Styleguide - Style guides for Google-originated open-source projects. Every major open-source project has its own style guide: a set of conventions (sometimes arbitrary) about how to write code for that project.
It is much easier to understand a large codebase when all the code in it is in a consistent style. “Style” covers a lot of ground, from “use camelCase for variable names” to “never use global variables” to “never use exceptions.” This project holds the style guidelines we use for Google code. If you are modifying a project that originated at Google, you may be pointed to this page to see the style guides that apply to that project.
Our C++ Style Guide, Objective-C Style Guide, Java Style Guide, Python Style Guide, Shell Style Guide, HTML/CSS Style Guide, JavaScript Style Guide, AngularJS Style Guide, Common Lisp Style Guide, and Vimscript Style Guide are now available. We have also released cpplint, a tool to assist with style guide compliance, and google-c-style.el, an Emacs settings file for Google style. An Introduction to the C++ Standard Template Library (STL) Introduction The Standard Library is a fundamental part of the C++ Standard. It provides C++ programmers with a comprehensive set of efficiently implemented tools and facilities that can be used for most types of applications.
In this article, I present an introduction/tutorial on the Standard Template Library, which is the most important section of the Standard Library. I briefly present the fundamental concepts in the STL, showing code examples to help you understand these concepts. The article requires and assumes previous knowledge of the basic language features of the C++, in particular, templates (both function templates and class templates). For a detailed description or listing of all the STL facilities, you should consult a reference material, such as Bjarne Stroustrup's The C++ Programming Language, 3rd edition , or Matthew Austern's Generic Programming and the STL.

To start developing on the KDE Development Platform you will need to get familiar with the Qt framework, which is one of building blocks of KDE development. Qt (pronounced officially as cute) is a cross-platform application framework based on C++, that is widely used for developing application software with a graphical user interface (GUI). Thus, it is largely a widget toolkit, but is also used for developing non-GUI programs such as command-line tools and consoles for servers. Besides the KDE Development Platform, Qt is most notably used in Autodesk Maya, Adobe Photoshop Elements, OPIE, Skype, VLC media player, VirtualBox, and Mathematica, and by the European Space Agency, DreamWorks, Google, HP, Lucasfilm, Panasonic, Philips, Samsung, Siemens, Volvo, and Walt Disney Animation Studios.

Since I started using Linux I used GNOME, v1.2 in those times. It has always done what I needed, maybe not perfectly, and not fully, but for the most part. GNOME 3 changed all that. I complained about GNOME 3 since day one, and I discussed with GNOME 3 developers many problems with their rationale about why what they were doing made sense, and I foresaw many of the problems they are now facing. I even started the GNOME user survey, in an effort to make GNOME developers see the light.
I blogged once before about GNOME 3, but only superficially, and even then GNOME developers didn’t take it well. Two years after the first release of GNOME 3, once GNOME developers have had the time to polish the rough edges, it’s time to make the call; GNOME 3 sucks. The purpose of GNOME Before we start, we need to clarify the purpose of GNOME, or rather; the purpose of any software project in general, which is to be useful to the users.

Smarter programmers or safer programming environments? Is the impetus for this article. After I stuck my foot in it (again), saying that .NET and MFC are not frameworks, Paul Watson asked one of the two obvious questions--"what is a framework? " (the other obvious question being, "If .NET and MFC are not frameworks, then what are they?
") Well, Paul's question is an excellent one (and the better of the two, I think), and it led me down this road in an attempt to put my money where my mouth is, as it were. Introduction From my perspective, a framework does several things: it makes it easier to work with complex technologies it ties together a bunch of discrete objects/components into something more useful it forces the team (or just me) to implement code in a way that promotes consistent coding, fewer bugs, and more flexible applications everyone can easily test and debug the code, even code that they didn't write wrappers. A Framework Is... A Wrapper An Architecture. Aaron Greenspan :: Writing. Quora’s Technology Examined. Quora has taken the tech and entrepreneurial world by storm, providing a system that works so fluidly that it is sometimes hard to see what the big fuss is all about. This slick tool is powered, not only by an intelligent crowd of askers and answerers, but by a well-crafted backend created by co-founders who honed their skills at Facebook.
It is not surprising that, with all the smart people using this smart tool, there are many pondering on how it works so well. The NoSQL boffins scratch their heads and ponder such questions as, “Why does Quora use MySQL as the data store rather than NoSQLs such as Cassandra, MongoDB, CouchDB, etc? “. In this blog post I will delve into the snippets of information available on Quora and look at Quora from a technical perspective.

This is the fourth section of the CSS Getting Started tutorial; it outlines how stylesheets interact in a cascade, and how elements inherit style from their parents. You add to your sample stylesheet, using inheritance to alter the style of many parts of your document in one step. Information: Cascading and inheritance The final style for an element can be specified in many different places, which can interact in a complex way. Three main sources of style information form a cascade .
The browser's default styles for the markup language. The user's style modifies the browser's default style. Example When you read this document in a browser, part of the style that you see comes from your browser's defaults for HTML. Part of the style might come from customized browser settings or a customized style definition file. Part of the style comes from stylesheets linked to the document by the wiki server.

We're Playing a Long-Term Game, Says Quora CEO Adam D'Angelo - Liz Gannes. Visiting Quora is striking because it seems to be one of the rare places on the Internet where a diverse group of people come out of the woodwork to try to be smart and thoughtful.
That just doesn’t happen very often. But then, it can be easy to forget to visit Quora, with its random jumble of writings on topics that are interesting but not crucial. As Quora’s co-founder, CEO and also a significant investor, Adam D’Angelo is the driving force behind the site as it expands from Q&A to other kinds of writing. In an interview last week at the company’s new Mountain View, Calif., headquarters, the former Facebook CTO downplayed concerns about the revenue-free Quora growing too slowly, saying he believes he can outlast the faddish companies that come and go by building a high-quality product.
Why harp on growth? Here’s an edited and condensed write-up of the chat: Liz Gannes: How would you describe where Quora as a company is now? What do you use the data for — is it personalization?

Showcase Of Creative Flash Preloaders. Advertisement When it comes to Flash, images, animation, videos and sound effects are often used on large scale. Consequence: in most cases Flash takes quite much time to load and requires a good dose of patience from users. Users know it and are often willing to give a Flash-site some time to load. However, to count on user’s patience, Flash-designers need to inform site visitors how much patience is actually required. If it isn’t done, the latter have no anchor point to estimate how much more time is needed and consequently close the browser window thinking that the site simply doesn’t work properly. Flash-preloaders are supposed to avoid exactly this. It’s important to inform visitors about what is happening. ff0000 informs the visitors about the modules which are loaded on the site.
