Macintosh OSX

The whole reason why macs never get viruses is because hackers don't see any profit in hacking a mac, even though macs arc is 64bit or higher currently pc's hold the market shares in the US, thus being hackers will see profit in hacking a pc and get more enjoyment out of it rather than trying to waste time on a mac, and wit a pc u can do a hell of a lot more than just a mac where u can only do graphic arts, music design, and so forth, and not even good enough to run games on it, oh yea another thing bout macs is that the os is pretty much locked and simplyfied where there's rly no probs with the mac osx and if there ever is any probs that the user experiences they always run to the apple store because they don't know squat on how to resolve the issue, when pc users can fix issues on their own and not have to run to the apple store for help. So yea I think the numerical order of os'es should remain the same currently.

THE STABLEST OS ITS PLUG AND PLAY ALL IS INSTALLED NO WORRIES ABOUT MALE WARE. 

Service is Apples best point. They cares much about the user experience. When they found some issues they slove them with updates. The most powerful os is OSX 10.8. Design and Dock are a plus point in the system it beats all. Its perfect for working and play sometimes a game. (Not playing hardcore games) but for what we have xboxes and PS3 consoles. It is the cheapest system on the marked and has the best update cycle. Best system on the market. All what you ned is onboard you don't need to install something. That's why Mac OSX is better than any other system.  IT can make all what a other system can do but you don't must worry about male ware viruses issues and you have someone to talk the geniuses hotlines and online chat on apples website.

SERVICE NO MALE WARE POWERFULNESS FEATURES YOU WOULD LOVE, NO DRIVER WORRIES, PERFECT PAKAGE FOR ONLY 15$.

By far one of the easiest operating systems to learn for a complete beginner (although switching from windows has a slight learning curve). Ideal for the artist and everyday user, the Mac OS is a personal favorite. The fact that it's unix based makes it quite similar to linux with very similar terminal commands. The only downside to Mac OS is the small range of games and the high price of the Macintosh computer required to run Mac OS X.

Mac is fully stability os in the world. The xp is not graphic os or any other os. I used all os except fedora, -security is most powerful, rich graphics. And main thing is almost all process works under commands.

They need to have more games but other than that... the compatibility with stuff like printers are excellent and it is very hardy and never crashes.

Macintosh are the best operating system of all the time! It's better than Windows. The graphic and the style it's very better! Macs run anything and they don't get viruses unlike windows and they don't slow down after years of use.

I love to be a Part of MAC. And What About YOU?

Fleeting Magnetism And OneWord: Plastics

Fleeting Magnetism

Eighteen months ago, China threatened to restrict exports of rare-earth metals, such as neodymium, used in the AC permanent-magnet motors powering the Nissan Leaf, Toyota Prius, and Chevrolet Volt. That prompted carmakers to explore alternatives. The most obvious candidate, already part of GM’s eAssist mild-hybrid system, is an AC induction motor containing no permanent magnets. (In an induction motor, static electric coils induce magnetism in a rotor made of steel laminations instead of permanent magnets.) While induction motors are slightly less efficient, they’re notably lighter, cheaper, and well suited to moderate-load, short-duration duty. The GM design shown here (ironically made in China), contributes more than 100 pound-feet of torque to curtail downshifts during passing and hill climbing.

OneWord: Plastics

 The trickledown from Formula 1 to road cars of ultralight, ultrastiff composites is migrating beyond carbon-fiber-reinforced tubs and body panels into suspension and powertrain domains. ZF’s experimental molded-plastic front and rear suspension systems cut both weight and parts count. Florida-based Composite Castings has produced a few four-cylinder engine blocks made of carbon-fiber-reinforced epoxy, saving 20 pounds over a comparable aluminum block. And an Australian firm, Carbon Revolution, has introduced the first single-piece carbon-fiber wheel that, in a 12.5-by-20-inch size, is 40 percent lighter than an aluminum wheel.

Golden Age of Gears And Goodbye to Flats

Golden Age of Gears

 Gearboxes have leapt from the greasy under(car)world into the limelight. Last year, Ferrari introduced an auxiliary two-speed automatic transaxle to power the FF sport wagon’s front wheels. Porsche presented a seven-speed manual for the new 911, and ZF unveiled a nine-speed automatic slated for use in 2013 Chrysler minivans. To keep the gear count rising, Hyundai has confirmed that the world’s first 10-speed automatic will arrive in the next-generation (probably 2015 model year) Equus and Genesis models.

Goodbye to Flats

 

Goodyear hopes its Air Maintenance Technology (AMT) will send flat tires the way of the buggy  whip. This elegantly simple idea positions a small air tube inside a groove molded into the tire sidewall. As the tire rotates, atmospheric air entering the tube through an inlet port is pressurized by sidewall deformation and pumped through a check valve into the main tire cavity.  AMT is self-regulating and requires no electrical power or electronic controls. The U.S. Department of  Energy and the Luxembourg government are backing Goodyear’s  AMT car and truck test programs.

Wireless Recharging And Thermal Juice

Wireless Recharging

Magnetic inductive-charging pads save the hassle of plugging in your cell phone, camera, MP3 player, or portable GPS unit. Scaled up, this approach could also recharge an electric car’s battery. Both Rolls-Royce and Audi have shown experimental systems in which energy is transferred inductively from a floor pad to a corresponding surface on the bottom of a car. According to Rolls, magnetic inductive recharging is 90-percent efficient and tolerant of alignment errors.

Thermal Juice

One-third of the energy in every gallon of the gas you burn is dumped out your exhaust pipe as waste heat. Schemes aimed at recouping some of that energy include turbocharging, turbo compounding (exhaust-driven turbines geared to the crankshaft), and the steam generators investigated by  both BMW and Honda. A promising approach also under development at BMW runs on the Seebeck effect that NASA used for decades to power spacecraft. Semiconductors heated by exhaust gas generate electricity during acceleration to supplement the re-gen energy recovered during braking. BMW believes that a thermoelectric generator (shown here) might improve mileage by  five percent.

Lighting-Bolt Iqnition And Cylinders on the Chopping Block

Lighting-Bolt Iqnition

Conventional spark plugs struggle to fire lean intake charges that are laced with heavy doses of exhaust gas. To prevent misfiring, Mercedes-Benz uses several sparks per combustion cycle in its new high-compression 3.5-liter  V-6. An alternative approach under development by Federal-Mogul is an Advanced Corona Ignition System, which sprays several ion streams into the combustion chamber like a miniature lightning storm. This high-frequency system occupies the same space as a conventional coil-and-plug ignition and has demonstrated a 10-percent mileage gain. Since this eliminates electrode arcing, which shortens the life of conventional plugs, ignition-system longevity should be improved.

Cylinders on the Chopping Block

 BMW and Mercedes-Benz reintroduced four-cylinder engines to their U.S. lineups after years of absence. Volvo is phasing out five- and six-cylinder engines in favor of threes and fours. Both Ford and GM have unveiled 1.0-liter three-cylinders slated for global duty. These and other makers are exploiting strides made with turbocharging and direct injection to deliver equivalent power from fewer cylinders and fewer cubic inches. The smaller, harder-working engines are cheaper, lighter, and significantly more fuel efficient. But don’t count on Corvette or Ferrari turbo V-6s—both brands have denied the existence of such engines for now.
