I was wondering last night: are any of the fundamental forces "blocked" by an intervening object? I assume not, since there is nothing like that in the equations. But that is kind of interesting, since sometimes you hear talk of h

When I was still much more skeptical of AI, I asked ChatGPT to write me a proof of the Goldbach Conjecture. Of course it didn't, but it gave me a several-screens-long research program for how one might get there, with a few alternate p

I think yes. You're saying that the invoice is generated from other data in separate tables, and it should be immutable even if that data changes. So today you are copying everything used by the invoice. That's exactly why I start

In the Postgres version, you can use a rangetype or multirangetype over any base type (integers, inets, frammishes, etc). This is a generalization of SQL:2011, where PERIODs have to be on date/timestamp/timestamptz columns. I have

For application time, everything lives in one table (although you could partition it). The biggest performance hit, I suspect, will come from GiST indexes instead of B-Trees. Some general GiST improvements are on my TODO list, and I learned

Hey I worked on this! Thank you to everyone here saying they are excited about it. I often hear doubts that anyone wants this. Perhaps that's why vendors have been so slow to add it. And thank you 'bonesmoses for writing about it!

Yes, I su to the user. Typically I have it run a tmux session for each "project". That makes it easy to get more windows without su'ing over and over. Also its tmux sessions all get a yellow status bar (in ~claude/.tmux.

I know there are VM solutions, but I've been happy with a separate OS user (named `claude`). He has similar dotfiles to mine, but no secrets. My own home directory is 0700. He has his own ssh key that I added to my github profile, but

Does this scheme give a way to progressively load slices of an array? What I want is something like this: ["foo", "bar", "$1"] And then we can consume this by resolving the Promise for $1 and splatting

I've seen this a lot when someone wants to add "workflow automation" or "scripting" to their app. The most success I'd had is embedding either Lua or Javascript (preferably Lua) with objects/functions from

Great article! I'm looking forward to reading the rest of the series. I noticed a couple details that seem wrong: - You are passing `context` to `log_then_get` and `get`, but you never use it. Perhaps that is left over from a previous

How did JFrog know this github token was so powerful, compared to all the other ones I'm sure their scanner detects? What caused a human to get involved?

Calagator has been dead for years, and I don't understand why. Way before the pandemic: agreed. Most of what I see there now is business networking or people selling something. But there are still things happening, e.g.: - pdxpug (Post

Oh this is very helpful! When I read Turing's paper some years ago, this really confused me. The best sense I could make was that "circle-free" means "halts". But in popular explanations, writers often equate "

I think it would be cool if stdout worked something like the clipboard, where you have different representations, and when an application copies something from the clipboard it selects the representation it wants. I'm not sure how to a

Not exactly what you asked for, but you should look up Chef (not the devops tool). It was part of an MIT Mystery Hunt one year. You could certainly write the recipes with a royal style.
