Efficiently reading a CSV of floats in Rust
In hpstat, we are often required to read large CSV files consisting of a header of string column names, followed by data consisting entirely of floating-point numbers. Profiling reveals that a naïve approach based on generic CSV parsers is inefficient at this task.

Constructing a working copy of SCORE 4 – software preservation
SCORE is a historical music engraving program written by Professor Leland Smith and developed from 1987 to 2002. It was known for its high-quality results compared to other software available at the time, and its output inspired the Leland music font developed for MuseScore. The… »

A high-performance Rust implementation of the Turnbull non-parametric maximum likelihood estimator for interval-censored survival data
A common need in biostatistics is to estimate survival curves, but particular difficulty arises when observations are interval censored, i.e. the time of event is not observed exactly, but is known only to fall within a particular interval. In this setting, Turnbull estimator [1] extends… »

Extracting TOTP keys from a proprietary Android 2FA app
This is an analysis of an early 2010s proprietary Android-based two-factor authentication (2FA) application for a particular cloud service provider – à la Okta, or Microsoft Authenticator. This particular cloud service has been publicly criticised for not supporting industry standard 2FA algorithms such as time-based… »

A high-performance Rust implementation of interval-censored Cox regression
Cox proportional hazards models are commonly used in biostatistics for the modelling of time-to-event data, such as mortality or disease progression. A difficulty in applying Cox models arises when observations are interval censored, i.e. the time of event is not observed exactly, but is known… »
