At pgday there was this form you could fill to give speakers some feedback about their talks. And that’s a really nice way as a speaker to know what to improve. And as Magnus was searching a nice looking chart facility in python and I spoke about matplotlib, it felt like having to publish something.
Here is my try at some nice graphics. Well I’ll let you decide how nice the result is:
If you want to see the little python script I used, here it is: feedback.py, with the data embedded and all…
Now, how to read it? Well, the darker the color the better the score. For
example I had
5 people score me
Topic Importance on the Hi-Media talk
(in french) and only
3 people at this same score and topic for
talk. The scores are from
5 being the best.
The comitee accepted interesting enough topics and it seems I managed to
deliver acceptable content from there. Not very good content, because
reading the comments I missed some nice birds-eye pictures to help the
audience get into the subject. As I’m unable to draw (with or without a
mouse) I plan to fix this in latter talks by using
Through Ascii Art tool. I already used it and together with
picture-mode it’s very nice.
Oh yes the baseline of this post is that there will be later talks. I seem to be liking those and the audience feedback this time is saying that it’s not too bad for them. See you soon :)
I have added the
feedback.py script now that each page here is published
