Another issue has cropped up this week about personal data, privacy and just how vulnerable people are when they go on social media.  This time it involves an “experiment” that Facebook conducted on its users without telling them.

In fact, about 700,000 users were involved in the experiment over a period of two years, and British, French, and now Canadian authorities are looking into the case

Facebook says it was to gather information that it needs to keep users interested, but has since apologized.

Lynn speaks with independent technology analyst Carmy Levy.

A new study shows once again how seemingly non-connected things in nature are interconnected.

the study looked at the health of fish in boreal lakes and found that the more forested the area, the healthier and greater the population of fish in the lakes.

The scientists determined that when a lake was surrounded by thick forestation, most of the biomass of the fish could be traced through carbon-13 tracing, back to its origins in the forests. Less forests resulted in less biomass in the fish and less of that mass came from forest origins.

In other words the healthier the forests, the bigger and more numerous the fish in the lakes will be.

Marc spoke with Professor Michael Arts of Ryerson University who said this points out another reason fore maintaining forests if we hope to have fish as a commercially viable source of protein and omega fatty acids.

Carmel looks at an arts story this week, World famous Scottish-born painter, Peter Doig spent most of his formative years in Canada and that is reflected in several of his paintings.  In fact, recently a painting inspired by a Toronto Ontario scene recently sold at auction in London for over 15 million dollars.

It’s called “Country Rock (wing mirror)” but most people know it as Rainbow tunnel.  It features a scene from a very busy major highway in Toronto called the Don  Valley Parkway. While travelling along the highway one passes a nearby pedestrian tunnel where the entrance had been painted in a rainbow, and that is the image Doig recreated.

Carmel spoke to Stephane Aquin, curator of a recent Doig show in Montreal. They spoke about this particular painting, and the sucessful Doig show.

Radio Canada International does not endorse any of the views posted. Your comments will be pre-moderated and published if they meet netiquette guidelines.

Netiquette »

When you express your personal opinion in an online forum, you must be as courteous as if you were speaking with someone face-to-face. Insults and personal attacks will not be tolerated. To disagree with an opinion, an idea or an event is one thing, but to show disrespect for other people is quite another. Great minds don’t always think alike—and that’s precisely what makes online dialogue so interesting and valuable.

Netiquette is the set of rules of conduct governing how you should behave when communicating via the Internet. Before you post a message to a blog or forum, it’s important to read and understand these rules. Otherwise, you may be banned from posting.

  1. RCInet.ca’s online forums are not anonymous. Users must register, and give their full name and place of residence, which are displayed alongside each of their comments. RCInet.ca reserves the right not to publish comments if there is any doubt as to the identity of their author.
  2. Assuming the identity of another person with intent to mislead or cause harm is a serious infraction that may result in the offender being banned.
  3. RCInet.ca’s online forums are open to everyone, without regard to age, ethnic origin, religion, gender or sexual orientation.
  4. Comments that are defamatory, hateful, racist, xenophobic, sexist, or that disparage an ethnic origin, religious affiliation or age group will not be published.
  5. In online speak, writing in ALL CAPS is considered yelling, and may be interpreted as aggressive behaviour, which is unpleasant for the people reading. Any message containing one or more words in all caps (except for initialisms and acronyms) will be rejected, as will any message containing one or more words in bold, italic or underlined characters.
  6. Use of vulgar, obscene or objectionable language is prohibited. Forums are public places and your comments could offend some users. People who use inappropriate language will be banned.
  7. Mutual respect is essential among users. Insulting, threatening or harassing another user is prohibited. You can express your disagreement with an idea without attacking anyone.
  8. Exchanging arguments and opposing views is a key component of healthy debate, but it should not turn into a dialogue or private discussion between two users who address each other without regard for the other participants. Messages of this type will not be posted.
  9. Radio Canada International publishes contents in five languages. The language used in the forums has to be the same as the contents we publish. The usage of other languages, with the exception of some words, is forbidden. Messages that are off-topic will not be published.
  10. Making repetitive posts disrupts the flow of discussions and will not be tolerated.
  11. Adding images or any other type of file to comments is forbidden. Including hyperlinks to other websites is allowed, as long as they comply with netiquette. Radio Canada International  is in no way responsible for the content of such sites, however.
  12. Copying and pasting text written by someone else, even if you credit the author, is unacceptable if that text makes up the majority of your comment.
  13. Posting any type of advertising or call to action, in any form, to Radio Canada International  forums is prohibited.
