TrueCrypt — Learn the Art of Encryption

Filed under

Many commercial encryption products can protect files, folders and partitions. Probably the most discussed is “Bitlocker”, which is bundled free with MS Windows 7 Ultimate. And if you have ever wondered if there is open source encryption software — there is and it’s called TrueCrypt.

As mentioned on, it is a software system to establish and maintain an on-the-fly-encrypted volume (data storage device). On-the-fly implies that data is automatically encrypted right before it is saved, and decrypted right after it is read, without user intervention. No data stored on an encrypted volume can be decrypted without the correct password/keyfile(s) or correct encryption keys. The entire file system is encrypted.

Files can be copied to and from a mounted TrueCrypt volume just like with any normal disk (for example, by simple drag-and-drop operations). The software works as expected, is simple, and has a GUI for ease of use.

More OpenSUSE Leap Linux Kernel Benchmarks

Earlier this week I posted a number of openSUSE Leap benchmarks of their different kernels: debug, default, desktop, and vanilla. Here's some follow-up tests with more results from comparing the openSUSE 42.1 Leap Beta kernel builds. The tests are very similar to the article earlier this week, just with many more data-points now after seeing the performance differences from the initial test suite. Read more

LinuxCon 2015 Report: Dirk Hohndel Chats with Linus Torvalds

For many LinuxCon attendees, one of the biggest event highlights is the opportunity to rub elbows with the people who actually write the Linux code. The only thing that can top that? Hearing from Linus Torvalds himself, the man who created it 24 years ago and still writes the code to this day. Read more

Open Network Linux Simplifies Open Compute Project Switch Configuration

Big Switch Networks, Facebook and NTT, announced today that they have come together to create a unified operating system for the Open Compute Project‘s (OCP) open source networking switch called Open Network Linux. The project is designed to help companies, whether web scale-type companies like Facebook or others looking to take advantage of the Open Compute Project’s open source switches, to use the platform as a base to configure the switches in a way that makes sense to them.

Would the Internet Exist without Linux? Yes. Without Open Source? No

Would the Internet exist if Linux did not? A video out this week from the Linux Foundation, which has launched a new campaign to promote open source, says no. History says yes. The minute-long video is the first in a new series the Linux Foundation has created called "A World Without Linux." The series "flips reality on its head to illustrate in an entertaining fashion just how pervasive Linux is today," according to a Linux Foundation representative. Read more
