Google Honeycomb tablet

Mesmo antes que os engenheiros de software da Google Android adaptado para rodar em comprimidos, Samsung e outros fabricantes descobriram maneiras de calçadeira a versão do telefone do Android para funcionar em aparelhos maiores. Os resultados foram mistos. Mas alguns produtos, como o Samsung Galaxy Guia, fez um bom trabalho levando a experiência do telefone Android para uma plataforma maior.
Em fevereiro, o Google tomou os envoltórios fora do favo de mel, uma versão do Android optimizado para comprimidos.

Enquanto a Apple praticamente clonados sua interface de usuário do iPhone para o IPAD, favo de mel do Google é mais uma adaptação. Usuários de telefones Android vai descobrir em breve, mas há mudanças significativas, como a falta de até mesmo um único botão dedicado para navegar de volta à tela inicial. Em vez disso, existem teclas que aparecem na parte inferior da tela, independentemente de como você está segurando a tela. Há também uma chave de volta e que mostra os aplicativos mais usados ​​recentemente. Há um físico interruptor on / off, controle de volume e trava para desligar a rotação automática do ecrã entre modo retrato e paisagem.

No final do dia, a maior diferença entre um comprimido de favo de mel eo iPhone é o trade-off entre flexibilidade e simplicidade. A Apple criou um sistema que é muito fácil de usar quanto tempo você pretende utilizá-lo exatamente do jeito que a Apple pretendia que fosse utilizado. Google oferece flexibilidade, poder e capacidade de expansão.

Apple problemas em Pequim

A longa espera para produtos Apple em Pequim ficou feia no fim de semana, quando irrompeu um conflito fora de uma das lojas da empresa, resultando em uma porta de vidro quebrada e ferimentos aos clientes e um funcionário. Apple iPad dois tinham ido à venda, mas foi o iPhone branco 4, lançado uma semana antes, que causou o problema.

Nas últimas duas semanas, longas filas se formaram fora da loja da Apple de Pequim para o lançamento local do iPhone branco da empresa 4, e depois do IPAD 2, que foi colocado à venda no país na sexta-feira. Procura dos produtos tem sido tão grande que as vendas dos dispositivos também atraíram cambistas, que desencadeou briga de sábado, de acordo com uma fonte familiarizada com o incidente.

Funcionários da Apple, então, decidiu bloquear e fechar a porta da loja. Um grupo de pessoas responderam agitando e agarrando a porta. A porta então se despedaçou, que feriu um funcionário da Apple, disse a fonte.

Após o incidente, tudo volta ao normal na loja. O longa também tinha ido, com apenas cerca de uma dúzia de pessoas esperando para comprar uma 2 iPad da loja. Avisos colocados no exterior, no entanto, alertam que a empresa entrará em contato com as autoridades se encontram cambistas vendendo ou assediar os clientes.

Apple tem quatro lojas na China: dois em Pequim e duas em Xangai. A Apple também utiliza revendedores autorizados e sua loja online para vender os seus produtos na China. Mas na segunda-feira, a loja da Apple para a China apareceu a nenhuma ordem de mais oferta de suas IPAD 2 ou o iPhone branco 4.

AZERTY

AZERTY keyboard layout is used in French-speaking countries.

In addition to the other systems are used, such as:

QWERTY - the world's most widely used
QWERTZ - used in German speaking countries

Differences with QWERTY:
Keys A and Q are swapped
Keys Z and W are swapped
M is moved from the right side of the Sun on the right side of L (in place of the semicolon).
In addition, on both AZERTY keyboards, such as French and Belgian, 0-9 keys are in, albeit in the same places, but you must press the "Shift" to have access to them. A similar arrangement of figures can also be found on other keyboards (eg the Czech and Slovak).

Dvorak keyboard

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

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.

The develpment of keyboards

82-key - keyboard and XT PC
84-key - Type AT Keyboard
101-key - extended keyboard with numeric keys
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.

The keyboard is able to remember more than 230 different combinations.
The first computer with a keyboard was created in 1960.

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.

The cons of quantum calculations

The idea of a quantum computer also has its weaknesses. The most serious of them is called decoherence. It consists in the fact that quantum states that are superpozycjami stationary states are extremely unstable. Under the influence of external factors the system "falls" from the state of superposition and "jumps" to one of the stationary states. This is done within a small fraction of a second. Even the slightest contact with the environment can affect the result. One tested ways to solve this problem is keeping the atoms in magnetic traps and control them with pulses of laser light.

The pros of quantum calculations

Quantum computer, although it draws on other physical properties than classical computers do not make it possible to solve a new class of problems. Any problem not insoluble by a quantum computer can be solved by a classical computer. However, due to the specific properties of quantum computers could be some problems solved much faster, which in practice significantly poszerzyłoby range of problems for which computers can be used. A classic example is Shor's factoring algorithm, used to break down numbers into prime factors. Implementation of a similar algorithm for kilkudziesięciocyfrowych numbers in modern computers would exceed the average length of human life, and for even larger numbers - the life of the universe. On quantum computers would be possible to carry out these operations in a more realistic period.
The most common model of quantum computation the quantum state of the system is represented by a vector in Hilbert space skończeniewymiarowej (qubit). However, the operations carried out are described by unitary matrices.

Quantum register

Quantum register is a group of atoms, each of which implements one of the qubits. Each string of zeros and ones of length equal to the size of the register can be written in kubitach this system (as in the register of conventional memory cells, but in the registry that at any given time can be saved only a string of zero-one). Quantum register, as consisting of qubits can be in a position which is a superposition of any number of zero-ones-strings. If in such a quantum register has been written by some large data base, the execution of certain operations on that register kubitach would be tantamount to perform this operation on all data at once.
If the registry contains a quantum superposition of very many of the results obtained in parallel, is to shell it, we need the data, we need quantum algorithms. Algorithms performed by a quantum computer algorithms are probabilistic. This means that running the same program on your computer, double-quantum, would have been obtained completely different results because of the randomness of quantum measurement process.

Quantum computers - how do they work?

The data in quantum computers are represented by the current state of quantum system which is the computer. Its development corresponds to the process obliczeniowemu. Appropriate planning of the evolution of quantum system, namely to create an algorithm allows a quantum theory, to achieve results in a much more efficient way than by using traditional computers. The basic elements of building a quantum computer are quantum logic gates. Quantum bit, called. qubit, according to the laws of the microworld will not have a fixed value of 1 or 0, as bit in a standard computer. In the course of the calculation will be located at some intermediate state. Governs the law of probability, like the position of an electron in an atom. Qubit is a quantum superposition of zero and one. A single quantum computer calculation result will be uncertain. , It is important to make a series of calculations and only their average value with high accuracy will determine the correct result - the more accurate the more, the computer calculations. Qubit carries the same time a lot more information than the zero-one bit. Therefore, it is able to perform multiple calculations simultaneously.

Physicists have long been candidates for qubits - the elementary particles, such as a photon or electron. The breakthrough came at the end of 1995. At the same time in several centers managed to construct a quantum gate, which further process qubits. Group of prof. Jeff H. Kimble'a of the California Institute of Technology in Pasadena used a cesium atom in an optical trap caught between the mirrors (the role played qubits photons of different polarities). The group of Chris Monroe of the National Institute of Standards and Technology in Boulder, Colorado has used beryllium atom illuminated by laser light. Yet another quantum gate, using the atom rydbergowski, created a team of Serge Haroche'a from the French Ecole Normale Superieure. To date, made a few simple computers, the calculations confirm the theory. We have already created the software for these machines. February 13, 2007 the company D-Wave Systems unveiled a system, called the world's first quantum computer register. But it is uncertain whether it can be called so: merely presented his action, despite construction

Quantum computers - where did they come from?

The possibility of building computers using the laws of quantum physics was noted in the early 80s by Paul Benioff of Argonne National Laboratory in the United States. Complete theory of quantum computer made in the mid 80s David Deutsch of Oxford University, UK. Join him then Polish computer scientist and physicist Artur Ekert, also linked permanently from Oxford. The idea attracted wider attention in 1994 when Peter Shor of AT & T Bell Labs in Murray Hill, came up with an algorithm that uses a quantum computer could quickly break down the very large number of products of primes.

Intel Ivy Bridge, cerca de 20 por cento mais rápido do que a Sandy Bridge

Basta ir até a primeira semana de lançamento do novo processador Intel Core série 'i' usando o núcleo, de codinome Sandy Bridge, uma gigante da Califórnia incentivou seus seguidores a Ivy Bridge. De acordo com informações preliminares, o novo sistema está a ser 20% mais rápido. A primeira CPU wykorzystującee Ivy Bridge devem permanecer LGA 1155, é definitivamente uma boa notícia para os detentores dessa plataforma, uma vez que já não mantém a vitalidade. LGA 1156 com os chips Nehalem foi expulso depois de apenas uma geração de processadores de Sandy Bridge, que também ofereceu um crescimento da produtividade inferior. Ivy Bridge será em versões com dois e quatro núcleos (modelos também suportam hyperthreading), e provavelmente apoiará PCI Express 3.0. Quando se trata de desempenho gráfico, podemos esperar que 30% da aceleração em relação à ponte de Sandy, uma das razões é o aumento do número de unidades da UE 12-16 (homólogos da UE, este shader Intelowe), e não como inicialmente se supunha a 24 Além disso, o sub-sistema tem um processador gráfico compatível com DirectX 11, OpenCL1.1, HDMI 1.4 e DisplayPort 1.1. Novos chipsets da Intel que suportam série 7 Ivy Bridge, codinome Panther ponto, eles têm de lidar com tais USB 3.0 e SATA 6 Gbps. Os acordos são igualmente compatível com Sandy Bridge, mas infelizmente o 6 chipsets série, codinome "Cougar Point provavelmente não será compatível com a Ponte Ivy.
Todos os que esperam que a nova plataforma com tecnologia de processo 22nm pode ser esperado para estrear no início de 2012.

Graças ao suporte da Microsoft para H.264 retornará para o Chrome

O Google anunciou recentemente que a proliferação de H.264 pode ser muito impacto negativo sobre startups. Todos os requisitos de licenciamento, de acordo com o H.264 será livre somente para os materiais contidos gratuitamente na rede. Os fornecedores de navegadores, sistemas operacionais e conteúdos pagos seriam obrigados a pagar pela tecnologia utilizada. Google como um dos maiores provedores de vídeo na rede, em vez disso webme seu formato, o que, no futuro, permitir a reprodução de vídeo contínua em diferentes browsers e dispositivos. Embora os argumentos são wyszukiwarkowego gigantes muito claras, e assim a Microsoft decidiu que o suporte para H.264 no Chrome precisa ocorrer. É claro que não tem qualquer influência sobre quais recursos serão no navegador, mas de acordo com as regras anteriores, a Microsoft tem uma extensão que vai reproduzir os filmes nesse formato. A reprodução não será, contudo, já foi feito com o uso das tags HTML5.

Android 3.0 irá criptografar todos os dados

Até agora, todos os PC Tablet rodando o Android poderia ser alimentado CPU, super extra telas e câmera wielomegapikselowe, mas não uma função, para desacreditá-los entre os usuários corporativos. Falando sobre a criptografia de dados. Isso vai mudar, porque o sistema operacional Android 3,0 Honeycomb introduziu esse recurso em seus limites - os usuários serão capazes de criptografar todos os dados armazenados sobre a mesa, os proteger com uma senha. Este recurso foi localizado no tablet Motorola XOOM, mas de acordo com o Google, estará disponível na maioria dos PCs tablet com o novo SO-I. Na descrição da função, podemos ler que você pode criptografar configurações da sua conta, os aplicativos baixados e armazenados pelos dados, arquivos multimídia e outros arquivos.
