arcfour··on Andrew Wiles on proving Fermat’s Last Theorem (1995) [video]
I love these little anecdotes on HN, they are like a little dessert post-main-post. Thanks for sharing :-) what an incredible thing to have had the scoop on!
arcfour··on Should you stop cracking your knuckles?
I'm sorry, but going to a quack doctor is not medical care, much like McDonald burgers would not be a healthy meal regardless of whether or not that's all you can afford.

Except at least in the McDonald's case you have to eat food to survive, so you may not have a choice. You don't have to go to a chiropractor to survive, so it's better to not go there at all than it is to go and receive possibly dangerous treatment from a con artist.

Remember, there is no science behind what they do. They don't know if they're going to hurt or paralyze you because they never went to medical school!!

arcfour··on Mea Culpa – Dark Hours
I have had Claude and Codex look at third party repositories on several occasions as reference material for something I wanted to make my own version of, and not once have they ever cloned it unless I told them to. Sometimes I would notice they would just keep reading the repo through a ton of API calls so I'd just stop them and clone it for them and tell them to look there. And not once was the output anywhere near that close to the original, plus they usually added attribution info if the results were even (unscientific estimate) 50-60% similar.
arcfour··on Everything you do is being recorded
Not mine, UBlock has blocked that since day one, thankfully

> They are mostly just practicing physical therapy without a medical license

Oh, well as long as they're only practicing medicine without a license, I suppose that's okay then...

arcfour··on Should you stop cracking your knuckles?
It's not "probably not" doing anything, it's definitely not doing anything, because chiropractic is quack pseudoscience that has been thoroughly debunked and also has a bunch of other bizarre and fantastical elements to it beyond "cracking your back"
arcfour··on Lost my phone at the office. Claude suggested tracking Bluetooth signal strength
Whenever I ask an LLM to do something and it manages to 1-shot something ingenious/perfect, I get this weird feeling of happiness tinged with looming existential dread echoing softly in the background.
arcfour··on I watched 13 legal pages for two weeks, three of them changed
Was it 4.5 or 4.6 that started using "load-bearing" all the time? Boy, the first time I saw that I knew immediately that was the Next Big Tic for Claude.
arcfour··on Civilian plane crash in New Mexico tied to military GPS blocking
That's like saying "what, it was published in the paper of record in your local area!"

NOTAMs have so many issues it's not even funny. There's so many of them and 9/10 of them are irrelevant for one.

arcfour··on Responding to the next frontier of critical cyber capabilities
> most vulnerabilities are going to be closed in popular software by mid 2027

I think that's a bit hopeful. I think that as long as imperfect humans continue to exist and we continue to train AI models with data from these imperfect humans that vulnerabilities will always exist.

arcfour··on Hardware backdoors in some x86 CPUs
They knew what they were doing by not including "VIA C3 CPUs" before the fourth paragraph. Come on. It should have been in the title.
arcfour··on That time when I failed the Microsoft interview
Gah, I can't remember what the specific trivia was now (ironically), just that some disk wasn't mounting and something in the fstab stuck out to me that I then looked up in the manpages and confirmed was wrong. (I wasn't even the AIX guy, I was just the sysadmin of an app that ran on AIX.)
arcfour··on That time when I failed the Microsoft interview
The speed with which I can remember some obscure AIX partitioning-related fact during an incident, for example, is orders of magnitude faster than the speed with which I would figure out which of 12 marbles is slightly heavier than the others.
arcfour··on Carolina Cloud pays SOFR on unused prepaid credits
Yes, I love maximally restricting rights of others for unclear reasons.
arcfour··on CipherX applies painless permanent tattoos with dissolving microneedle patches
You can already pretty easily handcuff a drunk person and then draw all over them with a sharpie, and that doesn't take 15 minutes of leaving a patch alone.
arcfour··on LLM Honeypot
There is something unnerving about using an LLM to generate a site...that is a joke about AI embodiment.
arcfour··on Exercise works for depression. So why isn't it treated like real medicine?
It's a good question. I could see it working for some people (accountability, companionship) but at least for me, one of my parents is a certified PT and while she has helped a bit, the problem is just more deeply rooted than that unfortunately, at least for me.

But, again, everyone's experiences are different.

arcfour··on Exercise works for depression. So why isn't it treated like real medicine?
Exercise is great on the days I can do it, I love going for a walk. But sometimes when I hear that suggestion - I wonder if those people have ever lain in a totally uncomfortable position in bed for 45 minutes because they felt paralyzed, unable to will their muscles to reposition themselves into something more comfortable. From that perspective, even light exercise seems like walking on the moon; merely a thought, not real.
arcfour··on Five US tech giants' hidden debts soar to $1.65T on opaque AI funding
No, the archive.today (and .ph, .is, etc.) operator configured their nameservers to return invalid responses to Cloudflare's 1.1.1.1 resolvers because Cloudflare doesn't forward EDNS client subnet info (for the privacy of their users). The operator claims to need this information for load-balancing but I don't buy that argument.

As far as I was aware, their issue was resolved, but sometimes I still see failures so I don't really know.

Also, "US-mandated DNS filtering" would be a violation of the 1A except in narrow circumstances (which don't exist here) so I'm not sure that that should be your first thought...

arcfour··on Never argue with your boss (2009)
Yeah. My takeaway was sure, on one hand, arguing with your boss isn't going to end well. On the other hand, if arguing with your boss wouldn't end well (meaning you have a well reasoned technical disagreement, not just being insubordinate) then your boss is a bad boss...
arcfour··on [dead]
It sounds like it could be an interesting case but the weird AI slop writing is a bit much to trudge through.

I mean really:

> What improved (reported)

> Speech, recognition, dressing, continence — multiple functional domains, not a single symptom.

> What we cannot conclude

> No control group, no formal neuroimaging, no established causality. Spontaneous fluctuation and context cannot be ruled out.

Oh gee, thanks for the reminder on how the scientific method works, Claude. That's most certainly not something you can count on your audience being familiar with already if you're writing about a...medical case study, of course.

And why are these two points formatted as two cards with excessively long subheadings instead of something normal like a "paragraph?!"

arcfour··on TypeScript 7
Okay, so I'm not crazy for thinking that declaring an empty, typed array as `const` and then writing/pushing to it is confusing/feels wrong.

I didn't go to college for software engineering or anything so when I ran into that for the first time I assumed there must have been some good academic reason that was simply beyond me as to why it was done that way.

It turns out that no, it's just as weird to those that do have the formal background, boy am I feeling vindicated ;)

arcfour··on Microsoft reveals why Windows 11 keeps saying a file is in use after closing app
No, because this would be kernel level code, so anything else running in the kernel (other drivers) could stomp on your memory and you couldn't do anything about it. No OS protections here.
arcfour··on Microsoft reveals why Windows 11 keeps saying a file is in use after closing app
But the offending module is not necessarily the module listed in the BSOD. It could be a victim too, one that got its memory corrupted by someone else.

That's one reason why they removed it, because it was causing end users to blame vendors/MS when they often had nothing to do with whatever the problem was.

arcfour··on AMD Readies Full Open-Source HDMI 2.1 Support for Linux
Because companies choose not to support Linux. Some popular ACs like EasyAntiCheat support Linux, but game developers (e.g. Facepunch/Rust) choose to block it.

Sure, the Linux kernel will let you load any unsigned kernel modules you want...but cheating is still possible (and happens) on Windows, so...

(Granted, trying to stop someone from running code on their own computer is a losing battle/stupid idea from the get-go)

> Sure, it's to serve they own interest in selling Steam-branded hardware

But that's fine, even preferable? I love it when my interests and someone else's interests naturally align themselves.

arcfour··on F3
But that is 97% of the value proposition.
arcfour··on F3
Yes...my first thought. No way in hell anyone actually trusts this.

(And as if we didn't trust the compiler enough already!)
