6 Months of Security Links #2011
I’m a regular curator of daily links, and like to give overviews of my collection of curated links and posts. This is partly as there are some good sources and articles in here and as I am working on a research project which I started based on a number of books I read.
I’m sure you’ll find something interesting in the items below – there are some gems in the list – and I dare to hazard the guess you might learn something you wanted to know. 
Fraunhofer finding MP3 replacement #research
The Fraunhofer institute is trying to find a replacement for MP3, their current project is designed to last 10 years. Do we really need to have a replacement for MP3 sooner than that? The updates for MPEG came in closer succession, but were required because compression of video signals had such high priority.
You might say MP4, but it is actually MPEG4 part 14 and is not en encoding format, but a transport or container format. The encoding of the content is still done with MP3, AAC or other format.
I wonder what will be the trick to further compress the data, and whether it will be even more closely related to the MPEG4 standard.
Voices in my Head
I finally found out, from the article Crowd-Controlling: MEDUSA Ray Gun Puts Voices Inside Your Head, it’s all true. (Microwave ray gun controls crowds with noise) They can put voices in your head with “… a damned scary ray gun that uses the ‘microwave audio effect‘ to implant sounds and perhaps even specific messages inside people’s heads.“
“The microwave auditory effect, also known as the microwave hearing effect or the Frey effect, consists of audible clicks induced by pulsed/modulated microwave frequencies that are generated directly inside the human head without the need of any receiving electronic device.”1
This could be what happened to Lucille Ball:
“All of a sudden, my mouth started jumping. It wasn’t music this time, it was Morse code. It started softly, and then de-de-de-de-de-de. As soon as it started fading, I stopped the car and then started backing up until it was coming in full strength. DE-DE-DE-DE-DE-DE DE-DE-DE-DE!”2
