old timers will tell you to put it in the positive + {hot} line but they have found out that it is possible to get a feed back loop and you should also have a fuse in the negative - {ground} line.

The fuse should go on the positive wire. If the fuse is put on the negative wire then it may not blow if there is a short circuit and there is a risk of electrocution.

Nearest to the power source, i.e, the plug or transformer,
as the aim is to protect the circuit from damaging the fuse is place near the power source so when the current or voltage is high it fuses

It goes on the power side (hot in A.C.. "+" in most DC) because you want it to interrupt the available power. In an AC circuit if it is not on the power side you will still have 120V or 220V active to the device and you could get shocked.
In Europe they are requiring both sides to be fused at least on some products of the companies I have worked for.

As close to the source of the power as possible so as to protect as much of the wiring and following circuitry as possible. In an AC line circuit, on the LINE (as opposed to the neutral or the ground) side.

The function of a fuse is to interrupt overcurrents,
so in general, a fuse should be placed in each ungrounded conductor as close to the source as practicable.
(I can't think of any exceptions offhand, but I'm
sure somebody will.)
