  • Notification of low DHCP pool in split scope setup

    - by JJBladester
    In Windows Server 2008 R2, it is possible to read the Event Viewer for EventID 1020 which is an indication that the DHCP pool is running low on addresses. What if I have two DHCP servers in my domain that use an 80/20 split scope to take a /24 pool of DHCP-allocated IP addresses and split it amongst the two servers according to this Technet Article? In this case, since the scope is split, how can I tell if the total DHCP pool, which is split amongst the two DHCP servers, is beginning to run low on address space?

  • onload Event in embedded SVG not calling function in attached script. Scope Issue?

    - by Nick
    Hi So I've got an XHTML page with a script - not inline > <script type="text/javascript" > src="../global/js/scripts.js"></script> and an embedded (I tried embed and object, same behavior) SVG document with a onload="CheckIfLoaded(evt)" attribute. The problem is firefox doesn't call the CheckIfLoaded() function in scripts.js. Firebug gives me "CheckIfLoaded() is not defined" with no reference to any line numbers. I can't find any information regarding the scope of javascript functions with respect to embedded content. Curiously, it works fine in IE. I could of course add a reference to the script into the SVG file as well but I believe that will result in the client downloading the scripts file twice and in addition I have 1000+ svg files and I'd really rather not add one line to all of them, although I suppose I could write a batch file or whatever if I have to. Any one know more about this? Thanks, Nick

  • If the "with" statement in Javascript creates a new scope, why does the following code not work as e

    - by Jian Lin
    If the "with" statement in Javascript creates a new scope, shouldn't clicking on the links show a different x which are in different scopes? It doesn't. <a href="#" id="link1">ha link 1</a> <a href="#" id="link2">ha link 2</a> <a href="#" id="link3">ha link 3</a> <a href="#" id="link4">ha link 4</a> <a href="#" id="link5">ha link 5</a> <script type="text/javascript"> for (i = 1; i <= 5; i++) { with({foo:"bar"}) { var x = i; document.getElementById('link' + i).onclick = function() { alert(x); return false; } } } </script>

  • Possible typos in ECMAScript 5 specification?

    - by Andy West
    Does anybody know why, at the end of section 7.6 of the ECMA-262, 5th Edition specification, the nonterminals UnicodeLetter, UnicodeCombiningMark, UnicodeDigit, UnicodeconnectorPunctuation, and UnicodeEscapeSequence are not followed by two colons? From section 5.1.6: Nonterminal symbols are shown in italic type. The definition of a nonterminal is introduced by the name of the nonterminal being defined followed by one or more colons. (The number of colons indicates to which grammar the production belongs.) Since lexical productions are distinguished by having two colons, and this is under "Lexical Conventions", I'm assuming that they meant to put the colons in. Does that sound right? Just making sure that these really are nonterminals and they really are part of the lexical grammar. EDIT: I noticed there have been votes to close this. Just to make my case about why this is programming-related, it is relevant to anyone wanting to implement an ECMAScript interpreter.

  • What's the scope of a Javascript variable declared in a for() loop?

    - by Dylan Beattie
    Check out the following snippet of HTML/Javascript code: <html> <head> <script type="text/javascript"> var alerts = []; for(var i = 0; i < 3; i++) { alerts.push(function() { document.write(i + ', '); }); } for (var j = 0; j < 3; j++) { (alerts[j])(); } for (var i = 0; i < 3; i++) { (alerts[i])(); } </script> </head><body></body></html> This outputs: 3, 3, 3, 0, 1, 2 which isn't what I was expecting - I was expecting the output 0, 1, 2, 0, 1, 2, I (incorrectly) assumed that the anonymous function being pushed into the array would behave as a closure, capturing the value of i that's assigned when the function is created - but it actually appears that i is behaving as a global variable. Can anyone explain what's happening to the scope of i in this code example, and why the anonymous function isn't capturing its value?

  • What's the best way to resolve this scope problem?

    - by Peter Stewart
    I'm writing a program in python that uses genetic techniques to optimize expressions. Constructing and evaluating the expression tree is the time consumer as it can happen billions of times per run. So I thought I'd learn enough c++ to write it and then incorporate it in python using cython or ctypes. I've done some searching on stackoverflow and learned a lot. This code compiles, but leaves the pointers dangling. I tried 'this_node = new Node(...' . It didn't seem to work. And I'm not at all sure how I'd delete all the references as there would be hundreds. I'd like to use variables that stay in scope, but maybe that's not the c++ way. What is the c++ way? class Node { public: char *cargo; int depth; Node *left; Node *right; } Node make_tree(int depth) { depth--; if(depth <= 0) { Node tthis_node("value",depth,NULL,NULL); return tthis_node; } else { Node this_node("operator" depth, &make_tree(depth), &make_tree(depth)); return this_node; } };

  • Fuzzy Regex, Text Processing, Lexical Analysis?

    - by justinzane
    I'm not quite sure what terminology to search for, so my title is funky... Here is the workflow I've got: Semi-structured documents are scanned to file. The files are OCR'd to text. The text is parsed into Python objects The objects are serialized (to SQL, JSON, whatever) for use. The documents are structures like this: HEADER blah blah, Page ### blah Garbage text... 1. Question Text... continued until now. A. Choice text... adsadsf. B. Another Choice... 2. Another Question... I need to extract the questions and choices. The problem is that, because the text is OCR output, there are occasional strange substitutions like '2' - 'Z' which makes ordinary regular expressions useless. I've tried the Levenshtein module and it helps, but it requires prior knowledge of what edit distance is to be expected. I don't know whether I'm looking to create a parser? a lexer? something else? This has lead me down all kinds of interesting but nonrelevant paths. Guidance would be greatly appreciated. Oh, also, the text is generally from specific technical domains, so general spelling tools are not so helpful. Regarding the structure of the documents, there is no clear visual pattern -- like line breaks or indentation -- with the exception of the fact that "questions" usually begin a line. Crap on the document can cause characters to appear before the actual beginning of the line, which means that something along the lines of r'^[0-9]+' does not reliably work. Though the "questions" always begin with an int, a period and a space; the OCR can substitute other characters or skip characters. This is not so much a problem with Tesseract or Cunieform, rather with the poor quality of the paper documents. # Note: for the project in question, it was decided that having a human prep the OCR'd text was better that spending the time coding a solution. I'd still love good pointers, however.

  • Rails, if instance is in a scope?

    I using rails 3 and I can't seem to check if a given instance is in a scope, see here: p = Post.find 6 +----+----------+-------------------------+-------------------------+-------------------------+-----------+ | id | title | publish_date | created_at | updated_at | published | +----+----------+-------------------------+-------------------------+-------------------------+-----------+ | 6 | asfdfdsa | 2010-03-28 22:33:00 UTC | 2010-03-28 22:33:46 UTC | 2010-03-28 22:33:46 UTC | true | +----+----------+-------------------------+-------------------------+-------------------------+-----------+ I have a menu scope which looks like: scope :menu, where("published != ?", false).limit(4) When I run it I get: Post.menu.all +----+------------------+------------------+------------------+-------------------+-----------+ | id | title | publish_date | created_at | updated_at | published | +----+------------------+------------------+------------------+-------------------+-----------+ | 1 | Lorem ipsum | 2010-03-23 07... | 2010-03-23 07... | 2010-03-28 21:... | true | | 2 | fdasf | 2010-03-28 21... | 2010-03-28 21... | 2010-03-28 21:... | true | | 3 | Ruby’s Imple... | 2010-03-28 21... | 2010-03-28 21... | 2010-03-28 21:... | true | | 4 | dsaD | 2010-03-28 22... | 2010-03-28 22... | 2010-03-28 22:... | true | +----+------------------+------------------+------------------+-------------------+-----------+ Which is correct, but if I try to check if p is in the the menu scope using: Post.menu.exists?(p) I get true when it should be false What is the proper way to find out if a given instance of something is in a scope?

  • NSDate out of scope

    - by therealtkd
    Having problems with out of scope for NSDate in an iphone app. I have an interface defined like this: @interface MyObject : NSoObject { NSMutableArray *array; BOOL checkThis; NSDate *nextDue; } Now in the implementation I have this: -(id) init { if( (self=[super init]) ) { checkThis = NO; array = [[NSMutableArray alloc] init]; nextDue = [[NSDate date] retain]; NSDate *testDate = [NSDate date]; } return self; } Now, if I trace through the init, before I actually assign the variables checkThis shows as boolean. array shows as pointer 0x0 because it hasn't ben assigned. But the nextDue is showing as 'out of scope'. I don't understand why this is out of scope but the other variables aren't. If I trace through the code until after the variables are assigned, array now shows as being correctly assigned but nextDue is still out of scope. Interestingly, the testDate variable is assigned just fine and the debugger shows this as a valid date. Further interesting point is if I move the mouse over the testDate variable while I am debugging, it shows as an 'NSDate *' type which I would expect since that's its definition. Yet the nextDue, which to me is defined the same way is showing as a '_NSCFDate *'. Any googling I did on the subject said that the retain is the problem, but its actually out of scope before I even try to assign the variable. However, in another class, the same definition for NSDate work ok. It shows as nil before a value is assigned to it. Arghhh

  • lexical analysis gives only one output?

    - by Caffè
    I tested this example(lexe.java), but it gave me only one output. I gave this text as a reader: public class LexeTest{ private int a = 14; } And the nextToken() function is : public Category nextToken () { if (inp.findWithinHorizon (tokenPat, 0) == null) return Category.EOF; else { lastLexeme = inp.match ().group (0); if (inp.match ().start (1) != -1) return nextToken (); else if (inp.match ().start (2) != -1) return Category.IDENT; else if (inp.match ().start (3) != -1) return Category.NUMERAL; Category result = tokenMap.get (lastLexeme); if (result == null) return Category.ERROR; else return result; } } Isdie the main method: System.out.println(lexeObject.nextToken()); output is : IDENT Why? but the textfile contains multiple keywords? Anyone know what's the problem?

  • Understanding DHCP setting for DNS Server Options and Scope Options

    - by Saariko
    I have installed 2 DC's on my network (W2K8 R2) both serve as a replicate DC on my domain. On one of them (DC1) there is also a DHCP server running. On both I have a DNS server running. I am trying to understand the difference in the settings within the DHCP of Server Options and Scope Options. As I understand it: On the server options, I should put an external DNS for system (lets say 8.8.8.8 - google) And on the scope options, I should put both my internal dc1 and dc2 IP's as the server. - which are than distributed to my domain clients. Is that correct? Is there a better way? Do I need to add loopback address as well?

  • How can I access variables outside of current scope in javascript?

    - by sekmet64
    I'm writing some application in javascript and cannot figure it out how to access the variables declared in my function, inside this jquery parse. Inside I can access global variables, but I don't really want to create global vars for these values. Basically I want to extract file names from an xml document in the simulationFiles variable. I check if the node attribute is equal with the simName and extract the two strings inside the xml elements, that part I think it's working. How can I extract those xml elements and append them to local variables? function CsvReader(simName) { this.initFileName = "somepath"; this.eventsFileName = "somepath"; $(simulationFiles).find('simulation').each(function() { if ($(this).attr("name") == simName) { initFileName += $(this).find("init").text(); eventsFileName += $(this).find("events").text(); } }); }

  • My Oracle 9i package won't compile, says that a user-defined function is out of scope... but it isn'

    - by bitstream
    I have an Oracle package which contains user-defined functions and procedures, including two user-defined functions which are called from SELECT and UPDATE statements. The functions in question are defined before the procedures that call them. This piece of code compiles and works fine on Oracle 10g but won't compile on 9i. The code should work as-is according to Oracle's own documentation. Any idea why it would throw this error on 9i?

  • Pass page scope attributes to a JSP using pagecontext.include for use in JSTL?

    - by hal10001
    We're using this JSP template solution almost verbatim at work: http://java.sun.com/developer/technicalArticles/javaserverpages/jsp_templates/ When it gets JSP pages to be included, it uses pageContext.include, which leaves us with one problem, and that is that we have a lot of scriplet code that gets initialized in the JSP itself (tag soup). My thought was to modify the template tag with an additional attribute that is a package path reference to a class with an init or execute method. That execute would get called first, and would add page context attributes before including the JSP. We would then use JSTL to access those attributes. However, I was told this wouldn't work because of how pageContext.include works, and the inability to pass through attributes scoped to the page. Is that true, and are there workarounds? I'm so-so on knowing all my scoping rules.

  • What's the scope of a Python variable declared in an if statement?

    - by froadie
    I'm new to Python, so this is probably a simple scoping question. The following code in a Python file (module) is confusing me slightly: if __name__ == '__main__': x = 1 print x In other languages I've worked in, this code would throw an exception, as the x variable is local to the if statement and should not exist outside of it. But this code executes, and prints 1. Can anyone explain this behavior? Are all variables declared in a module global/available to the entire module?

  • How do I resolve this scope issue in VB .NET?

    - by froadie
    I have a code structure something like this: For row = 1 To numRows Dim arrayIndex As Integer = 0 For column As Integer = bucketStartColumn To bucketEndColumn ' whatever code arrayIndex = arrayIndex + 1 Next Next Dim arrayIndex As Integer = 0 For column As Integer = bucketStartColumn To bucketEndColumn ' whatever code arrayIndex = arrayIndex + 1 Next Not exactly the code, so I don't really need suggestions about refactoring, but my problem is this - with this code I get a compiler error for the first Dim arrayIndex As Integer = 0 - "Variable 'arrayIndex' hides a variable in an enclosing block." As far as I can tell, arrayIndex is local to the first for loop and shouldn't exist by the time we reach the second loop. If I try to change the second declaration of arrayIndex to arrayIndex = 0, I get the error "Name 'arrayIndex' is not declared", as I expected. So is it visible, or not? Does this have something to do with the Dim keyword? Any suggestions of how to get around this, other than naming the second index variable something else?

  • will_paginate with named_scopes

    - by Lowgain
    I'm using will_paginate for pagination, which has been working well so far, except for this one thing. If I try to paginate a scope, for instance class User < ActiveRecord::Base named_scope :scope, lambda { etc } end User.scope.paginate({:page => params[:page], :per_page => 10}) That will tell me paginate is an undefined method. I'd rather not have to use a second solution for only this scope, is there something I can do here?

  • Passing arguments to scope_procedure in searchlogic

I can't figure out how to pass parameters to the named scope.

  • RSpec and stubbing parameters for a named scope

    - by Andy Waite
    I'm try to write a spec for a named scope which is date dependent. The spec: it "should return 6 months of documents" do Date.stub!(:today).and_return(Date.new(2005, 03, 03)) doc_1 = Factory.create(:document, :date => '2005-01-01') Document.past_six_months.should == [doc_1] end The named scope in the Document model: named_scope :past_six_months, :conditions => ['date > ? AND date < ?', Date.today - 6.months, Date.today] The spec fails with an empty array, and the query in test.log shows why: SELECT * FROM "documents" WHERE (date > '2009-11-11' AND date < '2010-05-11') i.e. it appears to be ignoring my stubbed Date method. However, if I use a class method instead of a named scope then it passes: def self.past_six_months find(:all, :conditions => ['date > ? AND date < ?', Date.today - 6.months, Date.today]) end I would rather use the named scope approach but I don't understand why it isn't working.

  • using pom for test scope dependencies

    - by IttayD
    Hi, Is it possible to create a pom file so it can be used inside another pom to add test scope dependencies? So in module E's pom.xml I have: <dependencies> <dependency> <groupId>com.example</artifactId> <artifactId>D</artifactId> <type>pom</type> <scope>test</scope> </dependency> </dependencies> So that if D's pom.xml contains dependencies on artifacts A, B, C, then these artifacts are in the compilation and execution classpath of E's tests. NOTE: the reason I want such a pom, and not rely on regular dependency resolution is that I have created a tests jar using maven-jar-plugin:test-jar and using that jar as a dependency causes maven to not use its transitive dependencies. (see http://jira.codehaus.org/browse/MNG-1378) UPDATE: this does not work for me (maybe because I'm trying to use it for the test scope): http://www.sonatype.com/books/mvnref-book/reference/pom-relationships-sect-pom-best-practice.html
