In the news: Go on AWS Lambda
Just recently, Amazon announced support for Go on AWS Lambda. Here is a summary of last week’s news around this topic.
How to Create PDF Documents
Pure data is for computers and nerds like you and me. Anyone else likes nicely formatted reports. Go and a good PDF package can help.
Processing spreadsheet data in Go
Your managers, all through the hierarchy, love circulating spreadsheets via email. (They simply don’t know better.) How to extract and analyze the relevant data from the daily mess? Go can help.
A DIY Dashboard with Grafana
If your code creates some stats to monitor, Grafana and the Grada package may come in handy.
Go slices are not dynamic arrays
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.
goman - the missing man pages for Go binaries
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.
Controlling a Digispark board
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.
Big Oh!
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.
Text-Based User Interfaces
Want to equip your command-line application with a nice visual user interface? TUI libraries are here to help.
Flow To Go
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?
