What's a JavaScript Closure? Ever wonder about some of JavaScript's more advanced and esoteric features? Nathan Whitehead's interactive tutorial explains and walks through each of these concepts one step at a time. At the end of each lesson, you are encouraged to write short snippets of code demonstrating the concepts that you just learned, which are then automatically checked for errors and verified.
Perhaps you're new to JavaScript, or programming in general;
CodeAcademy offers similar interactive tutorials that will teach you the basics, and hold your hand along the way. Perhaps you'd rather learn at a more even pace; CodeAcademy's
CodeYear will introduce you to one new concept every week throughout 2012.

Released yesterday,
dabblet joins an array of live sandbox tools designed to prototype, test and share webcode that includes
JSFiddle and
CSSDesk, while
bringing some advantages of its own.
Other useful resources:
w3clove validates an entire site, rather than page-by-page;
JQuery Air teaches you how to use the framework directly in the browser;
domain.nr finds clever TLDs for your site, and
Sequel Pro is a nice, free, native, open source MySQL editor for OS X. If you’re more the old-school dead-tree type, there’s always
The Manual.

Behold the
N Building, a new structure in a Tokyo shopping district that at first glance looks kind of like a giant Tetris screen until you realize that the fancy geometric design on its facade isn't merely ornamental: It's code—
QR code, to be exact. What that code allows passersby to do is quite unique. [

Thomas Jefferson's cipher message from Robert Patterson For more than 200 years, buried deep within Thomas Jefferson's correspondence and papers, there lay a mysterious cipher -- a coded message that appears to have remained unsolved. Until now.... To Mr. Patterson's view, a perfect code had four properties: It should be adaptable to all languages; it should be simple to learn and memorize; it should be easy to write and to read; and most important of all, "it should be absolutely inscrutable to all unacquainted with the particular key or secret for decyphering."

It's no secret that
amateur radio operators, or hams, often build their own equipment. Especially with the aid of antenna tuners, most anything can be used as an antenna. One group of hams took this to the extreme, using
ladders and shopping carts as antennas as they started an annual competition that would eventually see
trucks,
train tracks, a
tree, and even a pair of
exercise machines and
a football stadium used. I stumbled across the site last night, and it turns out that this year's competition is
this weekend! Ham radio, by the way, no longer requires a
Morse code exam, just a set of questions on electrical and operations theory. Those curious can take
practice tests online, since the FCC releases the question pools.

"This is the story of when I re-wrote the Lotus Notes Formula Engine.... So here was I was, offered this position that I clearly wasn't qualified for. I had no experience with language runtimes or compilers, I knew very little about C and didn't know anything about C++, I had never dealt with platform byte ordering and packing and all the other issues associated with writing something for eight different operating systems, I had never even used proper version control. But none of that mattered to me. It seemed to me like an amazing opportunity and I would be doing exactly the kind of stuff I enjoy most..."
