1.Bob Ebeling Bob Ebeling, one of the main engineers behind NASA's Challenger rocket, which exploded in 1986, revealed that after NASA would not heed his warnings against launching in the cold weather, he told his wife the night before the launch, "It's going to blow up. 2.  NASA has 2 satellites chasing each other around the Earth tracking the distance between themselves to measure gravitational anomalies. Their nicknames are Tom and Jerry. 3.  Not only did a private US company pay for the research for the inexpensive "space pen" NASA uses, but the pen worked so well that the Soviets bought it, too. 4.  The Minnesota Vikings' new stadium cost more than a NASA mission to Pluto. 5.  A NASA astronaut (Don L. Lind) waited 19 years to fly in space. He was selected in 1966 but was chosen for canceled missions, or as a backup for missions. He said, "I was backing up two of the most depressingly healthy people you can imagine." He finally f

Lenovo Z6 Pro with Snapdragon 855 launching in April

Image
Lenovo Z6 Pro is arriving this month and will run on Snapdragon 855. Both were circulating as rumors and today the company VP confirmed them in a Weibo post. The phone’s predecessor, the  Z5 Pro  was powered by the Snapdragon 710, and fans had to wait for the  GT Edition  to see a flagship Qualcomm chipset in a Lenovo smartphone. The slider arrived with dual cameras, but it looks like the new device will have only one main shooter. There's a chance that the one camera for illustration purposes, with another one or two additional snappers to be positioned below (just like the Honor View 20 setup).         Lenovo Z6 Pro retail box We know the phone will have fancy HyperVision camera, Super Night View, Super Steady Shot, and some sort of 100 MP images. Other rumors suggest a 5G modem and a UD fingerprint scanner. | The Lenovo Z6 Pro will be sold in a neat  black and red retail box , designed by the team behind the torch for the Olympic games in Beijing back in 2008.

Mistakes people make when they start learning programming

Image
Not knowing the full expressive power of your language : e.g., C++ is used very commonly, but a very limited people know that it has  STL function libraries  as well. It can give you predefined functions with best possible complexities, e.g., algorithm, vector, string, etc. Not figuring out why you want to learn coding. Not doing ‘dry-run’  of code neither using a  debugger. Endless research, watching videos, etc. are worthless if you do not  spend time in real code-writing. Writing entire code in one block, i.e.,  not making functions  in code. Leap directly to make big softwares . Writing code without a plan : First, develop a solution for solving your problem, make some rough outline or algorithm and then start writing code. Planning Too Much Before Writing Code is also bad. Not setting practical specific goals and  deadlines  for learning coding. Not learning the  basic terminology related to that language and technology  that you are going to use. Example , wha

World's first single-atom quantum computer moves closer to reality

An Australian team of scientists has managed to make two atom qubits "talk" to each other, which, according to them, is a "major milestone" in the race to create world's first single-atom quantum computer. As part of a study, published in the journal Nature Communications, the scientists led by University of New South Wales (UNSW) professor Michelle Simmons managed to create qubits from precisely positioned individual phosphorus atoms in a silicon chip. Once positioned, the scientists could make two of those atom qubits communicate and correlate with each other. The team of scientists led by Simmons is said to be the only group in the world to witness the exact position of their qubits in the solid state. Prior to the latest advance, the scientists recently achieved two other breakthroughs using the same approach to building a quantum c

Top 5 Amaze Tech gadgets at Mobile World Congress (MWC)

  At the recently concluded Mobile World Congress (MWC) in Barcelona, various companies brought out new devices and technologies. Last year saw the Debut of ball-shaped robotic cameras, loT toothbrushes and Braille smartwatches. Blaze Tech education takes a look at this year's entries... Smart Bike Lock Dubbed as the world's first fully automated smart bicycle lock, Bisecu automatically locks your bike as you walk away from it and unlocks as you approach it. A truly automatic device, free from keys, Bisecu is designed for the next generation Riders. it is said to be both waterproof and weather resistant, and the battery should last for six months (though it’s rechargeable with the included USB). In case of theft, a 100db loud alarm with mobile push notification informs the owner that the bike is being tampered. The Bluetooth technology eliminates the need for both keys and a lock, The lock also serves as a cycling computer of sorts, providing riders
