@jlrdw Thanks.

I too am developing at a very small scale, probably not even in distant comparison of such huge projects, but just got intrigued about what would be the factors driving mix of technologies.

I guess probably, such huge projects would be making their decision from collective wisdom of large number of tech experts they have at their disposal.

I have a dream of building an education portal someday, with lots of features for self paced learning on various topics - primarily school and college education with focus on progress made, reminder alerts and many such things which would make learning fun as well as self-encouraging. The main agenda is that I would like to ultimately make it free for all - all across the globe. Special focus to provide content in various languages especially for geographies with population consisting sizeable proportions of underprivileged or war/terrorism devastated fellow citizens of our world. Cause I believe that if kids and very young citizens have easy and free means for studying, they can develop themselves into good human beings and bring about a change in world order focused towards peace and development.

This kind of a project would be a significant effort much beyond the level at which I am working currently, but I guess I will have to start some where and then God willing I may be able to do at least something near to what I dream of.

Sorry for the digress, but every time I hear about how something was used in a huge project, I try to get some details thinking I might require something similar for the education portal. Thanks for your good wishes, wish you good luck too.

@neeravp funny you mention that sort of site, State of Texas has online training courses that is kinda slide show format, yet in middle of course they have popup quizzes. I cannot remember the software used, but I think it was something from adobe. Anyway somehow it was made fun and interactive. One had a thing when you answered a question correctly, a reward was added to your score pile, that sort of thing. Hard to describe, but I liked the way it was done.

@jlrdw Probably SCORM

i have to say this discussion about LTS and the update from the owner is a little bit disappointing.

i have a production project running 4.0 and was planing to update to php7 and so to newest LTS versions.

all those breaking changes between minor versions dont make sense for me. i dont know why are they calling it 5.2 to 5.3 that should be 5 to 6.

and then we would be now at the version 10 or so, and maybe they would take a hint and not change so many things without a real reason, or think about those things in the first place.

somebody could say, nobody is forcing you to update and that's true, but if most of the packages also target the latest version, and patch only the latest versions i i kinda have to care.

take a look at ubuntu 12.04 LTS that alot of people are still running on some of those systems.
