SafeFrame – thnxz @iab


The SafeFrame 1.0 technology is a managed API-enabled iframe that opens a line of communication between the publisher page content and the iframe-contained external content, such as ads. Because of this line of communication, content served into a SafeFrame is afforded data collection and rich interaction, such as ad expansion, that is unavailable in a standard iframe.

To avoid disruptive ad behavior and the potential security risks of serving ads inline with the page, publishers may choose to have ad content served into an iframe.

An iframe is a sort of mini HTML page within the publisher-hosted page. Using the iframe, ad content is sequestered within the boundaries of the iframe and unable to access any information about the page where it is served. Without access to page content, ad content within the iframe cannot expand, interact dynamically with site visitors, or collect any data necessary in determining ad effectiveness.

The iframe solution protects the publisher, but it also limits ad capabilities and decreases the value of inventory that is restricted to iframes.

SafeFrame’s API-enabled iframe opens a line of communication between webpage code and the ad content in a controlled and transparent way. This communication allows for rich interaction while protecting the publisher’s page from undetected changes that might otherwise damage page integrity.
Some key benefits of SafeFrame for digital advertising include:

Write a Twitter Bot in 5 Minutes – Thnxz to @labnol – Amit Agarwal


Meet @DearAssistant, a Twitter bot that is like a mini version of Siri. You can tweet your questions in plan English and the bot will reply with an answer.

The Twitter bot is internally using Wolfram Alpha so there’s a whole range of questions that it can answer. Here are some questions that people have asked @DearAssistant so far:

  • How many calories are in Diet Coke? (link)
  • When was Mahatama Gandhi born? (link)
  • What is the distance between city A and city B (link)
  • Who directed the film M (link)
  • What is the price of Kindle Paperwhite (link)

Twitter Bot

You can also ask the bot for word meanings, weather conditions, language translation, to convert between time zones, date calculations (how many days until Christmas) and more.

Writing a Twitter Bot – The Basic Ingredients

Writing a Twitter bot is surprisingly simple and you can get one up and running in 5 minutes. It helps if you know little bit of coding (simple JavaScript) but that’s certainly not a requirement for writing a basic Twitter bot.

A bot is essentially a program that is always running in the background and whenever it encounters a command (tweets in this), it processes it (based on the text of the tweeet) and sends a reply to the tweeter in another tweet.

Earlier, you would need a web server to run the bot while the bot itself would be written in languages like PHP, Perl or Python. That’s complicated so we will use Google Scripts to write the Twitter bot and host it on our Google Drive.

There Is No Mobile Internet! // @smashingmag – smashingmagazine.com


By Marek Wolski

A Quiet Change

At the beginning of June, Google published on its Webmaster Central Blog its “Recommendations for Building Smartphone-Optimized Websites.” Its recommendations are that responsiveness — or, where necessary, device-specific HTML — is the way to build websites for today. Both methods are based on all devices accessing one URL, which in Google’s words makes it “easier for your users to interact with, share, and link to…”

Following the recommendation means making most of your Web content accessible across devices. It ensures that each link shared across the Web leads back to the same place and that, irrespective of the user’s device, everyone gets the same design experience. It aims to standardize Web design approaches, but also to standardize user experience expectations.

Shortly after, Apple announced a lot of thrilling updates to iOS 6. One of the least talked about was Safari’s iCloud tabs. This syncs your open browser tabs and allows you to continue browsing from where you left off on another device. Google’s recent version of Chrome for iOS has the same feature. The result? The ultimate cross-media surfing experience, a digital doggy bag.

After many years of Internet people working on standards, technologies and practices to bring about a One Web experience, the two companies made a big push towards making it a reality. We are now a big step closer to, in the words of the W3C, “an Internet where as far as reasonably possible, the same information and services are available to users irrespective of the device they are using.” Well, that is only if website owners and brands get their act together and change their old ways. To do so, they will need to recognize that things aren’t what they seem and aren’t what many are still peddling.

Old Habits, Old Stereotypes

A couple of years ago, mobile devices couldn’t even handle many of the Web’s fundamental standards (JavaScript, for example). But as devices became as powerful as last year’s MacBook, the technology drove a behavioral shift. It wasn’t just early adopters who were using the mobile Web. It was every person and their dog with a smartphone and a 3G connection (around 75% of smartphone owners surf the Web).

Our Mobile Planet - General Smartphone Activities
Image source: Our Mobile Planet.

The line between what is and isn’t Web-enabled is blurring. People don’t see the Internet on their phone or tablet as being the “mobile Internet.” It’s just the Internet. In the words of mobile expert Brad Frost, “mobile users will do anything and everything desktop users will do, provided it’s presented in a usable way.”

For the last few years, across categories, mobile experience benchmarking studies have been filled with recommendations to broaden and deepen the content available. Users are searching more and longer for information that currently isn’t available on mobile or even tablet devices.

Mobile Site vs Full Site
Image source: Strangeloop.

This desire for information is prevalent and strong enough that many opt for a less than optimal visit to the “full site” in order to access more or other information. The fact that almost a third of mobile users are prepared to endure poor navigation, slow loading times and no touch optimization really underscores the presence of this fundamental behavior.

Multi-Device World: about design and more, and more… // @smashingmag / @flipthemedia


Thnx to smashingmagazine.com and flipthemedia.com

When I think about where we are with the Web in comparison to other media in history, pinpointing it is really hard. Is it like when the Gutenberg Press was just invented and we’re experimenting with movable type, or are we still embellishing pages and slavishly copying books by hand?

By 

 

Our knowledge of building digital things changes rapidly, taking us from newborn to adult and back again every couple of years. It’s both exciting and frustrating, because just when you think you have it all figured out, it completely changes. But if you’re like me, learning something new keeps things interesting.

So, it seems pretty normal that our methods of designing and building websites are questioned every so often. The argument to ditch design apps (or to drastically minimize the time spent in them) and go straight to the browser has popped up a lot in the past few years and then quite recently. It’s obvious that our digital world and, by proxy, our design process are in a state of transition. And they should be: considering design in the context of your materials and goals is always important.

I tend to shy away from prescriptive approaches. Most decisions are framed by our experience, and, as humans, we’re continually drawn to and seek out what we already believe (known as “confirmation bias”), ignoring the rest. So, I strive to keep that in mind whenever listening to advice about how things should be done. We’re all navigating the same changing landscape here. What many designers recommend is the right answer for them and not necessarily the right answer for you, or your client. As Cameron Moll more eloquently states:

“You know your circumstances, your users, and your personal preferences best. And if that means responsive web design — or design methodology or todo app or office chair or whatever — isn’t the right choice for you, don’t be ashamed if you find yourself wanting more, or at least wanting something else.”

That’s exactly how I feel right now. A lot of the explorations into Web design lately have been looking for the best ways to optimize an experience and to make it as flexible as possible across devices. These are important issues. But what about the design principles we’ve proven and iterated on through a variety of media? How can we apply what we’ve learned about design so that it can be utilized in an appropriate way to create websites in this multi-canvas world?


Typographic Design in the Digital Domain” with Erik Spiekermann and Elliot Jay Stocks

In an interview with Elliot Jay Stocks, legendary typographer and designer Erik Spiekermann explains how he finds it funny that designers today complain about limitations in designing for mobile…

by 
1. Technology and use trends

  • Digital options increase every day
  • Fluidity allows you to reach people through all the different methods available
  • Some devices actually create new data, which yield new insights (i.e. FitBit, Fuel band, etc. This idea will also be interesting for toys.)
  • Network speeds increasing (huge difference from 3G to LTE)
  • With the decreased price of cloud storage, sharing content across devices is easier (shared experience)
  • Content management systems drive the consumer experience and should be integrated into the foundation of your platform

2. Types of connected experiences

  • Synchronized: for example, the eReader let’s you make notes and brings you back to where you last stopped, no matter the device. Evernote allows you to share information and access documents from different locations and devices.
  • Adaptive: content adapts to your current device. This could mean apps for the device you want to target or responsive websites. It’s important to consider how the customer will engage on a device and what information you need to share.
  • Complementary(second screen): people interact with content at an event or with others experiencing an event. A lot of networks are investing in second screen platforms. 80% of people with tablets watch television with a second screen in front of them; an opportunity for networks to build deeper experiences for customers.
  • Device shifting: people start searches on mobile/tablets and finishing them elsewhere, shifting seamlessly from device to device. Consider content and context of each device.  For example, when searching for cars, on the phone you might want to show visuals, basic information, and location-based results, while on the PC you have expanded information, but don’t focus on location-based information specifically.

JavaScript-Turbo: Head.js Speeds Up Your Website
By Denis PotschienPosted in Javascript

Complex websites would not work well without JavaScript. Often there are several scripts residing in the head of your HTML document. The more you embed, the slower your website, potentially. Head.js is a JavaScript tool that calls itself the only script you need. We have put it to the test and found out that Head.js can really boost the performance on websites with several scripts. The more scripts you call in the head the higher the effect Head.js can provide.

Pixabay: More Than 40,000 Completely Free Photos And Illustrations
By Dieter PetereitPosted in Freebie

As designers we are always on the hunt for good pictures. Noupe certainly needs fitting imagery now and then and even more often. That’s where photo-services, stock image providers and the like come into play. There are big marketplaces, offering you high-grade imagery at more or less affordable rates. Then we find repositories with free usage policies but varying licenses, which at times are not easily comprehensible. I have certainly been in trouble with this kind of mine-seeking. Pixabay, a fresh repository with a quickly growing selection of excellent imagery, is different, dead-simple. All the pictures are free, no license conditions apply. Pixabay delivers pure public domain photos.

bog.bancopopular-e.com | Conoce el nuevo etiquetado de neumáticos: más ahorro de carburante y más seguridad


 

por Equipo Social Media

Desde el 1 de noviembre, una nueva reglamentación de la Comisión Europea exige que en los neumáticos que se vendan dentro de la UE –excepto los recauchutados, con clavos, off-road, neumáticos para competición y neumáticos para vehículos de colección– tiene que figurar una etiqueta con tres características esenciales: consumo energético, seguridad en la frenada y el ruido que producen al rodar.

El etiquetado es similar al de los electrodomésticos, en el que la letra A califica a los más eficientes y la D a los que más electricidad consumen. En este caso, la clasificación cuenta con 7 apartados –de la A a la G–, que orientan al consumidor para que conozca la calidad de lo que está comprando. Sin embargo, no aporta cifras exactas de lo que supone equipar el vehículo con una u otra clase de neumático.

Esos datos los aporta un estudio realizado conjuntamente por la compañía Michelin y el RACC, el mayor club del automóvil de España >>>>  Sigue leyendo

Anonymous sostiene que Wikileaks los “traicionó”


Infotechnology

La organización de hackers lanzó un comunicado apuntando contra la agrupación de Julian Assange. “No nos arriesgaremos más a ir a prisión para defender a sus enemigos”, sostuvieron.

“No soy yo, sos vos”, le podrían haber dicho desde Anonymous a Wikileaks. Es que lo que supo ser un matrimonio feliz hoy se convirtió en un polémico divorcio. El detonante fue la decisión de la organización de Julian Assange deutilizar un “muro de pago” para ingresar a sus documentos. Desde la agrupación de hackers sostuvieron que “ya soportaron demasiado” y que “fueron traicionados”. “La conclusión que hemos llegado es que Anonymous no puede apoyar más a la lo que Wikileaks se transformó”, sostuvieron en un comunicado.

anonymous
Además, aseguraron que desde hace unos años que “están preocupados” por el estado de Wikileaks, ya que sostienen que pasó de ser una agrupación enfocada en la libertad de la información a poner sus ojos solo en su líder y el afán por conseguir dinero.

Actualmente, el muro de pago que aparecía para ingresar a ciertos documentos fue dado de baja. En un comunicadofirmado por Assange, la organización explica los nuevos archivos relacionados a las elecciones de Estados Unidos que habilitaron en su sitio y señalan que “todas las donaciones servirán para pagar los costos de infraestructura, como los legales por los bloqueos financieros que sufre la organización.  Sigue leyendo

Web browser showdown: Which Windows app is really the best? | via pcworld.com


 

Your Web browser is probably the most-used application on your PC. You check your email in it, you write in it, you collaborate with coworkers in it, you use it to watch cat videos. With so much at stake, you need a browser that works well for you.

But which one is the best? We put the three major Windows browsers—Google Chrome 21, Microsoft Internet Explorer 9, and Mozilla Firefox 15—through their paces and crowned an overall winner.

Browser performance

When we looked at the browser contenders previously, we concluded that all the major browsers loaded webpages at similar speeds.

But many new Web apps and services rely heavily on HTML5 and JavaScript, so the browser makers have been spending a lot of development time making sure that their programs render such apps and services quickly and efficiently.

To gauge how well browsers handle HTML5 and JavaScript code, we subjected Chrome, IE, and Firefox to the Sunspider JavaScript benchmark and to the WebVizBench benchmark for HTML5. In addition, we tested on a PC with switchable Nvidia graphics hardware to see how each browser exploited the extra processing horsepower in the graphics card.

Our test PC was an Acer Aspire Timeline Ultra M5 laptop with a 1.7GHz Intel Core i5 processor and 6GB of memory. The switchable graphics system consisted of an integrated Intel HD Graphics 4000 chipset and a dedicated Nvidia GeForce GT 640M graphics card with 1GB of video memory.

In our WebVizBench HTML5 benchmark test, Chrome and IE 9 saw large increases in performance when we switched to the dedicated graphics card instead of the integrated graphics chip.

Chrome achieved an average score of 5502 when we used the integrated graphics system, and hit an average of 5825 when we used the Nvidia graphics card. IE 9 came in second with average scores of 4797 and 5642, respectively; Firefox finished third after posting average scores of 4492 and 5600. Notably, Chrome did almost as well on this test using the integrated graphics hardware as the other browsers did using the more powerful Nvidia graphics card. So if your PC has a weak graphics card, you’ll probably get better performance from Chrome than from Firefox or IE.

Our tests for JavaScript performance were less conclusive, with all three browsers rendering the benchmark’s JavaScript code within 15 milliseconds of one another. Internet Explorer 9 eked out a narrow victory, completing the Sunspider benchmark in 200 milliseconds. Chrome 21 finished in second place at 206 milliseconds, and Firefox 15 rounded out the three at 214 milliseconds.

Winner: Google Chrome. Browser performance will vary some depending on your PC, but Chrome was a solid all-around performer in our testing.

Scientists Convert a 53,000-Word Book Into DNA


digital-dna-600by  | Mashable.com

In a scientific first, Harvard University researches successfully transformed a 53,426-word book into DNA, the same substance that provides the genetic template for all living things. The achievement could eventually lead to the mass adoption of DNA as a long-term storage medium.

Published Thursday in the journal Science, the experiment aimed to demonstrate the viability of storing large amounts of data on DNA molecules. Since the data is recorded on individual nucleobase pairs in the DNA strand (those adenine-guanine/cytosine-thymine pairs you may be straining to remember from high school biology), DNA can actually store more information per cubic millimeter than flash memory or even some experimental storage techs, IEEE Spectrum reports.

The difficulty is in the translation — both to DNA and back again (summarized in the diagram below). The researchers started with the book’s content, which included the text as well as 11 images and a javascript program, and converted it to binary code. Then they assigned every 0 and 1 a nucleobase.

Great jQuery plugins for fresh websites


One can only imagine how tough it was to practice web design back when everything seemed so new — during the days of Netscape Navigator and Microsoft FrontPage. Looking back, it seems like such an archaic time in the history of web design. It was almost impossible to design something of supreme and intelligent creativity. Back then, you were seen as creative if you had an awful flashing background or colored scrollbars.

There wasn’t a ton of flexibility really when it came down to the nitty gritty of design. Many of the layouts were the same and mimicked what was seen in magazines and newspapers. I mean just think about it: not too long ago we were able to finally figure out a way to use decorative fonts online. Beforehand, it was all Arial, all Verdana and all Times New Roman — in 2012, can you imagine living that life?

Tables were the norm and those weren’t too flexible. Speaking of flexibility, how did we ever live without responsiveness? If you wanted to design a website a while ago, you pretty much were boxed in to work with what you had. No one complained then, but thank goodness for progressive technology.

Now…
Fast forward to now, and we can pretty much design anything the way we want to, in whatever we want to. These types of things shouldn’t be taken for granted, but as new generations of designers and developers enter this realm, it pretty much is. I mean, just a few months ago, we were finally able to use style sheets to create rounded corners — how quick do we forget? Sigue leyendo
