DynDNS

Today I tried to set up a webserver at home that I can reach from the outside and I tried DynDNS which worked great to redirect an external static address to my dynamic ip. However there was a bit of trickery to get the HTTP requests through the firewalls to my computer. There are two routers before my machine but forwarding other ports have not been a problem, I have tried that before. But apparently HTTP was not just to enable it in the admin gui as the web admin interface itself ovverrode the port forwarding. However after searching some forums I found out which commands to use to disable that using the command line interface on the router itself and now everything works 🙂

When the sun dies… when will it get dark ?

Sometimes you hear that if the sun goes out it takes about 8 minutes until we notice it here on Earth as that is the time it takes for the light to reach us.

Sun

However this is not exactly true, it would be if the sun suddenly vanished or if the view was entirely blocked for some reason. But if you talk about the sun dying like a fire dies when there is nothing more to burn or like a light bulb dies out after you cut the power it will take much longer than 8 minutes for us to notice. So if suddenly the fusion process inside the sun stopped, how long would it take until there was no light ? Actually approximately a million years, and to a human that is quite a difference, so if the fusion stops I don’t think you should be very worried :-). However this was something that was mentioned in a radio program, it would be nice if could find a source on the net that mentioned this.

KDE 4 and SUSE

Because of a broken hard disk I recently reinstalled my os on my laptop. Lately I have mostly used Kubuntu, but as I have that already installed on several computers I decided try something else. As I was a SUSE user for some years I decided to install that again and see how it looked now. So I installed OpenSUSE 10.3, and it looked nice and Compiz worked fine even though it was a bit hard to find out how to actually enable it. Seems strange as this was one the new things with 10.3. However I prefer the package installation in Kubuntu as it’s faster. For some reason it seems to be much slower to start up compared adept or (apt-get update). Anyway the difference seems not big and everything on my laptop was found correctly by SUSE, I did not have to set up anything. So I am probably going to keep SUSE here and continue to use Kubuntu on my other computers, it’s nice to have something to compare.

As a summmary my linux usage and distribution history looks like this:

1998 I first tried Linux and I used Red Hat 5.1. Things were not as easy then and I remember I had to tweak a lot in the configuration files and look for hours on the net to try to solve simple problems, but I thought it was fun and in the long run you learned a lot.

Later in 2000 if I recall correctly I switched to SUSE and kept using it until around 2003 (versions 6.4 to 8.x), after that I used Fedora Core for about a year when I switched to Kubuntu 5.04. The versions and years might not be exactly what I just said, but approximately.

So next year I have used Linux for 10 years 🙂 , I have mostly used KDE as window manager but I have also used FVWM for some years.

Now there is work ongoing for KDE 4 and I tried KDE 4 Beta 4 on a SUSE Live CD today. But I was a bit dissapointed, I found bugs in almost everything I tried to do. It looks nice but right now it felt more like an alpha release than a beta.
