‘Space-Time Cloak’ to Conceal Events

The study, by researchers from Imperial College London, involves a new class of materials called metamaterials, which can be artificially engineered to distort light or sound waves. With conventional materials, light typically travels along a straight line, but with metamaterials, scientists can exploit a wealth of additional flexibility to create undetectable blind spots. By deflecting certain parts of the electromagnetic […]

EFF Brief: “Privacy” Protections for Corporations Undermines Government Transparency

EFF and a coalition of public interest groups urged the U.S. Supreme Court in an amicus brief Tuesday to reject so-called “privacy” protections for corporate entities under the Freedom of Information Act (FOIA). The case, Federal Communications Commission v. AT&T, started when the company tried to block disclosure of records about its participation in the federal government’s E-Rate program. AT&T, […]

The Case Against COICA

In September, digital rights advocates and Internet engineers helped to delay the Combatting Online Infringement and Counterfeits Act (COICA), a terrible bill that would have allowed the Attorney General to censor the Internet in the name of copyright enforcement. Now that the November elections are over, COICA is back on the Senate Judiciary Committee schedule for markup this Thursday and […]

The FBI and Service Provider Wiretapping, or What’s In Your Wallet?

The FBI’s apparent desire to require all communications service providers to design a means for law enforcement to access encrypted communications in plain text could have negative effects on personal privacy and industry innovation. Computer scientists, however, concentrate on a different concern: the danger that such design mandates could harm cybersecurity.  In an ironic twist, the FBI’s well-intentioned attempt to […]

In Data Portability Deathmatch, Users Lose Out

In the last few weeks, Facebook and Google have been engaging in a public tussle over an issue that is near and dear to EFF’s heart: data portability. The crux of the issue is that when you sign up for Facebook, you can find your Gmail contacts or invite them to join the social networking service with a few quick […]

The Spoils of the Android Wars

I have poor impulse control. Though I manage to avoid most major vices, including all the illegal ones, I do have a gigantic closet full of formerly cutting-edge tech gadgets that I bought. My collection of video games for every console on the market draws players from all over the ‘hood here in Boulder, Colorado. But my living room and […]

An Open Source Toolkit for Your Small Business

Whether your small business has been around for years or you’re just starting out, it simply makes good sense to use open source software for everything from managing your office network to putting together slide decks for your next client presentation. Open source software is inexpensive (and often free!), secure, and easy to customize to the unique needs of your […]

New Standard Proposed for Supercomputing

A new supercomputer rating system will be released by an international team led by Sandia National Laboratories at the Supercomputing Conference 2010 in New Orleans on Nov. 17. The rating system, Graph500, tests supercomputers for their skill in analyzing large, graph-based structures that link the huge numbers of data points present in biological, social and security problems, among other areas.

‘Racetrack’ Magnetic Memory Could Make Computer Memory 100,000 Times Faster

Imagine a computer equipped with shock-proof memory that’s 100,000 times faster and consumes less power than current hard disks. EPFL Professor Mathias Kläui is working on a new kind of “Racetrack” memory, a high-volume, ultra-rapid non-volatile read-write magnetic memory that may soon make such a device possible. Annoyed by how long it took his computer to boot up, Kläui began […]

EU laws already protect the open Internet: let’s enforce them now to stop the rise of the ‘unternets’

There’s a sign in a street near the Skype office which reads: I can’t understand why people are afraid of new ideas. I’m frightened of the old ones. I like that. It is actually indicative of some of the things we witness in the world of Internet access today: a desire by some to change the Internet to lots of […]

Linux Mint 10 manual disk partitioning guide

Linux Mint 10, aka Julia, is the latest stable release of Linux Mint, a desktop-oriented distribution based on Ubuntu. Just like earlier releases of Linux Mint, Linux Mint 10 is installed on a partitioning scheme with just one root file system, no separate /boot and /home partitions. While this may seem convenient, it is not the recommended method of partitioning […]

How to enable auto-login and create a guest user account on Fedora 14

How to enable auto-login and create a guest user account on Fedora 14

Fedora is one of very few distributions that does not have the auto-login feature in its graphical user management tool. Auto-login allows the system to automatically login a user without requesting authentication, that is, it enables password-less logins. While it is a very convenient feature, it is a security risk. Why? Because if it is enabled, any person with (physical) […]

Three New Android Vulnerabilities Released

Smartphone security has become a popular topic amongst security researchers, with three new vulnerabilities released in the last two weeks alone. Speakers at BlackHat Abu Dhabi, HouSecCon, and Intel’s Annual Security Conference have released new vulnerabilities in Android that allow attackers to execute arbitrary code or install apps without user intervention. Last week, Alert Logic released exploit code that targets […]

Updated Software Uses Combination Testing to Catch Bugs Fast and Easy

Researchers at the National Institute of Standards and Technology (NIST) have released an updated version of a computer system testing tool that can cut costs by more efficiently finding flaws. A tutorial on using the tool accompanies the new release. Catching software “bugs” before a program is released enhances computer security because hackers often exploit these flaws to introduce malware, […]
