«Why does the battery needs to be part of the car at all? It clearly depreciates and is technologically disrupted on a different time frame than the car itself. A Tesla Roadster is a fine car and will continue to be for decades, if you can only refresh it's battery pack every 10 years or so.»

Cars overall depreciate on the scale of 10/15 years or so. Right now the depreciation rates are the same. It's an interesting artifact of ICE vehicles that people don't expect any car's drive train to last more than ~15 years. It shouldn't be a surprise that car manufacturers were skeptical of battery tech right up until they hit about that same magic lifetime number. It also shouldn't be a surprise that car manufacturers won't have a lot of incentive to push it past that magic lifetime number, because that would affect car replacement rates and that would affect the bottom line.

Mostly battery replacements look to keep the used car / secondary markets busy, and if we expect to see interesting innovations in battery replacements that's probably where we'll see them as more electric cars get resold to secondary and tertiary owners. (Just as we see the used car markets pushing innovations in after-market parts in general.)

You are right in that maybe leaves room for a disruption that someone might be interested in a "car for life" model where electric cars might be built far more sustainably with an ideal towards larger reuse of the vehicle over the owner's lifetime and a larger depreciation scale on the order of multiple decades.

That would be a huge game changer, and would potentially be great for the planet (less steel production alone, conceivably). It would also take a lot of work to make it happen, given the existing industry reliance on the current business model for most of a century now. It would also be one extremely huge disruption in so many downstream industries, secondary markets, etc, to the point where it may be more of a revolution (in the industrial sense, but also perhaps the war sense) than a "simple" disruption.
Excellent. It woukd be very interesting to program for that 480hz mode. Might just look real.

I am happy at 60 plus, and over 120 rarely matters. I can tell, but do not value it much.

Thanks for the interesting info!

I mean, shitting out a new high perf uarch isn't the easiest thing in the world, but you're literally commenting on an article from Huawei claiming that they had. And now Moore's law is more or less mined out, which means it's no longer a Sisyphean task to chase the perf dragon.
Well, it is. Every f*up you can have in C, you can also have in C++.
There's plenty of years left to get to hate it (I learned C++ in 1998 and have kept relatively up to date)
At a young age, and I think this extends even into young teenagers, we’re literally talking about under-developed brains. Thought processes don’t actually fully function, and particularly cause/effect, moral judgement, risk aversion, empathy, logical reasoning skills, etc.

Now even a lower mammal can learn instinctively through positive and negative reinforcement. I think the problem is significantly more complex in young humans because the capacity for complex reasoning is there but just not firing on all neurons properly. So your negative reinforcement is more likely at that age to just confound the situation than a simple Skinner box with a rat experiment suggests.

It’s certainly not the case that punishment (or we can say “negative consequences”) are never appropriate. A negative consequence should make sense in the context of the behavior.

Yesterday at the airport, a woman with a young child was waiting in a long line at the airport food court in front of me. She was scolding her child for wandering off. The child had a small backpack of toys which he was dropping on the ground and then was walking off (a few feet) and peering around things playing hide-and-seek. The mother would get angry and scold the child to pick up his bag, and stop wandering off. A few times she chased after the boy and he gleefully ran away from her.

The child was clearly not mentally capable of waiting in the line. The mother was agitated because the line was long, she was afraid of losing her place, and didn’t want to lose sight of her child in a crowded space. So she told the boy if he walked off again she was going to throw away his toys. When he did that, she changed tactics threatening that she would “spank him in front of all these people”. At that point I asked if I could hold her spot for her, and she was able to focus on her child until her turn came.

Now that’s a glaringly obvious example of a child being totally “outmatched” by the difficulty of standing in an airport line. I can barely handle it myself sometimes. But there’s a wide spectrum of misbehavior which ultimately boils down to just being beyond a child’s mental capability, which may be diminished because of lack of sleep, hunger, or something challenging that happened earlier in the day (which could be seemingly insignificant, like a friend wanting to play a different game at recess). Until you stop to ask, it’s just so much so simpler to assume they “just aren’t listening”. It can actually be exhausting sometimes to give the benefit of the doubt. More than once I’ve felt like an ass after jumping to a threat or knee-jerk punishment only to shake my head when my wife steps in and gets to the root cause. Luckily every once in a while the situation is reversed and I get a few of my own saves too.

It never ceases to amaze me how hard parenting is, and how unprepared we go into it. I like to say that kids take an infinite amount of effort to raise.
Consistency Pays Off
If you have any goals that you want to reach, consistency is key.

Do you want to grow an audience, sell a product, make a brand of your own identity? Consistency pays off. For real.

By being consistent (performing the same amount of effort in a frequent, predictable way) you'll be able to make your audience grow. It is what drives steady growth.

Don't expect this to be a quick hack though.
It is something that you need to do on the mid-long to long term.

Consistent effort lets your target audience adapt to your message. It is what lets them get known with your products and services.

My advice to maximize the efficiency for your consistent efforts:

- Keep your message real

- Don't broadcast, connect with your audience and target market

- Don't go performing sales, but provide value instead

How is not addressing the cause of the hand licking rational?
Actually, the employed women are the ones who divorce more. Unemployed women divorce less. Female employment affect primary divorces in unhappy marriages - in happy marriages it does not affect divorce. Women do pay for their portion of costs after divorce.

And of course, child is not about your needs. Funny how you don't count work in child-raising at all into expenses - the times when you have to go from work sooner daily (meaning forget about projecting passionate programmer image), the part where you are not free to do what you wish in the evenings, the part where you deal with school and what not.

For you it is all about money and parents own needs. Plenty of fathers do the above work tho, including divorced ones. Universally, they don't see the child as possession the way you talk about them.

Yes, women are on average happier after divorce and men are less happy (but have it easier to find new partner). I don't know about mothers who frequently train the children to dislike fathers, it does happen occasionally just like father who is not willing to take time away to spend it with child. However, I could see how the child that is treated as a possession by father would come to resent that.
No matter how harmful Marijuana is, prohibition is even worse.

I recently moved to a state that has legal weed. I was pulled over yesterday and the amount of FEAR I felt when the cop got out of the car was intense. I spent years being harassed by cops who would "smell marajuana."

And then it clicked in my head: I don't have to be afraid. Weed is legal. They can't use that excuse anymore.
Prior to cryptocurrency there was no way to store your wealth online without relying on a centrallized third party that could theoretically confiscate it at any time. It's niche but it's not something to overlook.
One of my favorite companies of all time, NoRedInk, hired Evan the creator of Elm full time just to work on ElmLang. I think it shouldn’t be too hard for any company relying on Rust in production to hire Steve or some of his team members.
Agreed, I've started spending more time learning rust, and the book + your comments here on HN about Rust internals makes the learning so much pleasant, thank you for those!

> It is only when she applied an irrational approach to the problem, surrendering the need to control the situation, that she could finally understand what was going on.

I feel like you have a somewhat idiosyncratic definition of "irrational" that you're applying here.

What I took from the hand-licking story was that her initial attempt to brute-force the issue without understanding it was irrational, i.e. "not logical or reasonable", and that approach failed. Then, quite reasonably and rationally, she backed off and established trust with her child, found out the underlying cause of the issue, and provided a solution that resolved the underlying issue.
In such a masterpiece as "and then there were none", which is by far the most sold mystery book ever, Christie chose to ignore 4 of these rules, at the very least. For instance (I mention this one because this is not a spoiler), there is no detective at all in this novel.

Didn't read a lot of books from Van Dine, I just remember they are very dry, because he is fascinated with the mechanics of the detective novel. I didn't like it, but give it a try, his approach might appeal to you.
It has already been weaponized. Hydrogen/thermonuclear fusion bombs are a thing and have been since the 50s.
I think it's the opposite. You're reading too much into the article. Marijuana has a reputation amongst advocates of being a miracle cure-all for all the world's ailments and no downsides.

This article is asking the question--what are the downsides?

You're instead defending against the notion of criminality.
I'm sure those statistics are entirely real and not pulled out of his ass at all.

Happiness isn't a state you can reach and just dwell in. As soon as you realize you're happy and start to think about it, it evaporates. It's a byproduct that sits in your periphery when you're experiencing life to the fullest, whatever that means to you.
A battery pack has between 500 and 1000 charge cycles, so each swap on the $20K pack will recover you $20-40 in depreciation. It's the main cost of using an electric car.

So then, the business challenge becomes to extract more value from a pack than a car owner can. There are many opportunities to do that:

- much improved inventory management, buy in bulk, monitor and adjust charging parameters etc. to prolong battery life based on observed performance of the specific battery type.

- this allows you to optimize battery purchase and chemistry to minimize overall cost even at the risk of a reduced lifetime

- centralized recharge gives you economies of scale to purchase cheap electricity during the night and enter all sorts of contracts where you can earn money by acting as a last-resort supplier at peak times, without actually using significant charge cycles on your inventory.

- the same economy of scale is passed down to customers who won't be bothered to install high power fast charge circuits, or are simply unable to.

- differential pricing based on customer needs, for example, new, top performance packs for home users and degraded packs with lower peak current for less sensitive customers, taxis and commercial fleets etc.

- batteries depreciate even when they sit charged; a modular system will allow customers to keep (and pay rent for) a single or low capacity unit on a regular basis for city use and opt for full capacity when they really need the extra range.
tbh I only read the first several paragraphs... the medical community is completely ignorant about weed and its effects. Well no shit. Marijuana prohibition was a political, racially motivated decision. The American government decreed "no medical benefit" and forbade studies except for those that had a negative hypothesis, and strong-armed the rest of the world to follow suit. So the medical community is decades behind and the drug is a total mystery. This isn't remotely news. Now that science won't be censored in places such as Canada, we might learn something useful
> I don't believe I've ever heard this phrase uttered by someone who wasn't an arrogant prick.

Me neither.
I thought the same. I mean, you don't need vast technical advancements to build that anyway, though the battery would likely cost approximately $20,000 USD with current technology. It isn't necessarily obvious that really unconventional things would need to happen to get that down to ~$10k, and most uses would work with a much smaller battery than that.

> Every bank based in London for that purpose now has to open a regulated branch in an EU member.

How many of them don't have one yet?

Also, every bank based in the EU will have to open a regulated branch in UK in order to operate in this large market.

> The number of people that supported leave and lacked understanding of all the ties of the businesses that operate in the UK but sell in the EU was amazing.

Perhaps they're just not trying to see only the drawbacks and ignore successful non-members in Europe like Switzerland and Norway.
The fact that this is true, and that simultaneously there isn't a lithium battery recycling industry of any significant size indicates that lithium energy storage is still at an early stage. The prediction that costs will come down and that the economy around lithium batteries will grow to include recycling and other ancillary aspects of the value chain seem likely to be true.
The Water Computer (2016)
From what I've heard (in Fully Charged videos), Renault did it for similar reasons and similarly expects the number of owners using battery leases instead of ownership to drop off soon as most buyers are now comfortable with the ownership model and prefer it.

You lost me at the racist bs.
I haven't heard anyone claim anything about marijuana being healthy, just not harmful enough to cause it to be illegal, and definitely not worthy of prison.
that’s really racist. what race is associated with Islam? Only someone whose never traveled and been to malaysia or pakistan or iran or turkey could lump them all as one ethnic group.
You're either underestimating revenue from Windows purchases or overvaluing that publicity bonus. There are already a lot of indie games with Linux support, and triple A developments already sell millions of copies. If that added publicity made another 1000 people buy the game, it still won't be a financially sounds decision.

Heck, I'm mostly on Linux but boot into Windows for gaming... I'd probably continue to do so, even if the games were released for Linux just for that extra performance and significantly less chance too run into an obscure issue with my setup.
>The majority of drivers really aren't qualified to tow a trailer, not even a small one.

The majority of drivers will be fine but backing up will be a challenge until they get used to it. We're not talking about an overloaded rental trailer, we're talking about a ~20hp genset on wheels.

> Just imagine the chaos of SF Bay Area residents trying to tow trailers up I-80 for a winter skiing road trip.

As much as white collar professionals tend to suck at everything even vaguely mechanical I have a hard time imagining it could be any worse than your average boat ramp. Boat ramps work out fine even though half the people there in the afternoon are buzzed.

That said, I don't think towing gensets everywhere is the solution to range issues.
Thanks for the sage wisdom. My life is changed. All right here on HN. Wow.

Hmm, not my experience. C++ was my intro to OOP but I was aware of "pure" OO languages like Smalltalk. I feel like my C++ OO experience has taught me a lot although I think it's valuable to study another OO language side-by-side. A lot of OO patterns translate between languages although the implementation in C++ is often overly concerned with static types.

Tell HN: Rackspace silently changed their cloud files pricing
Just a heads up- I've been using cloud files for several years now for around 31¢ / mo. My bill this month was $5.00 with a new line item for minimum service charge.

I received no notice they were changing this (which sucks) and I did some looking around and can't find any info on the change. Just a heads up for any other thrifty users.

For anyone else curious how it compares to S3: 600GB on rackspace is $60 / mo and 60GB is $6/mo. It's $1.34 on s3 for 60GB and $13.80 for 600GB.

Actually, Tesla's batteries don't degrade that much (10% average after 160,000 miles [0]). Turns out, with proper thermals and not charging/discharging fully vastly decreases their degradation according to other hacker news people on the topic [1].

jules is pointing out that, as EM + distributed matter is a non-linear set of equations, you can't easily give meaning to point masses. This is true, but the original implication, that the backreaction on matter is ill-defined or "shizophrenic" does not follow. This is a general feature of relativistic theories where you can not have rigid bodies.

I don't know anybody who became UNEMPLOYABLE at that time.

Sure, you might need to work under some bad conditions or take a pay cut, but that is just life. For who has great experience shit shovelling their whole life, this is nothing. For those who doesn't and can't take a crisis, they wouldn't be able to take it in any field of work.

I think there will be always well-paid work for people who are analytical, maybe you need to start over on another field, but it isn't that bad. Idk really, anything could happen, but as soon as I look around, I'm usually the most employable person ever, can speak a few languages, can do a lot of stuff, IT, development, I welcome new opportunities and things, can deal with money well and has my whole life studied finance.

I think for a lot of people on our field it is like this. I actually would appreciate if we would have a crisis, because that would be definitely the time I would be able to take part in those businesses that grow on those times and end up being huge. At the present there is a lot of shitty companies with huge valuations and providing nothing, crisis are good because they really shake the status quo and those who think outside of the box get out of it much better than if everything was perfect.

Think positive.
Thank you, Steve. You have personally done more to make the Rust community what it is today than possibly any other person. It speaks very poorly of Mozilla that they don't value your work.

Perhaps 2019 is the time to start the Rust Foundation, as mentioned by boats and others[0]. If so, you'd clearly be one of the founders. I would put my name into the ring for that as well, as we're now in somewhat similar circumstances. All it needs is some money, a lot for a pizza cook perhaps but a pittance by Silicon Valley standards.

Wherever our paths lead, I hope they continue to intersect!

Can you elaborate on what types of people you mean?
Like many a middle aged dad, I have become afflicted with boating disease. One of the many problems that comes with owning a boat is that you need some way to tow it. Another problem is that you want your boat to be as easy to use as possible. If I had an electric car I would have to go to home depot and rent a truck every time I wanted to tow the boat. This is too much yak shaving.

In conclusion, my advice as a boat owner is: Never buy a boat.
Their argument is that even if linked and distributed, there is no GPL violation for the reasons above.
Mozilla overall pays less than your FAANGs or unicorns. Mozilla is in a pretty unique position here, and so I think doing so makes sense.
I've been coding heavily in C++ for now over 2 decades, and when I interview someone I typically can get a pretty decent picture of within a general 3 - 5 year range of how long they've been coding based on the various details they gave when answering the questions about the language. And yes, of course someone could have 10 years experience, or the same experience for 10 years and never grow, but in general I found I am pretty spot on.

So I agree, 1 year doesn’t even begin to cut it. You need more than book knowledge, you need the experience of watching your masterpiece crumble under its own weight (sometimes several times) or have the joy of hunting some obscure bug because you failed to recognize the trap you had set for yourself.

I certainly wouldn't want to scare anyone off from C++, because personally I find the empowerment is worth the pain. It just takes time to learn what to avoid.
He has no regrets, but does have a basic_regret<char, regret_traits<charT>, allocator<charT>>

Welcome! As someone who’s been using C++ pretty much continuously for two decades, I think there has never been a better time to learn it. We finally have compiler competition that has resulted in robust support for the language’s great features.
