Depends on the source and what you're trying to exercise. M-Code and spot beams are supposed to provide something like 20 dB of jamming resistance, and if your jammer is not right …

I don't think attitudes have changed on that. The last PM on my current project (in aircraft navigation) was a pilot, and he always stressed that a pilot in charge should have alte…

100 ms might be a good threshold for a lot of purposes, but for when refresh, 30 fps is painful to use compared to 60 fps: it is extremely noticeable when moving windows, but I'm o…

I think ripgrep does avoid allocations in that innermost loop. That's why this report says all the crashes are associated with opendir() and its memory allocation: the opendir() ca…

It got arm-waved to a race condition in munmap(). Claude (or a distill of Claude) didn't identify a race, it just convinced itself that was the cause.

I understand all the words in it and follow the argument, but it's still bullshit in the technical sense of being written by someone who wants to sound authoritative but doesn't ul…

> It’s the kernel. Nothing a user space library can do should ever be able to call this. I don't follow. An application might see this kind of crash if it has a bug causing it to a…

The ISO C definition of opendir() requires an allocation in practice because it returns a DIR* and it's bad practice for the library to arbitrarily limit how many of those an appli…

As long as the hardware can be used on newer models, hardware costs can be recouped running a future model. But if they're hoping to recoup non-recurring engineering costs rather t…

That's one of the nice features of jj: instead of having an index, the working tree is its own commit, and it tracks the history of that when you run most jj commands. This works b…

Not in every case. I would call (in the US) National Public Radio "public media", but Voice of America "government-run". I personally don't know enough about BBC or France 24 to go…

It means entering a personal identification number (PIN) as an authentication step.

Base 4 isn't substantially different from base 2 except in granularity. There's a somewhat famous result that base e gives the best expected density for representing numbers, but f…

The regressions got fixed before a release. Do you count your internal integration branch as "shipped"? 0.02 defects per KLOC is a low density, even considering that it was "just" …

The article is explicit that addition is O(n), with n digits, which is cheaper than multiplication is believed to be. Naive multiplication is O(n*n) -- considerably less than your …

> The AI can't decide on notation. It is sadly emblematic of how much SciAm has cheapened itself over the past decade. They used to care about technical details. Now they serve up …

Did Bun mass-close issues that predated the rewrite? It doesn't look like they did, as the oldest open issue is from 2021 and there are many from 2022, but maybe they did something…

> taking that into production with barely any announcement is what kills off the interest to me. Did Bun v1.4.0 release weeks ago and I missed it? I would call a formal release the…

I think the idea conflates price discrimination -- where people on individual subscriptions pay a much lower price per token than corporate accounts pay -- with using venture capit…

At the risk of stating the obvious, California's law only requires property owners to declare the presence of hazardous substances, not to reduce or even identify them.

I would suggest that if you have two similar copies of sufficiently complex logic, it's fair to combine them after they have been stable for a long time. My gut feeling is that the…

Yes, but California requires prominent signs for any business premise where these materials are found, and the incentives are to not provide any further detail about which substanc…

Go is similar: `for/range` has always worked on arrays, slices, maps, strings and channels, and they extended it to integers in version 1.22 and to user-defined generators in versi…

I've read the list of materials that California knows cause cancer and birth defects. It lists things that people encounter every day. Alcoholic beverages, aloe leaf extract and as…

Go is similar: package main import "fmt" var vec = []string{"the", "quick", "brown", "fox", "jumped", "over", "the", "lazy", "dog"} func main() { for i, s := range vec { fmt.Printf…
