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 ..

xournal pdf editor

awesome pdf editor (though really like an image editor).

on ubuntu/debian systems
sudo apt-get install xournal

open xournal and then open pdf .. then make changes. Not really like adobe writer .. but we can edit pdf ...

gnome-do is great !!!!

I have been using gnome-do and trust me its the best productivity tool i ever had ... always looking for something similar .. got if for the first time.

If you are on ubuntu ...
sudo apt-get install gnome-do


and read the tutorial (online) and see how powerful it is.

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

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 !

ubuntu 11.04 beta

well, come on .. why does compiz crash so often ! But good, that it restarts, there were times in alpha, i was logging into unity with a wallpaper .. nothing else .. that shows up ! :)

ssh and scp slow to prompt for password ubuntu 10.10

I had my ubuntu very slow in giving me password prompt .. i had a tough time to fix it. But here is the solution - my issue checked via ssh -vv was a delay in gss.

$ sudo vi /etc/ssh/ssh_config

Uncomment or add

GSSAPIAuthentication no

GSSAPIDelegateCredentials no

Thats it ... now run your ssh and scp, they should prompt for password immediately (ssh loads the config from ssh_config). Atleast that was my issue .. people did ask to change sshd_config and restart sshd , but that didnt help, i had to do it in ssh_config.

ZAGG invisibleSHIELD is a scam

Something worth just 1-2 dollars they sell for 25$. It is bad , i ordered two iPhone 4 skins it took 10 days to come to my place . cost me about 52$ and what do i get ? Two motorola droid full body skins ! So i called them .. wait time 40 mins .. yes i was on call for 40 mins . finally i was given an RMA and told to return , but with a tracking method , and well you guessed it right, they said i have to pay for the return shipping .. well crazy , i think it was their fault they should return me the money for shipping too .. I realized they are there to make huge profits thats right .. they are cheats .. AVOID them at all costs. I have ordered from best skins ever which is 7.99$ a piece, lets see how that order goes through.

ubuntu 10.04 good .. but sad due to kernel issues

My dell studio 1555 always has some issue or the other with kernel. 2.6.31 which came with ubuntu 9.10 did not allow me to change brightness .. ACPI bug. Now that it was fixed in 2.6.32 i was happy with lucid alpha's , but later i came to know that when i was resuming my computer from sleep, it was having ACPI thermal was having an issue, so it shows 0 temperatures, hence fan doesnt start, so the computer runs very hot for some time and then dies. Very very bad. Now yes the fix is in 2.6.33 , but hey ubuntu sticks to 2.6.32 and i dont think there is a plan to backport .. well this is the problem with open source development, it is good, but it leads to lot of bugs and noone responsble for anything. ACPI bugs are not acceptable with laptops in play. So the solution !!! Back to windows !!! yay
Or rather i will try the daily kernels and upgrade my kernel.
