Virtual insanity : Xp in Linux or Linux in XP.

A whole new deal. 

Very soon we will see a culture shift, A change how people interact on the computer scene. My prophecy is nothing less then the end of the almost relidgious ‘ OS- Wars ‘. From newbie to web-lord, we have all played the paralympic game of ‘ what’s the better OS’ Wether in forums, in chatrooms, in endless slashdot threads or even in the comfort of our own pub : We’ve all been there. Wether Xp is better then 2000, Why Mac Os is better then Windows , and we’ll never forget the face of our local Linux Guru foaming at the mouth after he had to endure your proclamation that Windows ME was the best operating system ever written. ( And he never spoke to you again. ) But very soon the question “What’s your operating system” will be replaced by “ What’s your Primary Os ?”. Any computer with a processor speed over 1.5 gigahertz is quite frankly a waste of money. You don’t see a specific speed increase when you buy a 3 gigahertz or more . Ok , Windows will boot faster , but that does not mean YOU can work any faster. I mean , the processor is not the bottleneck of the system.  The question is : What to do with all this extra operating system power … More eye-candy ? Perhaps Vista will be more then happy to gobble up a few million cycles just for Balmers personal pleasure.  OR .. we can make the cycles pay off by jumping on the virtualisation train.

 All aboard ?

What do you do when you have one OS running , but your computer can carry twice the load ?  Well , lets install ANOTHER operating system. I’m not talking Dual Booting here, I’m talking Virtualisation. Running a second Os , INSIDE the first one. The “Base OS” is the main operating system you are running, The “ Guest OS is a virtual version of an operating system neatly compressed into one file.

Why ?

I know what you are saying. But why “ma cher Knightwise” would i do this ? Here is why.

  • Perfect testing : The virtual machine you installed is just ONE FILE. After you install it , make a backup and start fumbling around. Messed up the Guest OS ? Just drag your copy back and you are good to go. You can easily install all kinds of operating systems without having to worry about partitioning.- Space and energy saver : Who said you had to stop with running just one Guest OS . Instead of bricking up your bedroom with countless pc towers you can now have them running as virtual machines on one machine. Needless to say you save money by just owning one pc, you save power cause you only have one power supply to feed and save valuable bedroom time with your space because she doesn’t have to be mad at you all the time for junking up the house with your old ‘test machines”.
  • Switchers trouble : I have seen people by a PC or a Mac just for that one task. I’ve seen people buy an extra pc for their on-line banking. I’ve seen switchers go back because they could not get a certain application working on a certain platform. Well, There is an end to switchers trouble and you have all walked through the gates of Sliders heaven (Sliders = cross platform users). Personally I wanted to switch my main machine to linux because I could not get MSN messenger running webcam sessions. (Microsoft does not want to clear  the code ) So .. I installed Ubuntu, ran Windows XP as a virtual machine and did the impossible, ran the two Os’es at once and did my Webcam stuff without any trouble. I run Xp on my mac for consulting purposes (when i need to get into a Windows network)  and I run Ubuntu in my Xp for testing everything out before I make changes to my ubuntu server.
  • Servers dream :  The crappy thing about running multiple servers at home is the fact that they eat power. Now you can run several ‘virtual’ servers on the same machine and just have one power supply to feed.

And how do i Do that ?
Before we start : Be sure you have enough memory in your Base Operating system. Each guest operating system requires a chunk of ram. The bigger the chunk, the better the speed. Also see that you have enough storagespace. Not only so the Guest OS can grow to its full potential (About 4 gig”s will do) you also want to make  backup copy’s of every clean installed os that you have.  Wether you want to run Linux in Xp or Xp in  Linux , you need the free vmware player . This is a free application that lets you use pre-built images of virtual machines. So you cant ‘build’ your own virtual machine , just use one that has been pre-built. Now this ‘building’ of a virtual machine tells the virtual machine how to act. Luckily I found THIS site where you can download FREE virtual machine configuration files for just about any operating system you wish. All you need are the installation cd’s of that OS and you are on your way.  I’ll be playing with virtual machine more as the week progresses and keep you posted on the results. Meanwhile my “ Piece de resistance “ is a screenshot of an msn webcam session in Windows XP , running as a virtual machine on my Ubuntu (base) workstation.  Sliders .. the end of our troubles is in side and we are virtually saved.

No propper MSN clone for the cross-platform community.

A lot of Chitchat. 

As a slider ( somebody who moves swiftly between operating systems like Windows, Mac and Linux ) I am often confronted with the question : What tool do I use for what  ? There are of course plenty of ‘switcher tips” out there to help people out who decide to jump from one OS to the other. These ‘switch-lists’ are composed of tables representing a certain application in one operating system , and its counterpart on the other side of the fence. For example : Microsoft Office on Windows has Open-office as its counterpart in Linux (and also in Mac OS). Some applications are called cross-platform , these are of course the ideal ones. An exactly identical version exists in all operating systems. For example : Firefox , or Thunderbird. All versions look and feel exactly the same no matter what OS you are on.
But sometimes you have to look for stuff that “looks” or “behaves just like” the original version in one operating system. Classic example here  is the Switchers nightmare MSN Messenger. Unfortunately insanely popular among Windows Users here in Europe. But : Microsoft clings to this little peace of software like there is no tomorrow. Deliberately setting back the versions that are brought out on other operating systems (like for example on Mac OSx) and not disclosing any code to the open source community so their IM clients would be able to interact with MSN Messenger. The result is the entire thing has to be reverse engineered to make it work.

dWhat about MSN ?
A question often asked is : What do I use instead of MSN on other systems. Now there are some viable alternatives out there, but the one most commonly found on both Mac and Linux systems is AMSN . This noble attempt at Msn messenger ‘approximation’ has been running strong for quite some years now. Their main concern was to be able to crack the hard nut of enabling cross platform msn audio and video-chat. A noble cause since Microsoft does shield that box of tricks very well to the outside world. Now the AMSN people said they cracked it. They had gotten in working. Onto the labs dear friends ! My first test ( video chat between my powerbook and my girlfriends Ibook) worked just fine .. behind the firewall. But once I tried to talk or send files to the outside world ? No go.. Amsn does not deal with NAT translation very well. ( Well , it can’t cope with it at all). Making matters worse : Amsn runs on the  Mac like a rhinoceros on a valiumtrip. Slow and jerky to respond and not at all reliable. So i’m back to my ‘non video chat’ enabled alternative ADIUM. A great, highly customizable, well supported alternative. The downside ? No video-chat (file transfer works excellent) AND only available on Mac.  As for a Linux alternative to MSN i’ve stuck with GAIM for being the better product.

A loss.
Too bad actually , I mean , these guys over at msn have a quite good cross platform product and are able to crack a fantastic nut in getting video-chat to work .. But then they get stuck on this simple thing like Nat transgression. Perhaps its time for all these ‘alternative messenger clients” to start working together and produce one kick-ass open source Messenger alternative and overcome one of the final pitfalls for users switching to a non Microsoft OS.

the new macbook pro.

Its here ! Its HERE ! 

I'm a calm person. Introvert, quiet, not easily impressed. Years on the edge of real and cyberspace have left me jaded and therefore not likely to be amazed or star-struck by new technology. As trends evolve and gizmos and gadgets whizz by I raise the preverbal eyebrow and sigh. BUT NOT TODAY ! 

Today i am jumping up and down with the release of the new Mac-book. Nono ! Not the i've-got-money-to-burn-so-what-the-hell macbook PRO ! (an overpriced over-pimped version of the powebook line) I'm talking about the next generation (long overdue) incarnation of the Ibook. I am NOT going to delve any judgement on the little machine until i actually have one in my hands  ( and am surely not one of those who thinks that no matter WHAT Steve Jobs thought up , has to be fantastic ) BUT I am going to run over the specs of this baby before I slam my Visa card down and BUY one.  `

The New Macbook 

I admit, I have been waiting for this new laptop by Apple. When the Macbook pro line came out I knew I was in over my budget and that one of those shiny things where not likely to appear on my lap anytime soon. ( And i sure as hell was not going to be Steve's personal 2000 + euro personal beta tester.) So i waited and waited for what was going to come. Since I bought my first Ibook some year and a half ago I have been pleased with it beyond belief. I love the little bugger. The best 1200 euros ever spent on a laptop. And now its successor comes along. Lets all take a moment and drool together shall we ? Widescreen 13,3 inch screen with a resolution of 1280 x 800 pixels. 1,83-GHz Intel Core Duo 512 MB Ram (i'm personally opting for 1 gigabyte if money permits me to.)  A 60-GB serial ATA hard drive on  5400 rpm (Bummer ,this should have been a 7200 rpm disk) A Combo drive (dvd-rom, cd-rw) Isight built into the display (owwwkey) Front row with apple remote.Now this looks pretty amazing for a laptop with a price-tag UNDER 1300 euros. you can also go for the 2 gigahertz version OR the BLACK 2 gigahertz version. The 2 gigahertz version is about 200 euros more expensive and to be quite honest , I don't think thats worth the money. The BLACK version is 200 euros extra (but you get a 80 gig hard drive).  Now the first reaction Nyana gave to this was : "black ? What do you mean .. black ?" A Black Mac ?  Well she was right. The black Ipod had made me frown , cause to be frank , the white Ibook I have is babe-magnet numero uno when you use it in a café. 'ooh look its white , its cute etc'.  I'm not an Apple snob but .. black ? no thank you. But black or white at first sight this baby looks like a tough nut to crack for same priced competitors. From personal experience I can tell that laptops around the 1000 euro price-point by for example Acer or Siemens have much poorer quality of design layout compared to even my "old" kevlar-coated (yes-yes) Ibook. Its like comparing a throw away tin foil barbecue to  a concrete super deluxe backyard super-stove.

One thing to rule them all.

 But time for the cherry on the pie when we look one step beyond the designed specs and see what loops we can let this baby jump through in the future. If we take BOOT-CAMP into account that lets us run Windows XP on this machine AND we look at the Linux versions that are compatible with the macintells we come to the next conclusion.  This is the sole and single sub 1500 euro computer laptop that will run the three biggest operating systems on the planet.

Needless to say .. as soon as I get my hands on one.. An elaborate review will follow.
