Upcoming events

Next Scheduled Event

Tuesday, July 29th.
18.30–20.30 (approximately)
Location:, 1017CE, Herengracht 597 (Google Map), Bejing Room.
  1. Yves Orton (demerphq) :: Breaking Perls Old Hash Function

    Yves will talk about the hash randomization in the perl core, or phrased differently: Key Discovery Attack on Bob Jenkins One-At-A-Time Hash (as used in earlier perls).

    Yves will explain the mechanism, the weakness, and how it was solved in modern versions of the perl interpreter.

  2. Abigail :: Releasing perl

    For many years, perl releases were infrequent, with a single person (the "pumpking") responsible for several subsequent releases.

    This has changed in the last years, and perl is released on a frequent schedule, with many people ("release managers") taking turns and making a release of perl. In this talk, we will look at what it takes to make a perl release, and show that "everyone" is able to become a release manager.

    Abigail can speak from personal experiences, having released perl twice before. Abigail is also the acting release manager, and will do a release at the end of July 2014.
