Researchers Develop Purely Optical Cloaking

Technologies for making things invisible is always interesting. There are active and passive technologies that have been tried for this. My earlier posting Mercedes uses LEDs to create invisible car showed and active technology that used camera + huge LED display to make invisibility effect. Yesterday I saw a new interesting passive one. Researchers Develop

Spintronics

Spintronics is an emerging technology exploiting both the intrinsic spin of the electron and its associated magnetic moment, in addition to its fundamental electronic charge, in solid-state devices. Spintronics differs from the older magnetoelectronics, in that the spins are not only manipulated by magnetic fields, but also by electrical fields. Spintronics emerged from discoveries in

Shellshock Bash Vulnerability

Unix/Linux Bash: Critical security hole uncovered and it seems to be all around in the news. The claim is that popular Linux and Unix shell has a serious security problem that means real trouble for many web servers. Let’s check the facts fist, is this real from some reliable source. There is Vulnerability Summary for

Circuit design software list

What is the best free or cheap electronics design software? It is hard to say in this ever changing field. I some time ago mentioned some software examples in Top Free Electronics Design Tools posting and you can find a long comparison list at Wikipedia Comparison of EDA software page. For the circuit design I would
