Android / Development / Linux
I’ve got a new gadget, a nice and small Android based smartphone, the HTC Wildfire S (WFS). The week before I got it alquez finished porting CyanogenMod 7 to the wfs. I’ve installed it and started to use it. After some time I was curios how to build the system. I’ve asked alquez how to set it up and I built it from source. Then...
chroot for users suck! It is work to maintain them and all in all you have to do a lot of nasty hacks to get it going! In the meantime AppArmor is in the mainline kernel. It is pretty simple to write rules for it and you can easily update it with tools like ‘logprof’. Here is a small howto to trap users in their...
For my git repositories I use cgit as the web frontend. The package I used had a problem displaying the treeview. Looking at /var/log/messages I saw that it segfaults. I’ve already fixed a segfault in cgit some time ago. I wondered how I was able to get gdb attached to it. It took me some time to figure it out so this is the way...
Development / KDE / Linux / Samba
Three years ago Michael Adam created a nice library to easily read the Samba configuration or modify it if it is stored in the registry. Since we have a new build system it is much easier to create shared libraries, I’ve created a public smbconf library now. The library can be used to setup Samba or Winbind without touching any files. Ok, smb.conf needs one...
Maybe you ask: Why is there still no new version of lomoco to support the latest Logitech Mice? The answer is that I still don’t know how they detect a mouse connected to a receiver. Maybe they just have a table which defines which mice come with which receiver and then try some commands. If it fails it is mouse X and if not it...
Maybe you’ve heard already of the privacy aware, personally controlled, open source social network Diaspora. I’ve wanted to try Diaspora so I’ve setup my own seed of Diaspora, they are called pods. I don’t wanted to run Diaspora with thin so I decided to go with mod_passenger on apache2. I will describe what you need to do to set it up and get it running...
At the end of last year I’ve worked on Dogtag PKI, which is enterprise-class open source Certificate Authority. The project is written in serveral different laguages (C, C++ and Java), so I’ve used CMake as the new build system. I know CMake very well and use it since a long time. To be able to build the java project I needed Java support in CMake....
Last year I discovered Mozilla Weave (now Sync). Weave is a Firefox addon and they offer the server components to install your own weave server. It offers everything I would like to have for PIM. So lets start with some details… The Firefox Sync addon synchronizes the following things between your browsers/computers: bookmarks history forms prefs tabs passwords The data stored on the weave server...
I wanted a simple command to get a backtrace in a file from gdb. It took me years to finally discover and craft this command! alias bt=’echo 0 | gdb -batch-silent -ex “run” -ex “set logging overwrite on” -ex “set logging file gdb.bt” -ex “set logging on” -ex “set pagination off” -ex “handle SIG33 pass nostop noprint” -ex “echo backtrace:\n” -ex “backtrace full” -ex “echo...
