>You don't pay at Tesla stations

Tesla is a money losing company and its cars and its own funding are subsidized by the US taxpayer. $108m in losses last quarter.

Yeah, its neat they can pull this trick, but its meaningless as its clearly non-sustainable. Show me profitability, especially when they're off corporate welfare from my tax dollars. Why are the working poor and middle class families being taxed to make luxury $100,000 cars cheaper for the top 10%?

I'm getting a little sick of paying for a rich person's tax break on a $100,000 car. The reality, regardless of hysterical fanboy HN downvotes, is that EV's make no economic sense for the average car buyer. The market is choosing against them for a reason, and not because everyone else in the world, but you the EV enthusiast, is ignorant.

Personally, I think Lithium-Ion just isn't there from a cost/capacity perspective and will never get there. ICE alternatives are still forming and we'll probably look back at the crazy Tesla days the same way we look back at other oddball cars like the Delorean. Middle-aged millenials will be fixing them up in 20+ years and enjoying their kitschy value.

Heck, even if we get cost down to ICE levels (and we wont) we still have major wear issues to worry about:

The results of an Idaho National Laboratory study released in March found that the test LEAFs lost 22-26% of their initial capacity after just 40,000 miles.

So on a hot day with the AC on, what am I getting in range from a $30,000+ EV with 40,000 miles? 30-40 miles maybe? There's a reason no one is buying these things.

tldr; ICE will die someday, but it wont be lithium-ion that kills it.
That's part of the problem, but it goes deeper, too:

Mainstream America not only tells whites "this is how to be beautiful." It doesn't even come up with a standard for blacks on how to be beautiful, implying that they can't be beautiful.

There are lots of ways to take this. For example, you might say, "well on the bright side, blacks didn't have to worry about needing to look beautiful, so that's freedom for them." That's a tough argument, and requires operating at a very enlightened level.

On the other hand, you can look at some of the bold black women of the 90s like Beyonce, etc. who asserted their own standards of what beauty is for black women. You could still critique that by saying, "well, America only lets black women have a standard of beauty when rich people in Hollywood can monetize it." And I believe that would be largely correct.

It's disgusting that anyone is monetized for their skin color, black/white/etc. And the real answer is to make people think for themselves and decide about whether to live someplace based on the facts or other criteria, not whether some investor could higher foreigners to show up in a commercial. The real answer here is to make people literate about the effects of advertising so we can't be fooled. It breaks my heart to see Chinese society getting made over in the image of some of America's crappiest tendencies.

I would take the authors at their word and pay just what you are comfortable paying.

Variable pricing is really an interesting business model. I have three books for sale on leanpub, each with a suggested price of $6 with a minimum of $4. A lot of people pay more than $6, BTW, the most so far that anyone has paid is $50. Payments in the $10 to $12 range are common, but probably less than 15% of sales.
> the conclusion that black people are seen as less good looking than white people.

I dont think its about looks, its about status. White people atleast in India are considered to be rich and successful while black people who are from Africa are poor. I assume its the same in China.
McDonalds is a common dietary substitute for those with a low-income

It is really hard for me to understand this line of reasoning. I lived in Canada as a foreign student a few years ago and it was way cheaper to cook for yourself than to eat at a McDonald. Maybe the situation is different in US, but I doubt it.

I think technically you could setup a light weight server on your phone and you could get an address for it and expose it to the internet. However, that would only be for that cafe they are sitting in. Since the server would need to stay in a fixed location or keep updating the DNS everytime it moves. This would then take time to propagate, it's not immediate as far as I can remember. I could be wrong, I'm a little weak on my networking, but I believe that's why.

Electric motors don't need much service (and when they do, it's highly complicated) so there's no need to provide access to it. People occasionally ask to see the motor in my Model S, and the best I can do is point to the rear seats and say "it's under there." There's nothing on the car that you can burn yourself on that you can get to without tools.

And did you really say that there are no cheaper alternatives for an electric car than a $100,000 Tesla? You might want to have a look at what's actually available, if that's what you actually meant to say.

It's not a mistake – I see the difference and I am claiming that those lines don't exist. There's plenty of evidence for that, including the continuous range of intelligent behaviour from plants to humans. It's just an empirical fact that there's no hard line.

Of course, that could be wrong – new evidence may come to light, after all. But even so, it doesn't make any sense to say that trying to understand and replicate intelligence is deluded, just because we don't know where that line is – because figuring out what intelligence is is exactly the problem that people are trying to solve. AI is one part of that, along with more empirical research in fields like cognitive science and biology.

Are people researching quantum gravity deluding themselves because they don't yet have a hard definition of quantum gravity? Figuring that out is exactly the point!
Agreed. I was definitely expecting a reference, and I was confused that the table of contents listed the authors & their positions before mentioning the title of the chapter.
I won't argue about how we live in a terribly consumer-fixated culture - totally agree with you. Ironically, at this exact moment, I'm writing a review on Amazon, about how much I like my 15 year old Kaito KA007 hand-cranked radio. It's never seen a single battery, yet I've had it with me on camping, business trips, burning man - everywhere. 60 seconds on the crank gets me 20 minutes of radio. I hope to have it with me another 15 years.

Likewise, my Mountain Equipment Co-Op Backpack that I've had for 18 years - I've had that with me every single day for 19 years, it's my laptop case, my tool case, my document holder - In the Amazon Jungle, Luxembourg, and with Network Engineers in London, Dubai and Singapore. I've used the heck out of it - and it's still going strong.

So, I'm totally on board with having a very few things, that you take good care of, and last a long time.

But - this is a separate conversation (somewhat) from energy usage. Heat, Pumping/Processing water, cooling - they all have some physical minimum amounts of power. And even if you are living a hyper-efficient 40 gallons/day life style (Northern California, see http://www.nytimes.com/interactive/2015/04/01/us/water-use-i... ) versus the rest of the world (See: http://www.data360.org/dsg.aspx?Data_Set_Group_Id=757) - there are some physical limits as to how little energy you can use and still maintain a comfortable lifestyle. We can only be efficient so far - eventually we're going to have to find a way to provide lots, and lots, and lots of power to everyone in the world, if they want to live a comfortable lifestyle.

Thankfully, much of that comes from having warm homes, and hot water - something that Solar does an admirable job of providing (bringing it all back to the original thread).

The fact that PHP is a dynamic language and that "==" would automatically convert the types of both ends to a flat because of the "0e" prefix of the string is problematic. Perhaps it's a bug in the PHP source code.

See below.

# the examples were essentially similar like this comparison.
php > var_dump("0e462097431906509019562988736854" == "0e830400451993494058024219903391");
bool(true)

# md5() does return a string type, but just happens to start with "0e"
php > var_dump(md5('240610708'));
string(32) "0e462097431906509019562988736854"
php > var_dump(md5('QNKCDZO'));
string(32) "0e830400451993494058024219903391"

# and if PHP treats them as floats instead of strings, they all evaluated to the same thing. float(0)
php > var_dump(0e462097431906509019562988736854);
float(0)
php > var_dump(0e830400451993494058024219903391);

I think it might be a meaningfully adverse effect on obesity. There aren't a whole lot of ways to affordably meet your daily calorie needs when you're living low enough on the income scale that you possibly don't even have access to a working kitchen. I many of them are less healthy than McDonald's.
As a foreigner living for 2 years in Singapore and coming from an unstable country I can say that Singaporeans have more freedom than any other citizens in the world. Like Mr. Calvin Cheng says:

"I tell you what freedom is.

Freedom is being able to walk on the streets unmolested in the wee hours in the morning, to be able to leave one's door open and not fear that one would be burgled. Freedom is the woman who can ride buses and trains alone; freedom is not having to avoid certain subway stations after night falls. Freedom is knowing our children can go to school without fear of drugs, or being mowed down by some insane person with a gun. Freedom is knowing that we are not bound by our class, our race, our religion, and we can excel for the individuals that we are - the freedom to accomplish. Freedom is living in one of the least corrupt societies in the world, knowing that our ability to get things done is not going to be limited by our ability to pay someone. Freedom is fresh air and clean streets, because nothing is more inimical to our liberty of movement than being trapped at home because of suffocating smog.

These are the freedoms that Singaporeans have, freedoms that were built on the vision and hard work of Mr Lee, our first Prime Minister. And we have all of these, these liberties, while also being one of the richest countries in the world."

The whole article is great http://www.straitstimes.com/news/singapore/more-singapore-st...
They are providing people who do not have internet with internet. They are giving people a useful service they did not have before for free. They aren't making people use the service or pay anything for it. I don't see a negative.
It's a bit hard to answer this on mobile and get all of the links in, but there was quite a bit of controversy around these lay offs. The first was that she ordered the layoffs but reopened the same number of jobs in foreign countries, and in many cases more jobs. The work force of HP actually grew significantly over her tenure, just with cheaper foreign labor.

This is in contrast to Meg Whitman who, during my personal tenure at HP, laid off far more employees than Carly. Meg though did not try to add back head count in a cheaper way. She was just reducing the work force, which was needed. When I started HP had 360,000 employees, post Carly. (Disclosure: I was laid off from HP during a Whitman lay off).

The other thing which made Carly's lay off controversial was that they changed HPs technical ecosystem pretty significantly. For most of HPs history they had been giving employees significant amounts of equity in the company. When Carly came in there were high ranking technologist with quite a bit of voting ability due to their stock holdings. This put a real cramp on the executives ability to make decisions without those pesky engineers using logic to ruin it. When she first came in, for example, she couldn't get board approval to lay people off.

To solve the problem Carly did two things. First she diluted the value of the existing stock by merging with compaq. After that the existing power that the engineers held was diluted enough that she could make the decisions she wanted without as much problem.

This is where the quote having to do with laying people off quicker comes from. She really had to work for those lay offs by restructuring a company first. Another often heard comment from her was that a business as big as HP should never be run or managed by engineers... We have MBAs for that.

She was not well liked.
Ubuntu 15.10 Is Codenamed the Wily Werewolf
Hey this isn't a constructive comment & you'll probably get downvoted for it. It happens to me whenever I comment in a thread that mentions Node.js because of my name. It is the best, but not everyone understands.
Wait, you're comparing a NEW ICE car with 200+ range, warranty, etc to a tiny ~40 mile range USED EV with a battery pack on its last legs (battery pack capacity drops begin at around 10 to 15k and continue from there). Real world range in traffic, climate control on, etc is not the advertised number. Its not even close. Search the Leaf forums if you don't believe me.

Not to mention, after Fed and State rebates, there's $10,000 off the cost, which is affecting its resale value. Give me $10,000 for an ICE car and I'll show you a near free car with 4x the range, a warranty, etc.

Come on.
Honest question : how much of the unneeded testing is CYA against ambulance chasers?
This is nothing like the absurdities of the audiophile community. Routing traffic just isn't as trivial as you think it is, and going with cheap NICs that are missing important features and have lower-quality drivers will produce measurable and significant differences in objective benchmarks. If you have something like a 100Mbps cable connection, you can't use just any off-the-shelf hardware and expect to solve any problems in software.
It's not so much about "never nil", but rather "never accidentally null". Rust's compiler prevents you from moving data into a method which then nulls it out, leaving a dangling pointer in the calling code. At best this dangling pointer will look at garbage and cause a crash or undefined behavior. At worst, it will look at other, actively-used memory and cause a security vulnerability. Rust will just refuse to compile until this problem is fixed.

Static analysis of these lifetimes allow a whole class of errors to be avoided (dangling pointers, double-free, iterator invalidation, etc).

Rust's Options are handy for a lot of stuff (async APIs, concurrent code that may/may not succeed, error codes, etc). But they are just icing really, not really the main thrust of Rust's memory model.

> It's certainly not easier to use and reason about, IMO.

To offer a counter-viewpoint, I find that Option<> (and Result<>) are very easy to reason about. They tell you exactly what to expect from a function, and you don't have to guess if you need to catch exceptions or let them throw higher up. Everything is explicit, the only surprises are panics which are cataclysmic anyhow.

> And it seems just as likely you'll end up crashing your program due to a bounds-check error (which may happen more often since Rust encourages indexing over references due to this very design.. at least, so I've read).

If you use iterators in Rust, you never need to worry about out of bounds errors. In fact they skip range checking altogether, since you are guaranteed that the value you are iterating on won't change under your feet (no iterator invalidation, etc), which generates more efficient code[1]

If you use explicit indexing, then yes, you can have a runtime panic if you go OOB. But that's the nature of explicit indexing. It also has to include those safety checks, so will be slower code.

The tax incentives in question the remove a fair portion of the tax penalty apply to all electric vehicles, not just Tesla. The "relief" for Tesla isn't accidental.

I would say you'd be correct if the benefits applied solely to Tesla vehicles, but not in this case.

There is good GMO and there is bad GMO.

Altering the organism to improve its nutritional profile, such as by growing rice with vitamin A, that's good. I'm totally behind golden rice.

Altering the organism to resist herbicides or express pesticides that have potential toxicity to humans is a matter for some concern. The alteration itself may not even present a threat directly, but may enable an agricultural practice that causes harm.

For instance, herbicide resistant crops may absorb the herbicide, the safety of which was determined based primarily on inhalation and skin contact, and become the vector for an unforeseen risk from ingestion. Some people have made some provocative unproven claims that the symptoms of gluten sensitivity are actually adequately explained by glyphosate poisoning, mainly from crops that have been chemically dessicated prior to harvest. Obviously, glyphosate-resistant crops would not be dessicated pre-harvest with glyphosate, but they would have been sprayed with it during the growing season. I can't say for certain whether that particular chemical would be retained or degraded in any given plant. But I know that a tiny, tiny amount is present in much of what I eat. Is it dangerous? I don't know. I don't even know how I would prove it if it was. I always have the option to eat different foods, or differently cultivated foods (i.e. organic), if I so choose.

But the primary reason I'm mostly against GMO is the brutish nonsense surrounding patented seeds. The slow accumulation of possibly barely-toxic chemicals in my gut is less of a concern to me than the lawyer that orders a person to pay a license fee on each kernel of corn that he or she intends to plant. That guy is manipulating the entire market for food, changing the whole business model for farming, and that scares the insoluble fiber out of me.

The primary threat isn't in the genes; it's in the laws.

Range is why we don't have an electric car yet. They are great for urban dwellers but for people that live out 'in the country' range is a serious issue. We only go in to town once a week or so and that is a 50 mile round trip if we make no extra stops. To go to the 'city' which happens once a month or so a round trip easily crosses the 100 mile range and can top 150 miles with dinner added in. A trip to a real metro area would easily cross the 250 mile mark.

If Tesla can deliver a 'real' 200 mile car for a reasonable price it would be worth considering. But for a significant percentage of the rural population EVs are simply not an option at this point.

Still there would be no Tesla without the car industry.

Tesla has lots of same parts from Ford.

Anything from adaptive cruise control to autopilot and as such is brought in because of the partner ship with Daimler.

The original sports car was based on the Lotus Elise.

The whole manufacturing plant is build by car industry experts.

and after reading the sample I feel their definition of valuable doesn't align with mine. It's a "handbook" but the chapters are interviews that don't go in depth into anything. Here's a sample "question"

In my mind at least, this is both quite odd and yet fascinating at the same time.

It makes me think though of a Chinese intern that used to work for me. She would make comments about how "good looking" white people were from time to time, and how she thought Chinese people were ugly. When she would see pictures of my kids she would say things like, "You have the cutest children ever; Chinese kids are so ugly."

On top of this there was another Chinese intern who was quite close with her, and obviously interested in starting a relationship, but while she liked him she said she could never be more than friends because he was ugly. In reality he was a very normal attractive young Chinese man. He was friendly, well educated, well groomed, but he never stood a chance with her because she was repulsed by her own race. I found the whole thing to just be very sad.

Instead of rebooting all the affected systems, create a monitoring check that alerts the ops team a few days or weeks before the error condition (system will hang/reboot, SSL cert expires) comes to pass.

Then it's at their discretion what do (for example, decide when to reboot).
And what is gained from doing so? We must remain critical.
If they replaced all certs in their organisation because they could have been compromised, then all the replacements are likely to expire at the same time. The article isn't saying that you should wait longer, but that if you do nothing then one day all of the replacements will expire and cause a massive workload to update.

A fix would be to update those new certificates proactively, spreading out the workload and new expiry times. But also marking the calendar for mass expiry day because there are bound to be some that were forgotten.
Would like to see this mirrored in Canada.
