Restart WWW

Published: 2009-04-13 16:31 UTC. Tags: world wide web

I'm on a bus4you with destination Oslo for a visit to Opera Software's main offices. The bus has wireless internet. That's good, I've been reading webpages on map-reduce, distributed filesystems and other interesting stuff the whole trip.

The bus driver mentioned that the network sometimes stops working, and requires a restart when that happens. It happened, and after confirming with one of my co-passenges that they too had trouble, I went to tell the driver.

No problem, he said, I'll restart it. And to restart it, he pressed a button marked "WWW".

So, if the WWW doesn't work for you, now you know where to find the button with which it can be restarted - just find the nearest bus4you bus! :-)

efod.se - now via IPv6

Published: 2008-11-29 19:19 UTC. Tags: world wide web network ipv6

I have been intrigued by IPv6 for a long time. The worldwide challenge of smoothly switching from IPv4 to IPv6 without end-users noting the switch is fascinating.

Getting IPv6 adresses for clients or servers where the IPv4 network provider doesn't provide IPv6 natively is very easy - there are several tunnel brokers. I have two tunnels at SixXS - one to get IPv6 at home, and one to get IPv6 to my Slicehost machine (the one serving you this blog post). DNS AAAA entries have been added, so with IPv6 support on your client, you can now reach efod.se via IPv6.

However, IPv4 is still required for access, because the slicehost DNS servers that I'm using are reachable via IPv4 only.

To ensure a high nerd factor of efod.se, I have also modified django to add a footer to the end of all pages with a happy message if you're running IPv6 :-).

Some people take their anti-spam measures very seriously..

The municipality of Linköping distributes a magazine, DIALOG, to all its citizens four times a year. The articles are about subjects like the new fire station, upcoming big events in the city, etc.

There's always a minor section with information on how I can contact my local politicans. There's a list with the name, a photo, a phone number, and an e-mail address.

To my surprise, the e-mail addresses were on the form givenname.surname&linkoping.se - that is, they had replaced the @ sign with an & sign. In a publication printed on paper!

There's even an explanation at the end of the page "because of a decision in the municipal council, @ has been replaced by &".

One has to wonder what they are afraid of - that someone will scan the paper, run it through OCR, and place the result somewhere on the internet?

Of course, the real reason is either that the municipal council made a very bad decision because they don't know that they are doing, or that someone has misinterpreted the decision. Either way, the result is a usability disaster - not all people know how to properly format an e-mail address.

URl as UI - a bad example from the real world

Published: 2007-09-16 14:04 UTC. Tags: software world wide web

In todays issue of Dagens Nyheter, the largest morning paper in Sweden, an article about pensions caught my eye, not so much because of the subject, but because of the URLs they referred to in the article. Here are the three URLs they referred to:

The first one is OK from a user interface perspective, but the second and the third one made me chuckle, especially as the second one actually had a note which freely translated went something like "Note that four underline characters are needed for the direct link to work".

Clearly, the people who designed this web site have not read neither Jakob Nielsen's "URL as UI" nor W3C's "Cool URIs don't change". I guess they never thought about being referred to from a newspaper in print where people actually have to type their URLs into their web browser.

Dagens Nyheter tries to make the situation better by providing a link to their online version of the article at dn.se/pensionskryss, which indeed makes it a bit easier for the readers to click the links. Sadly, the webmasters of Dagens Nyheter haven't done their homework either - the link is just a redirect to the article, which has this beautful URL: http://www.dn.se/DNet/jsp/polopoly.jsp?d=547&a=692119. So, let's say that you saved a bookmark to the article, and want to refer a friend of yours by word of mouth a week later when you have forgotten that there was a human-friendly link available - now you must send the link via e-mail or other electronic media. Simply telling your friend over the phone is completely impossible, which it would not have been if the link were something like http://www.dn.se/ekonomi/2007/09/16/pension.

Oh well.. the world is far from perfect. Happily, at work, we're using a content management system that automatically creates URLs that look nice: Plone.
