===== Nokia N900 for an admin =====
Provides ssh and vnc. Nice features, gps, wlan, sip. My hints here are focused on getting the device to fill my admin-needs. I want to listen to the podcasts .  * pro: when buying this you actually get root without having to break in or something (hi iphone-slaves..)!
  * pro: has a keyboard
  * pro: contains complete linux-box, think of encrypted homedir, mobile notesbook with revisioncontrol, read ebooks (FBReader)
  * cons: heavier than android phones (but still lighter than my Nokia E90)
  * pro: many videoformats out of the box supported
  * pro: One of the things i really appreaciate is to use approaches well known from linuxworld to solve problems. Want the N900 act as wlan-station and NAT traffic to internet for other computers? Loading iptables-kernelmodules, activating routing, running dhcpd - all the known steps.


===== first things =====
  * terminal is part of the default installation, notes for usage:
    * how to get the pipe-sign: press the upper 2 of the left-most keys
    * you can get root on the device
  * datatransfers with linux:
    * bluetooth network works, ofcourse also usb-storage - but makes the files inaccessable for the n900 while shared
    * i use an ad-hoc network and mount the n900-filesystem via sshfs onto my linux-laptop - but not media-transfers like sounds
  * ipv6: 
    * for this you need to install a kernel with the required functions
    * after installation of that kernel the n900 grabs a ipv6-adress from my wlan where linux-radvd advertises my sixxs-subnet. The n900-browser did only ipv4-access for me, but the firefox from easydebian works fine with v6: dancing turtle on kame.net!
===== applications =====
  * many apps available, some already 'extras-repo' you just activated:
    * vncviewer, openssh server/client, nmap, mplayer, vim
  * emulators: bochs (x86 emu), scummvm, dosbox (run dos software), pearpc (there is a video showing mac osx 10.3 running on this), emus for maeme/c64, psx4all emulates playstation
  * amiga emulation:
  * 'Extra Decoders Support' provides additional codecs, there is even 'TeX Live 2009'
  * x11vnc: install it and access the n900-screen via 'vncviewer ip-of-n900:0' from a i.e. a linuxbox
  * mailing:
    * mails can be synced with google-mail or accessed via imap at google 
    * access mails from your own server via imaps
  * japanese input: https://code.google.com/p/scim-for-maemo/
  * games: activate extras-devel, 'apt-get install sense wormux freeciv-client-sdl prboom doom-wad-shareware', 'bounce 3d' from the nokia shop
  * even more apps: EasyDebian
    * install this to get a 4GB file-image, inside a complete debian with many more applications
    * openoffice/iceweasel are there by default, vpnc available for install.
    * dont forget to reboot the n900 after installation of the 4gb debian-image
  * browsers:
    * the internal browser is quite usable with the adblock plugin
    * opera10 runs on maemo
===== N900 for routing/NATing to the internet =====
  * **unsing wifi:** The idea is to have other devices/computers via wlan connect to the N900 and enabling them to access the internet (so NATing their connections).
    * the current wlan-driver has no code to work as AP-point, ADhoc should work thou
    * the default kernel is missing iptables-kernel modules, kernels providing this can be installed from repos

  * **using usb:** After connecting linux-computer and n900 via usb-cable select 'pc suite' as operationmode on the n900
    * Now i.e. on gnome the n900 can be configured and used as modem.
    * Here on debian loading of modules cdc_phonet and cdc_ether is triggered and 'dmesg' tells that device /dev/ttyACM0 is now available. Will use wvdial with it:
<code>
apt-get install wvdial
cat >/etc/wvdial.conf<<EOT
[Dialer Defaults]
Modem = /dev/ttyACM0
Phone = *99#
Username = t-mobile
Password = t-mobile
Dial Command = ATDT
Baud = 460800
Init1 = AT+COPS=0
Init2 = AT+CGDCONT=1,"ip","internet.t-mobile"
# Init2 = AT+CGDCONT=1,"ip","internet.t-mobile.de"
EOT
wvdial
</code>
  * **using bluetooth:** Havent used this yet.
===== snippets =====
  * accessing the cameras:
<code>
mplayer tv:// -tv device=/dev/video0 # back camera, 848*480 - 0.4 megapixel
mplayer tv:// -tv device=/dev/video1 # front camera, 640x480 - 0.3 megapixel
</code>

===== other OSs on N900 =====
  * https://wiki.maemo.org/User:Jebba/Fedora -- run Fedora12 on the N900
  * android runs, [[https://talk.maemo.org/showthread.php?t=49811|details]]
  * windows binaries:
    * one can run qemu (to emulate the x86 arch) and inside of it wine
    * also whole windows 3.11 runs on qemu
    * https://talk.maemo.org/showthread.php?p=664081 has a howto
  * megoo: This runs, at least the nongraphical core part. Megoo is currently developed on the n900 but will not be officially released and supported. There is not much reasoning for Nokia to do this as maemo is already a working system for the n900 hardware.
