ShowMeDo April Update

[This is a re-print of the monthly Update Email that is sent to all of our Members]

The biggest change you might notice right now is that we’ve added a statement-of-purpose to our frontpage:
http://showmedo.com/
which says that ShowMeDo is focusing on Free & Open-Source software.

Here’s a part of it:
“We’re here to help address the need for good documentation and tutorials, the lack of which, we believe, prevents some great software from gaining the popularity it deserves. If you want to contribute, just join-up and submit a video. It’s a great way to give something back.”

You’ll find notes on making and uploading videos at the end of this email. We’d love to see more videos on topics like Inkscape, OpenOffice, Linux, programming and useful applications.

Helping by spreading the word:
You can help in another way too – spreading the word about our videos is just as important as making them. Do you have a favourite topic here? Remember the pain of trying to find the right documentation and just finding it to be all out of date (or maybe to not even exist!)?

If something here would have helped you in the past – why not write a post telling the right people how to find it?

New Subscription Club Videos:
The ShowMeDo Subscription Club keeps growing, now we have 5 series lasting almost 6 hours:
http://showmedo.com/club
covering:
* pyWin32 for Windows COM – (being published this month)
* wxPython for Beginners (made in March)
* Reliable website testing with twill and nosetests (made in March)
* Python Development and IDEs including PyDev and IDLE
* Python 101 – easygui and csv

Both Kyran Dale and John Montgomery will be publishing their first Club series soon. The new topics will include:
* More wxPython (with more advanced controls and sizers)
* Python CGI (the fundamentals of web-programming with just plain Python 2.5)
* Beginner Python

Join the Club to learn more about Python. Club membership can cost just $5 (US) per month, refunds are (of course!) available, we’re happy to answer any questions you have:
http://showmedo.com/club

Conference Call on Thursday:
Every month we have a conference call, a group of us get together to discuss the latest happenings in ShowMeDo and what needs to be done. You are encouraged to join the call (even if just to lurk and listen in). We run the conferences using free VoIP software (gizmo5 on SIP) on the second Thursday of the month in the UK evening.

You’ll find more details in the ShowMeDo author group, we’ll be arranging the details in the next day or so. Keep an eye on this thread for details:
http://groups.google.com/group/showmedo/browse_thread/thread/1d5a47cafda00722

Fabio’s PyDev video is the most popular video of the month:
Last year we ran a series of most-popular-video-of-the-month competitions – whoever was top of the most-popular list at the end of the month:

http://showmedo.com/mostPopular

won a £20 Amazon gift voucher (or something equivalent for those not in the UK). This month Fabio wins – his long-standing PyDev videos have always been high in our listings:
http://groups.google.com/group/showmedo/browse_thread/thread/f427df1c4c37505d

Well done Fabio!

In the ShowMeDo Learners group:
http://groups.google.com/group/showmedo-learners/t/b9fb4c0b2071c8ce
I was happy to announce that we have a long and colourful article in this month’s Python Papers:
http://pythonpapers.org/
(vol 3 issue 1) which discusses some of our better-known Python authors including Siddhi, André, Jeff, Lucas, Horst and Erik. The article also mentions why users should make screencasts to help document open-source – we humbly suggest that you think about giving back to the community by creating screencasts on your own favourite topics.

In the Learners group marlow has posted a link to a nice article on ‘Why use nosetests? To help you work “without any thought!”‘. Anyone who isn’t using unit-tests but wants to know why they should ought to take a look at this!
http://groups.google.com/group/showmedo-learners/browse_thread/thread/8889750ba86841ba

Are you a member of the Learners Group? It is the ideal place to ask questions and share your own knowledge. We urge you to join the group:
http://groups.google.com/group/showmedo-learners

How to add your own screencasts:
Making a screencast is very easy – if you have the software installed you can produce a 5 minute screencast in just 5 minutes. Everything you need to know can be found here:
http://showmedo.com/addVideoInstructions

The basic steps are:
1) Install screencasting software – free on Windows and Linux, shareware on Mac
2) Test your mic (built-in mics and basic headsets work just fine – half our authors use this sort of equipment)
3) Draft a 5 minute demo on paper – pretend you are giving an off-the-cuff demo to a friend
4) Press ‘record’ and start your screencast – you can re-record as many times as you need to
5) Login to ShowMeDo, visit ‘my page’ and ‘add a new video’ – give it 30 minutes to process and then preview the result
6) We’ll publish it within a day (we always preview new material – we don’t want any spam in ShowMeDo like some of those ‘video-sharing sites’…)

If you can give a demo to a friend then you can make a screencast to teach people around the world – you’ll be giving something back to the community and helping to make more people aware of open-source. If you want advice and you’d like to meet our authors just visit our Authors Group (everyone’s very friendly!):
http://groups.google.com/group/showmedo
