ruby on rails - Open source alternative to Google Earth -

-

I need to create a website that needs to do the following:

  1. Geographic
  2. When a road is selected, show a set of points of interest on that road
  4. Show a set of selected roads on the map / Ol>

    The obstacles are:

    1. Ruby on the rail
    2. Everything in the stack should be open source

      I have a What is the need to see it necessary Work tasks?

      At a glance or OpenstreetMap will only allow you to load maps in a visualizer (this is a collaborative geodatabank Seems like), and at least Openstreetmap's younger brother / visualizer / tool for the OpenLeary version. I've heard Mapfish is a plugin for rail integration, but I do not know what it is. Best wishes to learn the API of your choice!

php - Creating canonical URLs with custom route-classes -

-
I am trying to implement the canonical url and to combine with custom route classes. URL-SACAME is something like this: / category-x / article / 123 / category-y / article / 123 I am creating a custom route - the expansion of the class Zend_Controller_Router_Route_Regex and checks that the article is 123 and the correct category-name is included in the URL. If the article is in 123 square-X and the user is reaching square-y, then I want to redirect to the correct URL. But there is no clear possibility to do this directly to the roads. What is the best practice approach here? I often do this in my action controller like something ... // Get / Category-Y / Article / 123 $ $ article- & gt; URL is generated, and it contains / category-x / article / 123 if (this-> --request-> getRequestUri ()! = $ Article-> URL) {return $ this- & gt; ; _helper-> Redirector-> GoToUrl ($ paragraph-> url); } In this example, $ article-> The url will need ...

Occasionally, in 1 and 3 out of 1 to 3 times, I get the...

In anticipation of a live scenario, I am creating my entire site, which has a 500 MHz processor with 256 MB A very large 100 MHz RAM I have loaded my database with 200k + rows of garbage data, trying to test my queries. I have seen - obviously because of this, a large display hit all my FAQ using the index, although some 15+ to join (using all indexes) using MySQL To enable 16MB cache, which brings down the query times to nothing but what results? With a dynamic website, I can not see how the cache can help completely when I allow unique queries such as a search feature. I am also using the eaccelerator for PHP. When I use the COUNT (*) total with multiple code JOIN and WHERE , then 10 + There are other queries. Other queries that only get the same line or two do at the same level when I had only a few lines I also noticed that almost 99% of the CPU in CPU CPU stress during a query Comes. Basically I do not know whether the software is on the fault or too much of the h...
