Bullshit. The ideal refrigerator temperature is already close enough to freezing that any small adjustment you could make is unlikely to do any good. If this was actually a good idea then by your logic (similar to odd love for printer manufacturers) the all wise manufacturers would have already incorporated this into their “smart” fridges.

This is the dumbest shit I’ve ever heard. A standard mono laser printer can somehow print adequately without ANY color toner.

It’s pretty well known in the US that LG washers perform better and have a far better parts and service network than Samsung. You think whatever you want though.

No this is completely incorrect. The filesystem doesn’t break a link just if you open it. Your editor or higher level utility is free to do so (by unlinking and copying the data into a new file/inode), but this is not how the filesystem works.

Trying to shoe horn multiplatform UI into MFC? Just look at Unicode. It’s an unholy mess.

The only toolkit to do what it does? Qt does what it does, even if the approach is not the same (arguably superior), there’s also Tk. There’s also libui and IUP.

> wxWidgets uses the native OS interfaces.

Audacity was fooling no one that it was a native MacOS app, or even a particularly well designed GTK app. The fundamental idea of WX is not sound. Turns out MFC is not a great abstraction for AppKit.

Even Qt uses some higher level native UI interfaces on its respective implementations.

Are you talking about for the AI Pac-Man or the ghosts? Because the ghosts in real Pac-Man don’t have cornering.

NtCreateProcess was not a public Windows API. NT was flexible, that’s not what was being discussed, which should have been clear from the context.

This is not true. NT never had fork, was always based on the assumption of an MMU and Dave Cutler was a well known fork hater in the 80s long before this paper came out and made it cool to be so. By the time Windows 95 was out, the baseline was 386 with an MMU. CreateThread was initially designed for NT in 1993 though (which didn’t support pre-386 CPUs).

For the intended audience of such a paper this is base knowledge.

New comment by epcoa in "I was recently diagnosed with anti-NMDA receptor encephalitis"

Absolutely not to defend what happened but that GAD diagnosis sets in motion the anchoring, because now you have an “established” (and recent) psychiatric diagnosis and it’s all too common that an ED is going to heavily prioritize this as a progression. EDs are just very bad in general about reconsidering a differential for a (new) chronic condition unless it’s flashing like a neon sign, especially when there is an easy enough dispo to reach for, transfer to psych in this case. But even worse, you already had an extensive outpatient workup to hang their hat on. From the history provided the history of a fall is the only thing mentioned that sounded like a slam dunk brewing neurological deficit, and it is not very specific, half the ED are people that fell. I’m sure you’ve read the MDM portion of the ED note, it may or may not give some idea of why neurological conditions were dismissed. Very unfortunate.

There was no snark. If you have something of importance running and the inevitable discovery of an LPE is something you don’t have defense for or can quickly mitigate you’re doing a bad job as a sysadmin. For all general purpose OS in common use today that usually means patch and reboot should be an NBD workaround.

You literally said: “They sell something in their videos and do things in videos that are different from their true self. ”

“Inauthentic” was I still think a close enough reference paraphrase of your statement. Not a value judgement. You even used the word "authentic" in your thesis. And in general I wouldn’t necessarily disagree but I don’t see how it is necessarily related to their choice of personal devices. An internet celeb probably doesn’t use GrapheneOS because the limitations sucks for most people, not because of some calculated subscriber count play.

If you use an unrooted Pixel, why are we even having this conversation, and if not.. well maybe the dude just wants to use a secure wallet.

Regardless of this influencer's "real life" persona I see nothing incongruent about even their "influencer" persona using an iPhone. Therefore I see no relevance to anything in your original comment.

So, this wasn’t a dick sizing contest about who contributes to open source. The point is there is a certain extent I will go to maintain my ideals of using certain systems and it is more than average even for here (the peanut gallery), and on par with the influencer in question, ie I can relate regardless of their “inauthentic” persona. Most people, even those that consider themselves “enthusiasts”, simply won’t go to the effort of reverse engineering or writing drivers - if it were the case there would be a much larger ecosystem of high quality drivers and a larger pool of contributors. I am in that minority and still use an iPhone, and I don’t have a subscriber count.

2. A google pixel isn’t meaningfully more open than an iPhone (I depend on functionality that would be unavailable if rooted). This wasn’t meant to be an iPhone vs android debate. For the purposes of this discussion they are equivalent.

I use Linux as a daily driver, write and modify kernel (mainline and out of tree) and userspace drivers, have reverse engineered various things. ie beyond most of the HN peanut gallery. That said I use an iPhone because I have a day job and nothing “open” is worth dealing with.

Anyone relying on a 30+ year old monolith kernel written in C to not have some exploitable LPEs lurking should stay in basket weaving and out of sysadmin.

New comment by epcoa in "Credit cards are vulnerable to brute force attacks"

epcoa — Fri, 01 May 2026 21:27:13 +0000

So maybe I’m wrong but the belief is that debit card protections are worse than a credit card in the US. I really don’t have the personal time to test this, but I do know that when I dispute on a credit card it is initially removed until proven valid.

Again maybe I’m wrong but I don’t agree they are equivalent. It sure fucking feels that way, the money isn’t threatened from my account.

In addition to nominal fraud prevention (and how is any debit card better) there’s nothing better to claw back transaction fees, so what the fuck am I supposed to do?
