The potential deathblow for a lot of these struggling platforms is that Apple is coasting on a longer (15 month?) product cycle this year. RIM, Nokia (and Windows Phone generally)and HP's webOS platform are counting on big fall launches, but a big simultaneous iPhone launch might relegate the rest to noise. If the rumored new Nexus phone launches around the same time, it's not hard to imagine a 2 way platform race.
Previously, in a kind of reverse thing, any booklike app that didn't have interactivity was refused as a normal app and had to go in the iBook store. But interactivity ie Javascript in iBooks did not seem to be allowed.

The ePub committee spent a lot of time trying to decide if ePub was just a browser and what an eBook was, but maybe Apple have decided.

Not sure they would accept an HTML5 game as an iBook though. A kids book with puzzles in might work though and still sell as a book not an app.
Well, I only care for public Web APIs. Though if you're not writing your documents by hand, I don't see how the syntax matters (it's just library then, anyway). And if you are writing your documents by hand, there are better solutions than JSON — for example YAML (which is excellent!).

An application like this is a good candidate for review what the hell is going on, before making any decisions about changing the stack.

As a web developer who specializes in JavaScript, I'm really thrilled -- but as a person who reads books, I'm a little worried. What does the iTunes approval process for iBooks look like? Will any kind of HIG be enforced on the books? Do book publishers have good taste in interactivity? If I wanted interactivity, I would go to the internet.

Spotify, Gearing Up For U.S. Launch, Closes Its $1 Billion Round
Why is deferring execute to a button any better? A user that visits a site is implicitly trusting it; it doesn't take additional trust to click a link (or hover over a link, for that matter). Sandboxing js to only user explicit events will take us back to the browser stone ages.
I added a more detailed explanation, I hope it makes sense:

In a database with a schema, if you saved a string to an integer field, the database could either complain or coerce the string to a integer. Either way, whenever you read a row, you know what type the value will be whenever you read data a row from the database. Another issue with schemaless is simply mis-typing the key (column) name. If you have a field called referrer, but you perform a query using referer, MongoDB won’t know you have done anything wrong. In a SQL database you will get an error on insert and on querying. An ORM can instead be the one to tell you about the error.
The purveyors of ActiveX objecting to something on "security" grounds: that's almost too rich for words.
They did consult with me (@nuxnix) first to be fair to them. I was in favour of the idea because a)they told me in clear terms that they were going to run developer outreach events worldwide anyway including in London and b)I felt we had a shot at better influence and ultimately better governance from the inside. I was very positive about it to them, gave my agreement, and suggested they speak to @jot. I had to make an instant decision and I did. I stand by it.

How to Optimize Your Facebook Page for SEO
In the drinks industry an optic is the thing that goes under a bottle and measures out a serving. You see them in bars and clubs all the time but mainly on spirits. I'm guessing people don't use them on wine bottles much because you go through a wine bottle a lot faster than a spirits bottle. Or maybe it mucks up the taste. I never asked when I worked as a barman.

If you've ever seen wine served you'll see them often using a metal cylinder which often they wash out. It takes barman time and I'm guessing isn't great for the taste.

So it probably is a real problem they solved.

However I can't find the phrase you're referring to on their about us page, so not sure what the change is.

I'm doing it a little simpler and I think it's even easier to spot missed translations. Let's say there's a text that translated in english would be:
'Please type your username and do something'.
Instead of using plain english as the source for the translations, I'm using something like this as source: 'TYPE_USERNAME_DO_SOMETHING'. Caps are very easy to spot.
MIME multipart is pretty good in and of itself, and in particular can represent a larger space of content types well. I'm trying to imagine how this interacts with things like URI fragment identifiers, though. MIME has Content-ID, but that's defined to be a msg-id, which doesn't help much. xml:id might be more effective in a sense, but then you run into the internal collision problem again.

Implementationally, hooking up an extra MIME layer is a lot more cumbersome than it should be. This is theoretically a transient characteristic, but I have the creeping feeling that that will destroy any attempts to use MIME for this purpose regardless.
Because:
1) const is not supported by an optimized compiler and any function that declares or references const variable will not be optimized;
2) const is slower than var because it has a more complicated semantics;

The irony of it is that Adobe took AS2 (wich was ECMAScript) and turned it into a Javesque language. Not only javascript has blossomed, but performance was always coupled to the static nature of AS3.

In short: they moved the language to the opposite direction of where most people are going, and also ended up with a slower statically typed language.

Currently we focus on mobile apps but we plan to support the server in future.

Ok, managing a platform is not easy, I can imagine.

Me: I can't migrate my db. Import does not work.

Why Are Women Funded Less than Men? a crowdsourced conversation
"It is not the critic who counts; not the man who points out how the strong man stumbles, or where the doer of deeds could have done them better. The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood; who strives valiantly; who errs, who comes short again and again, because there is no effort without error and shortcoming; but who does actually strive to do the deeds; who knows great enthusiasms, the great devotions; who spends himself in a worthy cause; who at the best knows in the end the triumph of high achievement, and who at the worst, if he fails, at least fails while daring greatly, so that his place shall never be with those cold and timid souls who neither know victory nor defeat."

Hi Patrick - Our goal isn't to charge money to customers who already know about existing brands, but to provide first-hand information ABOUT that brand that customers wouldn't otherwise learn from other sites (including the brand itself).

We've been focused on hotels in this specific example, but the same argument could be applied to any travel destination. If you're planning a trip somewhere, would you only want to get information from the official tourist bureau and the hotels themselves, or would it also be beneficial to see candid reviews, blogs, and photos, and interact directly with other travelers who have been to the same place? I would argue that the value provided by that information is worth a lot more than 2%.

The average traveler researches 2-5 sites before booking. and a large % of them are motivated by a desire to read reviews (http://www.phocuswright.com/library/fyi/427). Clearly there is some value provided there, and if we can provide relevant and unique information that leads to a sale, or profit off the sharing of such information through unobtrusive advertisements, then I don't see any problem with that.

And if we can provide more useful information than our competition (many of those sites listed above have almost no original information at all), then I also see no problem with ranking higher in the search results.

That's not to say we are 100% there yet for every destination, but I believe we do have a ton of valuable information, and our goal is to get to 100%.
That's not really an explanation, though. It's really saying - you don't know enough (yet) for me to explain what I know, although I don't know everything.

Because they value speed and cross-browser compatibility more than conforming with the standard. As long as the errors are minor and don't affect the page display (and I am sure Google is well aware of that), you do not really need to care about valid html code.
My "simpler than I thought" moment was when I really understood javascript, after having programmed a few years with a strongly-typed language (C#, before C# 4.0 and the dynamic objects).

When I understood that everything is an object, how the scope works with inline functions and callbacks, etc... I was shocked at how easy it was to do everything in javascript with very little code and while still being easy to read and very flexible. I now embrace Node.js fully and I love every part of it.

I believe it's a combination of application and stack that's the problem. I've been comparing Rails 3 apps to similar apps in other frameworks. Locomotive is a Rails CMS and it was taking ~1 second per page load. Calypso is a CMS in Node.js and page loads were nearly instant. Both used Mongodb. Locomotive sped up when 4 unicorn workers were applied, but it still didn't match Node.js.
That's an insane ride. Bad luck is one possibility, but 6 developers... Jeez, that almost has to be something being done wrong. He does admit at one point that he wasn't doing enough to try to keep good talent.

Programmers aren't really primadonnas, but they will leave if they don't think they are being treated right or fairly. (That isn't to say they ARE being treated poorly, jst that they think they are.)

For instance, I left my last job after 2 bad raises and a vague promise that salaries would be 'fixed' sometime later in the year. I was told that if I was 'really serious' I should see my boss's boss about it. I chose the other direction. And I make a lot more money now.

To be fair, I loved my job in both companies. It was only the unfair salary policy that drove me away. Now that company is forced to try to hire someone as good as me for less than they are worth, or pay them what they could have paid me but without my 5 years of experience with their systems. It's lose-lose for them.
Lets start with a simple case: Imagine there are two parallel wires with current flowing in opposite directions. There are roughly the same number of electrons and protons in each wire but the electrons, unlike the protons, are in motion. Now, imagine you ARE an electron whizzing down one of those wires. If you look around, you'll see all the other electrons in your wire are (more or less) stationary relative to you but the protons are moving backwards at a great speed. Now, you look over to the other parallel wire. Over there, the protons are moving at the same speed and in the same direction as the protons in your wire but the electrons in the other wire appear to be moving backwards twice as fast! In any interval of time, you pass twice as many electrons as you do protons. Because opposite charges attract, this produces an attractive force that we label "magnetism."

Disclaimer: This may be utterly wrong. This is my understanding from the internet and a first-year engineering electromagnetism course.

In fairness, Adobe would do a lot better if they had the same level of compiler talent behind AS3 that V8 has. There's nothing fundamental about AS3 that makes it any harder to optimize than Javascript, and the optional static types should only help.
You probably didn't read what came before this sentence... The point is exactly that, with a good web search engine, content writers shouldn't have to do anything other than writing content in order to appear on the search results. Google is the one that should be actively looking for content and ranking it accordingly, instead of myself doing any work other than writing.

The world needs more math experts who break stereotypes, not reinforce them.

If public schools create such a stigma against nerds (driven by the violence against them?), perhaps it is the environment that needs reform. It shouldn't be up to naturally nerdy people to deny their nature (in order to survive), but for the system at least not to stifle them.

I'd say the world needs more math-knowledgeable people period, be they experts or amateurs, nerdy or not.

I think 3) is better now that version 2.0 of Mongoid has been released (and is stable). The developer I am working with complained about earlier versions also. I ported hundreds of lines of ActiveRecord model code, and it mostly just worked.

I am not really experiencing pain around 1) either. I am using factory girl and find it easy to build any required data. It could actually be beneficial that you must focus on creating a group of properly linked objects. I have run into trouble before with messed up/difficult to create object graphs in ActiveRecord tests.

2) Is a good point I am now mentioning in the post. I will let others argue with you about its severity :)

I rather like redis, once you get the hang of doing things in that way, and if you plan your system so that you know what ways you're going to access your data in advance, it's really not a problem. Besides, say you want to get a list of "events" by date, you can regenerate the index, or do the sorting within the app.

Square peaked in my interest in hardware. If Square didn't exist and I had the idea, I probably wouldn't have done it given

b) that an audio jack could transmit more than audio

That opened my interest to exploring all sorts of things about hardware where previously, my entire experience on the technical side had been primarily software.

I understood it as a question of how many strategies/antidotes are retained. Do the males specialize in only a few poisons at any one time, and so the females also specialize in a few antidotes, and new poisons are developed and old ones lost? Or do males release all developed poisons up to that point, and so the females have to manufacture all known antidotes, with no poisons being lost when new ones are developed? (Think of a modern military; they have fighter jets, yes, but they also still have the age-old weapons of knives and swords.)

I can't help thinking people who say MongoDB should be a "default" for all web apps are people who've never had to set up, maintain, monitor, debug, or fix a real MongoDB instance in production. It's a pain in the ass compared to MySQL or Postgres. Since doing it right involves redundancy, 64-bit environments and lots of storage space, it can be very expensive to host yourself, and Mongo-as-a-service options like MongoHQ are also pricey for the level of storage/performance you get. That's not to say Mongo sucks — I love Mongo, but I've been burned enough trying to use it on various projects to make sure I (or my company) have a solid reason for needing it before subjecting myself to more pain.

In my experience there are always ways to tweak something in your RDBMS setup to improve performance, like tuning queries or your indexing strategy, or skipping using an ORM for super-critical stuff, or looking at I/O latency or blocking issues between your app and DB machines.

This is true. In the long term, Russia needs to decide whether it wants to be a satellite of China, or part of NATO / the West.

Bear in mind that SCO isn't actually a military alliance (with mutual defence obligations) yet, although it may become so in the future.
