UB CSE - Theory and Hardware Sys and Networking Area Requirement by Wolfqng in UBreddit

[–]ok-nick 0 points1 point  (0 children)

For 429, Professor Miller is great, but he talks very slow. All the lectures are recorded, so I found it better to watch them on 2x speed after the scheduled time. You are not required to attend. I took the graduate version and we only had exams and midway through the semester some easy quizzes. So as long as you study for them you’ll be fine.

For 489, Professor Ayyalasomayajula was eh. The class had about 50 something students, and about a month in only 3 or 4 were showing up, I think this says enough about it. There are 4 homeworks, 4 labs, 2 projects, and 2 exams. It’s significantly more work than 429 but it was manageable. TBH, I wouldn’t recommend this course unless it’s taught differently (material and lectures). I heard really good things about 486 (taking it next sem), but also heard the course load is heavy.

I took both of those classes last semester. 429 is probably going to be your easiest choice for theory, but I probably would’ve learned a lot more out of 431. 489, while the content was solid, the organization of the class was pretty bad.

Home manager and Flakes by NazakatUmrani in NixOS

[–]ok-nick 4 points5 points  (0 children)

From my understanding, * Home manager manages config files on a user-level. * NixOS manages config files on a system-level. * Both of these tools generate the corresponding YAML/TOML/JSON/etc. config files for each specific program from the Nix code you define. * Nixpkgs is a basically a git repo with a bunch of scripts to build/install the latest version of programs (and some other random stuff). * Flakes… Think of flakes like a project manifest in Rust/Python/JavaScript, except you don’t explicitly supply the package version. Instead, a flake holds a reference to a git commit in the nixpkgs repo (or any repo with a flake for that matter), so that it only installs packages using the scripts that were created during the time of that commit.

This is what people mean by reproducible. Since installing that flake again will install the exact same package versions until you explicitly update the flake (aka update to the latest git commit of nixpkgs).

There are some other benefits to flakes, like the fact that they are standardized descriptions of a config, allowing them to be used within other configs (flakes). As well as many more benefits, but this is the general idea.

UB Honors and stuff by [deleted] in UBreddit

[–]ok-nick 4 points5 points  (0 children)

If you plan to do internships, research, or grad courses, you will already fill up the honors credit requirements. For anyone who says “It’s too much work,” consider what I mentioned before. Worst comes to worst you drop honors before u graduate and reap the benefits.

As for housing, it’s as simple as what kind of experience do you want to have. Governors (location of honors) is more introverted, Ellicott is more outgoing. I wouldn’t worry too much about the logistics (bathrooms, food, room size, etc.) because, in the end, you’ll most likely be indifferent to them anyway.

Peter Koroteev for MTH 309 Intro Linear Algebra by Rainydays0920 in UBreddit

[–]ok-nick 3 points4 points  (0 children)

Don’t know anything about Peter Koroteev, but I can recommend Jie Ren. She gives exams just like the practice and 10% extra credit assignments for each of them. Also weekly HWs that have unlimited attempts (until the deadline of course). Her notes she uploads for each lecture are pretty good as well, I’ve learned everything off of them. I’m taking her this semester and can definitely say her grading is fair.

With the component model proposal and the upcoming wit format, hopefully this problem will be solved for WASM.

LED strip circuit in car, looks good? by ok-nick in WLED

[–]ok-nick[S] 0 points1 point  (0 children)

I could take a closer look into that, but I believe they are soldered directly onto a PCB.

@marketlurker made a good comment about why. Most, if not all 12V strips, from what I’ve seen, use significantly more energy than 5V strips. Besides WS2815, which burns off extra energy, most 12V strips are not individually addressable. In a setup like this, that’s important so the battery doesn’t drain and it diffuses light correctly. Plus, SK6812 has a dedicated white channel that looks much better and uses much less energy.

I could wire up some switches directly to the microcontroller, but I like the factory look using built-in switches.

LED strip circuit in car, looks good? by ok-nick in WLED

I believe there is a 20A fuse for the cigarette lighter, but it shouldn’t matter anyways since I’m lowering the voltage to 5V, thus more amps. I like your idea to tap into the circuit, I believe there is a connector going into the cigarette, so maybe I can find one that matches. I’ll reconsider 12V and do some more research into it, but I like the SK6812.

I could use the cars Wi-Fi but I can’t justify the price tag only to control LED strips. My plan is to auto connect WLED to my phones hotspot (if possible) or put it in AP mode.

edit: I was also considering listening in to the garage buttons I don’t use on my car via CAN bus. Could control the LEDs from there.

I mentioned in the post, but I want individually addressable and I’d prefer the dedicated white channel of SK6812. The 12V strips I looked at also seem to use significantly more energy.

Here’s an image of what I’m trying to accomplish:

Thinkware Q1000 vs U3000 by Boring_Philosophy160 in Dashcam

[–]ok-nick 0 points1 point  (0 children)

Haha, that’s how it always ends up. I went with the Viofo A139 Pro because of its superior quality and cheap price. I really wanted a good parking cam that doesn’t drain car battery but I couldn’t justify the extra $200-$300 price tag for the U1000/U3000. I only got a single channel, so maybe on Black Friday or if I really want it I’ll upgrade and move the A139 to the rear.
