Technically the pressure gradient force, but also gravity.

http://en.wikipedia.org/wiki/Pressure-gradient_force

"A difference in pressure across a surface then implies a difference in force, which can result in an acceleration" [..] "The resulting force is always directed from the region of higher-pressure to the region of lower-pressure"

The lower pressure is the fast-moving hot wind from your mouth. The higher pressure is all the air around it. So it's like a reverse vacuum. Kinda.
Thanks for the clarification.

They should really add some info about patents and prior art on kickstarter page. And i hope , just to be sure , they applied for a patent their design.
it is far far easier and cheaper for a landlord to raise rents than it is for an established hotel to convert into residential housing.
I just want to say, it was entirely unreasonable of them to have made personal comments about you. There was a comment that compared you to a "whiner", and another that slagged off at you for no particularly good reason that I could see.

Both posts I voted down, and I hope others do also. HN is better than this. I'm sorry you had to read that crap. I wish you the best at your next startup!

>what do you mean "could replace paypal"? I use google checkout for pretty much everything I can't buy at amazon. It's accepted at lots and lots of places. and usually it's my deciding factor when selecting for two stores.

He means you're an outlier, checkout wasn't going anywhere and nobody used it, and it wasn't even international (as PayPal is).
Might be true in theory but not in NYC. There are constantly cases of illegal hotel conversions where landlords try to run their own hotels. That might be partially to avoid licensing (I know hotels in NYC need special permits) and taxes, but it's not the case that residential landlords don't want to run hotels.

> The GPU is decent for a phone, if all you're doing is 2D/video stuff.

The lack of CPU power wouldn't be such a big issue, since the real computing power of the Pi is in the GPU anyways, except that you can't actually do anything else with the GPU, because you need to use Broadcom's driver blob.

As a side note, I think it's pretty disappointing to have an "educational", "open" computer that blocks you from actually using all the hardware.

Yeah, by "login URL" I mean the URL that handles the POST, the one that's in the header.
>I would posit that Google isn't doing well in search from a quality perspective

That would only be true if there was a search engine with better quality results.

I agree that Google has dropped it's quality (compared to itself) but it's still better than anything else.

Calling him a "whiner", in any form with no substance to back it up is indeed arguing the man, not the substance of his argument. It's also mean, petty, immature, unpleasant to read and I would and have strongly chastised my three and five year old children for this sort of speech and behaviour.
Wasn't the big advantage of the Pro account unlimited storage? Do the ones with the account really store more than 1 or 2 TB? I understand that the price of the new paid account feels strange, but i don't think it is such a big failure.

I don't know if Flickr really neded just a facelift. The overhaul signals more strongly that Flickr no longer stagnates. It could be that it was indeed a needed one, given the age of the old interface. It could be that they needed that overhaul to get tumblr, to show them thay aint the old Yahoo no more. Who knows.

I agree that it gives the impression of wanting to be more hip and social, but I think that's good if the userbase was in decline before. I think that the lack of a beta and the possibility to give feedback before makes this so hard for existing users.

Delicious was something else, I think. I was under the impression that after their changes, some of the old use-cases weren't supported anymore? What is the new Flickr missing exactly, apart from tiny images as default, strange workflow to get the real image or at least bigger sizes, and ugly menus?

I know that the old Flickr wasn't a place I enjoyed. I used it mainly to get images for a program of mine. Don't think I will be a heavy user of the new one, but for my use case, it sure looks better now (iff the extended search for CC-licenced images still works).

The comparison is not really valid. The point was that one has to spend "less" time to learn Lisp's syntax.

Thus, learning binary syntax vs. decimal syntax is indeed easier, as it is easier to learn Lisp's syntax when compared to other languages like, say, Java or C++.

God everyone knows transients are awful. Hell, renters are awful (have you ever run a rental property?) People just give less of a shit about where they live when they don't have a long term investment in the place. Go live in a rental building versus a co-op and tell me you don't notice a difference. Well those people in the co-op pay a premium not to live in a rental building and Airbnb profits by destroying the quality that results in that premium.

There are a bunch of people making portable pi systems.

This one is pretty easy. It's also weirdly expensive considering the power of the machine you end up with. Ignoring the cost of the Pi - something like this costing about $50 would be great. I guess you could scavenge parts together. It's useful for some forums and very light web work. I don't know if that's evidence of the web failing or succeeding - that a 750 MHz machine isn't powerful enough for it.

Other people are being a little bit more adventurous. Here's one with a 3d printed case (http://blog.parts-people.com/2012/12/20/mobile-raspberry-pi-...) It's not as sleek as, for example, an OQO umpc but it's still pretty nice for something built at home.

This setup looks clunky, but the aim is to be powered off anything. (http://www.instructables.com/id/Port-a-Raspberry-Pi-Project/...)

Odd form factors abound. (http://www.skpang.co.uk/blog/archives/541) (fingerprints and dust would drive me bonkers with that clear acrylic!)

Here's a portable MAME system. This is interesting because of the limited keyboard. (http://blog.makezine.com/2013/01/22/portable-raspberry-pi-ma...)

Having read through a bunch of these I wish they'd start to use sleeving when they splice cables together. Little bits of heatshrink or hellerene tubing makes all the difference to reliability and neatness.

It seems the RPi is fulfilling its role as an educational tinkerer's gadget.

3.2 is important for newcomer experience IMHO; it is very common for people starting with Python to use 3.x version and wonder why the code doesn't work. It's a pity high-profile packages are dropping 3.2 support, I wasn't aware Requests and Jinja2 dropped it.

utf8 __str__ definitely caused issues for Django (e.g. `print mymodel` sometimes fails in REPL in Windows with Russian locale); people using REPL in Windows are too used to such errors so they don't complain and blame Windows for this, but that doesn't mean there is no issue.

on the other hand there are people who will accuse you of hmm... "straw manning" them even though you are not.

There are situations where instead of facing argument that makes sense your partner in discussion will accuse you of using 'straw man' tactics.

Now if you combine this with your oponent being a woman (I'm a victim of a brute male now!), you are done.

If the straw man accusation is true, it's really simple to prove you were manouvered into that using quotes from the thread. It'll just become clear and obvious.

Just hysterically yelling there : "Straw Man! Straw Man!" doesn't look serious. You take the response apart and show the dirty tacts not just call names and cry. That's weak.

> This is a basic ability I lose with centralised systems like OpenID or Persona

I'm confused. Neither Persona nor OpenID are centralized, but that might be beside the point. What sort of concerns do you have with Persona's architecture?

> I hate the idea of giving all websites a single email address to contact me

Then... don't? Persona lets you use as many addresses as you want. It already works with any valid email address, which means you can keep using all of your existing GishPuppy addresses. You can keep using your one-address-per-domain scheme with Persona. No problem.

You're right that __repr__ was not mentioned, my bad.

I think `.encode(locale.getpreferredencoding())` is awful because this changes string encoding from run to run, and because locale.getpreferredencoding() could be different (and is different by default e.g. in Cyrillic Windows XP) from both `sys.stdout.encoding` (used for printing) and `sys.getdefaultencoding()` (used for implicit type conversions).
5 Big Things from Google I/O '13
I'm all for Google fixing things and making their service(s) better.. but....

I have no idea if Wallet is better than Checkout, since I haven't used Wallet. For all I know Google made the same mistakes with that service as well.

But the biggest reason I don't plan to go along with Wallet: the complete neglect of Checkout. Checkout launched in 2006. I signed up around 2008. Want to know how many improvements Google has made to the service (excluding minor policy changes)? The answer is 0. The service never changed as far as I could tell. Google never fixed a single issue with their interface. They never fixed the major policy issues.

Shortly after Wallet launched in 2011, Google renamed part of the service: When consumers buy an item using Checkout, they are using Google Wallet. So these services are not completely unrelated. I would not be surprised if Google kept many of their policies and other problems...

It does sound like Google has given Wallet a lot more attention than they did Checkout. But I also remember the hype they gave Checkout when it launched.. and this in many ways feels similar.

Checkout could have been quite good. It could have competed with PayPal (like they wanted it to).. It was probably 90% of the way there... but instead of improving the service, they did nothing with it for 5 years.. then they developed a replacement.. and now they're telling everyone on Checkout that it's dead, and they should move to a new, but very similar service.
How is this different from people subletting rooms through craiglist or any other announcement board ?
Lisp I Programmer's Manual (1960)
That's a myopic way to look at it, in my opinion. If there is a quality deficit in search Google is in the best position to remedy it. And if they don't, someone else eventually will. As the parent pointed out, there isn't much marginal value in adding investment in an area that you are dominating. And this is almost always the downfall of market leaders.
At the very least, you might need to edit the script that handles the POST request, in addition to the login form template. We're programmers so it sounds trivial to us. But it's already way too much for everyone else, because the average website owner will not spend any time trying to locate the POST request handler in the spaghetti PHP that his nephew wrote 5 years ago (and who knows what else will break if he edits that file).

I think a common login interface is important enough that we can't wait for the majority of websites to fix even a few of lines of code. (Does WordPress even allow plugins to modify the field names on the login page? It certainly allows them to add custom headers.) Copying and pasting a "Header add" one-liner in your .htaccess file requires 10x less programming skill and carries 10x less risk than rummaging around in a bowl of pasta, so it's much more likely to see widespread adoption. We could even open a service that crawls a given website and suggests reasonable values to put in their .htaccess files, for people who want the shiny new Login button to work in their websites.

I also don't see how it would be any more difficult for experienced programmers to update a header than it would be to update a template.
I would argue for something far simpler.

The stuff about inflating with your mouth is a bit of a straw man. If you inflate say a Thermarest NeoAir or a Packraft you're more likely to use something like an Instaflator now:

https://www.youtube.com/watch?v=yJLVYfg88TE

(Thermarest have their own variant on the bag inflator for the neoair - but the principle's the same)
Or with actual wind. Scale it up, use it for rapid construction of emergency housing? An inflatable former can be covered with concrete quickly and then deflated.
My back hurts just thinking about sleeping on an underinflated mattress. More power to you if it works for you.

This is groundbreaking. Imagine ALL of your devices in your home (fans, lights, TVs, refrigerators, etc.), powered by this little board, being able to communicate with your home computer, which in turn can let it communicate with the internet. Imagine driving on the highway and you see a message on your iPhone "You forgot to turn off the lights in your balcony. Would you like to turn it off, now?"

We need more Arduino-based startups more than photo sharing sites and hipster apps. Then this world will become truly advanced!

(I'm not saying the technology isn't there right now, I'm just saying the common man needs to be able to afford this too.)

EDIT: I know the Raspberry Pi can do it already, but the Arduino will probably fit better into basic electrical gadgets like the regular fan, light, etc. I think a fan having a HDMI port (Raspbeery Pi) would be awkward, no? That's why I think this is 'groundbreaking' for the Arduino community.

I'm not sure what you are trying to say here.

Light will travel in the fastest way possible under a certain set of well known constraints. I think trying to apply this same model to how 'mathematicians' cross the road is flawed, although it is a good approximation when the start and end point are not displaced too far along the road.

As a simple counter example, think of a laser pointing along the length of a very long piece of glass. If you angle the laser slightly down, so that it hits the glass at a very small angle of attack, the laser will travel for a long distance inside the glass before exiting. It will not travel straight through the glass, but neither will it 'cross' to the other side very quickly. Regardless of the difference in the refractive index of the air and glass, you can always point the laser at an angle that causes the laser beam to travel for an arbitrary length of time in the glass.

Compare this to a mathematician walking along a very long highway. The time they will take to cross the road is NOT dependent on JUST how far they are walking. If it has heavy traffic then they will cross just as soon as their is a suitable gap. Extending the length of their journey (equivalent to decreasing the angle of attack for the laser) does not continue to increase the time they take crossing the road unboundedly.

The model is flawed for this obvious counter example, but it is flawed in simpler situations as well, mostly because the reality is that every section of road and every moment in time are not as ideal as each other for crossing the road.
I'm planning to buy a Dyson Air Multiplier heater/fan very soon so this comment intrigued me. I'll be sure to go to a store to check them out in advance. I didn't really like the video you linked as I find it to be a bit of a red flag when someone calls something "overpriced", especially when they go on to be very negative about it - it almost feels like jealousy.

Still, I'll look into it before I buy. I don't suppose you know of any other fans/heaters that you would recommend?
