Apple, It’s Time to Delete Safari From the iPhone [Rant]
It took only a few hours: Apple has banned ForChan from iTunes, a perfectly innocent, web-based, dedicated image browser for the iPhone. Its only sin: It could display porn. Well done, Apple. Let's delete Safari now.
ForChan could connect to any image board web page and show pictures. Photos of dogs, cats, birds, food, cars, planes, flowers, scenes of summer, winter, and fall, or anything in between. Anything including boobs and buttocks:
It didn't promote porn in any way. It didn't have any ads for porn. Its icon was plain. Its explanatory text was perfectly innocent. And yes, while the developer mentions that it could be used to browse pictures of fully naked girls—and has some boards with that kind of pictures—the app itself is not a "porn app." Actually, you had to click a few times in the web before getting to the smut. There was no magic "Show me the tits" button.
In fact, ForChan only has two options: Browse page after page of images, or enter a new URL to access a new web server containing different images.
Sounds familiar?
Yes, exactly the same as Safari. Enter any porn web site address in your Safari URL field, and you will instantly get connected to porn. Hardcore picture after hardcore picture, wet video after wet video, all the perversions imaginable, no niche left untouched.
So why is Safari in the iPhone? Is it because web-browser porn browsing is socially accepted, leaving the ultimate responsibility in the individual using the web browser—often with a convenient privacy mode?
If that's the case, why delete ForChan from the iTunes Store? It's a web browser too, no matter how image oriented it is. Apple is not selling porn in the Store when somebody purchases ForChan. They are selling a generic browser, just like the built-in Safari is. One that can only display images, any kind of images, just like the built-in Safari does.
Apple includes Safari with no restrictions because, at the end of the day, it is your responsibility to use your web browser according to your own set of moral and social rules. You can write a new web address and access Fleshbot instead of Gawker. Your action, your choice. Nobody is going to go to Apple and accuse them of selling a porn app because I can access porn online. And nobody can accuse Apple of selling porn by making ForChan available in their app store.
So why retire it? Just because we highlighted that it can be used to browse porn. So here's a hint, Apple:
Time to delete Safari.

eReaders Go Bonkers At CES, Sales Expected to Double...Should We Be Scared?
Last year it was all about the netbooks. This year, it's all about the e-readers. e-Readers are so hot at CES this year that they received their own Tech Zone. CEA expects that their sales will double in the next year, and considering the explosion of models and accessories being shown off at CES, it's not hard to agree that's a reasonable expectation. But, looking at some of the other technology and buzz words at CES, is this a market destined to become a massive pile of obsolete gadgets in the very near future?

Control Your PC With the Puyocon Motion-Sensing Ball [Motion Sensing Input]
Using a mouse is old-hat, if the recent wave of ball-shaped motion-sensing PC remotes is anything to go by. Straight out of Japan, the Puyocon can be squeezed, thrown around or rolled, controlling actions on the computer.
The Entertainment Computing Laboratory, at Tsukuba University in Japan, should hook up with Cambridge Consultants, whose Suma controller has been designed especially for PC gaming. Both ideas are very interesting, taking the Wiimote as influence, with 14 pressure sensors, a three-way acceleration sensor and Bluetooth taking up the core parts of the Puyocon. Could these balls wipe out traditional computer mice in the future?
Check out the video below for a demo of how the Puyocon is used. [Puyocon via Crunchgear]
Google May Insert Real-Time Ads Onto Old Billboards in Street View [Google]
All those outdated billboards in Google Street View aren't just an eyesore; they're a waste of a money-making opportunity for the big G, apparently. But not for long.
Google's filed a patent entitled "Claiming Real Estate in Panoramic or 3D Mapping Environments for Advertising," and it should allow them to automagically cut out billboards shown in Street View and replace them with their own current ads.
In theory, this would be done in concert with whoever owns the space, so a theater owner could keep the posters out front up to date at all times. This seems to be the only way for Google to get away with doing this, as if they suddenly started sticking ads on other people's property without their permission, things could get ugly fast.

Amtrak Finally Getting Free Wi-Fi, But Only on Acela [Wi-Fi]
Take heart, business travelers of America! Soon you'll be able to add "slow and spotty internet connection" to your list of gripes with Amtrak's high(er) speed Acela line. While I'm sure Hulu will help numb the pain of rail commuting, be warned that it may only be free for a limited time. Also, be annoyed that JetBlue had free Wi-Fi in a plane more than two years before Amtrak could get its act together for a ground-based service. [Wired]
How the Texas Textbook Censors Got Onto Climate Change | The Intersection
Joe Romm has an important post about the folks down in Texas who are constantly trying to bring the textbooks into line with ideology. This is something we usually think of as affecting the evolution issue, but no–climate change is also a topic that is being watched closely by the watchers of educational content.
Romm himself is linking a Washington Monthly piece called “Revisionaries,” which reports the following:
A similar scenario played out during the battle over science standards, which reached a crescendo in early 2009. Despite the overwhelming consensus among scientists that climate change exists, the group rammed through a last-minute amendment requiring students to “analyze and evaluate different views on the existence of global warming.” This, in essence, mandates the teaching of climate-change denial. What’s more, they scrubbed the standards of any reference to the fact that the universe is roughly fourteen billion years old, because this timeline conflicts with biblical accounts of creation.
The strategy is identical, isn’t it? “Critically analyze” evolution, “critically analyze” climate change…and smuggle bad science into the classroom to sow doubt and confuse the kids. Frankly, I am wondering these days if climate denial may not be growing into an even more massive phenomenon than evolution denial in the US. I doubt it has the potential to be as long-lived. But the intensity of it, which I feel every day now, simply dwarfs what’s going on in the evolution fight….
Wet Computers Headed to Fill Your Body With Drugs and Love [Science]
Wet computers—devices made of lipid-covered cells that handle chemical reactions similarly to neurons—are the key to machines with the processing power of the human brain. But for now, they may deliver drugs in a better way:
The type of wet information technology we are working towards will not find its near-term application in running business software, but it will open up application domains where current IT does not offer any solutions - controlling molecular robots, fine-grained control of chemical assembly, and intelligent drugs that process the chemical signals of the human body and act according to the local biochemical state of the cell.
That's what University of Southampton's Klaus-Peter Zauner says, pointing out that the molecular computer they are working on is a "a very crude abstraction of what neurons do." When the lipid-covered cells contact each other, a passage opens between them so chemical reactions can pass from one to the next. Inside the cells, a reaction—called the Belousov-Zhabotinsky or B-Z—happens, triggered by other cells. This reaction can pass from one cell to the next, or can be contained within the cell, allowing for cell networking, which is key to form these wet processors.
Did you get any of that? Good. I just like the idea of my processors getting wet. [BBC]
Tiny Tern Makes World-Record 44,000-Mile Migration | 80beats
If you thought George Clooney’s character in “Up in the Air” racked up a lot of frequent flyer miles, you should meet his avian rival, which flies the equivalent of three round trips to the moon and back during its lifespan. For a study in the Proceedings of the National Academy of Sciences, researchers tracked the arduous migration of the tiny Arctic tern and found that it flies an average of 44,000 miles every year on its trip from Greenland to Antarctica and back. That’s a new world record.
Scientists suspected that this tern could best the previous world record of 39,000-mile migrations by the sooty shearwater, though they previously lacked tracking devices small enough for the bird to carry. But the team used a tiny tracker developed by the British Antarctic Survey, which weighs just a twentieth of an ounce (1.4 grams)—light enough for an Arctic tern to carry on a band around its leg [National Geographic]. This device reported the birds’ position twice daily.
The locating devices reported back a few surprises. It turns out that the birds did not immediately travel south, but spent almost a month at sea in the middle of the North Atlantic Ocean. The researchers believe the birds use this lengthy stop-over as a chance to “fuel-up” with food before continuing on to less fruitful waters farther south [LiveScience]. In addition, the birds don’t fly a direct path from Greenland to Antarctica and back, but zigzag across the Atlantic Ocean—the map’s yellow lines show the terns jogging between Africa and South America on their northward journey in the spring.
These diversions took advantage of prevailing global wind systems to help the birds preserve energy, according to Carsten Egevang, from the Greenland Institute of Natural Resources [The Independent]. They also roughly double the distance that terns must fly, earning them this new record.
Not all tern migrations are created equal: The shortest in the study measured about 36,000 miles, the longest about 50,000. All in all, it adds up to a well-traveled lifetime. Terns can live on the long side of 30 years, and flying 44,000 miles every year for that length of time can add up to about 1.5 million miles, or about three lunar round trips.

The Planet Sand Castle: Upgrade Your Sandbox
Sir Isaac Newton saw an apple drop from a tree, and started contemplating gravity. Albert Einstein was riding in a street car, and Bern’s clock tower inspired the key to special relativity. Larry Page woke up in the middle of the night to scribble down a plan to download the Web, and Google was born. These “Eureka!” moments get the most fanfare, but Thomas Edison reminds us that “Genius is one percent inspiration and ninety-nine percent perspiration.”
The same can be said about new businesses and software applications: Even the best ideas require time, diligence, resources and a whole lot of work to succeed. If you’re a small business owner, you probably won’t make it very far by spending an hour a week executing your business plan. If you’re a developer, you won’t be able to code and test “the next Google” on an old Pentium II desktop in your closet.
While we can’t provide the inspiration, diligence or “whole lot of work” pieces of the puzzle, our new Sand Castle program can give you the resources and time you need to jumpstart your vision:
- A Dual Xeon server
- An Enterprise-class data center
- An Industry-leading network
- FREE for 12 Months.
The costs of rolling out new business plans and testing software can be prohibitive, especially in uncertain economic times. So think of Sand Castle as an economic stimulus for entrepreneurs and developers. We’re providing an online environment to help launch the next big Internet success.
The initial Sand Castle deployment includes up to 500 servers, and The Planet’s Chairman and CEO Doug Erwin looks at it like this: “With eight data centers, we’re in a position to offer a single server to 500 individuals who want to start their own businesses. These 500 servers could create 500 jobs, and then we’ll have taken one small step to pay it forward and be part of the solution.”
FREE Server Configurations
We consulted with many developers, and with their feedback, we set minimum server specs for this program:
- Dual Xeon 2.4, 2.8 or 3.2
- 1GB RAM
- 146 GB of HDD space
- 10Mbps Unmetered Bandwidth
- Operating System: CentOS 5
Eligibility
Are you a developer? Do you have a vision for a new application or service? Do you need help turning that vision into reality? If so, you’re perfect for the Sand Castle program.
Fill out the one-page signup form with your contact information and vision for a Sand Castle server. We expect demand to exceed our initial supply, so quantities may be limited, and not every application will be accepted. Take time to detail your plans and provide any applicable examples to give yourself the best chance.
If you’ve got the inspiration, it’s time for some perspiration. Visit the Sand Castle page to learn more and apply!
-Kevin
P.S. If you know of any friends who may be interested in the program, be sure to Tweet this, Digg it, email it or smoke-signal it.
