  • A Question About the Expressive Power of Higher-Order Logical Reasoning Formalisms.

    - by Bubba88
    Hi! I do not really know if this is scientifically proven, but I've read in a book (It was a relatively modern AI book by Peter Norvig) that secon-order logical programming could be more expressive than existing first-order languages. The question is: Is it statistically/symbolically proven that higher-order predicate logics exceed first-order predicates in their expressive power? Or they just bring the modularity/convenience/maintainability to your knowledge bases? Additionally: If there is some kind of firm direction in which I could go seeking more expressive power than I have (I mean exactly the descriptive potential of the symbols I write in given semantics/syntax) - then I would be glad to hear just almost everything :) Thank you.

  • Identifying PHP unused variables (in Emacs)?

    - by Roberto Aloi
    Is it somehow possible to identify unused variables in a PHP file in Emacs? With other languages, this is possible by using tools such as flymake. I've already enabled Flymake to show syntax errors for my PHP files on the fly, but still it's frustrating that PHP logic errors are sometimes due to situations like: <?php $foo = whatever(); $bar = something($fo); ... Note the typo on $foo that will contribute to the developer's headache and to his exorbitant use of coffee.

  • Howto write a class where a property can be accessed without naming it.

    - by SchlaWiener
    I have a (dump) question regarding VB/C# I often use third party classes where I can access a child object with only specifying the id or key. Example: Instead of writing: DataRow row = GetAPopulatedDataRowSomeWhere(); Object result = row.Items[1]; // DataRow has no Items property Object result = row.Items["colName"]; // Also not possible I use this code to access the members: DataRow row = GetAPopulatedDataRowSomeWhere(); Object result = row[1]; Object result = row["colName"]; Can someone tell me how a class has to look like to support this syntax? My own class has a Dictionary that I want to access this way. MyClass["key"]; // <- that's what I want MyClass.SubItems["key"]; // <- that's how I use it now

  • A simple Python extension in C

    - by celil
    I am trying to create a simple python extension module. I compiled the following code into a transit.so dynamic module #include <python2.6/Python.h> static PyObject* _print(PyObject* self, PyObject* args) { return Py_BuildValue("i", 10); } static PyMethodDef TransitMethods[] = { {"print", _print, METH_VARARGS, ""}, {NULL, NULL, 0, NULL} }; PyMODINIT_FUNC inittransit(void) { Py_InitModule("transit", TransitMethods); } However, trying to call this from python import transit transit.print() I obtain an error message File "test.py", line 2 transit.print() ^ SyntaxError: invalid syntax What's wrong with my code?

  • maven-archetype-webapp eclipse problem

    - by Bruce
    Hi all, I'm trying to create a very simple webapp with maven and eclipse, but I'm having no joy at all, in fact the reverse of joy. I go to File - New Project, select Maven Project, and select the maven-archetype-webapp. When I finish the wizard, a webapp structure gets generated but with no 'java' directory under main, just resources and webapp. So I right click on main and select new Class. The class gets created under resources (?!), and furthermore, there seems to be no compilation of it by java. I can make stupid errors and no syntax highlighting comes up. It's like java isn't recognizing it. Alternatively I have tried creating a new 'java' directory under main where it should be, but still with the same non-existent java symptoms. What gives? This is driving me insane.. Thanks all!

  • How to use a variable to specify filegroup in MSSQL

    - by gt
    I want to alter a table to add a constraint during upgrade on a MSSQL database. This table is normally indexed on a filegroup called 'MY_INDEX' - but may also be on a database without this filegroup. In this case I want the indexing to be done on the 'PRIMARY' filegroup. I tried the following code to achieve this: DECLARE @fgName AS VARCHAR(10) SET @fgName = CASE WHEN EXISTS(SELECT groupname FROM sysfilegroups WHERE groupname = 'MY_INDEX') THEN QUOTENAME('MY_INDEX') ELSE QUOTENAME('PRIMARY') END ALTER TABLE [dbo].[mytable] ADD CONSTRAINT [PK_mytable] PRIMARY KEY ( [myGuid] ASC ) ON @fgName -- fails: 'incorrect syntax' However, the last line fails as it appears a filegroup cannot be specified by variable. Is this possible?

  • Ruby vs Lua as scripting language for C++

    - by bl00dshooter
    I am currently building a game server (not an engine), and I want it to be extendable, like a plugin system. The solution I found is to use a scripting language. So far, so good. I'm not sure if I should use Ruby or Lua. Lua is easier to embed, but Ruby has a larger library, and better syntax (in my opinion). The problem is, there is no easy way I found to use Ruby as scripting language with C++, whereas it's very easy with Lua. Toughs about this? Suggestions for using Ruby as scripting language (I tried SWIG, but it isn't nearly as neat as using Lua)? Thanks.

  • AJAX with Ruby on Rails?

    - by Zachary
    This is probably a really dumb question with a simple answer but... I am working on a project where I need to use AJAX to send/receive information. I am using Ruby on Rails (which I am pretty new to), but rather than using the helper methods or the built in functionality in the 'defaults' Javascript file, I need to do this manually in my own Javascript. I believe that ultimately I will want to send a request with a JSON object, then have the controller return another JSON object containing the requested information. The problem is that I cannot seem to find the syntax for sending something to a specific controller method, with parameters, directly from Javascript - everything I Google ends up being tutorials for using the Rails AJAX helper methods.

  • .net, using PowerShell class to invoke a "[namespace.class]::method" style command

    - by Marco
    Hello, I created a powershell object via .net to invoke commands. When I invoke normal commands like 'Get-Process' I had no problems: ps.AddCommand("Get-Process").AddParameter(...).Invoke() but I'm not able to invoke a .net method with the syntax "[namespace.class]::method", just to make an example to invoke [System.IO.File]::Exists("c:\boo.txt"). I tried with ps.AddCommand("[System.IO.File]::Exists(\"c:\boo.txt\")").Invoke() ps.AddCommand("[System.IO.File]::Exists").AddArgument("c:\boo.txt\").Invoke() and some others. It always throws an exception which says that the command specified is not recognized. There is a way to invoke that type of command? Thanks

  • Help porting a bit of Prototype JavaScript to jQuery

    - by ewall
    I have already implemented some AJAX pagination in my Rails app by using the example code for the will_paginate plugin--which is apparently using Prototype. But if I wanted to switch to using jQuery for future additions, I really don't want to have the Prototype stuff sitting around too (yes, I know it's possible). I haven't written a lick of JavaScript in years, let alone looked into Prototype and jQuery... so I could use some help converting this bit into jQuery-compatible syntax: document.observe("dom:loaded", function() { // the element in which we will observe all clicks and capture // ones originating from pagination links var container = $(document.body) if (container) { var img = new Image img.src = '/images/spinner.gif' function createSpinner() { return new Element('img', { src: img.src, 'class': 'spinner' }) } container.observe('click', function(e) { var el = e.element() if (el.match('.pagination a')) { el.up('.pagination').insert(createSpinner()) new Ajax.Request(el.href, { method: 'get' }) e.stop() } }) } }) Thanks in advance!

  • E4X in ActionScript

    - by Brian Genisio
    Hey all, Looking at the E4X implementation in ActionScript, it occurs to me that they had to figure out how to do three things that I am not sure can be done within ActionScript regularly: Properties/Getters prefixed with @: var myAttribute = xmlPerson.@name; Nameless functions for filtering: xmlData.person.(/* predicate */) lambda syntax for predicates: xmlData.person.(@name == "Brian") So here is my question: Are these just one-off capabilities (much like Vector.<>) they put in just for E4X, therefore keeping out of reach for us? Or do we, as ActionScript developers, have access to these features? More specifically, I'd love to get access to the expression tree of that lambda predicate for my own code (not tied to the XML classes in any way). I figured out that this is called the "filter operator"... but I am not sure how to harness it. Not sure I can... since ActionScript does not allow for operator overloading :(

  • STORED PROCEDURE working in my local test machine cannot be created in production environment.

    - by Marcos Buarque
    Hi, I have an SQL CREATE PROCEDURE statement that runs perfectly in my local SQL Server, but cannot be recreated in production environment. The error message I get in production is Msg 102, Level 15, State 1, Incorrect syntax near '='. It is a pretty big query and I don't want to annoy StackOverflow users, but I simply can't find a solution. If only you could point me out what settings I could check in the production server in order to enable running the code... I must be using some kind of syntax or something that is conflicting with some setting in production. This PROCEDURE was already registered in production before, but when I ran a DROP - CREATE PROCEDURE today, the server was able to drop the procedure, but not to recreate it. I will paste the code below.

  • Implement a simple class in your favorite language.

    I'm doing this to learn syntax of different programming languages. So, how would you defined the following class along with with it's operations in your favorite programming language? Image generated by http://yuml.me/ And a main method or equivalent to invoke it: For instance, for Java it would be: ... public static void main( String [] args ) { Fraction f = new Fraction(); f.numerator( 2 ); f.denominator( 5 ); f.print(); } ....

  • Combining regroup with get_foo_display in Django templates

    - by shacker
    I'm using the regroup template tag to group queryset output on a Choices field. In the model: RESOURCE_TYPES = ( ('tut','External tutorial'), ('read','Additional reading'), ('org','Company or organization'), ) restype = models.CharField('Resource type',max_length=6,choices=RESOURCE_TYPES) in the view: resources = Resource.objects.filter(tutorial=tutorial) in the template: {% regroup resources by restype as resource_list %} {% for type in resource_list %} <h3>{{type.grouper}}</h3> So type.grouper renders as 'tut' or 'org' on the page, rather than the long form. Normally you would use the get_foo_display syntax to get at the value of the choice, rather than the key. But the value doesn't seem to be available after going through regroup. There's no way I can find to use get_foo_display on {{type.grouper}}. It makes sense when you think about it, but what's the workaround? Thanks.

  • IIS url rewrite rewriting all .asp to .html

    - by user335711
    I need to create rules for web.config that will rewrite all requests for files with extension .html to .asp and redirect all .asp requests to .html Example: file_xyz.asp rewrites to file_xyz.html directory1/file_xyz.asp rewrites to directory1/file_xyz.html and file_xyz.html redirects to file_xyz.asp directory1/file_xyz.html redirects to directory1/file_xyz.asp What is the syntax for the rule Is this too broad a rule? If I should need for what ever reason to have a physical file such as file_abc.html how do I exclude it from the redirect rule? I am thinking I should just use ISAPI_Rewrite http://www.isapirewrite.com/ there seems to be a ton of resources out there for rewriting with htaccess and very little online help for using IIS 7 URL rewrite. Any thoughts and/or advice Thanks in advance

  • MySQL: Insert row on table2 if row in table1 exists

    - by Andrew M
    I'm trying to set up a MySQL query that will insert a row into table2 if a row in table1 exist already, otherwise it will just insert the row into table1. I need to find a way to adapt the following query into inserting a row into table2 with the existing row's id. INSERT INTO table1 (host, path) VALUES ('youtube.com', '/watch') IF NOT EXISTS ( SELECT * FROM table1 WHERE host='youtube.com' AND path='/watch' LIMIT 1); Something kind of like this: INSERT ... IF NOT EXISTS(..) ELSE INSERT INTO table2 (table1_id) VALUES(row.id); Except I don't know the syntax for this.

  • Cannot position Google +1 button with CSS?

The div is as follows: <div class="g-plusone"></div> The CSS I'm using is pretty simple: .g-plusone { position: absolute; top:95px; left:715px; } I know for a fact that the div in question is being accessed. What's strange is that other social sharing buttons, such as the FB like below follow the same syntax and are positioned perfectly. .fb-like { position: absolute; top:62px; left:715px; } Any ideas?

  • How does dereferencing of a function pointer happen?

    - by eSKay
    Why and how does dereferencing a function pointer just "do nothing"? This is what I am talking about: #include<stdio.h> void hello() { printf("hello"); } int main(void) { (*****hello)(); } From a comment over here: function pointers dereference just fine, but the resulting function designator will be immediately converted back to a function pointer And from an answer here: Dereferencing (in way you think) a function's pointer means: accessing a CODE memory as it would be a DATA memory. Function pointer isn't suppose to be dereferenced in that way. Instead, it is called. I would use a name "dereference" side by side with "call". It's OK. Anyway: C is designed in such a way that both function name identifier as well as variable holding function's pointer mean the same: address to CODE memory. And it allows to jump to that memory by using call () syntax either on an identifier or variable. How exactly does dereferencing of a function pointer work?

  • How can I serialize the values of checked checkboxes in an iFrame into a hidden form field on clicki

    I have an iFrame like so: <iframe width="100%" frameborder="0" height="470" allowtransparency="true" name="productframe" id="productframe" style="border-bottom:1px solid #eee"></iframe> The iframe contains several line items drawn from a sql server db, and I can check any of the checkboxes I want to perform a task with - in this case delete them. I have a button in the parent document that says "Delete selected", and I'd like to be able to click this button and populate a hidden field in my parent page with the values of the selected checkboxes in the child iframe. My checkboxes look like this: <input id="Checkbox1" type="checkbox" value="47" title="Select this row" name="selectItem"/> I have an instance of jquery on my parent page so I can make use of jquery selectors, I just have no clue as to the syntax needed to do this. Thanks in advance to anyone who can help me on this.
