Tech debt gets worse before it gets better
Projects to pay down tech debt tend to start by making more tech debt. The level of tech debt gets worse before it gets better. The new, cleaner code is just adding to the mess until it allows you to finally delete the old code.

Devious SQL: Message Queuing Using Native PostgreSQL
An interesting question came up on the postgresql IRC channel about how to use native PostgreSQL features to handle some sort of queuing behavior.

Speeding up VSCode extensions in 2022
I was curious to know if the functionality of VSCode can catch up with the native speed of some editors, such as Sublime. That led me to seek out where some bottlenecks may be and where time is being spent. In this post I look at both the internals and extensions.

We’ve trained language models that are much better at following user intentions than GPT-3 while also making them more truthful and less toxic, using techniques developed through our alignment research.
