Money Management in Linux
Now let's pretend you just received your bank statement in the mail and you want to reconcile your new CBB account. Let's also pretend that you didn't mess things up too badly while editing transactions...
Find the Balance button near the bottom right-hand corner of the CBB window and click on it. This will bring up a list of all “uncleared” transactions.
Enter a statement ending balance of $1740.00. (Leave the statement beginning balance as $0.00.)
Select the first four transactions as well as the sixth transaction. (Pretend these were the ones that showed up on your statement.) As you select transactions, watch the “Debits = n, Credits = m, Difference = i” line.
Figure 4. Reconciled Account
When the starting balance - withdrawals + deposits = ending balance, click on the Update button to mark all the selected transactions as cleared.
Congratulations: your account should be balanced.
When your next statement arrives and you run the balance routine again, you will only be presented with “uncleared” transactions to select. This is a good way to spot old checks that never were cashed, such as the mortgage payment that was “lost in the mail”. Note: By balancing your checkbook in this manner, two good things happen. First, when your brother finally cashes that check for $100.00—many months after you wrote it—your bank balance doesn't suddenly drop $100.00 from where you think it should be. Once that transaction was entered, the amount was subtracted from your bank balance. Second, it is easy to spot these situations—you can call up your brother and pester him to cash the check.
Now that you have entered a bit of data, you may want to “understand” your data at a deeper level. CBB comes with several reports and graphs which can help you get a better idea of where and how your money is being spent. Feel free to generate and look at a few reports and graphs at this point.
Wow! You've been slaving away for the last 10 minutes perfecting your demo account. Great job! That is about all there is to it. CBB isn't rocket science. It just boils down to “plus and minus”. Since this is not real data, you probably don't care to save it. However, if this had been an actual account, you most definitely would want to save your hard work.
If you want to save the changes you have made to an account, you must tell CBB to write the changes to a file. If you forget to save your work before you quit, CBB will remind you to do this. If you do something awful, like reboot your machine or log out without saving, you are not completely out of luck. CBB periodically saves a backup copy of your account with a file name such as #account.cbb#. Just rename this file to account.cbb and you will be back on track.
If you have made it this far, chances are you will be interested in some more information. I have a section devoted to CBB on my web page. Here you can find the complete CBB manual on-line, the readme file, the CBB FAQ, and several screen shots. You can even try running a live demo of CBB.

It wouldn't be fair to end this article without mentioning two other free personal finance packages I am aware of. The first is Xfinans, another personal account manager. You can find out more about Xfinans at www.iesd.auc.dk/~lupus/xfinans.html. The second package is called Xinvest, a neat investment tracking application. Look for the source code at ftp://ftp.x.org/contrib/applications/.

Please enter your name: Curtis Olson Hello Curtis. I am thinking of a number between 1 and 100...“Ooohhh, I still get goose bumps thinking about how it remembered my name. Now, if only I could remember its name...”
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
