Overheard in Chingu

TIL…specifying the correct parameters on a function call is pretty important. I have two objects of the same class, but passed the wrong one to a function and then wasted 2 hours trying to figure out why results didn’t match my expectations.

If there are ‘one to many’ relationships in your DB then the SQL side will bring back an entry for every possible combination of those relationships… then the C# side removes the duplicates. Apparently it is way more performant to build a better SQL query (Select and Where statements) than a default include statement.

What… beauty is this and how did I get there? OHHH this is so cool. Chrome Canary

I crashed an app that has ~200k request per minute

I learned about MongoDB unified topology design, the concept that MongoDB “”is always connected””, so you can basically start making requests before a connection has being established. This caused request to pile up and be sent all at once when a connection has being established.

TIL you can ‘hint’ to a browser to use the GPU to handle an element full-time with the CSS will-change property. Prevents odd moments when CSS animations hand off between CPU and GPU

GraaaaphQL GraaaaphQL.
