Mobile Web Testing & Debugging Best Practices. Deconstructing Recommender Systems. Photo-illustration: Christina Beard One morning in April, we each directed our browsers to Amazon.com’s website.
Not only did the site greet us by name, the home page opened with a host of suggested purchases. IEEE-USA Today's Engineer. Five Strategies for Successful Engineering Management By Gary C.
Hinkle If you read surveys about the highest paying jobs in the United States, you'll notice that the median salary for engineering managers ranks not too far behind doctors, attorneys and CEOs (typical CEO base salary, not the extreme high end of the scale that often makes the news). HTML5 vs. Apps: Why The Debate Matters, And Who Will Win. HTML5 is a new technology that allows developers to build rich web-based apps that run on any device via a standard web browser.
Many think it will save the web, rendering native platform-dependent apps obsolete. So, which will win? Native apps or HTML5? A recent report from BI Intelligence explains why we think HTML5 will win out, and what an HTML future will look like for consumers, developers, and brands. Access The Full Report By Signing Up For A Free Trial Today >> Data Says R Amongst Most Popular Languages. Data Scientist Drew Conway tackles the problem of deciding which programming languages are the most popular in an interesting way: by comparing the number of projects tagged in GitHub with each language, and the number of questions in StackOverflow about the language.
The former is a measure of how often a language is used (though, mainly for open source projects); the latter is a measure of how many programmers are asking questions about it. Drew uses these measures and a k-means clustering technique to categorize langauges as follows: Most Popular (generally ranked in the highest 20% of languages in StackOverflow and GitGub)Second Tier (ranked in the 60%-80% quartiles)High Variance (ranked in the 20%-60% quartiles)Least Popular (ranked in the bottom 20-25%)Incomparable (because of indeterminate rankings in StackOverflow)
Roy. Google, Microsoft, Facebook and Others Launch Web Platform Docs, A Web Standards Documentation Site. A number of leading browser vendors and other tech companies, including Microsoft, Google, Apple, Adobe, Facebook, HP, Nokia, Mozilla, Opera and the W3C, just announced the launch of the Web Platform Docs project at WebPlatform.org.
The project aims to create “a new, authoritative open web standards documentation site,” says Opera Software. The wiki-like site, says Opera, wants to ensure that developers can easily find “accurate, quality information on all the latest HTML5, CSS4 and other standards features across the multitude of available web-based resources.” Currently, the companies behind WebPlatform.org argue, developers struggle to find authoritative answers to their questions about modern web technologies and often, developers have to resort to figuring out the right solutions through trial and error (the Google team describes this as a “scavenger hunt”).
The new site, says Adobe, will change this by providing developers a “single, definitive resource to go to.”
During that process, it identifies the most important keywords that cause the documents in the cluster to be considered similar to each other. The keywords give you a quick idea of what each cluster is about, and they allow you to easily identify the themes of your document set. Clustify reports the frequency for each keyword, and allows you to browse clusters containing a set of keywords you specify. Clustify also identifies a “representative document” for each cluster. W.T.F.M: Write The Freaking Manual - Floopsy. W.T.F.M: Write The Freaking Manual I will take this moment to reflect on what has been an epic exercise in utter frustration: Sifting through poorly written documentation or tutorials for an otherwise excellent programming language, framework, project, etc.
It seems that nowadays, the original phrase R.T.F.M. is also quickly becoming the need to W.T.F.M. Developers: You spend hours, days, months, perhaps years refining your masterpiece. It is an expression of your life’s work, heart and soul. Why, then, would you shortchange yourself by providing poor or no documentation for the rest of us? R Developer Page. Wordle - Beautiful Word Clouds. Walrus - Graph Visualization Tool. Source Code Available The source code to Walrus is now available under the GNU GPL.
You may download the source code below. Description Walrus is a tool for interactively visualizing large directed graphs in three-dimensional space. It is technically possible to display graphs containing a million nodes or more, but visual clutter, occlusion, and other factors can diminish the effectiveness of Walrus as the number of nodes, or the degree of their connectivity, increases.

Polaris.umuc.edu/~busilane/tman636/articles/12prin.pdf. JSON Tutorial. Introduction to Architecting Systems for Scale.
Few computer science or software development programs attempt to teach the building blocks of scalable systems.
Instead, system architecture is usually picked up on the job by working through the pain of a growing product or by working with engineers who have already learned through that suffering process. In this post I'll attempt to document some of the scalability architecture lessons I've learned while working on systems at Yahoo! And Digg. How to Build an Excellent Web or Mobile App. Sorting and searching at the library. If you ever want to screw over a library, just walk up to any shelf, pick up any book, and put it on another shelf where it doesn’t belong.
Eventually a librarian will stumble across it, see that it’s out of place, and pull it off the shelf. Until then, that book is hopelessly lost. It might as well be on the surface of the moon. Amazon S3 - Cross Origin Resource Sharing Support. Why CORS? In order to keep your content safe, your web browser implements something called the same origin policy. The default policy ensures that scripts and other active content loaded from one site or domain cannot interfere or interact with content from another location without an explicit indication that this is the desired behavior.
In certain cases, the developer of the original page might have legitimate reasons to write code that interacts with content or services at other locations. CORS provides the mechanism to allow the developer to tell the browser to allow this interaction. Amazon Web Services Adds Long Requested Web Browser Specification. Amazon Web Services (AWS) added support today for a browser specification that defines ways for apps to allow resources to be accessed by web pages from different domains. The practice is called Cross Origin Resource Sharing (CORS) and has been requested by AWS users for the past few years.
The new service represents another way that AWS automates tasks that developers once had to do themselves. WebRTC is almost here, and it will change the web. Web Real-Time Communication (WebRTC) is a new HTML5 standard framework that enables the sharing of video, audio, and data directly between web browsers. These capabilities open the door to a new wave of advanced web applications. If all goes according to plan, over 50% of all web browsers will support this capability in the next three to four months. This is the most significant step forward in web browser connectivity since 2004, when Google launched Gmail and AJAX was coined. Stack Overflow.
