Closures in #Golang #100DaysOfCode

I just updated some of the information on the companies hiring that use #golang sheet based on feedback. If you already signed up, you have access to the updated information. If not, you can sign up to get it free here: bytesizego.com/golang-jobs

clickbait: the defer statement in Go actually has 3 types: open-coded defer, heap-allocated defer, and stack-allocated. source: victoriametrics.com/blog/defer-in-…

Many Go concurrency books and tutorials are like: here's goroutine, here's channel, here's select — use them as you like. Others just throw concurrent patterns at you without really explaining them. This is not very helpful: the most important thing in concurrent programming is not pure knowledge, but the understanding and ability to apply concurrency primitives. That's why I've created an interactive book that teaches Go concurrency from the ground up, with an emphasis on practical application. I'll be releasing it chapter by chapter over the next few months, so stay tuned!

@_jhohannes Cfbr is “Commenting for better reach” in short😅

@he3torBarbossa What's that?!

Recruiters here!!! I am open for any software engineering remote role. Please help reach out to my recruiter wai 🙏🏾😉😊

I know $12 USD is a lot of money for some people, so to celebrate 1000+ sales (!!!!), I'm giving away 1000 PDF copies of How Git Works (honour system: only if $12 is a lot for you!) Here's the link, enter code BUYONEGIVEONE at checkout to get a free copy wizardzines.com/zines/git/ (it'll ask you for a billing address but you can enter a fake address if you'd prefer)

(Retweets hugely appreciated) Today I'm proud to announce the launch of my first self-published book Foundations of Debugging for Golang Being able to debug locally and in production is a critical skill for any #golang engineer, but it is rarely taught explicitly. It has taken me many years of working with Go in production to get comfortable debugging, and I want to accelerate your learning by teaching you everything I wish I had known when I started out. What You'll Learn 👉 How to get better at spotting issues by eye. 👉 Logging patterns and how to build an enterprise logging strategy. 👉 What are metrics, how to create them and how to build great dashboards. 👉 What distributed tracing is, and how to set it up in your company. 👉 How to use Go's profiling tools to debug performance issues use and squeeze every ounce of performance out of your application. For this week only, you can get $10 off using this link: bytesizego.com/the-ultimate-g… I can't wait to hear what you think :)
