If you want to stay heart healthy, you should exercise, eat right, not smoke, and… stay away from iPads? As Bloomberg reports, 14-year-old Gianna Chien has discovered that the 30 magnets in the iPad 2, which are used to hold the Smart Cover in place, could accidentally disable a pacemaker if the user falls asleep with the iPad on his or her chest. Apple warns of this danger on page 126 of the iPad User Guide, but how many of you read that far? Chien made the discovery while working on a science fair project, which sadly didn’t win first place. (We hope the media coverage of her project helps makes up for that!)

Despite recent complaints about iOS security, it’s effective against at least one group: law enforcement. According to Declan McCullagh at CNET, police departments around the country are sufficiently stymied by iOS device encryption that they’re turning to Apple for help. They’ve flooded Apple with so many requests for assistance decrypting confiscated iPhones that Apple is putting them on a waiting list of up to 4 months. Of course, the flip side of this story is the suggestion that Apple has a backdoor method of cracking iPhone encryption.

Developer and entrepreneur Peter Nixey has posted an open letter to Apple emoting about problems with and proposing solutions to managing photos on Apple devices. Nixey’s main complaints revolve around the lack of useful iOS tools for photo management, duplicates and confusion in Photo Stream, Photo Stream’s inability to sync videos, and devices with too little storage. He suggests a new paid Apple service that would store the canonical version of a user’s entire photo and video collection in iCloud, allowing access from any of that user’s devices. Fingers crossed that Apple realizes just how broken the current system is and addresses these and other complaints!

Apple’s tumultuous stock price has pushed it into and out of the top spot among U.S. companies by market capitalization, but that doesn’t help with the Fortune 500 list, which ranks companies by gross revenue. Not that Apple’s doing badly there either — in the 2013 Fortune 500, Apple jumps from 17th place all the way to 6th, cracking the top 10 for the first time and giving a more accurate picture of how Apple compares with other corporate giants.

Writer, counselor, and longtime TidBITS reader Gary Bloom has tapped out an elaborate comparison of writing apps for iOS, in which he cleverly compares each one to a house. He even kindly mentions our review of Nebulous Notes; though it’s not our “favorite” writing app, per se, we just liked it enough to give it a review! If you write on your iPad, this article is a must read — his favorite app may surprise you.

On 30 April 1993, the organization behind the creation of the Web, CERN, officially put the World Wide Web project software — line-mode client, basic server, and common code library — into the public domain. And history was thus written by Tim Berners-Lee, with significant help by Robert Cailliau. You can now read more of that history, and see both the first Web site and the original legal documents, at the site that CERN has put up to celebrate this momentous anniversary. (Adam here. Little did I know, when I met Cailliau at the Hypertext ’93 conference in Seattle, exactly with whom I was having lunch and helping with directions to where he could shop for his teenage daughter. I was somewhat embarrassed, since I hadn’t said complimentary things about his MacWWW browser in my “Internet Starter Kit for Macintosh” book, given that the software was primitive and very buggy, but he was nonetheless very kind.)

About a year ago, Tor Books, the highly regarded publisher of science fiction and fantasy, announced that they were dropping digital-rights-management protection on all of their ebooks. Now, Julie Crisp of Tor UK has revealed what that decision has meant in terms of ebook piracy: “As it is, we’ve seen no discernible increase in piracy on any of our titles, despite them being DRM-free for nearly a year.” (This, of course, is no surprise to us: we have been publishing our Take Control ebook DRM-free for nearly ten years, with exactly the same results.) Equally heartening to Tor is how much support their authors have for the DRM-free policy.

When we think of old communications technology, many of us picture 10Base-2 coax connectors or maybe 2400 baud modems. But what about wax-covered cardboard discs? The Smithsonian discovered and digitized such a disc containing the voice of Alexander Graham Bell saying, "Hear my voice, Alexander Graham Bell." Now you can hear what the inventor of the telephone sounded like on 15 April 1885.
