  • Adding a RSS feed to your blog

  • Adding rss for a blog to your reader

  • subscribe

  • Link is on the left column

  • Another option is from a site

  • Wait a secondANYONE can edit a wiki? Yup.In Wikipedia when there are problems.

  • PodcastsSyndicating audio content, prompting some folks to compare it to an audio version of a blogUses RSS feeds, but it puts an audio component in the field

  • Intellectual Property rights and copyrightConstitution, Article 1, Section 8The Congress shall have powerto provide for the general welfare of the United States To promote the progress of science and useful arts, by securing for limited times to authors and inventors the exclusive right to their respective writings and discoveries;(emphasis added)

  • What has copyright become?Licensing is replacing copyright in the digital ageMoving long standing common law or constitutional rights into the arena of person to person business transactions, where these rights no longer apply. Examples, international arena, increasing time before work enters the public domainFair use is disappearing

  • Public domain: Why should we care?Whats part of Public Domain?Still isWasAirWaterSunlightLandNumbersGodIdeas & Facts*Resources freely available, without permissions or fees needed, and no tracking of what you read or use - all for society to do what they want with them.

  • Importance of Public DomainCommon Heritage (philosophical)New Knowledge incorporates Old (progress)Derivitative works rely on pre-existing works (creativity)Social Commentary (free speech)

  • Lengthier Copyright Means:http://www.copyright.cornell.edu/training/Hirtle_Public_Domain.htm



  • What this meansDismantlement of the public sphere in general - controlling social/political commentary & satire.Criminalizing acts that might impede digital commerce.Controlling access to older information (our history).Makes the Internet a commercial venture, not for production of ideas.Diminishment of exploration & experimentation.Challenges Democratic values (that anyone can be a creator)

  • How to find them

  • To listen, just double click

  • How to make a podcast:First you'll need to use software to record your own audio file. Youll also need something which allows MP3 exportation.Once your audio is recorded you'll need to create an RSS feed file. 4) Once your audio and RSS files are completed you'll need to upload both of them to your server/website.

  • Equipment you can use to make one

  • This is what a professional podcast site looks like

  • Once you have a file, upload to iTunes

  • File sharing What is it?How is it useful?Examples?

    This is a web based diary.

    The term "weblog" was coined by Jorn Barger on 17 December 1997. The shorter version, "blog," was coined by Peter Merholz, who, in April or May of 1999, broke the word weblog into the phrase "we blog" in the sidebar of his weblog

    I like to think of it as a diary that happens to be online. It is not very easy to search, like your diary with the lock and key werent. You can read from start to finish, but short of flipping the pages, you cant get to what you want very accurately.

    Many of them have these elements in themHere is what all of those elements might look like:Here is a very popular individuals blog, not a corporate one. According to Technorati, which ranks blogs based on ''net attention,'' or the number of people who are linking to them, Ms. Klein's blog has a rank of 2,132, meaning that of the world's more than 13 million blogs, there are only 2,000 or so with more inbound links than hers. ''That would put her in the top 1 percent of all bloggers,'' said David L. Sifry, the founder and chief executive officer of Technorati. (The top 100-ranked blogs tend to offer news and political commentary; single-subject or niche blogs like Ms. Klein's, even the most popular, are generally further down the list.)

    If we applied all those elements from the wikipedia article, Id guess the following.Post Date - date:time the post was published Category - category the post is labeled with (can be one or more) Title - main title of the post Body - main content of the post Trackback - links back from other sites **important**Comments - comments added by readers Permalink - the URL of the full, individual article **important**Footer - usually at the bottom of the post, often showing post date/time, author, category, and stats such as number of comments or trackbacks.LinuxApacheMySQLPHPAll robust open source products-Diagram by Peter VerreyThis is one we could editHow many folks have a blog? How many folks have seen one being edited?

    How to edit it on blogger,,,,if theres time/interestGo to my blog

    Now, if theres a blog that you like, and sometimes the person posts 3 entries one day and then not another one for weeks. You, the loyal reader, check every day for some new pearls of wisdom. What if there was a way that you could be notified, on your phone, by email or by checking a single web page of just whats new on your favorite sites?

    Here are the different symbols used to indicate that an RSS feed is available for the site. These symbols are a whole other discussion themselves. Why is this such a popular application? What are other applications?i.e. buying cars, EAD encoding for primary resources (UVA had a copy of the Declaration of Indep, Montecello has a bunch of letters written at that time, the Philadelphia library has other materials, how will you find it all?)

    How do you use these things? this creates a mini-database that allows for the gathering and distribution of news. You can go one of two ways with this application, either

    a) allow you to see what's new on a site that you monitor for news and informationi.e. New York Times headlines, your favorite blog, the MySpace promoter who'se parties you like going to, books you want to read in your library, podcasts, images: flicker,anything that updates regularly.

    b)allows folks who are reading your site/blog/regularly updated internet based thing to monitor what is new with you. The economic implications for this should be obvious, as it can increase traffic to a site, without expecting someone to actually come to your site every day.

    You can "drive traffic by letting others know what you are doing. The difference is now we can notify others not just of a new site, but of new stories -- new activity on our site"- O'Reilly Network's President and CEO Dale DoughertyHow these work is based on Extensible markup language, there is lots of documentation about what is needed and whats optional here is one such page:http://blogs.law.harvard.edu/tech/rss#requiredChannelElements

    Need the title and a link, the description is optional

    You can then make an RSS feed for something like your blogThis was generated by an automatic RSS generator.here is the title, link and description tag

    A channel can contain any number of items MUST have either a title or a descriptionnothing else is mandatoryHere is an item recordWith a title, link and description tooYou can just add a bookmark for this or you can use a readerAdding a RSS feed to your blog can be as easy as thisIn blogger, log in, got to settings > sit feed

    3rd party software does this as wellCan program it as well (ask corey about this?)

    READING other RSS feeds is usually done by setting up a RSS reader. There are lots of them.Here is one, Bloglines, which I like because it is a web based RSS reader, instead of being platform specific.Allows you to look at just what is new on a particular site. Here is an example of a search at a library with an RSS feed. The search is for books in computer science.

    Lets add the RSS feed we just created from our blogAdding a new RSS feed is easy.Go to Add and then find a feed you want to see and copy it into the search boxMore commonly, when youre on a favorite/fabulous web site, use the XML, RSS button to add to your Reader.Select sub bloglines - For Daily show videoClicking on that sub bloglines button gives you this screenHere are the videos added to the left under feeds, click on the link and youll get the content on the right

    You can also bookmark the pages you want to keep track of. Some of the RSS readers will send you an email with the new information.Most collaboration software resembles bad filing systems. It enforces a structure that's too rigid, making assumptions about how people want to collaborate, and then forcing them to work that way.Wikis occupy the opposite end of this spectrum, offering the ultimate in flexibility: a blank page. Invented by Ward Cunningham as a way to quickly and collaboratively publish software design patterns on the Web, Wikis have sprouted up all over the Web and even on corporate intranets. Despite its philosophy of openness and its catchy name, the Wiki has remained one of the best-kept secrets on the Internet.-from http://www.webtechniques.com/archives/2001/09/book/

    What does it mean?Patrick Taylor, an etymologist, has written the following definition of wiki for the 2004 American Heritage Dictionary.[wiki, abbreviation of WikiWikiWeb, name given in 1995 by American computer programmer Ward Cunningham to his new code, which permits the easy development of collaborative websites whose content can be edited by anyone with access to them. From Hawaiian wikiwiki fast, speedy, reduplication of wiki fast, akin to Tahitian viti and vitiviti, deft, alert, well done, both from Proto-Eastern-Polynesian *witi. Also,, "Wiki Wiki" as a bus line at the Honolulu International Airport.

    In addition to corporate uses, it can be used to make anything collaborative. Think of the Wikipedia, instead of having a publisher pay people to write articles for something like the World Book encyclopedia you allow anyone to write, edit, and add things to a site.Other uses?replaces a bulletin board and also allows people to create a web based resource together. Seems to really use the power of hyperlinking in a new and unusual way.Group/collaborative story,I.e. a murder mystery***There is arguably greater use of wikis behind firewalls than on the public internet.*****In 2005, the Los Angeles Times experimented with using a wiki in the editorial section of its web site. The Wikitorial project was quickly shuttered as vandals quickly defaced it and features to help distribute administration of the site had been disabled.

    Lets look at how some work, lets edit an entry in WikipediaLike the blog, but usually more complex, usually in the 3rd step?-Diagram by Peter Verrey

    [Also on darkwing, cant use MySQL, so had to use a wiki that employed PERL, would that go in the purple round thingy that represents the DB be Database (Perl)?

    A more complex application of this would be something like Blackboard, where the purple round thingy representing the database, would be Oracle, not MySQL?]

    You can set up a wiki of your own on your darkwing account. This isnt particularly easy to do, I had the help of someone in the computing center. And, because I didnt want to maintain the server, this one uses Perl-can add pages-add content-can delete pages

    Lets edit this page Add what youd like and youll get.Now, its changed.

    Other uses?-professors from different universities, and different disciplines applying for an National Science Foundation grant use oneLets update the UO page on wikipedia-add an external link to the list of departments[[ ]] with the URL then a space and then the name of the link as you want it to appear!This is what it looks like after you save itFor instance, many people are amazed that the Wiki lets anyone edit pages. The tacit assumption is that if there is no lock, humans will naturally break in and wreak havoc. However, while this is true for some people, most simply don't go around seeking unlocked houses to rob and vandalize.According to the authors, most Wikis haven't had a problem with vandalism. When you think about it, this isn't so surprising. There's no challenge in breaking into a site with unlimited access, and what interests most hackers is the challenge.

    http://en.wikipedia.org/wiki/Wikipedia:Protected_pages#Pages_protected_due_to_edit_wars_or_vandalismAdding a new page to the wikipedia is really easy start by clicking on the edit mark, which gives you this view add the [[ which gives you The double [[ make the line a link.. But, until theres a actual page, the item will be red. If you click on it, youll be asked if you want to start a new pageHeres your blank page, add text to the boxHeres the text that I want to appearThis is what it looks like publishedWhat is the technology behind this?A Podcast is just an audio file that is syndicated via an RSS feed, that you download and listen to with your computer or a portable device such as an iPod.What makes it different from an ordinary RSS feed is the audio component included in the "enclosure field." Think of it as a feed that talks to you.-http://www.podcasting-tools.com/podcasting-101.htm

    Not yet much of it is music, because they havent figured out the loyalties, but that will come in time.http://www.gseis.ucla.edu/~howard/Papers/pw-public-spaces.htmlhttp://www.gseis.ucla.edu/~howard/Copyright/Elect-publ00/ppframe.htm

    Supposed to be a temporary monopoly, then works become publicly available for all

    The "limited time" duration of copyright guaranteed that works would relatively quickly enter the public domain. This provision was instrumental in ensuring that the law promoted the creation of new works, rather than the extraction of profits from content. The duration of a copyright guarantee has increased over time (see chart A). A 1709 law set copyright for 14 years. Prior to 1976, copyright was granted for 28 years and renewable for another 28 years. The 1976 Copyright Act increased the term to 75 years, and the 1998 Sonny Bono Term Extension Act increased the term still further -- to 95 years for corporations and 70 years after death for individuals.

    After intense lobbying and public relations efforts, members of the content industry have indicated that they would like to see the public domain completely eliminated. In fact, provisions within the 1998 Digital Millenium Copyright Act took works that had fallen into the public domain and put these back under copyright. The 2 companion 1998 copyright acts have taken a wide variety of materials that should be entering the public domain very soon, and placed these back under copyright control for at least another 20 years (which gives the content industry plenty of time to extend copyright for still another 20 years). Songs like Irving Berlin's Blue Skies, Harry Woods' When the Red, Red Robin Comes Bob, Bob Bobbin' Along, and Hammerstein and Kern's Ol' Man River and Showboat should all have entered the public domain next year, yet the new laws will place these all under copyright control for at least another 20 years. Stories by Virginia Wolf, F. Scott Fitzgerald, Ben Hecht, Rudyard Kipling, P. G. Wodehouse, and Zane Grey have also been eliminated from the public domain for at least another 20 years.From BesserFrom BesserOne place to disseminate social commentary are in podcasts and blogs!-from Besser-BesserFrom the article you read for classAnd, I guess you could say that this is one method for file sharingDouble click on a cast to start, then get episode to copy the file to your computer, which can then be transferred to an ipodArticle says they arent charging for podcasts, this seems to include the tv shows tooDont forget to turn up the volume. You can also easily add them to your iPod, or another mp3 player, but it takes a little more effort.-from http://www.podcasting-tools.com/podcasting-101.htmFirst you'll need to use software to record your own audio file. (Audacity is free) http://audacity.sourceforge.net/Youll also need something which allows MP3 exportation(like, Lame MP3 Encoder)3) Once your audio is recorded you'll need to create an RSS feed file. - For step by step directions on making a feed file see this site:http://make-rss-feeds.com/making-an-rss-feed.htm - Heres a great tutorial on RSS here: http://www.mnot.net/rss/tutorial/
