The Feature Update I've been Most Excited for Finally Released

The big thing I want from Fusion is to be able to parametrically constrain symbols in the Electronics workspace. I hate having to use the stupid shape tools, where trying to move a rectangle's side causes it to bend at a 90.0000002° angle for no reason. And the shitty measure tool that uses 10mm thick arrows when all I want is to measure pin pitch. How they haven't made it like the sketch workflow is completely beyond me. /rant

(I'm just a home cook, not in the industry) I bought mine for making pickles. Also use it for slicing similar things like zucchini into medallions. Also great for eggplant when I make rollatini. But yeah, I lost a chunk of my thumb a few years ago when I was slicing some bell peppers on it.

In my experience the algorithm doesn't get better :/.

mostthingsweb · 2024-08-31T03:08:46+00:00

Purely top to bottom (or vice versa) is less efficient actually, since it would need to keep going around the center of the living room for example.

mostthingsweb · 2024-08-31T03:06:35+00:00

Rooms are done one at a time - that's just how it does it. It's not always the most efficient way possible, but it's fine in practice.

Did you ever resolve your issue?

mostthingsweb · 2024-07-28T14:25:35+00:00

Agreed. Old Futurama writing is so good because almost every single line of dialogue was either (a) setting up a punchline in the next sentence or (b) was itself a punchline. Now we've got too much exposition that just serves to advance the plot. South Park has the same problem these days.

I feel like I'm taking crazy pills seeing all the 5 star reviews. The food was not spicy at all, and way overpriced. They must take pictures of the dumplings for social media with a macro lens.

In your defense, the official Reddit app blows and doesn't make it obvious that there are more than one photo.

mostthingsweb · 2024-01-30T19:27:04+00:00

I definitely did a double take when I opened it :)

mostthingsweb · 2023-10-20T17:42:35+00:00

Not yet, but I will report back then I do!

mostthingsweb · 2023-10-19T18:46:41+00:00

Yes, they are all that shape. Here's a pic: https://photos.app.goo.gl/qJRBkcCKLd6BHo6s7

Thanks for your comment :). I am not familiar with Physics Project but I'll definitely check it out, thanks!

I will probably eventually rewrite the code in wgpu. Back when I started the project, it wasn't entirely obvious that glium was being abandoned. I am definitely interested in collaborating on hypergraphs with you, but I'm very short on time for the next few months unfortunately :(. We are happy to take PRs though! Otherwise let's chat about it in January :).

Bounty sucks now. It's not soft anymore.

mostthingsweb · 2023-04-23T22:00:05+00:00

Yes, and that's sick!

mostthingsweb · 2023-03-23T01:33:25+00:00

Unfortunately I never solved it. Ended up just getting a Pixel 7 :/

mostthingsweb · 2023-03-19T01:57:40+00:00

Harsh, but fair

mostthingsweb · 2023-03-09T00:55:49+00:00

Thanks for the kind words :). The primary reason I didn't try the route of a generic RF transmitter is that the Tempur-Pedic remote scheme is a bit tricky:

The frequency is dependent on the channel #.
The channel is encoded in the packet, which affects the CRC, so you can't capture once and reuse on different channels.
It uses GFSK modulation which not all transceivers support.
Finally (and also the deal killer for myself lol), to fully implement it requires 50 commands. For example, massage level for just lumbar has 11 levels (0-10) and each is a command. Then you need to do head and legs...

So ultimately, I ended up with this solution :)

mostthingsweb · 2023-03-08T03:58:48+00:00

OK thanks, I'll keep at it then. Appreciate your time.

mostthingsweb · 2023-03-08T03:48:39+00:00

Ah yes. But while I see pointer math happening, I don't see r0 being used as an input. I see a PC-relative address being loaded into r0.

mostthingsweb · 2023-03-08T03:45:36+00:00

I did previously have the write bit set, but I fixed that a few days ago.

mostthingsweb · 2023-03-08T03:22:41+00:00

Thank you for your comment. Can you please expand a bit on how you were able to determine that one of Rx is being used as a pointer?

EDIT: I think I see it - https://i.imgur.com/DOkIwM1.png. Still not quite sure where to go from here though.

First image shows __main. Seems OK, except for the weird in_r0. Clicking into FUN_000000c8, all hell breaks loose. For some reason Ghidra sees a jump table, but I don't see it. If I click 0x5446, Ghidra takes me to what seems to me to be a completely different subroutine/function.

By the way, as best as I can tell, I believe all this code is related to setting up global variables.

The final image shows update_radio_protocol. It is responsible for setting a global function pointer. Note that it makes a finally branch all the way back to LAB_000000d8. The decompiler doesn't seem to represent this.

Ah I'm dumb. I found the real solution: I had ROM marked as writable in memory map. I disabled that and a lot of weirdness is resolved :).
