You're telling me about compiling JS, to my story that is so old... I had to check. and yes, JS existed back then. HTTP2? Wasn't even planned. This was still when IRC communities weren't sure if LAMP is Perl or PHP because both were equally popular ;)
you are supposed to have written the tests and to have written your code with pair programming,
I commented out the tests because they were failing, pipelines were green so I merged. Now it's running on prod. What do you do?
I’ve thought of doing pen testing (later on in my career), but I’ve come to realize that it is better if users just started using privacy-respecting FOSS software like Signal, because if you give a hacker enough time, patience, and the right resources, they could hack into anything.
Your idea of pentesting is so far from what it looks like in reality that it's probably not a path for you, at least not now. Let me explain: how am I going to protect my banking app using Signal? How will I know if our JSON unmarshalling library used by transaction service isn't vulnerable or exploitable? What FOSS software shows me live dashboards of deployed software in container and their security risk?
everybody still needs them and they’re not going away any time soon.
Bank is a civilization old concept, it has always been here and will be. Banks are so durable, they will run after our civilization ends.
Learning from a documentation. Got a book, went offline and finished the book and training exercises without looking for anything online.
Noticed that Hibernate session (DB ORM session) was leaking to Jackson (JSON marshalling), potentially causing infinite n+1 problem. Changing a few lines of code to lazy loading and fixing the session leak reduced our daily data transfer from DB from 5.6Gb to 170Mb.
Not sure if this was the biggest optimisation, but definitely the dumbest issue.
It's supported in MySQL and MariaDB out of box:

In Postgres there is an extension for it:

I'm with OVH and Kimsufi and I don't know what you're even talking about. Do other providers make you install something locally?
Seems like you have some organizational and technical debt in the company that would be worth addressing before agreeing to be on-call
Most likely debian or debian-distroless
What were the architectural decisions you made?
There are two schools:
Remember that Google was written in Python and Java. Facebook in PHP. iOS in Objective-C. GitHub in Ruby on Rails.
