The purpose of using a Dynamic DNS service is to map your WAN (or Public) IP address to a name. A domain name is easier to remember and it is not affected if your WAN IP address changes, unless you signed up for a business account which offers static public IP address.

Dynamic DNS is a service, mostly free, and there are quite a few of them available. One option would be to just Google for one but I wanted to make sure that the service is supported by my router.

List of Dynamic DNS providers supported by my router.

I have a paid account with NoIP.com, DynDNS was a popular choice until they quit offering their free service early April 2014. I randomly settled with “ChangeIP.com”. Read full post →How to Set Up Dynamic DNS



A Static IP address is a requirement if some hardware within your network act as a “server” or a “resource”.
Every devices (computers, tablets, smartphones) connected to a network has a unique address, known as IP address. The IP address has two components, the Network ID and the Host ID. Let’s look at the most common IP address schema on a home network, Class C, 192.168.1.8.

The 16 bits Host ID allows for a maximum of 256 IDs (0 to 255) on the network. However, “0” and “255” are reserved and at least one ID is going to be used by the router, “1”. As a mini spoiler here, when assigning a static IP address, only the “Host ID” is affected. Read full post →How to Setup a Static IP address



If you are considering hosting services (web service, FTP service, game server) on your home network computers accessible from the Internet, then port forwarding is a prerequisite. Port forwarding, also called port mapping, is a networking process, NAT/PAT, to allow a remote computer, from the internet, to be redirected to a port listening on a private network where a service is running.

The iPhone is undoubtedly an extremely powerful handset, but one of the main weaknesses of modern devices is the lack of battery life, and the iPhone is no exception.

Depending on your familiarity with iOS and smartphones, some of these might seem like common sense, while some seem like a great new idea. As long as it helps, we’re happy. This guide is written for iOS 7, but most of it will apply to previous versions of iOS too.

The WP Super Cache plugin by Donncha O Caoimh is one of the most useful plugins available for WordPress, and it will help you keep a site functioning well and served to your users in a cost-efficient manner.

There are many WP Super Cache (or WPSC) articles that will provide you a quick explanation on how to use it. In truth, you could get by, just by activating the plugin and do nothing else – it is that good. However, if you are reading this page, I’m assuming that you want to understand more about WPSC in order to use it optimally.

My goal is to provide information that I have gathered over years of using WPSC in a production environment, serving up millions of page views per month and mostly surviving any incoming traffic onslaught that happened, including the Apple live blogs. Overall, things went well, but I’ll share a few bumps on the road, hoping that you can avoid them as your inevitable success will lead you to new levels of traffic.

youtube-music-streaming-serviceYouTube is nearly ten years old, and over this decade, it has evolved, a lot. The vast majority of popular artists first share their new creations on the video platform through their network’s account – this was unthinkable not so long ago.  There is also a wealth of home-grown bands and other artists who share their music freely on the service. Some of them are ad-supported, some don’t use advertisement at all.

Because going to YouTube is not always the most convenient way to listen to music (flying out, going camping…), I am sure that some of you wish to convert these music videos to .mp3 format, thus saving memory (vs. a video) on your phone or computer. Well, there are fortunately multiple ways to do that, and all of them are a piece of cake. Read full post →How To Convert YouTube To MP3


It’s not news that the Chrome support for high DPI (hiDPI) has been a work in progress for some time, and within the past year or so, the proliferation of high DPI displays on laptops has made the need for good high dpi support even more important. I have messed with a few beta features before, and some of them ended up making Chrome completely unusable.

I mostly tolerated the lack of high DPI on 13.3” laptop screens, but now that I work with a 32” 4K desktop display, I can no longer use Chrome without true high DPI support. Unfortunately, the old tricks won’t work anymore, but fret not there is a solution that does. Read full post →Chrome High DPI: How To Enable It In Windows 8, 8.1 (v34+)
