This is fucking disgusting . Animals should never be forced to fight like this for our entertainment . Whoever is running this cat fighting ring needs to be caught and arrested . <| sep |> Well HarleySport 1200 , learning is never a waste of time and I would encourage you to take advantage of all of the FREE learning that is available via edX . Depending on your employer would answer the question on whether or not the certificate is valid . Many companies in my experience are looking for individuals that can perform the task hired for and not so much the certifications . If you have certifications , however , that show you have the knowledge and skills to perform those task , then your certification verified via edX would be beneficial . I ' ve ventured down this road already and have found that many online certification don ' t mean much to employers . This is largely in part due to employers not finding online learning websites as a viable institution for learning . I firmly believe it all depends on you and what you feel is necessary . I ' m currently taking nanodegree courses with Udacity . com and courses on edX . org to help my overall growth potential . I like what Udacity offers and enjoy the free courses on edX . org . I will be paying for verified certifications for some of the course on edX , particularly , the CS 50 course which will help me with future schooling . Best of luck on whatever you do , but remember that practice makes better , not perfect .
