The Boeing 747 has its instantly recognised "hump" precisely because Boeing thought at the time of its design that it wouldn't have a long sales life as a passenger aircraft, as the future was "obviously" supersonic for passenger transport. Therefore, the design was optimised for roll-on roll-off cargo transport through the nose section, which made it a very good cargo aircraft and thus increased its forecasted sales life.
I understand the area rule had something to do with it too.
Why is AT&T showing me ads when I use AT&T's web mail when I pay then $50 a month?
Or is why Amazon, NewEgg, etc. showing me ads when I'm about to pay them money. I see ads for their competitors while shopping on their website. Have they forgotten they are the one place on the internet where people are willing to pay for their services?
Google has been slowly changing from a dotcom tech company to a multinational conglomerate for a few years now. This is just them acknowledging that fact and structuring the company accordingly. This is similar to how United Aircraft became United Technologies in the 70s.
By the time you do the monthly payment plan via Verizon you're going to end up paying what you likely pay for the 2 year contract. I doubt there is going to be a substantial cost difference. Verizon already had/has plans of this nature.
I also notice they don't charge interest on those monthly payment plans. There's still some subsidizing going on...
Verizon has been walking away from the subsidized phone model. You've been able to ask for a non-subsidized rate for a while now. The prices are even listed on their website. However, there is still a catch! The monthly installments for a new phone are at 0% interest. That means they are using your monthly service fees to pay the interest on the loan. Paying for the phone in full would be turning down a discount in terms of finance charges. I wonder if this will change when the new plan comes into effect.
Maybe this will make buying a Nexus phone finally make sense. Too bad the "Google Play Edition" program is dead. This could be good news for open source phone projects, and Firefox OS.
You do understand that ocean currents are not straight lines, right? For chrissake it's taken years for the Tohoku tsunami's wreckage to make it the Pacific Northwest.
My favorite example is the shipping container full of rubber ducks that an oceanographer tracked for 15 years! We may be finding pieces for decades.
It's just like banning people from joining them. We should be lining those people up and flying them over there right after they sign papers saying they aren't citizens anymore. Let them go, fight and die as long as they never return.
Banning them from joining does effectively the same thing. It's not like someone is standing there physically preventing people from joining. If people go and join, they get put on a list. If they try to reenter their home country they are arrested and rot in jail.
Remember, making something illegal doesn't prevent it from occurring. It just provides a means to prosecute those that commit that act.
I've been saying for a few years that if you just had a few solar panels in your back yard, and didn't want to go through the expense of all the inverter stuff, you could just use it to charge a small battery and power a DC air conditioner.
The big advantage of the DC air conditioner is that you can run it in parallel to a traditional air conditioner and don't have to worry about the grid connection. This will take load off of the main air conditioner and save money. No special controllers needed, just set the target temperature on the DC unit below the target of the traditional system. That way the traditional system should only run when it's both hot and dark/cloudy.
It's been a while since I took electronics. Doesn't power consumption increase with lower resistance for a given voltage? These claims seem counter intuitive.
As an automotive engineer, I'm frightened by the rapid response to this issue. This isn't Facebook. When an auto manufacturer "moves fast and breaks things" people get hurt. Every change should go through months of validation before being released to the customer.
I realize this exploit is a concern. However, is Chrysler sure they haven't introduced a bug with far worse consequences by implementing this change?
I too am an engineer, and I optimize things for a living. However, you have to exercise some level of restraint. There are plenty of projects that can be marginally better, but the customer won't notice or care. At some point a project is "good enough" and you ship it. If you obsess over making everything perfect you will either end up making vaporware or annoying your customers with seemingly pointless changes (e.g. Google Maps).
This has taken me years to realize. As an engineer I want to optimize everything. However, optimization for optimization's sake is a waste. Focus on what will really improve the experience for the end user. If the end user thinks it's perfect, LEAVE IT ALONE!
Grandpa was an engineer too. Learn from his years of experience.
Google Maps is the worst. Just when I figure out the interface they change it on me. One time it took me a week to figure out how to make it avoid tolls.
As Grandpa always said, "If it ain't broke, DON'T FIX IT!"
Most of those outsourced parts are electronic, because Elon Musk doesn't own a semiconductor factory (yet).
I doubt he owns his own bauxite mine or aluminum refinery either. The rabbit hole goes much deeper than just shaping raw materials. The quality of the material was the root cause in this case.
...it might pass the test but you still don't want to reuse it. There has to be some cutoff point where you're causing long term damage, but it's still functioning to requirements, right?
Random testing can only pick up systemic faults within an entire product line not random ones.
Statistics is your friend in this case. Random testing should show a large standard deviation (assuming they test to failure). You should then be able to calculate the probability of failure.
This may not be so random....Or some shlub forgot to heat treat two of the struts.
But... Ford's system IS Toyota based... they licensed the HSD system from Toyota.
The details are what's important. Did they license the technology, or buy it from Toyota Who was responsible for the software, calibration, and integration?
Wikipedia says Ford licensed the technology but developed it themselves.
They’re great. I’ve never seen a cell go bad or a module. I’ve had to crack a few open (only twice) and put new cooling fans but other than that they are perfect. The camry and prius burn battery packs like crazy.
5. In order to have a chance to regulate the temperature well - and not keep cycling through blasts of heat and cooling - they'll need multiple temp probes, and an awareness of the outside temp and humidity as well, since ceramic insulation or no, the external environment will play a huge factor.
If your PID controller is cycling like that something is seriously wrong. Even a poorly tuned controller should eventually stabilize, unless the gains are way out from where they should be. The controller should be easily capable of overcoming fluctuations in ambient temperature, even in New England.

Hydro? Are you insane? In 1975, an 18GB hydro-electric dam system in China failed, killing at least 170,000 people. And 11 million made homeless.
There are no safe energy sources. It's not about where the energy comes from. Energy itself is dangerous.
Ever see a wind turbine failure?

Magic Online, the digital version of the famous trading card game, is currently undergoing a kind of "economic recession".
I find this ironic as NPR recently praised the MTG team for their economic skills.
Are we just supposed to believe Microsoft when they say "Trust us, this is secure"?
Yes, it's secure because they will give all of your data to the NSA for safekeeping.

I imagine jet wings that are empty of fuel will float around for a while.
Wings that are full of fuel will float too, because jet fuel has a lower density than water.

It's called the yield strength. It's very much measurable.

This may not be so random.
You can test random struts, but you can't test ALL struts or you're left with no struts. Sounds like they didn't test the right ones is all.
Who says you have to test them to failure? Just test them for the designed load.
