a fun tangent, on topic as far as visualizing data is concerned.

One card = One line of code, 80 characters.
Oh I see. Although I'm not sure what is that used for unless it's to save cryptocurrency seeds or something like that!

I'm not even sure I understood what you just told me about chatGPT estimating the number of punch cards it would take!

Re: [Hardware] Possible partition corruption in pen drive

In the meantime I was able to learn a bit more about the ISO-9660 file signatures. PDV, SDV and VDST and how to look for them by searching the 1st byte of the specific memory addresses stated by the ISO-9660 standard and I coul find them in a known good ISO file. Of course with the help of chatGPT t...

Ok, I think I'mnot going to dive on this because I would have to ask too many questions and most likelly the thread would eventually die without me being able to finish whatever I woul start!

Re: [Hardware] Possible partition corruption in pen drive

@CwF, was it this thread? https://forums.debian.net/viewtopic.php?t=148065 I tried to open the SD card (I named the thread as pen drive but I am wrong. It's an micro SD card, but I guess it doesn't matter) with an hex editor. I got this: 00000000 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |.......

Ok, you're awsome man. It's working as intended, I guess.

By the way, are you used to work with GMP library or you just saw it for the first time as me?
