What's not in my profile?

I used to be a huge Wirth-ian in the 1990s and spewed excellent tirades against the evils of C. Niklaus Wirth is also my "PhD grandfather" via Michael Franz at #UCIrvine.

I prefer lecturing sitting down in front of a laptop and talking while I do stuff on said laptop. I very much dislike slides and prefer chalk and blackboard for things like data structures.

I got my "15 minutes of fame" served unexpectedly:

But it still was fun.

I got my undergraduate degree from https://www.cs.hm.edu/ which back then was not allowed to feed into PhD programs. It's a thing in Germany: Everything is tiered and changing the tiers requires a change to the constitution of the republic (I am joking, but not really) so it takes a while. (Nowadays it would be easier to go on to a PhD from there.) The "plus" was that I spent two semesters in industry. In one I quickly out-FORTRAN-ed my boss, in the other I learned C++ from Stroustrup in two weeks while riding the bus. Beat that Ivy League!

I grew up on #c64 #basic and #mos6502 (well, #mos6510 I guess) assembly, went on to #m68k assembly, #gfabasic and lots of #oberon. Of course I was dabbling in #modula2, #prolog, #scheme, and more. Then it was mostly whatever I needed so #fortran, #cpp, #java, lots of #python, lots more #c, lots more #arm and #x86 assembly, some #golang, some #ocaml, some #csharp even if you can believe it. Nowadays it's pretty much #c all day with chunks of #python and bits of #rust now and then. And chunks of #bash too.

Considering how efficient Apple A*/M* CPUs are, do you think x86 is dead? Or it's just Apple's optimization that makes them work so efficient?
I'm using an Intel 12th gen and I hope ARM CPUs (or #RiscV 🙃 ) will be available for Linux in the next few years.

Learn something new every day! Today's lesson: a fundamental difference between x86 and ARM is how the return address for a function call is passed. The x86 CALL puts it on the stack, while ARM puts it not on the stack but in a register (Link Register LR, X30).

Now today's lesson comes from TAMUCTF2026, and it is about MIPS. There, the return address is also passed as register, just like on ARM. On MIPS, it's the Return Address register ($RA / $31).
