Recently I upgraded my KDE version 4.2 to the 4.3 and I’ve been using it for a few days now. As said before I don’t mind using betas and do some testing, but as with everything there is an exception, in my case it was KDE, I used the first KDE4 betas and come back to 3.5 then used the 4.1 when it was stable, then 4.2 and tried the beta 4.3… once again came back to the 4.2, now that is stable I’m using version 4.3, and for the first time in KDE4 I can say it’s stable. In my opinion KDE4 was released way to early, and although usable it was needing serious work around it. I’m a Linux user with several years of experience and didn’t have much trouble using it, but for instance my wife would go crazy, so till KDE4.3 she was using KDE3.5.
What changed in this last version of KDE that made me upgrade all my machines to KDE4.3?
The KDE community has fixed over 10,000 bugs.
Implemented almost 2,000 feature requests in the last 6 months.
Close to 63,000 changes were checked in by a little under 700 contributors.
If you want to read more about it just check this link.
All this made KDE4.3 more user friendly, more reliable, more polished and prettier.
So, what more can I say about it? JUST INSTALL IT AND GIVE A TRY you won’t be disappointed.
In conclusion is there innovation or just patching in KDE 4.3? Definitely both, there’s hundreds of new features and even more bug fixes. Both are equally important and KDE really need this ultimate push to be the ultimate Desktop Manger.
Cheers and see you next time
ps – bellow there are the install instructions and a vid of kde4.3 in action.
If you need help to install it just check the install instructions (from www.kde.org):

QOS – “Quality of service” – what a fancy name for somethings that will allow you to manage the available bandwidth for your servers/pcs/equipments. Usually setting up QOS is not “so fancy” to setup and manage. At work I had to setup a QOS for a custumer and didn’t want to be writing rules on my own so I searched a bit and found MasterShaper.
You can read more about it here.
Lets imagine that you want to allow p2p on your network but you don’t want to waste all your bandwidth on that kind of traffic, after all you still need bandwidth for your VOIP, http, and mail traffic.
To setup this I’ll be using CentOS and Mastershaper.
After installing a VMware virtual machine with CentOS (default install with 2 network cards), I’ve setup apache, this time I didn’t use virtualhosts or any other extras as I just wanted to create a single purpose system.
To start I’ve concufigured 2 network interfaces (internal/external)
eth0 192.168.251.249 (external)
eth1 192.168.252.249 (internal)
After downloading MasterShaper decompress it to:
Install pear and pear modules as described in MasterShapper docs.
And finally create the mysql database to support the installation.
I won’t get into install details (just follow the documentation), but in the end you be able to define schedulers, hosts and services with higher or lower priority and in the end you’ll also be able to monitor all this in a pretty web interface with some graphics.
Just don’t forget to install mysql support in php, and pear, you’ll also have to configure sudo but in the end just read the documentation in mastershaper it’s very good.
This weekend I was updating and reconfiguring my apache2 installation, I run a server with multiple domains both with http and https, they are sitting behind a firewall. I also had some tomcat installations running on port 8080 on my server. In my previous configuration in the firewall I had port 80,443 and 8080 forwarded to my apache server and it worked perfectly. but as you know it’s easy to educate users to use both http(port 80) and https(port443) but not that easy to tell them to write https://yourserver:8080/blabla to redirect them to the tomcat server.
Having this I decided to change the way things work but using a reverse proxy this way I can have all the users using just http and https and at the same time redirect the traffic to the t0mcat behind the the firewall.
How did I do it?
First you have to enable the following modules on your apache2 server (I won’t explain how to do it as you can do it multiple ways and even use your distro tools to help you):
I also recommend you to use virtualhosts for doing this as you’ll be able to serve multiple domains with ease:
