I’m glad that I had opportunity to join Startup Camp in Trhový Štěpánov as mentor. Together with startup teams we were discussing and preparing new sites for their products. People were learning how to use Git, how to program in Python and how to create sites in Django. At the end of the day they were able to create prototype or deploy it to Heroku cloud.
Yyou can find my slides at SlideShare or download it as PDF.
Examples of Python code and simple Django testing project are available at GitHub in repository try_git.

You can zoom-in or out text in editor window of IntelliJ idea (PyCharm) by CTRL + Mouse wheel.
The only problem is that this feature is disabled by default. You have to turn it on.
Press CTRL + Alt + S (Settings) and type: “change font size” into text search field. Select: Editor and check option “Change font size (Zoom) with Ctrl+Mouse Wheel”
Deploying Django app to Heroku from Windows machine is little bit tricky.
You can follow instructions in Heroku manual. The first problem that you may encounter is with Postgres support in Python. There is problem with this command:
pip install Django psycopg2 dj-database-url
If you do not have Visual Studio installed on your machine, you’ll receive error that vcvarsall.bat is missing.
Solution is quite easy. You don’t need to install Visaul Studio. Just download binary version of psycopg2 module from http://www.stickpeople.com/projects/python/win-psycopg/
Then you can exclude psycopg2 from pip install command, because it is installed in system directory of Python.
Another tricky issue is with command:
pip freeze >requirements.txt
If you type this command in PowerShell then it will automatically create Unicode file with extra bytes. When you try to deploy project with messed requirements.txt to Herou then you’ll see self explanatory error
TypeError: must be encoded string without NULL bytes, not str
Just open requirements.txt file with notepad and select Save as. In Save as dialog choose ANSI.
Commit file and push project to Heroku. It will work
Update: This article is relevant only for desktop version of Skype for Windows 7.
It’s quite easy to change default font size in Skype, but option is little bit hidden.
Open menu: Tools – Options.
Click: IM & SMS
Choose: IM appearance
Click: Change Font
Change the font and Save it.
Update: I switched from Console2 to ConEmu. ConEmu is far more advanced.
Console2 is great little front-end for Windows. It makes PowerShell even more usable. It’s very flexible and you can configure console window to behave like terminal window on MacOS or Linux. It has also support for transparency. It’s simply great. No need to add any more words. Just try it.
I’d like to add few more hints.
- Go to Settings – Appearance – More…
- Select Window transparency – Alpha
- Change alpha level of Active and Inacative window.
Copy on left mouse button click, paste on middle button click
Default configuration of mouse is not very useful. You have to press Shift and Left Mouse to select and copy text. Make small adjustment:
- Settings – Hotkeys – Mouse
- Change: Copy/clear selection to Left + Shift
- Change: Select text to Left
Use Console2 as front-end for NodeJS
You can use Console2 to invoke also NodeJS shell. Just create Tab definition for NodeJS.
- Go to Settings – Tabs
- Add NodeJS and set Shell to: “C:\Program Files (x86)\nodejs\node.exe”
Create new Tab with NodeJS profile:
