OpenCV 2.4.x over Ubuntu
[1], is best for me, have scripts for install opencv library, if you like more details about steps, is possible use [2] or [3].
-----------------------------------------
When you like java libraries
Need to do[4]:
$ export JAVA_HOME=/root/jdk1.7.0_07
$ mkdir build
$ cd build
$ cmake -DBUILD_SHARED_LIBS=OFF ../
If you get this message: libv4l2.so.0: error adding symbols: DSO missing from command line collect2, do that:
$grep -rl -- -lv4l1 samples/* modules/* | xargs sed -i 's/-lv4l1/-lv4l1 -lv4l2/g'
If not works, start again using [5].

Grasa Corporal, omron, plicometro
Con cada uno es un mundo, y si te la mides hoy, no te da lo mismo que mañana...
Yo opte por utilizar un metodo que me dijo alguien en el gimnasio..
"...Tu mirate al espejo y si te ves de puta madre, tienes mejor estado fisico.. corres 4 kilometros o los que sean, estas bien contigo... que mierda importa la grasa?¿.."

Package opencv was not found (CentOs 6.5)
Package opencv was not found in the pkg-config search path.
Perhaps you should add the directory containing `opencv.pc'
to the PKG_CONFIG_PATH environment variable
No package 'opencv' found
Solution
1) find opencv.pc
$ locate opencv.pc
/mnt/vol3/installers/opencv/opencv-2.4.8/build/unix-install/opencv.pc
...
/usr/local/lib/pkgconfig/opencv.pc
2) then add to enviroment variable the path
$ export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig/

Registros DNS (DNS Registers)
Estos se utilizan para traducir los nombres de dominio en direcciones IP.
AAAA (IPv6) Record:
El registro de la dirección IPv6 es un espacio de direcciones mucho más grande que el de un registro de la dirección IPv4. Las direcciones de registros de direcciones IPv6 tienen 128 bits de largo, mientras que las de IPv4 registros de direcciones tienen 32 bits de longitud.
Cuando usted recibe su nombre de dominio con una empresa de hosting, usted contará con una dirección IPv4 o una dirección IPv6. Esto necesita ser configurado como un registro o un registro AAAA respectivamente, para que el nombre de dominio en particular. Con Abaco Hosting cuenta con un panel de control detallado con estas funciones. Evite el registro de dominio con empresas terciarias que no le permiten el manejo de su zona dns.
Mail Exchanger (MX) Record:
Un registro MX identifica el servidor de correo electrónico (s) responsable de un nombre de dominio. Cuando se envía un correo electrónico a usuario@dominio.com, su servidor de correo electrónico debe primero busca el registro MX para sudominio.com a ver qué servidor de correo electrónico en realidad se encarga de correo electrónico para sudominio.com (esto podría ser mail.sudominio.com o algún otro correo electrónico servidor como mail.isp.com). A continuación, busca el registro para el servidor de correo electrónico para conectarse a la dirección IP.
Un registro MX tiene una serie de preferencias, lo que indica el orden en que se debe utilizar el servidor de correo electrónico. Servidores de correo electrónico intentará entregar el correo electrónico al servidor con el número más bajo de primera preferencia, y si no lo consigue continuar con el más bajo, y así sucesivamente.
Canonical Name (CNAME) Record:
Los registros CNAME son alias de nombres de dominio. A menudo los ordenadores en Internet tienen múltiples funciones como el servidor Web, servidor FTP, servidor de chat, etc. Para ocultar esto, Registros CNAME se puede utilizar, por poner nombres de los equipos individuales múltiples (alias).
A veces las compañías registrar varios nombres de dominio para sus marcas de fábrica, pero todavía desea mantener un único sitio web. En tales casos, un registro CNAME tal vez puede utilizarse para reenviar tráfico a su sitio web actual.
Ejemplo:
www.sudominio.com podría ser CNAME para www.sudominio.net.
El uso más popular del Registro CNAME, es facilitar el acceso a un servidor Web que utiliza tanto la norma www.yourdomainname.com y yourdomainname.com (sin www). Esto suele hacerse mediante la adición de un registro CNAME para el nombre www apuntando al nombre corto [al crear un registro A para el nombre más corto (sin www)].
Los registros CNAME también se puede utilizar cuando un equipo o servicio tiene que ser renombrado, para permitir temporalmente el acceso a través de tanto el nombre antiguo y nuevo.

Notes:
If you mean MS-DOS then there's only
FIND
, as far as I know. But it's an ancient OS not used anymore.If you mean NT(XP/2K/7/Vista)'s Command Prompt you can use
find
, findstr
and grep
if you download GnuWin32.The basic differences are that findstr has some regex support. Grep supports regex best.
