Master Server

[mariadb]
log-bin
server_id=1
log-basename=master
#skip-networking
bind-address=192.168.1.100

• log-bin causes the server to keep a log of all changes to the databses, both data and structure, as well as how long each statement took to execute.
• The server_id is a integer 1 to 4,294,967,295.

Preparation

Versions prior to Apache v2.2.12 and OpenSSL v0.9.8j required a dedicated IP address for each certificate. With Server Name Indication (SNI) there is no need to request a new IP every time a certificate needs to be installed for a domain.

SNI can secure:

• Multiple Apache sites with a single certificate
• Multiple subdomains of a domains with multiple certificates
• Multiple domains from a single IP address

With that said, you don't have to request a dedicated IP address for sites that use SSL certificates.

Docker can be best described as a lightweight virtual machine. However, it technically is a virtual environment. Unlike products such as VirtualBox, VMWare, and Parallels that require virtual hardware (BIOS, HDDs, NICs, etc), guest operating system, drivers, libraries, binaries, and a Hypervisor, Docker only requires programs and libraries to run an application.

I use a Juniper VPN in order to connect to a remote network. Since upgrading to OS X Yosemite, I found that I could no longer connect to the VPN. Normally, I would launch the application, Network Connect; enter my credentials, and bam! With the new version of OS X, Network Connect would hang when trying to establish a connection to the remote network after enter verifying my credentials. 

Introduction

A few months ago, I had written about how to setup and monitor geofences. Since then, Google has made changes to their location APIs by removing some of the classes such as the LocationClient class. This change was announced in 2013, but Google's documentation had made no mention of the changes that were to come. At the time of writing, documentation and examples on how to setup and monitor geofences using the new method are scarce.

Notifications are those little badges that appear at the top of your Android device's screen. Creating the notifications are pretty easy and straight forward and can be extended to provide actions opposed to a simple message notification. The application in this post is a simple application which has a single button that fires off a notification.

Back in May of this year, Google released an update to their Play Services. Up until then, it wasn't possible to use all the features of indoor maps found in Google Maps for Android. Strangely, iOS has had this feature for some time now. One of the those features was being able to manipulate the floor picker. To start using indoor maps properly, you will need to create a new project and configure it to use Google Play Services.

If you’ve been programming in one of the more popular object oriented programming languages such as C++ or Java, Objective-C may be a bit confusing at first. With Objective-C, you send objects messages opposed to calling methods. With C++ and Java, calling a method name means that, in most cases, it is bound to a section of code in the target class by the compiler. However, with Objective-C, the target of the message is resolved at runtime.

Both the NavigationDrawer and NavigationTabs are great for allowing a user to navigate your app. There are times that you may need to use them in conjunction and possible. However, you can not use the ActionBar Navigation Drawer and ActionBar Navigation Tabs together. In order to use tabs, you must implement them manually in your fagments.
