12minutes: Chromium OS Internals: How to start X application = Using aterm to copy outputs directly to blog ?

⟾ 12 Minutes: Chromium OS Devel version of image have installed useful tools like aterm which is running under X ,
so we can copy commands and their outputs directly to Blog opened in Chrome Browser.

Get to shell first

Ctrl-Alt-t
shell

You now have text terminal with X session

echo $DISPLAY
   :0.0
xdriinfo
   screen 0: i915
xdpyinfo | grep visual: | wc -l
  57

Start aterm in background with scroll back buffer 99000 lines and exit shell

 aterm -sl 99000 &
[1] 1796
disown %1
exit
exit

Now you can switch between Chrome and aterm – copy – paste stuff

Use Alt - Tab to switch windows
Select text in aterm with left click and mouse over
Paste in blog text filed with middle mouse button

12minutes: Chromium OS Internals: Installed packages and their sizes on default devel image

⟾ 12 Minutes: Chromium OS Let’s look for complexity of Chromium OS from JeOS (reduced install) point of view,
so we can compare it later with my past OpenSolaris X JeOS reduction targets:

Is there any RIGHT way we can find which packages are layered using dev image ?

12minutes: Building Chromium OS image in 12 steps on ATOM nettop HW using REPO

⟾ 12 Minutes: Chromium OS Here I will like to share my experience compiling and building Chromium OS image on
relatively low power ATOM netbook or nettop like HW using new REPO command.

Chromium OS is 32 bit system, but you need a 64bit Linux system to build it on,
you can also utilize tricks for low power systems bellow on old 64bit Duron/Athlon with similar power of my nettop like
1.6Ghz ATOM 230 and D510 configurations

Here is my 12 steps for Compiling and Building Chromium OS USB Image:

Last Update for: 0.9.125 2010/11/20 1314

Timing notes: Build process access Internet, my connection is DSL 3Mbit which I can in most cases fully utilize.

12minutes: How will Web OSes and Web Desktops change Cloud Usage Patterns ?

⟾ 12 Minutes: Chromium OS On CloudCamp & CloudExpo Prague 2010 we spend significant time during coffee breaks mapping how future of Cloud
based services and solutions will be influenced by new type of users which will live truly just in Cloud..

We identify then Web OSes and Web Desktops will plays a significant role in this user behavior shift.
