* 7366Kartik Agaram2020-12-201-22/+24
| | | | | | Move more padding around. Reading a sector from disk requires about 24 bytes of code.

| | | | | Kinda brutal way to lose the bochs warning. Should suffice for now. As we add more code we'll introduce more sectors.
* 7362Kartik Agaram2020-12-201-2/+2
| | | | | I hadn't noticed that bochs was getting into a reset loop after executing my code correctly. Fix that.
* 7361Kartik Agaram2020-12-201-2/+2
| | | | | Switch bochs from floppy to hard disk. Bochs throws a new warning, but otherwise 32bit.hex continues to work.
* 7360Kartik Agaram2020-12-201-13/+21
| | | | | Insert padding in a few places so we don't have to recalculate addresses quite so much.

* 7358Kartik Agaram2020-12-202-0/+208
| | | | | | | Snapshot: first draft of a boot image that switches to 32-bit mode as quickly as possible (~70 bytes) Doesn't work yet. Gets stuck in an infinite reset loop.

* 7355 - learning to boot into 32-bit modeKartik Agaram2020-12-1910-0/+351
| | | | | | These exercises are from the incomplete "Writing a simple operating system from scratch" by Nick Blundell. https://www.cs.bham.ac.uk/~exr/lectures/opsys/10_11/lectures/os-dev.pdf

* 7341 - tile: function editing doneKartik Agaram2020-12-062-22/+6
| | | | | A tiny modicum of reuse amidst all this copypasta: I'm able to reuse the same function that renders lines without stacks in the sandbox.
* 7340 - tile: function editing almost doneKartik Agaram2020-12-062-4/+215
| | | | | Still a bug in cursor positioning. It's always shown at the start of the function body.
* 7339 - tile: position cursor in correct functionKartik Agaram2020-12-062-8/+77
| | | | Still can't edit functions, but we're getting there.
* 7338 - tile: architecture starting to crystallizeKartik Agaram2020-12-052-21/+54
| | | | | | | | | In particular, I'm starting to have opinions about how to scalably position the cursor at the end of each frame. One advantage of text mode without a pointer device (mouse/trackpad): only one cursor to track. UI can't be modified anywhere. That simplifies any reactive UI framework.
* 7337 - tile: jumping to a functionKartik Agaram2020-12-052-20/+149
| | | | We can't yet edit the function once we jump to it.

* 7332 - advent day 4 doneKartik Agaram2020-12-041-4/+124
| | | | | The code is shit and I can't be arsed to clean it up. But it was a useful exercise given the bugs and gaps it caught in Mu.

* 7330 - snapshot: advent day 4 part 2 easy casesKartik Agaram2020-12-041-8/+100
| | | | Now I need to tune the SubX vocabulary.
* 7329 - snapshot: advent day 4 part 2Kartik Agaram2020-12-0416-2/+147
| | | | | | | | | | | | I've found two bugs in SubX libraries: 1. next-word had an out-of-bounds read 2. next-word was skipping comments, because that's what I need during bootstrapping. I've created a new variant called next-raw-word that doesn't skip comments. These really need better names. We're now at the point where 4b.mu has the right structure and returns identical result to 4a.mu.

| | | | Stupid mistake; I missed one slope in the question.

| | | | | Funny story: I got the right answer for part 1 even though I missed the ':' in the line format. But of course that didn't work for part 2.
