Fifth Linkfest

C-c-c-c-combo breaker! Finally the Linkfest deviates from the pattern it was establishing for itself. A Monday linkfest instead of Saturday? How eccentric! The reason the linkfest was delayed was I spent the weekend in Chicago, attending and speaking at the Graduate Student Logic Conference at UIC (if you’re interested, I spoke about Fitch’s Paradox– by the way, the paper I wrote on the subject is now online in the journal “Synthese”, and will appear in print soon, sadly Synthese has a paywall but you can read a bootleg version of the paper here (the bootleg has no author name because Synthese uses double-blind peer review and Synthese’s TOS doesn’t let me alter the final draft)) (the paper assumes basic familiarity with the paradox, so the blog article should be read first, if you don’t already know the paradox)

Here at Xamuel Laboratories, we are constantly researching how to make Linkfests provide more value more efficiently. This time around, we are experimenting with adding new info along with blog article titles, in cases where the title alone gives very little idea what the article is about. Hopefully this will give you a better idea when a link is worth reading, when the blogger didn’t pick a very informative title.

The previous Linkfest is here: Linkfest 4.
