Linux-based clock radio

An open-source Linux-based clock radio from SpriteMods: Ofcourse, a nice PCB with a powerful processor and a nice display only is scrap without the software: especially in this case, it pretty much defines what the device does. While developing the hardware, I already had made the decision to go with Linux and OpenWRT as an OS, as that’s […]

Monitoring Android traffic with Wireshark

Ever wonder what data is being sent out by your Android device? Here’s a post from LinuxJournal outlining how to monitor your device’s WiFi traffic.

Linux security tip: moving your /boot partition to removable media

Today threats to your data can come from many quadrants. It’s not enough to protect against malicious online attacks; there’s the very real threat of government confiscating and examining the electronic devices carried by international travelers, and even planting spyware. In this post from “The Doctor”, we’re shown one way to mitigate this threat, which […]

Analysing 433 Mhz transmitters with RTL-SDR

Yashin has posted this tutorial at ArcanumX demonstrating how to read and decode 433 MHz digital data transmissions. “I intend to demonstrate how the RTL-SDR can be used to sniff 433 Mhz transmitters. These are pretty cheap and can be found in a lot of appliances including alarm sensors. This post is also intended to […]

“The Linux Foundation, the nonprofit organization dedicated to accelerating the growth of Linux and collaborative development, has announced it is building a Massive Open Online Course (MOOC) program with edX, the nonprofit online learning platform launched in 2012 by Harvard University and Massachusetts Institute of Technology (MIT). More than 31 universities have partnered with edX […]

Hak5 video: quadcopter with WiFi enabled Linux computer and RTL-SDR

What happens when you send up a quadcopter equipped with a Linux box, WiFi and an RTL-SDR dongle? Darren and company from Hak5 decided to find out. Their project used the SDR to receive ADS-B signals from aircraft hundreds of miles away. The Hak5 team took a quadcopter up on top of a high mountain, […]

Tutorial: solid state drives and Linux

Solid state drives (SSD) are gaining in popularity, particularly as components costs and machine form factors continue to shrink. In this article from Linux Journal online magazine, Brian Trapp gives an in depth presentation on the current state of SSD’s and their advantages and disadvantages in various Linux related operations.

Advanced Hard Drive Caching Techniques

Petros Koutoupis at Linux Journal posted detailed information regarding hard drive caching techniques. Users of traditional hard drives who’ve been considering a switch to a solid state drive (SSD) should find this particularly interesting. Petros describes, Even today, the consumer SSD cannot compare to the capacities provided by the magnetic hard disk drive (or HDD), […]

SkyJack open source drone hacking project

SamyKamkar developed this seriously cool project to wrest control of civilian drones away from their owners. SkyJack is a drone engineered to autonomously seek out, hack, and wirelessly take full control over any other drones within wireless or flying distance, creating an army of zombie drones under your control. Using a Parrot AR.Drone 2, a […]

Decoding FLEX pagers using RTL-SDR and Linux

Superkuh2 demonstrates how to decode FLEX pager radio traffic. He uses gr-pager and zarya’s implementation of it on the Linux platform with the RTL-SDR dongle. This script runs at a 250 KS/s sample rate and decodes one 12.5 KHz channel only. Internally it uses gnuradio’s optfir to generate low pass taps stopping at 12.5 KHz […]

FreeMat: another MATLAB replacement

MATLAB is software tool providing a high-level language and interactive environment for numerical computation, visualization, and programming.
