WeiterlesenUsing nuitka compiler for python3 on Alpine Linux ARMHF (musl)
Motivation pidoctor is written in Python (as there was no easy way to get Crystal to work on ARMHF / musl). This means a dependency on Python – which adds overhead. I suspect that this overhead is the reason that pidoctor will not run on 256 MB Raspberry Pi’s – because the RAM is exhausted…
WeiterlesenDebugging the Alpine boot process
As discussed in my previous post, Alpine Linux goes through several stages when it boots. Just after mounting the boot media, and scanning it for apkovl’s (with nlplug-findfs), there is an option for you to get a console, by setting $SINGLEMODE to yes. Setting SINGLEMODE to yes is easy, you simply add the word “single”…

WeiterlesenInterview with Simon Long of Raspberry Pi about the Raspberry Pi Desktop, UI design, and much more!
Important background information: this interview was done in early July 2018, so some applications to which Simon refers might already be released, etc. Max: This is the interview with Simon Long of the Raspberry Pi Foundation who is mainly responsible for Raspbian the desktop OS. Simon: That’s right. Max: Many applications like VeraCrypt release binaries…
WeiterlesenCrystal & Alpine on the Raspberry Pi
Bringing together two interesting technologies: Alpine Linux – a small-size and security oriented Linux distribution Crystal – a compiled language with a nice syntax (similar to Ruby) on the Raspberry Pi (armhf / ARMv6, which would also support the Pi Zero W) is not possible currently, as of 21.12.2018. There is no (at least no…
