Los nuevos comerciales de Palm WebOS

Desde que Palm fue adquirida por HP, han empezado a enmendar el rumbo. Primero despidieron a la agencia de publicidad que creaba los comerciales que por lo demas no explicaban nada (aunque fue un poco antes).

Por eso la presencia de los 2 nuevos comerciales donde muestran sus excelentes equipos, parecen ser mucho mas interesantes; y por lo menos muestran algunas de las funcionalidades de Palm, una cosa que los usuarios echaban de menos.

Sacando el molesto windows messenger de windows xp

Una de las cosas mas molestas, si es que usas windows live, es eliminar windows messenger, debido a que este muchas veces se enciende sólo ; y no te das cuenta cuando inicias una sesión, cuando muchas veces ni siquiera quieres hacerlo. Pues para esto es el siguiente consejo, eliminar definitivamente windows messenger de tu ordenador.Para ello debes hacer lo siguiente:

1.- Vas a inicio

2.- Seleccionas ejecutar

3.- Escribes la siguiente linea de comando en la barra

Nuevo Tablet, con 2 pantallas, asemeja mas un libro Kno

El Kindle, el iPad, el Courier, el Moodbook, etc, etc, etc... el mundo de los tablets. Todos prometen soluciones, nuevas funcionalidades y mejores experiencias. Y todos son criticados. Que son muy pesados, que no se les puede conectar nada, que no son útiles para navegar en Internet o que no ofrecen una buena experiencia de aprendizaje porque en 10 o 12 pulgadas no se puede desplegar adecuadamente un libro de estudio.

Iron Chemical Compound

Iron is a chemical element with the symbol Fe (Latin: ferrum) and atomic number 26. It is a metal in the first transition series. Like other group 8 elements, it exists in a wide range of oxidation states. Iron and iron alloys (steels) are by far the most common metals and the most common ferromagnetic materials in everyday use. Fresh iron surfaces appear lustrous silvery-gray, but oxidize in air.

Iron is the most common element in the earth as a whole, and the fourth most common in the earth's crust. It is produced as a result of stellar fusion in high-mass stars, and it is the heaviest stable element produced by stellar fusion because the fusion of iron is the last nuclear fusion reaction that is exothermic. Iron is the most widely used metal, and iron compounds, which include ferrous and ferric compounds, have several uses as well.

Iron has been used since ancient times, though not as early as bronze or the other copper related alloys. Iron is ubiquitous in modern life; it is used primarily for its structural strength. Pure iron is soft (softer than aluminium), but the material is significantly strengthened by addition of minute amounts of impurities, such as carbon. Alloying iron with appropriate small amounts (up to a few per cent) of other metals and carbon produces steel, which can be 1,000 times harder than pure iron. Iron is smelted in a blast furnace, where ore is reduced by coke to metallic iron.

Elemental iron is reactive; it oxidizes in air to give iron oxides, also known as rust. The rusting of iron and iron alloys is undesirable, and has a major economic impact. Unlike many other metals which form passivating oxide layers, iron oxides occupy more volume than iron itself. Thus, iron oxides flake off and expose fresh surfaces for corrosion.

Iron exists from oxidation state −2 to + 6, although +2 and +3 are the most common. It forms binary compounds with the halogens and the chalcogens. Among its organometallic compounds, ferrocene is significant as the first sandwich compound discovered. Iron plays an important role in biology, forming complexes with dioxygen as hemoglobin and myoglobin; these two compounds are common oxygen transport proteins in vertebrates.
