Backupninja allows you to coordinate system backup by dropping a few simple configuration files into /etc/backup.d/. Most programs you might use for making backups don't have their own configuration file format. Backupninja provides a centralized way to configure and schedule many different backup utilities. It allows for secure, remote, incremental filesytem backup (via rdiff-backup), compressed incremental data, backup system and hardware info, encrypted remote backups (via duplicity), safe backup of MySQL/PostgreSQL databases, subversion or trac repositories, burn CD/DVDs or create ISOs, incremental rsync with hardlinking.

With FPM, you can specify dependencies, architecture, maintainer, etc. All from a simple command line, and never forcing you to learn the pain and suffering that can come with rpm spec files or debian package building.

As of November last year, the city saved more than €11.7 million (US$16.1 million) because of the switch. More recent figures were not immediately available, but cost savings were not the only goal of the operation. It was also done to be less dependent on manufacturers, product cycles and proprietary OSes, the council said Thursday.

Speaking at the keynote LinuxCon panel this year, Linus Torvalds, who created the open-source Linux operating system 22 years ago, revealed that the government had approached him about installing a backdoor into system’s structure. Linux is the preferred operating system for the privacy conscious infosec community.

The idea we had was to build an “unattended self-deploying” instance of Kali Linux that would install itself on a target machine along with a customized configuration requiring no user input whatsoever. On reboot after the installation completes, Kali would automagically connect back to the attacker using a reverse OpenVPN connection. The VPN setup would then allow the attacker to bridge the remote and local networks as well as have access to a full suite of penetration testing tools on the target network.

Ever wanted a development kit that flies? Well now you can! The Crazyflie is an open source nano quadcopter kit designed for flexible development and hacking. It's among the smallest in the world, weighing only 19 grams and measuring 9 cm motor to motor.

Until recently it has been assumed that OS virtualization is the only path to provide appropriate isolation for applications running on a server. These assumptions are quickly becoming dated, thanks to recent underlying improvements to how the Linux kernel can now manage isolation between applications. § Containers now can be used as an alternative to OS-level virtualization to run multiple isolated systems on a single host. Containers within a single operating system are much more efficient, and because of this efficiency, they will underpin the future of the cloud infrastructure industry in place of VM architecture.

KSP is a game where the players create and manage their own space program. Build spacecraft, fly them, and try to help the Kerbals to fulfill their ultimate mission of conquering space. The game is currently under heavy development. This means the game will be improved on a regular basis, so be sure to check back for new updates. Right now, KSP is in Sandbox Complete state, but we want you to try it out and have fun with it. The first versions are free to download and play, and will remain so forever.

The TTY subsystem is central to the design of Linux, and UNIX in general. Unfortunately, its importance is often overlooked, and it is difficult to find good introductory articles about it. I believe that a basic understanding of TTYs in Linux is essential for the developer and the advanced user. Beware, though: What you are about to see is not particularly elegant. In fact, the TTY subsystem — while quite functional from a user's point of view — is a twisty little mess of special cases. To understand how this came to be, we have to go back in time.

Docker encapsulates heterogeneous payloads in Standard Containers, and runs them on any server with strong guarantees of isolation and repeatability. It is a great building block for automating distributed systems: large-scale web deployments, database clusters, continuous deployment systems, private PaaS, service-oriented architectures, etc.
