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.See also at the bottom of the page has useful links.
Burning Questions
- Collaboration: 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 to switch the screen between color to black and white
- How to copy and paste in the Terminal Activity?
Needs to be Investigated
- Find the preliminary manual (maybe in FAQ)
- See what the kids have done so far (Peru)
- document what you can do in the terminal (find, vi, screen capture - still need to copy and paste in terminal - copy to from vi, write, online apps, usb - how to switch to black and white mode vs color mode - how do you listen to an mp3 file downloaded from the web
Journal Activity
- This should be the focus for running the activities
- It is best to resume a journal entry to reduce the numbr of entries.
- Clean up is slow because you can only delete journal entries one at a time.
Questions/Problems
- What does the * mean in the journal? In gmail, a star can be selected as an object for an action
General
- USB drive
- document what you can do in the terminal (find, vi, screen capture - can terminal access usb drive - still need to copy and paste in terminal - copy to from vi, write, online apps, usb
- Specs http://wiki.laptop.org/go/Hardware_specification: - AMD Geode LX-700@0.8W (datasheet) 433 MHz - Disk (virtual on Flash) 1,048,576 KB (1 GB) from terminal df command - RAM from terminal tp command 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.
Questions
- how to switch to black and white mode vs color mode - how do you listen to an mp3 file downloaded from the web
Terminal Activity
- how to copy and understand the journal better
- man pages arenot loded so I went to http://www.linuxmanpages.com
- Terminal can access usb drive. It is mounted on /media. df shows the mount.
Questions
Write Activity
- insert image only goes to journal with poor choices - search is in edit, it is good but it should behooked upto ctrl-fffff - to work on two files, open in two activities and transfer data using the clipboard on the left? http://wiki.laptop.org/go/New_Users#Opening_files clipboard is not pieces of text but launche the application, but ctrl-c and ctrl-v work - has spell check, but no auto find; how do you add a word maybe /usr/share/dict/words (no, this is empty) - has an auto page break - write can save (keep) as html and rtf
Browse Activity
- FullScren: alt-enter toggles
- View Source: cyrl-U does a view source for web pages but is really slow
Questions/Problems
- How do you tell what web site you are on, or going to (no status bar)
- Adobe Flash does not seem to work, for example, pandora.com flash message pops up, then nothing
- Cannot search in browse
Spreadsheet
- This killer app is not ready yet. It is listd on the download page as in development=
- Google online spreadsheet can be used
Brainstorming
- Find python spreadsheet and install it
- Make your own activity, maybe a unix command (for example, find) but tie it to an actiity
- Write tetris and install
- Talk to Ken Gamble about online comunity and physical community.
- Voice recognition and intruder alert
- Picture or video processing using the camera (intruder alert)
- Speech recognition (voice list application)
- Use a lot of online apps
- Screen capture: it looks like you get a screen capture called screenshot when you copy something to the clipboard. It is stored in /home/olpc/.sugar/data which you can get to from the journal
- Install linux and sugar on another PC so we can work with it without the laptop. Emulating_the_XO
- See what the kids have done so far, for example, Peru.
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.
Keyboard=
- top row: esc search(journal) neighborhood friends home activity - laptop.org getting started keyboard - what are the other panels next to the touch pad - what is the hand key next to alt: it is shown on the web getting started, as not used yet - alt-enter toggles full screen mode which can be used in write, browse - fn-erase erases from the right - alt-f is the same as frame button on the upper right this works in write but not in main view - alt-n goes to journal - alt tab cycles through the activities - alt-p cycles through the activities - alt-r rotates the screen - can you hang the keyboard mapping or add new key shortcuts?
Problems
- Sometimes the touchpad goes haywire; reboot fixes; maybe a memory management problem
- Wireless does not support wpa encryption. wep works. I used shared key with HEX. I needed a reboot to make it work.
Not so burning questions
