Conventions:

Defining Eloquent model (will assume that DB table named is set as plural of class name and primary key named "id"):

class Shop extends Eloquent {}

Using custom table name

protected $table = 'my_shops';

GCC compiler optimization for ARM-based systems

2017-03-03 fm4dd

The gcc compiler can optimize code by taking advantage of CPU specific features. Especially for ARM CPU's, this can have impact on application performance. ARM CPU's, even under the same architecture, could be implemented with different versions of floating point units (FPU). Utilizing full FPU potential improves performance of heavier operating systems such as full Linux distributions.

-mcpu, -march: Defining the CPU type and architecture

These flags can both be used to set the CPU type. Setting one or the other is sufficient.

# DO NOT PUT THE WIFI DONGLE IN THE DEVICE BEFORE MENTIONED EXPLICITLY BELOW

# Brief note, after this the UI will not show the usb dongle, 
# the wifi does work and I get an IP address, so all works,
# but I don't go into detail of making it show on the Raspbian UI.
# (for this purpose I don't care about the UI)

# For the use of this I connected my device to an ethernet connection and through the Router could see the IP which I can SSH into.
