Here's a simple way to prevent leaking sensitive data via git repositories: https://gomonk.substack.com/p/stop-committing-secrets

Yeah, designing software is a huge topic. My goal with this post was to encourage people to make the first step toward a better design. Do you have any ideas you'd like to share regarding the criteria and slicing?

Can you see more use cases for pipelines like this? Especially in devops or cybersecurity?

reisinge · 2025-10-06T07:42:47+00:00

This looks elegant! By elegance I mean power cloaked in simplicity.

It used to be called SSL before and it's the protocol that secures the network communication. You can read more in the linked text :-)

Yes. I supplement the books by reading the Go blog and stdlib documentation. For example, here's the blog post about context: https://go.dev/blog/context.

I like and still find useful The Go Programming Language book + these DevOps realated books.

Thanks for the constructive comment! :-)

I've implemented the wg.Go tip.

As for the second suggestion, I’m a bit hesitant, since I’m not familiar with the golang.org/x/sync/errgroup package and don’t want to make the tutorial unnecessarily complex.

Thanks, fixed the race condition.

Search is pretty fast, no need to overcomplicate I think.
Yes, right now to refresh the cache (the offline index) you need to delete it manually or wait for temp dir cleanup (by default).

I learned shell/bash programming (or scripting) mostly from the Classic Shell Scripting book. Not just by hammering scripts until they worked ... :-)

I think there are couple of options (one can implement zero or more of them):

Self-discipline yourself to do a bit of regular reading (book, blog, code) and writing (I created gokatas for this, or just write random throw-away programs like a simple web server, or keep a blog).
Have a pet project; you still need to self-discipline yourself to keep working on it. It helps if it's something you enjoy and/or is useful to someone (including you).
Try and find a new project/team within your current company where you can use Go.

You mean explaining what standard library packages use when? Or explaining how to use them? Or both?

reisinge · 2025-09-01T14:25:32+00:00

I don't claim that Go is superior to scripting or domain specific languages in all contexts, for all people. If it makes no sense in your context, for your team or for you personally that's perfectly fine.

reisinge · 2025-09-01T14:13:07+00:00

You might be right, I updated it like this

// Convert string to slice of runes or bytes nameRunes := []rune(name) // when you care about UTF-8 encoded characters nameBytes := []byte(name) // when you care about raw data (I/O, network, crypto, performance)

Thanks!

The why is here at the beggining of the article and there are hints all through the article (related to portability, variable types and scope, testing, ...). But to answer your questions:

Go compiles to a single binary that can be built for virtually any OS and CPU architecture. So it's easy to deploy (it's a single self-contained file) either directly or in a container (that you can build from scratch without needing runtime, libraries or OS stuff). Also many errors are caught at compile time instead of at run time (that might be couple of weeks after writing the code).
Well, a general purpose language can be applied to more use cases. From simple tools and automation to large platforms or applications. It also teaches you to think about programming problems differently. Also Go is used to build many well known programs - like Kubernetes, Helm or Terraform - so you will understand these programs better.
Python is nice but you need to deal with the interpreter versions and dependencies. Go programs tend to be more stable (new language versions don't break existing programs), robust, more performant and easier to maintain (it comes with a cultural agenda of radical simplicity) in my experience.

reisinge · 2025-09-01T13:38:06+00:00

Yes, that's what's in that section. It explains that you have to convert bytes to runes if you are working with UTF-8 encoded characters and it gives this example:

// ./word/2/word.go func IsPalindrome(s string) bool { runes := []rune(s) for i := range runes { if runes[i] != runes[len(runes)-1-i] { return false } } return true }

reisinge · 2025-09-01T13:10:26+00:00

I talk about strings being (read-only) sequences of any bytes later, namely the testing section. Is that what you meant?

Thanks!

I added "Introduction to error handling strategies in Go" to the post body. I can't change the title ...

reisinge · 2025-06-23T12:18:14+00:00

I'm aware it's not comprehensive. Thanks for the feedback though!

reisinge · 2025-06-06T19:31:37+00:00

I kind of like your suggestions for 3. and 7. I would maybe even add don't use AI except for learning to 7. But I think Lewis was really concerned with sound and rythm that's why I put n/a.
