• Is there a performance advantage in using a 64bit version of openCV+Emgu instead of 32bit?

  - by Jelly Amma

  Hello, I am developing an application that processes images captured in real time by a Point Grey camera (http://www.ptgrey.com/). The Point Grey SDK is a .net wrapper and can be either 32bit or 64bit. Then to process the captured images, I'm using a wrapper for openCV called Emgu CV (http://www.emgu.com/) that comes in both 32bit or 64bit flavors as well. Now, being on Vista64 I went for the 64bit versions of FlyCapture (Point Grey's SDK) and Emgu CV (which includes openCV in its install) hoping to maximize performance. Recently I've been wanting to call my FlyCapture+Emgu DLL code from XNA, which unfortunately only exists in 32bit, and I realize that I may have to reinstall all those components in 32bit as I don't really want to go through IPC, remoting, etc. Apart from the obvious limit to memory space inherent to 32bit, is there also a performance loss I should be expecting? How dramatic would that be and why ? Thanks in advance for any advice or explanation.

• Java: If vs. Switch

  - by _ande_turner_

  I have a piece of code with a) which I replaced with b) purely for legibility ... a) if ( WORD[ INDEX ] == 'A' ) branch = BRANCH.A; /* B through to Y */ if ( WORD[ INDEX ] == 'Z' ) branch = BRANCH.Z; b) switch ( WORD[ INDEX ] ) { case 'A' : branch = BRANCH.A; break; /* B through to Y */ case 'Z' : branch = BRANCH.Z; break; } ... will the switch version cascade through all the permutations or jump to a case ? EDIT: Some of the answers below regard alternative approaches to the approach above. I have included the following to provide context for its use. The reason I asked, the Question above, was because the speed of adding words empirically improved. This isn't production code by any means, and was hacked together quickly as a PoC. The following seems to be a confirmation of failure for a thought experiment. I may need a much bigger corpus of words than the one I am currently using though. The failure arises from the fact I did not account for the null references still requiring memory. ( doh ! ) public class Dictionary { private static Dictionary ROOT; private boolean terminus; private Dictionary A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q, R, S, T, U, V, W, X, Y, Z; private static Dictionary instantiate( final Dictionary DICTIONARY ) { return ( DICTIONARY == null ) ? new Dictionary() : DICTIONARY; } private Dictionary() { this.terminus = false; this.A = this.B = this.C = this.D = this.E = this.F = this.G = this.H = this.I = this.J = this.K = this.L = this.M = this.N = this.O = this.P = this.Q = this.R = this.S = this.T = this.U = this.V = this.W = this.X = this.Y = this.Z = null; } public static void add( final String...STRINGS ) { Dictionary.ROOT = Dictionary.instantiate( Dictionary.ROOT ); for ( final String STRING : STRINGS ) Dictionary.add( STRING.toUpperCase().toCharArray(), Dictionary.ROOT , 0, STRING.length() - 1 ); } private static void add( final char[] WORD, final Dictionary BRANCH, final int INDEX, final int INDEX_LIMIT ) { Dictionary branch = null; switch ( WORD[ INDEX ] ) { case 'A' : branch = BRANCH.A = Dictionary.instantiate( BRANCH.A ); break; case 'B' : branch = BRANCH.B = Dictionary.instantiate( BRANCH.B ); break; case 'C' : branch = BRANCH.C = Dictionary.instantiate( BRANCH.C ); break; case 'D' : branch = BRANCH.D = Dictionary.instantiate( BRANCH.D ); break; case 'E' : branch = BRANCH.E = Dictionary.instantiate( BRANCH.E ); break; case 'F' : branch = BRANCH.F = Dictionary.instantiate( BRANCH.F ); break; case 'G' : branch = BRANCH.G = Dictionary.instantiate( BRANCH.G ); break; case 'H' : branch = BRANCH.H = Dictionary.instantiate( BRANCH.H ); break; case 'I' : branch = BRANCH.I = Dictionary.instantiate( BRANCH.I ); break; case 'J' : branch = BRANCH.J = Dictionary.instantiate( BRANCH.J ); break; case 'K' : branch = BRANCH.K = Dictionary.instantiate( BRANCH.K ); break; case 'L' : branch = BRANCH.L = Dictionary.instantiate( BRANCH.L ); break; case 'M' : branch = BRANCH.M = Dictionary.instantiate( BRANCH.M ); break; case 'N' : branch = BRANCH.N = Dictionary.instantiate( BRANCH.N ); break; case 'O' : branch = BRANCH.O = Dictionary.instantiate( BRANCH.O ); break; case 'P' : branch = BRANCH.P = Dictionary.instantiate( BRANCH.P ); break; case 'Q' : branch = BRANCH.Q = Dictionary.instantiate( BRANCH.Q ); break; case 'R' : branch = BRANCH.R = Dictionary.instantiate( BRANCH.R ); break; case 'S' : branch = BRANCH.S = Dictionary.instantiate( BRANCH.S ); break; case 'T' : branch = BRANCH.T = Dictionary.instantiate( BRANCH.T ); break; case 'U' : branch = BRANCH.U = Dictionary.instantiate( BRANCH.U ); break; case 'V' : branch = BRANCH.V = Dictionary.instantiate( BRANCH.V ); break; case 'W' : branch = BRANCH.W = Dictionary.instantiate( BRANCH.W ); break; case 'X' : branch = BRANCH.X = Dictionary.instantiate( BRANCH.X ); break; case 'Y' : branch = BRANCH.Y = Dictionary.instantiate( BRANCH.Y ); break; case 'Z' : branch = BRANCH.Z = Dictionary.instantiate( BRANCH.Z ); break; } if ( INDEX == INDEX_LIMIT ) branch.terminus = true; else Dictionary.add( WORD, branch, INDEX + 1, INDEX_LIMIT ); } public static boolean is( final String STRING ) { Dictionary.ROOT = Dictionary.instantiate( Dictionary.ROOT ); return Dictionary.is( STRING.toUpperCase().toCharArray(), Dictionary.ROOT, 0, STRING.length() - 1 ); } private static boolean is( final char[] WORD, final Dictionary BRANCH, final int INDEX, final int INDEX_LIMIT ) { Dictionary branch = null; switch ( WORD[ INDEX ] ) { case 'A' : branch = BRANCH.A; break; case 'B' : branch = BRANCH.B; break; case 'C' : branch = BRANCH.C; break; case 'D' : branch = BRANCH.D; break; case 'E' : branch = BRANCH.E; break; case 'F' : branch = BRANCH.F; break; case 'G' : branch = BRANCH.G; break; case 'H' : branch = BRANCH.H; break; case 'I' : branch = BRANCH.I; break; case 'J' : branch = BRANCH.J; break; case 'K' : branch = BRANCH.K; break; case 'L' : branch = BRANCH.L; break; case 'M' : branch = BRANCH.M; break; case 'N' : branch = BRANCH.N; break; case 'O' : branch = BRANCH.O; break; case 'P' : branch = BRANCH.P; break; case 'Q' : branch = BRANCH.Q; break; case 'R' : branch = BRANCH.R; break; case 'S' : branch = BRANCH.S; break; case 'T' : branch = BRANCH.T; break; case 'U' : branch = BRANCH.U; break; case 'V' : branch = BRANCH.V; break; case 'W' : branch = BRANCH.W; break; case 'X' : branch = BRANCH.X; break; case 'Y' : branch = BRANCH.Y; break; case 'Z' : branch = BRANCH.Z; break; } if ( branch == null ) return false; if ( INDEX == INDEX_LIMIT ) return branch.terminus; else return Dictionary.is( WORD, branch, INDEX + 1, INDEX_LIMIT ); } }

• String.Empty in strings, need some explanation if possible :)

  - by Pabuc

  Hello all, 2 days ago, there was a question related to string.LastIndexOf(String.Empty) returning the last index of string. So I thought that; a string can always contain string.empty between characters like: "testing" == "t" + String.Empty + "e" + String.Empty +"sting" + String.Empty; After this, I wanted to test if String.IndexOf(String.Empty) was returning 0 because since String.Empty can be between any char in a string, that would be what I expect it to return and I wasn't wrong. string testString = "testing"; int index = testString.LastIndexOf(string.Empty); // index is 6 index = testString.IndexOf(string.Empty); // index is 0 It actually returned 0. I started to think that if I could split a string with String.Empty, I would get at least 2 string and those would be String.Empty and rest of the string since String.IndexOf(String.Empty) returned 0 and String.LastIndexOf(String.Empty) returned length of the string.. Here is what I coded: string emptyString = string.Empty; char[] emptyStringCharArr = emptyString.ToCharArray(); string myDummyString = "abcdefg"; string[] result = myDummyString.Split(emptyStringCharArr); The problem here is, I can't obviously convert String.Empty to char[] and result in an empty string[]. I would really love to see the result of this operation and the reason behind this. So my questions are: Is there any way to split a string with String.Empty? If it is not possible but in an absolute world which it would be possible, would it return an array full of chars like [0] = "t" [1] = "e" [2] = "s" and so on or would it just return the complete string? Which would make more sense and why? Thank you for your time.

• PHP text formating: Detecting several symbols in a row

  - by ilnur777

  I have a kind of strange thing that I really nead for my text formating. Don't ask me please why I did this strange thing! ;-) So, my PHP script replaces all line foldings "\n" with one of the speacial symbol like "|". When I insert text data to database, the PHP script replaces all line foldings with the symbol "|" and when the script reads text data from the database, it replaces all special symbols "|" with line folding "\n". I want to restrict text format in the way that it will cut line foldings if there are more than 2 line foldings used in each separating texts. Here is the example of the text I want the script to format: this is text... this is text... this is text...this is text...this is text... this is text... this is text... this is text... this is text... this is text... this is text... this is text... this is text... this is text... this is text... this is text... this is text... this is text... this is text... this is text... I want to restict format like: this is text... this is text... this is text...this is text...this is text... this is text... this is text... this is text... this is text... this is text... this is text... this is text... this is text... this is text... this is text... this is text... this is text... this is text... this is text... this is text... So, at the first example there is only one line folding between 2 texts and on the second example there are 3 line foldings between 2 texts. How it can be possible to replace more than 2 line foldings symbols "|" if they are detected on the text? This is a kind of example I want the script to do: $text = str_replace("|||", "||", $text); $text = str_replace("||||", "||", $text); $text = str_replace("|||||", "||", $text); $text = str_replace("||||||", "||", $text); $text = str_replace("|||||||", "||", $text); ... $text = str_replace("||||||||||", "||", $text); $text = str_replace("|", "<br>", $text); HM, I HAVE PROBLEMS! THIS DOES NOT WORK WHEN TEXT DATA IS SENT IN POST METHOD. LOOK AT THIS: //REPLACING ALL LINE FOLDINGS WITH SPECIAL SYMBOL $_POST["text"] = str_replace("\n","|",$_POST["text"]); // REMOVING ALL LINE FOLDINGS $_POST["text"] = trim($_POST["text"]); // IF THERE ARE MORE THAN 3 LINE HOLDINGS - FORMAT TO 1 LINE HOLDING $_POST["text"] = preg_replace("/\|{3,}/", "||", $_POST["text"]); echo $_POST["text"];

I've put Environment.NewLine to create a line break but have no success till now. So I think I need to RowCreated or RowDataBound, etc. events to make modifications.

• finding a string of random characters (with possible errors) within a large string of random charact

  - by mike

  I am trying to search a large string w/o spaces for a smaller string of characters. using regex I can easily find perfect matches but I can't figure out how to find partial matches. by partial matches i mean one or two extra characters in the string or one or two characters that have been changed, or one of each. the first and last characters will always match though. this would be similar to a spell checker but there are no spaces and the strings dont contain actual words, just random hex digits. i figured a way to find the string if there are no extra characters using indexOf(string.charAt(0)) and indexOf(charAt(string.length()-1) and looping through the characters between the two indexes. but this can be problematic when dealing with randomized characters because of the possibility of finding the first and last characters at the correct spacing but none of the middle characters matching. i've been scratching my head for hours on this issue. any ideas?

• Best way to compare contents of two tables in Teradata?

  - by Cade Roux

  When you need to compare two tables to see what the differences are, are there any tools or shortcuts you use, or do you handcode the SQL to compare the two tables? Background: In my SQL Server environment, I created a stored procedure which inspects the metadata of the two tables/views, creates a query (as dynamic sql) which joins the two tables on the specified key columns, and compares data in the compare columns, reporting key differences and data differences. The query can either be printed and modified/copied or just excecuted as is. We are not allowed to create stored procedures in our Teradata environment, unfortunately.

• Weird result comparing property values using reflection

  - by Brian

  Can someone explain why this is occurring? The code below was executed in the immediate window in vs2008. The prop is an Int32 property (id column) on an object created by the entity framework. The objects entity and defaultEntity were created using Activator.CreateInstance(); Convert.ChangeType(prop.GetValue(entity, null), prop.PropertyType) 0 Convert.ChangeType(prop.GetValue(defaultEntity, null), prop.PropertyType) 0 Convert.ChangeType(prop.GetValue(entity, null), prop.PropertyType) == Convert.ChangeType(prop.GetValue(defaultEntity, null), prop.PropertyType) false

• Use Maven to trigger a wsgen & wsimport in a row, using wsdlLocation

  - by ben

  I have hard times using maven to generate my client. So Please refer to http://stackoverflow.com/questions/2131001/creating-a-web-service-client-directly-from-the-source for the first part of my question. To keep it simple and short, I want to go from here (a file in src/main/java) : package com.example.maven.jaxws.helloservice; import javax.jws.WebService; @WebService public class Hello { public String sayHello(String param) { ; return "Hello " + param; } } to there : /** * This class was generated by the JAX-WS RI. * JAX-WS RI 2.1.7-b01- * Generated source version: 2.1 * */ @WebServiceClient(name = "HelloService", targetNamespace = "http://helloservice.jaxws.maven.example.com/", wsdlLocation = "http://localhost:8080/test/") public class HelloService extends Service { private final static URL HELLOSERVICE_WSDL_LOCATION; private final static Logger logger = Logger.getLogger(com.example.wsimport.HelloService.class.getName()); ...etc using only 1 pom.xml file. Please note the wsdlLocation set on the end. The pom.xml file will probably use both maven-jaxws-plugin wsgen AND wsimport with some tricky configuration to achieve this.

• Fuzzy Regular Expressions

  - by Thomas Ahle

  In my work I have with great results used approximate string matching algorithms such as Damerau–Levenshtein distance to make my code less vulnerable to spelling mistakes. Now I have a need to match strings against simple regular expressions such TV Schedule for \d\d (Jan|Feb|Mar|...). This means that the string TV Schedule for 10 Jan should return 0 while T Schedule for 10. Jan should return 2. This could be done by generating all strings in the regex (in this case 100x12) and find the best match, but that doesn't seam practical. Do you have any ideas how to do this effectively?

• compare two windows paths, one containing tilde, in python

  - by Steve Cooper

  I'm trying to use the TMP environment variable in a program. When I ask for tmp = os.path.expandvars("$TMP") I get C:\Users\STEVE~1.COO\AppData\Local\Temp Which contains the old-school, tilde form. A function I have no control over returns paths like C:\Users\steve.cooper\AppData\Local\Temp\file.txt My problem is this; I'd like to check if the file is in my temp drive, but I can't find a way to compare them. How do you tell if these two Windows directories; C:\Users\STEVE~1.COO\AppData\Local\Temp C:\Users\steve.cooper\AppData\Local\Temp are the same?

• SQL select descendants of a row

  - by Joey Adams

  Suppose a tree structure is implemented in SQL like this: CREATE TABLE nodes ( id INTEGER PRIMARY KEY, parent INTEGER -- references nodes(id) ); Although cycles can be created in this representation, let's assume we never let that happen. The table will only store a collection of roots (records where parent is null) and their descendants. The goal is to, given an id of a node on the table, find all nodes that are descendants of it. A is a descendant of B if either A's parent is B or A's parent is a descendant of B. Note the recursive definition. Here is some sample data: INSERT INTO nodes VALUES (1, NULL); INSERT INTO nodes VALUES (2, 1); INSERT INTO nodes VALUES (3, 2); INSERT INTO nodes VALUES (4, 3); INSERT INTO nodes VALUES (5, 3); INSERT INTO nodes VALUES (6, 2); which represents: 1 `-- 2 |-- 3 | |-- 4 | `-- 5 | `-- 6 We can select the (immediate) children of 1 by doing this: SELECT a.* FROM nodes AS a WHERE parent=1; We can select the children and grandchildren of 1 by doing this: SELECT a.* FROM nodes AS a WHERE parent=1 UNION ALL SELECT b.* FROM nodes AS a, nodes AS b WHERE a.parent=1 AND b.parent=a.id; We can select the children, grandchildren, and great grandchildren of 1 by doing this: SELECT a.* FROM nodes AS a WHERE parent=1 UNION ALL SELECT b.* FROM nodes AS a, nodes AS b WHERE a.parent=1 AND b.parent=a.id UNION ALL SELECT c.* FROM nodes AS a, nodes AS b, nodes AS c WHERE a.parent=1 AND b.parent=a.id AND c.parent=b.id; How can a query be constructed that gets all descendants of node 1 rather than those at a finite depth? It seems like I would need to create a recursive query or something. I'd like to know if such a query would be possible using SQLite. However, if this type of query requires features not available in SQLite, I'm curious to know if it can be done in other SQL databases.
