diffuse_l··on GPT 6.1 Sol: Near-Astra intelligence for a fifth of the price
I'm describing what I got from 20x Codex vs Claude 5x. Codex is just not worth the money, at least for me. What's flipped is the value you get for each of those

OpenAI 20x wasn't 20x even before that change. I got a lot more from Claude 5x than Codex 20x...

Seems like weekly allowance got reset back to 0%, pretty usual when they deploy new models.
diffuse_l··on sp.h: Fixing C by giving it a high quality, ultra portable standard library
For short strings (probably most of them) - use a byte for the length (at the string/symbol definition site, alongside the offset) (adds 1 byte * symbols, use high bit if necessary to add bytes for longer strings). You need the offset into the table anyway. It isn't strictly better, but it isn't strictly worse, and it gives you the option to reuse sub-strings.
diffuse_l··on Sp.h is the standard library that C deserves
Nothing prevents you from using a shared pool of strings that don't have null terminator. It can even be more efficient, since you don't have the null byte to handle at string end. Depending on the maximum string length you want to support, it doesn't even have to take more space.
diffuse_l··on MacBook Neo Deep Dive: Benchmarks, Wafer Economics, and the 8GB Gamble
Complete assembly. Wouldn't call it trivial, but not super hard either. I wouldn't dream of doing this without the complete assembly, not worth the hassle. You run the risk of ruining something, but for me the reasoning was that worst case I'd still have a conputer I can attach to an external monitor. Replacement itself is mostly removing screws and cables carefully - followed the ifixit guide.
diffuse_l··on MacBook Neo Deep Dive: Benchmarks, Wafer Economics, and the 8GB Gamble
Had a similar issue - some of the display was garbled for more than a year. Had a replacement screen from aliexpress lying around that cost 126$ two and half years ago, got to do the replacement a few weeks ago, as the kid needed a laptop for school. Turns out the replacement screen resolution was not the same as the original, but it still works fine, took ~1 hour for the replacement.

So for me it did make sense to repair - it costs less than a new laptop, at least

diffuse_l··on XML is a cheap DSL
That's if you parse the into a DOM and work on that. If you use SAX parsing, it makes it much better regarding the memory footprint.

But of course, working with SAX parsing is yet another, very different, bag of snakes.

I still hope that json parsing had the same support for stream processing as XML (I know that there are existing solutions for that, but it's much less common than in the XML world)

diffuse_l··on How many registers does an x86-64 CPU have? (2020)
Some minor nitpicks, but hey, we're counting registers, it's already quite nitpicky :)

Add far as I van remember, you can't access the high/low 8 bits of si, di, sp. ip isn't accessible directly at all.

The ancestry of x86 can actually be traced back to 8 bit cpus - the high/low bits of registers are remenants of an even older arch - but I'm not sure about that from the top of my head.

I think most of the "weird" choices mentioned there boil down to limitations that seem absurd right now, but were real constraints - x87 stack can probably traced back to exposing minimal interface to the host processor - 1 register instead of 8 can save quite a few data line - although a multiplexer can probably solve this - so just a wild guess. MMX probably reused the register file of x87 to save die space.

diffuse_l··on Gaussian Splatting – A$AP Rocky "Helicopter" music video
Too bad, but I managed to watch about 30 seconds of the video before getting motion sickness.

Seems like a really cool technology, though.

I wonder if anyone else got the same response, or it's just me.

diffuse_l··on What an unprocessed photo looks like
Really enjoyed the article, thanks! A small nit - I think you have a small mistake in the value range at the start - 136000 should probably be 13600?

It was pretty clear towards the middle of the piece that an ai was involved writing this piece, which was unfortunate, since it distracted me so much from the subject that I couldn't complete reading it...

diffuse_l··on Why JPEG XL ignoring bit depth is genius (and why AVIF can't pull it off)
Well, at least the first half was somewhat useful...
diffuse_l··on Why JPEG XL ignoring bit depth is genius (and why AVIF can't pull it off)
It mostly rehashes the point of using float instead of integer representation, and uses different headers (radical solution, why this matters, secret weapon, philosophy, the bottom line) for streching what could be said in a few sentences into a few pages.
diffuse_l··on Why JPEG XL ignoring bit depth is genius (and why AVIF can't pull it off)
I think the article could be better and get the point across with half the length and without the second half of it being full of ai generated list of advantages, or using that space to give some more technical information

For some reason, it really bothers me that under one of the images there is a caption that says "the pink cube", but the cube is in a shade of blue...
diffuse_l··on Ask HN: Why hasn't x86 caught up with Apple M series?
It's more than that. They have an unlimited license to arm designs, and can change them as they see fit, since they were an early investors (or something along those lines). Other manufacturers can't get these terms, or if they can, it will be prohibtly expensive

I'm pretty sure that the website will reside in cache in any case.

I'm wondering if the usage of an em-dash in the article (somewhere towards the middle) is self-aware trolling, or just the result of excessive ai use...

diffuse_l··on When Is WebAssembly Going to Get DOM Support?
Flash was a security nightmare, with multiple vulnerabilities discovered regularly.

It was eventually killed because Apple decided it won't support it on the iPhone.

Indeed, more than you ever wanted to know about the A20 line: https://aeb.win.tue.nl/linux/kbd/A20.html (from your article)

This is one hell of a rabbit hole...

diffuse_l··on Repaste Your MacBook
I tried to repair a macbook air, and did manage to tear the microphone cable, because I didn't notice the connector :|

Like you said, you need to be careful, but you better be prepared to pay dearly (or manage without) for your mistakes...

diffuse_l··on The Wright brothers invented the airplane, right? Not if you're in Brazil
It was reaveled how dangerous it was around 1986, after the Challenger disater. There were too many incentives to ignore it. Commercial crew would probably not come to be (at least not in its current form) if SpaceX wasn't around to prove that it's possible
diffuse_l··on How I got 100% off my train travel
This reminds me that I once worked in one city, and attended university in another city.

At some point, there were train lines works that lasted for a few years, which meant that almost any train ride was delayed. You got a ticket back for half an hour delay, and two for a full hour.

In addition, my workplace paid me a set amount of money to cover ttain travel expenses for each work day.

I think that for most of my studies I effectively didn't pay for train travel, and had time to work while on the train.

You did have to wait in line to get the ticket after the train ride, and the train officer wasn't too happy about giving out tickets, bit it usually worked...
