You may be aware that many systems run on some form of Linux these days. This is true of my web server, which uses Centos/Red Hat. When one of those rare problems arises, a bit of help is often needed. Here is a method for fixing up Centos files:
'shutdown -rF' will reboot the server and run fsck on all disks. For 'mySQL, 'mysqlcheck -Aor' will repair and optimise local databases.

CCTV development may increase misuse
A privacy expert says the developments of closed circuit television cameras (CCTV) may increase the misuse of the technology.
CCTV cameras are widely used privately and publicly, and while some say it gives an added sense of security, others consider it an invasion of privacy.
Questions are being raised over who controls the footage, where it ends up and whether it encroaches on our privacy.
Privacy lawyer John Edwards says users of CCTV are so far behaving responsibly, "but as technology develops, we are seeing things which can transform the usability of that."
"The possibility of misuse expands with expanding technology and we do need to be conscious of this and monitor the developments."
Edwards says currently there are no specific laws on how CCTV cameras are operated, that they are just one of many technologies regulated under the general Privacy Act.

The so-called $100 laptop has undergone a facelift in order to be used by secondary school children.
The machines, designed by One Laptop per Child (OLPC), are based on the original XO laptop, which was built for primary school children.
The new computers feature a larger keyboard and upgraded software.
Uruguay, which has already distributed nearly 400,000 XO laptops to primary schools, has ordered 90,000 of the new laptops, known as the XO-HS.
It has also ordered 10,000 machines designed by rival Intel, which makes the Classmate PC, also developed for children.
"We want to see how students react and analyze the advantages and disadvantages of each," said Miguel Brechner, director of the Technological Laboratory of Uruguay, who is in charge of the country's Plan Ceibal (Education Connect) project.

News:Ofcom unveils anti-piracy policy
Lists of Britons who infringe copyright are to be drawn up by the UK's biggest ISPs, under proposals from the regulator Ofcom.
The plan is contained in a draft code of practice it hopes will curb copyright infringement.
Names and the number of times individuals infringe will be logged.
Music firms and movie studios can request details from the list so that they can decide whether to start their own action against serial infringers.
However, any suspected infringers will be sent three warning letters before any action can be taken.

Robot-inflicted injuries studied
A future in which robots help around the home could prove harmful to humans, suggests a study.
German researchers studied what happens in accidents involving robots using sharp tools alongside humans.
They used a robot arm holding a variety of bladed tools programmed to strike test substances that mimic soft tissue.
In some cases, the researchers found, the robots managed to accidentally inflict wounds that would prove "lethal".
The tests were conducted to see if a prototype safety system could limit the damage done.
