  • Core Data (NSFetchedResultsController) displaying one row per section

    - by Urizen
    I have a CoreData application which uses NSFetchedResultsController. NSFetchedResultsController is useful in that it allows me to access the fetched objects more easily etc. but I find that I have problems with the following: I get a crash when I display a single row for each section (irrespective of the number of actual rows present) as a summary of the information in that section (e.g. showing a statistical analysis of the data contained in the fetched rows for that section). I understand that the NSFetchedResultsControllerDelegatemethods have to agree with the number of rows reported per section by the UITableView Delegate method but I would like to be able to fetch all of the records for each section without necessarily displaying each of the rows. The above causes me inconsistency crashes, when I try to insert or delete data for a section, which reports that the number of rows for each section is not as it should be given the number of insertions/deletions. Is there any way I can do what I'm trying to achieve? Thanks for any help.

  • How do I upgrade my MacPorts Perl installation?

    - by sfactor
    I have installed MacPorts in my MacBook Pro with Snow Leopard. I hadn't explicitly installed perl there but I guess it either came installed with the default macports install or was installed as a dependency by any other port I installed. I want to upgrade the Perl v5.8.9 there with the latest stable Perl version. Whichever it may be currently (I see it is 5.12.2). So, my question is simply how do I do a complete replacement of the old Perl with the new in macports. Will sudo port upgrade perl5 work or do I need to do something else as well. I just wanted to make sure this was the right command so as to avoid screwing up my macports install.

  • Getting started with modern software architecture and design using a book

    - by bitbonk
    I am a rather oldschool developer with some basic knowledge of software design principles and a good background on classic (gof) design patterns. While I continue my life as such I see lots of strange buzzwords emerge: Aspectoriented Design, Componentoriented Design, Domain Driven Design, Domain Specific Languages, Serviceoriented (SOA) Design, Test Driven Design, Extreme Programming, Agile Development, Continuous Integration, Dependency Injection, Software Factories ... Is there good book around that I can take with me on a roadtrip while it is taking me on a trip through all (most) of the above, delivering an 10,000 foot view on modern software archiceture and desing principles and approaches.

  • .NET remoting manual configuration

    - by Quandary
    Question: In .NET remoting, I configure the client like this from a config file RemotingConfiguration.Configure("AsyncRemoteAPIclient.exe.config", False) Dim obj As New RemoteAPI.ServiceClass() (with this AsyncRemoteAPIclient.exe.config) <system.runtime.remoting> <application> <client> <wellknown type="RemoteAPI.ServiceClass, ServiceClass" url="http://localhost:8080/ServiceClass.rem" /> </client> <channels> <channel ref="http" port="0" /> </channels> </application> But when I replace the config file with manual configuration with the below code, it stops working, and starts complaining "ServiceClass or dependency not found". Dim chan As New System.Runtime.Remoting.Channels.Http.HttpChannel(0) System.Runtime.Remoting.Channels.ChannelServices.RegisterChannel(chan, False) ' Create an instance of the remote object Dim obj As RemoteAPI.ServiceClass obj = CType(Activator.GetObject(GetType(RemoteAPI.ServiceClass), "http://localhost:8080/ServiceClass.rem"), RemoteAPI.ServiceClass) What's wrong ?

  • Templated Control databinding to custom properties

    - by Dan Wray
    Is there some trick that I'm missing here? I've created a templated control, very simple. One single property on it, and I'd like to databind from the (viewmodel/datacontext of the) page in which it's hosted to a custom property on the control. The property will eventually be a vector type object, defining the position of the control, however in an attempt to get this to work I've tried reducing it to a basic string property. Each time I'm faced with "Set property 'SimpleGame.Classes.Sprite.Property' threw an exception.". I can't even catch the exception in a debug session, the set property code is not being executed. Do I need to use a dependency / attached property or something? I wouldn't have thought so...

  • How to find a coding buddy

    - by Lirik
    I was reading Jeff Atwood's blog and he mentioned that he was suffering from code-paralysis (he called it analysis paralysis, but I feel like it's also code paralysis) when he didn't have a code buddy: http://www.codinghorror.com/blog/ Unfortunately I think that Jeff has set the bar a bit high, because he only works with developers who are really amazing. The only reason really amazing developers would work with me is if I was really amazing too, but sometimes I don't feel that amazing... the only thing I feel is that if I had a coding buddy I could be amazing :). I'm working on a project and I don't have many friends that are programmers, let alone friends that have time to spend on extracurricular activities. Jeff seems to have been able to find like-minded people that are actually willing to work together. I feel like I'm in a code-paralysis stage too and I need some coding buddies, where would I find some? How would I approach them?

  • Downloading Eclipse's Source Code

    - by digiarnie
    I'm doing a study on large Java projects and would like to view the source code for Eclipse. I have gone to this url (http://wiki.eclipse.org/index.php/CVS_Howto) and figured that the most useful cvs repository for me to look at would be this one: :pserver:[email protected]:/cvsroot/eclipse (The Eclipse platform project) However, when looking at this repository, it has so many modules! Which modules should I be trying to check out? I don't necessarily want to build the IDE from source, however, I just want to get the core Eclipse code base to perform some analysis. Would I just check out any modules starting with "org.eclipse..."? Should I be checking out any of the others? Or is there an easier way to get the source? I read somewhere that you can get the source from the binary version of Eclipse but I am unsure where to find the source.

  • Java code to convert a list of dependencies into a build order?

    - by Egon Willighagen
    Given I have a list of dependencies, like: module1 module2 dependsOn module1 module3 dependsOn module1 module4 dependsOn module3 I would like to create a build order where each build step is found on one line, and each line contains a list of one or more modules which can be compiled at the same time, and which only depend on modules compiled earlier. So, for the above data set, create a list like: module1 module2,module3 module4 Now, this is basically just a problem of creating a directed graph, and analyzing it. Now, I am using Ant, and would very much like to use something off-the-shelf... what is the minimum of custom code I need to have it create such a dependency-aware build list starting from the given input? BTW, these modules are actually custom modules, so maven will not work.

  • How can I specifiy JUnit test dependencies?

    - by Egon Willighagen
    Our toolkit has over 15000 JUnit tests, and many tests are known to fail if some other test fails. For example, if the method X.foo() uses functionality from Y.foo() and YTest.testFoo() fails, then XTest.testFoo() will fail too. Obviously, XTest.testFoo() can also fail because of problems specific to X.foo(). While this is fine and I still want both tests run, it would be nice if one could annotate a test dependency with XTest.testFoo() pointing to YTest.testFoo(). This way, one could immediately see what functionality used by X.foo() is also failing, and what not. Is there such annotation available in JUnit or elsewhere? Something like: public YTests { @Test @DependsOn(method=org.example.tests.YTest#testFoo) public void testFoo() { // Assert.something(); } }

  • what is order notation f(n)=O(g(n))?

    - by Lopa
    2 questions: question 1: under what circumstances would this[O(f(n))=O(k.f(n))] be the most appropriate form of time-complexity analysis? question 2: working from mathematical definition of O notation, show that O(f(n))=O(k.f(n)), for positive constant k.? My view: For the first one I think it is average case and worst case form of time-complexity. am i right? and what else do i write in that? for the second one I think we need to define the function mathematically, so is the answer something like because the multiplication by a constant just corresponds to a readjustment of value of the arbitrary constant 'k' in definition of O.

  • GNU ld removes section

    - by Jonatan
    I'm writing a boot script for an ARM-Cortex M3 based device. If I compile the assembler boot script and the C application code and then combine the object files and transfer them to my device everything works. However, if I use ar to create an archive (libboot.a) and combine that archive with the C application there is a problem: I've put the boot code in a section: .section .boot, "ax" .global _start _start: .word 0x10000800 /* Initial stack pointer (FIXME!) */ .word start .word nmi_handler .word hard_fault_handler ... etc ... I've found that ld strips this from the final binary (the section "boot" is not available). This is quite natural as there is no dependency on it that ld knows about, but it causes the device to not boot correctly. So my question is: what is the best way to force this code to be included?

  • Static lib that links another static lib and qmake? Odd linking error

    - by Dan O
    I have two qt .pro files, both using the lib TEMPLATE and staticlib CONFIG. The first library (lets call it 'core') is a dependency for the second lib (I'll call it 'foo'). In fact, there's a class in foo that extends a class in core, I will call this class Bar. When I instantiate the class (which is defined and implemented in foo, but extends a class (Bar) from core) in another project (not a lib) I get the following linking error: /usr/bin/ld: Undefined symbols: Bar::Bar() Basically, the linker cannot find the class in the core lib that has been derived in the foo lib, but ONLY when I instantiate the class in a third project that is using both libs. Is this behaviour expected? Regards, Dan O Update: I fixed it by directly invoking the Bars constructor in the third project before using derived class... does anyone know why I need to do this?

  • What is the difference between Multiple R-squared and Adjusted R-squared in a single-variate least s

  • Creating a "less"-like console pager interface for pysqlite3 database

    - by Eric
    I would like to add some interactive capability to a python CLI application I've writen that stores data in a SQLite3 database. Currently, my app reads-in a certain type of file, parses and analyzes, puts the analysis data into the db, and spits the formatted records to stdout (which I generally pipe to a file). There are on-the-order-of a million records in this file. Ideally, I would like to eliminate that text file situation altogether and just loop after that "parse and analyze" part, displaying a screen's worth of records, and allowing the user to page through them and enter some commands that will edit the records. The backend part I know how to do. Can anyone suggest a good starting point for creating that pager frontend either directly in the console (like the pager "less"), through ncurses, or some other system?

  • C# how to correctly dispose of an SmtpClient?

    - by JL
    VS 2010 code analysis reports the following: Warning 4 CA2000 : Microsoft.Reliability : In method 'Mailer.SendMessage()', object 'client' is not disposed along all exception paths. Call System.IDisposable.Dispose on object 'client' before all references to it are out of scope. My code is : public void SendMessage() { SmtpClient client = new SmtpClient(); client.Send(Message); client.Dispose(); DisposeAttachments(); } How should I correctly dispose of client? Update: to answer Jons question, here is the dispose attachments functionality: private void DisposeAttachments() { foreach (Attachment attachment in Message.Attachments) { attachment.Dispose(); } Message.Attachments.Dispose(); Message = null; }

  • Ninject: Dynamically loading modules in Silverlight

    - by joblot
    The reason I want to load modules dynamically is to avoid circular dependency issue. I have following layers View -- ViewModel -- DataProvider -- ServiceClient (wcf proxies). Now I want a static IoC container that can be shared across these layers. I want to make my View testable and to do that I’ll have to inject the various dependencies in various layers and mock out those dependencies as well. Now issue I am facing is where to declare and load ninject modules. i also realised in Silverlight version of Ninject there is no version of Load which take string arugment, which can be used to load the modules dynamically Load("*.dll"). How can I achieve dynamic loading in Silverlight Thanks

  • Classloader problems Tomcat 6 javagent

    - by alecswan
    I am using Salve Dependency Injection library that instruments the byte code of the web application. I specified -javaagent in Tomcat VM options and pointed it to the Salve agent jar. The agent jar gets loaded, but then it throws a java.lang.NoClassDefFoundError unable to find classes that are in other Salve jars which are located in WEB-INF/lib folder of my web app. I can solve this problem by putting those JARs in Tomcat/endorsed folder. However, some of those jars depend on third-party libraries, such as Spring and servlet-api.jar. Therefore, I am forced to put all these dependencies in Tomcat/endorsed as well. Could anybody suggest a better way for handling dependencies of a Tomcat javaagent? Thanks.

  • How can I handle template dependencies in Template Toolkit?

    - by Smack my batch up
    My static web pages are built from a huge bunch of templates which are inter-included using Template Toolkit's "import" and "include", so page.html looks like this: [% INCLUDE top %] [% IMPORT middle %] Then top might have even more files included. I have very many of these files, and they have to be run through to create the web pages in various languages (English, French, etc., not computer languages). This is a very complicated process and when one file is updated I would like to be able to automatically remake only the necessary files, using a makefile or something similar. Are there any tools like makedepend for C files which can parse template toolkit templates and create a dependency list for use in a makefile? Or are there better ways to automate this process?

  • Tool for parsing smtp logs that finds bounces

    - by Željko Filipin
    Our web application sends e-mails. We have lots of users, and we get lots of bounces. For example, user changes company and his company e-mail is no longer valid. To find bounces, I parse smtp log file with log parser. Some bounces are great, like 550+#[email protected]. There is [email protected] in bounce. But some do not have e-mail in error message, like 550+No+such+recipient. I have created simple ruby script that parses logs (uses log parser) to find which mail caused something like 550+No+such+recipient. I am just surprised that I could not find a tool that does it. I have found tools like zabbix and splunk for log analysis, but they look like overkill for such simple task. Anybody knows a tool that would parse smtp logs, find bounces and e-mails that cause them? Edit: smtp server is microsoft smtp server.

  • Are there macro facility for Java or C#?

    - by h2g2java
    Macros are useful. Therefore, I occasionally bemoan the absence of macros in Java and C#. Macros allow me to force in-line but allow me the code-manageability of non-macro code. Is there any Java- or C#-based project/product somewhere out there that effectively allow macros or specifying in-line expansion. I am thinking of something like @macro public void hello(int x){ ... } or when I call a method, an @inline annotation preceding the call would effect the called-method to be in-lined. or, should I need to know that I should just trust the compiler to make the best the decision for me that at the best of its analysis it might in-line a call. I hope this question will not lead to debating the pro/cons/usefulness of macros.

  • How can I loop through variables in SPSS? I want to avoid code duplication.

    - by chucknelson
    Is there a "native" SPSS way to loop through some variable names? All I want to do is take a list of variables (that I define) and run the same procedure for them: pseudo-code - not really a good example, but gets the point across... for i in varlist['a','b','c'] do FREQUENCIES VARIABLES=varlist[i] / ORDER=ANALYSIS. end I've noticed that people seem to just use R or Python SPSS plugins to achieve this basic array functionality, but I don't know how soon I can get those configured (if ever) on my installation of SPSS. SPSS has to have some native way to do this...right?

  • Graphical Programming Language

    - by prosseek
    In control engineering or instrumentation, I see Simulink or LabVIEW(G) is pretty popular. In ESL design, I see that Agilent SystemVue is gaining some popularity. If you see the well established compiler theroy, almost 100% is about the textual language. But how about the graphical language? Is there any noticable research or discussion about the graphical programming language? In terms of Theory about Graphical Language - syntactic/semantic analysis and whatever relevant expressiveness (Actually, I asked a question about it at SO - http://stackoverflow.com/questions/2427496/what-do-you-mean-by-the-expressiveness-in-programming-lanuguage) Possibility of the Graphical language ... Or what do you think about the Graphical Programming Language?

  • ER Diagram flaws

    - by spacker_lechuck
    I have the following ER Diagram for a bank database - customers may have several accounts, accounts may be held jointly by several customers, and each customer is associated with an account set and accounts are members of one or more account sets. What design rules are violated? What modifications should be made and why? So far, a few flaws I'm not sure about are: 1) Redundant owner-address attribute in AcctSets Entity. 2) This ER does not include accounts with multiple owners with different addresses. My Question is: How would I go about fixing these flaws and/or other flaws that I may be missing from my analysis? Thanks!

  • Ivy: Publishing all artefacts in a directory

    - by Dave Flowers
    I'm looking to move to Apache Ivy for dependency management on one of our existing projects. The project publishes many artefacts, and the artefacts it produces are likely to change in the future, so I don't want to enumerate all of the publications in the ivy.xml file -- I'd like Ivy to just publish all the files in a given directory. I considered auto-generating a list of the files built and using XSLT to insert it into the ivy.xml, but that seems a little cumbersome for what I'd expect to be a reasonably common requirement. Is there a better way to do this? Can Ivy pick up all the files in a directory and ignore the publications in the Ivy file? Or is there some way to get Ivy to use different files for publication and for fetching, so I can avoid having to use XSLT to merge the files.
