Certifications have always been a controversial topic for me. They’re either dismissed as time-wasters or celebrated as career boosters. When people ask me, “Do you recommend certification X? Is it worth pursuing?”, I find myself unsure how to respond. Having gained experience with a few technical certifications (such as OCP and CKAD) as well as language certifications (like IELTS and TELC German), this article is an attempt to break it down and figure this out.

“Open source” is one of the concepts that is widely used and at the same time is widely misunderstood. I think that is misunderstanding, not injustice leads to wave of frustration every time next company make a switch from Open Source Licence to Business Source License. HashiCorp, Confluent, Elastic, Redis and others did prioritize their business with Business Source License move. Do they being greedy? No. They just make money, as business suppose to do.
