Welcome to ColinFinck.de!

This is the single place where I collect my adventures into ReactOS, Rust, and low-level system software, write about them, and release some tools from time to time.
Hope you find something useful here :)

Talking at EuroRust about my Windows Linked List crate

I recently attended the first ever EuroRust in Berlin from 13th to 14th October. I have been eagerly looking for such a dedicated European conference on Rust, but my previous Google searches were all in vain - and always ended up here. Glad that’s no longer the case :) At EuroRust, I had the opportunity to speak …

Releasing the S7-Project-Explorer as open-source

After the ENLYZE PortSniffer in 2020, I’m glad to announce that another tool I developed at ENLYZE has just been released as open-source. The ENLYZE S7-Project-Explorer is a Windows application to explore Siemens STEP 7 projects and export a complete PLC variable list as a CSV table. This solves our recurring …

nt-list: Windows Linked Lists in idiomatic Rust

On my quest to develop a ReactOS/Windows bootloader in Rust, I inevitably had to stumble upon the infamous LIST_ENTRY structure used in the LOADER_PARAMETER_BLOCK. This is what Windows, Windows drivers, and components influenced by Windows (e.g. UEFI) have been using for a long time to uniformly handle linked lists. I …

I had the honor of speaking about my recent NTFS Rust filesystem crate and the video is now online: Slides are available here. Thanks a lot to all volunteers for …

It’s also the next building block on my mission to write a ReactOS/Windows bootloader in Rust. ntfs is a Rust library that implements the low-level structures of the NTFS …

That time I had to patch the Universal CRT

I just finished a blog post where I replaced almost the entire Microsoft build toolchain for our Windows software with open-source alternatives better suiting our needs. Except for the Visual Studio C runtime library, nowadays called Universal CRT (shortened to UCRT or just CRT). The CRT had been performing without any …

Relaunched my website!

I finally got the mood to do what was long overdue and recreate my website from the ground up. People who visited ColinFinck.de within the past decade must have had the impression that I vanished without a trace. Whereas in reality, I had just been extremely busy with ReactOS, Rust, and my daily job at ENLYZE. There …

Modern Visual Studio meets ancient Windows

In my previous blog series, I have shown how to write Win32 applications in 2020 using the amenities that modern C++ brings. Writing an application in 2020 doesn’t mean that we have to forget about 2000 though: The unrivaled compatibility of the Win32 API makes it possible to run your modern application even on …

nt-hive: A Rust crate for parsing Windows registry hive files

I have embraced the Rust programming language since my unikernel thesis 3 years ago, and at my daily job at ENLYZE I get to use it everyday for implementing parsers for machine protocols. What had been missing so far was a Rust project that combines my passions for Rust and ReactOS. Aiming to fix this, I’m …
