• Do you know of a bleeding-edge HTML5 leveraging, legacy-ignoring JavaScript framework?

  - by Ivan

  What's the best framework (sort of jquery, extjs, etc like) to use if I'd like to intensively use all the freshest technologies of the HTML5 stack provided by modern browsers (Firefox 3.6+ (Minefield especially), Safari 4+, Chrome 4+) and have absolutely no need to support any legacy browsers (incl. no need in IE support at all, no need in Firefox prior to 3.5, etc.)? I'd like to get all the newest available goodness without having (even abstracted by a library layer) a line of code meant just fore legacy compatibility and keeping no legacy-induced things in mind. To soften the filter, taking very humble hope of such an ideally fresh framework to exist, the least (the maximum level of legacy support) I'd like to agree is not supporting IE versions older than IE8, or better just not supporting IE at all.

• Deserialization on client side in Domain Service

  - by ankit

  I have 2 classes: Person and Contact. Person class has a property named ContactNumber which returns the Contact type, and this property is marked as a DataMember for serialization. I have marked Contact type as a DataContract. On the client side I am able to get the values, but when I try to insert a value and then do submit, I get the following exception: Failed to deserialize change-set. Failed to convert value of type 'Dictionary`2' to type 'Contact' Stack Trace is: at System.Web.Ria.DataServiceSubmitRequest.GetChangeSet(DomainService domainService) at System.Web.Ria.DataServiceSubmitRequest.Invoke(DomainService domainService) at System.Web.Ria.DataService.System.Web.IHttpHandler.ProcessRequest(HttpContext context) Can anyone give me the solution ?

• Manipulating the address of a variable to store a smaller type?

  - by Sidnicious

  This is what I get for pampering myself with high-level programming languages. I have a function which writes a 32-bit value to a buffer, and a uint64_t on the stack. Is the following code a sane way to store it? uint64_t size = 0; // ... getBytes((uint32_t*)&size+0x1); I'm assuming that this would be the canonical, safe style: uint64_t size = 0; // ... uint32_t smallSize; getBytes(&smallSize); size = smallSize;

• Catch and Show an error from a WCF service call in javascript.

  - by cw

  Hello, I'm calling a WCF service through javascript and right now it's not showing any errors that might occur on the service side to the user. I have the code below and am looking for a better way to inform the user an error has occured, including the call stack and error message if possible. The service itself throws a FaultException if an error has occured. However, I want to catch that error in the javascript call and show it to the user. Here is the js code to call the service function Save() { var saveInfo = $("._saveInfo").val() app.namspace.interfacetoservice.Save( saveInfo, function(results) { if (results == true) { window.close(); } else { alert("error saving"); } } ); } Thanks for the help!

• StringConverter with StandardValuesSupported and Autocompletion

  - by Marqus

  I want to develop a StringConverter with standard values, which after attaching it to a PropertyGrid will act like comboBox with autocompletion. The example below will give me a comboBox, but without the autocompletion - user have to expand it and choose manually one of the items. Is there a way to allow user to type the beginning of one of the options, so the combobox will automatically select the matching one? public class ConverterSample : System.ComponentModel.StringConverter { public override bool GetStandardValuesSupported(ITypeDescriptorContext context) { //true means show a combobox return true; } public override bool GetStandardValuesExclusive(ITypeDescriptorContext context) { return false; } public override TypeConverter.StandardValuesCollection GetStandardValues(ITypeDescriptorContext context) { return new StandardValuesCollection(new List<string>(){"Stack", "overflow", "rules"); } List returned by GetStandardValues has to be dynamic, so I can't use any enum there. I took above example from: http://www.codeproject.com/KB/cpp/dropdownproperties.aspx

• My Ruby Code: How can I improve? (Java to Ruby guy)

  - by steve

  Greetings, I get the feeling that I'm using ruby in an ugly way and possibly missing out on tonnes of useful features. I was wondering if anyone could point out a cleaner better way to write my code which is pasted here. The code itself simply scrapes some data from yelp and processes it into a json format. The reason I'm not using hash.to_json is because it throws some sort of stack error which I can only assume is due to the hash being too large (It's not particularly large). Response object = a hash text = the output which saves to file Anyways guidance appreciated. def mineLocation client = Yelp::Client.new request = Yelp::Review::Request::GeoPoint.new(:latitude=>13.3125,:longitude => -6.2468,:yws_id => 'nicetry') response = client.search(request) response['businesses'].length.times do |businessEntry| text ="" response['businesses'][businessEntry].each { |key, value| if value.class == Array value.length.times { |arrayEntry| text+= "\"#{key}\":[" value[arrayEntry].each { |arrayKey,arrayValue| text+= "{\"#{arrayKey}\":\"#{arrayValue}\"}," } text+="]" } else text+="\"#{arrayKey}\":\"#{arrayValue}\"," end } end end

• Types in Bytecode

  - by HH

  Hey everyone, I've been working for some time on (Java) Bytecode, however, it had never occurred to me to ask why are some instructions typed? I understand that in an ADD operation, we need to distinguish between an integer addition and a FP addition (that's why we have IADD and FADD). However, why do we need to distinguish between ISTORE and FSTORE? They both involve the exact same operation, which is moving 32 bits from the stack to a local variable position? The only answer I can think of is for type-safety, to prevent this: (ILOAD, ILOAD, FADD). However, I believe that type-safety is already enforced at the Java language level. OK, the Class file format is not directly coupled with Java, so is this a way to enforce type-safety for languages that do not support it? Any thought? Thank you.

  I'm trying to follow this documentation on Symfony : http://symfony.com/doc/current/book/forms.html ok so here is my thing, I've externalised my form and created a specific form class for handling the process and being able to reuse it. So what happen when I submit the form, whatever the info are okay or not for my class, I get this fatal Error : Fatal error: Call to a member function setAttribute() on a non-object in C:\Program Files (x86)\wamp\www\QNetworks\vendor\symfony\src\Symfony\Component\Form\Extension\Core\DataTransformer\NumberToLocalizedStringTransformer.php on line 130 Call Stack I'm running with php 5.3.9 and my intl extension is installed and activated BUT when I run the app/check.php command I see : [[WARNING]] Checking that the intl extension is available: FAILED * Install and enable the intl extension (used for validators) * So I don't understand what the problem with this extension. Should I reinstall it ?

• css anchor div to foot of page

  - by foxed

  I may bounce my head off the wall shortly, I can't believe that something as stupid as this has utterly defeated me ... therefore I turn to you, Stack Overflow ... for guidance and enlightenment. Problem: Sit div at foot of page, 100% width, outside of any sort of wrapper. Proposed Solution: http://ryanfait.com/sticky-footer/ Implementation with content: http://www.weleasewodewick.com/redesign/index_content.html Implementation with no content: http://www.weleasewodewick.com/redesign/index.html with content - Good, works nicely no content = bad, footer sits exactly height of footer below the viewport. I really would appreciate your input into this, it's completely vexed me for the past hour. I wholly expect some form of ridicule :) Thanks! Foxed

• How do I prevent an ASP.NET MVC deployment on IIS 6.0, using wildcard mapping, from attempting to ha

  - by Rob

  As noted by the title, what is the best way to configure an IIS 6.0 deployment of an ASP.NET MVC application such that connections to hidden shares are ignored? The application in question is using wildcard mapping to allow for clean URLs since we are planning on upgrading to IIS 7.0 in the near future and we are also handling the caching and compression issues with a custom library so we would like to avoid turning wildcard mapping off unless absolutely necessary. Below is a one of the errors from the application to give you an example of what we are seeing. -------------------------------------------------------------------------------- System.Web.HttpException -------------------------------------------------------------------------------- Time Stamp - 03 Mar 2010, 08:11:44 Path - N/A, Internal Server Operation Message - The controller for path '/C$' could not be found or it does not implement IController.

• Tag-like autocompletion and caret/cursor movement in contenteditable elements.

  - by jimeh

  I'm working on a jQuery plugin that will allow you to do @username style tags, like Facebook does in their status update input box. My problem is, that even after hours of researching and experimenting, it seems REALLY hard to simply move the caret. I've managed to inject the <a> tag with someone's name, but placing the caret after it seems like rocket science, specially if it's supposed work in all browsers. And I haven't even looked into replacing the typed @username text with the tag yet, rather than just injecting it as I'm doing right now... lol There's a ton of questions about working with contenteditable here on Stack Overflow, and I think I've read all of them, but they don't really cover properly what I need. So any more information anyone can provide would be great :)

• Debugging kernel hang

  - by l.thee.a

  I am trying to run an app which is using a kernel mode driver. System locks up every hour and the only way to recover it is a hard reset. Sysrq stops responding, telnet sessions hang and there are no error messages of any kind. Unfortunately the board does not have ejtag support. I have been trying to isolate it functionally, but this is like looking for a needle in a hay stack. Any suggestions? PS: This is a mips linux system (2.6.31).

• c++ warning: address of local variable

  - by chnet

  int * ref () { int tmp = 100; return &tmp; } int main () { int * a = ref(); cout << *a << endl; } I know the function ref () is allocated stack space. It will get destroyed as soon as the function exits. So the complier will give warning information. But my question is why the returning result is still correct.

• Finding Errant Output to System.out in Large Java Program

  - by SvrGuy

  Hi, We have a large java code base [~1 M Lines]. Buried (somewhere) in the code base is some old debug output to System.out that we want to remove (its cluttering things up). The problem is: out code base is so large that we can't easily find where the output is coming from. What we want is a way to see where System.out.println is getting called from (like a stack trace from an exception or some such). Its not suitable to debugging -- the errant output is coming from some errant thread somewhere etc. Any ideas on how to track the source of this errant output down? PS: 99.99% of calls to System.out are legit, and we have thousands of them, so simply searching the code base for System.out calls is not a solution!

• Any AOP support library for Python ?

  - by edomaur

  I am trying to use some AOP in my Python programming, but I do not have any experience of the various libs that exists. So my question is : What AOP support exists for Python, and what are the advantages of the differents libraries between them ? Edit : I've found some, but I don't know how they compare : Aspyct Lightweight AOP for Python Edit2 : In which context will I use this ? I have two applications, written in Python, which have typically methods which compute taxes and other money things. I'd like to be able to write a "skeleton" of a functionnality, and customize it at runtime, for example changing the way local taxes are applied (by country, or state, or city, etc.) without having to overload the full stack.

• Can I prevent Flash's Input Events from stacking up when my framerate low?

  - by Matt W

  My Flash game targets 24 fps, but slows to 10 on slower machines. This is fine, except Flash decides to throttle the queue of incoming MouseEvent and KeyboardEvents, and they stack up and the Events fall behind. Way behind. It's so bad that, at 10 fps, if I spam the Mouse and Keyboard for a few seconds not much happens, then, after I stop, the game seems to play itself for the next 5 seconds as the Events trickle in. Spooky, I know. Does anyone know a way around this? I basically need to say to Flash, "I know you think we're falling behind, but throttling the input events won't help. Give them to me as soon as you get them, please."

• Python module seeing a full list as empty in another module

  - by Nick

  I'm working on a pygame project and have the main engine layed out. The problem is I hit a bug that I just can not seem to figure out. What happens is one module can't read a variable from another module. It's not that the variable can't be read, it just sees an empty list instead of what it really is. Instead of posting the entire source code I reproduced the bug in two small snippets that hopefully a skillful python-ist can interpret in his\her head. Code: main.py (This is the file that gets run) import screen screens = [] #A stack for all the game screens def current_screen(): #return a reference to the current screen return screens[-1] def play(): print'play called' current_screen().update() if __name__=='__main__': screens.append(screen.Screen()) play() screen.py import main class Screen: def __init__(self): print'screen made' def update(self): print main.screens #Should have a reference to itself in there Thanks!

• How many parameters in C# method are acceptable?

  - by Valentin Heinitz

  I am new to C# and have to maintain a C# Application. Now I'v found a method vaving 32 Parameters (not auto-generated code). From C/C++ I remember the rule of thumb "4 Parameters". It may be an old-fashioned rule rooting back to old 0x86 compilers, where 4 Parameters could be accomodated in registers (fast) or on stack otherwise. I am not concerning about performance, but I do have a feeling, that 32 parameters per functions are not easy to maintain even in C#. Or am I completly not up to date? What is the rule of thumb for C#? Thank you for any hint!

• Corrupted image if variable is not static

  - by Jaka Jancar

  I'm doing the following: static GLfloat vertices[3][3] = { {0.0, 1.0, 0.0}, {1.0, 0.0, 0.0}, {-1.0, 0.0, 0.0} }; glColor4ub(255, 0, 0, 255); glEnableClientState(GL_VERTEX_ARRAY); glVertexPointer(3, GL_FLOAT, 0, vertices); glDrawArrays(GL_TRIANGLES, 0, 9); glDisableClientState(GL_VERTEX_ARRAY); This works ok: However, if I remove static from vertices and therefore re-create the data on the stack on each rendering, I get the following: This happens both on the simulator and on the device. Should I be keeping the variables around after I call glDrawArrays?

• Considering getting into reverse engineering/disassembly

  - by Zombies

  Assuming a decent understanding of assembly on common CPU architectures (eg: x86), how can one explore a potential path (career, fun and profit, etc) into the field of reverse engineering? There is so little educational guides out there so it is difficult to understand what potential uses this has today (eg: is searching for buffer overflow exploits still common, or do stack monitoring programs make this obselete?). I am not looking for any step by step program, just some relevant information such as tips on how to efficiently find a specific area of a program. Basic things in the trade. As well as what it is currently being used for today. So to recap, what current uses does reverse engineering yield today? And how can one find some basic information on how to learn the trade (again it doesn't have to be step-by-step, just anything which can through a clue would be helpful).

• Avoiding string copying in Lua

  - by Matt Sheppard

  Say I have a C program which wants to call a very simple Lua function with two strings (let's say two comma separated lists, returning true if the lists intersect at all, false if not). The obvious way to do this is to push them onto the stack with lua_pushstring, which works fine, however, from the doc it looks like lua_pushstring but makes a copy of the string for Lua to work with. That means that to cross over to the Lua function is going to require two string copies which I could avoid by rewriting the Lua function in C. Is there any way to arrange things so that the existing C strings could be reused on the Lua side for the sake of performance (or would the strcpy cost pale into insignificance anyway)? From my investigation so far (my first couple of hours looking seriously at Lua), lite userdata seems like the sort of thing I want, but in the form of a string.
