Yet another victim of AWS's "macOS machine won't boot due to outdated firmware" problem has appeared... :woozy_aws: The problem has allegedly already existed for years, and it's also already 1.2 years since I documented it. But today it's still broken, and AWS apparently still hasn't acknowledged it in the knowledge base...

AWS's macOS obsolete firmware problem just claimed yet another victim. :woozy_aws:

Q: What do you call an AC voltmeter with free firmware?
A: TrueRMS voltmeter.

How do I know if a mail is spam: Open in mutt, see 100 kilobytes of HTML code, delete.

Coming soon: FTTM (Fiber To The Moon)

#BOFH excuse: PCIe MSI doesn't work because you have a Asus machine.

Q: What do you say when a research team builds a large laser but without publishing any schematic?

A: Proprietary-Electron Laser.

@mkj@social.mkj.earth There's no RF impedance matching problem in lab measurements that can't be solved by a 6 dB pad. If there is, use two of them at both sides.

"if your coax has loss — and what coax doesn’t? — you are probably getting an artificially low reading [of SWR] by measuring at the transmitter."In signal integrity, sometimes it's not a bug, it's a feature. Ethernet PHYs may stop working if you have an extremely short cable as reflection is not naturally attenuated. Optical transceivers too.

"At the beginning of the week, we sealed ten BSD programmers into a computer room with a single distribution of BSD Unix. Upon opening the room after seven days, we found all ten programmers dead, clutching each others' throats, and thirteen new flavors of BSD."

Free Software Express:
All passenger bring a piece of the aeroplane and a box of tools with them to the airport. They gather on the tarmac, arguing constantly about what kind of plane they want to build and how to put it together. Eventually, the passengers split into groups and build several different aircraft, but give them the same names. Some passengers actually reach their destinations. All passengers believe they got there.

@navi@social.vlhl.dev @lanodan@queer.hacktivis.me @chjara@akko.wtf Just like digital oscilloscopes. Analog ones sometimes use delay lines in the signal path, undelayed version for triggering, delayed version is the main signal, so you can trigger everything before the signal arrives. In digital scopes, everything is always on, writing data to a ring buffer. If a trigger arrives, a small window of signal data before and after the event gets saved. Without a trigger, the signal is overwritten after several nanoseconds.

If a polygraph can detect lies for real, it should start beeping the moment you turn it on.

@whitequark@mastodon.social This change was proposed by me many years ago on IRC, but I never bothered to write it down. I was delighted when I first saw the independent rediscovery and realization of the license.

"Q: How do Install nvidia-legacy-300xx-driver on Debian Bookworm? Recently I've tried to follow a video of the 'Linux gaming experience'"That's your first mistake.

USB hub and adapter vendors should be forced to disclose their chipsets, otherwise it's like buying a desktop computer without knowing its CPU.

"Disable XSAVES only on machines which haven't loaded the microcode revision containing the erratum fix. This will come in handy when running archaic OSes as guests. OSes whose brilliant programmers thought that CPUID is overrated and one should not query it but use features directly, ala shoot first, ask questions later... but only if you're alive after the shooting."LMAO :blobcatlul: https://lore.kernel.org/lkml/20240321120548.22687-2-bp@alien8.de/
