I've definitely been guilty of wording my multi-line doc comments in a way that would ensure they'd flow without awkward right margins. I would have a macro in vim that would call the fmt program to reflow the comment to 79 (later

Nvidia's been pretty terrible for open source / free software. No need to quote Linus Torvalds here. They want to control what runs on their hardware. They want to you write code against their proprietary drivers and APIs, not dir

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 overflow. However, it's a bit of a gray area that the arti

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 considered an exaggeration. Even Windows 95 could run OK-ish on a sy

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 board.

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 undercuts some of the central points the post tries to make.

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 3.11 - 3.1. The result: 0.00. Try it! :-)

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 the kind of many-million volumes applicable for disposabl

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 a performance in London and one in St Louis. Still, it

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 try out the most contrasting way of transport: a Way

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. With 2048 my runs are far quicker.

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 transition, or ask the 1.8 million people who bought a Tesla last

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 matter where you want to go. Typically after 4 hou

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 these compare?

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 manager about your night classes and the need to cha

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 no influence on how it's used. For me, it&#x2

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 contract says otherwise, explain that you need to ke

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 computers to their will without programming. I didn&

Why not just keep the wire attached to the Yubi-key, but leave it electrically floating (high-impedance state) and have the board ground it whenever it needs to be pressed? No need for mechanical triggers...

Their goal is absolutely to drive down cost. Right now they're battery-constrained, so it would not make sense to sell them to third parties. If Tesla can only sell a given number of cars, it makes financial sense to sell them at a hig

Having been there, and having bitten often enough, I can confirm that most compilers just try to generate the most conservative code possible for volatile accesses. Their semantics are crazy/inconsistent, so you can't reason about
