Submission + - Facebook Admits It Doesn't Know How Mobile Works (

deltaromeo writes: As Facebook moves inexorably toward its much-anticipated initial public offering, attention has been focused on all kinds of things about the giant network with the $100 billion potential market valuation—including the earth-shattering fact that Chief Executive Officer Mark Zuckerberg insists on wearing a hoodie during his meetings with Wall Street bankers and analysts. But what investors should be more focused on is the problem Facebook highlights in the most recent amendment to its S-1 securities filing: namely, that its mobile business is noticeably light on advertising revenue and that the company isn’t exactly sure how (or whether) it can fix that.

Submission + - Researchers Use Stem Cells To Grow New Teeth (

bonch writes: Scientists from the College of Dental Medicine at Nova Southeastern University have successfully grown new teeth from stem cells. After extracting stem cells from existing oral tissue, the cells are molded into the shape of a tooth using a polymer scaffold. Using this method, teeth have already been successfully grown in mice and monkeys, with human clinical trials under way.

Submission + - Tech for Small Library Automation? 1

Kozz writes: I've recently been tapped as "the tech guy" at my church where a group familiar with library automation wants to get digital with the relatively small catalog. Right now all the materials are simply on shelves, and people take an item down, fill out the paper card and drop it into a box, and we hope that people correctly calculate their own due dates and return the materials. We had a card catalog, but it went largely unused. We're looking for a complete solution for both administration and self-checkout; label printing, checkout receipts, and so on. Have any Slashdot readers found yourself in this position, and do you have recommendations based on your experiences?

Submission + - Deadly fungus lives in most dishwashers (

An anonymous reader writes: A new study in the journal Fungal Biology found that a once-rare and potentially deadly fungus lives in more than half of all dishwashers — and survives on the "clean" dishes.

Submission + - Jellyfish Invasions Force Shutdowns at 3 Nukes (

mdsolar writes: "A nuclear power plant on the coast of Israel was forced to shut down this week when its seawater cooling system became clogged with jellyfish. A similar incident temporarily disabled two nuclear reactors at the Torness power station on the Scottish coast last week. A week before, a reactor in Shimane, Japan was crippled by yet another jellyfish infiltration."

Submission + - The professor's wife and her amazon antics (

crimeandpunishment writes: What happens when an anonymous reviewer on Amazon is unmasked? When that reviewer....who wrote some pretty nasty things in book reviews....turns out to be the WIFE of an author and college turns into a pretty juicy scandal in the academic world.

ATMs In Antarctica Screenshot-sm 26

Widgett writes "After hearing about the ATMs in Antarctica, I got curious. So I pinged Wells Fargo and got an interview with one of their VPs. The end result is a story about how one services machines at the end of the world, plus — and most importantly — what are the service fees like?"

Submission + - LED wiring for new construction? 1

overshoot writes: With any luck I'll be building a new house in the next year. Rather than wire it for 19th century lighting, I figured it was about time to plan ahead for LED illumination, complete with designed-in addressable color controls and all that. Which is all well and good, but the current house was preplanned for LAN, too — and I totally missed the boat on LAN wiring standards. I'd rather not repeat that little bit of history, but I haven't found any standards in the pipeline for 21st century home lighting connections.

Anyone have suggestions?

Comment Re:Bandwidth Allies? (Score 1) 220

Oh I wish I had mod points right now - this is VERY true. AT&T's network is painfully slow in most markets (luckily, my primary market is pretty good, but I frequent others where it is almost completely unusable). 3G data is pointless if you have zero capacity in your back-haul to the backbone...I can see this only as fodder to raise rates and cry fowl against the voip companies in a few months...


Submission + - HS Student Isolates Polystyrene-eating Microbe (

cmholm writes: "Although I had for years assumed that plastics eventually biodegrade, my recent reading of Weisman's The World Without Us reminded me that just because garbage has broken down into pieces that I can't see doesn't mean it isn't still polluting the biosphere. Weisman's book suggests that we're pretty much stuck with most plastics until something evolves to eat them. Perhaps we just need to introduce the diner to the dinner. A Waterloo, Ontario teen's 2008 science fair experiment found polystyrene's match in the team of the relatively uncommon Sphingomonas and Pseudomonas bacterias. At 37 degrees and optimal bacterial concentration, with a bit of sodium acetate thrown in, Burd achieved 43 per cent degradation within six weeks, rather than thousands of years."

Submission + - SSL Flaw by (Browser) Design? (

Eddy Nigg writes: "A while ago, the two security "white hats" Alexander Sotirov and Mike Zusman announced that they are going to publish a tool for exploiting EV SSL secured sites at the Black Hat Security Conference at the end of this month. Some sites reported the alleged attack on EV SSL secured sites as a means to prove that Extended Validation (EV) digital certificates aren't any more secure than regular SSL certificates. That's obviously an interesting claim since EV certificates traditionally costs quite a lot more than those that don't turn the address bar of the browsers green.

But is it really an attack on EV SSL secured sites? Does it indicate that such web sites aren't any more secure than others?"


Submission + - Cuba strikes back at Free Software 3

An anonymous reader writes: A week ago, the largest Cuban support group vanished from the net. Though the site had been "closed for maintenance" for several months, there was a very active mailing list hosted on that server. The mailing list, named "Linux-l", was the living history of the Free Software Movement in Cuba, and its archives were the best on-line resource that most Cubans could access. Recently, and for fear of government intervention, an spin-off list was created, were the hottest topics were addressed (like the necessity and feasibility of national connectivity for the development of free software), out of the reach of the Government, but also out of reach for the majority of the subscribers. Apparently, it may have not been enough. The blackout, blamed at first to the bureaucracy, is taking too long to be solved, and government officials (or list administrators) haven't yet made any statement. A more likely explanation seems to be that the government may have realized that the Free Software movement will not get along with the censorship they desire.

A call to the Cuban subscribers that may read this: publish your Linux-l mailbox somewhere, so at least part of the history is preserved. To the list administrators, try to find backups and start anew. To the government: we've been working for you, for free and unconditionally, since before you decided to recognize us. Correct this situation so we can keep working for you. Ignore it, and you will be alienating the biggest on-line forum of supporters you ever had. And for the rest of you, there may be something of interest still left at the Internet Archive.

Submission + - Scientists use MRI machines to read minds... kinda

NigelTheFrog writes: Researchers in England have used fMRI to map the activity in volunteers' hippocampi (hippocampuses?). From these scans, they could pinpoint exactly wher they were in a virtual reality landscape.

"Specific parts of each participant's hippocampus were active after that person had navigated to particular places in the room. A few practice rounds provided fodder for creating algorithms for each participant that correlated different brain activity patterns with different virtual locations. The algorithms, the team found, could in turn "predict" new virtual locations, not those used during practice rounds, based on each person's pattern of brain activity."

Submission + - Stores Reps Push Unnecessary Recovery Discs (

Ed Albro, PC World writes: "At PC World, we've got a story today on salespeople at Best Buy and Circuit City pushing consumers to pay the stores' technicians to create recovery discs for their new laptops. Recovery discs are important to have, of course, but the fact is that they're easy to make yourself. Or you can get them from the manufacturer of your PC, often for half of what Best Buy and Circuit City charge you. The salespeople often tell you that you can buy from the manufacturer — but they claim you'll pay twice as much as the stores charge."
