Is this the “stop saying brave when you mean racist” joke?

It’s the other way around, as a recent leak of our government’s communications has shown.

What a non-negative thing to say.

He’s good at promising without delivering, which is great if your idea of government efficiency is “have the best press while embezzling tons of money”.

wine control launches Wine’s sparse control panel (most options are under winecfg). You can use it at fancy parties for fun tricks or to make someone puke.

Reroot tree: Tree digs itself out of the ground, walks to another location and takes root, as if it’s always been there.

Heap sort: More advanced technique for which Reroot tree is a prerequisite for some reason. Arranges assortments of things into neat piles with only one kind of object per pile. Very useful when looking for things in treasure chambers.

Better make the URL memorable such as https://library.example.edu/restricted (you can always make a redirect) and print it next to the code. Some people might not want to be seen scanning it, and it helps accessibility either way.

My Blåhaj is basically a bed accessory

I saw Big Clive and DiodeGoneWild take some apart, and we had been using halogen or fluorescent ones at home because LED bulbs were over $10 back then. I thought I would learn something about electronics but not really, the failure modes are always the same: about 50% of the time, an LED burns out. 25% of the time, it’s the smoothing inductor gone open circuit. 10% of the time, a bad contact somewhere (usually solder joints on linearly-regulated ones). 5 % work out of the box for some reason. I remain adamant about not paying for LEDs even though dumpster diving is objectively not worth the trouble anymore.

It’s the circuitry that burns out, and many of these filament-style LED lights literally only have a resistor as their main component.

Not true. I’ve been dumpster-diving for LED bulbs for 5 years and in the majority of cases, it’s one LED in a series chain that burns out (fails open circuit). As for the circuitry, the most common failure point is the inductor between the capacitors smoothing out the rectified mains voltage.

Mains filament bulbs with nothing but a resistor exist but they flicker between 0 and 100% at 100 or 120 Hz, which is not very pleasant. Good filament ones have circuitry very similar to the plastic ones. The reason filament bulbs last longer is better heat dissipation from the LEDs, and the circuitry does not get too hot either.

No, shorting a dead LED in a series chain of 10-20 will NOT burn your house down, it’s barely a difference to the driving circuit. Unless you’re buying knockoffs, there is a fuse in the base that will blow at like 0.5 A, no matter what you do to the circuitry. However, the other chips will likely not last much longer than the first dead one (unless you dooby the bulb, see below), so it’s not worth doing, and a poorly reattached plastic globe can come off and expose mains voltage. If all chips are OK, you can cut it open to check the inductor between smoothing capacitors and replace it if it has failed open circuit, or short it if you accept a little extra flicker and/or electrical noise.

I’ve seen power supply boards of LED bulbs that literally burned themselves down to the crisp (never in ones that I modded) but the housing contained the fire thanks to its heat-dissipating design.

In many bulbs, you can adjust the value of a current-sensing resistor (usually one or two in parallel, about 2-30 Ω) to make your own “Dooby” lamp with lower power and way longer life. Of course, you need to know something about electronics.

What can burn your house down is still using incandescent and halogen bulbs. You may lay a piece of paper on top of a lamp and it can fall in when moved by the hot air, touching the bulb…

They are probably very low-power and don’t get hot, which would kill them faster.

I have been dumpster-diving for LED bulbs for 5 years. None of them had 200 chips, they usually have about 5-30 packages with 1-6 diodes each for a total of around 30-60 so that they total some 90-180 V in series (I live in a 230V mains region, and the 330V rectified mains can be efficiently transformed to that voltage by an SMPS). Because they are in series, if one in the series chain fails open circuit (the most common way), the entire chain goes out. Yes, fixtures (not bulbs) with 100+ LED chips exist and if they are designed to operate at a low voltage with all chips in parallel, the failure of one will not affect the others.

Shouldn’t the FCC have a say in this?

Call them Li-Ion batteries to prevent confusion with lithium batteries such as CR-2032, which probably have been used in pagers.

Overloaded Li-Ion batteries don’t reliably explode. I would have expected them to place the explosive inside an oversized battery pouch along with a heating element in series with the battery. A microcontroller on the board could go short-circuit upon receiving a certain message, making a large current flow through the heating element and triggering the explosive.

Well, I’m guessing they concealed them in an extra-large Li-Ion battery and wired a heating element in series inside it, so that shorting the terminals by the circuitry triggered the explosive. Pagers use so little power that the lower capacity would be hard to notice and the heating element’s voltage drop would be negligible. I assume the pagers’ command & control equipment had backdoors, too.
