What Keong doesn't tell his readers is the truth about hackers. Hackers were considered hardworking and respectable computer folk for years. And they still are that. What has changed is that nowadays the media tags every online criminal with the name hacker. The people they are really referring to are crackers not hackers.
Crackers like to bypass security in computer systems.
The upshot of Keong's article is job discrimination. Keong calls on employers not to hire hackers. And if anything makes Keong's sort of crap journalism worse, it is that people like him have been having great success in recent years. Not in getting hackers fired but in getting service providers and net companies to fire scads of employees that dress in an alternative fashion. So the Globe will have you out of a job, but there's no need to worry.
