"You should be able to use the Web without fear that a criminal or state-sponsored actor is exploiting software bugs to infect your computer, steal secrets, or monitor your communications," writes Google security researcher Chris Evans. To help make that a reality, Google has put together a new team of researchers whose sole purpose is to find security flaws in software—any software—that's used on the Internet.

I've never once made a model rocket. I've always wanted to, but apart from "tube with explodey rocket part", I really didn't know where to start with designing. I recently found an open-source application that should help me with my lack of rocket science know-how: OpenRocket.

For end users, the complexity of such RPM dependency is hidden by package managers (e.g., yum or DNF) during package install/upgrade/removal process. However, if you are a sysadmin or a RPM maintainer, you need to be well-versed […]Continue reading...

IriTech has launched an Indiegogo project for an Android-based “Fidelys” smartwatch with iris recognition technology and a rotating-clicking bezel for I/O. The main draw of the Fidelys is its “military grade” iris recognition technology, which avoids the need for vulnerable, inconvenient, hard to remember passwords, says IriTech.

Another month, another few dozen patches to install -- it's never-ending. It's frustrating. Software coding tools supposedly have security built in by default. We have "safe" programming languages. We have programmers using SDL (security development lifecycle) coding tools and techniques.

We have companies spending billions of dollars to eliminate software bugs.
