Btw. I'm having a party tonight like NOW.

Me 2023: It will take only a few weeks, right? RIGHT?

A year later: I re-wrote the entire damm plugin. Have a good day.

"When you do things right, people won't notice and it's like you have done nothing at all."

Futurama or something something quote likely not word-to-word correct.

Sugar is half bad, half good: the glucose part causes no harm and whole body can use it. The fructose part on otherhand is bad and has to/can only be processed by the liver first.

This was truly a wtf moment of the month.

Last time I spent time watching him was when he freaking fixed the kexec syscall for IBM PowerPCs. for free

A greentext moment:

Decide to listen sweet sweet psytrance.

Playlist only available on Spotify.

Don't like non-free software. (a fucking 1TB disk full of free)

Try make the account anyway.

Somebody else has registered your email.

Request to recover password.

The request arrived at my mail box. Freaking out. No memory of why, when or how.

Listening sweet sweet psytrance.

(Still freaking out.)

I once helped a person with their computer. They complained the they cant save the their photos. Well, their onedrive was filled to brim with crap, while the local 1Tb disk was empty because they had zero idea how storage and folders work. I had to explain her there is literally 1000x more fast disk space available, so please dont save into onedrive.

The backdoor has existed for a month at least. Yikes.

Maybe not in a flashlight, but the scientific industry would be very pleased with them. Sterilize water and all surfaces in a second? Flash with 200nm light.

This was an yet another glorious episode from veritasium.

I hope we get well past UVC LEDs. (i.e., shorter wavelengths) UV LEDs are already available. Unfortunately, this progress will stop before X-ray light. With +1 KeV energy, you pretty much must blast off the electrons from the atoms to emit X-rays, which an x-ray tube already does. Or by peeling off a piece of scotch tape.

Any new battery technology news needs to be taken with a grain of salt. They are highly likely over-hyped and the actually realized products will have more problems than the current established tech initially.

Quantum computing is going to make it possible to solve problems that normal computers simply cannot do.

Most of these are optimizing problems like "compute the best solution to traveling salesman" or "find a molecule that binds to this receptor".

On normal computers solving such problems "perfectly" takes^exponential^ amount of computing time vs. the size of the problem.

Quantum computers are going to chop down that exponential thing a little, so we can see the results before the sun burns out. The reason QCs are theoretically able to do this is that each added qubit improves the machines performance exponentially.

However, the qubit state is so fragile that we need hundreds of them to make a single "stable" logical qubit that can do operations repeatedly. What the quantum computer uses as qubit (photons, super-conducting wire) is irrelevant as long as the system can do useful work.

Because of the fragility, the results are gathered using thousands of runs on the quantum machine and measured statistically.

We are not quite there yet to solve any useful sized problems.

Based on the article the satellites are not staying 100% on their intended spectrum spec and are bleeding some unintended interfere noise. I hope the starlink cloud doesn't interfere so much that it excludes possibility of some research. On earth, if you transmit even slightly out-of-spec radio signals, the government agencies will get mad and really really fast.

ELI5: Low earth orbit is becoming over crowed "FM radio station", with regulation lacking who can broadcast and at what frequency.
