Description
IT Lightning Talks (ITLT) are short presentations on any topic related to computing technology or to the IT department. See more here: https://twiki.cern.ch/IT/LightningTalks/
Open source is the right to modify, not the right to contribute. Are external contributions absent from your project? Have you ever thought about what is it like to be a new contributor on your project? I challenge you to transform your project from Open Source to an Open Collaboration.

Raspbuggy, a programmable WiFi model car8m31/3-004 - IT Amphitheatre
Representing complex data visually is an important tool for communication, and the CERN Knowledge Transfer Annual Report is no exception to this. I want to share with the audience our experience with data visualization through the strength of collaboration, and the power and simplicity of the d3.js javascript framework.

Maybe it's not Python that sucks, maybe it's my code8m31/3-004 - IT Amphitheatre
Did you know that in Python integers from -5 to 257 are preallocated? Reusing them 1000 times, instead of allocating memory for a bigger integer, saves a whopping 1 millisecond of code's execution time! Isn't that thrilling? Well, before you get that crazy, learn some basic performance tricks that you can start using today.

So what is this application really doing? - debugging with strace(8)8m31/3-004 - IT Amphitheatre
Have you ever wondered what your program does under the covers? When does it open network sockets, which configuration files reads or... why suddenly stops responding? In this talk we will refresh some OS knowledge and learn how to eavesdrop syscalls with standard Linux tools.

Networking made easy - there must be an app for that!8m31/3-004 - IT Amphitheatre
We've changed the way we work – remotely, by video conference, in worldwide collaborations. We've changed the way we share ideas – through events like IT Lightning Talks and TEDx. How can we change the way we network? A call for volunteers to develop networking activities for TEDxCERN 2015.
