The recent (and well-deserved) TLA+ attention motivated me enough to refresh my 20-year-old Haskell code that parses, pretty-prints, and evaluates TLA+ specs and expressions. Enjoy, copy, transcribe to other languages, etc. Maybe you too find it useful: github.com/ret/specifica

I'm happy to announce Thales, a TypeScript compiler and JS engine in Lean. Thales compiles a subset of TypeScript to Lean via a shallow embedding. I'm building a bridge for TS programmers into Lean's program verification toolset. Check out github.com/jessealama/thales to get started.

AI is writing a growing share of the world's software. No one is formally verifying any of it.

The CSLib steering committee recently announced the official launch of CSLib — an open-source effort to formalize computer science in Lean, inspired by the impact of Mathlib in mathematics.
CS researchers, practitioners, and enthusiasts are invited to get involved to support formalizing essential computer science concepts, and building infrastructure for reasoning about real-world code with Lean.

I created a short video about how Arch (the intelligent proxy for agents built on Envoy) can help with intent routing for smarter retrieval, guardrails for safety, and function calling for agent personalization via simple @FastAPIs. Of course, @Gradio is our natively integrated chat interface, and you can select from @MistralAI and @OpenAI LLMs for summarization (more coming soon)

I think I'm finally starting to get "virtual ground" with opamps.
Trying to work out the max (DAC+opamp) output voltage for the DIY AVR. Aiming for 2Vrms, to match the power amp input(s).
With this opamp setup, it will always strive to keep the voltage on both inputs the same.

We keep adding new customer value to our FIFO messaging products. 🚀 #aws #serverless #reinvent
Today, we announced two new capabilities for SQS FIFO queues:
1⃣ First, we increased its throughput quota to 70K messages per second:

Ok, that's pretty ridiculous. The throughput quota for SQS FIFO has gone up to 70,000 TPS!
Lots of throughput limit raises this re:invent so far.

New Amazon APIs for SQS redrive 😍
Just redrive to the original queue would have been nice. This is EXTRA nice because it allows us to specify any destination queue 😍😮
That's a whole class of Lambda Functions.... POOF, gone.
