Det blir #Halloween Meetup hos Gritera i Oslo torsdag 29 oktober, med oppmøte fra kl 16:30. Påmelding: send melding til meg. Som vanlig har vi en dedikert gruppe på Signal. Vi har en *skremmende* lyntale på plass allerede, men ønsker å få inn flere forslag.

No @adobe.com, I won't install your spyware intended to check if I am running cracked versions of your software. This for sure isn't to protect me from potential malware! Nag me again and my current license for Lightroom will end. Period. I've moved on to other alternatives for everything else.

AS5619 (my employer) now has valid BGP RPKI ASPA in place. Most do not know, understand or care. Me? Celebrating all alone.

Hey Americans & Canadians! It seems Apple Maps have caved to Trump's demand for "Lake Amerika", but only in the US. (screenshot from 08:06 Sept 2, 2026) Best regards from Norway

I will do a talk titled "Praise to the few and fury to those without: convincing Norway to do RPKI ROA & ASPA" at NONOG-8 in Oslo on September 9. I sincerely hope to see people from all Norwegian ISPs or organisations handling BGP towards the Internet in the room. nonog.net/events/nonog...

Skriv en falsk pinkode på betalingskortene dine. Da kan du lure skurkene som stjeler dine kort, varsle bankene og redde pengene dine. Enkelt og veldig lurt!

På #Personverndagene 2026 skal jeg holde kurs for å vise hvordan man kan gratis teste internett sikkerheten for egen organisasjon, leverandører og andre. Risiko vil bli forklart, nødvendige tiltak blir gjennomgått, og du får en sjekkliste med det du trenger til jobben. personverndagene.no

I'm sorry, but whenever I hear or see discussions about tactics etc in the FIFA World Cup on national news, this is what I think the reality actually is. Also: I seriously do not take any interest whatsoever in football.

Protip: add your name, address, alternative phone number & email to the lockscreen of your phone! In case you forget it somewhere, it will be so much easier for others to return the phone to you.

Here is a picture to describe the current situation in middle east.
Newspaper cartoon style image. Below a banner with the text "Peace means oil" there are rockets, drones and fighter jets flying across the skies, armed militia driving over a UN symbol, a peace dove is falling to the ground covered in oil and blood. A sign by the sea says "Strait of Hormuz", while the Iranian and Israeli president and a US "cowboy" president is pictured at each side.

Scandinavian Airlines (SAS) has launched Passkeys support, and they have chosen to call it "Hovednøkkel" in Norwegian. Directly translated to english = "Mainkey". 1) you don't have to remember a password. With "mainkeys" you can use stuff like fingerprint or face to login.

I've done something I thought I would never do. I've used Anthropic Claude to "vibe" code a Chrome plugin to test if a website is protected with DNSSEC & RPKI for BGP. Warning: it seems to work. USE AT YOUR OWN RISK! Feedback wanted. 😬 github.com/thorsheim/rp...

Well well well Google Chrome, is this how you have decided to treat @kalilinux.bsky.social all of a sudden, or do they have issues on their side, or is it just .... me? (Version 140.0.7339.208 official build on Windows 11)

Jeg er superhappy for å kunne annonsere at det blir meetup i lokalene til Advokatfirmaet CLP på Sommerrogata 13-15, 28 mai fra 16:30. Lyst til å delta og evt holde en lyntale? Kontakt meg ASAP. Lyntaler er morsomme, interessante og gjerne nyttige også.

So Microsoft makes everything so much easier with passkeys when you get these options: "Passkey in Microsoft Authenticator" or "Security key or Passkey"? And none of the options seem to work with 1Password? Thx for the screenshot @maximiliangolla.com!

May I suggest getting rid of password recommendations that expired with NIST SP800-63B in June 2017 @timcappalli.me? ;) I do hope & presume you support WebAuthn / Passkeys as well. 😁 (and have a great weekend!)

I am fascinated how #Midjourney with no notification deletes (censor) images I've created, long after I made & stored them. What is so incredibly wrong with "spitting image cartoon caricature" pictures? Have they never seen british tv or newspapers?
