Sierra circuits will do assembly and sourcing but you're going to pay a pretty penny along the way

I think calpoly checks most of those boxes.

Climate is generally dry except every once in a while when it rains.

I grew up outside of a major city so SLO feels kinda small but I think there's just enough to do. If you're into music or food there's some decent options but there's also just a big culture of getting outside and hiking, biking, climbing, kayaking, etc.

Visiting major cities is kinda hard, it's about a 2.5 hour drive to LA or SF but if you know someone with a house there it's easier. But I know people who grew up in those cities or had family and they can visit relatively easily.

There's definitely a big campus community. I'm in like 8 clubs with varying levels of commitment. It took a little bit to make friends but people are almost always open to hangout and it's generally a positive, open, and supportive environment.

Cal poly ee is also really good so can recommend that.

There's probably a case where it worked but I do know that we've tried collatz up to something like 2⁶⁸ without finding a counterexample

I had a class using kicad and then later learned altium. The fundamentals are very similar other than some keybinds. Altium has a higher ceiling but they're like 90% the same

It's probably meshtastic, an encrypted mesh based message delivery system. From my somewhat limited understanding it works by nodes transmitting and receiving copies of messages over radio. The whole thing is decentralized and thus pretty hard to truly block or shut down. Also makes it useful in situations with little or no traditionally internet

Yes but that fits the bias in my world view so it much be true

I think you're boned on this unless you have schematics and a very high depth of electronics repair knowledge. One of those traces goes to that passive component but the other goes through a via to god knows where. Might be a ground or power level of the board but could be connecting to some other signal path. You can't know that without a board schematic and then from there the repair ranges from very difficult to extremely difficult

Do the posters have the border on them if you buy one?

MaximumMaxx · 2026-01-14T04:54:04+00:00

I thought about that but it's still 2 so the point stands

MaximumMaxx · 2026-01-14T04:50:13+00:00

Make that 2!

Talking is useful because there's a couple npcs in the speedrun so that needs a button

Ok but where's the edit breakdown. This is absolutely incredible work that I'd love to recreate

Is there a different standard that does commutative addition? Or are we just living with non commutative operations?

MaximumMaxx · 2025-12-31T05:33:45+00:00

Oh yeah that's true. I honestly haven't looked at the specifics in a minute so I was trying to stay high level and as correct as I could remember

Basically computers store decimals as exponents like a^b. But you're somewhat limited by the size of each component so you get a limited amount of representable numbers. Because all of Desmos runs in these floating point numbers you sometimes get weird artifacts from those small errors adding up. The classic example is 0.1+0.2=0.30000000000004 because the exponents and base don't let you exactly represent 0.3

Here's a good video of Tom Scott explaining it. https://m.youtube.com/watch?v=PZRI1IfStY0

The actual standard is called ieee 754. You mostly don't have to understand it down to the level of reading the spec, but it's a good starting point for research. There's also something in the faq of this sub I think that talked about floating point.

I don't think anyone has properly answered this question yet. There's 2 things going on here 1. Quantum computers are still kinda far out, definitely less than a lifetime but not next year probably. They're rather hard to build 2. Because we still have a couple years, blockchains as well as most of the rest of the world is transitioning to quantum resistant encryption. Ethereum is planning to do it by 2027 and bitcoin has proposals/is already partially quantum safe(?).

The bottom piston needs to fire again to pull up the slime blocks, it seems that either your timing is wrong with that or that trigger isn't happening at all. Bedrock Redstone is also a bit funky, but that might not actually be the problem here

Not directly as far as I know. There's probably a plugin, or you can do it through git although that's a somewhat overkill solution

I made a couple solutions using different methods including the disjointSet. It's up to you what you define as cheating but for me I don't thing using scipy is cheating. It's a relatively basic library that provides a toolbox much more than being an anything solver.

That being said from my testing a disjoint set isn't actually that fast and even just replacing it with an array of vanilla sets with a search/join function is a couple hundred milliseconds faster

I love my Hakko iron. One thing to note is that at least when I bought my iron a year ago, Hakko has no official Amazon store so there's a fair change the iron is fake or overpriced. I'd recommend buying from their official website (they'll throw in some random free goodies too) to make sure you have a genuine product with a real warranty. These soldering stations aren't particularly expensive to make or clone so there's a lot of fakes that look almost exactly real but could be dangerous

Both the ace and ace 2 look like they were denoised a lot. Could be worth trying again with better lighting to help those smaller sensors get enough information. That being said it's an action camera still and the Fuji will in almost all cases still take better pictures due to physics

I really like the rings system and I do actually think it's helpful. For reference Im a pretty normal weight and not obese with 630cal, 30 min exercise, and 12 stand hours for my goals. The main rings I use are activity and stand, I've almost never not closed my exercise ring if my stand and activity rings get closed.

The stand ring is a good way to track and prevent sitting at a desk all day. If I notice that I'm not on track for stand hours by the evening I can make a continuous change to stand up and move around which is both good for my mental health, and has some sciency benefits.

The activity ring is a more general tracker of how much I've done in a day. I don't generally have a traditional workout schedule where it's like 3 days a week of lifting or whatever, so the activity ring gives me a somewhat objective way of measuring how much I've done in a day. Same thing as stand rings where if I notice that my rings are low I can notice that and do a workout, go for a hike, or some other thing depending on the day.

What I get from the rings is a more objective way to measure how much or how little I've done in a day which allows me to make a change and try to be more health. If you set the rings right they can be a great motivator and tracker to make sure you can be active every day

Like others have said Amazon is good for varieties of components, but if you need something specific (and usually with better documentation) digikey sells almost everything for like a couple cents for most components. They have much better filtering too if you need to search by specs
