Changing window control layout in Ubuntu 10.04 beta

April 12th, 2010

Some changes in Ubuntu are really annoying. Switching from esd to pulseaudio was definitely my favorite for 2009.

The window control button change currently running in the 10.04 beta is a canidate for this award in 2010.

Here is a quick and dirty fix in order to allign your controls to the right side of the window using the gconf-editor (note to Windows Users: this is almost as using the Registry Editor):

  1. launch gconf-editor from a console
  2. switch the directory tree to apps –> metacity –> general
  3. find the key named button_layout
  4. change the value to menu:maximize,minimize,close,
  5. take a deep breath :)

Android: Using your local Amazon MP3 shop with WWE Roms

April 12th, 2010

Some Android custom Roms are only available in WWE (World Wide English) which is not really a big deal. However there are a few exceptions when it comes to native characters or services based upon your locale.

Since I live in germany, i have a german Amazon account which I use for online purchase including my music.

When downloading AmazonMP3 from the market, the application will check your locale and set the Amazon Shop accordingly. In most cases of WWE Roms, this will be AmazonMP3(US) and you wont be able to purchase MP3s with your native account (DE in my case).

Using morelocale 2 you can manually set your locale to your preferred area and you should be able to use your native provider ignoring the WWE locale on your phone.

HD Playback in Ubuntu: VDPAU on an ION Netbook

March 24th, 2010

GPU Video enhanced playback is becoming more and more important with the availability of low cost Netbook and Nettop CPUs.

If your device features an ION gpu (such as my Lenovo S12 netbook) you will be able to playback even 1080p HD Videos using VDPAU in Linux. These implementations are also available for Windows as DXVA (Direct X  Video Accelleration) or NVIDIAs CUDA interface (which is not limited to enhancing video performance).

To use VDPAU simply follow these steps:

  1. make sure you are using the restricted NVIDIA drivers
  2. grab a trailer from http://www.h264info.com/clips.html – I used the 1080p Simpsons movie trailer
  3. download mplayer-nogui: apt-get install mplayer-nogui
  4. playback using vdpau: mplayer -vo vdpau -vc ffh264vdpau The\ Simpsons\ Movie\ -\ 1080p\ Trailer.mp4 vdpau
  5. For comparison: mplayer The\ Simpsons\ Movie\ -\ 1080p\ Trailer.mp4   novdpau
  6. When using a mplayer GUI such as smplayer or gnome-mplayer, make sure to select vdpau in the video playback options
  7. Enjoy Full HD video playback

Good News Everyone!

Season 6 is the upcoming season of Futurama and the first season of the second run. With 26 episodes, season 6 is so far the largest season, beating season 3 during the original run, which had 22 episodes.

From a broadcasting perspective, season 6 will be the seventh and the eighth broadcast season, with 12 episodes in 2010 and 14 episodes following in 2011,[3] which would make “The Mutants Are Revolting“ broadcast season 7‘s season finale as previously hinted.[4] Which will make episode 6ACV13 the season première of broadcast season 8, but given it is a holiday special,[4] broadcast season 8 may already start in December of 2010.

The première for season 6 – and thus broadcast season 7 – is scheduled for 24 June, 2010.[1][2]

RFC 5782: DNS Blacklists and Whitelists

February 20th, 2010

The Internet Research Task Force has released a Request for Comments for the Usage of Black and Whitelists

The rise of spam and other anti-social behavior on the Internet has led to the creation of shared blacklists and whitelists of IP addresses or domains.
The DNS has become the de-facto standard method of distributing these blacklists and whitelists.  This memo documents the structure and usage of DNS-based blacklists and whitelists, and the protocol used to query them.

Android 2.1 AOSP Rom: CKdroid

January 26th, 2010

A new Rom for the GSM Hero has been released, this time its a AOSP based Rom without Sense UI. Android 2.1 has some great improvements on the widget making Sense Functions nearly obsolete, so AOSP should provide you with enough comfort.

The CKdroid also features LiveWallpapers, a function implemented on the Nexus one. If you want to waste your Battery and Performance for some useless show off crap… Here you go. I remove them via ADB.

Included in this release is a hack which will give you 2 more homescreens – summarizing it up to 5 on a standard Android device.

7 homescreens on the HTC Sense devices was a litle much, 3 was bearly working for me on the AOSP release, so 5 should do perfectly fine.

During the installation i had a rather annoying bug in the Android Market that sometimes stalls the installation for hours. I just wish the free apps were available outside the market. Good thing I had a backup of all apps with Astro. So I pulled the apk file for Astro from the default backup location /sdcard/backups/apps/ and installed via adb push. After that, I restored all my apps which still requires you to acknowledge each app when reinstalled which is still very annoying but at least i don’t have to wait for the market to work again.

CKdroid is very stable with some minor performance issues and will be my current stable Rom for everyday use.
