Facebook CEO: People Don’t Really Want Privacy Nowadays, Anyway | 80beats
There’s nothing like the launching a company from your college dorm room that achieves global Internet hegemony within a few years to make you think you can offer royal pronouncements about how the world has changed.
OK, so that was a bit melodramatic. But Facebook CEO Mark Zuckerberg earned some howls and guffaws in the last few days over his statements saying that, in a nutshell, people aren’t terribly interested in privacy anymore. Specifically, he said:
“In the last 5 or 6 years, blogging has taken off in a huge way and all these different services that have people sharing all this information. People have really gotten comfortable not only sharing more information and different kinds, but more openly and with more people. That social norm is just something that’s evolved over time.”
Some have interpreted his comments as an indication that he thinks that privacy is over and that the depth of privacy you might have expected, say, five years ago is very different to that you should expect today [BBC News]. The privacy changes that Facebook recently made—changes that ruffled plenty of feathers—seem to be in line with Zuckerberg’s statement. From last December onwards, all Facebook users’ status updates are made publicly available unless the user actively opts to change the settings and make [it] private. Users were alerted to changes via a ‘Notification’ posted in the bottom right hand corner of the site [The Telegraph].
The self-serving element of Zuckerberg’s statements wasn’t lost on some commenters, either. The more information that Facebook users share, the more information Facebook can vacuum into whatever ad-based revenue stream they’re debuting this quarter [The Atlantic].
Not everyone, though, was mocking the baby-faced CEO. Social networking is, by nature, anything but private. The fact is that if Facebook restricted and controlled the sharing of data the way some privacy groups would like, it wouldn’t really be a social networking site and it wouldn’t have over 350 million users willingly sharing information with each other. Joining a “social” networking site and then complaining that your information is being shared is like buying an ice cream sundae and complaining that it’s cold [PC World].
And as TechCrunch points out, credit-rating agencies have been making money by gathering an enormous database of personal information since long before Facebook existed. “Honestly, a picture of you taking a bong hit in college is mice nuts compared to the mountain of data that is gathered and exploited about every single one of us every single day. You just don’t really see that other stuff because those companies don’t like to talk about the data their gathering” [TechCrunch].

Island Hopping to Your own Island
Apologies for my lack of posts lately I have been feeling a little under the weather lately and needed to take a little break from the blog. However I am feeling much better and looking forward to reporting on all the hottest island properties around the world.
I recently came across an excellent article in the New York Times discussign the many benefits of island ownership. The article features Chris Krolow CEO of Private Islands Inc and discusses the advantages of both island ownership and island renting. To check out the article visit the New York Times.
Apple, It’s Time to Delete Bing From the App Store Too [Porn Iphone Apps]
Bing, Microsoft's dedicated web searcher, must be deleted from the iTunes App Store at once. Why? Its image browsing mode can be set to watch hardcore porn. If Apple wants to follow their own absurd rules, Bing must be obliterated.
Seriously, why is Bing still in the Apple store? Its image search engine is perfect to browse porn. Just go into preferences, turn off the adult content filter—one click—and boom, instant hardcore porn browser. And a very sleek one at that, too.
Would Apple delete Bing, which does what ForChan does but much easier and with much more explicit and unlimited results? My guess is that they won't, because Microsoft is Microsoft, not a no-name app developer.
They should, however, just to be consistent with their stupid "no-porn" policy. And if we are at it, let's delete the Camera and Photo album app too, because I can use them to take photos of my naked fiancee. Let's delete any app that can be used to record and transmit porn images online. Let's ban the sale of iPhones and MacBooks too.
Or maybe they should do the right thing, because all of this is just stupid: Stop censoring, let people decide what to do with their gadgets and software. At least when it comes to the content that we decide to store or access through our cellphones or computers.
Ransomware: Extortion via the Internet

Fact of the Day: Chrome Runs on Goats [Chrome]
It's a well known fact that Safari's CSS engine runs on rainbows, unicorns, and sugar, or that Internet Explorer 7 HTML renderer uses copious amount of babies' blood. However, very few people know that Chrome runs on goats.
Exactly, 12,000 goats are teleported every second after a fresh reboot. TWELVE THOUSAND GOATS, people. That's a lot of greek yogurt. Like, at least five thousand yogurts per second. Or ten. I'm not sure. Depends on the goat being african or european. Or if they are about to be roasted. So leave those poor goats, alone, Google, they have enough problems on their own.

Best Buy Is Epically Botching This TV Repair [Best Buy]
I once had to wait an extra four weeks for a couch. I was furious. All I can say is that I'm glad I'm not this dude on the Best Buy repair forums trying to get his TV fixed.
Just in case this post "mysteriously" disappears from the Best Buy site, here is the full story. We hope Best Buy can help get this guy taken care of:
It seems to take along time to get Best Buy to repair a tv!!!
I placed my first call back at the end of november. Complaint was green bloches and a green line in the middle of the screen. First date available is a week later. Before they get here the tv does snap crackle pop, smoke comes out the back and then no picture. Called BB and they say no problem, the tech has to see it anyway.
Tech looks at it and say he needs to order some parts. Writes down the serial number, model number and says will call after he knows parts have been delivered. One box with one part and second box will have three parts.
Week later a different tech calls to say he is coming and I tell him only one box is here. He says it shows both boxes have been delivered. Shows up and of course doesn't have needed parts. Says he will reorder. Writes down serial number and model number again. Another week later the tech arrives and opens the boxes. Wrong parts!! Writes down the serial number and model number again to reorder parts.
Another week later.....again......arrives and opens the boxes. Surprise....wrong parts.....again. Tech tries to solder part onto old board to get tv working. After about 2 hours says he can't fix the tv, will have to order parts. Writes down the serial number and model number....again. Say he will call me to confirm he ordered parts. Never received phone call.
I call the following week to check up on parts order only to find out no parts have been ordered. No reason why or when they will order parts. Geeks says they are having problem ordering parts. I ask how long they have had the problem. Two days he tells me. I tell him that parts were suppose to be ordered before then. He then tells me it has been longer than two days. I'm starting to get the feeling I'm running in circles.
Tech says he will order 6 parts and install them all in a effort to keep from coming back out again if there are still problems. They tell me they will contact and the tech and make sure someone calls me when the parts are ordered. No phone call...again.
Call back next week to find out when they are ordering parts. I was told they were ordered and delivered to my house already. Strange, I don't have any parts here. Geek says maybe the tech has them. I ask if we could actually confirm that or if he was just guessing. He says to call back tomorrow. Parts show up a couple days later.
Tech comes out to install the parts. Install two out of six parts and tells me it's fixed. Well......I can at least see the picture again. Remind tech that the original problem was never looked at because the tv blew before a tech arrived. He assures me this will fix that problem too. Told the tech it needs to run about a half hour before the green lines and blobs show up. I'm told to call back if there are any more problems.
I'm handed something like a ticket that says they have already spent over $1500.00 to try and fix this tv. It originally cost me $3000.00. What a surprise, half hour later the green blob is showing back up. I call BB and ask them to get the tech back. I am told he is now to far away. Have to schedule another day. I ask them to make sure the tech does not return the new parts he did not install. Was told they can always reorder them!!
So far it has been about six weeks of a dead tv. Then 30 mins of watching the tv to see the same problem I originally called about show up. Now I will sit home again and wait. Let them try and fix the problem. This is getting crazy!!!! How many times am I suppose to sit around and wait for people to come to try and fix this?? My time is actually worth something too. Even if no one else thinks so.
If the couch had me furious, this situation would have me on the verge of Geek Squad genocide. [Best Buy via Consumerist]
Microsoft Compares Android to an Adorable Puppy [Blockquote]
At first glance, this quote by Windows Manager James DeBragga doesn't make much sense. But it's actually a relatively reasonable metaphor.
He compares Android to a puppy thusly: sure, you can get a puppy for free, but then you've gotta housebreak it, take it for walks and train it. It takes a lot of work to turn that puppy into a properly-behaved dog.
And really, that seems to be true based on the initial experiences of Nexus One owners. But then again, that's one specific case. Every mobile platform, including Windows Mobile, has its issues. Are Android's really worse than most? [Laptop]
You, Too, Can Launch Your Own Nail Fashion Business! [Ces2010]
I'm going to tell you a tale, a tale of friendship that, with the help of a Chinese automatic nail printer, blossomed into a full-out, wet and sticky bromance.
There Jason and I were, walking through the International Center at CES, our shoulders brushing casually in the intimate walkways. Then we spotted a machine unlike any we'd seen before. A wizened Chinese man beckoned us into this booth, and before we could raise any objections, he placed his finger our our lips, a tacit acknowledgment that this was our first time. Jason took a seat.
Still confused and a bit disoriented, Jason smiled nervously as a camera photographed nothing less than the full earnestness his soul. Looking at the screen, Jason's stomach dropped at the sheer amount of honesty that could be captured on a webcam and displayed on a touchscreen LCD.
I pretended to ignore Jason's powerful image as grabbed a seat myself. The Chinese man took my hand—his touch was warm. He lightly stroked my thumb with a base coat while photographing me as well.
How would Jason and I frame our faces? We joked that the heart cutout was the only way. And then our eyes locked and we realized that maybe, just maybe, we weren't joking at all.
The photos processed, I tentatively placed my thumb into the machine. It clamped down on my appendage, strongly, and it wouldn't let go. At this moment, trapped and vulnerable, I could only let the machine finish. To this day, I don't know if it's the event's repression speaking, but the process was quick, professional and I don't recall the slightest bit of pain. In fact, I didn't feel a thing.
Jason, having bravely endured the same process, reveals the worthwhile aftermath in this photo. My face has been semi-permanently painted upon his fingernail. He blows on the finish to make sure it's dry, his lips the closest they'd ever been to my face.
"For better or worse, we're together in this thing now," I thought to myself. But just several days following this entire affair at CES, Jason and I have parted ways. Sometimes we IM one another, and there's the occasional text. But even as the heart has chipped away from my nail, his smile remains.
And if you'd like to duplicate the experience, the ArtPro Nail Printer runs about $1500, takes normal HP ink cartridges and breaks up to 6000 hearts between refills. The company is currently seeking US distribution.
Egg Energy Takes Netflix-Style Approach To Supplying Power In The Developing World [Batteries]
Created by a team from MIT and Harvard, Egg Energy is taking the Netflix style subscription model and applying it to a very unique for-profit business: supplying energy for populations in developing countries.
I'm not sure about the value of a dollar in Tanzania, but the Egg Energy's service seems like a decent deal. For a $27 first-year subscription, customers will get their home wired for electricity and receive a fully-charged, relatively compact battery that can be swapped out for a fresh one at a cost of 40 cents. As Earth2Tech notes:
The company explains in its executive summary that its target customer spends $5 per month on kerosene and $3 per month on AA batteries, with an average total of $96 per year for lighting and the use of a radio. But with eight swaps per month, the annual cost of the service in total is $65. "Switching to EGG-energy therefore saves a typical household $30.60 a year on its lighting and radio needs," says the company.
The first Egg Energy distribution center is already up and running on a well-trafficked route in rural Tanzania. They have acquired 60 customers since November and plan a rapid expansion in the coming year. [Egg Energy on Facebook via Eart2Tech via @Timoreilly via @TomRaferty]

Nano-Nascar? Tiny Dragster Has Chassis, Axles, & Buckyball Wheels | Discoblog
Because there’s no point in building a nanoscopic car that couldn’t crush other nanoscopic cars in a race, Rice University scientists have rolled out their best and baddest “nanodragster” ever. The car, 1/25,000th the size of a human hair, not only has a freely moving chassis but also can turn when one of its wheels is up in the air.
James Tour and his team previously made tiny cars that used carbon-60 molecules called “buckyballs” as wheels, but those wheels could turn on only hot surfaces, about 200 degrees Celsius. No longer. From Futurity.org:
The key to making nanodragsters, Tour says, was putting p-carborane wheels in the front and buckyballs in the back, getting the advantages of both. The front wheels roll easier, while the buckyballs grip the gold roadway well enough to be imaged by Kevin Kelly, an associate professor in the Department of Electrical and Computer Engineering. And the vehicle operates at a much lower temperature than previous nanovehicles.
“The trick to making these nanocars was to attach the smaller wheels first, then deactivate their reactive ends through carbon group attachments that we called ’scythes,’ much like blades on the centers of classical chariot wheels,” Tour says. “Then we could affix the larger C60 wheels to the rear axle.”
No word yet whether any potential nano-races will allow dragsters to gouge each other with those scythes, a la Ben-Hur.
