  • Rails request forgery protection settings

    - by Vitaly
    Hey, please help a newbie in Rails :) I have protect_from_forgery call (which is given by default) with no attributes in my ApplicationController class. Basically here's the code: class ApplicationController < ActionController::Base helper :all # include all helpers, all the time protect_from_forgery helper_method :current_user_session, :current_user filter_parameter_logging :password, :password_confirmation What I assume it should do is: it should prevent any POST requests without correct authenticity_token. But when I send post request with jQuery like the one below, it works fine (there's update statement that is executed in the database)! $.post($(this).attr("href"), { _method: "PUT", data: { test: true } }); I see in console that there's no authenticity_token among sent parameters, but request is still considered valid. Why is that?

  • Large number array compression

    - by gatapia
    Hi All, I've got a javascript application that sends a large amount of numerical data down the wire. This data is then stored in a database. I am having size issues (too much bandwidth, database getting too big). I am now ready to sacrifice some performance for compression. I was thinking of implementing a base 62 number.toString(62) and parseInt(compressed, 62). This would certainly reduce the size of the data but before I go ahead and do this I thought I would put it to the folks here as I know there must be some outside the box solution I have not considered. The basic specs are: - Compress large number arrays into strings for JSONP transfer (So I think UTF is out) - Be relatively fast, look I'm not expecting same performance as I have now but I also don't want gzip compression either. Any ideas would be greatly appreciated. Thanks Guido Tapia

  • 3rd Party Document Management Service

    - by Element
    I am developing an asp.net application that requires users to upload/view various documents. Rather then reinvent the wheel I was thinking about using a 3rd party service like Scribd to handle these documents and integrate it into my app via their API; I really like their ipaper viewer too. My concern is some of these documents will be sensitive data. Even though Scribd's FAQ says they are equipped to handle sensitive information, I am a little hesitant to trust an unpaid service that lacks an SLA. Has anyone used Scribd successfully for a similar task? Or can anyone recommend a better document management service?

  • Handling User Authentication in C#.NET?

    - by Daniel
    I am new to .NET, and don't have much experience in programming. What is the standard way of handling user authentication in .NET in the following situation? 1.In Process A, User inputs ID/Password 2.Process A sends the ID/Password to Process B over a nonsecure public channel. 3.Process B authenticates the user with the recieved ID/Password what are some of the standard cryptographic algorithms I can use in above model? The users(customers that bought my company's software) will be running the software(Process A) locally in their computer(connected to internet). I need to authenticate the users so that only registered users can run the program. Thank You!

  • How to kill msvsmon.exe when finished remote debugging?

    - by dferraro
    Hi, We are a .NET LOB shop using MS CRM as our CRM platform. To this end, we many times a day during development phases are using remote debugging due to 2 connection limit to the server. We are able to setup remote debugging without logging onto the machine by using PsExec. This works great - but how the heck do we kill the remote debugger for that user, once we are finished debugging? In fact, not even sure how to kill the remote debugger in general, even when manually opening it... without remoting into server and using task manager, or keeping the server open and doing File-Exit on the debugger. Any advice?

  • Education After High School

    - by Travis O.
    I know this isn't specifically a programming question, but please bear with me. I'm currently a high-school junior. I have no idea what to look for in a college: what degree, what school, etc. I've searched all around the internet but can't really find anything that relevant. I know I need a degree, but I don't know which or what to specialize in. My grades are good and I am in the top 15 percent of my class. I scored about a 1800 on the SAT and have not yet taken the ACT. I'd like to go to a 4 year school that doesn't cost too much. What do I need to be looking for and what is important to colleges accepting CS students and the business after college?

  • Datacontracts property getter running twice

    - by user321426
    I have a set of data contracts that act as wrappers to base classes that we wish to expose. A quick example is: [DataMember] public List<decimal> Points { get { return sourceObject.ListPoints(); } private set{} } We have some other properties that we have to massage the data first (we are converting object graphs and need to guard against circular references). The issue that we are seeing is that this getter will fire twice, once within the service operation, then again during serialization. This is causing two problems: We manually add to collections, since this is running twice the collections are filled with dupes. If an exception is thrown during the second run, it happens outside of the try/catch in the operation, and does not throw a fault. The service throws a cryptic timeout message, and the only way to see the error is via WCF trace logs.

  • What technologies should I focus on to work as a developer in Japan?

    - by Atomiton
    I'm thinking of one day moving to Japan and I was wondering if anyone here has any experience working there. I'm curious as to what languages/technology are popular there for web development and software development. I have heard Ruby is/was strong there due to its founder being Japanese. What would you recommend someone focus on if they wanted to work as a developer in Japan? I have heard Microsoft has a strong base in Japan, but my guess is that whatever platform has supported unicode or Shift-JIS the best would be the strongest.

  • How to improve my Python regex syntax?

    - by FarmBoy
    I very new to Python, and fairly new to regex. (I have no Perl experience.) I am able to use regular expressions in a way that works, but I'm not sure that my code is particularly Pythonic or consise. For example, If I wanted to read in a text file and print out text that appears directly between the words 'foo' and 'bar' in each line (presuming this occurred one or zero times a line) I would write the following: fileList = open(inFile, 'r') pattern = re.compile(r'(foo)(.*)(bar)') for line in fileList: result = pattern.search(line) if (result != None): print result.groups()[1] Is there a better way? The if is necessary to avoid calling groups() on None. But I suspect there is a more concise way to obtain the matching String when there is one, without throwing errors when there isn't. I'm not hoping for Perl-like unreadability. I just want to accomplish this common task in the commonest and simplest way.

  • Ruby types of collections in ActiveRecord

    - by kmorris511
    If I have an object with a collection of child objects in ActiveRecord, i.e. class Foo < ActiveRecord::Base has_many :bars, ... end and I attempt to run Array's find method against that collection: foo_instance.bars.find { ... } I receive: ActiveRecord::RecordNotFound: Couldn't find Bar without an ID I assume this is because ActiveRecord has hijacked the find method for its own purposes. Now, I can use detect and everything is fine. However to satisfy my own curiousity, I attempted to use metaprogramming to explicitly steal the find method back for one run: unbound_method = [].method('find').unbind unbound_method.bind(foo_instance.bars).call { ... } and I receive this error: TypeError: bind argument must be an instance of Array so clearly Ruby doesn't think foo_instance.bars is an Array and yet: foo_instance.bars.instance_of?(Array) -> true Can anybody help me with an explanation of this and of a way to get around it with metaprogramming?

  • Serializing Python bytestrings to JSON, preserving ordinal character values

    - by Doctor J
    I have some binary data produced as base-256 bytestrings in Python (2.x). I need to read these into JavaScript, preserving the ordinal value of each byte (char) in the string. If you'll allow me to mix languages, I want to encode a string s in Python such that ord(s[i]) == s.charCodeAt(i) after I've read it back into JavaScript. The cleanest way to do this seems to be to serialize my Python strings to JSON. However, json.dump doesn't like my bytestrings, despite fiddling with the ensure_ascii and encoding parameters. Is there a way to encode bytestrings to Unicode strings that preserves ordinal character values? Otherwise I think I need to encode the characters above the ASCII range into JSON-style \u1234 escapes; but a codec like this does not seem to be among Python's codecs. Is there an easy way to serialize Python bytestrings to JSON, preserving char values, or do I need to write my own encoder?

  • How can a Delphi TForm / TPersistent object calculate its own construction and deserialization time?

    - by mjustin
    For performance tests I need a way to measure the time needed for a form to load its definition from the DFM. All existing forms inherit a custom form class. To capture the current time, this base class needs overriden methods as "extension points": start of the deserialization process after the deserialization (can be implemented by overriding the Loaded procedure) the moment just before the execution of the OnFormCreate event So the log for TMyForm.Create(nil) could look like: - 00.000 instance created - 00.010 before deserialization - 01.823 after deserialization - 02.340 before OnFormCreate Which TObject (or TComponent) methods are best suited? Maybe there are other extension points in the form creation process, please feel free to make suggestions. Background: for some of our app forms which have a very basic structure (with some PageControls and QuantumGrids) I realized that it is not database access and other stuff in OnFormShow but the construction which took most of the time (around 2 seconds) which makes me wonder where this time is spent. As a reference object I will also build a mock form which has a similar structure but no code or datamodule connections and measure its creation time.

  • C# dictionary uniqueness for sibling classes using IEquatable<T>

    - by anthony
    I would like to store insances of two classes in a dictionary structure and use IEquatable to determine uniqueness of these instances. Both of these classes share an (abstract) base class. Consider the following classes: abstract class Foo { ... } class SubFoo1 : Foo { ... } class SubFoo2 : Foo { ... } The dictionary will be delcared: Dictionary<Foo, Bar> Which classes should be declared as IEquatable? And what should the generic type T be for those declarations? Is this even possible?

  • Entity Framework Model with inheritance and RIA Services

    - by TimothyP
    Hi, We have an entity framework model with has some inheritance in it. The following example is not the actuall model, but just to make my point... Let's say Base class: Person Child classes: Employee, Customer The database has been generated, the DomainService has been created and we can get to the data: lstCustomers.ItemsSource = context.Persons; EntityQuery<Person> query = context.GetPeopleQuery().Take(4); context.Load(query); But how can I modify the query to only return Customers ?

  • setDelegate:self, how does it work?

    - by fuzzygoat
    I have a query regarding how delegates work. My understanding was that delegates take responsibility for doing certain tasks on behalf of another object. locationManager = [[CLLocationManager alloc] init]; [locationManager setDelegate:self]; [locationManager setDistanceFilter:kCLDistanceFilterNone]; [locationManager setDesiredAccuracy:kCLLocationAccuracyBest]; [locationManager startUpdatingLocation]; Am I right in thinking that in the example code above that the instance of CLLocationManager is created on a new thread so that it can get on with trying to find the location information it needs. When it completes its task (or encounters an error) it calls-back using the appropriate methods located in self e.g. locationManager:didUpdateToLocation:fromLocation: Essentially locationManager sends messages to self (which conforms to the correct delegate protocol) when things happen cheers gary

  • How do I get Nant to use the 4.0 compiler to target .Net 3.5

    - by Rory Becker
    Yes I know that sounds a little bit crazy, but I've got .Net 3.5 deployed in the field and I'd like to use the new 4.0 compiler to target it. There are several new syntactic sugar features in the latest versions of Vb.Net and C# which I would like to use,but I am unable (just yet) to enforce a new version of the .Net framework and CLR on my client base. Before the nay sayers jump in with both feet... I have just successfully used Studio 2010 to compile a 3.5 targeted app which used VB.Net auto properties (A new feature in VB.Net 10) so I know the compilers are capable somehow. So back to my question.... How do I convince Nant to use the 4.0 compiler, but to target .Net 3.5 (CLR 2.0) Update: I am using the csc and vbc tasks and not the Solution task. although I'd settle for an answer on how to do this direct with the compilers at this point.

  • .NET Active Directory Password Expiration on Windows 2008

    - by Brent Pabst
    Searched SO and Everywhere else, including the .net developers guide to directory services programming book - no luck. I am trying to create a simple password reset web page that allows the user to change their password. The change password portion of the code is working fine. For the users I would also like to display when their current password will expire next. Using the sample code from the book mentioned above I was able to get all of the code setup however, the attribute that is returned is always equal to Long.MinValue and hence cannot be inverted to a positive number, plus this means it did not find the proper domain setting. Does anyone have sample code or references for getting the password expiration in a Windows 2008 or R2 domain environment where password policies can be different for each user?

  • Technologies used in Remote Administration applications(not RD)

    - by Michael
    I want to know what kind of technologies are used nowadays as underlying screen capture engine for remote administration software like VNC pcAnywhere TeamViewer RAC Remote Administrator etc.. The programming language is not so important as just to know whether a driver needs to be developed which is polling video memory 30 times per second or there are any com objects built in the Windows kernel to help doing this? I'm not interested in 3rd party components for doing this. Do I have to use DirectX facilities? Just want some start point to develop my own screen stream capture engine, which will be less CPU hog.

  • Is there a COM object that just implements IUnknown I can use?

    - by Matt
    For an asynchronous Windows API, I can provide an IUnknown state parameter to associate calls to the API with calls from the callback. It's my understanding that COM guarantees that two IUnknown pointers to the same object will be of the same value. Thus, if I only want to associate API calls with callbacks, IUnknown should be all I need, by comparing the values of the pointers. Is there a stock implementation of IUnknown I can use? Of course it would be trivial to implement myself, but for such a base component of COM, I'm wondering if Windows or ATL provides one I should use instead. Thanks, --Matt

  • Racket list in struct

    - by Tim
    I just started programming with Racket and now I have the following problem. I have a struct with a list and I have to add up all prices in the list. (define-struct item (name category price)) (define some-items (list (make-item "Book1" 'Book 40.97) (make-item "Book2" 'Book 5.99) (make-item "Book3" 'Book 20.60) (make-item "Item" 'KitchenAccessory 2669.90))) I know that I can return the price with: (item-price (first some-items)) or (item-price (car some-items)). The problem is, that I dont know how I can add up all Items prices with this. Answer to Óscar López: May i filled the blanks not correctly, but Racket mark the code black when I press start and don't return anything. (define (add-prices items) (if (null? items) (+ 0 items) ; Here I don't really know what to write for a 0. ; I tried differnt thnigs like null and this version. (+ (item-price (first some-items)) (add-prices (item-price (rest some-items))))))
