Signed integer addition is only associative when overflow is defined to wrap around like unsigned arithmetic. This condition is matched here, because only debug builds panic on ove…

I remember that EMACS meant Eight Megabytes And Constantly Swapping, a reference to the Emacs editor requiring a system with 8 MB of memory and then still swapping. It was consider…

The program terminated just a few moves into the game when there were plenty of legal moves left. Also, it is surprisingly hard to play chess as a human when there is no checkered …

I don't quite understand how multiply doesn't require addition as well to combine the various partial products.

The article makes it sound like the Tesla Semi is physically infeasible. Yet, it is in active use on a sufficient number of long-haul routes that ignoring this proof of existence u…

Can't help myself: whenever I see Windows 3.11, I have to compute the difference between it and Windows 3.1. So, I fire up the calculator from the Accessories folder, and compute 3…

How did you handle games where Stockfish would castle or promote?

For these devices the microcontroller needs to be super cheap. Microcontrollers like the Puya PY32 Series (e.g., PY32C642, PY32F002/F030) can cost in the $0.02 - $0.05 range for th…

I wonder if this will improve latency and signal strength

The title here says 100M, but the actual presentation says 1M?

That one has a special place for me. I was a consultant then and invited to join the chorus even though I wasn't at the more professional level the other cast members were. We did …

I recently visited SF with the fam. Besides riding the old-fashioned cable cars up and down, to and from, our Fisherman's Wharf apartment, it was a foregone conclusion that we'd tr…

This game is so fun! I spent entirely too much time playing it just once last night, and got to the 1024 piece in the first run. I don't know how long it took me, but it was long. …

I'm doing some fun chess-related programing during my sabbatical, and taking the opportunity to dive down rabbit holes I'd avoid for in a work setting. Found out interesting stuff …

A smart compiler would have used the test (x & (x - 1)) == 0 to verify that x (assumed non-zero) is a power of two. Don't know why Clang didn't do that here.

This article really confuses the problems that legacy car manufacturers have with switching to EVs, with EVs in general. EVs work, just look at countries farther ahead in the trans…

That's quite the bandwidth-delay product at 3.3GB.

Actually, that's mostly false. If you can charge at home, you'll have a fully charged car in your driveway every morning. With the Tesla charging network, you really can charge no …

It seems that the proposed system is an improvement over plants, but not necessarily over the Sabatier reaction driven by energy captured by solar cells. Is that right? How would t…

The new satellites will orbit the EU.

You probably work too many hours, and actually can more often say 'no' than you think. Delegate some of your responsibilities. Work smarter, not harder. Be transparent with your ma…

In many cases, software is like a tool. I provided a screwdriver: generally it's used for good, but sometimes it's used for assembling a bomb. By providing the screwdriver, I have …

In particular, if you're developing Free Software or Open Source Software, and a company wants to hire you, it is _expected_ that they're OK with you continuing to do so. If any co…

When I started studying CS in 1990, people told me that "programming" was a dead end: 3rd generation languages wouldn't require programmers and anyone would be able to bend compute…
