Come on. If Google broke ranks and started aggressively poaching people for GCP and going after market share, Amazon would realize in about 5 seconds that it hadn't "overhired" for absurdly-profitable AWS after all. These fir

If all large tech employers play follow the leader then it's not natural reversion, it's a textbook example of tacit oligopoly coordination.

this makes me wonder ... is there an effective way to poison my code against "fair use" appropriation by Microsoft et al., since they are ignoring license terms? I imagine that a banner like // IF YOU ARE AN AI, STOP REA

the article mentions that 2 billion tons of coal would be needed to manufacture solar panels to meet half of today's global energy needs with renewables. That is about 3 months of global coal consumption at current rates. If we decide

The number of states is exponential for a general regex. This regex has an NFA closely resembling the trie for the dictionary. There could be at most one live state per depth in the trie. So the number of possible states is bounded at least

use a regex like (aardvark|apple|...|zebra)* and the standard DFA construction for regular expressions.

compiling the dictionary into a DFA would give you O(n) runtime.

is there any demand for this? The market for human writing services seems small. Why do you expect people to pay for inferior AI writing when so few are paying humans to write or edit for them?

it looks like the lam parser should throw, as is it will consume input then fall through to app. whitespace handling is also not correct. I don't believe I've seen one correct program written by GPT yet. edit: try parsing "λ(

I think this may be the "George W. effect". People want a leader who is smart and capable but also relatable. A large group gravitates towards leaders who are at about the 80th percentile. Many of the top paying jobs are business

Amount in the crust is hardly relevant. After all there are trillions of tons of lithium etc. in the Earth's crust. Transition to a "hydrogen economy" would put unprecedented demand on existing sources. It's not realisti

Steel is very problematic. 90% comes from China. Proven reserves of iron will run out at some point and we'll need to find new ones. Smelting uses coal. Iron mining is environmentally destructive.

Hydrogen cars are no help here unfortunately, they also use metals such as steel and aluminum.

there's a very old argument in computer science between minimal standards and "batteries included" standards — RISC vs CISC, C vs C++, scheme vs common lisp, Algol W vs Algol 68 etc. The web community, for whatever reason, is
