Just a sitrep

Heyho!

I couldn't update my blog because I learned a lot to my final exam, and this week I'll do it. After the F.E I'll post new things.

An own development - Debian 'n' Ubuntu on Spica

Hellooooo :-)

I made a mod for Android 2.1 Eclair and Cyanogenmod 8.3. The original idea is from Saurik(who is the father of Cydia) and Empas from samdroid.net.

You can run Debian on 2.1 Eclair and ubuntu with no GUI, and you can run Ubuntu with LXDE on Cyanogenmod.

Check this out for Android 2.1 stuff, and for Cyanogenmod go here.

PS: If you don't execute "exit" (without quotes) to shutdown Ubuntu (on CM), you will experience problems. Ubuntu won't boot up next time.
The solution is, edit the bootubuntu.sh, search for "export loopdev=/dev/block/loop3" line and replace loop3 with loop4.

YONIP Kernel

Respect!

Well, now, the most discussed thread on samdroid.net forum is Banjo's kernel, called YONIP kernel. It's for Cyanogenmod 8.3 and Spicagenmod, I'll show you how this kernel improve your phone.

NOTE: Banjo said this kernel is NOT WORKING ON ALL PHONES, BUT YOU CAN TRY IT ON YOURS.

• This kernel is an overclocked kernel, which means if you apply this kernel, your phone's processor's clock will run on 1GHz.
• It can provide better battery life.
• In Banjo's opinion the touchscreen will be sensitive.
• It makes your phone faster.

Tom3q wrote the framebuffer driver for Spica, that's why you can choose from 2 color depth, 16BPP and 24BPP.

• 16BPP: I think it's the standard color depth, you can make screenshot if you are in 16BPP
• 24BPP: Prettier colors, but you can't make screenshots.

Banjo makes his kernels with 2 schedulers. CFS and BFS. Banjo recommends that you'd better to convert your phone's filesystems to ext2/ext4. I suggest system&cache to ext2, data to ext4.(BFS is not compatible with RFS, and with the conversion the phone reaches better results in I/O operations, BFS can be maybe unstable, but responsive and fast) //I wrote about BFS in a previous post

CFS: Completely Fair Scheduler, it's the mainline Linux scheduler, you can read an article about CFS in Wikipedia. CFS is stable, and provides better battery life.

If you want to install this kernel, first make a backup from your working configuration! Before applying kernel, make a Wipe Dalvik-cache. You have to remove all the tweaks(pixiebob tweaks, ckMod ssswitch etc.)

Golden rule: Nobody is responsible if you transform your phone into a brick!

You can see the download links @samdroid.

Have a nice day! :-)

Sitrep about my phone.

Hi!

I thought I share my running configuration on my phone. Now, my phone's running Cyanogenmod 8.3, but I thought I migrate my phone's NAND flash storage to ext2/ext4 from Samsung's RFS filesystem, and try "Brain Fuck Scheduler "kernels.

The idea

The idea came from a hungarian developer called Xmister, he developed and shared the idea on samdroid.net forum. Thanks to him :-)

Why is it good?

Well, it can increase the I/O operation numbers, which you can see in Quadrant Standard Edition app.

Will it reduce my phone's flash's lifetime?

The answer is no. It didn't use much more the NAND than the RFS filesystem or YAFFS2. If I remember correctly, RFS is based on VFAT.

How to migrate, and what is BFS?

In standard Cyanogenmod 8.3 recovery you can convert your filesystems. I suggest system and cache to ext2, data to ext4. You won't lose any data, because the conversion method makes backup from your existing data. You need 350-400MB of free space on your SDcard. After the conversion you can delete the backup files. The whole conversion takes 5 minutes.

BFS: Brain Fuck Scheduler. A CPU scheduler, which was developed by an austral anesthesiologist, Con Kolivas. BFS is not compatible with RFS, that's why we converted the filesystems. The BFS-kernels make the phones very responsive and fast :-)

The samdroid.net kernel makers(Lukiqq, ch33kybutt(but he told me he no longer develop to our phones), Banjo,Xmister) made kernels with BFS, I use ckmod.004BFS(download it from here), it's very stable, makes the phone very fast, I recommend it. If you want to use Lukiqq's kernel, download it from here. I'll create a particular thread about Banjo's YONIP kernel a bit later.
There isn't any updates about Xmister's kernel, but you can also download his kernel from here.

Good luck good work :-)

My Ubuntu desktop (Ubuntu 10.04)

Hello!

I thought I drop few lines about my PC's desktop. I used Ubuntu 10.04 with Linux Mint 10 desktop before, but now I'm using Ubuntu with Gnome-do dock, Conky, and I also use Compiz Fusion desktop effects.

The dock can be installed with sudo apt-get install gnome-do command.

My desktop   

Enabling Compiz Fusion is not so difficult. Open a terminal, and execute this command: sudo apt-get install compiz compizconfig-settings-manager compiz-fusion-plugins-extra fusion-icon emerald

I'm using this effects. You can set up this things in Compizconfig-Settings-Manager.

• Wobbly Windows
• Desktop Cube
• Rotate Cube
• Animation Add-ons
• 3D Windows
• Water effect
• Paint fire on screen
• Shift switcher

and the previously adjusted settings by compiz. You can customize each settings :-) You can set up every window-managing possiblities such as Open animation, close animation, minimize effect etc.
You can do this in Animations menu. Try it :-)

And the panel called Conky. Conky is an "Advanced System Monitoring Tool". It can display the system usage, hard disk usage, memory usage and there are much more possiblities as you or me can imagine.
You can install Conky with sudo apt-get install conky command. You will have to edit your own, or download and modify an other person's configuration. My configuration is SethConky, you can download it from here.
You will have to find a howto-file in the archive, it explains you how to set up your conky. :-)

Good luck, have a nice theming-time :-)

Cut mp3 files with mp3cut

Hey!

On the other day I had to cut and save to an other file a part of mp3 file. It worked with Virtual DJ, because I had to cut just a 30sec. part. I listened to 30 sec. and that's it.

But how do you cut a 30 min. lenght part? Do you listen to 30 min.?

Probably not.

There is a great program, called mp3cut, which allows you to cut parts in a given interval. In Ubuntu you can install with this command: sudo apt-get install poc-streamer (because mp3cut is a part of poc-streamer package)

You can run mp3cut from terminal, and here's the syntax:

mp3cut -o outputfile.mp3 -t hh:mm:ss-hh:mm:ss inputfile.mp3

Example: There is an mp3 file, and we would like to cut a part from 00:05:00 to 00:07:00.

mp3cut -o outputfile.mp3 -t 05:00-07:00 inputfile.mp3

And that's it :)

Use and enjoy :)
