Write Code Every Day
Last fall, work on my coding side projects came to a head: I wasn’t making adequate progress and I couldn’t find a way to get more done without sacrificing my ability to do effective work at Khan Academy .

10th Anniversary of JQuery
Today marks the 10th anniversary of the release of jQuery. I announced it back at BarCamp NYC 2006 when I was still in college. It’s incredible to think of how far it’s come and just how many people have contributed to its success. To them I am forever grateful, thank you.

Eulogy to _why
Unfortunately I’m short on time at the moment (trying to launch a project this week) but I have to say, at least, a few words about the hacker and artist _why .

John Resig: JavaScript as a First Language
At Khan Academy we’ve been investigating teaching Computer Science to students in some new and interesting ways. The most interesting aspect of which is that we’re likely going to be teaching them JavaScript as their first language.

Google Groups is Dead
For the jQuery project we’ve run all of our community discussions through Google Group mailing lists for the past three years. At this moment the main jQuery group is the second most popular programming group (next to Android developers) clocking in at over 21,000 members. We also have the jQuery Dev and jQuery UI…

WebKit is the jQuery of Browser Engines
The news has just come out that Opera is switching all of their browsers (both mobile and desktop) to use WebKit (specifically, Chromium). I’ve seen a lot of gnashing of teeth on Twitter and I feel like I can respond because I use to feel the same way back in 2008-2009. However this is 2013 and the Chrome/Chromium…

Using Waifu2x to Upscale Japanese Prints
In my spare time I’ve been working on a database of Japanese prints for a little over 3.5 years now. I’m fully aware that I’ve never actually written about this, personally very important, project on my blog — until now. Unfortunately this isn’t a post explaining that project. I do still hope to write more about the…

Asm.js: The JavaScript Compile Target
Like many developers I’ve been excited by the promise of Asm.js . Reading the recent news that Asm.js is now in Firefox nightly is what got my interest going. There’s also been a massive surge in interest after Mozilla and Epic announced ( mirror ) that they had ported Unreal Engine 3 to Asm.js – and that it ran…

Gittip at Khan Academy
For a while now I’ve been a huge fan of Gittip . I think they’ve created one of the most interesting models for funding Open Source development.

John Resig: Secrets of the JavaScript Ninja Update
Jeff Atwood wrote up a post today on the merits of writing a technical book in this day-and-age and specifically called out my past post on programming book profits and my work-in-progress Secrets of the JavaScript Ninja .

Learning from Twitter
An issue popped up on Twitter this past week that caused the web site to be generally unusable for many users. It appears as if attempts to scroll were unbearably slow and caused the site to be unresponsive.

Deep Tracing of Internet Explorer
After reading a recent post by Steve Souders concerning a free tool called dynaTrace Ajax , I was intrigued. It claimed to provide full tracing analysis of Internet Explorer 6-8 (including JavaScript, rendering, and network traffic). Giving it a try I was very impressed. I tested against a few web sites but got the…

Node.js Stream Playground
This summer I had the opportunity to attend NodeConf and it was a fantastic experience. I really appreciated how every session was a hands-on coding session: I felt like I walked away knowing how to put a bunch of advice directly into practice.

Using the Google Cr-48 for Coding
The other day I saw the announcement for the new Chrome OS test laptop and decided to sign up on the off-chance that I might be able to snag one. In the request form I made it very clear that I would be attempting to use this laptop for development (easily my primary activity). Surprisingly the laptop arrived this…

JavaScript Trie Performance Analysis
After my last post discussing dictionary lookups in JavaScript the unanimous consensus seemed to be that utilizing Trie would result in additional space savings and yield performance benefits.

Processing ported to JavaScript
As a sort-of reverse birthday present I’ve decided to release one of my largest projects, in recent memory. This is the project that I’ve been alluding to for quite some time now :

Keeping Passwords in Source Control
I learned a neat tip from my co-worker, Craig Silverstein ( more on Craig joining Khan Academy ), recently and I thought others might find it to be useful.

John Resig dissects the neural network javascript OCR captcha code
A pretty amazing piece of JavaScript dropped yesterday and it’s going to take a little bit to digest it all. It’s a GreaseMonkey script, written by ‘ Shaun Friedle ‘, that automatically solves captchas provided by the site Megaupload . There’s a demo online if you wish to give it a spin.

Mozilla Test Swarm Alpha Open
TestSwarm , the project that I’ve been working on over the past 6 months, or so, is now open to the public. Mozilla has been very gracious, allowing me to work on this project exclusively. At the beginning of April I moved from my old position as a JavaScript Evangelist on the Mozilla Evangelism team to that of a…

John Resig on TraceMonkey
I’ve been waiting to blog about this for a long time now. A fantastic new improvement to Mozilla’s JavaScript engine (SpiderMonkey) has landed. Code-named TraceMonkey this engine utilizes a techniques, called trace trees (PDF), which adds just-in-time native code compilation to SpiderMonkey.

Computing with JavaScript Web Workers
Web Workers are, undoubtedly, the coolest new feature to arrive in the latest version of web browsers. Web Workers allow you to run JavaScript in parallel on a web page, without blocking the user interface.

John Resig Talk: Performance Improvements in Browsers
I gave a talk last week at Google (at the request of the excellent Steve Souders ) all about the performance improvements, and new APIs, that are coming in browsers. I cover the new browsers, their JavaScript engines, their JavaScript performance, and then do a whirlwind tour of their new DOM methods and some of their…

Picking Time
It’s not often that new user interface conventions are born – or popularized. Even less so within the realm of web development. I’d argue that Sparklines and Lightbox are two of the best examples of UI conventions that were popularized on the web.

John Resig - Simple JavaScript Inheritance
I’ve been doing a lot of work, lately, with JavaScript inheritance – namely for my work-in-progress JavaScript book – and in doing so have examined a number of different JavaScript classical-inheritance-simulating techniques. Out of all the ones that I’ve looked at I think my favorites were the implementations…
