About this blog…

I am employed by Netnod as head of engineering, research and development and am among other things chair of the Security and Stability Advisory Committee at ICANN. You can find CV and photos of me at this page.

As I wear so many hats, I find it being necessary to somewhere express my personal view on things. This is the location where that happens. Postings on this blog, or at Facebook, Twitter etc, falls under this policy.

The views expressed on this post are mine and do not necessarily reflect the views of Netnod or any other of the organisations I have connections to.

Ett flertal incidenter under senare år visar att cybersäkerhet är ett område där kunskaperna behöver höjas bland svenska företag och myndigheter.

Digitalisation and the Internet

In Sweden, as well as in many other countries, digitalisation is in full swing. Since the end of the 19th century, Sweden has been working to make society more efficient with the help of technology and that friendliness to technology still exists. As a very sparsely populated country we have special needs, but also enormous […]

Digitalisering, Internet, Digitaliseringsrådet och ännu mer…

I Sverige liksom i många andra länder pågår digitaliseringen för fullt. Sverige har sedan industrialiseringens dagar i slutet av 1800-talet arbetat för att effektivisera samhället med hjälp av teknologi och det är ingen skillnad nu. Det glest befolkade landet som vi har ställer krav, men ger också enorma möjligheter till förändring. För att öka landets […]

Trademark Clearing House and Internationalized Domain Names

The other day I discussed TMCH and IDN’s with a few people from ICANN Staff. They where very very patient and that gave me the ability to think really hard trying to understand what the issues I feel really are. At the end I think we have the embryo of a problem statement. A statement […]


Igår, måndag, gick jag på Rutabaga. Mathias Dahlgrens nya restaurang på Grand Hotel i Stockholm. Detta ersätter gamla restaurangen. Matbaren finns fortfarande.

Rutabaga är en helvegetarisk restaurang men inte vegansk. Menyn består av några drycker, både med och utan alkohol, samt en lista på rätter. Personal föreslår två eller tre rätter per person och […]

Security and things…

The polarized discussions related to “bad things on the net” continues. Everyone from the Prime Minister of Sweden talking about how powerful tool viruses controlled by the police would be, to the Anonymous attacking Daesh on the net.

I have been kind of silent the last week just because I have not had any idea […]

Caspar Bowden

On July 9 I was reached by the message that Caspar Bowden has passed away. What a loss!

I so much remember everything we have done together during the years related to privacy and integrity. Combination of ability for LEA to do their job and maximizing ability for people to communicate. Data retention directive. CSR […]

Facebook down?

I was checking a post I got a link to from a friend, and did not get any content, but the browser did not say anything weird. So I checked with the trustworthy curl library…

Presentations from the previous millennium

I have been asked, specifically lately(!) to re-publish presentations I have had on naming, searching, finding and such things. Yes, I was working quite a lot with those things in the 1990’s. At the KTH in Stockholm, at Bunyip in Montréal and then at Tele2 in Stockholm.

Some of the base ideas that you can […]
