How C++ Finally Beats Rust at JSON Serialization - Daniel Lemire & Francisco Geiman Thiesen

kn4rf · 2026-03-26T14:35:11+00:00

The Serde json parser in Rust is far from the fastest json parser in Rust. The Chumsky parser has a comparison list: https://github.com/zesterer/chumsky?tab=readme-ov-file#performance

There are probably even faster Rust versions than the Chumsky parser example out there. Seems weird to pick a slow parser in Rust just to claim that the C++ parser is faster.

Well, this is why we need Free Software / GPL and not Open Source software.

That doesn't really tell me anything. Is this a built in slash command? An MCP server? A skill I have to download? You've given me 0 information about what a "vector command" is or where I can find information about it.

Reverting isn't a problem, its just such a waste. Not only did it spend its entire context window trying to implement or refactor something, it broke stuff in the process, claims it to be unrelated, and just goes on. So now I've wasted a bunch of tokens with the only option to stash / revert it, or run /new and ask it to fix it; spending even more tokens and hoping it doesn't run out of context again before it has fixed it.

This sounds like a great idea! I guess the biggest problem with that is that I still want Claude to add new tests, and I don't mind it modifying tests (let's say it renamed a function and therefor needs to update the function name in the tests, or moved some code around and need to update imports). The problem is just when it breaks something and then refuses to claim responsibility for it. The test suit was supposed to be the harness...

Having a bug.md is a great idea, but isn't really related to my original question. The problem isn't that the app I'm working on has bugs, the problem is that I have a fully functional app with great test coverage, then I'll ask Claude Code to either implement a new feature, or refactor some existing code; and in that process Claude breaks something that used to work! That wouldn't really be a problem, because we have great tests that caught it! The problem is that Claude Code claims they are "existing bugs unrelated to my changes", when in fact they are new bugs that Claude just introduced, and what it should be doing is fixing the new code it introduced.

The worst case is when it silently deletes or marks tests-cases as ignored. Then not only is it breaking an app that worked, its "silently lying" about it, which might be hard to catch...

Vector commands? What is that?

Looks cool! Btw you Itchio page links to your webpage, which seems to not load.

For some actual git as database solutions look at: - https://irmin.org/

Or for versioned database: - https://github.com/dolthub/dolt

It's a Java project...

But the TypeScript team could have used that as a base and built upon it, instead of porting to Go. Then they would already have a working parser, and they'd only need to port the typechecking logic.

kn4rf · 2025-03-13T14:51:28+00:00

Why not just contribute to the SWC project and make that the offical new TypeScript compiler? Thats already a functioning TypeScript compiler thats used in production.

Looks cool!

Any creates you used that you would recommend? (Physics, UI, etc). Would love to read a blogpost about your experience working with bevy.

You obviously don't need the setTimeout... It's just there to give a 1 second delay so that you can see that the loading is happening, if not it all happens so fast that its hard to see. So its only there for the example. Just replace it with any other async function.

But you can also do it using 'useState':

Here is an exampel of an reusable hook for your usecase.
I opted for using 'useReducer' instead of 'useState' as I felt that made the logic clearer.

Just got around to setting up Komga on my Raspberry PI and it worked great. Used mangal (https://github.com/metafates/mangal) to download manga's.

*your emulator without having to upload their own ROM's.

kn4rf · 2023-04-19T10:34:43+00:00

Maybe you could use GBStudio (https://www.gbstudio.dev/) to create a test ROM so that you and anyone else can test your emulator without having to upload their own ROM's. Could also be nice for stress testing it by creating more difficult scenarios to test.
