A few examples from past are: Library cache object hash values added to allocated shared pool chunk names (2010) The above technique is used for some other all....

A musician sight-reads a piece when they play it from the sheet music for the first time. Depending on their experience level and the difficulty of the piece, sight-reading can have mixed results. This variability in quality is extended considerably when an entire ensemble attempts to sight-read a piece – key signature changes can be missed, players can miss entrances, etc. While sight-reading is an important skill for musicians, it is no....

Problem synopsis I’m a huge fan of sqlc’s approach to code generation. I’ve seen sqlc called a reverse ORM , and I really like that moniker. However, as a sqlc newbie, I’m still discovering its edge cases. Today’s edge case is using postgres UPSERT queries with sqlc. The crux is that when upserting, it’s necessary for unique key conflicts to occur so that the UPDATE portion of the query executes. But non-null uuid Go types tend to....

Where to begin! Where to begin… Lets start with a good measure of success, one that I think most engineers could agree on: a from-scratch rebuild of a complex, internal tools app. Success with rebuilds is often fleeting, as many can attest. There’s risk involved. Extending the challenge further, lets assign (most) of the task to a team of platform engineers who aren’t too familiar with modern front-end technology – and then say that we su....

I am speaking about OAuth2 and Open ID Connect with ASP.NET Core 8 at Rome .NET Conference 2024 on March 22 and then, less than a week later, at WebDay 2024 in Milan. I am always particularly excited when I can present the stuff I’m currently working on. Being forced to share as I learn encourages me to go deeper into the topic to reinforce my comprehension and better explain it to the audience—a win-win situation.
