Looking for an #ElixirLang dev? I'm officially on the market!

4+ years of Elixir in production. Natural affinity to testing, o11y and DX. My most used OS libraries are InstructorLite and PostHog SDK.

Remote from 🇨🇦, PDT, links in bio.
RTs appreciated 🙏

@0xAX nah don't use AI for this, naming domain belongs to humans and favors bold ideas! https://t.co/uZHme2rbol

[Alex Martsinovich @distantprovince]

Naming is only hard because we're not bold enough. If an OTP engineer can name a function `try_steal_task_from_victim`, you can too!

[Alex Martsinovich @distantprovince]

Almost disappointing that none of my OS projects issues any new warnings on 1.20 😅

[José Valim @josevalim]

Elixir v1.20 released! Now officially a gradually typed language: Elixir type checks every single line of code, finding bugs and dead code, without developer overhead (no typing signatures) and extremely low false positives rate. Plus a faster compiler! Links and reports below.

[Alex Martsinovich @distantprovince]

I once again have some extra free time on my hands, so I'm going to dig into why DBConnectionErrors are seemingly never grouped correctly and see how many yaks require shaving.

Our first stop is naive `Logger.error` calls. We need to figure out what to do with them! https://t.co/nkeNxTa10x

[Alex Martsinovich @distantprovince]

You can just yak shave things

@max_spero_ Humans are ends, while AI will always remain a mean

[Alex Martsinovich @distantprovince]

The problem is that you won't know if a patch is good quality until you already read it. So the cost asymmetry is very skewed in favour of the contributor vs the reviewer.

Basically, people are asked to spend some demonstrable effort upfront, so that maintainers knew they can spend their effort too.

📡 New Blog Post

LLMs looove markdown, but the best chat interfaces go beyond and let models use rich UI elements. In this post I demonstrate one possible way to achieve this: by teaching models to use custom HTML elements

[Alex Martsinovich @distantprovince]

People talk about LLMs discovering and fixing bugs like it's normal and inevitable part of development process. But it's not!

Ask your QA, they know that bugs aren't finite set of issues waiting to be uncovered, but more like a quality gauge. If you see a lot of them, then even more have not been discovered, and you might want to step back and reconsider.

Sure, some bugs are normal, but they're a valuable signal first and foremost.

@josevalim This is a huge loss for us all 😭😭😭

[Alex Martsinovich @distantprovince]

Code reviews are definitely dead and many of us, including myself, are grieving. I don't know how things will turn out, but I felt the need to write a farewell. ⬇️

[Alex Martsinovich @distantprovince]

@ZachSDaniel1 Agree, I think non-anthropomorphizing ways of working with LLMs are very underdeveloped. It doesn't help that LLM providers pretty much locked everyone into the chat completions API 😢

For a lot of people it doesn't seem very healthy to frame AI this way https://t.co/ZO6CNEfouk

@keysmashbandit let's make it run on elixir 🌚

[Alex Martsinovich @distantprovince]

I talked to people using AI in real industry today and it is so refreshing. There are absolutely good uses for AI!

[Oskar Wickström @owickstrom]

Maybe I'm dating and deprecating myself in a single stroke, but I genuinely struggle seeing a productivity increase from agentic coding. I try, I retry, like every 2-3 weeks. I always end up tired and slow, either from hand-holding in real time or spending hours undoing the slop.

[Alex Martsinovich @distantprovince]

Codex really takes Phoenix default AGENTS.md to heart

[Alex Martsinovich @distantprovince]

fixes to MDEx streaming are next 🫡

I decided to clone ChatGPT with LiveView as an exercise and am now week deep into yak shaving. 10/10 would recommend

[Alex Martsinovich @distantprovince]

First results are merged! https://t.co/ai9lcmYpD2

[Alex Martsinovich @distantprovince]

@ZachSDaniel1 They won't even have to hear the second part 🌚

[Alex Martsinovich @distantprovince]

I keep thinking about this approach. I think peoplemight be more deliberate in their AI use if they have to do it publicly
