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 between sexes regarding shower-count. Since we din't have a lot of time we had to cut down on what data we were to collect, we ended up with seven (expanded to eight during the [...]

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 my own network every 30 seconds and record the RTT min, avg and max. At the same time I recorded the inbound and outbound bandwidth usage. To visualize the problem I started with filtering [...]

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 appartment window as well as scraped another temperature measured about 10km away from from temperatur.nu. Since yr.nu updates their forecasts several times a day i wanted also wanted to [...]

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 two simple python scripts. One that would spew out SNMP packets as fast as possible and one that would listen on incoming replies and print out the content on STDOUT. The sending script created [...]
