Nekada davno su bili veličanstvena gvozdena čudovišta, a sad su skalamerija koja skuplja prašinu i pjesak…
Ups, možda ste pomislili na uništene tenkove i druga „korisne“ hrpe hladnog rata i Černobila ;)
Mislio sam na naše kompjuterčiće… hehehe…

Nikola Tesla

11. Tesla was born on July 10, 1856, in the Austrian Empire, now Croatia. He was the fourth of five children. After a checkered academic career in Europe, he worked as a telegraph drafter and electrician before moving to the United States to work for Thomas Edison in 1884.

10. If you couldn’t imagine life without your TV remote, thank Nikola Tesla for making it possible. Tesla invented, predicted or contributed to development of hundreds of technologies that play big parts in our daily lives — like the remote control, neon and fluorescent lights, wireless transmission, computers, smartphones, laser beams, x-rays, robotics and, of course, alternating current, the basis of our present-day electrical system.

9. Innovation runs in Tesla’s blood. Tesla once wrote: “My mother was an inventor of the first order and would, I believe, have achieved great things had she not been so remote from modern life and its multi fold opportunities. She invented and constructed all kinds of tools and devices and wove the finest designs from thread which was spun by her.” He credited both his parents’ influence for his success.

8. Tesla lived in New York City for 60 years, and remnants of his time there still remain. The corner of 40th Street and 6th Avenue in downtown Manhattan has been designated “Nikola Tesla Corner” — with its own street sign — because of its proximity to Tesla’s laboratory at 8 West 40th Street, where he worked in 1900 while building his now-infamous Tesla Tower on Long Island. At nearby Bryant Park Place, a plaque commemorates the Engineer’s Club, which awarded Tesla the Edison Medal on May 18, 1917. During his later years, Tesla fed pigeons in nearby Bryant Park.

7. Tesla received his U.S. citizenship in 1891, the same year he invented the Tesla coil. Tesla coils are a type of electrical circuit used to generate low-current, high-voltage electricity. Today, they’re widely used in radios, televisions and other electronics, and can be used for wireless transmission. A coil at Tesla’s experimental station in Colorado Springs, Colorado, created 30-foot sparks that could be seen from 10 miles away.

6. During the war of the currents, alternating current (AC) — favored by Tesla — battled for wide acceptance with direct current (DC), favored by Edison. At stake was the basis for the entire nation’s electrical system. Edison launched a campaign against AC, claiming it was dangerous and could kill people; Tesla countered by publicly subjecting himself to 250,000-volt shocks to demonstrate AC’s safety. Ultimately, alternating current won the fight.

5. Tesla designed the first hydroelectric power plant in Niagara Falls, New York, harnessing the power of the waterfalls he had marveled at since childhood. Construction took three years and power first flowed to homes in nearby Buffalo on Nov. 16, 1896. A statue of Tesla on Goat Island overlooks the falls today.

4. “Teslas,” a unit used to measure the strength of magnetic fields, are named after Tesla. Another namesake is Tesla Motors, the electric car start-up, in homage to Tesla’s role in the invention of the electric motor.

3. In 1901, Tesla received financial backing from J. Pierpont Morgan to build his Wardenclyffe laboratory in Shoreham, Long Island. The facility included the “Tesla Tower,” a 185-foot high structure with a 65-foot copper dome transmitter on the top. Tesla’s vision was to use the tower to transmit signals and free, unlimited wireless electricity all over the world. Thanks to Tesla’s early work, wireless transfer of energy is finally being realized today — from wireless chargers for electric toothbrushes and smartphones, to wireless electric vehicle charging, a technology being researched at the Energy Department’s National Labs.

2. Tesla was not a savvy businessman and suffered financially, despite his achievements. He lost financial backing from Morgan, who felt he couldn’t profit from Tesla’s wireless electricity concept, and sold his assets to make up for dual foreclosures on Wardenclyffe. The property was later sold to a film processing company. In 1917, the U.S. government demolished Tesla’s partially completed tower because it worried German spies would use it to intercept communications during World War I.

1. His long-abandoned Long Island laboratory will soon become a museum. Earlier this year, a non-profit organization raised enough money to purchase the long-abandoned Wardenclyffe. The group plans to restore the building and turn it into a Tesla museum and science education center.

Apple vs. Samsung

Too much ado about nothing.

Ladies and gents, we all forget what’s the most important thing here. Gadgets, the way they are used and the public that use them, are really not that much about spring at top/bottom of the list, or icons this or that way (square, rounded, or silhouetted). At the end of the day, we use them for two main reasons: because they have applications we need, and because they let us consume the content we want. Who have enveloped all that and offered the users one comprehensive do-all system – Apple and later Amazon. Only lately Google has joined the game.

The applications are the real force of the new generations of gadgets. And applications are available in hundreds of thousands on both major respective platforms. The real question for me is not how much were inventive the designers and engineers at Apple, Samsung or other companies, and by that award them patent rights for this or that. The question that should of been asked is what eco-system provides more creator-friendly conditions for various independent programmers, designers and concept creators. It is them who provide „meat“ to gadgets. Because of that we have enormous communities like XDA, and never ending list of fun sites for both platforms. After all, we all like to tweak our products, and many do the famous ROM „swapping“. Others jailbreak their products to activate options and capabilities locked by the manufacturer. Other write petitions to unlock the boot loader.

What does that mean? No platform is God given, and is not a best solution in this or that case.

Does that give them the right to be restrictive on their users and play them the way they want? Unfortunately yes, as long as we chose to give them our money.

If all of this is happening it is not the fault of Manufacturers. They just think they can go away with it. It is us consumers that have the last word.

Chose freedom. The way you did in the days of SOPA and other Mega-Minds „inventions“. For the rest, both Apple and Samsung are making money, what ever we say.

Cimni me, cimni, za … me štipni…

Već smo deseta godina u XXI vjeku, skoro vijek nakon što su poštovana gospoda Westinghouse, Edison i Tesla prošli sito i rešeto radi moderne budućnosti – u ovom slučaju struje.

Oni koji malo pažljivije prate dešavanja u svjetu nauke, vjerovatno su zapazili da se prilično zahuktala tehnologija bežičnog prenosa energije. Na sadašnjem nivou uspjevaju da napajaju mobilne telefone, laptopove – uglavnom manje potrošače i na jako malim daljinama. Iako smo još uvjek veoma daleko od Teslinih zamisli, to je nešto što već polako ulazi u komercijalnu upotrebu.

Da li je prošlo dovoljno vremena da ožive ideje stare gotovo 1 vijek. Sasvim sigurno, naučnici na tome vrlo vrijedno rade. Međutim, iako je neporeciv tehnološki napredak, nama će na ovim prostorima trebati još jako dugo da barem izdaleka pratimo sva ta čuda nauke. Read the rest of this entry »
