Open Source lovin’ for your Server….

Linux, Opensource, OSX, osx Server, Server, Windows
Continuing with our coverage of "Free your Apps", here is how you can free your Server (and workstation) of those expensive (usually useless) so-called Enterprise Applications. BitNami stacks make it incredibly easy to install your favorite open source server software. Application stacks include an open source application and all the dependencies necessary to run it, such as Apache, MySQL and PHP or Ruby. All you need to do is download the Stack, provide a few pieces of information when prompted by the installation wizard, and that's it. By the time you click 'finish', your new application will be ready to run. All stacks have been packaged using BitRock's multiplatform installer.Bitnami Infrastructure stacks are designed for developers and system administrators and provide you a way of installing a LAMP or Ruby…

Stream your Linux/Windows/Mac Desktop as video using VLC

Apple, CLI, Darwin Streaming Server, Linux, Macintosh, Opensource, OSX, Video, VLC, Windows
A buddy of mine (thanks Mike) showed me this today. There is a input Access module in the newer versions of VLC (0.8.6+) called "screen" which makes this possible. To stream your desktop to another machine (ip address: 192.168.1.2 in this case) just use the following command in Linux (sorry command line only):vlc screen:// :screen-fps=30 :screen-caching=100 --sout '#transcode{vcodec=mp4v,vb=4096,acodec=mpga,ab=256,scale=1,width=1280,height=800}:rtp{dst=192.168.1.2,port=1234,access=udp,mux=ts}'or in Windows (slightly different syntax) use this command:vlc screen:// :screen-fps=30 :screen-caching=100 :sout=#transcode{vcodec=mp4v,vb=2048,scale=1,acodec=mpga,ab=192,channels=2}:duplicate{dst=std{access=rtp,mux=ts,dst=192.168.1.1:1234}}This is one massive command, so lets take a look at it in more detail:screen:// is our input module selection (if you just run vlc screen:// you'll see your own screen on the server inside vlc....kinda cool):screen-fps=30 specifies that we want to screengrab at 30 fps (from default 5 fps):screen-caching=100 sets the internal caching to 100ms (from default 300 ms)--sout is…

How to uninstall almost any application in OSX manually

Apple, CLI, Macintosh, OSX, osx Server
Well, you learn something new everyday. Here is what I picked up today....If you ever install an application that came as a OSX package, there is a good chance that the installer has installed files all over your machine. There is also a good chance that the installer has left you a little gift -- a way out if you like -- in /Library/Receipts folder on your mac.You see, if the author/packager has done their job correctly (most do), there is a Bill Of Material (known as a bom file) that is copied onto your system. In the example below I wanted to check the files that got installed on my machine by the MacFUSE installer so here are the commands I issued:Brainiac:/ mayromlou$ cd /Library/Receipts/MacFUSE\ Core.pkg/Contents/Brainiac:Contents mayromlou$ lsArchive.bom Info.plist…

ItunesFS….MacFUSE rocks!!!

Apple, MacFUSE, Macintosh, Opensource, OSX
Okay so hot on the heels of my MacFUSE install, I find iTunesFS which is a FUSE module for iTunes written by Marcus Müller.....YUMMY :-). Now it's a read-only module (ie: it lets you take stuff out of itunes/ipod/iphone storage, but most of the time that's all you want to do anyways. If you want to try it just download the FUSE module from Mulle KybernetiK. Make sure you have the MacFUSE core package installed first.

MacFUSE….ready for primetime?

Apple, MacFUSE, Macintosh, Opensource, OSX, sshfs
I think so, you see I've been waiting for about a year -- since last years Mac World announcement -- to try MacFUSE, but to be honest I've been a bit of a chicken. In my book you rarely, if ever, play around with the filesystem. Specially with ported beta code and all the "uncertainties" of Apple's latest feline.Anyways, today I finally got up the courage and had enough time to try out MacFUSE 1.1.1 (specially compiled for leopard). You can download the required files from the Google Code's download page. For those of you who don't know, FUSE stands for Filesystem in USErland, and it provides a generic interface that lets the operating system see virtually anything as a filesystem. FUSE provides a single interface that filesystem modules use…
