Since material related to J is mostly concentrated on jsoftware.com, I've sometimes found it more fruitful to use the J wiki's built-in search engine rather than Google. For example, try typing "Collatz" into the search box at the top-right corner on any J wiki page, and hit "text" (not "titles", that's almost always way too restrictive, though in this particular case it would work ok).
However, in this case, I actually typed [Collatz site:jsoftware.com] into Google (where the []s represent Google's search box, and shouldn't be taken literally as part of the search terms). That usually works well too (sometimes better than the Wiki's built-in search), but in this case it only worked because I knew what I was looking for, and I knew it actually existed on the site. Because, when I tried it, while the Essay in question was actually the first result returned, what I actually saw was: Source - Jsoftware jsoftware.com/jwiki/Essays/Collatz%20ConjectureJ A description for this result is not available because of this site's robots.txt learn more Where "Source - Jsoftware" would usually be the title of the linked page, and the only way I knew this result was actually the essay I sought was the URL below that, which included the words "Collatz Conjecture". Someone should probably look into this [1]: SERPs (and, by implication) SEO is the internet's analog to one's storefront. Bloomingdales probably wouldn't be doing so well if they blacked out all their window displays and wrote "Macy's" on them. -Dan [1] Starting with http://www.jsoftware.com/robots.txt as Google's complaint suggests) ----- Original Message --------------- Subject: Re: [Jprogramming] Memoizing (Project Euler problem 14) From: mvillarino <[email protected]> Date: Mon, 4 Aug 2014 18:30:58 +0200 To: [email protected] 2014-08-04 14:12 GMT+02:00 Dan Bron <[email protected]>: > If you're OK with spoilers, have you seen Roger's Collatz Conjecture essay > on the Wiki? > > http://jsoftware.com/jwiki/Essays/Collatz%20Conjecture > ?
