dataangel··on Ask HN: If you were rewriting Emacs from scratch, what would you do differently?
Static typing, lexical scope, good performance on huge files out of the box, extension sandboxing
dataangel··on Automated integer hash function discovery
Wouldn't these be slow because all the operations are dependent? e.g. on x86 I'd use one of the 2 hash functions that has built-in instruction support
dataangel··on Israel shuts down local Al Jazeera offices
I don't agree with Israel censoring websites, but important to keep in mind Al Jazeera is run by Qatar which is a monarchy without real freedom of the press, it's not CNN. They have strong regional interests and an obvious desire to shape the narrative of the conflict. They're not humanitarians.
dataangel··on Lix is a modern, delicious implementation of the Nix package manager
There isn't a single user focused reason in "Why Lix?" The alleged benefits of forking exclusively focus on making developers lives easier.
dataangel··on Prostate cancer includes two different evotypes
Isn't it the case that there are a near infinite number of forms of cancer for any organ? Any combination of mutations that causes unrestricted growth right? So how can it just be 2 forms?
dataangel··on Show HN: Flox 1.0 – Open-source dev env as code with Nix
I tried NixOS because I needed to recreate an environment with a specific GCC version. It was absolute hell, you are likely looking back on your experience with rose colored glasses now that you know how things work. Even really really really basic shit was insane, here's an example: the whole system is built on hashes, and there is no consistent format for them! I was getting an error with hash A even though I explicitly requested hash B, and I couldn't figure out why. Turns out nix can't decide whether to use base32 or base64....

I also tried passing arguments to specify the GCC version in like 10 different ways, *that all failed silently*. Staying far far far away from Nix even though on paper I should love it.

Edit: oh yeah and `nix shell` and `nix-shell` both exist and don't do the same thing

dataangel··on Show HN: Hatchet – Open-source distributed task queue
> Distributed

> Built on PostGRES

Not what people usually mean by distributed, caveat emptor

dataangel··on Hyperbridge: Fast multi-producer, multi-consumer unbounded channel in Rust
Would be great if it had benchmarks
dataangel··on Gemini can't show me the fastest way to copy memory in C# because it's unethical
GPT lets you actually share conversation links. Never trust screenshots.
dataangel··on The Sinusoidal Tetris
Do you always advance to the next stage? If so I appear to win by just clicking "drop" every time.
dataangel··on Bluesky and the AT Protocol: Usable decentralized social media
is there anything particularly compelling about it compared to a centralized platform? honestly still just waiting for the android app to not have terrible startup time and for there to be anybody on it
dataangel··on The King of Curcumin: a case study in consequences of large-scale research fraud
It's a peer reviewed review listing a bunch of studies that according to the OP shouldn't exist so I think it's pretty relevant here.
dataangel··on Apple Vision Pro and ADHD
Why every time a new technology comes out with crappy obvious limitations does somebody feel compelled to write a blog post trying to justify it as actually good? This is just somebody trying to talk themselves into keeping their $3,500 toy
dataangel··on A brief history of the U.S. trying to add backdoors into encrypted data (2016)
IIRC the question is when the phone is totally locked, e.g. if you turn it off then turn it back on and haven't entered the PIN yet. In this state even apple can't get an update to run, the secure hardware won't do it unless you wipe the phone first. And your data is encrypted until you unlock the phone.

In practice though most people are screwed b/c it's all already in icloud.

dataangel··on Researchers uncover potential non-opioid treatment for chronic pain in mice
There are two types of people with chronic pain though:

1) People with a known condition like specific cancers where chronic pain can be a well understood aspect of the condition. Taking the meds doesn't hide anything you and the doctor aren't already aware of.

2) People lumped into a bucket diagnosis (IBS, Fibromyalgia, etc) because the docs don't actually know what's wrong. Taking pain meds is the equivalent of dismissing alerts without investigating. Prior to the opioid crisis even well meaning docs were eager to prescribe because it made patients feel better without addressing any underlying cause.

dataangel··on Zed, a collaborative code editor, is now open source
what are the right flags and gc tunings?
dataangel··on [dead]
this is just an ad
dataangel··on Boehm-Demers-Weiser conservative C/C++ Garbage Collector
I have been writing low latency code for a decade and never seen cascading deletes be a problem. GC on the other hand is a constant latency problem for people.
dataangel··on Fujitsu bugs that sent innocent people to prison were known "from the start"
I think the more important variable is how many subpostmasters there are. If there are millions then 700 is impressive.
dataangel··on Americans are spending billions on stuff they forget to cancel
> which companies have onerous cancellation policies?

dataangel··on Ceph: A Journey to 1 TiB/s
I really wish there was a benchmark comparing all of these + MinIO and S3. I'm in the market for a key value store, using S3 for now but eyeing moving to my own hardware in the future and having to do all the work to compare these is one of the major things making me procrastinate.
dataangel··on Surf the web like it's 1999
The word "blog" seems like a giveaway this isn't from a real archive. I don't remembering hearing it until years later.
dataangel··on FSRS: A modern, efficient spaced repetition algorithm
Huh, hiding part of a word is brilliant. I never thought to do that even though I made tons of cloze cards.
dataangel··on Inside the Steam Deck's APU
Apple recently demonstrated ARM is pretty capable of emulating x86
dataangel··on Fast RISC-V-based scripting back end for game engines
This was posted before and I still have no idea what the rationale is. No desktop PC or game console is RISC-V, so if I'm going to all the trouble to use a scripting solution that requires me to compile my scripts to machine language, why would I target RISC-V? Why wouldn't I just compile to x86-64 directly?

Like, what is the vision here, a LuaJIT that targets RISC-V, running inside my x86-64 game, where the emulator translates the RISC-V back into x86-64... for reasons? Just isolation?

dataangel··on Duolingo Cuts 10% of Contractors as It Uses More AI to Create App Content
reCAPTCHA is his baby.
dataangel··on Peer review is an honor-based system (2008)
He says peer review is for the authors, but I think science being peer reviewed is one of the key points used to convince the public to trust scientific results.
dataangel··on Show HN: GodotOS – Fake operating system interface made in the Godot engine
This doesn't remotely solve the same problem Flatpak does, you are comparing apples and oranges.
dataangel··on Microsoft overtakes Apple as most valuable company
Oh yeah I didn't mean to imply the people there never produce anything that gets widely used in their whole careers, I'm specifically asking if it ever happens while they are at MS Research.
dataangel··on Microsoft overtakes Apple as most valuable company
Ignorant question: Does much actually make it out of MS Research? I've seen lots of interesting retrospectives on stuff that either failed or just has never come out of the lab (Singularity/Midori, accessibility demos showing phones reading restaurant menus to the blind, their tablet pre-ipad, etc.) but I don't think I know of anything they made that really grew up off the top of my head.

I didn't want to say this without doing a little bit of homework so I checked their Wikipedia page (https://en.wikipedia.org/wiki/Microsoft_Research) which doesn't list any accomplishments, just claims they have a lot of patents, and their main site has a publication index (https://www.microsoft.com/en-us/research/publications/?) but publication is not a good metric for ever seeing use.
