Marie Curie's Best Productivity Tricks
by Thorin Klosowski
Marie Curie was the first woman to win a Nobel Prize, and the only woman to win it in two different fields. She coined the term radioactivity, discovered radium (which eventually killed her), and managed to get things done regardless of the fact that the scientific world didn't always take her seriously. Here's how she did it.

Make Your Own LED Lightbulb!
by James Hobson
Do you like saving electricity? Who doesn’t!
Do you have a lot of LED light strips lying around, destined for a project that you never quite got around to? We’re guilty!
Do you have an old DC power adapter? Of course you do.
Do you love soldering? Duh.
Do you have a dead fluorescent light bulb sitting around? Maybe…
If so, here’s a quick and silly guide to making your very own LED light bulb! The result is a bit ghetto we admit, but quite functional. Perhaps it could be improved by adding a glass Christmas bobble to make it look a bit more like a regular light bulb. And if you’re ambitious enough you could throw a microprocessor in there and add wireless control to it as well … but let’s be honest, smart LED light bulbs are getting quite affordable these days. But hey, you’ve got to do something for entertainment!

RFID Reader Snoops Cards from 3 Feet Away
by Josh Marsh
Security researcher [Fran Brown] sent us this tip about his Tastic RFID Thief, which can stealthily snag the information off an RFID card at long range. If you’ve worked with passive RFID before, you know that most readers only work within inches of the card. In [Fran's] DEFCON talk this summer he calls it the “ass-grabbing method” of trying to get a hidden antenna close enough to a target’s wallet.
His solution takes an off-the-shelf high-powered reader, (such as the HID MaxiProx 5375), and makes it amazingly portable by embedding 12 AA batteries and a custom PCB using an Arduino Nano to interpret the reader’s output. When the reader sees a nearby card, the information is parsed through the Nano and the data is both sent to an LCD screen and stored to a .txt file on a removable microSD card for later retrieval.
There are two short videos after the break: a demonstration of the Tastic RFID Thief and a quick look at its guts. If you’re considering reproducing this tool and you’re picking your jaw off the floor over the price of the reader, you can always try building your own…

Bending it the right way: How LG and Samsung curved their phones differently
by Jason Inofuentes
In Korea, the rivalry between LG and Samsung is deep and fierce. The conglomerates clash in nearly every market, and their competitiveness often puts them in lockstep, even as they take surprising turns in product design. The latest fad is the move to curved displays on phones, and recent revelations show that there isn't yet industry consensus on how best to curve a phone.
The thing that often goes unnoticed about consumer tech fads like the curved phones we're seeing today (think 3D phones, giant phones, thin phones, phones with keyboards, and tablets with phones inside) is the amount of technical achievement required of the engineers that are behind them. The efforts to produce small 3D displays and cameras were driven by advances in image sensor processors and parallax screens. The thin phone craze was driven by shifts in the industrial design of phones and manufacturing techniques.
For the curved phone movement, the focus was initially on the development of flexible displays. The two biggest players in flexible display technology, LG and Samsung, have been demonstrating the potential of this tech for a long time. But screens aren't the biggest limiting factor in phone design, though. Nor is it cameras or silicon. It's the batteries.

It seems that Apple’s new iOS 7 is so advanced that it’s actually causing cybersickness — nausea caused by the combination of a high-resolution screen, the parallax effect on the Home screen, and the zooming in and out of apps. There hasn’t been an official response from Apple yet, but judging by comments from various…

Why The Space Shuttle Sucked
The Space Shuttle was long a symbol of US superiority in space, but were they successful, and were they worth it?

I saw the "ss" post from yesterday and wanted to share a far more powerful URL hack.
