google-authenticator - Two-step verification - Google Project Hosting
10 days ago
The Google Authenticator project includes implementations of one-time passcode generators for several mobile platforms, as well as a pluggable authentication module (PAM). One-time passcodes are generated using open standards developed by the Initiative for Open Authentication (OATH) (which is unrelated to OAuth).
These implementations support the HMAC-Based One-time Password (HOTP) algorithm specified in RFC 4226 and the Time-based One-time Password (TOTP) algorithm specified in RFC 6238.

Leader Election Algorithms
september 2011
In the course of a distributed computation, it is often useful to be able to designate one and only one process as the coordinator of some activity. This selection of a coordinator is known as the "leader election problem" and it has been studied in many contexts.

The Swiss-Knife polynomials
february 2011
The Swiss-Knife polynomials are closely related to the family of Euler-Bernoulli polynomials and numbers. The coefficients of the polynomials are integers, in contrast to the coefficients of the Euler and Bernoulli polynomials, which are rational numbers (see HMF, page 809). Thus the Swiss-Knife polynomials can be computed more easily and applied to special number theory.

Libcpu
june 2010
"libcpu" is an open source library that emulates several CPU architectures, allowing itself to be used as the CPU core for different kinds of emulator projects. It uses its own frontends for the different CPU types, and uses LLVM for the backend. libcpu is supposed to be able to do user mode and system emulation, and dynamic as well as static recompilation.

Regular Expression Matching Can Be Simple And Fast
march 2010
This is a tale of two approaches to regular expression matching. One of them is in widespread use in the standard interpreters for many languages, including Perl. The other is used only in a few places, notably most implementations of awk and grep. The two approaches have wildly different performance characteristics
