Some things to consider in all this:

In March 2011 solar module cost of production was predicted to hit 50c per watt in 2016. http://blogs.scientificamerican.com/guest-blog/2011/03/16/sm...

Solar module purchase price is now at an average of 36 cents per watt. http://www.webcitation.org/6QcjhW4C9

Oh, and much of that shale seems to be a lot less productive than was claimed. http://www.industrialinfo.com/news/abstract.jsp?newsitemID=2...

And there's those neat sounding Ryden batteries and folk like lightsail waiting in the wings. http://powerjapanplus.com/ http://www.lightsail.com/

Energy politics are going to change, and when they do it will be very fast.

If those Ryden things are anything like as promised, throw all your money at organic cotton and by extension, anything to do with cleaning lots of water. IMHO, the solar is in a race to the bottom, it is the storage that will make the real money.

There might be a world war over oil and gas, but if there is it will be through inertia more than necessity and the longer we manage to hold off, the less likely it becomes.

Politically though, keep an eye on Turkey. It is the canary in the coal mine at the moment.
> That disagreement seems to be evidence that there is a widespread expectation of privacy,

I think HN at times seriously confuses the concepts of expecting privacy and wanting privacy. Everybody says "I expect this to be private" but if you ask why, it seems the answer is "because I would like it to be private".

I think it would help to sit down and explain exactly why one would expect radio waves being broadcast into space not to be picked up by anyone with a radio. (going back to aereo, was the HN consensus not "if they're transmitting their data into space, anyone with an antenna can do anything they like with it"?)
I'm in your boat . . . I have a 4.

You don't need the entire blockchain on your phone. To answer the question:

> practically keep in sync on a battery constrained device

Simply don't, and have it be an app for blockchain.info (ie, someone else hosts the wallet and sends the money) or for your own personal wallet (that you have hosted somewhere).

But in practice, all you need to initiate a bitcoin transaction is the signing key of your address and someone to send your transaction to in the swarm. You never need the blockchain itself to do anything - if you forge illegal transactions where you say "give 50 bitcoin to X, but I only have 5" the chain will disregard it as false. You don't have to know your own balance to do that. And you don't need the blockchain to know your own balance - plenty of web services provide APIs to query the balance in a wallet.

And common retail works just fine here. The store is an entry point into the blockchain, and it is in their interest to provide a valid entry point to submit transactions through. They can't modify your transaction because they don't have your private signing key to authorize it, but if they don't broadcast it and have it confirmed in the swarm they can't get paid. It doesn't get quite as simple as "swipe a card" because you need some transistors that construct a valid transaction that requires your private signing key, thus you can't use a public terminal to generate it. But it doesn't need to be complex, have internet access, or have a complete blockchain to work.
The top 25% of apps did not take 10 employees to create them, unless there are 2.5 million iOS app developers running around.
Everything works. HIT works. Riding your bike once a week works. Walking every day works. Taking up tennis, or soccer, or frisbee works. The point is, short-duration studies on the untrained provide little to no information. It would have been much more interesting to test and compare 3-5 different exercise modalities.

One of the youtube movies on your linked page is titled "Hexiled Gameplay iOS & Android iPhone & iPad HD" and uploaded by "AndroidGameTech".
Why? I don't see sellers on Alibaba advertising the number of units that they can produce per month. Aliexpress is much more like ebay if you always filtered search with "buy it now" (except that the prices are generally lower and you have to deal with longer lead times). Amazon kills it with breadth of selection and fast delivery times; I haven't seen anything out of China that compares, but the Amazon prices are higher for comparable items.
This is a terrible, terrible idea. The mods of each subreddit are what keep the subreddit alive, and subreddits are the building blocks of Reddit. There are mods who put tons and tons of time maintaining the quality of their sub(s), and they are volunteers and don't get paid for any of their work. Asking them to "pony up" their own money would, with no doubt in my mind, drive them away and completely destroy Reddit. You are grossly over-estimating the number of mods who would "help foot the bill," and completely forgetting about how much hatred Reddit would get form the community if this was implemented.

If Reddit considered this strategy for monetization, they'd be much better off shooting off their foot, then shooting their other foot.

Oh right. Very rarely do I view the App Store in iTunes. The only legitimately useful reason I have for doing so is to quickly see rankings in a specific country's store (but doing so removes all Genius & iTunes Match data, so is pretty annoying also).

Before Google switched over to Wallet and allowed responses to reviews, you could get a fair bit of info about each sale (for a paid app), including often their email address.

I would often email people seeking clarification when they would review "XYZ doesn't work for me" in a bid to fix it.

On one hand it might seem a bit creepy, but on the other hand, they were my customer and I was provided with information about them. I never asked for a better review, just for information to improve the product.

They rarely replied.
Based on the discussion in Kyllo v the United States ( http://en.m.wikipedia.org/wiki/Kyllo_v._United_States ), (1) the justices appear to ask "is this sportsmanlike behavior?" when deciding whether a warrant is needed, and (2) the official line is "does the general public believe the police have the power in question?"

It seems to me that this currently would be struck down under Kyllo, but that if the police make a big deal about their new tool, they could eventually use it without a warrant.

It's almost like you didn't read my comment at all.
Consider removing the downvotes? Keep only the upvotes?

Downvoting IMO feels bad for the poster. They stop feeling like participating. They might have very good and insightful posts which might not be popular. The downvotes end up driving them away and all you're left with is an echo chamber of groupthink
But the HN team is no different from a set of good subreddit admins. As an example of a bigger "good" one, askhistorians is insanely stringent on deleting posts from non-experts. You get insanely detailed recollections of historical events, its lovely to read most of the time.

A subreddit is as good as its moderators are at managing it. In almost all ways, HN is just one of the subreddits I frequent.
As a long time reddit user my question is: is there something specific pushing for further monetization? I thought the whole purpose of spinning off from conde nast was to get away from the need to monetize.

Why not just match development/maintenance with use? Reddit is well past it's exponential growth phase and is big enough to sustain the community with basically no growth in userbase - so unless I am missing something, this seems like a pure greed play.
It's a fair point, but if the prices were reasonable, i think the firms would see it as a cost of doing business.

Remember this is revenue from firms attempting to create content, not paying for ad space. You'd have a shallower river of income, but a much wider one.

I'm not saying it would definitely work, but i think it'd certainly be something worth paying for. Especially when you're watching your ad successfully drive lots of users to your product... it's working! And then suddenly reddit calls your firm up and says:

"Hey, nice successful ad you have there blowing up on our service. It'd be a shame if anything were to happen to it..."

As for the users, if you shadow ban the content, more often then not they wouldn't even know. If they find out, you could simply explain that the relevant firm is abusing the service. Most would even help... a small button (is this an ad?). I'd click it, because i would know clicking it helps reddit. Remember, redditors are adults, with brains (they watch community, not two and a half men). There may be some push back, but i know i'd certainly understand, because big firms cheating the system is bullshit, especially if price discrimination is put in place to protect small firms. Dollar Shave Club pays pennies, Gillette pays hundreds.

And, hey, i really do love the site. If Alexis or Steve are ever in need of a beer in SF, i'd be happy to buy it.

I know the comment i'm about to make actually follows the rule you just outlined - but it's really about which subreddits you're subscribed to. The general advice I give when introducing someone to the site is to ditch most of the default subreddits and pick ones that relate to things they're already interested in. Small subreddits have really great communities and are still generating useful and interesting conversations.
Just guessing what he meant:

The black cars in NYC with an iPhone on the dashboard running the Uber app aren't necessarily getting 100% of their fairs via Uber. If they see you as a potential client, they'll still try to pick you up off-network.

If you already hailed an Uber, an unscrupulous driver may potentially tell you "Yeah, I'm from Uber". Although I'm not sure how they'd convince you to pay cash.
>Equal value, of course.

Both people in a transaction value the thing they have less than the thing the other person is offering, otherwise there's no reason to bother making the transaction.

At least, in theory.

IRS Reports New Round of Computer Crashes
bcbrown covered this pretty well in their response to your comment, but I just wanted to reinforce: it's well established that doing almost anything will show improvements for untrained people. So this study, like most studies, doesn't really tell us anything. On the other hand, many people start exercising, feel great for a few weeks, and then start to not feel so great, and stop seeing improvements. This is the point where we need to start focusing research. There is good anecdotal evidence for what to do next, but it needs to be backed up by studies.

Also, you can hardly claim to know anything quantitatively when your sample size is 14.
bar none this is my favorite genetic algorithm story. Not because of how it 'failed' but in the fascinatingly unexpected way it succeeded. This type of solution is one you would likely NEVER see come from classically trained EEs. That's where I see much of the value in GA/EA, finding solutions that no sane engineer in their right mind would ever come up with.
Even after reading this, TTYs will surprise you. I've done my share of TTY programming in Linux and here be dragons.

From modes to tty types to control chars and signals, the TTY system is itself a bloated relic whose stink becomes apparent when you try to connect it to the rest of the unix philosophy, where everything is supposed to be a stateless text stream.

This stuff is really interesting for historical reasons and made sense 20 years ago, but I long for the day where the TTY system is gone and character drivers work on some standard JSON stream or something.
Perhaps you didn't understand the article then, which is tracking battery capacity. Above comment was noting that its possible after a couple years a MBA (with its non-user replaceable battery) wont hold much charge compared to new, which means Apple will need to service it if you want to maintain battery life. I think its a legitimate problem, and a good reason why my latest laptop has a replaceable battery.
This was a great read, I hope it stays on the front page until morning so more people see it. It filled some gaps left from my Operating Systems class about TTY, especially the history with Teletypes.

I am wondering what most of those game developers use for writing apps. Your app looks pretty minimalistic, and I do think it could use at least some additional decoration.

But writing my own game apps, I do realize why you're not doing that when implementing games directly in things like SpriteKit.

Are they using flash ? Unity ?
SA has also charged for registration for the vast majority of its existence (it was created in 1999 and started charging in 2001), so if it was supposed to be a cash-out before the site died it was a very poorly timed one.
Which size of MacBook Pro are you using? I am considering 13" because of its lighter weight (compare to 15").
The site now says that the mobile site is unavailable. Perhaps they've taken it down to fix this? I'm in Australia, so maybe that's it.
> in the old SOAP days

What I thought was strange is that we're not in the 'old SOAP days' any more.

I get what they wanted to do - speed things up by including common data in every request, and avoid state in apps. What I found strange was the way they solved it, esp. given they're (apparently) using Python and Node.js - writing a middleware to insert the common data would be far easier than implementing their own routing layer or whatever they've done.

Of course I'm making a lot of assumptions about what kind of stack exactly they're using (assuming they're using a web framework that we've heard of)
I feel like the idea of "default" subreddits that everyone is subscribed already when they create an account is part of this problem. If they instead polled new users on their interests/hobbies and generated a list of related subs based on your choices it would be a huge improvement, and could be used to gather data for advertisement.
Since they simply asked restaurant owners, there is a "soft" attribution to the legislation: "in the owner opinion..."
There is a specific field on the App Store listing that says:

"Language: English"

I don't think it's a valid complaint, but it's a complaint nonetheless, and their complaint holds as much weight as someone complaining for something such as an app crashing. So we can only do what we can do, which is either add more languages, or tell them multiple times.
I don't think this press release has nearly enough buzzwords.
No reason to hide it until it becomes a problem. I suspect now that someone's gone to the trouble to surface it, they'll patch it out, but really, it doesn't matter if a tiny percentage of uber-users know what their score is.

It's an optimization for their developers. They probably don't want to write a bunch of "if user.driver?"'s in their API responses, so just return all the data all the time and let their clients decide what to show.
As an artist, and armchair historian I would LOVE to hear more. I don't require cheque out sources even, I just want to hear more. Mesopotamian history is my favorite period.

“The important fact is that this man’s DNA is the same as

practically nonexistent.

This fundamental misunderstanding of statistics really doesn't increase confidence in this investigation. When you go on a fishing expedition across 22,000 suspects, the odds of getting a false positive from one cause or another is nearly one.
Man, I remember back when /b/ was good.
On my browser, the rating is at

window.Uber.Ping.Client.attributes.rating
But as I say in the GP, I am assuming that the drivers don't know that they are given a low rating prior to giving the passenger a rating.
Errr.. relevant?
Lol. I always give them 5 too, and tip them additional cash even, and I have a 4.8. Jeezz though crowd. ;-)
I'm at 6 years on reddit and I don't think I have a single one of the defaults still subscribed. In fact, I've probably added and removed enough subs to probably be on a complete version 3 or 4 of my subscription list. I have collections of subs that range from some common to some very niche interests and I can almost always find something high quality on any given day.

You're right, you have to be brutal about your subscription maintenance. Once you stop liking a sub, unsubscribe immediately. Can't find a sub you like? Make your own.
Good point. I don't know that the lungs are technically muscles (probably they aren't...I'm not going to cheat and look it up until later).

But for this purpose they behave enough like muscles... i.e., they seem to grow stronger. Or maybe it is indeed muscles like the diagram being strengthened. Perhaps someone with a bit more actual physiology knowledge can answer.

Edit: Also, I forgot to mention, I do this twice a week and sometimes thrice a week, with off periods of a few months every 5-6 months or so. I've been doing HIIT in periods for 3-4 years since I first read about and I'm a believer. Big change.
Ow thanks :-) The reason I used progress-bar is to show the busy time of the browser while performing the action.
Chef is being used to build the VM and put the entire thing together. But after it's built - you never need to use Chef again.

Fig didn't exist when I started this and I wanted to mirror the git push that Heroku used.

Logging is handled by Docker - and can be sent to services like Papertrail if you use something like logspout:

I am a web developer/designer and certainly not a game designer or illustrator so I guess in tackling a word game, we avoided 3D models or other things we couldn't do ourselves. We abandoned our initial game concept because it was going to require more challenging artwork.

The music was something we used a freelancer for, however.

Hopefully if Hexiled continues to prove successful, we're in a position to get help on the visual side!
That is weird. As these things go, I'm reasonably high profile. I'm also connected to some vertices of extremely high degree. I get zero fake friend requests per week.

octohost is like a mini personal Heroku.

Packer is a tool that helps to build the image that octohost runs on. It installs all of the software needed and prepares the VM it runs on.

Vagrant is a tool that allows you to run different virtual machines on your local development box. It has nothing to do with production at the moment - it's just for running it locally.

The octovagrant box is pretty open - but that's because it's for running things locally. When it's installed on AWS/DO/Rackspace/Linode/etc. it's firewalled from remote people - but still is pretty open internally. I wouldn't let untrusted people push to it at the moment.

Yes - you need all of the cookbooks, but Packer will take care of that for you - you don't have to really worry about that.

If you're just using the AWS AMI that we've already built - then you can really ignore Packer and Chef - just launch the AMI and you're done.

Docker allows you to run processes inside of a container. So you can launch a set of processes from your source code and have it run on its own.

Once it's setup, you merely add a remote git target, push your code to the server and it builds and launches the code that you have pushed. It works like Heroku for simple websites.

That help at all?
How did you iterate on the game mechanics in the early stages of development? Was the original version of the game significantly different from the final released product?
To show the difference between performing a time/resource consuming action on web browsers with web workers and without it.

Excuse me if you didn't find it useful.
I think Unity is pretty common. There's tools for converting cocos2d code to Android, so that one too.

Being the first game I've ever made I wanted something I could jump into really quickly just to play around. Got a bit of momentum on it and kept going.

I do wonder about the future of SpriteKit because of this, since having to code it two or more times is a huge effort. Apple seem to be all-in on it though, especially with SceneKit coming soon.

There are a ton of cross-platform frameworks, both proprietary and OS. Here are a few of the bigger ones: Marmalade, Cocos2d-x, LibGDX, Xamarin, and Unity (you can 2d with Unity now, I believe).
Low ratings are not the only reason that could happen. Uber drivers run businesses. They are not universal service taxis (which often flout the universal service rule, to be true).

Your request for service includes several non-price elements to it, one of which is your perceived likelihood to be a hassle (and reflected in your star rating), one is the amount of unpaid travel required to get to you, and one is what the driver perceives as likely to be your destination. All else being equal, drivers would prefer to end up in portions of the city with a high density of quality fares (say, an airport, the startup district(s) in SF, etc) as opposed to portions of the city with a low density of quality fares (say, the outer edge of the service area).

If drivers make a habit out of taking "bad" trips, their Uber business gets meaningfully less lucrative. Accordingly, expect them to actively avoid "bad" trips. If one's travel patterns routinely result in drivers perceiving you to require "bad" trips, one is going to have a far different experience with Uber relative to a high-frequency no-hassle business traveler.
I can't find it either. I think I could reword this general topic to: "A lot more people from non-English first language countries are using our game, holy crap, we need more languages" ;)
