I'm surprised they don't cache output on logged-in pages as well, using ESI or some kind of client-side replacement. There's not that much personalization going on. Most page content is the same between users.

My original Aluminum Unibody 13" macbook has been dropped 6ft onto a hardwood floor, and banged multiple times against aluminum braces. Has a few dings, but still going strong.
It's also about how power behaves when threatened (which I think does describe Android's relationship to Apple).
Anything like this in Clojure?
His 3rd point, regarding color, is to me one of the most compelling reasons Apple maintains such a large market share of portable products over time. No one likes to own the exact same thing everyone else has and so by using color to differentiate, consumers can still feel unique when purchasing mass-produced items.

Has any other company used color in such a way? (the only example that comes to my mind is the original Pokemon games)
There are lots of very interesting things in this post - one of the most interesting long term changes I see is that Google are now admitting that you can lobby for algorithm changes.

I can imagine in another 12 months there will be vocal lobby groups to get Google to change parts of their algorithm for certain types of sites. This feels like the start of Google coming out of their shell and admitting that they listen to communities like HN and will respond with large scale algorithm updates.

I'd also dearly dearly love to know what this breakthrough was:

"Amit Singhal: Well, we named it internally after an engineer, and his name is Panda. So internally we called a big Panda. He was one of the key guys. He basically came up with the breakthrough a few months back that made it possible."
I often wonder whether there's anything that Apple could do that might make the faithful admit they've done something wrong. Once again, this is one of those times.

Excellent.

We're building a marketplace, so if that isn't clear I definitely dropped the ball in communications on the first few pages. (It's more clear when there are active listings, but we don't have any of those yet...)

Which text specifically? The main body text or some of the lighter grey text? I understand there are some issues with some of the lighter grey text and I'm working out a way to keep the contrast while keeping within our design constraints (When integrated with a vBulletin forum the site takes on a user-specified stylesheet).
Since R isn't included in RStudio, merely acting as an interface with the R session, I doubt this is an issue at all.
can't execute yet..... it's only a matter of time. Apple has to keep moving forward.....
Your last point is exactly what needs to happen. Let me just add that on top of cultural and societal components, there's a massive system (the current school system) that would have to be redesigned as well. The amount of checks and balances to keep that system in place is enormous. I'm convinced that forcing it out is the only way to change it. Khan has definitely provided a good beginning, it just isn't there yet.

Success of a business depends on how you execute it. Paul Graham has once said if your idea is a good one, you'll have not just one competitor but hundreds of them. Don't give up with just one adversary. Plus i just tweeted and facebook shared your website for my support to your marketing journey.
This works very well IME. There is a potential issue however, in that if you are too prepared, you become married to your vision, even when someone else points out fatal flaws. Essentially you can lose flexibility.

This may or may not be what is desire, but I have seen projects go down in flames because of over-prep. The goal is to find a nice balance.
This made my day, it's giving a personnality to the system i use the most. It is so tired of crawling the web to find me results that it makes typo... it is very human. And the quicktime stuff shows its very lazyness. When computer will make mistakes and have emotions they will be more understood by everybody. I read that somewhere in an old book.
I think the problem is not that the list is too long as much as that it jumps across categories, making it look like you were stretching to make it as long as it is. Some point out cool stuff you can do with Highrise, some are actual FAQ type questions on platforms and whatnot, and some are just hypothetical use cases.

If you cut some of the latter and reform the rest into more general questions I think it could be really effective. (e.g. "Can I see a list of all the CEOs I know in San Francisco?", "Can I see a list of everyone I know in the 312 area code?" >> "Can I view groups of clients by contact info?" "Can I view lists of contacts with stacked filters")

[edit:] Alternatively, you could make the list predominantly use cases.

Yes, it is about time to allow some wiggle room. I am glad that grammar and spelling correction became a meme. At one point, it looked like the web was going to deteriorate into all lol speak. It was also leaking into offline writing, as well. Ebb and flow has a great end result, but the process is often painful and/or annoying.
This is a great service, and if I was in a position where I had to deal with phone trees regularily for my job, then I'd even be willing to pay something for it.

One minor gripe -- at least in Chrome, if you type something in ("Verizon") and hit enter without selecting any of the auto-complete options presented, you just get a generic "whoops, something went wrong". Ideally, just pop the user through a screen that lets them select from a list of possible matches.

I'd make a snarky comment about how the site doesn't render properly in IE 5.5, but I think I'm about 2 years late on that trolly.

You are not reading it correctly. I'm saying that there were 47 stories on this topic, of which 31 were by women. Techmeme featured 6 stories on this topic, of which only 1 was by women. Whether or not a view was written by a man strongly is strongly correlated with whether or not Techmeme features it.
I personally would be quite worried about it being used for prank calls. At the click of a couple buttons anyone can create a very awkward conversation between AT&T and a random stranger (or a friend).
A classic copywriting trick for a long list of bullet points like this one is to make every other one bold. This greatly increases readability and conversions.
It's also interesting how they admit that the results can be gamed if you know what the changes they've made are. While that's most likely always been the case with Google's algorithm (any search algorithm, really), it's interesting that they're publicly saying it.
I got the list by watching twitter, following links, googling, binging. It probably isn't comprehensive but is a superset of the other lists.
Case in point: I'm pretty sure that using "mis-grammar" as a verb (or at all) is not the officially approved way of saying what you wanted to say, but it got the point across just fine.
I do believe Facebook has a tad bit more users than Apple products. I also get then feeling, just walking around the area, that people spend more time on Facebook than Google.
Indeed. My mind races:

something like assigning super-distinctive words prime numbers and multiplying them in a paragraph, and doing a lookup on it to see if that combination of super-distinctive words appears elsewhere.

The limits of our knowledge of biological systems are pretty significant. At this point a lot of our medicines are comparable to newbie programmers trawling google for random code snippets that they then copy and paste into their source, hit compile, at hope it works. We're still just bumbling around and in many cases engineering by luck. That can still pay off but it's important to recognize how horribly limited such a technique is.

I need this for conference calls. Normally, I dial in at the time the meeting is supposed to start, but nobody else comes for ten minutes. This means I have to sit around and listen to the "nobody has joined yet" music, which sucks.

A system where the system calls you when everyone has indicated availability would be much nicer. No wasted time dialing in.

And BTW, these conference call services typically cost something like 30 cents a minute times the number of participants. So if your product eliminated 30 wasted seconds of airtime per employee per day, you would save a company like mine 12 million dollars a year.

I was surprised to see Jobs hit Samsung with the repudiated 'quite small' quote, but at the same time Samsung hasn't exactly been eager to release their sell-through numbers. They haven't been shy about claiming their tablets are big sellers, though. Where is the condemnation of their claims that the Tab represented a third of tablet sales, when it's obvious from the near-total absence of them in the real world that they're nowhere near those numbers?

If Samsung is bothered by Apple's claims, they're easy to refute - just release the numbers.
If you know what you're doing, then you'll actually be the first to dismember your original vision. Indeed, a principle value of this approach is that when you do hit the inevitable need for changes, you're already well acquainted with how all the pieces fit together. This allows you evaluate options by considering not only their obvious pluses and minuses, but also by anticipating the more hidden costs and benefits of any given alteration.

This (I believe) is what Eisenhower meant when he said "plans are useless, but planning is invaluable."

Ask HN: Ideas are cheap link?
Hey HN,

I'm trying to help some business students and am looking for a specific article I saw surface a few times. I'm in a time pinch, and searchyc and Google are failing me.

The article in question is around ideas are cheap, or ideas are commodities. There was a long list of existing ideas that single person came up with, and the point being the value is in the execution. It's not the Inc article not PG's /ideas.html article, but a list of ideas.

If you vaguely know what I'm talking about, I'd be happy to help clarify it. If you can share that link, I'd be very grateful.

Thanks, and sorry for the uninteresting post.

Edit 1: Thank you! I thought this would go past /newest and die with the spam. I appreciate the links, but the post/article I'm looking for was essentially "see how invaluable an idea is? I'll give you a list of x number of things that I think would be an interesting business." The article then goes on to provide a list of ideas.

Yeah, because calling out someone's bullshit is now "abusive behaviour".

Listen, people here aren't retarded - they don't need someone to try and explain why Jobs lied. He lied because he can make himself and Apple look better if he told the truth. It's the same reason most other people lie and it's so transparent a toddler can see through it.

No one's gonna stop you from posting low quality Apple fluff, but don't expect not to get called out on it.
Is it common not to be able to write a blog?
Dear fellow hackers,

I'm 20 years old, and a pretty inexperienced hacker in terms of finished projects, but I've been coding for a couple of years now, and had been reading source code since I was 12.

I also love writing, but continuously struggle to come up with topics to regularly write about. It always feels like everything has been documented on the web, and I don't think I have any insights to any field that would deeply interest intelligent readers. I make a blog with a single draft and shut it down; it happens every few months.

Anybody having the same feelings? Suggestions, please?
I concur, in principle, but in practice I have both seen and experienced what happens when one gets too involved. It can be quite the challenge to accept that a good idea is coming from some jerk who didn't even bother thinking about it before the meeting. Or worse, the fatal flaw gets pointed out by someone who has spent the last half hour trying to torpedo the thing by hoping to get lucky with random comments.

On the other hand, there is quite the satisfaction that comes from seeing an opponents face when you show up so well prepared -- the moment of victory is sweet :)

T is a linear transform/map or (it is the same thing!) a homomorphism, or a matrix: an application between 2 vector spaces that preserves vector addition and scalar multiplication (i.e. f(x+y) = f(x)+f(y), f(a.x) = a.f(x)).

T : V -> W is the signature of this homomorphism, whereas ker(T) = {v \in V | T.v = 0} means "ker of T is the set of vectors v in the vector space V such that T applied to v is the neutral element of W". The neutral element is noted 0 because, in a vector space, it is such that v + neutral_element = v. So neutral_element is the null vector.

I learned algebra kernels in my first year of college, so I assumed wrongly. But that's not the point: I was not thinking about explaining what a kernel is but instead (higher level) trying to group what seemed to be scattered definitions into explaining why we call "kernel machines" this (and why a kernel trick involves a kernel).

Now, I'm thinking about explaining (with pictures) what an algebra kernel is...

I was a little jarred that he explicitly mentioned rape. Don't get me wrong, nothing is off-limits for a joke, provided it is funny enough, but this joke is just as funny without the last clause. Including it is just redundant, not to mention it pulls the punchline slightly. To me it reads like he's trying to be offensive.

I guess this version of the punchline could hit through a language barrier though?
The problem with your comment is that it begs for a response in kind. The tone on the thread changes, from tendentious to outright hostile. Users click into threads and see high-ranked comments with that tone. They write their own comments like that. Oh, look. Now we're Reddit.

That's interesting. I was thinking last night whether it would benefit HN to be structured more like Quora. Naturally in some discussions I would love to see it, however in others perhaps not. HN places focus on good comments more than anything, while Quora on good answers with a bit less emphasis on commenting. A blend somehow I believe to be the future.
All this talk about "outsourcing our memory to machines" sounds like a load of zero-sum thinking. It's not that we're shrinking our biological memories and pushing our memories into machines; instead, we're using the internet as another level of the memory hierarchy, allowing us to work with more information, faster. Why would using the web make it harder for us to store information in our biological memory? If anything, it lets us choose to memorize just the important parts, because we can look up trivial details easily.

To use a computer analogy, you could think of our short-term memory as CPU cache, our long-term memory as DRAM, and books as floppy disks. The internet, then, can be compared to a hard drive: much faster than floppies, with a lot more capacity per dollar. (I wonder what would correspond to solid state drives in this analogy. If you can figure out what it is, you can probably make a lot of money by building it. If Google doesn't beat you to it.)

A meta-criticism I have of this article is that it doesn't talk about actually measuring the supposed hurtful effects of the internet on creativity. I know this is a hard thing to measure objectively, but there's got to be some way to elevate the discussion above the level of bluster-laden hand-waving about the Scary New Thing. What testable predictions does the article's thesis make? If anybody has ideas here, I'd love to hear them.

True - the study does not eliminate the possibility of a discontinuity at 0 colonization. (I.e., no colonization is better than some colonization, but once you have some, more is better.) Do you believe this to be present? If so, could you explain why?

(I'll generally ignore the "I hate descendents of people distantly related to colonisers sooo much" part of your post, with one exception. The other measure of "good modern outcomes" is dead babies. Is "fewer dead babies" also a synthetic measurement created by colonizers?)
From the article:

Can you use their tool without submitting my UDID? If not, can I opt out (other than by not using the app)? I like your app, but that is essentially a tracking supercookie.

Actually if I am not mistaken, it is against the app store TOS to submit a UDID to a third party without the user's consent. Apps that use Flurry's agent in particular took heat from Apple for this. This is basically spyware.
