a cosmological pedestrian
I’ve had the problem that the device didn’t want to switch into deep sleep mode if radio was on. What is deep sleep? To make it simple we break it down. Your device has 3 modes. The fisrst is “Screen On and Awake”, “Awake” and “Deep Sleep”. If you use your device it you’re in the first mode and you need a obviously a lot...
If you try to get a new Android version, in this case CyanogenMod9, working on your old phone you have to deal with binary blobs. One of these blobs is the library talking to the radio, libhtc_ril.so. I wanted to document what I learned about libhtc_ril.so. I’ve wanted to get the library version matching my baseband version working with cm9. This resulted it several segfaults....
After Qualcom released new graphic blobs for ARMv6 I was able to get CyanogenMod 9 working on my HTC Wildfire S pretty well. There are still some problem which need to be fixed. GPS isn’t working, if you have GSM/3G turned on the battery drains pretty fast. I’m currently trying to get the camera working. There is also a wakelock bug with bluetooth in the...
I’ll show you how to to synchronise files of two different directories in a terminal using a mighty automator. The tool is called csync and is a client side file synchronizer. Unless like rsync it syncs in two directions so that the contents are equal as soon as it finished. Here is the simple example of syncing two folders from terminal: csync /path/to/folder1 /path/to/folder2 If...
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...
