  • Parsing complex string using regex

    - by wojtek_z
    My regex skills are not very good and recently a new data element has thrown my parser into a loop Take the following string "+USER=Bob Smith-GROUP=Admin+FUNCTION=Read/FUNCTION=Write" Previously I had the following for my regex : [+\\-/] Which would turn the result into USER=Bob Smith GROUP=Admin FUNCTION=Read FUNCTION=Write FUNCTION=Read But now I have values with dashes in them which is causing bad output New string looks like "+USER=Bob Smith-GROUP=Admin+FUNCTION=Read/FUNCTION=Write/FUNCTION=Read-Write" Which gives me the following result , and breaks the key = value structure. USER=Bob Smith GROUP=Admin FUNCTION=Read FUNCTION=Write FUNCTION=Read Write Can someone help me formulate a valid regex for handling this or point me to some key / value examples. Basically I need to be able to handle + - / signs in order to get combinations.

  • Higher than high-level web frameworks or CMS's?

    - by Ben
    I'm looking for options that allow very high-level web site development with these special characteristics: not requiring the user to program in a complex programming language not requiring the user to use GUI-like administration areas allow the user to "program" in a lightweight markup language The last point is not only about look and structure of the output but also about creating simple dynamic output. For example: listing pages fetching the content of other pages doing a site search and displaying its output dynamically show or hide parts of the page depending on login status Of course, I am not expecting a solution that provides the same possibilities like a Ruby, Python or PHP web framework. Rather I am looking for support of the "basics" that are common for web sites. Until now, I have found only one piece of software that fulfills these requirements but while it's free, it's not open source: BoltWire at http://www.boltwire.com/. Being open source is required.

  • speed up a sql query to mysql?

    - by fayer
    in my mysql database i've got the geonames database, containing all countries, states and cities. i am using this to create a cascading menu so the user could select where he is from: country - state - county - city. but the main problem is that the query will search through all the 7 millions rows in that table each time i want to get the list of children rows, and that is taking a while 10-15 seconds. i wonder how i could speed this up: caching? table views? reorganizing table structure somehow? and most important, how do i do these things? are there good tutorials you could link to me? i appreciate all help and feedback discussing smart ways of handling this issue!

  • Reinforcement learning with neural networks

    - by Betamoo
    I am working on a project with RL & NN I need to determine the action vector structure which will be fed to a neural network.. I have 3 different actions (A & B & Nothing) each with different powers (e.g A100 A50 B100 B50) I wonder what is the best way to feed these actions to a NN in order to yield best results? 1- feed A/B to input 1, while action power 100/50/Nothing to input 2 2- feed A100/A50/Nothing to input 1, while B100/B50/Nothing to input 2 3- feed A100/A50 to input 1, while B100/B50 to input 2, while Nothing flag to input 3 4- Also to feed 100 & 50 or normalize them to 2 & 1 ? I need reasons why to choose one method Any suggestions are recommended Thanks

  • C# dictionary uniqueness for sibling classes using IEquatable<T>

    - by anthony
    I would like to store insances of two classes in a dictionary structure and use IEquatable to determine uniqueness of these instances. Both of these classes share an (abstract) base class. Consider the following classes: abstract class Foo { ... } class SubFoo1 : Foo { ... } class SubFoo2 : Foo { ... } The dictionary will be delcared: Dictionary<Foo, Bar> Which classes should be declared as IEquatable? And what should the generic type T be for those declarations? Is this even possible?

  • Seeking tuturial: introduction to ODBC with Delphi

    - by mawg
    I have a lot of embedded C/C++/Ada experience and an outdated smattering of Delphi plus some database stuff. Now I have to implement an app in Delphi which can manipulate MySql, Oracle, maybe MS Acess. In short, I need ODBC. I need to programatically created a database, define its structure and populate its contents, then later query its existence and programatically search. I would prefer not to use 3rd party components, unless there is a compelling reason to do so (performance ought not to be an issue for the app, it won't have much data or be run often, at least not in v1.0) . Can anyone point me at a tutorial which can get me up to speed? Thanks

  • Counting number of children in hierarchical SQL data

    - by moontear
    for a simple data structure such as so: ID parentID Text Price 1 Root 2 1 Flowers 3 1 Electro 4 2 Rose 10 5 2 Violet 5 6 4 Red Rose 12 7 3 Television 100 8 3 Radio 70 9 8 Webradio 90 For reference, the hierarchy tree looks like this: ID Text Price 1 Root |2 Flowers |-4 Rose 10 | |-6 Red Rose 12 |-5 Violet 5 |3 Electro |-7 Television 100 |-8 Radio 70 |-9 Webradio 90 I'd like to count the number of children per level. So I would get a new column "NoOfChildren" like so: ID parentID Text Price NoOfChildren 1 Root 8 2 1 Flowers 3 3 1 Electro 3 4 2 Rose 10 1 5 2 Violet 5 0 6 4 Red Rose 12 0 7 3 Television 100 0 8 3 Radio 70 1 9 8 Webradio 90 0 I read a few things about hierarchical data, but I somehow get stuck on the multiple inner joins on the parentIDs. Maybe someone could help me out here. moon

  • How do you unit test web page authorization using ASP.NET MVC?

    - by Kevin Pang
    Let's say you have a profile page that can only be accessed by the owner of that profile. This profile page is located at: User/Profile/{userID} Now, I imagine in order to prevent access to this page by other users, you could structure your UserController class's Profile function to check the current session's identity: HttpContext.Current.User.Identity.Name If the id matches the one in the url, then you proceed. Otherwise you redirect to some sort of error page. My question is how do you unit test something like this? I'm guessing that you need to use some sort of dependency injection instead of the HttpContext in the controller to do the check on, but I am unclear what the best way to do that is. Any advice would be helpful.

  • Level-order in Haskell

    - by brain_damage
    I have a structure for a tree and I want to print the tree by levels. data Tree a = Nd a [Tree a] deriving Show type Nd = String tree = Nd "a" [Nd "b" [Nd "c" [], Nd "g" [Nd "h" [], Nd "i" [], Nd "j" [], Nd "k" []]], Nd "d" [Nd "f" []], Nd "e" [Nd "l" [Nd "n" [Nd "o" []]], Nd "m" []]] preorder (Nd x ts) = x : concatMap preorder ts postorder (Nd x ts) = (concatMap postorder ts) ++ [x] But how to do it by levels? "levels tree" should print ["a", "bde", "cgflm", "hijkn", "o"]. I think that "iterate" would be suitable function for the purpose, but I cannot come up with a solution how to use it. Would you help me, please?

  • Create automatically table that is composed by its primery key and 2 other foreign keys

    - by user210481
    I have table A with a primary id, a table B with a primary key id also and another table C with a primary key id and rows Aid and Bid where Aid and Bid are foreign keys of C and the primary keys of A and B respectively. One way of populating these DB would be populating table A, table B and table C separately. I would like to know if there is a more clever way of doing it, where I could populate A first and at the same time I populate B, I can indicate that an entry in C should be also created. Any idea and suggestion on how to populate them is welcome. I'm trying to take advantage of the foreign keys structure Thanks

  • PHP pecl/memcached extension slow when setting option for consistent hashing

    - by HarryF
    Using the newer PHP pecl/memcached extension. Calls to Memcached::setOption() like; $m = new Memcached(); $m->setOption(Memcached::OPT_DISTRIBUTION, Memcached::DISTRIBUTION_CONSISTENT); are costing between 150 to 500ms - just in making the call to setOption() and as we're not using persistent connections but rather doing this on every request, it hurts. Delving deeper, setting Memcached::OPT_DISTRIBUTION to Memcached::DISTRIBUTION_CONSISTENT ends up calling update_continuum() in libmemcached which appears to be fairly intensive, although we're only passing a list of 15 memcached servers in, so somewhat surprising to see it take between 150 to 500ms to rebuild the continuum data structure. Could it be setting this option is only suitable for persistent connections, where it's called only once while making the initial connection? Or is this a bug libmemcached? Using the newer pecl/memcached extension 1.0.1 with libmemcached 0.38 Thanks.

  • How to create a typed stack using Objective-C

    - by Xetius
    I can create a stack class quite easily, using push and pop accessor methods to an NSArray, however. I can make this generic to take any NSObject derived class, however, I want to store only a specific class in this stack. Ideally I want to create something similar to Java's typed lists (List or List) so that I can only store that type in the stack. I can create a different class for each (ProjectStack or ItemStack), but this will lead to a more complicated file structure. Is there a way to do this to restrict the type of class I can add to a container to a specific, configurable type?

  • How to document an XML Schema?

    - by lucas clemente
    I have developed a XML schema for an application I wrote. Now I want to document the valid structure for the end user, however I can't come up with any natural way to do this. I've seen things like xs3p, which essentially converts a xsd schema to a HTML representation, however that doesn't look like good documentation to me; the user shouldn't need to know anything about schemas to understand what he is allowed to do. Any ideas how to document this? Any programs / editors / graphical solutions or simply concepts I can build on?

  • Create MSI for slipstream SQL 2008 install

    - by Graham
    I am looking at creating an MSI that will check/install the prerequisites of SQL Server 2008 and after the prerequisites are installed I will start my slipstream 2008 install. I am currently trying to do this through VS 2008 Deployment Projects, but I cannot just simple add the folders of the SQL slipstream into the setup project without recreating the entire folder structure of the SQL install. So my questions are: Is this a possible to do through Deployment Projects? (if yes, please assist with links or help) Is there a better way to do this? (I would prefer not to use WISE)

  • Batch build using IAR tools

    - by Jim Tshr
    I am trying to do a batch build of a project using IAR tools. The processor is a CC2530, and it builds fine in the IDE. I have followed the documentation for batch build (Project/Batch Build) and created a .cspy file that is suppose to be my batch file, but in the comments in that file it indicates that I need a debug file (.ubrof) to execute with it. I can't find a .ubrof file and I have searched the whole project directory structure. Also, I want my batch build to build a production version without the debugging information. Where do I get a .ubrof file? How do I do a production batch build using IAR tools?

  • Why does forward declaration not work with classes?

    - by eSKay
    int main() { B bb; //does not compile (neither does class B bb;) C cc; //does not compile struct t tt; //compiles class B {}; struct s { struct t * pt; }; //compiles struct t { struct s * ps; }; return 0; } class C {}; I just modified the example given here. Why is that the struct forward declarations work but not the class forward declarations? Does it have something to do with the namespaces - tag namespace and typedef namespace? I know that the structure definitions without typedefs go to tag namespace. Structures are just classes with all public members. So, I expect them to behave similarly.

  • Pros and cons of programmatically enforcing foreign key than in database

    - by Jeffrey
    It is causing so much trouble in terms of development just by letting database enforcing foreign key. Especially during unit test I can’t drop table due to foreign key constrains, I need to create table in such an order that foreign key constrain warning won’t get triggered. In reality I don’t see too much point of letting database enforcing the foreign key constrains. If the application has been properly designed there should not be any manual database manipulation other than select queries. I just want to make sure that I am not digging myself into a hole by not having foreign key constrains in database and leaving it solely to the application’s responsibility. Am I missing anything? P.S. my real unit tests (not those that use mocking) will drop existing tables if the structure of underlying domain object has been modified.

  • Flex: Get an item from a AdvancedDataGrid given an index

    - by David Wolever
    I've got a subclass of AdvancedDataGrid showing a tree-like data structure. How can I, given the index returned by calculateDropIndex, get the item at that index? After reading through reams of code, it seems like the least terrible way is: var oldSelectedIndex:int = this.selectedIndex; var mouseOverIndex:int = this.calculateDropIndex(event); this.selectedItem = mouseOverIndex; var item:* = this.selectedItem; this.selectedIndex = oldSelectedIndex; The other option seems to be tinkering around with the iterator property... But, judging by the way I've seen it used, that will get pretty harry pretty quickly too. So, how can I get the item at a particular index in an advanced datagrid without going insane?

My solution structure looks like this: Solution |-Content |-Controllers |-Models |-Views |-etc... |-Reports |-Default.aspx |-Report.rpt On the server, the Report.rpt file is missing after I publish.

  • jQuery hoverIntent not working, but hover does

    - by kylex
    I have the following code: $(document).ready(function(){ $(".yearInner").hide(); $(".year", this).hover( function () { $(".yearInner", this).slideToggle(); } ); }); It hides the div with class yearInner, and then when the containing div with class year is hovered over, the yearInner div toggles on. Works fine, put I'd like to use the hoverIntent plug-in instead of hover. Doesn't work at all with hoverIntent. Suggestions? Div structure for reference: <div class="year"> 2009 <div class="yearInner"> More Info... </div> </div> <div class="year"> 2008 <div class="yearInner"> More Info... </div> </div>

  • ServletContext getResource not working

    - by David
    I'm trying to use ServletContext.getResource to retrieve a java.net.url reference to an image file (which I will then include in a PDF library using iText). When I use ServletContext.getRealPath("picture.jpg"), I get back a string URL. However, getResource always returns null. Example 1: String picture = ServletContext.getRealPath("picture.jpg"); // picture contains a non-null String with the correct path URL pictureURL = ServletContext.getResource(picture); // pictureURL is always null Example 2: URL pictureURL = ServletContext.getResource("picture.jpg"); // pictureURL is always null So what is the correct way to build a java.net.URL object pointing to a file in my webapps folder? Why does getRealPath work but not getResource? In case it helps at all, here is my folder structure webapps - mySite - picture.jpg Does my picture need to be stored in either WEB-INF or WEB-INF/classes to be read by getResource?
