The Egyptians had large black obelisks to track the movement of the sun.

The Greeks had a water powered escapement mechanism, which transferred rotational energy into intermittent motions.

The Chinese had a mercury powered escapement mechanism, developed in the 10th century.

Today we have modern clocks, and we also have network time protocol.

The tracking of time grew in importance alongside the sophistication of society. Ancient societies needed time keepers to regulate growing aspects of their civilizations–including business, political, even social activities. These mechanisms grew more sophisticated throughout the centuries, until the advent of mechanical clocks using wheels and balance springs.

Today, much of the world operates under a standard 24-hour day, kept track with sophisti

Printed circuit boards are often used to create detailed and complex electronic devices. The path from the initial idea to a fully assembled PCB fabrication is a lengthy one that includes a lot of different planning and assembly aspects. If you are currently in the process of taking your design to the assembly process, you will want to consider the following price changing factors. These characteristics will change your PCB assembly quote.

The type of assembly that is completed
The type of assembly completed will significantly change the PCB assembly quote. Before PCB design was ever introduced, printed circuit boards were designed using clear Mylar sheets, up to four times bigger than the circuit board itself, on which designers would create a transparent photomask

It has been just over five months since Wannacry hit the headlines. The Ransomware attack, which targeted the UK?s National Health Service and also impacted companies like FedEx, may not have netted its creators much in the way of cold, hard cash, but it certainly demonstrated the potential of ransomware, infecting more than 400,000 machines everywhere from Spain to the United States and China.

Close to all (98%) of those infected were running Windows 7. Of course, Wannacry is not the only potential threat to business continuity. In fact, close to 60% of all businesses had reported some form of malware infiltration in the last six months, according an Osterman Research survey report. In this increasingly insecure context, more and more companie
