Depression: I’m not cured and it can always come back

I’ve been free of symptoms of depression since September, at least until last week. I started to feel agitated, nervous, easily annoyed, sad, alone and unwanted. Over the weekend it became a bit worse. I don’t know the cause. It just came back. It also sneaks its way back into…

Working with a Pixel Slate

The day before Google introduced a bunch of new Pixel devices, I sold off the beloved Pixelbook I wrote about at the end of last year. I never regretted the purchase but I noticed that I wasn’t using it that much because I was working on my company issued Macbook…

Pixel Slate/Pixelbook features don’t work on G-Suite

Düsseldorf, seine Radfahrer und die RP-Online

Ein Freund wies mich heute auf einen Artikel über die Unvernunft der düsseldorfer Radfahrer in der Rheinischen Post hin. Das Solobild zeigt ausgerechnet den neuen Radweg auf der Friedrichstraße — zugeparkt, versteht sich. Arne Lieb beginnt seinen Artikel damit, wie ihm eine Frau auf einem Hollandrad aufgefallen ist, die ihren…

Customer mail support

In the past, I have been very vocal against automatic replies from ticket systems. I considered them to add no value while possibly causing the person requesting support some discontent. Let me explain why. Imagine you just sent a support request. Of course you’re hoping for a quick reply. But…
