What’s the cheapest or free stack solution to deploy and experiment with a realtime application in 2016?
Heroku have a good free tier, and comprehensive support for deploying both Python and Node.js. If you are mainly interested in realtime I would suggest starting out with Node.js on Heroku. Depending on the complexity of your project you might even be able to use raw Node.js without adding something like Express.[... 81 words]

Is there a substantial difference between using a Mac or a Windows machine for web development (particularly RoR)?
No matter if you are on Mac or Windows you should be using a Linux virtual machine for development, ideally running the same operating system as you deployment environment (I like Ubuntu for this). Vagrant is a popular tool for managing this kind of setup.[... 151 words]
Learning Linux really isn’t that hard, and it will dramatically increase your potential horizons as a programmer. Install Ubuntu on a virtual machine on your laptop and start running through some tutorials.[... 53 words]

There are two ways to approach this: you can try and learn HTML yourself, or you can use tools that will help you build websites quickly without needing to code.[... 114 words]
I think this is a pretty interesting idea—simulating these kind of conditions isn’t easy so I imagine many teams don’t bother. If it was good (really easy to get started with, great control and reporting tools, maybe helped set up the actual tests to replay) and I trusted the service I would definitely consider paying for it.[... 125 words]

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]
This is a big decision, and it’s worth taking the time to pick what’s the best fit for you. I recommend going through the tutorials for each one, building the basic application they describe and seeing which made the most sense to you. As a Django developer, I suggest trying that framework too :)[... 126 words]
What are some techniques, workflows, thought-processes etc. you would do as an experienced web-developer (front-end/back-end) that a new web developer might benefit from?
Maybe. One of the things I like about Node.js is that the raw abstraction it provides over HTTP is much closer to how the actual protocol works than the abstractions provided many of the more widely used frameworks such as PHP, Django or Rails. That might actually make it an effective learning tool—I’d be interested in hearing from some web developers who learnt Node.js as their first server-side technology.[... 87 words]
Does creating a zip file with php use more RAM then CPU? Or vise versa? Also, is it faster to use a system call, or the php zip library? Exec (zip filename.zip) vs. $zip =new ZipArchive().
You can find out the answer yourself using a very simple benchmark—just call time() before and after each option and loop them a few thousand times to calculate an average.[... 74 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]

Offer to volunteer at conferences. If accepted, you’ll get in for free and you’ll get to meet loads of people (including spending time with the speakers)—in exchange for a full days work manning desks, finding speakers in time for their talks, giving people directions and generally helping organise and clean things up.[... 104 words]
Unless I had a very good reason to use something else (a pure websocket/real-time collaboration app perhaps) I’d go with stock Django on PostgreSQL and maybe a bit of Redis. Simple, powerful, stable and works reliably.[... 50 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]

Did Mark Zuckerberg have any knowledge on building scalable social networks prior to starting work on Facebook?
I’m going to bet he didn’t have this knowledge, simply because back when he launched Facebook in 2004 almost NO ONE had this knowledge—there simply weren’t enough “web scale” products around for the patterns needed to run them to be widely discussed.[... 143 words]
