Single-node Kubernetes on Raspberry Pi

I’ve recently got a Raspberry Pi 4 Model B 8GB. I wanted to have one just to try running Kubernetes on Raspberry Pi. Most resources on the web seem to be for a huge cluster with a dozen nodes but I wanted to do it with a single node.

As the operating system I chose  Ubuntu because of its Pi support even though I prefer Red Hat based distros. Continue reading Single-node Kubernetes on Raspberry Pi

Cheap & durable keyboard & mouse set by Logitech

As a programmer I care about the keyboard and mouse I use whilst working. I’ve been a fan of Logitech since I was a teenager. I loved Logitech GT27 steering wheel, their mice, and keyboards which I used when I was younger. I guess I have a bit of a bias on Logitech products. Read my review to decide whether my bias shows.

I’ve been using Logitech K270 keyboard and Anywhere MX mouse for 9 years. I’ve bought the first keyboard and mouse set in 2012 (9 years before this post) and got a second pair in 2016 (5 years before this post). I use one of the pairs for home and one for the office.

PHP Dos and Don’ts aka Programmers I Don’t Like

I will find you meme - Taken (2008)I am sure every PHP developer has a colleague they hate because he/she coded the application they started maintaining. This is mostly because the code is old. New standards become common, they learn what they used to do was inefficient, unreadable, or complicated. As PHP is a language that changed significantly over the years, code written a few years ago will certainly look outdated.

That being said, this post is not about the old PHP code. This post shows how to be a bad programmer even when following standards. Please don’t be this person.

  1. Too many nested if statements
  2. Extra brackets and braces
  3. Unnecessary casting
  4. Useless checks
  5. Slow PHP built-in functions
  6. Long functions
  7. Too many function arguments
  8. Long lines
  9. Long if-else blocks
  10. Wrong function / class name casing
  11. Lack of coding standards

Too many nested if statements

This is probably the one I hate the most. It also makes the lines too long because of the indentation caused by each of the nested if statements.

UEFI and GPT Mess with Windows 10 and Linux

Operating System not found

I’ve recently bought a Dell XPS 13 9350.


I tried installing Fedora on it but the installer was not able to detect the SSD. I tried disabling UEFI and it worked. The problem was that as soon as I disabled it I was no longer able to boot into Windows 10. I tried different combinations and every change that resulted in Fedora installer seeing the drive, broke Windows 10 boot setup. I thought I would be able to enable UEFI after the setup and use Windows 10 whenever I needed it and decided to install Fedora.

WordPress Backup Script

Recently I remembered that I had this little handy script that I used to backup my WordPress blog. The script contains only 2 actual commands.

I used nice while compressing / uncompressing the files to avoid CPU throttling since my blog is running on a shared hosting server.

This WordPress backup script doesn’t work without user interaction since it needs you to enter the password. Continue reading WordPress Backup Script
