But a shocking claim made by one ransomware agent suggests there may be another motive: corporate sabotage. In an exchange with a security researcher pretending to be a victim, one ransomware agent claimed th

Scam Of The Week: Illegal Game of Thrones Download

There is a current email phishing scam going on where you get an official-looking email forwarded by your ISP, which states you have violated HBO copyrights and illegally downloaded Game of Thrones. The email has a link to a website where they say you can pay the fine. Don't fall for it. The message was sent by cybercriminals and they would get any money you pay.  In general, it's a bad idea to illegally download shows and movies for two reasons. Fir

Pokémon app

Pokémon app
  You have probably heard about the new Pokémon app. It's going viral and sends people on the street to catch these little virtual creatures.

How much RAM do you need, should you upgrade it, and will it speed up your PC? | ExtremeTech
How much RAM do you need? How much RAM you need in a system depends on what you intend to do with it, how long you intend to keep it, and whether or not you can upgrade your memory post-purchase. This last point is important, as many high-end laptops have eliminated user-upgradeable RAM in order to reduce system thickness by roughly six nanometers. Adding additional RAM to any laptop generally increases power consumption by a measurable (if small) amou

Starting a tech startup with C   — Startups, Wanderlust, and Life Hacking — Medium
Excellent article by James Perry I founded a new tech-startup called Signal Analytics with an old University friend, Fedor Dzjuba of Linnworks. We are building a modern, cloud-based version of OLAP cubes (multi-dimensional data storage and retrieval) using a propriety multi-dimensional database system. I am taking the lead on the technical side and I am most comfortable with C++ so decided to build our OLAP engine with it. I did originally build a prototyp

New year and same old me or maybe not
Most of us make resolutions for the new year and hope everything will change magically in this year but as the days pass on so does the enthusiasm and the new resolutions are left behind to solve the old issues first from the previous year. The same story is repeated for most of us year on year.

Multiplying teeth | EurekAlert! Science News

Researchers have found a way to -- literally -- multiply teeth. In mice, they were able to extract teeth germs -- groups of cells formed early in life that later develop into teeth, split them into two, and then implant the teeth into the mice's jaws, where they developed into two fully functional teeth.
