Tape drives. Remember those big reels of tape on mainframes in the 80s? They don’t look exactly like that anymore, but tape is still used for backups/long term archival because they offer the lowest cost per gigabyte and decent longevity without needing to be powered, as long as you don’t need to access the data all that fast or often.
Those dank memes and cat videos you posted in 2010 are probably on tape in a data centre somewhere
Im obsessed with tape storage, but for audio. Nothing more real than audio on tape! Luckily it’s catching on again. Music is so disposable now, I hope we can keep physical formats alive and keep corporations away from it (digital offers them unlimited control over us).
Can you drop some tape player recs to save me on tape spaghetti?
Oh sorry, I meant more reel tape not really casettes, but I love the otari mx5050, and the teac 2340sx. Good machines and 1/4" tape is still affordable. PM me if you’d like more tape info, I love to share.
Ah okay haha. Ive been buying vinyls lately and there’s a lot of people with casette merch too. I didnt remember tape being that amazing but was willing to give it a shot. I don’t have reel to reel space at my place unfortunately. Thanks for putting it out there though!
Tape itself is cheap, but buying the other equipment for it costs a fortune.
Tape is rad for long term storage
Apparently trains for some people
Guillotines
Handtools in woodworking. There are some people who refuse use a tool without a cord.
Pretty much anything in a machine shop made in the last 80 years or so. So many people turn up their noses at anything that isn’t computer controlled anymore. Yknow what a big old mill can do that a CNC can’t? It can make every single part needed to make a new mill. It’s a self replicating machine with the right know how. People don’t respect that kind of quality anymore.
I don’t think a mill can make the copper windings in the motor and isolate them. Same with the power cable.
You don’t need an electric motor. You just need enough spin. I’ve seen old mills and lathes that run on steam. An electric motor just happens to be very convenient with our current technology.
Can a CNC not do that for just the mechanical parts?
(I know way too much about bootstrapping semiconductor production at small scale, which seems to be viable but highly impractical)
Sure, but it’s not as impressive (imo) when you also need a computer control system, a bunch of circuitry and electronics, and a whole mess of software to make it work in the end. A mill just needs enough spin and it runs exactly as intended.
Oh yeah, I have a copy of the Gingery books and I love it.
I haven’t seen Gingery into how much power you need exactly, or what blend of RPM vs. torque is ideal. What would be your guess, since it sounds like you might know?
Torque is the real limiting factor. You can always gear up or down for whatever you’re working on, but at the end of the day you need enough torque to get the work done. And a proper milling machine needs A LOT of torque.
Can you give me some typical values, maybe? That would be a big help.
There are no “typical values” when you’re running a mill or lathe. You could look up “speeds and feeds”, but that’s really just a table that you plug into an equation to figure out how to set the machine. It all depends on what you’re doing and what you’re doing it with. Drilling a hole with a high speed steel drill bit is going to be a bit different than drilling it with a carbide spade, and all that is going to depend heavily on whether you’re trying to run through titanium or tin. You need to fine tune running “x” bit through “y” material for a “z” sized cut.
Essentially, this is the knowledge that separates skilled labor from manual labor, and machining is (was, RIP cnc button pushers) skilled labor.
At the end of the day for most metal machining you’ll need between 50hp and 100hp to be up to modern standards. If you want to get that through steam or electric motors or whatever that’s up to you
Yes, they make massive CNCs.
Trackballs
You might think of them as this old mouse that you had 20 years ago, but actually the technology is still being used for all kinds of things, including ergonomic mouse
I can actually game with one, and I’ve outright worn out 3. They last longer than traditional mice too.
Darcs VCS
Ota analog signals.
Fax machines. Government and medical offices would grind to a halt without them. That’s just reality.
Came to say this. Fax just refuses to die.
Because it can do something that the alternatives can’t do or because they refuse to use something more modern?
“It can’t be hacked”
Of course, it can, and a lot more easily than a TLS stream, but try convincing them of that. So, more like they refuse to use something more modern.
Everyone even tangentially related to healthcare is terrified of violating HIPAA in a way that leaves evidence that can be traced back to them. So the corps force dumb shit like this, while the employees are perfectly happy to tell all kinds of private health information to anyone who will listen. Especially if it’s funny or gross.
Believe it or not, Canadian health services do this shit too.
Because it works. Every part needed to run those machines, even line of code, every possible cause of failure is well documented and there are layers and layers of redundant protocol to ensure that if something does go wrong downtime is minimal.
The entire purpose of these machines are designed to run for as long as they’re needed. They’re not replaced or upgraded because they were never meant to be. A lot of effort went into this being the case.
That’s basically the answer to the opposite question: what is something that someone thinks isn’t obsolete, but really is?
Even worse, the US military, at least, is still using teletype machines and COBOL.

Printing out tickets as a backup. I do this for concerts and travel because then I don’t have to worry about batteries dying, wifi/roaming not being available, getting logged out and having trouble getting back to the ticket, etc.
I also print out maps when doing wilderness backpacks because even if you download the map you’ll burn through your battery life well before the hike is over but a paper map is just as good. If I really need to confirm my location I can occasionally turn on the app and shut it off. I keep the maps in a gallon ziplock so water isn’t an issue.
Ticketmaster is doing their very best to make paper tickets unusable with refreshing barcodes. Funny thing is that “anti-theft” feature is needed because of their own systemic failures. I do like tickets that are just sent to my email or similar (e.g. as an attachment that I can save to my phone) though, it’s better than wasting paper when I know my phone won’t fail me.
I want to throw a shout out to the site that cloned the old Google reader by making theoldreader.com
Thanks for this, I was so disappointed when Google cancelled Reader.
