Mapa de visitas

This plug-in will grab your visitors IP address and generate a Google map with markers on those visits. You will need a valid Google API key in order for this to work. – Este plug-in guarda la dirección IP de tus visitantes y genera un mapa (Google) con marcadores para dichas visitas. Necesitas una clave válida de Google API para que esto funcione.

• Download the plug-in from WP plug-in page
Descarga el plug-in desde la página de plug-in de WP

• Upload the plug-in folder into your plugins directory
Sube la carpeta del plug-in a tu directorio de plugins

• Install te plug-in in the usual way and set your configuration through “Options/Visitor maps by IP”
Instala el plug-in de la manera usual y configuralo desde la página de opciones en “Opciones/Visitor maps by IP”

• Insert the plug-in in your template pages using:
Inserta el plug-in en tu página (template) con este código:

<?php
    if(function_exists('ip_tracker_draw_map'))
        ip_tracker_draw_map();
?>
  • If you want to insert the plug-in in your template but don’t want to show the map use this:
    Si quieres insertar el mapa en tus plantillas pero no mostrar el mapa, utiliza esto:
<?php
    if(function_exists('ip_tracker_draw_map'))
        ip_tracker_draw_map('track_only');
?>
  • You can also insert maps into your posts. In your post simply use any of the identifiers provided to render the map at any given place. Valid identifiers are: [vm] [visits] [visitormap]
    Desde la versión 0.4.8 también se pueden insertar los mapas en las entradas. Para insertar un mapa en una entrada, simplemente utiliza uno de los identificadores en un lugar determinado.

If you have any problems or find a bug, please let me know.
Si tienes algún problema o descubres un fallo, por favor dímelo.

Please look at the plug-in page at WP and/or the plug-in options page for details.
Por favor mira la página del plug-in en WP y/o la página de opciones del plug-in para detalles.

Current release / Versión actual: 0.7.3
Version history / Histórico de versiones:

This plug-in requires PHP 5 on your server
Este plug-in requiere PHP 5 en tu servidor


Please keep in mind that this plug-in uses geo-ip location information (GeoLite City) provided by MaxMind, which is limited to some extent, this means it will not track down your exact address (location of your IP number) but it will show the city your visitors are coming from which works just fine for me.
Por favor recuerda que este plug-in utiliza información para geo-localización (GeoLite City) gracias a MaxMind, la cual está limitada hasta cierto punto, esto significa que no es capaz de detectar tu dirección exacta en base a la IP, pero si es capaz de mostrar la ciudad de donde vienen las visitas, lo cual funciona muy bien para mi.

GeoLite City is similar to the GeoIP City database, but is less accurate. Should you require greater accuracy, GeoIP City is a drop-in replacement for GeoLite City. GeoLite City is an ideal cost-effective solution, since it is more accurate than many other commercial geolocation solutions.

The free version -which this plug-in uses- gets updated each month, so I will update the plug-in as well -at least each month- so you can have the latest IP information.
La versión gratuita -la cual utiliza este plug-in- es actualizada cada mes, de modo que actualizaré -al menos cada mes- el plug-in para que puedas tener la información más reciente.

Next releases:
Próxima versiones:

  • Be able to upload / define a custom icon for markers Done
    Posibilidad de cargar / definir un marcador propio Hecho
  • Set number of markers to display (limit query) Done
    Definir el número máximo de marcadores a mostrar (limitar la consulta)     Hecho
  • Small JS fix in the options page (on marker select) Done
    Resolver un pequeño error de JS en la página de errores (al seleccionar un marcador)     Hecho
  • Be able to insert maps into posts and pages (not through templates) Done
    Posibilidad de incluir un mapa en las entradas (no solo a través de la plantilla)     Hecho

A comment would be much appreciated.

Memory trick breaks PC encryption

marzo 5th, 2008 Posted in English

Encrypted information held on a laptop is more vulnerable than previously thought, US research has shown.

Scientists have shown that it is possible to recover the key that unscrambles data from a PC’s memory.

It was previously thought that data held in so-called “volatile memory” was only retained for a few seconds after the machine was switched off.

But the team found that data including encryption keys could be held and retrieved for up to several minutes.

“It was widely believed that when you cut the power to the computer that the information in the volatile memory would disappear, and what we found was that was not the case,” Professor Edward Felten of the University of Princeton told BBC World Service’s Digital Planet programme.

Volatile memory is typically used in random access memory (RAM), which is used as temporary storage for programs and data when the computer is switched on.

Deep sleep

Disc encryption is the main method by which companies and governments protect sensitive information.

The key to making it work is to keep the encryption key secret, explained Professor Felten.

Encryption has recently become a hot topic after a number of laptops containing personal records were lost or stolen.

What we have found was that the encryption keys needed to access these encrypted files were available in the memory of laptops, he said.

“The information was available for seconds or minutes.”

In theory, this is enough time for a hacker or attacker to retrieve the key from the memory chips.

The real worry is that someone will get hold of your laptop either while it is turned on or while it is in sleeping or hibernation mode, said Professor Felten.

In these modes the laptop is not running, but information is still stored in RAM to allow it to “wake up” quickly.

“The person will get the laptop, cut the power and then re-attach the power, and by doing that will get access to the contents of memory – including the critical encryption keys.”

Cool running

Switching the machine off and on and is critical to any attack.

When it comes out of sleep mode the operating system is there and it is trying to protect this data, explained Professor Felten

But a full power-down followed by a swift re-start removes this protection.

“By cutting the power and then bringing it back, the adversary can get rid of the operating system and get access directly to the memory.”

Professor Felten and his team found that cooling the laptop enhanced the retention of data in memory chips.

The information stays in the memory for much longer – 10 minutes or more, he said.

For example, where information stays in a computer for around 15 seconds under normal conditions, a laptop cooled to about -50C will keep information in its memory for 10 minutes or more.

Professor Felten said that the best way to protect a computer was to shut it down fully several minutes before going into any situation in which the machine’s physical security could be compromised.

Simply locking your screen or switching to ‘suspend’ or ‘hibernate’ mode will not provide adequate protection, he added.

“It does cast some doubt on the value of encryption. I think that over time the encryption products will adapt to this and they will find new ways of protecting information.”
