  • One-line expression to map dictionary to another

    - by No Such IP
    I have dictionary like d = {'user_id':1, 'user':'user1', 'group_id':3, 'group_name':'ordinary users'} and "mapping" dictionary like: m = {'user_id':'uid', 'group_id':'gid', 'group_name':'group'} All i want to "replace" keys in first dictionary with keys from second (e.g. replace 'user_id' with 'uid', etc.) I know that keys are immutable and i know how to do it with 'if/else' statement. But maybe there is way to do it in one line expression?

  • How to design the application to conform to the n-tier architecture? (Winform sample in .net with li

    - by AlexRednic
    Rather a simple question. But the implications are vast. Over the last few weeks I've been reading a lot of material about n-tier architecture and it's implementation in the .NET world. The problem is I couldn't find a relevant sample for Winforms with Linq (linq is the way to go for BLL right?). How did you guys manage to grasp the n-tier concept? Books, articles, relevant samples etc.

  • Git: submodule init and update from different folder

    - by jmccartie
    Trying to write a deployment script, working on a repo in a different path. The "git-dir" flag seems to work fine for most commands, but not for submodule work. Am I missing a path directive? Works: git --git-dir=/tmp/repo_path/.git log Doesn't work: git --git-dir=/tmp/repo_path/.git submodule init Error: No submodule mapping found in .gitmodules for path 'path_to/submodule' Much thanks for any help.

  • Best practice to maintain source code under version control with multiple companies?

    - by lastcosmonaut
    Hey, I'm wondering if there is any best practice for maintaining your source code under version control among different companies. In Open Source there is a maintainer, who receives patches, decides on them and applies them. But what about closed sourced projects where different companies get different workloads and just commit them to the trunk and branches? Is this maintainer concept applicable to a project on which multiple companies work on?

  • Object Oriented vs Relational Databases

    - by Dan
    Objects oriented databases seem like a really cool idea to me, no need to worry about mapping your domain model to your database model, no messing around with sql or ORM tools. The way I understand it, relational DBs offer some advantages when there is massive amounts of data, and searching an indexing need to be done. To my mind 99% of websites are not massive, and enterprise issues never need to be thought about, so why arn't OO DBs more widely used?

  • Swiz Framework and Spring Framework - Are they related?

    - by theband
    I was looking into Swiz framework and i felt the same of Spring. Just i felt the difference between these two is one is JAVA based and the other is Action Script based. http://swizframework.org/ http://www.springsource.org/ My Question is: Does the goal of the both framework is same? Does the pattern they apply is same or different? The concept of beans, dependency injection and IOC lies in both.

  • Save all file names in a directory to a vector

    - by Bobby
    I need to save all ".xml" file names in a directory to a vector. To make a long story short, I cannot use the dirent API. It seems as if C++ does not have any concept of "directories". Once I have the filenames in a vector, I can iterate through and "fopen" these files. Is there an easy way to get these filenames at runtime?

  • How can I map UIDs to user names using Perl library functions?

    - by Mike
    I'm looking for a way of mapping a uid (unique number representing a system user) to a user name using Perl. Please don't suggest greping /etc/passwd :) Edit As a clarification, I wasn't looking for a solution that involved reading /etc/passwd explicitly. I realize that under the hood any solution would end up doing this, but I was searching for a library function to do it for me.

  • What's the difference between C and C++

    - by Dinah
    I know that C++ has the concept of objects but C doesn't. I also know that pretty much all there is to know about C fits into K & R but the C++ library is vastly more complex. There have got to be other big differences though. What are the major differences between C and C++?

  • Network IO using Credentials

    - by John
    Is it possible to move files from a network location that requires credentials to another network location that also requires credentials without mapping any drive. (ie: Without any use of P/Invoke) Example: FileInfo fi = new FileInfo(@"\\SomeComputer\SomeDrive\SomeFolder\someFile.txt"); fi.MoveTo(@"\\AnotherComputer\AnotherDrive\AnotherFolder\AnotherFile.txt"); This works fine if the source and destination network drives are already mapped but if they are not It doesn't.

  • a good resource or book for architecting object-oriented software

    - by Ygam
    I have looked at a couple of books and all I have looked at were just discussing the technicalities of OOP. By technicalities I mean, here's a concept, here's some code, now get working. I have yet to see a book that discusses the architectural process, what are the ways of doing this, why doing this is bad, how to actually incorporate design patterns in a real-world project, etc. Can you recommend a good resource or book? I am mainly programming with PHP but a language-agnostic book/resource would do :)

  • Finding existing tickets before opening new ones on trac

    - by Jens Jansson
    We're using Trac as the task management tool at the project we work in. However, Trac search is maybe not the most intuitive search out there, and we end up having multiple duplicates as the reporters can't effectively find if there already is a reported ticket of the question he or she found. Stack Overflow's "Related Questions" concept is great and works magnificently! I was wondering if someone has heard of some similar plugin to Trac, or if you have solved this problem some other way.
