I seem to remember reading this was the main sticking point. Apple didn't want to do any cross licensing while still paying a low royalty.
Just curious...will you be paying the retailers up-front and dealing with the customers or just be a middle-man and the retailers receive payment as the customer pays?
> Are you saying it will never potentially be a cure?

Well, I'm saying that the alt-med scammers can come up with 500 new 'potential cures' in the time it takes the real medical world to test one.

And that testing requires so many resources, especially in terms of the time of skilled people who should be doing something more likely to be productive, that it will likely never be done.

This reasoning applies more to stuff that's obvious nonsense, like everything that has suppurated out of the festering wound that is homeopathy, but everything goes through a period where the default reaction is skepticism. That's called science. That's what works.
Thanks for this. I ran into a lucky coincidence: my GitHub account is exactly 1000 days old. It's surprising that I've been using GitHub for almost 10% of my life. (I'm 10,095 days old, so it'll be exactly 10% the week after next.)

I love Dr. Seuss... just a quick note to anyone who is a fan of his, the last episode of South Park pays a nice homage.

But the one written work that really gets under my skin, in the vein of being a spectator vs. participant in life... and this might be cliche, but it's Pink Floyd's song Time.

...Kicking around on a piece of ground in your home town
Waiting for someone or something to show you the way...

...And then the one day you find ten years have got behind you
No one told you when to run you missed the starting gun...

...The time is gone the song is over, thought I'd something more to say...

But then it goes on, yet there is a shift in tone. Instead of worry, it is utter resignation.

What I find particularly interesting is this was written when the band felt they were losing relevance - by this point they had a run as long as and were about as old as The Beatles when they had broken up. A rock band back then entering their 30s who hadn't really broken out was doomed, right? What examples to the contrary were there? Yet Dark Side of the Moon is where their life as cultural icons began. Time is the only song on the album credited to all four members of the band.

I'm 36 years old and spent the first 15 years of my professional life working in the enterprise doing C++/C#, with all the wonderful trappings of Office Space. I'm proud of some of the work I did but overall I was pretty unhappy.

5 mos ago I quit my job to become a contractor. I do Rails work for a couple long-term clients based in NYC. This might not be a big deal to most people here... all I can say is I've never been happier. It's like, "I did it. And this is just the beginning."

They say it takes only 21 days to cultivate a habit. They also say major life decisions can happen in an instant, like a flick of the switch. I don't know how much of that is actually true, perhaps it's best to not ponder things like that too much.
> no amount of education can change the basics of human nature

When was the last time you saw someone nail a cat's tail to the ground and pelt it with rocks? Back... oh, not that long ago, evolutionarily speaking, that was just the height of entertainment. The absolute limit.

Now, only a few generations of First Worlders not having seven kids and getting to keep two, a few generations of public education and most people knowing how to read, a few generations of not starving because of locusts or drought or Act of Monarch, we have a population of people even the /b/-tards of which will step in to defend a cat.

It takes a long time. It is a long, slow, agonizing crawl. But we are making it.

Yes, it's an arrogant post.

As The Dad says: "Anyone who thinks they know what's best for 300 million people is a titanic asshole. So we're just voting for king of the assholes."
It happens the same with "change" and many others.
If what you mean is there a CDN for the Ratchet javascript, I don't think so. If you go to the website http://maker.github.com/ratchet/ there is a download link, but my repo just augments what you get in the download folder... like I said, 5 minutes :)

EDIT: I see what you mean now, no I didn't put up a hosted link since I just developed the one screen during a 5 min break. That's a decent idea though, maybe I'll make a full demo application (maybe I'll make it a Todo list, no one has ever used that for a demo app before) and put it up on Heroku.
Also, the chording behavior has a timeout between keypresses. So if you type "a" & "s" quickly (intending them to be separate), it is interpreted as a single "as" chord. You have to wait a bit after each keyup.
I would be the middle man but I would have a contract with retailers where if customers did not pay then I would pay their part and that customer would be ban from the site...my thought is retailers would feel more comfortable if it less of a risk for them also customers would only be able to do one payment plan at a time to decrease the risk on my side
Looks awesome at the first sight.

But then when you think harder, a big design flaw is that you need to put ten fingers on this keyboard to locate the keys correctly. You will have hard time use only one hand, let alone two fingers.

Syntastic for vim.
Tyson is correct in that it is not politicians that are the problem.

But I don't know that there is something inherently wrong with the voters either.

I think it is the electoral process that does not represent voter's interests. I can't select who will represent my interests. I have to pick between two false choices.

And then ALL of the power is handed to whoever wins the popularity contest. And then my concerns are ignored for four years.

Proportional representation would solve that problem. You can even use it in the executive branch (Switzerland does).

THEN Tyson could say the mistakes are our fault.

Sorry! This is a very subtle process. If you analyze it superficially, it makes sense, dig deeper and it's confusing, and then dig still deeper and it makes sense again.

When you cool the air by mixing it with water spray, a good portion of the energy is now spent producing low temperature water vapour. So... how do you recover that energy? You'd need to condense the water vapour to get at the latent heat.

You're right in direction but not in magnitude. There isn't much vapor produced, because the saturation vapor density is very low. Initially it evaporates, this cools the air before compression, and then it saturates. Any additional vaporization is recovered, because it condenses on expansion.

And if you do recover the heat by condensing this vapour, it is low grade heat, which CANNOT be efficiently converted back to mechanical power or electricity.

Also, interestingly, low grade heat can be converted into energy when you have a source of compressed air. This is not a full thermodynamic cycle because at the end of the expansion, you've also expanded air.

One of the best ways to see this is to imagine an energy storage system that's a giant Carnot cycle. The energy out/energy in is T_exp/T_comp. This is higher than the Carnot efficiency -- because it's not accounting for the energy in! The Carnot efficiency is E_out - E_in/Q_in which is 1 - T_c/T_h, the familiar expression.

Your web site claims 90% of the "grid" energy goes to heat storage. AFAICT This is NOT POSSIBLE if the heat comes from air compression. Is this an error in presentation? A fundamental error in your concept? Or am I mistaken... please explain.

Actually, if the compression is isothermal (and it's an ideal gas), 100% of the energy from the grid is turned into heat, and the energy state of the air is constant. U = 5/2 NRT.

Likewise, upon expansion, 100% of the energy comes from the heat.

The state of the air changes, but not in energy -- in entropy. As the air is compressed, work is added at teh same rate as heat -- and entropy, is removed.

Parent's syntax highlighter was turned off.
The awesomeness in my opinion is that a) this took me literally five minutes which means that I had to write absolutely none of my own CSS classes for mobile prototyping, the wonderful guys who developed Ratchet did that for me already! Also, Ratchet is not an MVC framework, it's a front-end iPhone targeted mobile prototyping framework. It allows you to prototype a mobile UI with HTML/CSS/JS faster than prototyping in native Objective-C. At first glance, I honestly think these guys are being humble by calling it a prototyping framework. I could see myself using this for mobile web versions of my apps, although that does presuppose that everything "works" pretty closely to the level one would expect it to reading the docs on their homepage. Check out the link I posted in another comment, you might be confusing Ratchet with something else.
In this case, I suspect jwz's commentary and re-post of it is as much "the story" as the rant in the original source.

Elite: Classic 1980s game to be 'kickstarted' with sequel
We get a higher energy density per m^3 of air at higher pressures. We were aiming at 4500 psi eventually.

We aim for it not to be noisy -- any noise from high pressure air rushing out represents wasted energy. Sonic booms from exhaust have this problem in automobile engines, we avoid it.

Lithium ion is indeed much more dense :-)

Consider that every car has a gasoline tank, many houses have fuel oil, and we undergird our streets with natural gas pipes, which burned down San Francisco. I submit that air has its safety issues, but that most of these can be avoided, and in particular, chain reactions, which threaten flammable energy storage, can be made a non-issue.
do you have a description of the ".mov tree of structs format"
Asetniop is a terrible name. It might be very intuitive to those who know your key arrangement, but for newcomers, the name conveys nothing.
1^m3 of 300 bar air = approx. 30 kwhr.
Approximately 1/4th of that in water storage will hold the heat.

We're aiming at a daily loss of 1%, but it caps out at 10% relative (~7% absolute) because the Energy Out/Energy In is proportional to T_exp/T_comp (in an absolute scale) -- if the temperature drops to ambient, T_exp is only slightly lower in an absolute scale.

Instagram Stole My Idea of Making Instagram for the Web
My favorite part of the video is where they explain all the cool things you can do ... WITH A KEYBOARD.

Seriously, though. I've experimented with chording keyboards in the past. Conceptually they're quite cool, but their advantages are outweighed by the finickiness of having to master a new set of split-second timing issues. I can only imagine having zero tactile feedback on top of all that. (And then opting for zero visual feedback as well?)
Yelp actually does have an algorithm for computing the final star rating. It is not a simple average across all ratings. It takes contributor status on Yelp, age of review and other signals into account before the final score is published. You can, of course, dig into the rating distribution to see the spread between 1 and 5 but I doubt that most users go that far.

I've taken the same approach. Also no longer using Facebook Connect to sign up for new services - which is one of the only reasons for maintaining an account.
The aesthetics are similar to Facebook probably because they're sharing the exact same design team.
The problem with Yelp for me is that it lumps every review together, when I'm part of a niche market. I wish there were a review service that matched me with restaurants people like me (similar background, favorite restaurants, etc.) enjoy.
Besides a generic wish of a pleasant board bring up, I just wanted to pass along this message: the fear of cutting your board is only matched by the joy of seeing it come up for the first time. And even better, that's when the learning starts. Good luck!

Free with a 2-year contract. Like "Free printer with a new laptop". But yeah, the amount of the monthly service fee that goes toward paying for the "free" phone is probably more than the cost of the phone, thus a profit for the carrier.

Simple version (in pseudo-C): struct Atom { uint32 length; uchar type[4]; uchar data[length - 8]; };

I get what you're saying, but I would absolutely love a completely plain version of Google, where I didn't have to opt-out of anything ever again. Yes, sometimes it might be nice to get results that are in my neighbourhood or relevant to my interest, but sometimes I wish I could get what Google thinks is the globally most interesting response. Iterating and expanding on the query actually lets me learn about the subject.

David Braben has toyed with my heart and broken it at least a dozen times since the beginning of this millennium. I've been teased and tortured with promises of Elite 4, scouring internet forums and chat rooms for any new information. My sickness manifested through vivid dreams of piloting my Cobra MKIII, loaded with contraband, and shooting my way through a swarm of nimble police ships. Awakened, I inevitably struggled with the sudden realization that Elite 4 is not reality, and it may never be.

And now - a new hope awakens! And despite the burning scars of previous disappointments, I pledge 20 quid like a sad, pathetic junkie whose rehab never quite took hold. This time, I tell myself, this time it will be different.

People will pay a premium to get the best, but apple isn't clearly the best anymore (except in terms of apps selection, and as app devs will go where the market is, apple may lose this advantage as well).
Interesting, so how is it different from something like jQuery mobile?
Further points:

1) The specs are now much more publicly accessible than they used to be, and frankly the spec does a fairly reasonable job describing a tricky format relatively compactly. It requires a fair bit of knowledge of Photoshop to read and understand, but it’s mostly fairly explicit. Much better than many other proprietary document formats.

2) For someone with relatively extensive knowledge of photoshop, the format is fairly comprehensible, albeit complicated. The biggest part of the problem here is, as you say, that Photoshop just has a ton of features to support, so that becoming enough of a Photoshop expert to understand it all is a difficult undertaking by itself.

3) The code this comment is taken from only interacts with a small fraction of PSD features, and is frankly pretty awful code: hacky, ad-hoc, not modular at all, etc.

All that said, if someone was to redesign PSD format today, I’m sure it would be organized quite a bit differently, and would have much better re-use of a smaller number of features. (The same goes for Photoshop itself.)
The size isn't that different: if your controls are small enough that they work on the 9.7" ipad but not on the 7.9" ipad, they are probably too small.
Here you go:
http://atomicparsley.sourceforge.net/mpeg-4files.html

Nearly everything inherits from a basic struct that is 8 bytes per atom: { length of self + children, quasi-human readable 4 char code describing contents }

Practically speaking, in C/C++, you can stride by length and switch() on the ftype, using it to cast the read-in data to whatever class/struct you desire.

All of this while being so brutally dumb that you can rewrite it over and over again in about 10 lines of code in most languages.
Elite was the most enjoyable game of my youth. I was lucky enough to have a Model B and although docking was hard it was also very satisfying when you got the hang of it.

Excited to see how this iteration of Elite will turn out!

Ahhh, Christmas 1984, what a sweet sweet time.
Ha, no need to apologise! The fix works great.
Aren't the controls a bit tiny?

No. The controls are literally identical in size to the iPhone. It's the big iPad's controls that are oversized.
Nevertheless personalized recommendations doesn't avoid the issue that the parent was talking about. Say based on my personal history, Foursquare figures out that I love Pizza.
Say I am in Denver, CO tomorrow twenty feet away from two Pizza places, both of which have equal ratings but only one "real": Let us assume that both don't pay
Foursquare any money but one is a false positive due to differences in personal taste, artificial pumping of results etc. An algorithm is not going to obviate the issue of making a wrong recommendation.
I helped with this too. Lot of fun working with Node.js for the first time.
Consider a big Carnot cycle. It's 100% reversible -- as efficient as you can get. No losses. And it's 100% reversible no matter what temperature it operates at.

The Carnot cycle is:

1. Isothermal compression (T_c)
2. Adiabatic compression (T_c -> T_h)
3. Isothermal expansion (T_h)
4. Adiabatic expansion. (T_h -> T_c)

The adiabatic compression and expansion processes are just to get between the two temperatures, T_hot and T_cold.

Suppose T_hot = T_cold.

Then there's no adiabatic section, and it's just

1. Isothermal compression (T)
2. Isothermal expansion (T)

The amount of energy out/energy in is T_h/T_c = 1.

This is a 100% efficient energy storage system. It is also our idealized cycle -- a gigantic, single Carnot cycle, storing energy in heat and in low entropy, highly compressed air.

Now, the Carnot efficiency, or the efficiency of a heat engine, is a completely different kind of efficiency. It's the TOTAL energy out divided by the heat in. This is

(W_out-W_in)/Q_in

In our case, the Carnot efficiency is zero, even though the cycle is reversible, and the energy storage process is completely reversible.

Interesting, no?
