Now that the Thanksgiving and Black Friday are left behind, we're all back at our desks, some of us having PHPStorm open for the whole day. In this post, I'll say a few words on this [beautiful IDE](https://www.jetbrains.com/phpstorm/), [PHPUnit](https://phpunit.de/) and [XDebug](https://xdebug.org/).
**You know that unit tests are essential, don't you?** So do the PHPStorm developers. This industry-standard level IDE has tons of capabilities for integrating test frameworks and debuggers into your project. Even if you use VMs or containers to run your development environment, chances are they got you covered!

I often see even experienced PHP programmers debugging their code with `var_dump()`, which is obviously not the best way to do it. If you see the code for the first time, if you work with legacy code - step-by-step interactive debugging is the way to go. Sometimes it can s...

# What is a Daemon?
The term daemon was coined by the programmers of Project MAC at MIT. It is inspired on Maxwell's demon in charge of sorting molecules in the background. The UNIX systems adopted this terminology for daemon programs.
It also refers to a character from Greek mythology that performs the tasks for which the gods do not want to take. As stated in the "Reference System Administrator UNIX", in ancient Greece, the concept of "personal daemon" was, in part, comparable to the modern concept of "guardian angel." BSD family of operating systems use the image as a demon's logo.
Daemons are usually started at machine boot time. In the technical sense, a demon is considered a process that does not have a controlling terminal, and accordingly there is no user interface. Mo...

For those of you not familiar with the concept of underclocking: it's the opposite of overclocking, that is, you don't speed up CPU but instead slow it down..
### What for?
Today I had a nice chat in my client's development telegram channel. The two other devs, R** and V**, were making a switch of the old imag...
A brief (by Mike's standards) note
> As we express our gratitude, we must never forget that the highest appreciation is not to utter words, but to live by them. - John F. Kennedy
I wanted to take a brief moment to express my gratitude this holiday season. First and foremost, a huge thank you to the beautiful Tanja Hoefler who has put in countless hours behind the scenes of Nomad PHP, ranging from finding the best articles and tweeting them out, to tracking down great speakers, to countless hours of video editing (including fixing all my mistakes from the live broadcast).
### Thank you to our Founders
I also need to thank Cal and Kathy Evans, an amazing husband and wife team who have done so much for the community over many, many years - including founding and being an inv...

In his talk, “[Writing Viruses for Fun, Not Profit](https://beta.nomadphp.com/video/220/writing-viruses-for-fun-not-profit),” **[Ben Dechrai](https://twitter.com/bendechrai)** (after making the viewer take a pledge to only use this knowledge for good and not evil) walks through how many viruses operate, and just how easy it is to build your own self-replicating virus in PHP.
The danger of many of these viruses according to Ben is that the most dangerous viruses often escape detection by not looking like a virus. Instead they encrypt their code to hide their true intent, while also constantly adapting and evolving.
Perhaps even more dangerously, they act like they’re benign and don’t actually do anything - often times laying dormant until called upon by the malicious actor.
