Wishing you all a cozy season with lots of nice jazz music and a colorful fall! Enjoy this video with the young and amazing jazz musician Grace Kelly. Most of all, she is one of the greatest jazz saxophonists in the world, despite she is just 27 years old. In this video she performs with Julian Pollack on piano, Julia Adamy on electric bass guitar and Ross Pederson on drums.

Grace Kelly is also a singer, composer, songwriter and an educator in jazz music and improvisation. You can read more about her approach to music education in JAZZed ‒ The Jazz Educator's Magazine:
“Grace Kelly is reinventing the rules of jazz and jazz education one step at a time. A musical wunderkind who began learning classical piano at six and quickly transitioned into jazz piano, then saxophone by age 10, she was always meant to turn the music world on its ear. The alto sax player performed publicly for the first time at age 10 (you can find the performance on YouTube), then, at the behest of her music teacher Ken Berman, recorded her debut album Dreaming at age 12. It's been a wild ride ever since for the 27-year-old bandleader, singer, and songwriter.”


“The Three Musketeers” – Audun Lindhjem, Svanhild Lindhjem and Johs Steine – rode Rallarvegen, the navvies' road, in Norway on August 20, 2016. They rode by bicycle the 55 kilometers (34.2 miles) from Finse to Flåm. It is the same route I myself rode by bicycle on August 1, 2002 and also partially on August 1, 2006. Both in 2002 and in 2006 I rented my bicycle at the Finse 1222 Rallarvegen bicycle rental, they also offer Rallarvegen packages with overnight stays at the Finse 1222 hotel.

Rallarvegen is the old navvies' road used by the navvies when they built the mountainous section of the Bergen Railway line in Norway. A navvy was a person employed to build the railway.

The navvies' road – Rallarvegen – was built in 1895–1902 (Rallarvegen's history in Norwegian) and the Bergen Railway line was officially opened on November 27, 1909. Please enjoy this amazing bike ride and video!


Four well illustrated subjects are now up at this website

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.

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.

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.

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 first 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 and last modified on February 7, 2013.

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.

This website is now ready to operate via the Internet Protocol version 6. IPv6 was standardized (RFC 8200) on July 14, 2017.

At the Internet Society I found a very strict tool to check if IPv6 is correctly configured: the nat64check. First it does a NAT64 check to see if it is correctly applied. It checks the Path MTU Discovery (PMTUD). At last it checks if the IPv6 works correctly as a stand-alone Internet Protocol (IPv6-only) at the actual website.

You may see diaforum.se's full-blown IPv6 readiness at nat64check.
(Vimeo's video player is not fully IPv6 ready, hence I use my Rallarvegen website as an IPv6 readiness reference.)



Checkpoint W3C

[W3C tools for quality.]

Due to the Vimeo videos at the start of this web page I have to fall back to XHTML 1.0. The iframe tag is not allowed in XHTML 1.1 and the allowed object tag does not work in some browsers. And, you can't see the Vimeo videos in fullscreen at this website because the Vimeo code (the API) for that breaks the rules for well formed XML and valid XHTML.

Below you can run a parser to check for valid XHTML 1.0 at:
