Breakfast briefing: Twitter now screening links to protect users

• After a spate of phishing scams and attacks, Twitter is cranking up safety for users by blocking all dubious links . Essentially it routes all links through Twitter's filter and eliminates the bad ones before potential victims reach the destination. Looks like good news for users - but possibly bad news for the URL shortening services that have emerged in Twitter's wake? • If you're looking for some fun reading, it's worth taking some time to look through the blog of Jonathan Schwartz . Now liberated from his job at Sun Microsystems , Schwartz is delivering a few stories of his time at the company - the sort of things he couldn't say while there. The latest morsel? Tales of patent bluster with Steve Jobs, Bill Gates and others . And there are fighting words in there: while he says he gets the value of patents, he also believes that "for a technology company, going on offense with software patents seems like an act of desperation". • And it's time to tune in again to the latest edition of our Tech Weekly podcast , headed by the effervescent Aleks Krotoski. the latest show features a dissection of the BBC's apparently contradictory digital plans - is it pushing out or pulling back? - and a look inside San Francisco's wonderful mechanical museum.
