very real flying rule

Reply in thread

The plan is apparently to sell 4 versions going from none of the silly features to all of the silly features (basic -> suction -> forward thrust -> flying iirc) (with the flying configuration being restricted to invite-only). So the stunts with the flying version will probably drive the sales of the versions that will actually get sold in a meaningful quantity. Although from what I've heard it seems unlikely to me that any of the additional features will be allowed to be used on roads. (Apparently the gas gets really cold when fired due to the pressure dropping, to a possibly dangerous degree, and the wind will certainly be a problem for things behind it, as well as being extremely loud. The suction thing is probably going to also going to be quite loud and might have a risk of firing small rocks out the back at high speeds, it also requires a gasket that wears out over time so it can't be used mindlessly)

It might be really good on tracks, since that was apparently a big focus for them (and a current sporty EV with fans for suction is very good on tracks). Then I guess people will want to buy it because of the sportiness for the same reason people normally buy whatever supercars

Tesla in general seems to have lost whatever lead they had in affordable EVs (especially outside of the US where Chinese EVs are allowed to be sold) so maybe they're trying to shift their brand to more premium?

Yeah, they said it's about 1.7 tonnes. They've also shown off the drivetrain, battery pack, etc in separate displays. Idk, I think it probably is pretty similar to what they plan on selling (to a limited number of selected people apparently)

I'm sure all versions of the car aren't ready for real world use and manufacturing or else they would be selling it already

Edit: it doesn't seem like Tesla R&D has done much else in the past 8 years lol. They have a ton of time, money, and manpower and it does not surprise me that they're willing to spend it on cool but stupid stunts

I think this is fake and an AI generated image. The only place I can find this story is on slop YouTube channels (just showing this screenshot), it isn't anywhere else online. The image also isn't anywhere else that the Google image search can find, and this ai detector that seems accurate in my experience finds it suspicious

Microsoft had relatively interesting ideas concerning 3D and VR content, then proceeded to do an extremely mediocre execution, simultaneously dumbing everything down while also making it hard to use, and then proceeded to discontinue their software after almost never touching it again for seven years

I have a Reverb G2 (windows mixed reality headset), it is really a good headset and is still competitive with the Quest 3 in several areas for use on PC. The WMR software itself isn't that bad and I think if it had more care and attention put into it it could genuinely have been great. If they had better home options, user created homes, more customization and the ability to fix things in place so you don't accidentally move them, the ability to add (even just user created) minigames and dynamic objects that stay in the world, and (most importantly) the ability to actually invite other people into the space to play with you and launch into other games. They're Microsoft, they were large enough and early enough that I'm sure they could even have gotten game developers on board with some protocol that automatically brings people you're playing with into a multiplayer session of whatever game you start. I think they were onto something with their home system and could have fleshed the software out into something much better than even the modern competition. Of course it's all discontinued now, the latest version of Windows doesn't even support it, I plan to continue to use the old version until it stops getting security patches in 2026 and then switch to Linux where hopefully the open source people will finally fully support using controllers.

Thank you Ubisoft!

Played through stray for the first time recently

The game was great, especially for how relatively small the team was, but honestly the reveal of the largest mystery in the game was very underwhelming.

It's still a good game though, I do recommend it.

This is Alyssa Rosenzweig. She reverse-engineered Apple's M1 GPU with no public documentation and also developed an open-source Linux driver.

lol I randomly searched for a page from collabora about how they reverse engineer GPU drivers (since I've seen that they've done that for other GPUs) and the very first page I went to was written by this person. Apparently this was a side project while she did fairly similar work on Mali GPUs at Collabora.

Anyways, here's what she said about the process:

Typically, for Linux or Android driver reverse-engineering, a small wrap library will be written to inject into a test application via LD_PRELOAD that hooks key system calls like ioctl and mmap in order to analyze user-kernel interactions. Once the “submit command buffer” call is issued, the library can dump all (mapped) shared memory for offline analysis...

it took some elbow grease to identify the three critical calls: memory allocation, command buffer creation, and command buffer submission...

With those obstacles cleared, we can finally get to the shader binaries, black boxes in themselves. However, the process from here on out is standard: start with the simplest fragment or compute shader possible, make a small change in the input source code, and compare the output binaries. Iterating on this process is tedious but will quickly reveal key structures, including opcode numbers.

From https://alyssarosenzweig.ca/blog/asahi-gpu-part-1.html , there's a lot more details about the subsequent parts of the process in the next articles but they're harder to summarize
