  • Can you recommend wiki, forum, blog & cms plugins for an existing Rails app or should I go the route

    - by Nick Gorbikoff
    Hello. I have an existing Rails internal app, that handles inventory, invoicing, order taking, labeling, data imports/exports, etc, etc. Now I need to add blog, cms, forum and wiki functionality to it. It seems silly to try to roll out my own solutions when there are already some out there. So I was wondering if people could recommend based on their experience: Are there good plugins out there? (Which ones you had experience with?) Would you rather recommend to go the route of engines, and integrate RadiantCMS or similar apps? (please provide recommendations based on your integration experience) Or would you just bite the bullet and roll out your own? Thank you. P.S.: Right now the app is Rails 2.3, but it will get upgraded to Rail 3 in a year, when most gems/plugins that it depends on will be Rails 3 compatible.

  • .NET application with an Oracle Database

    - by Pavitar
    I have to code a desktop application and some dynamic web content. I'm planning to develop it in .NET with an Oracle database, though my dilemma is that my professor says that if I do so, there would be a lot of support issues later on. He says .NET is more compatible with MS SQL and MS Access, and so is the trend, everyone does it.Is it true? I have learnt Oracle so I know of a few features which I wouldn't be able to implement on SQL comfortably because of lack of knowledge of SQL databases.I would love to learn the new syntax but again, I don't have much time to spare.

  • Why does Ruby 1.9.2 remove "." from LOAD_PATH, and what's the alternative?

    - by John Feminella
    The latest changesets to Ruby 1.9.2 no longer make the current directory . part of your LOAD_PATH. I have a non-trivial number of Rakefiles that assume that . is part of the LOAD_PATH, so this broke them. Was there a particular justification for doing this? As for a fix, adding $: << "." everywhere works, but seems incredibly hacky and I don't want to do that. What's the preferred way to make my Rakefiles 1.9.2+ compatible?

  • Possible to create JSR 286 portlet using Coldfusion?

    - by Jakub
    I was just thinking this morning, since ColdFusion is essentially built on JAVA, is it possible to create JSR 286 portlets using coldfusion? A search revealed that it might be possible, but I cannot find any material on this? Reason I ask is because I would love to be able to create Liferay compatible portlets with ColdFusion, as I am not a JAVA dev. Thoughts? Does anyone have any tutorials or references on this subject? EDIT Is there anyways to get CF portlets without CF running in the container? I'm curious how this would work with having only one license of CF. Would I need another license to run under liferay (if I can even run in liferay?)

  • Using ECF shared editing with Python

    - by hekevintran
    I can use the shared editing feature of ECF with Java fine perfectly fine. When I try to do it with Python files it also works, but there is no syntax highlighting. I installed PyDev to get syntax highlighting, but then the context menu does not have the "share editor" option. I removed PyDev and the option came back. I installed Dynamic Languages Toolkit in hopes that its Python syntax highlighting was compatible and I got the same effect (context menu lacks the "share editor" option). Is there a way to have a shared editing session with Python files and syntax highlighting?

    - by Paul Tarjan
    I'm building a browser extension that will insert a chunk of HTML into some pages. I'd like the page's CSS to not apply to this section. What is the best way to do this? Is there a good reset I can put on the root element of my HTML and set it to !important so it gets applied after others?

  • have a width larger than 960px with 960?

    - by noname
    if i use the custom css generator on their webpage i can have a wider width than 960? so isnt the name 960 kind of misleading? and some persons say that you cant have a flexible grid system (that changes with your browser size) with 960. but you can download a fluid version from the custom css generator. so apparently they didnt know what they were talking about? would be great if someone could straight these things out.

  • Multiple EyeFinity Display groups

    - by Shinrai
    Is it possible with an EyeFinity enabled card to make multiple display groups at once? I was playing with a FirePro 2460 and while a 4x1 or 2x2 display group works quite nicely, if I make a 2x1 display group and then select one of the other displays to try to make a second 2x1 display group, it disables the first one. Is there any way to circumvent this behavior and set up two separate spans on the same card? Additionally, can you set up distinct display groups if they're on different cards? I will have the opportunity to test several of these cards in one machine very shortly, but I'm curious if anyone has any experience. EDIT: I can confirm that you can make multiple spans on multiple cards (as long as they don't cross cards, obviously) (If the answers are different for FirePro/FireMV cards and Radeon cards, that is helpful and relevant knowledge - I doubt it, though.)

  • Calling C++/CLI Method with System::DateTime parameter requires 'ValueType' as a parameter?

    - by David Ipsen
    I'm attempting to call a method written in C++/CLI from C#. The C++/CLI code is used to update a TIMESTAMP column in an Oracle database, given a record ID and the System::DateTime object which is the .NET compatible data type for Oracle's TIMESTAMP type. The method I am calling has the following prototype: bool ChangeJobUpdateDate (int jobIdIn, System::DateTime^ updateDateIn) I've added a reference to this DLL project in a test project that I made; I'm writing the tests in C#. However, when I try to call this method from the C# unit test project, the function appears to have the following method declaration (via intellisense): bool ChangeJobUpdateDate (int jobIdIn, ValueType updateDateIn) I'm admittedly not that familiar with C++/CLI, so is there something I'm missing?

  • Synergy doesn't work correctly if I switch client/server role (left of works, right of does not)

    - by PhilW
    When I use my win7/64bit as a server, with the mac (10.7.5) on its left, it works. Screens: [Mac/10.7.5]---[Win7/64bit] I've now switched the roles, so I use the Mac's keyboard (because Bug #18/19) and use windows as a client. Now I cannot move the mouse over the right edge to the windows client. But if I configure windows to be on the left (virtually at least), it works, I can use the left edge to cross over to the windows client. Dock is on the bottom. Synergy v1.4.15 What do I need to change in order to fix this? Thanks!
