D'oh. We just received three new MacBook Airs on Monday that we ordered last week. We haven't even deployed them yet. I wonder if Apple offers any ability to ship these back and get the new faster ones.
I've been running Lion for a while and I have the lights under open apps without doing anything special. Does yours not?
The distribution & install story is better w/ a single statically linked exe (imo of course). Not to mention installing node for development and on servers. When everything is in one place it's just so easy.

I think the benefit is huge and don't see how it's a waste of time. Node is linked to specific V8 versions, it makes sense to include it.
Yeah, that's called Stockholm Syndrome... ;p

Why Google+ is 100x More Effective Than Twitter In Generating Comments
Ben Horowitz's actual topic is the challenge of incentivizing management.

His subject is covered very well by one of the best to write about this subject, Charlie Munger (Warren Buffets right hand man and Director of Berkshire Hathaway).

Charlie Munger discusses extensively the challenge of not only incentivizing managers and employees, but demonstrating that it is difficult to even fully understand what really incentivizes them (hint: it's typically different than what their superior thinks it is). He talks about human mis-judgement and its role in distorted intending incentives.

Munger says over 30+ years in business, this is the one area he continues to make judgement mistakes year after year, since this is such a difficult topic to get right. That doesn't mean you can't get it right or that proper incentives don't work however.

Check out the FedEx example in Munger's 1995 speech to Harvard.

Ask HN: Why haven't the social/mobile game companies moved offline?
Been thinking about this for quite a while. Why haven't the social/mobile game companies focused on creating compelling brands and moving them offline into merchandising, tv, books, and possibly even film. They have proven properties and Hollywood is hugely risk adverse why not take advantage of it? Has no one tried this?

Seems like an opportunity.

If you have any kind of Oracle support contract, please put in a ticket. From what I've read, Oracle has adopted 'until paying customers complain enough, we don't even know OS X 10.7 exists' stance on this.

Also, knowing how long it took them to get a working x86 client out, I wouldn't hope to use 10.7 for Oracle-related development at least till next year.

Author uses the terms government surveillance and tax collection as if they are inherently bad things.

There are some things I want the government to watch, at both a local and federal level. And keep in mind Oliver Wendell Holmes's Jr's adage about taxes: they help foot the bill for civilization.

As for bureaucracy: it's a burden, but the alternative in many societies is systematic corruption. The author writes:

Less obviously, but at least as importantly, we need to eliminate the insane patchwork of regulations that keep folks from legally cutting hair for money in a kitchen, or legally making a few bucks every now and then taxiing people around town in a 1988 Ford Escort.

If it's an insane patchwork, perhaps. But if it's a sensible patchwork that helps keep schools funded and slows society for a dispiriting race to the bottom, why the hell would we want to do this?

Einstein's relativity is undoubtedly correct in its basic tenets. But there are some finer points which were or are still up for debate.

Frame dragging is one example. There were several theories offering slightly different predictions in that field (that broke down to perfect identity for real-life situations), Einstein's GR being just one of them.

So, in physics it's like this: trust, but verify.
I have a 13" MBA of the previous (Core2) generation - very happy with it. I bike commute so the small size & weight were important, and the OSX development environment for Ruby is fairly well evolved. Jeff Atwood has already flogged the benefits of SSD, and I'm a big fan as well - but whatever size suits your data makes sense, I wouldn't over-buy just for the i7 option. The difference between i5 and i7 usually only shows up in very specific workloads that take advantage of the i7's hyperthreading or clock bump. For general development work you won't see a difference, although both i5 and i7 are substantially faster than the Core2.

Existence precedes essence

I came to similar conclusions of this author after reading Camus' The Stranger (and many other Existential books thereafter) in high school.

There's no meaning to life other than what you make of it. This author finds meaning in building things, seeing things grow. Other people find meaning to their lives by shining shoes and are just as happy. Or at least they find contentment in what they do, which in many ways is better.
The headline could've been better, no question.

Fonts and interface chrome always seem to take up a tiny bit more space on OS X. Not usually an issue but I'd take it into account if, on Windows, a given res is barely usable.

I have a 13-inch air; the pixels are tiny. If you try 1440x900 on a large monitor, bear in mind smaller fonts may not be using once you shrink down to laptop size.

Apple stores seem pretty liberal about machine use (notwithstanding the guy being prosecuted for installing webcam upload software on a store's machines..) - maybe you could download Mac Eclipse to a USB key and try it out on a machine?
While you are here....Why only a single boot drive? It seems like an obvious failure point, and at only $40 per drive I would think soft raid 1 would be no-brainer for reliability.

At first glance, I thought this was a message by Ian Goldberg, one of the two designers of OTR, but of course it's Ian Grigg.

His points are basically correct but I think a little overblown.

The point of OTR is not to provide you with real-world deniability, but simply to not remove it in one particular way, by not providing additional evidence of the authenticity of a logged communication, beyond what would be available if the communication were in plain text.
iOS 4 SDK came with a version of Xcode 3, and iOS 5 comes with its own version of Xcode, neither 4.0 nor 4.1 — so it's not inherently tied to the normal Mac Xcode at all. iOS might have had something do to with the early release of Xcode 4, but releasing it for general consumption was a different matter. At any rate, this is not a regressive move for Apple.

Echoing the sentiments of the other 11" owners, I love my 11" MBA. It's not perfect but it's close enough for the time being.

I just bought a brand new 11" with a bigger SSD and the i7 and the only thing I wish was different was the amount of RAM. If it had 8GB RAM, then it would easily be the best computer I've ever owned.

Well, this again is a very hacker-centric perspective. Even if it's truly important that someone be able to surreptitiously copy all of JSTOR once in a while for the sake of innovation, who is in a position to let him off based on that?

Plus, putting everything else aside and evaluating him as a hacker, he doesn't come out looking too good. If he'd scraped all of JSTOR without getting caught, it would make a better story. As it is, he attracted a lot of attention, and the report of how he was caught has an air of inevitability to it. JSTOR called up MIT, MIT was looking for him, and he gave them a lot of time to find him.
Full Tilt Poker and Poker Stars were breaking the law. That's not what Betable is proposing. Had those two companies stayed outside of the US like Betfair and many other multi-billion dollar real-money gambling and betting companies do (it's a big world out there), then they would have been fine.
"Ian G" correctly recognizes that OTR doesn't provide mathematical reliability, but rather just prevents mathematical confirmation. The issue here (seems to be) that he incorrectly thinks that it is said to do anything else. "Ian Goldberg" (an apparent different person) points this out well here: http://lists.randombit.net/pipermail/cryptography/2011-July/...

There is also some mumbo jumbo about what math should or should not attempt to do. If I'm reading this correctly, it seems like Ian G is also opposed to any system that could do what he thinks OTR allegedly does. Seems like just another opinion to me, not really worthy of much analysis.

xcode is a tool, and has near the same potential to make you a millionaire that a pencil does.

That's true. You're not encapsulated from JS, so you have to be aware of JS issues like null-undefined-false-0 and all the rest of them. So it feels like you're writing in two languages at once. On the other hand, that has some benefits too.
For me, Xcode 4.1 removed gcc-4.0 (needed by brew for example). If you had Xcode 3.x it's still in /Developer-old, and can be re-added with ln -s /Developer-old/usr/bin/gcc-4.0 /usr/bin/gcc-4.0.
If they aren't custom configured I think it's easy to send them back for new ones. I thought Apple typically let you exchange without fees if you bought within 30 days of a refresh.
> It would be great if business and labor laws were streamlined to make this as easy as possible, but its disruptive to larger corporations and current stakeholders ...

Certainly that's one part of the phenomenon. But keep in mind that regulations exist also because there are always people who want to take in as much money as possible while doing as little work as possible, leaving others---possibly meaning the public---to pick up the pieces when things go wrong.

(A recent example: Wall Street investment bankers, playing the heads-we-win, tails-the-public-loses game with bank bailouts. A recurring example: Polluters.)
This keeps coming up every now and then. What's the difference between Xcode and iTunes that lets them give iTunes updates for free?
I suggested local storage only for the case where a new user (not logged in) has added some tasks and then decides to sign up. The tasks in local storage would then be added to the user once it is created. The local storage acts as a temporary storage location while the user is created. Having this work across platforms is not necessary.

There are a few reasons but they are all related to the quarterly numbers. Whether it's salespeople who get a bonus or the board pushing for a quarterly revenue number, sales will make the biggest concessions at the end of the quarter to try to close the deal. Customers are aware of this and so they push closing out to the end to take advantage of it.

Ways around this might be to look at some kind of rolling 3-month average when examining revenues/sales or comparing sales people to each other (although depending on the sales volume this might suck statistically). You could also do sales bonuses as a combination of numbers + manual review. Maybe eliminate bonuses altogether and go straight commission so that the salespeople's incentive is to close the biggest deal irregardless of when. This of course is predicated on the board not pushing for big quarterly numbers; if that is the case then they are possibly the ones being the "bad managers" (minus extenuating circumstances like shopping around for a buyout).

The Thunderbolt display is somewhat different - I believe HMRC count displays with digital inputs as 'video displays' instead of 'monitors' and subsequently levy a 14% customs duty:

FWIW, Homebrew only needs gcc 4.0 for a select few formula. The vast majority of them build with more modern compilers (gcc 4.2, llvm-gcc, and clang are supported; and I use a non-Apple gcc 4.6 to compile things occasionally).
Are you saying that the gcc no longer ships with Xcode, or that it, for some reason, moved the gcc binary to a different directory (or both)?

If the gcc no longer comes with Xcode, how might one get gcc for OSX Lion?
iOS developer here. 3.0->4.0 is the biggest jump in product history. 4.1 is just a bugfix / Lion support / couple of new widgets release.

It doesn't appear (warning: no release notes yet) that 4.1 runs on SL or that 4.0 runs on Lion, so run the version appropriate to your OS.
This is a really interesting relationship triangle happening at the moment.

On the one hand, you have Apple, a "traditional" hardware/software company, whose aim is to move as many devices out the door (IIRC, hardware is their primary revenue source with the largest margins). They do this by making awesomely polished software that they lock to their devices.

On another hand, you have Google and Facebook, which are information companies. Their primary goal is the collection and organization of data. Google does this through many fields (but for the sake of this discussion, I'll focus primarily on Android and Google+). Facebook does it through "social."

What I find interesting first is the announcement that Apple chose Twitter for iOS 5. From the post on betanews (http://www.betanews.com/joewilcox/article/Why-did-Apple-choo...), Apple chose twitter because it wants information to flow freely between its devices (facilitating their ultimate goal of selling more devices).

But more so, Apple is now in a position to really hurt Facebook since Google+ came along. Since Google's goal is the free flow of information, we are continuing to see iOS Google apps, despite the popularity of Android and the seemingly competitive nature of Android vs. iPhone/iPad. But Apple benefits from Facebook's demise and Google+'s openness, and Google benefits from this because they continue to collect more information. Facebook loses in this case since they locked themselves into a corner that they can't get out of anymore. I think this was a well played strategic alliance on the part of Google and Apple.
My brother likes to say that America is an adolescent, while Europe is the adult. According to the article, it sounds like the America is growing up and it's manifesting as a desire for job autonomy in the labor market.

However, the author misses an important link between job autonomy and the question posed, "What is the single best thing Washington can do to jumpstart job creation?"...

The fundamental reason that "job autonomy" is more viable today, is thanks to the internet and free-flowing information. If there is one thing the government could do to jumpstart job creation, it would be to improve the regulatory structure surrounding the internet, bust the monopolies that are gouging us for awful service and give incentives for startup ISP's to take their place.
We would like to, we just haven't had time to get it done yet. It runs internally, but is lacking an installer and a GUI, and we would need to prioritize and choose one or more Linux distributions to launch with. Ubuntu is an obvious choice (we focus more on desktop backup than on servers). But some people also ask for CentOS and a few others. It bums me out the Linux community has not solved binary compatibility anywhere NEAR the same level that Microsoft or Apple has, and few in the Linux community seem interested in solving this issue which massively, MASSIVELY hinders development and deployment, but that is a side tangent...

Explanation about the "GUI" comment above -> the Backblaze backup client was simultaneously written from the ground up compiling on Mac OS, Windows, and Linux. The same tree and the same source compiles on all three on EVERY SVN CHECKIN. There is one exception, which is the GUI is an extremely simple stand alone process entirely natively written to match the host OS. On Mac OS it is in Objective C in the beautiful Apple GUI layout editor, on Windows we use Visual Studio and C++ and Win32. The firm rule is these GUIs are ONLY allowed to edit one or two simple XML files, and all the real encryption, compression, transmission is done by other cross platform processes. On Linux we configure the XML file with "vi". :-) The X-Windows GUI has not even been started.

I believe it would do so automatically only when it can prove that the bound will not be violated. That wouldnt be very often in a program written in an imperative style.

Lest it be mistaken for a swipe at imperative style, functional languages don't have it much easier either. I think the problem is that for the most part, array use patterns are not very amenable to this kind of analysis. So even in functional languages you have to explicitly ask the runtime or the compiler to avoid bound-checks.

If I remember correctly, there were a few languages designed to handle this case, i.e. use compile time type-checking to ensure that all the arrays are of the right shape and that none are accessed un-safely. Fish I think is what it was called. Dont know what happened to it or the idea. Seemed pretty handy to have. I think the first place to check now would be SAC (single assignment C). But I have digressed far from the topic of this thread !

I'd say any competitor worth worrying about would be able to build an equivalent system from scratch pretty easily, so I don't think they're risking that much. Convincing users that you'll be trustworthy, secure and around in 5-10 years is a much greater hurdle.

On the other hand, I read this article and I read their last one, when it too shot to the top of HN. Geeks go nuts for hardware porn, and are a great audience to sell these kinds of services to. So the marketing benefits are probably quite substantial.
Their tasks:

1. Click on the things that draw your attention the most.

2. Click on the elements you like on this page.

3. Mark the things that you think we should improve.

These are the wrong tasks to be asking users to complete. A real user task on TechCrunch would be "Find and read an article that seems interesting to you" or "Find and read the 3 most recent articles about FourSquare" and so on.

This is basically a focus group for "do you like this redesign", not a task-based usability test.

Studies [0] have shown that, in essence, money and happiness correlate up to about $75k/year for a U.S. family of four. Above that level, money might open up options, but it doesn't seem to increase happiness as a whole. As others have noted, you can have a lot of financial freedom well below the million dollar mark, or be financially burdened above it.

It should come as no surprise that some people have come to that realization, and decided to simply meet the threshold, life a financially stable lifestyle at that level, and invest the rest of their energy in enjoying life.
