Existing computers can be made to last longer by refurbishing them and using open source software (OSS), thus curbing e-waste, said Sibongile Mabusa, from the Meraka Open Source Institute, at the e-Waste Management Conference, in Pretoria.
"OSS provides flexibility to allow programs to be stripped down so they use less memory and less processing power. These can then be used in an appropriate context," said Mabusa.
She added the pick and mix approach of Linux allows outdated hardware to use new formats.
"OSS can be used in a thin client network where old machines act as dumb terminals and receive services from a powerful server," she noted. Mabusa added this scenario works best at training centres or schools where users only need basic applications, such as word processing, browsing and e-mailing.
Mabusa maintains old machines can be given a new lease on life. "Rather than throwing out old machines, they can be used as hardware optimised by OSS."
