Predictably you're criticizing the question rather than answering it. That's boring. Dogs and doghouses is supposed to be sufficiently contrived that you don't get hung up on whether it's the correct model. Although init

A common pattern I still haven't solved is this: I have table A , and now I want to add table B and give it one row for each row in table A . Then I want to add a foreign key column to table A pointing at the row I just added. Of

Thanks! I've been using ncftp but I'm not really happy with it. I will give lftp a try. Naturally if you have ssh access everything is a lot easier. :-)

It's not quite the same as `cp -r`. Tar will create the directories if necessary, but it will also drop the files into an existing folder hierarchy. So you could use it to create/update a few entries in an existing tree of files.

Like many Unix commands, if you don't give cat any files to read, it reads from stdin instead. So first he runs the command (as he typed it), and then while cat is waiting for input he pastes in whatever he copied from the website. Ano

Hover doesn't work on mobile, so I'm not surprised it's disappearing. One trend I miss is the textured, paper-like backgrounds. It seems like they were everywhere a few years ago, and then they disappeared. I think Stripe had

In college I helped a lot of people write papers, and almost always they were trying to "sound academic", and the sentences were so complex they didn't even parse. So I'd ask, "What does this mean?", and whatev

Is it really all about music? It seems like the Echo could become an IoT hub also. Or since it has an app ecosystem, perhaps it will do things you'd do now with Synology/FreeNAS. I would love to see "a server in every house&q

Just supposing we really are seeing the space construction projects of a distant civilization, it seems not impossible that ironically we might be seeing them before they can see us.

I'm aware of Gnustep, so I was hoping someone would mention it. But I was hoping for more than one word. How many people are using it in production? Have they had good experiences or bad? What are the surprises they've encountered

I have taken to calling certain features "Turing Complete" (in a joking-but-not-really way). Most often they are seeking some kind of enterprise customizability: "workflow", survey skip logic, custom reports, white label

I am fascinated that no one uses Objective C on the back end. Fast, low memory, quick to code in, high-level-enough, a mix of static and dynamic typing, and no garbage collection. Also plenty of expertise you can hire for, maybe already wit

Yes, it can make a huge difference. I did this once when I had arrays of ~1 million floats and had to compute statistics on them. I wound up implementing a bunch of stats functions as C stored procedures that operate on arrays, and brought
