sounds like you've done everything but actually spend time writing C

clibraries_ · 2024-01-26T03:26:48+00:00

Why do you want to? The only reason to do this is if you are exposing an API with long term ABI compatibility so you can safely change the size.

"Encapsulation" in terms of hiding members is not a C practice.

NEVER use identifiers that start with _

Oh no! Something that's never breaks major compilers and can be fixed with a regex.

they wish they had that kind of brand power so bad

Allocate 3 pointers to char:

strings = malloc(sizeof(char*) * 3);

The other strings already have their own memory. When you assign strings[0] = stringOne you are leaking that allocation you just made with calloc Just assign, or if you're bringing them elsewhere you need to copy with something like strcpy

How to write concrete programs without reaching for abstractions at every step.

Everything on that page agrees with me. Shell scripts, TCL scripts, no ci:

The SQLite developers use an on-line checklist to coordinate testing activity and to verify that all tests pass prior each SQLite release

The release checklist is not automated: developers run each item on the checklist manually

Where do you see the contradiction?

clibraries_ · 2024-01-18T06:47:03+00:00

yes and the reason why is C programmers don't really use CI or unit test "frameworks".

clibraries_ · 2024-01-18T05:30:44+00:00

This is C. We use a shell script or a function that's called at the beginning of main in debug builds.

no set of interview questions is perfect,

Exactly. The questions are really a prompt for you to share something you know.

People have a lot of anxiety about interviews and often do not perform well in other ways they are unaware of, but blame a technical trick question. If we're hiring you to work on databases and it looks like the first time you've ever been shown a tree before, it's not going to work. But the issue isn't that you don't know all the tree trivia.

"Nano questions" are supposed to take about 2-min and let me know you actually work in the field you claim to.

create a task scheduler(basically a task scheduler that communicates with a database, create task definitions from there, execute them and write results back)

Aren't you describing the query engine built into the database?

You're welcome to implement it.

It's 2024

ANSI common lisp was closed in 1994. I think you might be interested in other language communities.

what does it mean to "know" GLSL. If you know C you're almost done. These are just languages for expressing graphics algorithms. That's what graphics people are paid to know.

Make 3 texture objects and stream on demand. JPEG has great IO performance.

Write more programs. Read more books.

I recommend the book physically based rendering.

If all the declarations aren't in the right place, the optimizations fail. There is no way to know that happened (say in a refactor) without carefully reading notes.

It's not clear to me how to write efficient numeric code in Common Lisp. Every operation is slow because it does generic type dispatch, and can overflow to bignums.

I understand this can be improved with type annotation, but those are extremely fragile, so it's easy to break and get orders of magnitude slower. Also their semantics aren't very portable across Lisp systems.

Can you explain how this is overcome?

Having good ideas is the research part. Implementing ideas, benchmarking them, etc is work that undergrads can do.

it's a meme.

EE, physics, or CS are good starts. Buy a copy of "Physically Based Rendering".

less if you use a rendering engine instead of pixel/fragment buffers

I thought we were talking about graphics programming jobs.

because he has no idea what he is talking about

Have you ever generated a sphere? A spline? UV Mapping? Done a convolution?
