Update kernel to the latest mainline version without any Distro-upgrade?

To find out which kernel you have type uname -rin terminal.Now type this command to get list of available kernels.

apt-cache search linux-image

this will give you a very big output.Now chose one of them that you want to install and install it by following commands(Don't type these commands like this,replace the word kernal_version with the kernel version which you wish to install)

sudo apt-get install linux-image-kernal_version
sudo apt-get install linux-image-extra-kernal_version
sudo apt-get install linux-headers-kernal_version

Now in my case i choose linux-image-4.10.0-22-generic so my command will look like this

sudo apt-get install linux-image-4.10.0-22-generic 
sudo apt-get install linux-image-extra-4.10.0-22-generic
sudo apt-get install linux-headers-4.10.0-22-generic

now in the end remove old kernel by command

sudo apt-get autoremove

sudo reboot

Español

'A ver' y 'haber' se pronuncian de la misma forma, pero es habitual confundirlas y utilizarlas de manera incorrecta a la hora de escribir. Por eso, a continuación procedemos a distinguirlas tal y como marca la Real Academia Española (RAE):


A ver: Se trata de la secuencia constituida por la preposición a y el infinitivo verbal ver. Se utiliza en los siguientes casos:
        Para pedir al interloculor que nos deje ver algo: - Mira mi coche. - ¿A ver?
        Para dejar claro una cierta expectación: A ver cuándo viene la ayuda.
        Para llamar la atención sobre algo: A ver, ¿por qué no no vinisteis ayer a casa?
        En los casos en los que equivale a 'claro' o 'naturalmente': ¡A ver! Estaremos allí sin falta.
        En los casos que lleva delante la conjunción si, expresa, bien expectación, curiosidad o interés, a veces también un reto; otras temor o sospecha; y deseo o mandato: ¡A ver si me traes lo que te he pedido!

Haber: Puede tratarse de un verbo o un sustantivo:
        Como verbo se emplea como auxiliar seguido de un participio, para formar los infinitivos compuestos de la conjugación: Debe haber faltado a clase.
        También como verbo se emplea como infinitivo del impersonal que indica la presencia o existencia de lo designado por el sustantivo que lo acompaña: En su casa debe haber mucho dinero.
        Como sustantivo masculino su significado es "conjunto de bienes o caudales de una persona": En su haber contaba con muchos títulos.

        qtwebkit is needed by skype-4.2.0.13-fc16.i586  

then i tried next commands and works very well. 

1) Install EPEL if you haven't already.
#yum install http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm

2) Download the RPM here
#wget http://www.bromosapien.net:8080/others/skype-4.2.0.11-4.el6.i686.rpm

3) Install it as so
#yum install skype-4.2.0.11-4.el6.i686.rpm

4) If you receive an error about a GPG key, you may import my key as necessary.
#wget http://www.bromosapien.net:8080/others/SYRKIT-GPG-KEY.pub
#rpm --import SYRKIT-GPG-KEY.pub

Bag of Features and Texture

Notes

What is the difference between SIFT and Dense SIFT

*SIFT consists of both detection and description while dense sift only uses the descriptor in densely sampled locations [1].

*SIFT identifies interest points using Difference of Gaussian Filtering (DoG) before using Histogram of Oriented Gradients (HOG) to describe these interest points, however Dense-SIFT does not identify interest points, it simply divides the image into overlapping cells before using HOG to describe them. since they both use HOG they both produce 128 dimensional feature vectors [1].

*SIFT is typically computed at interest points. Dense SIFT is computed at every pixel, or every kth pixel. HOG is computed for a rectangular cell array where each cell is usually 8x8 pixels. Dense SIFT and HOG are similar in the sense that they both characterize edginess and orientation around pixels, but the computations are different. Jianxiong Xiao's 2x2 HOG is different than normal HOG. The truth is that once you know how these kinds if features work you can get fancy and histogram them differently, change normalization terms, etc and create your own variant. I spoke with Prof Xiao many times about this when we ovarlapped at MIT [2].

*Firstly, Difference of Gaussians (DoG) can be used for estimating Laplacian of Gaussians (LoG), which are useful for finding edges and blobs. DoG is computationally faster so it is used. Overall, the way in which LoG is used for SIFT and HOG is the fundamental difference between these two feature descriptors. Dense SIFT is exactly as it sounds, SIFT computed densely for every pixel in the image and it helps in image registration, pose estimation, object recognition, etc [2].

Como viajar de Perú-Arequipa a Brasil-São Carlos

Técnicamente es posible, e imagino que a mayor experiencia se puede optimizar tanto tiempo como dinero.

Generalmente te colocan solo los puntos y precios, pero hay detalles que aveces te pueden hacer perder tiempo, dinero y la paciencia. Espero esta descripción les pueda ayudar.


Inicio en el terminal terrestre de Arequipa de madrugada un jueves de enero, hay varias empresas de Arequipa-Juliaca, yo usé San Roman (20 Soles) dado que es el mas seguro, aunque demora un poco 4 a 4:30hrs.

Llegando a Juliaca, una moto taxi hacia el "Terminal a Puno" lo mejor es tomar un Omnibus hacia Puno (2 Soles) 1hr. Posteriormente llegando a Puno puedes tomar un Taxi(4 Soles) al "Terminal a Desaguadero", evidentemente tienen su nombre pero asi lo indicas y el taxista comprenderá perfectamente.
Ese terminal es por demanda, es decir bus lleno, bus que parte.

Camino Puno-Desaguadero

De Puno a Desaguadero te cobran 8 Soles sentado, parado 5 Soles y demora unas 3hrs.
Llegando a la frontera: Aquí desembarcas del ómnibus y sigues a la gente, al pasar los segundos veras el puente de frontera y además a los cambistas en unas mesitas pequeñas yo cambie 250 Soles que hacen unos 518 Pesos Bolivianos aquel dia.
Seguidamente te diriges a Migraciones(Perú) donde debes pedir tu hojita  la llenas y haces cola para sellar la salida en tu pasaporte, recomiendo llenarla en la misma fila, ya marcaban casi las 6pm, hora en la que cierran frontera normalmente.

Puente Perú-Bolivia (Vista desde desaguadero)

Cruzas a pie sin problema el puente Perú-Bolivia(Adiciona una hora a tu reloj), es probable que veas policías de Bolivia ni los mires, solo sigue a la gente ni les preguntes nada, yo lo hice y me llevaron adentro a abrir mi maleta y revisar mis cosas estuve 1hr atrapado. Al entrar a territorio boliviano hay dos calles divido por un edificio(migraciones de Bolivia) el control/puesto se encuentra a la izquierda(tu izquierda).  De la misma forma pides tu hojita que es verde en este caso en una ventanilla externa, la fila mas larga esa es para sellar entrada a Bolivia, así que aquí mínimo consumirás unas dos horas(paciencia).
Luego sigues en la misma dirección que ingresaste a territorio boliviano y notaras unas combis hacia la Paz,  ellos te cobran 15Bs y demora unas 2hrs.

En la Paz, es posible tomar un bus hacia Santa Cruz directo o en dos tramos, aveces por el horario no encuentras, yo lo hice en dos tramos. Tomé el bus a Cochabamba(Empresa El Dorado) que salia a las 10:00pm y demoraba 8hrs a 40Bs o 70Bs, depende del servicio. Yo tomé la segunda opción, sin embargo dada la comodidad de los ómnibus la próxima vez, tomare el de 40Bs por solo 8 horas no compensa mucho pagar casi el doble.

Ya en el terminal de Cochabamba, me sorprendí ver un cajero BCP, espero funcione me quedé con las ganas de usarlo, salí del terminal a tomar desayuno un Café, Pan y Queso, literalmente es eso (es decir el queso no viene dentro del Pan) a 10Bs. Dentro del terminal hay varias empresas que van a Santa Cruz desde 70Bs+2.5Bs por uso de Terminal, demora unas 10hrs. Partí como a las 7:15am(Ojo con el horario del terminal). Y es normal hacer parada en algún restaurante a la hora del almuerzo.

Durante el camino a Santa Cruz notaras el paisaje selvático, además de los controles policiales bajaras unas dos veces(control antidrogas). Una vez llegues al terminal notarás que es absolutamente desordenado e informal sin mencionar la calor(Enero). Hay gente que toma el tren de la muerte hacia Quijarro, en mi caso cuando llegué un Viernes el tren ya había salido a la 1pm, así que decido tomar otro ómnibus que demora unas 9hrs y cuesta 80Bs hasta Quijarro.

Horario Tren

Al llegar a Quijarro 6-7am(en Puerto Suarez), debes tomar un taxi/colectivo hacia la frontera (10 Bs), llegando vi una fila larga en migraciones del lado de Bolivia, entonces decidí caminar en el mismo sentido del puente limite en busca de las empresas de ómnibus Andorinha que hacen ruta directa Frontera-São Paulo, lo que no vi fueron unos letreros de duchas, cuando llegué no me fije y fui a un hotel 60Bs y me quedé un día en frontera(Esto fue el sábado). Si hubiera visto las duchas hacia lo propio y continuaba(para la próxima).
Una vez dormido por la mañana almorcé y fui a frontera a ver que tal estaba la fila como a las 4pm, y aún tenia tiempo por que cierran a las 5pm, hice poner el sello y solo me faltaba pasar la noche y al día siguiente cruzar la frontera.

Yo nunca imaginé que podías marcar entrada de Bolivia e ingreso a Brasil y aún así dormir en Bolivia, es decir regresar a territorio de donde ya saliste(para la próxima).

Quijarro - Frontera Bolivia-Brasil

Debí levantarme a las 5am(Domingo) para formar fila, pero fui a las 7am y las consecuencias fueron 8hrs en frontera para registrar mi ingreso a Brasil + 3 botellas de agua 15Bs (5Bs/botella) y el tráfico de fila, no hable con nadie aprovechan el dialogo para meter gente lo cual extiende la fila previa a ti.


Cruzando la frontera hay un ómnibus que pasa casi a cada 45min a 3.25R, yo tomé el de las 4pm(para que se hagan idea lo que demoré). Ese bus llega a un terminal local y tienes que hacer trasbordo a otro(Cristo Redentor) que es el que te lleva al Terminal de Corumbá(sin pagar nada adicional), ya en el Terminal de Corumbá puedes usar tu cartón del Banco de Brasil si tuvieses para pagar. Intenta no comprar nada; gasté 17R en 2 salteñas(salgados) y una Fanta.

Entonces aquí ya puedes comprar tu boleto hacia Campo Grande, irónicamente la empresa dominante es Andorinha, consulta [1] para los horarios.  Costo de viaje 114R y salia a las 18.30pm con una demora de 9hrs. El  Terminal Rodoviario de Campo grande es agradable similar a un aeropuerto, muy bueno desde mi punto de vista hasta dormí en la bancas, no había remedio atienden desde las 5 o 6am, compré mi ticket de Campo Grande a São José de Rio Preto para las 8am a 134R con un tiempo de 11hrs de viaje. En este tramo subirán los de la Policía Federal dos veces y te preguntarán de donde vienes? a donde te diriges? por que? etc, etc.

Finalmente en el terminal de Rio Preto un lugar con mucha antigüedad, compré un ticket a São Carlos para las 11.45pm a 60R y por fin las últimas 4hrs.

Llegando a São Carlos a las 4am un amigo me recogió, aunque a esa hora ya hay bastante gente y puedes esperar a clarear para usar el transporte local también.
