  • How to add a custom loglevel to Python's logging facility

    - by tuergeist
    Hi, I'd like to have loglevel TRACE (5) for my application as I don't think that debug() is enought. Additionally log(5, msg) isn't what I want. The question is, how can I add a custom log level to a Python logger? Actually I've a mylogger.py with the following content: import logging @property def log(obj): myLogger = logging.getLogger(obj.__class__.__name__) return myLogger In my code I use it in the following way: class ExampleClass(object): from mylogger import log def __init__(self): '''The constructor with the logger''' self.log.debug("Init runs") Now I'd like to call self.log.trace("foo bar") Thanks in advance for your help.

  • jQuery .click() not binding properly

    - by Chris
    I want to perform some action when a link is clicked, I am using the following code to achieve this however it rarely works. If I click the link it usually refreshes the page, and 1/10 times it'll actually pop up "Hi". What is wrong? $(document).ready(function() { $('#slconfiglink').click(function() { alert("hi"); return false; }); }); HTML: <ul> <li><a href="" id="slconfiglink">Config 1</a></li> </ul>

  • Preallocating memory with C++ in realtime environment

    - by Elazar Leibovich
    I'm having a function which gets an input buffer of n bytes, and needs an auxillary buffer of n bytes in order to process the given input buffer. (I know vector is allocating memory at runtime, let's say that I'm using a vector which uses static preallocated memory. Imagine this is NOT an STL vector.) The usual approach is void processData(vector<T> &vec) { vector<T> &aux = new vector<T>(vec.size()); //dynamically allocate memory // process data } //usage: processData(v) Since I'm working in a real time environment, I wish to preallocate all the memory I'll ever need in advance. The buffer is allocated only once at startup. I want that whenever I'm allocating a vector, I'll automatically allocate auxillary buffer for my processData function. I can do something similar with a template function static void _processData(vector<T> &vec,vector<T> &aux) { // process data } template<size_t sz> void processData(vector<T> &vec) { static aux_buffer[sz]; vector aux(vec.size(),aux_buffer); // use aux_buffer for the vector _processData(vec,aux); } // usage: processData<V_MAX_SIZE>(v); However working alot with templates is not much fun (now let's recompile everything since I changed a comment!), and it forces me to do some bookkeeping whenever I use this function. Are there any nicer designs around this problem?

    Hi All I can't seem to get this working, some help would be greatly appreciated. I have a page with the following code: $('.editname').click(function (e) { var src = "test.html"; $.modal('<iframe src="' + src + '" height="480" width="640" style="border:0">', { closeHTML:"<div class='no simplemodal-close'>Close</div>", containerCss:{ backgroundColor:"#fff", border:"10px solid #333", height:480, padding:"10px", width:640 }, opacity:50, overlayCss: {backgroundColor:"#fff"}, onShow: function (dialog) { $('.saveit', dialog.data[0]).click(function () { // close the dialog $.modal.close(); }); } }); }); The code for test.html (the contents of the modal window) is: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <title>Untitled Document</title> <link href="css/reset.css" rel="stylesheet" type="text/css" /> <link href="css/layout.css" rel="stylesheet" type="text/css" /> <link href="css/text.css" rel="stylesheet" type="text/css" /> </head> <body> <h1>Test</h1> <div class='pointer spacertop'><a href="#" class="saveit">Save</a></div> </body> </html> The modal window appears, however clicking on the Save button (class saveit) in the modal window does not fire the click function. It does nothing. Please help. Thank you in advance.

  • Explain DLL Dependencies to a lay person

    - by wheaties
    This follows from a previous posting I made about lack of a clean test machine for software installations. I'm doing a bad job of explaining how DLL dependencies work and how some machines might not have the right libraries at the time of installation. The problem is that it's being viewed as a defect with the build process. I'm trying to educate the higher ups that it's not the build process per se but rather the installation process which is to blame. Here's a quote from my boss relating subcontractor work to our work to put it into perspective: I'm not a software person. All I see is that when they hand something to us it just works but when we hand something to the client there's all sorts of problems. There must be something wrong with how you're building the code. It's very easy to see how someone who is smart (scarily smart) could come to the wrong conclusion. So how would you explain the whole DLL dependency issue?

  • iPhone: Prevent View from Rotation

    - by Matthias
    Hi, I use a UITabBarController with 4 views. The first of those 4 views should be able to rotate, the other three not. And now the problem is, when having a tab bar controller you have to set all used views to rotatable (i.e. returning TRUE in shouldAutorotateToInterfaceOrientation). So, my question is now, can I prevent the three views from rotation even though the shouldAutorotateToInterfaceOrientation method returns TRUE? Thanks for your help. Regards Matthias

  • .classpath and .project - check into version control or not?

    - by amarillion
    I'm running an open source java project that consists of multiple modules in a tree of dependencies. All those modules are subdirectories in a subversion repository. For newcomers to our project, it's a lot of work to set all that up manually in eclipse. Not all our developers use eclipse. Nevertheless, we're considering to just check in the .classpath and .project files to help newcomers to get started. Is this a good idea? Or would that lead to constant conflicts in those files? Is there an alternative way to make the project easy to set up on eclipse?

  • How to avoid nested functions when using AJAX?

    - by Fletcher Moore
    Sequential Asynchronous calls are gross. Is there a more readable solution? The problem is this is hard to follow: ajaxOne(function() { // do something ajaxTwo(function() { // do something ajaxThree() }); }); where the anonymous functions are callbacks that are called on server response. I'm using a third party API to make the AJAX calls, so I need a generic solution.

  • RewriteRule - how to redirect from a folder within a folder to a new domain?

    - by eb_Dev
    Hi, I've been struggling with the following rule: RewriteRule ^subdomains/example.com/(.*)$ http://www.example.com/$1 [R=301,L] I'm trying to redirect anything that occurs after the folder /subdomains/example.com/ to http://www.example.com/ whilst including any filename or extra folder path information. E.g: www.olddomain.com/subdomains/example.com/index.html - www.example.com/index.html www.olddomain.com/subdomains/example.com/files/ - www.example.com/files/ www.olddomain.com/subdomains/example.com/files/index.html - www.example.com/files/index.html Any help would be greatly appreciated!

  • Best practices on using URIs as parameter value in REST calls.

    - by dafmetal
    I am designing a REST API where some resources can be filtered through query parameters. In some cases, these filter values would be resources from the same REST API. This makes for longish and pretty unreadable URIs. While this is not too much of a problem in itself because the URIs are meant to be created and manipulated programmatically, it makes for some painful debugging. I was thinking of allowing shortcuts to URIs used as filter values and I wonder if this is allowed according to the REST architecture and if there are any best practices. For example: I have a resource that gets me Java classes. Then the following request would give me all Java classes: GET http://example.org/api/v1/class Suppose I want all subclasses of the Collection Java class, then I would use the following request: GET http://example.org/api/v1/class?has-supertype=http://example.org/api/v1/class/collection That request would return me Vector, ArrayList and all other subclasses of the Collection Java class. That URI is quite long though. I could already shorten it by allowing hs as an alias for has-supertype. This would give me: GET http://example.org/api/v1/class?hs=http://example.org/api/v1/class/collection Another way to allow shorter URIs would be to allow aliases for URI prefixes. For example, I could define class as an alias for the URI prefix http://example.org/api/v1/class/. Which would give me the following possibility: GET http://example.org/api/v1/class?hs=class:collection Another possibility would be to remove the class alias entirely and always prefix the parameter value with http://example.org/api/v1/class/ as this is the only thing I would support. This would turn the request for all subtypes of Collection into: GET http://example.org/api/v1/class?hs=collection Do these "simplifications" of the original request URI still conform to the principles of a REST architecture? Or did I just go off the deep end?

  • Script tag in ASPX page is written partially (output stopped at random)

    - by Nir
    I have an aspx page where I put a script tag with .net "if" and "else". The problem is that the output gets cut at random points each time. Sometimes it's ok, sometimes I get cropped output. The code itself (Simplified example): <body id="body" runat="server"> <form id="form1" runat="server">some HTML <script type="text/javascript"> window.addEvent('domready', function() { var x = "nothing"; <% if(someCondition){%> x = "2"; <%} else {%> x = "3"; <%}%> }); </script> </form> </body> The cropped output: <body id="body" runat="server"> <form id="form1" runat="server">some HTML <script type="text/javascript"> window.addEvent('domready', function() { var x = "nothi </script> </form> </body> Does anybody have a clue?

  • POST Ajax call results in not found using jqGrid and ASP.NET MVC 2 on IIS6

    - by Dan
    This is puzzling me. I deployed an MVC 2 application to IIS6 and everything works fine except for my jqGrid calls to get data. All is well on my development machine, but here are the two URLs I'm working with Local dev web server: POST http://localhost:port/Ctrl.mvc/JsonMethod IIS6 (notice https - not sure if that matters) POST https://www.domain.com/AppName/Ctrl.mvc/JsonMethod The latter URL results in a HTTP 404, which is really confusing as all works well on my local machine. The JsonMethod is properly declared with [AcceptVerbs(HttpVerbs.Post)] Let me know if any more info is needed - I appreciate any and all help with this!

  • how do I zoom to normal text size in vs2008?

    - by gerryLowry
    I can not find any help on this issue in vs2008 help, Google, or SO. Scenario: I'm looking at a source file in vs2008 SP1; Windows 2003 Server SP2 Standard Edition, 1280x1024. The irrelevant name of this file is index.aspx. What is relevant is that the file has only 65 lines of code. The print is unreadably small--less than 4 point. It uses less than a third of the vs2008 text window vertically and less that a quarter of the vs2008 text window horizontally. It's not just index.aspx; e.g. another file with 142 lines only fills about 3/4 of the vs2008 text window vertically and less that a quarter of the vs2008 text window horizontally. Possible cause: Probably, but not certainly, I found the equivalent of zoom in/zoom out such as one finds in products like Microsoft Word. However, I've explored many vs2008 toolbars and other customization options and unfortunately I can not find out how to get myself out of this mess. Window, Reset Window Layout has no effect on the text size; my tiny text size did not change. QUESTION: how do I zoom vs2008 text size in and out and back to normal size? Thank you. Regards ~~ Gerry (Lowry)

  • Entity Framework 4.0 POCO Classes and Data Services

    If you've flipped on the POCO (Plain Ol' CLR Objects) code generation T4 templates for Entity Framework to enable testing or just 'cuz you like the code better, you might find that you lack the ability to expose that same model via Data Services as OData (Open Data). If you surf to the feed, you'll likely see something like this: The XML page cannot be displayed Cannot view XML input using XSL style sheet.

  • How can I automatically encode a folder of wmv files to flv?

    - by Oren
    I have a folder in which .wmvs are saved after they are finished recording. I would like to set up a script which encodes all of the files in this folder into .flvs with the appropriate size, frame rate, etc and then moves them to another folder. I have been looking for a command line .wmv to .flv converter to do this without much success. Has someone automatically encoded .wmvs to .flvs before that can point me in the right direction?

    I am sure all coding pundits here will have one (or multiple) ways of spending some time-off between hectic coding sessions just to relax. Would love to hear from you all as I am a newbie and want to take little breaks (non-physical) from coding and do things which actually help me focus again. Thanks.
