My main hobby is playing the card game Bridge. I am a certified ACBL bridge instructor and am happy to play with anyone including beginners. Someday I hope to start an HCC Bridge Club, and perhaps someday we can compete in the inter-collegiate league. Stop by and talk bidding with me!
The American Contract Bridge League (ACBL) is one of the largest bridge organizations around. Check out their tournament schedule, tips, books, discussions, etc.
The Tampa Bay Bridge Club has home-style games plus duplicate bridge games every day. Experienced teachers provide individual or group lessons for all levels of players. Phone: (813) 935-0974.
One of the best bridge magazines in the world is The Bridge World. Their web site has contests and information for players of all levels.
The Internet Netnews group rec.games.bridge is a lively discussion group where players of all levels can ask questions or give opinions.
You can register with the Data & Marketing Association (formerly, the Direct Marketing Association) to remove yourself from many email, phone, and direct mail marketing lists by visiting www.dmachoice.org.
The U.S. government supports a Do Not Call Registry. It is a crime to make sales or marketing calls to someone listed here.
There is excellent (and very popular) free software available to provide encryption and digital signatures for your email and files, known as Gnu Privacy Guard (or GnuPG or simply GPG). This is compatible with the older Pretty Good Privacy (PGP) software. Find out more about GPG at www.gnupg.org.
You can download my GPG Public Key if you want to send me private email, or verify my digital signature. Below is what you should see if you check the fingerprint for this key:

Digital IDs — The driver's licenses for the information superhighway
StartSSL.com, Letâ€™s Encrypt, Thawte, Inc., and VeriSign, Inc. are some of the best certificate authorities (or CAs) in business. They provide digital IDs for websites, mail servers, and people, which are very hard to forge. For a small annual fee, CAs provide an X.509 personal certificate which you can load into a web browser, which like any ID card certifies that you are you to the remote web server. With a certificate installed in your email client, you can easily send and receive email that is digitally signed, encrypted, or both. You can also use certificates to digitally sign Java applets and other software, so they can access files and resources on your computer. A server certificate signed by a valid CA, is needed by a website to allow users to use TLS encryption (HTTPS protocol) when connecting to your site.
From a CA's homepage you can find (and download into your
browser) anyone's digital ID (such as mine!) and then send that
person private email.
Note that some CAs provide some free certificates.
is a very good free SSH client that supports telnet too.
Putty also provides
psftp (PuTTY secure
copy and Putty Secure FTP) as command line tools.
If you install these you can also install a GUI wrapper for these tools
winscp, that works similarly to WS_FTP.
You can get WinSCP from

High quality email software is available at www.mozilla.org/products/thunderbird. This free email client is pretty good.
Useful Web and Internet related links:
Adobe Systems Incorporated is a company famous for high quality fonts and artwork software (Illustrator). They invented the popular PDF file format, which allows you to view files without the original application that created them. Visit their homepage to download the PDF plug-in (and viewer program).
Anti-virus and firewall software
You should run a firewall and antivirus software, all the time. There are many good and free security tools available. For example, at avg.com you can find AVG anti-virus software. A free version is available.
Microsoft releases (frequently) a malicious software removal
tool that looks for spyware and other forms of malware.
(You probably have this already.)
To run enter “
mrt.exe” at a DOS prompt (or use
However, another tool couldn't hurt.
Microsoft provides pretty good antivirus and firewall utilities.
Other malware removal tools I like include
Ad-Aware from Lavasoft (AdAware.com),
One of the largest network component companies in the world, Cisco Systems maintains a lot of useful technical information. Especially useful for studying for Networking Technologies or Service and Support Novell exams.
HCC provides hands-on Cisco Networking CCNA training by providing four Cisco Networking Academy classes which together fully prepare one for the CCNA exam, and a career in Cisco Network Administration. Check out some Cisco instructional resources and HCC Cisco Academy Course Descriptions.
Most of the free Unix and Linux software is actually GNU software, a project of the Free Software Foundation. To find out about supporting this group, or to get the latest versions of some of the best software around, visit them at www.gnu.org.
You can get various Linux distributions (CD images, you download these, burn CDs, then boot from those) such as Fedora and Red Hat, from iso.LinuxQuestions.org. A lot of information on various Unix and Linux distributions, including rankings, news, and links, can be found at distrowatch.com.

Textbooks are expensive! You might save some money by exploring your options. In addition to used copies, students may be able to get free shipping from an on-line vendor (Amazon.com has (or had, last time I checked) free second day shipping for textbooks, for students. However you must opt-out of the deal before one year has passed, or you'll be charged around $80.00.) You may be able to rent the book for the term (from Chegg.com for example). Other options you should look into include purchasing an e-book copy instead, or even find a copy in the library. The HCC bookstore also has some cheaper options in some cases; just ask!
