How Exception to the Convention Does More Harm than Good
We have a project, and to make it easier, we use specific standards. E.g., we use spaces in every file.
But sometimes, we get to a situation when these standards are stressful. We don't understand them and just want them to bend over. How does our short-term need for pleasure affects long-term well-being of the project?

Your Jest Tests are Leaking Memory
Jest is designed in a way that makes memory leaks likely if you’re not actively trying to squash them. For many test suites this isn’t a problem because even if tests leak memory, the tests don’t use enough memory to actually cause a crash. That is, until you add one more test and suddenly the suite comes apart. In this article, we’ll walk through why it’s so easy for Jest to leak memory, how to tell if your tests have a memory leak, and then how to debug and eliminate leaks in your tests. Even if you don’t use Jest, it’s still useful to understand the process in case you need to debug memory leaks in other javascript code.
Flaky tests are automated tests that are non-deterministic. That means they may pass or fail when executed against the same build artifact or deployed system.
If you’ve ever retried the execution of a failed test run in your CI/CD pipeline tool without any code or config changes in order to get a failing test case to pass, that’s an indicator that you have a flaky test case.
Why Serverless Teams Should Embrace Continuous Refactoring
Serverless adoption brings promises to many organizations! Promises of cost efficiency, engineering efficiency, and business efficiency. However, serverless is not a technology that, once successfully adopted, can be left unattended to rust.
The motivation to adopt serverless should never be to get the job done and never look back. If you adopt it with this attitude you will inevitably get into the legacy migration juggernaut that will haunt you much sooner than you anticipated.
