  • Would be interesting to see the Arduino IDE generating “raw iron” code for this quadcore processor. I learned to like the Arduino IDE for the RP2040 with it’s rather easy ability to run code on both cores. Having a board and environment to run raw iron code on four A53 cores would be interesting…

    On the other end, why buying Arduino at all? Why not just providing a qualcomm based board and a matching Arduino BSP? If they want to promote their board and processor, just support it properly on the Arduino infrastructure.







  • First of all, like all skills, the more you do, the better you get.

    One approach not listed would be to read books on algorithms and try to implement them.

    Another would be to read good source code. The “good” part is the difficult one here, though.

    Have a look at “The TeX Book” and/or “The MetaFont Book” - Both books are well annotated “sources” for two working and long-term assumed bug-free programs. You can learn a lot from those, not only about actually writing a program, but you can get a lot meta-knowledge off this project.

    Or look at the sources for the glibc/glibc++.




  • Wow. this is one of the biggest instances of IT incompetence that I’ve heard of in recent years. Hosting a server farm without remote backups? Sound like the London Magnetic Tape Incident.

    The LMTI: One employee was sent to the other end of London with the magnetic backup tapes every day. He got money to take a taxi, but saved it and took the tube. His favourite seat was right above one of the motors, where he sat the bag with the tapes on the floor for the journey. The tapes were just stored at the destination, and not checked in any way. Guess what they learned the first time they had to rely on those tapes?
