Welcome to diaforum.se

[This is Sandå,
the bridge over Sandåi, Rallarvegen, the old Bergen Railway track,
and Sandåvatnet at 1265 meters above sea level.]

This photo shows the bridge for Rallarvegen over Sandåi at Sandå, and the old Bergen Railway track towards Slirå. To the left of Rallarvegen is the beautiful lengthmen's house. A lengthman was a person employed to maintain a section of the railway. The house was built in 1913, and the architect was H. Kass. The lengthmen and their families lived here 1913–1969, now it is a private house.

To the right of Rallarvegen is the navvies' cottage at Sandå, where the navvies lived when the Bergen Railway was built in 1895–1909. A navvy was a person employed to build the railway.

Three well illustrated subjects are now up at this website

[Photo of larvae that chew on a leaf of a bird cherry tree.]

A larva is an active immature form of an insect. The larvae shown in my photos are coming from the eggs of the Bird-cherry Ermine moth — Yponomeuta evonymella — (Linnaeus, 1758). In Swedish this moth is named häggspinnmal.

About me and diaforum.se

My name is Conny Andersson and I am the manager of this website. I am a Swede. The photo below shows me as a two year old child in 1952.

What is the meaning of diaforum? Dia- is a prefix, and it comes from the Greek word dia. The meaning of dia is through something. The word forum comes from Latin, and the literal meaning is “what is out of doors, is an agora” — a public open space used for assemblies. The World Wide Web and the Internet are such public open spaces for assemblies.

This website's HTTP-server is located in Oslo

[Oslo and
Karl Johans gate on August 2, 2006.]

The Apache HTTP-server for this website is located in Norway, in Oslo near to the Akerselva river.

In Oslo you just have to pay a visit to The International Museum of Children's Art. See the world through the eyes of children!

About this website

As a rock solid platform for computing served the FreeBSD Operating System. That is a BSD (Berkeley Software Distribution - University of California, Berkeley) version of Unix.

The web pages at this website are written in the Extensible HyperText Markup Language 1.1 according to recommended W3C-standard. I wrote the text, and the XML-markup with an extended version of the classic Unix vi Editor, the superb VIM Editor (Vi IMproved). I have used Unicode for character references. That adds an other step toward the strictness of XML. As a matter of fact all of the web pages at diaforum.se are well-formed and valid XML documents, hence the XML icon.

The Extensible Markup Language, XML 1.0 was announced as a W3C (the World Wide Web Consortium) recommendation on February 10, 1998. The latest version of the XML 1.0 recommendation was announced on November 26, 2008.

XHTML 1.1 was announced as a W3C recommendation on May 31, 2001. CSS Level 2 was announced as a recommendation on May 12, 1998.

In XHTML 1.1 it is compulsory to make use of Cascading Style Sheets. The content and the presentation have been more separated from each other in XHTML 1.1, than in previous versions. XHTML 1.1 and CSS Level 2 are important steps into the world of XML. A world that would make genuine interoperability, and reliable exchange of information truly possible via computers. In XML there is no gap at all for faulty markup.

Restrictive proprietary data formats are not reliable to use for lasting documents, and secure exchange of information in computer networks.

Checkpoint W3C

Below you can run a parser to check for valid XHTML 1.1 at:

http://www.diaforum.se/ index.xhtml

And, check that: the Cascading Style Sheet is valid CSS Level 2.1
