  • jquery upgrade breaking existing code

    - by Victor
    I have a following event handler which worked in jquery 1.3.2 but stopped working when we upgraded to 1.8.2, still fired but doesn't do anything $('input.maskedInput').focus(function () { $(this).mask("999-999-9999"); }).blur(function () { $(this).unmask(); var numbers = $(this).val().replace(/-/g, '').replace(/_/g, ''); $(this).val(numbers.toString()); }); What could be a problem?

  • Writing secure java code with RMI

    - by jtnire
    Hi Everyone, This may seem like a very broad question, but any help is appreciated. I have a client/server solution written in java which uses the Cajo project (which uses RMI). I just want to try and make my solution as secure as possible, given the sensitive data that will be transferred between server and client. So far, my ideas are to make all my classes "final" as well as throw a "non-serializable" exception for all my classes in the server (except for the object bound in the RMI registry, and any objects that actually do need to be transferred of course). Can anyone think of any other ideas? I know that someone could write a malicious client - this isn't hard to do as you can find out the remote object's API using reflection. However is there anything I can do to protect a malicious client access classes/objects within the server that they are not supposed to access? Many Thanks

  • Parsing/executing C# code in C++ (on Linux)?

    - by Stick it to THE MAN
    I want to be able to add scripting functionality to my application. One of the language bindings I am considering is C# (and possibly VB.Net). The challenge is this: My application is developed in C++ My application runs on Linux I am aware of Mono, but I dont know (as yet), what is required to allow my C++ appliaction (running on linux), to be scriptable with .Net languages. Is this feasible? Am I crazy for even thinking of doing this? If I'm not crazy, can anyone provide some guidelines on how to go about implementing this? Help, tips, ideas, suggestions anyone?

  • How to optimize this Python code?

    - by RandomVector
    def maxVote(nLabels): count = {} maxList = [] maxCount = 0 for nLabel in nLabels: if nLabel in count: count[nLabel] += 1 else: count[nLabel] = 1 #Check if the count is max if count[nLabel] > maxCount: maxCount = count[nLabel] maxList = [nLabel,] elif count[nLabel]==maxCount: maxList.append(nLabel) return random.choice(maxList) nLabels contains a list of integers. The above function returns the integer with highest frequency, if more than one have same frequency then a randomly selected integer from them is returned. E.g. maxVote([1,3,4,5,5,5,3,12,11]) is 5

  • MySQL optimised code for 2 tables?

    - by David19801

EDIT: id is username, integers in table2 is just integers. but have not built the tables yet, so can change if need to.

  • Return popupmenu selection in MATLAB using one line of code

    - by Doresoom
    I have a GUI which uses a selection from a popupmenu in another callback. Is there a way to return the selected value of the popupmenu in only one line without creating any temporary variables? I've tried several solutions, but I've only managed two lines with one temporary variable: Three lines: list=get(handles.popupmenu1,'String'); val=get(handles.popupmenu1,'Value'); str=list{val}; Two lines: temp=get(handles.popupmenu1,{'String','Value'}); str=temp{1}{temp{2}}; Can anyone shave it down to one? PS, It's a dynamic menu, so I can't just use get(handles.popupmenu1,'Value') and ignore the string component altogether.)

  • Django throws 404 at generic views

    - by x0rg
    I'm trying to get the generic views for a date-based archive working in django. I defined the urls as described in a tutorial, but django returns a 404 error whenever I want to access an url with a variable (such as month or year) in it. It don't even produces a TemplateDoesNotExist-execption. Normal urls without variables work fine. Here's my urlconf: from django.conf.urls.defaults import * from zurichlive.zhl.models import Event info_dict = { 'queryset': Event.objects.all(), 'date_field': 'date', 'allow_future': 'True', } urlpatterns += patterns('django.views.generic.date_based', (r'events/(?P<year>d{4})/(?P<month>[a-z]{3})/(?P<day>w{1,2})/(?P<slug>[-w]+)/$', 'object_detail', dict(info_dict, slug_field='slug',template_name='archive/detail.html')), (r'^events/(?P<year>d{4})/(?P<month>[a-z]{3})/(?P<day>w{1,2})/(?P<slug>[-w]+)/$', 'object_detail', dict(info_dict, template_name='archive/list.html')), (r'^events/(?P<year>d{4})/(?P<month>[a-z]{3})/(?P<day>w{1,2})/$','archive_day',dict(info_dict,template_name='archive/list.html')), (r'^events/(?P<year>d{4})/(?P<month>[a-z]{3})/$','archive_month', dict(info_dict, template_name='archive/list.html')), (r'^events/(?P<year>)/$','archive_year', dict(info_dict, template_name='archive/list.html')), (r'^events/$','archive_index', dict(info_dict, template_name='archive/list.html')), ) When I access /events/2010/may/12/this-is-a-slug I should get to the detail.html template, but instead I get a 404. What am I doing wrong?

  • Why might my Emacs use spaces instead of tabs?

    - by Fletcher Moore
    I am trying to diagnose this problem. TAB creates 4 spaces instead of a 4 col TAB like I want. But I don't think it should because C-h v indent-tabs-mode on the buffer in question says it is set to t. When I check my keybindings, TAB is set to c-indent-line-or-region. Does this function ignore my tabs-mode?

  • Invoking code both before and after WebControl.Render method

    - by Dirk
    I have a set of custom ASP.NET server controls, most of which derive from CompositeControl. I want to implement a uniform look for "required" fields across all control types by wrapping each control in a specific piece of HTML/CSS markup. For example: <div class="requiredInputContainer"> ...custom control markup... </div> I'd love to abstract this behavior in such a way as to avoid having to do something ugly like this in every custom control, present and future: public class MyServerControl : TextBox, IRequirableField { public IRequirableField.IsRequired {get;set;} protected override void Render(HtmlTextWriter writer){ RequiredFieldHelper.RenderBeginTag(this, writer) //render custom control markup RequiredFieldHelper.RenderEndTag(this, writer) } } public static class RequiredFieldHelper{ public static void RenderBeginTag(IRequirableField field, HtmlTextWriter writer){ //check field.IsRequired, render based on its values } public static void RenderEndTag(IRequirableField field, HtmlTextWriter writer){ //check field.IsRequired , render based on its values } } If I was deriving all of my custom controls from the same base class, I could conceivably use Template Method to enforce the before/after behavior;but I have several base classes and I'd rather not end up with really a convoluted class hierarchy anyway. It feels like I should be able to design something more elegant (i.e. adheres to DRY and OCP) by leveraging the functional aspects of C#, but I'm drawing a blank.

  • Using .dll methods to load data from file in C# code

    - by Espinas.iss
    I want to use in C# these methods: * int LibRaw::open_datastream(LibRaw_abstract_datastream *stream) * int LibRaw::open_file(const char *rawfile) * int LibRaw::open_buffer(void *buffer, size_t bufsize) * int LibRaw::unpack(void) * int LibRaw::unpack_thumb(void) that are stored in a libraw.dll. These functions one by one load data from file... I've been reading about P/Invoke but i'm not sure how to invoke them. Can anyone show me an example how to use all of these functions together in C# to load file (raw image stored in folder) or just how to PIvoke one of them. Thanx!

  • Code Interaction with Quartz Composition

    - by Alberto MQO
    Hi, i have a Quartz Composition with a Cube, and X/Y/Z rotation inputs are published. On Interface Builder i made a QCView and a QCPatchController with the previous Quartz Composition loaded. In QCView the Patch Controller is binded, and the rotation published ports are binded too to three NSSlider, so when i change the value of the NSSlider's then the cube rotates. All this works fine, but i want to change the rotation values of the cube from the App Delegate on XCode. I tried to change the value of the NSSliders with IBoulets pointing to them, but this change doesnt apply to the cube, like it does when i change the Sliders directly with my mouse. What should i instanciate and/or how to access and change this Input_Ports.value throught the CQPatchController? Thank you very much for reading, i really need help!

  • What do you do with GitHub repositories you no longer maintain?

    - by T. Stone
    What do you do with GitHub repositories you no longer maintain? For whatever reason a project is started with a GitHub repository and then sometime later it's abandoned Perhaps it was an experiment that didn't work out. Perhaps you replaced it with a commercial product. Or perhaps you found a similar project to what you were doing and joined their efforts instead. In the time your repository was alive, it attracted watchers and a few forks. What do you do with it at that point? Is there a way to nicely indicate that repository is no longer maintained and to either check out the forks or a different project?

  • Dynamically generating high performance functions in clojure

    - by mikera
    I'm trying to use Clojure to dynamically generate functions that can be applied to large volumes of data - i.e. a requirement is that the functions be compiled to bytecode in order to execute fast, but their specification is not known until run time. e.g. suppose I specify functions with a simple DSL like: (def my-spec [:add [:multiply 2 :param0] 3]) I would like to create a function compile-spec such that: (compile-spec my-spec) Would return a compiled function of one parameter x that returns 2x+3. What is the best way to do this in Clojure?
