I frequent the Console application in OS X, and, lately, I have been noticing a lot of the following error message:

More and more devices are becoming wireless. It isn’t unheard of for one person to be carrying three or more wireless devices on them at one time: a phone, a tablet, a laptop, and, more recently, a watch.
There are plenty of benchmarks and articles detailing the throughput achieved from a wireless device to a wired device - with a wireless router in the middle of course. This is useful to know if you’re transferring or streaming data from your laptop, phone, or tablet to a device connected via ethernet. However, most people forgo connecting anything via ethernet because connecting wirelessly is just too easy. I am much more interested in the throughput achieved from one wirelessly connected device to another wirelessly connected device.

I work for Rackspace, home of Fanatical Support. What is Fanatical Support? Fanatical Support is multifaceted, but one part of it is going above and beyond the call of duty for the customer.
Few companies provide true Fanatical Support. Doxie is one of the companies that does.

Datadog is a fantastic monitoring as a service company. Install their agent on your host and within seconds metrics are uploaded to their service to begin graphing. Their service can integrate with many popular products, but I have yet to find a plugin to integrate Datadog with one of the most talked about pieces of software today: OpenStack.

With the release of the new retina MacBook, all of the major tech blogs have released their reviews. Arstechnica always digs deep into the technical bits of a new Apple product and I noticed something interesting buried in one of their pages.

In a previous post, I detailed how to setup Varnish 2.1.5 on CentOS 6 as a caching server and load balancer. After setting this up, I realized MP4 files were not streaming and large downloads were taking too long to begin.
Varnish 4 is the latest major release of Varnish and has fixed all of these problems.
This post will be exactly the same as the last post, but will provide the new VCL syntax that applies to Varnish 4.

Varnish is a highly regarded HTTP caching server. It sits in front of your web server tier and caches content in RAM so subsequent requests are served as quickly as possible.
Varnish can also be a basic load balancer. Combining a caching server and a load balancer works extremely well when one or more of your web servers becomes unavailable. Because Varnish is also acting as the load balancer, no longer will the end user possibly see a “Service unavailable” message while the load balancer is removing the unhealthy web server from the load balanced pool, they will simply see a cached paged instead.

Force Touch was first revealed in the Apple Watch and now has made its way to Apple’s trackpads. I went to an Apple Store to try out Force Touch on the updated 13” retina MacBook Pro.

I recently setup a two node replica Gluster cluster on CentOS 6.6 with Gluster version 3.6.2-1. I setup a private network specifically for Gluster replication and communication and binded the Gluster daemons to this network.
