Both accessibility and performance are invisible aspects of an experience and should be considered even if they aren’t explicit goals of the project.

all representations have essentially the same information content. And what we mean by "essentially" allows in fact some wriggle room, and in the end it rests on a common understanding between publisher of the information and quoter of the URI. The sameness we are after is the sameness of information content. That is what is identified by the URI. That is why we say that the URI identifies that conceptual information content, irrespective of its particular representation: the conceptual work. Without that common understanding, the web does not work. Some people have said, "If we say that URIs identify people, nothing breaks". But all the time they, day to day, rely on sameness of the information things on the web, and use URIs with that implicit assumption. As we formalize how the web works, we have to make that assumption explicit.

I'm sticking with the machine-processable languages as examples because human-processable ones like HTML have a level of ambiguity traditional in human natural language but quite out of place in the WWW infrastructure -- or the Semantic Web.

we must either distinguish or be hopelessly fuzzy. And is this bad, is it an inhibition to have to work our way though documents before we can talk about whatever we desire? I would argue not, because it is very important not to lose track of the reasons for our taking and processing any piece of information. The process of publishing and reading is a real social process between social entities, not mechanical agents. To be socially responsible, to be able to handle trust, and so on, we must be aware of these operations. The difference between a car and what some web page says about it is crucial - not only when you are buying a car. Some have opined that the abstraction of the document is nonsense, and all that exists, when a web page describes a car, is the car and various representations of it, the HTML, PNG and GIF bit streams. This is however very weak in my opinion. The various representations have much more in common than simply the car. And the relationship to the car can be many and varied: home page, picture, catalog entry, invoice, remote control panel, weblog, and so on. The document itself is an important part of society - to dismiss its existence is to prevent us being aware of human and aspects of information without which we are impoverished. By contrast, the difference between different representations of the document (GIF or PNG image for example) is very small, and the relationship between versions of a document which changes through time a very strong one.

It demonstrates the ambiguity of natural language that no significant problem had been noticed over the past decade, even though the original author or HTTP , and later co-author of HTTP 1.1 who also did his PhD thesis on an analysis of the web, and both of whom have worked with Web protocols ever since, had had conflicting ideas of what the various terms actually mean.

an HTTP URI may identify something with a vagueness as to the dimensions above, but it still must be used to refer to a unique conceptual object whose various representations have a very large a mount in common. Formally, it is the publisher which defines the what an HTTP URI identifies, and so one should look to the publisher for a commitment as to the exact nature of the identity along these axes.

So instead we introduced the loading spinner on each widget. Nothing is actually any faster, but the whole experience feels more responsive

Simply reducing some CSS transition times from 500ms to 250ms, and cutting others out entirely, made the whole dashboard feel snappier and more responsive.

This means content is served from the nearest possible geographic location to the user, cutting down request latency from as high as 2500ms (in places such as Singapore) to tens of milliseconds

We eventually came up with a compromise solution based on Addy Osmani’s basket.js, using a combination of server-side script concatenation and localStorage for caching. In a nutshell, the page includes a lightweight loader script, which figures out which JS and CSS it has already cached and which needs to be fetched. The loader then requests all the resources it needs from the server in one request, and saves all the resources into localStorage under individual keys. This gives us a great compromise between cutting down the number of HTTP requests while still being able to maintain cacheability, and not re-downloading code unnecessarily when it hasn’t changed. Addtionally, after running a few benchmarks, we found that localStorage is (sometimes) actually faster than the native HTTP cache, especially on mobile browsers.

While these features have connected untold millions and created new forms of social organization, they also come at a cost. Material seems to vanish almost as quickly as it is created, disappearing amid broken links or into the constant flow of the social media “stream.” It can be hard to distinguish fact from falsehood. Corporations have stepped into this confusion, organizing our browsing and data in decidedly closed, non-transparent ways. Did it really have to turn out this way?

The promise of OA lies more in prospects for social success than in the model's descriptive power.

I feel that there is a great benefit to fixing this question at the spec level. Otherwise, what happens? I read a web page, I like it and I am going to annotate it as being a great one -- but first I have to find out whether the URI my browser is used, conceptually by the author of the page, to represent some abstract idea?

We strongly urge you to reconsider your business tactic here and again respect people’s right to choice and control of their online experience by making it easier, more obvious and intuitive for people to maintain the choices they have already made through the upgrade experience.

Let me be very clear: I do not care what the “top highlight” is. In fact, I actively do not want to know what the top highlight is. That kind of information encourages the meme-ification of the web, a world where we care more about pushing one sentence over the “tipping point” into virality than in carrying on a global conversation. It’s American Idol for pull quotes.

To these basic citations, the annotated bibliography adds descriptive and evaluative comments (i.e., an annotation), assessing the nature and value of the cited works. The addition of commentary provides the future reader or researcher essential critical information and a foundation for further research.

Google Annotations Gallery

The Google Annotations Gallery is an exciting new Java open source library that provides a rich set of annotations for developers to express themselves. Do you find the standard Java annotations dry and lackluster? Have you ever resorted to leaving messages to fellow developers with the @Deprecated annotation? Wouldn't you rather leave a @LOL or @Facepalm instead? If so, then this is the gallery for you.

If you want a DIY version of this, try ImageMagick's compare command: compare bag_frame1.gif bag_frame2.gif compare.gif Documentation: http://www.imagemagick.org/Usage/compare/ reply no_gravity 2 hours ago Interesting. And to render the html you can use cutycapt. Which is in the Debian repos too. I just tried it, and this rendered a nice diff of two pages for me: cutycapt --url=http://www.xyz.com/1 --out=1.png cutycapt --url=http://www.xyz.com/2 --out=2.png compare 1.png 2.png diff.png reply easytiger 2 hours ago Now make it a webservice and charge $200/month! reply programmernews3 1 hour ago First part already done: http://archive.is/ reply prottmann 1 hour ago apt-get install the services and use them on my server ;-) reply

Axiom: Opacity of URIs The only thing you can use an identifier for is to refer to an object. When you are not dereferencing, you should not look at the contents of the URI string to gain other information.

Here’s a presentation at the 2013 Personal Democracy Forum that provides a little more context for our project.

Although people weren’t used to scrolling in the mid-nineties, nowadays it’s absolutely natural to scroll. For a continuous and lengthy content, like an article or a tutorial, scrolling provides even better usability than slicing up the text to several separate screens or pages.

There was a point many years ago now when the web looked like it would be for documents. It would be structured and organized, and everything could be linkable.

while e-mail dissolves barriers to the exchange of data, we need another solvent to dissolve the barriers to collaborative use of that data. Applied in the right ways, that solvent creates what I like to call the “universal canvas” -- an environment in which data and applications flow freely on the Web.

Maybe the driver for semantic web data is humans trying to programmatically consume human-readable information, rather than the other way around?

What really needs to happen is for somebody to take a few of the huge publicly available triplestores and write some really compelling reasoning systems on them and demonstrate almost effortless merging across the datasets. Outside of fairly trivial examples, almost all of which are similarly or outperformed by near-enough technologies, really complex reasoners haven't happened.

The cacophony of the crowd erases the past and affirms the present. It started with search and now its accelerated with the now web. I dont know where it leads but I almost want a remember button — like the like or favorite. Something that registers something as a memory — as an salient fact that I for one can draw out of the stream at a later time.
