Comment no flight involved? (Score 2) 230

When I was a grad student at Bell Labs in 1983, a senior programmer told me about how she first programmed, when the labs were in New York City. She would write her program VERY carefully, punch the cards, put them in her briefcase, and fly to Washington, D.C. where she had access to a computer. She would give the deck to the attendant, wait a few minutes, receive her output, go back to the airport, and fly back to New York.

Comment Re:What's the cost to use a real rng vs psudo (Score 1) 86

A technique I've seen used for scientific purposes is to run a Zener diode in the high slope region and subtract DC, leaving a residue of quantum noise. I would think that with current technology such a package could be very small and cheap, though I don't know what is involved in reshaping the spectrum from 1/f in hardware.

Comment teacher competence (Score 1) 399

While some teachers are just plain incompetent or ignorant, that is not the only factor leading to poor performance. Here are several more: (a) teacher training is poor. Far too much time is devoted to topics like philosophy of education and social issues, too little to things like subject knowledge, normal and abnormal language acquisition, how to teach reading, and so forth. For example, I know of teacher education programs in which teachers, including those destine to be elementary school teachers, are not taught how to teach children to read, which is probably the single most important thing they do. In one case, as part of a seminar, the students read and discussed two papers on approaches to the teaching of reading; that was the entire extent of their training in how to teach reading! (b) excessive diversity of students is very difficult for a teacher to deal with. You only have the time and resources to individualize instruction so much. If the students are at very different levels, even a good teacher can't do a good job. The mainstreaming of students with disabilities has exacerbated this problem. I don't mean to suggest a return to rigid tracking or to dumping all special needs kids in separate classes or schools, but we need some combination of classes that are more homogeneous as to level and ability together with adequate support (in the form of teachers' aides and other resources) for special needs students. (c) school administrations and government departments of education often impose poor curricula and materials. Greater competence and less political interference in the education bureaucracy would be a boon.

Comment Re:Violation of ECHR (Score 1) 324

Actually, freedom of speech is intended to protect people who, by their speech, upset other people. Otherwise virtually any expression of an unpopular view could be prosecuted since somebody would be upset by it. The Holy Thursday and Good Friday liturgies of the Greek Orthodox Church to this day ascribe to Jews such as myself the guilt for the death of Christ. Naturally, we find this upsetting. Do you think that the Greek Orthodox Church and its priests should be prosecuted? That is why in countries with strong protection for freedom of expression there are strict limitations on the ability to retaliate for speech, e.g. requiring that defamation be objectively false in order to be actionable.
