Why I hate phone calls so much

The fact that I have more than 20 missed phone calls on my land line telephone after only half a day has passed triggers me to write this blog post.

It is simply impossible to get any productive work done if there are synchronous interruptions. If I'm doing any even remotely complex task such as analyzing code, designing electronics or whatever else, then the interruption of the flow of thoughts, and the context switch to whatever the phone call might be about is costing me an insurmountable amount of my productive efficiency. I doubt that I am the only one having that feeling / experience.

So why on earth does everybody think they are entitled to interrupt my work at any given point in time they desire? Why do they think whatever issue they have rectifies an immediate interruption in what I am doing? To me, an unscheduled phone call almost always feels like an insult. It is a severe intrusion into my work-flow, and has a very high cost to me in terms of loss of productivity.

Sure, there are exceptional absolute emergencies (like, a medical emergency of a family member). But just about anything else can be put in an e-mail, which I can respond to at a time of my choosing, i.e. at a time I am not deeply buried into some other task that requires expensive context switching and the associated loss of productivity. And yes, a response might be the same day, some days later, or even a week or more later. There are literally hundreds of mails of dozens of people that need to be responded to. I can never even remotely answer all of them in a timely manner, even if I'm working 12-14 hours a day up to 7 days a week.

Right now I'm doing the only reasonable thing that is left: Switch off all phones. And to anyone out there intending to contact me: Please think twice before calling me on the phone. Almost anything can be put in an e-mail. And if you really want to have a phone call, please request a scheduled phone call in an e-mail containing a very detailed agenda and explanation of the topic.

Strain of bad luck

From roughly September to December 2012 I seem to have had a quite unusual strain of bad luck and set-backs. I don't want to go into the details here, as most of the issues are of quite private nature.

This has kept me quite distracted from a lot of my other activity. Projects like the various Osmocom sub-projects, gpl-violations.org are in desperate need of attention, and I have severely neglected my responsibilities in the Chaos Computer Club Berlin e.V. :(

I don't even want to talk about actual paid work, where customers also had to put up with repeated schedule slips and lack of availability.

I let down friends and colleagues at a number of occasions, as I was unable to keep up with anything that remotely resembles my typical work schedule.

Last but not least, I regrettably have also not felt much of an urge to write many blog posts here.

My sincere hope and expectation is that things are going to improve quickly in 2013. At least most of issues from the last half year have been resolved. Now I need to work through a considerable back-log of work and find more time for my volunteer projects in the FOSS and hacker worlds. However, this will need some time and I would like to ask for some patience. I do intend to be up to speed with things just like before.

In this spirit, I am looking forward to a productive and exciting 2013. Happy hacking und Viel Spass am Gerät
