I have been looking for 'working from home' to spend couple of hours on 'WISHFUL' projects with the hardware boards. But being a (new)contractor is difficult to get VPN access . This constraint made me to think of emulators. Among many available, Skyeye and QEMU caught my eyes. Skyeye being a derivitive of ARMulator and legacy emulating tool for ARM. QEMU has many more new variants of ARM(upto Cortex and ARM MP core) being emulated. The question is which one is better? I am going to find out by trying both !

Wednsday I tried skyeye Hardy Heron, its awesome. I can successfully emulate many ARM based boards. Check this out for the ARM CPU and boards simulated by skyeye.
I am going to try writing some asssembly code for AT91 open hardware board.

This weekend I will be trying QEMU.

By the way I got some cool hardware to work at office. I need to catch up some time to do something with it.

Being 'screen'ed

I will briefly write about a wonderful tool which I have been enjoying since many years.
screen is a terminal multiplexer. screen as any other terminal application manages many terminals. But screen differers from other applications with its core features like:
  • Remotely attach/detach to your same set of terminals running shells/processes from a different PC in network. (I love this!)
  • Unlimited searchable scrollback buffer
  • Quick switch between terminals
  • Session sharing between users(Exciting)
  • Easily turn on/off logging to file
  • Save the content of scrollback buffer to a file
Screen has many more features which makes your life easier.
Before actually running screen, it's important to understand the default command character is Ctrl-A.
So start exploring it by running command screen and then for help press Ctrl-A + ? (control and ?)
Also look for brief help by running screen -h

As you start using it you will get 'screened' (you will be concealed from danger !)

Nokia Morph Concept

Morph is a concept demonstrating some of the possibilities nanotechnologies might enable in future communication devices. Morph can sense its environment, is energy harvesting and self cleaning .
Morph is a flexible two-piece device that can adapt its shape to different use modes. Nanotechnology enables to have adaptive materials yet rigid forms on demand.

Looks awesome. I want these technologies right now and Linux running on it!!
