It's hard to believe that Linux can be news, because what you usually see are versions and versions of the same, but this time I was surprised a new design, layout and when I say I say this from inside, as Asturix, although based on UBUNTU and the next version "Asturix 4" next to leave before the end of the year will have a new desktop, very light, fast and reliable, created XHTML5, Javascript, C + and some PHP, changing everything we know today. With the full support of Maddog, currently president of Linux International.

I can say that this is a breakthrough in terms of free software is known, allowing more people every day coming into the world.

I recommend that you not proveis disappointed, and I say from the depths of my knowledge, as of this week belong to the design group, supporting the project in what I allow my knowledge.

For my part, of course, I have it on the computer of the girl and in my MacOSX with Parallels.

Scheduled expiration, or rather why more and less durable appliances and electronic equipment ...???

lamps that last x hours ... or printers that print x copies ... because you can not really do something that will last decades.??? as antoaño all products ... my grandparents had things daurada almost a life ... not to mention cars, if you have a FIAT over 10 years, and is falling apart ... and the old CHEVY / FORD / CITROEN keep rolling the roads ...

But until recently but I had an amplifier balbulas that worked better than any current computer.

Here's an example that you can, a lamp that is turned on since 1901 (well so they say), but can be seen burning on the internet, and have burned 3 webcam, but the lamp still on.

Here the original link ... http://www.centennialbulb.org/cam.htm

After watching a movie name (Into Eternity), I am scared enough ... seeing how we are killing ourselves little by little with so much crap that we generate. On the other hand surprised because I find that watching a movie, there's so much nonsense on television and nobody has mentioned, at least I have not seen ...

After investigating and I have more information, is a tunnel 400 meters deep at its deepest galleries will be constructed to house nuclear waste, the first test gallery will be ready in late 2012, when they began to fill all the galleries, while fill the company will continue building more and more galleries, to complete the project, about 2100, when all the galleries are full, is thought to seal the tunnel with cement, and place monoliths around the tunnel to warn of what exists in the land to anyone in the future try to dig there ...

For now the only information I see is a note in Spanish Terra ... but so little I announced, perhaps the people of "green peace" should do something ... do not know.

Here you have more information link to the topic that interests you ...

This is the company that makes the project:

Posiva http://www.posiva.fi/en/research_development/onkalo/

And an animation project http://www.posiva.fi/en/research_development/onkalo/

This is a picture of the project to end in 2100 (but is expected in 2012 having completed the test gallery and begin saving garbage)

It is assumed that 2100 is the date that is full of rubbish and completely seal the tunnel with concrete.

It has long amazed me by the signal so strong that I have on the phone, now I understand why ...
Just camouflaged and concealed antenna I have seen a phone, needlessly hidden inside a mesh cylinder which I guess is colored plastic to cover metal ... thinking a little ... because I can not think that is not nothing but a phone masts ... radiating to the face ...
And to give me more to think, just a building rented by the Banco Santander, where there are no owners, only weekly rentals.

Well I put the pictures you draw your conclusions.

This is mostly a memory aid, not having to search online or in the oracle. These circuits are tested and if you follow the scheme correctly you get good results.

Here is how to connect switches or buttons, either for positive or negative ramp.

We also see how to connect an LM35 thermostat.

Recall that this transistor has a large measurement range, with a definition of 10mVolts by grade.

Can measure from -55 º to 150 º C operating at voltages from 4 to 30Volts. With only 4 volts peak can measure it would be 150 ° C.

If we get for example:

In our reading of 1.5 volts output is +150 ° C

If you have serious reading 0.25 Volts to +25 º C

And the next end is -0.55 volts would represent at -55 ° C

Here is an infrared sensor, which works perfectly.

Check with your building diode receiver has to be negative to the positive pin, or connected to 47K resistor.

Finally we like to connect a simple LED (considering a 5 volt supply).

LDR also one which gives a positive output pulse inverted, or negative ramp.

Later I will make the programs to use each.

Here's a project I've been trying to finish time, and eventually I did.

REMEMBER IT IS A PROTOTYPE, NOT A MODEL OF PRODUCTION.

After the news of so many fires in many parts of Europe, I thought that maybe if we had an early warning in each case, can control the fire more efficiently. For example, if my idea, XBee sensors WIFI technology which provides a range of 1500mtrs to each node, we could put one of these sensors in an area bounded by 1000mtrs sectors, these sensors communicate with a wireless technology and cascade can work, moving and routing all messages to a common point, which might be an alarm center.

Each would have its GPS sensor stored in the alarm message every 30 seconds and controlled levels of temperature and infrared emission, to detect a significant difference between readings, could warn well in advance where fires occur, and each sensor may have minimal maintenance, and that would be self powered by a battery charged by a solar panel.

Basically these sensors consume only to send the signal staying asleep during the rest of the time. So the battery would last many days in low solar load.

I think it's a very good idea and can help you keep so many forests and parks. An additional point could be the safety of these modules, but I think introducing each sensor in a pipe embedded in the earth, and solar cell just by looking (and this at a considerable height) could prevent theft or destruction.

Another point to seriously consider what is feasible and inexpensive product, which could be built for less than 90euros, in cases of massive orders clear.

The prototype is as follows, as you can see has a solar panel for testing actually works correctly but need something bigger, always depending on the performance and the incidence of sunlight. This sensor has a sealed housing that protects it from rain and lower output for infrared sensors and temperature.

Here we see the household goods received by the computer in charge of organizing and identifying the alarms. To his right the receiver XBee protocol, this is connected via USB to any computer and receive wireless signals a distance "without hindrance" of 1500mtrs, has a power of 60mW.

Here we see the present in the sensor module, which has adapted to connect to the micro controller, which makes all the magic.

Below this you can see the PIC board, and lithium battery 3.7 volts generally required for the set.

Here is the set without the packaging.

Here if we separate the parts we can see the Micro controller, which is who captures and sends data via serial XBee to be transmitted to later.

Here we see more clearly the two plates.

The important thing is the project that provides low power transmitter XBee, and intelligence possessed by the micro controller, since this is responsible for data capture, process and send them via the communications port.

For the general case consumption is 100mA continuous communication, but if you configure it to only make shipments every 30 seconds and the rest of the time is asleep, miserably low consumption to 30mA, offering an interesting range.

The first tests with the battery installed I've only had a duration of 10 hours continuous transmission, which I think would be enough, if we had cloudy days and the solar panel could charge batteries daily, but in the case of a cloudy day would not be useful.

Now if we lower the consumption sleep settings can extend to 30hora of autonomy, and that is not enough, because I have lived weeks of cloudy weather, so I need to find a solution for batteries or solar panels with a little more performance.

Con este tuto pretendo que la gente como yo que tenemos un IPHONE de los viejitos (SNIIFFFF, SNIIIFF) con poca memoria RAM, podremos ver como fluye libre el Nuevo iOS 4.X. A una velocidad respetable.

En mi caso e instalado esta versión del iOS para el IPHONE, y le he quitado la opción de multitarea… pero ya lo he probado con esto activo y funciona mucho mas decentemente. Le he quitado la opción de multitarea para no tener que acordarme de quitar de memoria a los programas que ya no uso, porque hubo casos que he encontrado programas en memoria que hacia 3 semanas no usaba, y los recursos que consumen me parecían un desperdicio, por ende decidí quitar la opción de multitarea pero para gustos los colores y cada uno haga lo que quiera.

Siguiendo en el tema, sin la multitarea y con el parche activado mi teléfono funciona a las mil maravillas… y no se queda en ningún momento sin memoria, lo menos que he tenido fue cerca de 20 megas libres… nunca menos…

Básicamente el parche consiste en un archivo “.plis” serian como los scripts normalitos de LINUX, el cual le indica a nuestro IPHONE que reserve una cantidad de memoria flash, para utilizarla como memoria RAM, una especie de PAGEFILE.SYS de Windows.

Necesidades previas:

Como es lógico necesitamos acceso al directorio interno de nuestro IPHONE, asi que mediante CYDIA instalaremos el servidor SSH, con esto obtendremos acceso SFTP al disco de nuestro IPHONE. Adicionalmente como es lógico necesitaremos un programa en nuestro ordenador que pueda hablar SFTP con el teléfono, os recomiendo FILEZILLA .

Y a continuación solo deberemos descargar el archivo desde este LINK, es privado y libre de virus. La clave del archivo es “walii.es” sin comillas.

Con el programa FileZilla, nos conectamos a nuestro teléfono y transferimos el archivo descomprimido, solo el archivo con nombre “ com.apple.dynamic_pager.plist “, no transferir el RAR.

Este archivo debe quedar alojado en el siguiente directorio:

System/Library/LaunchDaemons

Esta es la captura para saber cuánta memoria teníamos antes de aplicar el parche….

Después de cerrar todos los programas y limpiar el cache, tenemos solo 37MB de RAM.

Tras reiniciar (apagar y encender) el teléfono con el parche en su sitio, tenemos una memoria de 87MB, que

dejando se estabilice con los programas normales, teléfono, ipod, mail, etc. Nos queda cerca de 50MB.

Con esto comprobamos como ha mejorado notablemente la velocidad de nuestro teléfono y si verificamos con pruebas el antes y después, ganamos varios segundos en las velocidades de apertura de programas pesados, como el TOMTOM o NAVIGON.

Información adicional y útil para nuestro IPHONE.

Greetings.

HOla… quería dejar nota de esta configuración para poder recuperarla en cuanto la necesite, y para que la gente la tenga a su alcance.

Es una configuración BRIDGE, esto quiere decir que se conecta a la VPN, y una vez conectado se le asigna una IP del mismo rango que la red destino, y para todo funcionamiento lógico, es como que esté conectado con un cable muuuuy largo a su red privada. Pudiendo imprimir en sus impresoras, mirar sus discos de red o también jugar en red, desde cualquier parte del mundo como si estuviese conectado con un cable en su red de área local.

Se necesitan varias cosas:

Instalamos el OPENVPN:

Opkg update

Opkg install openvpn

Instalamos los manejadores de compresión:

opkg install liblzo

Creamos una llave para ser distribuida entre los clientes que deseen conectarse:

En este caso lo llamaremos “secret.key”:

Openvpn –genkey –secret secret.key

Y la ponemos en el directorio que corresponda… (Mirar la configuración del openvpn)

Creamos un iniciador del túnel, este archivo lo creamos en el directorio /etc/init.d con cualquier nombre por ejemplo openw

Ahora por ultimo crearemos una configuración para nuestro túnel (recordemos que todo lo que está detrás de “;” no aplica a la config es solo descripción:

Hay que verificar la posición de todo lo necesario… por ejemplo el archivo de logs y el secret.key tienen que estar en el camino correcto.

Por último lo que necesitamos es crear un script que inicie la interfaz de túnel, y que cree todo lo necesario para nuestro túnel.

Este archivo puede llamarse: “startupscript”

Lo creamos, y ponemos dentro lo siguiente:

Son unas pocas líneas, porque he filtrado todo lo que no necesitamos.

Esto genera que cuando conectemos, verifica la firma digital del archivo secret.key y nos asigna una ip de la red privada.

Para poder conectarnos necesitaremos una configuración del cliente, y copiar previamente la forma digital al directorio config, de nuestra instalación (Windows/Linux)

La config de cliente será la siguiente:

Listo ya podríamos conectarnos. Si necesitamos información extra, podemos ver el log del servidor con el comando “logread”. Y consultar la información en el link de OPENVPN http://openvpn.net/index.php/open-source/documentation/miscellaneous/88-1xhowto.html Saludos.
