  1. Turn Off Javascript by eldavojohn · · Score: 4, Informative

    Before I dive in, I have to say that I don't think you adequately explained the requirements here. In one part you seem concerned about configuration, in another you seem concerned about security & finally it seems to come down to being too sophisticated for the user.

    I'm not sure which one you value the most. But, assuming we need all three, I would suggest something like the OLPC as an everything. Yes, it's geared for children but I guess you're kind of dealing with ... well, in some cases degenerated minds. I don't say that to be mean but ironically my four year old cousin and my 80 year old grandfather have some of the same needs when it comes to high tech gadgets.

    One step up from that would be to use a premade Live CD of Ubuntu or Dragonfly or some other easy live Linux OS. You show them how to reboot with it and then they can surf like that. The downside is they can't save anything to disk but the upside is they can't save anything to disk :). Granted, this may violate your sophistication requirement (and destroy caching), it has the huge benefit of going "Oooops, time to simply reboot."

    You know, the last college I attended had labs where you had administrative privileges but they reverted to a system restore point nightly. As a result, there would be screwed up machines but only for a day or week at most.

    But, if we assume you don't want to reboot with a live CD of the OLPC or Ubuntu, you could instead simply turn off cookies & turn off javascript. Why? Because javascript is the devil. I think it has some of the most flawed type casting (if I can call it that) out there today. It's not a "type safe" language. And the proliferation of JSON objects in Javascript is frightening. But once you eliminate cookies & javascript, you also eliminate a lot of functionality.

    I would suggest giving them the flash plugin (pending system requirements) as it's not so bad anymore. That and they'll probably want to watch YouTube videos of their offspring. I think that is a fair trade being as the latest Flash plugin is fairly secure.

    So, I would finally recommend you give them plain jane mozilla firefox with no javascript or cookies & the flash plugin. It probably wouldn't hurt to jack the security meter up to the top and just tell them that sites they can't access are bad sites anyways.

    Once again, I could use more requirements before giving you a final assessment but the above two options sound like they would come pretty close to satisfying your (and their) needs. These were made under the assumptions that these people suffer from learning disabilities in their old age and, as a result, you cannot host training sessions whereby you show them safe & secure internet usage.

    In the end, I predict that some of the users are going to find a way to make it hard for you and them. I suggest starting with the lightest steps and only progressing forward as necessary.
