Nagpur PHP Meetup – Report – August 2009

August 8th, 2009 4 comments

The second PHP meetup in as many months was held today, 8th August 2009. Unlike last meetup where mostly freshers attended it, this time was saw only experienced PHP programmers in city for the meetup. Reason – the topic of meetup. It was to discuss the security issues faced by developers while writing commercial as well as opensource programs.

The meetup started with my seminar on this topic where I tried to cover the basic problems, general programming flaws which leads to various security vulnerabilities. The major topics covered where –

  • Input validation
  • Cross Site Scripting, i.e.,  XSS
  • SQL Injection and
  • Session Fixation

The seminar was followed by some useful tips from Dr. Tarique Sani on how to write the secure code. He pointed out that code security should be implemented from the point you begin the project. It shouldn’t come as an afterthought as it becomes impossible to make your application 100% secure at a later stage.

We also discussed some community building exercises to get more PHP developers from Nagpur for the meetup. Everyone at the meetup agreed to bring with them atleast two more PHP programmers for the next meetup who are either their colleagues or their friends working in other companies in Nagpur.

The agenda for next meetup was also fixed. We will be targeting the newbie crowd who atleast knows what is PHP and will guide them on How and Why do PHP. Also, those who will bring their laptops/netbooks/PC’s at the meetup, we will help them install and run PHP on their setup.

Finally, a big news – We have booked the venue, Jog House, for every second Saturday for next 12 months (except November and December when it will be on first Saturday).

I hope all my friends working on PHP in Nagpur will see this post and start attending the future meetups.

Changing default browser in Kubuntu

August 6th, 2009 6 comments

Yes, I am writing a blog post for a task that sounds very simple to achieve – just with a click of a button. But this is not true, atleast  with Kubuntu 9.04. If  you are coming to this post through search engine then you have already gone through this pain. If not, give it a try 😉

Surprisingly, the browser’s functionality of setting it as default doesn’t work in Kubuntu. At the same time, changing it manually from System Settings -> Default Applications doesn’t seem to work either.

To set one of your browser as default browser, you have to run the command

$ sudo update-alternatives --config x-www-browser

You will see the list of browsers currently available in your system and then you will enter the number for the browser you want to set as default. My console with 3 browsers was something like follows

$ sudo update-alternatives --config x-www-browser

There are 3 alternatives which provide `x-www-browser'.

Selection    Alternative
-----------------------------------------------
+        1    /usr/bin/konqueror
2    /usr/bin/firefox-3.0
*         3    /usr/bin/google-chrome

Press enter to keep the default[*], or type selection number:

That is it. Enter the number for the browser you like and hit ENTER. You have your browser set as default.
