Adventures in (Dyn)DNS

By Johan Thelin | Published: 2020-07-31

So, I made the silly move to rely on my hardware supplier to provide me with a dynamic DNS service. Naturally, this offer expired, and I could no longer reach my home server. Because of Murphy, this naturally took place when I was away from home with no access to anything. So – how does […]

Photoframe Hack

By Johan Thelin | Published: 2020-05-26

Sometimes you just want to get something done. Something for yourself. You do not intend it to be reused, or even pretty. You build a tool. My tool was a photoframe with some basic overlays. I wanted the family calendar, some weather information (current temperature + forecast), time, and the next bus heading for the […]

The Cost of no Architecture

By Johan Thelin | Published: 2020-04-19

Like many others, I enjoy various reverse engineering and tear-down stories. Personally, I mean things like iFixit tear-downs and Ken Shirriff’s blog, so I started following this tweet thread by foone. I'm trying to get this Logitech Harmony 900 remote working, but it keeps telling me the battery level is extremely low… pic.twitter.com/v3CRE2BUD9 — foone […]

QML Weather

By Johan Thelin | Published: 2018-10-08

I recently took some time to develop a photo frame style home automation control panel. The idea is to control some common tasks of my home assistant setup from a panel instead of having to rely on the phone. To hide the panel, it currently act as a photo frame until touched. The build is […]

D-Link and the GPL

By Johan Thelin | Published: 2018-07-05

Recently my router died and to get netflix flowing again, I went out and got the cheapest router I could find in the vicinity. I ended up with a D-Link DIR-842 on discount for 499 SEK. In the box, I discovered this: It tells me to go to D-Link’s page for GPL licensed software to […]

Five days left

By Johan Thelin | Published: 2018-04-18

I use to joke that the last week before foss-north is the worst – everything is done, all that is left is the stress. This year, we have the broadest program yet. 25 speakers talking about everything from community policies, GPU isolation, blockchain, historical KDE software, retro computers, IoT, Android, SailfishOS, bug triaging, crowd funding, […]

Building Qt on Debian

By Johan Thelin | Published: 2017-08-21

I recently followed the advice of @sehurlburt to offer help to other developers. As I work with Qt and embedded Linux on a daily basis, I offered to help. (You should do the same!) As it is easy to run out of words on Twitter, so here comes a slightly more lengthy explanation on how […]

foss-north 2017 follow-up

By Johan Thelin | Published: 2017-05-08

On the morning of April 26 I arrived at our venue, preparing for around 120 people to fill the rooms at foss-north 2017. I’m still in the post-event cleaning up phase, so the visitor questionnaire has not yet been sent out, but the feeling is positive. This year we expanded changed venue and moved from one to […]
