"You've seen it countless times on bags, coffee shop walls and on coffee company websites: The image of a farmer picking ripe coffee cherries, designed to connect consumers to the origin of their coffee and perhaps even provide a face for farmers themselves", RoastMagazine. My question: Do you think a coffee grower could sue any of these companies?

About MathTV Our History The current version of MathTV.com was started in 2008. That summer, Mr. McKeague hired six of his students to help him proofread and error check a college algebra book he was working on. Because of the extremely positive attitude of his students toward improving the book they were proofreading, Mr. McKeague decided to see how the students would do in the studio. With a little coaching they actually did very well. In 2009, we started adding online versions of three of Mr. McKeague's textbooks to the website, and experimenting with building an online homework system. In 2010 we published the first print versions of those textbooks with our new publishing company XYZ Textbooks, and we officially launched our online homework and gradebook software with XYZ Homework. As of now over 80 schools use our books.

It's great idea to start MathTV.com. I will show to my kids too

Hi, there I think that we must talk about this issue, is very important to know more about it. Russian hackers have pulled off what is possibly the largest cyber security breach in history, stealing 1.2 billion usernames and passwords and more than 500 million email addresses, security experts say. More than 420,000 websites, including large, well-known sites as well as smaller companies, were targeted by a cybercrime ring dubbed Cybervor.

Relating to the digital copyrights issue, here's a recent article regarding Satellite radio…in this day and age where new and old music is being played, it's become more confusing as to what rights music services (or other arts) have. They might be playing music that they may or may not have the right too (and yet bands have no idea). Unfortunately copyright laws seem to have a long way to go before they become untangled. In the battle between today's digital-music services and yesterday's oldies artists, score one for the geezers. The founders of the '60s rock band the Turtles won a summary judgment on Monday against Sirius XM Radio Inc., in a lawsuit alleging that the satellite-radio company violated California copyright law by playing the band's songs without permission.

Interesting lecture on privacy and digital identity. Do you want everybody in the plane to have your facebook account? Our personal information is the product the big companies are selling to their advertisers, so they are not so interested in helping us protect that information.

But is there a way to 100% protect our privacy because digital identity in the first place they aim to make us visible without us realizing that we are visible. So when we become visible how then can that be privacy. The story of emperors new clothes (http://en.wikipedia.org/wiki/The_Emperor%27s_New_Clothes) clearly relates to the whole issue of privacy and digital identity.

Very interesting aspect of how to protect our personal identify by using selective attributes like age, gender when appropriate and needed by various websites.

From the invention of the printing press to the telephone, the radio, and the Internet, the ways people collaborate change frequently, and the effects of those changes often reverberate through generations.

LONDON, Sept. 16, 2014 /CNW/ - EF Education First announced that the EF Standard English Test (EFSET), the world's first free standardized English test, will be released on September 30, 2014. The EFSET will also be valuable to schools, companies, and governments, where large-scale testing was previously cost prohibitive. In the coming years, EF will work with institutions that want to adopt the EFSET as a formal English certification test, thereby helping millions of students and employees. This looks interesting, I wonder what kind of adoption rate we will see. It could really be a disruptor.

With the ongoing patent wars between hi-tech companies, the emphasis on IP and patents has never been greater, and businesses are realizing the value of strong IP lawyers.

Reuters / Eric Thayer Internet giant Twitter is suing the Department of Justice in hopes that the United States government will let the web company publish more details about requests made for user data. The complaint, filed in federal court on Tuesday this week, asks the Justice Dept.

An interesting read. Freedom of speech is allowed as long it does not relate to the US government. One important thing to understand here is that the flow of information can never be stopped or banned (at least only temporarily.) There is no such thing as good or bad information - it all depends on who interprets the information and what point of views these people have.

Regarding Open Source/Access, good article on whether students consider Wikipedia a good source for information. Since its introduction in 2001, Wikipedia has grown to host more than 19 million articles with 82,000 contributors in more than 270 languages. Wikipedia has 400 million unique viewers each month as of March 2011, According to ComScore, an Internet marketing research company that provides marketing data to large Internet businesses.

Want to let people share and use your photographs, but not allow companies to sell them? Looking for access to course materials from the world's top universities? Want to encourage readers to re-publish your blog posts, as long as they give you credit? Looking for songs that you can use and remix, royalty-free?

A federal database publicly disclosing companies' payments to doctors went live this week, drawing a splash of attention to the $3.5 billion given to physicians over 5 months last year. Although one purpose of the site is to shine light on potential conflicts of interest in research, the site may fall short of that goal.

"The edupunks are on the march. From VC-funded startups to the ivied walls of Harvard, new experiments and business models are springing up from entrepreneurs, professors, and students alike. Want a class that's structured like a role-playing game? An accredited bachelor's degree for a few thousand dollars? A free, peer-to-peer Wiki university? These all exist today, the overture to a complete educational remix."

Emotional expression and linguistic style in online collaboration differ substantially depending on the contributors' gender and status, and on the communication network. This should be taken into account when analyzing collaborative success, and may prove insightful to communities facing gender gap and stagnation in contributor acquisition and participation levels.

lubajong and taylor_cole thank you for your comments. From my part I will add a critical evaluation of this resource as well. The talk pages of Wikipedia provide a rich source for researchers to study communication patterns. On Wikipedia talk pages they have found signals for status differences between groups of participants, notably between admins and ordinary contributors. Those findings support in general the theories of the researchers about status differences and communication style differences between managers and employees in firms. They have also found differences in communication style bases on gender, which also support their general theories about gender (which is a social construct). What I - as a Wikipedian insider - finds missing in the article is the selection bias. Wikipedia admins aren't appointed by Jimmy Wales or some other body. Admins are community selected. The exact process differs per language version. On the English Wikipedia admin selection is by a community consensus process. Future admins are selected who show the preferred communication style of admins by other contributors including existing admins. For me, the patterns in communication style do not explain the gender gap on Wikipedia. There is a gender gap in many language versions of Wikipedia, but not in all. The Armenian language version of Wikipedia is a notable exception, showing a gender balance in the conbtributor base. An explanation of that exemption requires further research. What taylor_cole notes about neutrality and bias is a valid point. People volunteer to write for Wikipedia, and volunteer in topic choice. My guess is that in general people will opt to write about something they like, care about, know about. A lack of diversity in contributors will naturally reflect in lack of diversity of topics. For example nerdy males will write about things male nerds like. In general females tend to be interested in other topics than nerdy males. A lack of topics covered in Wikipe

Levels of participation influences emotional expression and phrasing? has the function of sex and status of the taxpayer. 4 strands to study and find a result! Interesting!

There has been a recent surge of interest in open source software development, which involves developers at many different locations and organizations sharing code to develop and refine programs. To an economist, the behavior of individual programmers and commercial companies engaged in open source projects is initially startling.

Blogs are used as educational resources and we can have our blog nowadays for free.

Very useful, thank you. I made two free websites not long ago and then two days later, the company sent me messages that to keep them I had to pay for the service. Then it is not free, is It?

Sometimes 'free' meens that you should pay money latter of for best services.

Learning and teaching will be severely damaged, many publishing companies will close and thousands of jobs will be lost if the government implements its proposal to remove any choice in which textbooks schools use. Basic Education Minister Angie Motshekga published the policy proposal in the September 4 Government Gazette and invited public comment on it.
