User:Dulcan/Alvin hints and questions

This page is a running review of what I found out on the XO laptop beginning December 21, 2007. I purchased the laptop with 20 friends at work in the 2 for 1 deal. The information was obtained through trying it out and various help pages on http://laptop.org and http://wiki.laptop.org. Feel free to contribute to help us laearn more about using the laptop. This document was started with vi in the Terminal Activity and copied to the Write Activity using the Browser Activity to see the file system. It was, in turn, copied to this page. Liberal use was made of ctrl-a to select all, ctrl-c to copy, and ctrl-v to paste. All of the editing was performed with the XO laptop.

Burning Questions

• How do I gt together with other laptop owners in Fremont, Palo Alto, or Mountain View, California? I expect a lot of people from Google bought it, so I can probably go there.
• How do I copy and paste in the Terminal Activity?

   maybe /usr/share/dict/words (no, this is empty)

     Mem:    237844k total,   226552k used,    11292k free,        0k buffers
   - the ram and virtual disk are in file:///home/olpc/alvin/memory
   - Camera. speaker, microphone, speaker/microphone jacks
     3 USB ports, SD  memory slot
   - since this memory is all flash, how does it know between original and
   new files.

- exchange data with the outside:

 - terminal: USB drive is mounted on /media
 - journal automatically shows the drive at the bottom of the screen:
   - USB files can be opened from the drvie 
   - drag a journal entry to the USB icon to copy to USB.  

- browse to laptop.org/start

 - how to print: docs say you cannot print at this time
 - how to change dates especially time zone( terminal date)
 - how to get version (build 650, for example mentioned on the browse
   wiki page)
 - volume control: I saw it in a music app; buttons on keyboard
 - it would be nice to view all of the activities on one screen rather than
   having to scroll through the icons at the bottom o the screen
 - clipboard is on the left side of the home view

 - alt-r rotates the screen
 - can you hang the keyboard mapping or add new key shortcuts?

   management problem
