March 18, 1931, Colonel Jacob Schick obtained a patent for the world’s first electric shaver. The inventor has invented an innovative tool for shaving is not out of the blue, and after “suffering” contractual military service in Alaska.
Colonel Jacob Schick
Problems with daily shaving in the cold a lot plagued Junior Lieutenant, which he first came up with the usual today razor with replaceable blades, but did not stop. The main purpose of Jacob was the creation of a razor for which it was not necessary to moisten with ice water (and then another in Alaska almost didn’t hang out) and soap the skin. The first sketches of the ingenious signalman did back in 1923, but the design was far from perfect, so 8 years later Schick made razor is much more compact and almost immediately established a mass production.
The world’s first electric shaver, still two-handed
Use first electric shaver was not very handy — one hand had to hold the engine, the second trimmer. But in the U.S. (and the world too), the razor became a sensation and was wildly successful even at the enormous price of about $25.
The following innovators in matters of shaving steel, the Dutch company Philips in 1939 was born the first rotary electric razor with two heads. And now the famous Gillette disposable machines will only appear 20 years later. By the way, several decades later, Philips will buy the Schick company and become one of the largest manufacturers of electric shavers in the world.
On 18 March 1965, cosmonauts first went into space. For such a task in the USSR built the ship “Voskhod-2” with the special airlock and had him start from the cosmodrome “Baikonur”. The crew consisted of commander Pavel Belyayev and pilot Alexei Leonov.

To pass the test space vacuum happened Leonov — he emerged from the airlock and 12 minutes remained in a vacuum. No men or equipment were not fully ready for such experiments, so unusual for the organism environment, the astronaut had to contend with fast breathing, excessive sweating and a soaring body temperature is on the verge of a fever.

In addition, Leonov’s spacesuit had inflated substantially and the pilot had to put a lot of effort to get back aboard through the narrow gateway of the ship. Another nuisance has been the distortion of the hatch and the lack of air on the ship (the leak was difficult to eliminate), and then the “Voskhod-2” was refused landing system. The problem was that the ship itself was very close and manual control is not assumed — chair astronauts were deployed to the side of the control panel. So the crew had to constantly move between the seats when boarding, we had to wear seat) and the dashboard of the vehicle.
With a failed control and without communication with Earth, the astronauts landed far from where it was originally planned — landing has passed in Perm region and a couple of days Belyayev and Leonov spent in the forest, and without regard of food.
The first person in space, of course, entered the history of Astronautics, and American astronauts were able to repeat the experience of the Soviet colleagues in June 1965.
On 18 March 1999, American hacker Kevin Mitnick has agreed to cooperate with investigators and pleaded guilty on 23 counts. Famous cracker was the first in the world a man who received a prison sentence for unauthorised access to a remote computer for criminal purposes.
Mitnick — the hacker with almost a Hollywood biography. A child from a dysfunctional family, in grade school, he learned to forge travel on the buses, at the age of 12 learned how to “cheat” ATS and learned free long-distance and local telephone service. At 16, Mitnick hacked into the school network, and not for the sake of ratings edits, but just out of interest.

Later Kevin went on to study at Computer Center of Los Angeles, and at this time, with friends enthusiastically hacked computer and telephone networks. One of my friends (or rather friend) was not reliable and passed Mitnick “guts” of the FBI, then 17-year-old hacker, received a suspended sentence.
In short, the illegal Hobbies of our hero, this measure had no effect, so in 1982 restless burglar gained access to the network of the Pentagon and air defense of the state of Colorado. A little later, Mitnick hacked into the servers of the University of South Carolina and through them “poked” network computer company Digital Equipment. Kevin dragged out of computers to new version operating system, was going to introduce it in “Trojans”, which is reported to be about the adventures of a user and to upload the file back to the internal network of the company. However, at some point his friend “reported where” and the hacker got busted again.
For downloading the operating system the attacker spent a year in prison, including 8 months in solitary confinement. But after he was released, all of the material about his criminal record disappeared from the computers of law enforcement agencies and from the Bank account of the judge who tried the case, “leaked” all the money.
As Mitnick gained experience, it was smoother, even on computers “anti-hackers” in 1994, he hacked into the computer of Tsutomu Shimomura, a Japanese American computer security specialist. Not immediately, Shimomura became suspicious, but on his computer was the system of protection, through which he began the hunt for our hero. After Shimomura connected to the work of the FBI, Mitnick was arrested on 15 February 1995.

Mitnick “got involved” is so strong that he sat in jail for four years — different laws for killing a man is punished less severely. Just on the hacker-“the recidivist” has always been new charges to extend his stay behind bars.
Since 2000, Mitnick was released and fully “legalized” — one of the most dangerous computer attacker, he turned into a fighter against hackers and information security consultant, wrote a lot of books and generally plenty bathed in the glory.
