Harkn

Recorded a couple of tutorials to help onboarding in Harkn, and figured, why not just put them in a docs page?

For those interested in Harkn, these are glimpses into how it works too 👇

Some people ask, why not just email announcements? Email is a great way to distribute them. But you're faced with the blank-cc problem.

Wrote a bit more that here 👇

@ftes.de 🥳 you're always on top of things!

PhoenixTest v0.10.0 is released! It's got a lot of things, and (I think) none from me!

A huge thanks for all who contributed! 🥳

#ElixirLang

That's why in Harkn, I'm using tags/topics. People self-select into what they want to hear about. They subscribe to topics, and only they get emailed when the announcement is made. If anybody misses the announcement, they're all available to the team (so nothing hidden in a mailbox).

Interesting! I hadn't heard of JMAP. I still think the problem of "who do I send the announcement to" remains (though maybe that's not your point 😅). There's an information gap -- you need to know who would benefit from the announcement but don't want to spam those who don't care.

That's a great question! And... it'll be my next blog post 😄

The gist: I think email is amazing to deliver announcements, but you run into the issue of who to send it to (and occasional reply-all nightmares). And... the announcement is trapped in email -- no way for other teammates to discover it.

Slack vs Announcements

I've been thinking (writing is thinking, right?) about why Slack, Discord, etc. are a bad fit for your team's internal announcements.

It's not the right medium!

Elixir Friends Conversations about work, life, and other things with... Elixir friends. Inspired by the hallway track of ElixirConf.

Thanks for the ping Dennis. Sadly, Elixir Friends is dead. I could resurrect it at some point, but I think I was trying to do too much 😞

All the episodes exist in YouTube (👇), but the regular feed is probably dead.

Sweet #Ecto datetime helpers? Yes, please! 😄

#ElixirLang

Alright... it's all up now 🎉

I walked through the Phoenix 1.8 AGENTS md file, and it was both funny and informative!

You can see the full 25 mins of glory or in parts (on the same page) 👇

#ElixirLang

Getting back into recording **short** #ElixirLang video tips by recording a walk-through of @elixirphoenix AGENTS file...

It's ~25 mins long. I think I'm rusty 😅

Nice! That's good praise for them. That's helpful for me too. I keep trying to see if there's a pain in the community/market (enough of a pain). But if people are loving it, no pain. 😄

Is there anything that would make you switch to a hypothetical competitor?

Do you use anything for APM now? Or just nothing? And given that you love sentry (always good to know if people love the tools), what would it take you to switch to something else? (it's fine if "nothing" is the answer.

Anybody using #ElixirLang in production and doesn't like their error tracking service/APM service?

Would you be willing to jump on a 30 min call today and show me what you like/dislike about it? 🙏

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...

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

#AgileDevelopment

Got it. Yeah, I've seen and used that before in things like Sentry and AppSignal. I think they're called "deploy markers" or "release markers" or something like that. But super helpful for knowing when we've introduced new issues.

Thanks for all the additional context!

I like that. Makes total sense to me. Nice dev experience out of the box for development.

🤣

Nice. Thanks! I'll keep it quiet 😄

Interesting. Sounds like I'll need to reach out to find out more (if/when I do this 😄)

Yeah, I'm in the same boat. Part of me wants this:

[app] Elixir's telemetry -> [lib] (telemetry -> OpenTelemetry) --> [External Tool]

So, you don't have to use OpenTelemetry directly if you don't want to. Can use Elixir's telemetry instead. But we communicate in OpenTelemetry (if it makes sense)

Interesting! How would you use that feature? Do you add any specific metadata? And what does it allow you to do?

Thanks. Strange you can't see that anymore. But it's been a little while since I've used AppSignal in anger.

Do you remember what kind of information they had that was useful that you no longer get?

Nice. Love the "things we don't need". Super helpful too! 🙏

I'm assuming you use dependencies like those listed in opentelemetry.io/docs/languag.... Do you like the experience from Elixir's side?

I've often wondered if it wouldn't be nicer for me to report from my app with Elixir's telemetry, and the library translates that to OpenTelemetry stuff.

Do you like the current integration of Elixir apps with opentelemetry right now? (I mean the Elixir-side of adding open telemetry)
