  • rails: actionmailer not logging

    - by bandhunt
    I'm setting up actionmailer in rails but don't see where it logs errors and therefore cannot troubleshoot. I've got the delivery_errors turned on in environments/development.rb: config.action_mailer.raise_delivery_errors = true I'm not seeing anything logged in development.log related to emailing. Does actionmailer log to somewhere else or what am I missing? Thanks!

  • Official multiple python versions on the same machine?

    - by drozzy
    Is there an official documentation on python website somewhere, on how to install and run multiple versions of python on the same machine? On linux? I can find gazillions of blog posts and answers - but I want to know if there is a "standard" official way of doing this? Or is this all dependent on OS?

    - by Nimbuz
    My Python module has a list that contains all the data I want to save as a .txt file somewhere. The list contains several tuples like so: list = [ ('one', 'two', 'three'), ('four', 'five', 'six')] How do I print the list so each tuple item is separated by a tab and each tuple is separated by a newline? Thanks

  • OpenGL Motion blur with the accumulation buffer

    - by Klaus
    Hello, I'm trying to achieve a motion blur effect in my OpenGL application. I read somewhere this solution, using the accumulation buffer: glAccum(GL_MULT, 0.90); glAccum(GL_ACCUM, 0.10); glAccum(GL_RETURN, 1.0); glFlush(); at the end of the render loop. But nothing happens... What I am missing ?

  • How do I use the Windows API Code Pack in VB.net 2010 Express?

    - by Josh
    Hi all, I recently downloaded the Windows API code pack for .net, and seeing there was VB.net examples inside there, I opened them up. Upon building I get a warning that the referenced components 'Core' and 'Shell' could not be found. Looking in the code pack folder I see there are no DLLs at all, but instead a whole load of C# sources. Do I have to download C# Express (which I want to avoid) to use the code pack or are there precompiled DLLs somewhere?

  • Linux's thread local storage implementation

    - by anon
    __thread Foo foo; How is "foo" actually resolved? Does the compiler silently replace every instance of "foo" with a function call? Is "foo" stored somewhere relative to the bottom of the stack, and the compiler stores this as "hey, for each thread, have this space near the bottom of the stack, and foo is stored as 'offset x from bottom of stack'"?

  • How to know a device's name from its device ID in OS X?

    - by yangumi
    Hi all, I'm writing a program in OS X that receives click events from a mouse and a touchpad. When the user clicks at somewhere, the OS sends the device ID, which is just an int, and the position of the cursor to my callback function. I want to know if the click event comes from mouse or touchpad. So, how can I know the device's name from its device ID? Thank you! (I'm sorry for my poor English.)

  • Debugging in Flash CS4

    - by danyal
    Is a watch list hidden away somewhere in the AS3 debugger in Flash CS4? Sorry for asking a simple question like this here - I did spend a while looking around the net first. It's much easier to find the watch list in the AS2 debugger. Thanks, Dan

  • Is there a working example of using WebDAV for querying Exchange server for calendar items?

    - by Lasse V. Karlsen
    I have tried to hack together a small test project, but it fails with "400 Bad Request" so I'm pretty sure I have done something very basic wrong, but the examples I've found are all in the form of questions, only showing minor pieces of the puzzle, such as a request XML for public folders or whatnot. Is there a complete example somewhere where I can just put in my username and servername and it would list the calendar items in my calendar? This is for C# 3.0/4.0.

  • Removing the default pages when adding a domain via Plesk

    - by ChrisS
    Hi, whenever I add a new domain into my new Plesk control panel on my dedicated server it creates a whole bunch of test files in the cgi-bin, httpdocs and httpsdocs. There must be some setting somewhere where I can tell Plesk not to do this? I've done a good Google search but must now turn to the StackOverflow masses :) Yours, Chris

  • log4j properties file: how to configure ?

    - by EugeneP
    Is it right that the procedure of using log4j looks like this: 1) put a .properties file somewhere in a project folder 2) in an initialization method, that runs only once, invoke PropertyConfigurator.configure("path_to_file"); 3) in every method we need to use logger we define a static logger variable and simply invoke getLogger(class) I'm asking you this: what if the initialization module is not defined? Where to put "log4j.properties" file so that we wouldn't need to invoke propertyconfigurator.configure at all, or if it's not possible, is it ok to invoke PropertyConfigurator.configure("path_to_file") in every method that uses a logger?

  • Help getting started with MEF

    - by SteveCl
    Hi, I was reading somewhere that with MEF I can simply drop a dll into a directory and my application (with some MEF magic) will be able to read it and execute the code in it? Hopefully only classes that implement an interface that I define?? Can someone help me to get going, with some links maybe for my problem. I've looked through some of the docs, but nothing seems to be what I'm after and its tricky when I don't know exactly what to search on... Thx S

  • Localizing MVVM based WPF applications

    - by bitbonk
    What would be a good aproach to localize a MVVM based WPF allication that can change its language at runtime? Of course I could create a string property in the ViewModel for each and every string that is displayed somewhere in the View but that seems rather tedious to me. Is there a common approach/best practice for this?

  • Configuring jstree right-click contextmenu for different node types

    - by MGOwen
    I've seen an example somewhere online showing how to customise the appearance of jstree's right-click context menu (using contextmenu plugin). For example, allow my users to delete "documents" but not "folders" (by hiding the "delete" option from the context menu for folders). Now I can't find that example. Can anyone point me in the right direction? The official documentation didn't really help.

  • Is using the Class instance as a Map key a best practice?

    - by Pangea
    I have read somewhere that using the class instances as below is not a good idea as they might cause memory leaks. Can someone tell me if if that is a valid statement? Or are they any problems using it this way? Map<Class<?>,String> classToInstance=new HashMap(); classToInstanceMap.put(String.class,"Test obj");
