Usually it's from a master. But the quality loss due to broadcast compression is great enough that the difference between a master and Blu-ray source would hardly be visible.

HDTV is usually better than a DVD though if it's a premium channel from a good provider.
I don't see how digg is similar to kuro5hin or delicious - kuro5hin was about essays, delicious was primarily about serving personal needs (saving bookmarks) first. They seem very different to me. Digg also inspired a bunch of similar sites using the same mechanism (like Reddit and Hacker News) which suggests that digg had something genuinely new to offer.
A Twitter Engineer's Epic Diss of 'Disgusting' San Francisco
> Likewise, erlang's lightweight processes are exactly the same -- threads. The fact that they can be modeled to arbitrary numbers of operating system threads is irrelevant to the nature of the model -- one in which execution of a thread can proceed independently of others, implemented via context switching of execution state across those threads, able to access shared state.

From Wikipedia:

> The Erlang virtual machine has what might be called 'green processes' - they are like operating system processes (they do not share state like threads do) but are implemented within the Erlang Run Time System (erts). These are sometimes (erroneously) cited as 'green threads'.

http://en.wikipedia.org/wiki/Green_threads

Going back to Ruby, sure, threads might be theoretically better than processes, but in practical terms, other things are the real bottleneck, so it ends up not really mattering that much.
Ruby isn't the issue here - most of the hardware spend (tiny as it is) went toward master and slave databases. Our database isn't huge, but it isn't small either. The working set doesn't fit in 32 GB of memory - lots of memory and fast disks are critical (even with caching and all that) and that takes 2 non-cheap servers.

7 machines is getting into part-time sysadmin territory.

My estimate of peak load was somewhat generous in averaging it across only 5 hours -- could you elaborate on the actual peak load?

I'm surprised that something that's orders of magnitude slower than the alternatives isn't at least part of the issue, given the amount of front-end stack required, hired employees, and 3 6-core (6?) 40 GB front-end webservers required for 10 million hits/day.

I worked on Java web apps for 8 years before starting Ravelry and I definitely don't regret choosing Ruby for this project :) Did I have to buy 1 more server than I would have had to with Java? Yeah, I think so. ...but the trade-off was definitely worth it.

The JVM truly doesn't require Java, Spring, or J2EE, and it's an incredibly impressive piece of technology to just discard.

It's a bet either way and anecdotes are anecdotes, but Netflix has lots of data and personally this is how I behave.

I've dropped TV entirely for Hulu. What I can't get on Hulu I order from iTunes.

If every movie on Netflix were streaming, I'd watch it that way, even at a lower quality.

So, YMMV, maybe you're 100% the opposite and/or you know lots of people who care about 780p, 10455p, and whatever else. But I don't think I'm from Pluto, either.

From a strategic perspective I think he's right in the limit. Bandwidth is going to infinity. If consumers prefer timeliness to quality they'll put up with lower quality and wait for bandwidth to improve.

The end game is the same: high-res everything, instantly.
> The Erlang virtual machine has what might be called 'green processes' - they are like operating system processes (they do not share state like threads do) but are implemented within the Erlang Run Time System (erts). These are sometimes (erroneously) cited as 'green threads'.

Erlang processes' implementations share internal mutable state, despite the fact that the inter-process messaging API available via the runtime does not expose this. They have to -- internal cooperative context switching can't be implemented without shared mutable state.

They're threads.

Going back to Ruby, sure, threads might be theoretically better than processes, but in practical terms, other things are the real bottleneck, so it ends up not really mattering that much.

I'm not sure I follow. Is this something like "ruby is really, really slow, so no need to worry about concurrency" ?
RIS/PACS Technology to Improve Clinical Care

I know all this but it's the fact that I have to go through all this trouble to be able to use something that I paid good money for.
Yes, this is a really important point. A lot of the "OMG git is so cool" early adopters seemed to go off on how great forking things is without making this critical distinction between a 'code' fork' and a 'project' fork. The first is simply a technical thing - the latter is a human thing.

Indiscriminately creating random project forks without contributing back is "bad open source citizenship".

A lot of the "strings" seem expansions of others or superfluous. For example, it lists "Physicist, philosopher, author, mathematician" for Penrose. I'm not so sure that theoretical physics and maths are different enough to qualify you as a polymath, and "author" falls out of being a good physicist; he's not exactly writing fiction on the side.
And I'm trying to figure out some way in which I will be down voted for this.
"Like everyone else in the world, I already have a well-established workflow for managing usernames and passwords."

Is this true? I was under the impression that password managers are very techie-oriented. Your average user uses "password" or an equally naive variation thereof, with a handful of username/password combinations. I don't think OpenID is intended solely for techie sites.

I'd use pointless style more: row = (!!)

The function valid has a lot of repetition, maybe the repeating part can be abstracted of?

Instead of length possible > 0, you can use not $ null possible. This is faster, since it doesn't go through the whole list.

Instead of pattern matching on Maybe (tile), you can use Prelude's maybe.
I see the potential for a lawsuit here. What if someone comes up with the obvious idea of trying to play a tune? The leaping around would most likely result in serious injury.

Riak - web-shaped data storage system
I can see his motivation for this -- I was thinking of this exact idea today. There are simply so many rudimentary questions new entrepreneurs ask that can be easily answered. Two examples that I've recently sought answers for are "how do I negotiate for domain names," and "how do I set up a credit card payments system on my website." These are two of many, many more.

I've been a reader of HN since the beginning and have found it an invaluable question/answer database. All my questions have likely been answered before (I've found some really obscure stuff!).

Most queries can be answered by searchyc.com or a Google search prepended with "site:news.ycombinator.com." It'd be nice to have unfiltered access to entrepreneurial questions, ranging from the broad to the very obscure.

StackOverflow works beautifully, IMO, and I hope this blossoms into an excellent complement to HN.
What I hope: the comments on this article don't become yet another conference of blowhards and apologists.

The frequency at which I've seen comments paraphrased as "So you hate your work; welcome to life, now shut up and get back to it," is disheartening. I am surprised the number of people, even on HN, who see this mutual antagonism as not just a self-fulfilling prophecy, but one that can and will sustain itself indefinitely.

I honestly don't think it will. In fact, I think it already failed some time ago, and we are feeling the effects of it right now.

The article brings up the number of people who are, or at least feel that they are, stagnating at their current jobs. It also draws the connection between the feeling stagnation and a reduction in productivity and competitiveness. But stagnation isn't typically a temporally local phenomenon; a person does not usually become redundant or stagnant overnight. However, their realization that they are redundant or stagnating can occur overnight, often after ignoring the warning signs for as long as they consciously can.

But productivity isn't just affected by the feeling of stagnation and vulnerability; it is affected by the actual stagnation that an expectation of mutual loyalty causes. The worker can become lazy with the expectation that the employer will keep them on anyway, provided they aren't completely incompetent. This is a considerable threat if the worker doesn't give a damn about their work past the paycheck; what incentive do they have to be anything but as lazy as possible. They were clinging on to their jobs before, but the recession made them acutely aware that they were doing so and how tenuous their grip has now become.

This apathy also negatively affects productivity and competitiveness. But no one notices, because it is business as usual; at least it was. But now employers have started to notice, but they are solving the wrong problem; they assume the problem is one of insufficient data or insufficient supervision. They never assume that one or more of their underlying assumptions about their workforce, and what makes them most effective, might not be true and might never have been true.

I hope that people wake up to the larger lesson this turmoil is wanting to teach all of us. Unproductive people working in what are effectively sinecures are not a sustainable way to run an economy based on the production and distribution of wealth. Eventually, someone will ask where all this wealth is, and won't abide a waffling, noncommittal answer.
If there's any one major flaw in this article's argument, it's in its attempt to establish an hierarchy of informational importance.

While it's pretty easy to say that the study of the functionings of neurological chemistry is by far more important than what body part Britney Spears has inadvertently shown off to the public, everything in between is a shifting gradient of gray and dark gray.

While arguments can be made that, on the grand scale of things, the intrigues of corporations and their stock prices are more important than whether or not that new DIY tabletop fabricator blueprint's worth the hype, I think quite a few of us here would immediately flock to the latter link FIRST... and would be quite interested to know what components it calls for, and where to get 'em.

The answer is in more efficiently targeting advertisements, not in dismissing its utilization altogether.
I doubt it - he seems to have an abundance of energy and Mahalo is probably run well day-to-day by the people he has around him.
FWIW , no one is saying you are wrong. If we thought that, your post would not be on the front page.

Simply put, you said it yourself: "I am bringing a complete idea and some code to the table".

The code may be worth something.

The idea, not so much[].

Salesman or marketer? A lot of technical folk confuse the two. I think he can close deals, for sure, but really he is a talented marketer.

A lot of really good sales people don't make it obvious they are selling, Jason seems to make it a bit obvious in an un-ashamed way (which make me think he is more interested in getting the word out then pushing things on people).

His enthusiasm is infectious though, its really cool assuming he is sincere (and I am pretty sure he is).
One more addition
* Von Neumann - Mathematician, Economist,Game Theorist, Computer Scientist.
Although it's clear each describes their service differently, setting aside their public relations it appears to me the basic service they offer is basically the same: they make it easy to setup community sites where people can post things, vote on things and accumulate karma. Whether those things are news articles, answers to questions or other things (like reviews of silly iphone applications e.g http://iphone.lockergnome.com/ ) makes little difference technically.

What I'd really like to know, ideally from someone who has worked with both, is if there are any particular features one or the other offers that actually do matter.

Or perhaps this is an example of where developing good PR is more important than focusing on features?
"Business speak" as a term doesn't mean the useful business speak of increasing revenues, lowering costs, serving customers, pressuring suppliers, etc. It means things like "leveraging data," "strategic synergies," etc.
this leads to a "who do you like/dislike openid"... but i think it is irrelevant. it is more "why such application force you on this ?"

this application is not about promoting openid, it is about ask/answering question on startup. So the identification and authentication should remain mainstream, not to uselessly disturb the user.

openid is an option, username/password, google, facebook and co provides others
How is paying to go to a conference where you can network (or present, if you are lucky) with the whos-who of tech, versus for the opportunity to pitch to 1 single angel group/firm ? Not even remotely connected - absurd to even think so.

On top of that the amounts of money seem to differ by at least an order of magnitude.
Thank you. In the scenario I envisage, the technical lead becomes the CEO assuming I do not travel to California.

I am looking for a high calibre team and feel that I and the idea warrants one.

I am sacrificing my control and equity by recruiting on HN in this manner, and I agree with you about the 'tech guy' often receiving the raw deal at times, and have actually worked as that person numerous times -- the sub-ordinate in 3 non-VC backed startups already, including a ticketing startup.

I am more than happy to grant more equity to other cofounders than myself: it would depend on how much input they want from me.

I have also been a drummer and know what it's like for musicians and managers to organize gigs and tours.
What are the differences, advantages, dis-advantages between Riak and CouchDB? I haven't found a comprehensive comparison till date.

I'm not bringing code to the table (the dev didn't start, but we worked the idea, requirements and functionality through). I am bringing myself to the table. ;) There's only a certain length to which I can sell myself and my idea in a public way like this without making myself look desperate, which I'm not, or lowering its value due to exposure.

The main message I can give is: if what I am saying and want to do resonates with you, Try Me.

Also, I have to be careful of people who just want to hear me out but then not do anything afterward.

My thoughts exactly. Taking this criteria, thousands of people can be listed, author just lists people he heard of. Not like any of them are a new Leo.

But yes, even in specialization age there are talented people who are successful in more than one discipline. There are many thousands of them. But "successful" and being world's best is different - there are what, zero people in this list who can be considered top of the crop in more than one listed area?
So, to summarize, inertia.

I'm afraid merchants won't like this idea at all. Their domain name is hidden. Users bookmark plurchase instead of the merchant's site and there are endless opportunities to implement comparison shopping on top of it. I also wonder about SSL and certificates once it's checkout time.

This looks like an endless legal and technological battle against merchants. I'll be very intersted in the outcome because obviously wrapping sites via a proxy is a powerful technique for many things.
I haven't come across a scenario where openid did not work. Care to elaborate?

I think of openid as the git of the login systems. Elegant in it's simplicity but comes with a minor learning curve and the benefits of climbing the learning curve far outweigh the cost of doing so. And very much like git, it takes 15 minutes to get over the learning curve if you are good with google and/or have some guidance.

The fact that it's my product is unfortunate, but ultimately, I have to compete with them. I can only do that if I can make it easier to deal with my company than with the Pirate Bay.

A catalog of wealth creation mechanisms
Don't want to be rude, but ideas are a dime a dozen. An idea is only a "good idea" (in business terms mostly) when you have at least something to show in action.

What you consider to be a "groundbreaking" idea, can be considered as "meh" to people who knows what they are doing.

I don't think you need a "co-founder" (read: free developer), what you need right now is to hire a developer who can transfer you idea in to action.
One can always hope.
I agree. In Germany, we had an initiative called "Schulen ans Netz" (get schools online). It was all about uplink, neglecting the boxes and, above all, teaching resources. As one of my professors put it: "What are you going to do when all the schools are online? Take the first one offline again?".

On a side note, at the time the university was online of course (now they even have wifi), but there was no chalk in the (often overcrowded) seminar rooms and it was hard to get an OH projector or even a beamer for presentations.
