Today i worked With WtContainerWidget , Wimage and Wtext and made a program to know how to use these widgets of Wt. It was a day full of presentations . Firstly there was a Presentation On debian packages by Gurpinder. It was quite an informative and interesting Presentation and then there was another Presentation on Backup By Ishpuneet . He told us about Different types of backup techniques and a backup tool called Bacula . Then After that Gagan gave a Presentation on BRL-CAD and there was a pretty interactive discussion on laws of reflectiona and refraction of light .
