You can definitely do this without sorting. QuickSelect is average case n, and is, roughly, quick sort where you throw away one of the sides each time and recurse on the other. This has a fat tail for cases where you pick a bad pivot (simil

I used to translate classic interview questions into not-spoiled-on-the-internet ones by doing this kind of batch to incremental conversion. The count-the-islands one was fun but hard to fit into a 45minute interview. Eventually most of tho

Split locks are weird. It’s never been obvious to me why you’d want to do them unless you are on a small core count system. When split lock detection rolled out for linux, it massacred perf for some games (which were probably min-maxing sin

Popular blogger from roughly a decade ago. His rants were frequently cited early in my career. I think he’s fallen off in popularity substantially since.

This is more of a typing game than anything else. It rejected “blackcapped chickadee” (wanted black-capped chickadee). Frankly that felt a bit tedious on a phone. Had to scrub through to correct and lost.

My suspicion is that the bot was a fairly standard chess bot, but the difficulties were set based on computation time. As airplane computers got better, it turned into a beast. As a result, if you tried this on older planes, it might have b

For my personal usage of ai-studio, I had to use autohotkey to record and replay my mouse deleting my old chats. I thought about cooking up a browser extension, but never got around to it.

How much are my eyeballs worth over the lifetime of a TV? In the race to the bottom, ads will outcompete others by pushing price lower. But how much lower?

Legitimately, they are often too hard. Balancing the problems is quite challenging. On top of that, the solutions often make the problems seem much intimidating than they are (not that they are easy). Most solutions involve a lot of “happen

Source for the ASP firmware is at https://github.com/amd/AMD-ASPFW . It has a number of gaps, but it is mostly there. It doesn't build, it doesn't have source for some of the service calls iirc (SVC_.*), and t

In practice, it’s essentially infeasible to make a non-detectable virtualization stack. Timing is really really hard to match (as is everything else). You can edit the binary that’s doing the detection, but this is time consuming. Every new

Allegedly some of the anticheats are configuring the IOMMU through Windows APIs (vanguard, faceit, and a smattering of chinese anticheats). It’s hard to find good public information though. They do some mix of blocking access and deliberate

Cheating will slowly look more and more like trying to hack your own machine. Secure Boot+TPM combined with decent firmware will make cheating a lot harder. If the firmware ensures random devices don’t get BME set before the IOMMU is proper

With the default key hierarchies, the benefit is more limited. It raises the bar. Implementing known vulnerabilities takes work. And not ever configuration is vulnerable to every issue. And, for a lot of the vulns, the OS vendor shoves thin

Tried cheating with Gemini 2.5 pro, and I became even more suspicious to the AIs than the stuff I cooked up by hand. Most of my actual success relied on mentioning a desire to train an even larger model.

The most interesting toy economy I’ve seen has been d2jsp and its “forum gold”. Forum gold is primarily used as a fiat currency for diablo 2 trading. It’s a janky digital currency on a janky forum from like 20ish years ago, that’s still ali

Had the same experience. Took the janky decompilation from ghidra, and it was able to name parameters and functions. Even figured out the game based on a single name in a string. Based in my read of the labeled decompilation, it seemed larg

You are probably saying this as a troll, but I’ll bite. I mean, sure Rust would have helped. Technically, the borrow checker and bounds checks wouldn’t have done it here (I’m aware I’m being obtuse by not just linking the bug). Having clean
