It challenges Neumann's computer architecture in absolutely all possible and known fronts. It also helped me refresh knowledge about electronic signaling specs of various components. #computer #security #lowlevel #hardware #software

It uses Interrupt-based System Calls to execute Kernel Mode (Ring 0) functions within the OS Kernel. #osdev #intel #assembler #linux #lowlevel

620 followers · 2402 posts · Server linuxrocks.online4 years using and championing the #fediverse full time and I've never written a #introductions toot. Well, or I have and can't find it.
I'm a #blind guy from 🇬🇧 with a passion for #technology and #programming, particularly #lowLevel #systemsProgramming in #C, #C++, #Rust, etc.
I've been a huge #freeSoftware / #openSource advocate for the majority of my life. I run #Linux and I love open, #decentralised technologies like #ActivityPub, #Matrix, #bitTorrent etc.
In my view, technology is built to make our lives easier, and in many ways, it isn't these days. It is truly my opinion that the only way #tech can be sustainable is if it's built using #FOSS, and does not give ultimate control to any 1 entity, individual or corporate. If technology is to help the people, it must be built *for* the people.
Currently working on https://odilia.app, various projects with the rest of the Lower Elements gang at https://lowerelements.club, and a Computing Science BSC at the #University of #stirling

The first picture represents the #C code for implementing a #virtualmachine for the LC3 architecture. It's less than 125 LoC.
The second picture is bytecode that works on the Virtual Machine and cam sum two numbers read from the keyboard.
C is beautifully simple. And the code is a little too cryptic.

233 followers · 794 posts · Server fosstodon.orgRecently I wanted to implement a snake game using only the smallest amount of memory possible.
In the end I've come up with a solution (using #C and #curses) that is (re)using only 4 int variables.
After the #macros expand the #code looks rewardingly crazy.

The battery is the Shepard.
The surface charge are the sheep dogs.
And the electrons are the sheep, led along by the barking dogs.
That's how electricity works.
So we're not getting single threaded CPU processing any faster unless we can find a way to make faster sheep.

122 followers · 259 posts · Server fosstodon.orgLast year I've decided to write an article about how we can write a working register-based #virtualmachine in 125 lines of #c code.
In the end it was a little "bit" less.
