8 key factors to overcome your opponent in Google

No one can claim to know the algorithm used by Google to sort search results, but it is relatively easy to investigate what factors are involved in it and to what extent affect the algorithm. In addition, the network will find much literature on the subject and you'll be extending knowledge if the topic you are passionate about.

This article presents 8 key factors that will help you know why other sites are above yours, and how you can overcome them.

1. Decide what words are going to concentrate your efforts

You can not fight for many words at a time, so concentrate your efforts in about 10 words or phrases that you think can be searched in Google for your target audience.

Begins the analysis that will lead to success making a list of the top 5 websites listed in the top results when looking for those 10 words.

Browse through the 5 pages that will appear. Make special attention to discover what words are targeting them.

2. Find out where are located the words for which you want to fight

Look carefully at where they are placing keywords.

Google gives more importance to words that are located in certain parts of a web page. The most important part is the URL (the address of your website), the following is the tag <title>, the following are the headers <h1>, <h2> and <h3>, then come the words that are links to other pages, and the importance is diminishing, although it is always higher than the plain text, if the words are bold, italicized, is part of a <alt> (alternative text on images), etc ...

3. Find out what keywords density have

Keep in mind a few things:

Google (y el resto de buscadores) funcionan por densidad, no por valores absolutos. Así que si en tu URL o en tu título tienes 50 caracteres y 9 coinciden con los que el usuario busca, el valor de tu URL o de tu título es de 9/50. Así que procura no poner textos superfluos o urls con tropecientos números que corresponden a una sesión de usuario o a algo parecido.

Also consider that from March 2004 Google works by characters, not words. Hence in the preceding paragraph has written "characters" rather than words. Until March 2004 if your title was "wooden tables Office" and the user was looking "wooden tables", the value of your degree was 3/5 (in Castilian not seeped prepositions and considered words). Now is not the case. Now going by letters. Thus, if someone searches a derivative of a word or a plural, or conjugated verb, the page containing something similar is also included in search results.

Cuando descubras dónde tienen situadas las palabras, mira con qué densidad aparecen. En tu página web, haz que tengan mayor densidad que en las suyas. Lo puedes hacer incluyendo la palabra más veces o incluyendo menos palabras que no tengan que ver con esa búsqueda. La cuestión es elevar la densidad y superar la suya en cada una de las partes donde aparezca la palabra.

Eye do not go overboard ... Google penalizes pages with suspiciously high densities. You can get a 100% density in the title and URL, without anything happening. But a page where you put a word repeated 100 times, everywhere, bold and links, and do not include any other text, you can be assured that it will be expelled from Google. So moderation.

Also, think that your website has to be read by your users / customers ... it is essential that the text is aimed at them, not search engine effectiveness.

4. Find out how many pages have their web pages

The more pages you have indexed in Google, the more likely they are to participate in the struggle for certain words. There are also indications that Google puts in a better position to web containing a large number of pages where the search term is included.

So, on the one hand, it includes the words why you want to position yourself in the maximum possible pages. On the other hand, try your web have about 200 pages or more.

But once again, find out what your competitors do and include it in the table started to do at the beginning of this study.

To find out how many pages are indexed in Google, simply type in the search engine box:

website: www.nombredelaweb.com

(Eye not include a space between site: and the URL)

To find out how many indexed pages contain a particular word or string of words, simply type in the search engine box:

website: www.nombredelaweb.com "palabra the phrase"

This will give you the number of pages containing the phrase "word or phrase" on the website www.nombredelaweb.com

5. Check the number of links pointing to your pages

The PageRank algorithm that forms the (cultural note: PageRank means "Larry Page rank", not "page ranking"), is formed by many other algorithms and is quite complicated to understand. But there are some basic features that can easily be applied to your website.

PageRank influence in all, the number of links pointing to a website, the density of these links on the source page and the PageRank of the source page.

So this number 5 will focus on the first of the factors affecting PageRank: the number of links.

Again, note the number of pages that link to each of the 5 competing websites that are analyzed on your list.

To find the number of links to a page, simply type in the search engine box:


Since March 2004, Google gives less value to the links come from pages with similar IP to yours, so do not need to cheat: Google knows.

We wrote an article about Hilltop algorithm used by Google to calculate and filter the PageRank of the sites, a few months ago: HillTop

6. Analyze what kind of web linking to your competitors.

In all likelihood you can not include in your listing the PageRank of each page that link to those of your competitors, but it is important to see what kind of website they are, what PageRank have, how many other websites link and what words they use for linking to your competitors.

The higher the PageRank of a page that links to you, the greater the number of points you get for this link. So look for pages with high PR and link you get.

To conclude this point, do not forget that Google and other search engines, everything works by density, so if a web out 100 links to other websites, the value of a bond to come to you is 1/100 . So forget about link farms. Get links to your web pages with few links and a high PageRank.

7. Find out what words your competitors use the links to go to their websites

If the search word is part of a third party link to your website, you have a bonus in points (to put it in some way). So if you dedicate yourself to making wooden tables Office, ensures that the pages that link to yours using the phrase "wooden tables" to link you, instead of www.minombredeempresa.com

Obviously, you can not always control what words to use third-party websites to link to yours ... but when you can do it, remember this clause 7: Remember the bonus to take you if you get !!

8. Write down what pages have PageRank your competitors

Do not forget to include a column in your study indicating which have PageRank websites of your competitors. This will help you understand why they are in the top positions.

Remember to increase your PageRank must, above all, increase the number of pages that link to yours. So if you have a PageRank of less than 4, put to work to get links. If you have more than 4, it is quite difficult if you do not perform any upload, well designed and with a good strategy specific campaign for this purpose.

See how it works Google Scholar, Google's new search

At the end of last week Google put online the beta version Google Scholar, Its new search engine to locate technical information among all articles, studies, theses, white papers, case studies, Technical reports, research, documentation research centers and universities, books, etc ... published.

It has not even been a month since Google launched its Google Desktop Search tool that has pleasantly surprised us again throwing Google Scholar.

The initial image is very similar to Web search engine Google, however, we have introduced a search topic and give the button "search"We ordered a results window with no commercial information without ads appear. Sorting criteria take into account the content of the documents, the author, the publication in which the document appears, in a similar way as it does for the Web version with links-inThe number of citations to that article in other documents. Finally, it draws attention to the links shown are not unique, as the same article may be published in different media. Even it has links to documents referenced by studies (even they can not exist on the Web), similar to the concept links-out Web version.

To limit searches by author, allows us to include in the filter box seeker "author:" we can write alone or with the theme or concept we are looking to limit the number of results to be obtained.

Turning to practice, I have dedicated myself to making a few searches in the two versions of Google to see the real differences. The first search I've done is "eye tracking technology". The Web version has given me references and four ads 1,040,000. The first 10 results, 4 are companies that sell such technology-related solutions. The remaining 6 are studies or related technical information. In contrast, the results shown by 13,600 Google Scholar 100% are technical, not commercial references or advertisements appearing ... so perfect!

I have taken a second example, "web metrics". The results have been curiously very similar. Of seven advertisements and 2,050,000 results for the Web version, 40% were technical results and 60% commercial results. For version Google ScholarThey have been 28,000 the results, all technical again.

Finally, mention the authors whose technical documents have not yet been indexed they should ask their school, college or publisher to contact Google Scholar to include such content. Google Scholar moment does not allow direct publication by the author of reports and documents. More information is available in the FAQ.

Definitely a tool that will be talking in the research community from now.

Invent a robot that hunts flies for energy and self-sufficient

Although it seems a joke, it is not. The New Scientist magazine has published in its Monday edition, this great invention. A robot that uses the sugar in the exoskeleton of the flies and allows (while flies from view) the robot does not need another power source.

If we read well the article we see that the thing is not as simple as it seems at first glance. Input power the robot obtained by breaking polysaccharide chains of the exoskeleton of the flies is very low and only allows the robot to move 2 centimeters every 12 minutes.

On the other hand, there is the problem of making the flies come ... but that have worked out well. The robot uses a flavor, synthesized from human feces, which attracts flies into a funnel that sucks up the digestive tract. Hahahaha ... you can not deny that is well thought out.

Robotic Anecdotes aside, the investigations that led to the invention of this robot open up endless possibilities:

  • The energy of the polysaccharides can be used to supplement the solar energy to manufacture any kind of "thing" that needs to be energetically autonomous. (How about a robot that when not shine, eat potatoes, beets, ... or GM soy?).
  • Production of electricity for households may attempt be made from the feces and organic waste, home users own: which would reduce the amount of waste that cities need to collect, process and eliminate. The most abundant polysaccharide in nature are starch and cellulose ... our wastes are filled with them. 50 gr. sugar can remain alight 40w bulb for 8 hours.
  • The use of sugar batteries to replace batteries in mobile phones and other devices that need to be recharged by plugging into the mains.
  • How about a water filter potabilice waste and generate electricity? Ideal for a spacecraft or orbital station. In general, ideal for any closed ecosystem.

First images of the models of the future space elevator

Tomar un ascensor hacia el espacio puede sonar a ciencia ficción, pero en Seattle se está construyendo el primer prototipo de ascensor espacial.

Lo cierto es que aunque la imagen que muchos tenemos en la cabeza, es parecida a un ascensor más o menos común, la realidad sobre la que trabajan los científicos es un poco diferente. Para empezar, no se trabaja con un cable sino con una cinta ancha, fabricada con nanotubos de carbono… más bien, algo parecido a un monorraíl o una cremallera.

…Y en esto es en lo que están trabajando en Seatlle.

La empresa LiftPort Group cuenta con una beca de 570.000 dólares de la NASA para construirlo además de fondos de inversores privados y de un plan de empresa que se basa en generar ingresos desde el primer año de investigaciones.

Cómo es un ascensor espacial

El concepto es simple. El ascensor es básicamente un cable, atado a un extremo a una plataforma, que puede estar en el mar flotando o en tierra.

En el otro extremo hay un satélite, en órbita de 35.000 Km flotando sobre la Tierra.

Las mercancías, tales como partes de una estación espacial, o humanos que viajan por placer, son catapultados por el cable y puestos en órbita, en una fracción del coste actual, ya que coordinando las subidas y las bajadas de material, la fuerza de la gravedad es quien hace la mayor parte del trabajo.

Cómo se está construyendo: un nuevo modelo empresarial

La empresa LiftPort está divida en varias pequeñas empresas, que cada una por su lado, atacan una faceta distinta del enorme trabajo de ingeniería que supone la construcción de un ascensor. Así, existe una empresa que se dedica a encontrar la mejor manera de construir la cinta de nanotubos y a investigar la esencia de la cinta, otra que trabaja en la propulsión de la caja del ascensor y en la caja misma… también cuentan con una empresa que se dedica a promocionar el ascensor y con otra que gestiona los fondos.

El trabajo de cada una de estas empresas llevará a la invención y comercialización de muchos otros artefactos que serán útiles para otras industrias. Por ejemplo, parece que a raíz de las investigaciones han dado con una nueva forma de proceder a la vigilancia aérea, y también a un nuevo tipo de antenas que flotan en globos y que permitirían grandes redes wireless.

Así que está claro que el modelo de negocio de LiftPort se basa en ir obteniendo financiación a partir de la comercialización de todo lo que se invente por el camino. Porque recordemos que LiftPort no es una empresa de científicos (aunque los haya…) sino una empresa de ingeniería… y un ingeniero, un científico y un comercial… forman un trío que en manos de un financiero genera buenas expectativas, cuanto menos.

Las imágenes de la primera maqueta

Las imágenes que ilustran este artículo son de un robot llamado “Squeak”, que es capaz de subir por una cinta de plástico. Parece que este robot, a otra escala, es bastante parecido al futuro ascensor espacial, y según ha declarado Michel Lane, Presidente de Lift Port Group, el equipo que trabaja en la propulsión de la caja del ascensor, lo hace a partir del Squeak.

Una de las novedades de este robot es que funciona propulsado por un rayo láser enviado desde la base en la Tierra y que choca contra una plataforma dispuesta en un lateral del robot, haciéndolo avanzar.

Las claves del ascensor espacial

…Pero volvamos al ascensor: los tres pilares técnicos para la fabricación del ascensor, y en lo que se trabaja en LiftPort son:

  1. Un transporte robótico que resista tanto la presión a nivel del mar, como el trabajar a más de 50.000 km de la Tierra. Las preguntas: ¿ruedas? ¿raíles? ¿cables?
  2. Hallar un material super-resistente que no colapse sobre su propio peso cuando tenga 100.000 km de longitud.
  3. Hallar una fuente de energía para el robot. ¿Energía Solar? ¿Baterías?

Si se construye un ascensor que resuelva estos tres pilares técnicos, también podrá fabricarse una variante del ascensor que dejaría fuera de combate las lanzaderas de la NASA… ya que con alguna modificación, el robot y la cinta podrían lanzar el material y propulsarlo hasta la órbita de Marte o de cualquier otro planeta. Una vez en esa órbita, otro ascensor espacial podría bajarlos hasta la superficie. Y viceversa… desde Marte se podrían enviar materiales a la Tierra (…esto ya empieza a sonar a Kim Stanley Robinson en “Marte Rojo” Ed. Minotauro).

Las universidades, volcadas también en el proyecto

Michael Lane ha estado dando conferencias y seminarios por diferentes universidades del área de Seattle, para conseguir que un gran número de estudiantes verse sus tesis de doctorado en tecnologías relacionadas con el ascensor.

Y como era de esperar… ya ha aparecido un magnate norteamericano que ha creado el “Elevator: 2010” que premiará innovaciones en el desarrollo de robots tipo Squeak, así como cintas de materiales súper resistentes y sistemas de propulsión que sean viables para el ascensor.

Lo cierto es que el ascensor es un proyecto muy atractivo que lleva la fama y el dinero asociados. Sin duda, la empresa que ponga en funcionamiento el primer ascensor espacial, tendrá una fuerte ventaja sobre sus posibles competidoras. Se espera que en los 20 próximos años, haya hasta 10 ascensores espaciales. Las malas noticias son: que no se espera que haya ningún ascensor terminado durante los 5 próximos años, más bien se espera que esté construido entre 8 y 10 años a partir de ahora…
… “La Paciencia es la madre de la Ciencia.”

La primera cita del “Elevator: 2010” será en junio 2005 y el premio, 50.000 dólares… así que si eres ingeniero y te gustan los cacharritos que pueden ayudar a crear al primer ascensor espacial…ya sabes…

SpaceShipOne, and Virgin Galactic MAV wins $ 10 million X-Price

Como indicaban todos los pronósticos, el x-Price fue para el SpaceShipOne, la nave creada por el equipo de Paul Allen (Microsoft) y Burt Rutan (pionero aeroespacial), con el auspicio de Richard Branson y su recién fundada empresa Virgin Galactic.

El 4 de octubre, Brian Binnie, a los mandos del SpaceShipOne, subió por segunda vez en menos de 5 días a 112 kilómetros de altura, estableciendo el récord en altitud jamás alcanzada por una nave privada.

El jurado del x-Price declaraba ganador, y ofrecía un premio de 10 millones de dólares, a la primera nave que consiguiese por 2 veces consecutivas, en menos de quince días, situarse a 100 Km. de altura, en una nave tripulada que pudiese llevar el peso de 3 personas y que fuese capaz de aterrizar de nuevo en el Aeropuerto de Mojave.

El SpaceShipOne es propiedad de la empresa Mojave Aerospace Ventures, de la cual Paul Allen, cofundador de Microsoft y el pionero espacial Burt Rutan, son socios fundadores. Ambos han sido también los diseñadores y creadores de esta nave espacial, que ha costado más de 20 millones de dólares.

Hace ya unos días, justo antes de que el SpaceShipOne hiciera su primer vuelo en el x-Price, Richard Branson anunciaba en rueda de prensa que Virign Galactic, una de sus más recientes creaciones empresariales, contaba con comercializar vuelos espaciales con el SpaceShipOne, a partir de 2007. “Esperamos convertir en “astronautas” 3.000 personas, en los próximos cinco años y hacer realidad su sueño de admirar la majestuosa belleza de nuestro planeta y las estrellas en todo su esplendor, así como disfrutar de la increíble sensación de la ingravidez“, explicó un eufórico Richard Branson en una rueda de prensa.

El precio del billete, que incluye un curso formativo de tres días de duración, alcanzará en un primer momento las 115.000 libras (unos 169.000 euros). La nave que espera contratar Vigin Galactic es un nuevo SpaceShipOne (que se llamará SpaceShipTwo :) ), que tendrá capacidad para 5 personas y un piloto, y que empezará a construirse a finales de este mismo año.

El turismo espacial parece que va en serio

Aparte del hecho que varios magnates se están ahora dedicando a construir naves espaciales (ya comentábamos en un artículo anterior, que hay rumores fundados que apunta a que Jeff Bezos [Amazon] ha fundado la Blue Origin, empresa que se dedicará al turismo espacial), sin duda, el éxito del SpaceShipOne abre la era del turismo espacial.

Y aunque el x-Price ya tenga ganador, obviamente, el resto de los equipos participantes (24 equipos), van a luchar para ser ellos quienes consigan convertirse en “el primer vuelo de turismo espacial”. Esta lucha es la que realmente llevará a dar comienzo a la nueva era. El equipo canadiense de Da Vinci Group, ya ha vaticinado que serán ellos quienes consigan este hito.

El sector privado toma la iniciativa

Si algo ha demostrado el x-Price es que el desarrollo aeroespacial ha pasado por el mismo punto de inflexión que pasó la aeronáutica después de la segunda guerra mundial: el sector privado toma las riendas de las investigaciones y los desarrollos y busca rentabilizarlos ofreciendo sus servicios al público en general.

Pero no todo es entusiasmo y buenas esperanzas… los primeros críticos ya han aparecido y hacen hincapié en la peligrosidad de estos vuelos y en el hecho de que “las empresas privadas, normalmente, están dispuestas a tomar riesgos que las empresas estatales no tomarían“… NASA dixit (desde los desastres del Challenger y del Columbia, va con pies de plomo en todas las misiones y cualquier nuevo error donde perezca un humano, implicará la reducción de su presupuesto y el cuestionamiento de todos sus proyectos).

Otro tema es la rentabilidad de estos vuelos… ¿Cuánta gente estará dispuesta a pagar los precios de los billetes que le llevarán a ver la Tierra desde el espacio?… Imagino que siempre habrá un “Denis Tito” (el personaje que pagó varios millones para viajar hasta la Estación Orbital Internacional, hace 3 años) dispuesto a pagar lo que sea para ver nuestra joya azul desde el espacio… pero de ahí a rentabilizar las inversiones a corto/medio plazo… ya veremos.

Un nuevo premio

De momento, y para animar a seguir con la carrera espacial privada, la Nacional Space Society ha anunciado un premio de 50 millones de dólares, ofrecido por el millonario Robert Biguelow, para la primera nave privada que consiga ponerse en órbita.

Veremos quién será el ganador…

Ansari X-Price: Concurso de sondas espaciales – Premio a quien consiga situar una nave a 100 Km

Mañana se celebra el Ansari X-Price en el desierto de Mojave, California. Este año el premio por conseguir situar una nave a 100 Km. de altura, es de 10 millones de dólares. El gran favorito es el equipo de Paul Allen (Microsoft) y Burt Rutan (pionero aeroespacial) con el SpaceShipOne.

SpaceShipOne de Virgin Galactic (que es una de las naves del equipo de Paul Allen y Burt Rutan), hace que cada vez estemos más cerca de los vuelos espaciales privados.

Pero volvamos al X-Price:

El X-Price consiste en conseguir 2 vuelos a 100 Km. del suelo, en un intervalo máximo de dos semanas.

Allen y Rutan están seguros de conseguirlo, pero hay 24 equipos más que competirán contra ellos.

Entre éstos, se encuentra el equipo formado por Eric Meier y Phil Storm, de la empresa Space Transport Corp Inc, ambos reputados científicos y con experiencia en la fabricación de sondas espaciales ya que ambos trabajaron para Aerojet Corp (Redmond [población vecina de Seattle]).

[Nota mental 1: Paul Allen = Seattle, Aero Jet Corp = Seattle… Parece que el área de Seattle está en plena ebullición aeroespacial. ¿Será por las varias generaciones de habitantes de la zona han trabajado en Boeing y en las empresas subsidiarias que se han creado a su alrededor?].

En el área de Seattle, también encontramos a otra empresa interesante: la Liftport Inc (Bremerton). Nada más y nada menos que dedicada a construir un ascensor espacial, que reducirá drásticamente el coste de situar material en órbita. Concretamente, según declaraciones de su Presidente y fundador Micheal Laine, el coste se reduciría de 20.000 dólares por libra de peso, a 400 dólares. El primer prototipo ya está en construcción.

(Artículo donde explicábamos hace unos meses, el funcionamiento de un ascensor espacial: space elevator)

A pesar de que parece claro que ganará el SpaceShipOne, la mayor parte de los participantes, lo que realmente esperan, es encontrar inversores para sus proyectos. Proyectos que van todos encaminados a situar gente y mercancías en el espacio, a bajo coste, cosa que de por sí, ya parecer ser un buen negocio.

Se comenta por medios no oficiales que Jeff Bezos, el fundador de Amazon.com también está trabajando en la creación de una empresa que fabricará naves espaciales. Concretamente ha fundado en Seattle (sí, otra vez Seattle) la Blue Origin, empresa que piensa dedicarse al turismo espacial.

[Nota mental 2: Con Paul Allen (Seattle), Jeff Bezos (Seattle) y Richard Branson (Londres) ya tenemos a 3 emprendedores multimillonarios, metidos en el mundo del turismo espacial. Esto es un indicativo claro de que hay oportunidades de negocio y dinero a ganar].

Desde éstas páginas haremos el seguimiento de la X-Race durante los próximos días…

Se aproximan años muy interesantes. Sin duda.

A9 discover how it works: the final version of the browser created by Amazon

Amazon A9How it works A9, what kind of algorithms is based, why it is called A9, who devised it, and all that we learned about this new search engine that will have to medírselas with Yahoo, Google and new MSN that Microsoft has in beta. Lets go see it!

Entry A9 in the search engine market opens an interesting period in the war for monopolizing the user searches takes a new dimension.

With the new version Amazon hung yesterday, we will review again the topics covered in the functional analysis to find the differences, see if they have corrected the weaknesses that showed in April and discover the innovations that presents this search.

Tracing Service Customization:

When you enter A9 and a member of AmazonThe same cookie recognizes and greets you with a "Hello Montserrat"That leaves me flabbergasted and, by the impact, I can not help but make me think of a"Welcome professor Falken, ¿Would you like a game of chess?” :-)

A part of the name, show me the seeker box and the history of all my searches A9 for if I want to consult some previous results (and I do not know if they have programmed, but could also serve to know your choices in the search results that have offered you, so we can offer them better next time you are looking for something ... we'll find out with time)

About the database used by A9:

Definitely A9 uses the database of Google, instead of using Alexa (remember that Alexa was bought by Amazon in 2000 and that Alexa has scanned more websites that Google ... but Google kept clean its database and deletes each 6 months, the web pages that their spiders have been unable during that period of time ... Alexa does not)

In April analysis, commented that using the Google database but not used whole, but only a portion of it. Now we confirm that uses whole: by searching the type site: www.solocine.com get the same number of results (approx.), Both search engines.

About sorting algorithm A9

It is to Google, without hesitation.

Offers some variation in the order of the results, but I think it is because both Google and A9 apply filters to the results without you know it, that the algorithm itself. For example, according to the language Google layout you have, when you search results in Castilian, it offers different results ... even if you insist that you want no filters through ...

It's a shame they have not chosen to use its own algorithm and compete with Google searches to see who offers the highest quality. If they use the same database ... A9 had it very easy to use Alexa ranking PageRank instead of determining the relevance of a page and thus influence the sorting algorithm results. But it seems clear that it has chosen to ally itself to Google rather than compete against him.

About advertising on A9

The system uses Google Adwords and Google's sponsored links. It served directly from Google's own machines (you can see in the url redirection ads)

What is the value proposition A9? What differs from the rest?

Since we are seeing at the moment A9 is basically a Google with another look&feelLet's see how it differs:

  • A9 offers image search results while providing web search and even while looking at the texts of the books Amazon. It is a convenient feature that facilitates this page to find out if you are interested or not.
    Most of the functions of the web work with "drag & drop". It is the new trend in the usability of applications for the end user. Everything is dragged and placed where you want it to work or to be saved.
  • Favorites Tracing Service (Bookmarks): If you drag bookmarks to the URL of a web of appearing in a result, it is automatically saved here so you can consult it any other day.
  • It offers 4 skins and 3 different font sizes: If you want to see A9 in purple and suitable letters without glasses myopic, A9 allows it.
  • Offers "Site Info" from Alexa in its results: the results offered after a particular search are accompanied by a small icon "site info". This icon works like Alexa, activates a layer with information about the page (position in the ranking of Alexa, links to the page download speed, etc.)

No creo yo que Udi Manber esté muy satisfecho con el nuevo A9. Manber es un especialista en algoritmos, ex “jefe de algoritmos” de Amazon, ex “director científico” de Yahoo y ex profesor de informática de la Universidad de Arizona… no lo veo como alguien que se contente con sacar al mercado un Google con algunas cosillas retocadas en superficie… Desconozco por cuanto tiempo se ha cerrado el acuerdo con Google y si hay o no dinero por medio (a parte de los Adwords, que beneficia a ambos. Los Adwords de Google también están en Amazon).

Time will tell ... but I hope that A9 will end up being the chrysalis of something better awaits us in the near future ... or maybe die trying ... we'll see.

As a curiosity: Udi Manber is the man behind the name A9, which refers to 9 letters in the word algorithm in English (Algorithm).

By the way ... the A9 URL is www.a9.com if you want to play around and find the differences regarding Google :-)

Solar sails: Science Fiction dream come true this week

A Japanese ship was launched on Monday, with two solar sails inside, to be tested in space. Something that until now was only science fiction can be reality in a few days.

(Image: Illustration of the possible form of a solar sail)

We live in a wonderful era where every day are produced dramatic advances in technology. Although I confess that when I was 20. I was convinced that at 30, live in a Martian colony (no kidding). Now that I have 30_y_algunos, I see that everything is going much more slowly. But ceases to amaze me that things like solar sails, which until recently were only a product of science fiction, is now being used to propel spacecraft.

As with the space elevatorArthur C. Clarke in his book "El Viento del Sol" (Alianza Editorial - 1987) tells us among other stories, what a race with solar sailing and what techniques should be used to go in the opposite direction to the sun or travel distances where sunbeams are weak.

In this book Clarke is clear that while the value of the energy produced by photons on the sail of a solar sail is very low, as is a continuous (and free btw) acceleration, it is sufficient for a few days after have left Earth and thanks to the absence of friction, the ship can reach 3,000 km / h with zero fuel.

As this seems Science Fiction 100%, it turns out that it is not. In today's edition of The New Scientist He explained that last Monday on August 9, 2004, a Japanese ship proceeded on the basis Uchino Space Center in Kagoshima (southern Japan) with two candles to be tested in space.

If the sails work, fuel for interplanetary navigation would be virtually unnecessary.

(Image: Another illustration of the possible form of a solar sail)

Now only missing to dispense fuel to overcome Earth's gravity ... but we fixed it already with the space elevator :-)

The theory that speaks of power over the candles, is nothing new, the theoretical basis on solar pressure was established by Maxwell in 1860 and recognized by Einstein in his work on the nature of light. Although so far no one had dared to conduct experiments in space, directly with candles (yes they had done in the upper atmosphere ... and failed).

Anyway ... I hope the Japanese candles work well!

Some clarifications:

  • Solar sails use sunlight, not the solar wind.
  • The solar wind is produced by electrons and protons emitted by the Sun when burning hydrogen. These particles are thrown at high speed through space, but contain very little energy. Solar sails, using the kinetic energy of the photons of sunlight to propel.

interesting and supplementary information pages:

  • Description of different forms of spatial navigation:
    Science fiction
  • article New Scientist which speaks of the launch of the Japanese ship.
  • Interesting article (in Castilian) about how does a solar sail.

I robot. Or how a poor job of marketing can kill a movie

For days I've been following the controversy that "I, Robot" has unleashed in the United States among the ranks of lovers of science fiction. But I refused to write about it until I have seen the film and I could judge for myself, and discern if "I, Robot" by Alex Proyas, attentive or not, against the memory of Isaac Asimov.

And the truth is no. Even if you are only guides for the trailer of the film you would think so ... and the trailer is exactly what triggered the ire of readers of Asimov.

And this time they have looked to the promotion of the film !!
Go crap !!

I bet the creators of the promotional campaign and had watched the film, nor had read any of the books by Asimov.

I can even imagine the team preparing the campaign ...
"Let's see ... we have ... Will Smith + Science Fiction + summer ... OK ... let's see ... what's the argument? ... robots threaten human ... polis against robots ... it come ... make a trailer with some spectacular images of robots against humans, ... Asimov? ... ummm ... let pamphlets with the Three Laws of Robotics (but adding a postscript type "are perfect until something goes wrong") ... okay ... that's it ... the next please? ".

Total, that after the trailers and pamphlets (in Spain have also been distributed), began a movement through the Internet, to boycott the film and apply to all lovers of Science Fiction failure to attend theaters to see the film Proyas.

Cuando vi el tráiler por primera vez, mi reacción inmediata y sanguínea, también fue la de “acordarme de los muertos” del señor Proyas, por haber utilizado el universo de la serie de los robots, a la entrañable Dra. Susan Calvin y a las 3 leyes de la robótica y al nombre de Asimov, para promover un film, que claramente (a juzgar por los tráilers) atentaba contra la memoria de Asimov. Lo que Asimov en realidad, en todos sus libros transmite acerca de los robots, no es otra cosa que simpatía hacia estos seres que por su candidez y por su voluntad de servir a la humanidad, a veces se desvían del camino marcado y dan lugar a innumerables y divertidas situaciones paradójicas.

En el universo de Asimov, las tres leyes de la robótica tampoco son perfectas, de hecho, Asimov se inventa una Ley Cero en la novela “Robots e Imperio” (“Un robot no puede realizar ninguna acción, ni por inacción permitir que nadie la realice, que resulte perjudicial para la humanidad, aun cuando ello entre en conflicto con las otras tres Leyes.”), y hasta tenemos La Fundación, donde no hay robots… (al menos, que sus habitantes sepan…). Pero tras leer cualquiera de sus libros, en ningún caso tienes la sensación de que los robots son malos y que tienen que ser exterminados.

Una vez vista la película, te das cuenta de que si bien el “Yo, Robot” de Proyas no tiene nada que ver alguna de las 9 historias cortas que recoge el libro homónimo, el espíritu final de la historia tampoco está en contradicción con el espíritu de Asimov. Sólo es la campaña de promoción de la película la que debe ser quemada, no la película en sí.

Y definitivamente, “Yo, Robot” es una película que vale la pena ir a ver. Tiene unos efectos especiales apabullantes y tiene escenas que se recordarán durante tiempo (escena del almacén de robots, con robot +1 infiltrado, y escena con contenedores llenos de robots antiguos poniendo carita de “Gato_con_Botas_de_Shrek_2”). El film de Proyas también explora temas como las grandes corporaciones y sus políticas internas, la dependencia humana por todo lo que es tecnología y los prejuicios humanos ante lo desconocido.

I'd rather not explain anything more about the film so that the reader still has not seen it can go to the movies and enjoy it ... even if you've seen the trailer ... better forget about it and enter the projection room with open mind.

(Five minutes from the end, ask yourself who the murderer ... to see if you can guess :-))

Discover how the creator of Radio Rivendell and how a radio works on Internet

Entrevista a Anders Dahlgren

Anders Dahlgren (the one in the picture), A Swede, 29, CapGemini consultant working on Sony Ericsson, is the creator of the first radio station that broadcasts music of epic fantasy genre, 24 hours a day, designed to acclimate roleplaying.

In the article: "If you're an Elf, now you have your radio station"Said the discovery of this radio station where you can listen to any time of day without interruption, the soundtracks of films like" The Lord of the Rings "and" Braveheart "or soundtracks of games like Neverwinter Nights and Warcraft III.

Following the aforementioned article, Anders has been kind enough to satisfy my curiosity about him and this fabulous radio station that broadcasts over the Internet since 2002 and has allowed it to entrevistase Noticias.com.

How did Radio Rivendell?

Well ... it began as a diversion from some friends that played a role. We had several CD's with different music we used to liven up the games. One day, I was testing a Shoutcast server and one of my friends suggested us to use this server to listen to our songs, rather than CDs. Radio Rivendell was born that day.

(Note: SHOUTcast is Nullsoft technology that lets you create online radio stations created with Shoutcast stations are automatically tuned with WinAmp [also Nullsoft].).

What is the target, your target audience?

Anyone interested in good fantastic music.

What are the sources of income of Radio Rivendell?

Mainly donations from listeners. Although all the money we receive we use it to pay the new server on which emits Radio Rivendell. So in the background ... returns to the listeners themselves. Unfortunately, with these revenues we do not cover all expenses that yields the station.

It all started as something small, and now we have become a community. Now I have to stay online, as long as listeners, but I have to find a way to reward everyone who makes it possible. Without going any further, a Finnish friend is the one who makes it possible for us now to have 200 users connected simultaneously.

How have you grown the station?

At first only were broadcasting commercial fantastic music (like "Lord of the Rings") we had on CD. But as time has gone by and more people have been known Radio Rivendell, many composers nonprofit, send me your songs. In return, our listeners can appreciate their music and they are disclosed. Now they begin to come some small record companies to offer their titles. And we have some "success stories" explained on several websites.

What makes happiest is to see who can give musicians something they deserve and have earned.

Tell us about your work outside the radio station:

For 4 years, I work as a consultant for one of the largest consulting firms in the world: CapGemini.

Generally, I am assigned to Sony Ericsson, where he developed new mobile phones.

I love work allows me to fully enjoy all kinds of gadgets! And besides, I just trying absolutely all phones are released to the market.

What do you like about the radio station?

Above all, that since has grown, people really appreciate the music that we issue. I do not receive many emails, but I get are really giving me energy to keep working hard.

Another great source of energy is when artists contact me directly and I request that their songs are issued by our radio!

Some labels, such as Waerloga Records (Swedish company), are making music compilations and we apply what songs to include in their CD's. So Radio Rivendell has begun to be a small showcase for lesser known artists. And this is precisely what I want, help all brilliant musicians that are out there that are more known.

What are you most proud of?

As I said before, above all, that artists come to me. I also like Radio Rivendell search on Google and see us mentioned in many places.

When I read that one of the artists being promoted on Radio Rivendell has sold CD's thanks to us, also I'm glad a lot.

And to finish,
where do you see yourself in 10 years?

With Radio Rivendell? Hmmm ... personally, I see vivendo me in a hot country, with beach, cheap drinks and a direct Internet connection :-)

Hopefully in 10 years, Radio Rivendell still alive and has grown tremendously. Now we have reached the 207 simultaneous listeners. Perhaps then we are the largest and Shoutcast station!
It is possible that at this time we are no longer specialized in fantastic music. Now we play some music outside the genre but it sounds good in what is our specialization. But who knows in ten years ...

My dream would be to devote full time Radio Rivendell. Now I can only devote to the station on weekends and some evenings.


That Ehlonna, goddess of forests, hear you and make your wishes come true.
