Go template that properly renders delimiters for a slice of structs

Posted on by rchapin

It is common to write go text/templates that range over a slice of objects to write out a list or array of items that are separated by some delimiter defined in the template.

In the case of a JSON array of objects, the cleanest output would be a , separating each object without a leading or trailing comma.

Because go template if statements are falsey in that a 0 value will evaluate to false you can write a template as → Continue reading “Go template that properly renders delimiters for a slice of structs”

Setting up software RAID on Debian with mdadm

Posted on by rchapin

Software RAID has come a long way. Unless you have some very high-rate, high-volume, I/O workloads with SLAs that will otherwise cost you money, for the most part a software RAID will perform just fine.
