বহুদিন ধরে’ বহু ক্রোশ দূরে

বহুদিন ধরে’ বহু ক্রোশ দূরে
বহু ব্যয় করি বহু দেশ ঘুরে
দেখিতে গিয়েছি পর্ব্বতমালা
দেখিতে গিয়েছি সিন্ধু।
দেখা হয় নাই চক্ষু মেলিয়া
ঘর হতে শুধু দুই পা ফেলিয়া
একটি ধানের শিষের উপরে
একটি শিশির বিন্দু।।

HOWTO on running Tizen on ArchLinux (using Ubuntu chroot)

Here is my honest confession about Ubuntu and Tizen. I seriously dislike them as they are bloated and designed & developed by nuts. Anyway, I wanted the Tizen SDK to run on my ArchLinux box (for code review & curiosity).

Here is the HOWTO on running Tizen on ArchLinux (using Ubuntu chroot) : I know it is SICK!!

Create preliminary Ubuntu chroot in ArchLinux :

1. aurget –deps -Sy –nodiscard –noedit –noconfirm –asroot debootstrap

2. mkdir /home/ubuntu-chroot

3. cd /home/ubuntu-chroot

4. debootstrap –arch=amd64 quantal ubuntu-quantal-amd64 http://192.168.17.10:3142/archive.ubuntu.com/ubuntu/

5. ln -s /proc/mounts ubuntu-quantal-amd64/etc/mtab

6. rm ubuntu-quantal-amd64/etc/resolv.conf

7. echo “nameserver 8.8.8.8” > ubuntu-quantal-amd64/etc/resolv.conf

8. echo “log:x:19:” >> ubuntu-quantal-amd64/etc/group

9. update /etc/apt/sources (curl http://192.168.17.10/public/apt-cacher/sources.list > ubuntu-quantal-amd64/etc/apt/sources.list )

Chrooting to Ubuntu chroot :

10. cat chroot-to-ubuntu.sh

xhost +
mount -o bind /proc/ ubuntu-quantal-amd64/proc/
mount -o bind /dev/ ubuntu-quantal-amd64/dev/
LC_ALL=en_US.UTF-8 chroot ubuntu-quantal-amd64 bash
killall -gq dbus-launch

killall -gq /usr/lib/rtkit/rtkit-daemon

sleep 3
umount ubuntu-quantal-amd64/proc/
umount ubuntu-quantal-amd64/dev/

Setting-up Ubuntu chroot :

11. apt-get update

12. apt-key adv –keyserver keyserver.ubuntu.com –recv-keys 16126D3A3E5C1192

13. apt-key adv –keyserver keyserver.ubuntu.com –recv-keys C2518248EEA14886

14. dpkg-divert –local –rename –add /sbin/initctl

15. ln -sf /bin/true /sbin/initctl

16. apt-get -y –no-install-recommends install locales wget curl debconf devscripts gnupg vim aptitude mc

17. apt-get -y –no-install-recommends install build-essential git-core

18. locale-gen en_US.UTF-8

19. update-locale en_US.UTF-8

20. ln -sf /usr/share/zoneinfo/Asia/Kolkata /etc/localtime

21. adduser USERNAME

22. gpasswd -a USERNAME root

23. gpasswd -a USERNAME users

24. gpasswd -a USERNAME sudo

Apps/themes [optional] :

25. apt-get -y –no-install-recommends install vim-gtk

26. apt-get -y –no-install-recommends install gtk2-engines-oxygen gtk3-engines-oxygen oxygen-icon-theme

27. echo “gtk-theme-name = \”oxygen-gtk\”” > /etc/gtk-2.0/gtkrc

28. echo “gtk-icon-theme-name = \”oxygen\”” >> /etc/gtk-2.0/gtkrc

29. echo “gtk-font-name = \”Liberation Sans 9\”” >> /etc/gtk-2.0/gtkrc

30. cat /etc/gtk-2.0/gtkrc > /etc/gtk-3.0/gtkrc

Preparing for Tizen development :

31. apt-get –no-install-recommends install oracle-java6-installer

32. apt-get -y –no-install-recommends install procps gettext libdbus-1-3 libcurl3 expect gtk2-engines-pixbuf grep zip make qemu-user-static libwebkitgtk-1.0-0 libgnome2-0 pciutils libxtst6 libglu1-mesa libv4l-0

33. apt-get -y –no-install-recommends install xdg-utils unzip

34. apt-get -y –no-install-recommends install qemu-kvm

35. su – USERNAME

36. mkdir -p ~/.local/share/desktop-directories/

37. wget http://download.tizen.org/sdk/InstallManager/tizen-sdk-2.0-ubuntu64.bin

38. bash ./tizen-sdk-2.0-ubuntu64.bin

39. su – tizen-dev

40. /home/tizen-dev/tizen-sdk/ide/startup.sh &

 

New year morning 2013

Today I woke up and Aditri greeted me with a big smile. Can’t expect a better new year morning.

Xoom-ing into ICS

I got really impatient due to non-availability of ICS/JB for my Motorola Xoom MZ601. So, I decided to hack and switch to MZ604 firmware for GED Xoom to receive OTA update of ICS build. I had to compromise with non-working 3G, but it is okay for time-being …(till my next hack).

Here is the quick howto :

1. Make sure to have adequate (full) charge in your Xoom.
2. Download the official Build HWI69 for US Retail from Motorola device software page.
3. Switch to fastboot mode by holding “vol down” + “power” buttons (ref).
4. Connect the Xoom with Computer (Linux/Windows/Mac – assuming that you have the Android tools/drivers installed).
5. Run following commends from terminal (you may void your warranty)
   • fastboot oem unlock
   • Following on-screen instructions.
   • fastboot reboot
6. Once rebooted, switch back to bootloader
   • adb reboot bootloader
   • Wait for the reboot and switch to fastboot mode
   • From the terminal change to MZ604 firmware directory where you unzipped official Build HWI69 for US Retail firmware.
   • cd /home/experiments/MZ604_HWI69/
   • fastboot flash boot boot.img
   • fastboot flash system system.img
   • fastboot flash recovery recovery.img
   • fastboot flash userdata userdata.img
   • fastboot erase cache
   • fastboot reboot
7. Once rebooted, you will get HW169 firmware loaded into Xoom.
8. Connect to WiFi and do system update (OTA process).
9. You should get automatic OTA which will upgrade firmwares in sequence :
   • HMJ37 -> HTJ85B -> HTK55D -> HTK75D -> IML77
10. Once you have IML77, you are into ICS (android ice cream sandwich 4.0)
11. Finally, a factory is not a bad thing to do.

Enjoy.

Did I forgot to say that I am not responsible for any damages caused by using above instructions?

Our new car – WagonR 2012

Today parents bought their new new Maruti Suzuki WagonR. I am sure, parents, Soma & Aditri have lots of exciting plans with this one.

Nice interior, decent engine and pick-up, a nice package in good price. A good small car of the family.
