A metal detector is very nice, particularly when there isn’t a lot of aluminium in the ground. Archaeology cannot do without it. But what I really want now is a holographic radar instrument. Still in the prototype stage, this technology is being developed by Tim Bechtel of Franklin & Marshall College in Lancaster, Pennsylvania and…

Using the @johndoe method to communicate over Twitter is a really stupid way to use the medium. Aren”t people aware that all their followers receive those tweets just as if they were normal ones? And aren’t they aware that many of their followers will thus receive only half of a usually pretty pointless chat conversation?…

Swype: Fast Text Input for Android

For me, the main drawback of switching to an Android phone was not having a physical keyboard any more. Typing on the touch screen keyboard is infuriatingly slow and error-prone, even if you use the word-suggestion feature. (It isn’t very smart, offering word suggestions not in order of how frequent each word is in everyday…

Swedish Heritage in Your Smartphone

The National Heritage Board of Sweden has released a beta version of a location-aware heritage-data browser for Android. The name is Kringla Mobil, and it talks to the central mash-up database that collates information from museums and organisations all over the country. My Visby buddies Lars and Johan are driving forces in the project. I…

Facebook Fail

Facebook has turned up security a notch and effectively locked me out when I’m on the road. I have hundreds of Fb contacts that I don’t actually know and wouldn’t recognise if I met them in the street. Mention their names to me and they ring no bell. This is partly because of this blog,…

Trainblogging

It’s been more than four years since the first time I blogged about how cool it is to have broadband on a train. But I still haven’t gotten over it. Trainblogging again! The sun is shining and Södermanland zips past outside the window. I’m on my way to Linköping to drop off finds at the…

Tech Note: Android Smartphone

I recently switched from a 2008 smartphone running Windows Mobile to a Samsung i5700 Galaxy Spica that runs the open-source operating system Android put out by Google. Here are some impressions after two weeks of use. I really miss the old phone’s hardware keyboard. Typing on the touch screen is slow and error-prone, especially since…

Like Swedish Mail, many mail services worldwide, I believe, offer a service where you e-mail them a letter and a list of addresses and they do the paper mailing for you. But now Finnish Mail is trying something pretty badass: they’re doing it the other way around to cut costs and CO2 emissions. Instead of…

I Axed My Heat Pump and Now It Works Again

There was a lot more ice in the heat-pump box than I had thought, a 10 cm cake covering its floor, but getting rid of it proved easy. All I needed was a screwdriver and a small axe. The hot air gun wasn’t much use. I turned off the power feed, took the hood off…

Ice Buildup Under Heat Pump

This morning when I got my bike out of the yard to take Juniorette to school, I heard a loud clattering noise from the box-like outdoor part of our air source heat pump. At first I thought the ball bearing on the rotor had crapped out. But the guy who installed it explained over the…
