Vi behöver fler politiker som tar teknik och innovation till sig, inte färre. De stödfunktioner som finns, som säkerhetsavdelning på Regeringskansliet, måste hänga med. Men att som ryggmärgsreflex säga @SwedishPM gör fel när han använder AI, det är fel väg framåt för Sverige.

Thanks @BBC for getting these questions asked. In Russian, in Russia. Those answers explains a few things.
My first opportunity to ask Vladimir Putin a question since Russia’s full-scale invasion of Ukraine. It came at the end of the BRICS summit in Kazan. Producer @LizaShuvalova

När något händer är frågan: Är du en ja- eller nej-människa? Om du frågar mig ska du vara en ja-människa. Annars, eller om du ens funderar, kommer du agera långsamt, och det är något ingen har i sitt uppdrag. Att vänta. Vilket bl.a. @MSBse och @CarlOskar påpekat.

I was interviewed earlier today about the CrowdStrike incident. My view is that we have multiple findings. Here is the interview, in Swedish, one that we are lucky, another that we today are part of a system of systems without recognising it: omni.se/ska-inte-kunna-handa…

Kan någon hjälpa till så hör av er. Återigen, opolitiskt, lösningsorienterad diskussion!
(Sw) Hej Tweeps! Vem är i #almedalen i morgon och styr upp inspelning av Chat Control-seminariet?

Hjälp! Hur löser vi snabbt utsändning imorgon, åt Niels PaarupPetersen, så han hinner? En billlig mobil? Bara ljudet (det räcker). Hur får man ut det med bandbredd, kan man tanka från mobilen till youtube i realtid? Youtube klarar bredden till resten av världen.

Jag har jobbat med @mer__edith genom åren, lita på henne. Dessutom förklarade jag och Stephen Farrell redan 2021 varför chatcontrol inte går att göra. Här skriver journalist Monika Ermert hos CENTR centr.org/news/blog/ripe82-e…
(Sw) Om ni vill prata teknisk genomförbarhet av Chat Control i #Almedalen rekommenderar jag starkt att bjuda in @patrikhson från @netnod till era evenemang. Han är på plats och har viss tillgänglighet fortfarande.

Welcome to @netnod @mpawlo!
I am honored and humbled to have joined the board of directors of @netnod. Netnod is a Swedish foundation-held organization that provides critical Internet infrastructure services. With 25 years of experience at the core of the Internet some of things Netnod does are: 1. Internet Exchange Points, IXPs // Netnod operates several IXPs in the Nordics, facilitating efficient and high-speed data exchange between different Internet Service Providers (ISPs). These IXPs help reduce latency and improve the performance of internet services by allowing traffic to be exchanged locally rather than routing it through international networks. You don’t want to play Fortnite without IXPs! 2. DNS Services // Netnod provides DNS root server operations, hosting one of the 13 root server clusters. It also offers DNS anycast and unicast services, enhancing the resilience and performance of DNS resolution for its clients. You don’t want to surf the web without root servers! Then you’d probably just stay at 127.0.0.1 or ::1 if you speak IPv6 - as you should! 3. Network Time Protocol (NTP) Services // Netnod provides accurate time synchronization services through its NTP servers, which are crucial for various applications requiring precise timekeeping, such as financial transactions and telecommunications. Use Google search for ”Knight Capital” to learn how to lose 440 MUSD in 45 minutes due to poor time stamps! 4. Internet Infrastructure // As a trusted infrastructure provider, Netnod plays a significant role in ensuring the stability, resilience, and security of the Internet in Sweden and beyond. It collaborates with international organizations to enhance global internet infrastructure. …Or in summary: don’t fxxk with the Internet! A picture of me with a T-shirt the Swedish Internet museum gave me with my handle and the year I first was active on the net in its current form (not counting Fidonet and BBSs):

Thank you for all work you and all brave people in Ukraine is doing. The best we can do on distance is to support you. And we will continue to do so. In the small and in the large.
During my audience with King Carl XVI Gustaf of Sweden, I expressed gratitude to Sweden and the Swedish people for their unwavering solidarity with Ukraine. We particularly appreciate Sweden's significant assistance to Ukrainian children, including through the International Coalition for the Return of Ukrainian Children.

Det är intressant att arbeta med projekt som visar sig vara som man säger ”mitt i prick” givet statsaktörers agerande i Sverige genom understöd av kriminalitet enligt dagens presskonferens.
I @KKrVA_Sverige nya studie SVAR - Svensk avskräckning och resiliens - har jag förmånen att leda ett dussin kompetenta personer i delprojektet hybridoperationer. Ramen kring projektet är Sverige i EU och Nato, där kollektiv säkerhet är A och O. 🧵

Russia needs to lose, and lose badly. That's what every dictator on the planet needs to see. Our ability or failure to stop and punish Russia's crimes in #Ukraine will deter or encourage the aggression of dictatorships worldwide, and thereby determine the course of this century.

50 years ago today @vgcerf and Bob Kahn published their paper on packet switching which is the basis for the Internet we use today. It was published in IEEE Transactions on Communications ( Volume: 22, Issue: 5, May 1974) cs.princeton.edu/courses/arc…

En grym lagledare! 💪🫡 Helt klart en upplevelse utöver det vanliga:
New sticker dropped! 😅 Helt galet intensivt, givande, meningsfullt, relevant och framförallt bland det roligaste jag gjort! 😀 xitter.cf/patrikhson/status/1783…
