Business opportunities around MOOC

MOOC (massive open online courses) become popular more and more. Lots of people are involved in a discussion about MOOC. E-Learning portals publish news and press releases related to MOOC every day. Millions of students learn courses and leave their feedback. One of most popular discussions related to MOOCs is about if is this possible MOOCs replace traditional higher education.

Many experts think it is too early to say about real revolution in higher education as MOOC can not ensure getting of all skills a student can get in a college. A practice aspect of education process is missed. And also a college atmosphere is very important thing and can not be compensated with something when a student learns with MOOCs.

MOOC providers don't have alternative for things outlined above. But someone other can provide alternatives to that things. And this is good business opportunity to offer services around MOOCs aimed to replace traditional college things missed in MOOCs.

Future of higher education

Will higher education system differ in future?

To get the answer on this question we need to understand if is everything all right in higher education. If modern higher education system is correct and everyone (or almost everyone) is happy with it then no need in changes. But if there are problems then we can expect changes.

Does modern higher education system have problems? If we care only about USA and West Europe (and other developed countries) then we could say “Higher Education will slowly transform under the influence of technology. All core principles will stay unchanged”. The reason is obvious. Developed countries built good higher education system. It filters gifted and talented children and allow them to get higher education for free or for low price. Such system seems even and, in general, satisfies the requirements of society. Of course, there are problems. On my opinion, on of biggest problems is not reasonable value for money . Nevertheless, imbalance is not sufficiently serious to accelerate changes.

What about developing countries? Population of such countries is bigger then in developed countries and there is no fair higher education system. Many gifted and talented children have no chance to get higher education. The have choice – pay big price to get good higher education or pay less money to get low quality education (formal higher education without real background) or get nothing and lose chance to go up with social ladder. What if they get some alternative that are cheaper then traditional higher education? They definitely need the alternative because something is better then nothing.

Joomla 1.7 site hacked. What to do?

Recently my Joomla 1.7 site was hacked. I knew nothing about this. The site worked fine. But when i did some test search with Google and found that the site is found with keywords that are not used in my site. When i looked at Google cache i was impressed that there are different pages. Contents of my pages was replaced with advertising links and texts.

This was some sort of cloaking. And this meant my Joomla site is infected with something bad.

I already sow similar problem for my another Joomla 1.5 site year ago. So this time i know what to do.
