pixelesque··on US interest rates raised for first time in three years
It was blatantly obvious Iran would do that if attacked. This has been known for decades.

The only thing previously stopping them holding the strait "hostage" was the threat from the US of doing an "Operation Praying Mantis v2" and destroying their navy and attacking them.

And when the US did that anyway, they had nothing to lose.

They've got the IDL files as well for the APIs, but you can't use them without their libs:

DDS sort of took over from CORBA in the military domain, and the statically-typed IDL was still quite similar to CORBA last time I looked at it, so that takes you back to around 1998 when CORBA was being used a lot in the military in my experience.

What other protocols and systems were you thinking of that can provide (depending on broker) hard-realtime delivery that can be used in safety-critical systems?

pixelesque··on Show HN: Pelican-bicycle alternatives
Its giraffe / grandfather clock one is pretty bad... (two necks? wearing a suit?)

Weird as well, it's clearly pulled out some 1884 patent on clock designs, and a quick ddg/google doesn't show it as anything to do with grandfather clocks.

Sounds like it might not have been fully fixed after 2023 then.
pixelesque··on A misalignment of AI in mathematics
Other than the fact it's mathematicians signing it, why is mathematics special in this regard: surely this generally applies to a lot of different industries and sectors of research / academia?

Mathematics is being used as a benchmark because there are some high-profile awards in this area I guess, and possibly because 2/3 years ago LLMs were pretty atrocious at it so the level of improvement has been significant.

pixelesque··on Apple debuts iPhone 18 Pro and iPhone 18 Pro Max
I wish they'd alternate each year or something between iPhone / iPhone mini if they're struggling for sales.

The body shapes and cases seem to change each year anyway now, so it's not like people get to re-use cases that much anyway...

Same, got battery replaced 5 months ago.

Wish I'd got the biggest storage size when I bought it though :(

pixelesque··on DeepSeek launching v4.1 flash cheaper and more capable than v4 pro
Where are you seeing them having an issue with the larger (Pro) model?

The announcement specifically says 4.1 Pro will be released in the future.

I've had this for a few months trying to log into https://console.vultr.com/...

It does it for me if I use a VPN (Mullvad) - if I don't use a VPN then I haven't noticed I get them.

But yeah, very annoying.

pixelesque··on NASA: Fill in a name, and you can have an exclusive coordinate in the universe
It's not even that though if we are going to be nit-picky: it's a coordinate (not quite sure what the pixel extent would subtend to solid-angle-wise, but...) based off the coordinate frame of where the space telescope will be when the image is taken in spherical coordinates.

That's not "exclusive". The "pixel" is the exclusive bit.

pixelesque··on NASA: Fill in a name, and you can have an exclusive coordinate in the universe
Title doesn't match submission: it's not really a "coordinate" in 3D space, you "adopt" a pixel from the early imagery taken by the Nancy Grace Roman Space Telescope.

Maybe that can be reverse-projected back to something like a coordinate (if you know the distance), but it's not the same thing.

pixelesque··on OpenClaw 2.0, Accidentally
Hermes' Github has 12K open issues and 25K pull requests.

I assume they're using agents to sort through all the slop?

pixelesque··on Tencent Releases and Open-Sources Tencent Hy4 Preview
Looks okay to me.

The first column has both the Hy4 and Hy3 scores overlaid on one another (Hy4 is darker blue and the taller one), with both scores written below the top of the respective bar - maybe you're seeing that?

pixelesque··on Ask HN: GitHub employees what's going on? Why?
Yes, but come on...

That's due to the need for ultra-fast memory and inference compute, it's not the same thing.

pixelesque··on Ask HN: GitHub employees what's going on? Why?
Is that the same as storing state in a DB and on a filesystem though?

Like, I get there are other features they have, and things like history, but I don't think it's quite the same.

Isn't most (not all) of the LLM's resources stateless compute to a large degree?

(Not defending MS at all though, I currently can't create a PR on the required branch for my work (won't load the branch list) and their availability is really bad recently).

pixelesque··on On AI regulation and messaging
As someone typing this on an M1 Mac with 32 GB of RAM who tried using 3.8 27B (Q4_K_M) yesterday in both LM Studio and llama.cpp, I wouldn't call it particularly usable in terms of token speed. (and that was with `--spec-type draft-mtp` for llama.cpp).

If you want to leave it running with the fans going crazy for 40 mins or overnight or something, fair enough, but otherwise it doesn't seem worth it to me. It's certainly not "interactive", even taking into account the over-thinking it does by default.

The 3.6 (maybe they'll release a 3.8?) MoE model is much more usable (but obviously not as good) on this machine spec.

Any examples of this?

pixelesque··on DeepSeek-V4-Pro-0813 Publish
I heard on the "China Talk" podcast talking about China and exports of open weight models they often do this because under Chinese law, they have to submit each new public model release to a government department for "validation", and if they keep the version the same, they don't need to re-submit it.
pixelesque··on DeepSeek V4 Pro 0813
I've found Pro to be a lot better per "task" than the recently released Flash for code reviews and things (via OpenRouter running in pi.dev).

Flash makes a lot more initial mistakes, and then has to re-check stuff, and produces much more output compared to Pro. It often gets to the correct result eventually, but the output volume is often 5x more than for Pro, and the initial outputs are often wrong, with the first few saying something wrong (like there's a bug, or the code won't compile when it does), and then saying things like "Wait, let me re-check:", or "Actually, looking at it more carefully:" and then it thinks a bit more and eventually gets to the right answer.

pixelesque··on Is it all just vapourware?
You could convert ~800 lines of scalar float processing templated C++ code that used mixins for wrapping logic and float/double to well-optimised SIMD code for two different ISAs (without using wrapper class helpers, it wrote the full intrinsics) in under 5 minutes and write tests for them at the same time?

It's the time compression I'm impressed with.

pixelesque··on Is it all just vapourware?
It's an example of useful work. 11 years ago, I would have been able to use that code in production for the company I worked at at the time, and the conversion would have been very useful.

I'm also using Github Copilot at work, but I can't as easily talk about what I'm doing there.

pixelesque··on Is it all just vapourware?
The tests and notebooks maybe: not the unrolling and re-architecting to use masking SIMD-ification. I used to do SIMD stuff a lot over the last 17 years, and it would have taken me probably a day to do that (convert 7 algorithms, all with support for various wrapping/mirroring/clamping extent-handling, so around 800 raw source file lines of templated C++) to use SIMD - and well.

Then it probably would have taken me at least half a day to think about what tests to write and to make them.

It did it in around 5 minutes. I had to check it, and it wasn't perfect, but it compiled, ran, and was very close.

pixelesque··on Is it all just vapourware?
I had DeepSeek 4 Pro do a very good job yesterday of loop-unrolling and SIMD-ifying (both SSE/AVX and ARM Neon versions) some very old scalar Col3f image processing and resampling/resizing C++ code I hadn't touched in 12 years or so.

It also wrote some unit tests that validated the kernel sampling weights, and wrote some Jupyter notebooks to go along with the kernel algorithms as comparisons.

It's not just web dev... It helps (a lot in some cases) if you ask very specific things rather than just "make this vague thing", but I'm more and more coming round to the conclusion it is now a useful dev tool (until two months ago I was a sceptic).

pixelesque··on New Zealand lost its music media, and what we're building to replace it
> Live performance revenue reached $329 million, well above pre-Covid levels.

Is that inflation-adjusted? And as the article points out, very little of that is local talent, so it's likely some of that's due to the cost of tickets.

As someone who lived in NZ (although Wellington) for 10 years until last year, the local music scene was there, but at least in Wellington, the change in the 10 years I was there was considerable: The earthquake in 2016 progressively caused several venues on Cuba Street to close due to building regulations, and Covid was a significant shock as well, with some of the smaller (although most places in Wellington were small!) gig rooms / bars / breweries that would often host bands closing.

There was still Valhalla, San Fran, The Rogue & Vagabond and others, but it just didn't feel as much was going on other than for things like Cuba Dupa street festival, etc, or the Jazz weekends that would be held.

As the article points out, this is not localised to NZ, it's happening in Australia and the UK as well in terms of venues/pubs closing and live music not being quite the draw it once was because of that.
