    I'm evaluating Flow for CDC. Do you support logical decoding messages from `pg_logical_emit_message`? This would allow us to add audit metadata[^1]. [^1]: https://www.infoq.com/art…

    Goodhart's Law in action. Any "product quality" metric will be gamed to the point of uselessness as soon as it gains traction. In other words, services like this one can only work …

    Looks interesting; thanks for writing this! Does it support nested structs? Sometimes that's more natural than a flat struct.

    I was intrigued, but after visiting your website I'm ambivalent. The only way to truly combat shilling is to fully embrace a model where each person sees reviews only from their ow…

    No metric can escape gaming when you apply it to rational actors (Campbell's Law / Goodhart's Law). Blind devotion to metrics is just as bad as no metrics at all.

    Have you evaluated compression algorithms that support custom dictionaries, like zstd? You could generate a compression dictionary for each domain, or just for those above a certai…

    Why not increase the minimum font size instead?

    Reviews on sites like Amazon or Yelp are a monoculture: everyone sees the same set of reviews and the same ratings. This creates leverage that makes it worthwhile for shills to spe…

    Fake reviews can be seen as an instance of Goodhart's law, where the metric is the rating or score of the business. Initially those ratings may have high correlation with something…

    Images are inherently visual, and they seem to have more irreducible complexity than music. Music has a lot of structure and repetition that seems like it could benefit from abstra…

    Are you familiar with Overtone[1]? I'm no musician, but as a developer I'd think building your own musical abstractions via code would be better than any visual IDE. [1] http://ove…

    Do you encrypt your keys before exporting? How do you ensure you'll remember the passphrase, if so?

    I'd love to see a kind of reverse-DNS-style tagging system, so that when my browser comes across a dat:// link it can automatically show me that this content is commonly tagged as …

    The problem is that none of that is apparent to an outsider . You can tell developers that filing radars is important until you're blue in the face, but as long as dealing with Rad…

    It's not a question of "should". You can't beat the market. You can fight it, but you will lose. And so will your customers, most likely.

    There's a fundamental difference between physical property and intellectual "property": an owner of the former can conceivably hire guards to protect or restrict access to that pro…

    Thanks, though I'm still getting authentication errors. I don't want to use the JS library since I'm not working in Javascript. I'd kill for a working code sample, in any language.…

    By coincidence, I was trying to test out this exact thing yesterday and was having trouble with authentication. Does anyone know what they mean by "ISO8601" in their instructions f…

    Even in a (totally unrealistic) scenario where N dollars are "useless" to you, but N+1 get you something of great value, it's not true that the (N+1)th dollar has greater marginal …
