Takerufuji made history
This March we witnessed history of sumo. What Takerufuji did what seemed impossible.
So we’ve got sidetracked…
We’ve got sidetracked, but it doesn’t really matter if we continue forward.
GCC 4.6.4 with RISC-V support
We built GCC 4.6.4 with RISC-V support and C++ and all that in a Debian machine, in a VisionFive board. Here is how.

Guix + Zig + NSIS for the win…DOWS?
How I made a program for Windows and GNU/Linux without touching any Windows machine. The tools and the tricks to be effective (Zig and NSIS for the win).
Bye Protonmail
I left Protonmail. Here is why. I still like them to some degree though.
Mes released and bootstrappable TCC merged
Some merging and releasing has been done. So here we are.
Milestone — MesCC builds TinyCC and fun C errors for everyone
We spent the last months making MesCC able to compile TinyCC and making the result of that compilation able to compile TinyCC. Many cool problems appeared, this is the summary of our work.
More work, more people, more energy — thanks NlNet
Now it’s time to focus on combining all the previous work and making it production ready. NlNet for the rescue, again.
Support Windows not supporting Windows
About the possibility of having Windows users as clients being a software developer that doesn’t use Windows, and how to solve that technically.
Milestone – RISC-V support in Mes’s bootstrappable TinyCC
Bringing RISC-V support to the bootstrappable TinyCC Mes forked. Some problems and a look into the future.
Adding TinyCC to the mix
Discussing what changes need to be done to make GCC compilable form a simpler C compiler, TinyCC.
Milestone — Source to Binary RISC-V support in GCC 4.6.4
Description of the changes applied from a minimal compiler that runs and generates assembly to something that is actually able to compile, interacting with binutils and having a working libgcc.
Milestone — Minimal RISC-V support in GCC 4.6.4
Description of the changes for a minimal RISC-V support in GCC-4.6.4 and how did I reach this point.
