Book Excerpt: JDS Instant Messenger (IM)
Instant messaging, sometimes called chat, has moved from primarily a teenager's social medium to an important communication tool for professionals. It complements email and traditional tools such as the telephone, in many collaborative settings. One key benefit of instant messaging in a business context is the speed and immediacy it offers for making contact and exchanging information through the desktop, at no cost.
Many different forms of instant messaging are offered by large Internet providers and other services. Luckily, the instant messaging tool in JDS supports many of them. JDS's Instant Messenger is based on gaim, a multiprotocol Internet chat client. Instant Messenger is located in JDS under Launch > Applications > Internet > Instant Messenger.
Through JDS's Instant Messenger, you can chat with members of any of the following instant messaging and chat networks:
AOL Instant Messenger ("AIM")
Chat services or protocols not supported by JDS include:
Previously, software limited instant messaging participants to communicate only with members of their own network, where they shared the same communication protocol. For example, only a short time ago, AIM members could chat only with other AIM members but not Jabber members. Now programs such as JDS's Instant Messenger are solving the fragmentation of the instant messaging networks.
With Instant Messenger, you can maintain accounts with multiple instant messaging networks and change instant messaging services as you chat with different buddies, or even run chat sessions from different networks simultaneously. It's still impossible, however, to hold a single multiperson chat session with people across different chat networks, because the instant messaging services still use different protocols.
If you absolutely must chat with members of certain chat networks that are unsupported by JDS's Instant Messenger, you may be able to solve the problem by downloading additional software. JBuddy Messenger is another multiprotocol chat client that works with several IM networks, not covered by JDS's Instant Messenger, including AIM, ICQ, JBuddy, Lotus Sametime, MSN, and Yahoo!.
Here we cover the procedures necessary to set up your Instant Messenger account.
Sign up a new account, get a screen name
To use Instant Messenger, first you need to have a Screen Name or sign up to create a new account and Screen Name with one of the above-mentioned instant messaging networks. Table 1 tells you where to go to set up your account and Screen Name among the various networks. Take your pick.
Table 1. Where to Go to Set Up Your Account
|Chat network||Sign up for a screen name|
|AOL Instant Messenger (AIM)||my.screenname.aol.com|
|Netscape/AIM||If you already have an @netscape.net email address, your existing Netscape email USER ID and PASSWORD functions as your IM Screen Name and Password.|
Technically oriented users may enjoy reading up on the different instant messaging protocols available, since the services and functionality that each one offers varies. Each of the web sites for the instant messaging services provides useful information on its respective network, protocol, and features. There is also a useful (although incomplete) survey of the different instant messaging and chat protocols on the gaim software developers' web site.
Go to the Screen Name registration page of your chosen chat network and follow the procedure there for establishing a Screen Name and Password. Typically, you are asked to provide an email address and possibly additional information such as your birth date.
Once you have established your Screen Name, you can set up your account in Instant Messenger and begin chatting.
To set up your first chat account, open the JDS Instant Messenger program via Launch > Applications > Internet > Instant Messenger. The Login window appears. Enter your Screen Name and Password in the respective fields. (See Figure 1.)
In the Screen Name field, the phrase "<New User>" indicates that you have no Instant Messenger accounts set up yet. Highlight the phrase and press the Delete key or just type your Screen Name over it while it's highlighted. Then press the Tab key, enter your Password, and click the "Sign on" button. This immediately opens the Buddy List window on your desktop, and you are ready to chat. This also establishes your default Instant Messenger account, which the program remembers the next time you open the program. (See Figure 2.)
Users sometimes have difficulty logging in if they do not adhere to the upper- or lowercase pattern originally established in their Screen Name or Password. Your chosen chat network determines whether your Screen Names and Passwords are case-sensitive.
You can see the first (default) IM account information in Figure 3, which you automatically entered when you first performed account setup.
You may have additional different instant messenger accounts and Screen Names by which others know you on a different chat network. To add one or more of such accounts to your JDS Instant Messenger program, go to the open Buddy List window (this window is always open and on your desktop when you start Instant Messenger) and select Tools > Accounts, which opens the Accounts window. Here you can add additional IM accounts, as necessary.
Practical Task Scheduling Deployment

One of the best things about the UNIX environment (aside from being stable and efficient) is the vast array of software tools available to help you do your job. Traditionally, a UNIX tool does only one thing, but does that one thing very well. For example, grep is very easy to use and can search vast amounts of data quickly. The find tool can find a particular file or files based on all kinds of criteria. It's pretty easy to string these tools together to build even more powerful tools, such as a tool that finds all of the .log files in the /home directory and searches each one for a particular entry. This erector-set mentality allows UNIX system administrators to seem to always have the right tool for the job.
Cron traditionally has been considered another such a tool for job scheduling, but is it enough? This webinar considers that very question. The first part builds on a previous Geek Guide, Beyond Cron, and briefly describes how to know when it might be time to consider upgrading your job scheduling infrastructure. The second part presents an actual planning and implementation framework.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
