Como usar Sugar

Usando la Interfaz

¿Donde esta el escritorio?

Sugar es un entorno de escritorio distinto a lo que normalmente se utiliza en Windows, Apple OS X Linux u otros sistemas operativos. Lo primero que ve un niño, por lo tanto, no es un disco duro o una papelera, son otros niños en el "vecindario." Sugar usa la metafora de escritorio más cercano al significado de Home: donde el usuario puede ver las actividades que esta utilizando actualmente y accede a diario, actúa como un historial de uso y permite al usuario acceder a archivos que uso o aplicaciones que corrió anteriormente.

Usando las actividades

¿Qué es una actividad?

Los programas que se ejecutan usando Sugar se llaman Actividades. Porque? Porque Sugar, es un significado distinto para "escritorio" en una computadora, es el primer intento serio de crear una interfaz de usuario que se base en conocimientos y en socialización: los alumnos deben participar en la exploración y colaboración.

Empezando una actividad

Instalando y eliminando actividades

  • Instalando actividades usando el navegador
  • Instalando/eliminando actividades usando la terminal
  • Instalando/eliminando aplicaciones de Linux
  • Instalando el "revestimiento" Sugar para aplicaciones Linux
  • Aplicaciones de Windows

Personalizando la interfaz

Cambiando el nombre XO's y los colores del entorno de Sugar

    Tu nombre XO's y otras opciones pueden cambiarse desde la Terminal Activityo elSugar-Control-Panel.

Cambiando "Imagen de usuario XO"

Para cambiar la imagen de usuario XO, La imagen central del escritorio (con las aplicaciones solicitadas a su alrededor), tu debes seguir estos pasos:

  • Crear el icono Primero hay que hacer una imagen y guardarla como un SVG (Scalable Vector Graphics), con el nombre computer-xo.svg. Existen instrucciones sobre cómo hacerlo en el wiki de OLPC.
  • Transferir imagen a la computadora - Copia computer-xo.svg a una memoria USB o tarjeta SD y conéctalo a tu OLPC o computadora.
  • Instalarla - Abre una terminal y tipea los siguientes comandos para hacer una copia de seguridad el icono original y copia del nuevo icono en la ubicación correcta:
su -l
cp /usr/share/icons/sugar/scalable/device/computer-xo.svg /usr/share/icons/sugar/scalable/device/computer-xo.svg.bak
cp /media/<your usb or sd>/computer-xo.svg /usr/share/icons/sugar/scalable/device/computer-xo.svg
  • Ahora cierra la terminal y pulsa Ctrl+Alt+Suprimir.

Ejemplo de icono modificado:

 


Restablecer el icono original

Para restablecer computer-xo.svg y usar el original, abre una terminal y tipea: 

su -l
cp /usr/share/icons/sugar/scalable/device/computer-xo.svg.bak /usr/share/icons/sugar/scalable/device/computer-xo.svg
rm /usr/share/icons/sugar/scalable/device/computer-xo.svg.bak

Setting the Clock and Timezone

You may set the date and time as follows:

  1. Connect to the Internet. (For details, see Connecting to the Internet)
  2. Open a Linux prompt. (For details, see How do I access a Linux command prompt? Note that unless you are an advanced user, you should use the Terminal Activity button to open the prompt.)
  3. Log in as "root". Assuming you are using the Terminal Activity program, you can log in as root by typing "su -" at the command prompt and pressing the Enter key. Note that as user "root" you have the ability to destroy all software on the XO, so you should end your session as soon as you successfully change the date and time.
  4. At the command prompt, enter the following commands:
    /usr/sbin/ntpdate time.nist.gov
    /usr/sbin/hwclock --systohc
  5. Press the Enter key after each. In response to the ntpdate command, if it successfully contacts this US government official time server, the system will output a line of data displaying the correct date and time.
  6. Click the "Stop" icon 25px at the upper right corner of the screen to log out and close the Terminal Activity program.

How to set the timezone on my laptop

You can set the timezone by typing the Sugar-Control-Panel command in the Terminal Activity.

Sound Control

    Disabling the bootup sound

    Turn the volume down while the laptop is booting (i.e. before getting into Sugar).

Taking Screen Shots

To take a screen shot, typing Alt+1 at the same time will take one and store it in your journal.

Networking & Communications

Connecting to Wireless Networks

To some degree, networking is specific to the platform upon which Sugar is running.

    On the XO-1 laptop, there are three ways to connect to the Internet:
  • Wireless access point (WiFi hotspot);
  • “School Server” mesh network; or
  • “simple” mesh network, which lets you collaborate directly with other XOs.

Read Connecting to the Internet for detailed instructions.

Connecting to Jabber Servers

Jabber servers allow Sugar users to interact, play and collaborate with each other in the Sugar environment.

While the OLPC is designed with mesh wireless networking built in (where users can connect to each other without having a central wireless internet router/connection), Sugar users around the world may not be able to connect with others using the platform unless it's through the Internet, since mesh networking relies on a concentration of users (for example, in a classroom, school or business environment).

Jabber networks link Sugar users to each other in order to chat, interact and collaborate. There are global Sugar Jabber networks, or regional ones hosted by organizations and individuals around the world. You can choose whichever Jabber network you wish to connect to. Connecting Sugar to one of these networks will greatly enhance your Sugar experience.

IRC Chat

Install the XoIRC activity and connect with other Sugar/OLPC users and enthusiasts on the internet and chat with them in real time. XoIRC uses a system called IRC.

It defaults to a "room" called #olpc-help, but you can also enter other rooms by typing /join #room where room is the name of the room you wish to join.

Some other Sugar/OLPC IRC chatrooms are listed are listed here.]

OLPC/Sugar as Webserver

  • Open Terminal and type the following to install Boa (approx. 100k)
su -
yum -y install boa
  • Now put your index.html in /var/www
  • Find your Sugar Computer/XO's IP Address. Still as root user (having entered su- already), enter into Terminal:
ifconfig
  • Look next to eth0 for 192.168.whatever (for example)
  • Go to another machine on your LAN and type your Sugar Computer/XO's IP Address into your browser. There's your Sugar computer serving up a web page!
