I just completed "Historian Hysteria" - Day 1 - Advent of Code 2024 https://t.co/JNJspq0Pd4 #AdventOfCode

8-bit machine turns out to include Japanese language support out of the box

An informative, albeit dense, video on the difference between VMs and Docker. I learned how Docker works to keep instances isolated and why you'd choose a VM over Docker: https://t.co/74kA334deg

I don't know if it's because I'm still learning Python or because Python doesn't use curly braces, but I find I write smaller functions in Python than JavaScript and tend to abstract code more

[Gregory Garrett @gcgarrett]

Also learned that the element inclusion check runs in O(1) time, which makes sense since the easiest way to implement a set in JavaScript would be to use the elements as keys into an object.

[Gregory Garrett @gcgarrett]

New features coming to JavaScript sets! https://t.co/Yjl5BQrYMS

til that JavaScript's Array `reverse()` function modifies the array it is called on, whereas `toReversed()` will create a reversed copy of the original.

Me debugging an issue in a legacy codebase

[Gregory Garrett @gcgarrett]

Good to know Python can handle 209 digit integers

Implemented a pseudo-random number generator for my 8-bit computer! It generates a 16-bit unsigned integer when you press the button. The generator is a linear-feedback shift register implemented using shifts and XOR, so it's ideal for the 6502 architecture!

[Gregory Garrett @gcgarrett]

8-bit computer, now with RAM!

[Gregory Garrett @gcgarrett]

Making progress...

[Gregory Garrett @gcgarrett]

16 address lines done... now for the 8 data lines 🤪

til I could be building machines to test a mouse's grip strength for a living

Testing the grip strength of mice with a Mecmesin BFG 10N digital force gauge.

[Gregory Garrett @gcgarrett]

One thing I did not anticipate with building a hobby computer was just the amount of wires I'd have to cut and strip...

[Gregory Garrett @gcgarrett]

Yesssssss! https://t.co/eTABsP8zRx

[Gregory Garrett @gcgarrett]

I guess not grounding this 555 timer would explain why it wasn't working...

[Gregory Garrett @gcgarrett]

Quickly finding out that I need a bigger breadboard...

Friday fun coding 6502 assembly! https://t.co/kECVhQWJWG
