Yep, its April fools day. According to the headlines the Google homepage just crashed (see to believe), Ubuntu is going to become an RPM distro and several other stupid newsstories that only prove that you are a complete idiot if you believe them. So I'm not even going to bother with telling you that I just got an official MCSE-certification and am going to accept a position in Belgiums top Microsoft board of executives in a project to kill open source once and for all... nothing of the sorts !

I am however going to point you to a nice tool a friend of mine pointed me towards : EXT2 IFS for windows ! 

So here is the situation. you are running a dual boot scenario with both Windows and Linux on the same system. You would like to have your "documents" available in 'both' operating systems. Not just your "my documents" in Windows and your "home folder" in Linux. Well , its not very hard to do. The first alternative that you have is to have Ubuntu read the NTFS partition of your Windows XP machine (don't work with Vista)  To do so go HERE. The downside is that this is not a very "fast" way to work. File-access is not very speedy and thats because they need to 'reverse engineer' the closed source standard of NTFS in order to get it working. Sure you can mount your NTFS partition in Linux , but why would you ? 

The other alternative is to store all your data on your "linux system" and enable WINDOWS to read the Linux file format . you'll need to install the tool called EXT2 IFS for windwows and this will let you read and write to your Ubuntu partition (download it HERE ) Once installed the program will ask you to assign a drive letter to the EXT2 partition of your Linux system and TADAAA , you'll be able to access the files.  

The next step is easy, Go to your mounted linux partion and look for the folder called /home/your-user-name ,  Next create a folder in there called "my documents" and remap your my documents folder to this very folder. This will transfer your data from your Windows system to your Linux system. That way you'll be able to access your data using your 'my documents' shortcut on the desktop in Windows AND by going to the "my documents" folder in your homefolder when you are working in Linux.

Its THAT simple and it ain't no April fools joke. 

 
Command line applications : Using Centerim to Chat. PDF

Friday, 27 February 2009 02:37
With the ' Installing your own Ubuntu Server" series running on KWTV I have gotten several questions about "what can you USE that SSH connection (featured in episode II) for ?" Today i'll give you a little explenation of one of the applications i'm running with a simple command line interface (like for example putty) over such an SSH connection. In short : What application do i use using the command line either locally on my server , or remotely connecting using the SSH connection.

Centerim : Chat using the command line.
One of the applications I want to feature today is CENTERIM. Centerim is, in short, a command line based version of Pidgin, a multi protocol chat client. In short , CENTERIM can connect to ICQ, MSN, Jabber (googletalk) and AIM talk. The interface is very simple to use (your contacts on the left, your chat window on the right) and you can sort your contact according to protocol or online status. You can send and receive messages (duh) send and recieve files etc. In short , everything you can do using Pidgin or MSN Messenger minus the heavy graphics and annoying flash animations.

Why should I use it.
Well first of all, chatting via the command line is just fracking cool ! If you are a self respecting geek its uber-cool to swap in that graphical chat like Msn Messger for a black and white terminal screen that gives you the same possibilities. If you are running Linux (for example on your netbook) you can install Centerim and run it in a command line window. That way you save processor cycles and screen space. The OTHER option is that you install Centerim on your home server (or wherever you have it running) and connect from wherever you are using your SSH tunnel. For example : Firewall at work blocking Msn and stuff ? No matter. Install centerim at home, connect in via putty and run it from there. Your traffic is tunneled and encrypted all the way.

How do I install it.
Installation is dirt simple. If you are using ubuntu just go to the command line and type ' sudo apt-get install centerim.

Ok, now what.
After installation type 'centerim' in the command line to start the application. The first time you'll be presented with the configuration screen where you can setup various accounts (your msn account, icq etc) just enter your password and you are good to go. Watch out for the configuration option that says "ENTER SENDS MESSAGE FOR" and make sure to select all the protocols you have configured. ( that way, hitting ENTER at the end of a chat message will send the message, otherwise its SHIFT-ENTER). I have turned OFF showing Offline contacts and enabled contact sorting according to status.

Using Centerim.
Once you have centerim setup you'll find your contacts on the left. To scroll through them press "CTRL V" and use the arrow keys to scroll up and down between them. Once you have selected a contact you want to talk to you can hit ENTER to go to the chat window or M to pull up the contact menu (for extra options). Once you are done chatting to the person hit "CTRL V" again to go back to the list. Hitting G will bring you to the GENERAL menu where you can configure your online / offline status etc, monitor file transfers and configure Centerim. To quit the application hit Q. And that is basically it.

Centerim and googletalk.
If you want to use googletalk on centerim you need to watch out for the 'special' settings googletalk uses. Select the "jabber" account in the "configure accounts" option from the general menu (you get there by hitting G) Make sure you use the following settings.

Server :Talk.google.com:5223
secured: yes
Login : your google account
password : your password
priority : 4


Happy chatting.
And that is about all you have to do to start chatting from the command line.

Sharing Itunes library between two users on the same machine. PDF

Friday, 20 February 2009 05:15

Some problems have the simplest solutions, some are unsolvable.  And some problems seam unsolvable and have the simplest solutions at the same time. One of those problems is the one I have with Itunes in "sharing my music directory" in Itunes on our mac so my wife can access the music on that machine and on other machines in the house. Before I go into great detail i'll describe the setup we have. At our home we have a couple of mac laptops and an Imac. On that Imac we have out entire music collection. (we don't have any cd's anymore) we just play everything from the imac. The itunes library that we have sits under my account. So whenever I am logged in we can access it via Itunes. To make it available to other computers in the house I enabled the Itunes functionality to 'share my library' Thus every time I was logged in other computers in the house running Itunes would be able to access the music. Here comes the problem. Both Nyana and  I use individual user accounts on our macs. Where it used to be a case of 'this is YOUR laptop , this is Mine' its now something like 'this is A laptop and i'll use it under my account". So whenever my wife was home and logged into the Imac she was unable to access the music stored under my user account. It also meant that the library would not be shared out to the other macs when I was not logged in.

So what did we want : We wanted to share out our Itunes library to other macs in the house AND to other accounts on the same machine. Apparently Apple's "all to easy" approach seems a little over-simplified in this case, resulting in a situation that is mega hard to solve. I did some googling and it made matters worse. Apple suggests putting the library in a shared directory, but whenever user A adds something (music, podcasts, ripped files) this is not visible to user B, It would solve part of our problems, but the risk of having a borked up library is something that is very real. The problem is that Itunes stores the music files in a folder, but keeps an index of this file in a different xml file .. FOR EACH USER. So instead of just ONE index file, you have TWO , hence the risk of mismatching music and missing out on things.  Other hacks spoke of scripts, terminal commands and even running a linux machine with Itunes running in whine. Complex stuff !

On my way home in the car I thought of the solution. There is such a thing as 'fast user switching' that allows a SECOND user to log in while the applications and processes of the first user are still running. Why not enable fast user switching, have my account (and the subsequent ITUNES) running in the background as we "fast user switch"' into nyna's account. That way she can log into the Imac and access the music via the shared itunes library (that appears as a network library) and she can access the library when she logs into her mac laptop. So problem solved ! Ok, before 'fast user switching' I terminate as much programs as I can under "my account" leaving only Itunes running. Next up Nyana fast user switches to her account and away we go. When she is done working with the computer she just logs out and I can log back into my own (already running) session.

So we leave my own account running in the background, it eats up SOME system resources, but our state of the art, 4 gig Ram Imac does not realy care about that and we can listen to our music anywhere.

How low can you go. Day one. PDF

The beginning is a delicate time. So says the princess at the beginning of the Dune movie. And some truth can be found in that statement. Yesterday I treaded carefully into a delicate beginning when I went looking for a linux distribution to install on my ten year old Toshiba Satellite for our little "how low can you go" experiment. With only 128 megs of ram, a celeron 366 processor and only a wired network interface, it was kind of challenging to find the right distribution to get started.

I started off with Googling around for a linux Distro that could do the trick. A little googling around brought several possible candidates to the table like DSL (Damn Small Linux) and Puppylinux. I had tried the last one and was pretty pleased with the results some time ago. However its not a .debian based distro, so all the apt-get stuff that makes it so easy to install software on my system would not work. So i went looking for "ubuntu flavored" alternatives.

2 immediately popped to mind being Crunchbang Linux and ELbuntu. The difference with '"standard" ubuntu is that they sport a lighter GUI. Elbuntu uses the E17 gui (famous from the GOS linux version that was hyped last year). After downloading and burning both I came to the conclusion that my system was too light for these light distributions. Crunchbang took ages to boot, Elbuntu took forever to give me its installation screen.

So I thought I would start from the ground up and begin with a Command line version of Ubuntu and choose one of the seperate distro's on top. Hitting F4 at the installation menu of Ubuntu server provided me with 'install a minimal system" and that is what I went for. The installation took most of the evening and when I get home tonight I should have a working (command line only) system to start from. 

So next up its time to choose the GUI and find one that makes the old sattelite a little usable.

With the whole medium of "video" becoming popular and available on the internet, its truly a feast if you need to "explain" how something is done. Sure with the KWTV screencasts we are doing just that, but sometimes you don't realy have to re-invent the fire. Browsing around with MIRO yesterday, i stumbled on this wonderful video on setting up a DYNDNS account and accesing your machine from anywhere, even if you get a dynamic IP address from your ISP. 

This little video is a perfect companion to the KWTV 008 and 009 episodes on setting up your own linux server. So if you are following these episodes, make sure to watch this great episode from these guys from systm on setting up your own DYNDNS account so you can access your server from anywhere. Enjoy.
