Unsere Mission ist es, jeder Schülerin und jedem Schüler in Deutschland ab der 3. Klasse einen spielerischen Zugang zur digitalen Welt mit Hilfe der Calliope mini zu ermöglichen.

Our mission is to give pupils from year 3 onwards a playful approach to the digital world.

With Calliope mini you have countless creative options right at your fingertip. You want to build a robot or transmit messages? With just a few clicks you can create a program for the microprocessor and make things move.

Besides 25 red plus one RGB LED and two programmable buttons the board contains a combined position sensor with motion sensor and compass as well as a bluetooth module that allows the Calliope mini to communicate with other devices. The board can't only be programmed with your computer: you can use an app to transfer apps you created yourself to your mini computer.

Purism and KDE

This one with Plasma Mobile would be really nice. The only combination so far I would replace SailfishOS and Jolla with.

Librem 5 – A Security and Privacy Focused Phone
Librem 5, the phone that focuses on security by design and privacy protection by default. Running Free/Libre and Open Source software and a GNU+Linux Operating System designed to create an open development utopia, rather than the walled gardens from all other phone providers.

A fully standards-based freedom-oriented system, based on Debian and many other upstream projects, has never been done before–we will be the first to seriously attempt this.

Purism and KDE to Work Together on World’s First Truly Free Smartphone
Berlin/San Francisco, September 14, 2017 — Purism and KDE are partnering to help KDE adapt Plasma Mobile to Purism’s Librem 5 smartphone.

KDE develops Plasma Mobile, a free, open and full-featured graphical environment for mobile devices. Plasma Mobile has been tested on several off-the-shelf devices. However, most smartphones include hardware that requires proprietary software to work. This clashes with KDE’s principles of freedom and openness. It also makes building difficult, since many details of the hardware are kept secret, preventing complete access to all the components.

building DC power grid

#^The Alternative Power Network – Providing a DC grid for hacker events.

Hello and welcome to our information site. We are designing and building an alternative power network for the upcoming big Dutch hacker event SHA2017.

The idea of building a DC power grid to experiment with came to us at CCCamp 2015. We asked around and many people of the community would like to have an opportunity to share their surplus of solar / wind or other eco-friendly power during hacker events. Some people like the idea they can use “green” power on events, even if they have to modify some systems for it or adapt to using less power. Others are interested to study the dynamics of a DC system or would like to figure out how to send data over a DC grid. We would like to satisfy all of those people by building a transparent DC grid.

KDE Slimbook

#^KDE and Slimbook Release a Laptop for KDE Fans
Today KDE is proud to announce the immediate availability of the KDE Slimbook, a KDE-branded laptop that comes pre-installed with Plasma and KDE Applications (running on Linux) and is assured to work with our software as smoothly as possible.
The KDE Slimbook allows KDE to offer our users a laptop which has been tested directly by KDE developers, on the exact same hardware and software configuration that the users get, and where any potential hardware-related issues have already been ironed out before a new version of our software is shipped to them. This gives our users the best possible way to experience our software, as well as increasing our reach: The easier it is to get our software into users' hands, the more it will be used.
Furthermore, the KDE Slimbook, together with KDE neon, offers us a unique opportunity to isolate and fix issues that users have with our software. When something in Plasma, a KDE Application or some software using a KDE Framework does not work as intended for a user, there are at least three layers that can cause the problem:
  The KDE software itself
  The operating system
  The hardware or its drivers
Of course KDE always tries to reduce bugs in our software as much as possible. Problems can occur in any of the aforementioned layers, however, and often times it is difficult for us to pin-point exactly where things are going wrong. Last year, KDE neon joined the KDE community with the promise to give us control over the operating system layer. This does not mean we won't make our software available on other distributions or operating systems, of course, but it allows us to eliminate that layer as a possible source of a problem.
This left us still with one layer we had zero control over, though: The hardware layer.
Fast-forward to late last year, when the Spanish laptop retailer Slimbook approached KDE with the idea to offer KDE-branded laptops that come pre-installed with Plasma and KDE Applications. We were excited about the idea, and put our designers and developers to the task of creating a branding for such a device and making sure that KDE neon runs without any hardware-related issues on it.
For now, the KDE Slimbook will always come pre-installed with KDE neon, but we are open to offering other distributions that come pre-installed with Plasma for customers to choose from.
The KDE Slimbook is for people who love KDE software, regardless of whether or not they are active contributors to KDE.

Openmoko retrospective

 Tue, 29 Nov 2016 17:35:14 +0100 
#^Ten years anniversary of Openmoko
In 2006 I first visited Taiwan. The reason back then was Sean Moss-Pultz contacting me about a new Linux and Free Software based Phone that he wanted to do at FIC in Taiwan. This later became the Neo1973 and the Openmoko project and finally became part of both Free Software as well as smartphone history.
Ten years later, it might be worth to share a bit of a retrospective.

#^MOnSter 6502

A new dis-integrated circuit project to make a complete, working transistor-scale replica of the classic MOS 6502 microprocessor.

How big is the MOnSter 6502 compared to the original 6502 die?
The original device was 153 × 168 mils (3.9 × 4.3 mm) or an area of 16.6 square mm. Given that ours is 12 × 15 inches, that makes it about 7000 times actual size.
How big would a 68000 microprocessor be at the scale of the MOnSter 6502?
Also about 19 square feet (1.7 square meters).
How big would a modern CPU be at this scale?
The Apple A8X, found in the iPad Air 2, contains about 3 billion transistors. (This is comparable to the number of transistors in modern desktop computer CPUs as well.) At the scale of the MOnSter 6502, that would take about 885,000 square feet (82000 square meters) — an area about 940 ft (286 m) square.

Over one week and I got two fully assembled mainboards, two completely new power supplies and I only have to plug in foolproof connectors according to the instructions, but I still have no working computer. o_O :-!
CPU fan spins up, power LED is on, hdd spins up, no video output, no blip. Have triple checked and replaced every piece to connect peripherals to the board and they are working. There is also no error blips when no RAM is installed at all. The mainboard instructions say I need 500W, I got a 550W power supply.
Can two fully assembled boards be damaged out of factory or is it not really foolproof? This is really depressing not finding out why it is not working.

Only made to break

 Wed, 19 Nov 2014 23:43:17 +0100 
I fucking hate modern hardware!!! It only breaks and you can do nothing to fix it.

Since two days I have no sound on my #Jolla phone anymore. No music, no alarm, but I can still talk on the phone at least. Had this problem before and a reboot solved it, but not anymore. :-(
Monday I bought a new mainboard for my computer, that broke Saturday. Just to realise I need also a new power supply because the old one has just 2x2 power plug, but I need 2x4 for the new CPU. So the next day I got a power supply finally. After everything was assembled only the CPU fan spins, CD and HDD rotate, but no screen, no keyboard LED, even no error speaker sounds. :-! Today the shop was already closed when I returned from office. Let's see when I will have a working computer again.
