Did they spy on people using the web cam? NO! Because they weren't insane.

Instead, they simply built up a log of evidence from the machines' use (IP addresses, etc) and contacted the proper authorities. It got taken care of.

Web cam spying? Ugh. Sounds like some people developed a CSI complex. "Freeze it! Right there! Enhance! We've got you now, freshman!"

'ScaleDB is a pluggable storage engine for MySQL. It turns your MySQL application into an enterprise-class, highly-available, clustered database that scales dynamically in a public cloud, private cloud, or on premise.'

Is this better put by saying 'ScaleDB is a simple way to make your MySQL database scale automatically'? or something like that?

There are probably public services which would not be reasonable profit making entities but are very helpful for the society as a whole, and whose benefit is so widespread that it can only be repaid in collective good, goodwill, and/or taxes. For example, country infrastructure, primary education, healthcare, a security force, interpersonal relationships, religion, and love. Profit making organizations do sometimes create wealth and good operating out of their own self interest (though they also sometimes essentially steal it,) but there are other parts that need to function for society to be whole. That is the purpose of philanthropy: supporting the growth and perpetuation of businesses currently unable the pull together the resources themselves (efficiently, if possible, though not driven be the desire for maximum investor return.)

VDbench: The Amazing Swiss Army Knife of Benchmarks
I believe you are correct in that the threat of a filibuster is being used way more with each passing year.

(Might as well weigh in with an opinion)

Part of this is because politicians just don't like each other that much anymore -- nobody gets together for poker or dinner parties. That's a shame, and it hurts the country. Part of it is that Congress is under incredible scrutiny by cable news outlets, talk radio, and the blogs -- people are being sent there to fight an ideological battle, perhaps to the exclusion of doing the nation's business. Both sides are keeping these long lists of grievances with the other side. Lots of bitterness and lack of trust.

This isn't an unsolved problem, however. The Republic has a long history, and we've seen all kinds of partisanship in the past. Traditionally president of the party in power finds a few members of the opposite party and makes deals with them for bills. This usually ticks off the president's base, but it also splits the opposition and makes them ineffective. Once the opposition is split, moderates from both camps can join in to pass a bill with a dozen or so holdouts at both extremes voting against it. It's been done lots of times. Clinton very effectively did it when he announced "The era of big government is over" He took the other guy's issues and crafted bills that made it impossible for some of the other guys not to vote for them. Once he snagged a dozen or so Republicans, the rest of the process worked out fine. But it really ticked off his base!

I'm not seeing that same strategy being applied today -- perhaps because it wouldn't work. I don't know. I tend to think it would have worked a year ago. It may be too late now. Beats me.
I noticed that you mentioned people interests at Whole Foods. I try not to get into this argument. One's self interest is one's own, and it wouldn't be right to talk about another's interest as if it is my own. But this is the business's interest we are talking about, as an entity with a relationship with society.

What I see here is Mackey merging his and Whole Foods'. When he says "Put Customers Ahead of Investors", what does that really mean, that they don't care about operating at a loss? Sure, Mackey probably really cares about his customers and society, but Whole Foods as an entity doesn't have any special obligation with that. Whole Foods aim is to increase its profitability. If one way of doing so is donating some money so society, go ahead and do so. But it's not always so convenient this way (if donating scales with profitability, businesses would go ahead and donate all their earning).

Here's what Andrew is doing; he's being enterprising:

"An enterprising person is willing to try out new, unusual ways of doing or achieving something."

I'm not agreeing that this is the best route for him to take, in fact, I don't think it will work (I could be wrong) - but there's nothing wrong with trying new things.

Andrew is obviously testing this, just sitting back and absorbing these comments and the financial results of this test.

I don't think this exact model will work, but at any rate, good luck

So, the better way is just someone's pipedream? If you can't provide a suitable alternative, there's not much value there.

I think there's more value in updating one social network and having a bunch of different networks pick up on that so connections that are not on the original one stay updated as well.

I might be special in this case, but the different social networks I use don't have much overlap, connection-wise.
"What about artificial limbs for athletes? Where does enhancement stop?"

Sports is all about artificial restrictions. Not just banning drugs, but banning certain moves and behavior. That's what makes it a sport, and not real life. The idea is to see what people do under controlled conditions.

Now, exactly what those restrictions should be is a useful question. But the existence of restrictions in sports is a given, by definition.

"What about everyone then feeling pressured to enhance themselves to still be able to compete, if they want to or not?"

That's how it's always been. Modern drugs are new, but the idea of self-modification to improve one's lot in life is not. Dressing better, having a better build, being more handsome or beautiful, being (or seeming) smarter; all quite historic pursuits.

The world's a better place for it, overall.

I've read up a little more on the Chinese Room and I retract my argument. I misunderstood the idea.

I thought Searle was asserting that a human mind can be simulated by a dumb program that only provided cached responses. It's easy to show there are more than 10e50 possible conversational paths in a 15 minute conversation (even a chess game has that many, and conversation is more complex than chess), and there are only 10e50 atoms on earth.

But it seems Searle's real argument was that the man inside the box is performing all the actions of an artificially intelligent computer program, just with pencil and paper. Humans clearly perform such actions with just a few pounds of brain matter. Even if the Chinese Room operator requires continent-wide resources, such difficulties don't address the essence of Searle's argument.

He seems to be asserting there's something special about the brain called "intentionality" which is unlike a computer running an algorithm. He might be right, but there seems to be no evidence for such a thing, or any way to prove that an entity which claimed "intentionality" didn't really have it.
Regardless of whether the CTO is correct or not, the tone and poor attitude of his posts have convinced me that he is not someone I would want to do business with.

Yeah, that's great to have. If only there was a way to run the code without it being erased, so you can seamlessly work on a single piece and test it repeatedly.
The same strategy was applied. The stimulus was 1/3 tax cuts. How many republicans voted for it again?

How many republicans would vote for any healthcare bill? Even one that gave kittens to every republican in the country, spit in the eye of liberals and was named "the healthcare bill"?

I posted below that republicans filibustered PAYGO rules and a deficit reduction committee... right after filibustering the routine raising of the debt ceiling.

The republicans see a clear incentive to gridlock every single thing that goes through congress because they think people will blame it on the democrats. It's working out for them ok, so shame on us, I guess.
I'm not familiar with that work, but I was also going to say this is an illustration of how you can never really trust governments to always do the right thing.

The Architecture and Ambition of Craigslist
I've unlinked most of mine.

I use a bookmarklet to post most of the things I want to share to google reader, which feeds to buzz. I just have a handful of followers on buzz though, since everyone turned it off in the first few days. So it's not very efficient sharing.

But I turned off Twitter feeding into buzz, and into facebook. I use twitter in a pretty bursty way, and the feeds would be annoying on either buzz or fb. And twitter is great for spreading links, but not so good for disucssions on the links.

Facebook is ok for discussion of links, but people don't use it that way all that much. Plus I don't friend people I don't know there. And it's hard for things to spread on fb now.

Friendfeed was the ideal for me, but it's more or less dead at this point.

I suppose the answer is to make a fan or group on facebook and then try to round up followers for it.

My goal is to post interesting things and then have a discussion about some of them with interesting people.

There are many drawbacks of Skype for business use.
Just to name a few:
Outgoing Caller ID issues;
SkypeIn number does not offer many options on how to handle incoming calls;
SuperNode mode;
Share Desktop is peer 2 peer only, thus it does not work in a conference call;
Very limited call handling options;
etc
While I also prefer ruby, iPython and some of these other shells are dramatically better than irb, even with some of the nice irb add-ons.

I hope this won't sound wrong, this is mixergy's about page:

...I used credit cards and ingenuity to create a $30+ mil / year (in sales) internet business...

Sorry but after creating a $30+ mil annual sale company trying to sell videos for 25$ to max. 1000 people in a lifetime is not a great step forward for an entrepreneur.

Maybe he has a grand master plan to make more 30+$ mils with mixergy ....
Clearly, it hadn't been stolen -- but had it been reported stolen? It's a classic method of keeping something you're supposed to return. In that case, their activating the webcam would be perfectly in line with the stated policy.

Point being, there's still a lot of information we don't yet have. The policy of remotely monitoring the webcams is stupid, but beyond that, we don't know the specifics of why this particular webcam was activated or what the "improper behavior" was, so we don't know how much additional stupid there might be.
Your experience is different than mine. I usually have an acceptable-to-good experience when I call a credit card company, which happens often enough. I have always gotten excellent phone service from my car insurance company (Progressive). YMMV I suppose.

A medical call center like the one described in the article doesn't need to be a cost center. I could easily see them being run as standalone companies.

This link was posted a while ago here on HN, I believe.

It's more information dense, though it has testimonials from far fewer people. (That is, just one person.)
I have 8 desktops, each a different color.

I use particular desktops for specific tasks or projects.

If I'm toggling through desktops it's easy to see which is which by color. I know, for example, that ctrl-f5 takes me to where I have Thunderbird running. If I don't see the familiar dark blue desktop I know I've hit the wrong key combo.

It's one reason I went with KDE3 over Gnome. Having the same color on every desktop deprives me of useful navigation and organization info.

There seems to be a cognitive advantage to having a different color; it's like walking to a different room to do a different task. There's a useful context switch that helps me focus.
Skype IM really sucks. Both parties have to be online in order for the message to be delivered. What gives...? I got burned too many times on this 'feature' when my message was not delivered in time simply because my Skype was offline...
Perhaps you are right. Like I said, I don't know. It could be that Republicans are somehow much more recalcitrant than they were 20 years ago. It could also be that the administration has a more belligerent and inept political team than Clinton's administration did. Or a combination. Or something else. Remember that as the party in power, the administration's role (under the divide-and-conquer strategy) is to be accommodating and generous. Intimidating the minority party -- even if they deserve the bashing -- is just going to solidify their position and make the problem worse.

Hey. Just my opinion. I have a friend of mine that no matter what the subject can give me a list of all the bad things the Republicans did. I have another friend that can do the same for the Democrats.

I'm really glad that neither of these friends are in public office. :)

Advertising Wants to be Measurable – An Investment Thesis
IMHO that makes no sense.

The back catalog is more important to a real entrepreneur. Someone looking for entertainment in the disguise of education content would find the "hot" stuff interesting.

Someone building a business cares about specific topics because they are having issues with specific things like search engine marketing, sales people, partnerships, law, etc. That may or may not be covered by the latest "hot" stuff but a quick search in the back catalog is likely to turn up a good interview.

I'm Dutch ;-)

The government in the Netherlands fell because it was a terribly mismatched coalition to begin with and the issue of military intervention in Afghanistan was the last in a series of internal conflicts that made it unworkable.

(IMHO).

Generally speaking, the Dutch form of government, where people vote once every four years for parties they think should be part of a coalition government which then, basically, gets to do whatever it wants until it's voted out, is exactly what I had in mind when I wrote my original comment.

Once a government is in place, there's hardly any checks and balances to speak of, but once in a while you get the chance to vote out parties that have really made a mess of things.

() yes, I know that according to the constitution parliament has the last say in government. in practice, however, several parties commit to a coalition government and will defend it no matter what, even if said government does something they're absolutely against.
Skype's Voicemail is another drawback...
