This chapter will introduce you to the most useful tools under Linux and X Windows.
These tools will help you to manage your time and money effectively while using Linux.
The programs discussed in this chapter are freely available on the Internet, just
as Linux is. Of course, when it comes to managing money, it's important to remember
that none of these programs gives you any warranty of any sort. You must assume all
risk when you use the software.
Linux provides great tools for doing UNIX clone programming. I have been very
impressed by Linux, and I use it a lot. When Linux first came out, however, it lacked
a lot of the personal software I relied on heavily to carry out my daily tasks. For
example, it had no checkbook management software and nothing to track my time with.
Now all that has changed. I don't boot into DOS to track the daily events and hours
spent on projects when I need to; I use titrax instead. The CBB program is not yet
mature enough to beat Quicken (from Intuit), but it's powerful enough to read Quicken
files if I need to look up something without booting into DOS.
This chapter will introduce you to the available programs. These are the programs
presented in this chapter:
- The Time Tracker, for tracking your time while you are working on the computer
- XPostit, for putting up yellow sticky notes
- CBB, for balancing your checkbook
- Xinvest, for tracking your investments
Let's get started.
The Time Tracker is a great utility for tracking your time, especially if you
are working on more than one project at a time. The program is available from the
FTP site at ftp.x.org in the /contrib/office subdirectory. The
program comes with all the source code and can be installed and built quite painlessly
on Linux. The latest version of the file was named titrax-1.98.tar.gz at
the time of writing.
Unzip and untar the file in a readable directory with this command:
$ gzip -dc titrax-1.98.tar.gz | tar -xvf -
Then edit the Imakefile to set it for use with Linux. Take these steps:
- 1. Change the value of the NONXBINDIR variable to the location
where Perl is stored on your machine. This variable's value should be set to /usr/bin
or /usr/local/bin, depending on where Perl is executed.
2. Uncomment the line with the following preprocessor directive:
-DDO_NOT_TELL_ABOUT_ME
- If you do not uncomment this line, the titrax executable attempts to ping the
author's machine. This tells him you are using the software! It's up to you to comment
or uncomment this line. With my connection to the Internet, I chose to uncomment
this line and not add to the already-burdened traffic on our local network.
After the program is up and running, you can run make install
to install it permanently on your machine. If you like, you can run it in the directory
you just made, to get a feel for the program. The initial window that is displayed
when the program is started can be resized. A resized version is shown in Figure
68.1. Three projects are listed here that I happen to be working on: Sockets, ActiveX,
and Linux 3. When I start working on a particular project, I simply click on the
line and select the name of the project. The timer then updates the value of time
for that project.

Adding a project is easy. Click the Add button to bring up a new dialog box, as shown
in Figure 68.2. Try clicking the Edit button to edit the time and headings for a
project, as shown in Figure 68.3.

The titrax program is a simple but very handy tool for managing your time. It works
only in interactive mode and does not generate reports. So even though it does not
have the fancy features of a full-blown time manager, it can still serve adequately
for personal use.
The term "Post-it" is a trademark of 3M Corporation, and the authors
of the XPostit program and 3M Corporation do not necessarily have any relationship
with each other. The XPostit program allows you to clutter your desktop with facsimiles
of those lovable yellow sticky notes as reminders. The xpostit+ binary program
is the executable application for this package. The package was written by David
Curry.
You can get the source for xpostit+, XPostitPlug-2.3.tar.gz, from ftp.x.org
in the contrib/office subdirectory. After you unzip and untar the distribution
file, you will have a new directory called XPostitPlus-2.3. Go to this directory
and run the following commands:
$ xmkmf
$ make
After the make file completes, you will have a binary file called xpostit+
in your directory. Run this file in the background as
$ xpostit+ &
You then see a screen like the one shown in Figure 68.4. Press the right button
on the plaid background, and you are presented with a list of options. Select to
create the 1.5x2 note. You are presented with a window with a yellow background.
Type in the yellow area, and you have a yellow sticky note on your window manager,
as shown in Figure 68.5.

FIGURE
68.5. A simple yellow sticky note.
Several sizes of notes are available for use with the program. The biggest size,
the 4x6 note, is a bit cumbersome to use as a sticky note.
Notes can be anchored, that is, placed at a known location on the screen. By selecting
the Cascading option, you can cause notes scattered on your desktop to be cascaded
around an anchored note.
You can set alarms for the sticky notes as well. Alarms are set for date and time
of day. The menu option Set Alarm... presents the alarm setup dialog box, shown in
Figure 68.6. Set the month, day of the month, and time for the alarm, and then click
the Accept key. When an alarm is set, a small iconic clock is displayed in the menu
of the item. You can either wait for the alarm or unset it with the Unset Alarm...
command from the menu of a note. See Figure 68.7 for a note with an alarm.

an alarm.
The text for all notes can be saved with the Save All Notes item from the menu in
the main item window. The information in each window is saved in a file in the .postitnotes
subdirectory in your home directory. Each note's data is stored in a file, with the
name of the title bar displayed on-screen. My notes are placed in files called note1,
note2, note3, and so on.
The contents of a note can be exported to other text files or even e-mailed to
someone else. Choose the Export item from the File menu, and select the file from
the list that is presented. To e-mail the contents of a note, choose e-mail
and type the address of the recipient.
The program is a simple one but with very powerful features. XPostit's simplicity
is what makes it so easy to use. Also, as with most Linux code, I can take the note
files on a floppy disk and use them on a Sun workstation with the same application.
I find the notes application a very useful tool indeed.
The CBB program is a handy utility for managing your daily checkbook. It's available
from the site ftp.me.umn.edu in the pub/finance directory. The
version number at the time of writing was 0.67, and the archive file was called cbb-0.67.tar.gz.
The program is surprisingly powerful and quite handy to use on Linux systems.
You can create accounts with CBB, manage several categories in these accounts,
do some tax-return calculations, and even import and export data using Intuit's QIF
format to programs such as Intuit's Quicken. Of course, CBB is not anything like
Quicken, and we cannot expect a freeware program to compete with a giant like Intuit's
primary product. (Yes, Linux has surprised a few giants already!) Using CBB keeps
me from booting into Messy Windoze just to enter a few transactions into Quicken,
so CBB has been well worth the install.
After you have CBB untarred and installed on your system, type make install
and answer the questions. On a Linux system, you should not have any problems. To
run the application, type cbb at the command-line prompt.
The first course of action is to create a new account. Choose the option from
the menu, and you are presented with the dialog box shown in Figure 68.8. Enter all
the information in the dialog box carefully, because it's not apparent where you
can go to edit the account information after you have entered it once.
FIGURE
68.8. Creating a new account.
The transactions are entered in the lower part of the screen, where all the boxes
are shown on the bottom of the window. You have to be careful to size the window
appropriately, or the boxes will not be visible. The main window does not resize
itself to fit the buttons on the lower portion of the window.
Any transactions for that account are shown in the main window. After you have
a new account, you can enter all your transactions for that account into it by using
the entry boxes at the bottom of the screen. As you enter transactions, you are presented
with the screen shown in Figure 68.9. Categories can be marked as tax-related for
reports to be generated at tax time. See Figures 68.10 and 68.11 for the dialog boxes
you see as you add categories.
FIGURE

68.10. Inquiry about categories.
FIGURE
68.11. Creating categories.
Amounts in a transaction can be split across several categories. The Alt-S key combination
on a transaction presents a menu, as shown in Figure 68.12. Categories must be typed
by name, and there is no option to search for a category name. If a typed name does
not exist, you are presented with the dialog shown in Figure 68.11.
FIGURE
68.12. Splitting amounts across categories.
At the end of the month, you would probably want to reconcile your bank statement
with what's in your database. You can elect to reconcile the bank statement with
the dialog box shown in Figure 68.13. Double-click on each transaction to toggle
its cleared status. The amounts of debits and credits are shown at the top of the
dialog box.
In the example shown in this chapter, we created our own transactions. Another
option is to open the demo account as provided in the demo subdirectory
for the distribution. After you are comfortable with the package, you can use it
with Quicken's QIF files. You can also use the report- and chart-generation features.
At the moment, I have limited the use of this program to only entering transactions
as they occur. For extensive reports and charts, I still use Quicken because it is
more powerful; however, the time between reboots has been reduced quite a bit since
I installed CBB.

After you have amassed your fortune and tracked it in CBB, you would probably want
to invest it somewhere. This is where Xinvest comes in, providing features where
CBB falls short.
The Xinvest tool is written to manage stock portfolios on your Linux machine.
The latest version at the time of writing, version 2.1, is available as a zipped
tar file. You can get Xinvest from the ftp.x.org site in the contrib/applications
directory. This directory contains two archives: xinvest-2.1.tar.gz with
the source files and xinvest-2.1.bin.tar.gz with precompiled binaries. Use
the binary version, because the source tree did not compile cleanly even under Slackware
Linux 2.0. The binary files compiled cleanly.
By using Xinvest, you can keep your records in separate account files. The program
lets you calculate total and annualized returns, including the effects of dividends,
buys, and sell orders. The program also lets you compare the collective value of
several accounts in a portfolio.
You can set up accounts based on category and risk and view the distribution of
wealth in each account to get a clear picture of how your funds are distributed.
The parameters for each transaction include price of share, amount of shares brought
or sold, total value of the transaction at the price of share(s), any dividends,
moving averages, cumulative averages, and both internal and total returns. You can
even plot charts of transactions over time.
The initial screen looks like the one shown in Figure 68.14. The figure shows
the directories for the sample data files and directories in the package. You can
open the files in the demo directory by double-clicking on the sample icon.
Use the INTC stock symbol as the sample portfolio's stock section. The data is
shown in the text display as it's shown in the data file. The sample data file looks
like the one shown in Listing 68.1. This is the way you would have to store your
own data files when you collect your own data. The data shown in Listing 68.1 is
used to generate the plots and graphs shown in Figures 68.15, 68.16, and 68.17. In
each of the graphs, you can pick and choose which type of chart and information you
want.
