hai paul check this out.......# News reports in May of 2006 described a multi-million dollar lawsuit settlement paid by a healthcare software vendor to one of its customers. It was reported that the customer claimed there were problems with the software they had contracted for, including poor integration of software modules, and problems that resulted in missing or incorrect data used by medical personnel.# In early 2006 problems in a government's financial monitoring software resulted in incorrect election candidate financial reports being made available to the public. The government's election finance reporting web site had to be shut down until the software was repaired.# Trading on a major Asian stock exchange was brought to a halt in November of 2005, reportedly due to an error in a system software upgrade. The problem was rectified and trading resumed later the same day.# A May 2005 newspaper article reported that a major hybrid car manufacturer had to install a software fix on 20,000 vehicles due to problems with invalid engine warning lights and occasional stalling. In the article, an automotive software specialist indicated that the automobile industry spends $2 billion to $3 billion per year fixing software problems.# Media reports in January of 2005 detailed severe problems with a $170 million high-profile U.S. government IT systems project. Software testing was one of the five major problem areas according to a report of the commission reviewing the project. In March of 2005 it was decided to scrap the entire project.

1) In February of 2009 users of a major search engine site were prevented from clicking through to sites listed in search results for part of a day. It was reportedly due to software that did not effectively handle a mistakenly-placed "/" in an internal ancillary reference file that was frequently updated for use by the search engine. Users, instead of being able to click thru to listed sites, were instead redirected to an intermediary site which, as a result of the suddenly enormous load, was rendered unusable.

2) In January 2009, Google's search engine erroneously notified users that every web site world wide was potentially malicious, including its own.

3) In August of 2008 it was reported that more than 600 U.S. airline flights were significantly delayed due to a software glitch in the U.S. FAA air traffic control system. The problem was claimed to be a 'packet switch' that 'failed due to a database mismatch', and occurred in the part of the system that handles required flight plans.

4) In order to fix a warning issued by Valgrind, a maintainer of Debian patched OpenSSL and broke the random number generator in the process. The patch was uploaded in September 2006 and made its way into the official release; it was not reported until April 2008. Every key generated with the broken version is compromised, as is all data encrypted with it, threatening many applications that rely on encryption such as S/MIME, TOR, SSL or TLS protected connections and SSH.

5) A bug in the code controlling the Therac-25 radiation therapy machine was directly responsible for at least five patient deaths in the 1980s when it administered excessive quantities of X-rays.
