RIAA didn't want music delivered electronically, and iTunes got them over that hump. They could not have thought of that themselves. However, an online book store selling the same products you have for a hundred years is a much easier sell. You aren't harming your existing business, you're extending it from publishing to distribution and sales. That's just vertical integration - quite well-understood as a business technique.

The tricky part is the touchy-feely web aspect (since that they understand publishing and are very close to distribution already). So given the amount of money they stand to lose, I have no doubt they could have made it work. Undercut the prices everyone else has to charge and you create a serious incentive for people to try you out, forgive your mistakes and give you 5 years to slowly figure out how to perfect the model.
I'll be honest, I have already put more time into the first homework assignments for AI, ML and DB than I have ever put into any of the homework assignments for when I actually went to uni. Main reason? It is actually challenging and I have to actually learn the material rather than just coast through. Separate, and mostly selfish reason, I want that certificate!
The challenge Google faces on how to improve the way users retrieve information from the web is actually limited by its own search interface. Google's simple search box interface has successfully trained most users to abstract complex queries into few keywords, and as result, much context are lost as we are searching. In some way, Google Instant is a way to mitigate this problem by previewing results per keywords, but the search experience is still limited to a keyword index, regardless the interface Google wraps around with.

What's interesting moving forward how AI can help search is about how NOT to discard the constraints of human language. In ML, constraints are good, and for search, it can help the indexer to more intelligently quantify the n-grams. End of day, human being still converse in sentences, not keywords.
So, I actually think dlss is making a very valuable point here: the argument that many people are making with relation to hiding point totals, is that if you can see the number of points a post has, it may affect whether you decide to vote at all: you may go "oh, that's already high enough, I won't bother voting".

In essence, people have a mental concept of how high or low they feel posts they are looking at are, and adjust, possibly very subtly, possibly without even realizing it in a way that they would explain if asked, their behavior to cause the post to hit that target, as opposed to showing their true interest with an up/down.

(For a reference on users discussing this effect, and some commentary from PG about having seen this effect on the high end of comment karma scores, see this example thread from another post: http://news.ycombinator.com/item?id=2465271 .)

How peoples' behaviors change is complex. On the one hand, you may see "your side" heavily lower than "the opposition", and decide "ugh, it's pointless". On the other, you may go "ok, that's just not fair", or "help out the team", and make extra certain to vote on that specific poll.

Due to these attitudes, which are pretty much the same things that are driving the changes in behavior with respect to comment voting, you don't get accurate information with public live polls. This really is the same effect, and should be thought of and treated the same.

Now, making the entire poll /permanently/ only visible to the poster would mean, as you say, that the poll becomes meaningless. However, I would say that's a strawman: there are numerous other ways to handle the situation that still make sense.

Example: polls could be private until they "time out", at which point the poll is no longer votable on, and the data becomes public. Frankly, this seems correct, and I'm glad dlss brought it up (although apparently people disagree with the way he worded it or something, which seems silly).

(I also think that this behavior would dovetail very well with "show the comment scores after people can no longer vote on them", which came up elsewhere in the comments for this post: http://news.ycombinator.com/item?id=3122362 .)

Yeah - Groupon seems like it could be a semi-reasonable business, if they can get their customer-acquisition costs under control, but the sky-high valuations (Google's $3 billion and up) are completely ridiculous and buying Groupon's stock is a losing game at this point.
I've got a friend group of a few hundred high schoolers (high schooler myself.) While many complain about changes in Facebook, none of them ever do anything about.

I have a few friends who have decided to leave Facebook, but it's always because they don't like the addiction aspect of it, not any trivial changes Facebook chooses to make.

That said, I really like the new features rolling out. They are definitely an improvement (except for the timeline, that shit's dumb.)

"Would you like Python to disable os.exec* by default just to make websites more secure?"

Yes! Under no circumstances should you ever be spawning new processes from your web application on the fly, ever. You should be using trusted communication to an existing worker thread that is fired up on application start and then never touched except for IPC (think Akka), or trusted communication to an existing process on another machine separate from your web / app server that you can start or stop yourself, separate from the web process.

"Besides, incompetent developers will always find a way to make vulnerable apps using even the most benign features."

Very true; however, you can make it extremely difficult to do so, and you can effectively limit the damage in case of breach. That's what most of the configuration is, from the parent article. Stop someone from being able to write an arbitrary file on the filesystem, by telling them to either store a blob somewhere, or sending data to S3, or whatever, and it will be extremely hard to overwrite existing application code that gets re-interpreted every time it's updated.

"There is also the logistical problem that if the default runtime can't run popular apps such as WordPress, people will simply switch to a broken runtime instead of cleaning up WordPress."

Disagree-- the onus is on Wordpress to keep up with the current version of whatever language they decide upon. When PHP version X disallows re-compilation of scripts on the fly without some sort of notification or server restart, some people and hosts will stay on version X-1, sure, but that's going to be really hard when every distribution starts packaging version X. Wordpress, PHPBB, etc., will need to go through some development pain, but ultimately those packages will wind up being more secure.

The reality is that these kinds of articles shouldn't have to exist. I'm even a little shocked at the Java community, because Red Hat's documentation on "How to Secure JBoss" actually exists, too-- remove jmx-console, remove web-console, and limit access to the http-invoker and jmx-invoker services (and that's it). What Red Hat should be doing is to have a "production" configuration that does all these for you.

>You're also quite mistaken to think that Microsoft ... doesn't care about what nerds think.

We aren't the target market for Windows. Yes, Microsoft wants to get more developers on .NET making Windows apps, and to the extent that it needs them to use Windows they'll make it at least usable for that purpose, but they aren't about to make Windows harder to use for your grandma just to court us. We prefer keyboard shortcuts (which they have) to messy buttons all over the place, but if buttons make the product more usable for their core market then that's what they'll do.

As The Futurist discusses in depth[1], annual world oil consumption has been hovering around 32 billion barrels since about 1982. That means oil consumption, at $100/barrel, is $3.2 trillion, or 5% of nominal world GDP.

My take away from that is technology has made the oil supply a non-issue. And, it will continue not being a problem for the foreseeable future. It is not a hard resource limit.

No, it's not, because Comcast and other ISPs are what's called common carriers in the United States. This means that they are not liable for the content of their customers, such as 4chan.

If you think this is just a legal distinction and not a moral one, consider the company that rents a van to a person who later turns out to be a bank robber. They aren't liable for helping the bank robber get away, because they rent vans to anyone who comes along.

Thanks. This is what I waited for, the rant. You even read my next blog post.

One down. You should not be asking the question, "Why do we need the money?" I answered the question in the original blog post. For skills we lack and don't have 10 years to work on.

Two down. Why would I at this point start telling about my or his possibly epicly stupid ideas. Of course in the case if we actually do fund our first commercial project with crowd funding we will have to tell about the project and why the people should donate to us or invest in us.

I agree that ideas do not count for zip if the execution fails. Startup is a fresh business in phase of development and research for markets. Yes finding scaling business model is nice, but still the product is part of the startup too or you do not have anything to sell.

I know we could go the way of hacking code all night and day until we have something to show. Maybe uglier blocks than Minecraft has with barely no textures.

I was not asking you to give me money now. I was asking if we should go the way of crowd funding or find other ways to generate that cash by part-time working, etc.

You kinda missed the point of the blog post where I mentioned about the 3D sandbox project. Over Design, being over my head, etc.. It's experience which I won't fall into that easily again.

Agreed. The bottom line is I'm not really interested in Marco's opinion on tech products. He may be no more biased than Gruber, but he's rarely as insightful from a consumer perspective. I don't need to hear the umpteenth rant about how inferior Amazon's tablet will be, or how you can't make money in the Android Market. I love my Apple stuff, I just can't get anything out of that kind of cheerleading.

On the other hand, when he talks about actually building stuff or even tangential stuff like the App Store review process, that's where he distinguishes himself and can hold his own against Siracusa and Gruber who are stronger pundits.
I often find it difficult to tell which posts are new when I load the main HN front page, and I end up spending significant time and mental effort re-parsing the same headlines. This problem is compounded by the fact that my session often expires before I finish reading page 2 or 3 and try to go to the next page, making me reload the front page again and work my way back, by which point I have to scan all the headlines again so I don't miss any stories.

It would be nice if either story headlines I haven't been shown yet could be highlighted, or ones that have recently moved onto that results page could be highlighted, so I can tell at a glance which stories I might not have seen yet.
This one should be quite popular among the HN crowd although it's not strictly programming related.

The reason there are so many template languages is because there are so many use cases. Oddly enough, I'm beginning to think that plain old functions are probably the best solution... assuming you have a nicely nestable syntax, like a Lisp or something whitespace sensitive, like CoffeeScript.

ERB and <%= friends %> are great if you have some blob of text and need to sub in some variables.

Markdown is great if you've got a prose document, that want rendered nicely.

You can combine to form erb.md if you need a document with a dynamically filled in field or two.

If you're writing a lot of HTML, then I happen to quite like HAML, since it's a lot less verbose.

However, once you start writing ERB or HAML, or whatever, you're greatly reducing the involvement that designers can have in the process. If you're working on a traditional web site, that's potentially a bad thing. However, if you're making a richer web app, it might actually be a good thing to preclude non-programmers from interfering.

But let's say you have a more traditional web site & have designers on staff who you want to be able to tweak and preview in their browsers. Well, for one thing, it's a lot of work to keep that working. Since even the presence of a single master layout will necessitate some sort of tool to host the rendered page for you... so I'm not sure I understand the benefits of Mustache's HTML-compatibility in that case.

Regarding "power" and "expressiveness" in templates: If you have immutable objects (or at least treat them as such) and you pass data structures, sans methods (such as in a functional language), then you really can't do much harm with those objects alone. It's once you `require 'models'` from your templates, be it explicitly, or implicitly via `template_arg.do_some_query` that bad things start to happen in terms of separation of concerns.

For me, I want to do things like validate that every single `input` element has a valid `id` tag. The fact that I have one syntax for partials and one syntax for elements and another syntax for form fields is confusing to me. Why don't I just make an `element` function and then define an `input` function and then `textbox` function and then a `layout` function and then a `button` function? Consistency and simplicity is beautiful.

Unless I write `require bigscarylibrary` at the top, or pass an unholy (ie. all) ORM object to my views, what could go wrong?

....wow.... I think I'm turning into a curmudgeonly lisper....
When I'm trying to solve reasoning problems with other people, and each of us has a different concept of what constitutes then desired en state, the arguments tend to become very similar to political disagreements, in both the observable interactions and in the subjective way my brain 'feels' during the conversation.

The author of the article believes that political discourse is a process that's intended to "come up with a solution to a problem". This is itself an ideological position: not everyone holds this technocratic viewpoint. If we construe the purpose of the political process as one that's intended to reconcile people who hold competing value systems but who must productively coexist in proximity to each other, then recognizing ideology as the appropriate basis of political discourse is the most rational first step.

Leidenfrost effect:

The stuff of which awesome party tricks are made. I have myself put a very small amount of liquid nitrogen in my mouth and blown it out, although I then heard that the guy who taught me that trick (Jearl Walker) cracked a tooth doing that, so I never tried it again. And for the love of god do not swallow or you will literally kill yourself very painfully -- see footnote 3 of the above Wikipedia article.

I think I'll stick with dipping fingers briefly into LN, which is way less stupid. Done that many times. Do not get it on your clothing, though, because then you can't retreat quickly and the frost is going to bite!

#4 is a viable point, but the problem for Groupon in trying to capitalize on reducing this wastage is that the demand for such services is highly elastic. To a large extent the problem here is a time-of-day issue that Groupon can't particulary assist with. Sure, a restaurant is burning valuable energy outside of lunch and dinner hours, but if such a business owner wants to give a discount during certain hours why use Groupon? That's what 'happy hour' is for, and merchants have a pretty good idea how far they can go with price discrimination without alienating their busy-time customers.

It's a nice math problem, but it misses one key element: Relativity. If most of the universe's human population is expanding away from earth at a speed approaching c, the population growth rate in the earth's frame of reference would slow down -- people might still be breeding at the same rate in their own reference frames, but from the perspective of the earth all the fast-moving people would be living their lives very slowly.

Google captures your intent, Facebook captures your social graph. It's not Google and Facebook does it wrong, they just represent part of us. A service that tries to generalize the whole embodiment of human interaction where they only capture a piece of what we do is not going to work. I think it's human tendency to have multiple identities on the web based on context.
Seems that email is the unifying online id and emphasizes the importance having an email address at a domain that you own and control so that you don't lose it when these social networks disappear or violate your privacy to the point that you need to walk away.

Would it be worthwhile to have a service that managed all of your online identities? You could register multiple avatars/aliases and the service would create email addresses for each of them that could be used to sign up for different networks. Then all of those email notifications, etc. could be forwarded to one confidential email address at a domain that the user owns and registers with the service.
