40% higher is not a very big number either when you consider how low the visitor count is at this point. And time on site could be an important metric, but really it depends why time on site is higher and how that fits into their revenue model or engagement over time (repeat visitors, etc.).
Why all the hype about Twitter Music app? I just don't get it. Can someone please explain?

Ready to Go WordPress Websites
A lot of providers already but I'm still looking for some suggestions :
This would be a new service and an awesome kickstarter for websites. I'm sure, a lot of startups and entrepreneurs would need this.

The flow is easy and the final product is a ready to go WordPress website.
1. Select a domain name
2. Select a WordPress theme - (Selected awesome themes directory + option to choose from a marketplace that has around 6000 themes)
3. Your website goes live in 5 hours and you can start adding content as soon as the DNS resolves.

This isn't another Basekit implementation or a website builder like BigRock, GoDaddy, Free Website Builder | Create a Free Website | WIX etc.
These will be awesome and full-fledged WordPress based websites.

This isn't a new idea but an implementation. What do you guys think of it? Viability? How much should it cost?
In some browsers, removing the ability to zoom removes the 300ms delay that the click event has before it fires.

You can use 'touchend,' but in certain cases this causes another set of bugs because the click event follows anyway.

To fix this in a cross-browser way, you need to write some extra logic. There are several implementations floating around of various quality.
Your product looks quite good, though I can't say I'm too keen on the name! If you're not already, I'd suggest aggressively reaching out to any educational establishment that might have an interest to solicit feedback and sell your product.

Speak directly to lecturers and provide them with unique discount codes to offer their students. Maybe setup an affiliate system? Give people a reason to sell your product for you.

At any rate, good luck - I can see a lot of effort went into building this.

I have a number of friends who are middle and high school math teachers. I have asked them to demonstrate this for their students and report back on how utterly blown their students' minds are.

Basically what the domain name suggests; free cam girls.

The idea is simple: you can watch girls on cam for free. But to talk to them you have to buy tokens, you tip girls you like and so on. So it's essentially modeled a bit like a strip club but on a much grander scale.
You see? When you put it that way it sounds stupid; otherwise it has beautiful words like "butchering" that convey additional feelings about the subject :)
Nomenclature is important. As the joke says, naming things is one of the only two difficult problems in computing. [1]

A good password is a long string of random characters, and an API key is a long string of random characters, but they are not the same because the semantics are different. Passwords are typically chosen by customers, changed (let's be honest) very rarely and on a haphazard schedule, often reused across a bunch of different systems no matter how frantically we wave our hands, and (most important of all) have "user" semantics and scope: a password lets a user log in and do logged-in-user stuff.

Whereas an API key can be issued by the system, and is thereby guaranteed (assuming a clueful programmer) to be long and random and unique and not shared with the customer's Gmail account and bank account. You can expire it often. You can issue more than one per customer. (With passwords, this is theoretically possible but practically impossible; customers barely understand how to handle one password.) You can issue it to entities that aren't themselves customers, and that don't have "user" semantics. You can scope it to particular uses, issuing a key that is only good for checking balances but not for initiating transactions, for example.

Neither. It's not a currency because you can't use it to buy products and services (other than drugs and socks). It's not a commodity because it's not a raw material or agricultural product.
All good questions. I'll try to help - ADVERTISERS would likely desire that functionality, but we don't plan to monetize that way.. ancillary to qualifying humans for knowledge we also gain the ability to show the most relevant articles per subject (a timeless piece on Startup financing by Fred Wilson in "Venture Capital Models" or a post on Startups from Paul Graham in "bootstrapping"). All older posts that largely get covered up in the world of 'real time' that we have become so accustomed to in this age of twitter and google. Thus advertisers could... target by keyword/s in subjects/topics (like google ads). Credits per se aren't a currency for trade. They can only be acquired through reading/learning.

I get the feeling that most people commenting here haven't actually implemented an API that is under heavy use and has strict security requirements.

One of the main problems with Basic Auth that the author fails to mention is that if your passing passwords with every request, you're also hashing that password with EVERY request (assuming your doing REST, ie no client state on the server). And if you're properly hashing passwords in your DB, you should be using a slow hash like bcrypt. That means a single request that might take 30ms now takes perhaps 500ms. And many workloads are going to require multiple hits to the API to accomplish simple tasks, so your talking about both a strain on the system, and a horrible experience from the client's perspective.

The ability to steal all of them would imply they were all in one place or a small number of places to be stolen, modulo true protocol hacks. That seems unlikely. As they get subdivided, they spread finer and finer on a per-coin basis. It would be no different than trying to steal the entire set of BitCoins today. If you think that can be done, go for it.
From the blog post:

"You can download Twitter #music from the App Store today, or enjoy the web version, which will be rolling out over the next few hours: music.twitter.com."

So the web component will be rolling out later today. The app is available and working.

"Fogcreek [sic] haven't always stuck to their word on how they will keep their systems up and running".

What do you mean by this? It sounds like you are suggesting that "how" we keep our systems up and running is required to be the same at all times. Why should people care about "how" we do it, just that it's done? For awhile, we had a second data center in Toronto instead of LA. Trello moved to AWS, so it doesn't need a 'second' data center. I don't think we should be derided because we changed the way we keep our systems up and running.

Also, minor point, it's Fog Creek, not Fogcreek.
it's not online only either, I had university classes with a guy whose family name sounds like a swear word, and since to attend exams you had to preregister on a big dead-tree book left alone, usually teachers assumed it was a joke and didn't account for him.

No, there's no reason to go looking for conspiracies. Nor do I think their intent was malicious. I think they genuinely believed that this was beneficial. We should support them if they change their presentation from "we can't access your data" to "we're not evil, so if you trust that, then use us." We should let their actions speak for themselves.
You can trade sexual favors for all kinds of stuff, but it doesn't make it currency.
You don't need a beefy network connection to run a useful Tor non-exit relay, either. As long as you have a machine that's on 24/7, and can spare at least 20KB/sec in both directions, running a Tor relay is just a nice and charitable thing to do, with zero risk.

This proves to me that Bitcoin definitely could become a useful currency, but for this to happen it will have to become more stable. Until that happens, it will remain a highly speculative commodity with a neverending cycle of bubble and crash.
Total dollar M0 is about $1 trillion (as of 2009), so if Bitcoin were to match it then 5% would be a Bill Gates-level fortune.

MO seems the appropriate measure since it's the hard currency, without the multipliers of fractional reserve. M2 is around $10 trillion.
Bitcoin is such a mix of different things that it doesn't easily fit into any of our existing boxes.

Which doesn't necessarily make it a bad thing. It just means that saying "Does it satisfy criteria X" doesn't help unless you're deliberately talking in metaphor.

In one way, it's like asking "Is the internet a series of tubes, or a superhighway?"
True, although measuring industries by environmental impact is just as valid as using, say, revenue or profit or number of people employed.
Neither, it is just an experiment by cryptoanarchists to see if currency without any authority is even possible.
A study I found incredible was The Harvard study on the external costs of coal: http://cleantechnica.com/2011/02/17/cost-of-coal-500-billion.... Half a trillion in external costs in the U.S. alone.

An environmental group our law school worked with (ELPC) lobbied hard to get two coal in the middle of Chicagoland (Fisk and Crawford) shut down. They did a study estimating the negative externalitiesmofnthe two century old plants at $127 million, the majority of which fell on working class people in the areas around the plants.

A related phenomenon I found interesting is an LSE paper (can't find the link offhand) arguing that the GDP calculation vastly overstated the GDP of countries built on resource extraction. Income is change in wealth, but when $100 of coal is sold, it is counted as $100 to GDP. But the bulk of that price is offset by the decreased value of coal reserves in the ground, which isn't counted in GDP even though its part of the change in wealth.
Another one bites the dust. The app my team and I have been developing is an HTML5/Native hybrid app, much like LinkedIn's was, and their decision to move away from their HTML5 strategy is a bit baffling to me given how well things have worked out for us.

Our app has a few native ui elements like the top bar, the bottom tabs bar, a quick add control that slides in and out, and Facebook style drawers that expose two other webviews. The rest, however, is done in pure HTML/JS/CSS. Angular.js, in fact.

It runs well on old android devices with 2.2 installed, and runs really well on newer Androids and iOS devices. We take full advantage of the benefits HTML5 provides. Most of the user's important data is cached in localStorage so the app loads very quickly. We use websockets to update the app in realtime without the need to rely on long-polling or native push notifications (which we do still have). We have one stylesheet with zero platform specific hacks thanks to the fact that Android and iOS devices use webkit browsers. And laying out our app's interface in CSS/HTML is much more efficient than doing it twice either programmatically or using nib/xml layouts.

We even use http://www.tidesdk.org for desktop native apps and of course that version runs fantastically. We didn't start out using Angular.js on our main web app, but we are slowly starting to transition our mobile app codebase over to our main web app codebase. At some point we will have the largely the same code running across all major offerings of our product.

Every time one of these splashy articles about a well known company moving away from HTML5 comes out I smile knowing that the FUD it will inevitably create will allow those of us who are benefiting immensely from using HTML5 for mobile to continue to enjoy our productivity advantage.

For those who are curious, our product is http://kona.com and the mobile apps are both available in the store. I'd be interested to hear any feedback about how well the apps perform (my email address is in my profile).
You could have issues with other people not running the same version of python, also you might have different site packages if you are working on an experimental branch that will be pushed or merged later.
Conformism Vs. Anticonformism
This is tangential to the pinch-to-zoom discussion, but I'd say if you have a fixed element anywhere, you don't have a mobile-optmised webapp. There are plenty of Android devices with 640x480 or 320x240 out there; a fixed header in one of them looks like a big waste of screen space.
Vitria provides continuous real-time visibility in big data
I've implemented OAuth client-side a few times in a few languages. The signing process itself may not be that difficult to understand, but there are a lot of fiddly moving pieces, the specs are painful to read, and everyone has their own unique take on the spec.

I wouldn't call it simple. It's complex to get right, and outright damaging to non-web clients except in the case where xAuth or similar is available.
What The Princess Bride Can Teach Independent Consultants
Yes, Basic auth is the default in curl, if you provide credentials off the bat. Use --digest to default to digest auth.

If you don't provide credentials, curl will prompt you and do the authentication the server requests (if any). Using --anyauth will also let the server decide.

They're probably not going to change that default and break millions of scripts on the next apt-get upgrade.
The difference is that the benefits of electricity are generally priced in, either through taxes (for public lights and whatnot) or through utility bills.

Here is an illustration. Would you rather live next to a coal plant or a solar farm? Would you rather get electricity from a coal plant at 2 dollars, or a solar plant at 3? Note how in the first case, the price of electricity is irrelevant because the external effect of the plant on you is the same no matter the price of electiricty. You can't decrease it by using less. In the second case, price is the only relevant consideration. The coal electricity doesn't have any positive benefit to you not accounted for in the price.

"cheap" by definition can't be a positive externality because the definition of externality is costs and benefits not accounted for in price.

Design by contract is great, but if you want to go beyond the basics, you really need some form of language support. In the absence of inheritance, precondition and postcondition handling aren't too tough to deal with via preprocessors. But inheritance is much harder to handle, as are class and loop invariants, yet these are the very places where DBC really starts to shine.
The way it combines functional programming with object oriented programming. This kinda gives you the best of both worlds (others may refer to it as 'frankensteinian' though).

What coverage? This submission itself seems to be the only time the site has been mentioned on HN.
I'm the developer of the pressureNET app and CEO of Cumulonimbus. We're looking to dramatically increase our measurements per hour (12,000 right now globally, need to get to 100,000 and then 1,000,000 by summertime). Building the pressureNET SDK is our focus right now as it will allow other app developers to include pressureNET in their apps, thus helping us grow quickly. There's also a data access API (which is what the scientists are using) if you're interested. Last month I left my job to build this full time. I have only some savings left - so we're looking for funding. We just got the YC rejection email, but there's a lot of other opportunities out there so I'm quite confident we'll find something.

The most excited part about this right now is the Galaxy S4 coming out in a couple of weeks: It has a barometer, hydrometer and thermometer so we'll be collecting all sorts of new sensor data as well. All of our work is open source on GitHub if you'd like to help out!

If Bitcoin's only utility is its ability to be transferred from one person to another, it is not a commodity.
This is the part a lot of people just don't understand. There are lots of people complaining "When am I going to get my money back!". But they're missing the truth. There is no money. Full Tilt spent it, faked it, never had much of it. It's like the settlement for the Bernie Madoff scheme. You can't claim the peak balance on the fraudulent statement because that money never existed.

It shows that Expert Beginner syndrome (http://www.daedtech.com/how-developers-stop-learning-rise-of... ) and associated Dunning-Kruger effects isn't peculiar to software development, but is a general part of human nature and flourishes wherever it is allowed to.
Oh yes, in source & commits it's fair game! I'm talking more about editorial content that might have been outsourced. E.g. how-to articles for a company product or articles written in-house that are localised by an external vendor. These things need to be quite clean!

I totally agree, but even just the basics can be a great addition. What I find odd is even just simple things such as pre or post conditions don't appear to be used widely, let alone cool features built into languages such as Eiffel or D.

>coal is the enemy of the human race

What a spoiled, Western-centric, historically ignorant point of view. Without coal mining in England, there would have been no steam engine, no railways, and no modern economy. Preaching to the Chinese about the evilness of coal is a classic case of pulling up the ladder after you've climbed on it.
Right now I would say it is a commodity. I think the majority of people getting into bitcoin right now are doing it either for emotional reasons or because they have enough disposable income to play with it. I don't think I could convince my mom or dad to start using bitcoin, or even just a stranger on the street. It's still just a novelty for nerds.
That's not quite right.

The case I'm tempted to make is that Bitcoin is a commodity useful for secure, private/anonymous interactions. It's virtual sure, but the utility of a bitcoin is clear to its users and it is also inherent to its structure.

I had to work on implementing fairly well-known advertiser's banned-words list into our system recently. Their system is incredibly stupid. For example, they'll ban the word "Dimethltryptamine", but "Dimethyltryptamine" (the correct spelling) is allowed. You're not allowed to use the word "bulldog" under the Pets category. You can't use the word "dragon" under Jobs. It seems like they just have a form that visitors to the site can use to link ads containing "offensive" words and the system will automatically add it to a list.
