In addition to Set Theory and Formal Logic, Computer Science relies heavily on Boolean Algebra, Graph Theory, and other areas of Discrete Mathematics. Computer Science is inherently cross-disciplinary, but at its core it is closer to Mathematics than it is to Engineering or Science.

You miss the parts that are very close to Linguistics and Information science: Ontologies, Information retrieval, Semiotics, and the all-important Human-Computer Interaction - how to build a computation environment that's efficient for humans to interact with. Maybe this is not a well-defined problem in a mathematical sense, but it's at the core of all programming activity beyond the level of micro-instructions.

This is not merely cross-disciplinary work; those are also essential parts of the science of computation, little related to mathematics yet highly relevant to all projects in the computing field, either in research or business - although many are unaware of their relevance.

Who says there would be no constraints? Merely because there's no threat of hunger and cold, doesn't mean that creating art would have no challenges of its own. Many artists in history could create their craft because they were wealthy enough not to need other work.

Even if there is not a pressing need, artists can use self-imposed limits to explore the possibilities of their medium of choice.

No, I had a Teac DSDD drive on my TRS-80 Model I. I had to build a custom disk controller to support it though. This was in '80, so it predated the IBM PC by about a year and a half. Also, the PC used soft sectors, didn't it? The TRS-80 drive controllers were all hard sector.

I also had a Shugart 35-track SSDD drive, if I remember correctly.

It's obviously been a while, but I remember 35 track hard sector SSSD, 40 track hard sector SSSD, 40 track hard sector SSDD, and the brilliant Holy Grail of 40 track DSDD.

I think you got PLA and ABS backwards.
Could well be. I often get lost in the TLA soup, especially when I'm trying to justify spending money on a new toy.

It all comes down to me being excited by the new developments in the low-end CNC world :)

ABS melts at around 200F, not 200C. But even at 100F you'll find that a lot of plastic structures lose their integrity. And it they're load bearing in any way, they're goners. PLA has a higher melt temperature, and Nylon higher still. You might be able to get away with those.

Still, aluminum! brass! wood! soap! er ... wax! ... er ... well, I dunno. I just like the idea of a diversity of material to work with. If I had more cash, I'd have both a 3D printer *and* a CNC router. And if I had even more? A full on 4+ axis CNC mill!

I will have one of these soon.

It will work on materials other than soft plastics and nylon (e.g., wood, brass, aluminum), so it will be usable for fabricating real parts that can withstand temperatures like southern California car dashboards.

The downside is that the affordable ones are 3 axis, so you can't have overhang in parts. With clever use of zeroing and flipping the part, you can mitigate that somewhat.

I guess if I was willing to cast in metals, a standard 3D printer would be OK. Print in wax, make a mold, and cast. But that seems like a lot more work than its worth for most of the things I want to fab up.

I said "Not if you choose to be one of the people who doesn't work and lives from the basic rent"... or also if you can't choose and are forced into it. Life is long and you never know what tomorrow brings.

With a basic income, you have a choice that you didn't have before. This is what those extra taxes are buying you (in addition to reducing competence because other people will choose not to apply to the remaining jobs). Being universal, you also benefit from them.

Because I have to pay taxes to support them?

Not if you choose to be one of the people who doesn't work and lives from the basic rent.

...making us less competitive internationally. Which causes more jobs to be outsourced...

Do you realize that those arguments wouldn't apply if the rent was truly universal? I.e. if *all* people could apply for them, not just people from a single country, all workers in the world would face the same increases in costs, thus not making any difference in their competitiveness.

...or just vanish due to being economically unproductive.

Again you're assuming 1) that such thing would happen and 2) that it's a bad thing. Why?
