rollulus··on Rendering the Sky, Sunsets, and Planets
Incredible what mobile phones and browsers can do nowadays. I remember implementing this paper from 1993 (the absolutely OG for this topic and very readable): “Display of The Earth Taking into Account Atmospheric Scattering” by Nishita et al: https://www.researchgate.net/publication/2933032_Display_of_...
rollulus··on Bun is being ported from Zig to Rust
Rewriting it using an LLM is one. But did all the contributors became as proficient in Rust as they were in Zig over night as well?
rollulus··on How an oil refinery works
That’s because of the primary energy fallacy: https://medium.com/@jan.rosenow/have-we-been-duped-by-the-pr...

TL;DR: the efficiency of converting fossil energy resources into something useful is poor.

rollulus··on How a subsea cable is repaired (2021)
Do they maintain the original connection between the fibers or is that not worth the effort and is a swap not a problem?
rollulus··on Quantum Computers Are Not a Threat to 128-Bit Symmetric Keys
Wouldn’t using opaque tokens have avoided the problem altogether?
rollulus··on LinkedIn uses 2.4 GB RAM across two tabs
They do other unholy things. I don’t know what, but consistently while playing music on my HomePod opening that site makes it stutter within a few minutes, fully stop working shortly afterwards and it needs a reboot to work again.
rollulus··on Conservative Treatment for Endobronchial Blast Injury with Tracheal Rupture
TL;DR: medical case report of a guy who inhaled hydrogen gas, lit a cigarette, blew up internally and survived.
rollulus··on Cloudflare flags archive.today as "C&C/Botnet"; no longer resolves via 1.1.1.2
I think there are two angles to look at this. Yes, there’s the attack on the weblog. But there’s also pressure on archive.today, e.g. an FBI investigation [1] and some entity using fictitious CSAM allegations [2].

rollulus··on Show HN: The Lottery of Life
You repeat the same mistake here:

> I'm simply talking about the simple improbability of, out of all possible lives I could have had, mine being one this relatively comfortable and novel.

That implies that there is a separate organism and an “I” (I used the word soul for that) and that the two were assigned to each other. No, the two are the same. And the probability of you being you is 100%.

rollulus··on Show HN: The Lottery of Life
Your thinking is flawed. It seems to assume that you were pulled from a pool of souls and got assigned to an organism somewhere in time. That’s not the case. What makes you “you” is nothing but your brain cells.
rollulus··on Building a TB-303 from Scratch
I think “simulate” would’ve been a more accurate word than “build”.
rollulus··on UUID package coming to Go standard library
Nice, thanks and I agree.
rollulus··on UUID package coming to Go standard library
Well that depends on your luck, it could be a valid one about 1/16th of the time.
rollulus··on An Interesting Find: STM32 RDP1 Decryptor
Anyone knows why this is called “decryption”? I thought that the mechanism was simply a fuse that would deny reading/debugging operations, is there actual crypto involved?
rollulus··on A Botnet Accidentally Destroyed I2P
This article (with high slop vibes) and another article on their site (linked in the comments) seem to suggest that post quantum encryption mitigated the Sybil attack, without explanation. I fail to understand how the two are even related.
rollulus··on A Botnet Accidentally Destroyed I2P
Cool theory but that should result in other attacks that peak in February too, can you give examples?
rollulus··on I tried building my startup entirely on European infrastructure
[citation needed]
rollulus··on Dark web agent spotted bedroom wall clue to rescue girl from abuse
So do I read it correctly that good old detective work did the job, and that breaking e2e encryption and client side scanning wasn’t needed? Politicians tell me a different story.
rollulus··on Show HN: Minikv – Distributed key-value and object store in Rust (Raft, S3 API)
I thought that your “background in literature” contributed to the “well-written docs”, but that was LLMs!
rollulus··on Vitamin D and Omega-3 have a larger effect on depression than antidepressants
Anecdotal, and even meta-anecdotal, but hey: four months ago I started to supplement omega 3 thanks to this hyperbolic HN comment: https://news.ycombinator.com/item?id=45169875

Unlike the commenter, I didn’t suddenly turn into a chess grandmaster, but I did notice that my winter blues didn’t show up this year, the first time in a decade!

rollulus··on Cloudflare was down
Not weird, that’s tradition by now.
rollulus··on Search tool that only returns content created before ChatGPT's public release
Oh wow, great find! That’s really early days.
rollulus··on Search tool that only returns content created before ChatGPT's public release
Multiple people have coined the idea repeatedly, way before you. The oldest comment on HN I could find was in December 2022 by user spawarotti: https://news.ycombinator.com/item?id=33856172
rollulus··on JSON Schema Demystified: Dialects, Vocabularies and Metaschemas
I used to believe that I was working with JSON schema through OpenAPI 3.0, but then I learned a hard lesson that it uses an “extended subset” of it. And what does that mean? It “means that some keywords are supported and some are not, some keywords have slightly different usage than in JSON Schema, and additional keywords are introduced.” [1]. Yes, that’s a bonkers way to say “this is not JSON schema although it looks similar enough to deceive you”. This word game and engineering choice is so bizarre that it’s almost funny.

rollulus··on DSP 101 Part 1: An Introductory Course in DSP System Design
Because they are at least 28 years old.
rollulus··on DSP 101 Part 1: An Introductory Course in DSP System Design
(1997).
rollulus··on A million ways to die from a data race in Go
TL;DR. Author with “years of experience of shipping to prod” mutates globals without a mutex and is surprised enough to write a blog.
rollulus··on Cloudflare Global Network experiencing issues
Classic. I see issues. Vendor’s status page is all green. Go to HN to find the confirmation. Applies to AWS, GH, everyone.

Edit: beautiful, this decentralised design of the internet.

rollulus··on Go's Sweet 16
I love Go. It makes that I get shit done. I picked up Go more than ten years ago, because it was HN’s darling and when I didn’t know about hype cycles. No regrets.

As always there’s someone on the internet a step beyond. Meet the pussy wetter: https://pussywetter.com/
