A friend who works at Dreamhack asked me if I had any 24 led Neopixel-rings in my large store of good-to-have stuff. Unfortunately I didn’t, I could only find 12 led ones. In the crew area for the tech/network crew at Dreamhack in Jönköping they have had a display that show the number of active […]
A couple of years ago I saw that a store sold Kobo eInk readers relativly cheap and a quick google showed that it was possible to root them and do what you wanted, so I bought one, and rooted it. Unfortunately there were no ready made scripts or programs to display weather information on the […]
During the summers of 2013-2014 i played around with a raspberry pi and a 1-wire sensor placed near the beach Rocksjön in central Jönköping. Thanks to the kind people at Hasse på Sjökanten which is a Hotel and Resturant just by the beach I got to use their Wifi and power for the Raspberry Pi. […]
After having used the old dashboard a couple of events Telia contacted me if I could create a new one, and that I could. This time I got my friend from previous adventures on this blog, Mr Hannes. His master knowlege about design and UX combined with my backend expertese led us to a novel setup. […]
The Telia Dashboard for Dreamhack started to feel a bit dated so Hannes and I started thinking of doing a new dashboard, but in a different way. We brainstormed all the possible metrics at DH that we could visualize, everything from traffic in the network to how many cans of soda had been sold and the distribution […]
I did get the opportunity to play with data from the PacketLogic machines that was deployed at DreamHack summer 2011. Basically we parsed a log containing a subset of all connections, extracted the outside IP (independent from if it was source or destination) and ran that through MaxMinds GeoIP API to get lon/lat. The data […]
I was curious about statistics and network performance at DreamHack and wanted to get statistics for all of the user ports on the local network. There was no way a standard statefull program would be able to get the statistics for the hundreds of switches and thousands of ports on the network. So I created […]
While I lived in an apartment and was stuck with getting internet via some one DOCSIS5 connection over damp cottonthread I grew more and more irritated that I didn’t get the bandwidth i payed for. But, DATA > DOGMA, so created an experiment to collaborate my feelings. I started to ping the first router outside […]
After a discussion with a friend about how accurate yr.no was, compared to smhi.se, i set out to test it. DATA > DOGMA! I wrote a small perl-script that scraped the temperature predictions from yr.no and every hour and saved all the values. To have something to compare to I recorded the temperature outside my […]
