# Rustload

Rustload is a daemon process that prefetches binary files and shared

libraries from the hard disc to the main memory of the computer system to

achieve faster application startup time. Rustload is adaptive: it monitors

the application that the user runs, and by analyzing this data, predicts

what applications he might run in the near future, and fetches those

binaries and their dependencies into memory.

It builds a Markov-based probabilistic model capturing the correlation

between every two applications on the system. The model is then used to

infer the probability that each application may be started in the near

future. These probabilities are used to choose files to prefetch into the

main memory. Special care is taken to not degrade system performance and

only prefetch when enough resources are available.

## Features

- TODO:

## Usage

- TODO:

## Why a `preload` clone?

- The original code is nowhere near readable.

- It is littered with unnecessary global variables.

- It has virtually no documentation, making it more irritating to use.

- The original implementation uses some arcane shit like Make, Autoconf (idk),

  which I hate with burning passion. In fact, for that exact reason, [I decided

  to rebuild the project with meson.][my-preload]

## Why Rust?

- It is easier to use and understand than C and C++.

- Rust programs are easier to manage.

- I dislike manual `free(...)` after use.

  - I hate unpredictable `SEGFAULT`.

- Rust has cleaner string handling.

- The iterators in Rust are beautiful.

- [C++ is as ugly as a language can get.][torvalds_cpp]

- I like the way Rust's build system works.
