Gizmocall

Gizmocall is offering 10 minutes worth of free calls per day. It also works to mobile numbers, I have tested DNA in finland and a prepaid in france.

Calls can be made directly from the webpage, but you’ll have to install a small plugin to make it work. I had a memory owerflow problem the first time I tried it (it ate all my memomy and fille up the pagefile), but after restarting firefox it worked flawlessly.

I wasn’t able to test these free gizmocalls from my N800, because it’s still in service, but hopefully it works when I get it back.

Helsinki area routes and directions in Maemo Mapper

Update:
MaemoMapper now fully supports downloading of routes by address also in Finland. This makes the service of this post obsolete.

I’ve been fiddling with Maemo Mapper and Holux GPSlim 240 unit for a few weeks now, and I must say the combination is pretty amazing.

The problem I had was that though Route download works, and with flite I even get hilarious voice directions, there was no way of finding a route by a specific address. So I decided to do some bubblegum php with kartta.hel.fi and some coordinate transformation functions to make a service to get GPS coordinates from an address in the Helsinki area.

It’s not integrated to the Maemo Mapper, so you’ll have to copy the location to Route Download-dialog box, but It’s better than nothing. Feel free to use it.

Grsync without password using Public Key authentication

Update:Rsync is available for 770 here.

For N800 use this repo:

repo_name = mg
repo_deb = deb http://mg.pov.lt/770 mistral user other
package = rsync

Thins you’ll need:

First you have to gain root access. In Nokia N800 it works pretty much the same as in 770. I used the ssh-method explained in Maemo wiki.

Next you have to make the keys:

Nokia-N800-51:~/.ssh# dropbearkey -t rsa -f mykey
Will output 1024 bit rsa secret key to ‘mykey’
Generating key, this may take a while…
Public key portion is:
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABA…

Fingerprint: md5 e6:a6:45:84:9d:59:9f:4a:bf:97:12:ca:56:f0:36:60

Then edit the ~/.ssh/authorized_keys in your server to something like:

ssh-rsa AAAAB3NzaC1yc2EAAAADAQAB… username@myserver.com

Remeber to add the username@myserver.com to the end.

Then try to connect from your device to the server with the new key:

~/.ssh $ dbclient -i /user/.ssh/mykey username@myserver.com

If there is a problem with “random data”, the try this as a root in yourtablet:

mv /dev/random /dev/random-blocks
ln -s /dev/urandom /dev/random

Now to the Grsync configuration. In the source (or destination) field put: username@myserver.com:/directory and to the other field a folder in your tablet.

Next go to Advanced configuration tab end enter this to the other commands box:

-e “dbclient -i /home/user/.ssh/mykey”

Or with Open SSH (recommended)

-e “ssh -o PreferredAuthentications=publickey -i /home/user/.ssh/id_rsa_n800″

Now test your settings by pressing the icon representiang a lamp. If everything work okay, you can continue to the real stuff with the icon beside it. If you have known_hosts problems, go to the terminal and ssh you server with both use and root and save the key. Hopefully this helps your synchronization problems. I’m probably creating a crontab job for automating rsync. I’ll et back to you when I do that.

Links and other stuff:
Wee by now, everybody is confused, but here are the links for OpenSSH implementation:

Another blog up and running in the world

I have used my new Nokia N800 for a good week now, and decided to share my thoughts of it to the world.

This blog is about Mobile technology and services, mainly focusing on everything realted to Nokia N800 and the Maemo platform and development in general.

I’m currently developing software and services to the platform, and this is my way for getting into the community. Hopefully I’ll get something useful done in the following weeks or months…
