A form with a join
A form is a document, or part of one, that can be used for the entry of data. A join is a construct in query languages such SQL. A join allows you to lookup data in one part of a database based on a query in an other part. Joins are very general, and may appear in other contexts. Such as the XML forms language.

A phone for elderly hackers?
The young and smart people people have smart phones. But what phone should an old hacker choose. My answer is Nokia N900. The only snag is that this gadget isn't really a phone.
Hardware, Reviews, 2010

A tale of two lenses
Here I discuss two lenses. Both are very new. I've owned them less than three months, and they represent recent developments from the respective companies building them. But appart from that they differ in almost all aspects. Even in the very idea behind their existence.

Bourne Again Shell
The Bourne Again Shell is a prominent part of my life. Dark moments I've felt that I'm obsoleted by modern technologies, but all of a sudden I realised that I'm as modern as smarphone users

Does hypertext promote extractive interaction rather than immersive?
Extractive and immersive are two forms of interactivity. This note claims that the digital library services have successfully implemented facilities for extractive media consumption but that it is very difficult to help users in the immersive pattern.

Drugs and OpenAccess
In a recent article Theresa Velden & Carl Lagoze (Communicating chemistry, Nature Chemistry 1, 673-678 (2009)) discusses how tradition and attitudes concerning IPR affect data sharing and how that in turn affects scientists propensities to use web 2.0 tools and web of data technologies.

Podcast: Mor minns
Min mor har tre år kvar till 100. Jag menar att hon är en helt fantastisk kvinna, med ett knivskarpt intellekt. Hon fick aldrig gå mer än sju år i skolan som barn, men i 60-årsåldern tog hon i princip gymnasiekompetens. I denna serie läser hon dikter och berättar ur minnet eftersom hon är nästan blind.

The proliferation of redundant meaning
I first used the term semantic drift about 10 years ago. It was a real danger then, it still is but the proliferation of synonymous vocabularies is worse still.

The syndication of style & layout
Quite a few and perhaps a majority of my readers seldom visits my site. This entry is about the problems of syndication and how you are limited by the styling and layout on the site where your material is presented.

Why you need a persistence strategy
Here I go through some of the arguments why you need to implement a persistence strategy. We also conclude that the hypertext link is the single thing that makes the Worldwide web to a web. Hence it is a serious thing. If you're working within the digital library world you should be devoted to the hypertext link.
Structural web design, Internet, 2010

My name is Sigfrid Lundberg. The stuff I publish here may, or may not, be of interest for anyone else.

On this site there is material on photography, music, literature and other stuff I enjoy in life. However, most of it is related to my profession as an Internet programmer and software developer within the area of digital libraries. I have been that at the Royal Danish Library, Copenhagen (Denmark) and, before that, Lund university library (Sweden).

The content here does not reflect the views of my employers. They are now all past employers, since I retired 1 May 2023.
