In regards to your comments:

1. relaxed guarantees, "As a consequence the LMAX team puts a lot of attention into ensuring the input events are fully valid before doing any mutation of the in-memory persistent state.". It looks like they deal with inconsistency at the business logic level instead of delegating to the persistence store. Probably, they don't have very complex transactional logic.

2. Smart data structures, here http://disruptor.googlecode.com/files/Disruptor-1.0.pdf you have a deeper technical view of the Disruptor and the rationale behind "mechanical sympathy".
The main thing preventing appliances from becoming future proofed is crappy parts(mostly the mechanical parts). For example, in the past a washing machine had lasted 20 years. today it's 3-4 years.

There are high end brands who have a guarantee of more than 10 years, but they're expensive and the cost per year comes about the same as the cheap ones.

Japan's IT exodus: A personal perspective
> If you ask most people what stopped them from reading their entire programming book (and we’ve talked to hundreds of people), it’s almost always that they aren’t motivated enough. In school, learning is motivated by report cards and teacher expectations. We hope we can build a motivational experience that pushes anyone to program - not just the stereotypical developer.

Badges and achievements are awesome when done right, but will only go so far with motivation. Real, intrinsic motivation will come from realizing that you can create something with the skills you've learned. If you could somehow capture this in Codecademy I think you could score a decisive advantage against the traditional tutorial/book learning model of learning to program.

Context: I'm currently working on a spaced repetition app that schedules Japanese vocab/sentence flashcards for you. While it has achievements/badges for behaviour that's conducive to your Japanese learning, it also finds native content on the internet that you're likely going to be able to read 90% of (based on the vocab cards you've done well on). Realizing that you can actually read Japanese content for native Japanese (i.e. you can actually _use_ the skill you're learning here) is the biggest rush of motivation I've experienced. It pushes you to go on and see how much more you could do, way more than any badge or achievement could.

SIMBL is a non-standard 3rd party framework. It would be more correct to say that SIMBL isn't keeping up with OS X development.
Soursop  Fruit As a Cure For Cancer
Really soursop fruit can be used as a cure for cancer? Nutrient content and usability of fruit, flowers and seeds of soursop / tailings to health, especially for cancer treatment, hemorrhoids, liver disease, ulcers, eczema, rheumatism, lumbago, etc.
The author responds to this point in one of the comments; I quote:

this is -- and I make no pretensions otherwise -- theoretical physics. It's not airy-fairy pie-in-the-sky speculation, but it also isn't proven the way you would prove that a * b = b * a. You may want to read this recent guest essay (http://scienceblogs.com/startswithabang/2011/10/guest_essay_...) that does a wonderful job of explaining, with some brilliant metaphors, what this sort of theory is (and isn't).
It's even older, it belonged to the GPO (General Post Office) before that, which is why it is yellow... the post office was yellow before it obtained the royal charter, renamed and rebranded.
As far as I understand three of the key features are:

1. Reduced queue contention: queues are typically implemented with a list, e.g. linked list, this introduces contention (queues spend a lot of time empty or very full) for the head and tail of the queue which are often the same dummy node. The ring buffer removes this contention.

2. Machine Sympathy vis a vis cache striding and ensuring concurrent threads are not invalidating each others level 1/2 cache.

3. Pre-allocation of queue data structures to ensure GC is not a factor.

Personally I think the LMAX team have done well in advancing the state of the art in what is often a key component in event driven, high throughput low latency systems such as those used in banks for trading, exchanges and market data.
Guess it could be a case of bad foundation, causing it to slowly sink into the ground over many years. Judging the type of ground of the excavation site at the photo, it seems to contain a rather high amount of clay, which is a terrible foundation.

I think you got confused...

I currently work for Yell (multi-national, been around for ever).

But, I have been working on a startup in my spare time for which I've now (as of last week) quit my day job to fully commit to.

The startup has no money and will be the definition of frugal until we turn profit, Yell has less (they may make tons from sales and be profitable quarter to quarter, but they're saddled with amazing levels of debt).
> It looks like they deal with inconsistency at the business logic level instead of delegating to the persistence store.

Actually it looks the other way around. As I read it, the "Input Disruptor" does the validation.

Do the three components all run in the same thread, or are they on different JVMs?
My goal was not to defend pure empiricism - that justifications for knowledge can come only from sense data. I just wanted to emphasize that, in your example, when we chose a good explanation instead of a bad one, the goodness of the explanation has a large empirical component.I am guessing that you agree with this but would focus on the non-empirical component.
One non-empirical component of its goodness would be the complexity of its specification, the Kolmogorov complexity for instance.
AFAIK image recognition already works on down-sampled images, even if the high res version is available, because the algorithms are too expensive and the details are not that important or even hurt.

I guess not. You need to create a marketing strategy to promote the app. 5k monthly users won't give you anything decent. You need approx 500k visitors to get the ball rollin'

A carefully constructed (cause n effect) marketing strategy can make your app a success. So start mind mappin'
The Disruptor components are not part of a single threaded process, as far as I understand

"Also these three tasks are relatively independent, all of them need to be done before the Business Logic Processor works on a message, but they can done in any order. So unlike with the Business Logic Processor, where each trade changes the market for subsequent trades, there is a natural fit for concurrency."

I think that the Disruptor can run on the save JVM as the business logic, also to avoid remoting-related bottlenecks.
Typically, excavation of ancient peoples' objects has been a very high-priority thing for most people - there's generally a lot of pressure to uncover these artifacts and get a "better understanding" as its usually while in reality being just a big curiosity and a huge source of entertainment.

Just look at the billion dollar business in ancient Egyptian artifacts and momenta, and the attention that new finds in the Nile bring.... and before you say that's not necessarily comparable - look at the at least millions of dollars tourist budget the Easter Island heads have generated each year.

People just LOVE to talk/gossip/guess/BS about past civilizations, and I'd seriously imagine the only reason no one has bothered to dig up a head is simply because no one believed there was anything more to it than a head.

Then there's the fact that we very much call them "heads" - doesn't that speak volumes for the fact that we don't think they have bodies? I also believe there are a number of theories floating around about why the ancients only made heads and not whole bodies (which is absolutely laughable right now).

>Apple clearly sees iOS and its locked-down environment as the future and Mac OS X as the past

Citation needed? Or are you pulling that from OSX getting a dose of iOS UI? The existence of the app store is merely a sign that they make money from the iOS one, and wish to make more money.

SIMBL is a hack used to load hacks (a fantastically useful one, don't get me wrong there). Its very nature is fragile, and Apple has zero responsibility to make sure it continues to work.

ISCHEMIC HEART DISEASE (HHD)
Population growth has some worrying trends if you start thinking in historical time frames. If we continue to grow as is, until we reach some sort of natural barrier we double the population ever 50-60 years. What will the world look like with 25bn (100yrs) or 100bn (200yrs)? What will it look like @ 1 trillion (say 300- 400 yrs)? Somehwere between 50 & 500 years from now we may know the limit. That's not that long in historical terms and it will probably be a recognizable world. Most of the same countries & cultures will probably still exist. Elvis might still be popular.

If growth does stop what will stop it? Culture (ie middle class western Europe) or something "natural" like famine?

If nobody makes WebOS devices, is the division really operating?
It depends where you are coming from I suppose. Kiosk mode until recently didn't really fit in with the Mac (going way back to System 1.0 days) work flow, but when Apple integrated multiple desktop into OS X, it shifted the workflow enough to allow for kiosked windows to inhabit their own 'space'. It's worth checking out as it's quite an elegant solution. I, and I think the vast majority of Mac users would agree on the resizing point and thankfully it has been addressed, but it's worth remembering that the original idea behind one location to resize windows was overall simplicity. Whether or not simplicity was achieved however is an entirely different thing, and I imagine that we'd agree that it wasn't! WRT to short cut keys, they have always be displayed in the menu. Since the menu bar is the primary way that many functions are initially accessed, the idea is that eventually the users will learn them through exposure, which in fact is exactly the same way that most desktop UI educate users.

Interesting, but having seen wine experts reasonably regularly pick out not just expensive v cheap, or white v red, but also grape variety, year, region, and even in some cases specific slopes in blind tasting, I think it says more about the expertise of the undergrads than about the ability of people to do this in general.

I can certainly tell Coke and Pepsi apart in blind tasting. I've more than once requested Coke, had it served in a Coke glass, thought "this tastes a bit odd" and checked at the bar to find out that it was coming straight out of a Pepsi dispenser.

The random songs from God need to be judged. It's work. I suggest rating a bunch of raw songs all at once. When doing a lot, your sense of taste is better. I like melodies that have a "voice" I guess they say. I half-heartedly estimate it would be damn-near impossible to make a computer judge melodies... maybe some neural net voodoo, I guess. Whatever.

There is some realation between what you offer and how God responds, but it's fuzzy. I think it's important not to forget your job of holding-up your end of the conversation. God will not let you stay passive. I think the notion of "offering" is good as opposed to just running the program without a second thought.

Even power users usually want consistency and ease of use.

The main advantage of Ubuntu is that it is the best supported Linux distro out there when it comes to software.

For allot of desktop centric software , supporting Linux basically means supporting Ubuntu and possibly fedora.

I'm a developer but I still want the option to be a "dumb user" allot of the time when I'm doing tasks like using the web / playing music etc.

Anillos de compromiso
El anillo de compromiso es el primer paso hacia la boda.
Bien, esto quizá es la primera vez que va a regalar una joya, y ademas va a empezar con una joya cargada de símbolo, y bastante difícil de eligir. Vamos por pasos. Un anillo de compromiso no es un anillo de boda. Es a la vez simple y complicado. Con un anillo de compromiso usted va a sorprender. A declararse. A mostrar que conoce el gusto de su pareja. Un anillo de boda es distinto, mas formal.

No, it's a lot more than that. It is a practical method for awakening to aspects of life which most people hide from. Though you wouldn't know it from content-free, gossippy BS like in the OP article.
But bonus is.
Christianity has one way into heaven, baptism, but beyond that things diverge quickly. It's better (IMO) than believing different religions but acting the same in practice. As Chesterton put it:

"So in Christendom apparent accidents balanced. Becket wore a hair shirt under his gold and crimson, and there is much to be said for the combination; for Becket got the benefit of the hair shirt while the people in the street got the benefit of the crimson and gold. It is at least better than the manner of the modern millionaire, who has the black and the drab outwardly for others, and the gold next his heart. But the balance was not always in one man's body as in Becket's; the balance was often distributed over the whole body of Christendom. Because a man prayed and fasted on the Northern snows, flowers could be flung at his festival in the Southern cities; and because fanatics drank water on the sands of Syria, men could still drink cider in the orchards of England. This is what makes Christendom at once so much more perplexing and so much more interesting than the Pagan empire; just as Amiens Cathedral is not better but more interesting than the Parthenon. "
Making the Linux desktop simpler requires much more than changing the UI.

I'm not sure the ATM is the best example, at least for simple transactions like withdrawing or depositing funds. Aside from the social interaction with a teller, using an ATM doesn't save me much time or work. Self-checkout kiosks at the grocery store, however, allow the business to push costs on the consumers because scanning and bagging my groceries does require more effort on my part. I'm not sure that is contributing to more fatigue (perhaps this is due to people working more hours?), however.

What is plainly true, however, is the rise in such self
service. And the question of how this affects us, is interesting. I would speculate that one of these effects is an increase in anti-social behavior.

And this, I suspect, is what Illich was most interested in. (I've not read this particular book, however).

It's the same reason why 'heaven' has a problem. If heaven is what you want, you can just install yourself now on a morfine or heroin drip, wait till you die and hope it exists (not that you will care at that point). As a child Jehova witnesses rang my doorbell to explain heaven;

"Heaven is like a growing garden, with all the fruit you want!"

"I hate fruit"

"For you it's a garden with what you want!"

"MSX computers?"

"If that's what you want! And there is no pain and suffering; it's only great!"

"If I die now, I won't miss my parents?"

"It will be only great!"

"But how? My parents and sister and friends are not there?"

"You won't remember them!"

"Eh...."

"It will be only good for eternity!"

etc.

Heaven makes no sense at all, nor does utopia. We need pain and suffering to be alive. Hopefully not too much, but too little is so dull, you can just sniff dope 24/7. He is right about that; all scifi has crap; Voyager is kind of utopian (no need for money in the federation, enough food etc), but they still need conflict.

And the MS world is not utopia; that's MS utopia (maybe) (making tons of money because people sitting in front of screens). BillG went for the cool aid to talk to computers many years ago, SIRI makes it happen now, not by MS. We are in utopia now (in the western world) by many past definitions.
