Single command Ubuntu LAMP stack installation on Desktop Edition…..

CLI, Linux, Opensource, Ubuntu
This used to be a pain in the butt. Lots of manual apt-get lines and config edits to get it to work. Weŕe talking about installing the LAMP stack onto a preexisting Ubuntu Desktop Edition installation. I used to do this backwards in the old days by installing the Server edition first (with LAMP) and then getting the graphical desktop goodies installed on top of that. That method still works, but I found out that LAMP stack install on a Desktop edition is a simple one command affair. As of the 7.04 release, the Ubuntu base system includes Tasksel. You can install LAMP using tasksel.sudo tasksel install lamp-server

Writing Moblin (and Ubuntu) USB images using dd in OSX

Apple, Linux, Macintosh, OSX, osx Server, Tutorial, Ubuntu
I came across this problem this morning, while writing the newly downloaded moblin USB image file. The concept is straight forward, plugin a 1GB+ USB stick into a functioning Linux or Windows box, make sure the stick is not mounted and use dd to write the disk image to the stick. Under OSX however the instructions for unmounting are slightly different, so here are the quick steps:Download the desired .img file Open a Terminal (under Utilities) Run diskutil list to get the current list of devices Insert your flash media Run diskutil list again and determine the device node assigned to your flash media (e.g. /dev/disk2) Run diskutil unmountDisk /dev/diskN (replace N with the disk number from the last command; in the previous example, N would be 2) Execute sudo dd if=/path/to/downloaded.img of=/dev/diskN bs=1m (replace /path/to/downloaded.img with…

Moblin OS rocks…..

intel, Linux, Opensource, Technology
Heard of Moblin yet....Intel's foray into designing a Linux distro. Moblin is an open source project focused on building a Linux-based platform optimized for the next generation of mobile devices including Netbooks, Mobile Internet Devices, and In-vehicle infotainment systems. I came across the promo video below and I have to say I'm impressed. I'm downloading the beta image file right now to give it a try on my brand new Aspire One D150. More to come soon.....

ROCKS Cluster: "Unable to run job: denied: host is no submit host"

cluster, Linux, Opensource, Rocks
I ran into this a couple of weeks ago and it's been driving me bonkers. I finally figured out what's wrong. I was just trying to get my feet wet using the Sun Grid Engine and figured I follow their instruction page and try out the example shell script and submit it using "qsub" command. I was doing this on the frontend machine that's been configured properly as a ROCKS cluster frontend. This was not working and the error I kept getting was "Unable to run job: denied: host "name_of_computer" is no submit host. Exiting."After googling around for a couple of days I found the answer (atleast the answer in my case). Issuing the following command solved my problem:qconf -as frontend-nameApparently the SGE roll does not setup the frontend node…

RightZoom: Maximize window button for OSX that actually maximizes

Apple, Macintosh, OSX, osx Server
One of the first things you hear a new mac/osx user complain about is the odd way the green "zoom" button works on the upper left hand of windows on Macs. The button behaves differently depending on the app - Finder and Safari sizes to best fit, iTunes’ zoom button switches between the mini player and the normal window, Mail goes full screen. Often times, the behavior differs from one app to another and many Mac users find this behavior inconsistent, unpredictable and disorienting to use.RightZoom provides a quick and easy solution for the zoom button's inconsistent behavior. It enables you to make the zoom button maximize the window to full screen when you click the green orb.By default, RightZoom makes a number of apps blow full screen when hitting…

Another mind blowing art installation……

Arduino, Art, Physical Computing, processing, Technology, wiimote
So what happens when an artist combines a 3D gaming engine, the power of blender and processing and a dash of human powered mechanical abomination? :-) Bince McKelvie describes his project:Lb to Sf via bike is an interactive installation/game that documents a bike trip my friend and I took from long beach to san francisco. The user rides a stationary bike through a the 3d world by pedaling forward and steering with the bike handle bars. The world consists of three mini games and a huge chunk of the california coast. I am going to be releasing a version that is playable on a computer without the hardware soon. It is made with the blender game engine, a bit of processing, a wii controller and the makingthings to sf…

Touchless, Gestrual Interface, Powered by Electrostatics

Art, Disruptive Technology, Electronics, Physical Computing, Video, wiimote, Youtube
Great video showing a bizarre and novel way of creating a gesture based interface. You literally touch nothing....Air.....and the interface does the rest. Pretty interesting project. According to Justin Schunick of the team at Northeastern University, the interface uses an array of copper electrodes to sense a certain change in the electric field created by the device. The black material covering the electrodes shows how the interface can be hidden beneath surfaces to create a completely invisible interface. It is simple black felt you can buy at any fabric store. The total cost of this prototype was around $60.00 USD.They created custom software to communicate with the microcontroller running the show with C++. This enables the use of the device as a new type of XYZ computer mouse. Think nintendo…

Augmented Reality Magic…..or simply MAGIC!!!

"Augmented Reality", Computer Vision, Technology, Video
Came across this video today and my first thought was.....magic??....Hmmm.....gotta be a video editing trickbut once I watched it for the fourth time it slowly started to click. This is by far the most innovative use of AR I've seen.....It's fascinating.....It's Magic :-). Watch Marco Tempest do his thing in this warned might have to watch it a couple of's addictive. Lots of behind the scenes pictures here.BTW. Marco writes:    this is 100% real-time stuff - No post-processing. Programmed In C++ with OpenFrameworks, OpenCV, ARToolkitPlus, MacCam and other Open Source goodies…
