Post 8 is drafted and sitting in my queue. Somewhere between writing post 1 and today, nexo\_ai went from whatever it was in July to 0.11.0, and nexo\_mail kept running against my actual inbox every day. Real mail breaks things a demo run never would. Before I publish post 8, I want to do something the series hasn’t done yet: go back and check what I already… ## [Wiring LiveView Uploads to Claude Vision](https://sublimecoding.com/blog/liveview-uploads-claude-vision) _2026-08-20 · Jared Smith · Jared Smith_ Boundary-validate uploads in allow\_upload before they cost tokens, then wire consume\_uploaded\_entries into Claude vision and PDF calls from LiveView. ## [An Introduction to Monitoring Design: From Purpose to SLIs](https://bmf-tech.com/posts/monitoring-design-guide/) _2026-08-20 · bmf-tech_ Start from "what signals can the monitoring tool capture" and you easily end up with plenty of alerts that nobody can act on.

Notes apps are the perfect subjects for endless fidgeting. I have a problem with notes apps. No app is perfect, and since the key functionality is so seemingly small in scope, they always feel like they are almost there. So close! I'm as guilty as anyone for blaming my lack of output on software. Right now I'm… ## [Most Security Controls Assume a Team You Don't Have](https://sublimecoding.com/blog/security-controls-assume-a-team) _2026-08-18 · Jared Smith · Jared Smith_ Security checklists only ever grow, because nobody who writes them pays the cost of a control a small team cannot staff.

Chrome doesn’t let you rebind its built-in shortcuts — ⌘P is wired to Print, Tab Search is wired to ⌘⇧A, and neither shows up in Chrome’s shortcut settings (chrome://settings/shortcuts). On macOS you can get there with App Shortcuts. You’re not changing Chrome’s internal bindings, you’re assigning ⌘P to the Search… ## [Interviewed by a High School Entrepreneur](https://robbyonrails.com/articles/2026/08/18/interviewed-by-a-high-school-entrepreneur/) _2026-08-18 · Robby on Rails_ Earlier this summer, I heard from Ojal Kulkarni , a local high school student who found Planet Argon through the Portland Startup Community Slack .

(plus other variations, such as "Are Ruby and Rails still relevant today?" and "Are Ruby and Rails dead?"). Are you stupid!?!! Obviously, if you ask such a question inside an online community of devs who make a living with these technologies, they are going to answer "yes" (to… ## [Ask the crowd: AI or not (Sponsored)](https://crawlproof.com/a/R5H3kqLTA5up) _2026-08-17 · **Sponsored**_ Get a transparent verdict from verified humans via web, RSS, or API. ## [Structured LLM Output in Elixir: Which Library, When](https://sublimecoding.com/blog/structured-llm-output-elixir) _2026-08-17 · Jared Smith · Jared Smith_ Four Elixir options for schema-validated LLM output, scored on maintenance, provider coverage, retry behavior, and escape hatches. ## [How to get help with Ruby questions](https://www.jvrc.ca/how-to-get-help-with-ruby-questions) _2026-08-17 · Javier Cervantes_ When you’re getting started it’s easy to get lost or you can get stuck when trying to work on an exercise or project.

I get the argument. But why then do I still prefer terminals for 80% of the work? I think it's the constraints: Terminals... have very limited space. You have to be diligent in showing just the essential info. are limited to (more or less) one-size plain monospaced text with a small color palette.

This caused a bunch of problems with my secondary DNS servers for TheLittleHost, as they suddenly did not recognise my hidden master server because its IP… ## [Driving a Porsche at Circuit Zandvoort](https://eremin.eu/blog/stories/driving-a-porsche-at-circuit-zandvoort) _2026-08-16 · Site RSS_ Reflections on driving a Porsche at Circuit Zandvoort with Race Planet, meeting Michael Bleekemolen, and why real experiences beat online reviews. ## [Weeknotes 268: Skill issue](https://elver.me/weeknotes/268-skill-issue/) _2026-08-16 · elver.me - everything (Atom)_ RubyConf 2026 Recap There is a new 'killer app' for Ruby I've been hearing that about Hanami and friends for a long time, but no one I know has used it or barely even tried it. I wish it were true. How we tracked down a 16-year-old SQLite bug - Lord, let me be so successful that I encounter a bug such as this.

One of the biggest obstacle that got me procrastinating was configuring the wireguard between my Home and my Datacenter. I needed to make sure that regardless of which direction traffic comes from, either one of the edge routers will be able to send traffic destined… ## [Meshtastic meets Tomagotchi: Long Range Mesh Radio Network](https://jch.github.io/posts/2026-08-15-meshtastic-tomagotchi.html) _2026-08-15 · Jerry Cheung_ Dennis (AD6DM) told me about Meshtastic before Defcon 34, so I bought 2 little radios from the merch area to try it out. If I'm being honest, what hooked me was the adorable 3d-printed tomagotchi 1 case and the custom firmware that gives you a pet to feed and take care of. The radio is cool too! Defcon was a great place to try it out because there were nodes everywhere, making it easy to trace how… ## [Add read-only permissions to your Rails API tokens](https://guillaumebriday.fr/add-read-only-permissions-to-your-rails-api-tokens?utm_source=rss&utm_medium=feed/) _2026-08-15 · Guillaume Briday's articles_ Slog app, my time tracking SaaS, exposes a public REST API following the JSONAPI specification.

A single malformed request killed the process that owned stdin, and the fix was not the one my OTP reflexes reached for. ## [Migrating JS from Yarn to NPM](https://cassey.dev/migrating-yarn-to-npm/) _2026-08-14 · Cassey Lottman_ In Ruby on Rails, the software ecosystem I predominantly work in these days, yarn has been the default package manager for the javascript side of things for a long time. (See my big write-up of the timeline & current state of frontend asset management in Rails ). When many of the apps I regularly work on were written, that was a pretty reasonable choice! Yarn had some solid advantages over npm… ## [Explain to me in Simple Technical English](https://allaboutcoding.ghinda.com/explain-to-me-in-simple-technical-english/) _2026-08-14 · All about coding_ Both phrases cut Claude's sentences in half when explaining code.

Recently I enjoyed a very good zine called "Clipart Crypt: a clipart fanzine", by Lee Arden. Lee is a zinester and small press runner I've gotten to know over the last few years. The zine was excellent; I encourage you to purchase a copy and enjoy it, too!

Just saying that upfront to avoid confusion! Coding agents spawn a fresh shell by default. That shell is usually set up slightly differently than how I set up ones I use… ## [Note](https://mikkelmalmberg.com/notes/01KZTMHY36MVJ8NVX3GS0ZBX4P) _2026-08-12 · Mikkel Malmberg: Everything_ Shut.

That is not a briefing. The same newsletter can arrive in two accounts, the payments are scattered across the files, the meetings are not in order, and there is no narrative tying anything together. I want one digest.json that is the whole picture, and a short inbox-digest.md for the terminal. The… ## [The Hard Part Was Never the Code.

All Ruby developers need multiple Ruby versions installed, as different projects may use different Rubies. For the past few years, I’ve used rbenv along with ruby-build to install and manage Ruby versions. They’re good tools, but I was using them more out of inertia than anything else. When it came to building Mimas , which is a tool to deploy Ruby apps… ## [Phoenix Secrets: runtime.exs, Fly.io, and LLM Keys](https://sublimecoding.com/blog/phoenix-secrets-runtime-fly) _2026-08-10 · Jared Smith · Jared Smith_ The compile-time trap in config.exs, why System.fetch\_env! should crash your boot, and how to actually wire Fly secrets and LLM keys through a Phoenix release. ## [Note](https://mikkelmalmberg.com/notes/01KZNS5MJKEVHM42BRF3BBZBAZ) _2026-08-10 · Mikkel Malmberg: Everything_ Amazing that with the right loop and a pad on the back, the models can just do the work completely by themselves.

Even in the age of AI, I like to write short custom scripts for my tool arsenal. One way to find subdomains of a potential hacking target is to initiate a DNS zone transfer. You can use various shell tools for this, but if it is part of a process(my case), it might be easier and more flexible to just script it in Ruby. I decided to use the dnsruby… ## [Not Every Curve Belongs in Sand](https://www.bounga.org/projects/2026/08/10/not-every-curve-belongs-in-sand/) _2026-08-09 · Nicolas Cavigneaux · Bounga’s Home_ Another CrunchLabs kit took over an evening: a sand table that drags a ball through sand on a polar arm.

Version 2 is rebuilt completely different than 1. 1 was tailored to devs. 2 is tailored to agents. How so? What’s the problem? Well, agents can build anything. BUT theyyy quickly lose grip on what components you have and which ones it should build again but slightly different. Do you know what makes a good dialog? Do you really want to discuss it with an…
