• Genetic/Evolutionary algorithms and local minima/maxima problem

  - by el.gringogrande

  I have run across several posts and articles that suggests using things like simulated annealing to avoid the local minima/maxima problem. I don't understand why this would be necessary if you started out with a sufficiently large random population. Is it just another check to insure that the initial population was, in fact, sufficiently large and random? Or are those techniques just an alternative to producing a "good" initial population?

• Get number of concurrent users online - ASP.NET

  - by Srikanth

  I would like to know the number of users logged into my ASP.NET 2.0 application. Points to be considered: 1) Simplest way would be to use Application or Cache object to have the counts on Session start or end. However this would fail if there is a worker process recycle. Wouldn't it? 2) Should't make a difference whether the session is inproc/state server managed/ or SQL server managed. 3) Should preferably be seamless to a web-farm architecture.

• Memory release from local variable in javascript

  - by Bob

  Quick question. I have a js function which gets called on the page every few seconds. It's an ajax update thing. Being a function, I declare local variables. I don't want to use closures or global variables for various reasons. I'd never considered this, but do I need to release/clear the variables at the end of the function to release memory or will js do this for me automatically ? Thanks

• leiningen - how to add dependencies for local jars?

  - by signalseeker

  Hi, I want to use leiningen to build and develop my clojure project. Is there a way to modify project.clj to tell it to pick some jars from local directories? I have some proprietary jars that cannot be uploaded to public repos. Also, can leiningen be used to maintain a "lib" directory for clojure projects? If a bunch of my clojure projects share the same jars, I don't want to maintain a separate copy for each of them. Thanks

• How to test an openshift application on local host

  - by panipsilos

  I recently start playing with Openshift and I am wondering if there is a way to deploy ( test) your application on local host before you upload it on openshift. Thing is that every time I make change on the code, it takes some time to push it to openshift and check if it works. Google app engine SDK ( for Eclipse), for example, includes a web server application (app engine simulator) that allows you to test your app locally before you deploy on google. thnx Fotis
