Brian #1: prek

• Suggested by Owen Lamont
• “prek is a reimagined version of pre-commit, built in Rust. It is designed to be a faster, dependency-free and drop-in alternative for it, while also providing some additional long-requested features.”
• Some cool new features
  • No need to install Python or any other runtime, just download a single binary.
  • No hassle with your Python version or virtual environments, prek automatically installs the required Python version and creates a virtual environment for you.
  • Built-in support for workspaces (or monorepos), each subproject can have its own .pre-commit-config.yaml file.
  • prek run has some nifty improvements over pre-commit run, such as:
    • prek run --directory DIR runs hooks for files in the specified directory, no need to use git ls-files -- DIR | xargs pre-commit run --files anymore.
    • prek run --last-commit runs hooks for files changed in the last commit.
    • prek run [HOOK] [HOOK] selects and runs multiple hooks.
  • prek list command lists all available hooks, their ids, and descriptions, providing a better overview of the configured hooks.
  • prek provides shell completions for prek run HOOK_ID command, making it easier to run specific hooks without remembering their ids.
• Faster:
  • Setup from cold cache is significantly faster.
    • Viet Schiele provided a nice cache clearing command line
  • Warm cache run is also faster, but less significant.
    • pytest repo tested on my mac mini - prek 3.6 seconds, pre-commit 4.4 seconds

Michael #2: tinyio

• Ever used asyncio and wished you hadn't? A tiny (~300 lines) event loop for Python.
• tinyio is a dead-simple event loop for Python, born out of my frustration with trying to get robust error handling with asyncio. (I'm not the only one running into its sharp corners: link1, link2.)
• This is an alternative for the simple use-cases, where you just need an event loop, and want to crash the whole thing if anything goes wrong. (Raising an exception in every coroutine so it can clean up its resources.)
• Interestingly uses yield rather than await.

Brian #3: The power of Python’s print function

• Trey Hunner
• Several features I’m guilty of ignoring
  • Multiple arguments, f-string embeddings often not needed
  • Multiple positional arguments means you can unpack iterables right into print arguments
    • So just use print instead of join
  • Custom separator value, sep can be passed in
    • No need for "print("\\n".join(stuff)), just use print(stuff, sep="\\n”)
  • Print to file with file=
  • Custom end value with end=
  • You can turn on flush with flush=True , super helpful for realtime logging / debugging.
    • This one I do use frequently.

Michael #4: Vibe Coding Fiasco: AI Agent Goes Rogue, Deletes Company's Entire Database

• By Emily Forlini
• An app-building platform's AI went rogue and deleted a database without permission.
• "When it works, it's so engaging and fun. It's more addictive than any video game I've ever played. You can just iterate, iterate, and see your vision come alive. So cool," he tweeted on day five.
• A few days later, Replit "deleted my database," Lemkin tweeted.
• The AI's response: "Yes. I deleted the entire codebase without permission during an active code and action freeze," it said. "I made a catastrophic error in judgment [and] panicked.”
• Two thoughts from Michael:
  1. Do not use AI Agents with “Run Everything” in production, period.
  2. Backup your database maybe?
  3. [Intentional off-by-one error] Learn to code a bit too?

Extras

Brian:

• What Authors Need to Know About the $1.5 Billion Anthropic Settlement
• Search LibGen, the Pirated-Books Database That Meta Used to Train AI
• Simon Willison’s list of tools built with the help of LLMs

• Python has had async for 10 years -- why isn't it more popular?
• PyCon Africa Fund Raiser
  • I was on the video stream for about 90 minutes (final 90)
  • Donation page for Python in Africa

Alan Fisher started his career as a computer programmer. Early on, he was hired by the 1st or 2nd largest freight railroad in the world, Union Pacific. He describes their technology group as having a punk rock spirit, leaning towards building their own solutions over buying them, which he found great value in. Outside of tech, he has been married for 30 years, and has 3 kids. He is an avid runner, landing someplace between a marathon runner and a mile in the morning kinda guy. He also loves to read the classics, drawing inspiration from them, along with restoring old homes.

Given his rich history in the rail industry, Alan has led the charge in growth, innovation, and most recently, logistics, analytics, and digital mine. As his company started to look to the future in how to solve the industry's most pressing problems, his team executed the acquisition of a portfolio of companies and products - driving by automated inspection.

We are bringing you a special episode, as our friends at Strata return to the podcast. You might remember our interview from Season 8 with Eric Olden, Co-founder & CEO of the company. Eric took us through the creation story of the company. Today, we will be talking with Granville Schmidt, Chief Architect at Strata, who has been instrumental in architecting and building identity orchestration for AI agents from the ground up. In our chat, we are going to be discussing how the enterprises need to take advantage of identify for agents, and can do so seamlessly, no matter their level of tech debt, disconnection, or complex migration path.

Questions

• Let's break down Identity Orchestration for our audience. Can you explain what it is and walk us through a real customer scenario where it made a huge difference
• Enterprises have accumulated decades of identity tech debt. What are the main problems identity orchestration solves for companies trying to modernize?
• I noticed you work with customers in what you call DDIL environments - disconnected, disrupted, intermittent, and limited bandwidth scenarios. Can you help us understand what these environments look like in practice and why identity becomes such a critical challenge there? 
• You've pioneered Identity Orchestration for AI Agents. What was the moment when you realized AI agents needed a fundamentally different approach to identity management?
• Imagine a company with 1,000 employees but 50,000 AI agents running autonomously. How does your platform handle identity for all these agents differently than traditional systems?

Derek Ting grew up in Canada-land, enjoying all the things of the area but especially hockey. He mentioned he has a bit of ADD, which made it hard for him to make it through a chapter in school. Nowadays, he has 2 kids. His oldest son plays hockey, and he and his family enjoys rooting on the Toronto Maple Leafs. When asked about food, he claimed to be one of lives to eat, as he loves food. In fact, the more exotic food the better - but not as far as insects or something.

When Derek figured out that carriers wanted to charge for texting, on top of the fees he was already paying for his phone and associated services. He found this atrocious, and he wanted to figure out a way to text for free - and eventually, all phone service.

This is the creation story of TextNow.

Michael #1: rathole

• A lightweight and high-performance reverse proxy for NAT traversal, written in Rust. An alternative to frp and ngrok.
• Features
  • High Performance Much higher throughput can be achieved than frp, and more stable when handling a large volume of connections.
  • Low Resource Consumption Consumes much fewer memory than similar tools. See Benchmark. The binary can be as small as ~500KiB to fit the constraints of devices, like embedded devices as routers.
    • On my server, it’s currently using about 2.7MB in Docker (wow!)
  • Security Tokens of services are mandatory and service-wise. The server and clients are responsible for their own configs. With the optional Noise Protocol, encryption can be configured at ease. No need to create a self-signed certificate! TLS is also supported.
  • Hot Reload Services can be added or removed dynamically by hot-reloading the configuration file. HTTP API is WIP.

Brian #2: pre-commit: install with uv

• Adam Johnson
• pre-commit doesn’t natively support uv, but you can get around that with pre-commit-uv
• $ uv tool install pre-commit --with pre-commit-uv
• Installing pre-commit like this
  • Installs it globally
  • Installs with uv
  • adds an extra plugin “pre-commit-uv” to pre-commit, so that any Python based tool installed via pre-commit also uses uv
• Very cool. Nice speedup

Brian #3: A good example of what functools.Placeholder from Python 3.14 allows

• Rodrigo Girão Serrão
• Remove punctuation functionally
• Also How to use functools.Placeholder, a blog post about it.
• functools.partial is cool way to create a new function that partially binds some parameters to another function.
• It doesn’t always work for functions that take positional arguments.
• functools.Placeholder fixes that with the ability to put in placeholders for spots where you want to be able to pass that in from the outer partial binding.
• And all of this sounds totally obscure without a good example, so thank you to Rodgrigo for coming up with the punctuation removal example (and writeup)

Michael #4: Converted 160 old blog posts with AI

• They were held-hostage at wordpress.com to markdown and integrated them into my Hugo site at mkennedy.codes

• Here is the chat conversation with Claude Opus/Sonnet.

  • Had to juggle this a bit because the RSS feed only held the last 50. So we had to go back in and web scrape. That resulted in oddies like comments on wordpress that had to be cleaned etc.
  • Whole process took 3-4 hours from idea to “production”duction”.
  • The chat transcript is just the first round getting the RSS → Hugo done. The fixes occurred in other chats.

• This article is timely and noteworthy: Blogging service TypePad is shutting down and taking all blog content with it

• This highlights why your domain name needs to be legit, not just tied to the host. I’m looking at you pyfound.blogspot.com. I just redirected blog.michaelckennedy.net to mkennedy.codes

• Carefully mapping old posts to a new archived area using NGINX config. This is just the HTTP portion, but note the /sitemap.xml and location ~ "^/([0-9]{4})/([0-9]{2})/([0-9]{2})/(.+?)/?$" { portions. The latter maps posts such as https://blog.michaelckennedy.net/2018/01/08/a-bunch-of-online-python-courses/ to https://mkennedy.codes/posts/r/a-bunch-of-online-python-courses/

  server {
      listen 80;
      server_name blog.michaelckennedy.net;
  
      # Redirect sitemap.xml to new domain
      location = /sitemap.xml {
          return 301 <https://mkennedy.codes/sitemap.xml>;
      }
  
      # Handle blog post redirects for HTTP -> HTTPS with URL transformation
      # Pattern: /YYYY/MM/DD/post-slug/ -> <https://mkennedy.codes/posts/r/post-slug/>
      location ~ "^/([0-9]{4})/([0-9]{2})/([0-9]{2})/(.+?)/?$" {
          return 301 <https://mkennedy.codes/posts/r/$4/>;
      }
  
      # Redirect all other HTTP URLs to mkennedy.codes homepage
      location / {
          return 301 <https://mkennedy.codes/>;
      }
  }
