Los virus son programas maliciosos que infectan las computadoras sin el permiso del usuario y pueden causar daños como destruir datos o ralentizar el sistema. Se alojan en programas y archivos para propagarse a otros cuando se ejecutan. Existen diferentes tipos de virus como gusanos, bombas de tiempo, caballos de Troya y virus polimórficos. Para protegerse, es importante mantener el antivirus actualizado y usar un firewall.
When you're getting to know (and love?) Drupal 8, you might hear a lot of words that you pretend to understand. It's OK, just check in here for the down-low on those headscratchers. This lesson in Drupal 8 vocabulary covers these fun phrases...
- YAML
- Composer
- PSR-0
- Dependency Injection
- Service Containers
- Routing
About a year ago, I started feeling overwhelmed with all the changes to front-end development. I understood HTML and CSS, responsive design made sense, but then everybody started grunting and gulping, and frankly I got a little scared. Wasn't Bower the arch-enemy of Mario and Luigi?
Combine that with all the changes to Drupal 8, and it's pretty easy to feel overwhelmed. Everybody else knows what all these new things are, right? I'm the only one in the dark?
What made me most nervous was not even knowing what all these terms mean. Once I had a basic grasp of a concept, it felt a lot less intimidating.
So what I'd like to share with you is a Drupal 8 base theme I'm developing that uses some of these new techniques. I'm not going to explain to you the details of how to implement every single new technique out there, but will try to explain what some of these new tools are without making too many assumptions of what you might know. I will walk you through the structure of a Drupal 8 theme that makes use of new front end techniques, so you can see what does what and get some ideas of what you'd like to learn next.
My goal with this theme is to make use of Brad Frost's atomic design principles: essentially component based design. I'm setting up this theme to integrate with Pattern Lab, a prototyping tool that we'll also set up to work as a living style guide. Styles are managed with Sass and synced with Pattern Lab using Grunt, a task manager. The theme makes use of a number of great Sass tools like Breakpoint and the Susy grid framework. We'll also take a look at the Twig templates new to Drupal 8, as well as some of the other theme files specific to Drupal 8.
I hope that I'll learn from you too. If we have time during Q and A, you can share some modern techniques you'd like to see in a new Drupal theme. There's a good chance I'll be working on the theme during sprints, so if you'd like to help pitch in, I'd be glad for the assistance. This theme will be featured in my upcoming book: Drupal 8 Responsive Web Design.
My goal is for us all to leave the session feeling that while we may have to learn, we have a handle on what front end techniques look interesting and useful to investigate further.
When my session finishes, my goal is for attendees to leave the room more familiar with the files they are likely to see in a Drupal 8 theme, and what each of them does. Similarly, attendees should have a greater familiar with the some of the newer techniques and tools they might encounter in a Drupal 8 base theme.
The configuration management system in Drupal 8 seems like a great idea, but what is it? In this session I hope to show what configuration management is, why it is needed and how it will make all of our lives as Drupal site builders better.

DIAPOSITIVAS SOBRE LOS VIRUS INFORMATICOSJulieethMC
En la siguiente presentación veremos los virus, tipos, características, antivirus, como solucionarlo, entre otros temas de gran importancia para nuestra actual tecnología.
Introducción a los virus informáticos y tipos de virus - Grupo 4odalisloor
Definición. Historia de los virus.
Precursores. Primer virus. Características.Clasificación. Causas. Módulos principales
de un virus informático. Métodos de
propagación
2. ¿Qué son los virus?
Es un malware que tiene por objeto alterar el normal
funcionamiento de la computadora, sin el permiso o el
conocimiento del usuario, habitualmente, reemplazan
archivos ejecutables por otros infectados con el código
de este. Los virus pueden destruir, de manera
intencionada, los datos almacenados en una
computadora, aunque también existen otros más
inofensivos, que solo se caracterizan por ser molestos.
3. Funcionamiento básico de un virus
Los virus se alojan en el interior de un
programa, normalmente conocido (pej MS Word).
Cuando el usuario abre este "programa” ejecuta
también el virus sin darse cuenta. En este momento
el virus pasa a la memoria RAM del ordenador y esto
le asegura seguir funcionando aun cuando se cierre
el programa.
4. Una vez alojado en la memoria RAM, estará
pendiente de infectar otros programas que se
ejecuten en el ordenador. La infección consiste
básicamente en copiarse a si mismo en otros
programas.
El virus lleva programado un trozo de código
conocido como payload, que es el responsable de
efectuar daños en el ordenador.
5.
6. Clasificación de los virus
Gusanos: Son programas que se reproducen a sí
mismos y no requieren de un programa o archivo
anfitrión. Porque se replica, este tipo de intruso puede
disminuir la capacidad de memoria principal o de un
disco; puede hacer más lento el procesamiento de
datos.
Bombas de tiempo: Son virus programados para
entrar en acción en un momento predeterminado, una
hora o fecha en particular. Se activan cuando se ejecuta
el programa que lo contiene.
7. Caballos de Troya: Son virus que requieren ser
copiados e instalados manualmente en la computadora
que será infectada, destruyéndola información que
esté en disco. Se introducen al sistema bajo una
apariencia totalmente diferente a la de su objetivo
final. Al cabo de algún tiempo se activan y muestran
sus verdaderas intenciones.
Virus de ocultamiento o Stealth (Fantasmas): Son
virus que tratan de camuflarse para evitar ser
detectados y eliminados.
8. Virus Polimórficos: Se cambia a sí mismo cada vez
que se propaga, por lo cual, al intentar identificarlo
buscando una secuencia de bytes que lo
caractericen, no se lo encuentra.
Retro Virus: Son los virus que atacan directamente al
antivirus que está en la computadora.
Virus Backdoors: Son programas que permiten
controlar remotamente la computadora infectada.
9. Virus Falsos o Hoax: Se trata de las cadenas de e-
mails que generalmente anuncian la amenaza de algún
virus “peligrosísimo” y que por temor, o con la
intención de prevenir a otros, se envían y re-envían
incesantemente.
10. Consecuencias de los virus
informáticos
Unirse a un programa instalado en el ordenador permitiendo su
propagación.
Mostrar en la pantalla mensajes o imágenes
humorísticas, generalmente molestas.
Ralentizar o bloquear el ordenador.
Destruir la información almacenada en el disco, en algunos casos
vital para el sistema, que impedirá el funcionamiento del equipo.
Reducir el espacio en el disco.
11. ¿Cómo sé si mi computadora está
infectada?
La PC funciona más lenta de lo normal
La PC deja de responder o se congela con frecuencia
La PC se bloquea y se reinicia cada tantos minutos
La PC se reinicia sola y luego no funciona normalmente
Las aplicaciones de la PC no funcionan correctamente
12. No se puede acceder a los discos o a las unidades de disco
No puede imprimir correctamente
Aparecen mensajes de error poco usuales
Los menús y los cuadros de diálogo se ven distorsionados
13. Como eliminar los virus y protegernos
de ellos
Tener instalado un antivirus en la pc.
Mantenerlo siempre actualizado.
Prestar atención a los mensajes que le advierten que ha
enviado un correo electrónico que contenía un virus.
Esto indica que el virus ha reconocido su dirección de
correo electrónico como remitente de correo
electrónico infectado
Puede continuar mejorando la seguridad de su
computadora y disminuir las posibilidades de que sufra
una infección mediante el uso de un firewall y
actualizando su computadora.
