    Turso now includes unlimited active databases in every plan. We already had unlimited databases, but we would charge you based on how many of them were active. That is now gone. You want a database, you get a database.

    My 6 year old just said 1 + 1 = 11. I fear he may be learning Javascript. It may be too late for him...

    C is not just a bad language. It is a demonic instrument, that leaves scars on your soul that not even time can heal. We had a small bug recently where one extension that works with SQLite stopped working with libSQL. One of our engineers, @iavins, spent a whole day debugging

    What is faster? An O(n^2) algorithm in Rust, or an O(logn) algorithm in python?

    We rewrote our routing layer in Go. It is now much better. Graph is chef's kiss - kind of graph that every engineer wants to see.

    An engineer just saw an unexpected outlier (7ms) for ops that should take 200us. Asked me if it was a priority to investigate, and now I don't have the heart to tell him no. What if this is a backdoor on a compression library ?

    in Ontario you can't buy dairy from, say, Quebec, without paying tariffs - close to 300%. And yes, that's real.

    I guess we're moving out of Github. I temporarily made @penberg our temporary interim VP of Engineering and I already regret it.

    Mitchell is just conveniently forgetting to mention some important context: he's a billionaire. For us mere mortals, who really can't afford life... this is all equally true. Nothing changes. Kids are the best. Go have kids.

    I was someone who through my 20s wasn't even sure if I wanted kids. Work was my passion and I enjoyed it deeply. I filled up two passports. I did well financially. And yet, it's incomparable to the joy and purpose having children has given me. Like, not even close. Its crazy.

    If you can solve this problem using Go, Kubernetes and SQLite, we are hiring at @tursodatabase (exclusive in the Americas)

    i have a very simple question i ask during phone screens: print each level of a tree on a separate line. 90% of CS grad candidates just can't do it. someone needs to investigate these universities.

    Here is one more Limbo story, the most mind-blowing so far. After the announcement, we started receiving a large number of contributions from a man named Preston Thorpe (user PThorpe92). All of them high quality contributions, implementing SQLite functions, fixing the io_uring

    Today we have decided to make @penberg 's experimental project, an official Turso project, following its great success. What if instead of just forking SQLite, we were to completely rewrite it - in Rust? That's our moonshot - codename Limbo
