The Dvorak keyboard is a keyboard layout patented in 1936 by August Dvorak (professor at the University of Washington in Seattle) and William Dealey, as an alternative to the more popular QWERTY layout. It was called the simplified keyboard (Simplified Keyboard) or the American keyboard, a simplified (American Simplified Keyboard).

QWERTY - the symbolic name of the alphabet letters on the keypad of the basic typewriter and a computer taken from the first six letters in the number of digits in a row, from left.
The first typewriters were used alphabetic set of keys. However, with rapid typing of frequently used keys to the neighborhood resulted in a mutual arms stuck in the font. In 1878 r.opatentowano first typewriter with the QWERTY key layout.
Such a system font is more effective than alphabetical. Although untrained individuals is difficult to remember the arrangement of letters and does not give the optimal speed of writing, has become the standard keyboard layout in modern devices.
But this is not the system that guarantees the fastest possible pace of writing. There are other ways of distribution of keys (for example, Dvorak keyboard), whose layout has been optimized in terms of speed of character input, not to avoid jamming of fonts (which does not occur such as computer keyboards). In these keyboards, the most common signs are placed at each side by side, which reduces the path we have to overcome your fingers when writing.
For each language layouts are slightly different. This is due to additional, specific to a given language diacritics. In Poland, the keyboard layout that allows additional Polish characters is called a keyboard programmer (as opposed to the typist keyboard layout based on QWERTY). Polish diacritical marks (A, C, E, L, N, O, t, Z, Z) is obtained mostly by simultaneously pressing the "Alt" and letter-like character (such as é are obtained with a combination of Alt e) . The exception is the letter "Z", which is achieved by simultaneously pressing the Alt and x (as a combination of Alt and yields desired). In computers, Apple Macintosh letter Z and Z are swapped [1], ie Option + Z gave ¬, and Option + X Ż. Since Mac OS X 10.5 Leopard, the system is the same as in devices from other manufacturers.
The system programmer is used outside the Polish and the Czech Republic and Romania, the Romanian system programmer is more similar to Polish.
Czech diacritical marks (á, C, E, E, I, R, S, u, u, y, z) is obtained by simultaneously pressing the Alt key (or AltGr) and the corresponding keys such as 8, 4, 2, 0 , 9, 5, 3,,, [, 7, 6
Romanian diacritics (â, t, i, a, s) is obtained by simultaneously pressing the Alt key (or AltGr) and Latin letters, which derives an additional Romanian character.

104-key - keyboard extended to 101 additional keys for the Windows menu
Multimedia - keyboard extended to 104 additional keys.
Multimedia - keyboard extended to 145 additional keys, a new coding module and memory keys.

How to work from home effectively

- Find a separate place to work. If this is a bedroom or a room with a television, where they usually rest, more difficult to concentrate on work. These places we associate with relaxation, not with concentration and a willingness to solve problems.

- Create a separate profile on the system. During working hours, often distracting us the little things, like running or instant messaging in the browser history pages, suggesting that you can now read the jokes. A separate user account so you can arrange to have on hand only what you really need. In addition to logout and will signal to your subconscious that now end up having fun and we get to work.

- Establish specific working hours. If we give ourselves time around the clock, it usually ends up that in fact we are working around the clock. The finding that professional issues are "big time" for example, between 10.00 am and 16.00 pm, can reduce significantly the time spent at work.

- Inform the household that you are working. Mostly it is just that, "since, and so sit in your house, you can do ..." Tell that at pre-set hours "you can not do it" because you are working. If you were to exercise its functions away from home, you would not have access - there must also be a bit stop you from scattering during operation.

- Cherish social contacts. One disadvantage of telecommuting is that we have no contact with living people, which is usually many companies. We talk through emails or instant messaging - but it lacks the usual direct communication. For the sake of good mental health, one must necessarily balance the friends outside the company, meetings, socializing or just leaving occasionally for coffee somewhere.

Dual-cor or not?

The differences the old iPad and the nw one are noticeable, but not gigantic. The second-generation dual-core introduces, inter alia, the Apple unit A5, which is to be twice as efficient in the calculation and nine times more efficient at rendering graphics system than Apple's A4, which is based on the first iPad. What can we gain from a better body? Even smoother playback of movies or games, and it's basically all. At least for now, until the developers will not use force lurking in the second iPad - and this can be a problem resulting from a desire to maintain the compatibility of all published applications. Let us not forget that, IPAD controls at the moment 90 percent of the market and soon it will not change.
