I've never really had any idea what I'm doing and I haven't failed yet. I don't even recall reading about bricked devices while involved, just the warnings. Warnings that apparently make many very fearful. I don't know how these concerns are any different than the myriad of ways you could destroy a self built PC, modding an x box, recompiling a linux kernel, etc. Suddenly, straight forward steps on xda and everyone is afraid of bricking a device. An easy way (and smart for other reasons) to mitigate that risk is to simply use older hardware. Due to the absurd frequency of turnover in the mobile space, old hardware is effectively free and disturbingly capable.
My first two phones were t mobile windows mobile 5.1 thing and a motorola cliq2. They were not hugely successful models, but they both had smallish dev communities doing the job. My recent phone, sprint my touch 4g, is essentially a galaxy s2, but with some differences that require its own treatment, thus the community is also small. Nonetheless, there have been many, many options for all these devices. (Not to mention the nexus and galaxy devices I've worked on)
In summary, I think you're overstating the challenges. Just do it.
I don't think you should assume about what not is. There are already lots of incremental autonomous driving controls. And they work fine. And they do not change the relationship between a driver and his liabilities.
facebook probably can't generate sufficient profits off an activity like this. since their IPO they have essentially been squandering equity in all directions, including this one, to chase potential revenue. their growth targets are probably impossible (by a factor of 10 or more) without a massive change in revenue model. And so they chase whats app, flying drones, and spy tech. Its an impossible, hilarious, and economically inefficient circus, that is now playing out for the second time in 20 years, with mostly the same people involved. And these are the prized achievements of a system for which most here even express ideological preference.
I would also think "slashdot people" are capable of not allowing perfect to be the enemy of good. But no, apparently incremental improvement in autonomous driving controls are unacceptable. Nothing less than Kit picking you up at the bar and driving to NY from Boston during Snowmageddon will suffice.
Alas, I guess we're both wrong. We'll you're wrong. I'm actually just sarcastic.
Why aren't all you nerds rooting devices and using whatever OS/kernel/apps/bloatware/radio/store you want? So many people here complain endlessly about carriers and poor support. Yet you can basically get whatever hardware you want with whatever OS you want. Pair VOIP and ubiquitous wifi with sleazy or hyper discount data service and the effective cost of mobile computing is 1/10th that, or less, compared to the major carriers. Yeah. I get it. It sucks that it has to be this way, but that is only the case for people who can't work around it.
Cheap, reliable, and sustainable telecommunications networks & services exist under virtually all regulatory environments imaginable from one end of the spectrum to the other. We can make any of them work as long as we aren't beholden to the few entities that stand in the way, which is essentially the current arrangement the pervades the US industry.
Apparently the opportunity to turn any and all workable solutions into an ideological shit show is more important than functioning government and quality services.
I don't think gas boilers particularly benefit from small size.
Smaller units cost less. Units with properly utilized burners are more reliable, burn cleaner, and save energy. 1 added year of life and 0.6% net thermal efficiency don't matter per unit, but add up over installations.
why can't I use cheap gas heated water?
I don't know why you have that limitation. However, small hot water draws have disproportionately high % of energy loss. Resistance heating a 1L load may not be that costly compared to losing 80% of your gas-heated water to warm up room temperature pipes.
However, at this point it's less "internet of things" and more "internet of select heavy appliances"
Yes. Compressors, Fans, Pumps. Maybe lights, maybe temperature dead bands.
But an awful lot of the IoT hype is amazingly faddish and appears to me to be utterly pointless.
I would be surprised if we have already recognized the main benefits of cheap connected things. Although I agree that it is unlikely to be the type of hokey consumer garbage that dominates headlines.
Tough life you have. It's a shame you can't let your horse shit all over the street either. Incandescents have no redeeming qualities outside of heating, for which they remain available. A large electric kettle will last for 50 years, and high power vacuum cleaners aren't more effective than lower power properly engineered models.
Likewise with the internet connected dishwasher and washing machine. I have to stand right next to them to fill them up and put detergent in. I really don't know what use having them internet connected would be
You put them on fast DR mode because you actually don't care when they run, the utility neatly staggers run times within your acceptable parameter windows for 10,000 customers with the net result a better managed and less expensive grid. Your wife complains about noise so they run when she leaves the house. We eventually saturate the grid with renewable energy and with your agreement, the utility will let you run them for free to soak up peak solar/wind output. Your hot water heater is connected to your end use devices, your hot water loads communicate so lower priority (dish/clothes) services will not interfere with your main hot water needs. Now you can downsize equipment. You will save money. Your rightly sized equipment will operate in narrower (design) boundary. It will be efficient. You will save money. Now lets do this with all our compressors, motors, and fans. We can now work together. Save energy. Save money without really doing anything but coordinating with each other on a level that is basically invisible to the end user. And if you don't want to participate? Sophisticated pricing mechanisms will allow for that. You can pay more to fund your all your personal priorities. It works for everyone.
I really find it strange that some eschew and then actively campaign against advanced voluntary technology simply because they can't imagine how they will use it. Think of the things we would have abandoned in the past had we listened to people that thought this way about technology, would there be any progress ever? I also think these arguments of big data are very over played. The space is very big, trendy, and it will be very crowded. There are low enough barriers to entry that even paranoid privacy fanatics will get their doodads too. This amounts to a crowd of old people complaining about trampling the grass.
Expensive? you can get any radio technology and an ARM chip for $5. Nest is sub $20 hardware. You wouldn't ever notice the incremental cost of they put it into any appliance or device costing $50 or more.
That pretty much sums up third of the skepticism on slashdot. Another third comes fantasizing imaginary scenarios. And the last third is because each slashdotters experience and education render them the smartest person in the world, able to speak authoritatively on any topic of their choosing,
"The biggest problem the current generation has, is they have accepted the idea they can't when all the ones that have come before knew they could."
Do you have any evidence to support this claim? I find no lack of American delirium in Gen X or Gen Y, in that they'll all work hard and die rich. Perhaps an extra bit of wisdom/cynicism about that which they cannot control, but no lack of the perverted thinking that yields disproportionately productive workers relative to the rest of the world.
Sounds like a case of the yesterdays to me, uphill both ways I hear, but ye overcame.
This is a great off topic addition to the thread. One I try to add as frequently as possible. That often cited statistic is from a brief period many years ago. China's coal construction has seriously tapered off in the last several years... in favor of wind and solar. China's coal consumption and bogus factoids surrounding it are often used to justify all sorts of ignorant nonsense regarding GHG, grid modernization, economic competition etc.
The real story is that China, not the US has driven down the cost of solar to 1.11 $/kWh installed. Cheaper than all other forms of energy on earth, including imported coal. The only remaining barriers have nothing to do with the technical or economic costs of solar energy. Its all about waiting for the institutional inertia to catch up with the pace of change.
What a bizarrely worded statement. If Holder's actions reduce seizures by 43% (the maximum likely given state accounts for 57%) you won't be happy to give him due credit for it?
Go get a high GRE score write stellar essay and pick a program. Well rounded highschool students make great college students and well rounded college students make great scientists. Non stem BS degrees are typically less comfortable with fundamentals, which is more work and makes for a harder time around orals, but they get there. Remember half the american students with stem undergrads wont know fundamentals anyway, since that knowledge isn't part of the application process Another fourth are swapping fields so their fundamentals are less transferable. High caliber, well prepared students (hot on fundamentals) are rare. I am not one, but I did catch up from woefully deficient fundamentals.
plan b
Pick a prof you want to do research with, follow their advice and their advocacy will make it a cinch.
part2 to plan a and b, dont listen to any naysayers unless they supply advice to overcome the small surmountable problems you may encounter.
my typing and thinking are somewhat compromised atm so please overlook errors
I'm always puzzled that people who present critical views of renewable energy always seem to rely on old data. News flash, massively popular and fast growing industry changes quickly. You can build utility solar plants that profitably sell electricity at 0.06 $/kWh. Look no further than report released by Lazard today... When prices are 30% lower in 5 years, like will happen, they'll be citing 0.06 $/kWh as too expensive, meanwhile ppas will be signed for 0.045 $/kWh.
this is such myopic thinking. you do know there are hundreds of thousands of educated people all over the world with agreeable AND disagreeable view points that are not contaminated by your petty perspective, right?
No. the 12% is not the cell or module efficiency. It is a low ball average on a modern, total AC system efficiency.
One just has to look at your final result to see that something isn't right. I don't want to pick apart your methodology, but frankly it is weird, and produces a result that is in conflict with power measurements from actual systems. See the other follow up to my own. Redo your calculation using a different method.
the german data I cited is the annual incident radiation on a horizontal plane per m2. Find a figure you like and match its location in online calculator, PVWatts for example is generally conservative. You will find you are off by an extra 1 / (0.12-0.15) because of your double counting somewhere.
Retail customers only need to displace retail costs. Avoiding net metering, the best thing to do is self-consume your solar energy and avoid the retail rate you would be otherwise charged.
Sure the answer is to design for winter load and use summer excess to charge something seasonal, hydrolyze water, make syn gas, heat the earth around your house, etc.
