Parallel Javascript
Lately the ideas for a parallel, shared memory JavaScript have begun to take shape. I’ve been discussing with various JavaScript luminaries and it seems like a design is starting to emerge. This post serves as a documentation of the basic ideas; I’m sure the details will change as we go along. User Model The model is that a JavaScript worker (the “parentâ€) may spawn a number of child tasks (the “childrenâ€). The parent is suspended while the children exe...

On Erlang's Syntax
I first planned to release this text as an appendix entry for Learn You Some Erlang, but considering this feels more like editorial content and not exactly something for a reference text, I decided it would fit better as a blog post. Many newcomers to Erlang manage to understand the syntax and program around it without ever getting used to it. I've read and heard many complaints regarding the syntax and the 'ant turd tokens' (a subjectively funny way to refer to ,, ; and .), how annoying...
Code reviews in the 21st Century
There's an old adage that goes something like: 'Do not talk about religion or politics'. Why? Because these subjects are full of strong opinions but are thin on objective answers. One person's certainty is another person's skepticism; someone else's common sense just appears as an a prior bias to those who see matters differently. Sadly, conversing these controversial subjects can generate more heat than light. All too often people can get s...

Interview Programming Problems Done Right
Introduction Why 37signals Doesn't Hire Programmers Based on Brainteasers and my comment on HN generated a lot of responses, so much so that I'm writing this post to properly explain the essence of a good (IMHO) interview programming problem. Pascal's Triangle Pascal's Triangle is a shortcut for getting coefficients most often used binomial probability. The root element is 1. Every other element is the sum of the one or two above it (diagonally left and diagonally right). There are severa...

The Problem With Client-Side Analytics
Client-side analytics is broken. The numbers produced by it are trivially spoofable by competitors and nefarious characters. Most websites use client-side analytics of one type or another and the only way to get numbers you can trust is to compare numbers from multiple providers and to take an average of the closest two.This post highlights the problem and proposes a partial solution that substantially mitigates the issues with minimal effort. Our proposed solution is simply to include a digital...

IE ActiveX(â€htmlfileâ€) Transport, Part II
In my last post I discussed using the ActiveX(â€htmlfileâ€) technique to provide a usable streaming transport in Internet Explorer. The solution I provided will work, but since writing the last article I’ve made significant progress in understanding why IE behaves the way it does with respect to the streaming transport. The previous solution amounted to creating an array of messages, pushing messages on that array from the htmlfile iframe, and popping messages off of the array i...

Simple Animation in the HTML5 Canvas Element
HTML5 is generating all kinds of buzz these days. Some of the buzz is about HTML5 being a replacement for Adobe’s Flash. I don’t think it’s there yet but it’s certainly on the way to changing the way content is presented on the web. This is a description of a very simple animation in an HTML5 canvas element. It is coded for readability and not for optimized operation. We’ll add a canvas element to a web page and then use javascript to draw on it. We will...

If a co-worker comes to you and asks you: "I would like to learn Perl, where can I find a good Perl Tutorial?", I am sure your would have a few recommendations.

Dave Cross responded by checking the top results when searching for "perl tutorial".It shows that many p...

About browser event
First look at following codes: var $ = KISSY.all; $(‘a’).on(‘click’,function(e){ doSomeThing();//This function seems very famous e.halt(); }); The above codes seem complete the work we want them. The browser will not redirect us to the link in href, but is there some issue with the codes above? Before explaining what's wrong with the above codes, we first need to understand some concepts. Browser default behavior When we click a link, the browser will redirect us to anoth...

The Long Grind Before You Become an Overnight Success
“So, what do you do?â€Ugh. I hated that question.The truth was that we were trying to start a new venture but we hadn’t really made any progress.But, instead of just muttering something, I would force myself to enthusiastically pitch our current struggling idea. They would nod along but the skepticism on their face was hard to ignore.And, when I was done, they would sometimes hit me with: “So, is that your full-time thing?†Ugh. What that really meant was: youâ€...
