Build your own shell - Codecrafters style

Project 7 of Nand2Tetris is about translating virtual machine 1 (VM) commands for the Hack computer platform to a series of Hack assembly language (asm) instructions. The main focus of this project is determining the sequence of assembly language instructions corresponding to each VM command, given that the programming model of the computer is...

fzf is a general-purpose fuzzy text matching tool at its core that takes in a list of newline-separated text and allows the user to search for something within those lines and select one or more of the lines by typing just a few character sequences into a search field. It is highly customizable and the maintainer seems to have a ... → Continue...

I wrote a two-pass assembler for the Hack assembly language! This is the sixth and final project of the first half (Hardware) of the Nand2Tetris course. In Project 6, the task is to write an assembler for the Hack assembly language. Unlike the previous projects which could only be written using the custom hardware description language (HDL) used...

Continuing from where I left off in my Nand2Tetris journey, I went ahead and completed Projects 4 (Machine Language) and Project 5 (Computer Architecture) and I now have "built" my very own Hack computer from scratch! Follow my progress on Github here: guru-das-s/nand2tetris. Project 4: Machine Language This project introduces the Hack...

I write a lot of notes in Markdown on a daily basis as a sort of personal wiki. Almost all of them contain code snippets - shell commands, mostly. Today I learnt that there is a much better way to directly execute a shell command listed on its own in a single line in vim. Two ways, in fact. The first ... → Continue reading
