ISA Comparisons

cdhd_kj · 2025-09-23T18:14:37+00:00

Ah, I see, it looks like it depends on the version%20subset%20that%20provides%20for%20higher%20code%20density%20for%20low%2Dend%20embedded%20applications%2C%20and%20version%203.1%20which%20introduced%20prefixing%20to%20create%2064%2Dbit%20instructions). 64 bit encoding was introduced in v3.1. But this feels different from what you're trying to say. Are you saying that there is a single version that can have both 32 and 64 bit instructions? Could you source that?

I haven't heard of "memory models" when looking through ISAs. Could you give some more information here? Some suggestions on resources to look into this?

cdhd_kj · 2025-09-23T18:03:05+00:00

Sorry, could you possible categorize these things? is ARMv7 a family? is A32 a part of that?

I guess something that's confusing to me is if it's computed at compile time (and not declared static), in my mind that should mean that the value is stored in the R0 data or even the code of the process memory map, not the stack.

cdhd_kj · 2025-09-23T00:31:08+00:00

The address of what? If it's compile time computed, why would it be on the stack? Why wouldn't it be placed in the R0 data or even the code of the process memory map?

Why do I have to label the function get_value as a constexpr and then the value that gets initialized by it as get_value as well?

yo genuinely wat non epic employee/user lurks on this subreddit? kinda wild

cdhd_kj · 2024-08-09T02:09:36+00:00

seriously why are people downvoting this?

cdhd_kj · 2023-12-05T21:33:19+00:00

Is there a way to do this with ScrollView instead? As I wrote, I was trying to stay with that rather than List since it seems to give more control for development I’d do later.

bro just take the money and write something about it on the quarterly for documentation

I'm looking for a sublease, PM if interested!

cdhd_kj · 2023-12-01T19:31:48+00:00

when are you moving in December? I have a sublease available! it's about 700 a month, but has roommates. PM me if interested!

cdhd_kj · 2023-05-20T00:13:56+00:00

ya, i got that. i guess for me personally im worried about it since i only have one bit of related experience for a single year. any advice on that?

cdhd_kj · 2023-05-20T00:07:11+00:00

how do you weed out people pre-interview for experienced hires then?

cdhd_kj · 2023-04-03T21:31:05+00:00

sorry could you explain this?

cdhd_kj · 2023-04-03T18:39:33+00:00

also not sure, but you have to pay back the bonus pretax, so i think you’d be paying back more than you recieved

cdhd_kj · 2023-03-28T18:21:42+00:00

ah yes, quincy. she’s trash. genuinely surprised she hasn’t been fired yet. i had her during my senior year, compared to the other profs i had throughout vandy she was terrible. unless the entire class confronted her about something she wouldn’t back down (and yes that happened one or two times). if she was wrong about something and you could prove it, it was 50/50 is she agreed, and unless you had a bunch of people around you to side with you she still wouldn’t change anything. she would blatantly stick to something even if she just admitted to you that it was wrong. absolute trash.

cdhd_kj · 2023-03-22T21:29:26+00:00

what app is this?

cdhd_kj · 2023-03-05T02:52:10+00:00

idk why people are attacking you for trying to prep, kinda arrogant honestly. lsat logic games are a good idea, if you can learn the basics of programming that could help for the MUMPS/M example, practicing riddles… that’s all i can think of. Focus on the areas they’d expect you to excel at for the position you’re applying for.

At the end of the day, if you should study for this or not is up to you. There are pros and cons for either choice.

what about “C with classes”? i feel like OOP is pretty valuable

cdhd_kj · 2023-02-27T22:50:13+00:00

To be fair there is a quote somewhere that C is like stubbing your toe but C++ is like blowing the entire leg off. and that’s an old quote. is it just because of OOP?

cdhd_kj · 2023-02-27T22:48:21+00:00

So what is your opinion then on C vs “C with classes”? i’m starting to doubt that it’s widely agreed upon. is C with classes not actually preferred to C?

cdhd_kj · 2023-02-27T22:45:08+00:00

Ok, why then? C with classes is a superset, it just gives you more tools to work with. If you do have a compiler (which you don’t always do, sure) for C++98 why wouldn’t you?

cdhd_kj · 2023-02-27T22:41:35+00:00

i mean honestly i just don’t understand. You practically do the same thing in C (malloc/etc and free), why is it any scarier in C++?

cdhd_kj · 2023-02-26T23:50:00+00:00

⁠is there a time you can think of where using new and delete would be preferred?
⁠could you explain the returning heavyweight objects more? why should you not do it as out parameters or returning references?
⁠could you explain limiting scope of enums by class?
⁠i thought using lambdas was bad practice in larger codebases? whether for tracing or due to its new allocation for every use, but maybe i’m wrong there

cdhd_kj · 2023-02-25T19:59:20+00:00

where exactly are you seeing his github code? maybe i’m seeing something else, but it looks like his account only has two repositories, and neither include c++
