Why I am not on Facebook

Sunday, December 20th, 2009

Once in a while, one of my friends comes up with the dreaded question: why don’t you open a Facebook account? A reasonably simple question, followed by a rather complex explanation and stares of disbelief. Here, I’d like to address the issue once and for all if possible.

First and foremost, human relations are way more complicated than just a connection between two profiles on a social networking site and this is something we conveniently forget most of the time: family, neighbours, acquaintances, colleagues, friends and girlfriends are totally different groups, possibly overlapping and constantly changing, but each with a distinct set of information that you want to share and rules for doing so, informal as they may be. On Facebook, whatever you write in your status message and profile is visible by all your contacts regardless of their relation to you, with the obvious consequence that you have to write rather bland tidbits for the most distant group, i.e. neighbours and acquaintances, if you wish to play safe or risk exposing sensitive information if your target group is friends and colleagues. Not cool.

Sometimes my reply is that I already am an expert at wasting my time and don’t need another way of doing that. Though it is delivered with a smile, this answer has a deeper meaning: I already have LinkedIn for professional connections and CouchSurfing for traveling and meeting new people; keeping them up to date requires time and I have no wish for yet another social network site to maintain. I prefer to use that time for meeting actual people, as opposed to just reading their profiles, or for my hobbies.

Another underestimated issue is privacy, or lack of, in Facebook: without even getting into the conspiracy theories surrounding it, at least I’d like to try and keep my private data to myself, as much as possible. Usually, when I raise this point, the other party suggests that I create a profile with a pseudonym, which is naive for at least a couple of reasons: for starters if I were to use a service like this I’d want to use my real name to maximise its networking potential but, most importantly, we already know that anonymous data isn’t.

So, for the time being, no Facebook account for me. Thank you for your time.

Bluetooth tethering woes

Sunday, December 6th, 2009

As you might know, a pristine N900 supports tethering over USB only. To make it work over BT, you need to follow the instructions for adding a DUN server on Maemo.org’s wiki. Being always in a hurry, I never actually tried it until I came across Philip’s post on controlling Bluetooth DUN with upstart on the n900.

The good news? Using Upstart is the correct approach and obviously works perfectly as far as the data connection is concerned.

The bad news? Apparently, there’s some weird interaction going on with tethering and the phone data counter:  the traffic caused by the attached computer is not added to Settings->Phone->Data counter, which is simply overwritten. According to the dataplan monitor applet, before tethering I had used 24MB out of my monthly quota of 3GB but when the connection ended the counter was reading 2MB instead of 26MB. The reset date for the counter was unchanged, though, so I’m inclined to think this is not the intended result.

Bottom line: if you rely on the applet to monitor your quota usage and wish to use tethering, be aware that you need an alternate way to check your situation, such as 3 Wired Portal

EDIT: apparently the data counter is clobbered also when using DUN over USB
