Historically, successful men didn't need great relationship skills. They married a woman for that. She brought those things to the table as part of her contribution and he paid the bills. Division of labor.

Women who are college educated, good looking, etc. do not de facto have awesome relationship skills. In fact, you can sort of bet on the idea that if they put their career first, they have probably given short shrift to such things.

The assumption that women who are educated and have successful careers make "great catches" flips the historical standard that what made a man a great catch was his career (not just for the money, but also for the kind of lifestyle that came with the career -- the social circles you run in, among other things) and in order for this to work, men would need to take over the role of tending the relationship: the cooking, the cleaning, being supportive and a good listener, etc.

And that means women would need to start looking for men who invest in that more than their career. They would need to start marrying down.

In essence, the assumption that a woman is a great catch if she has a serious career only works if men are willing to take over the role of "wife" by the droves and the career women are willing to make that deal. Most women still want men who are their equal or superior in terms of career success and income, as the article makes clear.

This isn't a shortage of men. It is a legitimately hard problem to solve to have two career people hook up and also make the personal life part work. A two career couple with kids and a social life, etc. -- there are only so many hours in the day. So this tends to not work.

I have read many, many articles wondering how to make this work and, for me, I think the answer is "My kids are grown adults and I am hitting menopause, so no more babies for me." That means it gets a lot more realistic for me to have a career and also a man in my life with a real career. When you are looking to have a family and make sure all members of the family are properly cared for, it's wicked hard to also have both parents pursuing a serious career with the pedal to the metal.

So I would say these women are choosing career over private life and the law of large numbers mean some of them will just have that career they put everything into. I get why women make that choice. I get why it is hard to be financially dependent upon a man, etc. I did the homemaker and full time mom thing. I know how hard that is. But when push comes to shove, if you just have other priorities, you simply may not get to this one thing that is lower on your list of priorities. Duh.

Depends what you're preparing for.

If you're preparing just for a few days/weeks without "the grid", then obviously the most useful items are everyday consumables:

- toiletries: toilet paper, tampons, razors, soap, toothbrushes, toothpaste (although hard soap works as well), lenses & glasses

- medicine: antibiotics, plasters, vitamin C (and other vitamins), water filters or water purification tablets, first aid & trauma kit

- heat & light: lighters, matches, candles, flashlights (including headlamps and wind-up flashlights), batteries, solar chargers, clothing, gasoline, portable generators

- entertainment: radios, books, board games, alcohol, cigarettes

- food (obviously): rice, flour, pasta, honey, canned meat, canned & pickled (or otherwise preserved) food

Especially noteworthy are cigarettes (or cigarette boxes); IIRC, there were historical examples of societies using cigarettes as money - cigarettes are rather small and light, last for a long time, are hard to falsify, easy to verify, and have real-world utility.

For long-term "lawless" society, other things would be useful as well, such as seeds, guns & ammunition, communication equipment (walkie-talkies), books that explain how to do stuff ([1], [2]), all kinds of tools, instruments and equipment.

WARNING: all of the above is purely theoretical.

Women also tend to earn less money, being dependent on their husband's income for much of their working-life. The SSA has actually studied this issue, and women tend to be much more likely to exhaust all other forms of retirement savings and subsist exclusively on Social Security benefits: http://www.ssa.gov/history/reports/women.html

Life is too short to deal with the alternative.

It's potentially contradictory: the alternative is upgrading your OS and find pretty much everything where you left it, instead of having to reinstall everything. I.e. life is too short to spend time reinstalling everything.

Surely, it's an opportunity to do some cleanup of unused stuff, but otherwise, I haven't had a lot of problems upgrading OS X. (nothing memorable at least)
This sounds a lot like longevity insurance (a form of deferred annuity) which from what I've read is available now. Normally when you retire (with a decent size 401k or IRA balance), you have to take a guess at how long you will live, and draw it down at a rate that will last you. The safe bet is to guess you will live to 100, and that the fund will grow at 4-5%, but that may not leave you with enough annual income.

The idea of longevity insurance, is you buy something like a $50K policy at age 65, and the insurance company will pay you $70K a year for life after you turn 85. So you buy the policy up front, and adjust your 401k withdrawals so that fund runs out a age 85. Then the annuity takes over after that.

It simplifies managing storage for users. Per Matias Duarte, who I think was Director of Android User Experience at the time: [1]

Everybody likes the idea of having an SD card, but in reality it's just confusing for users.

If you’re saving photos, videos or music, where does it go? Is it on your phone? Or on your card? ... We take a different approach. Your Nexus has a fixed amount of space and your apps just seamlessly use it for you without you ever having to worry about files or volumes or any of that techy nonsense left over from the paleolithic era of computing.

Remember the vast majority of users have vastly less technical understanding than HN readers.

On the contrary, Xeon Phi has absolutely been a move to get some of the hot GPGPU market, and it's not working very well. AFAIK they don't have any cases where they beat GPUs on performance per watt (or per hardware dollar). So it's highly accurate to say they can't build something better than a GPU (so far).

Impala has an in-memory columnar format on its road map for 2016. Is that format being design with Kudu in mind?

> The vast majority of comments aren't worth my time (or anyone else's, but they can speak for themselves). In other words, there is much room for improvement and I hope that is Dan's focus.

The vast majority of comments are addressed to the user to whom they replied. This is the conversational nature of forums, and it's not a sign of poor quality. We're here to discuss things, not post articles to one another.

If it reduces the amount of (justifiable) complaints about banning and allows legitimate content through even in a few cases then it does help to separate signal from noise.

Some states (forget which I was driving through) have posted minimum speeds on highway.

Others I'm sure there is a generic lower limit "clause".

I've never seen a state that didn't have a "at a speed safe with current rode conditions". So, that you can still get a ticket going 65 in a 65 but there happens to be a blizzard going on.

I doubt any state requires you to go exactly the posted speed limit.
In Missouri, we have signs posted where the Speed Limit is 60 or 70 and the Minimum is 40.
I know Elon Musk gets a lot of flak for throwing out unreasonable predictions, but I watched this interview a couple of days ago and didn't think much about the claim because it was an off-the-cuff guess instigated by the interviewer.

It wasn't like Elon made a special announcement to tell the world about this. The press picks up anything he says and makes it into a big "announcement". I saw several headlines that made it seem like an official announcement. I guess he should be more careful when he's thinking out loud.

iOS 9 Time bug breaking two factor authentication
The iOS 9 clock issue previously discussed (see https://news.ycombinator.com/item?id=10262244) is a lot worse than originally indicated.

Our devops team are seeing users who can no longer authenticate using 2FA code generators because their phones are off by over 30 seconds. The offset seems fairly random - a quick poll in our office shows that it appears to only impact iOS9. Mine is off 3.7 seconds. The biggest offset I've seen is 41 seconds.

Reboots, setting manually and the n going back to auto etc don't fid it.

You can check your offset at http://time.is or by downloading the free Emerald Time ntp app.

Any suggestions for a workaround greatly appriciated.

True, but looking at the trend in energy density improvements in Li ion batteries, it's linear and seems like it would take more than 2 years to achieve a 2x improvement: http://www.batteryuniversity.com/images/parttwo-55h.gif

The problem with reducing the mass of the non-Li portion of the battery is that all of the practical candidates for the anode are metal oxides (e.g. Co, Fe, Mn oxides). Unless the whole metal oxide motif is replaced, you can't really achieve significant mass savings. There are research groups and startups working on alternate anode and cathode materials but there are tradeoffs in power density and safety. Also given that these approaches are still in the research phase, it'll take at least a couple of years before they reach commercial testing.
If the employers produce no value, then we should get rid of them. If they are producing value, then the overall value produced should be greater than the sum of the value produced by their employees.
But a separate die means bandwidth and latency of CPU-FPGA communication is greatly reduced. So if data has to be constantly moved between them, it might be a disadvantage.

Good suggestions, I didn't know about the Clip or Rockbox until now. You wouldn't happen to know any way to listen to Spotify on a similar device do you? I don't have any mp3s as I've been using Spotify for years.

Right now my solution has been to have a super cheap/small Android phone, install Spotify, and use it in offline mode reconnecting at least every 30 days. I got the phone for like $15 on a Radioshack sale or something.

> Minimum speed limit? As far as I'm aware, in the US you are supposed to go the posted speed.

The posted speed is usually an upper bound (though in some cases only a presumptive one, not a conclusive one, the way the law is actually written.)

> You could get a ticket for going slower if you are impeding traffic trying to safely go the posted speed.

You can get a ticket for impeding traffic, but usually going slower than the limit is not sufficient for that. (And may not even be necessary.)

> Are there roads in the US that specifically allow a range of speeds (beyond the variation seen because human drivers don't follow the law)?

Every highway (which is much broader than freeways) in California that doesn't have an expressly posted minimum speed limit, plus every one that does have an expressly posted minimum speed limit that isn't identical to the posted maximum limit. (California Vehicle Code Sec. 22400 allows a minimum speed limit to be established and posted -- which is still, where established, a soft limit -- and provides a violation for impeding traffic with or without such a limit, but does not set the posted maximum speed limit as a minimum speed limit, soft or otherwise, where no minimum speed limit is posted.)
It sounds like a joke, but there are so many times I wish I had something like this near my office!
EVs are just plain better in a lot of ways, even if you ignore CO2 emissions and other pollution and the whole "green" thing entirely.

Obviously opinions will vary from person to person, but a lot of people already consider Tesla's Model S to be the best car out there, not as an environmentally-friendly EV, but just as a plain EV.

If gasoline magically became 50 cents/gallon tomorrow and was sourced entirely from carbon-neutral and environmentally-friendly places, I certainly would not trade in my Tesla for a gas car just because of that.

The problems with EVs at this point are range, cost, and charging infrastructure. Range and infrastructure are negligible problems for Tesla for many people right now, and are being improved constantly. Cost is not negligible for most, but that's being addressed, slowly.

This is how new approaches enter. They start off with something that's very expensive but clearly better, then work their way down. For some reason it took Tesla to do this, rather than one of the existing car makers.

An aside regarding ethanol: this is widely regarded as a complete boondoggle in the US with no environmental benefit whatsoever, because ethanol takes about as much energy to produce as you get out of it. It's only carbon neutral if you completely ignore all the industry that goes into agriculture.

Yep, I've been taking part in those design discussions. We hope to have Kudu tablet servers support generating this in-memory format in shared memory as the result of scans, so the Impala server (client from Kudu's perspective) can directly operate on the data. We're expecting a 20-30% speed boost from this for some queries, though haven't done any tests at scale of the prototype.
While I certainly can't prove your comments any other way, my point isn't to declare that I somehow know what Amazon is going to do with this, rather that there are a lot of interesting possibilities when you control the whole process, including the final delivery step of getting a product to the actual customer. There are things you just can't do when you are contracting that through a normal courier (UPS, FedEx, USPS, etc etc.).
I say the same thing about hashtable lookup. See this thread and the linked Reddit one[1].

To answer your immediate question, the "general computation model" assumes constant memory access time. It's hand-wavy, but at least it's consistent.

The bigger problem is that for hashtables, even under ideal, non-physical assumptions, you still can't logically derive O(1), because there are unavoidable, inherent computations you have to do as the hashtable gets arbitrarily large. Either you a) adapt the hash function to have a bigger output, or b) you allow values to stack up in each output slot. a) is log(n), b) is n.

I don't know anyone who could read the hashtable implementation, without knowing the "right" answer, who would reasonably say "oh, that's O(1), obviously".

it feels a little silly to say this out loud, but I'm convinced that what Steven Wittens is doing on the web is some of the most advanced and incredible stuff I've seen since the original chrome experiments came out. Every time I read something on acko.net I am flush with both envy and wonder at how someone can command a browser with that kind of deftness.
crashes aren't really an expense. If someone causes $3000 worth of claim their rate will be increased such that by the time it's back to it's pre-claim level the difference between the pre-claim rate and increased will be approximately the amount paid. Don't believe me? Run the numbers.

It's medical stuff that actually costs the insurance companies money. Look at modern cars. The engineers aren't the ones drooling over 10+ airbags. Setting of 10 explosions close to people in a safe way is a PITA and the hardware takes up precious weight and space that could be used for something else. Consumers aren't demanding cars that get crushed like a tin can totaled out when you get rear ended at 10mph or back into a pole. The "safety at the cost of all else" designs that have been creeping into cars do keep people out of the (expensive) hospital but at a highly increased cost of ownership and with sacrificed performance in other areas (including efficiency).

There are fully autonomous vehicles today! Driving right now in all probability. For Tesla to copy/buy/partner with them sounds totally reasonable to me.

He did say regulators would take another 1-3 years. So 4-6 before, you can "operate" an autonomous car.
