Culture of Theoretical Computer Science (highly subjective and incomplete) Professional Organizations IEEE (Institute of Electrical and Electronics Engineers) -- general CS and EE, not just theory ACM (Association for Computing Machinery) -- general CS, not just theory, but it sponsors ... SIGACT (Special Interest Group for Algorithms and Computation Theory) SIAM (Society for Industrial and Applied Mathematics) -- general applied math, including theoretical CS EATCS (European Association for Theoretical Computer Science) Major Conferences primarily USA FOCS (IEEE Symposium on the Foundations of Computer Science) -- annual, during the fall STOC (ACM Symposium on the Theory of Computing) -- annual, during the spring LICS (Logic in Computer Science) -- annual SODA (ACM Symposium on Discrete Algorithms) -- annual, usually winter? CCC (IEEE/SIGACT Conference on Computational Complexity) -- annual, usually early summer CRYPTO ( ... Cryptography ...) -- annual, late summer COLT (Conference on Learning Theory) -- annual, winter? POPL (Principles of Programming Languages) -- annual, winter? Europe ICALP (EATCS International Conference on Automata, Languages, and Programming) -- annual, early summer STACS (joint GI/AFCET Symposium on Theoretical Aspects of Computer Science) -- annual, winter, alternates between France and Germany Asia COCOON (Computing and Combinatorics Conference) -- annual, late summer, East Asia FSTTCS (Conference on Foundations of Software Technology and Theoretical Computer Science) -- annual, late fall early winter, India ISAAC (International Symposium on Algorithms and Computation) -- annual, late fall early winter, East Asia Major Journals Journal of the ACM Journal of Symbolic Logic (only sometimes in scope) SIAM Journal on Computing Journal of Computer and System Sciences Information and Computation (formerly Information and Control) Theoretical Computer Science Theory of Computing Systems (formerly Mathematical Systems Theory) Information Processing Letters Notes FOCS and STOC are the two premier conferences in general TCS. They are more or less interchangeable. JACM and JSL are highly prestigious, premium journals. The next four are top-tier and more or less equivalent. The last two are second-tier. Internet Resources TheoryNet is an email list that disseminates generally useful information to TCS practitioners, including conference calls-for-papers, special journal issues and new journals, job postings, etc. I recommend joining this list if you're serious. Go to http://listserv.nodak.edu/archives/theorynt.html to sign up. USC has a subscription to the ACM Digital Library, from which almost all its journals and proceedings are available. There are some electronic archives containing unrefereed TCS papers that are "hot off the press": ECCC (Electronic Colloquium on Computational Complexity) http://eccc.uni-trier.de/eccc/ E-print Archive (Includes subjects other than CS) http://arxiv.org/ -- I hang out at cs.CC and quant-ph Some blogs (an extremely biased sample; all these guys have links to each other; suggestions are welcome) http://weblog.fortnow.com -- by Lance Fortnow, an established complexity theorist at the University of Chicago (favorite theorems, conference news, academic politics, career advice, etc.) http://geomblog.blogspot.com/ -- by Suresh Venkatasubramanian at AT&T labs (TCS with emphasis on computational geometry) http://3dpancakes.typepad.com/ernie/ -- by Jeff Erickson (theory, computational geometry) http://www.scottaaronson.com/blog/ -- by Scott Aaronson, a post-doc at Waterloo (quantum computing, complexity theory, existential and cosm(ic|ological) ruminations) http://dabacon.org/pontiff/ -- by Dave Bacon (quantum information and computing) http://www.qinfo.org/people/nielsen/blog/ -- by Michael Nielsen (quantum physics, including quantum information) The Complexity Zoo (http://qwiki.caltech.edu/wiki/Complexity_Zoo) is a reasonably successful attempt at cataloguing all complexity classes ever studied.
