A powerpoint .pptx to Latex .tex convertor tool

A colleague of mine is making some very nice Latex-based presentations, including a dynamically generated section-overview on each slide. Since all my current slidedecks are made in Powerpoint I started working on a small tool that converts .pptx to .tex latex files. (make note: this tool won’t work with oldschool .ppt files!)

The tool is far from done. But the basic functionality is there. Currently the tool converts a .pptx file to a  .tex and keeps the following slide information:

  • All titles
  • All text/bulletitems
    • Including identation
  • All section headers
  • Option to include hidden slides
  • All images
    • Each image is extracted and save as a separate file

I’m using the Open XML SDK 2.0 which allows more easy parsing of .pptx using C#. More info on how the tool was made might show up here some day.
Other features that I’d like to include is the ability to export the notes (shouldn’t be a problem) and some simple text formatting information (bit harder).

You can download the sourcecode on github: https://github.com/timdams/Pptx2Tex


“World of C#-craft”: an achievement-based classroom?

In a previous post I already briefly hinted at this: wouldn’t it be cool to integrate popular pc-game mechanics in classroom labs?

What I am proposing in this post is another way of organizing practical program labs for an audience that isn’t necessarily 100% willing to become a good programmer. Teaching C# classes to undergraduates electronics-ict isn’t always easy:

  • The crowd is pretty diverse: some have no programming knowledge at all, others have already written whole VB.NET apps, etc.
  • They aren’t all interested in the programming aspect of the studies but perhaps are more in to the electronics-part. However in the end, they will need to be proficient in both electronics and ICT.
  • They can’t see why toying around with console-based programs is, in my opinion, a necessary evil for first-time programmers.

However, in the end, all if these students have to become proficient programmers, whether they want to or not.

Having tried several approaches I don’t seem to be able to find an all-encompassing way to reach each and every last one of the students. I even tried to incorporate live voting and twitter integration in slides during lectures…an experiment with mixed results. Don’t get me wrong, I’m pretty sure I’m reaching above an average number of students, but still: I want all of them to love to program! I think I’d be a poorly ambitious teacher if my aim wasn’t to try and get a full classroom to become passionate about programming.

The idea that I propose here lingered for quiet sometime in the back of my head. Being a fanatic gamer myself I am always fascinated how simple game mechanics like achievements, quests, constant feedback of the player’s progress and leveling can make any ordinary game more fun and worthwhile to play. Somehow the act of earning things only a select few can reach is strangely addictive. So why not use these game mechanics in programming classes? Could a simple, yet fun and addictive achievement-system that constantly gives feedback to the student on his progress, enabling him to compare his results with others enable a teacher to reach more students? Could students become more motivated to do menial programming tasks (I dare anyone reading this to come up with fun programming tasks for the first few weeks, when the only thing a student knows is how to create variables and write stuff to the screen)? Of course, a small side note here: this system is primarily aimed for the gray zone of students who ‘might become passionate programmers’ but who usually, in classic classrooms, grow a mild hatred towards anything containing things like i++, public static overrive int, etc. Passionate students will enjoy this system as well, but they actually simply like to code, no matter the form they are learning new things…they might even think of this system as redundant.

This post is not about actually making an achievement-system that I propose. I’m merely trying to give the reader an idea of what I think might be an interesting way to organize a classroom and secondly I hope I can enable some people in actively pursuing this topic. I’m certain some of my ideas (that are far from original) can be as easily applied in any practical-oriented classroom in higher education systems.

So yes, this will be a braindump with, I hope, tiny little ideas that can grow in people’s mind. This won’t be a coherent, scientific rambling about how a classroom can be organized…I leave that to the educationists of the world. And perhaps, if I’m bored with the gazillion other programming ideas I have, I might someday write a follow-up where I actually show a real, useable application. Who knows. Read more of this post

5 Cool new things in Office 2010

I’ve been using the new Office 2010 (specifically Excel, Word, Outlook and Powerpoint) for about two weeks now. What follows is a short list, in no particular order, of the new features which make the upgrade worthwhile.
