Does Your Password Pass Muster? Password Strength Meters Not All Created Equal

Does Your Password Pass Muster? Password Strength Meters Not All Created Equal

“Create a password” is a prompt familiar to anyone who has tried to buy a book from Amazon or register for a Google account. Equally familiar is that red / yellow / green bar that rates the new password’s strength. But when those meters give the go-ahead to passwords like Password1+, their effectiveness is called [...]

Mobile Battery Life can be Prolonged with System Settings

Mobile Battery Life can be Prolonged with System Settings

By using crowdsourced measurements researchers explain the energy impact of smartphone system settings, and their results show how to improve a mobile device’s battery lifetime by adjusting the settings. The NODES research group from University of Helsinki, Finland, has studied how the impact of different settings on battery lifetime can be estimated using crowdsourced measurements [...]

Computer Programming: System Automatically Finds Common Type of Programming Bug

Computer Programming: System Automatically Finds Common Type of Programming Bug

Integer overflows are one of the most common bugs in computer programs — not only causing programs to crash but, even worse, potentially offering points of attack for malicious hackers. Computer scientists have devised a battery of techniques to identify them, but all have drawbacks. This month, at the Association for Computing Machinery’s International Conference [...]

New Approach Uses ‘Twisted Light’ to Increase Efficiency of Quantum Cryptography Systems

New Approach Uses ‘Twisted Light’ to Increase Efficiency of Quantum Cryptography Systems

Researchers at the University of Rochester and their collaborators have developed a way to transfer 2.05 bits per photon by using “twisted light.” This remarkable achievement is possible because the researchers used the orbital angular momentum of the photons to encode information, rather than the more commonly used polarization of light. The new approach doubles [...]

Mobile Quarantine Station for Malicious Android Apps

Mobile Quarantine Station for Malicious Android Apps

The attacks were perfidious: In February this year, the Czech IT security company Avast declared that it had identified several malicious game apps for mobile phones in the Google Play Store – ones that would only become criminally active on the device after several weeks. Then the affected smartphones or tablet computers would suddenly take [...]

Nano Piano’s Lullaby Could Mean Storage Breakthrough

Nano Piano’s Lullaby Could Mean Storage Breakthrough

Researchers from the University of Illinois at Urbana-Champaign have demonstrated the first-ever recording of optically encoded audio onto a non-magnetic plasmonic nanostructure, opening the door to multiple uses in informational processing and archival storage.   “The chip’s dimensions are roughly equivalent to the thickness of human hair,” explained Kimani Toussaint, an associate professor of mechanical [...]

Computer Scientists Simplify Parallel Programming

Computer Scientists Simplify Parallel Programming

Modern software takes computational speed for granted. But modern microprocessors can only speed up by increasing the number of cores. To take full advantage of multiple cores, software developers have to arrange their code in such a way that it is executable in parallel – an error-prone and expensive task. Computer scientists from Saarland University [...]

How to Manage and Orchestrate Various Kinds of Clouds and Data Centers Easily and Effectively

How to Manage and Orchestrate Various Kinds of Clouds and Data Centers Easily and Effectively

An Interview with Alex Henthorn-Iwane of QualiSystems As we have more ways to manage our ICT infrastructures, from bare metal to virtual, doing so becomes more complex and labor intensive. Manual processes tend to be error prone and not scalable with rapidly multiplying and changing computing resources. We need automated systems to manage various kinds [...]

Data Driven Discoveries: Imagine Smart Cities with Thousands of Strategically Placed Sensors

Data Driven Discoveries: Imagine Smart Cities with Thousands of Strategically Placed Sensors

As urban populations increase, so too does the complexity involved in maintaining basic services like clean water and emergency services. But one of the biggest barriers to making cities “smarter” — for example, comprehensively monitoring sources of waterway pollutants in real time — is quick and easy access to data.   Future scenarios like these [...]
