   I am curious if we will someday build AI systems that are stratified with layers alternating between "statistical" like neural networks and "symbolic" like the older AI approaches. For example once your image recognition

   When I read Kevin Mitnick's Ghost in the Wires , what impressed me was how he'd combine social engineering with technical hacks. For example even if people did call their boss or Kevin's alleged employer (the utility com

   It reminds me of a point from non-Euclidean geometry. In Euclidean geometry a triangle has 180 degrees, but in hyperbolic or elliptic geometry it has more or less (I forget which way). So you could start measuring triangles to find out whet

   I'm not Greek although I have a lot of a Greek friends. I taught myself ancient Greek and can (barely) communicate in modern. I'd say that ancient Greek is about as far from modern as Chaucer is from modern English. Even Greeks ca

   I agree with grtrans that it is hard but not impossible, even while holding down a regular job as a software engineer. I took a year of night classes in ancient Greek at Harvard Extension School (they'll take anyone with a credit card

   I've tried it a couple times but didn't see as dramatic a speedup as I'd hoped either. What has worked for me is storing a full array in a single row of a regular Postgres table. Then if you have to load e.g. 1 million FLOATs

   I wonder how hard it would be to give Postgres a pluggable query planner, so that extensions can try to improve on its results. Then people could try things out without Postgres committing to something too soon. I'm still learning what

    In startups you often have tech that is more general than it needs to be, and you start thinking about all the opportunities, but it can be a mistake. In your go-to-market strategy, you need focus. If you say, "We have 3 business model

    If you freelance, there are three ways to earn more: work more, charge more, or hire. A few years ago I made a spreadsheet to model charging more vs hiring some people. The problem with hiring is that you have to spend a lot of time on unbi

    I think that is a great way of thinking about it! Composite types and user-defined types are very useful and it makes sense to see them as inspired by object-oriented ideas.

    Hi Craig! Postgres refers to itself as an "object-relational database", but do you think the "object" part is meaningful today, or just a label left over from the 90s? As best as I can tell, it just means that Postgres h

    I've always found it a little funny that SQL was originally designed for non-programmers, sort of like AppleScript. I used to think neither of those panned out, but in fact there really are a lot of smart not-programmers who can use it

    Chapter 11 of The Idea Factory by Jon Gertner (a book about Bell Labs) has a fun story about the first transatlantic telephone cable, completed in 1956. According to him, telegraph cables were attempted as early as the 1850s, but the

    This looks very nice! I have something like this for my own projects, and my favorite piece is having detailed tests that I don't have to re-write every time: tests for Devise, tests for Stripe subscriptions, tests for many-to-many use

    Not smooth breathing and acute, but Unicode has two codepoints for acute accents (sort of). One is the modern Greek tonos, which often looks just like an acute accent but sometimes appears as a dot or straight vertical line, and the other

    If you really want some fun, try explaining to people the difference between modern Greek tonos (e.g. ή, Unicode 03ae) and ancient Greek oxia (e.g. ή, Unicode 1f75). Or in UTF-8: paul@tal:~$ od --format=x1z tmp/tonos-oxia 000

    Okay, thanks for the reply. I asked about this benchmark once before (almost a year ago I expect), and was told roughly the same, so I was hoping things had improved by now. I understand it's just a benchmark and you have other things
