My only D in college was my EE101 class at 7:30AM Tuesday and Thursday... and I R a Professional Electrical Engineer. Boy was that a miserable class. I had a few other 7:30AM classes over the years, but most were puff classes that I could do in my sleep. I remember a CAD teacher calling me to wake me up for the final exam because I was a half-hour late but had a perfect score up to that point...
Believe it or not, you can get a command and file compatible alternative to AutoCAD on Linux now called BricsCAD. Haven't tried it on Linux, but have on OSX and Windows.
Yeah... a good solution on the go; VNC in (over ssh) and you are isolated. Ideally have it VPN back to another location to limit the local network concerns. Can power it from a USB power brick for hours.
Plus a minimum of 3% at each end for inverting and rectifying. My point is that you need to include it in how you evaluate a system because you don’t have infinite lossless transmission capacity. Wind turbines in Wyoming would be hard pressed to provide all the power for the Northeast for two days in a storm.
I don’t dispute the findings in concept— just wish that they could have accounted for one of the major holes... or that I could see the information myself to understand the impact.
Shadow operations. Don’t control anything, just observe. If software action deviates from human action, review and analyize. It appears that this is the stage in product development that Uber needs to be in.
Once the shadow driving has advanced to a point where there are no negative deviations in a control environment, define that envelope and test rigorously within the envelope. Continue to shadow outside the envelope and slowly expand the envelope. Within test envelope, thoroughly validate performance with external telemetry— were there any cases where nothing bad happened, but the action taken should have been different.
Aside from the glaring issue regarding Transmission, I was surprised that 12h of storage had as much impact as it did. I had modeled an off-grid location on the leeward side in Hawaii and found I needed 72h of battery for the system to support 90% of the hours in the year with PV only, or 48h with a wind/PV mix.
It would be interesting to see exactly what the production vs consumption map looks like to see what the real impact of transmission losses and capacity would be. As the wind turbines start to exceed 7MW, wind can become a much more stable resource.
Also curious how they established "100%"-- does it build in capacity factors? Peak-day or annualized?
Others mention the length, but also remember that the distribution of digits is not uniform for pass codes-- 0, 1, 2 have the highest rate of occurrence, so if you are brute forcing you emphasize those numbers more. There is a good probability that out of six digits no more than two are 4-9, after you exhaust common keyboard patterns.
That isn't what they said on a tour of spacex back around 2011; I know the Dragon 1 will never fly with people, but it was apparently intended to be the man-rated framework.
As a publicly traded company, Waymo lying would be a bigger offense than a private company. Given the number of years they have been doing this, I would say 5,600 miles might be reasonable. The real issue though is how quickly do they discover new limitations and improve that rate. If each of the interventions they experience now is a one-in-a-million, unique event, then getting to 10,000 miles might be a challenge. I'm not even sure how you address that, as it is about once every couple months for a safety driver; how can that be reliable as a countermeasure.
What about this makes it an edge case? I appreciate most of driving (on a per-mile base) is keeping lane, following the speed limit, and not running into any other cars; and that this part is relatively trivial to manage. Detecting traffic signs/signals is the next increment, and defensive driving follows.
But, saying that a pedestrian at an unmarked crossing is an "edge case" I think belies what driving is.
I will accept a beach ball blowing across a highway as an edge case though.
I can think of a few different kinds of Jaywalking: indifference by walker, convenience to the walker, indifference by planners, and just crossing the street when there is a reasonable break in traffic.
The indifference kind (think San Francisco) is really inexcusable. The convenience kind is a shame, but kind of reality-- going a couple blocks out of your way to cross at a marked intersection rather than an unmarked intersection can be a bit of a pain. In an area where there should be an expectation of walkability, I am happy to give it a pass.
The planning type of indifference -- especially pisses me off though. This is the type of crap that makes it nearly impossible to walk anywhere. I remember a planning commission actually *banning* sidewalks for some insane reason. The same concern holds true if you ignore natural pedestrian routes. If people need to go significantly out of their way, they will either not walk, or they will cross "illegally."
Victim was already crossing the road, in the adjacent lane, as the car approached. The condition was caused by a bad self driving car that should apparently never been on the road.
That the root cause was someone jaywalking doesn't change the fact that jaywalking happens and is a predictable event. It also suggests that the car is inadequately prepared for avoiding hazards. (It also doesn't change the fact that when you don't have crosswalks at reasonable intervals people will improvise.)
Human response time, yes... but that will never address the challenge here. If Uber’s neural network needs more than 0.1s for decision making then it never should have been allowed on the road. Add to that the fact that their initial detection and action window should have been significantly longer with LIDAR ranges, and you appear to have a system that is not road-worthy.
3% volatility today is not a big long-term concern; that can be managed with increased use rather than speculation. The 20% dips are what is a concern, as higher use is unlikely to mitigate those forces, and it will scare people off.
I think your math is off... but mine could be as well. 15 yards would be about 1 second of travel. Assuming 0.1s response time and 1g deceleration the car would have been at ~15mph.
I think we might be the only two people (even here) that would want that. Hell, I'll even take BACnet!
I would also like to know compressor amps and either interval data or cycle time or something to help "smartify" energy consumption. Extra bonus for a register you can write to as a short-term demand response mode.
Viewing the information in a browser isn't the end of the world... just more crap to parse. The idea of the cameras in the fridge makes a few things interesting with a more robust system... but diminishing returns.
I would prefer if my employees didn't speak about salary not because of there being gross inequality, but because the timing often means one person might get a major bump in pay a year before someone else based on what they have done and what we expect them to do in the coming months. I will admit we might sometimes be slow in seeing this in some people (which could be seen as bias), but a real-time balancing of "worth" is completely impractical.
While I don't know how it is in Canada, a public university employee in the US is very much a government employee. While the legislature might not have direct control over their practices and policies, they are very much responsible for funding of the school.
Because of how the tenure system works though, there really aren't many surprises. It is good to know (as an alumni) that certain professors are paid comparably to what they would make in the private sector... even if it means that the law and business school professors are paid absurdly.

Yeah— the headline “expectations” made me laugh— good luck with charging them for failing to meet expectations. Totally irresponsible.

They seem to be using standard muck carts for the waste. I would imagine these are compressed with some cement in them and cured.

Exactly.
The capsule has always been designed as man-rated.

Ok, so forcing them to liquidate might be extreme, but clearly there is some kind of regulatory framework missing here!
I hope the victim has some relatives that want to get rich though.

Might be an issue of resources in Hawthorne. Much easier to wed the two and optimize short-term benefits-- there is a lot invested at Hawthorne.
Look closer; plenty of "no pedestrian" signs from street view.
