2/ Gerry Sussman. Hofstadter said Gödel invented LISP in proving the incompleteness theorem. Sussman shows the amazing breadth and elegance of LISP ideas. SICP, SICM, How to build robust systems. google.com/url?sa=t&rct=j…
3/ Eric Drexler. Engineering is neglected by philosophy departments (see Sussman also). Engines, Nanosystems, how engineering differs from science, CAIS. Disclosure: he's currently at the FHI (which is part of a phil dept). overcomingbias.com/2013/06/drexle… lesswrong.com/posts/x3fNwSe5…
1/ Why did Wikipedia succeed when 7 similar online encyclopedia projects (mostly started around the same time) all failed? This cool paper investigates and gives surprising answers...
2/ Did Wiki have the most technical talent? No, they had the *least* technical founders by far. One failed project was led by Aaron Swartz (RSS + Reddit creator) and one by the founder of Slashdot. Wiki's initial software was off-the-shelf.
3/ Wiki's 1st source of success: a familiar end-product. Use a novel mechanism (online collaboration) to produce a trad encyclopedia. Some failed projects aimed for new kind of encyclopedia for internet age and this confused contributors.
1/ Thread for exciting philosophy being done outside university philosophy departments. Descartes, Hobbes, Hume, Mill, Frege, Ramsey, and Turing all worked outside phil academia. Here are some contemporary examples...
2/ David Deutsch: foundations of Quantum computation, Many Worlds, Fabric of Reality, Beginning of Infinity, Constructor Theory
1. What % of people have natural immunity to Covid? We get some information from closed environments where a large % of people were exposed. Here are some numbers from prisons, a meat plant, and call center. From this, seems that >80% are susceptible under the right conditions.
2. Note that only the Korean call-center number is based on a scientific study. However, the call center was shut down early and so it's likely that >55% would have been infected if it had stayed open. I think >65% is plausible for prisons, but not sure about Marion result.
3. Some hospital wards and care homes also had large %es infected. But older people are more susceptible. Prisons, meat plants and call centers cover a wide range of ages (18-70). In the table I adjust for the false-negative rate of PCR testing, which is ~20-30% for mass testing.
