  • C++ for Ruby scripters

    - by Aaron Cohen
    I am a fairly capable Ruby scripter/programmer, but have been feeling pressure to branch out into C++. I haven't been able to find any sites along the lines of "C++ for Ruby Programmers". This site exists for Python (which is quite similar, I know). Does anyone know of a guide that can help me translate my Ruby 'thoughts' into C++?

  • Converting DTOs to View Models

    - by illvm
    Does anyone know of a good (read: quick to code) method for converting DTOs to View Models or mapping DTO members to View Model members? Lately I've been finding myself writing many conversion and helper methods but this is a very arduous and tedious task. Moreover, it will often needs to be done twice (DTO - View Model, View Model - DTO). Is there a methodology, technique, or technology which would allow me to do this more quickly and efficiently?

  • Clone List Elements in Java

    - by Amir Rachum
    Hi all, I have a variable of type List<RelationHeader>. Now I want to copy all the elements in this list to a new list, but I want to actually copy all the members by value (clone them). Is there a quick command to do this, or do I need to iterate over the list and copy them one at a time?

  • Is there a "fancy" Ruby way to check whether a local variable is both defined and evaluates to true without using ands and ors?

    - by Steven Xu
    This is quite a quick question. I currently use do_this if (testvar ||= false) Which works just fine. But this approach unnerves me because while fast, it does not short-circuit like defined?(testvar) && testvar does, and it instantiates and assigns a value to a local variable that is subsequently never used, which seems inefficient. I enjoy the very reasonable fact that instance variables are nil before assignment, but I'd like for the situation to be just as easy for local variables.

  • Can I Copy All the Wikis From One Trac To Another?

    - by William Leara
    We have an existing Trac installation for an old bunch of source code, and I'm creating a new Trac installation to support a new bunch of source code. Most of the info we've built up over time in the old Trac installation's wiki is equally relevant for the new Trac wiki. Is there a quick way to migrate the wiki data from the old Trac to the new Trac? Trac version = 0.10.4

    - by r9r9r9
    I am writing a application that monitor the system's health, user should know when they need to defrag the volumes. What I am thinking is calling the "defrag.exe /A" then analyze the output result to see whether it contains "You do not need to defragment this volume." But it's slow and very bad, I fount that the "Analyze" is really quick on the MyDefrag.exe. Anyone could tell me what's the best and simplest way?

  • How to extract the lat/lng of pins in google maps?

    - by BCS
    I want to extract the latitude and longitude of a set of about 50-100 pins in a Google maps web page. I don't control the page and I don't need to do it more than once so I'm looking for something quick and dirty.
