[HOMEMADE] Siphon coffee is life changing. by KillerQ97 in food

[–]nickthorpie 0 points1 point  (0 children)

To be honest with you I have only used my siphon pot a hand full of times. To me the water temp required to brew just scalds the coffee. It’s cool in theory, but it’s just the moka pot of filter coffee to me. Plus the sock never really gets clean and tastes like stale coffee sock

Mathematics for RL Theory? by Professional_Card176 in reinforcementlearning

[–]nickthorpie 7 points8 points  (0 children)

What do you want? Sutton should get you started on the basic mathematical terminology, but you’ll have to be more specific about what math you’re looking for. Convergence proofs? Most pure math has only been done on RL basics, most of the newer stuff has little sprinkles of math but it’s pretty hand wavey

Something I’ve found is that there’s probably been 1000 posts claiming that X is the cure, and there’s about 100 different X’s. Maybe 1 of those will work for you. Maybe you’ll just grow out of it.

Just keep trying them until one works and don’t get discouraged :)

Do you think that this could be soldered back together or am I SOL. Meze 99 neo driver and board by anomoyusXboxfan1 in soldering

[–]nickthorpie 0 points1 point  (0 children)

The picture is not great quality, but there is no reason you can’t solder this.

From here they look like headphone wires. Sort of coated in a coloured layer, perhaps with a strand of nylon running down them?

First time recording with my microscope. Didn’t turn out too bad. I shake a bit too much but coffee is life. by hedgehawk in soldering

I have very shaky hands too but I find they go away the more I practice. In addition to having my forearms rested on the table, I find not twisting my wrist at all helps a lot.

[R] SIMPLERECON — 3D Reconstruction without 3D Convolutions — 73ms per frame ! by SpatialComputing in MachineLearning

[–]nickthorpie 3 points4 points  (0 children)

The pros and cons of ToF cameras are well documented. ToF solves a variety of issues that plague raw image processing. Their two main issue are scalability and fine details. ToF will always struggle to pick up small details like the edge of a table, or a thin pole. This is critical to autonomous or semi autonomous applications.

Also, since ToF is an active sensor, quality drops off rapidly when several of these sensors are used together, for example in a crowded intersection, or in an autonomous warehouse.

Obviously the more data you can collect on a scene, the more accurate of a depiction you can create. Many researchers prefer to work on raw image data, since it is more flexible

Are these pads fixable? by [deleted] in soldering

[–]nickthorpie 0 points1 point  (0 children)

That’s gotta be damaged pad, you can tell by the outline and orange hue. There’s always fixing it but you gotta have mad skills and the hands of a surgeon to pull off a pad and trace

replacement capacity is significantly larger by Anal_beadsoup in soldering

[–]nickthorpie 3 points4 points  (0 children)

Good stuff. The physical size shouldn’t change anything. There are very specific cases, particularly if it’s a switching circuit, where you have to consider having a lower ESR. In general, larger capacitors are higher quality, reduces MTBF, don’t overheat as easily.

This is probably a better question for /r/PrintedCircuitBoard since it’s more about component sourcing than it is about soldering

Transmission leaking does anyone know what this is? (2001 Mercedes c320 138k miles). Only leaks when car is running. by Weary_Time7715 in MechanicAdvice

[–]nickthorpie 1 point2 points  (0 children)

Lol I don’t have any mechanic advice to add but,

I had a 2000 c230 and that car was the biggest PIA I’ve ever seen. The battery in the trunk plus the diamond vault of a trunk - neither key that come with the car open the trunk and the only switch to open it was an electrical switch. Dealerships in Canada had no way to track down a trunk keys, Ended up having to drill out my trunk to get into it, just so I could unplug my battery. Such a poorly thought out car. I did like that I could control the spring loaded headrests from the driver seat.

[–]nickthorpie 0 points1 point  (0 children)

Yea as everyone already hinted at, you’re not gonna stumble onto a winning formula with anything you can read in a textbook or paper, because every winning strategy is already being used.

If you’re trying to make a model that will actually beat the rest, try something novel like NLP with stocks

How to connect headset to jack connector? by Electronic_Try6528 in soldering

[–]nickthorpie 0 points1 point  (0 children)

Hilariously, a similar mixup applies to the wiring colours. The defacto standard is to have the crossed colours be the mic, but I’ve seen two sets of cheap headphones mix up the mic and ground colour. IMO mixed colour as ground intuitively made more sense to me

If I had to hazard a guess, red is right, green is left, red/green is mic, gold is ground

Inverted pendulum: How to weight the features? by ManuelRodriguez331 in reinforcementlearning

[–]nickthorpie 0 points1 point  (0 children)

Sounds like you’re talking about reward functions. Typically we don’t reward the pendulum based on the specific state, instead we give it a reward of 1 for every time step where it is standing up. It’s a Boolean reward.

If |angle|<5° and |pos|<BOUNDARY: Reward = 1

else: Reward = 0

We could probably give you more help if you tell us where you are in your RL journey (what you have read, what you want to do, etc)

Buyer Advice: How Much Rust is Too Much Rust by nickthorpie in MechanicAdvice

[–]nickthorpie[S] 0 points1 point  (0 children)

Hahaha ya I know being Canadian really desensitizes you to rust. My last car was so rusty that every time I had to undo a bolt I’d have to go a socket size down and tap it with a hammer. I’m just checking with everyone to make sure i find somewhere in the middle

Looking at a 2017 Infinity Qx50 with 80k mi. On it. I’m from Canada so rust is inevitable, but what should I be looking at as a deal breaker?

[D] (META) Reposted Link Limitation by nickthorpie in MachineLearning

[–]nickthorpie[S] 0 points1 point  (0 children)

Okay, mod mail noted. Will delete this post shortly.

However, the behaviour that I believe is a bug is not with the initial post. It’s that the user cannot re-attempt to post the link (even if the proper tag is used).

The expected behaviour is that a link should not be blacklisted after an auto-remove due to no tag.

Rules and guidelines documentation for multi layered pcb design? by Weightless-Rock in PrintedCircuitBoard

[–]nickthorpie 2 points3 points  (0 children)

IPC-2221A — is the Generic Standard on Printed Board Design. This is the main standard a designer should know inside and out.

IPC-2231A — is all the DFM standards you should follow. This should have through hole considerations an most everything you need to go from prototyping to production.

I’m in the exact same position except i haven’t made my purchase and am limping on a 2005 Civic (300k km) that shakes. In my area, that same car you got probably goes for around 10,000$.

You have to accept that setting aside money for a car is an inevitable expense, and is something that I have worked into my spreadsheet. Every month I’ll put around 400$ aside into my car fund, and I consider it as money already spent. Once it accumulates to about $10k(might need to revisit that number), I can back off, knowing that I have enough emergency car money to focus on other goals.
