Slammer (also known as Sapphire, Helkern or SQLExp) was a worm that appeared in 2003 January and was the fastest-spreading worm of its time. The worm was an extremely simple piece of code and its payload was an unintended byproduct of its spreading ability.
Spin Direction. The biggest thing I see people struggling with when they use a string trimmer is spin direction. Just as a circular saw needs to eject sawdust as it works, a trimmer needs to eject debris from its cut path. If your trimmer spins counter clockwise, it ejects material from the left side of the tool and cuts best with the right side. So if you're moving along a walk, curb, or low fence, keep the right side of your body closer to the work, which will position the head of the tool so it can cut and eject to the left.
