It is nice to have a button in empty story river or on the sidebar, on lick shows a random tiddler. I have such a button in TW-Scripts and Mehregan. The button uses the computer time as seed and its output is deterministic, so it does not generate a real random number, but is very handy for our daily use and has no performance impact.

This solution is pure WikiText, no JavaScript.

```
\define randomTiddler(filter, label)
<$let seed=<<now XXX>>
minNum = 1
maxNum = {{{ [subfilter<__filter__>count[]] }}}
randNum = {{{ [<maxNum>subtract<minNum>multiply<seed>divide[999]add<minNum>round[]] }}}
>
<$link to={{{ [subfilter<__filter__>nth<randNum>] :else[subfilter<__filter__>first[]] }}}>$label$</$link>
</$let>
\end
```

**Logic**

If we linearly map `[0, 999]`

into `[alpha:1, beta:n]`

where `alpha`

is the first tiddler and `beta`

is the number of tiddlers to be used for random display! from mathematics we have

`x`

in `[0, 999]`

(this will be generated by `now`

macro)

`y`

in `[alpha, beta]`

(this is the numbers we like)

then` y= (beta - alpha) / 999 * x + alpha`
