Writing = Thinking Don't outsource it to AI
You don’t hate math. You hate the way it was taught to you. But because you haven’t learned math properly, you confuse correlation and causation, and therefore think that you hate math.

Learning Haskell/FP often expands people’s minds. In a world dominated by Java + Python intro courses, being forced to see computation in a new way is very empowering. There’s almost no downside to learning these techniques and having them in your toolbox.
Want to learn how database concurrency control really works? Check out this paper from @YingjunWu and @andy_pavlo! It dives deep into the most widely used type of concurrency control today: multi-version concurrency control (MVCC). The basic idea behind MVCC is for a database…
It took three years to finish, but our follow-up to the 2006 "What Goes Around Comes Around" is finally out! Stonebraker and I examine the last 20 years in databases and discuss why relational databases + SQL will continue to remain on top. 📄PDF: db.cs.cmu.edu/papers/2024/wh…

10 Haskell/GHC features I avoid: >>= ; let if-then-else case-of import data type class instance They’re not always a problem. But, they’re overused, and can often be replaced by better alternatives. Here's why I avoid each, and what I do instead... 📷

New blog post: Things DBs don't do - But should! thenile.dev/blog/things-db… It is based on my keynote at #ddtx23 - lots of people asked about it and there were no recordings. So I put my thoughts on writing.
