In general, it is common to have two answers in these kind of cases:  Use monitoring to check if the application is working properly.

Terminal telekinesis

Tl;dr In my experience, software developers’ skills regarding tasks in a terminal range from desperately slow to impressively swift.

Namely, how to feel productive on a terminal, after using omnipotent integrated software environments for so long. This article aims at bridging this gap by sharing carefully selected tips that can, in my opinion, dramatically increase the terminal productivity of…

We use Git for versioning our code and sharing it with others. This is what Version Control Software (VCS) is used for, afterall.  Thinking like this, it is easy to believe that you can Google your way through Git mastery by searching how-to’s every time you’re stuck on a specific Git-related problem.

Cache me if you can – 2

Introduction - scope of the article This series of articles deals with caching in the context of HTTP. When properly done, caching can increase the performance of your application by an order of magnitude. On the contrary, when overlooked or completely ignored, it can lead to some very unwanted side effects caused by misbehaving proxy servers that, in the absence of clear caching instructions, decide to cache anyway and serve stale resources. In the first part of this series, we argued that caching is the…
