medium While there have been plenty of terrifyingly realistic card skimmers in the past, we have bad news for you: the latest breed of skimmers are so thin that they’re inserted into the ATM, so you can’t see them at all.

Krebs on Security rounds up a handful or recent reports, and the news makes for grim reading. According to the European ATM Security Team, the latest ATM skimmers are in fact wafer-thin card reading devices, which are inserted up inside the card acceptance slots of cash machines. You can’t even see they’re there.

atms Of course, the good news is that these kinds of insert skimmers need to be able to record your PIN as you type it in—and that requires some secondary recording device. Usually that’s a keypad overlay, or a tiny camera, so there are still clues to look out for as you take out your cash.

So, the advice remains the same: if anything ever looks suspicious at an ATM, don’t use it. It’s just annoying that spotting the problem is getting more and more difficult. [EAST via Krebs on Security]

TED launches ‘TED-Ed’, hopes to make lessons worth sharing

tededbedhedred33 TED launches TED Ed, hopes to make lessons worth sharing

Who doesn’t love filling an idle hour with a good ol’ bit of TED? Now, the people behind those share-worthy ideas are bringing us TED-Ed: a new lesson-based YouTube channel. Aimed primarily at high-schoolers, the initiative invites teachers to submit their “best lesson” in a youthful mind-friendly ten minutes or less. If chosen, TED will ship out a “portable recording booth” — which look suspiciously like an iPad in a sound-absorbing flightcase. Once the knowledge has been preserved, it’s sent over to a team of animators to bring it to life. If you know a great teacher, or animator, you can also nominate them to the TED-Ed team if they’re too humble to put themselves forward. The TEDEducation YouTube channel is up and running right now, but the new original content won’t land until a dedicated site is launched next month. There’s a typically heartwarming and informative video about the project after the break.

What is Temporal Noise Reduction

Source: http://gizmodo.com/5891352/what-is-temporal-noise-reduction

medium What is Temporal Noise ReductionOne of the new iPad’s video features—along with 1080p recording and video stabilization—is temporal noise reduction. Apple claims it will improve the quality of footage in low-light conditions. OK, but what the hell is it?

It’s a clever technique…

There’s no getting around this: temporal noise reduction is tough to explain. That’s because it’s a complex process used to improve image and video rendering. This is very much a simplified explanation of what happens.

…that greatly reduces the noise of video…

When you record footage in low-light conditions, the resulting images are often noisy—speckled with pixelation that looks like a staticky TV screen. Why? Because there’s just not enough light hitting the sensor. In bright conditions, all the light provides a huge signal; noise—from electrical interference or imperfections in the detector—is still present, but it’s drowned out. In low light, the signals are much smaller which means that the noise is painfully apparent.

…by comparing what pixels actually move…

So, onto temporal noise reduction itself. Basically, it exploits the fact that with video there are two pools of data to use: each separate image, and the knowledge of how the frames change with time. Using that information, it’s possible to create an algorithm that can work out which pixels have changed between frames. But it’s also possible to work out which pixels are expected to change between frames. For instance, if a car’s moving from left to right in a frame, software can soon work out that pixels to the right should change dramatically.

…and guessing what is noise and what is actual detail…

By comparing what is expected to change between frames, and what actually does, it’s possible to make a very good educated guess as to which pixels are noisy and which aren’t. Then, the pixels that are deemed noisy can have a new value calculated for them based on their surrounding brothers.

…to make low-light video super-sharp.

So, the process manages to sneakily use data present in the video stream to attenuate the effects of noise and improve the image. It’s something that’s been used in 3D rendering for years, but it requires a fair amount of computational grunt. Clearly, the new iPad can handle that—and as a result, we’ll be fortunate enough to have better low-light video.

medium Google recently announced it was unifying its privacy policies and would be sharing the data it collects about users between all of its products, starting March 1st. That means your web searches and sites you visit will be combined with other Google products like Google Plus and YouTube. If you’d rather avoid that, the Electronic Frontier Foundation reminds us you can remove your Google search history and stop it from being recorded.

Turning off search history is one of the top Google settings you may already know about anyway if you didn’t want Google recording any sensitive searches (health, location, interests, religion, etc.), but with Google becoming more like AOL these days, now’s as good a time as any to check if you’ve got your web history paused or not.

If you’re not logged into Google already, log in. Then, go to https://google.com/history. Click “remove all Web History” and “OK”. Doing so will pause the recording of your searches going forward until you enable it again.

The Damning Data [Nexus One]

Source: http://feeds.gawker.com/~r/gizmodo/full/~3/BrVXM_LnhYs/the-nexus-ones-3g-problem-pt-ii-the-damning-data

500x 55613448 702dde3cadeb6e53ac2035202ea912a7.4b466647 scaled 01 The Damning Data [Nexus One]Google’s Nexus One support forums have been flooded with anecdotes about the phone’s poor 3G connectivity, so one user decided to follow up with some reasonably scientific tests. The conclusion? The Nexus One is kind of terrible at basic cellphonery!

The test was simple and limited, consisting of one dude, user WV, wandering in and out of his house, recording signal strength as measured in dBm and ASU with Android’s built-in metering app. Assuming the Nexus One is supposed to work like a normal cellphones—that is, it connects to 3G networks when they’re available and EDGE only when they’re not—something’s wrong.
500x screencap 2010 01 11 at 9.07.03 am The Damning Data [Nexus One]
Since the phone is obviously finding and receiving the cellular signals just fine, but not handling them as you’d expect, randomly flipping between the two—and evidently preferring EDGE most of the time—no matter how strong its signal is. This points to a software issue, not a hardware issue. That, and this:

OK. I found “Phone Info” screen through “Any Cut”. This looks like a screen not intended for average users. It clearly has settings that should not be messed with. However, it does have a pull down menu that was set to “WCDMA Preferred”. I changed this to “WCDMA Only”. The phone reset, and never a! gain saw the f’ing “E” on the signal indicator- ALL 3G. After about 1/2 hour of speed tests (150k – 800kbps) and google satellite map downloads (all definitely faster), I switched back to “WCDMA Preferred”. Guess what? After a few minutes, I was back on EDGE, even with a good signal. Switched back to “WCDMA Only”, and 3G it remains.

This doesn’t fully solve the problem, because as WV notes, if you fall out of T-Mobile’s 3G coverage area with EDGE disabled, you’re basically boned. But anyway, yes, this appears to be a software bug. Or, if you’re feeling conspiratorial today, like WV, a software feature:

My concern is whether T-mobile is being sneaky about this and purposefully dumbing down the 3G to Edge to reduce cell frequency congestion and/or their back-end network congestion.

I’m not sure I want to draw that nexus (haw?) quite yet, since the issue was first brought to light by comparing the Nexus One’s 3G/EDGE handling to other T-Mobile 3G Android handsets, and those, despite having the same data-sucking potential as the Google Phone, haven’t been throttled in any way. While Google and T-Mobile say they’re “investigating,” the evidence keeps mounting and the question looms larger: what’s really wrong with the Nexus One’s 3G? [Google Nexus One Support Forums]
