They need to disclose a lot more of their methodology for this to be taken seriously. Regenerative braking that is used very heavily in electric cars cause a lot less brake pad use - not more. Teslas have normal tire wear for the type of tire they use. I don't have experience with other electric cars, but they are all small vehicles. It raises an important point I hadn't considered but certainly not to the detriment of electric cars.
>I assume payroll is tax-deductible. That the money you pay your employees can be deducted from the gross that the business earns before paying corporate taxes. What if we exclude foreign payroll and expenses from being deductible?
H1-B was created for the case when there really aren't enough qualified American workers. In some RARE cases there is a legitimate need to import IT staff. Making their salary not a business expense would be so costly that it would be more logical to get rid of H1-B altogether.
>If the employees are coming physically to the U.S., perhaps a minimum salary is in order as some suggest (based upon industry).
H1-B workers must be paid at least 60K. This is already a rule. Probably not enforced though...
>Maybe require the company to retain the employees that they're firing.
Companies should only be able to use H1-B when they demonstrate a qualified American worker is not available. The Department of Labor should be required to investigate complaints. This would preclude anybody from ever being fired.
I would support elimination of H1-B along with an expansion of green card limits for people who want to immigrate to fill jobs as fellow citizens.
Importing H1-B project managers who funnel IT work overseas for low quality/low cost development and support services is a horrendously bad idea. It's short term thinking that is damaging our companies and decimating the ranks of high skill service economy workers. If we get rid of manufacturing and service jobs, who will be supporting the 60% of the people who don't work in our country?
That's exactly what I was thinking. I was just theorizing that with something like the new kepler nvidia cards you might be able to process a pipeline of images as they were rapidly acquired to reduce gargantuan data storage requirements.
The far bigger challenge in my mind is the rf section of the system. It's inconceivable that a wearable mri could have a conventional MRI mechanism with a mechanical shutter. It would have to be a phased array with a synthetic aperture. That would enable a rapid scanning, but the big problem with that is the long wavelengths of the signal from the excited nuclei.
This is exactly my question. Its also an interesting one with implications beyond brain scans if this isn't BS. I do smell the distinct odor of BS here.
If it's for real, maybe they use a less powerful magnetic field and a much more sensitive receiver. Noise can be cancelled by stacking (as in astrophotography) many scans and processing with the new generation of graphics cards. Perhaps they are using scanning radio beams tuned to the resonant frequencies of specific elements to be scanned in place of the strong magnetic fields. Because of the relatively low frequencies and super long wavelengths involved, this is not easy.
Agreed. But by "we", I mean my fellow humans alive today.
My thinking is that by the time humans devise FTL travel, you and I will be long gone. I personally don't think FTL travel will ever be possible and if it does, it will be a really long time from now.
As for the others, in the unlikely event that aliens come here they would likely not be like us at all. For example, if its just me in a cage with a cobra snake I say I am alone.
There are some that think many of their fellow humans are crazy and dangerous and might just destroy the planet unless one of many of the possible and thankfully rare extinction events doesn't get us first. Watch a Trump circus or North Korean news reel if you think they are delusional. They are at least studying the feasibility of taking a few of our many eggs and putting them in another basket. Having water is the first key to survival. Knowing that human life on Mars can at least be possible should give you more hope for the long term future of mankind. This affects me in a meaningful way and it might have the same effect on you if you think about it.
...before they become overly concerned. With Moore's law sputtering, human like cognition is likely further away than had been hoped and hyped. While upcoming massively parallel systems from companies like Nvidia combined with deep learning will certainly usher in interesting applications, the complexity and energy efficiency of the human brain is a very tough act to follow.
tldr: We're not racist, we dislike the stupid corrupt H-1B system
Current H-1B Visa policy is decimating the corporate IT profession. There is an avalanche of large scale conversion from US IT workers to off-shore IT workers happening right now. Older IT workers (read age 40 and up) are not able to replace the jobs they are losing.
The majority of the H-1B visas are being issued to multinational (mainly from India) companies like Infosys, TCS, Wipro, HCL, and Cognizant. They can offer their services for a much lower hourly cost because these H-1B visa holders do not pay federal income tax, unemployment tax, minimum health care, and a variety of other costs mandated for American workers (ironically they do pay Medicare and Social Security). H-1B visa rules require these workers to have a minimum bachelors degree, but educational costs are far higher in the US than they are in India. Many of these workers simply meet the requirement with a degree from a diploma mill. Moreover, the majority of the on-shore IT staff are project managers who send the actual coding work to workers in foreign countries working for many cases for less than what most Americans think is a reasonable minimum wage. Americans simply cannot compete against this dramatically skewed playing field.
From a idealistic free market and free trade standpoint, this is good for America as a whole because consumers get their products at a lower cost. From a practical standpoint it is a disaster for the American worker who supports the federal government through the payment of taxes. The blue collar manufacturing profession has largely left the US and its economy has transitioned to a services based economy. With this new trend of sending services work overseas, the American worker is experiencing negative pressure on wages and suitable job availability.
The benefit to corporations is questionable. While an outsourcing strategy can certainly lower costs dramatically at first, it generally costs an organization much more in the long run. The loss of institutional knowledge causes firms to become inefficient and unable to rapidly adapt to a changing marketplace. Additionally, the outsourcing firms start with low teaser rate contracts and then increase cost on renewal. This is why most companies switch outsourcing firms every few years. This wreaks havoc on a companies ability to compete in the marketplace. There are also serious intellectual property and security implications to having foreign workers leaving the country with intimate knowledge of a companies internal operations.
All this migration to H-1B visa workers is based upon the lie that there is a shortage of STEM workers in the United States. There is no shortage of STEM workers in the US. There is a shortage of certain types of workers with ephemeral skills especially in hotbed tech localities at a wage that employers want to pay. They want low wage IT workers now. Because these companies advise lawmakers, policy is passed to benefit multinational corporations at the expense of American IT workers and the future of America's prosperity.
Another major lie is that an H-1B visa can only be granted if an equally qualified American is not available. The requirement is based upon an honor system that by law the Department of Labor cannot enforce.
This has absolutely nothing to do with racism against anybody including Indians. My niece is married to an Indian man and he's awesome - our whole family loves the guy and he's a fantastic asset to our country. I also like many of the Indians I work with and count many as my friends. There are Indian families that live where we live and they are great neighbors. I personally am a strong believer in immigration. The vast majority of Americans are either immigrants themselves or descended from immigrants within a handful of generations. To oppose immigration of quality people is blatant hypocrisy. The more skilled workers we have working in America, the greater the gross domestic product and tax revenue for
...or the universe is deterministic but the exact mathematical model would need to take into account the state of every massive and charged particle in the entire universe. Because of this concept, a statistical tool like QM is a useful approximation. Approximations like QM may not be the whole exact truth, but they are extremely useful. Approximations such as Newton's laws were used by mankind to send Voyager probes outside the solar system.
Although there are crackpot physicists who point to weird results from fictional mathematical stories, credible physicists understand that a cat cannot be both alive and dead until observed.
Just a couple more points:
>No time travelling photons, going backwards in time
Yep - no time travel. Time emerges from all particles' massive and electric influence on space which we say travels at the speed of light. Fictions like Dirac's equations implying that antimatter travels back in time are consequences of flawed equations that even Dirac knew did not accurately represent the true nature of reality.
>changing their wave/particle nature
Particles are waves. Credible physicists understand this. Photons are quantized because they are created by the motion of electrons whose orbitals have fixed dimensions dictated by the electric influence of the atom's nucleus. Einstein said as much when he explained the photoelectric effect by showing the quantum nature of the photon. Particle/Wave duality is a common semantic misunderstanding spread by people who have difficulty explaining and understanding this concept.
>All the theory built on this simple misunderstanding now a total joke.
I agree that there are a bunch of crazy ideas in physics (don't get me started on dark matter), but I can't agree that quantum mechanics is a total joke.
I've been wearing mine every day for 11 months and I like it. IMHO, if you don't wear one its hard to understand its utility. Other than aesthetics, resist the urge to criticize it if you don't have personal experience. Its one of the better "version 1" tech products I've tried. That said, it certainly not for everyone and there is a hell of a lot of room for improvement.
Pros:
It has encouraged me to be more active
It has had a dramatic impact on using reminders - I rarely forget to do things on time now
I never miss notifications for a wide variety of things and I have not had an audible phone ring since I started wearing the watch.
I routinely use Siri to set reminders and timers. Voice recognition is clearly the UI of choice for wearables.
I really like using Apple Pay with merchants that accept it
I'm crazy about the iGrill wireless temperature probe and the ability to see the food cooking status while I'm busy doing other things.
Having the GPS Nav reminders on my wrist has been unexpectedly handy
Cons:
It is fragile. If you drop it it breaks. I had to put an ugly case on it. The protruding rounded glass is a bad idea. No other conventional watch is made that way for a reason. You have to add the cost of Apple care into the watch because you'd be crazy not to have it
The responsiveness, especially for voice recognition has gotten worse with every software upgrade.
The heart rate monitor does not work very well. I have a normal wrist.
The battery life barely lasts a day especially if you are very active; you cannot wear it overnight to monitor your sleep because you have to charge it.
Observations:
The Apple watch is screaming for upgraded hardware.
I wish Apple concentrated on the "movement" part of the watch and let third parties make boatloads of user installable cases and bands
It needs a small white light to use as a handy always available flashlight
It takes too long to charge. If it could fully charge in 30 minutes, I could wear it overnight and charge it while getting dressed.
It needs a way for developers to add data that can be shown with a glance on the standard watch faces. I hate having to fiddle with the watch to get basic data from an app. E.g. I wish the grill temperature could be shown with a glance instead of navigating to the app on the watch.
It needs to select apps to be actively shown based upon what I'm doing. E.g. if it sees my heart rate is up, show the workout tracker by default.
I'd like to configure different haptic feedback notifications for events
I'd like to associate certain wrist motions to trigger programs; e.g. a double wrist rotation to turn on/off the flashlight.
Its too iPhone centric. There should be an industry standard wearable API
I think we may be agreeing violently. I'm trying to express my opinion about patents that stake a claim on territory yet to exist. Practical real world examples of this invention are as plausible as fusion power generation - certainly possible but certainly many years away. Having a large company prematurely claim ownership of the idea stifles innovation. Additionally, this patent is filed in South Korea. There is also prior art. Its also an obvious idea to a practitioner in the arts.
Patents should not be issued for inventions without working models. With the principle of first to file, anybody can file a patent for anything. This stifles innovation. Why would anyone work on a genuine effort for an innovation when a troll has decided to squat on an idea they have no intention of developing.
I agree that faster charges may be impractical without wireless. We have a 100 amp 240 vac circuit In our garage and the Tesla charges (approximately) at 80 amps and that amount to 60 miles of range for every hour of charge.
As a commuter car this is fine and that is really all we use the car for. For long range trips, we have a small hybrid SUV and frankly we could just as easily rent a car for those rare occasions.
For long range driving trips in an electric vehicle, I see no practical charging technology in the near term that approaches the speed of gasoline. Even a 30 minute charge is too long. Automated battery replacement seems to be the only real solution today. Tesla demonstrated this several years ago with the Model S.
"Have you ever heard something spark when you plug something into the wall, or unplug it?..."
When the charging cycle begins on a Tesla and the initial contact is made, there is essentially no voltage present. The car slowly increases the charging current and continuously monitors the input voltage. If there is an excessive increase in voltage drop as charging current is ramped up, the charging cycle is aborted. This helps prevent fires due to bad connections in any part of the circuit.
Often I want something and when I get it, I realize I didn't really want it after all. I think wireless charging falls into that category.
The reality is that electric vehicle owners equip the place they park their car overnight with a high capacity electrical circuit. It takes less than 30 seconds to plug in the car after you park.
Doubtless a wireless charging solution could be made safe and effective, but it would cost more. We don't need to find ways to make electric vehicles more costly.

A law that cannot be enforced by the Department of Labor. Unenforced laws are the basis of corruption. H1-B law needs fixing.
What would a union do? Pay off our politicians with campaign donations? We need less corruption - not more.

Given the vast distances and time that separates anything we would identify as "us" we already know that we are for all practical purposes alone.
You might be right, but I think people who will trash the planet will find may ways to rationalize their actions.
