Last year, while idle at work (I was working in a telecommunications service provider provider, don't know how to say it in english) I've tried "play" blindly with some unused DSL modems that were left in stock, my Idea was to recycle them and maybe install some wrt solution in them (and I'm a little of a hoarder, I find beauty in trash, specially if trash still works). I was able to communicate with them via ttl to usb adapter using putty (yes, work computer had windows in it, I'm pretty new to linux) and that's it, as pandemics recoiled, idle time was scarcer and scarcer so I left my rudimentary experimentation. Anyway, it was glorious when I saw a linux shell coming out of the modem. Later, this 2021, I went from 2 subjects for quarter to 4 or 5, soI left that full time job and after living upside down doing some freelance translation jobs for around 4 months, 1 I took a 4 hour tech support internship in order to get out of my place and see real people and go to sleep and wake up more or less with the rest of my human suroundings. This mail is getting long and I'm getting tired and not reaching the point where I say what I want to say (maybe I'm not sure of what to say). In the second quarter of 2021 I found out that one of the subjects is about embedded linux. They point it to a raspberry pi that doesn't exist anymore as during pandemic lockdown someone entered the faculty and took the prototypes. Anyway I learned a lot more and am not as blind as I was in 2020. We use qemu, uboot, configure and cross compile a linux kernel, then use busybox filesystem and there's as far as I got Have any of you done some experimentation of this sort? Do any of you want to? Thanks and sorry for the messy and long and self-referencial email. tere
