      Kommentare deaktiviert für Purism Librem 5 – It’s Coming!

Some may already be aware of it, since September 2016 I am member of the Purism Advisory Board and consulting Purism in matters of mobile devices. As development continues I have been asked beginning of 2017 if I could imagine to lead a mobile device development. After some further discussion about possibilities I started to lead a mobile device development… Read more »

Bundestagswahl 2017 – Erschreckend starker Nationalkonservativismus

      Kommentare deaktiviert für Bundestagswahl 2017 – Erschreckend starker Nationalkonservativismus

Diese Bundestagswahl ist erschreckend! Mit der AfD als drittstärkste Partei zieht nach über 70 Jahren wieder eine national konservative Partei in den Bundestag ein. Dumpfer Nationalismus, Heimatstümelei und stures Festhalten am Gestern, sind damit wieder im wichtigsten Deutschen Politikbetrieb vertreten. Es ist erschreckend, mit welchen inhaltsleeren Parolen soviele Menschen ihre demokratisch Stimme dieser Partei gegeben haben. Nach über 70 Jahren… Read more »

Intel ME – When the sh*t hits the fan :)

      Kommentare deaktiviert für Intel ME – When the sh*t hits the fan :)

You know, there is a lot of cruel stuff going on these days. Freedom is cut away in many places which in many cases is done by taking away power and control. Having full control over something means to have power and to have the freedom to use this power or not. The Intel ME is a technological implementation of… Read more »

One of the most common issues in embedded device engineering is how to create a development toolchain and following this how to create a root filesystem to run on the target. These are sometimes also called development and runtime systems. There are several solutions to do this but let us look at some of the challenges first. Challenges Reproducibility There… Read more »

Purism Librem 15 – First impressions

      Kommentare deaktiviert für Purism Librem 15 – First impressions

Yesterday I finally received a Purism Librem 15 laptop for review. A few months before I also got a Librem 13 v1 which was already pretty nice but showed some details that I did not fully like for a device at that price point. The new Librem 15 v2 in contrast is a really nice device. First of all all,… Read more »

For a project I am currently evaluating embedded CPUs, so called system on chip (SOC), mostly ARM architecture. One major requirement of the project is to use free and open source software only, without any binary firmware blobs. Introduction You may have heard about the big issues found lately about e.g. the Intel Management Engine (ME) which is part of… Read more »

Debian unstable ARMHF rootfs

      1 Kommentar zu Debian unstable ARMHF rootfs

I have created a current Debian unstable (post „Stretch“ 9) rootfs archive for ARMHF (ARM hard float) devices, download here: http://www.dpin.de/downloads/debian-armhf-unstable-rootfs.tar.bz2 this is about 90MB. It can be put on a SD card to boot ARM HF devices and to install more stuff from there. I use this on an i.MX6 dual core board so there is an extra entry… Read more »

Pinebook, after first week

      Kommentare deaktiviert für Pinebook, after first week

Well, I was aware that the Pinebook is not meant as a day to day laptop replacement. It is rather an experiment, targeted at enthusiasts and developers. Heck, I am both 🙂 So I like it! Despite software glitches and some (minor) hardware issues. But first start with what we get. The Pinebook comes with a 11.6″ or 14″ screen,… Read more »

Wenn Trans* Menschen telefonieren

      Keine Kommentare zu Wenn Trans* Menschen telefonieren

Das passiert, wenn trans* weibliche Menschen wie ich mit uninformierten Call-Centern telefonieren. Anrede und Schreibweise des Vornamens sind „bemerkenswert“. Ich hatte der Damen am Telefon ausdrücklich alles buchstabiert und erklärt. Doch das passte offenbar nicht in ihr Wahrnehmungsschema – hach ja… anstrengend, nervig und schon fast ärgerlich.
