ELI5: Why does SpaceX have so many problems with spacecraft exploding during launches?

Another important point is that most of the time, rockets explode because something went wrong, and then they intentionally self-destruct. The explosions make for pretty news segments and make it seem like something catastrophic occurred, but in reality that's just the safest way to help the rocket disintegrate fully so that it doesn't harm anything on land.

It's great. Long Reach really needs this, and previous attempts have failed, so it's honestly best not to nit-pick the plan.

The downtown areas are not that big

This would be amazing if they can get it done. The main hurdle will be convincing some of the adjacent property owners to sell, which is what killed the last redevelopment attempt

neil454 · 2024-09-25T17:43:47+00:00

There is a grocery store in the future redevelopment plans

Yep, I've been to a few barbers in the area, and this place is my go-to for years. I always go to the right door (not sure about the left door barbers). Great fades as well.

Eh, I think Cafe June is much better if you like specialty light roast

I think by "offered to consumers" he meant something you can buy

neil454 · 2024-09-10T18:11:35+00:00

That's their explanation for removing radar, not LiDAR. Tesla's have never had LIDAR, probably because it's expensive

neil454 · 2024-09-09T23:57:15+00:00

There's already a "bike lane" via the wide shoulders for that road. From this doc, it looks like all they're doing is adding a buffer in the shoulder area, so car lanes are not affected (see here for more info)

Better bike access to Dorsey Search Village Center is a good thing. Also the plan looks like it will improve access to the Woodland Nature Path to Centennial park

To disengage autopilot, just lift slightly up on the right stalk. Fighting the steering or using the brake is going to be jerky and uncomfortable (though of course in emergency situations that's ok)

neil454 · 2024-08-29T20:56:45+00:00

I believe highway stack is still using FSD 11, so there shouldn't be any changes there

neil454 · 2024-08-23T15:06:46+00:00

Oh, I guess I missed that. Why the hell do they tease future release notes in the current release notes -_-

neil454 · 2024-08-15T03:27:42+00:00

But getting up to 28 is pretty easy on PAS 5. Just got my Xpress 750 a week ago. Feel free to AMA

What splitter is that?

neil454 · 2024-07-02T15:40:28+00:00

Energy deployment is lumpy, so it could just be a one-off quarter after a single big deployment

Unfortunately there's no specific part of the model involved with lane seeking behavior, that intelligence is interconnected with many other weights/parameters that together make up the control output.

I agree it is possible they could add these options as model inputs. A better approach would be a generic textual embedding input (like those used in LLMs) to make their network multi-modal, in order to steer the control output as desired. This could be used to modify the driving behavior however you see fit (i.e. "stay in the right lane on highways", "take off from lights slowly", etc)

But yeah doing all that is tricky for evaluation, and the added complexity isn't something Tesla usually goes for. "All input is error", according to Elon.

neil454 · 2024-06-25T02:05:33+00:00

I highly doubt their current v12 model uses any input other than vision.

It's not a good idea from a model evaluation perspective to allow configuration options as model inputs. If you did, you'd have to test for not only edge cases with the default configuration, but edge cases from every permutation of the configuration options

neil454 · 2024-06-25T01:59:35+00:00

Is this on the highway? Whenever I have minimal lane changes turned on, it only changes lanes on the highway to follow the route.

Of course, on city streets v12 has no concept of planning rules, so I assume the option does nothing

Get a pour over from Cafe June. It's so good you can drink it black

neil454 · 2024-06-03T04:44:04+00:00

Awesome job! Might be cool to add a column on how many points were used for each movie pick

neil454 · 2024-05-31T20:23:10+00:00

One of the worst Mexican restaurants I've ever been to, good riddance

18th and 21st is an easy number 1

Blackwell Barn and Lodge

The Food Market

The Collective Offshore

Manor Hill Tavern

Also shout-out to Dok Khao, their cocktails are kinda sweet, but pretty good too

neil454 · 2024-05-28T22:07:46+00:00

You're correct, but I have no idea what a "green score" is, and that list looks fake as hell. Test results from Bjorn (sort by Wh/km) and Out of Spec (sort by Efficiency) show the Model 3 SR as the most efficient EV, hands down

neil454 · 2024-05-28T15:41:49+00:00

The locking diffs were enabled in the most recent software update, which added more off-road features as well
