OK, now I understand where you're coming from. The physical limit is that at higher speed, we must expend more energy per unit of distance, to overcome drag (relatively little is lost in braking or rolling resistance of tires.) [1] So on any planet with an atmosphere you will have to contend with this.

The 'ideal' speed isn't really even 55MPH, but lower if you had all variables at play to get the maximum MPG at any speed (probably 30-40MPH), but manufacturers expect people to cruise on the highway faster so they adjust the gearing. If you're asking how to push out the curve so that going faster than 75MPH doesn't offer a huge loss of speed, lower drag coefficients are the trick. Or switching out of the 4-wheels-on-ground automobile.

[1] http://upload.wikimedia.org/wikipedia/commons/thumb/0/05/Ene...

In this generic diagram, the ratio of drag (air)/rolling (ground) resistance is 11-to-7. As you get to higher speeds, the ratio tips even more in favor of drag.

Fun fact: The Bugatti Veyron gets 2.15MPG at its top speed of 250MPH.
Unless you run in lockstep, your distributed game is always in a persistent state of desync. It's probably more fair for both players to be desynced equally, than to let one player be synced perfectly with the server, and the other be subject to latency issues.
On the main roads, it looks like there are a decent number of fuel options, within a 50 mile radius.

Ethicists Tell NASA How To Weigh Hazards Of Space Travel
I was hoping that an article about careful use of measurement units wouldn't contain a blatant mathematical error.

The article calculates, presumably correctly, that driving 70mph costs $3.66/hr more than driving 55mph in some reference car. It concludes that driving 70mph is worthwhile if getting to your destination an hour early is worth more than $3.66.

This is completely wrong. Driving 70mph for an hour gets you 15 miles farther than driving 55mph for an hour. Doing that costs you less than $3.66, since you're driving for less time. It also doesn't save you anywhere near an hour.
This topic came up on HN a couple of years ago [0], and I posted a comment that was well received. So here it is again, edited for the present context and updated with my recent thoughts:

People do seem to misinterpret MPG ratings. A study published in Science in 2008 [1] found that participants consistently overvalued vehicles with high MPG ratings. They assigned values linear in MPG rather than linear in its inverse.

The study's authors told participants to "assume you drive 10,000 miles per year for work, and this total amount cannot be changed." The participants were then asked to come up with values for vehicles of varying fuel-efficiencies. That is just the sort of optimization problem people face when choosing which car to buy, and apparently a fuel-efficiency metric that puts the amount of fuel in the numerator makes the problem easier to solve because expenditure is proportional to the amount of fuel burned, at least when distance driven is taken as given.

But in reading many of the words expended on this topic over the last couple of years, my lasting impression is that this a lot of hullabaloo about the wrong problem. It's the lack of attention paid to the "miles" part of the equation that most needs fixing. If the goal is to reduce carbon emissions (or any of the other negative externalities of driving), then taking distance driven as fixed frames the problem in a way that obscures the real solution: we should be encouraging people to drive less.

Yes, reordering your daily life to drive fewer miles is more disruptive than simply buying a car that goes farther on a gallon of gas. And, granted, once you've chosen your style of life, minimizing the amount of gas you burn as you go about your daily routine is the thing to do (even if your optimization problem is a purely financial one). All the same, it's ludicrous to ignore the basic inefficiency of the suburban lifestyle that predominates in America while we wait for automotive engineers to come up with clever solutions to pricey gas and to carbon emissions that are twice as high per capita as in similarly wealthy countries.

Elon Musk isn't going to save us all by himself. Surely living closer to where you work, using mass transit, cycling, and walking more must be part of the solution as well. ... So maybe houses and apartments should come with a "miles per day" rating suggesting how far you'd travel getting to and from shops, restaurants, entertainment venues, and your place of work every day you live there. ...

the whole thing is: in her preliminary study, people with more male-hormones (layman term) identify depth by shapes in motion. people with less (or female-hormones, again, very layman terms) get sick when there is no light hinting on that 3d body movement.

You don't even need an oculus to test the hypothesis. it can probably be tested by:

- showing that spinning woman shadow that everyone sees spinning to a different direction, see if women get sick/annoyed/react in any manner faster than men. or;

- put lots of people in a room with a hanging light as the only light source, kick that light in a large pendulum movement. check if the women get sick faster than the men.
Right now local transit in the US is often less energy efficient per passenger-mile than a solo-driven Prius or Insight, or even the average-loaded (gasoline) passenger car. The numbers vary of course based on passenger load and route efficiency of course.

Dear gameraddict,

First, don't blame yourself for it will do nothing but send you into a spiral of depression.

Second, learn some self control. Start with small promises to yourself, keep and repeat the promises. You have to do it everyday, at the same time; rain or shine.

Three, you're working for yourself so you set the time when you work and when you play. When you have a plan, apply second.

Four, there are many types of people. Some people are better in the office. Some are better when they work at home. It is obvious that you do not work well when you are at home, so GET OUT. Go to coffee shop or join a co-working space.

Five, punish yourself. Since you answer to no one (except for maybe your clients), you need to be able to punish yourself. For every promise that you couldn't keep, you can't play for the entire day.

I was in a similar position as you are. Although I didn't quit my job, but I do have a lot of side projects. At the time, when I was working all I could think about are the games and what sorta of things I could be doing (i also play diablo). I would deliver the projects late and would always have some stupid excuse about it. In time, I was very bitter, dishonest, and not very happy with myself. I did some research and read up on game addiction or other bad habits and put together the list above for myself. It was really hard the first 2 or 3 weeks, it was even harder compared to when I quit smoking.

Over time, I am able to be very strict with the use my time. Now my fiance is complaining that Im too mechanic about it.

Hope you are able to overcome this. Good luck

This was flagged by users. On the other hand, the article is clearly substantive. As an experiment, I'm going to provisionally turn off the flags. The thread hasn't degenerated into a flamewar so far; let's see if we can keep it that way.

All: please take extra care to make your comments high in substance and civility, and as low as possible in flammability.
Great comment. I'll add an observation:

we should be encouraging people to drive fewer miles

To do this we basically need denser neighborhoods, as Edward Glaeser points out in The Triumph of the City (http://www.amazon.com/Triumph-City-Greatest-Invention-Health... he points out, as does Matt Yglesias in The Rent is Too Damn High, that the big problems are with local zoning requirements, which by and large forbid density increases.

There are lots of local battles going on regarding density, and I agree that these are good things: "living closer to where you work, using mass transit, biking, and walking more," but they can all be encourage or discouraged by zoning. In most of America they're discouraged.

In the meantime better mileage is at least an improvement.

I get that I live in a bubble surrounded by only tech news. But when I was in school I knew plenty of women in nursing and it seemed as though the lack of diversity wasn't keeping them up at night. The median nursing salary in the bay area is definitely competitive with and possibly better than programming.

I also get that there are plenty of dudes in tech being giant assholes or chauvinistic or sexist or misogynist or whatever other words you'd like to call them. But why is that so much more of a problem than the obvious sexism in other areas? What I mean is why is there a NYT article on male computer programmers behaving badly and not one on male welders behaving badly? I'm not suggesting that either one should get away with it, bad behavior is bad behavior. But why is it newsworthy in tech and not in welding?

You're not alone, but I agree that it is odd when the age of your life-stage peers trends much higher than your own. getting married early on and having kids seems to be something many people don't consider until their 30s now.
There is certainly nothing easy about it. I have quite some experience with low-level and embedded devices, but hardware has progressed to the point where a Cortex M3 is quickly becoming the jellybean baseline throwaway uC, and have you seen the datasheet of one of these things?

The amount of stuff they do is incredible, and everything is interconnected in unexpected and intricate ways.
The article isn't really referring to the Oculus Rift in particular, so much as the gender-linked nature of depth perception. That's an underlying technological issue, and not something you can fix by dropping a few grams and giving it a paint job.

It's a bit of a linkbait title, because it's quite misleading in that it suggests (especially to the large fraction of people who read the title without opening the article) that Oculus is engaging in some institutional gender-discriminatory behavior (an amusing perhaps autoantonym is that an equivalent title might be "Women don't use Oculus Rift, but it's not sexist!").

Just as easily, the title could have been "Is Avatar sexist?" (I'm actually really curious if 3D movies also induce nausea that differs in rate along sex/hormonal lines, and I would have expected, given its mass-market nature).

From a pretty shallow search, I found http://www.pacificu.edu/vpi/publications/documents/OVS.3DVie... which claims that there isn't a link between gender and anything (nausea, dizziness, disorientation, blurring were all found to not correlate) except for "involvement in the movie".

The thing is we have a lot a lot of leverage on the technological side. Choosing a behavioral and societal change vs. technological is always a trade off - but for this case some things make improving the technology much easier. The median age of a car in the US is about 11 years vs. 36 years for homes. Cars are individually replaced whereas reconfiguring homes that are on fixed land is a much more difficult task. If you're asking about an individual level I agree it's a choice, and you've covered those pain points say within a metro area. However if your family is in many South/West cities - say the Houston metro area or Las Vegas, distances are going to be pretty far. Amazingly, Los Angeles actually has pretty low average miles per year - one of the lowest for metro areas.

While the technological advancement is pretty much a universal win, the behavioral change isn't, or is at least debatable/not everyone's cup of tea - a lot of Americans prefer to live in large houses with lower density neighborhoods (of course others prefer large dense cities). Many also live in rural or semi-rural areas, and the US has a lot of cheap land compared to say Western Europe. Zoning in a city is dictated by those residents. However with better technology and cheaper energy, the expense of this lifestyle will be lowered and allow more choices (similar to how remote work allows people to remove geographical limitations). If we think about developing countries, any efficiency gains will also reduce their energy impact as consumption increases
As a consumer, RetailMeNot is great. As another website that sells products for commission, it's terrible. If RetailMeNot can find a coupon that I fail to mention, that's fine.

But RetailMeNot also steals that last click cookie with coupons that simply do not work or are not really coupons (Check out the Amazon Free shipping "coupon" for example). That's nothing but cookie stuffing, and if it were any other smaller company doing something similar they'd probably get banned from the Amazon affiliate program.

Basically, imagine you as a website owner buying a product on Amazon and writing a review about it, reading the review out while piecing together a video montage that shows it off, taking some pictures of it, and compiling it all just to get a little bit of commission if someone reads and watches your review. Then the customer searches for an Amazon coupon before checking out, goes to RetailMeNot, and then gets the "Free Shipping on 35+ deal" that is not even a deal or coupon, or even a coupon that does not even work or exist. This million dollar company has stolen your effort and will get commission on that sale. It's just rotten from that viewpoint.
I have no doubt that affiliate networks will move into multi-click or other more dependable attribution models.

I would be more afraid of changes in attribution than getting slapped by Google.
Business people in tech get no respect from the purely technical folks. "Every" programmer hates their PM.

Yes it's a generalization and thus false by definition. But there's a lot of truth to it. Project Managers are a nicer way of saying "boss" or "manager" in a lot of ways even if they don't hire & fire and thus yes, there are tons of people who don't like their boss.

Sure PMs are supposed to be more west-coast management style and delegate and herd cats but there's always shitty work that SOMEONE has to do and thus they end up having to do the east-cost top-down style stuff from time to time. And that engenders negative feelings no matter the sex of the person.

Business people get no respect because when asked about business logic they'll reply one way "definitively" and then 3 months later -- when it's critical for them to make a deal -- they'll change their mind about a thing "that will never change" and make extra work for a programmer. Programmers, being lazy by nature, hate this and that's why business people "get no respect" in tech. From the tech folks, not from management or broader society, but from the people who do the technical stuff.

This essay really drove that point home for me:

http://www.maa.org/sites/default/files/pdf/devlin/LockhartsL...
My problem is that I don't understand the article. It violates everything I learned at the university I attended.

Apparently it uses a form of socialism that really isn't socialism but uses that name because they cannot think of a better one.

But I have to really ask this very important question, what does socialism have to do with hacking or startups? It is more to do with liberal politics than hacking and startups. It is almost as if Hacker News got over taken by politicians pushing political articles and agendas now.

That is part of my anger and frustration, I want to read articles about hacking and startups, not politics. Politics has ruined the STEM industry! Politics has caused 90% of startups to fail! Politics ruins almost any technical news site that I frequent. On Hacker News here, I see nothing but political themed submissions making the front page that have nothing to do with hacking or startups. Is this MSNBC now? Is this Huffington Post now? Slashdot and Cnet did the very same things, and I ended up leaving them for that. Politics ruins everything!

It makes me so sad I want to just kill myself in a shotgun suicide!

I am curious if the users who flagged this have a lot of karma, or if they clicked through or spent an appreciable amount of time before clicking a different HN link.

I can't imagine anyone who actually read this article flagging it. And I doubt the hypothesis that it was wise users trying to avoid a flame war. Occam's razor - seems more like a knee-jerk reaction to the word sexist in the title.
I imagine it's the title of the article, which doesn't reflect the sex-linkage of depth perception discussed in the article, and instead implies malicious intent of Oculus.
The words Oculus Rift sound like a sexually transmitted disease, so who knows?
The title makes me feel like the author is trying to linkbait.
>Considering that most elite universities started as male only and have taken a long path to inclusion,

Neither of your conclusions follow from your premise.

Curious how the author knew to seed the backdoor'ed Notepad++ before Bill clicked the link?

I suppose you could just serve up a fake backdoor program for every *.exe\msi download, and remove the honeypot on the second download? The first download would execute and maybe do nothing (or error) - prompting a second download which led to the real thing.
It's not just the memorization that bothers me, but the belief that there is only one way to do math. I've been in many arguments with parents before that their (and my) kids should learn many algorithms for even the most basic things. Do subtraction by complements sometime, rather than the standard algorithm. Playing with numbers is way more fun than repeating the computations.
This doesn't sound like the Oculus is sexist, so much as that men are more predisposed to experience the 3D effect biologically. How is that sexist?
Point taken. I deleted the hypothesis, which was extraneous anyway. It's not obvious to me which interpretation Occam would favour, though. HN has many fair-minded users.
"But the book doesn't mention either technique..."

As other commenters are pointing out, the book's aim is to
teach imperative programming with C to students of SML. It is not aimed at teaching functional programming in C.

The technique you describe -- using what UNIX offers, e.g., pipe and fork -- is used a lot by djb.

This book seems like a gentle intro to C.

And there's nothing wrong with keeping things simple in the beginning.

With respect to books and tutorials on C, I have seen much
worse.

Master the basics of C, then go read djb's code for lessons
on how to structure programs and smartly utilise what UNIX
has to offer. Keep K&R and Stevens nearby for reference.

A classic example is passing file descriptors instead of using a pipe function that opens a shell. There is no book on C that teaches that, but it is elegant programming indeed.

Even when one strives to keep things simple, C (and UNIX) have many gotchas.

There's a lot to learn.

This book doesn't overwhelm the reader.

Personally, I like the approach.

Lots of short consistent examples.

Lucid writing style, too.

Cold turkey and uninstalling works well. In my case, anytime I wanted to game, I'd get a prompt that the 10gb download would take 12 or 24 hours to reinstall. I was looking to game that instant, not tomorrow, so I wouldn't bother downloading. It was a small barrier, but it prevented games from being available at the click of a button.

Let me ask you a couple of questions...

1. Do you want to take a break from work right now and play a few games?

2. Do you want to play games tomorrow?

Uninstalling games, and forcing them to be redownloaded changed the question from number one, to number two. Like most people, I aspire to be a better person tomorrow, so it was easy to say no to question number two, and redownloading.
