Incident Raises Concerns About a More Formal Spec For Bitcoin
An anonymous reader writes: Aberrant treatment of transactions by Bitcoin miners has renewed concerns that Bitcoin as a protocol may need a stronger specification. OpenBSD savior and Bitcoin entrepreneur Mircea Popescu raised this issue back in 2013 that the current attitude of "the code is the spec" was introducing fragility and harming Bitcoin's vital decentralization. While a lot of fuss has been made about the maximum blocksize, perhaps formalizing the protocol and breaking the current mining cartel is a more urgent and serious problem. The debate going on resurrects many of Datskovskiy's early concerns about Bitcoin's fragility including mining as a necessary bug, but a bug nonetheless. -
DIY Augmented Reality Heads-Up Display
mkwan writes "A PhD student in Melbourne, Australia, has built an augmented reality head-up display using a baseball cap, an Android smartphone, and off-the-shelf optics. It won't win any awards for style or practicality, but it's a fun way to use Wikitude. All we need now is a Terminator-vision smartphone app." Not nearly as modern, but vaguely related: the Private Eye P4. -
Why Was Hypercard Killed?
theodp writes "Steve Jobs took the secret to his grave, but Stanislav Datskovskiy offers some interesting and illustrated speculation on why HyperCard had to die. 'Jobs was almost certainly familiar with HyperCard and its capabilities,' writes Datskovskiy. 'And he killed it anyway. Wouldn't you love to know why? Here's a clue: Apple never again brought to market anything resembling HyperCard. Despite frequent calls to do so. Despite a more-or-less guaranteed and lively market. And I will cautiously predict that it never will again. The reason for this is that HyperCard is an echo of a different world. One where the distinction between the "use" and "programming" of a computer has been weakened and awaits near-total erasure. A world where the personal computer is a mind-amplifier, and not merely an expensive video telephone. A world in which Apple's walled garden aesthetic has no place.' Slashdotters have bemoaned the loss of HyperCard over the past decade, but Datskovskiy ends his post on a keep-hope-alive note, saying: 'Contemplate the fact that what has been built once could probably be built again.' Where have you gone, Bill Atkinson, a nation of potential programmers turns its lonely eyes to you."
