you rarely hear people complaining about messaging not being fast enough in Objective-C

There was a big spate of it ~4 years ago -- people had been using method dispatch in tight loops, and boggled a bit at the numbers when they started using Apple's fantastic Shark profiler. objc_msgsend is as cheap as dispatch can be without static linking (way faster than Python or Ruby), but it's still much more expensive than a C function call, and there's nothing keeping you from trading your square brackets and colons for parens and commas.
Thanks for the clarification. There is a big difference between saying that one $50 app did well and saying that "Figures show that the top grossing apps were $50"

As itunes stats show (today), in the top 100 grossing apps list, only three apps are $50 or higher

No, Jefferson was wrong, plain and simple. The American Revolution led to a net decrease in liberty. By the 1790's taxes were higher than they had ever been under the British. The war itself force tens thousands of loyalists out of their homeland. Tocqueville wrote: "I do not know a country where there is in general less intellectual independence and less freedom of discussion than in America. .. . In America the majority builds an impregnable wall around the process of thinking."

ALS run in my family too.

It gave me a new kind of importance and focus to living fulfilling happy life instead of goofing around (although I see goofing as an integral part of human life too) when I realized that there's a really high chance of getting ALS in twenty years.

Hal's attitude is a really admirable. However, for me, one of the key requirements of living in respirator is to ability to communicate with other people. Is living worth of it, if you are not able to communicate with outside world, and you know that you never will.

It's tough question, and in ALS, you have to make a decision when you still are able to communicate, when you still can nod or move your finger to say that I've had enough.

Actually I was looking to build a collab whiteboard app myself some time ago, but then I decided to focus only on one, the one I am currently building.
I explored what is out there at that point of time and I found quite a few, a few good one's will be http://www.jotspace.com/, http://www.instructure.com/ [not a whiteboard, more of other collab features],
http://etherpad.com/. Check them out.
That interest was the reason why went ahead and explored it.

Quick Money Making Methods in the Internet
Is there really a quick money making scheme these days? If you are among those persons who have doubts about making quick money, then better start believing now and embrace the quick money making promise of the Internet. More and more people are now into internet marketing. The reason behind this is the convenience of working from the comforts of your own home, with no boss around, and just you and your marketing skills to deal with.

Yes, it will take some knowledge and skill on how to run your online venture, but once you have mastered the ins and outs of internet marketing, expect yourself enjoying a stable surge of income that you thought you can never earn in your 8-hour job.
There are various quick money making methods in the internet and here are the list of a few common ways:
• Sell products on auction sites – You can sell products on auction sites and this is probably what people think when talking about online business. This is a lucrative way to make money online, but there is one thing that you should be aware of – your item may or may not sell! So, ready yourself with that. Also, if you want your items to sell, make sure to implement powerful marketing techniques.
• Go for paid survey sites – There are several ways to make this work and one is by completing various offers. Some offers are free while some require payments, but almost all are quick money making. However, a drawback from survey sites is that, you won’t probably be making a full-time income. This is a good idea if you just want to make a few hundred dollars a month.
• Affiliate marketing – This is the real easy money making method. The idea is to sell someone else’s products or services, and earn big time commissions. This means that you need to have websites to send people to and a product to promote.
These are all brilliant quick money making ideas. But no matter what methods you choose, there is one thing that you should give focus on and that is good MARKETING!
Refactoring doesn't have to be massive. Perhaps you can get by with a subtle tweak, so long as it's well thought out.

Alternatively, if adding a feature demands a massive refactor, then it might be a warning signal that you've got some fundamental issues with your UI. In that case, it might be worth it to spend the time re-examining the core design of your app.

You also might refuse to support that feature. Being able to say "no" is an important skill, both as a designer and a developer. Leaving stuff out is often as important as putting it in.
In the UK, postcodes - unlike US ZIP codes, they're not free

Retail product data - books, movies, music, games, electronics, etc: you can kinda do this through affiliate programs, but it's not great

Drug companies - studies can be killed if the data looks bad; we should be able to see every study, completed or not, and all the associated data so we can do comparative analyses

Actually we're also able to spend a lot more time now on things that really matter to our customers -- things that customers request, like more graphing options and better support for cloud instances. The cloud functionality is already available, and graphing is coming up fast. It's a real pleasure to finally have time to address these things, in addition to the sales and partnership efforts.

Also, performance is significantly better since we simplified the architecture (http://blog.scoutapp.com/articles/2009/10/01/simplify-get-an...), which benefits customers old and new!
Ways To Earn Extra Money
So you want to make money on the web and want to play it hard in order to earn massive income. It is a fact that there are lots of ways to make money on the internet, but the question is – where to venture and what internet marketing methods are you good at? You need to provide answers to these questions before you can become big-time online marketer. Once you have set your goals and decided what make-money methods to do, then harness it and work it! But if you still don’t know what money-making methods to venture on, here are some ways to earn extra money …

• Market your products or other people’s products/services – This is the best online business that you can venture on and one of the ways to earn extra money. There are specific niches for just about anything online and there are vast opportunities out there that can walk you through and begin making money in the internet.
• Write e-books – Millions of internet surfers these days search the internet to find all sorts of information. With every new product, service, or idea, people are always trying to find information and this is where e-books come in. These are digital versions of books which people can find the information that they are looking for. This is one of the brilliant ways to earn extra money online.
• Affiliate programs – These are designed in order for the owner of products or services to make money as well as provide commissions to those who do the marketing. There are vast affiliate programs online and all are excellent ways to earn extra money.
• Write marketing articles – This works in two ways – either you get paid to write articles for other people’s products and services or you write marketing articles as ways to earn extra money thru article promotion. Whichever you choose, both are money-making.
Amazon. One can see sales trends of every book, cd, dvd, clothing, and electronics store across the world. This would be amazing.
5 Things Mind your Facebook manners?
Social-networking sites can be a career boon - if you don't annoy people in the process.
Come to think of it, does anyone know if Amazon doesn't turn around and sell sales data back to competing manufacturers? This data would be a huge benefit in terms of where to focus advertising money and bundling efforts.
Maybe, maybe not. What would be interesting is a longitudinal study about this.

I can believe that ten years ago people didn't scroll, but instead our behavior changed over time as we adapted to the medium.

So, ten years ago "users don't scroll" was good advice, but designers made the mistake of filing that away in the Known Fact bin without reflecting more carefully and/or actually testing it.

Just a hypothesis.

Beckman's an interesting character, and he asked intelligent questions. I was unaware of him before this (I don't know anything about the M'soft or CLR worlds) but I'll have to keep an eye out from now on.

After a mercifully short Lisp intro (parentheses, prefix notation, programs-as-data and the macro system) Hickey spends most of his time talking about Clojure's seq abstraction, immutability and persistence, constant-time modification to existing structures, and the STM.

Not an interview for complete neophytes, their conversation includes offhand references to fp, monads, functions as first class objects, OO classes/methods and other stuff they didn't bother to explain. IOW it wasn't dumbed-down. This is an intro to Clojure for not-stupids who might not have seen a Lisp before, but that's okay -- they don't end up talking all that much about Lisp.

A compiler I worked on actually did this for all function calls. With recursion impossible (and whole-program compilation mandatory), huge gains can be made. And that compiler is used for pretty significant applications. Odds are many posters here have its microcode in their pocket.

did you try implementing nested sets?

The big thing we needed to do was a rolling archive to progressively broader timeframes. As metrics come in, we keep every single datapoint for the first 6 hours. After 6 hours, data gets rolled up into 5-minute archive. Each datapoint in the 5-minute archive then contains avg, min, max, etc for all the points that lived within that 5-minute span.

The archiving carries on through progressively broader windows as time goes on -- a 10-minute archive, 1-hr archive, etc. This progressive aggregation is the only sane approach to storing the massive amount of data we get. And, it reflects the need for higher resolution for recent events -- it's rare you need to see what happened at one exact minute 6 months ago.

It was this progressive archiving that bit us, specifically as DB performance degraded over time with lots of insertions/deletions. Nested set didn't/wouldn't help with aggregation costs and degradation from churn during the archiving process.

Hope this helps -- I'm going to try to do a more technical post on this in the future.
The article says, "He [Gandhi] sang the praises of Subhas Chandra Bose"

And indeed, in 1942 Gandhi called Bose "a prince among the patriots". Source: http://en.wikipedia.org/wiki/Political_views_of_Subhash_Chan... Wikipedia says that this was a "a reference, in particular, to Bose's achievement in integrating women and men from all the regions and religions of India in the Indian National Army." The source for the wikipedia quote is The Collected Works of Mahatma Gandhi.

Thus it seems that the claim from the article is indeed correct, albeit it one-sided.
Beware Book Learning
Even with offer to pay. At that time, there were too many startups and not enough partners/lawyers to take them all on. Maybe it was the sign of the times and things have changed.
The article did not make any "outright fabrications" with regards to Bose, see my comment below.

How can you quantify the amount of liberty in America???

Let's say taxes were higher, that doesn't mean a decrease in liberty. They fought because of taxation without representation, not because of high taxes.

So you're saying that majority rule in USA tends to prevent the smarter people from getting any power? I think what generally happens is that people who are smarter, and do things better, will do it. At least they have the ability to. Reality will prevail and reveal how much better they are, and then the majority will pursue the new method/idea.
RethinkDB seems to implement a functional btree on a log-structured storage. This would involve lots of copying, I wonder what is the performance impact of this (compared to a less pure implementation that copies the modified nodes every thousand updates or so).

Also, the most important feature for SSD storage (no random writes!) is fulfilled by Cassandra / BigTable implementations based on SSTables, I wonder how a btree-based implementation compares to them.

This is terrible. Is there any question left as to whether private healthcare is a disaster? I have known a few people who have been denied healthcare coverage when it is quite clear that it is due. Either there needs to be a regulatory board that can overrule insurance companies or we need to implement public healthcare.
Well, yeah, I know, magnetic resonance is a mighty cool hack. I was just hoping that it could be maybe, you know, a bit smaller. Not costing as much as a first class ticket from NY to Tokyo for a trip through one might be a nice touch as well.

I consider taxes to be a decrease in liberty, because I am no longer able to dispose of my income in a way that I please. Instead I am forced to hand some of it over, at pain of imprisonment. I have no actual power to prevent this.
The best way to get a lean streamlined application is by eliminating features.

Right, but let's be clear about one thing: If users had a say in which features were included, the number of features would be huge, and these features wouldn't all be just variants that could be educated away. They are real needs. So, not having these features means not to satisfy some user requirements.

Sometimes I get the feeling that we kid ourselves into believing that if we create a super clean, consistent UI that doesn't inundate users with features they don't use, we have somehow succeeded. Most of the time we have not, because for each individual user the application most probably lacks very important functionality.

A user who repeats the same laborious steps day in day out in order to achieve something with my software will gladly accept any number of useless features in his face just to get that one feature that makes his/her work 10 times more productive.

I'm afraid UI/feature minimalists will never understand why on earth so many people will pay $650 (or whatever) for MS Office, the mother of all feature monsters.
Mint.

What do people invest in? How do they spend their money? How do they lose their money? I'd love to see the kinds of insights that could be gleamed from it. Of course the data will have caveats but I could see reports like: 90% of mint users who own apple stock also buy apple product or maybe 90% of users who buy apple product short microsoft stock?
As you state, there is a lot of evidence that everybody uses a different 20% of the features. However, I think that primary applies to horizontal apps such as operating systems and core office productivity suites.

I recall reading on Jensen Harris' Office 2007 new UI blog that they tried their damnedest to remove features, but no one could come up with any reasonable way to pick any features to cut other than a select few which were practically unused by anyone. They had extensive usage data to work with. Meanwhile, the feature-poor Windows Live Writer has taken off like a rocket for bloggers.

That may be true for something like Excel, Word, Linux, etc, but I think that wouldn't be as true for vertical applications. Sometimes, I wonder if would be better off turning the core word processing components into a library and releasing verticals for different types of writers. Professional writers, for instance, probably don't need any formatting tools other than headings. Blog writers should only use things that can be represented well by typical HTML blog engines. Etc.

I think this is a case where the advice that is right for startups (typically verticals) is not right for the big guys. As a little guy, I'm betting on nailing 20% of the features and scoring 18% of what people want :-)

Though the one thing I kinda wish it had is an undo button -- if I accidentally remove something when I don't really want to, I'd like to not have to reload the page and click in all of the areas again (except the last one, of course).

I guess that would mean keeping track of what the last div/span/whatever you removed was, which I guess might be a little too involved for a bookmarklet. I wouldn't know -- I'm no JavaScript wizard.

and its great to see that people are working on removing the hurdles that it takes to create web/html application.

but i wonder how this whole web app stuff breaks up once we move away from WIMP to more task oriented applications with NUIs.
I haven't looked at the code, but I suspect they're just using display:none to hide elements. There's no reason you couldn't use an array as a stack so that you could keep track of the identifiers for the elements that have been hidden and then allow an undo mechanism. For elements without an id you'd add something of your own, probably a cssclass. An undo system is not too difficult to implement.
