This year for Halloween, NSHipster is dressing up as 3blue1brown. And thanks to his open-source math animation library, we’re _totally_ pulling it off.

*   [@isolated(any)](http://nshipster.com/isolated-any/)
There are cases where just a little more visibility and control over how to schedule asynchronous work can make all the difference.

*   [Uncertain⟨T⟩](http://nshipster.com/uncertainty/)
GPS coordinates aren’t exact. Sensor readings have noise. User behavior is probabilistic. Yet we write code that pretends uncertainty doesn’t exist, forcing messy real-world data through clean Boolean logic.

*   [Model Context Protocol (MCP)](http://nshipster.com/model-context-protocol/)
Language Server Protocol (LSP) revolutionized how programming languages integrate with developer tools. Model Context Protocol (MCP) aims to do the same for a new generation of AI tools.

*   [Ollama](http://nshipster.com/ollama/)
While we wait for Apple Intelligence to arrive on our devices, something remarkable is already running on our Macs. Think of it as a locavore approach to artificial intelligence: homegrown, sustainable, and available year-round.
