How did 3d printing emerge?

3D printing is taking the world by storm. Even since their inception, 3d printers have continuously become more and more powerful. They started out printing small plastic blocks and have by now moved on to printing tools, decorations, prosthetics, even gun parts.

3D printer’s golden hands

We are on the threshold of an age where we will be able to print just about anything we want – from evening shoes to toys and tools, to firearms. How much is true in the announcement that 3D printers will bring us a new industrial revolution?

After the unexpectedly tumultuous development of computers, we are approaching the limit of digital technology development. There are no more new processors, each of which is at least three times faster than its predecessor. New video units are only moderately different from the previous generation, supercomputers and artificial intelligence have slowed significantly, and monitor makers are scattering the stereoscopic 3D technology found back in 1838.

For over a decade, the computer industry relied on repackaging old technology into new enclosures, so we had smaller laptops, palmtop, and tablets.

None of this was fundamentally new, so users were already tired of changing colors and masks on their “smartphones”.

And then a miracle happened, the Additive Manufacturing emerged, announcing a new paradigm in the digital age. The result of a computer no longer has to be just an imprint of one’s imagination in a virtual space, which will disappear with the …

Calories In A Cup Of Joe

Black, cream and sugar, these are the usual options for coffee a few years back. It has evolved thru the years since then. Now, you can get an espresso, flavored, blended, frozen and ice with a wide range of syrups, lighteners and sweeteners. With all these on a cup of your favorite joe, you are left wondering, how many calories is in my cup?

In all actuality, coffee on its own has almost no calories. Starbucks brewed coffee has only 5 calories for the Grande size (16oz) and contains 1 gram of protein. That should be a relief to know for those who drink plain brewed coffee. But hey, I like mine with sugar and cream. So that would be 1 ounce cream and 2 packets of sugar, amounting to about 60-80 calories more. But if you are into blended coffee, then you are in for a shock. Calorie meter goes up to about 500-700 for those types of coffee.

Below is some of the well-loved cup of coffee we ordered from our favorite coffee houses.

Brewed Coffee – Almost all of the studies showing benefits of coffee to a person, is done with regular brewed coffee. Add that information to the fact that it only have 2 calories for an 8oz cup.

Homemade Latte – Latte is a classic Italian Coffee drink that is 1 part espresso, 1 part milk and 1 part foam. It contains 91 calories for an 8oz cup.

Traditional Test Automation vs. Manual Testing

The most significant benefits of traditional test automation are the decreased test execution time and cost, and increased test coverage for each testing cycle. The downside of test automation is the increased test development cost as on quality assurance. In a typical test automation scheme, each test is first documented by a test engineer then scripted by an automation engineer. The cost benefit of automated testing comes through the repeated execution of the test automation suite. Since the cost of executing an automated test is far less than the cost of executing a manual test, eventually the decreased test execution cost will make up for the increased development costs.

For example, suppose that a test engineer costs your organization $60/hr, and an automation engineer costs your organization $100/hr. The test engineer can create 5 new test cases per hour during test plan development, and can execute 10 test cases per hour during test execution. The automation engineer can develop 2 test cases per hour. Once those test cases are completed, a test engineer can execute and analyze the results of 50 tests in one hour (typically the test engineer will run the tests overnight, or while he is doing some other work, then analyze the results once the test is done).

Suppose you create a test plan with 1000 test cases:

• For manual testing, your initial test development cost is: 1000 tests * 1 hour/5 test cases *
