Python & twisted or jython & jetty/nio/netty
Hello all, I'm trying to get started on writing a chat server that can handle many concurrent connections(~150,000+); it will be a component of a webapp underway. I've been reading all sorts of stories, reviews, and such --many on here as well. Specifically, I really enjoyed abstractbill's story about working at justin.tv, and writing their backend in twisted. If this approach is scalable and probably quicker to develop, considering its in python, I don't see why more companies don't go this route? (btw, I'm not implying disbelief, I'm really just wondering why)

I have narrowed my options down to using python and twisted, or using a java backend with some jython and using netty for the comet tasks. I also read that netty on jboss takes quite a toll on memory; but that using a java backend should be faster than python. I'd really appreciate if you guys can help me out a bit; enough to finally make a decision. (fyi, issues about which language/technology is more knowledgeable are NOT a factor) Which is the better approach for a comet powered chat component?
Good point, you're of course correct.

Same result to the people on the bottom/outside though.

I'm not sure that a deficit of 12% of GDP (all of which has been monetized for the last half year) is "not high." If this deficit spending were actually going to financial institutions and disappearing (which is happening with much of the fed's lending of late, but primarily because the few borrowers who are qualified are not enamored with leverage at the moment), you would have a point, but our government is spending that money as it normally would: 58% of federal spending is entitlement programs, 19% is for killing people on the other side of the world, and the remaining 23% is sprinkled among programs that are each too small to be worth mentioning.
But I dip in and out of the flow. If I see an IM window blinking, I can ease myself out, get the code to the point at which I can re-enter smoothly, it only takes a minute or two usually. Whereas even "are you busy?", most annoying question ever, is enough to jolt me out.
I remember when that easter egg required holding option, opening the Apple menu, selecting the About This Mac menuitem, and then doing something to the resulting window (I forget what, but I think it was a combination of modifiers and a carefully-placed click).
Re HN Raplet - I'd be eager to try that out. Got a link?
Fair enough, and if that's what people want to do, then by all means do so.
Based on the way they've operated their business to this point, I have no reason to believe they have such a plan.

There are things we know, such that Groupon is known to negotiate very aggressively with local businesses to get the best possible deals. We also know that there's strong competition to Groupon negotiating with the same (or at least a similar set of) businesses. That fact alone suggests to me that Groupon will not be able to negotiate as strongly as they currently do--therefore their COGS will go up.

We also can see a trend where as their revenue has grown, their expense growth has actually outpaced their revenue growth. While that means they haven't found efficiencies that no doubt exist in their business, the fact that their expense growth is outpacing their revenue growth suggests that they aren't even LOOKING for those efficiencies.

Finally, there's the evidence that (like many tech companies before it) that investment up to this point in Groupon has basically operated as a ponzi scheme--taking new investments and paying that capital out to earlier investors. Sadly, that's a really dangerous indication of their real reasons for doing an IPO--raise capital so the last of the early investors can cash out.

I'm not saying a business like Groupon can't succeed and can't have a legitimate IPO--but I see no evidence that Groupon is really that business.
Any and all that he signs, or he shouldn't be signing it into law.

For what it'a worth, my comment ends on a very "Meh, who cares?" note. I don't know where that puts me in the context of your agonizing over our society's depressing descent into Manichaean dichotomies.

P.S. My suggestion was intentionally absurd. I think it's more likely that, like someone else suggested, this patent would be used to prevent people from exploiting such systems.

From earlier today (since it's related, especially the HN comments): http://news.ycombinator.com/item?id=2612245

Personally, I would be wary of using any contract written by someone who isn't a lawyer. Telling people that you feel "there is no need to state the obvious as many contracts do" doesn't instil a lot of confidence either: how do you know what needs to be explicitly stated and what doesn't?
I think that very early on, picking AMZN as a winner is luck. But the difference between them and their competitors (even in the early days) was constant innovation both in technology and business. For example, one-click purchasing, free shipping on orders over $25, users also viewed, reviews etc.

Much of what they did is par for the course today but, at the time, it was innovative. Amazon didn't win because they were lucky. They won because they were smart. Investors who recognized this were betting intelligently, not just lucky.

The other thing to notice is that that culture still exists today. They take big chances in areas seem tangential to their business (eg. AWS, Kindle) or use business innovation to drive sales (eg. Amazon Mom).
How about paying for proper server resources? I mean fuck... it's down every day multiple times.
Now just imagine if people went around trying to scare each other with wild speculation based on scarce evidence and no rational arguments. What would that be like?
No, developer mode is something you have to do if you want root access to install Ubuntu or others.

The technology described kind of reminds me of the "Ugly T-Shirt" in Gibson's Zero History.
"IANAL, but in this case I would assume that 'those consequences' would be that copyright holder X was harmed. If that's the case, then there was no way that the user intended to harm copyright holder X by downloading something they thought was by copyright holder Y."

You're comment is what a lawyer would use in an argument that the plaintiff lacks standing. And it certainly might prevail in this case (I've not seen a copy of the pleading).

But if you look at this thread (or at least my contributions to it) you'll notice that I've never expressed any opinion one way or another about whether or not Titan Media will prevail in its efforts. I make only three claims;

1) People sued by Titan Media will feel inconvienienced by it and they will associate the suit with their action of downloading "something" from the internet.

2) Those people will associate 'downloading stuff from the internet' with this inconvience.

3) They (and their friends who had to listen to their tale) will stop doing this because the 'risk' has risen above the 'reward.'

I used the short hand of relating this process as 'educating the naive.' I stand by that analysis.
Interesting to see Jason Fried (presumably the one from 37 signals) in the stock sale list.
Of course it can be, because as I already pointed out "overrepresented" is in the eye of the beholder. There is no empirical measure of it, its just an opinion.
T.I.L. Mail filtering with procmail-lib and better procmail docs
So today I started to fix my annoyances with procmail, but since procmail uses IMHO a very arcane syntax it usually takes a long time to do the things I want (such as automatic mailinglist filtering).

I use procmail to filter my mail on the server, so I don't have to access the mail with an (imap) client first to get it sorted. I use it mostly to keep my personal and business mail separated from mailinglists. The latter wasn't working well enough and resulted sometimes in mail being delivered to the wrong mailbox.

Thanks to the procmail-lib project[1] and the procmail documentation project[2] it now works a lot better and I understand the horrible procmail syntax a bit better!

Thanks Jari Aalto for all your hard work invested in these projects!

Actually I think it is crucial to: a) put a really interesting headline, b) additionally: list 1-3 top features that establish and differentiate your service/product, c) put a "leave your e-mail" text box with dummy "your@email.com" content so that there is no doubt it is to leave your e-mail, d) ensure there is no more text on the page besides the above, so the page as a whole is tidy, nice and clean. And don't afraid of using large fonts.

You really think sheets of visible light transparent but IR opaque plastic are going to be outlawed? Do you think your favorite band is really going to allow such a device to be enabled during one of their shows, thus pissing off their fans? Do you really think some company is going to bring a DMCA circumvention device suit against iPhone case manufacturers?

Are you willing to wager? I'm feeling lucky: I'll bet you $100 that ten years from now you'll be able to real-time stream 3D holographic recordings of the Rolling Stones directly to your Facebook friends.

>there is no problem to generate a billion revenue that costs a billion and half. Barings bank in 1995, Enron in 2002, Merrill Lynch in 2008 ...

In all three of these cases, you have situations where sophisticated financial instruments were used to hide real losses or very risky and costly investment bets.

That's a very different situation than one where you're leveraging debt to gobble up market share to become the market leader for a certain kind of service. This is particularly useful in types of businesses where winner takes all.

Hmm... interesting, it appears that average private school tuition is over $3000 less than the average public school expenditure per pupil and there are better student teacher ratios. Wonder why he's not asking to be turned into a private school?

Also it appears that public school spending has only gone up over the long term. How about a "thank you for the most funding in 100 years" letter from this administrator? Or perhaps a "I'm sorry we continue to fail at educating despite record funding levels" letter. No?

Oh well I guess he decided to go with "We babysit for 7 hours a day and get three months off, but we should be funded the same as institutions that provide 24x7x365 care of violent adults."

As some of the article commenters have pointed out:

7,000/180/7 = $5.55 per hour

Another imaginary currency. Very bad.

Bitcoin is just another imaginary currency. But now its technofreaks imagining it, what a difference. A real adventure into economics and currencies would be to strive for a society with no currency, where people do things for the lulz. Not for the coins man.
Ask HN: Successful hardware startup in entertainment. How can we go consumer?
We're iLuminate, a bootstrapped hardware / software startup working our way downmarket from the entertainment industry, and we'd love to hear your advice on how to get our product into consumer's hands. You may have seen us on America's Got Talent Tuesday night, or the HN thread "Dancing hackers create iLuminate system for performance art" <http://news.ycombinator.com/item?id=2606038> a few days ago. People really go nuts for the synchronized lighting, music and movement combination.

After two years of hard work and experience in live entertainment, we know we've got a solidly engineered product and a great team behind it. But none of us have experience bringing consumer devices to a large market. It's a bit daunting. Should we partner up with a company who does, perhaps licensing out the tech? Bring someone on board to run the consumer side of the business? Seek outside investment?

If you're a hardware hacker that went to the consumer market, what challenges have you faced?

Thanks to everyone in advance!

Everyone I know who actually got a cr48 just wanted a free laptop, saw the news on slickdeals or a similar site, gamed the signup process and ended up running Windows or Ubuntu on it. Meanwhile the couple of people I know (including myself) who wanted to actually try ChromeOS out in the real world to see if it makes for a suitable netbook OS got nothing but belated invitations to buy Samsung's new Chromebook.

Perhaps at least part of the reason that nobody has found the easter egg in the cr48 was that the way they were distributed was far too random to get them into the hands of people who really wanted to use and/or hack on them as ChromeOS devices.
Then why would it matter if it got hacked? Surely they aren't conducting any official government "business" on their personal Gmail account, right?

One problem with putting blinders on yourself is that you lose touch with the zeitgeist of a site like this. Also, is it worth creating and installing browser extensions for flurries of stories that usually peter out after a week or so? Obviously some people think so and that's fine, but I think it's silly.

On one hand I think a common semantic framework is inevitable. On the other it just looks like the search providers further encouraging the manipulation of search engine algorithms - another round in the SEO arms race in which consumer oriented interests are increasingly drowning out non-commercial speech on the web - e.g. Googling "weather" in the US returns forecasts from commercial sites but not NOAA's local forcast.

Feels like Groupon is doing something similar. With Google and Facebook moving closer into local deals and LivingSocial nipping at its heels, its only a matter of time before Groupon starts feeling the heat.

Look at the distributions of the types of people that vote up the story, look at the differences in the average number of upvotes once it hits the front page, look at how many people flag it, but if you need to hard code things that legit users upvote you are basically imposing your view of what is good content over thousands of other people. This isn't a Viagra ad, this is a cryptography based, near-zero transaction fee, distributed, open source, online currency.

No wonder it always hits the front page, any of those five categories could hit the front page.
They neglected a format for job listings, which is unfortunate. We (LinkUp) put one together at http://wp.me/pJYG0-1H, it will be interesting to see if it gets any attraction and if they're actually seeking external input.
If a growing company is too big for VC's to handle, it has to IPO to continue gathering investment. Especially if it's capital-intensive. Amazon did this in 1997 and that doesn't seem to have been a disaster.
When did Apple sue iOS jailbreakers? Did it go to court or did the defendants settle?

If you take your analogy to completion it makes perfect sense.

Let's say you're in the business of giving $10 for $9.

Let's say you become so popular at it that you beat out all your competitors and now whenever anybody wants to make $1 comes to you and goes to no one else. So multiply this by the size of your market.

Now you add the condition (or maybe you had it in the first place) that those $9 have to stay with you at least 10 years. Now you're pretty much running a bank (well perhaps a CD is closer in terms of return and style of investment.

That's a real business. It's not just leveraging capital but now you're the only bank out there so you've pretty much got a monopoly going. Now you can change your terms and say instead of giving back a $1 maybe you only give back $0.50 or $0.25. What is everyone else going to do about it since you have so much power in the industry you can crush your competition?
Good point. In your home yes, but not everywhere.

I'm not saying there's no logic. I'm just saying it's some pretty messed up logic.

Sony has been targeted for several major intrusions lately and I'm certain they have lost a great deal of money because of it.

Now if hackers want to damage Sony, how about finding a way that doesn't also involve millions of regular people in the process.

I got my one and only Sony product (PS3) because I use it for something. Not because I support Sony in every decision they make, and I definitely think they should do something about that joke for security they have going on.

But why should the user be punished and shat on by some idiot hackers just because he/she decided they wanted a cheap system to play games on, for example?

They could do a million things to hurt Sony financially instead of fucking over millions of end users who aren't connected to the company at all. (I'm counting all the affected users of all the latest Sony attacks, in case someone has a problem with the figures.)

Also, I think they chose to release the stolen data out of ill-will towards Sony rather than it being an attempt to point out security flaws. Because if security flaws where the real issue they attack Sony, then they wouldn't release the info to everyone since that seems quite counter intuitive.

Funny, I didn't notice until you mentioned that. It is nicely written, and apostrophe use seems all right. :-)

Not sure if I buy the "as a kid would write" bit, but it is surprising to see this. Maybe the hacker just took 10 mins and proofread his own text?
I think that all we should do is wait and see. This is all very interesting and unpredictable. It is at least a good experiment. If you are going put money into the system, well it is at your own risk. Nobody who does not sign up is at any risk.

This is Doug, Hipster's CEO. I'm happy to share the results of the campaign (if you're interested).

Yesterday, we launched the following page:
jobs.useHipster.com

Essentially, we're offering a years worth of PBR, $10,000, and a whole bunch of Hipster swag if we end up hiring someone you refer.

The results are blowing us away. Here are the results of the campaign to date:

Yesterday, we had 12,296 unique visits to our jobs page.
So far, 24 hours in, we've gotten 240 applications.

50% of those are for marketing / BD / sales / joke candidates, so not helpful.

40% of the applications are for developers, ranging in quality and location (not right for us, but potentially for others).

However, 10% of the applicants (so about 25 of them) are A+ candidates - people from our competitors, and from Google, Twitter, SalesForce, Oracle, AOL, and other top startups. All 20 of these people are seemingly eager to join.

Getting these 20 people into interviews would have cost hundreds of thousands in recruiter's fees, and we did it for free.

If you have questions about how we did this, feel free to email me at Doug (at) useHipster.com
