This famous video filmed at the Sasquatch Music Festival 2009 is often shown in corporations, team working classes, etc. and it actually shows an interesting aspect in psychology: the role of leading with a example (even if weird) and imitation.

@belldotbz I'm a Brit who literally stopped a feature getting called this in a product I have worked on with American colleagues 😂

[Mark Leith @MarkLeith]

@sunbains @tzkb Up until MySQL 3.23 there was only the ISAM engine, no transactional engines. In 3.23 the engine interface was added to include BDB (later removed) for a transactional engine, with MyISAM added as the new default from an extended ISAM. All other engines extended from there...

The default local dev database driver for new Laravel applications should be… 🌶️

@samlambert Indeed, as well as humility.

Consistency Locks -> Clocks

[Sunny Bains @TiDB @sunbains]

The idea of locks being the only mechanism for isolation to guarantee the consistency are long gone. When these ideas were being debated, the data sets were very small, compared to today and distributed meant another computer in the same building somewhere (mostly).

The state of the art in transaction coordination and consistency mechanisms has gone beyond distributed locking because it just doesn't scale. It has shifted in favor of algorithms that use time based coordination in distributed databases.

[Connor on SQL and Database @connor_mc_d]

@gwenshap My point is - whatever the language, whatever the app - if the task involved requires a lot of interaction with the data, then you want to run your code close to the data. PL/SQL can be a drop-in fix to lots of problems created where people didn't understand this axiom.

Apparently people are still putting functions in their database and it makes me upset enough to make a video about it
