Developing a Simple Workflow within SugarCRM

by Dr Mark Alexander Bain | June 2008 | CRM MySQL Open Source PHP

Workflow is about getting the right work to the right people at the right time, repeatedly—and knowing you have done so. Workflow is human-centric. First and foremost, workflow is a human activity that is made by and for those who use it: workflow is something that can easily be handled and understood by human beings.
UK Enterprise Workflow National e-Government Project—Workflow from a Business Perspective

Well, that sounds good, but the problems start to occur when you ask people to consider workflow in their organization, and there are usually a few main issues to deal with:

  • You'll find that people are normally experts in their own fields—there are often very few people who have an overview of the whole process that you're trying to map.
  • Sections of a large organization will often have different ways of carrying out the same overall process.
  • People don't really like to be told how to do their jobs—they especially don't like to have any extra processes imposed on them for now obvious reason—well, would you?
  • Talk of 'improved utilization of resources', 'improved performance monitoring', and such like can soon alienate the staff who are going to be using the system. They'll soon start using terms such as 'Big Brother'.

How you are able to deal with these will depend on your organization and the people that are available to you. At least once you've read this article by Dr. Mark Alexander Bain, you'll know that, once you've overcome those problems, the workflow itself will be easy.

Modeling Furniture in Blender

by Allan Brito | June 2008 | Open Source Web Graphics & Video

As furniture is a key element, every item of furniture that we add to the scene increases the level of detail, and the sense of realism. We can classify furniture into two : internal and external furniture. With the first type, we have all the objects that populate our interior scenes such as sofas, beds, and chairs. The second type refers to items of urban furniture such as cars, fountains, and fences. This kind of modeling deals with smaller scales, and because of this, sometimes, we have to work at a more detailed level than we are used to. This can cause the modeling process to take a bit longer than usual, but only if we need to create a good level of detail for our models. In this type of modeling, we will use the concept of level of detail again. Another interesting thing about furniture is that we can keep the models that we create to build a good library. In this article by Allan Brito,we will learn how to add previously created furniture into new projects, decreasing the time needed to fill up the scene with furniture, with a good 3D models library. We even can download or buy models on the Internet. The only thing that we will have to do in this case is import the model into our scene.

Development with Pluggable Authentication Modules (PAM)

by Kenneth Geisshirt | June 2008 | Linux Servers Networking & Telephony

The primary focus of Pluggable Authentication Module (PAM) is to authenticate your users. PAM lets you set up the environment that the users will work in. And when the users log out, PAM tears down the working environment in a controlled way. PAM and PAM-aware applications reduce the complexity of authentication. Application programmers can take advantage of PAM, rather than developing a complete set of authentication functions. In this article by Kenneth Geisshirt, we will see how an application uses PAM for authentication and how to develop our own PAM modules.

Data Processing using Derived Column and Aggregate Data Transformations

by Jayaram Krishnaswamy | June 2008 | .NET Microsoft

SQL Server Integration Services, using its designer interface, or BIDS, has made it possible to process data using many of the data flow related items in its Toolbox without writing a line of code. This is a very attractive option for someone who is a beginner with some knowledge of databases, and for end users who may want to look up some detail buried in the data. This tutorial by Dr. Jayaram Krishnaswamy shows how the designed package extracts data from an SQL Server 2005 and processes it using several of its built-in transformations.

Using Asterisk as a PSTN Gateway for OpenSER

by Flavio E. Goncalves | June 2008 | Linux Servers Networking & Telephony Open Source

PSTN or Public Switched Telephone Network is the collection of all the telephone networks, which are interconnected in the world. If we want to be able to route calls from and to the PSTN using OpenSER, we need to be connected to a PSTN. To send calls to the PSTN, we need a device called PSTN gateway. There are several manufacturers such as Cisco, Nortel, and others who manufacture this kind of equipment. You can also use an Asterisk PBX box for this task. Asterisk makes an affordable PSTN gateway that is very competitive with the big players mentioned above. In this article by Flavio E. Goncalves, we will see how to use asterisk as a PSTN gateway for OpenSER.

RadRails Views

by Javier Ramírez | June 2008 | AJAX Open Source Web Development

When developing a Rails project, there are more things to do than the source code itself. We have to start, stop, and monitor our servers, generate code templates, run our test suites, install plug-ins and gems, generate documentation, keep control of to-do items, or run Rake tasks for different purposes—database migrations, for example. RadRails provides different Views for supporting these tasks that are a part of the development but not of the coding itself. And, of course, it does it so we can control everything from within the IDE without having to go back to the command-line interface. In this article by Javier Ramírez, we will see how to open a View. We will also look at the Documentation Views and the Servers View, which are available as part of the Rails default perspective, that is, you don't need to do anything special to open them.
