If you need a catalog system for your web page, this product may be just what you are looking for.
Administration

At the heart of MiniVend is the Products database. Normally, it is just an ASCII file with fields separated by tabs. The field names are given in the first row and MiniVend indexes the database with GDBM (GNU Database Manager) automatically. You can even hook up to a real SQL database through Perl's unique DBI interface, if you already have one.

You can update the database on the command line with the offline command, or if you just want to change one record, you can use the update command.

It is possible to import data from any source, provided the data can be formatted with the fields separated by tabs. If you want to adjust all the prices in the system, it is easy to do so with the commonadjust feature.

MiniVend records all sessions for future use. Obviously, some session data will become obsolete after a while, so it is a good idea to put an expire script in your crontab file:

44 4 * * * /home/httpd/mvend/bin/expireall -r

This will prevent your session databases from growing too large.

Conclusion

MiniVend is very impressive, almost awesome. This is software of a kind that other companies ask thousands of dollars (or euros) for, and MiniVend is free through the GPL. It is also a showpiece, demonstrating the versatility of Perl. A shopping cart system is not a small piece of code; MiniVend is a full-featured, powerful example.

MiniVend is a big system, not something you can cover in one session. It has scores of features I didn't even have time to try out yet. I've had a few problems with it, but I firmly believe that MiniVend is a system that can be used for any kind of electronic commerce. As I learn the features and study the code, I will become more familiar with it and can make it do all the things I want it to do.

If you're looking for a turn-key system, MiniVend is not it. On the other hand, if you are looking for a powerful, flexible and easy-to-use system, MiniVend is for you. The documentation is great, the source code is all there and if the support on the mailing list scales up a bit, there is nothing to fear.

Thanks, it seems some what simple though. I am not sure if it would be good enough for long-term online growth. I think Magento or osCommerce would be a great bet as shopping cart software. But at the end of the day it comes down to users-needs and what they feel comfortable with.

Thanks,
Richard.

Fabric-Based Computing Enables Optimized Hyperscale Data Centers

Today’s modular x86 servers are compute-centric, designed as a least common denominator to support a wide range of IT workloads. Those generic, virtualized IT workloads have much different resource optimization requirements than hyperscale and cloud applications. They have resulted in a “one size fits all” enterprise IT architecture that is not optimized for a specific set of IT workloads, and especially not emerging hyperscale workloads, such as web applications, big data, and object storage. In this report, you will learn how shifting the focus from traditional compute-centric IT architectures to an innovative disaggregated fabric-based architecture can optimize and scale your data center.

Red Hat White Paper: Using an Open Source Framework to Catch the Bad Guy

Built-in forensics, incident response, and security with Red Hat Enterprise Linux 6

Every security policy provides guidance and requirements for ensuring adequate protection of information and data, as well as high-level technical and administrative security requirements for a system in a given environment. Traditionally, providing security for a system focuses on the confidentiality of the information on it. However, protecting the data integrity and system and data availability is just as important. For example, when processing United States intelligence information, there are three attributes that require protection: confidentiality, integrity, and availability.
