Nice article.

While I have high respect for the exposition in this article, and by extension Mr. Vogels work that the author makes a reference to, I think it's a tad too early declare eventual consistency a clear winner. In fact, I think it's too early to declare that a there is a contest in the first place. While there seems to be some level of agreement that partition tolerance is required for real world systems consistency vs. availability is more of a continuum instead of two discrete choices. I find that in day to day work some data requires a paxos level of consistency (say a configuration file containing your inter-cluster topology) and some data can be highly inconsistent (like activity data such as 'read' status of emails).

As a side-note, I would argue that all eventual consistent systems rely on some domain knowledge about the data that makes it possible for the system to reliably merge conflicting data. Such algorithms usually have the property that they only move state in one direction, emails only move from unread to read for example.

What I'm trying hard to figure out is how Consistent, Available and Partition Tolerance map onto Intelligence, Emotional Stability and Good Looks. Do we always require Good Looks and thus end up choosing between Intelligence and Emotional Stability or ...

Maybe it's fine to duplicate existing functionality on the iPhone if you do it so badly that there's no danger of anyone actually using it.
People should only note how many people live in the dwelling and send it back. That's the only constitutionally approved question the census is supposed to ask.

The rest of the questions are there to tell politicians what group they should pander to and how to reconfigure congressional zones.

The census TV ads about filling in your race (actually your country of ancestry) are really pissing me off too. It wasn't that long ago census data was used to roundup Japanese citizens during WWII...they claimed it was private back then too.

This is pure speculation but maybe Google uses VP8 in order to negiotiate a better licensing fee once h.264 isn't free anymore. MPEG-LA would think twice about loosing Youtube as a customer. This would go against Google's "Don't be evil" but getting the world to accept yet another video codec will be an uphill struggle, even for Google.

They're undoubtedly changing the language in the developer TOS, that is of course undisputable. =)

However, when introducing the iPhone SDK, they clearly said (about XCode) "This is where you'll be developing all your apps." I'm saying you could consider this a change in legal language to more clearly adhere to the spirit of the premises of that SDK.

The fact that people have been able to use products in a grey area to sidestep this, doesn't mean that the rules have been changed, just that they haven't been enforced before. Apple never said: You can develop in any IDE you want for the iPhone, and then changed their mind again. None of these tools that are affected have been approved as developer tools by Apple before, and people using them know or should have known that.

What has happened is that Apple is starting to clearly stress that Xcode is the only approved developer tool. The major change is that unapproved tools now clearly are marked as unapproved, which in itself isn't a change from before. They've always been unapproved.

Now, as far as enforcement, that might be just the same as before, since we haven't seen any rejections based on the new policy. Most people, including me, seems to be guessing on that this will mean some kind of enforcement as well, but we're just going to have to see what's going on there. Either way, if you've been using Apple approved development tools before this change, nothing has changed, and therefore there is nothing more to worry about after than before this change in stance.
How can I get a job doing that?

out of my friends (who develop for the iPhone)? One or two.

Most are still staying onboard (maybe... 25 or so).

Don't forget this is the internet; like most things the disgruntled developers will be the most vocal. That doesn't necessarily make them a majority - or even a large minority.
Its not exactly abandoned. We will soon start posting new content there. Been completely flat out with projects for last 6 months and were short on time.
In these matters, the human concepts of size and space breaks down and are as good as meaningless, so it's counterproductive to think of other universes as smaller or bigger. They just are. :)

They did start this checking relatively late in the game however, and I seem to remember it giving rise to a number of outraged developer stories on the web.
Well, the tablet arena is becoming quickly interesting. In a year or so I hope there will be several serious iPad competitors, only quite better (fully-enabled linux OS, open connectivity, not forcing users to use some centralized online store, etc). Fingers crossed here.
Nice market segmentation :) As for Superfeedr, we already have a pretty big chunk of the blogsphere and as long as you know what you want (feeds), we can provide that to you. Other services that you mention suffer from spam, because they have a "extensive" approach. In our case, we'd rather let our users decide what they want, rather than filter for them.
Aha, so this is what an iPad developer does.

This might be far fetched, but I think we could apply similar technology to cloud computing and infrastructure management.

Especially if you watch towards the end, a robot could be instructed with a high level objective. In tandem, multiple robots work together to achieve that object.

Anyways, I have been thinking about how server infrastructure could be more autonomous and self-sufficient/self-healing.

We've known about this for a long time: just ask any weight lifter. A routine of high weight compound movements would help pretty much anyone, regardless of whether you're trying to lose weight, gain it, convert fat to muscle, whatever. Just exercise 3 times a week and eat more or less than your calorie needs according to what you're trying to do.

Starting Strength is a good program to look into, but really anything with squats, deadlifts, presses, etc. would be fine.
these guys wrote a book to that effect and then realized that for some people light weights work better:

Are you sure about the "constitutionally approved" quip? I watched Gary Locke on The Daily Show on March 18th, and he clears up a bunch of these misconceptions and privacy concerns. Specifically, he says that Jefferson was the head of the first census committee, and half of the questions even in 2010 census are questions put in by Madison.

I also don't understand why it's fashionable to distrust the census. It happens in most countries and they ask more or less the same questions. We all care about the economic and racial demographics of places where we live and work; where do you think that information comes from?

> In these matters, the human concepts of size and space breaks down and are as good as meaningless, so it's counterproductive to think of other universes as smaller or bigger. They just are. :)

But what if it is the best way of describing it? How else could you explain it in the event we discover that we can keep on finding smaller and smaller particles?

> The many worlds theory and its parallel universes is unrelated to this, so its rule of no interaction does no apply.

Yea, but I like to think of all these universes as still part of our universe, since we would be able to interact with them.
You pay per encoder and per decoder, both of which would adversely affect Google with their encoding farms and popular browser if the charge wasn't capped at around $5 million (I think it's gone up to just under 6 million this year) to stop the big players doing something silly like getting together and developing their own royalty-free codec.

Unfortunately for that cunning plan, Google clearly sees more benefit from a codec that's compatible with the open web and open source than they do from licence discounts.

It's one of the hottest stories we've ever seen on HN and I tend to see 'quantity of stories on X' as one indicator of where X will be going in the near future. Simply scanning through the HN headlines without reading every individual post has value for me.

Is this not a Turtles all the way down theory. We are in a Black hole which is inside a Black Hole?

A well-known scientist (some say it was Bertrand Russell) once gave a public lecture on astronomy. He described how the earth orbits around the sun and how the sun, in turn, orbits around the center of a vast collection of stars called our galaxy. At the end of the lecture, a little old lady at the back of the room got up and said: "What you have told us is rubbish. The world is really a flat plate supported on the back of a giant tortoise." The scientist gave a superior smile before replying, "What is the tortoise standing on?" "You're very clever, young man, very clever", said the old lady. "But it's turtles all the way down!"

At my previous job, I had a yearly performance review. It was that time of the year where my boss told me that he's glad to have me around, but that I should try to keep the procastrination under control. I really liked that. A serious, but amicable conversation, valuable in spite of the red tape.

I like a somewhat formal statement on whether people think I'm doing a good/bad job. It's also ammo when you're asking for a raise.

It's certainly not suitable to the startup model, but that's not what this article is about.
To be honest it's getting away from flash which makes this exciting for me. Wrapping VP8 in Flash would be the equivalent of putting granite wheels on a Ferrari.
I don't think there is anything inherently wrong with a Turtles all the way down theory, as long as it is supported by facts.
Exactly. I haven't had any at my current job and I dislike that... a performance review is the ideal time to ask for a raise.
If Apple wanted Unity3D to be unaffected by this change, why didn't they word their license in a way that makes it clear that Unity3D would be unaffected? Right now, going purely by the letter of the license, there is no way Unity3D is allowed. If Apple starts to selectively not enforces their license for favoured developers (as you imply and I suspect they will) then that will create even more uncertainty in the developer community.
Infosys Fourth Quarter Results Shows Recovery Disappoints Investors
I feel that it is indeed going to be a revolution of sorts, and people who don't use computers professionally will start using tablets in their work. Tablets have the opportunity to become much more pervasive: laptops by design require folks to sit down, but tablets have a nicer form factor that could replace virtually anything people use while standing up/on the move: writing pads, file folders, electrical/electronic measurement equipment(with Apple approved connectors, of course), etc. Lots of professions could benefit from a usable tablet design --- doctors, field engineers, etc.

The show Stargate Atlantis shows an amusing example of one "future". Stuck in a dead spaceship on the bottom of the ocean with air running out and water leaking in? Not to worry, just hook up your tablet to the system and hack it. For Rodney Mckay, difficult takes a few seconds. Impossible -- a few minutes.
The Constitution (Article 1 Section 2) specifically gives the House of Representatives power to decide the questions present in the census: "[I]n such Manner as [the House] shall by Law direct."

Here are the questions asked in the first census, conducted in 1790:

* Name of the head of each household.

* How many free white males age 16 and older.

* How many free white males under age 16.

* How many free white females.

* How many of all other free persons.

* How many slaves.

I don't suppose you're a fan of Michelle Bachmann's, are you? Here's a recent response a FOX News(!) anchor gave Bachmann regarding this:

“We’ve had a lot of good years since then,” Kelly said. “That was a different time and a different era. We’ve had decades since then when, at least to our knowledge, this information hasn’t been abused. So how do you respond to people who say, ‘Look, we’ve been doing it for decades since then. The law is what it is and you as a lawmaker should know better than to break it.’”

No, it would be like if you wanted to put really nice wheels (VP8) on your Ferrari (Chrome) but those wheels won't take you far if the roads haven't been upgraded (widespread usage of VP8 on websites). So you upgrade the tires of all of the crappy cars (IE6,7,8 and probably 9) for free and without them having to do anything (Flash auto-update to VP8) and then people start upgrading the roads (websites using VP8). Most people have still got crappy cars, so they might not notice any improvement but it makes a big difference to everyone else trying to make better cars and roads (the open web).

Giving up on the car metaphor, it's Flash support for H.264 that makes it viable for 85% of the market. Adobe can win it for VP8 if they want to, but I think Google can do it with out them too, it'll just take longer.

I'm wondering about their seemingly dumb approach. In my opinion it would be better to charge on per click basis for the links in the tweets. Say if want your links to be clickable you route them through a specific shortener and then Twitter counts the clicks. Others will have their links as text. Seems pretty fair to me.
I must add that, the stuffs shown in these slides are just our "level 1 scripting". There will be level 2 and level 3, so as to support more sophisticated business logic in our data platform.

Level 2 will be ngx_lua scripting which provides Erlang-style transparent non-blocking I/O support and access to the whole nginx infrastructure and all the level 1 scripting goodies.

Level 3 will be...well...Perl 6, JavaScript, and PHP scripting atop the ngx_lua VM (by the corresponding X -> Lua compiler). grin We'll eventually get there.
