Tuxer··on Electric Vehicles’ Day Will Come, and It Might Come Suddenly
The first model Ss that have hit 10 years and 200k miles have shown an average of 3% battery capacity decrease.

Car batteries aren't phone batteries :)

Tuxer··on Norway's Plan for a Fleet of Electric Planes
Because he/she doesn't know what he's talking about. Jets will always cruise at their maximum allowed altitude except for some really short flights. In cruise the only thing you're fighting is aerodynamic drag (no ground friction) and climbing is the best way to reduce that.

If anything electric planes using their higher thrust will even climb quicker.

Tuxer··on California Moves to Require 100% Clean Electricity by 2045
oh I must have, I read this sentence "The state currently gets about 44 percent of its power from renewables and hydropower." as continuing with the current thought that hydro wasn't 100% clean.

Pump it up then.

Tuxer··on California Moves to Require 100% Clean Electricity by 2045
Once again, making me proud to pay CA taxes.

If they do not take large hydro into account when calculating this 100%, I wonder what we'll do with the dams. Destroy them to let the rivers free-flow again? Dams would have been a great store of energy for this project by pumping the water up during the day using solar/wind.

Tesla Energy must be salivating at all those batteries that will need to be constructed.

Tuxer··on Venezuela President Maduro 'survives drone attack'
GPS is passive only, you’re not emitting on the RF spectrum to get a fix
Tuxer··on Pilots who risk their lives flying tiny planes over the Atlantic
Depending on the plane, you might not be able to. Cirruses for example are composite planes whose structure AND wings from from a single piece of composite, therefore you can't remove the wings like you'd do on a Cessna, so you can't ship them on cargo ships (wouldn't fit on containers).
Tuxer··on Trump is going after California’s clean car mandate
The lack of regulations regarding car emissions imposes an unfair burden on California's air breathing residents, who must live on the same overheating planet as the other 49 states without any power in the voting booth to make them employ more planet-friendly transportation systems.

By keeping the exemption, the state is making things more fair for its residents :)

Tuxer··on Uber Neglected Simulation Testing on Self-Driving Cars, Insiders Say
As you become "good" at driving in harder conditions, you'll use your butt (which is really how you're physically connected to the vehicle) to figure out the traction state of the car, to know if the car is sliding, if it's close to losing the rear end or the front end, if it's pitching down or up, and so on. This is how you know which corrections to make to the vehicle to keep it going fast without losing control.

Pilots of small planes do the same thing. After a while you can just feel small accelerations and change of directions without needing to check some of the instruments.

Tuxer··on The SpaceDrive Project – First Results on EMDrive and Mach-Effect Thrusters
I have no understanding of physics, but given that 70% of the known mass isn't measurable, couldn't something like the EMDrive "just" (lol) send dark matter one way, and get momentum the other way?

This is probably stupid to anybody that knows about physics, but I had to ask :)

Tuxer··on Oculus Go
Gear does have a head model, you can tell really easily in pretty much every Gear/Go game by looking at parallax differences between near and far objects.
Tuxer··on Electric scooter “mayhem” sounds like when cars were introduced
I used one today for the first time, and loved them. Faster than an uber, 3$ instead of 10, environmentally responsible, and fun to ride. As long as we fine people for being assholes (riding on the sidewalks, parking in stupid places) I think they're a great step forward.
Tuxer··on Diesel cars can be banned from German cities, court rules
He/she meant in pure taxes
Tuxer··on Open Letter to the Airbnb Community About Building a 21st Century Company
Why does everything crypto related feel the need to create a whitepaper following scientific conventions, even when there is nothing scientific about it...
Tuxer··on SpaceX recovery boat spotted with huge claw-like “fairing grabber”
The soon to come on-board videos of this high speed boat trying to catch a fairing coming from space under steerable parachute will be AWESOME.
Tuxer··on Debut of SpaceX’s Falcon Heavy rocket now planned early next year
There is still a good chance they might do a FH Raptor-powered second stage :)
Tuxer··on Bitcoin hits $10,000
None of their wealth is solely controllable by a private key and 24 words.
Tuxer··on How Unreal Renders a Frame
That's not exactly actually (UE VR dev here). When you render a game at 90hz (or 60 or really anything), that means your total throughput needs to be 90hz, NOT that the frame needs to render in 11ms.

Since you're dealing with multithreaded CPUs + an asynchronous GPU, you can parallelize and sequentialize all this. How UE works in its DX11 and OpenGL renderers, on a 90hz game, is that you're gonna have the Game Thread (Physics/Gameplay) running for frame N, while the Render Thread (GPU commands / math ) runs for frame N-1, while the GPU executes frame N-2. This allows you a complete frame time of 33ms on a throughput of 90hz, at the cost of more latency.

Tuxer··on Delta Goes Big, Then Goes Home
A hurricane isn't a thunderstorm, and has very limited vertical movement in its airflows. The hurricane hunter P3s do it.
Tuxer··on Delta Goes Big, Then Goes Home
They did, this was a volunteer crew. Most of the passengers on the return flight weren't passengers in the normal sense of the word, but non-reqs, delta and other airline employees that were working in that airport and wanted to get out of dodge.
Tuxer··on Olin College Produces Founders at Five Times the Rate of Stanford
"it's not selection bias at all"

"I specifically went to Olin because I thought it would best help me become a successful entrepreneur"

Tuxer··on Boeing 787 In Flight Entertainment System Security fun
500k lb, at the very least :)
Tuxer··on SFO near miss might have triggered aviation disaster
There is, if you use it. In this case they were doing a visual approach , where you use eyesight in order to line up and land, because you have seen the runway. People do visual approaches in SFO as they are necessary to land 2 aircraft at the same time on the parallel runways ( they're like 30ft too close for parallel approaches on instrument ). It is still recommended to even in a visual approach, turn on the instrument approach systems ( for that exact reason ) but it looks like it is not mandatory for that airline.
Tuxer··on SFO near miss might have triggered aviation disaster
(pilot here) Yes, they are very well shown on maps, but it can be hard to map your diagram to what you're seeing, especially if it's raining or if it's at night, and even more if you're tired.

I never made the mistake, but can see how somebody in bad conditions would.

Tuxer··on Facebook: greater than 15% of employees are H1Bs
Sounds good :) Seaplane rating is a bitch to use unless you wanna buy one, I know of no club that lets you solo their seaplanes for insurance reasons. An old apple coworker used to own a Lake amphibian, looked awesome.
Tuxer··on Facebook: greater than 15% of employees are H1Bs
FB engineer for work, pilot (instrument/aerobatic rated) by hobby :)
Tuxer··on Facebook: greater than 15% of employees are H1Bs
FB currently has more than 300 openings. If you're qualified, please apply :)
Tuxer··on A plane so good it's still in production after 60 years
That's just because new material technology makes high wing aircraft not very useful anymore. Plenty of low-wings get certified by the FAA (the cirruses, diamonds...)
Tuxer··on Unreal Engine 4.15 Released
Right now it's extremely scene dependent. If your scene works well with it ( lots of far objects, not too many objects in the clip plane area ) it can get you 20+% perf wins. If you have a scene that doesn't work with it ( small rooms, lots of objects in the clip plane ), you're gonna lose performance, as there is a non trivial cost of running that third monoscopic view and doing the mono compositing into the stereo buffers.

The feature can be dynamically turned on or off though, so devs can work with that :)

We still have issues with transparency around the clip plane area.

Tuxer··on Free food and misery: the life of a techie
I work in tech in the silicon valley. That's just untrue.

There is a sense of alienation in being a small cog in a huge company shipping millions of devices, churning through code to get data from one point to another hoping that it'll make a difference to customers and that that feature isn't just another PR gizmo.

Tuxer··on US Court of Appeals Takes on Ridesharing in Aviation
Pilot here, I can assure you that a "puddle jumper" being flown by a certified commercial pilot is way more dangerous than a commercial flight. The certification necessary for an airliner is miles above (no pun intended) the certification for a GA (general aviation aircraft).

An airliner's resistance to weather, its ability to out-climb (it's pressurized) turbulence and ice, its ability to still fly with half of its engines destroyed, is something that doesn't exist in general aviation aircraft. An airliner can only be flown with 2 crew members, pilot and copilot, so that one being incapacitated doesn't end the flight right there. Such measures don't exist in general aviation.

Even airports are different. Big airports have control towers and radars to avoid midair collisions, excellent weather reports. The places I go to sometimes don't have either, I have to overfly the runway at 500 feet to look at the windsock and make an informed guess.
