We have covered memoizers in the past, but John Hann has posted on a nice implementation that takes advantage of closures, arity, and recursion -- 3 concepts/features that Javascript was meant to use. It leads to this generic version: PLAIN TEXT JAVASCRIPT: // memoize: a general-purpose function to enable a function to use memoization Read the rest...

One of the dirtiest secrets of the Internet is that it runs on ads for monetization. All of us who surf the web and use systems had lots and lots of free lunches because of advertisements being shown on web sites. The only difference to TV is that they are less obtrusive and you can Read the rest...

Ah Rico. It was a big shot when Ajax jumped on the scene and Bill Scott was lashing up the accordion landscape. Now time has moved on, and Bill keeps feeding us with usability goodness, but what about Rico? Well, Matt Brown is now on the case and has an early preview of Rico 3.0 Read the rest...

There was a cheer when Doug showed people that the module pattern could nicely give you somewhat "private" access in JavaScript. At least, the Java folk definitely cheered. Jonathan Snook on the other hand has no love for the module pattern and, after using it for some time, now avoids it: Avoiding the Module Pattern Read the rest...

John has been working on a very fun scrabble typing game called Deep Leap and although he hasn't finished it yet, people found it (John, time to learn about .htaccess ? ;) Just to tease him a little more and get the word out before it is finished, check it out!

It's no secret that we're mightily impressed with the fine work of the 280 North crew, what with 280 Slides, Cappuccino, Atlas, working with SOFA to make Aristo free for other projects to use, and that whole Objective-J thing which we'll never use but we love nonetheless. ;-) Francisco Tolmasky, one-third of the team, started Read the rest...

I am a big fan of YQL, a terribly easy and fuss-free way to access APIs and mix data retrieved from them in a simple, SQL style language. Say for example you want photos of Paris,France from Flickr that are licensed with Creative Commons attribution, you can do this with a single command: PLAIN TEXT Read the rest...

Andrea Giammarchi has a vision to have the best of all browsers available to him in JavaScript land. He has created vice versa as a project to explore this ideal and incredibly hard vision to attain: Studying the DOM, which is notoriously a mess, I often "travel" between the MDC and the MSDN to solve Read the rest...

Elijah Grey has a very cool new script CiteDrag that "adds automatically citation (ie. blockquotes, text quotes, ect.) to any dragged content off of the website which is using the script. CiteDrag requires no additional setup other than include the script somewhere on your website." I just dragged that above text from my blog post Read the rest...

Nic Volanschi pointed us to myPatterns: myPatterns is a new library adding custom notations for data structures in JS (and also C). It's really useful for writing elegant programs using general pattern matching. To explain myPatterns, let's introduce a standard JavaScript object: PLAIN TEXT JavaScript: { name: { firstname: "John", lastname: "Smith" }, Read the rest...

Myk is one of the nicest chaps that I have had the pleasure to sit closely to in Mozilla building "S". He has a nice little tip on the many syntaxes that you can use to iterate over arrays in various JavaScript implementations and standards. Some folks had some interesting points on the various approaches: Read the rest...

In the "it-had-to-be-done-at-some-point" category, we give you James Hall's latest project: I have started working on jsPDF, an entirely Javascript-based PDF generator. Currently the demo serves up the generated PDF as a Data URI, but it could be used on the server side or within browser extensions. It currently only supports simple text, but I'm Read the rest...

Atul Varma, a fantastic colleague in Building "S" at Mozilla, has been playing with a JavaScript implementation of CouchDB called BrowserCouch: BrowserCouch is an attempt at an in-browser MapReduce implementation. It's written entirely in JavaScript and intended to work on all browsers, gracefully upgrading when support for better efficiency or feature set is detected. Not Read the rest...
