MDADM RAID Failed After Upgrade from Ubuntu 8.10 to 9.04

Peter — Fri, 24 Apr 2009 07:37:03 +0000

With no surprise the update from Interpid Ibex to Jaunty Jackalope was not as easy as I hoped. After booting the fresh 2.6.28 kernel I was welcomed with “Press enter for maintenance (or type Control-D to continue)” and errors when trying to mount my RAID0. After some investigations found that the devices are now named [...]

One not-so-beautiful morning I woke up just to find out that my Seagate 7200.11 500GB hard drive is not detected from my BIOS. Unfortunately it was a well know problem which have three solutions: Replace the hard drive with new one from where you got it and lose your data Send it to Seagate for data recovery [...]

Wordpress Video Galleries with NextGen and jQuery

Peter — Thu, 09 Apr 2009 18:36:13 +0000

For one of my recent Wordpress projects I needed an easy way for the client to organize and display videos. Unfortunately my hope that NextGen Gallery plugin, which I already used for the images, will do the trick vanished after couple of clicks and I started googling for a solution. Since neither google nor Worpdress [...]

FLARToolkit, Papervision3D and the World of Augmented Reality

Peter — Mon, 02 Mar 2009 17:14:12 +0000

In the past couple of weeks I’ve been working on couple Augmented Reality (AR) projects for row27 Studios including the newly released “Oski on your Desk” mini site dedicated to the Californian Golden Bears’ mascot Oski. It was quite interesting to see Papervision3D’s superpowers combined with FLARToolkit with all the limitations and difficulties connected with it. If [...]

Papervision3D: Getting Started with Adobe Flex (Screencast)

Peter — Tue, 27 Jan 2009 20:42:06 +0000

After completing my personal website I started considering the idea of recording some video tutorials and as a result I have just done my first Papervision3D screencast. One thing I am very pleased with is the technical part of this task. Since I’m not a big fan of Camtasia and other propriatery software this time [...]

MooTools vs JQuery vs Prototype vs YUI vs Dojo Comparison Revised

Peter — Fri, 16 Jan 2009 16:10:24 +0000

Update (02-03-2009): Recently things are going a bit beyond the healthy conversations and various people are taking the whole “which-is-the-fastest-framework” idea way too seriously. The most important thing in any benchmarking process is not to compare apples to oranges, which unfortunatelly happens too often. After jQuery adopted Sizzle (a selector engine) many people started comparing it [...]

How-to Increase Adept’s Font Size under KDE4 (Kubuntu)

Peter — Mon, 05 Jan 2009 17:16:48 +0000

One issue that was bugging me for a while was the different font size (after adjusting it) on couple applications (including Adept) under my fresh installation of Kubuntu Interpid. After investigating and Google-ing I found out that it was due to running those proccesses as “root” which had different fonts and GTK+ settings. Solution: $ kdesudo systemsettings After [...]

VMware Player / Workstation Keyboard Mapping Problem

Peter — Mon, 05 Jan 2009 16:30:17 +0000

After switching from Debian Unstable to Kubuntu 8.10 I reinstalled my VMware Player 2.5.1 and started my Windows XP virtual machine. Soon I found that most of the keys near the numeric pad (del, home, right enter, etc) are either not working at all or doing wrong things. The obvious reason was some wrong [...]

Re-Launching CreonFX.com

Peter — Thu, 18 Dec 2008 12:12:22 +0000

It’s been quite a while from my last post but I have not been losing my time in this period. Retrospection: After some unfortunate events the company I was working for just disappeared and many good people were left on the street. Beside the obvious issue with the lack of incomes finally I could start working with [...]

Facebook Style Image Cropping (Javascript Preview)

Peter — Tue, 26 Aug 2008 19:10:13 +0000

While others are sun bathing somewhere on the shores of Black Sea I received another interesting task – to implement cropping for user uploaded profile images. My first idea was to port MooCrop to Mootools 1.2 and apply couple of modifications, but the customer wanted the cropping to be exactly like in Facebook. For those [...]
