![Underclocking a Website](https://images.ctfassets.net/vzl5fkwyme3u/1gUKgVHV36U4mqgWwwIA8G/1e350cae18d63baa658ce1ce39eaf991/AdobeStock_142796620.jpeg?w=1000)

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?

Ask the underclockers, I'm totally not sure. Actually, hanging around the Web these days leaves a feeling that nearly every website out there must have been underclocked, but most of the time it's about tons of unnecessary images, megabytes of javascript (of which hardly a hundred kilobytes gets actually executed), and all that. In this post I will, however, tell you about a server-side approach to underclocking, with a help of our good old friend - the MySQL Database Server.

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...

![Happy Thanksgiving](https://images.ctfassets.net/vzl5fkwyme3u/210WuoFQk8i8YI8iAUsyuA/a31e17d34e57fd9dc83c795d1b59ac73/AdobeStock_177353492.jpeg?w=1000)

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...

![Creating a Virus with PHP](https://images.ctfassets.net/vzl5fkwyme3u/1Ake3wrxwAyQSMs0amgYmG/79bd99b12402c71afb4f2290c5962daa/virus.png?w=1000)

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.

Hey there! This reading is not going to be a technical one. Instead, it's just a little portion of information that you might have not known before. I once worked for a project that did currency exchanges. As you probably know, currencies have 3-letter codes (ISO 4217), and I asked myself if there's a currency with code "PHP".

[PHP: Philippine peso](https://en.wikipedia.org/wiki/Philippine_peso)! In Philippines you can code PHP for PHP!

![Philippine Pesos](https://upload.wikimedia.org/wikipedia/commons/e/ea/PHP_2010_New_Generation_Currency_Banknotes.jpg)

But there's more to it.. "PHP: Prvi Hrvatski Pištolj" stands for "first Croatian pistol". Next time someone tells me that it's too easy to shoot your own leg with PHP, I'll definitely agree.

![Type Arrays with Variadic Functions in PHP](https://images.ctfassets.net/vzl5fkwyme3u/6e5WrjNthmKmS6C2AAWoi0/889f4e4afe965d040b17fbe7834ad07a/AdobeStock_200448817.jpeg?w=1000)

It's a very common task to work with an array of values, each of the same type. Integers, strings, all kinds of objects etc. But PHP is still a weakly typed language, so it's hard to tell if an arbitrary array actually contains only values of a given type.

Of course, you can always use a class:

```

class IntArray {

private $values = [];

public function add(int $value) {

$this->values[] = $value;

}

}

```

Then, whenever you need an array of integers, you may write something like this:

```

class BatchProcessor

{

private $ids;

public function __construct(IntArray $ids) {

$this->ids = $ids;

}

}

```

Not bad. You'll need a class per type, though, and that may seem a bi...
