Installing Arch Linux on a Virtual Box (vs MS Virtual Machine 2007)

I wanted a simple way to run Linux on my Windows XP machine. I don't love Windows but I'm used to it and it does have some advantages, however that's not the point. At some time in one's career in IT one needs Linux (possibly to learn POSIX OS) and Cygwin doesn't quite cut it, especially if one has not much previous Linux experience...

Few Resources ?

I only have 1GB RAM and a few GB left on my HD so a light Linux is indeed in order for my situation. So I wanted a Linux distro with no GUI or visual Desktop Environment - it figures, since true Linux power comes in the shell "command-line" terminal - , and as well documented and easy to install as possible. Thus ArchLinux (which has a guide to install, plus a beguinners guide which walkes you through the install and setup processes and explains basic Linux workings) and its precompiled binary distribution for i686 resulted optimal from my PoV. Fianlly and accounting for the need of simplicity, pacman, the package manager program that comes with Arch (similar to apt-get [Debian, Ubuntu], yum [Fedora], or zypper [openSUSE]) installs many binaries officially supported by and the Arch community.

MS VM 2007 vs VBox

I originally setup a 512MB RAM "Other OS" VM on MSVM07 which can be downloaded free from MS. It worked and all but its slower than VBox, and it freezes sometimes beyond hope of state-recovery. The only advantage of MS Virtual Machine 2007 is native text copy-paste into the Linux terminal. I don't undersand why VBox doesn't have it... However, a very basic feature: audio, did not work for me.

*NOTE: When installing a virtual machine, the hardware it detects is whatever the host program (ie MSVM or VBox) exposes to it. These 2 programs in question have virtual hardware which shuold work with generic Linux drivers. For example, worrying about WiFi is unnecessary since the net adapter exposed by the hosts acts as a physical cable even if you're actually connected through your air port. Sound and Video should work out-of-the-box in that case! 3D video acceleration may be an exception.

My Virtual Box (non-commercial licence but not the OSE edition) "Arch-Linux" machine with the same amount of RAM may sometimes die due to insuficcient RAM but the state gets saved automatucally and the program warns about it. VBox has many more features than VM in terms of customizing your virtual computer, sound works for me, plus its Guest Additions are available for Linux (and also for Arch in its [community] package repositories). MSVM is out of the competition at this point.

Arch Install Notes

There's 2 ways to install Arch (download here), get a 400MB+ iso image with all the basic packages or a 160MB net-install iso to download all the packages during the install process. The netinstall failed once for me when I left the VBox inactive for a while, something went wrong mounting the linux setup files (/etc). Then again it could possibly happen to the full installer I assume. The advantage of a net install is, despite being slower and depending on an active Internet connection, that you automatically get the newest packages from the online repos, plus you'll have them in the pacman cache in case you need to downgrade later. Full install CDs normally come with slightly old package databases and no pkg cache remains from those original install pacs.

Arch Setup
Things you may want to do after installing:

* Install sudo if you haven't.
* Setup audio if you haven't.
* Install bash-completion (sudo, pacman, others [eg ls or externals, hg])
   - also check out the command history search customization and other bash/readline tips & tricks!

* setup a color prompt

... more comming soon

Other useful links:
arch packages "pacman"
postgresql setup
usb drives
* first, setup the captured usb drives in VBox and activate to find /dev/sdb (assuming usb-storage kernel module is loaded [others may be needed, use MOD_AUTOLOAD="yes" in /etc/rc.conf]) * no need to automount... works with /etc/fstab

World in Conflict Patches and CD Security bypass

World in Conflict has been one of the best recent stategy war games in the last years. I love the camera movement specially, although it takes some time to master.

Anyway, I got a (try-before-you-buy) version from thepiratebay [I recommend uTorrent as torrent client]. I only downloaded the original WiC 1.0 without Soviet Attack, but these files work for the expansion as well.

1. You´ll need the crack / fix to bypass SecuROM (flt-wic rar file) in either case. If you installed Wic + SA all-in-one skip to 4.

2. Then apply the 1st patch (get it from somewhere else [this is an official game release patch]) to the installation

3. Proceed to install Soviet Attack (the expansion)

4. Apply 2nd game patch (get it elsewhere)

Enjoy :)

Pickling a function defined interactively in Ipython doesn't work

Ipython's __main__ module is a "FakeModule" the ipython developers created to fix some bugs early in the otherwise very very useful package. So don't be scared if your user-defined top level (__main__) functions can't be pickled in ipython, the code will work when pickling other top lever module functions, only not the ones in __main__ defined interactively. OR simpy use the plain old python interactive console from command line.


Only constant of the FIFA World Cup 2010: Poor Refereeing!

Just a short comment this time

The USA (the "stolen" goal), Mexico (vs Argentina - the ultra clear unmarked off-side), England (vs Germany - another stolen goal!), and Portugal (vs Spain - the WTF red card) all suffered from the worst FIFA referees in years... 

I think in neither case was the poor refereeing decisions decisive for the matches’ final results (except probably with the USA) but taking morals into consideration they might very well have been. ..Mexico and England most notably, lost their patience soon in the game and ended up being trampled upon... And maybe, just maybe, that extra man lost to Portugal could have produced a tie.

Whatever... FU FIFA!!!

PS: Plus the damn FIFA official site videos are mega-slow to load, tonight they're not even working! Lets not buy their products, such as the following games:

Mi disco "Por fin soy Cool" en

Bueno no sé si se llama así, son una bola de canciones rokosas que grabé en 2008 en la escuela de música ararat. Se transmiten mis rolitas y una super entrevista que me hicieron también hace poco a horas desconocidas, se cicla el contenido diariamente por ahora así que salen bastante esas rolas :)
