NumPy is the de facto standard for scientific computing in Python. It extends Python with a flexible multidimensional array that allows fast mathematical calculations.
NumPy works as a framework that allows coding complex operations using a concise syntax. The multidimensional array (numpy.ndarray) is internally based on C arrays: in this way the developer can easily interface NumPy with existing C and FORTRAN code. NumPy constitutes a bridge between Python and the legacy code written using those languages.
In this article, by Gabriele Lanaro, author of Python High Performance Programming, we will learn how to create and access NumPy arrays.
In the last few years a number of packages were developed to further increase the speed of NumPy. We will explore one of these packages, numexpr, that optimizes array expressions and takes advantage of multi-core architectures.Read Fast Array Operations with NumPy in full

These days, everyone has a good reason to have a website. It's not just large companies anymore. Individuals, families, and small or independent businesses all need to have one. Some individuals and small businesses don't have the financial resources to hire a website development company or a freelance web developer to create a website for them. This is where WordPress comes in very handy. WordPress is an open source web software application that you can use to create and maintain an online website, even if you have a minimum of technical expertise.
Since it is a web application, WordPress does not need to be installed on your home computer. It can live on the server (a kind of computer) that belongs to your website hosting company. It is also free, easy to use, and packed with excellent features. Originally, WordPress was an application meant to run a blog website, but it has now evolved into a fully-featured Content Management System (CMS). In this article we will cover some of the most frequently asked questions on WordPress 3.Read FAQs on WordPress 3 in full
The term High Availability means that the servers or systems that host or run the business-critical applications should be highly available - 24 X 7 and 99.99% up time. As the word itself defines how important it is to make these applications and data available for end-users as well as business users, if this data is not available for a short time, it will be a big problem for both sets of users. Imagine a bank spread across the country and having a huge customer base faces a situation when, their server crashes! If the bank relies only on backups, then it might end up losing approximately 15 to 30 minutes of data, depending on the backup strategy. Now the HA options related to SQL Server such as Clustering, Replication, Log Shipping, and Database Mirroring will help overcome this situation.
In this article, we will find answers to the frequently asked questions on Microsoft SQL Server 2008 High Availability.Read FAQs on Microsoft SQL Server 2008 High Availability in full
