That name brought back memories.

Unfortunately I didn’t do anything as impressive as modding a game; I read the book because the writing style itself was engaging and gripping like a novel.

You are asking for a look that’s very niche. Not many people hate anti-aliasing so much. GNOME still has a simple UI to turn off anti-aliasing but not many apps respect that. The modern text rendering pipeline is just way too complicated from font lookup, ligatures, shaping, etc. To achieve this look in web views you’ll most certainly need to do it in

But models are trained on human data, human writings, and human thoughts. So models are acting to imitate humans.

You may have to internally use bignums since collatz orbits can become very large before shrinking.

I start from the OpenWrt devices page. Filter by the Wi-Fi revision I need (ac or ax), opt for 4 cores or more and sufficient RAM, and then read the forum posts and the device page to make a shortlist. Then I look at price and availability.

It’s a standard way to do pre and post conditions. Clojure pre and post conditions also behave this way. If you force these conditions into compile-time checks, well, then you are introducing a second type system with refinement types into the language. And type checking would take a long time. Imagine someone writes a precondition for a function where its integer argument x needs to satisfy collatz(x)==1; do you now expect the compiler to prove the collatz conjecture or verify it for all 64-bit integers every compilation?

My experience using pre and post conditions in Clojure makes me really like them. They are a small but meaningful improvement over plain old assertions. And yes being able to turn them off is a feature not a bug. Don’t expect them to be like LiquidHaskell.

For some reason I read a long time ago that offloading is unreliable and I turn it off everywhere. I’m glad that the author also had to turn it off to fix Qualcomm’s bugs. But in general, is this still good advice in 2026?

> When you open the AirPods box for the first time does the iPhone do that animation and say "Set up AirPods..." etc?

There are many amusing videos of someone in China setting up counterfeit AirPods on a train, and every single unlocked iPhone on the train car did that animation. The counterfeiters took pride that their product had a “stronger connection” than the real thing.

> I do appreciate that passkey adoption has led to wider support for hardware security tokens

In my experience this simply didn’t happen. Many sites support passkeys but only the native passkey stored on the current device, but not a hardware security key. Many sites don’t even allow multiple passkeys, which is frankly required if you use hardware security because you will want multiple pieces of hardware in case one is misplaced.

I fail to see why they also need to mention Mononoke when they already attributed inspiration to Sapling, when Mononoke is a component of Sapling.

I no longer go to my local community hospital for any purpose. It’s either an inconsequential thing that my primary care doctor can deal with, or go to a large reputable hospital even if it’s a one-hour drive away.

GNU is extremely similar to the proprietary Unix flavors that came before it. Is that a problem?

Absolutely not. When I create projects I only credit other existing systems if they are a direct inspiration. If I independently come up with the same idea as someone else I see no reason for me to do the due diligence and credit them.

Please don’t. This is really a matter of personal preferences. I like long informative landing pages that as I scroll, give me more and more reasons to try the software.

Compare the omp landing page a few months ago versus now: https://web.archive.org/web/20260624030333/https://omp.sh/ versus https://web.archive.org/web/20261007154534/https://omp.sh/ The former does a compelling job telling me why I should try it by listing its advantages. By the time I got to hashline I became convinced. The latter landing page has a single sentence that’s generic and vague. I would not have tried omp at all if its landing page looked like what it is today.

That’s something Opus can also do. Perhaps by coincidence I also recently debugged shader bugs where Opus dumped the resulting render to PNGs and then using Python PIL to do comparisons. It purposefully added false colors too.

I think it’s a typical strategy for scammers to create a new account and then immediately try to buy an optional service with a stolen credit card.

What you did isn’t wrong, but is unfortunately very similar to what real scammers do. The heuristics behind these anti-abuse efforts are always going to have false positives.

Isn’t it backwards? If everyone had a little bit of home generated power, then the actual energy part of the bill becomes smaller, and the cost of transmission becomes an even greater fraction of the total cost.

And since transmission cost is typically bundled with the energy cost, it means the final retail energy price has to go up to cover the transmission cost.

The whole point of this discussion is why isn’t one of them punished, and my position is that the other one should be punished. It’s not productive to simply say either one.

The CFAA is a law about crimes. Consider that. If a person gets killed would you say put someone in jail I don’t care who? Of course not. A functioning society requires us to determine exactly who to put into jail.
