  • mpsolve - Multiprecision Polynomial SOLVEr
    Software that aims to provide an easy to use (hopefully) universal blackbox for solving polynomials and secular equations.

    Among its features you can find:
    - Arbitrary precision approximation.
    - Guaranteed inclusion radii for the results.
    - Exploiting of polynomial structures: it can take advantage of sparsity as well as coefficients in a particular domain (i.e. integers or rationals).

    It can be specialized for specific classes of polynomials. As an example, see the roots of the Mandelbrot polynomial of degree 2.097.151 computed in about 10 days on a dual Xeon server.

    If you use MPSolve in your research, please cite it as follows:

  • Valgrind is an instrumentation framework for building dynamic analysis tools.
    There are Valgrind tools that can automatically detect many memory management and threading bugs, and profile your programs in detail. You can also use Valgrind to build new tools.

  • Monocypher is an easy to use crypto library.
    Small. Sloccount counts under 2000 lines of code, small enough to allow audits. The binaries can be under 50KB, small enough for many embedded targets.
    Easy to deploy. Just add monocypher.c and monocypher.h to your project. They compile as C99 or C++ and are dedicated to the public domain (CC0-1.0, alternatively 2-clause BSD).
    Portable. There are no dependencies, not even on libc.
    Honest. The API is small, consistent, and cannot fail on correct input.
    Direct. The abstractions are minimal. A developer with experience in applied cryptography can be productive in minutes.
    Fast. The primitives are fast to begin with, and performance wasn't needlessly sacrificed. Monocypher holds up pretty well against Libsodium, despite being closer in size to TweetNaCl. (More detailed benchmark)

  • The Amsterdam Compiler Kit
    The Amsterdam Compiler Kit is a cross-platform compiler and toolchain suite that is small, portable, extremely fast, and extremely flexible. It targets a number of low-end machines including the Z80, 8086 and 80386, but there are many other code generators available. It supports several languages, including ANSI C, Pascal and Modula-2, and contains integrated runtime libraries including a libc.

    The maintainer, David Given states "I, dtrg, cannot honestly recommend using the ACK for production code unless as a stop-gap measure or unless the other benefits of the ACK (e.g. having a very lightweight turnkey toolchain is valuable to you) outweigh the code quality."

  • Port of the "Ritchie C compiler" to the TI990 series processors
    This repository contains a port of the "Ritchie C compiler" to the TI990 series processors, in particular the 9995 and 99105 chips. The port is currently fairly complete; only floating point operations remain unported. Other tool chain components (assembler, linker, etc.) are also provided.

    The long term goal is to run ancient unix on these chips. As a first stepping stone on that journey, a port of the original 1983 version of the Xinu system has already been completed. The source for that is also in this repository.

    Interesting software, such as
    unifdef selectively removes C preprocessor conditionals. My version of this program now shipped by all the BSDs (including Mac OS X) and is used by the Linux kernel build system.
    regpg safely stores server secrets using gpg, so you can keep them in version control.
    picoro - tiny coroutine implementations in pure C. I wrote an accompanying article, coroutines in 20 lines of standard C.
    Counting the days - tiny routines for converting Gregorian dates into linear counts, like Julian day numbers or Unix time_t. The date of the count - a small routine for converting linear day counts into Gregorian dates.

  • Javascript 9P/drawterm implementation. Yes, Javascript. (Also some C compiled to WebAssembly)
    WARNING: PROBABLY INSECURE
    This is a version of drawterm (a program for connecting to Plan 9 systems) which runs in a webbrowser. To connect to the remote host, it uses Websockets, which means you need a proxy such as websockify.

    Jsdrawterm is written in Javascript, but it uses a bunch of C libraries from Plan 9 (for crypto and drawing routines) which need to be compiled to Webassembly. Since the Javascript also deals with some of the crypto, it's probably horribly insecure and hackers will steal your cats.
