If you happen to have a few of hard drives laying around you can put them to good use with a Raspberry Pi by creating your own, very cheap NAS setup. My current setup is two 4TB hard drives and one 128GB hard drive, connected to my network and accessible from anywhere using the Raspberry Pi.

NSA mathematicians write brain teasers every month, can you solve any? When one thinks of institutions and places that house some of the brightest mathematical minds on the planet, one tends to think of companies like Google and academic institutions like MIT and Cal Tech.

NSA mathematicians write brain teasers every month, can you solve any?

But flying somewhat underneath the radar is the National Security Agency (NSA), the famed intelligence agency that was unwittingly thrust into the spotlight following Edward Snowden’s massive leak of classified NSA material.

New Theory Suggests Black Holes Are “Back Doors” to The Universe - Page 2 of 2 - Technofres. In a model following their theory, the new geometries would imply that the center point would be a very small spherical surface—consistent with that of a wormhole in a simple, rotational, electrically-charged black hole.

New Theory Suggests Black Holes Are “Back Doors” to The Universe - Page 2 of 2 - Technofres

“Our theory naturally resolves several problems in the interpretation of electrically-charged black holes”, says Gonzalo Olmo, one of the researchers from the Institute of Corpuscular Physics, Universitat de Valencia. “In the first instance we resolve the problem of the singularity, since there is a door at the center of the black hole, the wormhole, through which space and time can continue.” List of Essential Software for Ubuntu 16.04 LTS/Linux Mint 18.

Several major companies didn’t exist a decade ago. Making a solar energy conversion breakthrough with help from a ferroelectrics pioneer. Designers of solar cells may soon be setting their sights higher, as a discovery by a team of researchers has revealed a class of materials that could be better at converting sunlight into energy than those currently being used in solar arrays.

Their research shows how a material can be used to extract power from a small portion of the sunlight spectrum with a conversion efficiency that is above its theoretical maximum—a value called the Shockley-Queisser limit. Install DHCP Server in Ubuntu 16.04 - OSTechNix. DHCP, abbreviation of Dynamic Host Control Protocol, is a network protocol that assigns IP addresses automatically to client systems in the network. This reduces the tedious task of manually assigning IP addresses in a large network that has hundreds of systems.
