Frustrated with the quality of our cell based internet lately I literally spent two days downtime writing a utility for scraping data asynchronously from the cell modem and charting it in a time series to help adjust the antenna to be more on-axis. It will never be ideal due to our range but it's been real bad lately. I successfully used it in a POC test to adjust the antenna with immediate feedback. #golang
#golang seems to be a great ecosystem, but for some reason I‘ve failed liking it so far, despite all the great things that Go offers.
I briefly discussed that with my co-worker Elisa (who knows way more about the more recent PLs than me) and somehow ended up giving Rust a try.
https://mmhaskell.com/rust was a great read so far. Let’s see if all the horror stories about using low level crypto libraries to validate a JWT are true :-)

When you sort your customers names in #Golang or any other language, please use your local collation system.
Let's say you have:
{"canaan", "Udo", "Óscar", "arudz", "bao", "Carlito", "Zoe","Álex"}
Standard string sorting:
[arudz bao canaan Carlito Udo Zoe Álex Óscar]
They are sorted by their precedence in the UTF-8 table. Ouch!
But we want this:
[Álex arudz bao canaan Carlito Óscar Udo Zoe]

@galdor @EMacAdie Emacs with Eglot (which is now part of Emacs) is a perfect #Golang IDE. You have the same Code intelligence, formatting, linting etc. because they are provided by #Go tooling, not the IDE.
I used to use Jetbrains Goland and VSCode in the past. They are very good but come at a huge price tag (money- or otherwise).
Emacs allows me to quickly jump between many projects during the day and never loose context. I often have to fix bugs, grep the code, fix it, commit it and deploy it - all from #Emacs.

But just discovery via GitHub.

Join us in ~45 minutes! https://gotime.fm/272/live
@uoxc gocron was the first open-source #golang project I contributed to. Sadly, it was for a feature that was later reverted - panic handling. I find it unacceptable to let a scheduler run without panic handling turned by default - keeping in mind that a single one is guaranteed to crash your entire app.
That and the fact that task functions aren’t required to return errors are two of the things that made me write my own scheduler. It’s about 100 LoC and much simpler but easy to copy around.

So, learnings, for those that care:
- Scheduling things at times is easy in #golang
- Sometimes "do everything in UTC" is a great aproach to avoid dealing with timezones. Sometimes it's the opposite
- Converting times without days between timezones is a headache
- Yeah I think that's about it for now

Let's start with ecosystem: Unlike with data visualization, #golang s ecosystem of "run this code then" seems mature. There's a healthy variety of both cron like schedulers, as well as "run this in x" libraries. We decided to go with https://github.com/go-co-op/gocron , which works great for running regular jobs at regular times. Syntax is intuitive: Pass in a cron-like string and a function, and then call StartAsync(). Alternatively, call functions to schedule stuff more manually. I'm really happy about the ability to schedule things in a certain timezone.
That's "how to schedule" out of the way, next up is "what to schedule". \1
For a #golang project I've recently had to impement jobs that run regularly at different times of day. In short, users indicate at what time they want their corresponding job to run, and that is when the job runs. (low 100s of users, all in one timezone, no strong realtime requirements) Short thread on how we did that, and learnings. 0/8

I just found out Go decided not to have a reliable standard package/module provider but instead it’s normal to just refer to a github repo and a version tag and Go will just… try to pull in that source.
This is pure clown shoes right? 🤡
If your build doesn’t use a reliable proxy and the developer left-pads the repo… then go fuck yourself? How is this serious?
For those of you in the overlap:
Was reviewing a player's #dnd5e character sheet today after a session, and after looking at some #pf2e resources a few weeks ago, I have decided that 5e rules are the #ttrpg equivalent of go library documentation format, which I find somewhat unusable if not hostile to casual use
Your #golang package is *not* well documented if the documentation is only available on some random site you linked to and not in the source code as godoc comments so my editor/IDE can show it to me. /rant
here's a snippet
func F(v string) {
for i := 0; i < len(v); i++ {
b := v[i] // panics here
// ...
}
}
Anybody knows how in the world this can possibly panic? #golang

Oh wow, #ChatGPT is really full of crap.
I asked it about whether it knows an implementation of the leaky bucket algorithm for #golang, and it describes a package and how to use it.
The problem: while the GitHub repository exists, the specific package (.../limiter) does not, and never has, I even checked the git history.
So, ChatGPT will just hallucinate non-existing Go packages and even a plausible API including example usages.
Moving forward, I don't think I will have the capacity of managing both https://goingwithgo.com/ and https://java2go.dev/
It is becoming clear to me that one has to go, allowing me more time to focus on the other (and my family life and day-to-day work, ofc.)
I would really like to choose the one that is going to be more useful for the #golang community in the long term. So, please help me decide. Which one do you find more helpful?

#golang tip: When wrapping an error, don't use words like error, failed, cannot, won't, etc. It's redundant and only adds noise to the error message. Imagine the same error being wrapped 10 times, and every wrapped message starts with "Error:".
To provide maximum context, explain what you were trying to do when the error occurred: https://java2go.dev/docs/topics/errors-and-panics/#error-messages

Is there a way to make the #golang compiler warn about unused return values from some interface method?
Specifically I have an interface similar to the builtin append(): MySlice.Append(val) returning a MySlice. If users of MySlice do not use the return value they might have a tricky bug. I know C compilers have provisions for this...
I used to think #Golang lacked generics. But in practice I never really needed them and interfaces did the job. Now that generics are here I'm seeing more and more complexity, courtesy of architecture astronauts. Hopefully Go won't become the Java of Google.
