Install and configure HA Proxy on Ubuntu

2nd Dec 2021 John Comments 0 Comment

Installing the latest HA Proxy You could use sudo apt-get install haproxy, but the version in the repo is likely not the latest stable release. To get the latest stable release, check on the HA Proxy site which is the latest. At the time of this writing it was 2.5. You can use PPA (personal package archive) on Ubuntu to get the latest version: sudo apt install –no-install-recommends software-properties-common sudo add-apt-repository ppa:vbernat/haproxy-2.5 -y sudo apt install haproxy=2.5.\* Adding =2.5.\* to the end…

How to check your paypal account age

5th Nov 2020 John Comments 0 Comment

Paypal have done a decent job of hiding your own info from you. You may want to know when you opened your paypal account (as I recently did as part of a vetting process). The info seemed to be well and truly “not there”. Fortunately I stumbled across a link, which I am keeping here for future reference: https://www.paypal.com/businessprofile/settings/info

Location API

27th Jan 2020 John Comments 0 Comment

Its been a really really busy few months and the blog posts have been slow. This one is more of a documentation to myself, but the new location API may be useful to you, and you may have additional sources of data! The idea is simple. How many times have you needed an API you can call to get the states (provinces) in a country? How many times have you needed to drill down to counties? Cities? Postal codes? This…

Auto Loading in PHP

18th Jul 2018 John Comments 0 Comment

Auto loading in PHP is the means by which to load classes (and traits and things!) without needing to specifically require the class file. On smaller projects with one or two classes and a handful of files this might not seem like a big deal, but on larger project, particularly with classes from different vendors, and in frameworks like Laravel, auto loading becomes particularly important. Our file structure To follow this PHP autoloading tutorial you should be aware of our…

Using Composer Dependency Manager

22nd Jun 2018 John Comments 1 comment

In days gone by when you wrote a project in PHP you would often write all parts of the project yourself, or you probably had code components from previous projects that you copy and pasted into your new project. You may even have gotten a third party library from the web. Of course in these days gone by you also had to figure out how to load the code into your new project. Composer Dependency Manager came along and changed…

PHP Traits

2nd Jun 2018 John Comments 0 Comment

What are PHP traits? In genetics, traits refer to a characteristic or an attribute in your DNA. For instance, you have a trait for eye colour, or hair type. In PHP traits refer to a set of common functions which can be used by multiple classes. I think of it almost as “includes for classes” (don’t quote me on that, its just a conceptual way of looking at it). As with most programming languages, PHP is easiest learned by example,…

Dependency Injection

12th May 2018 John Comments 0 Comment

Dependency injection is a design pattern which allows you to inject your dependencies into a class, rather than have them loaded from within that class. This blog post on PHP dependency injection will be an example based post without too much commentary from me. Typically when we write our classes they require functionality from other classes. One way of achieving this is to include and load a new instance of the dependency within our class. Another possibility is that…

Zend Opcache improves page load speed

9th May 2018 John Comments 2 comments

Zend Opcache in PHP improves your page speed by compiling code into machine code and storing the byte code in RAM. With each subsequent hit to a resource code is served from memory rather than being compiled again. PHP is an interpreted language. What this means is that unlike languages like C / C++, PHP is not compiled once to machine code and then executed from the binary each time. With PHP, each time a page is viewed on your…
