According to Caleb Sima, CTO, SPI Dynamics, SQL Injection flaw occurs when external input is transmitted directly into a SQL string and into a database. This allows an attacker to piggyback SQL commands onto that string and manipulate or steal database information or execute system commands. I personally had come across a lot of this flaws especially when doing simple web scripting. Most users when doing insertion and updates to database via text input based on html forms, never check for invalid characters that could lead to this type of attack.
Me and my collegues where a fortunate few who managed have our machine upgraded to have 1Gigabyte of RAM. However, during the upgrade process our vendor faced a lot of dificulties as most of the machines refuse to boot and some were throwing memory errors when booted or running. The reason he gave was that our original memory installed were from Taiwan and the new ones were from China. When I came across this article about RAM specifications, I think it is because the memory that he tried to install was incompatible with the current RAM or mainboard. There seem to be a lot of other specifications other than the bus speed or the size of the memory that we need to determine to be compatible and suited to our systems before we plug it in. Most of our vendor, technicians and system administrators will never had hear of the terms CAS/tRCD/tRPD/tRAS.

Sage, an rss reader extension for firefox.
newsmonster is said to be a great rss reader for mozilla and netscape. however, when i installed it in firefox, it broke my firefox and there was no easy way to remove it. I had to manually search for all the references in the xml files and remove it. hopefully it did not break anything else. Now i will resort to SAGE one of the firefox's extension.
