Showmedo is a peer-produced video-tutorials and screencasts site for free and open-source software - with the exception of some club videos, the large majority are free to watch and download.

Educating the Open-source Community With Showmedo

Although as important as the software it supports, education and documentation are relatively neglected in the Open-source world. Coders love to code, and explaining how best to use or improve the software tends to be deferred or even sidelined.

At Showmedo we believe the community can play a vital role here and also say thanks for the tools and software that make our lives easier. If you have a piece of software you love or a programming langugage you are enthusiastic about, why not make a screencast showing others how to use it? All the stuff you wish you'd been told, the tips, tricks, insights that would have saved you time and frustration.

Screencasting is easier than you think, and we're happy to help you. You can email us for advice or just use some of the how-to screencasts on the site. This screencasting learning-path is a good place to start.

31. Peter Sun, 24 Jan 2010 10:15

Thanks a lot ! More on unittesting with python would be highly appreciated !

( for example: testing webservers , pylons, testing pyqt stuff, etc, where to stop writing tests ,, )

30. anonymous Thu, 17 Dec 2009 18:56

Once again, really helpful tips!

29. anonymous Tue, 10 Nov 2009 15:59

Thanks. I'll give nose a go.

28. anonymous Wed, 21 Oct 2009 07:31

I have done unit testing code coverage in PERL and other languages. I am new to Python. Your example here was excellent.

Thanks,

David McAllister

27. anonymous Mon, 12 Oct 2009 03:58

thanks, useful, epecially the coverage bit

26. anonymous Fri, 02 Oct 2009 13:39

Clear intro to nostest. Very helpful. Thanks.

25. anonymous Thu, 01 Oct 2009 09:04

video 2 and 3 not working for me.

Do they work for others??

24. anonymous Wed, 23 Sep 2009 09:51

very informative ....

23. anonymous Thu, 13 Aug 2009 05:32

Very good job! I'll be using this package in the future!

22. anonymous Wed, 05 Aug 2009 02:39

Nice demo.

21. anonymous Tue, 28 Jul 2009 09:33

Thanks Chris for the videos on nosetests and sphinx/rst! I particularly like knowing about doctest. Just seeing a few of these in "action" helped me get a little further down the line.

20. anonymous Tue, 14 Jul 2009 09:15

Thanks for the video on nosetests. I'm starting to wade into the world of TDD, and this was a helpful tutorial.

19. anonymous Thu, 09 Jul 2009 01:16

Thanks for making the video. I was getting ready to work with coverage for the first time and your video was an excellent tutorial on what ot expect. The @raises decorator part was an unexpected learning. That alone should save me some time. Thanks again, Chris

18. anonymous Thu, 18 Jun 2009 00:15

Thanks a lot!

It was helpful for me.

I think visual quality and volume was enough.

Good job.

17. anonymous Wed, 17 Jun 2009 00:07

It was useful, I was struck up with nose, i think this screencast will give me a move on. Thanks.

16. anonymous Thu, 14 May 2009 14:54

Very helpful !

note: "o' in VI might save you some time if you still add line the way you did in this screencast.

15. anonymous Wed, 06 May 2009 11:58

Thanks for the tutorial. I was actually trying to find how the hell should I use the 'coverage' plugin (which was fixed by doing easy_install coverage... duh!)

You helped out in getting some of my frustration out of the way.

Thanks again!

14. anonymous Wed, 06 May 2009 10:16

great job.... ;)

13. anonymous Wed, 06 May 2009 10:16

great job.... ;)

12. anonymous Wed, 25 Mar 2009 17:23

thanks!

11. anonymous Thu, 20 Nov 2008 18:37

it would be nice to have a transcript and/or the source code somewhere. I used the TG2 tutorial

to run similar tests, with "nose" and "coverage".

thanks!

Review of Using Nosetests and Coverage to create robust software

Even with a high-quality monitor, I could not read the text.

A text document with all of the commands you typed in would have been helpful.

8. anonymous Wed, 16 Jul 2008 16:44

Thank you for the introduction to nose/coverage!

Review of Using Nosetests and Coverage to create robust software

Awesome production, and the python script looks nice. I still would want to have a more instructional workflow, like try to number the workflow. Sometimes since it is a terminal is hard to know where to focus the attention.

Also would be nice to have let say a label explaining what are you trying to do. But is great production.

6. gasto Wed, 09 Jul 2008 22:05

More screencasts please...

Review of Using Nosetests and Coverage to create robust software

Awesome stuff...pls bring more :o)

4. Ian Ozsvald Mon, 07 Jul 2008 11:07

Great screencast. It is good to see more time given to testing, I show nosetests a lot in my Club videos (I think TDD is darn important!).

It is cool to see you use coverage too, I remember the first time I tried it on the ShowMeDo codebase...boy did that take a good few minutes to run and report :-)

Your style (video, zoom etc) is good, that's a nice change to the usual style where you just see the sw in action (my normal style!).

Cheers,

Ian.

3. Kyran Dale Mon, 07 Jul 2008 11:00

wow - fireworks have got to be the screencasters ultimate nightmare - you handled them admirably. With me it's the screaming seagulls fighting outside my window. Another nice screencast - we use nosetests with showmedo but coverage is new to me and looks like a terrific extension. Ta again.

DrC 42 days ago

Using Virtualenv and PasteScript

Great, crisp, succinct delivery.

I came across this link to your demo while trying to find info on how to use virtualenv to enable the use of more than one python version on a system. ie. Current Ubuntu and Fedora systems come with python 2.6.xx . But I want to experiment with Zope (Zope 3) which seems to like python 2.5 better. As a very new programmer, I am realizing I am probably jacking up libraries that Fedora needs to function properly by installing every web application framework out there willy-nilly. Probably why my former Ubuntu install got so ginchy.

Would you consider demoing the proper way for a new programmer like me to set up a sandbox with virtualenv - and perhaps even how best to tear it back down once one is finished playing with a library/alternative python version. (another example being creating a sandbox to play around with Python 3.)

Once again - Thanks for sharing your skill!

Very useful, since the online doc on paster is rather complicated and I found it difficult to understand how paster can be used the simple way. Any in-depth discussion on packaging , paster ,etc would be of much interest.

Thanks
