In the first half of 2015 a third of all music revenue was generated by streaming services. This is according to the Recording Industry Association of America with the well-known streaming stalwarts of Spotify, YouTube and Pandora taking 33% of the tally. The British Phonographic Industry then released a figure which really underscored the roaring rise of music streaming: 11.5 billion streams in the first six months of 2015 versus the 14.8 billion for the entirety of 2014. Music streaming has become big business and it is also a fair playground for startups and entrepreneurs

Most coverage of the Internet of Things (IoT) centers around the proliferation of connected consumer gadgets – personal and home appliances such as security cameras, thermostats, smart lighting systems, health and fitness monitoring devices. But one area that’s set to feel the biggest impact of the technology is manufacturing.

System logs are some of the most important data you can keep on your dedicated server or VPS. Chances are if something is going to go wrong, it will do it when you aren’t logged in or able to look at it live. This leaves your system log files as the only way to trace the cause of the problem and, more importantly, discover how to prevent it from occurring again. One distinct shortfall with the log files, though, is that they only log what the system is doing, not how it is performing.

Gaming in the Virtual World

The idea that you can immerse yourself in a virtual world and play games as if you are completely part of the action has been around for a long, long time. Virtual Reality (VR) has, however, proved to be an elusive dream as technology failed to match the ideas (remember the Nintendo Virtual Boy in 1995?). Then along came a start-up called Oculus Rift, a company which captured the attention of pretty much everyone, including Facebook who bought it out for a hefty $2 billion in March 2014. Then the competitors began to sneak onto the scene – HTC Vive, PlayStation VR, Gooble Cardboard, and Samsung Gear VR. VR was back, and this time the technology is ready to really make that immersive, spine-chilling, toe-tingling dream into a reality.

The Real Time Messaging Protocol (RTMP) was developed by Macromedia as a method for transferring data, audio and video for their Flash technology. Macromedia were subsequently acquired by Adobe, since when the specification has been partially released enabling third parties to implement it within Adobe’s own server and client software. This has led to the technology being commonly used when streaming media for a variety of providers. In this article we’ll be looking at setting up your own media server using Nginxp-RTMP on Ubuntu 14.04.

 
One of the most common tasks to perform when using Apache to serve websites on a dedicated server or VPS is to set up virtual hosts. This is the method by which Apache is able to present different websites to users depending upon which domain name they entered into their web browser. In this article I will be explaining how to create a virtual host in Apache as installed via the default repositories in Debian/Ubuntu or CentOS/Red Hat.
