Internet access at Internetdagarna – broken

For the 12th year Internetdagarna is arranged in Stockholm. .SE is host of this wonderful event. It is really for me the peak of core Internet discussions in Sweden. Thanks .SE for all work!

But, Internet access does not work this time either. The problem I see is that .SE unfortunately did trust Stockholm Waterfront […]

Unethical content?

Långholmen blocks Patrik Fältström

I got a notification from a friend that when he tried to access my text about how Internet works, the page was blocked (as you can see on the screen dump he provided).

So it is inappropriate to read explanations on how this Internet thing works?

I do not think […]

Internet Access at UN meeting is limited

At the Internet Governance Forum MAG meeting today, I heard people start complaining they can not access their chat service, and then email, and then VPN server at home. I did not have any problems, but that was (as I now know) because my VPN came up.

I used the brilliant software Netalyzr, and found […]

Large amount of email, or?

When I a few minutes ago checked mail, I watched the progress bar, and was chocked. If the number was correct, some people on a mailing list would have sent some trillions of email messages in just 30 minutes or so. Impressive. I did not know my mail server could handle that.

When […]

UPS has problems with routing?

I have ordered some christmas presents for me and my family. Sent by UPS, and there where to be delivered today. But UPS managed to reroute the package wrong in Malmö. Interesting situation. I now ask myself whether I will get the package tomorrow. UPS routed my package wrongly […]

Broken email messages

I thought we knew how to format email messages. But no. A friend sent me this while smiling…

Optimization of web pages?

An article in Ny Teknik in Sweden discuss search engine optimization. Some good ideas, but of course the most important thing is that articles discuss the phenomena. Are the organisations that optimize the pages in combat with Google? Or are they only fighting each other? What I also would like Ny Teknik to look more closely at are other ways of optimizing. Optimizing the pages themselves. By for example looking at their own webpage. Just look at how many different domain names and servers the content is stored on. Each lookup in DNS takes time, and each new TCP connection for HTTP takes time. And what is worse, Ny Teknik can not themselves control the experience of the end user. Specifically when external sites are in such bad shape. Have a look at the diagram below and see how slow a specific server is from which Ny Teknik incorporate content. adserver.adtech.de is slowing down the Ny Teknik website considerably […]

Fastest path between GVA and CPH is not the shortest

Yesterday I left the IGF meeting a few minutes early to be able to pick up my bag and catch the bus to the airport. As all meetings end at the same time (18:00), I was worried the lines for bag pickup where long, so I left the meeting at 18:10 or so. Yes, the meeting run over a few minutes. There was no line, and I caught the bus to the airport. In retrospect, I could have staid a bit longer, but I could not know that. The lines when signing in Tuesday morning where so incredibly long. Took 40 minutes to get the badge. At the airport I bought some chocolate for neighbors (pssst…do not tell them, they do not know this yet), and walked through the security check. Inside the check there is a bar where one can get a sandwich and a beer, and I am happy I had some food. The flight was first (when I checked in) delayed 25 or 35 minutes depending on whether you asked SAS or GVA (interesting that they did not agree). Leaving 20:25 or 20:35. At the gate (A2 at GVA), we got the information boarding was delayed until 20:20. At 20:30 we boarded, still without changing the preliminary take off time. When boarding was completed, we got the news. The delay was not due to weather as they said at the airport. It was because of what I interpreted as strikes and conflict in France air traffic control, and technical problems with the German air traffic control. We where told we had a slot time out from GVA at 22:00. This would at this time imply about 1:05 in the airplane on ground. On top of this, the pilot said that for people to Gothenburg, they did not have to worry, as the pilots of our plane where the ones that would fly there… Everything was after all pretty ok. At first… At 21:40 we started taxiing, and we took off. Everything looked alright for about 30 minutes, until I really felt the path taken on the small monitors where not really directed towards CPH. I was really tired, and tried to sleep, but it was not easy as one wondered what happened. Towards CPH from GVA, via Prague? The pilot after about 40 minutes told us the story. We had not got a better slot time. Instead we where pushed to a slot time at 23:45. SAS then decided to ignore .DE completely and instead fly over airspace of .PL. This of course made the flight time 2:10 instead of the planned 1:25. On top of this, we had to try to ignore .FR due to the strike there. We passed Zurich, Munich, Prague and the western part of Poland. Then Swedish airspace until we arrived to CPH from the east. Of course landing at CPH was from the west. It seems to me that at CPH one always have to do a 180 degree turn before landing. Sigh. At last, we landed at 00:10 Friday morning. “Only” 2:10 delayed arrival on a flight that was scheduled to be 2:00. Not very good. Home at 01:35. Bed at 02:00. Tired… […]

Stockholm Farting Organisation?

In the newspaper friday, there was this picture with an unfortunate misspelling. The text claim that Anders Jansson is secretary in the Stockholm Farting Organisation (Stockholm Fisarförbund) while I am pretty sure he is secretary in the Stockholm Fishery Organisation (Stockholms Fiskarförbund).

Mondozer does not work on all phones

So I got this idea that I should try a new service. Ads made me a bit interested. But did it work? I got interested due to information from Eniro. Information on the Mondozer site was as interesting as what I saw on my cellphone (see below, they could not even do encoding of Swedish characters correctly). […]
