Create Checksums Using The Luhn Algorithm In PHP

The Luhn algorithm was created by Hans Peter Luhn and is a way of creating a simple checksum for a number. This algorithm, also known as the mod 10 algorithm, is used in a wide variety of applications but is commonly associated with credit card numbers. If you look at the numbers on the front of your credit card the last digit on the right is the checksum. An algorithm is done on the other numbers and if the checksum is the same then the number is considered valid.

I had some issues with debugging reverse proxy headers this week. After not finding a module that allows me to do what I needed, I created this little module
https://www.drupal.org/project/debug_headers
It allows you to drop a block on a page and view the headers available.
Currently as a dev release, but if it looks ok I'll release it as a full module.

New! Keychron Q3 Pro SE Wireless Mechanical Keyboard: A Review

Whilst looking at the Keychron site I found the Q3 Pro, which is a TKL keyboard that has a wheel and 4 macro keys.

It has been over a year since I bought this board and I have spent many hours typing on it I thought a review was about due for it.

Keychron Q3 Pro SE Wireless Mechanical Keyboard: A Review

When I bought my Keychron K2 in 2020 I was happy with it for a couple of years before I wondered what other options were available. During that time Keychron lunched quite a few different keyboards, including updates to the K2. The K2 I have is version 1, and whilst it is a good keyboard I was looking for a keyboard with more features and hot swappable switches so I could experiment a little.

A Look At Flood Fill Algorithms In PHP

This is a mechanism by which an area of an image can be filled with a different colour and is normally depicted by a pain can pouring paint.The flood fill algorithms used to fill in spaces in images are well known, and have been used for decades in all kinds of systems, not just graphics processing programs.

From the archive! Creating A Game With PHP Part 4: Side Scrolling Shooter

This article looks at creating an ASCII based game played on the command line, in PHP.

A side scrolling shooter, if you didn't already know, moves a scene from right to left across the screen with enemies moving with the scene towards the player's ship, which is on the left hand side of the scene.

Creating A Game With PHP Part 4: Side Scrolling Shooter

As another step up from the game of snake I created in my last post I decided to try my hand at creating a side scrolling shooter. Just like my other posts, this is an ASCII based game played on the command line. A side scrolling shooter, if you didn't already know, moves a scene from right to left across the screen with enemies moving with the scene towards the player's ship, which is on the left hand side of the scene. The player can fire bullets towards the enemies so remove them from the scene.

New! A Look At Benford's Law

Benford's Law is an interesting heuristic in data analysis. It states that in any large collection of numbers that are created naturally, you should expect to see numbers starting with the number 1 about 30% of the time.

In this article we will look at how to calculate Benford's Law and then applying the law against a series of data sets to see if we can spot any issues.

A Look At Benfords Law

Benfords Law is an interesting heuristic in data analysis. It states that in any large collection of numbers that are created naturally, you should expect to see numbers starting with the number 1 about 30% of the time. The frequency distribution of numbers states that 2 should appear about 17% of the time, down to 9 being seen just 5% of the time.

Protecting A Page From Being Directly Accessed With PHP

I was thinking recently about the number of ways in which I could restrict access to a page using PHP.The obvious option is to create a user authentication system, but in some situations that is overkill for what is required. If you just want to prevent users from going directly to a certain page then there are a few options open to you.
