A month of MSI S271 with Ubuntu Linux

I have now had my laptop for a month. The laptop is great in size, weight, and speed. Most hardware components I have tried works. So I am happy.

Okey, but what is not working? I have noted three things.

First, the earphone connector does not work. According to some info on the net there are a patch for Alsa that should make it work. Maybe it will work in Feisty. I have not been digging deeper into this, my need have not yet been that big.

The second thing is when you want to have dual head. I have had dual head running for years on Matrix and Nvidia cards on my desktop. But I do not get the ATI card to handle two screens with different resolution. It works fine if I have the same resolution, I can switch back and forth between only laptop and dual head. There are newer releases of the ATI-drivers on ATI's web site, but I have not tested these. I have until now only tested the drivers in Edgys multivers. I am using the closed source drivers since I want to use the hardware acceleration.

Third, I do not know how to turn of the tapping function on the touch pad. I thought I would get use to it, but I am not. It is time to look into that.

Until now I have not tested:
  • SD/MMC/MS card reader
  • Bluetooth
  • Microphone

Circles in PostGIS

Image
OGC and PostGIS has no data type to represent a circle. Instead one use ST_Buffer(geom, distance) to get a geometry that covers the area within the distance to geom . So if geom is a point you get a circle. But it does not return an exact circle. The circle is approximated represented by a polygon using eight points. One can increase the precission by adding a third argument to ST_buffer that is the number of points in the polygon returned. The unit for distance depends on what SRID is used. But what if you have a geometry that you know is a circle created with the method above? There is no exact method as far as I know, but her comes a good approximation. First we want the origo of the circle. ST_Centroid(geom) comes to handy. It returns the centeroid point of the geometry, in this case the origo of the circle. To get the radius we pick out the first point in the polygon returned by ST_Buffer with PointN(ExteriorRing(geom),1) . We need to call ExteriorRing to get the polygon of

Create your own CA with TinyCA2 (part 1)

Image
A Certificate Authorities (CA) issues certificates to people and organization that gives us the possibility to know that we surf to the right web site and not a phising site. This concept can be nice to use on your private sites too, but you may not want to spend a lot of money to get a certificate for your site. Most common when one installs a web-mail server at home is using a self signed certificate. When one surf to the web-mail server from a friends computer one can not be sure that nobody listens to the traffic if one not verifies the signature of the self signed certificate. Maybe an easier and definitely a more scalable solution to this is to create ones own CA structure. When we are ready with this how to you will have installed a certificate on your web server, installed the root certificate into your Firefox, and you will have the root certificate stored on a USB-memory stick. First time you want to read your mail from a friends computer you install the root certificate f

Create your own CA with TinyCA2 (part 2)

Image
In part one of this series we created a root CA, a sub-CA and a certificate for our web site All certificates are stored in TinyCA2 s configuration. In this part we will: export the root CA:s certificate import the root CA:s certificate into Firefox export the certificate for the web site configure our web server to use the web site certificate To be able to import the root CA certificate to Firefox we must export it from TinyCA2. In the main window of TinyCA2, open the CA-menu and select Open CA. Select your root CA. Select Export CA Certificate in the toolbar, which is the second icon from the right. You may change the file name. Press Save when ready. Start Firefox, select the Edit-menu and Preferences. Click the Advanced icon and then the Encryption tab. Select View certificates and then the Authorities tab. You can see all the CA:s you trust. Click Import and select the file with your exported root certificate. You can in the Downloading Certificate window control what purpo
