"In this post I show step-by-step how you can setup your own "Super computer cluster" using Ubuntu MPI Cluster from multiple machines with the goal of bruteforcing strong encrypted passwords with John the Ripper for academic purposes. Owners of quad core machines will also benefit from this setup as the "john" binaries found in the Ubuntu Repositories are compiled to run on only one core. I managed to decrease the time required to crack password hashes using this setup."

Well, my point was that it's even easier with Ubuntu Server. It's entirely barebones *by default* and you don't get any additional stuff unless you chose to install it.
But IIRC all I did in CentOS was select the 'minimal install' radio option. It was hardly a difficult process and I certainly wasn't there unticking all the programs and daemons I didn't want.
In fact one could even argue that CentOS had a few "default installs" and you just select which default profile you wanted.
In fact I seem to recall Ubuntu Server wasn't as "one click install" as you make out. I found there was still a lot of stuff pushed during the default install that I had to deselect (their cloud tools, auto-updates, etc).
However who even cares how few clicks a server install takes? You should only need to install the damn thing once. I don't even want to see the units reboot more than once a quarter - and even then only for critical kernel updates. So spending a little longer during the install is neither here nor there.
Other than Slackware it's probably the most BSD-ish of Linux distros.
You should give it a try.

You mean other than Slackware, Gentoo, ArchLinux.... :p
Seriously though I had installed Ubuntu Server last year and I really don't see what was BSD-ish about it. For one thing, it's the same SysV inits as Ubuntu desktop. One of the things that attracted me to ArchLinux was the elegance of it's BSD-like design - more so even then Slackware (not that I'm in anyway criticising the excellent work Patrick has done with Slackware). Ironically it's also more barebones than Ubuntu Server.
I don't mean this to slag off Ubuntu Server. It did surpass my preconceptions. But for me it just didn't bring enough to the table to make me want to switch my servers over.

Hmmm...can't recall seeing that option when installing CentOS 5.x but maybe it's just something I missed. I quickly learned NOT to select the "Server" install though.

Welk. I mean in terms of minimalism. Naturally it still have the SysV stuff. Also I am comparing it to monstroisities like RHEL, Centos and SUSe
It is of course not as simple and elegant as OpenBSD.
found there was still a lot of stuff pushed during the default install that I had to deselect (their cloud tools, auto-updates, etc).
Nope, they're all deselected during the install and you have to manually select them.
However who even cares how few clicks a server install takes? You should only need to install the damn thing once.
Those of us who install a lot of servers care
. Well, not that much really I just like the fact that I dont have to deselect anything during the install. excellent work Patrick has done with Slackware
Yep, Slackware is awesome although I do find the lack of proper package management more of a con than a pro.

At an event earlier today, Microsoft unveiled the next Xbox - the third model, but confusingly named Xbox One. The big focus was TV, integrated Kinect, and all the other stuff we all expected to be forced down our throats. I think it took them 25 minutes to actually come to what should be the core of the story: gaming. Nothing groundbreaking in the gaming department, except for how Microsoft intends to handle the used games market and borrowing games from friends: pay up, buddy!

The day has finally come! Jolla has finally announced the launch device for its Sailfish operating system - and by god this is a looker. It's decidedly different from other phones out there, but it has good specifications and carries a relatively reasonably price tag - EUR 399, and it's up for pre-order today, shipping in the fourth quarter of this year.

Why does Google get so much credit in the technology industry? Why, despite the company's many obvious failings, do many geeks and enthusiasts still hold a somewhat positive view on the all-knowing technology giant? A specific talk at Google I/O this week provides the answer.

"Windows is indeed slower than other operating systems in many scenarios, and the gap is worsening." That's one way to start an insider explanation of why Windows' performance isn't up to snuff. Written by someone who actually contributes code to the Windows NT kernel, the comment on Hacker News, later deleted but reposted with permission on Marc Bevand's blog, paints a very dreary picture of the state of Windows development. The root issue? Think of how Linux is developed, and you'll know the answer.

This is one of those news items that's fun to write, fun to read, fun to comment on, and where no one will be able to say anything unkind. It's all just one big ball of awesome fluffiness. TuneTracker, the BeOS radio automation software, has just released something very special: TuneTracker System 5, the first version designed entirely and specifically for Haiku. In fact, it actually includes Haiku in the software package. Better yet, TuneTracker also unveiled several system-in-a-box products - which have Haiku and TuneTracker pre-installed.

Exactly twenty years ago, a document was published that played a huge role in establishing the web as we know it today. Twenty years later, and this simple and straightforward document is proof of an irrefutable fact: while closed technologies can change markets, open technologies can change the world.

Oh multitasking. That staple of computing that got thrown out the window with many modern smartphones. We got some rudimentary thing in its place - but even as multitasking on phone and tablets improves, its user-visible side remains cumbersome. Windows 8 has a neat implementation, and now it's time Android follows in it footsteps.

They're here! Whether that excites you or not remains to be seen, but the Galaxy S4, which will most likely become the best selling Android smartphone of the year by a huge margin, has been reviewed by all the major sites, and there's lots of interesting conclusions in there - although I think most of you will get the gist.

Nokia has posted its quarterly results for the first quarter of 2013, and just like the quarters that came before, there's not a whole lot of good news in there. The rise in Lumia sales still can't even dream of making up for the sales drop in Symbian phones, and when broken down in versions, the sales figures for Windows Phone 8 Lumias in particular are very disappointing. In North America, Nokia is getting slaughtered.More Features »

I'm just a sucker for simplicity and vi, I guess. Plus Yast becomes obsolete as soon as you start doing serious configuration management.
