A Simple WiFi-Scanner for Linux

linux wifi python The current issue of the c't magazine features articles about improving the wifi signal at home. They cover a Windows tool called inSSIDer, which shows the wifi singal levels on the channels 0-13.

However, there's no such tool for linux. I came up with a simple solution in python, which parses the output of iwlist scan. This file is tested on Ubuntu 11.04, this one runs on Ubuntu 11.10. Both scripts can be executed like this: watch 'sudo iwlist scan | python wifi-graph-*.py' This is a quick hack, but it works great for me. Feel free to improve the scripts!

AGTL for Meego/Harmattan/N9: Beta 1

n9 meego agtl linux maemo AGTL brings offline geocaching to the N9, and I today present the first beta version. This means, in the next time I'll try to fix bug, but not add any new features.

This beta version brings

• Multicache Calculation help - AGTL tries to extract calculations from the cache description and you'll be asked to enter the missing values.
• Much improved interface and a dark theme (optional). On the OLED-Display of the N9, this saves power and it's a great for night geocaching.
• Favorite Geocaches
• Image view
• Website parser update - AGTL searches for an updated website parser when you launch it.
• and several other features.

What's left to do? When this version has become stable (i.e. when it has no major bugs left), I'll add

• Offline Maps
• Attributes
• Augmented Reality View (I disabled this in the current version due to some bugs)
• Handling of archived caches (Currently the "archived" status of a geocache is not shown anywhere)

Download the beta version here or wait until it appears in the Ovi store. If you downloaded it to the N9, click on the file and follow the instructions. Otherwise, enable developer mode. Run devel-su in the terminal to become root, then run dpkg -i /home/user/MyDocs/Downloads/agtl-beta-1.deb (change the path accordingly).

Please report bugs to github and only to github (otherwise I may lose track of the bugs). Please try to provide an output log of the program run. You can start AGTL by running agtl-meego in the terminal. If you run agtl-meego > errorlog.txt 2>&1 it will create a file errorlog.txt containing valuable information for bug hunting.

As always, donations are very welcome. AGTL will stay free (as in beer) also when it hits the Ovi store. Maybe I'll add a donate version to the store (with exactly the same features/support as the free version).

AGTL for Meego/Harmattan/N9: Alpha 2

n9 meego agtl linux maemo It's finally here! AGTL brings offline geocaching to the N9. Well, not completely: The map is not stored offline right now, but this feature will arrive eventually. This is an Alpha version, meaning there will be bugs. However, I already went geocaching with it and it worked!

AGTL features several cool features:

• Compass view
• Map view
• All details and images, the last 20 logs
• Writing fieldnotes
• Of course, some settings
• And best of it all: A unique augmented reality view!

Download the alpha here. If you downloaded it on the N9, click on the file and follow the instructions. Otherwise, enable developer mode. Run devel-su in the terminal to become root, then run dpkg -i /home/user/MyDocs/Downloads/agtl-alpha.deb (change the path accordingly).

Please report bugs to github and only to github. Please try to provide an output log of the program run. You can start AGTL by running agtl-meego in the terminal. If you run agtl-meego > errorlog.txt 2>&1 it will create a file errorlog.txt containing valuable information for bug hunting.

Please consider a donation if you like AGTL. It will stay free (as in beer) also when it hits the OVI store, although rewriting the UI for Meego took a lot of hours in the last weeks.

First Screenshots of AGTL on the N9

agtl linux qml The new user interface for AGTL, completely rewritten using QML, makes progress. Here are some screenshots. Your feedback is very welcome, but please keep in mind that things are far from being finished yet! The magnetic compass in the N9 seems to be pretty good, promising a much better geocaching experience!

Announcing the Nokia N9 Qt UI

agtl linux meego n9 Hi all! I was pretty busy in the last weeks, therefore only some minor changes to AGTL were made. However, last week my N900 broke (the famous USB port problem). Yesterday I decided to buy a N9 as replacement. Therefore, I'm preparing a Qt release of AGTL which will run on the N9. I expect a first public version in a few weeks. If you are the owner of a N900, don't be alarmed - development also continues for this device.

You can read more about the progress on the github repository.

The N9 was quite expensive, so I appreciate your donations for the development of AGTL on Maemo and MeeGo even more.
