Since 2003, I have been conducting corporate training programs on various subjects like Qt, OpenGL, VTK, GCF. At one point I was even teaching Linux Kernel and Device Driver Programming, thanks to my employment at Linux Learning Centre.
Over the past 13 years, I have been able to observe certain meta-data about the training that I personally offer and also the training that I have attended as a participant.
Today XML and JSON are hot formats for data exchange. While Qt natively supports XML, it doesnt support JSON (well directly). Most developers use external libraries like qjson to serialize QVariantMap objects to a json-string and parse json-string into QVariantMap. One of the key disadvantages of using qjson (or maybe even other libraries) is the license. qjson for example is a LGPL library, which means using it in mobile phone apps might not be a good idea, where the general interest is to not have external dependencies. So the question is – “is it possible to have a JSON serializer/parser using Qt only – without too much of an effort“. The answer is YES! Continue reading “Simple JSON Parser / Serializer in Qt”
I have been reading this book called Tell-a-tale Brain from V. S. Ramachandran. I must say that his books are just as pleasing to read as it is to listening to his talks. The book brings together the author’s findings from several years of research about the human brain. With interesting tales, research findings and personal opinions – VSR takes the reader on a nice tour of the human brain. I bought the book after listening to his talks on TED. I read the book from cover to cover as quickly as possible when I read it for the first time. The idea was to get a really quick gist of it. I am reading over it in more detail for the second time around now and I am sure I will read it again and again in the years to come. With every read, the mystery of the brain deepens and it is quite thrilling to know about one’s own brain. Continue reading “Machinery of the “Brain””
