Yes, Panda Challenge is going to start.

It’s summer time, daylights are longer and we have some extra spare time to enjoy doing some reversing, don’t you think? Some weeks ago we launched in Spain a reverse challenge, and even though we had more than 800 answers, no one was able to solve the 3 different challenges.

After few sleepless night, “full” porting of Ruby over to Android finally works. Porting Ruby over to ARM platform is pretty much tricky but it is very cool project.

To make sure most of the RoR stuff work, my target is to get Metasploit 3 runs on Android. Running a full Metasploit is pretty much at Android emulator. But I guess at least I am reaching some where.

So for people who loves Ruby, doing RoR on Android will be a cool stuff. I At this stage, I’m not sure what type of benefits it will bring to the RoR developers. But i guess this is pretty much a good alternative for RoR loves, alternative for Java :)

Well, I did not code anything on RoR (UI design is alwats a hardjob) , but I do code alot on Ruby. Again, Rails not Ruby.

Finally, I got Android running HTC TyTN II (Kaiser).

Thanx to XDA-Developers forum and lgorris. Things are pretty much unstable. It might be due to the original ROM is not too workable.

According to lgorris,

Google Android:

*make sms work
*make phone calls more stable (if the other side hangs up, dialer is frozen and connection kept up)
*get more overall stability (get rid of the random hangs; data connections always cause hang after some time)
*wait for sourcecode/better working binary blobs
==> ask dzo for his reverse engineer’D rilphone library code (that’s what provides the AT communication and so) and go improve it; dzo is the same person who put together android.bin

I guess still pretty much long way to go.

At this moment, Go and get a HTC Dream from T-Mobile :)

Update : 16th September 2009

Ruby and Busy manage to run peacefully in Google Android. Tested with some tools from ortegaalfredo. ortegaalfredo manage to compile strace gdb and bash to run in Android.

Some Small ScreenShot from Android :

bash-3.2# cd /data/opt/bin/
bash-3.2# ln -s ./busybox uname
bash-3.2# ./uname -a
Linux localhost 2.6.25-00350-g40fff9a #1 Wed Jul 23 18:10:44 PDT 2008 armv5tejl unknown
bash-3.2# /data/usr/bin/irb
irb(main):001:0> 1+1
=> 2
irb(main):002:0> exit
bash-3.2#


How can can we move on with Iphone ? or I am too poor to buy OpenMoko.

What’s Next for Android ? :) Stay Tune.
