GIMP tutorial - short one... but very good ...

found on youtube http://www.youtube.com/watch?v=hbFVFrEYXjk

kde and qt development with c++

Well a lot of blogs start about hello world !!! but what about people who have just installed kubuntu and what to do devlopment ?


Here is what you need
1. A development IDE you are comfortable with
for emacs - sudo apt-get install emacs
you can use vi or kate they also work great.
There is KDevelop which is much better ! install using sudo apt-get install kdevelop

2. Libraries
sudo apt-get install kdevelop kdelibs kdebase-workspace-dev build-essential cmake


Now go grab the QT hello world !


Python development on Kubuntu or Ubuntu with emacs !

Here is what you have to do
1. Get the python mode files from https://launchpad.net/python-mode , it is a gz file with 4 files and 1 readme in it.
2. unzip that and put the files in your home folder (~/)
3. Now create a file .emacs in your home folder (if you have it already its fine). Add this to the file
----
(load "~/python-mode.el")
;;python
(setq auto-mode-alist (cons '("\\.py$" . python-mode) auto-mode-alist))
(setq interpreter-mode-alist (cons '("python" . python-mode)
interpreter-mode-alist))
(autoload 'python-mode "python-mode" "Python editing mode." t)

(global-font-lock-mode t)
(font-lock-mode +1)
----
4. Now restart emacs.
5. Write python code and then C-c C-c for executing it .. C-c ! for the shell ..

Have fun !

Languages !

Gosh ! why are there so many languages ! Personally I feel the world can do everything with just c. All these new languages are interesting ... but to me as long as there is c++ and java, everything else is just for hobbyists !
Python is getting traction because of google .. otherwise there are so many languages out there ...
I used to work on python in 2001, now ... well should i try it out again ? Maybe !

Netbeans & ubuntu 11.04 with KDE

Well i am always amazed at how great netbeans has got to become ! Its certainly a pleasure , it has been working efficiently for the small things i have been doing , i am officially supposed to use eclipse as we have the .project and .classpath files, though i guess its time .. i try netbeans for official work too ! But ah .. there are so many things. ..

Jdk 7 beta released ! awesome ... well done ...

Well tired of unity - somehow i feel compiz has become a beast ! , i am not finding kwin to be better ! am on KDE at home ... (kubuntu .. thought ubuntu treats everything else other than unity .. badly), but KDE has been working fine ... No hangs etc !

canonical launchpad !

launchpad is an awesome platform .. it enables development , collaboration, bug reporting etc ... its an awesome collaboration platform , however small quirks

If you unsubscribe a bug by mistake, there is no way to resubscribe to the bug, even if you had raised the bug .. solution wait for the LOSA's to reenable it for you !

Firstly if I have raised a bug, there should be no way to unsubscribe from the bug, obvioulsy because i raised it .. i would want to know the status, otherwise why would i raise it in the first place. Even if i have to unsubscribe, most likely in cases where i raised the bug on behalf of someone, it should warn me and force me to give the name of some other person on my behalf who will represent the bug owner !

Strange, small issues ..

ubuntu 11.04 fresh beta - installing skype 2.2 beta

Well here you go .. after a long time skype has finally released an update of its software for linux !! thanks skype finally ...

To install in general you need to first make sure you have th dependencies .. First download the deb from skype website
1. Try this
$ sudo dpkg -i skype-ubuntu_2.2.0.25-1_i386.deb
I got some error at the end ...

So i did this
$ sudo apt-get install -f
This resolves all the missing packages and installs them for you.

Now repeat
$ sudo dpkg -i skype-ubuntu_2.2.0.25-1_i386.deb

It will be successful !

Gnome3 and Fedora 15 rawhide

Alright , i am on fedora now ! Do i like it .. definitely, i havent seen a crash for the past 2 days i have been using, it is pretty stable. The only issue i have is with gnome 3 usablity. It is pretty stable and looks great, but it has left out a lot of customizations that a user used to have ..
Some of them
1. Cannot change themes (Nothing at all) except background wallpaper.
2. I dont think i like the notifications system, it just pops up and then dies down .. until we go and put our mouse in the bottom right corner .. that is bad design ... as there are times i am not in front of my computer and when i come back , i am not sure if there are notifications, so i have to go and see .. and that is repeated every 2-3 mins .. it is important to leave the decision to end user !
3. Still seeing how to activate screen saver ...

More updates soon, the only thing i really like is the stability ... it is sort of crash free ... touch wood !
