Most of these is confirmation of easily observable reality, but the 4x difference in rollback rates, jesus christ.

If they use Rust for new code and C++ changes are all in old code, this could be explained just by older code being more risky to change.

And yet, nobody feels that so viscerally that they feel compelled to write these schoolyard-level insults directed at its leadership every time it comes up in a HN thread.

There was a ton of backlash when Glass launched. Search for "glassholes" to find articles on that topic from back then.

I've updated the GenAI Image comparison site (which focuses heavily on strict text-to-image prompt adherence) to reflect the new Google Gemini 2.5 Flash model (aka nano-banana).

https://genai-showdown.specr.net

This model gets 8 of the 12 prompts correct and easily comes within striking distance of the best-in-class models Imagen and gpt-image-1 and is a significant upgrade over the old Gemini Flash 2.0 model. The reigning champ, gpt-image-1, only manages to edge out Flash 2.5 on the maze and 9-pointed star.

What's honestly most astonishing to me is how long gpt-image-1 has remained at the top of the class - closing in on half a year which is basically a lifetime in this field. Though fair warning, gpt-image-1 is borderline useless as an "editor" since it almost always changes the whole image instead of doing localized inpainting-style edits like Kontext, Qwen, or Nano-Banana.

Comparison of gpt-image-1, flash, and imagen.

Why do Hunyuan, OpenAI 4o and Gwen get a pass for the octopus test? They don't cover "each tentacle", just some. And midjourney covers 9 of 8 arms with sock puppets.

> being workshopped with the C++ community

Honestly seems like a dubious idea. The C++ community that remains are even more "just get good" than before. They still think UB all over the place is fine.

I think that might be true of the language committee, but there's presumably a huge crowd of people with existing c++ code bases that would like to have a different path forward than just hoping that the committee changes priorities.

The "Possible routes forward" section in the linked post mentions this suggestion, and why the author doesn't love it.

> As far as applications go, the most prominent WasmGC deployment is Google Sheets. This spreadsheet app used to evaluate per-cell spreadsheet formulae using Java code, compiled to JS; Sheets has now fully switched to WasmGC (web.dev) instead. There are precious few other prominent examples, however.

Amazon switched the Prime Video app to WebAssembly and doubled its performance. They support 8,000 device types: https://www.amazon.science/blog/how-prime-video-updates-its-...

A recent talk on it with transcript: https://www.infoq.com/presentations/prime-video-rust/

Sounds like they compile rust to wasm, so regular wasm instead of WasmGC is probably enough for them.

It is just a spec on something widely implemented already.

Assuming Next gen PNG will still require new decoder. They could just call it PNG2.

JPEG-XL already provides everything most people asked for a lossless codec. If there are any problems it is its encoding and decoding speed and resources.

Current champion of Lossless image codec is HALIC. https://news.ycombinator.com/item?id=38990568

WebP lossless is close to state of the art and widely available. It's also not widely used. The takeaway seems to be that absolute best performance for lossless compression isn't that important, or at least it won't get you widely adopted.

This proposal reeks of "What color is your function?" https://journal.stuffwithstuff.com/2015/02/01/what-color-is-... . The distinction between sync functions and async functions keeps intruding into every feature. As we can see here, there are Symbol.dispose and Symbol.asyncDispose, and DisposableStack and AsyncDisposableStack.

I am so glad that Java decided to go down the path of virtual threads (JEP 444, JDK 21, Sep 2023). They decided to put some complexity into the JVM in order to spare application developers, library writers, and human debuggers from even more complexity.

bla3 · 7 months ago

That's a critique of `async`, not of `using` though, right? This doesn't seem to make functions more colored than they already are as far as I understand.

Have you tried debugging using the new "reasoning" models yet?

I have been extremely impressed with o1, o3, o4-mini and Gemini 2.5 as debugging aids. The combination of long context input and their chain-of-thought means they can frequently help me figure out bugs that span several different layers of code.

I wrote about an early experiment with that here: https://simonwillison.net/2024/Sep/25/o1-preview-llm/

Here's a Gemini 2.5 Pro transcript from this afternoon where I'm trying to figure out a very tricky bug: https://gist.github.com/simonw/4e208ab9edb5e6a814d3d23d7570d...

In my experience they're not great with mathy code for example. I had a function that did subdivision of certain splines and had some of the coefficients wrong. I pasted my function into these reasoning models and asked "does this look right?" and they all had a whole bunch of math formulas in their reasoning and said "this is correct" (which it wasn't).

How does this compare to https://jcgt.org/published/0011/03/04/paper.pdf? It seems superficially pretty similar.
