Detecting those pesky neutrinos with Fermilab’s 14,000 ton NOvA detector

Neutrinos are very small particles, smaller than the electrons and they can travel through led for 2 years before hitting an led atom. Neutrinos have no charge and leave no traces, so they are hard to trap. Fermilab, IL, USA is generating neutrinos and shooting them 500 miles away, straight through the Earth crust to […]

How does the computer draw curved lines? It’s more complicated than you think

Cubic Bezier Curves – Under the Hood from Peter Nowell on Vimeo. I never knew how a computer draws curved lines, but now that I have seen it, I can say that it is an incredible process. What about games, where you have tons of polygons, about animations and so on? Man, do these computers […]

What is the difference between anti-virus and anti-malware

As Linus, from TechQuickie, put it: both work int he same way as they fight viruses, but its the time scale they work on that matters.

The display would show tree, branches and leaves in order to help the operator run the entire facility with only a couple of touches. The touchscreen was developed at CERN in 1977 by Bent Stumpe, […]

The best AMD APU upgrade? A dedicated graphics card. I LOL’d

Not much to say about this, actually. APU processors from AMD do a fine job in using those processors as graphics cards too, but they are weak. You may use a R7 270x in dual mode with the APU, but it won’t help too much. The answer is always: dedicated graphics card. This is why […]
