- Lambdas and Clean Code
-
As software developers, we behave like children. When we see shiny new things, we just have to play with them. That’s normal, accepted, and in general, even beneficial to our job… up to a point.
When Java started to provide annotations with version 5, there was a huge move toward using them. Anywhere. Everywhere. Even when it was not a good idea to. But it was new, hence it had to be good. Of course, when something is abused, there’s a strong movement against it. So that even when the usage of annotations may make sense, some developers might strongly be against it. There’s even a site about that (warning, trolling inside).

- 7 things a developer should know about databases
-
TL;DR:
- pg_stat_activity view shows executing queries, pg_stat_statements shows executed queries, queries can be logged;
- use a connection pool; make sure when scaling you do not reach max_connections;
- activate default_transaction_read_only and statement_timeout in your sql client in production;
- never login to production directly in the database OS/container: use a sql client instead;
- if pg_stat_activity shows queries waiting for lock, use the lock view to find which ones got them;
- when a SQL query has started, it will run until completion - doesn’t matter if the client is gone;
- use pg_terminate_backend to stop a query, and be ready for AUTOVACUUM.
