Engineers are leaving Amazon in droves due to how poorly they're being treated here in Silicon Valley. If they shut down a department they lay off everybody in that department even if they're quite talented and would be useful in another department. The politics are also growing quite bad. I say this knowing someone who was one of the first employees at Lab 126. They're making stupid decisions from high up (i.e. Jeff Bezos) like the doomed from the start fire phone. Despite flying back and forth to China frequently they made this person fly coach, despite being one of the most senior members there. He can't wait to say goodbye as soon as his stock finishes vesting. I have another friend who ran their software build system who was constantly called at odd hours of the night who had to deal with constant shit from the data centers refusing to do what needed to be done besides running his life ragged. He quit once his stock vested to join a startup, which is far more relaxing for him. A lot of senior people are fed up and quitting due to the working conditions and poor management.
Jeff Bezos thinks he's Steve Jobs but he lacks Jobs sense of style.
I'm disgusted with how Amazon treats their employees, and I say this as a stockholder who has done quite well off of their stock.
As far as I'm concerned, all employees should be treated with dignity and respect, from the janitor on up. Their treatment of warehouse workers is sickening.
It doesn't help that Mt. Rainier is also rotten, full of hollow caves and eaten away by sulfuric acid. The most dangerous part is that it is quite unstable and will create a cataclysmic flash flood of mud, rock and ice, known as a lahar. About 150,000 people live on top of old lahar deposits.
Unfortunately this is not the case. As the ocean acidifies it becomes harder and harder for coral and shellfish and many plankton to grow. This affects everything in the ocean. It's not just the ocean temperature that's changing.
That was one reason I chose to use Kaspersky. Once my license expires... never again. With all the crap coming out of Russia I don't think I'd go with them again anyway. Almost all of the spam RBL hits on my mail server are from Russia, the rest are from China. I wish I could just firewall off both countries.
There are actually many uses of this waste heat. For example, it could be pumped around a town to provide hot water or heat in the winter, or it can be used by industrial processes which otherwise would use conventional means to generate heat. Besides, all existing power plants produce a lot of direct heating (with the exceptions being solar and wind).
It has been found that there are taste buds for sweetness in the stomach, intestine and pancreas as well, so it's possible that these may have some effect.
Even when I forget I usually still have plenty of range since my commute is around 45 miles per day. It's not like a Leaf or the other low-range EVs. It certainly does look cool. I use their wall charger, which also looks cool. It's quite small compared to most of the EV chargers I've seen, especially considering it handles far more current than most of them (80A). The funny thing is that the local code requires a shut-off within 3-feet and the shut-off box is about 3 times as big as the charger! So far I haven't found a smaller 100A shut-off.
Exactly. I've run port scans against my Model S and there are no open ports. All communication is over OpenVPN making remote hacking much more difficult. As has been stated elsewhere, the researchers first needed physical access to the internal Ethernet network of the car.
Which is why the hackers first had to get physical access to the car in order to hack it. They were not able to hack it remotely until they first gained physical access to the internal Ethernet network.
When I worked at Atheros we used Faraday cages to house the wifi cards and used direct coax hookups. Even with that I could still pick up a dozen or so weak wifi access points. The Faraday cages were quite nice, 1/4" polished stainless steel.
It doesn't really matter. For an extra $100 they will come to you, unless it's a warranty issue in which they wave the charge and send a tech to your location.
Actually OTA updates do affect low-level issues. I have had updates that affect things like windshield wiper operation, acceleration, the door handles and more. It's interesting when the car is installing an update. You hear all sorts of clicks and noises as various subsystems are updated and reset. I don't know if they can update the cellular modem or not, but I would not be surprised if they could.
If worse comes to worse they can always send a technician (called rangers by Tesla) to your location and do a manual update.
I have a Tesla model S. It takes me under 5 seconds to plug it in and 5 seconds to unplug. I just push a button on the end of the cord and the rear reflector opens and I just plug it in. The connector itself is extremely well designed, one of the easiest connectors to plug in due to the funnel-like design so you don't have to line it up exactly before shoving it in and it locks in place. To unplug, just push a button on the plug and pull.
People keep saying it takes too long to charge. Bullcrap. It charges while I sleep and I spend a lot less time plugging and unplugging the car than I did filling my gas car.
The only use I see for this is marketing and for people who have more money than sense, although it might prove to be quite popular in Japan. This could be somewhat useful for superchargers that are not covered with solar panels since you won't have to leave the car at all, although in my case I usually get out and grab something to eat with the money not spent on gas to return to a fully charged car. Every time I stop the car is usually ready to go before I am.
I agree. I've had nothing but trouble with Intel's graphics drivers compared to nVidia. Generally the nVidia proprietary drivers just work and work well.
I have never found Intel graphics hardware to be the most stable for Linux, far from it. For years I had a lot of problems with Intel graphics such as every time my laptop went into standby the graphics would never recover. At work I had two identical desktops and with the same image I could only get X11 to work on one of them and then it refused to support the monitor's resolution. The other identical machine would just lock up. I dropped in nVidia cards and suddenly everything worked well. It just worked and ran at the monitor's native resolution. I've also had awful experience with AMD/ATI's drivers. By far the best experience I've had has been with nVidia's proprietary drivers though there have been some versions that were buggy they generally have been great.
The AC is actually hooked up to the main inverter since the AC uses an AC motor. DC motors require brushes and are typically less efficient than AC motors. There's no such thing as a purely DC motor. A "DC" motor typically uses brushes to generate AC for the coils.
HVAC uses 3-phase AC power which is actually pretty efficient for motors, especially if you want motors that are going to last a long time. Pretty much all brushless motors are driven by AC (even computer fans have a controller inside to generate AC). 3-phase is great for motors that run at a single RPM, such as what is used in compressors and pumps for HVAC.
I'm working with brand new prototype boards and all of the embedded boards I work on have RS232. The reason for this is that it's dirt simple to implement and only needs 3 wires. I only need a few lines of assembly code to initialize it and send or receive a character. It also doesn't care about things like DHCP servers and whatnot, only that you get the pinout and baudrate right. On multiple occasions it was the only way to transfer new images to a board to fix the flash. Of course on some of these boards we use a USB to serial chip on the board and I can crank the baudrate reliably to 10Mbps.
I've also had occasion where I needed to use RS232 to get into my router due to screwing up the network interfaces.
I have a friend who helped design the Tesla drive train. He said they do so much in house since they have a lot of problems with components from 3rd parties, especially China. Look at all the transmission failures the Roadster had until they did their own in-house design.
It also allows for them to make changes quickly. Apparently they make tweaks to the design of the car almost every week which would be impossible to do with a heavy reliance on 3rd parties for manufacturing.
I've accelerated hard in my P85 from a red light in front of cops before (realizing it after the fact) and never had an issue. I know to let up on the accelerator by the other side of the intersection since I'm already at the speed limit.
The nice thing about the Tesla is you don't have to do anything special to get insane acceleration without just spinning the wheels and smoking the tires. Just mash down on the accelerator and let the traction control do the rest. I have a P85 and it's a lot of fun.
My experience with my Tesla P85 is that the traction control is extremely good. It gives just a little bit of slip. There is virtually no difference in 0-60 time with it disabled vs enabled.

According to TFA it should be energy-positive, producing at least 3x the energy it consumes with room to expand that to around 5x.

I do it every time I have to stop at the metering lights when traffic is moving nicely on the freeway in my P85.
The downdraft is important if you're doing 1.1G acceleration which is what the car is doing.
I've accelerated hard in my P85 from a red light in front of cops before (realizing it after the fact) and never had an issue. I know to let up on the accelerator by the other side of the intersection since I'm already at the speed limit.
The nice thing about the Tesla is you don't have to do anything special to get insane acceleration without just spinning the wheels and smoking the tires. Just mash down on the accelerator and let the traction control do the rest. I have a P85 and it's a lot of fun.
