android-x86 nightly builds are back

I started to build my own images but nightly builds for android x86 are back
http://android-x86.moonman.dk/

Downloaded the gingerbread version dd it on the usb stick

sudo dd if=eeepc-20110427_usb.img of=/dev/sdb
sync

and rebooted the eeepc with the new image
wow how fast it is !

ps: got this issue (android skipping incompatible /usr/lib/libz.a when searching for -lz) when building gingerbread on debian 64 but was easy solvable :
sudo apt-get install ia32-libs g++-multilib gcc-multilib lib32z1-dev lib32ncurses5-dev

add haiku in grub2 also make bootable stick after build

I have made the bootable stick this way after my generic image finished

cd haiku/generated
dd if=haiku.image of=/dev/sdb
sync

add the next entry in grub2

sudo gedit /etc/grub.d/40_custom

for me the partition prepared is /dev/sda3

menuentry "Haiku" {
    set root=(hd0,3)
    chainloader +1
}

then update the grub config

sudo update-grub

Recovering grub with debian live usb stick

unetbootin didn't worked with creating the bootable android 2.2 so i in the process i have made debian unbootable
If you read the manual there is a live cd image (also there is the usb stick version )

I have downloaded the lxde version for i386
then written the image directly to the stick

cat debian-live-6.0.1-i386-lxde-desktop.img > /dev/sdb
sync

reboot

next is grub reinstall

Update: i have found that there is a debian Live EEEpc version , i will try that instead

dd if=eeepc-live-1.1~rc1-hybrid.iso of=/dev/sdb
sync

Update2:
Debian eepc works better so now i have chrooted and reinstalled grub this way

$sudo su 
# mount /dev/sda1 /mnt
# mount --bind /dev /mnt/dev
# mount --bind /proc /mnt/proc

Now chroot into the enviroment we made :

# chroot /mnt

Now install/recover Grub2 via :

#grub-install /dev/sda

booting Android from a Cheap mp3/mp4 player on my eeepc

my usb stick is not booting anymore , i guess is time to buy another so i had a cheap mp3/mp4 player with z80 cpu ?!!

lsusb: ID 10d6:1101 Actions Semiconductor Co., Ltd D-Wave 2GB MP4 Player / AK1025 MP3/MP4 Player

i formated the /dev/sdb as ext4 just to be sure
then used the usual android usb instructions

zcat android-x86-1.6-r2_usb.img.gz | dd of=/dev/sdb

Android booted quite niceley on eeepc with wireless and all
next is to build the 2.2 / 2.3 image and burn it on the player's partition
I wanted to test the quake on it but it said that sdcard is not present
so i have to mount somehow the sdcard(the debian parition) and
install from there (put the data there)

Building haikuos adding devel packages like gcc + git

you can ad your custom build config the devel packages in cases you want to compile inside the image

create the file

build/jam/UserBuildConfig

the devel packages (jam seems to be very sensitive to space and ";" at the end )

AddOptionalHaikuImagePackages Development ;
AddOptionalHaikuImagePackages Git ;
AddOptionalHaikuImagePackages DevelopmentBase ;
AddOptionalHaikuImagePackages DevelopmentMin ;

a good idea if you build the anyboot image is to increase the image size from 100 default to 400

HAIKU_IMAGE_SIZE        = 400 ;

then you can build the image with the simple

jam -q

Next is howto figure it out how to make it install on /dev/sda from the jam file (auto install on partition) it said it installed but it couldn't boot yet

Securing Firebird 2.5 SuperClassic in Debian / Ubuntu

apt-get install firebird2.5-superclassic
dpkg-reconfigure firebird2.5-superclassic

Choose a good password

vi /etc/firebird/2.5/firebird.conf

add only the localhost to the Remote Bind Address (we listen only on it and nothing else)

RemoteBindAddress = 127.0.0.1
DatabaseAccess = Restrict /var/lib/firebird/2.5/data/

restart super classic

sudo service firebird2.5-superclassic restart

check if it listens on localhost ip only

netstat -tap | grep gds
tcp        0      0 localhost:gds_db        *:*                     LISTEN      2129/fb_smp_server

There are more ideas : running apache + php in a chroot , adding apparmor rules
maybe we need a chroot feature in firebird in the future

#Microsoft Lifechat LX-3000 headphones +sound card on !ubuntu natty

The device specs are here
I have plugged and it was recognized in sound preferences but no sound output (there was nothing to select there after i disabled the main soundcard) so sudo Restart
and all was ok (on another coleague machine it worked out of the box without the need of restart for sound output)

So yes they can write on the box Optimized for Ubuntu/Debian/Gnu Linux , even the Sound volume buttons work ok (+/-)

Microsoft Hardware Looks cool on Linux only

Nouveau part three : libtxc-dxtn on #debian

I found a way to fix nouveau libtxc_dxtn.so loading errors with the following repository

wget http://debian-multimedia.gnali.org/pool/main/libt/libtxc-dxtn/libtxc-dxtn0_1.0.0-0.0_amd64.deb
wget http://debian-multimedia.gnali.org/pool/main/libt/libtxc-dxtn/libtxc-dxtn-dev_1.0.0-0.0_amd64.deb
sudo dpkg -i libtxc-dxtn0_1.0.0-0.0_amd64.deb
sudo dpkg -i libtxc-dxtn-dev_1.0.0-0.0_amd64.deb

nouveau from git was to unstable so i loaded the one from debian (glxgears was black today so i went a few steps back)

sudo apt-get install libgl1-mesa-dri-experimental

or

sudo apt-get install libgl1-mesa-dri-experimental -t experimental

Installing Haiku-os on a partition from within Qemu

I build my own haiku images so this is a easy way to install and test on my machine

add new partition with fdisk /dev/sda
change the type to bfs
start qemu

sudo qemu -cdrom haiku-cd.iso -hda /dev/sda4 -m 1024

start installer , format the partition and then do the real install on that raw partition

stop the qemu when it finishes ctrl-c

start the new installed machine

sudo qemu  -hda /dev/sda4 -m 1024

later you can add it in grub menu to start it from there directly

Opengl this is what i call well defined api

Dowoload the redbook 1.1 samples , unzip them
install the various mesa headers (you will figure out it's easy)

and then it compiles without errors and works out of the box !

gcc aaindex.c -lglut -lGL -lGLU
./a.out

ps:this is code from 1997
