Yeah. I keep coming back to Debian after trying out another distro for a while. There are some specific complaints I have about technical choices for Debian, like the way daemons autostart post install. But these complaints are outweighed b

Definitely agreed. Digging through Usenet archives, I found a post from John Mashey discussing the RISC-CISC spectrum. I found a copy here: https://userpages.umbc.edu/~vijay/mashey.on.risc.html The M68K gets called out

The way that shell builtins behave differently here is that SIGPIPE can take out the whole shell on the left side when echo is built-in. When you /bin/echo red, then it's a subprocess, and its parent shell continues on, so yo

I do think there are a few things that make the N64 kinda "special" for going back and squeezing more performance out of it. The 3D hardware is remarkably modern in some ways, but there are a couple very thorny resource limitation

While you might edit a long song down to a radio-friendly length, I think most songs start out short enough to be radio-friendly in the first place. 3 minutes is about the natural for a typical verse-chorus-bridge structure song. Cut out th

Whenever I've done analysis of classic popular songs, songs that I like, I'm always a bit shocked by how quick they tend to be. If there's an intro, the intro is often super short, like 4 or even 2 bars. Like you said, having

Apropos of Microsoft discontinuing Visual Studio for the Mac. My perspective is as someone who mainly used C# on the Mac with Unity. I was a professional C# developer at one point, but not on the Mac. MonoDevelop, long ago, shipped with Uni

You can see places in the Q2 code where it has been incrementally tweaked a bunch. The player movement code got a bunch of changes, and you can see blocks of it that are commented out or have #if 0. There are some comments explaining the th

Quake II was my first experience writing C. The code is clear, coherent, and straightforward. I’m not going to say it’s the best source code I’ve ever read, but it set a high bar. I’ve read source code to games since then, and I’ve seen all

That’s a good suggestion—I decided not to use MPW because the CodeWarrior compilers are better, the CodeWarrior UX is better, etc. For now, I’d rather drop 128K support and keep using CodeWarrior. The binaries work just fine on Macs with th

CodeWarrior ships with the source code for the startup code, but it is unfortunately somewhat long.

I’ve been doing some dives into Mac 68K programming recently, and ran into the same question—what about color on System 6? Like the author, I don’t have a Mac which is both color and runs System 6. The old Inside Macintosh volumes are somet

I’m very well acquainted, too, with matters mathematical.

It sounds similar to the division between “math” and “maths”. It looks wrong depending on where you grew up.

My experience with 𝔽 is “vector space over a field 𝔽”, which is not a concrete object, but I have probably seen F written in a normal italic style more often.

Thanks! I am always a little curious about how these symbols are used. That makes perfect sense to me.

by dietrichepp 3y ago
This is for math. In Latex, you get these symbols with \mathbb{}. They are most commonly used to represent to represent number sets, like the set of all integers Z (from the German), set of all natural numbers N, set of complex numbers C, s

I had the same experience switching to Dvorak. It forced me to relearn how to type, and when I was relearning, I made sure to learn properly. The switch, and relearning to type, 95% solved my RSI problems.

Note that this concept can extended to linear operators, which are the generalization of matrixes. Since it’s a generalization, some results for matrixes (finite dimensional operators) don’t hold for infinite dimensional operators.

Keep in mind that the information is old. http://www.paulgraham.com/carl.html I’ve read other stories, and seen presentations, but the information is getting harder to find.

To be clear, I’m not describing “editing live in production” as the workflow. The workflow is editing code live on your development machine, committing the changes, and going through the normal code review + CI/CD pipeline you’d set up

I’ve used that before, but the Lisp stuff still feels a lot better. I’m not just running a program and swapping out a function, but I’m using a REPL, some powerful introspection capabilities, a compiler, and a running system all together in

ITA software is an acquisition, and I’m sure most of the Lisp development at Google is just done by engineers tweaking their .emacs files. The problem of parsing data from airlines is fiendishly hard. There are a ton of different rules for

Maybe not of commercial value. But I took the time to get SLIME set up, with SBCL, and it seems like a completely different world. I’ve used languages with dynamic loading and REPLs before, and it seems like we still have something to learn

Yes. You can load the decompressed code into memory, mprotect() it to give it execution permissions, then jump in. Hard to do in a shell, though.
