What happens when you point a coding agent at a real, messy codebase and ask it to sort out the dev environment? Justin wrote up the whole experiment, including what worked, what broke, and what the skills did about it 👇 buff.ly/XCNqiur

Planning in software development has had artifacts and ceremonies that serve a purpose. This is a great summary of strain from AI-generated artifacts and pressure to adopt AI and what it does to erode a long-time carefully constructed culture of writing 6-pagers at Amazon.

Writing Crystalized Thinking At Amazon. Is AI Muddying It?
Amazon’s famously writing-centric culture is being aided by generative AI. What does that say about the company’s culture, priorities, and future?

I've had an open tab for a few weeks (link in comment) that AWS added RDS and Aurora instance type recommendations to the AWS Compute Optimizer. It's pretty wild that you can save somewhere around 10% across a big variety of database instance types.

James Bayer @jambay.bsky.social · 04/07/2025
Quoting from the post: "In layperson’s terms, ZKP makes it possible for people to prove that something about them is true without exchanging any other data. So, for example, a person visiting a website can verifiably prove he or she is over 18, without sharing anything else at all."

I believe in user-controlled privacy. I'm very disappointed in the lack of privacy laws in the United States. I love seeing this update from Google that they have open sourced a Zero Knowledge Proof library that can be used in support of technology standards that preserve privacy.

I tried Wispr (wisprflow.ai) as a voice input method today on my Mac and it works really well. I really like the UX. They've done a nice job with it. MacOS Dictation also works decently so they'll have to be a lot better than that for it to really catch on.

Citing your sources is so important. I researched cloud network pricing and ChatGPT confidently told me that Azure charges from cross-AZ traffic within a Virtual Network. I thought changed, so I checked. Azure made cross-AZ traffic free in May 2024! Check the citations of these chatbots!

Today I transfered a domain name from Namecheap to Cloudflare. The name says it all, they should be cheap, but they charge 70% more than Cloudflare for a .com! Even though I had to divert time to do it, it's a principles thing to me. The internet, cable, and phone providers all do it.

I disagree about Cursor, the product excels at the experience of exposing the power of the models and supplemental info (RAG, MCP) in an optimal way. They can differentiate on experience and then build momentum to create other moats.

Got my first local MCP server example running today in Claude Desktop. The tutorial is pretty straight-forward. modelcontextprotocol.io/quickstart/s... I've seen some criticism from people I trust that MCP will be like SOAP and ws-*, but so far looks like it's enabling some cool integrations.
