  • Forum board example schema in YAML format - modify for Nested set?

    - by takeshin
    I have created a forum board app, based on YAML schema found in 'real world examples' of Doctrine Manual, which looks similar to this: --- Forum_Category: columns: root_category_id: integer(10) parent_category_id: integer(10) name: string(50) description: string(99999) relations: Subcategory: class: Forum_Category local: parent_category_id foreign: id Rootcategory: class: Forum_Category local: root_category_id foreign: id Forum_Board: columns: category_id: integer(10) name: string(100) description: string(5000) relations: Category: class: Forum_Category local: category_id foreign: id Threads: class: Forum_Thread local: id foreign: board_id Forum_Entry: columns: author: string(50) topic: string(100) message: string(99999) parent_entry_id: integer(10) thread_id: integer(10) date: integer(10) relations: Parent: class: Forum_Entry local: parent_entry_id foreign: id Thread: class: Forum_Thread local: thread_id foreign: id Forum_Thread: columns: board_id: integer(10) updated: integer(10) closed: integer(1) relations: Board: class: Forum_Board local: board_id foreign: id Entries: class: Forum_Entry local: id foreign: thread_id How to modify this schema, to use NestedSet (Tree structure of threads and entries)?

  • Adding a search box to a windows forms web browser control that highlights text

    - by evan
    I have a windows forms (using c#) application. It displays a webpage and has a textbox/botton combination which can be used to search for text displayed to the user. Currently I search the inner text of all elements for the text in the textbox. And then I weed out the elements that are redundant (for example a word could be in a 'p' and 'b' element where the 'b' is a child element of 'p' so the element returned should be 'b'). Finally I run the ScrollIntoView(true) method on the found element. I'd now like to add a function that highlights the text (like if you search for a term in a real webbrowser). My first thought was to just inject html and or javascript code around the text but that seems like a messy solution. Any ideas on how I should do this? Thanks for your help!

  • Geocoding service for a startup?

    - by Sologoub
    I'm working on an idea for a service that uses geocoded data (lat/lng) form a US address. Google maps API v3 has been awesome, until I read the terms of service and acceptable uses a little closer. The problem is that the terms seem to prohibit use of the maps API for any commercial use where the site is not freely accessibly to the public, such as a subscription based service. The alternative offered is Google Maps API Premier, but at $10,000 per year minimum, it's just not possible at this time. Same goes for services offered by Yahoo! and MS - initial fees are small for enterprises, but for a very early stage startup (not even a finished prototype yet!) it's just not doable. Geocoding process needs to be real-time and volume would be very small - user would enter address at setup time and only update it if needed. Any help is greatly appreciated!

  • Which set(s) of video lectures for computer science?

    - by SebKom
    As most of you know a couple of top universities (MIT, Stanford, etc) around the world are now publishing videos of their lectures online. I am advancing to the third and final year of my computer science degree this September and I was thinking about spending some time during the summer to watch a couple of lectures, in order to improve my understanding of algorithms, complexity, programming, software engineering, etc. Now I don't have infinite time to spend so I can't watch all of the lectures from all of the universities so I was wondering if you could suggest me which sets to watch from each one (something like "Algorithms from MIT", "Programming from Yale", etc).

  • Web programming: Apache modules: mod_python vs mod_php

    - by Olivier Pons
    Hi! I've been using for more than 12 years PHP with Apache (a.k.a mod_php) for my web development work. I've recenlty discovered python and its real power (I still don't understand why this is not always the best product that becomes the most famous). I've just discovered mod_python for Apache. I've already googled but without success things like mod_python vs mod_php. I wanted to know the differences between the two mod_php and mod_python in terms of: speed productivity maintainance (I know `python is most productive and maintainable language in the world, but is it the same for Web programming with Apache) availability of features e.g, cookies and session handling, databases, protocols, etc.

  • Working effectively unit tests / Anyone tried the in-assembly approach?

    - by CodingCrapper
    I'm trying to re-introduce unit testing into my team as our current coverage is very poor. Our system is quite large 40+ projects/assemblies. We current use a project named [SystemName].Test.csproj were all the test code is dumped and organised to represent the namespaces using folders. This approach is not very scalable and makes it difficult to find tests. I've been thinking about added a Tests folder to each project, this would put the unit tests "in the developers face" and make them easy to find. The downside is the Production release code would contain references to nunit, nmocks as well as the test code and test data.... Has anyone tried this approach? How is everyone else working with unit tests on large projects? Having a Tests project per "real" project/assembly would introduce too many new projs. Thanks in advance

  • How I can use the HTTP headers to indicate in the Response that possibility?

    - by Cris Hong Kong CRISHK
    Finally I accomplished to cache dynamic images, css, and javascript files using HTTP headers BUT I have a problem now: I have specific dynamic images that are equal but has different URL's. For example: http://example.com/image/src/the-same-image.jpg http://example.com/image/custom/src/the-same-image2.jpg 1 and 2 has the same file content but different URL. This is a problem now because the navigator assumes that the file are different and need to be cached (due to the URL), when the real cached file is only one. I have the possibility to know if the file at the URL's are the same. How I can use the headers to indicate in the Response that possibility, and the navigator will cache only one file?

  • Highlight polygon and tint rest of map using Google Maps

    - by Haes
    Hi, I'd like to display a highlighted polygon using Google Maps. The idea is that the polygon in question would be displayed normally and the rest of the map should be darkened a little bit. Here's an example image what I would like to accomplish with a polygon from Austria: Unfortunately, I'm a complete rookie when it comes to Google Maps API's and map stuff in general. So, is this even possible do this with Google Map API's? If yes, with what version (v2, v3)? Would it be easier to do it with other map toolkits, like openlayers? PS: One idea I had, was to build an inverse polygon (in this example, the whole world minus the shape of austria) and then display a black colored overlay with transparency using this inverted polygon. But that seems to be quite complicated to me.

  • More elegant way to make a C++ member function change different member variables based on template p

    - by Eric Moyer
    Today, I wrote some code that needed to add elements to different container variables depending on the type of a template parameter. I solved it by writing a friend helper class specialized on its own template parameter which had a member variable of the original class. It saved me a few hundred lines of repeating myself without adding much complexity. However, it seemed kludgey. I would like to know if there is a better, more elegant way. The code below is a greatly simplified example illustrating the problem and my solution. It compiles in g++. #include <vector> #include <algorithm> #include <iostream> namespace myNS{ template<class Elt> struct Container{ std::vector<Elt> contents; template<class Iter> void set(Iter begin, Iter end){ contents.erase(contents.begin(), contents.end()); std::copy(begin, end, back_inserter(contents)); } }; struct User; namespace WkNS{ template<class Elt> struct Worker{ User& u; Worker(User& u):u(u){} template<class Iter> void set(Iter begin, Iter end); }; }; struct F{ int x; explicit F(int x):x(x){} }; struct G{ double x; explicit G(double x):x(x){} }; struct User{ Container<F> a; Container<G> b; template<class Elt> void doIt(Elt x, Elt y){ std::vector<Elt> v; v.push_back(x); v.push_back(y); Worker<Elt>(*this).set(v.begin(), v.end()); } }; namespace WkNS{ template<class Elt> template<class Iter> void Worker<Elt>::set(Iter begin, Iter end){ std::cout << "Set a." << std::endl; u.a.set(begin, end); } template<> template<class Iter> void Worker<G>::set(Iter begin, Iter end){ std::cout << "Set b." << std::endl; u.b.set(begin, end); } }; }; int main(){ using myNS::F; using myNS::G; myNS::User u; u.doIt(F(1),F(2)); u.doIt(G(3),G(4)); } User is the class I was writing. Worker is my helper class. I have it in its own namespace because I don't want it causing trouble outside myNS. Container is a container class whose definition I don't want to modify, but is used by User in its instance variables. doIt<F> should modify a. doIt<G> should modify b. F and G are open to limited modification if that would produce a more elegant solution. (As an example of one such modification, in the real application F's constructor takes a dummy parameter to make it look like G's constructor and save me from repeating myself.) In the real code, Worker is a friend of User and member variables are private. To make the example simpler to write, I made everything public. However, a solution that requires things to be public really doesn't answer my question. Given all these caveats, is there a better way to write User::doIt?

  • Virtual machine on ubuntu [closed]

    I have configured virtual machine on ubuntu with the help of below article, https://help.ubuntu.com/9.04/serverguide/C/libvirt.html I managed to finish all the part except the major portion getting virtual host to talk to real network, Which I guess should be done only via bridge interface. Via virtual machine manager I try to choose any interface it gives me interface not bridged When I try to bridge the interceface eth0 as below auto br0 iface br0 inet static address 192.168.0.223 network 192.168.0.0 netmask 255.255.255.0 broadcast 192.168.0.255 gateway 192.168.0.1 bridge_ports eth0 bridge_fd 9 bridge_hello 2 bridge_maxage 12 bridge_stp off I cannot communicate with this interface to network, host server looses all the communication to network. But when I remote bridge interface from /etc/network/interfaces And configure eth0 as below it works fine The primary network interface auto eth0 iface eth0 inet static address 192.168.0.223 netmask 255.255.255.0 network 192.168.0.0 broadcast 192.168.0.255 dns-nameservers 62.215.6.51 gateway 192.168.0.1 how can i setup bridge interface correctly and how would my /etc/netwrok/interfaces file would look a like.

  • can you use proxies to do load/stress testing on a server, with proxy serving as a sort of mirror?

    - by EndangeringSpecies
    suppose I want to test a server's and its web application's ability to handle many simultaneous connections well and show decent latency. So ideally I would want a thousand machines to bombard it with usage requests, but that's not practicable. So instead, can I just make a testing script with a thousand threads to run on the same server and have them perform the testing, connecting to the server via a geographically far-away proxy? My reasoning here is that the signal will have to travel realistically big distances to the proxy and back, so that sort of emulates the reality of real clients accessing the server. Then again, to take this one step further, are there prepackaged emulators/frameworks that could perform a similar test without using internet at all, just simulating the latency of the network, realistically creating all the socket connections and other resource intensive stuff etc?

  • Handling user security scope with nHibernate or other ORM

    - by Schotime
    How should one handle the situation where you may need to filter by a group of users. Here is the scenario. I have an administrator role in my company. I should be able to see all the data belonging to me plus all the other users who I have control over. A plain old user however should only be able to access their own data. If you are writing regular sql statements then you can have a security table with every user and who they have access too but i'm not sure how to handle this situation in the OO and ORM world. Any one dealt with this scenario in a web application using an ORM? Would love to hear your thoughts!

  • Understand ACTV mode and the PORT command

    - by Ramy
    Hello, I'm the part time FTP server administrator (with no real full-time admin). We currently only allow ACTV mode connections. Some of our clients have had issues with this but for the most part they've been ok using ACTV. For the few who aren't, we've been able to push the data over to their servers from ours. there is one client in particular however who is currently having trouble. He is using file-zilla and issuing a PORT command. First, does using the PORT command imply that you are in ACTV mode? Second is there a way in FileZilla to explicitly change to ACTV mode? Thanks for the help, _Ramy

  • Magento Design Patterns

    - by JonB
    Magento, IMHO, represents a PHP system that is built on well thought-out coding principles - reuseable design patterns being one of them. In terms of an example of a PHP system, I think it can be considered pretty cutting edge and therefore worth considering from an architectural point of view. As I understand it, there are many design patterns that are available to the OOP developer. Seeing such patterns being put to use in an open-source system such as Magento allows a developer to view examples of such patterns in real use and in situ, rather than in examples that can sometimes be rather achedemic, and even a little misleading. As such, I am wondering what patterns, other than the ones I have listed below, Magento programmers have used when developing for Magento. As a note, I understand that some of these patterns are in place as a consequence of being built on the Zend Framework, MVC / Front Controller being a couple of them, The obvious ones are: Factory: $product = Mage::getModel('catalog/product'); Singleton: $category = Mage::getSingleton('catalog/session'); Registry: $currentCategory = Mage::registry('current_category');

  • awk / sed script to remove text

    - by radman
    Hi, I am currently needed of way to programmatically remove some text from Makefiles that I am dealing with. Now the problem is that (for whatever reason) the makefiles are being generated with link commands of -l<full_path_to_library>/<library_name> when they should be generated with -l<library_name>. So what I need is a script to find all occurrences of -l/ and then remove up to and including the next /. Example of what I'm dealing with -l/home/user/path/to/boost/lib/boost_filesystem I need it to be -lboost_filesystem As could be imagined this is a stop gap measure until I fix the real problem (on the generation side) but in the meantime it would be a great help to me if this could work and I am not too good with my awk and sed. Thanks for any help.

  • Will dynamicaly generated content via Javascript hurt SEO

    - by Luke101
    This is what I would like to do. I would like to load content dynamically. Everything except the actual content will be rendered by javascript. I will place all the require information in a javascript variable or array at the bottom of the page. Then I will use javascript to place the content in the designated area. These are the types of things I would like javascript to render: Login menu Header and logo info Side bar info Footer info Dialog popups Ads All of the MEAT content will not be rendered by javascript. I will use the backend server to put the content in html. My logic is that more of the real content will be in HTML and all the other things will be rendered by javascript. Will this help or hurt SEO?

  • install CakePHP on Mac osx: apache problems

    First time cake user and I'm having real apache problems. For some reason the .htaccess is trying to find File does not exist: /Library/WebServer/Documents/Users but there is no such directory as Users.

  • Time order of messages

    - by Aiden Bell
    Read (skimmed enough to get coding) through Erlang Programming and Programming Erlang. One question, which is as simple as it sounds: If you have a process Pid1 on machine m1 and a billion million messages are sent to Pid1, are messages handled in parallel by that process (I get the impression no) and(answered below) is there any guarantee of order when processing messages? ie. Received in order sent? If so, how is clock skew handled in high traffic situations for ordering? Coming from the whole C/Thread pools/Shared State background ... I want to get this concrete. I understand distributing an application, but want to ensure the 'raw bones' are what I expect before building processes and distributing workload. Also, am I right in thinking the whole world is currently flicking through Erlang texts ;)

    The classical C program is something like: int main() { fprintf(stderr, "hello world\n"); } a classical OpenGL program is: open up a window setup ortho view draw a colored triangle Now, I want to do the most basic thing for sound in Linux. I want to: 1) open up speakers 2) send a bunch of data, meant to be interpreted at 40Khz, 3) have pseakers play said data no midi, no instruments, ... just playing back raw data What is the easiest way to do this in a C program? [and what libraries; what's the equiv to OpenGL for sound?] Thanks!

  • Developing browser plug-ins?

    - by JavaMan
    I have a project that I'd like to try that involves developing an internet browser plug-in. I have knowledge in Java and DHTML, but nothing in the world of browser plug-in development. I thought I would just ask here then what is the most efficient way to develop a browser plug-in? If possible, I'd like to streamline the process so that getting the plug-in to work in different browsers involves as little work as possible. Can this be done? I'm not asking for a tutorial like the trolls do, just a few pointers that's all. I don't waste mine or anyone else's time.

  • Finding final/effective web.config values (from inherited configurations)

    - by gregmac
    Are there any apps that can show the final configuration as applied to a particular application directory? What I'm picturing is something along the lines of FireBug's CSS viewer. Basically, it should show the equivalent single web.config file (as if you only had one), with all the values that apply to the directory in question, with each element (or even attribute) annotated with its source (the real .config file it came from). This would greatly help deploying applications into foreign environments (eg, customer sites) where they sometimes have strange configs, that add in global includes (eg, they put the include in machine.config, instead of the web.config for that app) or have allowOverride=false, etc.

  • How hard is it for a .NET programmer to learn Objective C and Cocoa?

    - by rsteckly
    Hi, I'm trying to build a dual platform application for a company of my own I'm trying to start at night. I have the .NET version done, but have not finished the UI part. I'm thinking of buying some 3rd party controls. If I buy these controls, however, they clearly will only work in my Windows version. I'm wondering if I should try to do the UI in GTK# and use Mono with CocoaSharp or just build the thing in MS technology and teach myself the Mac side? I'm just really unfamiliar with the Mac world and am wondering how much of a learning curve there might be. I've thought perhaps of rewriting my core logic in Ruby or Python. This why I could use the .NET version with .NET controls and presumably hook the same code up on the Mac. It's an educational app targeted at consumers. As such, it shouldn't require a lot of technical sophistication to install.

  • How to get or make a WPF WebBrowser with a visual.

    - by Trainee4Life
    Having problems related to WPF WebBrowser not having a visual. Reason being, that it actually a wrapper around the winforms browser. Anyways, I searched the web for any solution to this problem, and got hold of the following suggestions: http://chriscavanagh.wordpress.com/2009/08/25/a-real-wpf-webbrowser/ http://rob.runtothehills.org/archives/60 The first one solves everything, but seems like an overkill. Plus, the dll's should be licensed for commercial use. The second one seems simple, but not able to figure out when to refresh the screen. Plus there's so much to do like sending mouse and keyboard messages to the webbrowser. P.S. The problem I'm trying to solve is to show the same webbrowser on different windows. They both must be interactive, and always in sync visually.

How can I use jQuery to find the value of the hidden input type?
