PDF is the obvious successor. Though there are some things you can do with PS you can't do with PDF, because PDF AFAIU isn't a Turing complete language (though newer versions of PDF allow embedding of Javascript, IIRC).

IIRC the Erlang VM does the second (schedule on function call). Since Erlang is a functional language and loops are done via recursion, this works out fine.

While I agree there are some very positive aspects to floating nuclear power plants, I'm somewhat skeptic about some of these plans that use molten salt reactors. A thin-skinned reactor filled with a water-soluble fuel sounds like a po

Enriched uranium would not make a particularly impressive dirty bomb. Spent nuclear fuel, or some specific very radioactive isotopes, maybe.

The entire point of the LVT is that the land value includes things that your neighbors (or society in general) does to make your lot more valuable.

The government keeps tabs on real estate deals and makes an estimate on the value of the unimproved land. Or for an extreme case, the government can buy some old property, demolish whatever building is left standing there, and the sell the

Sort of, but not really. The speed of sound in water is 1480 m/s (at 20C), and is independent of the length of the vehicle. Ships are sort of special because they operate at the surface of the water. Submarines operating submerged have

Yes, it has to do with the beam, and some other things. A widely used method for estimating the propulsion power requirement for ships is the Holtrop-Mennen method. It has a dozen or so parameters, which you can play around with at an onlin

You may doubt the effect of the waterline length, but it's really basic naval engineering: https://en.m.wikipedia.org/wiki/Wave-making_resistance

Well, nowadays the meter is defined in terms of the second, so that would be a circular definition. ;)

In practice, when navigating by pen and paper, what you do is you measure a distance on the chart with a divider, then you put the divider (with the previously measured distance set) to the north-south scale on the side of the chart to read

The main difficulty is that for ease of calculation you'd like a cartesian grid, which maps poorly to the spheroid shape of the earth. One solution is UTM https://en.wikipedia.org/wiki/Universal_Transverse_Mercator

Kind of hard to beat nuclear fuel, if energy density is what you want. But sure, in many situations that's not a deciding factor.

(Not having access to the paper) So are you saying the reaction is 10 H2 + 3 CO2 <=> C3H8 + 6 H2O Of course, neither this nor the reaction mentioned in the parent comment matches up with the diagram in the linked article which says &q

You can see on the pictures that the ship is very narrow in the middle (that becomes the stairwell/elevator shaft for going down into the undersea researchy areas), so when it stands on end, the waves cause relatively small changes in

TBH, I'm not sure CORBA is as bad as its reputation tells. It's a hard problem space overall, and seems nowadays we're reinventing (parts of) CORBA with things like gRPC etc.

In Europe, many countries banned lead paints for household use already in the 1920'ies or even earlier. In 2003 there was an EU wide harmonization outlawing lead paints. The article you linked to is apparently about some lawsuit where
