    Welcome to Blocky.io, the home page for the Blocky programming language. Blocky is a visual programming system written in Common Lisp designed for multimedia authoring and general user programming. In addition to borrowing ideas from GNU Emacs, the language design is heavily influenced by existing visual programming research projects such as PureData, Squeak, Self Morphic, MIT Scratch, Berkeley's Build Your Own Blocks, and more recently Jens Moenig's Smalltalk Elements.

    I think Scratch →Greenfoot → Eclipse is a good path for Scratch users who want to get deeperinto programming. And many Scratch users may not go on to learn Java ormajor in computer science, just as most of us who took music lessons did notgrow up to become professional musicians.[SC] This is something I really like about Scratch (and its fail-soft strategy).In a sense, I think this had been one of the original goals of Alice; I don't listin my article largely because it became challenging to realize in practice (3D issomewhat of a culprit here). I do agree that the transitions Scratch → Greenfoot, Alice → Greenfoot, and Scratch → Alice → Greenfoot wind up making agreat deal of sense in terms of what gets exposed to the student.

    "Security researchers have discovered that Apple's iPhone keeps track ofwhere you go - and saves every detail of it to a secret file on the devicewhich is then copied to the owner's computer when the two are synchronised." "Apple can legitimately claim that it has permission to collect the data:near the end of the 15,200-word terms and conditions for its iTunes program,used to synchronise with iPhones, iPods and iPads, is an 86-word paragraphabout "location-based services""

    "One thing is certain, and is unlikely to be news that's welcomed at Facebook HQ. There is a growing perception out there that Facebook isn't the safest of places to be," wrote Sophos senior technology consultant Graham Cluley in a recent blog post. Some of the key threats recently highlighted by Sophos are rogue applications or survey scams that pop up from users' own Facebook friends who have been tricked into clicking on an interesting looking news headline or YouTube video that then duplicates to everyone in their friend's list. It then directs them to click on a website or survey, or inadvertently download malware. One of the offenders now doing the rounds is a fake application that promises to let you see who has been viewing your profile.
