So you have this linux box and you want to add an extra harddrive without having to reboot it. The key command we’re looking for, is a way to rescan the scsi bus. This can be achived by rewriting some values in the /sys synthetic filesystem:
echo "- - -" > /sys/class/scsi_host/host#/scan
Replace the digit for the scsi host as appropiate.
If everything went well, you should get output on the console indicating it detected a new hard drive.
Main feature in this release is the widget! It reflects current login state and clicking on it opens the activity.. I also switched to using the AndroidHttpClient explicitly to allow proper resource cleanup although I’m not sure that won’t give any problems for pre-Froyo platform users..
Changelog
+ widget: shows login state, click on widget to open activity
+ activity: show last login time and ip
* service: correctly parse json response to allow proper logout
* service: moved logout action into service
* service: use AndroidHttpClient instead of HttpClient to avoid IllegalStateExceptions
* service: don’t attempt login on portal error
+ activity: initial localisation support
Changelog
– fc bugfix on portal connection failure
– fc bugfix: intent may be null on service restart
– log ip on successful logon (trying to find connection refused problem)
Changelog
– complete refactor: service based login, no activity dependency anymore
– automatic login
– parse json portal replies to return adequate errors
– logout function (also requires json)
– detailed login feedback
Note: the beta app is a separate app from the stable one.
Debugging your android app using a hardware device has several advantages, ie faster and more testing possibilities. On windows you have to install a custom USB driver, on linux it’s a matter of configuring your udev rules:
/etc/udev/rules.d , ie 44-android.rulesSUBSYSTEM=="usb", ATTR{idVendor}=="0bb4", MODE="0666", GROUP="users"and adapt the vendor id using this table.
udevadm control --reload-rules When you run adb devices, it should now list your device:
List of devices attached
emulator-5554 device
SH14FPL06953 device
Before, you would rather have something like this:
List of devices attached
emulator-5554 device

Note that it seems normal that a usb storage device is detected, although I did not have it enabled on the phone.
One month ago, I bought an android smartphone and a few days later my first app was born: UZLGastennetLogin! =)
Note: This app is only useful to people working at or visiting the University Hospitals Leuven.
At UZLeuven we have a separate network to provide internet access to alien/untrusted devices: patient, visitor or external company laptops, tablets, smartphones etc. You need a personal access code to access this network though. When you are not logged in, any website you try to access, redirects you to a login portal.
There are 2 problems using this network on a smartphone:
This is where the app will come in handy:
The first version of the app allows only manual login, but it already saves you from using the webinterface and re-entering your credentials over and over again. Today, I published it on the market.
Yesterday I made this awesome flying finish in Colin McRae Dirt 2 and wanted to view the replay only to realize: there is no replay? That sounded impossible and today, after missing another fine opportunity, I decided to go to the bottom of this. 🙂
Turned out Dirt 2 automatically disables the replay functionality behind your back when there is insufficient free space on your OS partition! That’s right:
IMO, this is just another example of why consolisation of excellent PC games like CMR is BAD. Anyway, don’t let me go there, let’s focus on hibernation in win 7. 🙂
So I have a 20GB partition for Wintendo 7, but with only 1GB free that does not seem to cut it. Turns out about 6.5GB is taken by the hibernation file (I have 8GB RAM) which I don’t use. So, how to disable that in windows 7? Open a command prompt as administrator and type:
powercfg.exe /hibernate off
That’s all.
Ever felt lost on your desktop? Or more precisely: unable to find your mouse pointer within a (few) second(s)? I know I have, and nowadays on 2 monitors or more (or a huge 48″ tv), this isn’t an exception.
In KDE, we always had the track mouse effect which draws circling yellow stars around your pointer. Unfortunately, this is not adequate anymore. That’s why I thought it would be fun to write my own effect which would do a better job. The key to success seems to me that it should be a full screen effect drawing the attention to the right spot no matter where at the screen you’re looking.
For now, I’ve devised 3 effects:
For the last 2 effects, I don’t have screencasts yet, don’t ask, I’ve been through hell to create the first one. Also, for the last one, I have to fix the texture uv map generation, or use a better mesh (or maybe a different technique 🙂 ).
Changelog
– show last refresh time in tooltip
– on error, keep retrying with increasing interval
