Harder Drive: Hard drives we didn't want or need (2022) [pdf]
- hnbear 2y agoThere's a fantastic associated YouTube video that talks through these too: https://www.youtube.com/watch?v=JcJSW7Rprio https://www.youtube.com/watch?v=JcJSW7Rprio It's a rabbit hole that had be fascinated for quite a while.
- e1gen-v 2y agoTom7 is the goat. Love his videos.
- ivanjermakov 2y agoDupe of https://news.ycombinator.com/item?id=30974165 https://news.ycombinator.com/item?id=30974165 Tom7 content deserves being posted every day though.
- fragmede 2y agoGoogle calendar fs, using Google calendar to store data in events, was inspired by this. Any others?
- quantumish 2y agoit's not directly inspired by tom7, but there's pifs: https://github.com/philipl/pifs https://github.com/philipl/pifs
- baliex 2y agoFigure 1 is somehow beautiful in it's chaotic dis/organised structure, a representation of the whole internet, something which us humans now so heavily rely on ipv6 yadda yadda yadda
- MostlyStable 2y agoI think this is a candidate for best two sentence combo ever written: So we have 1 million chainsaws per second, for 335.36 hours, which is 1.215 × 10^12, a configuration known as tera-wield. This requires expert juggling skills.
- trey-jones 2y agoThe straightfaced and unhinged nature of the chainsaw section reminds me of Hitchhiker's Guide to the Galaxy, and probably some Kurt Vonnegut stuff. I love this style of writing.
- nextaccountic 2y agoI would nominate this one > Tetris is an inventory-management survival-horror game with 19 principal characters, each with its own story arc
- lupire 2y agoNot a 2 sentence combo. Also, for the confused, there are 19 characters if you consider non-trivial rotation to be switching between different characters.
- jdietrich 2y agoFor those who might not be aware, early computer memory relied on essentially the same principle: https://en.wikipedia.org/wiki/Delay-line_memory https://en.wikipedia.org/wiki/Delay-line_memory
- IIAOPSW 2y agoI have a crazy idea. The round trip travel time of light to the moon and back is about 3 seconds, and we did leave a mirror up there. At modern modulation rates and with multiple frequencies of light in use at the same time (aka different color lasers), a lot of data can fit into that 3 second window. A memory made of the vacuum of space. The lightest hard drive ever.
- Animats 2y agoSure. You can also do radio moonbounce, which radio hams routinely do.[1] About 2.5 secs of lag. It takes a sizable antenna. You could probably use that as a delay line. Noisy, so error correction will be necessary. Laser moonbounce is harder to do than radio.[2] Early systems used so much laser power that they had to be equipped with radars to turn the system off if aircraft were in the area. Later systems with safer lasers could detect single photons with a 40cm telescope and transmit a 2KHz signal.
