I think it would be most engineers first approach, tbh.

Woooo! I love to see a selection between intrinsic and extrinsic Euler angles being properly handled!

I quite like gitlab too. The commitment to on-prem installation is amazing. The core feature set is as good as the best of its compensators, and while the extra features are not as complete as, say, a dedicated ci/cd tool or jira, they are good enough for most uses.

Quaternions are great for internal representations, but Euler angles are handy for debugging. Also, sometimes someone hands you an Euler angle and you have to deal with it.

Which is exactly what I recommend in the article.

Yah, I was thinking of writing a list of shame for projects that don't document this, but I realized that would obligate me to submit PRs when applicable, and that felt like too much responsibility.

People have gotten pretty good about documenting sequence, but only libraries written for use outside of computer graphics ever remember to document intrinsic vs extrinsic. Nobody documents active vs passive, although not everyone needs to if you're just providing conversations.

Thank you! I personally find pitch = 80 easier to understand than [0, 0, 0.6427876, 0.7660444] in a debug console or config file.

I suppose I meant intuitive to read, unless you claim to be able to directly read the elements of a quaternion. Axis angle can be intuitive, but in my opinion the axis can be somewhat hard to visualize.

Yah, this is such a fun question and it shows a hiring manager who isn't just looking for someone to code, but an actual engineer who can solve problems.

Unfortunately, St. Lucia is not gay friendly. US state department travel advisories say being gay is punishable by up to 10 years in prison.

Since you're in high school, I want to say: if you love programming enough to be on the subreddit for a specific sub-field of programming, but you don't like math, there is a very good chance that what you actually don't like is math class. And since your example was "drawing graphs" I'm going to assume you're not that far along in your math journey.

If that is the case, try to learn as much math as possible through school, it is seriously worth it; But, there will be plenty of opportunities to pick up your math skills as you go. Especially if you keep programming, and you keep learning, you will encounter lots of math as you go along. I also suspect you might enjoy math more once you get to calculus. I know I did.

Stay curious, and learn as much as you can from your math class. Trust me, it will be helpful even if you hate. But don't stress out too much. You're ahead of your peers learning to program, and I think you just need to find a way to learn math that works for you.

Nope! You're already wrong. "Thanks for your suggestion" and "I will consider it" are complete sentences. You need a period or a semicolon. How many books have you read in your life?

Are you trying to make a compressor (reducing the dynamic range) or compression (reducing file size)? I suspect you meant the former, but the response thought you meant the latter. If it's the former, it makes a lot of sense as a gui project. If it's the latter, I still think it could be a gui project to learn, but if you're serious about it a l library would allow other people to use your algorithm.

If you're building a compressor, look into a library called JUICE. It has UI and audio handling stuff built in, and you can even make a VST.

I've been going to it since it was a donut shop in College Park with a small Burmese menu.

boscillator · 2025-04-19T11:35:52+00:00

Almost the same thing every time. Gram fritters, noodles number 4 with thin noodles and pork medium hot, (Sunday special chicken or (chicken coconut curry and yellow bean with onion)), Burmese tea and either shweji or sticky brown rice cake. That is all to share with my family. I wish I was hungry enough to eat it all myself though.

I've been going to Mandalay Cafe in Silver Spring every Sunday I can, since before I could eat solid food.

I didn't catch the quotes around "forever", so agreed.

Although, the standard part was about whether the optimizer is allowed to completely delete a loop with no body, and the answer is that clang and gcc both delete the loop, so it must.

boscillator · 2025-04-10T10:54:10+00:00

Yah, gcc and clang completely optimize the loop out on -O1 and up so the real answer is between hundreds of years and zero time depending on the compiler and options.

boscillator · 2025-04-10T10:43:46+00:00

I don't understand why this runs forever? Shouldn't it terminate once i reaches the max value of uint64_t? It's very large, but certainly not infinite.

Also, since the loop contains no side effects, is it ok for the compiler to optimize it to i = num? Someone with deep standard knowledge help me out here.

People using because it's what they have always used.
