Link Shell Extension

The NTFS file system implemented in NT4, Windows 2000, Windows XP and Windows XP-64 supports a facility known as hard links (referred to herein as Hardlinks). Hardlinks provide the ability to keep a single copy of a file yet have it appear in multiple folders (directories). They can be created with the POSIX command ln included in the Windows Resource Kit or the fsutil command utility included in Windows XP. Thus, using standard Windows facilities Hardlinks can only be created at the command prompt, which can be tedious, especially when Hardlinks to multiple files are required or when one only makes occasional use of Hardlinks. Support for Junctions in standard Microsoft software offerings is even more limited than that offered for Hardlinks.

Link Shell Extension (LSE) provides for the creation of Hardlinks , Junctions , Volume Mountpoints , and Vista's Symbolic Links, (herein referred to collectively as Links) and a Folder Cloning process that utilises Hardlinks or Symbolic Links. LSE, as its name implies is implemented as a Shell extension and is accessed from Windows Explorer, or similar file/folder managers. The extension allows the user to select one or many files or folders, then using the mouse, complete the creation of the required Links - Hardlinks, Junctions or Symbolic Links or in the case of folders to create Clones consisting of Hard or Symbolic Links. LSE is supported on all Windows versions that support NTFS version 5.0 or later, including Windows XP64, Vista and Windows7. Hardlinks, Junctions and Symbolic Links are NOT supported on FAT file systems, and nor is the Cloning and Smartcopy process supported on FAT file systems.
Within this document the terms action button and action (pop up) menu are used to refer what are often referred to as the right mouse button and the pop up menu that is displayed when that mouse button is pressed (often referred to as the context menu). Recognising that people swap the usage of their mouse buttons, Microsoft refer to the primary and secondary mouse buttons. We prefer to refer the mouse buttons as the Select button and the Action button; and rather than terms such as Context Menu, Shell Menu, Right Mouse Menu we use the term Action menu.

REPORTA, SISTEMA DE DETECCIÓN DE COMPORTAMIENTOS EPIDEMIOLÓGICOS RESPIRATORIOS

REPORTA, SISTEMA DE DETECCIÓN DE COMPORTAMIENTOS EPIDEMIOLÓGICOS RESPIRATORIOS

• Desarrollado por investigadores de la UNAM, recaba información que alimenta modelos matemáticos para obtener mapas de riesgo de sectores poblacionales más susceptibles o afectados por una epidemia
• Este monitoreo por Internet, tiene hoy cuatro mil 600 participantes de todos los estados de la República

El Sistema Ciudadano de Monitoreo de Enfermedades Respiratorias, Reporta, desarrollado por investigadores de la Universidad Nacional, permite mantener una vigilancia permanente para detectar comportamientos epidemiológicos anómalos relativos a ese tipo de padecimientos en el momento en que ocurren.

Asimismo, la información que recaba alimenta modelos matemáticos con potencial para realizar mapas de riesgo de los sectores de la población más susceptibles, o que se han visto más afectados; también, hacer estudios del impacto de las medidas alternativas de control de una epidemia, fundamentales para los tomadores de decisiones.

Así se dio a conocer en la presentación del Sistema, puesto en marcha hace unos meses y que, desde su inicio, ha dado resultados favorables.

En conferencia de medios, Natalia Bárbara Mantilla Beniers, responsable del proyecto e integrante de la Facultad de Ciencias (FC), expuso que este monitoreo por Internet, en su primera semana de existencia, contó con tres mil registros provenientes de todos los estados de la República.

Con cuatro mil 600 participantes en la actualidad, se ha encontrado coincidencia entre este sistema de vigilancia epidemiológica y los establecidos por las autoridades competentes, por ejemplo, en los rebrotes de influenza A-H1N1.

El sistema, aclaró Mantilla, también permite detectar presencia de enfermedades crónicas relacionadas con la gravedad de la influenza en un paciente, como las cardiovasculares, asma o diabetes.

La científica explicó que hasta ahora, en Reporta participan sobre todo los grupos de edad entre los 20 y los 40 años, debido a que en ellos se encuentra un gran número de usuarios de Internet, con escolaridad universitaria, dedicados al estudio o la docencia.

La información que se proporciona es anónima y se estima la realización de campañas para aumentar la participación de los sectores menos representados. “Invitamos a todos registrarse en http://reporta.C3.org.mx, donde los ciudadanos tendrán a la mano un termómetro de la situación de las enfermedades respiratorias en el país”, finalizó.

Víctor Mireles Chávez, también de la FC, explicó que el sistema está basado en dos cuestionarios: uno inicial, de registro de datos demográficos y socioeconómicos, y otro rutinario, semanal, donde el usuario notifica si tuvo o no síntomas como fiebre; si la respuesta es positiva, se le hace una “evaluación” de tipo médico, y se le pregunta si ha recibido atención, los medicamentos recetados, diagnóstico, etc.

La meta, sostuvo, es rastrear no sólo la evolución de las enfermedades respiratorias en el conjunto de la población, sino relacionar los casos de individuos a determinados síntomas y a cierta historia clínica. De ahí que “se invite a todos a participar en esta fuente de datos confiable, que se actualiza cada hora”.

Magdalena Escorcia Martínez, de la Facultad de Medicina Veterinaria y Zootecnia, recordó que en el mes de abril pasado se registró un brote de influenza A-H1N1, derivado de un virus con información genética de tres especies. Se trató de la primera pandemia del siglo XXI.

Ante esa circunstancia, resaltó la importancia de los sistemas de monitoreo y vigilancia de cualquier enfermedad emergente. “Antes de que se manifestara la pandemia como tal, hubo advertencias; el virus estuvo circulando en diferentes regiones del mundo desde diciembre de 2005. Ahora se han registrado casos de miocarditis en niños infectados con A-H1N1, y la muerte de 30 personas con influenza A-H5N1 (aviar) en Europa. La meta es que no nos sorprendan situaciones como la vivida el año pasado”.

Luis Durán Arenas, de la Facultad de Medicina, exaltó la importancia de contar con otras fuentes de información, como el monitoreo ciudadano, donde la gente participa en esquemas de vigilancia, como este sistema que detecta signos y síntomas de enfermedades respiratorias; “si hubiera una epidemia por virus aviar, se identificaría y se alertaría a la población que hay un problema”.

Por último, Christopher Stephens Stevens, del Instituto de Ciencias Nucleares, dijo que hay muchos factores involucrados en la incidencia de una enfermedad como la influenza. Los retos son enormes para dar una perspectiva integral a estos problemas.

Reporta es una iniciativa que intenta captar datos de la participación ciudadana voluntaria, y donde los científicos colaboran en el mejor entendimiento de esos fenómenos, concluyó.

Ubuntu repositories for Vancouver

I find that here in Vancouver, ubuntu.mirror.rafal.ca and mirror.csclub.uwaterloo.ca are usually pretty good.

Note that if you add multiple mirrors, with the fastest one first, apt will actually download multiple packages from different mirrors if they have the same package versions available. So adding the following as mirrors (in order) may help on an initial install/upgrade, where there's a lot of packages to download:

http://ubuntu.mirror.rafal.ca/ubuntu/
http://ubuntu.mirror.iweb.ca/
http://mirror.csclub.uwaterloo.ca/ubuntu/
http://gulus.usherbrooke.ca/ubuntu/
http://mirrors.ece.ubc.ca

One final suggestion: if you've got a local fileserver, you could install apt-cacher-ng on it, point the cacher at those mirrors, and then have local caches of packages so new installs happen at LAN speeds. That's what we do here, and it works quite well.

You can use apt-cacher-ng as an apt proxy during install, so that's where this comes into play during the install phase.

Alternatively, you can forgo configuring networking during install, then configure network after boot, and do your package updates then. That may be faster than trying to download from a slow default mirror inside of the installer.

SICOTERAPIA

Se encuentran dos amigas cuarentonas después de mucho tiempo.

Una está muy jodida: El cutis manchado, el pelo reseco y canoso, los ojos marchitos, en fin dada a la chingada.
En cambio la otra está radiante, rejuvenecida, alegre, muy arreglada, etc.

Total que la primera le dice a la segunda:
- ¡¡¡Pero cómo le haces, te ves sensacional!!!

- Mira..., le dice la mujer guapa... ha sido la 'SICOTERAPIA'
- ¿¿¿La sicoterapia???

- Sí claro... voy a la farmacia, compro unos sobrecitos que dicen SICO...

¡¡¡Y busco quien me dé la terapia...!!!

Uno de pepito..

Niños, hoy hablaremos de dos de los fluidos del cuerpo humano: de la sangre y del semen.

La sangre es el combustible del cuerpo; es rica en glóbulos rojos y blancos.

El semen también es un fluido, pero a diferencia de la sangre, éste no sólo es rico en vitaminas, minerales y proteínas, sino que también es transportador de la información genética.

-Bueno, niños, ahora van las preguntas.

La maestra mira a todos los niños y piensa: 'Ni loca le pregunto a Pepito.

-A ver, Carlitos, ¿qué aprendiste sobre los fluidos del cuerpo humano?

- Este, este... no sé.

-A ver, tú Luisito.

- No sé, maestra.

-¿Pablito?

- No sé, maestra.

Así, pasan todos hasta que llega el turno del temible Pepito.

'Que Dios me agarre confesada con las barbaridades que este muchacho va a decir', piensa la mujer.

-A ver, Pepito, ¿qué aprendiste el día de hoy?

-Hoy aprendí acerca de algunos fluídos del cuerpo. Que la sangre es rica en glóbulos rojos y blancos, y el semen, por el contrario, está compuesto de vitaminas, minerales, proteínas y, además, es el responsable de transportar la información genética.

La maestra, que estaba sudando, piensa: 'Me salvé. Por fin Pepito no dijo una barbaridad'.

-En conclusión, maestra,..... continuó Pepito, concluyo que es mucho mejor y más nutritiva una mamadita que una transfusión de sangre.

  • Valley-Mexico mentoring grooms firms for growth

    By Matt Marshall
    Mercury News

    When Alberto Herrera started his own tech company in Tijuana two years ago, he was confident he had the knowledge to take on the risk.

    His team had worked at Panasonic's office in the Mexican border city and had the technical expertise to craft a new kind of wireless sensor network -- one that can be used for hotel room key cards and turn on the heating system once a customer has entered his or her room.

    But Herrera didn't have contacts with venture capitalists and didn't know how to spiff up a business plan.

    That changed last year, once his company, Medida, started working with the Mexico-Silicon Valley Technology Business Accelerator (TechBA for short) in San Jose, funded by an annual $6 million grant from the Mexican government.

    TechBA assigned a special adviser to Medida, to mentor it in Silicon Valley's arcane ways.

    The help is part of an effort by the Mexican government to jump-start its technology economy -- in part through better connections to leading tech centers like Silicon Valley and their entrepreneurial cultures and practices.

    Mexico's domestic information technology and software market totals more than $3 billion a year and has 2,095 companies, according to its economics ministry.

    Mexico exports about $400 million in technology services each year to the United States, about half in business process outsourcing, half in software outsourcing. But Mexico wants to do more than supply its northern neighbor with a cheap source of labor, says Jorge Zavala, chief executive of TechBA. ``The question is, how do we switch from low value-added services and move into information technology?''

    The goal of TechBA, he said, is to help create Mexican companies that own their own technology, and to export $5 billion in technology and other services by 2012.

    In Herrara's case, TechBA appointed a mentor -- Adolpho Nemirosky, an Argentine entrepreneur who has worked in the valley's semiconductor and telecom industries for 13 years. He had co-founded a venture-backed company, Xtreme Logic, and was eager to help others. He is paid a stipend by TechBA.

    His help has already gone a long way. Nemirosky taught Herrera how to make an elevator pitch -- that is, a two- to five-minute synopsis of his company, tailored for impatient investors. He advised him to focus on specific areas, such as sensor systems for hotels and for entertainment software. And he took Herrera to meet with some professors at the University of California-Berkeley, where Herrera was able to secure a technology adviser.

    To top it off, Nemirosky groomed Herrera to present to venture capitalists Tuesday evening at an event hosted by TechBA and an angel group called Silicom Ventures. Besides the investors, a live audience of more than 200 people looked on. And Herrara performed well enough that three of four venture capitalists invited him to talk with them further. ``I'm very pleased with him,'' Nemirosky said of his protege.

    Currently, 40 companies participate in the TechBA program, and the group recently announced its first tangible success: Mexican company JackBe. The company, which has created Web sites for Sears and Citigroup's Mexico operations, raised $6.5 million in venture capital funding in November -- the first Mexican tech company to raise venture capital from the United States, according to TechBA's Zavala.

    There are other signs of late that the U.S. venture capital market is waking to not only to Mexico, the world's ninth largest economy, but also to the fast-growing Hispanic market in this country.

    Sausalito venture firm Sienna Ventures is now raising $100 million for its newest fund to focus on the Hispanic market.

    Herrera's company, Medida, meanwhile, is expanding in the United States. It has $1 million in revenue after a year's work, 10 employees and an office in San Jose, where employees can drop in from Tijuana. Silicon Valley is a good place to develop contacts for customers, said Herrera.

    ``We've gained visibility that would otherwise be very hard to get,'' he said.

    One of his customers is XaviX, which makes interactive sports games and also has offices in San Jose. Medida provides XaviX wireless sensors for its newest fly-fishing game -- where the sensor detects when game players flick their wrists and feeds information back to the game.

    Mexico is just the latest country trying to develop a network here in Silicon Valley.

    Gadi Behar, managing director of Israeli-focused Silicom Ventures, has reached out to groups from Canada, Argentina, Brazil, the Netherlands and Hawaii, offering help such as crash courses on Silicon Valley's business culture. ``They all want access to Silicon Valley,'' agreed Michelle Messina, a public relations professional who has also helped companies in these groups.

    Digg, Memeorandum, Findory, Blogniscient, and other startups promise to manage news overload on the Web.

    Few would dispute that we live in an age of information overload. In the last few years alone, blogs have increased the torrent of information each day to unmanageable levels.
    This would explain, then, why a corresponding torrent of startups has surfaced recently to help us filter, manage, and control this flood of information. Some rely on insightful algorithms that understand popularity to filter the news, while others rely on the preferences of readers.
