In case anyone is wondering how to produce documents with complex structure, multiple pages and professional quality using free software, the answer is of course: with LaTeX. Consider the alternatives: Office (Libre, Open, the KDE stuff) are a nuisance when it comes to properly customized sectioning, and for larger documents or 100% precise positioning they […]

PHP HTTPS Streams: Explicitly Using A CA For Verification
20. Juli 2015 in Programmierung, Technik.
When I tried setting my Owncloud Calendar’s ICS export URL (which uses HTTPS) as a calendar import URL in Dolibarr (currently installed are Owncloud 8.0 and Dolibarr from the version 3.6.2-3 Debian package), Dolibarr gave me these errors (taken from the error.log of the webserver, with some additional formatting): PHP Warning: file(): SSL operation failed […]
Rollbare Ablage
27. Juni 2015 in Sonstiges, Technik.
Mit einfachsten Bauteilen aus dem Baumarkt habe ich mir eine Ablage mit Rollen Marke „No Bulls***“ gebaut. Das Möbelstück ist stabil und ziemlich schwer (ich konnte es mit Ach und Krach alleine in den 2. Stock bringen), die Auflage ist relativ solide (es ist halt Grobspanplatte, als Werkzeugablage oder ähnlich ist sie gut zu gebrauchen), […]
Banana Pi Case Remod
25. Februar 2015 in GNU/Linux, Physik, Technik.
I cut a bay for my Clicktronic HDMI-to-DVI adapter into my Banana Pi case. To maintain structural stability of the case, I had to cut about one half of the bay into the lower half of the case and the other into its upper half. To do this, I had to raise the mount level […]
RDP With Copy&Paste From Windows to xrdp on Debian
11. Juli 2015 in Administration, GNU/Linux.
The package of xrdp (Version 6.1.2) that is available in Debian does lack support for Copy&Paste. The „master“ branch of xrdp on github provides this feature but is not packaged for Debian at the moment. To have it available, I built it manually on my Debian server. The procedure took about 1 hour, most of […]
Alles Banane!
7. Februar 2015 in GNU/Linux, Technik.
Aus dem Banana Pi Pro Board und einem „Eurobox“ Universal-Gehäuse Polystyrol (EPS), Conrad Artikel-Nr. 523130 – 62 habe ich eine kleine Appliance für mein Netzwerk konstruiert, die verschiedene Aufgaben übernehmen kann. Als Betriebssystem verwende ich Bananian, welches mir ein Debian Wheezy zur Verfügung stellt. Das System war sehr unkompliziert einzurichten und funktioniert super. Die von […]

32bit UEFI Boot on an Intel Baytrail Tablet
30. Januar 2015 in GNU/Linux.
Acer Switch 10 (SecureBoot disabled) loading the experimental Debian Installer for 32bit UEFI Boot by Steve McIntyre ([ISO]). So far so good, but the Linux itself has only limited driver support, for example, the keyboard of the docking station does not work (a separately attached USB keyboard does work). Wireless network does not work either. […]
