Martin Bril heeft zich niet helemaal aan mijn voorspelling van gisteren gehouden. Vandaag schrijft hij over de kans op rokjesdag vandaag. Misschien moet Martin Bril eens de Uithof in Utrecht bezoeken waar het volgens mij toch echt al gisteren rokjesdag was.

Het is vandaag rokjesdag 2008. Ik voorspel dat morgen bijna alle krantencolumnisten die zich dat kunnen veroorloven dit gaan opschrijven. Vooral Martin Bril zal dit nieuws niet onvermeld laten.
Dat u het even weet.

Today is one of those if you don't like the weather, wait five minutes days. I have seen snow, hail and sun in the last thirty minutes and rain will probably happen too soon. The webcam shows interesting cloud views and the temperatures at home are dropping due to the snow on the roof.

A few updates to the weather maps recently: The maps are now generated each hour and there is a list of the recent weather maps.

My first CPAN upload. I uploaded Geo::METAR 1.15 to CPAN just now. Time to find out if I did stuff right.

Some environment sensors at home are now public. Started with the environment sensors of the home server gosper which are the easiest. Other stuff will be added if and when certain monitoring projects go from being a wild idea to delivering real data. Ok, I did order some temperature sensors and a 1-wire controller from Hobby Boards 1-wire solutions.

Major bad weather in Oklahoma at the moment. Some pictures and videos at TornadoVideos, normally for other extreme weather happening in Oklahoma. Link via Randal Bradakis.

Updates to the logic behind the weather maps at http://weather.idefix.net/ and updates to the stations list. Data is now fetched from multiple sources and with a lot of searching I found the locations of a number of stations such as EHFS (Vlissingen), EHSC (Lichteiland Goeree) and EHKV (oilplatform K14-FA-1C). Starting tomorrow morning the updates will be visible in the generated maps.

The weather keeps me interested and I have been working on processing weather data (ofcourse using Geo::METAR). Roger Burton West did a lot of work on visualizing weather data and I updated the result for Geo::METAR. Resulting maps now available on http://weather.idefix.net/. Stuff to add: caching, getting data from several sources (at least one metar for the Netherlands isn't available via the US national weather service) or using different sources.

Een simpele vraag waarom doe je niet het weerbericht? toen ik me afvroeg wat ik nog meer kon doen in Asterisk heb ik nu beantwoord met Asterisk metar weerbericht. Nu nog in het engels, omdat de weertermen in het engels zijn en omdat nederlands voor festival nog erg in ontwikkeling is.

Sometimes you run into a very oooh, shiny! subject when looking for something else. I visited David Taylor's pages looking for his writeup of FreeBSD NTP server with an external GPS mainly to 'compare notes' with my own FreeBSD ntpd PPS setup (PPS slave) writeup. No surprises there, but one click led to the other, when I found out that David Taylor is also interested in receiving weather information and dove into that. He has a nice overview of his experiments in weather satellite receiving and decoding and I found out about EUMETCast data where you can receive weather satellite images via a satellite dish. Which uses a 'data' PID on a transponder, which is implemented as multicast data streams. Several personal interests for me and work-related stuff comes together in this. It's good to know this exists, but I won't be running out to buy a satellite weather map receiver now.

Wardriving results 23 - 26 May: 648 new networks with GPS. I planned to go for a really big run through Nieuwegein last Friday, but a bit of rain as soon as I left turned into soaking rain within 20 minutes so I returned home.

Wardriving results 1-5 March.. quite boring because I used the car a few days because it was snowing (four wheels have less problems with snow). 71 new networks with GPS, 1549 seen in total.

Interesting webcam stuff (this subject keeps interesting me!).. the Alaska Volcano Observatory has webcams monitoring several active volcanoes in Alaska. The people in the areas affected by these volcanoes visit the site often to get warnings of possible ashfall. Great site, and it is good to see how modern communication methods (radio networks, internet, web) improve the flow of specialized news to faraway communities interested in that specialized news.

It is raining, and it will rain for the next few days. Forecastfox is showing it. So I get lazy and take the car to work.

An explanation for the white stuff outside. It is snow.
