Joseph Myers Joseph Myers Information on contacting me. Software I maintain or maintained: GCC, glibc, GNU toolchain and C standards development (active), matholymp (active), bsd-games (inactive since 2005, others may have newer versions), nppt (inactive since 2004). My publications and preprints. My mathematics. I have been involved in some manner in Mathematical Olympiad activities since 1992. I am the current maintainer of the web site for the British Mathematical Olympiad Subtrust (BMOS) and Committee (BMOC), and am a member of BMOC and BMOS. I maintain the web site for the European Girls’ Mathematical Olympiad (and do associated EGMO IT work), and that for EGMO 2012, and was a member of the organising committee of EGMO 2012, which was held in Cambridge in April 2012. I maintain the UK IMO Register, a listing of the details of past UK team members in the International Mathematical Olympiad (including both Cambridge’s 1998 Fields Medalists). I am or have been involved in some Cambridge student societies, and for some of these have made relevant documents available online: As Eureka Online Editor for the Archimedeans (Cambridge University Mathematical Society), I made the first parts of Eureka Online available. As Archivist for the Archimedeans, I have made old versions of the Constitution, Standing Orders and Procedures available. I am a member of the Trinity Mathematical Society, and updated and made available online Paul Taylor’s list of past Trinity Mathematical Society meetings (older talks list also available). I am a member of CUAS (Cambridge University Astronomical Society); I have never held any office in that society but have occasionally used the telescopes and have made available here information on the history of the Northumberland Telescope. I’ve done a fair amount of work on the CUCPS (Cambridge University Computer Preservation Society) web site, in particular the information about TITAN. Note that CUCPS is no longer active. Historical information on British Summer Time. As part of my interest in computer history, I have also made available here the standard ECMA-10—ECMA standard for Data Interchange on Punched Tape. The standards organisation ECMA produce computer-related standards that are freely available both online and in printed form (even a complete set of current printed ECMA standards is free); unfortunately they cannot supply copies of obsolete standards such as this one, but since their standards are not copyright it can be distributed here. Many ECMA standards are essentially identical to expensive ISO ones; there are several ISO standards for punched paper tape (numbers 1113, 1154, 1729, 2195 and 3692) but I have not checked their equivalence to this one.
