• memory usage by objects in common lisp

  - by Farzad Bekran

  Is there a way to find out how much memory is used by an instance of a class or basic data types in general? I have a toy webframework in cl that creates and manages web pages with instances of classes that represent the html tags and their properties, and as they are supposed to make an html page, they have children in a slot called children. so I was thinking how much a user's session will cost the server if I take this approach. Thanks.

• jQuery.param() - doesn't serialize javascript Date objects?

  - by ehahn9

  jQuery.param({foo: 1}); // => "foo=1" - SUCCESS! jQuery.param({bar: new Date()}); // => "" - OUCH! There is no problem with encodeURIComponent(new Date()), which is what I would have thought param is calling for each member. Also, explicitly using "traditional" param (e.g. jQuery.param(xxx, true)) DOES serialize the date, but alas, that isn't of much help since my data structure isn't flat. Is this because typeof(Date) == "object" and param tries to descend into it to find scalar values? How might one realistically serialize an object that happens to have Date's in it for $.post() etc.?

• Delete cell content in Libre (Open) Office based on the cell value

  - by take2

  I have a huge csv file (tens of thousands of rows) that I need to filter based on different criteria. After trying to find a proper CSV editor, I decided to use LibreOffice Calc. CSVed is great, but it doesn't support neither UTF-8 nor macros for advanced filtering. So, there are 4 columns, 3 of which contain numbers (with decimal numbers) and 1 of which contains text. I'm trying to find a way to delete rows with a macro code. I can achieve the desired behavior with filters too, but it's annoying to type all of the filtering values over and over again and there doesn't seem to be a way to export the filter and us it repeatedly. These rows should be deleted: The ones that don't contain certain words in textual column (column A). There are a few thousand different words used in that column and I want to keep only the rows that contain one of about 30 words in that column. Additionally, the number is the other columns should be bigger than 3.8 (column B), 4.5 (column C) and smaller than 20 (column C). The row-deletion type is "Shift up". Hopefully I have explained it well. Thanks a lot in advance for your help!

• how to add value to windows installer property table

  - by Felix

  According to MSDN installer sets ROOTDRIVE to the local drive that can be written to having the most free space. In my situation it is a slow USB drive that I use for nightly backup, but I would prefer to use my C drive for the install folder. But somehow I can't figure out how to set this property from command line or through PowerShell. I found that it is possible, but these instructions don't make any sense

• ColdFusion static key/value list?

  - by richardtallent

  I have a database table that is a dictionary of defined terms -- key, value. I want to load the dictionary in the application scope from the database, and keep it there for performance (it doesn't change). I gather this is probably some sort of "struct," but I'm extremely new to ColdFusion (helping out another team). Then, I'd like to do some simple string replacement on some strings being output to the browser, looping through the defined terms and replacing the terms with some HTML to define the terms (a hover or a link, details to be worked out later, not important). Can anyone point me in the right direction of: How to define the stucture (if that is what I need for a key/value pair list) How to query at the application start-up and reuse the list properly The best way to do the string replacement

  Scenario: I have a table1(col1 char(5)); A value in table1 may '001' or '01' or '1'.

• ObjectiveC - Releasing objects added as parameters

  - by NobleK

  Ok, here goes. Being a Java developer I'm still struggling with the memory management in ObjectiveC. I have all the basics covered, but once in a while I encounter a challenge. What I want to do is something which in Java would look like this: MyObject myObject = new MyObject(new MyParameterObject()); The constructor of MyObject class takes a parameter of type MyParameterObject which I initiate on-the-fly. In ObjectiveC I tried to do this using following code: MyObject *myObject = [[MyObject alloc] init:[[MyParameterObject alloc] init]]; However, running the Build and Analyze tool this gives me a "Potential leak of an object" warning for the MyParameter object which indeed occurs when I test it using Instruments. I do understand why this happens since I am taking ownership of the object with the alloc method and not relinquishing it, I just don't know the correct way of doing it. I tried using MyObject *myObject = [[MyObject alloc] init:[[[MyParameterObject alloc] init] autorelease]]; but then the Analyze tool told me that "Object sent -autorelease too many times". I could solve the issue by modifying the init method of MyParameterObject to say return [self autorelease]; in stead of just return self;. Analyze still warnes about a potential leak, but it doesn't actually occur. However I believe that this approach violates the convention for managing memory in ObjectiveC and I really want to do it the right way. Thanx in advance.

• How to verify StructureMap is disposing of objects properly

  - by Kevin Pang

  I'm currently using StructureMap to inject instances of NHibernate ISessions using the following code: ObjectFactory.Initialize(x => { x.ForRequestedType<ISession>() .CacheBy(InstanceScope.PerRequest) .TheDefault.Is.ConstructedBy(y => NHibernateSessionManager.Instance.GetSession()); }); I'm assuming that the CacheBy(InstanceScope.PerRequest) will properly dispose of the ISession it creates, but I'd like to make sure. What's the easiest way to test this?

So if I put in an alert ("Hey"); the code runs 6 times and I get 6 alerts. How can I wait for the entire page to load and then start playing with the DOM. Also, I'm using jQuery. Thanks

• Dynamically create and cast objects at runtime

  - by vaibhav bindroo

  Let's say we have 2 classes A and B public class A{ private int member1; A() { member1 = 10; } public getMember(){ return member1; } } Class B is also on the same lines except that its member variable is named member2 and gets intitialized to say 20 inside the constructor. My Requirement : At runtime , I get a string which contains a className ( could be A or B). I want to dynamically create an object of this class along with invoking the constructor. How can I achieve this . I don't want to use interfaces for common functionality of above classes Morever, later on I set the properties of this raw object using Propery Builder Bean Util class based on a list of columns . Class clazz = Class.forName("className"); Obj obj = clazz.newInstance(); How I can dynamically convert that obj to className object.

Do I need to parse the image and look at each pixel or is there an easier way to do it? I'm using Java3D but it doesn't seem to have any sort of built in support for that...

• javascript filter nested object based on key value

  - by murray3

  I wish to filter a nested javascript object by the value of the "step" key: var data = { "name": "Root", "step": 1, "id": "0.0", "children": [ { "name": "first level child 1", "id": "0.1", "step":2, "children": [ { "name": "second level child 1", "id": "0.1.1", "step": 3, "children": [ { "name": "third level child 1", "id": "0.1.1.1", "step": 4, "children": []}, { "name": "third level child 2", "id": "0.1.1.2", "step": 5, "children": []} ]}, ]} ] }; var subdata = data.children.filter(function (d) { return (d.step <= 2)}); This just returns the unmodified nested object, even if I put value of filter to 1. does .filter work on nested objects or do I need to roll my own function here, advise and correct code appreciated. cjm

• Query for value where a default namespace node exists

  - by Jay

  I have the following XML that is provided to me and I cannot change it: <Parent> <Settings Version="1234" xmlns="urn:schemas-stuff-com"/> </Parent> I am trying to retrieve the "Version" attribute value using XPath. It appears since the xmlns is defined without an alias it automatically assigns that xmlns to the Settings node. When I read this XML into an XMLDocument and view the namespaceURI value for the Settings node it is set to "urn:schemas-stuff-com". I have tried: //Parent/Settings/@Version - returns Null //Parent/urn:schemas-stuff-com:Settings/@Version - invalid syntax

• Injecting correct object graph using StructureMap in Queue of different Objects

  - by davy

  I have a queuing service that has to inject a different dependency graph depending on the type of object in the queue. I'm using Structure Map. So, if the object in the queue is TypeA the concrete classes for TypeA are used and if it's TypeB, the concrete classes for TypeB are used. I'd like to avoid code in the queue like: if (typeA) { // setup TypeA graph } else if (typeB) { // setup TypeB graph } Within the graph, I also have a generic classes such as an IReader(ISomething, ISpomethingElse) where IReader is generic but needs to inject the correct ISomething and ISomethingElse for the type. ISomething will also have dependencies and so on. Currently I create a TypeA or TypeB object and inject a generic Processor class using StructureMap into it and then pass a factory manually inject a TypeA or TypeB factory into a method like: Processor.Process(new TypeAFactory) // perhaps I should have an abstract factory... However, because the factory then creates the generic IReader mentioned above, I end up manually injecting all the TypeA or TypeB classes fro there on. I hope enough of this makes sense. I am new to StructureMap and was hoping somebody could point me in the right direction here for a flexible and elegant solution. Thanks
