My 1992 FTP site
We did not get to see the web until at least 1993 when Mosaic came out (though we had to use Chimera on the Appollos). I haven't found my first email but I think it was around 1985 when I went to conferences announcing the importance of email, in particular to us in Australia. Hard to remember those times.

The mess we are in with scientific publishing
After this judgment a great number of the abilitati were given permanent posts, thus filling up vacancies for some time.
The pressure this type of thing puts on scientific publishing is enormous. Referees, while trying to make judgments on papers, now have to consider that they are deciding the careers of young people, the grants for older people, that the prestige of the journal will affect jobs and grants. The reason the pressure is so enormous is that the job and granting committees don't look at the papers, just the numbers.
The job of a referee has become impossible, at the same time that there is more and more need for referees since scientists are being forced to publish more and more.
Scientific publishing must free itself from these pressures.
Thinking about this situation brought back to mind some thoughts of Bernhard Neumann.

Arguments for funding
"The next argument I keep hearing is that the worldwide web was invented at CERN which also hosts the LHC right now. If anything, this argument is even more stupid than the war-also-wastes-money argument. Yes, Tim Berners-Lee happened to work at CERN when he developed hypertext. The environment was certainly conductive to his invention, but the standard model of particle physics had otherwise very little to do with it."
I am glad that some physicists are being a bit more honest in their arguments for science funding. (However even this statement is inaccurate since Berners-Lee did not invent hypertext.)

Sleeping beauty problem III
I am writing a third post about the sleeping beauty problem partly because I have seen Sean Carmody's post (26th August) in which he describes the problem and expresses his uncertainty about it, and promises an opinion in a future post. We are waiting, Sean, for your ideas on the matter!

Span(Graph) III: Circuits with feedback
The two main operations in $\bf Circ$ are composition and parallel as for straight-line circuits, and there are a variety of constants.
Today we describe the operation of composition of circuits with feedback in $\bf Circ$.
