> laser pulses > phased-array I'm not well versed into RF physics. I had the feeling that light-wave coherency in lasers had to be created at a single source (or amplified as it passes by). That's the first time I hear about

On the brand new and shiny 486 running dos and windows 3.1 that my father bought, on the qbasic language. With only a paper book as reference. No llm, no stackoverflow, no pageranked search engine, no internet, and not even Ctrl+F. In these

Of note is that once you've got planes, you can define points as intersections of n hyperplanes. In 2D, 2 intersecting hyperplanes (=lines here) will define a point. But what if these lines are parallel? Well you just got the "poi

Most programs should be written in GCd languages, but not this. Except in a few cases, GCs introduce small stop-the-world pauses. Even at 15ms pauses, it'd still be very noticeable.

> "theory building" Strongly agree with your comment. I wonder now if this "theory building" can have a grammar, and be expressed in code; be versioned, etc. Sort of like a 5th-generation language (the 4th-generation

A bit late to the discussion, but this has deep connections. As a programmer, your job is provide business invariants using complexity management techniques. And checking that your state space is small is a tool with gigantic payoff. Mainta

Tabular data is everywhere in the corporate world. I feel like there is a zillion opportunities to make money with these transformers. But how to enter that market remains a mystery to me.

Merit order is a hidden subsidy. Other means of producing electricity that have a theoretically lower marginal cost will need to curb their production.

1 > 0. And most of the cost comes from maintaining engineer's salaries on a single project. If new projects get ordered I'm quite confident costs will move closer to the actual bill of materials, per unit.
