The last jump was from 3m to 1y. Showing up every day for a year is a huge commitment. This app did almost nothing to help me celebrate the success and then I immediately felt like the next 365d were going to be a slog. I’ve stopped. Not because of the app, but it didn’t help.

Reddit is not a terrible place to do business. Good marketing is offering a solution to a problem people have when they need it. When you do that, you can see good results anywhere.

The difference between girls and boys Mom to the girls, “help yourself to vegetables”. The boys get theirs dished.

Been digging through logs and picking up interesting bugs. Watching customers work with your software is a great source of learning. Error logs is another one.

So true “It’s tempting to fear AI slop, because it’s here and it’s going to get worse. But there’s human slop all over the internet, and it’s getting worse as well.” seths.blog/2025/09/wal...

If you want to bleed money, leave a few snapshots on AWS EC2 that you don’t need

There’s nothing quite as frustrating as a test that fails when running the whole suite but passes on its own.

Added configurable spam blocking to Mailcast.io You can now set the score at which to block spam. And you can see what’s being blocked in the logs so you always know what’s happening with every email.

I hate it when I know I’ve definitely solved this problem before, but cannot remember in which project 🤦‍♂️

Sometimes you only want validation to be applied if some condition is met. In one of my projects the first workflow step always runs immediately (0 days) and the rest have to be at least 1 day apart (>= 1 day), so I only wanted validation from the second step. #MyElixirStatus

My favourite email reply. Personal reply always. No AI automation

I had an hour and a half video chat with a customer who only bought a $2/m plan on Mailcast, but it was worth it. I watched them struggle. I identified where I had to point out things that I thought were obvious. Today I’m changing a bunch of UI based on that learning.

Just overhauled Mailcast’s test suite. Lot’s of global state in GenServers. Every test is now async: true and it’s ended up more reliable and twice as fast #MyElixirStatus #ElixirLang

You know you’re in “the zone” when you take a sip of cold coffee

My very almost six year old to me this morning, “Dad, have you already bought my presents, or do you need to go shopping today?”

Scopes in Phoenix make it much easier to add user specific, global UI elements (like an unread count) #ElixirLang #phoenix

Ah, that one commit that calms everything down 🍬

It’s always the assumptions that get you. Don’t assume. Test

I published an updated blog post on how to use Font Awesome (or any other SVG based icon library) with Phoenix and Tailwind 4 #ElixirLang #Phoenix andrewtimberlake.com/blog/2025/0...

Upward doing live upgrades in action Give it a try at upward.andrewtimberlake.com #ElixirLang #Phoenix #LiveView

I love how José manages Elixir. He makes you feel great when you contribute, even for small, seemingly insignificant updates.

Runtime config doesn’t play nice with hot code upgrades. But, I think I have a solution in upward. #ElixirLang

The problem with treating AI like a junior programer is that it’s not going to remember what I “taught” it tomorrow 🤦‍♂️

New greenfield project. Don’t even know what to name it yet. Working with Phoenix 1.8.0-dev, Tailwindcss 4, and gonna give DaisyUI a try at least for the initial prototype #ElixirLang

There is often a very simple solution. Sometimes it just takes time for it to surface

Add multiple hooks to an element with Phoenix LiveView I needed to add functionality to an element with an existing hook. I could add concerns to that hook or add a new hook (not possible). Now I have a single hook that delegates to two. #elixirlang andrewtimberlake.com/blog/2025/03...

I don’t think Bluesky can figure out what “this” is. I keep asking it to “show less like this” but my feed is still full of American politics

My mind is spinning as I’m trying to create a wrappable component in Phoenix LiveView I think I’ve got it though 🤯 #ElixirLang

Using Mailcast rewriting, I now have convenience aliases that forward emails to Evernote with appropriate notebooks appended to the email subject.

Playing with hot-code upgrades on a Phoenix LiveView app #ElixirLang

When I have to access a package via GitHub in order to use a fix before the next release, I always use a fork for a greater sense of security that things won’t change.

The problem with not doing Xcode or Android development very often is the long wait time while all the tools update before I can start coding again. ⏳

I need an in browser AI agent that will fill in a form with made up information based on form context for quick testing. Anything like this exist?

I was just about to reply to a customer email about how their request wouldn’t work, but, off course almost anything is possible. Google plus class="user-invalid:border-rose-400" and we’re there 🎉 🗑️📧

Add environment config to your Phoenix Javascript. Make sure latency simulation never makes it to production. #ElixirLang Blog post: andrewtimberlake.com/blog/2025/03...
