My daily readings 06/04/2013

    • Kahneman, a winner of the Nobel Prize for economics, distils a lifetime of research into an encyclopedic coverage of both the surprising miracles and the equally surprising mistakes of our conscious and unconscious thinking. He achieves an even greater miracle by weaving his insights into an engaging narrative that is compulsively readable from beginning to end. My main problem in doing this review was preventing family members and friends from stealing my copy of the book to read it for themselves.
    • Kahneman presents our thinking process as consisting of two systems. System 1 (Thinking Fast) is unconscious, intuitive and effort-free. System 2 (Thinking Slow) is conscious, uses deductive reasoning and is an awful lot of work. System 2 likes to think it is in charge but it’s really the irrepressible System 1 that runs the show. There is simply too much going on in our lives for System 2 to analyse everything. System 2 has to pick its moments with care; it is “lazy” out of necessity.

    • The world desperately needs a modern version of Hypercard that lets *non-programmers* easily create and link entire new storehouses, repositories and novel worlds of information and aesthetic creations.
    • When Dreamweaver and it’s ilk started becoming a requirement for non-coders, that’s when stylish webpage creation started to move out of reach for non-coders. Apple did well with iWeb, which was good for non-coders (even if it spat out spaghetti code), but have now ended development on it. WordPress and similar, also the various wiki-sites, are doing a good job of enabling non-coders to share info, but they lack the ‘3D’ soul that HyperCard had.
    • One poster mentioned SuperCard, which is still available. The other branch in the Hypercard family tree was MetaCard, which an enterprising Scotsman named Kevin Miller developed for and ultimately purchased and evolved into a modern product named LiveCode. His company, Runtime Revolution, is headquartered in Edinburgh, Scotland. The website is <!– m –>http://www.runrev.com/<!– m –>

      There is a 30-day free trial and a personal use license is $99. I’m still using stacks I wrote when Hypercard came free on my Mac SE, thanks to RunRev. The language can code for iOS and Android now, so tablets and phones can run your stacks.

      I wish the author of this article had known about it and could have mentioned it in the text.

    • HyperCard was originally released in 1987 for $49.95 and was included for free with all new Macs sold at the time.[2] It was withdrawn from sale in March 2004, although by then it had not been updated for many years.
    • HyperCard is based on the concept of a “stack” of virtual “cards”.[3] Cards hold data, just as they would in a rolodex. Each card contains a number of interactive objects, including text fields, check boxes, buttons, and similar common GUI elements. Users “browse” the stack by navigating from card to card, using built-in navigation features, a powerful search mechanism, or through user-created scripts.[4]
    • When the user invokes actions in the GUI, like clicking on a button or typing into a field, these actions are translated into “events” by the HyperCard runtime. The runtime then examines the script of the object that was the target of the event, like a button, to see if its script object contains code for that event, code known as a “handler”. If it does, the HyperTalk engine runs the handler, if it does not, the runtime examines other objects in the visual hierarchy.
    • These concepts make up the majority of the HyperCard system; stacks, backgrounds and cards provide a form-like GUI system, the stack file provides object persistence and database-like functionality, and HyperTalk allows handlers to be written for GUI events. Unlike the majority of RAD or database systems of the era, however, HyperCard combined all of these features, both user-facing and developer-facing, in a single application. This allowed rapid turnaround and immediate prototyping, allowing users to author custom solutions to problems with their own personalized interface. “Empowerment” became a catchword as this possibility was embraced by the Macintosh community, as was the phrase “programming for the rest of us”,[5] that is, anyone, not just professional programmers.
    • of “properties”. For example, buttons are a type of object, and come in standard styles. To determine, say, whether a checkbox style button is in fact checked, a script can simply call the “checkmark” property, which would return either true or false. In a similar way, objects can be analyzed via functions. For example, the number of lines in text field (another type of object) can be det

    • I have found that, in addition to the obvious strategies of student-driven, authentic inquiry-based projects that scaffolded, collaborative journal writing is helpful to move kids beyond the social comments.  Here are some sentence starters I have used.
    • The ‘planning’ starters might be used at the beginning of the work session; the ‘reflection’ starters at the end.  The ‘comment or discussion’ starters can be used to help kids give more substantive feedback to peers.  The ‘elaboration triggers’ are connecting words or phrases that can be used to help kids extend their thinking beyond what they might otherwise. So once they write something, they are encouraged to check the list of ‘elaboration triggers’ to think more deeply.

       

      These starters are obviously designed to address the issue of moving the learner along the continuum from novice to expert.
