First time Elixir live view app running on Android, update coming to elixir-desktop soon #myelixirstatus

@adust09 Oh there is, checkout Diode github.com/diodechain/ there is a chain, relay nodes, clients all in elixir, but also github.com/blockscout/blo… on of the largest indexers written in elixir and another client github.com/mana-ethereum/…

Elixir seems to be good for distributed systems, why isn’t it used in blockchain?

@josevalim @sasajuric I love that about the reference files. I'm doing the same in code review skills and of course the agents md. It would be awesome to have strongly opinionated defaults. E.g. "mix format" for agent coding guidelines

I have been complaining about AI-written tests for quite some time! We work with 5 different languages in Tidewave and all of them have the issues you mentioned. In some languages, AI also abuses mocks (like humans) and the tests have even lower value :S At least we rarely use them in Elixir. What I usually do is to have some test files as reference and ask the agent to use them as examples.

I recently reviewed some AI assisted code (Elixir). The core approach of the produced solution was solid, but I spotted a number of various issues: - Overly complicated module API - Too elaborate and subtly incorrect process structure - Redundant pieces of information in state - Too complicated and slow tests - Overlapping tests - Lots of subtle duplication between tests - Some tests were checking internal implementation details, not observable behavior - Some tests were never running (the execution was depending on a condition which was never satisfied) It was clear to me that it's not worth doing a standard review here. It would drag on for too long, and the code probably wouldn't be cleaned up completely. My typical approach in such situation is to submit a proposal refactoring instead. It took me the entire day (with AI assistance, more on that later), but I was able to address all of the issues above & more, shaving off about 500 LOC (from the previous total of 1000 LOC, which I'd say is not too shabby). I think that the key reason for the original state of the code was that too much code was generated at once without reviewing and steering the AI. So it ended up producing something which is technically correct, but may be overcomplicated in various ways. Reviewing and working with such code then becomes harder both for humans and machines. The approach I've been using so far is working in very small (really micro) steps. I ask the agent to make me a small change. Something like 100 LOC is about the capacity of what I can review reasonably well. I look through the changes, maybe do a bit of refactoring, ask the agent to review my changes and update its context, commit, and move on to the next step. I used the similar approach to refactor this code. Picked one issue, gave 2-3 sentences to the agent, checked the code, rinse and repeat. Most of my 44 commits were 100% AI generated, though for a few things I estimated it was quicker and easier to just make the change in the code. This doesn't give me dramatic speed improvements, it's more like 10-20%. But it gives me a good balance of velocity and code quality. In general, based on my admittedly small experience with AI assisted coding so far, I remain skeptical about the quality of the code, especially with larger LOC vs prompt size ratio. Though to be fair, I've certainly seen a lot of much worse codebases produced by humans than AI could ever make 😅 When writing production-ready code which is supposed to be maintained over longer period of time in a team setting, I still like to keep tight control over its quality. Working in small steps is my current way of doing it.

#myelixirstatus TIL There is `Phoenix.Component.update/3` turning ``` socket = assign(socket, :map, Map.put(socket.assigns.map, :key, :value)) socket = update(socket, :map, &Map.put(&1, :key, :value) ```

Our second Elixir Berlin event of the year 🎉 Two talks, lightning talks, drinks, and good BEAM vibes. 🎤 SSH OTP (Cara) · GenAI & text (Oren) 📍 Merantix AI Campus See you there 💜 #ElixirLang #Berlin #ElixirBerlin RSVP NOW: meetup.com/elixir-berlin/…

If you understand _______, you understand Diode.

@warmwaffle @_Mark_Atwood "/lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.34' not found" when running a new binary on an old machine. This is a glibc specific problem - but the reason for example I can't use your pre built sqlite binaries and instead have to force recompile using an old system.

@_Mark_Atwood Show me on the ABI where it hurt you

“C has no runtime” is a lie. It’s libc. Worst runtime in existence.

@josevalim Cursor embedded browser + module reloading

When quickly trying out changes to HTML/CSS on your web app, what do you use?

We are holding the December event in Unconference style. There is no lineup. we'll collectively together discuss what topic to talk/discuss about And like last year, there will be a competition! 🎄🍪🏅 #ElixirLang RSVP at : meetup.com/elixir-berlin/…

@xzensh @DFINITYDev Yes it's live in production in the Diode Collab app. Go to #download-app" target="_blank" rel="nofollow noopener">diode.io/download/#down… to get started. Happy to hear your feedback!

@DFINITYDev @DominicLetz Is this feature live yet? So far, I only know dMsg.net has integrated vetKeys—has any other product launched with it yet?

🎙️ Builder interview with Dominic Letz (@DominicLetz) from @diode_chain at #WCS25 💬 "Diode is one the first adopters of vetKeys so that all the data living in canisters are end-to-end encrypted."

Great podcast with @hotspotty, thanks for having us! Take a look as we explore the details of Diode, how it fits in with the DePIN ecosystem, and some of the ins-and-outs of how we keep it all secure👇

@marcadx Would love to organize a vibe coding meetup in Berlin. Will post progress...

Is anybody here in berlin?

vibe coding berlin edition

@diode_chain 新年快乐🥳

Welcoming the Year of the Snake! 🐍 Happy Lunar New Year to everyone, especially our Dioders in East Asia!

.@diode_chain provides a reliable end-to-end encrypted messaging and collaboration tool by utilizing #ICP canister #smartcontracts to store and transmit messages. Learn how you can join their beta 👇 forum.dfinity.org/t/diode-icp-zo…

@jasonmorton @YahsinHuang @therealyingtong This sounds amazing 🤩. We have some people in Taiwan as well building full self-custody community communications with Diode. Any way we can contribute?

Don't miss the chance to learn from @therealyingtong

Happy New Year everyone! That's a wrap for 2024. Let's build for 2025 #MyElixirStatus git-wrapped.com

@wojtekmach Love the PhoenixPlayground. There was a day I created this handy C foot gun called `Niffler` for your segfault pleasure. It snaps right into the example as well.

👀

@TylerAYoung Day and night. With copilot I would sometimes get a helpful autocomplete. But cursor (with Claude) changed the way I'm writing code day to day. When the Internet connection is gone now I really miss it.

Elixir folks, how's your experience been with Cursor AI compared to GitHub Copilot? #MyElixirStatus
