Run Multiple Python mod_wsgi Websites With Apache On Windows

Yes, this sounds completely crazy, but there is a semi-valid need to do this, unfortunately. However, when you need to run multiple Python websites on Apache on Windows via mod_wsgi, it quickly becomes apparent that using the typical <VirtualHost> configuration options do not work as expected.

When you try to do it with a <VirtualHost> configuration, you will be unable to setup a separate WSGIPythonPath configuration setting per virtual host, as that configuration directive is not allowed within a <VirtualHost> node. Instead, you have a single WSGIPythonPath for your entire Apache instance.

If you determine that a single WSGIPythonPath will not work for each website you are hosting separately, the only solution I have found so far is to setup multiple Apache services, each running on its own IP Address/Port combination. If you are running Apache 2.2 on a 64-bit version of Windows, you can run the following to setup a new Apache service:

"%SystemDrive%\Program Files(x86)\Apache Software Group\Apache 2.2\bin\httpd.exe" -k install -n "Apache 2.2-Secondary" -f "%SystemDrive%\Program Files(x86)\Apache Software Group\Apache 2.2\conf\httpd_secondary.conf"

Once the service is installed properly, you just need to make sure to put your configuration options in httpd_secondary.conf and then start the service, and you now have two separate Apache webservers running two separate mod_wsgi Python websites on the same Windows computer.

Write Software for People, Not Computers

Throughout a normal day, I end up reading a lot of information about current issues in technology, and today is no different. There was a debate raging about whether or not high-level math was required for programmers that was sparked by this article by Sarah Mei Programming is not math. While it is an interesting topic, and, surprisingly, I mostly agree with Sarah on this issue, that is not the most important portion of her post. The important part is instead a quote from Structure and Interpretation of Computer Programs from MIT Press, and is as follows:

Google Code Shutting Down

Google just recently announced that they are going to begin the process of shutting down their Google Code project hosting service. In the blog post announcing that they were shuttering the service, they let it slip that even Google had quit using Google Code for their project hosting, instead transitioning thousands of their projects to GitHub. Google seemingly blames the fact that GitHub and BitBucket handle project hosting better than Google does as the main reason that they are discontinuing the service.

Don't Be a Dunce, Save Your Orders

There are some gotchas that you think that you will always see coming. One such gotcha is the need to save an object to the datastore to persist any changes you may have made to that object.

While it seems like a reasonable concept at the base level, there are times that the need to save an object completely escapes your mind. It seems that for many non-developers, this occurs when they have been working a long time on a file, typically a Microsoft Word document, shortly before their computer blue screens, losing all of their work.
