Thank you so much, I was working on a computer vision utility for testing embedded medical devices over the summer, and used HSLA representations in a bunch of places. The old Wikipedia article was the best resource for explaining it to people, but it was still pretty crappy.

Your new one is a great improvement! I edited it to <!-- comment --> the TODOs to help avoid the wikisharks.

Now if you could only do the same for the articles on Y'CbCr and chroma subsampling :)
It's not that difficult. GMail does it. So, xyz@gmail.com requests to add abc@chat.facebook.com to its contact list. In the Facebook web interface, it comes up in the list of groups that you are requested to join, friends to confirm, etc. Privacy settings for vCard stuff (like image) can be the same as they are for Facebook - and Facbeook can use the Jabber ID of the other party (xyz@gmail.com) to see what their Facbeook account is for that or just give the public information (most people have a public profile picture).

SPAM and abuse isn't that hard. Remove the person from your contacts. Done. They can't contact you any more. Really, it's the same as if one of your Facbeook friends was creating SPAM or abuse.

Basically, it's just "friending" people by Jabber ID rather than by Facebook user id in a "chat contact" status.

There are technical challenges to federation and it did take Google a while to implement it. However, the UI, SPAM, and authorization parts don't seem that challenging. And it would be nice if Facebook opened up a bit. And Facebook might be working on this, but I don't think it's a UI issue. In the long run, it will come down to whether Facebook wants to be closed or open and that's a policy decision.
The company I work for does Adwords setup/optimization. I'm not too involved with that side of things, but I know that previous clients have experienced as much as a 250% increase in their business volume after starting adwords campaigns with us (relative to their pre-online-advertising sales)

Sure, this is hilarious. Take a moment to think about what it means. We all live in a bubble where the web is easy, where we can always find what we're looking for.

I'm convinced that some people approach the internet like an angry driver gripping the wheel without any sense of reality. Things like this remind me who we're often designing for and has to be done to make our work usable.

If > 50 people can arrive at a page, completely disregard the logo and read not a single word in the body BUT still find the comment form, something is wrong.

People are stupid. They are also our customers.
Low I.Q. Predicts Heart Disease
Ask HN: What do you think of my startup idea ? China and Ebay related
The concept behind the idea, is well grounded. I will give you an example : I have been selling watches on ebay lately,
and i noticed that at least 95% of the questions i received from people were: "Is this a original watch? or a knockoff copy?",
but this phenomena extends to other products as well, such as perfumes (which are more dangerous when fake because they can contain harmful chemicals impurities), bags, handbadgs, and a ton more kind of goods.
I was thinking to the relation this service could have with china, and its economic rise, and the fact that here fakes are almost legal.
Chine made promises to the international community when joined WTO in 2001. They told they were going to make counterfeits good illegal.
Some days ago i've asked a a smart woman who was selling counterfeit watches in Shenzhen LuoHu Commercial City :

Alberto Armandi: hey do u think china will ever put a stop on this ?
Chinese Woman : do u really want to know the truth ?
Alberto Armandi : yes, of course.
Chinese Woman : i think China will never do that because we , and our economy depends heavily on that.

So given the Chinese economy growth, and the seriously diffused "Chinese entrepreneurial mindset make money fast with counterfeit goods", i think ebay will have to cope with a lot of those nasty stuffs in the future.
This gives room for this kind of service i think.
I already bought domains : spotebayfake.com and fake-howto.com.
Both are related to keywords such as "how to spot fake", keywords that outputs some nice results if you look at volume of searches on google monthly.

It would not be billed with a monthly or whatever, subscription model, instead the customer would pay only for the item(s) he's interested to check.
I was thinking to SMS because transactions will be vary small. I have to read how Paypal deals with micropayments.
Regarding how the service would work, let's say you find a watch on ebay, like a Rolex watch, and you want to know it is fake or not, you come to our site and
submit the request for investigation, i will check the object ( i know something about how to spot counterfeits and replicas, i am in china since 2005 ), and i will provide
you an aswer, in terms of probability. All the process would not take more than 5 minutes, i do not think that real-time informations matter that much in this specifical case.
You will then pay let's say 1 USD to me for the information, and go on with your purchase or discard it.

here is a link to get a, not very precise, big picture of the market :

http://www.google.com/search?hl=en&source=hp&q=how+to+spot+fake&aq=f&aqi=g10&oq=

There are also some forums on ebay :

http://www.google.com/search?hl=en&newwindow=1&q=ebay+forums+how+to+spot+fake&aq=f&oq=&aqi=

What do you think ? is it worth implementing it ? let me know your feedback. it is precious.

Thanks so much in advance. Alberto Armandi
Google Buzz is brilliant, Facebook just lost half its value
That's pretty good. Basically, people who are prone to give up when they encounter resistance; people who are the opposite of tough.
Comment 103: "This reminds me of an article I read recently about the ever-escalating rate of illiteracy in America. It makes you wonder how these people ever make it down the street alive, much less how they are able to log into Facebook."
Why NASA Needs a Better Plan
It seems like a pretty logical step to go from cons cells to these conc structures. I wonder if Rich Hickey knows about this and can get it into Clojure somehow (if it isn't already being used somewhere). It seems like a perfect fit for Clojure.
Interesting, I hadn't heard of that. Of course there will be lawsuits, but my point was that by current definitions they should not be in violation of cable franchise agreements, even if they are allowing users to download full-feature films in < 5 minutes.
This is my least-favorite Internet meme. People "pipe cats" because they want the entire pipeline to read left-to-right, like:

cat file | xargs foo | grep bar | sort | wc -l

It just looks nicer than:

< file xargs foo | grep bar ...
I'll go along with it as long as you can't retrieve the data without a subpoena (which I assume is easy to acquire during an accident investigation, but much more difficult to acquire "by asking").
Glitch, the new MMO that tech bloggers adore
A favorite quote:

"Especially in Silicon Valley, where it's easy for entrepreneurs to isolate themselves in circles with like-minded techies and fellow entrepreneurs, I feel that a huge amount of startup CEOs and designers... make product decisions that appeal to their own interaction behaviour with such applications or what they think their friends will find cool.

"Building for geeks makes for great customer immersion if you're building something like (the wonderfully useful) GitHub, but that same process doesn't work so hot if you're building a site for middle-aged moms."

It's not a shame: it's an opportunity for another person to startup a Y-combinator clone but without the cutoff.

Every limit you put on your business is an opening for a competitor. Why should this be any different?
Possibly OT but I knew I recognized your username around here and a glance at your profile reminds me you run http://mightybrand.com

I'm genuinely curious what makes you (and others) start new projects when I would think you have (or should have) your hands full with seeing how far one can go? In other words why and how do you feel your time is better spent starting a new project as opposed to improving/optimizing your current one? Is it a matter of burnout and just needing something different to think about? I guess I've always thought that running a business entailed hundreds of hats as it is, and optimizing different areas of your business would always leave you with something different to do.

Genuinely interested on your motivations if you don't mind.
Oh man. So they have to up their censorship efforts while establishing and maintaining a nationwide email system... and deal with the huge backlash when those inconvenienced by the move (ie: damn near everybody that has a few thousand emails and contacts already firmly entrenched in gmail) at the same time.

I feel sorry for the folks that are going to be ordered to directly implement all of this.
I don't know of any real market changers from microsoft, save IE, which was an attempt to kill competition and preserve market. Maybe I am too far from the microsoft circle to know of any...
It seems a bit arbitrary to just chop up a flat fee and pay it out equally once a month to all the content providers I "flattred"; it's sort of like saying everything was of equal value, which probably isn't the case. However, from Flattr's point of view, I see how this makes it a lot easier to manage as far as distributing funds goes.
I would also add that not all tools follow the '-' convention, and the ones that do can break in corner-cases. Why invest the effort of remembering how every tool works and which ones don't, for a obfuscating micro-optimization? /proud useless user of cat
RWW Writer here: these people are all coming to our site by searching Google for "facebook login"

Very sad, but I guess it's really a good reminder that we live in a bubble. For a lot of people, the Internet is magic and they don't know what to do when something changes.
The cake is a lie. This is exactly like contenture, which shut down:
http://techcrunch.com/2009/12/21/the-anti-ad-network-content...

God knows I think it would work in theory.

I really like what http://kickstarter.com is doing in this space. But really, commerce is more important than this kind of P2P system. Easy payments != voluntary micropayments for free content.

edit: so contenture didn't involve explicit clicks like flattr, but I think the analogy still sticks.
I'm really trying to give the commenters the benefit of the doubt. In their defense, Facebook was gradually rolling out a new design that its users seem to despise. That, combined with a usage spike from massive snowstorms (school/work closings, closed roads), explains some of the desperation. I hope.

This is also exposes a massive downside to implementing Facebook connect.

All About The Features
What is the revenue model for the company? percentage off of the monthly flat rate I assume?
Actually, the author of the blog I linked mentions a few times that all non-industrial cultures were fermenting their grains before eating them, which is supposed to get rid of antinutrients such as lectins or phytic acid. But I did not go deep into the details of that.

And no, paleo does not mean eating raw red meet - cooked is fine according to most sources I came across. Some indeed do eat raw, but I think it's the 'hardcore' minority.
It's the users. Facebook's value isn't going to vary any unless there is some migration from Facebook to Buzz.

What exactly does Buzz offer that Facebook doesn't? What kind of recognition will it have?

This is all very interesting, but it's _far_ too early for this kind of hyperbole.
Companies like sony have much capital tied up in movie theaters right? This would be a negative impact to those revenue generation mechanisms.
can someone confirm that login info is sent in the clear? that's pretty terrible.
The never fire, never layoff policies make it critical to hire the right people. Wonder if that causes stress. It would keep me awake at night.

Web developers: There's no excuse for device incompatibility
The most useful thing I took away from this was not 'piping cats' but instead the interesting syntax for creating multiple directories in one go:

Would be better with a camel as an example and not a cake because thats what many industries has to swallow to get into this model. Interesting approach though. Micropayment is a nut that needs to be cracked and if browsers vendors doesn't do it someone else should.

Apparently it's down to ~$1,000 if you assume 100% take rate and don't attempt to serve rural areas, but it will easily exceed $2,000 in realistic deployments.

In Utah if you're willing to pay for your fiber upfront it's only $3,000. And then you still have to pay the monthly fee for Internet access on top of that. http://www.app-rising.com/2009/11/utopia_proving_new_option_...
The Vioxx Story
What instructions? I couldn't find any, and so I can't authenticate. In particular, I have no idea what the correct server would be.
It should be pointed out, since the article does not, that that is merely one example of shell expansion that can be used anywhere. It is not a mkdir feature.

$ echo project/{lib/ext,bin,src,doc/{html,info,pdf},demo/stat/a}
project/lib/ext project/bin project/src project/doc/html

I made a "hello world" sort of buzz post as soon as I got it a few days ago. Last night I looked at my public google profile (http://www.google.com/profiles/<username>) and was shocked to see that my buzz post was shown on there. Yes, I allowed that first post to be "public", but its not immediately clear how public that actually is. I had assumed that it meant public to all of my buzz followers but apparently it meant public to the entire world.
Flagged.

RWW is really pushing against HN, huh? First they tried to get high-karma members of the site to link to them (http://news.ycombinator.com/item?id=1103021). Now, they are posting themselves really cheap links, to things that really don't matter.

I am sensitized to it on the issue of art. The word is in the class of words that are content free and should never be used without at least some cursory stab at which of the virtually infinite definitions you actually mean.

"TV isn't art" carries a lot of connotation, but no actual denotation. I object to just lobbing the connotation into a conversation and acting as if something has actually been established.

Turn 100 developers loose and amazing things happen to your "source code" repository.

Or don't do that. git users are happy about git in part because they don't work with idiots that misuse their tools.
Speak for yourself, and I don't know anyone that puts the input redirection first. I do this:

(xargs foo | grep bar | sort | wc -l) < file

It makes the pipeline one command, both lexically (verb comes first) and concretely (the pipeline is kicked off in a subshell)
My friend lists correspond to privacy settings, not human-friendly groups (just photos, nothing, professional contacts). They should divorce friend lists from chat groups.

"Critical...?" Yeah, critical in that if you make one particularly wrong hire (the sort who drags down others, see e.g. the Corncob Antipattern), your company is dead.

One of the things I always checked about a startup I was considering joining was if they were capable of firing people.
Ask HN: Why is it a pain to run OS X in windows?
Why is it easy to run Windows on a Mac using software like Parallels but a pain to run the Mac OS in Windows?

Makes me think its smarter to just buy a Mac. Sure, its a little more money but at least you have access to both OS's.
That's a fair question. It's partly some burnout and needing a new challenge. It's partly that this took me a weekend or two to build (and most of it was built before we started MightyBrand, to be honest), and I hated the thought of throwing it away without seeing what kind of response it would get. And if I'm honest with myself, part of it might be a mistake on my part. I'll have to think about it some more.

Pretty funny.
The problem is easily solved with smaller, more frequent commits.

In SVN, your changes had to be "ready to check in", which was this big, complicated ritual where you back up your changes, update, merge, check to see if the merge screwed with your changes, replace your backed up files, diff, unfuck the merge, and finally, commit.

With DVCSs, there's no reason not to commit partially done features. If you're at enough of a stopping point to want to merge in other people's changes, you're at enough of a stopping point to commit what you have so far. Your code only needs to be "ready" when you push it out.

Sometimes you can use /dev/fd/0, but I agree, it's a stupid micro optimization, and I don't understand why people get so righteous about it. My co-worker would correct you every time he saw it, but then again he's a pedantic geek.

"I have this great idea for a *video game*, I just need someone to build it. How do I find a *coder* and build this *video game* in a couple months?".

This happens so often on gamedev-related forums it's depressing. Pure beginners often lack the gumption, or perhaps just the knowledge, to realize that they could and usually should just do everything themselves, or at least learn how to code a game or use a game making application.

In these days of 200-person AAA development teams I can understand the sentiment that developers by nature are super-specialized, and that having multiple skillsets just doesn't compute.

I'll come right out and admit that I still use Subversion. And like it.

That seems like a crime to most people because I'm a Rails coder, but the truth is that I haven't had any need of anything else yet. I'm generally the only person working on my projects which means that Subversion meets all my needs.

I'm sure that there are benefits to converting, but every time I start the process I get turned off by having to learn a whole new way of doing things...

For now: I'm sticking with Subversion.

Here's a simple way to do it in Loom (https://loom.cc/faq).

The customer visits a paid content site, let's call it https://valuable-information.com. The customer's browser has a cookie for that site which stores a Loom location (an ID such as 1d425bd38f6520e6fab684a18b9c924e). A pile of assets sits at that location.

When the customer views a paid article at valuable-information.com, the site debits that Loom location accordingly. Or, if the site uses a monthly charge, it debits the location once on the first of each month.

The location also serves as an identity for storing the customer's preferences.

When the balance gets low, the customer can "top off" the location however she likes. If she decides to stop using the site, she can sweep all the assets away from the location.

The speeds are 1 gigabit connections. The Dark Knight Blu Ray was approx. 35GiB. At 1 gigabit connections speed it would take 280 seconds in a best case scenario.
