If your code creates some stats to monitor, Grafana and the Grada package may come in handy.

Go’s slices are cleverly designed. They provide the look-and-feel of truly dynamic arrays while being optimized for performance. However, not being aware of the slice mechanisms can bring you into trouble.

Most Go binaries come without any man page. The tool goman fills this gap. If the corresponding project includes a decent README file (and most projects do), goman find this README file and displays it on the terminal.

The Digispark is perhaps as small as a microcontroller board for DIY electronics can get. This is a short writedown about my first experiences with controlling this board through Go code, using Gobot and LittleWire.

You worked hard to save a few CPU cycles in the central loop, but your code is still slow? Time to think about the time complexity of your algorithm.

Want to equip your command-line application with a nice visual user interface? TUI libraries are here to help.

If you want to do Flow-Based Programming in Go, there are a couple of frameworks and libraries available. Or you simply do it with pure Go. After all, how difficult can it be?

In Flow-Based Programming, programs are modeled as data flowing between independent processing units. Who would not think of channels and goroutines as a natural analogy?

Connecting two processes at TCP/IP level might seem scary at first, but in Go it is easier than one might think.

Let’s face it: Pictures taken with a smartphone usually aren’t quite like Ansel Adams masterpieces. But with a little post-processing, some of them might still reveal their true beauty. A couple of Go libraries can help.
