The Simplest MCP Example Possible in Python The post shows the simplest Python example of MCP (Model Context Protocol) for connecting a local LLM like Llama 3.2 to tools. It uses fastmcp and ollama packages with two scripts: mcpserver.py for time/date tools and ollamaclient.py to run the chat loop. https://inventwithpython.com/blog/basic-mcp-python-example.html

Introducing Retrace: Record Production Python. Debug It Backwards. Retrace introduces deterministic record-replay debugging for Python, allowing production executions to be recorded with very low overhead and replayed locally in VS Code with reverse debugging support. Instead of relying on logs or reproducing failures, it records the boundary between application code and nondeterministic systems like APIs, databases, threads, and file I/O, enabling deve... https://retracesoftware.com/blog/introducing-retrace/

Family Orienting Python Frozenset Dependent Type Theory The post models dependent type theory in plain Python by treating types as finite “families,” or dictionaries from contexts to sets, rather than as standalone bare values. The key idea is that full judgments like Γ |- A should be interpreted as mappings, which makes contexts, weakening, terms, Sigma/Pi types, and identity types easier to represent uniformly. https://www.philipzucker.com/dtt_python_family/

How we accelerated transpilation by compiling SQLGlot with mypyc Fivetran accelerated SQLGlot, a pure Python SQL parser/transpiler, by 5x through compiling 100+ modules into C extensions with mypyc, without rewriting it in Rust. Key optimizations included sentinel tokens, native i64 integers, dispatch tables, and upstream mypyc primitives for string operations, resulting in 3.9 to 5x speedups across the tokenizer, parser, and generator. https://www.fivetran.com/blog/how-we-accelerated-transpilation-by-compiling-sqlglot-with-mypyc

Boosting multimodal inference performance by >10% with a single Python dictionary Multimodal models are promising, but inference engines haven't been optimized for them yet. We profiled SGLang’s scheduler on a multimodal workload and identified an opportunity to replace expensive book-keeping around shared GPU memory with a simple cache lookup. Throughput and latency both improved over 10% on our target workload. https://modal.com/blog/boosting-multimodal-inference-performance-by-greater-than-10-with-a-single-python-dictionary
