remain.

    If you look at typical SBPL source code you'll see it tends to contain a mix of straightforward, declarative `(allow …)` policies and custom functions/macros used to simplify repeated patterns. See https://github.com/WebKit/WebKit/blob/11b5279aec6113c661dac3..., for example.

    Even though it makes no sense for (2, 3) to be a result in those cases, that was just how I ended up reading it, and I was exceptionally confused about how the printed output could possibly happen.

    A super nice example of how subtle differences can really change things though.

    As a side note, ASI for JS is actually super easy to implement and the rules are actually really simple (leaving aside whether the feature itself is good :D ) as it's just "these specific statements can have a new line instead of a semicolon" - so in the parser instead of consume(semicolon) you can just do "semicolon or newline" (You can check the logic in JSC in https://github.com/WebKit/WebKit/blob/main/Source/JavaScript... - just look for autoSemicolon() or autoSemi() I can't recall off the top of my head)

  • The Programmer's Brain

    It's not just a problem when you are an amateur. This is sth that every project should provide.

    But there are also many projects which do. Sometimes you need to search a bit for it. Actually I would expect that most big projects have such documentation somewhere in some form.

    - https://github.com/WebKit/WebKit/blob/main/Introduction.md

    - https://www.chromium.org/developers/how-tos/getting-around-t...

    - https://github.com/pytorch/pytorch/blob/main/CONTRIBUTING.md...

    - https://returnn.readthedocs.io/en/latest/getting_started/tec...

    And then for some popular projects you will also find some independent overviews:

    - https://fabiensanglard.net/quake3/ (and many more on https://fabiensanglard.net/)

    - https://tldp.org/LDP/khg/HyperNews/get/tour/tour.html

    - https://realpython.com/cpython-source-code-guide/

    One problem is of course that those documents can be outdated and don't go into much details. But they still will give you important insights and should be a good starting point.

What are some alternatives?
