Chrome Release Channels Chrome supports a number of different release channels. We use these channels to slowly roll out updates to users, starting with our close to daily Canary channel builds, all the way up to our Stable channel releases that happen every 6 weeks roughly. Channels Windows 64-bit All channels may be run in parallel -- they install into distinct directories and use dedicated User Data directories. Windows 32-bit Mac Android Linux How do I choose which channel to use? The release channels for chrome range from the most stable and tested (Stable channel) to completely untested and likely least stable (Canary channel). What should I do before I change my channel? Back up your data! Before you switch, you should make a backup of your profile (bookmarks, most visited pages, history, cookies, etc). Make a copy of the User Data\Default directory (for example, copy it to 'Default Backup' in the same location). ~/.config/google-chrome/Default Reporting Dev channel and Canary build problems

50 Kick-Ass Websites You Need to Know About It's time to update the entries in your browser's links toolbar. But with recent estimates putting the size of the internet at well more than 100 million distinct websites, it's getting harder and harder to get a handle on all the great stuff that's out there. That's why we've compiled this list. And unlike some lists you may have seen, which try to name the very "best" websites, but end up just telling you a lot of stuff you already know, we've chosen instead to highlight 50 of our favorite sites that fly under most people's radar. You might have heard of some of these sites, but we'll bet you haven't heard of all them. See What Can Be Done with 4 Kilobytes If you’re any kind of nerd at all, you probably know about the demoscene, where talented programmers create complex videos rendered in real-time, stored in incredibly small files. But what if you just want to see what all the fuss is about without actually downloading and running an executable?

Value at Risk (VaR) for Algorithmic Trading Risk Management - Part I - QuantStart Estimating the risk of loss to an algorithmic trading strategy, or portfolio of strategies, is of extreme importance for long-term capital growth. Many techniques for risk management have been developed for use in institutional settings. One technique in particular, known as Value at Risk or VaR, will be the topic of this article. We will be applying the concept of VaR to a single strategy or a set of strategies in order to help us quantify risk in our trading portfolio. VaR provides an estimate, under a given degree of confidence, of the size of a loss from a portfolio over a given time period. In this instance "portfolio" can refer to a single strategy, a group of strategies, a trader's book, a prop desk, a hedge fund or an entire investment bank. For example, a VaR equal to 500,000 USD at 95% confidence level for a time period of a day would simply state that there is a 95% probability of losing no more than 500,000 USD in the following day.

The term ‘geek’, once used to label a circus freak, has morphed in meaning over the years. What was once an unusual profession transferred into a word indicating social awkwardness. As time has gone on, the word has yet again morphed to indicate a new type of individual: someone who is obsessive over one (or more) particular subjects, whether it be science, photography, electronics, computers, media, or any other field. A techie geek is usually one who knows a little about everything, and is thus the person family and friends turn to whenever they have a question.

Developing Backbone.js Applications - By Addy Osmani (@addyosmani) Available free for open-source reading below or for purchase via the O'Reilly store. Pull requests and comments always welcome. Prelude Not so long ago, “data-rich web application” was an oxymoron. Traditionally, web applications left the heavy-lifting of data to servers that pushed HTML to the browser in complete page loads. Think of the Ajax shopping cart which doesn’t require a refresh on the page when adding an item to your basket. The rise of arbitrary code on the client-side which can talk to the server however it sees fit has meant an increase in client-side complexity. Thankfully, there are a growing number of JavaScript libraries that can help improve the structure and maintainability of your code, making it easier to build ambitious interfaces without a great deal of effort. Begin with the fundamentals, work your way through the exercises, and learn how to build an application that is both cleanly organized and maintainable. Target Audience Credits <!

The Deep Web: Everything You Wanted To Know & More A while back TFOT wrote about a new form of journalism that was based on content dug up from the depths of the deep web. Vocativ, the emerging news site that delves deeper prefers to reach farther than search engines and mainstream media choose to go for their content. As a matter of fact, while Google seems to have its hand in everything these days and appears to be the “be all end all” go to place for searching information, it (and fellow search engines) only scratch a mere 4% of all web content. This means that the other 96% of www content remains uncrawled and “invisible”. Due to the anonymity provided by the “deep web” it has been known to be used for nefarious activities such as the “ebay of illegal drugs” the silk road. We would like to take you down the rabbit hole and shed light on this deep and invisible web. Deep Web Infographic (Credit: and

Anti-Patterns in Python Programming - Constantine Lignos This page is a collection of the most unfortunate but occasionally subtle issues I've seen in code written by students new to writing Python. It's written to help students get past the phase of writing ugly Python code and understand some of the most common idioms. The simplifications employed (for example, ignoring generators and the power of itertools when talking about iteration) reflect its intended audience. There are always reasons to use some of these anti-patterns, which I've tried to give those where possible, but in general using these anti-patterns makes for less readable, more buggy, and less Pythonic code. If you have comments or wish to use this work in way other than what the license allows, feel free to get in touch with me by e-mail. The use of range Programmers that are new to Python love using range to perform simple iteration by applying it over the length of an iterable and then getting each element: for i in range(len(alist)): print alist[i] Why do this?

Fantastic Micro-Frameworks and Micro-Libraries for Fun and Profit! Full Stack Python Read Your First Meteor Application | Leanpub 1 Introduction There’s a lot to love about the Meteor JavaScript framework: You can build entire web applications with nothing but JavaScript. Your applications are real-time by default, similar to desktop applications. There’s a large and helpful community to help you along the way. Meteor is also relatively easy to learn, making it a great for web development beginners who might have never built a web application before but still want to make software on the cutting edge of what’s possible on the web (and hopefully you fit somewhere on that spectrum). It’s these reasons that, quite quickly, led me to becoming a Meteor fanboy. I’ve read almost every tutorial and watched every screencast out there. Because while there are great resources for learning Meteor — Discover Meteor and Evented Mind are the big ones – and while many of these resources are meant for beginners, I still found myself bouncing between multiple resources before certain Meteor concepts were able to “stick” in my mind.
