Using memcached to Cache Content

Web servers in the modern era are expected to do a great deal of processing and serving of all different types of content; the amount and type of content now, in fact, is far greater and more varied than it was even ten years ago. In response to these demands placed on web servers and database servers, caching systems have come into existence in order to speed up performance and help with database and web performance. memcached is a distributed memory caching system developed for use in LiveJournal’s web and database service. It is now a general-purpose, open caching server for… View full post »

Hadoop can be a very powerful resource, if used correctly; it’s a system designed to work with a vast amount of data while simultaneously taking advantage of the hardware it’s using, low-end or not. It can be a bit difficult to set up, however; as a result, many people don’t take advantage of the system. Let’s take a look at how to set up your first single-node cluster to give you a look at how Hadoop can help your business!

Installing Android NDK

What is Android NDK? Chances are, if you’ve found this article, you know already what the Android NDK is. If you’ve stumbled upon here by chance, however, here’s a quick explanation: The Android NDK is a set of tools provided by Google to allow Android developers to code portions of their applications in native C, which then gets compiled into the application to run just the same as any other Android application. The advantage to this is that there is a performance increase for some processes with native code (though not automatically) and some developers can harness it to see performance… View full post »

Amazon Associates Affiliate Alternatives

For those Amazon affiliates living in California, a rather crushing blow has been dealt recently by California’s government. A new bill, ABX1 28, has forced all online retailers with a physical presence in the state of California to pay taxes in the state of California, and this bill rules that affiliates, such as the ones in Amazon’s affiliate program, count as a physical presence. In response, Amazon shuttered its affiliate program practically overnight and left some 25000+ affiliates floundering for a way to supplement their affiliate income. Like many California webmasters out there, we’ve had a few articles on our… View full post »

Android Malware: Should You Be Concerned?

There have been, recently, a fair number of apps pulled from the Android market because they were, in fact, malware; they would dial pay numbers and do other shady things, including stealing contacts. Though Google has since pulled these apps from the market, the lingering, uncomfortable question remains: Should we be worried about Android malware? The question is difficult to answer because of the layers of meaning in that question, but for the most part we can say this: though no computing platform is ever truly safe, Android users who do not stray from the official Android markets will, for the most… View full post »

PHP Tutorial: An Introduction to PDO

Since its inception, PHP has moved from a procedural language to an object-oriented one; some of its procedural roots, however, still linger. One of these procedural remnants is an antique method of accessing SQL databases; many programmers still use the older mysql and postgresql procedural modules to access databases, and even those who have switched to newer methods, like mysqli, might still be hampered by the fact that such a module only works with mysqli. PHP has since implemented better methods, but many procedural PHP developers are unsure of how to use newer, object-oriented MySQL connection methods. Let’s delve… View full post »
