The leap day system handles the mean, the leap seconds handle the variance around the mean. The need for leap seconds is not predictable—they zero out accumulated error.

My attitude has always been that code review is best thought of as the gate where code goes from being owned by the author to being owned by the team or project. The code I'm revie…

The diffraction limit (under 1.22 h* lambda/d) of a 1m optic at 250km in visible light is about 17cm. How can you achieve 10cm resolution?

At least a few years ago (~2014), the fare search was actually nearly instant, but all major airfare search sites added a delay because customers had the impression they were getti…

I’m not sure why people are making a big deal of it. At my gym it took maybe 3 minutes. You tie a knot and show you know how to take up slack. And it only needs to be done once. Th…

When you are modifying a long closure and don’t notice that you are shadowing a variable that is used later. I know “use shorter functions” but tell that to my coworkers.

The worst part is that the sales person has to go back and pitch their team on whether it’s worth their time to get back to you.

Really curious about this: > If you have access to a program named 'Purify' ... learn how to use it. Anyone know what this was or use it?

“10x price hike” would have been totally clear. “Factor of 10 price hike” would probably be a formal way to say it.

The Debian images ( https://raspi.debian.net/ ) haven't been updated recently and don't support the Pi 5 at all. And support for other hardware is inconsistent.

How is this any different from going into a Panda Express and trying to order in Mandarin?

I think it helps that the technical concept that drove the main plot was a very real and still-present risk to public key encryption systems.

In benchmarks, branch predictors guess correctly 90-95% of the time.

It seems like every article about nix goes on and on about DLL hell. I've been using Debian/Ubuntu for 15+ years and never really experienced dependency hell. I guess maybe this is…

Note that his tweets indicate that he does not believe it to be an ASAT test. https://x.com/planet4589/status/1806333953617334688

I think the problem is that often the order you want it in a clean history is not exactly the chronological order it was developed. Eg you may build out a feature vertically, tweak…

The main issue is that on a longer branch, you have to fix all the rebase conflicts on the oldest commit. Then, if you changed something in the conflict zone, you fix it again on t…

Moon phase is caused by moon position.

if you don't know what commit is good, just go way way way back. Go back 10,000 commits instead of 1,000. The magic of bisection search is that opening your search window by 10x on…

Fuel mass is very much the limiting factor. "Electric" or "ion" propulsion of this general type are used on satellites for things like orbit raising or orbit maintenance. They don'…

This is exactly right, except that whenever there is a deviation there is a side channel conversation of "How can we fix this without needing to do all this paperwork, while still …

It's a suspicious claim as well, a perfect score on GRE math is only 94th percentile.
