Problem: Using Putty SSH to log in some hosts, I got “Couldn’t agree a key exchange algorithm (available: This email address is being protected from spambots. You need JavaScript enabled to view it., ECDH-sha2-nistp521, ECDH-sha2-nistp384, ECDH-sha2-nistp256)”.

Most frameworks come with some object-relational mapping tool (ORM) which more or less hides the differences between the different platforms and makes them all equally slow. Using the default option (MySQL in most cases) is rarely wrong, but it’s worth considering. Don’t fall into the trap of familiarity and comfort – a good developer must always make informed decisions among the different options, their benefits and drawbacks.
