It seems that Bitcoin is only designed to eliminate the need for centralized issuer and central authority, but not anonymity, which is a common misconception among internet users as according to one of its developers (Jeff Garzik), transaction is recorded in public log and although the identity of the parties involved can’t be directly identified, the transaction can be easily traced and linked to other accounts through data mining and statistical analysis.
So it is harder to stay anonymous in transactions that involve large currency value.

Busy websites which has a lot of insert/delete transactions may introduce fragmentation in MySQL tables. Fortunately, users and optimize mysql tables with ‘OPTIMIZE TABLE’ command, but how to execute it automatically?
Here’s how:
The mysql-client package in Ubuntu installation comes with a tool called mysqlcheck which is handy for optimizing table in mysql. This command can be executed from bash and can be executed using cron.
to do that, just run this command.
[bash]
cron -e
#in the crontab file– add this line
59 23 * * * /usr/bin/mysqlcheck -o -v -u <mysql username> -h localhost <database_name> -p <password>
[/bash]
This will tell cron to execute mysqlcheck and optimize mysql table of the specified database exactly on 11:59pm, every day. You can change the setting to suit your need.
A bit of advice when starting up an e-commerce (especially storefront) site, please use proper e-commerce software for the job. Do not ‘force’ a general-purpose (CMS) to be an e-commerce site via plugins (or *cough* *cough* ‘component’), it’s gonna be a pain-in-the-ass to secure ’em.
So do yourself (and the sysadmin guys) a favor, use a proper e-commerce software platform or just turn to blogger.com for selling your stuffs…
Although security by obscurity is not the best policy to protect your IS assets, but it is still useful to thwarts simple network scanner or newbie crackers.
Note: This tip is written for Ubuntu Linux, the steps is similar to other GNU/Linux distro, albeit with a slight variant.
