I'm joining Berget AI, an AI platform based in Sweden that offers sovereign AI infrastructure for European organizations.

I'll be focusing on developer experience and helping teams build with AI without compromising their data.

Are you evaluating AI infrastructure in Europe? Let's connect! 👋

Grafana dashboard showing ad blocking metrics, such as total and blocked queries.

Got around to replacing NextDNS with Blocky for my home lab.

Considered options like Pi-hole and AdGuard Home, but I kept coming back to the simplicity of Blocky and being able to version-control the entire configuration.

I love being able to export my configuration as text and just ask Claude whenever I mucked something up.

Got my first #Mikrotik router this week and I’ve honestly had so much fun migrating my home network (no, seriously!)

Been wanting to segment my IoT devices for a while, and I even managed to replace Tailscale for all my devices.

Last chance to turn it off.

On Monday, November 3rd, Microsoft will start using your LinkedIn data for AI training. And remember, you're opted in by default.

The downside is I'd need to create announcement posts retroactively if I wanted to support comments for older blog posts.

I’ve seen similar solutions that source comments from GitHub issues, but I love the idea of using open protocols for this.

Of course, rate limits apply, but I should be so lucky to actually hit them 🤣

Finally got around to adding a comments section to my blog posts, powered by Bluesky and Mastodon.

For each blog post, I create announcement posts on each platform and add the links to the posts in the front matter.

The replies on each post are then fetched client-side and interleaved.

Love to see in-person privacy controls 🤗

Personally, I don’t mind having my photo published, but I also want to relax and enjoy the event without having to think about cameras.

Ever notice how #privacy controls and other opt-out mechanisms seem to have a curious proclivity for errors?

There's a special place in hell for teams that change the title of their website when you move to another tab.

Suddenly I have 10 tabs, all with the title "Please come back! 🥲 ".

Today I even saw one that BLINKED! 🤯

I don't care how great your website is, I'm closing your tab.

Piece of advice: While phrases like ”X just killed Y” might generate impressions, they’re more likely to harm your credibility.

Published: Intro to Westin's four states of privacy

I'm currently studying for the CIPT certification, and struggled to find resources on Alan Westin's work on the four states and functions of privacy. So I decided to expand my study notes into a blog post 😊

Here's how longer-lasting smartphones will soon become a reality New EU rules mean longer-lasting smartphones and tablets will soon become a reality as well as being more easily repairable.

Longer‑lasting, repairable smartphones are now a thing in the EU! Since 20 June 2025, EU rules require smartphones and tablets to meet strict ecodesign and repairability standards, with mandatory labels showing battery life, charging cycles, repair-score, durability, and water/dust protection.

Open AI’s valuation is at $400 billion. They used about 190,000 books to train their plagiarism bot. Randomly saying 25% of their value comes from that stolen dataset, I think they owe the authors about $526,000 per stolen book.

So wild to see those dipshits try to bully Zelensky, who’s shown a level of bravery that they’d be incapable of.

Ukraine is Europe!
We stand by Ukraine.

We will step up our support to Ukraine so that they can continue to fight back the agressor.

Today, it became clear that the free world needs a new leader. It’s up to us, Europeans, to take this challenge.

OpenAI Says DeepSeek Used Its Work Without Permission to Create an AI That's Stealing Its Job After spending years indiscriminately ripping off other people's work, OpenAI is trying to pin blame on Chinese AI startup DeepSeek.

somehow this is not an Onion article: OpenAI, which built its AI by stealing everything on the web with no credit, says that DeepSeek stole that pilfered work to make its own AI that's now eating OpenAI's lunch

If you are using Signal or other messaging apps: a gag order by the US government was just rendered ineffective, and Google and Apple have both confirmed that governments have been using the unencrypted contents + metadata of push notifications to spy on us! 
So if you use Signal, for example, be sure to change this settings (other apps may have similar). Setting for Notification Content set to "No Name or Content".

The gag order was lifted in late 2023 - so I'm coming at this late, but this is the first I'm hearing of it, so sharing in case others didn't know.

In Austin for the first time, and while there are many things I enjoy so far, I’m struck by what I can only describe as a vegetarian minefield. Innocent looking salads with bacon fat, beautiful smoked cauliflower coated in anchovy.
