Weather Station X-mas present

I've got a Weather Station WS-2036 from my wife as X-mas present. It can measure temperature, pressure, wind speed and direction, and rain. The best of all, it is possible to connect to a PC using the serial port. It is bought in the Swedish shop Jula and is working with Linux and Ubuntu.

Of course the package says nothing about Linux, Julas site says nothing, Heavy weathers site which the package refers to is equal bad. After some investigation I found out the the manufacture is actually La Crosse. All La Crosse weather stations WS-23XX should be compatible with the free software open2300.

Since I now have got my first moment alone since I got it I took the chance to test it. I reinstalled my lab-machine with Ubuntu 7.10 (Gutsy Gibbon). Installed the build-essential package. Downloaded Open2300 and compiled it, just write make. It worked out of the box. I think Open2300 will be a good candidate for me to provide through Ubuntu PPA.

Open2300 contains a kit of different small tools that reads data from the weather station. The most useful is fetch2300, xml2300. The first one reads data from the weather station and prints it to the screen. The other one writes an XML-file with the current data from the station. From here it will be quite easy to make my own presentation layer. There are also some php-scripts for presentation, which I have not looked into yet.

It seams to exist a lot of tools for presenting weather data and sites that collect those data. I will have to look in to those.

I must also mention that I got a cool BCD-clock from my wife's sister and boyfriend and a Photo frame from my sister and here family. I also got a bunch of nice cooking stuff etc, but since this is my tech-nerd blog I won't write more about them here.

I have got Ubuntu cola from my wife. I know that other Ubunteros have blogged about it earlier, but this is the first time I have noticed that it can be bought in Sweden. It is a Cola that is faretrade labeled which means that workers involved in the manufacturing are guaranteed to get paid a salary they can live on.

It taste like Jolt cola. It feels like it contains less sugar than Coca Cola. I wold not hesitate to drink it again.

I have committed a sin

Yesterday I committed a sin. I registered an account for Microsoft messenger. The reason is that some colleges using MSN and one of them will be home for child care after X-mas and work one day from home. So we needed a faster way to communicate.
I could not commit the sin without trouble so it looks like Microsoft and I agree with each other that our road must not be crossed unnecessarily. When I tried to install Microsofts own client it required that my client got upgraded. Since my computer at work is upgraded centrally I could not do that without installing Microsofts update client. If I do that I am on my own and my sysadmins will just wipe out my disk if I asks for help. The solution was to install Pidgin. The next problem was to register for a passport account, since I do not want a Hotmail account. It took a while to find the right place.

After an hour or so I was up and running. I must point out that I only use MSN for work, not for pleasure. The main reason I feel that using MS messenger is a sin is that the protocol is closed and not an open standard.

Our build continuous system support sending messages through Jabber/XMPP with results from the build. I hope I will get inspired to set up a Jabber server at work. My colleagues have promised to convert to jabber when I got it to work.

Can anyone recommend a good Jabber-server that is good, easy to install and runs on Linux?

X-mas tree in place

December has begin and it is time to X-mas decorate my office. So I brought my USB-connected X-mas tree to work and connected it to my Ubuntu desktop. The fiber optics has been glittering all day.
