Software-defined radio (SDR) is a radio communication system where components that have been traditionally implemented in hardware (e.g. mixers, filters, amplifiers, modulators/demodulators, detectors, etc.) are instead implemented by means of software on a personal computer or embedded system. Experimenting with software defined radio used to be expensive, but now it is cheap. Nowadays it is →
This is good stuff! Building your own SDR-based Passive Radar on a Shoestring http://hackaday.com/2015/06/05/building-your-own-sdr-based-passive-radar-on-a-shoestring/ two $8 RTL software defined radio dongles and two log-periodic antennas. And get this, the radar system you’re going to build works by listening for existing transmissions that bounce off the targets being measured! A passive radar is a special type →

http://www.zdnet.com/article/sun-set-oracle-closes-down-last-sun-product-lines/ Officially, Oraclehasn’t said a thing. As many as 2,500 Oracle, former Sun, employees have been laid off. Good bye, SPARC. Good bye, Solaris. Your day is done. None of this is a real surprise. Indeed, you’d be hard pressed to find anything that went right with Oracle’s $7.2 billion purchase of Sun. Oracle buying Sun was a →

It can cause need to rethink the current sloppy security practices on many companies – the identifying data many companies use has now leaked out. The private data of 143 million Equifax “customers” is now available for download. Have no doubt: →
https://www.roadtovr.com/5-google-arcore-experiments-inject-magic-everyday-life/ Google just released a preview version of ARCore for Android as the company’s answer to Apple’s ARKit. Since ARKit was released a few months ago, we’ve seen a bevy of really cool experiments and potential apps to come from developers from all over the world, but now it’s ARCore’s turn to shine. →
