RadiOS part 2


See RadiOS part 1.

So I started making a prototype to figure out if I could “sense” both selections with GPIO pins, while the designer started modeling and rendering suggestions for the physical design. The solution chosen was to first set all volume control pins to high, and check which channel control points registered as on, then reverse (control points high, check volumes).


Weather via finger, an update


I meant to write this post in Febuary, but never had the time.

Something exploded at Tuesday 2016-02-16.

I created the finger weather service in 2012, and announced it at Reddit. It got some mentions in Norwegian blogs, and i gathered a few regular users. See old stats in previous post.

I’m no fan of social media, and try to stay away. But apparently someone recently noticed the service and tweeted about it. Then blogs. Since I have regularly received “thank you” mails due to one of the random messages at the bottom (Mail a “thank you” to finger@falkp.no if you like the service.).


Using finger service the wrong way


If you’re doing this, you’re doing it wrong...

Your own Ruter.no realtime monitor


By request, a quick how-to on setting up your own realtime monitor for ruter.no, Oslos public transit.

Android with as little closed source as possible - part 2


Read part one of Android with as little closed source as possible, Life without US cloud services and Androids privacy invasiveness if you’re wondering why I’m doing this.

This is an update on how to live with a free and open (Android based) phone.


µg - A plugin-based replacement for gapps (updated)

This is a follow-up of Nogapps - A replacement for gapps.

The NOGAPPS project has been renamed to µg, and the part that interessts me the most, off-line, libre, coarse localization is called µg Unified Nlp.


graph.no - Weather forecast via finger

The idea

Yr.no has a brilliant hour by hour view. A simple picture where you get all info you need for planning your next 48 hours.


They also give out all their weather data for free! Having a special fascination for the command line, I wondered if I could represent the same information in a basic, ASCII, 80x22 terminal.


Google knows where you are by default

Even if you don’t use any Goolge services directly, Google will know a lot about you. For example when using the libre web browser Firefox from Mozilla. Let me quote from their site: “We’ve always designed Firefox to protect and respect your private information.”.

Geo location example

When using a location service, one get the message “Would you like to share your location with <website>?” when it should really say “Would you like to share your location with Google and <website>?”. This is stated if you “Learn more...”.

This may not supprise you, as Mozilla get 90 percent of its revenue from Google, and therefore use lots of Google services out of the box.

Mozilla started their own location service over a year ago with the goal to “Improve the privacy aspects of the geolocation service compared to the current market offerings.”, which is a good thing. It can be used by following this guide. My results has been varying.


Unfortunately Mozilla isn’t as open as they could be on this. They will not share their database. I recommend using OpenWLANMap instead, as they both are older than Mozilla Location Service and do share the database.

By installing this add-on you can transparently use OpenWLANMap in Firefox instead.

You can join in collecting data for both services by using Mozilla Stubmler app or OpenWLANMap app.

I’m not aware of any positioning for web browsers that works off-line, like one can on android using Nogapps.
