Ok, now why would we want to have our speed limits reduced from 120 to 100? Honestly, do you really think that people who completely destroy and obliterate themselves (and their cars) are driving at 120 or below? What will reducing the limit really do? Well, once again, the honest law abiding citizen has to pay the price. There will still be carnage on the roads as long as Minibus Taxis, yes, Minibus taxis are on the road ignoring speed limits and rules for the road.
A Speed limit is only applicable if the cop is visible or if they know he is hiding on the bridge or bush. Whats a Board saying 100 going to do? Well, in my opinion, nothing really

The programming blues
Many students including myself sometimes find programming to be an absolute nightmare but we all need to persevere and learn it to be the best that we can be in our fields (if we are in the field of software development).
The hardest thing that I have found is that students sometimes find it difficult to understand the way a computer thinks. As humans, we assume alot of things as they "make sense".
If i had to ask you what is 1 + 1, you don't even need to think about it to say the answer is 2.
Now, the computer, although can calculate and display the answer faster than us, they ACTUALLY calculate this answer everytime it's needed as they don't have the skills that we have.
Example:
If i asked you what 12*24 is, you would need to pull out your calculator to get the answer.
the answer is 288 by the way :)
Chances are that the computer beat you to the answer (you did use a calculator which is a form of processing unit, which is a type of computer)
You now remember this answer, if i asked you again, you dont even need to pull out the calculator because you remember it. The computer does not have this skill to remember, if you asked the computer again, it will recalculate this formula.
