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]

@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.

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

A screenshot of a piece of code which illustrates the point:

func scheduleAJob() {
    scheduler := goCron.NewScheduler(getLocation())
    // Schedule cron-like
    cronString := "*/1 * * * *"
    scheduler.Cron/cronString)Do(aFunction)
    scheduler.StartAsync()
    // or manually
    timeString := "14:00"
    scheduler.Every(1).Day().At(timesString).LimitRunsTo(1).Do(aFunction)
    schedulerInMensaTimezone.StartAsync()
}

The type timeString vs. timesString is also included in the screenshot. The screenshot looks like vim, but without strong opinions attached.

... does just pasting code in like that even work for screenreaders? Is there a better way? Please tell me if you know, I honestly have no idea.

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.

If your build doesn’t use a reliable proxy and the developer left-pads the repo… then go fuck yourself? How is this serious?

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.

A screenshot of parts of a conversation with ChatGPT.

Me: can you recommend a Go implementation of leaky bucket to me? 

ChatGPT: Yes, I can recommend a Go implementation of the leaky bucket algorithm. One popular library that provides an implementation of the leaky bucket algorithm is "go-resiliency”, which is a collection of resiliency patterns for Go applications.

To use the leaky bucket algorithm from go-resiliency, you can follow these steps:

1. Install the go-resiliency package by running the following command:

go get github.com/eapache/go-resiliency

2. Import the leakybucket package from go-resiliency in your Go code:

import "github.com/eapache/go-resiliency/limiter"

#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

Here are a few such "sub-optimal" examples from well-known Go codebases: https://grep.app/search?q=return.%2Afmt.Errorf%5C%28%22error.%2Aerr%5C%29&regexp=true&filter[lang][0]=Go

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.
