I asked Delaney Gillilan to return to go podcast() to revisit datastar, a very impressive tool that enable backend to push changes to the frontend of a web application. In episode 54 we covered the "what is datastar", in this episode I wanted to dive a little deeper since I personally finally started to jump and use the library in projects. I have been a dedicated user of HTMX and Alpine for a long time already and once I tried datastar I found myself capable of great interactions between the frontend and backend and mostly keep the state that made sense in the backend. It's hard to explain, you'd have to test it to realize it's true power.

This week I try to keep an open mind and we talk LLMs and AI with Markus Wüstenberg. Markus is a friend of the show and I noticed he was using a lot of LLM lately, I basically learn a lot by doing these podcast interviews, so I was interested to hear about what Markus is using LLM and AI in the systems he ships and also how does he uses AI as a software engineer in the day-to-day.

Personally my experience so far is very mixed, sometimes it's good other it's pretty frustrating with LLMs either integrating functionalities augmented by LLMs or trying to integrate a coding agent in my day-to-day, let's just say that I'm not there yet. But I wanted to hear about someone that do have real production experiences using these things, and Markus gives a solid fundation to demistified some aspects, at least for me ;).

Jon helped a lot of teams improve their software engineer processes. We talk about the importance of testing, having sane Ci and CD pipeline, pairing and a lot of other extreme programing concepts.

My desire to run a sustainable software business started somewhere near 2003 in the Business of Software forum. I've built, sold, and acquired a dozen of products since that time, with I have to admit the majority of failures.

I've seen three distincts era for software companies, we're definitably in the 3rd one, one that still has to be identified as good or bad.

Software companies, especially calm company is excruciably hard to be successful at. But when you're honest and define what is success to you and set out realistic goals, there's ways to succeed even without have $2m in ARR.

Go is of course a great choice to build a SaaS, but software product has almost zero to do with technology, especially at first and you'll most certainly end up rewriting to a v2 at some point after learning what the product really need to be. So the good old advice of use what you're most proficent in to write code is most often than not the correct answer.

I talk about my experiences trying to run a sustainable software company for the last 17 years.

I retried Podman to replace a production service and did not wanted to re-installed Docker, mainly for security reasons. The fact that podman runs containers on the user-level and completely isolated from the system is a great alternative to the Docker deamon.

I'm trying something new for this episode, I'll try and get audio clips from people to add more dynamism to the episodes, if you can join the Slack channel and also I've started a Patreon if you want to chip in and help me keep the mic on.

Jakub is returning to the show, he's about to launch a book called "50 Go Testing Mistakes" and we talk about the most common mistakes Gophers are making when it testing. Having a trustable testing suite is known to be critical for long-live software system. I can testify having maintained a .NET codebase for 20 years without any tests, it sucks.

One university published attracted my attention, because it was on Go, it's titled: "Assessing Golang Static Analysis Tools on Real-World Issues".
Do you find your static analysis and linters tools could be more helpful when reporting issues?
I'm mixed feeling really, I think that they're pretty damn good. Tools can always improve for sure, not sure if we will need the help of LLMs to mix static analysis checks and LLM analysis / proposed fixes, maybe that will be the next step for those tools.

I finally gave Gleam a serious look and ho boy I'm excited. I've looked at Gleam a long time ago back when it started with the ML-like syntax. I've always been an Elm fan, I discovered functional programming with Elm. Near 2016-2017 I tried Elixir and Phoenix, and gave it a try multiple times following the years, but I'm not fully sure why it never clicked completely for me.
As someone engage with Go for the last 10+ years, I won't lie that I was looking for some excitement lately. Not because I'm tired of Go or anything, I've dabbled seriously into Python/Django in the last 3-4 years. But Gleam, at least so far, as this I don't know what that I felt when I started Go back in 2014.
There's so many programming languages these days that I suppose it's really comes down to a matter of taste. I do have some minimal checkboxes that a language must checked before I even considered looking at it, and Gleam was checking them all. It's a refreshing language after 10 years of Go. Just another tool in the toolbox, but I'm extremely picky about which tool I put in my toolbox haha, so Gleam for now is in the evaluation phase, but so far I'm excited and I haven't felt like this for a long time.
