You mean you operate them like Microsoft's failed submerged data center project [1]. When pointing at validating past examples you are generally supposed to point at successes.

The opposite of down is up, so it wouldn't be completely illogical.

17 mph is pretty slow unless it’s a school zone
dcanelhas · 11 days ago
Indeed, 15 or 25 mph (24 or 40 km/h) are the speed limits in school zones (when in effect) in CA, for reference. But depending on the general movement and density and category of pedestrians around the road it could be practically reckless to drive that fast (or slow).

From the Waymo blog...

> the pedestrian suddenly entered the roadway from behind a tall SUV, moving directly into our vehicle's path. Our technology immediately detected the individual as soon as they began to emerge from behind the stopped vehicle. The Waymo Driver braked hard, reducing speed from approximately 17 mph to under 6 mph before contact was made.

> Following contact, the pedestrian stood up immediately, walked to the sidewalk, and we called 911. The vehicle remained stopped, moved to the side of the road, and stayed there until law enforcement cleared the vehicle to leave the scene.

> Following the event, we voluntarily contacted the National Highway Traffic Safety Administration (NHTSA) that same day.

I honestly cannot imagine a better outcome or handling of the situation.

It does sound like a good outcome for automation. Though I suppose an investigation into the matter would arguably have to look at whether a competent human driver would be driving at 17mph (27km/h) under those circumstances to begin with, rather than just comparing the relative reaction speeds, taking the hazardous situation for granted.

What I would like to see is a full-scale vehicle simulator where humans are tested against virtual scenarios that faithfully recreate autonomous driving accidents to see how "most people" would have acted in the minutes leading up to the event as well as the accident itself

I don't see how it could even have any measurable torque.

You could improve it by making the cylinders have sticky-out bits that would scoosh the fluid around better, like little paddle wheels, and if you wanted to get some serious torque transfer you'd push the two paddle wheels so close together that the paddles actually kind of intersect.

Indeed, then this design will truly have come full circle.

There's also Julia.

Earlier in my career, I found that my employers would often not buy Matlab licenses, or would make everyone share even when it was a resource needed daily by everyone. Not having access to the closed-source, proprietary tool hurt my ability to be effective. So I started doing my "whiteboard coding" in Julia and still do.

I remember the pitch for Julia early on being matlab-like syntax, C-like performance. When I've heard Julia mentioned more recently, the main feature that gets highlighted is multiple-dispatch.

I think it seems pretty interesting.

Claude is not very good at using screenshots. The model may technically be multi-modal, but its strength is clearly in reading text. I'm not surprised it failed here.

Even with text, parsing content in 2D seems to be a challenge for every LLM I have interacted with. Try getting a chatbot to make an ascii-art circle with a specific radius and you'll see what I mean.

Selfish how, because he clearly does not say that upgradability or customizability are bad things? Its also not like hes proposing something that isnt reality for most manufacturers, especially Apple.
dcanelhas · 2 months ago
I think the selfishness here is related to being fine with generating a pile of electronic waste that becomes a problem for everyone else, as long as he can avoid carrying a few ounces extra.

It's hard to recycle electronics, because separating materials that are chemically bonded together is very labor intensive and isn't worth it from the price of aluminum, copper, lithium, etc alone.

It would have to cost more to dispose of a laptop for this to work out financially.

I wish there was an active dev community that could patch win10 going forward, but without access to source code for the kernel, perhaps that isn't really viable.

Ideally I would want to use Linux but I also want to play games that are only supported on windows.

Does using WSL help or is an outdated windows base still going to be the weakest link in the security onion?

It's an interesting read. I guess the difference between this situation and the ideal case is that he would have been admitted for observation as a precaution in a world where there was plenty of room and staff to take care of even the less obvious emergency cases.

Even in a very well functioning system similar cases might happen eventually, anyway (but at a much lower frequency). ROC plots come to mind.
