720 Common Security Mistakes in Web Applications - Smashing Magazine
Web application developers today need to be skilled in a multitude of disciplines. It’s necessary to build an application that is user friendly, highly performant, accessible and secure, all while executing partially in an untrusted environment that you, the developer, have no control over. I speak, of course, about the User Agent. Most commonly seen in the form of a web browser, but in reality, one never really knows what’s on the other end of the HTTP connection. There are many things to worry about when it comes to security on the Web. Is your site protected against denial of service attacks? Is your user data safe? Can your users be tricked into doing things they would not normally do? Is it possible for an attacker to pollute your database with fake data? Is it possible for an attacker to gain unauthorized access to restricted parts of your site? Unfortunately, unless we’re careful with the code we write, the answer to these questions can often be one we’d rather not hear. We’ll skip over denial of service attacks in this article, but take a close look at the other issues. To be more conformant with standard terminology, we’ll talk about Cross-Site Scripting (XSS), Cross-Site Request Forgery (CSRF), Phishing, Shell injection and SQL injection. We’ll also assume PHP as the language of development, but the problems apply regardless of language, and solutions will be similar in other languages.

691 visualizing.org
Visualizing.org is a community of creative people working to make sense of complex issues through data and design… and it’s a shared space and free resource to help you achieve this goal. Why Visualizing.org? By some estimates, we now create more data each year than in the entirety of prior human history. Data visualization helps us approach, interpret, and extract knowledge from this information. Over the last couple of years, we’ve seen government agencies, NGOs, and companies open up their data for the public to see and use. And we’ve seen data visualization figure more prominently in design curricula, conference programs, and the media. We created Visualizing.org because we want to help connect the proliferation of public data… with a community that can help us understand this data… with the general public. What is Visualizing.org? What can I do on the site? For designers: Visualizing is a place to showcase your work, get feedback, ensure that your work is seen by lots of people and gets used by teachers, journalists, and conference organizers to help educate the public about various world issues Visualizing is a free resource to search for data Use Visualizing to keep up with and be inspired by the latest work from other designers and design schools Learn about new visualization tools, blogs, books and other resources to help your work Everything you upload remains your sole and exclusive property and is licensed under a Creative Commons Attribution Non-Commercial Share-Alike License For teachers and schools: Visualizing is a place to exhibit the collective work of your students, organize assignments and class projects, and help your students find data for their own visualizations We’re working on new tools to help you share teaching material with other teachers As an Academic Partner, your students are eligible to participate in various design competitions – we’re hosting the first Visualizing Marathon in New York in October To learn more, contact Saira Jesani For bloggers and journalists: Visualizing is a resource to find data visualizations about a wide variety of world issues to inform and accompany your own reporting – and it’s easy to embed visualizations and widgets from Visualizing on your own site For conference organizers: As a Knowledge Partner, Visualizing allows you to use data visualizations at your conferences under a Creative Commons License To learn more, contact Saira Jesani For all: Visualizing is a new and fun online resource to learn more about the world in all its complexity and inter-dependence -- and become more comfortable with data and how it can be visually represented How does it work?

506 The Sheldons » Don’t worry, ma’am. We’re from the Internet…
Certo. Resolvi abraçar o papel de uber-geek do grupo, pelo menos no que se refere às coisas menos técnicas. Uma das coisas que mais faço pela Internet é passear por fóruns. De todos os assuntos. Esportes, quadrinhos, cinema, tecnologia, segurança. E, em todos eles, o que mais encontro é….. outros nerds. Como qualquer outro grupo, os nerds têm expressões próprias, referências que só eles entendem. O interessante é que, no caso da Internet, essas referências têm alcance mundial, e se espalham rapidamente. São os chamados Internet Memes. Na verdade, o termo “internet memes” pode até ser usado de forma mais abrangente, significando fenômenos que se iniciam na Internet, e transbordam para a cultura pop, normalmente em função de serem repetidos em diversas mídias. (pequena pausa para cultura. O termo “meme” foi criado por um dos meus autores favoritos: Richard Dawkins. Ele é um ateu proeminente, que no livro “The Selfish Gene” usou o termo “meme” como referência a um grupo de informações culturais) O sitcom responsável pelo nome deste blog, o The Big Bang Theory, volta e meia faz alguma dessas referências, mas ele não é o único. Existem alguns temas que se repetem, principalmente nos fóruns, nos comentários de blog, nos comentários do Digg.com. Normalmente, eles começam de alguma forma estúpida, alguém acha engraçado, repete, e o negócio cresce a olhos vistos (ui!).

370 Welcome, WebM <video>
In February 2007, 1177 days ago to be exact, Opera proposed the <video> element and we published a manifesto for video on the Web. When proposing <video>, we knew there would be two challenges. The first was easy: to get consensus around the syntax. We wanted <video> to be as easy to use as <img>. The second was harder: to find an open and freely-usable high quality video format. The web has always been open and freely-usable; Tim didn’t patent HTML, I didn’t patent CSS and Brendan didn’t patent JavaScript. The big news today is that WebM will join the list of open and freely usable Web formats, and video will finally become a first-class citizen of the Web. This is a big deal, and the day will be remembered in the history of the Web. At Opera, we’re proud to add support for WebM into a Labs build — you can download this build for:

367 60 Minimal and Super Clean Web Designs to Inspire You | Inspiration
A clean and minimal web design is an effective way to convey an image of elegance and sophistication.

332 Web Design Trends for 2010 | Webdesigner Depot
Purists will say that great design is timeless. Yes, in an ideal world, we should ignore trends. Pragmatically speaking, though, there is a lot of value in monitoring and incorporating design trends, especially with regard to websites. Let’s face it: the web changes at a rapid pace. Unlike in other media, design trends on the web are not just driven by aesthetics. Technology is changing that can drastically alter the capabilities of the medium. In 2010, we’re seeing designers continuing to push the boundaries of web design, setting the following clear trends…
