Off-topic slightly but the thing I loved about that was Picard would routinely have several on his desk as if other crew members had handed them to him with reports to review on.

So you invented the tablet computer but not cloud computing? Or even network file shares...
Borders stores were packed during liquidation sales, despite the fact that there were few real bargains to be found. People love a perceived bargain.

Don't conflate Apple's high-margin & (relatively) low-marketshare/volume computer business with their high-margin & high-volume iPad/iPhone business.

In order for someone else to win on price, they are also going to have to beat Apple on cost. If a Dell laptop and an Apple laptop cost the same, who would ever buy a Dell? And the prices aren't even close, sometimes Apple is 2x the price of a Windows machine (and yet people still choose to buy Apple). But in the tablet & phone space, Apple prices are not much higher than Android/WebOS/Wp7/Blackberry. And Apple's costs are clearly lower.

There are a lot of reasons why this is so. Right now Apple has their own distribution network, the other guys generally don't. Apple has better brand value and has negotiated killer deals with the phone carriers. But at the end of the day the most important factors are the volume & the narrow choice of parts.

Apple has more volume than anyone else, by an order of magnitude. That means they get better prices from suppliers and they can spread their fixed manufacturing costs across more units. Higher unit numbers always leads to lower unit costs for a lot of reasons.

So if you want to compete on a device that is close to the iPad, you are going to be really hard pressed to beat the manufacturing cost unless you ramp up to build the same number (which is super risky if they don't sell).

The only way to get a lower manufacturing cost is to buy components that are lower level than the iPad. This is what happens in the computer business. Going back to Dell v Apple, how many people really would argue a $700 Dell is better than a $1200 Apple in the quality? Maybe in value, but not in quality. In the tablet & phone space, there are not as many corners to be cut. You can fill a computer with a cheap motherboard, hard drive, etc. You can stamp out a crappy sheetmetal case or mold some plastic rather than machine the case like Apple does. Most people won't notice the difference becasue you interact with the computer through peripherals.

On the mobile device the big cost drivers are hard to skimp on. A smaller battery makes a functionally inferior device. A crappy case or screen impacts the look & feel of the device in the way a case on a desktop doesn't. There are few options for CPUs and we don't have the same extraneous CPU cycles like in the computer world so a crappier one is very noticeable.

So how do the other companies get to a lower cost? I just don't see it happening without making a drastically inferior tablet, and I don't think people are saying that tablets are unnecessarily powerful right now.

Ask HN: How many people needed for effective A/B testing?
Hi HN,

I run a review website (similar to Yelp) for a niche business market. Currently, business owners can manage their listings for free, but I would like to make some money now by offering additional features. I don't know if I should offer one premium tier for say $29 a month with all the features, or multiple tiers ranging from $19 to $39 a month depending on what features they want (think: premium, platinum, ultimate).

Before I create any of these features, I'm going to see if my current customers are even interested in paying for them. So I was thinking of doing A/B testing, where half of my customers would be informed about a one tier structure, and the other half about the multi tier structure. But here's my problem: I only have 170 people who are currently signed up to manage their business listing. Is it worth doing A/B testing with such a small population? Or should I just pick one option and go with it, hoping for the best?

TL;DR: Is having 170 people too small of a population to do effective A/B testing?

Thanks!

EDIT: changed the wording to use correct statistics terminology.

The 'exactly' part is especially funny, given that the tablets have a different screen size and aspect ratio, as was obvious when people looked at properly scaled photos side by side.
You have to wonder at what point the speed test server itself becomes the bottleneck. I bet the connection is actually faster and I'd try running a few of these simultaneously to different locations.
I guess one way to compete against this set of affairs is for someone like Intel/Microsoft and define a Platform like ATX for PC's.

* Whatever your solution demands, there's a way of doing it. What the solution doesn't need - nor even cares about - is the philosophical argument.*

I think the disagreement here is that you seem to believe that philosophy is engaged in some different activity from the kind of "how should X type relate to Y supertype and Z characteristic" is the meat of object oriented design.

But really, what is being here is ontology. Ontology isn't really fancier than this and the here isn't more clear cut that what philosophers try to muddle out.

Ordinary philosophy has been kind of society-wide clarification of definitions, just a design is an organization-wide clarification of definitions. Take a look at the actual text of The Critique Of Pure Reason at some point. While might have been written with various arguments in mind, most of the actual text is a long, long discussion of what objects belong in what category - ie, nothing more "airy-fairy" than most design discussions.

Ordinary philosophy gets less attention than the elaborate debates around the "edges" of definitions. But this also happens with design discussions.
Doh. I honestly misread that line. Thank you.
I think a whole lot more people would pay $30 a month for a tablet. If you can just pair that with some seemingly valuable service with a low variable cost, you'd have a winner.

Curious to see where they move check-in and location integrations. I've noticed they've been using my foursquare data to show me "Which place do you like better?" in the sidebar. They could do a lot more recommending of places like restaurants, bars, stores, and tie in deals.
Confirming this. The experience of a Americorps recruit is barely comparable to the average experience of a professional teacher. Americorps recruits are sent to the worse schools, partly because those schools cannot afford more professional teachers.
Quick plug - I host a lot of my friends websites for them on Webfaction. I uploaded a theme from Woothemes for a friend that contained (without me knowing) an outdated version of timthumb.php. Webfaction emailed me that the plugin was outdated and automatically upgraded it to the newest one.

I've had no complaints with them and if you're worried about this sort of activity you might want to consider switching to use them as a hosting provider.
They are supposed to be tablets and are actually moved in the film. This whole sequence has a lot of footage of the tablets: http://www.youtube.com/watch?v=3vEDmNh-_4Q

Here is an excerpt from Arthur C. Clarke’s book:

“When he tired of official reports and memoranda and minutes, he would plug his foolscap-sized Newspad into the ship’s information circuit and scan the latest reports from Earth. One by one he would conjure up the world’s major electronic papers; he knew the codes of the more important ones by heart, and had no need to consult the list on the back of his pad. Switching to the display unit's short-term memory, he would hold the front page while he quickly searched the headlines and noted the items that interested him.”
Please take this as a quote and as tongue-in-cheek, but during my (very limited, I know that I'm not representative) military services the 'US grunt' was one of the things our superiors made most fun of.

'Follow orders blindly' (which is more or less the thing we're arguing about) was actively discouraged from the leadership.

Is this good? How can I tell.. But since I started out biased (i.e. with a working brain) I did enjoy that part of my service.
>>He has several arguments; performance is only one of them.

First -- I noted that I limited my comment to scripting languages.

I did discuss most of the relevant arguments in the article, so I really don't see what your point is?

It doesn't matter for the scripting languages that a regexp lib is large (it is linked in and used anyway), so I ignored that. I also ignored the Unicode point, since it is generally supported in scripting languages' regexp engines.

I did touch on speed and development speed. Shorter code is also generally easier to understand; a simple regexp can often replace 10-20 lines.

In my edit, 10++ hours before your comment, I discussed when full grammars where a better alternative -- so I handled Pike's accusation of treating Regexps as a "panacea for all text processing". (I have used regexps as lexers for grammars. But only for parsers of less than a few hundred lines.)

(I am not going to touch Pike's argument if I and others really grokk regular expressions, because I thought I did understand them until I read "Mastering Regular Expressions". Maybe there are some more satori insights waiting? I do consider myself a little bit familiar with them from automata theory, implementing state engines and usage [Edit: and my considered opinion is that re:s are often a good solution for scripting languages.])

Considering that tag approval has been a popular user-request for years, I don't think their holding back those changes looks good for them... consequently, I doubt they've had it in the works.

They did move fast to "pivot", however, and I applaud their recognition that finer-grained privacy is an important user "feature/requirement".

i would say, it depends on the results, if from the 170 you get a contundent answer then I would say its a go, if results are not contundent enough you can keep your a/b running until it does

My point was that that a govt or bank can't "cheat" by leveraging it or counterfeiting it. Yes, if very large accessible reserves were found, one's savings in gold would be hurt but it would would not happen simply at the diktat of a government. The fact that you can mine it or produce isotopes does not change the fact. I did not say anything about its inherent value.
Finland, according to the article, hires the top 10% of graduates, who also require master's degree in education. So they're starting off with a highly skilled base of top candidates. On this side of the pond, there are decades of poor teachers ensconced in the system.

5. Science Exchange if this works, it could speed up R&D tremendously.

As a former student in a small town elementary school, I have little doubt Matt Stone and Trey Parker based the South Park school on their own experience growing up in Colorado. Mr. Hand is a bit much - but just a bit. Putting up with bizarre characters, listening to inappropriate personal life details, tolerating dumb lessons and watching videos in class were all standard occurrences.
Phishing attacks were a good example, but I don't feel like I'n being too critical! It's a good concern.

Similarly: I'm hoping that you're also someone who's annoyed when Windows hides extensions. Yes, you can figure out how to restore extensions so you always have the extra piece of information--- but can your mother? Can your nephew? These computer users are learning less about files has "conveniences" them with simpler filenames.
It would be a very interesting privacy problem if they do that. Considering that they strip EXIF data before adding your photos to your albums etc.

Given six million people, who all are smart as hell when 15 year olds, you could assume that there would be at least one university in Finland that would be in the group of 30 best universities in the world.

I have heard that Finland has quite cheap engineers when compared internationally, but you can hardly speak of very high class upper education.

Teaching in Finland is far from perfect. I think these scores have a lot to do with language. As Finnish is written phonetically, average child knows how to read and write after first grade. It would be more fair to compare Finnish 13 year old with English speaking 15 year old.
I actually found Facebook's check in functionality to generate more discussion among friends than Foursquare. The big problem from me is that I wish they could have come up with a better way to restrict who I'm showing where I'm at similar to Google+ circles.
I wonder if some of the inventors of the airplane were disappointed to see it used for military purposes, or if it's just my 1990s upbringing that makes me think of the Internet as something beyond the trivial concerns of humanity, and use of it as a battlefield as tragic.

This is a really good chart. The software industry as a trade is starting to hit a second level of maturity. As such you are starting to see specialization within the various disciplines. Those specializations are starting to have common tags associated with them that are recognizable. This is actually a good thing, because it helps vendors of those services clearly convey what they do. MY company is a UX house specializing in JavaScript based web apps and Mobile apps. We are heavily skilled in the Information Architect and Usability Analyst disciplines, which some other front end house are not, with tags that quickly summarize a concept it makes our job easier to convey that we offer so much more that just development services.
Site looks great. This is pretty similar to an idea i had a few years back: http://buyersvote.com/categories

It has languished since and never took off, but the pieces were all there: user generated listed, votes, wiki style edits, comments etc.

I've had some time to think on why mine never took off and wanted to share a few ideas in case it helps.

- critical mass is hard, StackOverflow (my inspiration for it) was able to launch with two massive blog posts from influencers

- how to counteract this? either empower your users to create their own "sub-listries" and try to attract influencers

- or do the bowling pin strategy http://cdixon.org/2010/08/21/the-bowling-pin-strategy/

- or do the tripadvisor approach (read Founders At Work for this story) and spend massively to seed content for several years to reach critical mass on your own

Few other thoughts:

- I think your design is better

- Is "Articles" the right word here? Esp given your domain would "lists" work better?

Hope it helps!
Ping measures the round-trip time, so it would really be twice that.
It would seem. But I suspect this wasn't so much a result of the writers' lack of imagination but rather their need for a concrete metaphor to show virtual operations.

A more fully thought-out future might have a desk that was a hologram where virtual reports are still "stacked", with these serving primarily as a metaphor for both Picard and those watching Picard (they could judge how busy he was by how many "reports" he had stacked on his holographic desk).
You can pretty much knock any coding skills right off the table for the majority (90%) of UX disciplines, to include anything in terms of delivering production-ready code or making any type of technical decisions regarding stack, frameworks or languages deployed on the front end.

That being said, it makes me queasy that Information Architects still get a seat at the table with their current skill set. At a consultancy, this type of breakdown makes sense as you're trying to get as many billable bodies on a project as possible and bombarding the client with as many prototypes and information as possible is part of that strategy, but in a start up, I find myself providing user research, analysis, interaction and visual design along with all of the front end code (js, css, html) as well as building many of the jsp's.

tl;dr: gonna print this and show it to my boss the next time he asks if I have something to do.
I don't know if this has been mentioned previously, but I've not seen it in any of the previous debate about software patents.

Quoting from the article:

Patents are meant to foster innovation by protecting the inventor and then upon expiry providing a library of information for others to build on. To this end, going forward, if a patent doesn’t actually tell you enough information to understand and build the invention, it shouldn’t be valid.

Given that a software patent is...well, software, why not require that actual working code be submitted as part of the patent application/grant? The code is held in escrow/confidence by the patent office for the term of the patent, and is released to the public domain when it expires.

There's probably some issue there with copyright of the code that might complicate the public domain part, but at the very least you could clean-room reimplement it. An alternative might be that you are required to renounce/void copyright on the code in order to obtain a patent - the short term monopoly of the basic idea comes at the cost of no long/indefinite-term copyright on the specific implementation.

That opens up all sorts of new possibilities, like requiring/permitting the patent claims to be machine-readable, in the sense of a conformance test-suite. That both ensures that the provided implementation is a true instance of the patented invention, and gives the holder/patent office/court an easy way to check for violation.

Ok, hold on. This page totally just got updated and some links/listings were removed. I printed it to read at lunch 45 mins ago ... I came back and refreshed and a certain listing was gone (wanted to hit the link).

What's up with that?
Well, ping is relative. In Norway we generally have around 6-8ms to Norwegian Internet Exchange, and typically end up at around 30-40ms to most parts of Europe. At some point distance will get you. Regular cobber is not actually slower, but the equipment connected to it is, and that is why you usually see at least 30ms+ just leaveing your ISP network.

For instance, if you're using WLAN you might end up doubling your response time. Something to keep in mind if you're a latency freak like me!
