USB Floppy Drive
!retrocomputing
Came across an old USB floppy drive. I plugged it into my machine and it shows up, but I can't tell it it's actually working or not. When plugged in, it sounds like it's continuously reading, so I kind of want to test it. Can you even buy floppy disks any more?
That said, if I don't have any disks, I guess the question of whether or not it works is moot anyways.
I occasionally find 3.5" floppy disks at the local thrift stores. There are usually new old stock disks on ebay too.
The USB floppy drives usually only support IBM formatted disks and are useless for data recovery. For any other formats, a Greaseweazle will come in very handy.

we're also still very fond of text files.
it used to be quite common for people to write up, say, videogame walkthroughs, or gender transition how-tos, or any sort of information somebody had personally put together, in a single long text file. a quarter of a meg was on the larger end of what you'd see, size-wise (when it's just text, that is a LOT), but not uncommon.

I recommend people to investigate used enterprise storage.
If it passes badblocks & SMART checking (don't rely on that too much, manufacturers do silly things), it is likely to work just fine, and depending on one's location it is possible to acquire triple-redundant 10TB for less than buying a single 10TB drive new would cost.
Unfortunately, you're pretty much out of luck.
The used ones are not a good idea (despite looking cheaper), they're often messed up in a number of ways. ๐ฟ

files) partitions, and use good old tar
right to the raw partition block device.
If you ever get to the point of thinking about multi-drive enclosures/cradles though, don't go for USB.
At that point, anything less than SAS (an expander card & breakout cables in an old computer case can do the job quite well) will inevitably prove frustrating through all sorts of annoying issues.
Conventional Hardware & Software RAID has also been exclusively for stuff where you don't care about integrity ever since 520B sectors have stopped being used. (Those 8 additional bytes were for integrity-checking features.)
Now, such features are implemented instead in modern filesystems since awareness of the data structuring is necessary for sane & reliable recovery (conventional RAID assumes that the drive firmware will both detect *and* notify of errors, which is incredibly optimistic in a setting where general pessimism is the sane attitude).
1. TIL about 520/528B drives. According to one forum post they might even go back to the 70s ("someone on the Internet said it, it must be true!")
2. Integrity checking features? You mean extra space for higher-level checks besides the (40 or so) extra error correction bits used to protect the 512 bytes of data?
I.e. the wrong data could be correctly written to disk. ECC won't catch that during a read, but the extra 8 bytes could.
The amount of ECC the drive
adds is unspecified, but even before drives switched to 4K sectors with "512 emulation", the size of ECC was typically much higher than in early 5ยผ ESDI/SCSI/ATA drives.
1/
The extra "tag bytes" were mostly intended for file systems that wanted additional metadata associated with the sector, as done e.g. on the Xerox Alto, Apple Lisa and early Macintosh, and IBM AS/400. This could include an identifier for the containing file and offset, but could also be used for filesystem-level error detection.
2/
It is not unknown for drives to erroneously write to the wrong sector, and when the victim sector is read later, the drive will return that _wrong_ content with no error indication. Using the tag in such a way as to detect this kind of error is obviously useful for the filesystem or RAID layer. In the case of RAID redundancy it may be correctable, but otherwise it's still desirable to report an error rather than blindly proceed with invalid data.

I've been working through some #soroban exercises try to actually become reasonably proficient in its use. Interestingly enough, I'm doing much better with multiplicaiton/divison than I am with the addition/subtraction questions, but that's because the latter involve summing a column of values rather than just multiplying two numbers. There are more places to screw up.
Still, these questions seem designed to deliberately screw me up with things like multiple carries, changing the value on a rod just to immediately revert that change, etc.
Still, it's probably that way for a reason.
I don't want this place to be a "Twitter replacement". I came here (in the pre-Musk era) because I wanted something better* than Twitter. The fedi certainly has its shortcomings, and we need to work to improve it (especially regarding the treatment of marginalized people), but Twitter should not be the yardstick we measure ourselves by.
* "Better" is of course subjective.

Dear everyone on the Fediverse who posts anything political...
If you're not going to put your post behind a "political" content warning, then please at the very least use FULL NAMES instead of nick names like "Orange man" or "Kama" or "Vice Daddy" or whatever.
It makes it hard for those who are trying to filter out political content from their feed.
Thanks.

I am neither for nor against AI, mostly because it's essentially a meaningless word. What does bother me is the number of people who are shoehorning it into their products because investors lose their minds and shovel boatloads of money at them.
It's not that I have a problem with fools taking other fools' money; I'm just really sick of them trying to sell me their magic beans.

I fear that people have become desensitized to seeing teachers asking for help with wishlists.
Each year we are inundated with teachers essentially begging for help. I see it & feel it too.
I am one of those teachers who would not be able to run a classroom without the kindness of strangers.
I apologize & thank you in a single message, because I know many are struggling too. A boost is equally appreciated.The students are back & I didnโt lose anyone over the summer!

@EdCates You have zero (read zero) reason to apologise. The folks in charge of implementing a system that leaves teachers in such a predicament should be the ones hanging their heads in shame (I wonโt hold my breath).
You exemplify everything thatโs good in the system despite the system. I hope your students know how lucky they are to have you.

Sometimes I think being a teacher in Norway is hard and unappreciated by the masses. (Hah, I first misspelled masses as "asses", and found it quite fitting)
Then I think of the working conditions of teachers in the US and realize things could be a lot worse..
I really hope the US finds a new way forward soon, a way where teachers don't need to beg strangers for help to get basic equipment to do their jobs, and get decent wages..

No just put me out of my misery. Send me to the farm upstate. Your haptic feedback is a mockery of the elegance of the latching switches and potentiometers I have known.
Robotics is hard. Mechanical engineering is hard. The glass rounded rectangles are magical, yes, and lovely, but they also prisons for the imagination.

my university has converted our office telephones to Microsoft Teams. when i grumbled about this to a favourite sysadmin, this is how they responded ๐ฅ
โMicrosoft has actually brilliantly leveraged the lousy security landscape -- for which they are in no small part responsible -- to capture even larger market-share, as we now need commercial entities to produce the software required to protect us from their failures, and therefore need a more uniform environment to achieve the necessary scale. The uniformity then guarantees an ever greater scale for the inevitable conflagration. Monocultures guarantee one big fire instead of a bunch of small survivable ones. We really have no interest in learning from evolution, in no small part because it would produce fewer billionaires.

So I think that when I took off after Benny when he got loose I got into some poison ivy/oak. I'm normally careful about such things, but I had to be quick to catch him.
I washed my arms immediately after and slathered them with afterbite (which I figured was the most useful thing we had on hand) but there was some itchiness/rash shortly thereafter. Fortunately Benny seems to have been unaffected.
Could've been a lot worse.

Remember, no matter how much neoliberals will try to convince you:
Public services should not be required generate income.
Water, Power, Communications, Healthcare, Education, Public Transport, Mail, Firefighters, Police, Libraries, Swimming Pools, Roads, Generally all infrastructure, Military
None of these things were created with the idea of making big profits with them, they are meant to provide you with a service which is being paid for with your taxes. Privatizing any of them will make them worse, not better.
Though, companies are very good at pretending they are better for a while, by simply deciding to lose money for a few years. The bill always comes due before long, though.

Just for fun, I decided to look into how to use an abacus the other day. I have no practical use for this whatsoever, it was just something I was curious about. Learning this of course made me want to buy an abacus. I know myself well enough to know that while it would probably be an inexpensive purchase, it'd only end up collecting dust on a shelf within a week.
Then I thought about programming a virtual abacus that I could then play around with. I know this to be an absolutely absurd idea, but that absurdity only kinda makes me want to do it even more.
So it's fun to use and all, but it's way too easy for a fumble with the keyboard to mess the whole thing up.
Besides, now I'm looking into soroban-style abacuses (abacii?) They seem more interesting. I'm probably going to break down and actually buy one.
