thebluehawk··on Model 3 achieves the lowest probability of injury of any car tested by NHTS
True, and that never happens with cars with gasoline in the tanks.

thebluehawk··on Tesla Q3 2018 Vehicle Safety Report
Also demographics. All Tesla cars (at least the ones with autopilot) are less than 5 years old, and typically driven by a subset of the national demographic due to their price. But they are comparing crash rates of ALL cars, including 30 year old clunkers with few safety features.

I wonder how the numbers would differ if they were to, for example, only compare to cars of similar years, or filter so the comparison is of the same demographic, or at the very minimum compared to cars of the same class/price.

With all that said, I love what Tesla is doing to advance safety features and technology. But these kinds of numbers leave a bad taste in my mouth.

thebluehawk··on Kubernetes Is a Surprisingly Affordable Platform for Personal Projects
Docker (at least on my mac) now comes with kubernetes built in, so you can just click a button and instantly have a kubernetes cluster running.

As for an app deployment tool I've had good success with Helm. It allows you to define all the services, app, variables, etc. that your app needs. Though the templates do seem to be a bit convoluted and hard to read at times if you aren't careful.

thebluehawk··on Organic solar cells set 'remarkable' energy record
I think you mean "piqued".
thebluehawk··on Shortage of charging stations to become a bottleneck to mass adoption of EVs?
I road trip regularly with my Tesla Model S. You would be surprised at where there are charging solutions. Any RV park can charge you up over night. If you use superchargers, it's hardly slower than a gas car. A 600 mile day that would take roughly 9 hours of driving and 1.5 hours of stopping (getting gas, eating, bathroom breaks) in a gas car takes about 9 hours of driving and 2 hours of stopping (charging, eating, bathroom breaks).

To me that's totally worth the savings on fuel and the fact that the car does 90% of the driving for me. If you left at the same time, you'd beat me by 30 minutes, but I wouldn't feel like I'd been driving all day, and I would save $50+ on gas.

thebluehawk··on Musk mulls taking Tesla private, Saudi sovereign fund builds $2B stake
You do have to keep in mind the further losses in converting it back to low voltage AC using very large and expensive inverters / transformers.
thebluehawk··on SpaceX set to re-fly a Block 5 rocket for the first time tonight
It's important to note that the first stage (which is about 70% of the rocket) is the part that is being reused. The top of the rocket (the second stage, the fairings, and the payload) are not reused (At least not yet. They are working on recovering fairings and there are rumors of second stage reuse).

When the stages separate, the first stage is going about 1.5 - 2.5 km/s. Then the second stage takes the payload the rest of the way to orbital speeds of 7+ km/s, and the first stage returns to earth.

So the first stage is going fast (several thousand miles per hour) but not as fast as things that re-enter from orbit. It still does need heat shielding, but not as much as the space shuttle or a capsule.

thebluehawk··on GitHub Commit Forgery
Most git servers have an option to only allow commits to go through if the ssh key that is pushing the commit matches the SSH key associated with the account of the "Author" field. Easier to implement than enforcing PGP signing.
thebluehawk··on Show HN: A map that shows you how far you can go for a given time or distance
Type in one address, click compute. Type in another address, click compute. It overlays them on the same map.
thebluehawk··on It’s called vomit fraud. And it could make your Uber trip really expensive
The problem is that Uber doesn't care. I've had a driver say they picked me up, and I can see them driving away on the app while I'm standing on the sidewalk. I cancelled the trip and Uber still charged me for a partial trip even though my phone was reporting I wasn't in the car.
thebluehawk··on Blue Origin successfully lands both booster and crew capsule after test launch
Which to be fair, Bezos will die long before he runs out of money, even pouring several billion a year into Blue Origin.
thebluehawk··on Blue Origin successfully lands both booster and crew capsule after test launch
> Enjoy the view etc, and then the second stage relights to cancel your velocity to 0

That is not feasible. Your second stage would have to be roughly as large as an entire orbital rocket in order to slow itself down from orbital speeds to zero, which means your first stage would have to be massive in order to push the second stage into orbit.

The reason every vehicle that re-enters the atmosphere uses a heat shield is because it's way easier to carry a relatively light heat shield that sheds off the speed than to carry the massive amount of fuel to shed off the same speed.

Literally the first thing I did was remove the Siri button from the touch bar.
thebluehawk··on Nissan Admits Internal Emissions-Test Results were Falsified
True, no ethical engineer would write "DestroyBaghdad", but how about perfectly reasonable "set custom threshold for test" function that lets the client pick? And then the client chooses an unethical value.
thebluehawk··on Massive Comcast Outage Hits the US
> customers urged NOT TO CALL 911

Do people really do this? I can't even comprehend this.

thebluehawk··on Keyboard Service Program for MacBook and MacBook Pro
No, the screen is the screen. The lower part of the laptop (where everything but the screen lives) has a case made of two pieces of aluminum. The topcase, which is the top half of the aluminum body, and has the keyboard mounted very deep into it as well as the logic board and other parts. There is a smaller piece of aluminum that screws to the topcase to hold everything inside.
thebluehawk··on States Can Require Internet Tax Collection, Supreme Court Rules
And if the retailer really doesn't like it, they can just not sell to customers in the state. But we know that's not going to happen. Like you said, the customer is the one paying the taxes, and the customer is the one who votes to elect those who make the tax laws that affect him.
thebluehawk··on Tesla sues ex-employee for hacking, theft, and leaking to the press
Um, you realize that the battery modules for the Model 3 are produced in the Gigafactory. So problems there would definitely impact vehicle production.

Also, time that Elon and other employees spend on this guy take time away from more important things.

thebluehawk··on Tesla won’t give drivers their own crash data without a court order
I mean, that seems like a pretty open and shut case for insurance... What is the purpose of needing the additional data from Tesla?
thebluehawk··on Gnome has moved to GitLab
They moved from bugzilla to GitLab (not GitHub)
thebluehawk··on IBM Watson Health slashes workforce
The ones that aren't hand-coded tend to act poorly, or racist, or worst.
thebluehawk··on Ditch the Batteries: Off-Grid Compressed Air Energy Storage
SCUBA tanks have a "burst-disk" or a weaker part of the tank that is designed to fail first, rather than the whole thing exploding and launching shrapnel. It's still violent and can throw some shrapnel, but it's much less. Also when SCUBA shops fill tanks they usually put them into a container that would somewhat contain that.

I imagine something similar could be done. It's not like there are zero safety mechanisms with compressed air.

thebluehawk··on Tesla's Autopilot Chief Keller Steps Down After Two Years
> I think it is cognitively harder to use autopilot and pay attention, than to simply drive safely.

Just out of curiosity, have you driven long stretches using Autopilot? I just did a road trip and on Tuesday during which I drove 11 hours, most of which using Autopilot. I emphatically disagree with you. I'm able to stay more aware of traffic and situations around me because I'm not having to constantly do the tedious tasks like staying in my lane and monitoring my speed (they aren't hard tasks, but take some amount of effort, and are mentally fatiguing after several hours).

thebluehawk··on Selling full autonomy before it's ready could backfire for Tesla
I don't disagree with your points, other than my definition of "constantly" must be different than yours.
thebluehawk··on Tesla Was Kicked Off Fatal Crash Probe by NTSB
Same. My other annoyance about every single one of these threads are people making comments about how unsafe it is when you can tell they've never even driven a car equipped with it.
thebluehawk··on Tesla issues strongest statement yet blaming driver for deadly crash
Autopilot is not an implementation of self-driving cars... You have a completely wrong understanding of this system.

It's basically cruise control that has some lane keeping abilities. If you put your (non-TACC) car in cruise control on the freeway and then ignored everything around you, you will rear end someone, and it's not cruise controls fault. If you put a lane-keeping assist car (like Tesla or others) and completely ignored the road, it will crash eventually. AutoPilot is cruise control with some lane keeping abilities, it is not self-driving. You choose when to activate it (just like cruise control), and every single time you do it tells you to pay attention and keep your hands on the wheel.

thebluehawk··on Tesla issues strongest statement yet blaming driver for deadly crash
That's because he is wrong. The radar is active at all speeds. In my experience, the radar basically only identifies cars and car shaped objects.
thebluehawk··on The Battle for Best Semi-Autonomous System: Tesla Autopilot vs. GM SuperCruise
I'm really confused. When describing the "Operational Domain" The author explains that a Tesla he drove 18 years ago handled a sample drive on FDR with two disengagements, while the Cadillac wouldn't stay engaged when he tried the same drive. Then says the Cadillac wins by a hair. How does a brand new system that doesn't work reliably win over a system that's been working better for over 18 months?

Ariane 5 had an anomaly just two weeks ago where they put the satellites in the wrong orbit.

thebluehawk··on Power Prices Go Negative in Germany
You are misunderstanding the wholesale price that the utility companies pays with the price they ultimately charge the consumer. For the consumers, the electricity was not free nor negative. They were charged their regular rate.

But yes, negative prices incentivize large scale batteries or other ways to make the supply and demand match up better.
