Nope.

Building blocks for idiomatic Go pipelines Unopinionated and composable channel operations.

I think third-party Go concurrency packages are often too opinionated and try to hide too much complexity.

That's why I created `chans`: a package with generic channel operations that's unopinionated, composable, and doesn't take control away from the developer.

GitHub - nalgeon/azor: Promises and async/await in Go Promises and async/await in Go. Contribute to nalgeon/azor development by creating an account on GitHub.

All jokes aside, I've implemented promises and async/await in Go. Just make sure you NEVER use them.

Gist of Go: Signaling Sending events between goroutines.

The new chapter of my interactive Go Concurrency book covers signaling, one-time execution, and object pools.

If you think channels are the only way for goroutines to communicate, check it out!

Thanks James, glad you like it!

Go features by version Which major features appeared in which versions of Go.

I've updated the list of Go features by version.

Now, each feature has ➀ a link to the documentation, ➁ a link to the proposal, and ➂ a link to the commits.

It's fascinating to see how Go has changed over the years.

On deep modules Make smaller interfaces. Seriously.

GitHub - nalgeon/redka: Redis re-implemented with SQL Redis re-implemented with SQL. Contribute to nalgeon/redka development by creating an account on GitHub.

Okay, I did it again. I reimplemented Redis using Postgres.

Key/value, expiration, maps, lists, sets, and sorted sets — everything in your favorite database. With a Redis-compatible API and wire protocol.

GitHub - nalgeon/be: Minimal test assertions in Go Minimal test assertions in Go. Contribute to nalgeon/be development by creating an account on GitHub.

How about a micro test assertions Go package with flexible error checking?

Only 100 loc. I've named it "be" :)

Gist of Go: Semaphores Limiting the concurrency and waiting for the peers.

The new chapter in my interactive Go Concurrency book is about Semaphores.

You'll have a Rendezvous with some helpful synchronization tools and even overcome a few Barriers.

If you know what I mean 😉

Redis playground Embeddable Redis playground for education, documentation, and fun.

Given how much I love Redis, it's strange that I haven't made a playground for it — until today.

Now I (and everyone else) can finally write interactive Redis docs!

Go 1.25 interactive tour Fake clock, new GC, flight recorder and more.

Go 1.25 is coming soon, and the official release notes are pretty dry.

So I prepared an interactive version with lots of examples.

antonz.org/go-1-25

Thanks, Arman! They take a lot of time to make, so I'm really glad you read them :)

It's considered experimental, so it requires a feature flag, and the API might change. But it's already pretty usable!

JSON evolution in Go: from v1 to v2 Reviewing the key changes in json/v2.

I'm working on an interactive Go 1.25 tour, but there are so many changes in json/v2 that I decided to cover them in a separate blog post.

Plenty of interactive examples ahead!

Gist of Go: Race conditions Keep the system state correct by any means necessary.

Using mutexes to avoid data races might seem simple, but dealing with race conditions is a whole other matter. Let's learn how to handle these beasts — in the new chapter of my Go Concurrency book!

antonz.org/go-concurren...

Gist of Go: Data races Two goroutines racing for the same data is a recipe for disaster.

I'm back to working on the Go Concurrency book! The new chapter is all about data races and how to avoid them: antonz.org/go-concurren...

AI-free writing I never use AI-generated content in my writing, and I never will.

Sad story of http.DefaultTransport A tale of false flexibility and leaking abstractions.

If you're into Go, I have a sad story for you. It's a tale of false flexibility, leaking abstractions, and http . DefaultTransport.

Thank you! I wonder how many of these URLs are out there :)

Thanks!

Am I online? Checking internet connectivity with 'generate 204' endpoints.

Recently, I was working on an application that needed to know if it was connected to the internet.

I didn't want to use ping (ICMP), and wanted to exercise the full stack used by real HTTP clients: DNS, TCP, and HTTP.

So I did some digging, and here are the results: antonz.org/is-online/

SQLite Extension Hub Easily find and manage SQLite extensions.

See the full list of extensions (known to me) in the extension hub: sqlpkg.org

Did you know that there are SQLite extensions for:

— Creating pivot tables.
— Storing tables in S3.
— Querying Excel files.
— Reading Protobuf messages.
— Fuzzy string matching.

And many, many others!

Graft is an open-source transactional storage engine optimized for lazy, partial, and strongly consistent replication—perfect for edge, offline-first, and distributed applications. - orbitinghail/g...

See the details at github.com/orbitinghail...

You can even install Graft using the SQLite package manager:

sqlpkg install orbitinghail/graft

Graft by @f0a.org implements strongly consistent replication between SQLite and object storage like S3/R2.

Implemented as a SQLite virtual file system. Interesting!

Thanks man :)

Grep by example: Interactive guide Interactive introduction to grep with real-world use cases.

Grep is one of the most useful cli tools I use every day.

If you use it often, I encourage you to take a look at the interactive mini-book I wrote — you might learn a thing or two even if you are an experienced grep user.
