@bougiekitty Its weird how if you fire all of the people who understand how the code works, you break things when you try to make changes. Very confusing.

@osinttechnical thanks for sharing here. You're one of the only accounts I still login to Twitter to read, appreciate being free entirely of the bird site today.

Purely idle musings. Systems I wish people would rewrite in #rust: - ntpd - gpsd - postgrestell me why I'm wrong or what I'm missing. (rationale: ntpd is critical software with a history of security vulnerabilities and a requirement for tight timing. extensibility would be a very nice thing. gpsd for basically the same reasons + ESR. postgres because I like it.)

CMU has decided that everyone has to install Crowdstrike on their computers.As it turns out, there's no crowdstrike module for FreeBSD.Guess it's time to move the rest of my machines to FreeBSD. 😜 I'm glad I'm not a security admin person at a university because herding people like me must be a nightmare. But keep your hands off my computers, please. I don't trust you.

Guess I need to remember that November is ☣️biohazard month for parents☣️ again - and it's not even covid. 5yo gave me his sinus infection, which had me on the floor for 10 days (and while i'm a lot better, i was winded doing a single boulder problem today). Now prof. dr. spouse and 11yo both have it and they're vegetables. And three of my friends have covid.Meanwhile 5yo is bored out of his seat with the sick family. Anyone want a 5yo for a while? Lots of energy, likes to cook.

@cody @arstechnica It's water _with bacteria in it_ that's introduced because there's no process control that ensures that it's actually sterile.Don't put bacteria in your eyes. If you want to put water in your eyes, go get some saline that's manufactured under controlled conditions to ensure sterility.

@cody @arstechnica The same legal quirks that let them sell their stuff as if it was effective let them manufacture it without any oversight to make sure that they're actually making it sterile.

@futurebird yet another case of people forgetting how bad it was before the widespread adoption of a public health intervention. Sigh.

@futurebird The colleague whose enthusiasm for e-bikes pushed me over the edge to getting one broke his collarbone when his cheap drive system engaged at the wrong time. His experience convinced me it was worth getting a good Bosch mid-drive with really high quality breaks, and I stuck with a 250 w motor despite occasionally carrying two kids on it. That gets a little sweaty uphill, but no regrets. (Caveat: I MTB'd and races road for a while, so my ideas of speeds are probably not normal)

@futurebird So, you see, back in the previous millennium, the Americans and the British were so confused by the units that they used that they had to invent devices called computers to help them figure them out, and that's why we have ceiling cat.

As part of repairing a disk failure, I'm replacing a single working 18TB disk with a new 22TB disk, and then re-using the 18TB disk to replace a dead 18TB disk in the big 11-disk RAIDZ-2 array.Every time I do this after another year or three has passed, I appreciate Bianca and Garth's message about the danger of HD capacity increasing quadratically vs transfer speed increasing linearly...1+ day just to copy the disk. (!)(Ref: https://www.cs.cmu.edu/~bianca/fast07.pdf"Disk Failures In The Real World")

By way of explanation: Disks are effectively 2D -- it's a spinning plate. So when you do the magic shrinky thing, you shrink in both the X and Y dimensions. If you shrink one of those dimensions by half, you overall fit 4x more data on.But disks are read linearly - the read head reads one track at a time. So that same 1/2 shrink doubles the read speed but 4x's the storage, so your time to copy the entire disk effectively doubles every time you get 4x the capacity.#storage #disk #raid

This is a little problematic because it means your window during which you might experience _another_ failure grows. Decades ago, you might have had a 40 minute "double failure will kill you" window; today it's a day. So we've generally had to move to more redundant systems, like the aforementioned RAIDZ-2, which can tolerate two simultaneous failures without data loss.

@emilygorcenski As a reformed biologist: It's interesting to me how often people (particularly engineering people, which I am also) want to find more structure & sensibility than is really justified in the ungodly mess that is the result of evolution. Yes, there's structure and repetition, but there's also a lot of "well, that's just how it is because it boosted relative fitness."We're pretty good at seeing patterns even when they don't exist. :)

It's really bizarre that this election is anything but a landslide.I'm one corner, a former prosecutor, senator, and current vice president, who is if anything a little more centrist than I would prefer and will likely be a very competent establishment politician.In the other, a convicted felon and sexual abuser who tried to overthrow American democracy once alreadyAnd third <listens to headset> an, um, anti-science wacko who says a worm ate his brain and who hid evidence of a bear killing

lol. gotta love crypto. I realized I had about $50 of bitcoin hanging out somewhere, so I transferred it to coinbase to sell and turn into usd.I used an old address from coinbase's "gdax" exchange, which they merged into their new coinbase advanced.The money disappeared. Coinbase happily told me "sorry, that product is deprecated, the funds are lost on the blockchain."These are not serious people.
