The Dutch Parliament has instructed the government to keep DigiD data, the digital identification system, out of American hands. This comes amid concerns over data privacy and the potential for US government access to sensitive Dutch citizen information.

The article discusses the libbbf library, which is a C library that provides a simple and efficient way to read and write binary data. The library is designed to be easy to use and integrate into other projects, and it supports a variety of data types and file formats.

The European Parliament has frozen the EU-US trade deal in response to President Trump's threats to impose tariffs on the EU over the Greenland issue. The move highlights the growing tensions between the EU and the US over trade policy and geopolitical disputes.

The article discusses director Gore Verbinski's criticism of Unreal Engine, claiming it has led to a regression in movie CGI quality compared to traditional rendering techniques. Verbinski argues that the ease of use and accessibility of Unreal Engine has resulted in a loss of artistic control and a decline in the overall visual fidelity of CGI in films.

This article explores ways to slim down macOS, such as removing unused apps, disabling visual effects, and managing storage, to improve performance and free up disk space on older or less powerful Mac devices.

The article discusses the MAGA movement's belief in the economic leverage of the United States, arguing that this belief is a delusion and that the U.S. has significantly less economic power than many believe. It examines the misconceptions and flawed assumptions underlying this belief.

Canada announces its intention to distance itself from the United States politically and economically, citing divergent values and priorities between the two neighboring countries.

The German government has ordered Lexus to remotely disable the car heating function on specific models in the middle of winter, citing energy conservation efforts amid the ongoing energy crisis in Europe.

The article discusses the European Union's threats to use its 'bazooka' trade policy against the United States if the U.S. imposes tariffs on French products in retaliation for France's digital tax. The article also touches on tensions between the EU and the U.S. over issues like the status of Greenland and the future of NATO.

Former Bank of Canada and Bank of England governor Mark Carney calls for a new global 'social contract' to address the challenges of climate change, inequality, and the breakdown of the rules-based international order, urging for a rethinking of capitalism to better serve the public good.

A new shingles vaccine has been approved for use in the UK, offering improved protection against the painful condition compared to the previous vaccine. The vaccine is recommended for adults aged 70 and older, who are at greater risk of developing shingles.

A fork of Solar System Live that generates animated videos showing planetary orbits over any date range. Tracks orbital statistics (how many times Earth was lapped by Mercury/Venus, or lapped outer planets) and overlays dates/ages on each frame.

Example: Einstein's lifetime (1879-1955) showing 76 years of solar system evolution. Built with Python + Pillow + ffmpeg, runs locally with Lighttpd.

Comic Con International has banned the use of AI-generated artwork at its conventions, following backlash from artists who argued that the technology undermines their work and livelihood. The decision aims to address concerns about the impact of AI art on the creative community.

The article explores how Tesla has benefited from the attention and controversy surrounding CEO Elon Musk, while German automakers have faced challenges in keeping up with the electric vehicle market and Musk's disruptive influence.

Hey HN! I'm Fabio and I built UltraContext, a simple context API for AI agents with automatic versioning.

After two years building AI agents in production, I experienced firsthand how frustrating it is to manage context at scale. Storing messages, iterating system prompts, debugging behavior and multi-agent patterns—all while keeping track of everything without breaking anything. It was driving me insane.

So I built UltraContext. The mental model is git for context:

- Updates and deletes automatically create versions (history is never lost)

- Replay state at any point

The API is 5 methods:

  uc.create()   // new context (can fork from existing)
  uc.append()   // add message
  uc.get()      // retrieve by version, timestamp, or index
  uc.update()   // edit message → creates version
  uc.delete()   // remove message → creates version

What it's for:

- Persisting conversation state across sessions

- Debugging agent behavior (rewind to decision point)

- Forking contexts to test different flows

- Audit trails without building audit infrastructure

- Multi-agent and sub-agent patterns

What it's NOT:

- Not a memory/RAG system (no semantic search)

- Not a vector database

- Not an Orchestration/LLM framework

UltraContext handles versioning, branching, history. You get time-travel with one line.

Would love feedback! Especially from anyone who's rolled their own context engineering and can tell me what I'm missing.

Oban is a Python framework for building reliable and scalable background task processing systems. It provides a flexible and extensible architecture for executing long-running tasks asynchronously, with support for retries, priorities, and scheduling.

Two Social Security Administration employees were found to have violated the Hatch Act, which restricts certain political activities by federal employees. The employees were disciplined for their involvement in political activities while on duty.

We used our platform to fine-tune a tiny text-to-SQL model using distillation from DeepSeek V3. Repo has instructions for how to replicate this.

This is definitely not the best-performing model like this out there! But I found it surprising we were able to get to this much out of it: stone's throw away from a teacher 1000x the size!

We also ran the same thing using the 4B Qwen and matched the teacher accuracy, though here the difference is merely 100x :)

I find this pretty cool - obviously our distilled models can only do this one task and don't generalize, but that's often exactly what you want when you're building agentic systems.

Happy to answer any questions!
