How to call go from c with string (char *) as the parameter without making a copy

Here is the gist for showing how to send string from c to go without a copy, for sending an float32 array from c to go without copy, please see here

Below is the documentation for converting between a c string and a go string:

// From https://golang.org/cmd/cgo/
// A few special functions convert between Go and C types by making copies of the data. 
// Go string to C string
// The C string is allocated in the C heap using malloc.
// It is the caller's responsibility to arrange for it to be
// freed, such as by calling C.free (be sure to include stdlib.h

Enabling wifi on Ubuntu server 18

Wifi on Ubuntu 18 server

TLDR

  1. Install wpasupplicant
  2. Turn on wifi radios: sudo nmcli radio wifi on
  3. Check your devices are recognised even if they're not "managed": sudo iwconfig
  4. Check your wifi (here called "wlp3s0") is capable of detecting nearby routers: sudo iwlist wlp3s0 scan
  5. Configure netplan by dropping a file called 01-netcfg.yaml into /etc/netplan/ or edit existing file there. See example below.
  6. netplan try, netplan generate, netplan apply.
