Condensing boilers became mandatory in UK just over 20 years ago

This is exactly the thing. In UK electricity price is set by the cost of generating it from natural gas. After losses, etc, you get about 1/3 of power in electricity compared to heat in the gas. And the heat pump has an efficiency fact

Interesting. In UK, I think the big construction companies would hire these bean-counters then use them to out-manoeuvre the ones that are hired to replace them. Quickly nobody knows what a reasonable price is, and the govmnt has to go wit

Would be interesting to read how the Austrian project was contracted out? It seems in the UK the big construction companies have got very good in extracting a lot of money from customers, wonder if things were different in Austria with this

Moved out of TCL and into Python in 2001. Perl was big at the time. But Python had REPL and numeric/numarray which swung it in my case. (Worked out well I suppose? Almost 1/4 century and still using Python)

Many comments here focusing on secrets and problems. But here is another way to look at this: Environment variables are the "indefinite scope and dynamic extent" variable bindings to make structured programs out of Unix processes.

No need to go as far as Africa. Basic landline telephones spread into poorer/more rural parts of Europe only in 1980s and 1990s. Until then it was either taking the bus to see people in person, or sending a letter.... E.g. quick search

Yes, and it was a huge thing at the time. The social effects of all this time coordination and time tabling are one of the underlying themes of Stoker's novel Dracula.

Exactly this. But you don't really want to bundle straight away -- think about the exact problem you have and then solve exactly that problem. After you've sorted a few problems like this think if a bundled platform is useful.

I didn't know about that, would have been right that Amazon pays damages to the copyright holder. But they did at least refund the price paid, so the readers were no worse off than at start. Generally not a big fan of Amazon-world, but

The terms of service in UK seem better in this regard than USA. Which/why did they remove the book?

by zzbn00 1y ago
I agree. And the cost of ebooks is often very reasonable, Amazon are selling lots (more than one can read in a lifetime) of superb stuff in the $1-$4 range. (Makes things really difficult for the modern authors though). Also a paper book y

Its great for when people need to be in the loop, looking at the data, maybe loading in Excel etc. (I use it myself...). But not enough humans around for 21 GB/s

Yes, but if you have decades of data, what turns on having to wait for a minute or 10 minutes to convert it?
17.
by zzbn00 1y ago
I think these would add only small amount of information (and in a DB would be modelled as joins). Only adds lots of data if done very inefficiently.

Humans generate decisions / text information at rates of ~bytes per second at most. There is barely enough humans around to generate 21GB/s of information even if all they did was make financial decisions! So 21 GB/s would be

Maybe that would be enough. But the belt-and-braces approach of superglue with silica gel bags in a closed jar, in a fridge, seems to work well and has meant the superglue is still usable when I end up needing it....

I reuse ones I find in consumer goods by putting them into a jar, together with open superglue bottle(s), and putting the jar into fridge. Not a scientific study, but it does seem to keep the glue for longer then just fridge.

This is a good and subtle point of law -- The City of London is a corporation "by prescription". But while it was created by neither statue nor royal charter, I doubt the parliament could not end it if it so decided....

But do general people know who is a scientist and who isn't? How do they find out? It isn't by membership of a learned society, it isn't if they are working at a university. There is no simple way for a general person to k

The whole episode is a nice and timely reminder of the difficulty of the society as a whole in dealing with scientists and understanding which ones are good, which ones can be trusted, etc. Academic societies such as the RS help, but as thi

There is a good dimensional analysis package `ezunits` in Maxima. Very useful for working through equations and then sometimes generating the c/fortran code directly from Maxima is fine.

"Filing" is distinct from "Filling". In this context "filing" means lodging the papers with the court, and that typically has an immediate automatic legal effect (the Automatic Stay).

Can confirm (but not recommend) that a VW Sharan will ford a stream (or at least quite deeply flooded road) with only the loss of the plastic engine heat shield from underneath.

I think daily bin collection was normal in London until the mid 1990s or so. Also post was delivered twice a day and picked up from post boxes at least three times a day!
