Dart really has unique mechanisms, which make its reverse engineering difficult. I've written a new blog post on how byte arrays are written in assembly.
I think it's the first language I see which generates such custom assembly...?

Yesterday I got a huge donation of from a guy who had programmed and since the 1980s until his death this spring. A big project of him was altering and extending Simons' BASIC for the C64. There are plenty of sheets with hand-commented disassemblys and self-programmed routines.

I've published a blog post on reverse engineering Dart. This is the programming language used by Flutter.

This is a specific point on a non-standard way Dart assembly performs routine calls. It explains why decompilers just don't get it right when it comes to Dart...

is not only a modern tv series.

It started with a movie in 1973 and a book in 1974, both by Michael Crichton.

The original movie seem to have glimpses of code pretending to be the robots' programming.

The code looks like actually some digital movie/animation production software! in 1973!

Does anyone recognize what assembly flavor, what CPU might it have been?

I just started to learn Assembly today.
Yup. hurray me.
It's a very refreshing view on programming after only using high level languages like Python or shell languages.

I kinda want to love this language, but she's making it hard.

Assembly theory takes a knack at defining time as a property of complex objects that exhibit forms of memory.

This does not look like much, but my operating system is now able to do console I/O via a character device:

  • A device manager registers available devices
  • stdio init calls open on the console device, which allocates a file structure and returns a file descriptor,
  • then console_puts calls write() on the returned file descriptor to emit the string.

The calling convention makes maximum use of registers and is not that bad.

All of this was written in hc11 .

I’m starting a new project to learn about linkers. It’s called ˋweld`, and it lives here https://github.com/Hywan/weld.

I do this on my free time; understand very sporadically.

This toot is a thread to show progress or to ask help.

ˋweld-object is now able to disassemble x86 instructions when debugging an object file (with the ˋdebug-x86 feature turned on), https://github.com/Hywan/weld/commit/043e16d731108ac1a7cade05de209a18e0591959.

It’s really handy :-)!

It’s based on the excellent iced-x86 crate, https://github.com/icedland/iced.
