Removing my feed from planet KDE

kd — Sun, 12 Jul 2009 17:41:31 +0000

As I write about many things (which includes all my PyKDE or PyQt apps) some people are seem to be very much offended to read them in Planet KDE.

So, I am just removing my feed to make the planet junk free.

Though I used to get highest number of hits on my screenshots and photos in flickr from planetkde.org :)

Pony v0.2 released

kd — Wed, 03 Jun 2009 12:14:19 +0000

I just released Pony v0.2 . It is still under constant development and will go some db changes before v1 release. Please delete .pony.db under your home before using the new release.

$rm ~/.pony.db

Among new features one can now see the EXIF information of an image.

Deleting tag option is also added.

Get the source or rpms from here.

Now I have to add TODO file as too many things need to be fixed. If you have any suggestions please mail me or file a ticket.

NetworkManager issue with ad-hoc connections

kd — Mon, 27 Apr 2009 05:49:57 +0000

I am using a mobile broadband device and created a ad-hoc connection in NM to share it. The device works out of the box and ad-hoc connection also works very fine.
But some times if I disconnect from the broadband device, NerworkManager crashes, and after restart when I start that ad-hoc connection once again, it automatically creates too many ad-hoc connections with strange names and the list continues to grow.

You can find the bug here. I am on rawhide.

pyexiv2 problem in rawhide

kd — Thu, 16 Apr 2009 10:09:27 +0000

pyexiv2 is the python extension of Exiv2 library. It helps to find the EXIF information from an image.

The current rawhide version is broken, it just can not be imported.

[kdas@d80 ~]$ python
Python 2.6 (r26:66714, Mar 17 2009, 11:44:21)
[GCC 4.4.0 20090313 (Red Hat 4.4.0-0.26)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import pyexiv2
Traceback (most recent call last):
  File "", line 1, in 
  File "/usr/lib/python2.6/site-packages/pyexiv2.py", line 60, in 
    import libexiv2python
ImportError: /usr/lib/python2.6/site-packages/libexiv2python.so: undefined

Tried to find what that symbol is using c++filt

[kdas@d80 ~]$ c++filt _ZNK5Exiv29Exifdatum6typeIdEv
Exiv2::Exifdatum::typeId() const

Now is this a very new pyexiv2 which contains symbols from latest exiv2-lib or a problem itself ? The bug is here.

Update: It seems to be a local symbol. It comes from exiv2-lib only , but it shows as local with “notype” from the eu-readelf output :(

Laptop is not booting up

kd — Thu, 09 Apr 2009 05:51:41 +0000

From today morning my Dell Latitude D630 is not booting. Called service center , the guy asked me to press different kind of key combos for troubleshoot. Then he asaked me to open the keyboard which is a real bad idea as I can damage the system. After a big argument on this finally they agreed to send an engineer with required parts.

Asking a user to work/open the hardware is not at all a good practice, don’t know why they keep asking the same.

Meanwhile view this (less than 1MB), I hope that code is safe in my broken box :)

OLPC Pune meet and photo management

kd — Mon, 06 Apr 2009 05:28:22 +0000

This Sunday I went to OLPC Pune meet to give a talk on activity development. The students seem be very enthusiastic. The talk lasted for around 2 hours. Photos can be found here.

On the other side, I was looking for a photo catalogue software which can catalogue my photos on DVD or any other removable media, it should also allow me to search them based on EXIF data and tags and should show thumbnail(s) in the result.
I generally use digikam and gthumb too manage and view the photos. In digikam I never being properly able to catalogue photos on DVD (never tried on the last few updates) and gthumb is too slow in showing the thumbnail or full screen views for the large size photos I take. I prefer gthumb over over digikam to view the photos due to the simpler UI.

Finally decided to write my own app for this, which will *not* have any editing features, Gimp is the tool I use for editing. Watch this video (3.2MB) and please comment if the thumbnail creation / viewing is fast or not ?

How one can start learning PyKDE ?

kd — Wed, 01 Apr 2009 06:26:00 +0000

Dear lazyweb,

How one can start learning PyKDE ? For PyQt , reading a few very basic examples given with the source and then reading Qt-help docs seems to be fine. But the KDE libs are much bigger, though one can find a suitable class to work with, how to use that is still not so easy for a newbie.

When it comes to the GUI, it is again not clear to me that which approach one should take , design everything in code ? or one can use qt-designer for that.

Summer training 2009

kd — Sun, 29 Mar 2009 16:07:43 +0000

You can find the wiki page here. This year we want to make groups such that there are two students in a group and make them work on any upstream project or a new project. They should start the work of finding the project ideas within first two weeks of the program. Comments/suggestions are welcome.

We have added a few buzz words in the poster to attract students. Generally students prefer to go to different small institutions to do summer project where most of the times they pay a good amount to get a certificate. Trying to change the situation slowly.

Thanks to Nicu for the poster.
