  • Podcasts for Clojurians?

    - by Michiel Borkent
    I regularly listen to the podcasts DotNetRocks and Software Engineering Radio. Lately I have become more interested in Clojure. Are there any podcasts that target more toward the Clojure (more general FP/LISP/dynamic languages) audience? I know of some single podcast episodes but I'm looking for a podcast I can regularly listen to.

  • EF exception: Could not find file CodeGenerationSchema.xsd

    - by DK
    I'm using Entity Framework for a new project (VS 2008, .net 3.5 sp1) and "reasonably happy" with it, especially compared to dataset-based solutions. One of recurring annoyances is "Could not find file CodeGenerationSchema.xsd" exception during application startup. Exception seems to re-appear rather frequently after changes to the model. Googling gives temporary and strange workarounds for this error: Delete .suo file, or Set Options Debugging General Enable Just My Code = On May be someone have more permanent, straightforward fix or can explain the reason of this issue.

  • How is Java Process.getOutputStream() Implemented?

    - by Amit Kumar
    I know the answer depends on the particular JVM, but I would like to understand how it is usually implemented? Is it in terms of popen (posix)? In terms of efficiency do I need to keep something in mind (other than using a Buffered stream as suggested by the javadoc). I would be interested to know if there is a general reference about implementations of JVMs which answers such questions.

  • Sum up values in an array list in java

    - by user1449997
    Hello to all tired and frustrated programmers, There is a problem I can't solve: In my array list there are Object arrays with the length of three and always on the last cell of the array there is a double. I need a loop which goes through the array list and sums up all doubles. (I need also some other thing from the arrays so a general idea how to loop through an array list would be perfect :-)) Any ideas? Thanks for your help, Greetings Demian

  • what are the "must have" JQuery plugins?

    - by Don
    Hi, I'd like to know what are the most useful JQuery plugins. I'm particularly interested in those which are likely to be useful in general UI development, such as Tablesorter, rather than those which serve uncommon needs. If you could provide a very brief description of the plugin's purpose, that would be really helpful. Thanks, Don

  • Clojure vars and Java static methods

    - by j-g-faustus
    I'm a few days into learning Clojure and are having some teething problems, so I'm asking for advice. I'm trying to store a Java class in a Clojure var and call its static methods, but it doesn't work. Example: user=> (. java.lang.reflect.Modifier isPrivate 1) false user=> (def jmod java.lang.reflect.Modifier) #'user/jmod user=> (. jmod isPrivate 1) java.lang.IllegalArgumentException: No matching method found: isPrivate for class java.lang.Class (NO_SOURCE_FILE:0) at clojure.lang.Compiler.eval(Compiler.java:4543) From the exception it looks like the runtime expects a var to hold an object, so it calls .getClass() to get the class and looks up the method using reflection. In this case the var already holds a class, so .getClass() returns java.lang.Class and the method lookup obviously fails. Is there some way around this, other than writing my own macro? In the general case I'd like to have either an object or a class in a varible and call the appropriate methods on it - duck typing for static methods as well as for instance methods. In this specific case I'd just like a shorter name for java.lang.reflect.Modifier, an alias if you wish. I know about import, but looking for something more general, like the Clojure namespace alias but for Java classes. Are there other mechanisms for doing this? Edit: Maybe I'm just confused about the calling conventions here. I thought the Lisp (and by extension Clojure) model was to evaluate all arguments and call the first element in the list as a function. In this case (= jmod java.lang.reflect.Modifier) returns true, and (.getName jmod) and (.getName java.lang.reflect.Modifier) both return the same string. So the variable and the class name clearly evaluate to the same thing, but they still cannot be called in the same fashion. What's going on here? Edit 2 Answering my second question (what is happening here), the Clojure doc says that If the first operand is a symbol that resolves to a class name, the access is considered to be to a static member of the named class... Otherwise it is presumed to be an instance member http://clojure.org/java_interop under "The Dot special form" "Resolving to a class name" is apparently not the same as "evaluating to something that resolves to a class name", so what I am trying to do here is something the dot special form does not support.

  • Efficiently solving sparse matrices

    - by anon
    For solving spare matrices, in general, how big does the matrix have to be (as a rule of thumb) for methods like congraduate descent to be faster than brute force solvers (that do not take advantage o sparsity)?

  • Corporate developers: Do you feel your code is adding value to the company?

    - by Pierreten
    I'm going through a phase where I'm not being productive at all. I find it hard to justify to myself getting paid six figures to sit in front of my computer and act busy. Management is completely disengaged, and the users as well. What do you do in this type of situation? I've taken to learning some deeper aspects of .Net and software construction in general, but don't like the feeling that I'm stiffing my employer.

  • Moving a turtle to the center of a circle.

    - by Maggie
    I've just started using the turtle graphics program, but I can't figure out how to move the turtle automatically to the center of a circle (no matter where the circle is located) without it drawing any lines. I thought I could use the goto.() function but it's too specific and I need something general.

  • Memory Leak from Foundation & CFNetwork Library

    - by Lakshmie
    I am using instruments to resolve memory leak issues for an app in iPhone. I just wanted to know if I have to resolve the leaks coming from Foundation and CFNetwork Libraries. Specifically, the leaks are from: 1. NSCFString 2. NSConcreteData 3. General Block-3584 Since they do not directly point to the code that I have written, how should I resolve them, if I have to? Thanks.

  • Why is Visual Basic bad?

    - by Mike
    Why do programmers consider Visual Basic a bad language? Putting aside any gripes with Microsoft or with proprietary/non-free software in general, and looking the language itself. Syntax, style, etc. I have just started using it, and find the syntax rather terrible. But I'm wondering what are the most common specific problems.

  • How to set a keybinding which is valid in all modes in Emacs

    - by AnotherEmacsLearner
    Hi, I've configured my emacs to use M-j as backward-char by (global-set-key (kbd "M-j") 'backward-char) ; was indent-new-comment-line in my .emacs file. This works fine in many modes (text/org/lisp). But in c++-mode & php-mode it is bound to the default c-indent-new-comment-line How can I bind M-j to use backward-char in these modes too. And in general for ALL modes. Thanks, AnotherEmacsLearner

  • New to asp.net. Need help debugging this email form.

    - by Roeland
    Hey guys, First of all, I am a php developer and most of .net is alien to me which is why I am posting here! I just migrated over a site from one set of webhosting to another. The whole site is written in .net. None of the site is database driven so most of it works, except for the contact form. The output on the site simple states there was an error with "There has been an error - please try to submit the contact form again, if you continue to experience problems, please notify our webmaster." This is just a simple message it pops out of it gets to the "catch" part of the email function. I went into web.config and changed the parameters: <emailaddresses> <add name="System" value="[email protected]"/> <add name="Contact" value="[email protected]"/> <add name="Info" value="[email protected]"/> </emailaddresses> <general> <add name="WebSiteDomain" value="hoyespharmacy.com"/> </general> Then the .cs file for contact contains the mail function EmailFormData(): private void EmailFormData() { try { StringBuilder body = new StringBuilder(); body.Append("Name" + ": " + txtName.Text + "\n\r"); body.Append("Phone" + ": " + txtPhone.Text + "\n\r"); body.Append("Email" + ": " + txtEmail.Text + "\n\r"); body.Append("Fax" + ": " + txtEmail.Text + "\n\r"); body.Append("Subject" + ": " + ddlSubject.SelectedValue + "\n\r"); body.Append("Message" + ": " + txtMessage.Text); MailMessage mail = new MailMessage(); mail.IsBodyHtml = false; mail.To.Add(new MailAddress(Settings.GetEmailAddress("System"))); mail.Subject = "Contact Us Form Submission"; mail.From = new MailAddress(Settings.GetEmailAddress("System"), Settings.WebSiteDomain); mail.Body = body.ToString(); SmtpClient smtpcl = new SmtpClient(); smtpcl.Send(mail); } catch { Utilities.RedirectPermanently(Request.Url.AbsolutePath + "?messageSent=false"); } } How do I see what the actual error is. I figure I can do something with the "catch" part of the function.. Any pointers? Thanks!
