I have to prototype a webapp with a colleague. I only know Phoenix, so he will read up on Phoenix. He just sent me this. #elixirlang

Don’t let the age of this article from @germsvel.com scare you off, vertically slicing features is still a great idea:

Break apart your features into full-stack slices
Our communication practices can be very disrupting. Remote work has taught me to be more considerate of how I communicate with others. We should treat other people's time as we like ours to be treated...

PSA!
It's so easy to forget to handle websocket reconnects in LV, but if you're deploying regularly, your users are likely seeing A LOT of bugs coming from this.
Go to one of your pages, click around a bit, then run `liveSocket.socket.triggerChanError()`, and see what happens.

I'm closing out, for now, my series on questions at the heart of development with an analysis of when we need more abstraction. For example, taking @germsvel.com's advice about architecting more accurate models can reduce future bugs.

I made an Ash extension!
Elixir is capable of hitting services hard; great for throughput but harsh when those services are trying to recover from an outage.
The circuit breaker pattern addresses this issue and is now available in Ash!

Long time ago newspapers aren't bombarded with ads, until realized. Same thing with tuning to radio stations. Same thing with TVs. Years ago, "Googling" shows little to no signs of targeted ads, until it's realized they can abuse cow's milk. Still, same thing for AI.

"LiveView does the same thing as Eclipse RAP 15 years ago"
"Unusable as soon as there is network latency"
Great comment I heard yesterday at #jugpb talk on #elixirlang
Offline mode? Latency >500ms -> Don't use LiveView
Most business SaaS incl. mobile -> Use LiveView
Let's dig deeper 👇

In #Phoenix #LiveView v1.1.0-rc.0 we shipped `:key` support for comprehensions in HEEx. The idea was to finally be able to have change tracking in comprehensions. We did this by leveraging LiveComponents. Sounds easy enough, right? There were some problems though. A thread. #MyElixirStatus

I kept telling ya'll: As much as you can, please self-host. Remember glitch.com? Of course you'd end up having paralysis analysis or a legacy app in a few years.

Talk is cheap. There's a difference between knowing something can be done and having done so. Sometimes you just have to externalize the thoughts by implementing them. Zero downtime upgrade of a server-side rendered animation of SVG.

It would be great if #OTP and #ElixirLang releases were better coordinated with Docker Hub and GHA - current situation: OTP 28 breaks a lot of Elixir code, our Sentry SDK is broken, there are a couple of fixes needed and we can't yet run our test suite on GH as there is no OTP 28 there yet.
