Rea posted:inexplicably had us learn MIPS assembly, Not that inexplicable for a low level course. MIPS has been used for teaching assembly for ages because it's a nice, simple, clear and basic RISC without many bells and whistles. These days I would probably prefer 64-bit ARM but a) that's a recent thing and b) university courses move slowly. You probably don't want your first assembler experience to be x86. Or if your complaint is learning any assembly - if you are working at a low level, it is a good idea to know what your C is actually going to end up being once it comes out the other end of the compiler even if you aren't hand writing assembly (and if you're doing a lot of kinds of embedded work you may be doing that and you will definitely find it useful to be able to read it). feedmegin fucked around with this message at 12:13 on Oct 6, 2022 |

Nah, I think learning any ASM at all was a good idea--like you said, knowing what our code actually compiles down to is valuable. It was just very strange to me to learn MIPS in specific, in 2017. In hindsight I think it's partly what you're saying, partly that SPIM made it easy to actually execute our work.

My assembly class in 2003 or so used some janky 68000 emulator that could only run on the lab computers and crashed not-infrequently. It was a real throwback to the days of writing out programs on paper first before touching a keyboard. Pleasant syntax though!

My first intro to assembly was a carefully chosen subset of the x86 instruction set. It's not that bad if you ignore most of what it has to offer.

8086 didn't have that many instructions, did it? We did learn its assembler in 1998 or so at university and we turned out fiiiine. Adding the 8087 co-processor wasn't that bad either.

My first experience with assembly was learning about the other, secret graphing calculator language that was how you made the good games. Learning about assembly on the Z80 while using weird reverse-engineered headers and accidentally learning about hexadecimal at the same time was a bit weird. I had binders of printed source for ZTetris/Galaxian/etc.

Sure, but it's a bit of a poo poo way to learn assembly in 2022? That thing is long obsolete and doesn't map too closely onto how you write modern x86 let alone anything else.

It also happens that most code generated by compiling integer code also uses a limited subset, too. No reasons to touch the MMX mnemonics in particular unless you're trying to summon the elder gods.

I learned x86 assembly when I was at summer camp. The closest I got to writing a game was getting a square to wrap around the screen when you pressed the arrow keys. Inexplicably, I found assembly boring and was far more interested in playing the unreal tournament 99 beta. Not much has changed since then.

Limited instructions, pretty widespread 32 bit has some oddities (conditionally executed everything, barrel shifter) which were removed for 64 bit. And that's classic in which case MIPS works just as well). I wouldn't start people out on Thumb.

I just spent a couple of weeks teaching assembly to second year students. We used RISC-V. Quite nice and simple, and decent tools and resources are available. It would be tedious to write big things by hand because it is so RISCy, but that's not a problem for teaching.

The two big advantages of MIPS over a x86 subset for an intro to asm is that it has 32 registers and you avoid the whole at&t vs intel syntax thing. RISC-V does seem like it's probably the way to go these days but there isn't exactly a pressing need to switch over.

There were two teachers for that course, and one of them - inexplicably- did not allow the extended branch mnemonics. So you couldn’t use BGE (branch if greater than or equal to) or BLT (branch if less than), she only permitted the use of BCC (branch on condition code) which took a bit mask like argument to determine whether you were checking less than, greater than, and/or equal to. Made the code far less readable. Thankfully, I had the other instructor.

I pretty much learned z80 from a series of 3 articles in Amstrad Action, and I built my own assembler out of basic because I never had a good memory so remembering how to translate mneumonics to bytes just didnt work for me. That said, as kid written code, I suspect most of that would fit under the "coding horror" category. That shits burnt into my brain. nearly 40 years later I can still more or less read z80 and I can probably with a bit of a refresher, write it too. My C64 enthusiast friend says the same thing (Although he's *still* hacking away on that gnarly old beast. I havent seen an Amstrad in 20 years, though I've always fancied buying one, just to gently caress about with the old games and show the kids how real "8 bit" games look). Those 8 bit microprocessors where great little things, simple enough for a child to learn it, quite literally. duck monster fucked around with this message at 03:16 on Oct 11, 2022 |

Falcon2001 posted:MTG Arena is sort of the 'example' end of the coding horror spectrum so I think that it can go here too :p On the one hand, it’s kind of impressive they managed to cram all the interactions into an engine that is consistent and quick, and got the software out the door in something like 1.5 years. On the other hand, they plum forgot to add any ability to spectate matches in their uh, hopefully budding eSports client or any support for multiplayer whatsoever, their most popular format by far.

My only exposure to any kind of assembly has been trying my hand at debugging through a SNES rom in an emulator, to try to figure out what it was doing with some of the data in the ROM that I knew was level data. (I managed to figure out that the code was decompressing the data, which was compressed using a variation on the LZ-77 compression scheme) (I was thinking of making something to allow you to randomise aspects of the rom but I never got anywhere with it, because these days I can't stick with a personal project for any length of time without losing interest)

Then there's all these little UI things that work really well, because if it's in the core game they have to. I recently had to use the UI to cancel someone's attempt to cancel my cancel spell, it showed the entire stack as it was, with my cards closer to me, theirs closer to them, and asked which one I was trying to cancel. I had a spell that would exile something from a graveyard, someone's deck was picking stuff from the graveyard to go back to the hand/library, when I'd trigger my ability it would highlight the card they were trying to pluck and made that default choice extremely easy to input. There's weird corners like that where they definitely had the right folks solving it.
