OpenSocial – Podcast test

Posted by Rafa on November 2, 2007


Google has just launched OpenSocial, an open API that allows to develop programs to access to multiple social networks at the same time, like MySpace, LinkedIn, Friendster and many others.

Details on the audio podcast attached (let’s see how it works!).

Summary of timing dedication

Posted by web20evolution on October 26, 2007

This is the summary of dedication of the web20evolution team:Summary of timing dedication

As per results, most of the time was dedicated to reading, mainly to get information about the different topics to be published on our blog. It is curious the amount of time team dedicated to think. This may be a misunderstanding, and may have been mixed with timing dedicating to understand and interpretate the readings. Probably a thing to improve next time is to interact with others and participate more actively on comments from others. Almost all posts have less than 4 comments, and discussion helps to make blogs richer and more useful.

FOSS (Free and Open Source Software) is an alternate and almost equivalent term to free software, the term created created by Richard Stallman,  and I think it’s worth considering it as part of the Web 2.0 world.

As in free software, FOSS gives the user the right to use, understand, change and redistribute the software (for free). The use of FOSS has increased in the last years, as the free-software community has created software in many areas, including operating systems (see GNU/Linux), databases and a big variaty of applications.

Some questions come to my mind regarding FOSS:
1) How can we make money with FOSS ? Can we make money by supporting and installing free software ? Anyone can access and download free SW, but installing and supporting it is different history.
2) Why do developers spend hours writing code and then give it away ?
3) What is the economic impact or FOSS ? FOSS is increasing a lot, and some studies says that the existing base of FOSS applications is worth Euro 12 Billion. This is a lot of money, and it threatens current SW companies.

What is clear is that FOSS is an important technological, social, and business phenomena, and probably will become one of the biggest change in the industry.

CC needs support

Posted by Rafa on October 21, 2007

Creative commons (CC) is a corporation that defines different options between copyright and no rights at all in order to distribute content through the network. So, a key aspect in web2.0 since web2.0 is related to share information, included content created by ourselves.

CC now is asking for donations to survive. They already got 140K$ of the targeted 500K$. CC licensing is important, and is more and more used, since it can be an alternative to the tax (royalty) charged by the Spanish government through the so-called SGAE’s canon.

(For non-Spanish people, see example of the SGAE’s canon here).

I, Cyborg?

Posted by web20evolution on October 19, 2007

A cyborg is a human who needs a piece of metal to solve a problem in his or her body. At least, that’s a classical definition of a cyborg.

However a cyborg is no longer something from science fiction but something real. For example, if I put a surveillance camera up somewhere, it’s like a third eye and it doesn’t even sleep. So there is no metal in my body, but in a sense, I’m still a cyborg. However, if my metal extension need to work when I’m asleep, this means that some processing outside of my mind needs to go on as well. This is like having a piece of my brain in a computer somewhere. Or on the internet. There will be more and more cyborgs now that we have Web 2.0. Web 2.0 can function as a prothesis for many function, for example, as a database that keeps our knowledge.

If Web 2.0 is the prothesis for the human being, we can analyze the multiple prothesis we can use today or even others use today. Some examples are blogs, applications like flickr, del.ici.us or even search engines, like google. Simple prothesis though, but they may evolve in the future.
What’s next ? To become more advanced cyborgs, as Web 2.0 evolve to more advanced and intelligent applications, is the next step. New intelligent search engines, databases, a sensor network, things related to Web 3.0, … That might become tomorrow’s prothesis.

The odds are that Internet users can be starting to “FEEL” like a cyborg. Perhaps, we are starting to think like the machines. The network is changing, and the users too. The humans sometimes think ¿who are we?,and actually we should think, who am i? (into the network?). Like a cyborg, the users are integrating into their mind schemas, the different processing information modes through the network. In fact, we have differences in this behaviour, depening on if i am a man or a woman, and for this reason, the Cyber-Feminism or Cyber-Male Chauvinism concepts, are starting to be more powerful in the Web. These kind of things start to be each time more common in internet, and not only in our daily life. We should think how it is affecting to our private and personal life.

Nanoblogging (or microblogging) are web pages where users create networks and communicate between them using short messages. Most famous one is Twitter, although the reason for my post today is that Jaiku (probably the second most famous nanoblogging site) has recently been acquired by Google.
As you know, Blogger was acquired by Google some years ago, and now they have acquired Jaiku.
To be honest, although I do have a Twitter account, I do not use it (my life is too boring to be shared every minute 🙂 ). But with the Google acquisition probably nanoblogging sites will become as famous as blogging, and with the mobile integration they can even be a similar revolution as the SMS message were.

Active content = less accessibility, more misery

Posted by iljitsch on October 14, 2007

A while ago, I wrote this rant. Since web 2.0 is also often used in conjunction with AJAX (asynchronous javascript and XML) that powers all these neat tricks that can make web applications behave (almost) like real, local applications, I thought this might apply somewhat to our discussion here. So:

Embedded programs that are supposed to enhance our content are in fact making it less secure, less reliable, more expensive to create, promote monocultures and limit consumers’ options. This problem is most apparent on the web, but it’s permeating elsewhere as well.

Phishers trick people into revealing sensitive data by making the user believe he or she is dealing with a legit outfit. For instance, when you hover your mouse pointer over a link, normally, you’ll see the URL the link points to. But with some scripting, it’s possible to display something different. That’s bad, but it gets worse. It’s easy to scan an HTML page to determine if there are any undesired URLs in it. But if there is a script attached to that page, this is no longer possible, because the script can be programmed to construct the unwanted content when it’s run.

Less reliable: if you have a browser display an HTML page with some illegal HTML in it, in almost all cases, the result is usable to some degree: the browser ignores the HTML it doesn’t understand and goes on to render the rest. But with a JavaScript program, if there is one statement or function that the browser doesn’t understand or implements in a way that wasn’t expected by the programmer, and in most cases, the program can’t be executed at all or it fails to function to any useful degree.

Because programs are so fragile, it’s necessary to test them in all environments where they’ll have to function. This is why it’s so hard to surf the web with a browser other than the two or three most popular ones: content creators don’t test their scripts on these browsers, the content doesn’t work, and people switch to Internet Explorer or Firefox.

When DVDs first appeared, only the FBI warnings were unskipable. But having the ability to restrict the use of certain DVD player functions, DVD creators soon started making previews and ads unskipable too, sometimes even forcing users to go through menus to select different soundtracks or subtitles.

Please stop this proliferation of active content, for the most part, it’s not making our lives better.

Predictions about the web accesibility & Web 2.0

Posted by Rosa Delgado on October 13, 2007

I have been reading about web 2. and web accesibility, and i have done a summarize about some predictions and conclusions:

There are three major factors that will shape web accessibility in the very very short future: AJAX, user generated content and WCAG 2.0. The increased prominence of these factors could lead to some of the following:

Accessibility will become less and less guideline-driven
With the advent of new technology (such as AJAX), and the technology-neutral and vague nature of the new W3C guidelines (WCAG 2.0), accessibility is becoming less and less guideline driven. This means that employing accessibility experts is going to become more and more important for organisations as interpreting these guidelines correctly will become more and more difficult.
Alternative accessible versions will become the norm
Historically speaking, separate accessible versions were frowned on for both ethical and business reasons (see Separate text-only version? No thanks!13 for more on this). However, for the first time usability and accessibility are coming head-to-head with each other and rich interactive interfaces often can’t be made fully accessible. In this instance, a separate version will have to be provided (but only after all other routes have been exhausted).
User generated content is likely to offer poor accessibility
Content created by users is becoming more and more commonplace on the web. This kind of content is being created at such a rapid rate that it’s going to be impossible to police it for accessibility.
JavaScript, PDF & Flash will no longer be thought of as ‘evil’
In WCAG 1.0, web managers and developers were basically told that their websites shouldn’t rely on any of these three technologies. WCAG 2.0 on the other hand doesn’t stipulate this, and rightly so as most assistive technologies can now support these technologies.
