I have been using uBlock Origin and uMatrix together for so long, that I don't remember when they became permanent must have.. uBlock origin sanitizes the site, while uMatrix prevents any surprises since I last visited a site. The more garbage the site is, the more broken it is on my setup.
The in-rush of endorphins when the modded LCD thing actually worked probably knocked you out?
A bit of a side story: I disassemble probably 1–5 panels in a week. (For recycling, it takes about 20-45min per panel.) The flat cables alone are so flimsy, I would say just assembling a display again from known, matched and functional parts would take days. I would triple or quadruple that to assemble a display from random parts. Considering this, that modded panel is quite amazing to me.
In standalone panels, the PSU has a chance of killing you: the main capacitors can hold multiple joules worth of nope, charged to about 400v. So, if the main caps are not allowed to discharge (if they discharge at all that is), there is a possibility of death when disassembling a panel with an integrated PSU. Waiting "5min" is bad; a PSU needs to be unplugged for a day or two at least before the charge drains out.
I put too way too much effort in this reply... Yes.. it's nerve racking, especially if you are resorting to BIOS flashback to boot the CPU on an older (new) board.
Can't get visuals (except maybe leds/indicators on the motherboard itself) when your CPU is incapable of accessing the ram or the devices yet. All external devices normally communicate through the RAM. (And by external, I mean not on the CPU package)
Yet, the CPU has to solve out this chicken-and-egg problem of how to progress from the cold-boot without knowing what external RAM is installed. There are plethora of timing/clock-cycle/voltage settings for one stick of ram, which are tested on POST. Establishing sane DDR5/4 parameters is non-trivial. (I think it is order of +20!, twenty factorial: 2432902008176640000, if there were no starting point of XMP, JEDEC etc.)
I use hand tuned settings for DDR4, and on cold boot, the BIOS adjust the settings which I didn't forbid it to do. Unless I unplug the PSU from the wall, the BIOS won't retrain the memory again. I suspect my settings still aren't 100% stable. (over period of years) Non-cold-boot assumes the ram works 100% same on each power up. If some OC setting drifts past a threshold once the system is heat soaked or receives more EMI interference, this could provoke a crash/BSOD etc. in absurd theory having a busy wifi router next the ram could cause the bios to select more robust/conservative settings to counter the EMI interference. Would be fun to know, if this would be true.
(and please, absolutely don't run above as root. Just don't.)
I carefully answered to retain any root owned files and my backups, despite knowing the backdoor wasn't included in the culprit package. This system has now "un-trusted" status, meaning I'll clean re-install the OS, once the full analysis of the backdoor payload is available.
Edit: I also booted the "untrusted" system without physical access to the web, no gui, and installed the fixed package transferred to it locally. (that system is also going to be dd if=/dev/zero'd)
I would highly recommend Curve25519, etc., just because such keys are faster and less common than RSA public-private keys in today's world. RSA 2048-bit keys are considered weak today, while the Curve25519 256-bit keys remain stronger. Also, the ChaCha20-Poly1305 cipher has an interesting backstory and doesn't necessarily need hardware acceleration (which, in theory, could be borked by the HW-vendor) to obtain good performance.
Unfortunately, some SSH front-ends don't play nice with Curve25519 public-private keys yet... (I'm pointing at the putty SSH client, but that may have improved from the last time I had to use it)
The first kernel I built was not entirely happy with the .config I had made for it.
Only thing it could do was BEEP-ing in panic for any key presses. [insert noot noot meme]
This had me chuckling more than I would have thought. It's a obvious reference, and the choice of meme template is a nice twist where s/he is specifically not ignoring the auroraborealis occurring.
It's that time again for TTC until the lights fade away.
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.
I watched YT channel that had rescue toucans and they belong to the wild. Every 5mins the owner reminds (and I believed he was/is a good owner) of this fact.
Funniest thing was the velociraptor mode and pure chaos.
Saddest thing was seeing them die to health complications, despite the good care.
