• Image Processing, joining the small images to form the main image

  - by n0idea

  Good morning everyone, Actually I'm having a small issue in image processing and I'm in need of some help. First of all, let me explain what i want to do, i have an image that was split into 4 other small images. I currently have like 6 small images that i need to figure out which ones are part of the real image. Second, what i currently know is that that i should compare these images edges or last column with the first column of the other image. I'm not sure yet what exactly should be done, anyone is able to put me on the same tracks, with some detailed hints and how to compare the edges of 2 images. Some links and example codes will be help full. One more thing, how am i able to read .Raw images using java, c# or python ?

• Is Cancan's accessible_by my best choice for altering admin scope on the fly?

  - by evanchurchill

  Situation: On my site, I have a comment model, with a deleted field. Users cannot see deleted comments, but I would like to allow admins to see deleted comments, if they choose to. This will be accomplished by having a scope for users with the admin role which allows them to view comments with the deleted field set to false, as well as true. Question: Is Cancan's accessible_by method my best choice for doing so? From what I've read, it sounds like it will facilitate exactly what I'm trying to do, but, I don't want to implement something that is inefficient, if there is a better method.

• WiX, how to prevent files from uninstalling though we forgot to set Permanent="yes"

  - by Doc Brown

  We have a product installer created with Wix, containing a program package ("V1") and some configuration files. Now, we are going to make a major upgrade with a new product code, where the old version of the product is uninstalled and "V2" is installed. What we want is to save one of the configuration files from uninstalling, since it is needed for the V2, too. Unfortunately, we forgot to set the Permanent="yes" option when we delivered V1 (read this question for more information). Here comes the question: is there an easy way of preventing the uninstall of the file anyhow? Of course, we could add a custom action to the script to backup the file before uninstallation, and another custom action to restore it afterwards, but IMHO that seems to be overkill for this task, and might interfere with other parts of the MSI registration process.

• Java: how to name boolean properties

  - by NoozNooz42

  I just had a little surprise in a Webapp, where I'm using EL in .jsp pages. I added a boolean property and scratched my head because I had named a boolean "isDynamic", so I could write this: <c:if test="${page.isDynamic}"> ... </c:if> Which I find easier to read than: <c:if test="${page.dynamic}"> ... </c:if> However the .jsp failed to compile, with the error: javax.el.PropertyNotFoundException: Property 'isDynamic' not found on type com... I turns out my IDE (and it took me some time to notice it), when generating the getter, had generated a method called: isDynamic() instead of: getIsDynamic() Once I manually replaced isDynamic() by getIsDynamic() everything was working fine. So I've got really two questions here: is it bad to start a boolean property's name with "is"? wether it is bad or not, didn't IntelliJ made a mistake here by auto-generating a method named isDynamic instead of getIsDynamic?

• Python: Is there a way to get HTML that was dynamically created by Javascript?

  - by Joschua

  As far as I can tell, this is the case for LyricWikia. The lyrics (example) can be accessed from the browser, but can't be found in the source code (can be opened with CTRL + U in most browsers) or reading the contents of the site with Python: from urllib.request import urlopen URL = 'http://lyrics.wikia.com/Billy_Joel:Piano_Man' r = urlopen(URL).read().decode('utf-8') And the test: >>> 'Now John at the bar is a friend of mine' in r False >>> 'John' in r False But when you select and look at the source code of the box in which the lyrics are displayed, you can see that there is: <div class="lyricbox">[...]</div> Is there a way to get the contents of that div-element with Python?

• Unit testing a SQL code generator

  - by Tom H.

  The team I'm on is currently writing code in TSQL to generate TSQL code that will be saved as scripts and later run. We're having a little difficulty in separating our unit tests between testing the code generator parts and testing the actual code that they generate. I've read through another similar question, but I was hoping to get some specific examples of what kind of unit test cases we might have. As an example, let's say that I have a bit of code that simply generates a DROP statement for a view, given the view schema and name. Do I just test that the generated code matches some expected outcome using string comparisons and then in a later integration or system test make sure that the drop actually drops the view if it exists, does nothing if the view doesn't exist, or raises an error if the view is one that we are marking as not allowing a drop? Thanks for any advice!

• Buffer management for socket application best practice

  - by Poni

  Having a Windows IOCP app............ I understand that for async i/o operation (on network) the buffer must remain valid for the duration of the send/read operation. So for each connection I have one buffer for the reading. For sending I use buffers to which I copy the data to be sent. When the sending operation completes I release the buffer so it can be reused. So far it's nice and not of a big issue. What remains unclear is how do you guys do this? Another thing is that even when having things this way, I mean multi-buffers, the receiver side might be flooded (talking from experience) with data. Even setting SO_RCVBUF to 25MB didn't help in my testings. So what should I do? Have a to-be-sent queue?

• End User Ad-Hoc Reporting Tool: Microsoft SQL Server Management Studio or Microsoft Access?

  - by schultkl

  Our centralized IT department has suggested two primary ad hoc query tools for our general user base of approximately 200 staff members: Microsoft SQL Server Management Studio 2008 (SSMS) Microsoft Access 2003 Environment The backend database is a read-only Microsoft SQL Server 2005 database. The schema is 400+ tables; allowing access to the raw data for our general staff would be a disaster. We will be building an "abstraction layer" over the raw data for our general staff to run ad hoc queries against. The abstraction layer will most likely contain a number of views. A number of users have basic knowledge in Microsoft Access; none have used SSMS. Which of the above tools (or alternative) would be best for a decidedly non-techie user base of approximately 200 people? What are the pros and cons of each? Also, the IT department has suggested teaching people T-SQL so they may use SSMS. Is this reasonable?

• Type patterns and generic classes in Haskell

  - by finnsson

  I'm trying to understand type patterns and generic classes in Haskell but can't seem to get it. Could someone explain it in laymen's terms? In [1] I've read that "To apply functions generically to all data types, we view data types in a uniform manner: except for basic predefined types such as Float, IO, and ?, every Haskell data type can be viewed as a labeled sum of possibly labeled products." and then Unit, :*: and :+: are mentioned. Are all data types in Haskell automatically versions of the above mentioned and if so how do I figure out how a specific data type is represented in terms of :*:, etc? The users guide for generic classes (ch. 7.16) at haskell.org doesn't mention the predefined types but shouldn't they be handled in every function if the type patterns should be exhaustive?

• What are some C++ Standard Library usage best practices?

  - by apphacker

  I'm learning C++ and the book I'm reading (The C++ Programming Language) says to not reinvent the wheel, to rely on the standard libraries. In C, I often end up creating a linked list, and link list iteration over and over again (maybe I'm doing that wrong not sure), so the ideas of containers available in C++, and strings, and algorithms really appeal to me. However I have read a little online, and heard some criticisms from my friends and coworkers about STL, so I thought I maybe I'd pick some brains here. What are some best practices for using STL, and what lessons have you learned about STL?

• Praat scripting

  - by Binaryrespawn

  Hi all, I am trying to write a praat script to do preprocessing on hundreds of speach samples. I need to extract speech features from each sample and feed these as imputs into a feed-forward neural network. I have already constructed the network using math-lab. However, learing to script in praat is proving to be quite a challenge given my time constraints. Some of my samples are 0.01 to 0.03 seconds in length, I was looking at standardising the duration for all samples using Pitch Synchronous OverLap-Add(PSOLA). However this will be very tedious if I were to do this for every sample. Is there any script that can read in all of my files and perform the operations in a batch mode? Any guidance will be surelly appreaciated. Regards.

• NSFormatter problem: not getting called for the empty string

  - by Enchilada

  I have created a custom formatter for my (read-only) table column. It looks like this: - (NSString *)stringForObjectValue:(id)anObject { NSAssert([anObject isKindOfClass:[NSString class]] && anObject != nil, @"invalid object"); if ([anObject isEqualToString:@""]) return @"EMPTY"; else return [anObject stringByAppendingString:@"++"]; } Very simple. The corresponding objects are just strings, so it's an string-to-string formatter. All non-empty string objects are returned with @"++" appended to them. Empty string objects should be turned into the @"EMPTY" string. The @"++" gets appended to non-empty strings just fine. The problem is, @"EMPTY" never gets shown! My formatter is never called by Cocoa when the underlying object is the empty string. The corresponding row just keeps being empty, instead of showing my requested @"EMPTY". Any ideas?

• last-child CSS issues

  - by Neurofluxation

  Hey you guys (and girls), I have implemented the following CSS: #tab-navigation ul li:last-child { background-image: url(../images/tabs-end.gif); background-repeat: no-repeat; color: #fff; display: block; border: 1px solid red; background-position: right; } However, for some reason this is not working at all in IE (surprise!) - I read (after some research) that IE requires a DOCTYPE, but I already have <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> defined. Any ideas peeps?

• How do you print a limited number of characters?

  - by Mike Pateras

  Sorry to put a post up about something so simple, but I don't see what I'm doing wrong here. char data[1024]; DWORD numRead; ReadFile(handle, data, 1024, &numRead, NULL); if (numRead > 0) printf(data, "%.5s"); My intention with the above is to read data from a file, and then only print out 5 characters. However, it prints out all 1024 characters, which is contrary to what I'm reading here. The goal, of course, is to do something like: printf(data, "%.*s", numRead); What am I doing wrong here?

• Visual Studio Symbols stored/loaded from wrong place

  - by werty0u

  Hello, I'm rather new to symbol servers and I've been experimenting with them and Visual Studio 2008 running Windows XP(SP3). I've encountered a wierd problem as my symbols are not being cached locally in the directory I've specified all the time. The possible reasons I have found for this si that the symbols(.pdb's) are being written to VS's IDE directory and/or the symbols are somehow being written in with the .exe, which I find odd since it should be read only. The symbols are being sent to the "server" I've specified so that part of the system shouldn't be the problem. Has anyone else had this type of issue before and/or maybe a solution to this problem? Thanks :)

• Why does ASP.Net rewrite relative paths for runat=server anchor controls?

  - by Atomiton

  I have my UserControls in a ~/Controls folder in my solution: /Controls/TheControl.ascx If specify the following: <a runat="server" href="./?pg=1">link text</a> ASP.Net seems to want to rewrite the path to point to the absolute location. For example, If the control is on site.com/products/fish/cans.aspx the link href will be rewritten to read <a href="../../Controls/?pg=1>link text</a> Why does Asp.Net rewrite these control paths, and is there an elegant way to fix it? I just want the anchor control to spit out exactly what I tell it to!!! Is that so hard?

• WPF DataGrid Vs Windows Forms DataGridView

  - by Mrk Mnl

  I have experience in WPF and Windows Forms, however have only used the Windows Forms DataGridView and not the WPF DataGrid (which was only included in .Net 4 or could be added to .Net 3.5 from Codeplex, I understand). I am about to devlop an app using one of these controls heavily for large amounts of data and have read performance is an issue with the WPF DataGrid so I may stick to the Windows Forms DataGridView.. Is this the case? I do not want to use a 3rd party control. Does the Windows Forms DataGridView offer significant performance over the WPF DataGrid for large amounts of data? If I were to use WPF I would prefer to use .Net 3.5S SP1, unless the DataGrid in the .Net 4 is significantly better? Also I want to use ADO with DataTable's which I feel is better suited to Windows Forms..

• Shell script not picking up password file...

  - by BigDogsBarking

  Running the below shell script seems to ignore the password file I'm feeding it. I'm continually prompted for it. If I enter it, the rest of the script goes without a hitch, but as I'm running it via cron, I really need to get it to read from the file... Any suggestions? #!/bin/sh p=$(<password.txt) set -- $p pass_phrase=$1 destination="/var/www/d" cd /var/sl/ for FILE in *.pgp; do FILENAME=${FILE%.pgp} gpg --passphrase "$pass_phrase" --output "$destination/$FILENAME" --decrypt "$FILE" rm -f $FILE done

• Replace a word in an XML file through StreamReader in XNA?

  - by kcoppock

  Okay, so this is sort of a hack...but it may have to be. I'm writing an app in XNA, which from my research into this problem apparently doesn't support XML version 1.1. I'm reading in the contents of an ePub document, and one of the newer books contains its content directory as a version 1.1 XML document. This causes my program to crash. However, the structure is the same as the rest, the only thing that should be keeping it from working is the hard-coded "1.0" in the XmlDocument class. Is it possible that I could read in the file from the stream, see if it contains: <?xml version="1.1" encoding="UTF-8" standalone="no"?> and simply replace it with "1.0"? Then I could pull it in as an XmlDocument. I'm not doing any writing to the file, or any complex structural reading, just looking for a few specific nodes, and pulling in the values, so I don't know what the ramifications of this would be.

• How to set the content of the $script_for_layout in cakephp?

  - by sipiatti

  Hi, I am learning cakephp in an autodidact manner and I am a complete newbie :) I am creating a simple application. Some logic work so now I going to dive into designing views and layouts. I read the docs and the tutorial but I could not find where to set the content of $script_for_layout. Especially I want to set a $html-css to create link in pages to the stylesheet. I found out that I could do it in directly in the layout template but I would like to create the same link in all pages/views/layouts to the stylesheet so I hope there is a simple way, and avoid to do this in all layouts and/or controllers

• Why is the CoreData stack in XCode's CoreData enabled template treated as private?

  - by rob5408

  In regards to XCode templates with CoreData enabled, I've read http://stackoverflow.com/questions/2729055/unclear-use-of-property-in-window-app-using-core-data which goes over the 'what' in the templates. But I am having an issue with the 'why'. By declaring the category in the implementation file, the CoreData accessors act like private methods. The problem with that is whenever you want to use CoreData elsewhere in your app, you need some extra code. I've figured you need to either supply your own method that exposes the managed object context, such as... - (NSManagedObjectContext *)getManagedObjectContext { return self.managedObjectContext; } ...which will allow other parts of your app to use it. Or you would need to jam pack your app delegate with specific methods to return managed objects, ie getProducts or setUser. Can anyone shed light on the reasoning here?

• Eclipse Class File Metadata

  - by Alex

  In Visual Studio, I can obtain a succinct list of public methods/members exposed in a class for which I do not have the source (i.e. bundled inside a DLL) by pressing F12 (GoToDefinition). Similarly, I am learning the Android API - in Eclipse. Jumping to an Android framework method definition produces decompilation output which is not intuitive to read, and is very verbose. To mimic results like Visual Studio, I am considering several options: How can I format the decompilation output to be 'cleaner' - I have looked through Eclipse's preferences menus and have not found a way to do this. How do I 'add corresponding source files' once Google provides it, so that jumping to definition yields the actual definition? Is there a plugin that does this already? I looked into Jadclipse, but that project has not been updated in several years, and is still a decompiler. Thank you in advance.
