In March, we wrote about the growing threat of yellow fever in Brazil. At the time, the disease had killed just over a 100 people. Unfortunately, the disease has only spread since then with many more people infected and more killed.
In this clip, you will learn how to create a simple constant current source so that all of your appliances are always running on the same current. This clip will explain exactly what this means and why you need to use it as well as how to set it up. Using the LM317LZ 100ma adjustible voltage regulator and one resistor, you can make a constant current source. With the LM317 1.5 amp version, you can make one with higher currents.

Eddy Currents are little circles of electricity created when metals are moved by magnets or even when magnets are moved by metals. To understand this practically take a regular piece of cardboard and drop it in between a horse shoe magnet. It drops normally with out being effected by the magnet. This is because the cardboard does not conduct electricity. Therefore it does not cause any eddy currents. But instead if you use an aluminum piece in the same way, it falls very slowly, because alumi...

With those tools, you can send your current location or share trackable real-time coordinates. But iOS always has a few hidden tricks to make things easier than they seem, and that's precisely the case if all you need to do is share your current location.
Nineteen days ago, several hundred people could have been exposed by a traveler with measles in Nova Scotia, Canada. The next day, someone flying from Minnesota to Nebraska may have spread the measles to other passengers. A couple weeks ago, it's possible that a man and his six-month old child spread the measles in several Seattle-based locations. Authorities are trying to locate persons who may have been in contact with these people. None of the persons with measles were vaccinated. Why?

In this tutorial, we learn how to not answer the "How do you stay current?" question. When you are asked this question on an interview, it's important to know how to answer it without looking crazy. To answer this correctly, do not answer what you "want" to do, employers are not interested in this. Also, hinting that learning is a low priority is not impressive to your interviewer. You want to be more specific when stating the obvious, so they completely understand what you are trying to say....
