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… »
Implementing a BLT parser by hand in Rust (vs pest and combine): OpenTally dev log
OpenTally is open-source software which can count single transferable vote elections specified using the BLT file format.
Earlier this month, I replaced OpenTally's previous naive string-manipulation-based BLT parser with one using pest. A new parser was necessary to support extensions to the BLT… »
Asyncify with vanilla JS/WebAssembly (wasm-bindgen compatible)
WebAssembly is a technology for executing compiled programs in the web browser at near-native speeds. However, it has a number of current limitations, including that it does not support coroutines/asynchronicity.
In OpenTally, WebAssembly is used to run code for counting an election. This… »
Reducing binary size with DIY dynamic dispatch: OpenTally dev log
OpenTally is open source software for the counting of preferential voting elections. One feature of OpenTally is support for various different representations of numbers, from floating-point arithmetic through to exact rational representations.
In OpenTally, these are implemented using generics. For example, consider the following… »
Porting Python to Rust/WebAssembly: OpenTally dev log
Background and motivation
pyRCV2 is software for open-source election counting. It is intended to be usable across multiple platforms – as a web application, for the convenience of users less technologically inclined, and as a standalone CLI desktop application, for better performance. To this end,… »
