Somebody forward this story to me.. I thought it was amusing.. —— Once upon a time the government with Ruling Party XYZ.. had a vast scrap yard in the middle of a desert. Ruling Party XYZ Said.. – “Someone may steal from it at night.” So they created a night watchman position and hired a…

BiBox is a product from a startup-company, founded by one of my friends from JNNCE Shimoga. It targets the education sector, which in my opinion is a very huge market. It allows kids to visually design electronic gadgets and bring them to life. Youcan visually create things like moving trucks, bulb-array displays etc.. The killer…

I am at IIT-Mumbai right now attending the Techfest. This year, among several parallel tracks, they have arranged for a Haptics track. Manav, a MTech student, who is organizing the track contacted us about a month ago asking us if we were interested to sponser and/or speak at the event. I thought it was a…

http://www.qtsoftware.com/about/licensing/a-letter-to-our-customershttp://www.qtsoftware.com/about/news/lgpl-license-option-added-to-qt It would be a good move if KDE decided to adopt the LGPL version of Qt 4.5 instead of the GPL one. That way people would be able to develop both closed and open-source software for Qt without having to buy Qt licenses. I think I will still renew my license, because QtSoftware support…

I have been hearing about this for the past couple of weeks. It seems Qt will become free even for commercial developers. We actually held back our License Renewal POs after sensing that the rumors were very strong. Apparently Qt Software will make an important announcement on the 15th of January. So, until then we…

Problem: How to profile functions in my Qt app without using gprof or spending big bucks and buying profiling tools for VS2005? Solution: Have the following contents in a header file, Profiler.h for example. #include <QTime> class FunctionProfiler { public: FunctionProfiler(const QString& func) { m_function = QMetaObject::normalizedSignature( qPrintable(func) ); m_function = m_function.remove(“__thiscall”); m_function = m_function.remove(“__stdcall”);…

Looking more closely at the look and feel, I thought we should ensure that a) the width of the menu-strip group should be same as that of the drawer when open.b) there should be some visual cue for a user to find out which group has a drawer and which one doesnt Thats exactly what…

A couple of weeks back I got this strange idea for MenuStrip-GCF based UI. I tried it out and tested the results on VTK Designer; to be honest I like it. MenuStrip-GCF based apps try to keep the number of QActions on the window to a minimum. But sometimes, it might be necessary to provide…

I am right now in the last half of the last day of a course on C++ Internals conducted by Collosal Learning’s Mubarak. The workshop is really interesting; a must attend for anyone interested in becoming a really good C++ developer. The “internals” knowledge of C++ is something you would gather if you have worked…

FOSS.IN 2008 was about changed focus “show me the code”. I was at the opening ceremony today, I got to say that Atul was very clear about what to get from this edition of the event. But to be honest, his speech could have been more planned and powerful. It lacked the punch. While the…

The last three weeks were very interesting. The whole wedding, reception, honeymoon and then getting back home and setting it up for post-marital life was both fun and exhausting. Overall I am happy with all the changes, it is a lot less scary than what I had thought it would be. Anyways, before moving ahead;…

Over the past few months we have been working with KDAB, the world’s leading Qt company. During FOSS.IN 2007, I got a chance to meet Till Adam of KDAB. We discussed at length about GCF and how to go about productizing it. After that meet a lot of interesting things happened and after a lot…

Starting from today the wedding events begin. 🙂 The events start from today all the way until Sunday, the 9th of Nov. The actual wedding happens on the 6th of November, but until then we have a bunch of poojas. It ends with a small-and-concise reception in Bangalore on the 9th.
