    Interested in C++17 but not sure how to apply it effectively? At I presented a practical application of generative & declarative techniques: Here's a type-level description of command messages and some C++17 tricks to automate message processing and serialization :)

    I never got around adding support for anything other than this simple demo, and eventually stopped working on GameCube emulation for good. And well, then this happened:

    I made a GameCube emulator! Sort of. Back in 2015 it even beat at VideoInterface emulation - thanks to 's help! A while later, he ended up fixing Dolphin though :) This emu could run pong and, for your retro pleasures, featured emulated deinterlacing 😂

    This homebrew game uses software rendering, purely on the emulated CPU - getting all the edge cases in their algorithms right is a testament to the correctness of any ARM core! A ton of fixes, a full-blown VFP implementation, and 4 weeks later, things look much better 👌

    Dumped from raw memory, rendered via gnuplot, garbled beyond recognition, and yet a major feat: Back in 2016, getting my emulator to produce any picture at all was a true challenge of its own!

    Super excited to share progress on my new emulator soon! 🎉 Having started this project 3 years ago, it's amazing to finally see the pieces come together. Going from nothing to rendering title screens is always the hardest part, so luckily I'm over that now 😄

    : “Teaching Old Compilers New Tricks: Transpiling C++17 to C++11” Love C++17, but can’t use it yet? Tony shows how you can backfill to C++11 - even the language features!

    Does anyone know about attempts of implementing an (algebraic) effect system in C++? Curious to see any prior art in that space!

    Glad to be back in the UK for next week! If you want to discuss why C++ needs monads or learn how physicists hacked duck-typing into electrodynamics, find me in Folkestone :)

    Fallout of me spending 3 days to write ~500 test cases for my current project: I fixed most tests by *removing* 20 lines of code from my implementation. The smell of progress!

    On my way to Leipzig for ! Find me at the Dolphin assembly to chat about emulation, discuss why we need monads in C++, or just to say hi :D

    C++ tip of the day, getting the index of a type within a parameter pack: Fold expressions and constexpr to the rescue!

    C++17 is great, but what if your compiler doesn't support it? In my second talk, I introduced my new tool CFTF: A C++17 to C++11 transpiler, helping your old toolchain understand modern C++ syntax! Source at :)

    Hot code reload? Check! With instant feedback? Sure! And visual input in the editor? Um … yes, of course! This is how my workflow with and looks like now. In pure C++. 😎

    C++ insight of the day: It's tempting to expect the fold expression "(Ints - ... - 5)" to evaluate to -5 for empty parameter packs, but it's actually +5 ...

    I gave a short interview for about a C++ trick used in the serialization code of my emulator! I'm up at 37:41, but I recommend listening to the other parts as well of course :)

    Episode 169 is live! and with a trip report and lightning interviews!

    Just got home from a massive 26 hour travel - certainly was worth it, but I guess I won't be saving on those extra bucks for a better airline next year!
