Visualizing the RISC-V Instruction Set

Earlier today, I came across the blog post "Visualizing the ARM64 Instruction Set" and got inspired to give it a shot my self.

After hacking together a quick script and fiddling with the bit order and colors for way too long, I managed to create a decent visualization of the RISC-V instruction encoding. You can find my code below.

The following graphics cover the 64-bit part of the RISC-V ISA, including all ratified 64-bit extensions, with opcodes extracted from the riscv/riscv-opcodes repo.

I mapped the opcodes to 2D coordinates with a Morton space-filling curve.

An opinionated list of excellent Clojure learning materials

These resources (articles, books, and videos) are useful when you're starting to learn the language, or when you're learning a specific part of the language. This an opinionated list, no doubt. I've compiled this list from writing and teaching Clojure over the last 10 years.

• 🔴 Mandatory (for both beginners and intermediates)
• 🟩 For beginners
• 🟨 For intermediates

Selling Lisp by the Pound

“Paper late!” cried a voice in the crowd,

“Old man dies!” The note he left was signed,

‘Old Kiczales’ - it seems he’s drowned!
