Did you use some resource on how to layer immutability on top of B-trees? This is finicky enough that I don't feel comfortable YOLOing.

It might have been better to publicly document and stabilise the LuaJIT bytecode, which would allow people to then come up with whatever syntax they wanted in their own custom frontends.

Can someone point to a resource/tutorial for learning point splatting (the 90s rendering technique)? Gaussian Splatting has completely over taken the search results, and the original technique is now near impossible to find.

What Stockholm Syndrome is this? Why should you have to do this in the first place?

No modern libc uses (or should use) brk() as the heap. Allocate virtual memory using mmap, VirtualAlloc, etc., and manage your set of heaps.

When western politicians and media lectures the world on human rights, I can't help but wonder how funny it is that because westerners front loaded their genocidal violence, they now get to feel superior to others that didn't completely wipe out the conquered.

Yeah, but then I'll have to deal with Embarcadero.

Does this support declaring variables anywhere (as opposed to only in the beginning of a function)? That was my primary complaint when using Lazarus.

New comment by HexDecOctBin in "The USB Situation"

HexDecOctBin — Sun, 03 May 2026 03:52:30 +0000

How do people find Lightning cables robust? Every single one I got from Apple failed around the one year mark. So much so that I finally started buying cheap knockoffs that only lasted 6 months but cost a tenth of official ones. To compare, I haven't seen a single Micro-USB or USB-C cable fail on me whether expensive or cheap. Am I simply uniquely unlucky in the matters of Lightning cables?

> "Abrahamic bad", "Eastern good"

Is that what you read in my comment? Because that is not what I wrote. People sympathise with those who are similar to them. Europeans sympathise with Ukrainians, Muslims with Palestinians, Abrahamics with other Abrahamics. How you got from that to your "Abrahamic bad", I can't even fathom.

Abrahamic societies will naturally be sympathetic to the acts of other Abrahamic peoples and antagonistic to pagan and polytheistic cultures, especially if the non-Abrahamic culture rejects the Abrahamic proselytising that purports to "civilise the heathens" as many Indic societies did. To expect anything else under some expectation of fairness or empathy is nothing but childish naïveté.

New comment by HexDecOctBin in "MacBook Neo and how the iPad should be"

HexDecOctBin — Sat, 25 Apr 2026 06:30:26 +0000

iPads have M-series chips in them that support hardware virtualisation. But Apple goes out of its way to disable the hypervisor for its iOS/iPadOS builds[1]. All they have to do is stop doing that and allow apps to make use of the virtualisation APIs. UTM hypervisor already exists in App Store, so Apple is clearly not against the principle of it. As soon as that happens, running macOS (or Linux) will become elementary.

I was attacked in this way a couple of months back. I use a different email address for each account (of the pattern product@example.com), and use a separate address for Git commits (like git@example.com). It was this second one that was attacked and I ended up with some 500 emails within 12 hours. Fortunately, since I don't expect anyone to actually email me on the Git address, I just put up a filter to send them all to a separate folder to go over at my leisure.

After 12 hours, the pace of emails came to a halt, and then I started receiving emails to made up addresses of a American political nature on the same domain (I have wildcard alias enabled), suggesting that someone was perhaps trying to vent some frustration. This only lasted for about half an hour before the attacker seems to have given up and stopped.

Strangely, I didn't receive any email during the attack which the attacker might have been trying to hide. Which has left me confused at to the purpose of this attack in the first place.

HexDecOctBin — Sat, 28 Mar 2026 13:15:37 +0000

The classic Doug Lee's memory allocator[1] has explicit heaps by the name of mspaces. OP, were you aware of that; and if yes, what does your solution do better or different than dlmalloc's mspaces?

When I read an article, I am expecting to read the author's own experiences and insights they gained from them. Not the regurgitation of an industrial scale word generator.

Then publish the prompts. Let me enter them in an LLM of my choosing and see what bullshit it hallucinates and diff it against the 'article'.

> hopefully steered it right when it made up falsehoods.

"Hopefully"? Publishing something a stochastic parrot dreamed up under your name is ghost writing at best and spreading misinformation at worst.
