Compression Formats in Linux Shell Script

by Sarath Lakshman | January 2011 | Cookbooks Linux Servers Open Source

Taking snapshots and backups of data are regular tasks we come across. When it comes to a server or large data storage systems, regular backups are important. It is possible to automate backups via shell scripting. Archiving and compression seems to find usage in the everyday life of a system admin or a regular user. There are various compression formats that can be used in various ways so that best results can be obtained.

In this article by Sarath Lakshman, author of Linux Shell Scripting Cookbook, we will cover the following recipes:

  • Compressing with gunzip (gzip)
  • Compressing with bunzip (bzip)
  • Compressing with lzma
  • Archiving and compressing with zip
  • Heavy compression squashfs fileystem

Components - Reusing Rules, Conditions, and Actions

by Robert Varkonyi | January 2013 | Drupal Open Source

This article by Robert Varkonyi, author of Drupal Rules How-to, explains the benefits of using Components by creating a Condition that can be re-used in other rule configurations.

In this scenario, we want to perform some action when a node is being commented on. But we only want to execute the action if the node was not created by the super admin (that is, user 1) and the node is either an article, or has an image field (field_image).

Compiling and Running Handbrake in Ubuntu

by Delan Azabani | May 2010 | Linux Servers Open Source Web Graphics & Video

Handbrake is considered the Swiss Army knife of video conversion tools. Running on the three major operating system platforms, Handbrake can open a huge variety of formats, including common ones that others can't handle (like the titles in the MPEG TS structure of a DVD). Handbrake outputs to a small selection of efficient formats, including H.264/MPEG-4 AVC, MPEG-4 ASP and Theora video. It has advanced features including chapter marking, subtitle inclusion and audio selection, plus filters for optimising video. On Linux, Handbrake can make use of the libdvdcss2 library to decrypt CSS-protected DVDs in-place during encoding, saving the need to use DVD Decrypter or another tool, usually through Wine. This article by Delan Azabani will guide you through the process for building Handbrake, installing it and converting video with it.

Competitive Service and Contract Management in SAP Business ONE Implementation: Part 1

by Wolfgang Niefert | May 2009 | Architecture & Analysis

In this article by Wolfgang Niefert, we will take a closer look at the service module to evaluate potential actions that are triggered, based on service-related information. The concept introduced here will utilize the service module features to establish a guaranteed response time for customers. You will see that there are various angles to look at service. In addition to its more traditional view, service can be used to establish a service-level-type management for customers and the related sales opportunities. Basically, the service module can be used as a sophisticated alert system.

Comparing Cursor and Set Approaches in Processing Relational Data

by Djoni Darmawikarta | October 2008 | MySQL PHP

MySQL introduced cursor in its release 5. You create a cursor to define a set of rows from one or more table that you want to access row-by-row sequentially. If your need is really to access the rows one at a time then use cursor. But a lot of data processing is actually set processing, and set processing is what relational database is best for.

This article by Djoni Darmawikarta compares cursor approach and set approach using various examples.

Communicating from Dynamics CRM to BizTalk Server

by Richard Seroter | July 2011 | Enterprise Articles Microsoft

One can imagine many scenarios where Dynamics CRM either publishes data to BizTalk Server or queries BizTalk-exposed service endpoints. For instance, when a customer requests a refund for a defective product, the call center agent may record this request in Dynamics CRM. After the phone call is over, Dynamics CRM should send a message to a returns processing system which handles the crediting of a customer's account. In another scenario, BizTalk Server may be the host of a data aggregation service which queries three enterprise systems that store "customer" data and aggregates the responses. Dynamics CRM may want to execute that service when a call center agent views a customer record so that they get a fuller picture of that customer's interactions with the company.

In this article by Richard Seroter, author of Microsoft BizTalk 2010: Line of Business Systems Integration, we will see how Dynamics CRM sends data to BizTalk Server.

Common AsyncTask issues

by Steve Liles | December 2013 | Open Source

In this article by Steve Liles, the author of Asynchronous Android, we will take a look at AsyncTask which was introduced in Android at API level 3, Cupcake, with the express purpose of helping developers to avoid blocking the main thread. The Async part of the name of this class comes from the word asynchronous, which literally means not occurring at the same time. AsyncTask is an abstract class, and as such, must be subclassed for use. At the minimum, our subclass must provide an implementation for the abstract doInBackground method, which defines the work that we want to get done off the main thread.

As with any powerful programming abstraction, AsyncTask is not entirely free from issues and compromises.
