The 21 Laws of Computer

21 LAWS OF COMPUTER The following are some Laws governing computer as provided by some computer scientists over time. Amdahl’s Law: The speed-up achievable on a parallel computer can be significantly limited by the existence of a small fraction of inherently sequential code which cannot be paralyzed. Copes Law: There is a general tendency towards size increase in evolution. (Edward Drinker Cope) Ellison’s Law: The user base for strong cryptography declines by half with every additional keystroke or mouseclick required to make it work. (Carl Ellison) Brooks Law:  Adding manpower to a late software project makes it later. (Frederick Brooks Jr)     Isaac Asimo v's Three Laws of  Robotics : - A robot may not injure humanity, or through inaction, allow humanity to come to harm. - A robot must obey orders given to it by a human being except where such orders would conflict with the first law. - A robot must protect it’s own existe...

Best TVs of 2017

  2017 has seen high dynamic range technology giving rise to the very finest TVs. The powerful app of the 65Z9D is that it merges up Sony’s exemplary color and clarity technologies with a new high-end backlight system that’s apparently been tailor made to deliver maximum  HDR  impact while minimizing  LCD  TV’s typical light clouding/inconsistency problems. How does it do this? First, it puts more than 600 LEDs directly behind its screen rather than around its edges. Second, it provides enough electrical and processing control to enable every single one of these LEDs to produce its own light level independent of its neighbors. Lastly, new ‘calibrated beam’ technology focuses the  LED s more narrowly on the brightest parts of the picture, to give them more punch and expand the sense of contrast. The Sony XBR-65Z9D rewrites the picture quality rule book. Promising as all this sounds, though, the 65Z9D (known as the KD-65ZD9 in Europe) doesn’t make the b...

How To Make Your Laptop Battery Last Longer

Unplug any unused peripherals Its recommended you unplug any peripherals — say an external hard drive or webcam — while using battery power. In addition to transferring data between your device and your laptop, that cable is also drawing power to the peripheral itself even when you’re not using it. That’s an obvious drain on your laptop battery.

If at all possible, never drain your laptop battery below a 20% charge. This extends the life of your battery as usage with a low charge puts a strain on the battery itself, and eventually reduces its charging capacity. Keep your laptop out of hot and cold Use your laptop in situations where the ambient temperature is neither hot nor cold, DigitalTrends recommends. Extreme temperatures cause your computer to work harder, which in turn drain...
