Better Dev Link

We know the feeling when we have a bug in production which is supposed to be caught by tests. So how to prevent that? What to test the test?

Let’s play with lesser known toggles available to us when it comes to font rendering and see what they do, let’s have fun and explore possibilities

Gitlab is very good at sharing their infrastructure setup. In this article, they explain the precise maintenance process to execute a major version upgrade of PostgreSQL.

PostgreSQL comes with many parameters for fine-tuning. Logging parameters are huge too. We will cover some fundamental practices to get the best out of PostgreSQL logs.

I know this feeling, I like my personal ec2 price check project but I don’t know how to bring more traffic to it.

Don’t push the responsibility of maintaining invariants required by your class on to its callers.

You cannot model probability with nondeterminism, and you cannot model nondeterminism with probability.

If you go shopping for CPU or read CPU benchmark/optimization you will see mention about L1/L2 cache and usually they are just a few MBs. So what are they and why they are helpful with mere MBs.
