Whether you only run one site, or are in charge of a whole network, Squid is an invaluable tool which improves performance immeasurably. Caching and performance optimization usually requires a lot of work on the developer's part, but Squid does all that for you. In this article we will learn to fine-tune our cache to achieve a better HIT ratio to save bandwidth and reduce the average page load time.
In this article by Kulbir Saini, author of Squid Proxy Server 3 Beginners Guide, we will take a look at the following:
- Cache peers or neighbors
- Caching the web documents in the main memory and hard disk
- Tuning Squid to enhance bandwidth savings and reduce latency
Squid proxy server enables you to cache your web content and return it quickly on subsequent requests. System administrators often struggle with delays and too much bandwidth being used, but Squid solves these problems by handling requests locally. By deploying Squid in accelerator mode, requests are handled faster than on normal web servers, thus making your site perform quicker than everyone else's!
Applying proxy servers to large networks can be a lot of work as you have to decide where to place restrictions and who to grant access. This article will provide you with some tips and tricks on Squid Proxy server to enhance the performance of your network.Read Squid Proxy Server: Tips and Tricks in full
Microsoft SQL Server Integration Services 2008 (SSIS) is a full service Extract, Transform, and Load (ETL) program tightly integrated with SQL Server 2008 with a Rapid Application Development (RAD) user interface.

Gradle is a tool for build automation. With Gradle, we can automate the compiling, testing, packaging, and deployment of our software or other types of projects. Gradle is flexible but has sensible defaults for most projects. This means we can rely on the defaults, if we don't want something special, but can still use the flexibility to adapt a build to certain custom needs.
This article by Hubert Klein Ikkink, author of Gradle Effective Implementation Guide introduces Gradle and explains how to install Gradle.
Gradle is already used by big open source projects, such as Spring, Hibernate, and Grails. Enterprise companies such as LinkedIn also use Gradle.Read Starting with Gradle in full

One trap that many web site owners fall into is spending lots of time pulling in traffic but not offering anything to encourage visitors to return. This leads to a rather self-defeating cycle where the site owner is forced to constantly promote their site to keep bringing in the same number of visitors, eating up valuable time that could be spent improving the site in other ways.
Fortunately, a little time invested during the early days of building a site can pay off very well in terms of encouraging repeat visitors. In this article by Lesley Harrison, we will:
- Learn what is meant by making a site "sticky"
- Look at ways to build conversations with visitors through comments and contact forms
- Make our visitors feel like they are part of a community with gravatars, polls, and welcome messages
- Find out how to encourage visitors to subscribe to the site, and keep them coming back
In this two-part article by Ned Riaz, Jason Edwards, and Rich Babaran, we will discuss how data is stored in IBM Cognos Planning Analyst. We will begin by defining the D-Cube and explaining the things that you need to think about before creating the D-Cube. We will discuss the importance of the order of dimensions in enforcing calculation and format priorities. We will show you how you can view the multiple slices of the cube and how you can save a selection of the cube as a separate object. We will explain how you can restructure the dimensions of the cube by adding, deleting, substituting, and reordering dimensions. We will cover some of the important functions available with the D-Cube, including global formatting, exporting, and other options that can make it easier for you to work with the program. We will illustrate how you can use data entry commands that will enable you to enter data, execute mathematical operations, or set restrictions for a cell, a range of cells, or the entire cube. Finally, we will cover Breakback—a powerful feature that allows you to cascade changes throughout the cube simply by making the change to a calculated item.Read Storing Planning Data in IBM Cognos: D-Cube (Part 1) in full
