I agree that yes the kids can bypass the boot sequence by knowing some tricks. However, there are other controls that you can put in place that will help the parents know what the heck their kids are up to.
There are many programs out there that parents can buy which will run in the backgroud that will log whatever or whoever is on the computer. This will help one understand what the kids are trying to look at or looking for.
Also, by putting the family computer in the main family room helps you keep an eye on what your kid is up to.
With 3 teenagers in our household, mobile smart phones, wireless router, and other gizmos to keep a multi-tasker generation busy, & away from academic work. It takes family core values to lead by example, instruct how to properly use technology and not allow their time slip away in trivial and non-productive tasks ( facebook updates, tweets, never ending emails... ).
We live by the rules:
* Work before pleasure (homework and chores first, before plugging online).
* Sleep time is a biological necessity that is can not skip (self discipline to at least 6-hour rule).
* Do not post anything online that will embarrass your parents, family or self. Kids need to understand the concept of almost-eternal life- span of electronic media (email,pics and video).
* Finally, preventing a brush with internet sewage is a near impossible task, as mentioned by previous examples. So instead, I urge our youth to pace themselves, explain in your own terms why those are your not core values and help them avoid the filth.
Although I trust our youth, I still do random sweeps to but verify they are in the right path.
This is one topic that needs lot of concern and thoughts. When I show some nursery rhymes to my baby on you tube suddenly there is a video that's not meant for her. There is nothing like parental supervision but how long can we supervise them once they are old enough to google they just wont listen to us. There should be some way to protect kids from surfing on internet other than just id and password. The kind os things there are on internet I feel soon governments whould step in and block.
Our solution was much simpler. All computers were in public places, like the family room, or the dinning room. No controls were used. We explained that all information published to the web was public. Numerous times. When we found out about Facebook, we explained that they have no idea who was running it, nor who had access to their posts etc. Its a difficult concept for a child and many adults.
I'm certain that my children probably explored sites I would not have approved of. However they did it while at home, and hopefully do not need to do so now as young adults.
We had many rules, on not copying music, burning CDs, nor copying games etc. Remember Kaza? Our expectations were pretty high and my kids didn't disapoint me. I figure if they had we would have found out as we would have been infected more often.
Kids learn by making mistakes. Hopefully it doesn't kill them or scar them for life. They will learn that there is information out there that they have no need to see. Better to learn at home with Mom and Dad's help.
David, I agree, as a society we have lost something tangible by moving to this technology driven virtual world...but we also gained...this would be an interesting topic for a debate among all of us who like it or not create means of that change to go forward even more ;-)...Kris
There IS a lot of garbage on the internet and I'm glad in many ways that it was not around when I was growing up. But it is good as well in so many ways. Things like being able to get datasheets for just about any device on demand, or find out something about just about anything via google or wikipedia are great.
It's like most things in society I guess. Everyone has rights, but no one seems to have any responsibilities any more. Society ought to demand a far higher standard of conduct from its members, for the good of all, and apart from a few basic rights, the rest ought to be earned by fulfilling your responsibilities.
When I was a kid (14), life was safe enough that a friend and I could set off on our bicycles to the other end of the country for a week. No mobile phones, no internet, just a call to our folks from a payphone every few days. And that was in Africa... We had such a good time.
I don't have kids, but if I did I'd be sad that there were so many perils in the world, real and virtual, compared to when I was young. I really think we have lost something here with all the freedom that we have gained.
Come on people! The Internet (on which I spend far too much time) is just an enormous garbage dump containing a few items of dubious utility buried in a mass of the boring, inaccurate, lethal, and insane. But it's not in itself physically damaging. Many of the ways in which I and my contemporaries amused ourselves a teenagers (and even younger) in a world without even TV, were potentially life threatening, for ourselves and others, and often illegal. Be very glad that your children are amusing themselves mostly where you have some possibility of control and guidance. If you communicate with them a lot and teach them responsibility at an early age (which means allowing them to make mistakes and learn the right lessons from them without fear of excessive punishment) they will manage their own lives better than you can hope to.
