I'm thinking Apple could eventually use iMessages + FaceTime to dig into Skype's userbase. Especially if they make good on their "open protocol" promise, which would bring clients to other platforms pretty quickly.
The only thing I took away from the post is Siegler's inability to see that C(n, 2) is much, much less than C(n + m + k + p + q + ..., 2), where each letter stands for the number of devices supporting a particular mobile platform.
Not just that, it requires iOS5 which (AFAIK) won't be available to even 3GS owners.

SMS isn't going away anytime soon.
From what I can tell, it's a replacement for the current SMS/MMS app on iPhones (and new on iPad, sans SMS/MMSing). People you text messaged before can now be iMessaged instead for free. People with non-iOS phones can still be SMSed as usual. So it looks like the end effect for users is that they use less text messages the more iOS-using friends they have. I guess if the network effect kicks in and everyone in your social circle ends up with an iPhones/iPad, messaging each other will be completely free - no need for text message plans anymore.
I agree, and it's tough because someone needs to be the middleman in all this when it comes to messaging, because with messaging there is a guarantee of delivery even if the other party isn't online.

It doesn't mean that Apple, MS, Google, RIM can't all be a middleman for their respective users, but they certainly didn't mention that in the keynote.
Simple Custom Reminder API
I don't see how, given that Android devices aren't restricted to a single distribution channel.
That may be true, but what's the difference? If there's no reason to go looking for an app in the first place, it won't get found anyway.
It was part art, part joke. It turns out, it also fulfilled a real "need" people had: an interspecies gaming experience with their cat.

I want to improve the cat/human connection by letting the human use the iPhone to control the mouse on the iPad. Keep a look out for that feature in the coming months.

EDIT:

The hardest part about adding that feature isn't the bluetooth communication between devices. (That's easy, Apple provides sample code.) Rather, the most difficult part is designing an interface that is easy to use.

I can't tell you how many iterations we've been through to design a way to pause the game that is 1) hard for cats and 2) memorable and intuitive for humans.

I call this the Game-For-Cats-Law-of-Touch-Screen UI: any UI feature that is too hard for a cat is too hard for your average iPad user.

iOS 5 supports the 3GS.
Agreed. Both sides would need to learn a lot for that to happen. I think there's a vast chasm in fact.

Moreover, most academics don't have time for the wiki part. They barely have time for the papers part. Some academics get to write graduate texts because they can get credit for that, but that's about it. They do get time to write lectures to give to students though (sometimes barely).

But there's a problem. In mathematics, a result may depend on definitions, e.g. whether a ring has a unit element or not, which definition of natural number you are using, or which definition of compact, whether you allow the axiom of choice, what definition of norm you are using, or how a function is normalised. The actual results may be completely different in different books depending on the assumptions made and the precise definitions given. Language also changes over time. Sometimes the same word is used to mean totally different things, and the meaning depends not just on context, but era!

What happens in Wikipedia is you sometimes get a mosaic view of things which are not compatible. Only an experienced expert in the field can spot that and correct it, and it may be days of work to cleanly demonstrate why it is an error. Wikipedians can add such errors far faster than they can be noticed, corrected and justified.

The issue is that people think of science in a reductionist kind of way as a list of true statements. Books are lists of true statements and you can pick and choose the ones you understand and collect them together however you like. But this is totally false. Maybe the only reason you can even understand the book is because the author took pains to define things in such a way that a pedagogically sound route through the material exists.

In the mean time, academics are marking the same wrong answers to homework assignments and in written projects and dissertations over and over again. So this is a huge problem.

(This is to say nothing of the fact that many students believe that using quotations from Wikipedia without attribution in dissertations is permissible, presumably because Wikipedia allows this for public domain sources or something like that.)

What process or processes can bridge the vast chasm between what academics are trying to do on the one hand (advance the forefront of knowledge and disseminate it through teaching to the next generation) and what is being done on the other hand by wikipedians (collate human general knowledge in a way that is easily accessible to all)? There's a vast gap and it is precisely at the intersection of these two great enterprises that things are going woefully wrong.

This sort of sounds like Apples version of BBM.

Not sure if they are trying to preempt a rumored BBM "app", or just doing more extension of their own ecosystem.
I think the gp comment was rolling his eyes, not because Starcraft is bad, but because the term "better than real sports" implies that competitive Starcraft is not a real sport.
iOS 5 will definitely work on 3GS. I am skeptical about the performance on outdated hardware but I don't think it will be that bad.

any network's value is exponentially proportional to the number of users it has

Demonstrably false.

The most widely quoted version of this is Metcalfe's Law, that the value of a network is dependent upon the square of the number of members. However the best empirical evidence is that the actual scaling factor is O(n log(n)). Which means that competing networks of different size and coexist for extended periods of time. (A phenomena that has actually happened on multiple occasions.)
Why does it have to be good or bad?

It's just business. The only point to take away is, if you are considering developing something for the Apple ecosystem, take into account the business risk that anything you do that is highly successful has a strong likelihood of being "steam rolled". Don't delude yourself that you'll be able to pick some low hanging fruit and make millions. You'll either solve something hard and have a barrier to entry or you'll solve something easy and get steam rolled, hopefully after having enough time in the sun to make it worth your while.
No they won't. Focus on the broader ecosystem (Windows, Android, Blackberry, Windows Phone) and greater integration.
Did you even watch the keynote address? They specifically said 3GS.

For years Microsoft was/has been prevented from squeezing out 3rd party developers by the DoJ/Consent Decree. Why do you think Microsoft gives away an anti-virus product that you have to download and install separately? Because if they bundled it with Windows anti-virus vendors would lawyer up.

AT&T charges $20 a month for unlimited texting. That's $240 a year. In the two years of your contract, $480. Free texting would "pay" for the iPhone twice over.
One of the nice things about SMS is their reliability. Not having to think about whether or not your message arrived because of a friends device is nice. Maybe a fallback feature would be nice here?

This makes me even more curious for what Google is going to do with Disco. It seems logical for them to bake it into Android just like Apple is doing with iMessages. What if Google flips the switch and makes it cross platform – will they be the ones to eliminate SMS from carriers?
They're extending existing users time until June 2012, at which point it will be shut down as all of its features are in iCloud.

Show HN: We're taking on AnyBots
Hi All,

We built a prototype telepresence robot to go up against AnyBots. We're using an iPad as the control system and for FaceTime video conferencing. It took us a couple weeks to make.

We demoed it this morning for the first time:

The next version will be taller and thinner. What do you think? Do we stand a chance against AnyBots?

Thanks,

Will OSX Lion have the same upgrade options?
Sometime I do like to do a clean install. Will Lion allow that? I haven't read much except "downloads from the app store".
Yes, it is 64 bit only - Core 2 Duo or newer required.
| Everyone I SMS right now has an iPhone.

This is very funny. Is your last name Jobs?
Please leave any comments, tips, and advice that you may have. It will be very much appreciated. This is my first website launch and I want to know anything I can do to make the site better.
Facetime needs two years to get going. It's been on iPhone4, Mac, and iPad2 for 11, 5, and 3 months respectively. Once iPhone 3G/3GS and iPad1 users get new devices and Mac users buy/upgrade to Lion, FaceTime will be available to a lot more people. So, after this holiday season, I would expect FaceTime to be a much bigger deal.

iMessages can hit the ground running from day one, since it is available down to iPhone 3GS and does not need new hardware. Also, Apple merged it with the existing Messages app, so I assume it will decide whether to SMS someone or iMessage someone for you. It's a win for iOS users either way.
Ask HN: How to do a non technical interview?
We're hiring developers for HelloFax (YCw11) and I'm looking for ways to optimize the hiring process.

Here's how our hiring process works:

1. Technical screen (phone call)

2. Longer technical interview

3. Non-technical interview with the other cofounder.

4. We do a trial period or jump into full time employment (if we've known someone previously).

I think we do a solid job at #1 and #2 (thank you Joel Spolsky!), but I'm curious what people's techniques are for #3, or whether they even do a #3.

Normally, I try to get at the heart of people's motivations / interests and if they understand what being at a startup involves. I also try to see if there's a culture fit.

Are there any questions that you find really effective?
I imagine legacy devices will become an important focus for the Kiks, LiveProfile, Whatsapp, etc. since Apple is leaving them out in the cold.
Care to explain that a bit? I fail to see a direct parallel between farmland tenancy arrangements and Apple's relationship to iOS developers.

Also, that's a mighty powerful rhetorical weapon (going all the way back to African-American slavery) to be dropping in a discussion about some ticked-off software developers.
The other problem is that iMessages will require data connection. When you're roaming abroad, SMS is pretty much the only affordable solution.

Especially as you cannot easily restrict the data connection to only one app, and so you'll easily end up with some interesting surprises in your phone bill.
It sounds to me like a way to "launder" possibly-pirated music. Exchanging mp3s for iCloud songs is analogous to exchanging cash for bank account money.

This will be useable iff the iOS contacts list keeps track of which of your contacts have iOS devices and which don't. That will let the Messages application decide whether to send an iMessages message or an SMS/MMS, without user intervention.

Presumably that could even be automatically updated - the iOS 5 phone can contact an Apple database and register itself as "iMessages-aware", and sending devices can check the recipient phone numbers in that database.

Also, I note that sending contacts and delivery/read receipts are both features that SMS has always had.
The real question is when does dropbox get acquired. Whoever buys it will have a shot against Apple. Whoever doesn't, is in trouble.
It looks Sprint charges around $10 a month for unlimited messaging (the basic plans are $10 cheaper than the basic + unlimited messaging). Though you can also add unlimited messaging to a basic plan for $20... Odd.

There is no requirement for UNIX to "load the entire file before executing," nor does the deletion of files on disk have anything to do with whether or not a file is executable. Under UNIX, any file which has been opened will be accessible until it is closed, regardless of whether or not the file has been deleted (the number of hard links for the inode drops to zero, in UNIX parlance).

Apple’s is about native apps you run on devices. Apple is as committed to native apps — on the desktop, tablet, and handheld — as it has ever been.

Google’s frame is the browser window. Apple’s frame is the screen.

I don't see this conclusion following from his premise. Perhaps there was more in the keynote that he didn't include.

Or maybe I am unimaginative and think installing native apps on all of the devices I use regardless of who owns them, or where they are located, or where my discs are is harder than installing a browser based web app or using an HTML5 website.
The fact that a third party is providing the service doesn't necessarily mean that the process as a whole is legit, in the same way that taking a PDF of a book to FedEx Kinko's to print doesn't make the copy legit, in the same way that buying a Windows upgrade to upgrade your old pirated Windows doesn't make the resulting license legit.

Except that once you use iTunes Match, the resulting audio files are legally licensed, in the same way they would be had you purchased them from iTunes. Here the third party, Apple, is providing that legitimacy as a service ostensibly due to licensing agreements between Apple and the industry players. While actually grabbing the files off of a tracker is still not necessarily legal, the ultimate outcome of the process is that you will have legal copies, thanks to Apple and whatever licensing deals they've made. In other words, everyone wins: I get my music, Apple provides a (hopefully) decent service, and the music industry has found a vector for tapping into those supposed loss in sales.

From the comments of the post:

> Hmmm, let's see, I paid my way to WWDC 2011 with my revenue from google ads on my website content - which are removed when using The Read feature in Safari. That content can also be mailed in full with no ads and no attributive link to friends.

This is actually also an interesting point. Could it be a sneaky way from Apple to push publishers to go Newsstand as their online ads are not working any longer?
> And here’s the real death blow: iMessages will be completely free.

Compared to the cost of my data plan (and the data plan that you'll have to buy to use any iOS5 device), SMS is essentially free. Google Voice provides unlimited messaging for free, all you have to do is download an app. Making iMessage free is not a death blow, and presenting it as such does nothing but imply messaging is a commodity. Not even fax machines are a commodity yet, you have plenty of choices as to which service to use and which machine to buy.

> But it’s not just that iMessages kills SMS because it’s free. It kills it because it’s better.

When I read a straightforward sentence that presents an opinion as fact I expect evidence. In this case the evidence we are given is a link to the Apple website [1] and an assurance that iMessage is "streamlined and simplified."

I've only been following HN for a few months now so this is a serious question, has TechCrunch always been so horrible at journalism?

Is it just me, or has iTunes Match finally made this whole world a slightly better place?

I mean of course, in terms of actually finding a way to monetise content acquired through any means - i.e. I download album over BT, pay itunes match sub, sync lib, then artist gets royalty. It seems like we're finally approaching a sensible business model.
I think you stand a chance to the extent there is enough of a market there to warrant a business in the first place.

To me, it seems that video conferencing has to become literally 100 times more common than it is today before people start using telepresence robots.
