• Is there a .Net library similar to GNU readline?

  - by paul.moore.name

  I'm considering writing a console application in C# and I want to incorporate history, completion and command line editing features something like GNU readline (but not necessarily as extensive as that!) Is there an existing library for .net which provides this type of functionality? I guess one option would be to use interop services to call GNU readline. But is there a native option?

• Dealing with &rest-parameters in common lisp

  - by Patrick

  I want define a functions that accepts &rest - parameters and delegates them to another function. (html "blah" "foo" baz) = "blahfoobaz" I did not find a better way than this one: (defun html (&rest values) (concatenate 'string "" (reduce #'(lambda(a b) (concatenate 'string a b)) values :initial-value "") "")) But this looks somewhat glumbsy to me, since line 4 does no more than concatenating the &rest parameter "values". I tried (concatenate 'string "" (values-list values) "") but this does not seem to work (SBCL). Could someone give me an advice? Kind regards

• How do I perform this XPath query with Linq?

  - by John Hansen

  In the following code I am using XPath to find all of the matching nodes using XPath, and appending the values to a StringBuilder. StringBuilder sb = new StringBuilder(); foreach (XmlNode node in this.Data.SelectNodes("ID/item[@id=200]/DAT[1]/line[position()>1]/data[1]/text()")) { sb.Append(node.Value); } return sb.ToString(); How do I do the same thing, except using Linq to XML instead? Assume that in the new version, this.Data is an XElement object.

  - by Trevor Burnham

  I was just digging through some JavaScript code (Raphaël.js) and came across the following line (translated slightly): Math.min.apply(0, x) where x is an array. Why on earth would you do this? The behavior seems to be "take the min from the array x."

• Good C++ Debugging/IDE Environment for Linux?

  - by Brandon Pelfrey

  I have a friend who is trying to make the switch to Linux, but is hung up on the apparent lack of debugging/IDE environments for C++, especially as they relate to template programming. He has been using visual studio for years and is maybe a little spoiled by their awesome IDE. Does anyone have any good suggestions for an environment where he can, under Linux, develop and debug with all of the usual things (Breakpoints, line highlighting for compilation errors, step in/over/out/etc, etc) that he's accustomed to? Thanks!

• Connecting GPS coordinates taken from a database in Android using Overlay

  - by LordSnoutimus

  I am currently building an application that allows users to track where their phone has been on a Google Map. At the moment, when the onLocationChanged() method is called, the application stores the current GPS longitude and latitude in a database and calls the animateTo() method to the current position. Using SDK 1.5, how would I go about connecting these points with a coloured line drawn on the MapView using an Overlay?.

• ajax cross-domain requests

  - by yoda

  Hi, Since Ajax requests are limited for security reasons, there's not much to it, just follow the rules eh .. but I've crossed with this : https://developer.mozilla.org/en/Same_origin_policy_for_JavaScript It's written that you can "bypass" those rules, in case you're working with subdomains of the same domain, with the following javascript line : document.domain = "company.com"; I haven't tried it yet, since I don't know if this only works (perfectly works) with any other browser, or at least the major ones. Is it possible? Thanks.
