• Real world examples of Rx

  - by theburningmonk

  I've been playing around with the Reactive Extension for a little while now, but mostly limited to handling/composing user driven events within a WPF frontend. It's such a powerful, new way of doing async programming, and I'm curious as to what other people are doing with it, and where do you think it might be able to improve the way we're currently doing things?

• Java weird generic return type

  - by drozzy

  Browsing through Guava libraries I saw this weird signature on a readLines method from Files class: public static <T> T readLines(File file, Charset charset, LineProcessor<T> callback) I know a little bit about generics in java, but this baffled me. What does the double T mean here? And why is the first one in angled brackets?

• Handling right-click within a MenuItem

  - by tylerl

  Is it possible to check for a right-click on a menu item in .NET? It appears that the framework doesn't expose it as an Event, but I've seen other applications (like Chrome and Firefox) which allow you to bring up a right-click context menu for a menu item. Presumably with a little event-loop magic you can do the same thing in .NET, right?

• Why is C++ backward compatible with C ? Why isn't there some "pure" C++ language ?

  - by gokoon

  C and C++ are different languages, blababla we know that. But if those language are different, why is it still possible to use function like malloc or free ? I'm sure there are all sort of dusty things C++ has because of C, but since C++ is another language, why not remove those things to make it a little less bloat and more clean and clear ? Is it because it allows programmers to work without the OO model or because some compilers doesn't support high-level abstract features of C++ ?

• Cross platform GUI Programming with D

  - by Adam Hawes

  I want to start programming with D. I have a simple application in mind that needs a GUI but I want to make sure it's portable to Linux/Windows/Mac equally well and with minimal (no) change for each platform. wxD is looking like the contender of choice because I know the wx toolkit already. I see fltk4d as a contender and a (unfinished) wrapper around Qt. Are there any other truly cross platform GUI toolkits for D that will go where I want with little effort and what would the the toolkit of choice for people here?

• How to build a tree from a list of items and their children recursively in php?

  - by k1lljoy

  I have a list of items stored in the DB, simplified schema is like this: id, parent, name I need to generate a tree structure (in a form of a multi-dimensional array) that can be infinite levels deep. Top level items would have parent = 0. Next level down would have parent equal to the the id of the parent item, fairly straight forward. What would be the best way to do this, while consuming as little resources as possible?

• Strange behaviour of keywords within macros in Clojure

  - by mikera

  I'm a little confused by how keyword accesses seem to behave in Clojure when they are evaluated at macro expansion time. The following works as I expect: (def m {:a 1}) (:a m) => 1 However the same keyword access doesn't seem to work within a macro: (def m {:a 1}) (defmacro get-a [x] (:a x)) (get-a m) => nil Any idea what is going on here?

• What is the recommended way to do DRY web development (SASS+HAML, LessCSS, etc) in non-Ruby projects

  - by T.R.

  I've been looking to make things a little more DRY, both on my personal projects (django) and at work (JSP/struts,PHP). SASS+HAML seem to be quite popular, but, do those outside of the Rails community generally use these as well, or do they opt for other similar solutions? Which do you use, and what was the reasoning behind the choice?

• Covariance and contravariance real world example

  - by Sir Psycho

  I'm having a little trouble understaing how I would use covariance and contravariance in the real world. So far, the only example's I've seen have been the same old array example. object[] objectArray = new string[] { "string 1", "string 2" }; It would be nice to see an example that would allow me to use it during my development if I could see it being used elsewhere. Can anyone point me to some useful resources?

• Agile Whiteboard Software

  - by PaddyC

  Can anyone recommend decent software that could replace a physical whiteboard, as used in Agile development? I've had a look at http://www.brightgreenprojects.com/ but ideally we'd like something we could host ourselves. We use Jira for issue tracking, and are looking at integrating GreenHopper for project management at the moment. The general feeling among users so far seems to be that GreenHopper is a little clunky. Is there a more straight-forward agile whiteboard software tool out there?

• ant (1.8.0/1.8.1) zip empty directories

  - by andersonbd1

  Hi, I noticed that neither the zip or jar targets are including empty directories. I googled a little and found this was a regression issue way back with 1.6 (.2 I think), but it was claimed to have been fixed. I was using 1.8.0 so I upgraded to 1.8.1, but am having the same issue. Anyone know of any workarounds besides adding dummy files to those directories? Thanks, Ben Anderson

• Why isn't the SQLiteOpenHelper called just SQLiteHelper?

  - by Emanuil

  The documentation describes the class as a helper object to create, open, and/or manage a database. Having that in mind wouldn't you say that the name is a little misleading?

• Why JEE is widely used in complicated projects?

  - by cane

  Hi. Yesterday me and my friend we've had nice conversation about IT and he asked me WHY JEE is so widely used when it comes to build complicated IT systems? From my point of view advantages are easily visible, but he is IT manager with a lot of Micro$oft experience (and little Java exp.), so I would like to hear your voice. And I'll give him a link of course. I don't want new .NET - JAVA war - just - why JEE :) Thanks, orsonek

• 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!
