For a Django application, deployed on Heroku, what are my options for storing user-uploaded media files?
S3 is really a no-brainer for this, it’s extremely inexpensive, very easy to integrate with and unbelievably reliable. It’s so cheap that it will be practically free for testing purposes (expect to spend pennies a month on it).[... 88 words]
Build something and put it on the internet. Make sure you have an easy way to deploy new versions (Heroku is a good bet if you don’t want to figure out Fabric). Pick a project that’s useful to you—a simple blogging engine is often a good bet, or maybe something that aggregates together your posts from Twitter and Instagram and so on. Or come up with something a bit more creative![... 109 words]
How can some really large services (like Dropbox) afford to use Python as a primary language, if it’s one to two orders of magnitude slower than other, compiled languages?
Because raw language speed often doesn’t matter that much. In the case if Dropbox the client software spends most of its time waiting for bits to load from the network or from disk. Most large websites spend their time waiting for the database. You can’t speed up network or disk performance by using a faster language.[... 91 words]
The best way to learn python in my opinion is using the interactive prompt. Install ipython (a massive improvement on the standard python shell) and use it to interactively solve some simple tasks—things like downloading a CSV file from the web using the urllib library, parsing it with the csv module, then poking around in the data using python list comprehensions and saving some of the results out to a JSON file.[... 95 words]

What are the tradeoffs (e.g. development speed, performance, scalability) between using various php frameworks, ruby/rails, or python/django? Is there any reason to choose one overwhelmingly over another?
At this point, I’d argue that the decision between them comes down to programming language rather than framework—the frameworks have mostly converged on a very similar set of features.[... 145 words]
