If you are running windows based computer you’ll know, like many others than after a while your system will in doubt start running slow. Most people will restart their computer to remove and idle processes. But if there’s a simpler way, why restart every time windows decides it doesn’t like you today?
1. Right click on an empty spot on your desktop and select New - Shortcut.
2. Type %windir%\system32\rundll32.exe advapi32.dll,ProcessIdleTasks in the box.
3. Click Next.
4. Give your shortcut a nice name like “Clear Memory”.
5. Click Finish and you’re done.
Now whenever your computer starts running slow click this shortcut to clear out your memory and get your computer running at a normal pace again.

Scientists Invent 30 Year Continuous Power Laptop Battery
(For full text with comments please click on the title)
Your next laptop could have a continuous power battery that lasts for 30 years without a single recharge thanks to work being funded by the U.S. Air Force Research Laboratory. The breakthrough betavoltaic power cells are constructed from semiconductors and use radioisotopes as the energy source. As the radioactive material decays it emits beta particles that transform into electric power capable of fueling an electrical device like a laptop for years.
Although betavoltaic batteries sound Nuclear they’re not, they’re neither use fission/fusion or chemical processes to produce energy and so (do not produce any radioactive or hazardous waste). Betavoltaics generate power when an electron strikes a particular interface between two layers of material. The Process uses beta electron emissions that occur when a neutron decays into a proton which causes a forward bias in the semiconductor. This makes the betavoltaic cell a forward bias diode of sorts, similar in some respects to a photovoltaic (solar) cell. Electrons scatter out of their normal orbits in the semiconductor and into the circuit creating a usable electric current.
The profile of the batteries can be quite small and thin, a porous silicon material is used to collect the hydrogen isotope tritium which is generated in the process. The reaction is non-thermal which means laptops and other small devices like mobile phones will run much cooler than with traditional lithium-ion power batteries. The reason the battery lasts so long is that neutron beta-decay into protons is the world's most concentrated source of electricity, truly demonstrating Einstein’s theory E=MC2.
The best part about these cells are when they eventually run out of power they are totally inert and non-toxic, so environmentalists need not fear these high tech scientific wonder batteries. If all goes well plans are for these cells to reach store shelves in about 2 to 3 years.
