Who writes code? The obvious answer is that developers write code. Who makes sure the code works? Many companies have separate QA departments that are responsible for making sure code works. The answer to this question also seems obvious. MORE
We are explicit about our dependencies, so we know what code we need to run to run a specific component. Lazy-loading and bundle splitting can have a huge impact on page performance: less code requested, parsed, and executed. You can see a demo here (check the code source ). MORE

The first step towards this goal is the recently announced move of the HammerDB source code to the TPC-Council GitHub repository. The previous developer owned GitHub repository sm-shaw github repository has been deleted and the TPC-Council repository will be the source code repository for ongoing and future HammerDB development. To understand the difference between the downloadable binaries and the source code view the post on HammerDB Concepts and Architecture. MORE
Readable code is usable code. The non-used code blocks saved for future use are sometimes forgotten and another developer could not be in want of changing the code of the legacy system. Such non-used code blocks may affect code readability in the future. MORE
Code coverage is a metric indicating the percentage of lines of code that are executed when running automated tests, specifically unit and integration tests , for instance. performance xml maven code code coverage tests jacocoIt’s known that having automated tests as part of your build process improves the software quality and reduces the number of bugs.

For this blog post I want to focus on how you can leverage Dynatrace to get a lot of insight into your plugin code. Part 1 – The code as it stood. As the plugin needs to run in less than a minute, even on very large environments I have to monitor the execution time of my code. MORE

I recently improved flame graph code coloring. Code-type coloring was a regex hack that took five minutes. My hack was the following eight lines of code: if (defined $type and $type eq "java") { if ($name =~ /::/) { # C++ $type = "yellow"; } elsif ($name =~ m:/:) { # Java (match "/" in path) $type = "green" } else { # system $type = "red"; }. And that's what I coded. I had similar issues with JIT'd code for Node.js. MORE
Whether you’re writing unit tests for your programs or finding bugs in closed-source third-party software, knowing what code you have and have not covered is an important piece of information.
