Welcome to the Three Dots Labs newsletter + ebook!

If you don't know Go yet, check Go in One Evening. It's tailored for experienced engineers, this fast-track approach skips basic concepts to accelerate your learning.

We also host a Discord server. It's a place to share your ideas, ask for a code review, or just discuss more challenging topics together. You can use this invite link.

This e-book isn't a useless theory. Many Go teams treat it as a guideline on how to create code:

Go With The Domain saves projects and gets people promoted. One reader went from team lead to VP of Engineering with
the impact the e-book made on his team:

Now it's in your arsenal of software techniques in a world where you can create bad code faster than ever. Many of the techniques that we show were invented decades ago and are now more relevant than ever in agent-assisted coding.

You need to practice to really learn something

The person from the e-mail above wasn't promoted just for reading an e-book. The only way to become a senior or principal engineer is applying what you read in practice.

Not everybody is lucky enough to work in a team where you have enough time and willingness to experiment with new techniques.We also know how hard it is to work on pet projects after work: First you need an idea complex enough to need those patterns. Second, you'll never have enough time to finish it.

Sounds familiar? We have something above the free content: our online, self-paced trainings. It's not a bootcamp or something for junior engineers: we won't waste your time teaching you how to write a function. We prepared real-life projects you build with us step by step, to practice advanced architecture patterns.

See what we offer on the Learn page. We run the trainings in cohorts, so they're not open all the time. You're in the newsletter, so we'll let you know when you can join thousands of engineers who learn with us.

If you have a learning budget, we have a team plan that offers access to all trainings all year round. See more on the "Team Plan" page.

Our trainings are still totally optional: the e-book, articles and our open-source projects stay free forever.

One last thing...

Before you go, one question: what's the biggest struggle in your projects right now? Hit reply and tell us. We read every response, and readers' answers help us decide what to write next.

Tomorrow you'll also get the first email of our free mini-course. After that, one article lands every Monday.

It's great to see you here!

Talk to you later,
