The question of "why" is important here.

One could make a LED bulb by buying a E27 "plug", an LED, making a PCB with the power supply for the LED, putting that together and attaching a cover of some sort. It will be one to two orders of magnitude harder to make than an LED bulb made serially.

I don't know much about processes needed to make a filament bulb (at the very least that requires working with glass, but I don't even know in which order such bulbs get assembled).

So, if you just want a working bulb, I'd probably buy one. That need not be the case if you want to figure out how to make a bulb and are fine with having to make a few of them before they are good enough (because you'll learn about random important things along the way).

(Oh, and don't even try to make fluorescent bulbs. They are nasty in all ways I can think of -- require nasty gases inside, high voltage, can produce UV incl. UVC that needs to be filtered out lest they damage eyes of anyone nearby pretty quickly, ...).

@freeschool What kind of bulb? Incadescent (with a glowing filament) or some other?

@freeschool I'm sorry, I can't understand the question. What does your spotlight need? What do you mean by making your own bulb?

You ever wonder if toothpaste is more of a lapping compound or is it more of a soap?

I'm really surprised that E27 lightbulb sockets are considered fine for multi-kV voltages (there are sodium vapor bulbs without an internal igniter that have that base and require upward from 1.5kV to ignite).

@rysiek

That said, solving that problem would not necessarily be a solution for the original issue:

Imagine that you have a hypothetical training procedure that always converges on some subspace of models with a uniform distribution across them. Imagine that 0.01% of that space is malicious in some way. Then there is no difference in probability density between the (very small) malicious subspace and the rest of the potential outputs of training.

Figuring out that the model we have is specifically chosen to be from _that_ part of the potential output space requires some understanding of how that part is special, and if we have that understanding we can ignore the question of whether the model came from the known training process.

That said, finding a malicious model _that is also a reasonably probable output of the normal training process_ might be computationally hard, or might be impossible (I don't know if people have tried to find adversarial models under that additional constraint).

@rysiek

The training procedure involves randomness, so if you do it from scratch you will not get the same thing anyway.

@rysiek

That sounds like an interesting question: given a training dataset, how likely a particular model is to result from, say, SGD on that dataset (or as a result of any other known training procedure that involves randomness)?

@isomer

Sv being J/kg is kinda a lie on that chart: it's more accurately the amount of radiation that would provide biological effects equivalent to that amount of some standard spectrum.

I don't really see much of a difference between starting with time and frequency: we define all of that by "one period of <some lightwave>" anyway, so we essentially start with frequency. We also divide by units of surface area in quite a few places.

Re charge: amusingly 1 mole of electrons is something like 96 kC.

Hm~ I would be surprised if it actually went _under_.

Also: Schildkröte (shield toad == turtle), Regenschirm (rain shield/screen == umbrella), Fallschirm (fall shield/screen == parachute), Glühbirne (glowing pear == lightbulb), Wasserstoff (water substance == hydrogen), Sauerstoff (sour substance == oxygen), Frauenarzt (woman doctor == gynecologist), Seehund (sea dog == seal), ...

@adriano @dan @ZachWeinersmith

Or descriptions of ways to affect some important property (e.g. "to increase stickiness add eggs, to decrease it add water").

@LesterHammerer@mindly.social an approach you might not have considered is to find a package forwarding service in the EU, have the bookstore ship it there (I assume the shipping costs would not be absurd for shipping to within EU), and have them reship it to US.

@lauren they are also peculiar: both depict people reacting to similar events, but claim that they affect them in ~exactly opposite ways.

I also prefer the movie version, but am unsure if it's not overly optimistic.

@lauren interestingly, the book it's based on has roughly similar events, but very different attitudes/thought processes of people. (I am being somewhat circumspect to avoid spoilers.)

@mcc

How is the following relationship related to ability to DM someone?

@freemo

You might wish to know that UK has a similar attitude to anything with a blade.

@sophieschmieg @0x2ba22e11

You can brake in Sun's atmosphere, so you "just" need to get to an orbit with low enough perihelion. That doesn't change the conclusion though (I think? ISTR that bielliptic transfers work similarly for elliptical source and destination orbits, but Wikipedia says nothing about that).

@b0rk

I am doing such merges constantly :)

I have a checkout of nixpkgs, and sometimes have a few unrelated PRs open. I want my system to use a version of nixpkgs that includes all my changes. Thus, I have a script that finds all the branches with my PRs and makes a merge of upstream/master with all of them.

I never push that merge commit anywhere and never commit anything on top of it; it's just there so that I can point my nixos flake at a version of nixpkgs.
