Some thoughts on my experience with helping B2B companies be more effective: AI Is Strategy. What About Your Culture? chadfennell.com/lab/3-ai-pro...

It's easy to get tunnel vision as an adult, particularly in a busy chaotic environment. We start hammering things into the shapes of previous problems we solved out of convenience and sometimes...despiration.

Woooooot!!!

An educational frozen dessert called "Popcyclical" that comes in the shape of Pope Leo with a wrapper that has the MAGNIFICA HUMANITAS Encyclical written in Dr. Bronner's font. Papa paparum est, poppa of poppas, Pope of Popes. #free_product_ideas

A Zoom plugin called "FATALITY" that allows you to murder one avatar a day. #free_product_ideas_thursday

TIL Firewalla's Wake on LAN implementation just works with my home dev box. I can wake it up remotely with a click on the Firewalla app.

At work, we got our app compiling without warnings on #ElixirLang 1.20-rc.6. The new type system discovered ~500 issues that 1.19 did not. - Most were just dead code (handling patterns that could never actually match in practice) - A handful were outright bugs. (See below)

GPT/codex has gotten pretty dang good.

Thanks, Vonnegut. 💜

🚨 Update hackney 🚨 A **bunch** of vulnerabilities I reported in hackney were just disclosed. Please upgrade to 4.0.1 ASAP. I know this is gonna start dependency hell so please take some time for this. Please RT for reach. #ElixirLang cna.erlef.org/cves/

Been on Kagi for a while now and I'll give up a lot of other services before I give up this one. No going back. arstechnica.com/gadgets/2025...

Hey Elixir friends, funny how getting a feature down to a simple one-line call takes two weeks of design work. Sharing what that looked like for Hologram realtime.

🚨 New Blog Post 🚨 I wrote about how I got into finding CVEs and what's the plan going forward. Also, I open-sourced the prompts I've been using. peterullrich.com/what-the-cve

PSA www.stepsecurity.io/blog/mini-sh... Tips and tricks: * Pin/Lag slightly behind new releases * Containerize your dev env * Use few & scoped env vars (e.g. 1Pass service account w/select vault access) * Build in team rotation & visibility (e.g. 1Pass hydration script vs static .env file)

rtk is an excellent way to reduce token spend for agents running shell commands like "find" github.com/rtk-ai/rtk Love it.

🚨 Update absinthe 🚨 Yesterday 2 CVEs for "absinthe" were released. The vulnerabilities can exhaust your CPU and atom tables. Update ASAP Thank you Curtis Schiewek and team for the quick fix and to @maennchen.dev for managing the release cna.erlef.org/cves/CVE-202... cna.erlef.org/cves/CVE-202...

I am loving this new addition to the home network. Fantastic user experience. firewalla.com/collections/...

If you were still unsure whether the Mythos announcement was just a marketing stunt: hacks.mozilla.org/2026/05/behi... Prepare.

If you’re running #Phoenix Channels (or LiveView) and have the LongPoll option enabled in your endpoint (default since 1.7.11), it’s time to do an update: github.com/phoenixframe... Thank you @peterullrich.com for finding and disclosing this issue!

If you're using plug_cowboy, update to the newly-released v2.8.1 to patch a denial-of-service vulnerability related to atom exhaustion. cna.erlef.org/cves/CVE-202... #ElixirLang

AI has not changed the way software is built. Code is written using the same syntax, version controlled using the same version control systems, compiled using the same compilers, deployed to the same servers, and neglected by the same developers.

A pair of raccoon butterfish in one particular bay off Kauai would mad dog me every time I got in the water last week. gopro.com/v/5cf4e6e8-7...

A fish skritching it's back on a Honu/green sea turtle gopro.com/v/96ac82d5-9... I shot this footage the other day on a GoPro while snorkeling off of the Napali coast of Kauai. I found myself alternating between chuckling and in complete wonder.

It's here! gleam_stdlib v1 released!

The v0.1 release of Expert (the new, official #ElixirLang LSP) is now final! 🎉 The best Elixir LSP experience keeps getting better. 😎 Tremendous thanks to all the contributors, and to Jump for sponsoring @katafrakt.bsky.social to work on this full-time. 🙏 github.com/elixir-lang/...

I like Ousterhout's ideas on deep modules and noticed Claude seems to expose a lot of functions I would keep as internal implementation details - so I had Claude build me a SKILL.md for deep module design.

NYC needs to do this. There are endless blank canvases.

Not saying they have nothing to offer but it's always a bit odd to me to see people making a career out of teaching entrepreneurship while never having started a business, let alone a startup - especially from the "ex McKinsey" crowd. "Creator of the StartupMethod TM" - former corp consultant

Hey Elixir friends! :) Elixir Gets JavaScript Interop - Hologram v0.8.0 is out! Use npm packages, call JS functions, work with Web APIs and Web Components - all from Elixir, with zero client-side latency. hologram.page/blog/hologra... #Hologram #Elixir #ElixirLang #BEAM #WebDev

It's still a shell of a library, but personally I'm really excited about it. BEAM nodes are easy to deploy near users, getting the data there as well has always been the hard part. Hopefully this solves that. For now, it's just me having fun with NIFs. #elixirlang github.com/bytebottom/t...

Good night sweet prince And flights of angels sing thee to thy rest He was perfection. RIP, my baby.

After caring for a sick cat post-ER I'm thinking about how patient discharge for pets is kind of broken. We're still getting paper handouts with hand-typed text instructions like it's 1975. IDK if my thing is a *thing* but I hope somebody solves this problem. www.linkedin.com/posts/chad-f...

This seems about right molochinations.substack.com/p/no-more-co... "A former coworker of mine, Michael Novati, the fastest coder at Facebook for years, had a day this February where he landed 417 PRs on GitHub. How long would it take you to review that?" 😬

The level of game for much of the user-facing software out there right now is so low that I expect vibe coding will likely improve affairs for a lot of it. And be at the price point Bob and Bob and Bob and Bob's Autoparts Direct wants to pay.
