• Multiple file types in vim

  - by Chad

  When I am working on a PHP file for example the default filetype is php. This makes sense, however when that PHP file has HTML as well the filetype is still only php. For some plugins that means that I get the PHP functionality for that plugin, but miss out on the HTML functionality. A more specific situation where this happens is with my snippet plugin. I get php snippets and not html snippets when I am editing a php file. Possible solutions to this (which I obviously don't like, hence my posting this question) are: add a map to toggle between different filetypes when I am editing different sections of the file. update my php snippets file to include the html snippets as well (while this would work for the example above, it doesn't solve the fundamental problem). So, Is there a way to edit a file using multiple filetypes at the same time in vim?

• Authlogic Current User Question - hiding admin links...

  - by bgadoci

  I think I am missing something while using the Authlogic gem w/ Rails. To set the stage I have multiple users and each user can create posts and comments. Upon the display of a post or comment I would like to give the user who created them the option to edit or destroy. I am successfully using the following code to hide and show elements based on if a user is logged in or not but can't seem to find out how to only show these links to the actual user who created them...not any user that is logged in. <% if current_user %> <%= link_to 'Edit', edit_question_path(question) %> | <%= link_to 'Destroy', question, :confirm => 'Are you sure?', :method => :delete %> <% else %> <p>nothing to see here</p> <% end %> Here is the def of current_user located in the application controller in case I need to change something here. class ApplicationController < ActionController::Base helper :all # include all helpers, all the time protect_from_forgery # See ActionController::RequestForgeryProtection for details# helper_method :current_user private def current_user_session return @current_user_session if defined?(@current_user_session) @current_user_session = UserSession.find end def current_user return @current_user if defined?(@current_user) @current_user = current_user_session && current_user_session.record end end

• Prevent illegal behavior to the registered user

  - by Al Kush

  I am building a website in which this website will be focused on the publishing of novels. Every writers who publish their novels with us will get a royalty from us. And this royalty comes from the user or the reader who read the novel online in our website. When a user search for a novel and want to read that, they will click a link to the page which its content is that novel. The html page for each novels will have a session function that first will force them to login or register to make a payment such as with a credit-card or paypal before accessing that html page. My problem now is if the user has succesfully login and access the html page, I am afraid if the user will copy the content of the novel. Some disccussion out here How to Disable Copy Paste (Browser) have a solution to create it in Flash so that it can't be coppied-paste. But the I think, if the user who access it is a web developer like us they will try to find the path of the file from the link in the page source, and then they can steal it. For now I think it is enough I am explaining this. I hope anyone fully accept this problem (question) with a good idea to solve it.

• Should primitive types or non-primitive types be preferred in Java interfaces?

  - by Greg Mattes

  (I thought I once read something about this in a book, but now I'm not sure where to find it. If this question reminds you of some material that you've read, please post a reference!) What are the pros and the cons of primitives in interfaces? In other words, is one of these preferable to the other and why? Perhaps one is preferable to the other in certain contexts? public interface Foo { int getBar(); } or public interface Foo { Integer getBar(); } Similarly: public interface Boz { void someOperation(int parameter); } or public interface Boz { void someOperation(Integer parameter); } Obviously there's the issue of having to deal with nulls in the non-primitive case, but are there deeper concerns?

• How to automatically add user account *and* password with a Bash script

  - by ModernCarpentry

  I need to have the ability to create user accounts on my Linux ( Fedora 10 ) and automatically assign a password via a bash script ( or otherwise, if need be ). It's easy to create the user via Bash eg: [whoever@server ]# /usr/sbin/useradd newuser But is it possible to assign a password in Bash, something functionally similar to this (but automated): [whoever@server ]# passwd newuser Changing password for user testpass. New UNIX password: Retype new UNIX password: passwd: all authentication tokens updated successfully. [whoever@server ]#

• Set focus and carret position in textarea according to mouse position, as if user had clicked

  - by JeanHuguesRobert

  Once a page with a textarea is loaded, I want some textarea to have the focus immediatly if the mouse cursor is inside that textarea. This is the easy part because a onmousehover handler can set the focus. Now, how to I also set the position of the caret? I would like the caret to be where it would be if the user had clicked using the mouse to set the focus/caret. The basic use case is : User clicks on a link and waits (mouse barely moves) A page is delivered, it contains a big textarea only, full of text User types using keyboard Characters are inserted right below the mouse cursor Today the user has to wait until the caret is visible (at the top left of the textarea) and then click to move the caret before typing. Thanks!

• Extending User object in Django: User model inheritance or use UserProfile?

  - by Chris

  To extend the User object with custom fields, the Django docs recommend using UserProfiles. However, according to this answer to a question about this from a year or so back: extending django.contrib.auth.models.User also works better now -- ever since the refactoring of Django's inheritance code in the models API. And articles such as this lay out how to extend the User model with custom fields, together with the advantages (retrieving properties directly from the user object, rather than through the .get_profile()). So I was wondering whether there is any consensus on this issue, or reasons to use one or the other. Or even what the Django team currently think?

• ASP.NET: Custom MembershipProvider with a custom user table

  - by blahblah

  I've recently started tinkering with ASP.NET MVC, but this question should apply to classic ASP.NET as well. For what it's worth, I don't know very much about forms authentication and membership providers either. I'm trying to write my own MembershipProvider which will be connected to my own custom user table in my database. My user table contains all of the basic user information such as usernames, passwords, password salts, e-mail addresses and so on, but also information such as first name, last name and country of residence. As far as I understand, the standard way of doing this in ASP.NET is to create a user table without the extra information and then a "profile" table with the extra information. However, this doesn't sound very good to me, because whenever I need to access that extra information I would have to make one extra database query to get it. I read in the book "Pro ASP.NET 3.5 in C# 2008" that having a separate table for the profiles is not a very good idea if you need to access the profile table a lot and have many different pages in your website. Now for the problem at hand... As I said, I'm writing my own custom MembershipProvider subclass and it's going pretty well so far, but now I've come to realize that the CreateUser doesn't allow me to create users in the way I'd like. The method only takes a fixed number of arguments and first name, last name and country of residence are not part of them. So how would I create an entry for the new user in my custom table without this information at hand in CreateUser of my MembershipProvider?

• Launch User Control in a tab control dynamically

  - by Redburn

  I have a custom built menu system in which I would like to load user controls from another project into a tab control on my main project (menu control) User control Project : foobar Menu system Project : Menu The function to load them into the tab control: private void LaunchWPFApplication(string header, string pPath) { // Header - What loads in the tabs header portion. // pPath - Page where to send the user //Create a new browser tab object BrowserTab bt = tabMain.SelectedItem as BrowserTab; bt = new BrowserTab(); bt.txtHeader.Text = header; bt.myParent = BrowserTabs; //Load in the path try { Type formType = Type.GetType(pPath, true); bt.Content = (UserControl)Activator.CreateInstance(formType); } catch { MessageBox.Show("The specified user control : " + pPath + " cannot be found"); } //Add the browser tab and then focus BrowserTabs.Add(bt); bt.IsSelected = true; } And what I send to the function as an example: LaunchWPFApplication("Calculater", "foobar.AppCalculater"); But every time run, the application complains that the formType is null. I am confused on how to load the user control and curious if I'm sending the correct parameters.

• Determine iPhone user's country

  - by alku83

  I need to determine at startup what country a user is in, for an iPhone application. Presumably I will have to turn on location services and do some sort of reverse geocoding. I don't really want to use a third party web service if possible, are there any other suggestions for determining country from what location services provides? Initially, I only need to check whether the user is inside the US or not, but this may change in the future to add more countries. I understand that location can not always be determined or the user may have location services turned off. Basically, I just need to know if the user is detected as being inside the US, in order to turn off a specific feature.

• User permission to make a call

  - by Denis Petau

  There might have been a restriction on originating (making) calls (voice or data) from mobile phones without an explicit user permission i.e. a window would pop-up, asking the user to press 'Yes'/approve or 'No'/cancel for a call attempt made by a software application on that cellphone/mobile. There seems though to exist API for making calls, voice calls and data calls, on various embedded OS like WM, Symbian and Android. Do they require a user button-press then?

• How To Save Spring Security Logged In User In Session

  - by Brad Rhoads

  This code get's the currently logged in user, using the Spring Security Plugin (acegi): def principalInfo = authenticateService.principal() def person = null if (principalInfo != "anonymousUser" && principalInfo.username) { person = Person.findByUsername(principalInfo.username) } I would like then do: session.user = person This needs to be done after the user logs in. I can't figure out where to put my code to do this. It seem like it should be some place in the Login Controller, but I can't see where.

• .NET application per-machine/per-user licensing

  - by MainMa

  I am about to implement a very basic licensing feature for my application. A serial number may be granted per-machine (or per-operating-system) or per-user (as for CAL in Windows Server: if my application is used by several users on one machine or if it is used by one user on several machines). For per-operating-system licensing, I use SerialNumber of Win32_OperatingSystem. For per-user licensing, I use: WindowsIdentity currentIdentity = WindowsIdentity.GetCurrent(); if (currentIdentity != null) { SecurityIdentifier userSid = currentIdentity.User.AccountDomainSid; Console.WriteLine(userSid); } A hash of an obtained OS serial number or SID is then stored in the database, associated with application serial; each time the program starts, it queries the server, sending hash of OS SN/SID and application serial. Is it a right thing to do it or is it completely wrong? Will it work on every Windows machine? (For example, using motherboard serial is wrong)

• How to protect/monitor your site from crawling by malicious user

  - by deathy

  Situation: Site with content protected by username/password (not all controlled since they can be trial/test users) a normal search engine can't get at it because of username/password restrictions a malicious user can still login and pass the session cookie to a "wget -r" or something else. The question would be what is the best solution to monitor such activity and respond to it (considering the site policy is no-crawling/scraping allowed) I can think of some options: Set up some traffic monitoring solution to limit the number of requests for a given user/IP. Related to the first point: Automatically block some user-agents (Evil :)) Set up a hidden link that when accessed logs out the user and disables his account. (Presumably this would not be accessed by a normal user since he wouldn't see it to click it, but a bot will crawl all links.) For point 1. do you know of a good already-implemented solution? Any experiences with it? One problem would be that some false positives might show up for very active but human users. For point 3: do you think this is really evil? Or do you see any possible problems with it? Also accepting other suggestions.

• User signup in REST API

  - by Bhaktavatsalam Nallanthighal

  I have a PHP web application that I want to make accessible across multiple clients. So, I'm trying to make it more like an API. My question is: How would I handle the creation of new users using the API? If I have a URL like http://example.com/user/signup which takes new user details and creates a new user via a POST request, wouldn't it be a problem that people can misuse it and create fake users easily?

• Get UPN or email for logged in user in a .NET web application

  - by DrStalker

  I'm not a .NET developer, and I have a feeling this would be trivial for someone who is: I have a C# web application that makes user of the user credentials of the logged in user. Currently it uses the SID which comes from System.Security.Principal.WindowsIdentity.GetCurrent().User.Value I need to get either the users UPN login or email address (as defined in active directory) instead of the SID. GetCurrent() returns an object of type WindowsIdentity; looking in the details for WindowsIdentity Members: MSDN: WindowsIdentity Members I can't see anything that looks like it would give me either the UPN or email in there. How can I pull up that information to use, either by feeding the SID into some other function or calling something different in the first place.

• ReadOnly Property in Custom Column Types in Sharepoint

  - by Ray Booysen

  Hey all I'm creating a custom column in a feature for Sharepoint. It is essentially this: <Field Type="Integer" ID="<insert guid here>" ReadOnly="true" Name="xxx" DisplayName="XXX" Group="YYY" /> When the field is deployed and attached to a content type, the content type shows no instance of this field being attached. The documentation about ReadOnly is a bit vague but definitely states that the column will be available for viewing in a View. However, when I create a view it is not available. The moment I remove ReadOnly from the field, it is available on the content type without any problems. Any ideas?

• Remaking this loop by user?

  - by Elliot

  I'm wondering if theres a best practice for what I'm trying to accomplish... First we have the model categories, categories, has_many posts. Now lets say, users add posts. Now, I have a page, that I want to display only the current user's posts by category. Lets say we have the following categories: A, B, and C User 1, has posted in Categories A and B. In my view I have something like: <% @categories.select {|cat| cat.posts.count > 0}.each do |category| %> <%= category.name %><br/> <% category.posts.select {|post| post.user == current_user}.each do |post| %> <%= post.content %><br/> <% end %> <% end %> For the most part its almost there. The issue is, it will still show an empty category if any posts have been entered in it at all (even if the current user has not input posts into that category. So the question boils down to: How do I make the following loop only count posts in the category from the current user? <% @categories.select {|cat| cat.posts.count 0}.each do |category| % Best, Elliot

• Multidimensional Array with different types in java

  - by Christian

  I want to store a data structure thats a table with one column Strings and another column of Ints. List<Entry<String, Integer>> li = new LinkedList<Entry<String, Integer>>(); would do the job for a list but I would rather have the performance of an array. I tried Entry<String, Integer>[] = new Entry<String, Integer>[10]; but that doesn't seem to work.

• user table with javaDB and Hibernate from within grails

  - by Ralf

  let's see if I can ask this in an understandable way... I started with grails and created a domain class called user. As far as I understand, Hibernate is used to map this domain class to the database. This works pretty fine with hsqldb. Now I tried to switch to javaDB and get an error message because the table is called "user" (which seems to be a reserved word for javaDB). So a statement like create table user ... will result in an error message. create table "user" ... works, but Hibernate seems not put put the table name in quotes. How can I configure Hibernate to use quotes in order to make it work with my table name? PS: yes, I know, I could map the domain class to another table name... :-)
