Modularisierung von Web Applikationen

Einleitung

Ziel des Dokuments ist es, mögliche Wege zur Trennung von Daten und Geschäftslogik aufzuzeigen und diese anhand von praktischen Beispielen zu untermauern. Desweiteren sollen Konventionen und Best Practices die Teamarbeit verbessern, die Produktivtät erhöhen und die Einarbeitungszeit reduzieren.

Folgende Fragen sollten beantwortet werden:

Wann und wo trennen wir was wie und warum. (Beispiele)
Wo möglich bzw. sinnvoll bitte generelle oder spezifische Aussagen für unsere CakePHP 2.x und 3.x Applikationen machen.

Emitting stream responses with Slim

What is Chunked transfer encoding?

Chunked transfer encoding is a streaming data transfer mechanism available in version 1.1 of the Hypertext Transfer Protocol (HTTP). In chunked transfer encoding, the data stream is divided into a series of non-overlapping "chunks". The chunks are sent out and received independently of one another. No knowledge of the data stream outside the currently-being-processed chunk is necessary for both the sender and the receiver at any given time.

Designing a database

Schema Naming Conventions

Tables: english, lower_snake_case and plural.
Columns: english, lower_snake_case and singular.
Don't use reserved words
Every table must contain a auto increment primary key 'id' int(11)
Foreign key names must be unique per database. Format: sourcetable_sourcefield_destinationtable_destinationfield
The name of an index should match the field name. Multiple fields can be combined with _ (underscore).

Grr this took hours to figure out. I was trying to install MJPG-streamer and running VLC command lines and all this crap but nothing worked.

First install motion:

~> sudo apt-get install motion

Then create a config file:

~> mkdir ~/.motion

~> nano ~/.motion/motion.conf

	#!/bin/bash
	if [ "$EUID" -ne 0 ]
	then echo "Please run as root"
	exit
	fi

	apt-get install pkg-config libmagickwand-dev -y
	cd /tmp
	wget https://pecl.php.net/get/imagick-3.4.0.tgz
	tar xvzf imagick-3.4.0.tgz
