  • paperclip private files

    - by Dmitriy Likhten
    Is there a way to make paperclip attachments private? As in only where I explicitly want a user to be able to access a file, can the user access the file. Obviously the file can't be in a public directory, but how do I get paperclip to check the user's access rights when trying to access that file to begin with?

  • Heroku powered private restricted beta

    - by Ben Sand
    I'd like to run an app in a restricted private beta on heroku. We're changing the app regularly and haven't done a security audit. To stop anyone exploiting stuff, we'd like to lock down the whole site, so you need a password to access anything. Ideally similar to using .htaccess and .htpasswd files to lock an entire site on an Apache server. Is there a simple one shot way to do this for a heroku hosted app?

  • SerialVersionUID with "private static final long" still gets InvalidClassException

    - by Buggieboy
    I have compiled and jarred the various projects in my Java application, generating serialVersionUIDs automatically through Eclipse for all my classes derived from Serializable. I read the answers to this question, and verified that serialVersionUids are all private static final long. Nevertheless, I get an error like this when I try to run: java.io.InvalidClassException: com.acme.product.Widget; local class incompatible: stream classdesc serialVersionUID = 5226096973188250357, local class serialVersionUID = -5432967318654384362 What am I missing?

  • SSH is looking in the wrong place for the public/private key pair on Windows

    - by Michael Morisy
    I'm trying to configure GIT on my Windows XP machine, but SSH keeps creating and looking for the public/private key pair in non-sensical places, e.g. /.ssh/id_rsa Is there a configuration file in the GIT Installation for Windows where I can switch this to my home directory, or another user defined place? By default, it offers to create new key pairs at //.ssh/id_rsa but that gives me the error "Could not create directory '//.ssh'." And when I'm able to find a directory I can create it in, GIT won't look there.

  • Saving private data

    - by rajatgoel
    Hi, Can anybody detail some approach on how to save private data in social websites like facebook, etc. They cant save all the updates and friends list in clear text format because of privacy issues. So how do they actually save it? Hashing all the data with user password so that only a valid session view it is one possibility. But I think there are some problem with this approach and there must be some better solution.

  • Private heap or manage memory self

    - by Max
    Hello all, I know we could take some advantages from creating private heap of Windows especially for frequently allocated and de-allocated small chunks. But I think the normal approach is to allocate a large memory from default heap and manage the allocations and de-allocations ourselves. My question is which way is advantages and disadvantage between those two ways? Thanks, Max

  • C# BestPractice: Private var and Public Getter/Setter or Public Var

    - by Desiny
    What are the advantages and differences between the below two coding styles... public void HelloWorld () { private string _hello; public string Hello { get { return _hello; } set { _hello = value; } } } or public void HelloWorld () { public string Hello { get; set; } } My preference is for short simple code, but interested to hear opinions as I see many developers who insist on the long route.

  • When not to use a private field

    - by coffeeaddict
    When should it be considered dangerous to use a private field all over the place in the methods of your class? I mostly just create the variable and set it to a default value like null. Then in my methods reference it and set it to an instance of that object type from the methods. I don't know if my question makes sense but let me know if it doesn't and I'll clarify.

  • Multiple certs with one private key on apache?

    - by tenbatsu
    Really fundamental question here, but nothing a quick google search is lending itself to. Do I need to generate a separate private key for each cert I use in apache? Server details: % /usr/sbin/httpd -v Server version: Apache/2.2.8 (Unix) Server built: Jan 24 2008 10:44:19 % uname -a Linux *.com 2.6.23.15-80.fc7 #1 SMP Sun Feb 10 17:29:10 EST 2008 i686 i686 i386 GNU/Linux % cat /proc/versionversion 2.6.23.15-80.fc7 ([email protected]) (gcc version 4.1.2 20070925 (Red Hat 4.1.2-27)) #1 SMP Sun Feb 10 17:29:10 EST 2008

  • Working with multiple GIT severs

    - by th3flyboy
    Hello, I have a question. Is it possible to set up a system so that you have a private GIT server that you host, which automatically syncs with a remote one, hosted by a site like Sourceforge, and then you can commit your local to the private GIT server, and then when you have to merge the changes from your private wip branches that are on your private GIT over to the master/branch/tag from the public GIT, and then push the change to the public GIT? I ask this because I have a lot of personal work I would like to get working before putting it up for the public to see, and I'm shifting between several computers/operating systems in the process. If this is not possible in standard GIT, are there any other options that would allow me to do this? Thanks, Peter

  • Why does Farseer 2.x store temporaries as members and not on the stack? (.NET)

    - by Andrew Russell
    UPDATE: This question refers to Farseer 2.x. The newer 3.x doesn't seem to do this. I'm using Farseer Physics Engine quite extensively at the moment, and I've noticed that it seems to store a lot of temporary value types as members of the class, and not on the stack as one might expect. Here is an example from the Body class: private Vector2 _worldPositionTemp = Vector2.Zero; private Matrix _bodyMatrixTemp = Matrix.Identity; private Matrix _rotationMatrixTemp = Matrix.Identity; private Matrix _translationMatrixTemp = Matrix.Identity; public void GetBodyMatrix(out Matrix bodyMatrix) { Matrix.CreateTranslation(position.X, position.Y, 0, out _translationMatrixTemp); Matrix.CreateRotationZ(rotation, out _rotationMatrixTemp); Matrix.Multiply(ref _rotationMatrixTemp, ref _translationMatrixTemp, out bodyMatrix); } public Vector2 GetWorldPosition(Vector2 localPosition) { GetBodyMatrix(out _bodyMatrixTemp); Vector2.Transform(ref localPosition, ref _bodyMatrixTemp, out _worldPositionTemp); return _worldPositionTemp; } It looks like its a by-hand performance optimisation. But I don't see how this could possibly help performance? (If anything I think it would hurt by making objects much larger).
