Managing devices in Linux  There are many interesting features of the Linux directory structure. This article covers some fascinating aspects of the /dev directory.  Device files are also known as device special files. Device files are employed to provide the operating system and users an interface to the devices that they represent. All Linux device files are located in the

Millions of high-security crypto keys crippled by newly discovered flaw | Ars Technica  A crippling flaw in a widely used code library has fatally undermined the security of millions of encryption keys used in some of the highest-stakes settings, including national identity cards, software- and application-signing, and trusted platform modules protecting government and corporate computers. The weakness allows attackers to calculate the private portion of any vulnerable key

Severe flaw in WPA2 protocol leaves Wi-Fi traffic open to eavesdropping | Ars Technica An air of unease set into the security circles on Sunday as they prepared for the disclosure of high-severe vulnerabilities in the Wi-Fi Protected Access II protocol that make it possible for attackers to eavesdrop Wi-Fi traffic passing between computers and access points.  There is a proof-of-concept exploit called KRACK, short for Key Reinstallation Attacks. KRACK

Physicists Will Be Announcing An “Unprecedented Discovery” On Monday – Here’s How To Watch Live | IFLScience  In the space of just a few weeks, the LIGO and VIRGO collaborations have announced the fourth detection of gravitational waves and three of their most prominent physicists received a Nobel Prize for their work. And on Monday they will announce something new. 

Troy Hunt: What Would It Look Like If We Put Warnings on IoT Devices Like We Do Cigarette Packets?  So how would warning labels on IoT devices that have had serious security vulnerabilities look?   Hilarious and also so needed. “Intrusions can occur anywhere”…  Or maybe it doesn’t need to be tech/legalspeak. WARNING! This connects to the INTERNET and BAD THINGS may happen!

Smartphone Cameras Peek Around Corners by Analyzing Patterns of Light – IEEE Spectrum  Magically seeing around corners to spot moving people or objects may not rank first in most people’s superhero daydreams. But MIT researchers have shown how they could someday bestow that superpower upon anyone with a smartphone. Their secret to peeking around corners is detecting slight differences in light patterns reflected from moving objects or

Why Solar Microgrids May Fall Short in Replacing the Caribbean’s Devastated Power Systems – IEEE Spectrum  After the destruction inflicted across the Caribbean by hurricanes Harvey, Irma, and Maria, renewable energy advocates are calling for a rethink of the region’s devastated power systems. Renewables advocates argue that the island grids should leapfrog into the future by interconnecting hundreds or thousands of self-sufficient solar microgrids. Some power system experts, however, say the solar-plus-batteries

Ten Years of the LilyPad Arduino  The LilyPad Arduino was designed for e-textiles and wearables projects. It along with an accompanying collection of power supplies, sensors, and actuators share unique design with large conductive sew tabs around the edges. These allow the boards to be sewn onto fabrics, and soft surfaces, using conductive thread to build working circuits. Essentially it’s a specially

Friday the 13th

Today is a special day:  Friday the 13th is considered an unlucky day in Western superstition. It occurs when the 13th day of the month in the Gregorian calendar falls on a Friday, which can be the case at least once every year, and up to three times a year. The superstition surrounding this day may have arisen in the Middle

Friday Fun: 17 Japanese mascots getting stuck in things  Japan has hundreds of mascots, or Yuru-chara, to promote companies, local culture, history or produce. It’s not an easy life, especially if you’re using public transport… but you might find some of the pictures of those occasions funny.
