Human opinion of what's "beautiful" in other human faces is not entirely subjective. It has been know for a while that if you start averaging faces you end up with a "pretty" face. This is because we genetically like symmetry, and averaging out faces makes them very symmetrical.
I really like this idea, but it's the sort of thing I'd want to put in the corner of my screen while I work. As it is, it seems to require a browser window to be at least 1010 pixels wide to show all the content, which means that, however irrational this might be, I'm not going to use it because it's too overwhelming to have open all the time.

Also - a nitpick - the progress meter overlapping the vertical stripe at the left of the task list is driving a piece of my brain crazy. I expect it's a deliberate part of the design, but it looks incongruous to me (this is not /nearly/ as important to me as my first point - just thought I'd mention it too).

So then what did you use on your development machine to test your ruby apps with till now? What did you use if not RVM? I am happy that RVM exists and made my life as ruby developer much easier even if it overrides 'cd'. Also to note i never had problems with RVM. Your main reason not using RVM is poor, as if there were more options out there till now.

This is a very frustrating aspect of the experience.

After being coaxed/coerced for years to "be like everyone else", I finally learned to take this as a sign -- as a mandate -- to GTFO.

Such an environment will wear you down and eventually destroy you. The sooner you leave it, the better.

(And, if we are indeed that good, leaving may be the best way of counter-acting such attitudes, as the institutions we leave struggle to make do with what is left. If this is not the case, you've nonetheless extracted yourself from what, in my experience, is a personally self-destructive position.)
Indeed. Prepare to wait hours for newly added files to be synced, prepare for immense memory footprints, prepare for the worst conflict resolution you've ever seen.

I picked up a copy of this book at OSCON a few weeks ago. It's well-written, humorous, and a great overview of Mercurial and Git and a good introduction to Veracity.

If you have been using Mercurial or Git for a while, there won't be much new in here, but it is an enjoyable and quick read. And it could come in handy for converting those holdouts on your team still using Subversion (or, like a few people I work with, no version control at all!).
I tend to worry about whitespaces in/around if statements only when the condition is complex. SO I tend to have "if(a==b)", but maybe "if( (a==b) && (c==d) )" and may have space between the 'if' and opening parenthesis when the condition is so complex to be multi-line (but then again, at that point a refactoring is needed/natural)

"Let me tell you from personal experience, these people are doing more harm to their children than good."

The problem is that the science clearly says the opposite:

"At the end of 14 months, core ADHD symptoms were reduced more in the children treated with stimulants than with behavioral therapy. However, at the end of three years, 'medication use was a significant marker not of beneficial outcome, but of deterioration. That is, participants using medication in the 24-to-36 month period actually showed increased symptomatology during that interval relative to those not taking medication.'"

http://www.madinamerica.com/madinamerica.com/Children_files/...

"At the end of six years, medication use was 'associated with worse hyperactivity-impulsivity and oppositional defiant disorder symptoms,' and with greater 'overall functional impairment.'"

http://www.madinamerica.com/madinamerica.com/Children_files/...

"Within 21 months, 11 percent of children treated with a stimulant for ADHD developed 'psychotic symptoms.'"

http://www.madinamerica.com/madinamerica.com/Children_files/...

"Two-thirds of the adolescent patients hospitalized for mania at the University of Cincinnati Medical Center had been on stimulants 'prior to the onset of an affective episode.' Stimulants, the researchers concluded, may 'precipitate depression and/or mania in children who would not have otherwise developed bipolar disorder.'"

This is really strange. At the career fair at my school, the USPTO was there recruiting engineers and CS students. Assuming one single person with even a modicum of programming knowledge looked at this application, I can't see any way that this was issued, let alone after 4 years of sitting in purgatory(?). If this was sold to Lodsys could they sue any company that used a doubly linked list without licensing it? How would they even find out about what data structures you used in your code?

What's with the QR obsession? A new post about QR codes on HN every few days.
Much the same with Google Plus. It takes serious effort for growth and the infinite strength of 'user needs' not to clobber a good interface with lots of cruft that most users don't want.
Think of it this way; at $0.99, the buyer is paying for Amazon's distribution services and nice formatting, and getting the content for free!

No, seriously, I have a Kindle, and I would much rather pay $0.99 for a nicely formatted book managed by their backend than hunt down a poorly formatted free version. Plus it is easy for you to update the book.

$0.99 is hardly profiteering, and I feel like in standing on principal you eliminate a possibility everybody would be happy with.

Yawwwwwn!
Totally agreed. 500px's lack of an API is reflective of its whole purpose, it seems: after uploading photos, I had no idea whether the original version was stored. The embeds have one photo size. It's all very focused on being 'in the site' and on your 'portfolio.'

Flickr was the right 'kind of site' for me back in the day, and still works well as a photo service, not a destination. Google+ is a different kind of site - it's a 2011 socialmediaadservingconnecting site instead of a site with any focus or any emphasis on users creating content of value. The 'you are the product' feeling applies to Google+, whereas Flickr I always felt like I was paying for something of value and getting a relatively honest deal. And 500px feels less like a photo service and more like a site builder - something that doesn't fill my 'place to store all of my photos and export them if worse comes to worst' criteria.
On my Firefox it is the default search engine.

Seriously, I was thinking the same thing a couple of days ago when I downloaded FF Beta 6. Adblock used to be my first installed extension, now DDG SSL search is. Right after that I "fix" the fallback address bar search as well.
I work on problems (code) that can take an hour to grok, another hour to get the code state into my head, and then more minutes to surgically implant the right change. Invite me into a meeting or chatter outside my cubicle, and I'm derailed. So that's why I get most of my work done early, early in the morning or after everybody else has left.

This article presents the most blindingly obvious case. Why is it even worthy of discussion? Because folks who call themselves authorities have made rediculous assertions (Open office plans are productive), written a book and gotten the foolish notions somehow embedded. It takes an authority and a study and a published report to undo the damage.

Or we could just rebel - No, I won't work in your echo chamber.

Anyone have more information on exactly how this works? Does it mean 200+ Kg of thorium, only 8 grams of which would be used up during a car's life time?
"Stevens has worked out you’d require a 227kg, 250MW thorium engine in order to power a typical road car."

250MW is around 333,333 horsepower. A 250kW, 333 horsepower, engine seems more likely to me.
> [from the description on the site] There is no written rule to define whether a face is beautiful or if it is not, then the creators followed the principle that what is more closer to the common is better.

I initially thought this was the same experiment done a while ago where people rated different faces according to their preferred beauty. Then the algorithm would normalize an input face based on those preferences.

Normalizing just to the common face and having it become more beautiful is kind of unintuitive to me. For instance, I wonder what it would look like to run that algorithm on an already generally-accepted beautiful face and see if it became less so.
The moment your code begins to look like this

-webkit-transform: rotate(-70deg);
-moz-transform: rotate(-70deg);
-ms-transform: rotate(-70deg);
-o-transform: rotate(-70deg);

you know that it's time to either drop the vendor prefix or to hope that there will not be another browser vendor implementing the exact same functionality and again protect it behind a prefix.

I know that technically, the transform specs are not finalized, but considering this kind of consensus (even IE seems to agree), would it even be wise to change the spec again?
I'm guessing rbenv isn't meant for production. As to some of the comments about how you should never use RVM in production, it's complete crap. I've used RVM in production on multiple servers for well over a year. RVM fits perfectly in corporate environments where you have no access to the sudo command.
True, but the power of QR codes lies in the ability to embed large amounts of contextual information that's not directly related to remembering it.

Consider an ad campaign in a large city that puts up advertisements on bus stops. A savvy marketing department could put QR codes on each advertisement which direct the user to a webpage, but also include metadata about where that particular ad was posted.

Additionally, it's very popular among marketers because of the interaction QR codes drive. Generally, the process of interacting with a QR code (especially with a link to a website) opens the site automatically in my browser. That's one immediate impression. Since I'm on the go, I'm likely to lock my phone without bothering to close the tab. When I open Safari back up, boom. There's another impression. Whereas if I wrote the website down, there's much less of a chance that I'd bother to go through the process of opening it later (copying address into a browser.)

On the consumer side, if I see an ad I'm interested in, it's almost trivial to take a picture of it rather than "tap it in or write it down". One hand, a few taps, and I have both accessed it and saved it for later.

Agreed. We've been doing this with our MogoTix QR codes for some time. It's a branding opportunity, as well as a small indicator that someone's ticket is genuine.
Does it have a touch interface?
Another popular (anecdotal) explanation why this disorder is more prevalent in America is that somehow the same genetic trait that motivated inviduals to pack up and move to another continent, when amplified (after hundreds of years) is somehow responsible for hyperactivity.

Basically "the settlers were a restless folk" they all come to America and breed with each other, after hundreds of years you end up with a good number of people who are "too restless to function".

Anway that is one popular theory, not sure if I personally endorse it but it would seem to be somewhat supported by this find.

Of course the counter-point could be that doctors + parents + pharma companies are just more eager to diagnose it in America, and I can see that happening too somewhow.
There was a paper here on HN a few months back that compared averaged faces to faces with unchanged bone structure but smoothed skin; the differences in rated attractiveness were apparently negligible (and average faces with bad skin faired poorly). Averaging removes blemishes.

Cartoonists and animators have long contended that some small asymmetries enhance the emotional connection we have with a character --- think of a puppy with one ear that points up, or with a spot over one eye. Sympathy isn't beauty, I admit; I think it might contribute to attraction, though.
Those are pretty common refrains. Honestly it means nothing to me that rioters may have said them.

I think I missed something... basically it uses P2P instead of a central server that copies my data but doesn't that mean I am sending possibly private data all around the internet to other aero users, though encrypted?

Then isn't that the same situation we had in the DEFCON hacks: what keeps people from recording all your traffic and one fine day when the encryption is not secure anymore, they can simply decrypt it?

I've never looked at (or heard of) FreeFileSync ... but AeroFS offers a very simple install and clean minimal UI for setting up the syncing.

I don't have to worry about which machine has which copy of which file, or even what the machine names are. I just login and can choose which 'Libraries' to sync with the local machine -- it handles finding the correct source, retrying when I close the laptop lid in the middle of something, etc, etc.
You won't be sitting there hunched over a tablet. But you might hook your tablet to a monitor, attach a keyboard and mouse to it, and run "conventional" software.

Monitors, keyboards, and mice aren't going anywhere. But it won't be very many years before a desktop machine becomes a niche item for those who even today can't get enough power (3D artists, etc), while the rest of use are using one variety or another of portable core device with multiple IO options. (Though it isn't tomorrow, either. This stuff actually exists now, but it's bleeding, bleeding edge, as in the "cut yourself" type of bleeding edge. But still, that will fix itself.)
If google doesn't get social, who developed Google+? Too clean? I find the page very easy on the eyes and easy to use. Too private? I have put way more info in public (intentionally) on Google+ than Facebook. They make it easy. You are just making general statements and assumptions we have heard all over the internet, meanwhile, Google+ continues to delight its users.

I will say: Google finally gets social. It is called Google+
I find it a bit amusing, albeit rather sad, that you got downvoted for saying that. You're exactly right, of course... the web (that is, html/css/js over http) is NOT the only way to distribute apps, and it isn't appropriate for everything.

Unfortunately, this war has been lost, in the minds of developers in general. Nearly everyone seems to think that the web-browser is a modern day X server, and that it's The One True Way to remote out UIs or to distribute apps.

I do wish people would look beyond this and consider some other options and invest some time and energy on some of the other choices, but it just ain't happening for the most part.

Perhaps, but the use of a term like "we genetically like symmetry" bugs me. Has it actually been scientifically proven that humans have a genetic predisposition toward preferring symmetry? My google-fu turned up nothing. Isn't opinion naturally subjective, albeit informed by societal influences one way or the other?
I was less referring to the security issues, as I'm familiar with Google's efforts on those fronts, and more referring the lack of cross browser support. ActiveX sucked for a number of reasons, but one reason in particular was because it forced people to use IE even after IE 6 became the most inferior browser on the market by a long shot in terms of both security and performance. If NaCl becomes popular enough, either other browsers will be forced to add it or there will be similar lock-in issues. If other browsers are forced to add it, will every single one of them have the same security, performance and compliance with the standard as Google Chrome does?

I have the same problem. I grew up on a ranch in rural Texas. It was remote enough that I might as well have been on Asimov's Solaria for all the human company I had. Over the years, I became accustomed to reading, thinking, and tinkering in relative isolation.

Whether the cause is simply my background or is perhaps strengthened by some neurological factor, I am completely unable to filter out superfluous external stimuli.If someone is talking on the phone in the same room with me, I can't not listen to their conversation no matter how much I wish otherwise.

The people with whom I work tend to have difficulty understanding this aspect of my nature. I'm afraid I come off as rude and aloof when I put on my headphones and request to be IMed rather than tapped on the shoulder. Generally, these requests are ignored. One of our sales people actually came over and pulled my headphones off my head. My startled reaction did not go over well with her.

I'm not asocial. I like people. I just need silence to think.

I'm not going to argue that Flickr isn't dying, but they do have some things that Google+ and Facebook don't have: groups. A lot of groups are a waste, but some well-administered groups are awesome, both for the group photo pools and discussions.
