The complexity of emerging software applications requires new approaches to understanding and then efficiently building, testing and debugging these systems. Today’s software uses cloud resources, is often embedded in devices in the physical world and employs artificial intelligence techniques. These three factors make today’s software systems an order of magnitude more difficult to develop.
Today, we deployed HTTPS by default on Stack Overflow. All traffic is now redirected to https:// and Google links will change over the next few weeks. The activation of this is quite literally flipping a switch (feature flag), but getting to that point has taken years of work. As of now, HTTPS is the default on all Q&A websites.
You’re not alone, jclancy. In the five years since this question was asked, there have been over a million other developers who got stuck in Vim and couldn’t escape without a bit of help. Indeed, the difficulty of quitting the Vim editor is a common joke among developers.
t’s been 3 months since I first wrote about our efforts to scale Git to extremely large projects and teams with an effort we called “Git Virtual File System”. As a reminder, GVFS, together with a set of enhancements to Git, enables Git to scale to VERY large repos by virtualizing both the .git folder and the working directory. Rather than download the entire repo and checkout all the files, it dynamically downloads only the portions you need based on what you use.
Don’t even consider microservices unless you have a system that’s too complex to manage as a monolith. The majority of software systems should be built as a single monolithic application. Do pay attention to good modularity within that monolith, but don’t try to separate it into separate services.
