  • EJB3.1 logout doesn't work

    - by Kevin
    Hello, I've got a problem with the authentication features of EJB3.1: With this code in a Servlet v3: log.info(""+request.getUserPrincipal()); log.info(""+request.getAuthType()); log.info("===^==="); request.logout() ; log.info(""+request.getUserPrincipal()); log.info(""+request.getAuthType()); request.authenticate(response) ; log.info("===v==="); log.info(""+request.getUserPrincipal()); log.info(""+request.getAuthType()); I would always expect to see the Username/login windows, because of the logout() function. Instead, it seems to be a 'cache' mechanism which repopulate the credential and cancel my logout ... Admin BASIC ===^=== null null ===v=== Admin BASIC is it a problem with my firefox, or something I'm missing in the Servlet code? Thanks

    - by Kevin
    Hello, I am trying to access a Linux system's NOR flash memory. I tried use __raw_readl(xxxxx) (through io_p2v) to read NOR memory data, but I failed. Is there any way I can access that memory? Will driver /dev/mem work for this? I guess not. it is only for the RAM maybe. Can anyone help?

  • Building ffmpeg with an executable output

    - by Kevin Galligan
    I generally don't like to ask such "you figure it out for me" questions, but I suspect this one will be really simple for a C++ guru. I want to build ffmpeg for Android, and I'd like it to output an executable rather than a set of libraries. We've been using the guardian project's build: https://github.com/guardianproject/android-ffmpeg It does produce what we want, but I've found tweaking it for different architectures to be, at best, unpleasant. I've gotten this version to build: https://github.com/appunite/AndroidFFmpeg It does a nice job of slicing and dicing different architectures, but produces a jni version. There is a long story as to why I want the exe, but I'll skip it for now. Is there a flag that needs to be flipped? Some path or other setting? I am at this point fully baffled. Thanks in advance.

  • visual studio 2005 problem with windows flying open

    - by Kevin
    I'm going through the problem of setting up a new computer and I'm having a problem with VS 2005. Whenever I start debugging all the windows (properties, watch, errorlist, stack, ...) pop up all over the place undocked. At this point I've tried docking them and closing them. When I stop debugging more windows pop up all undocked. This keeps happening over and over and over... I've tried closing and docking them but they keep popping out. Wasn't sure how to google this and my patience has grown thin with this whole process of moving to a new comp. Sincerely, Frustrated

  • Adding text labels to sliders in iPhone Settings application

    - by Kevin L.
    When configuring a Settings.bundle as part of an iPhone application bundle, it's trivial to add minimum and maximum value images to sliders (PSSliderSpecifier), but not simple maximum and minimum text labels. http://developer.apple.com/iPhone/library/documentation/PreferenceSettings/Conceptual/SettingsApplicationSchemaReference/Articles/PSSliderSpecifier.html iPhone gurus: Is anyone aware of a simple means to apply text labels to these sliders for use within the Settings application (therefore, no slider subclassing shenanigans; it all has to be done via a plist)? I suppose I could just use an image of the label but...ew. Bonus points if there's a way to show the current value of a slider in some sort of number format.

  • Boost.Log - Multiple processes to one log file?

    - by Kevin
    Reading through the doc for Boost.Log, it explains how to "fan out" into multiple files/sinks pretty well from one application, and how to get multiple threads working together to log to one place, but is there any documentation on how to get multiple processes logging to a single log file? What I imagine is that every process would log to its own "private" log file, but in addition, any messages above a certain severity would also go to a "common" log file. Is this possible with Boost.Log? Is there some configuration of the sinks that makes this easy? I understand that I will likely have the same "timestamp out of order" problem described in the FAQ here, but that's OK, as long as the timestamps are correct I can work with that. This is all on one machine, so no remote filesystem problems either.

  • Want to open Shadowbox gallery directly through Wordpress Navigation Menu

    - by Kevin A.
    I want to be able to open my shadowbox gallery in wordpress by directly clicking the portfolio link in the navbar. Right now it either opens the portfolio page I made with the gallery in it or opens images separately (without shadowbox), this was because I tried adding html to the Nav Label in the wordpress dashboard. Basically want to be able to add this html to the link in the menu dashboard while having the one PORTFOLIO link: <a href="/portfolio_images/fashion/01.jpg" rel="shadowbox[fashion]"> <a href="/portfolio_images/fashion/02.jpg" rel="shadowbox[fashion]"> <a href="/portfolio_images/fashion/03.jpg" rel="shadowbox[fashion]"> Thanks Main page with nav links

  • Rails Plugin for Multiple Ratings Per Model?

    - by Kevin
    I'm looking to add the capability of rating a model I have under several different categories like "Knowledgeable" "Organized", etc. Is there a plugin that will allow me to do this, and maybe even have a cool x/5 stars graphical representation as well?

  • SUM a pair of COUNTs from two tables based on a time variable

    - by Kevin O.
    Been searching for an answer to this for the better part of an hour without much luck. I have two regional tables laid out with the same column names and I can put out a result list for either table based on the following query (swap Table2 for Table1): SELECT Table1.YEAR, FORMAT(COUNT(Table1.id),0) AS Total FROM Table1 WHERE Table1.variable='Y' GROUP BY Table1.YEAR Ideally I'd like to get a result that gives me a total sum of the counts by year, so instead of: | REGION 1 | | REGION 2 | | YEAR | Total | | YEAR | Total | | 2010 | 5 | | 2010 | 1 | | 2009 | 2 | | 2009 | 3 | | | | | 2008 | 4 | I'd have: | MERGED | | YEAR | Total | | 2010 | 6 | | 2009 | 5 | | 2008 | 4 | I've tried a variety of JOINs and other ideas but I think I'm caught up on the SUM and COUNT issue. Any help would be appreciated, thanks!

  • Question about how AppFabric's cache feature can be used.

    - by Kevin Buchan
    Question about how AppFabric's cache feature can be used. I apologize for asking a question that I should be able to answer from the documentation, but I have read and read and searched and cannot answer this question, which leads me to believe that I have a fundamentally flawed understanding of what AppFabric's caching capabilities are intended for. I work for a geographically disperse company. We have a particular application that was originally written as a client/server application. It’s so massive and business critical that we want to baby step converting it to a better architected solution. One of the ideas we had was to convert the app to read its data using WCF calls to a co-located web server that would cache communication with the database in the United States. The nature of the application is such that everyone will tend to be viewing the same 2000 records or so with only occasional updates and those updates will be made by a limited set of users. I was hoping that AppFabric’s cache mechanism would allow me to set up one global cache and when a user in Asia, for example, requested data that was not in the cache or was stale that the web server would read from the database in the USA, provide the data to the user, then update the cache which would propagate that data to the other web servers so that they would know not to go back to the database themselves. Can AppFabric work this way or should I just have the servers retrieve their own data from the database?

  • Switching to HTML 5 and CSS3

    - by Kevin Sylvestre
    I constantly find myself creating sites using newer technologies (such as HTML 5 and CSS 3, then adding either backwards compatibility layers or porting entirely to XHTML 1.0 and CSS 2.1. This process often involves replacing CSS with sprite images and adding in flash components for advanced asynchronous support. My question is when can I can start to use the modern standards exclusively. Do I need to wait until Internet Explorer 9 is released or is it acceptable to request users switch to a "better" browser? Furthermore, if dropping compatibility for non HTML 5 browsers is an option, is it reasonable to ask mainstream users to install the Google Frame Frame? Thanks.

  • How do I register a Javascript function to run with every postback?

    - by Kevin
    I have a treeview in a user control. I need to run a javascript function with every synch postback to scroll the div it's in to the right position. I've got it working, but I think there has to be a "cleaner" way to do it. In the Page_Load function of the control, I have the following code. Is there a better way to do it? ScriptManager.RegisterStartupScript(this.UpdatePanel1, this.GetType(), "key" + DateTime.Now.Ticks, "RestorePosition();", true);

  • Clear button at uisearchbar not working at all

    - by kevin.ng
    I created a search bar programmatically and added to my view using the codes below: - (void)viewDidLoad { searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(xPositionForSearchBar, yPositionForSearchBar, widthForSearchBar, heightForSearchBar)]; UIView *bg = [[searchBar subviews] objectAtIndex:0]; searchBar.delegate = self; searchBar.placeholder = @"Search record"; for(UIView *view in searchBar.subviews){ if([view isKindOfClass:[UITextField class]]){ UITextField *tf = (UITextField *)view; tf.delegate = self; break; } } [bg removeFromSuperview]; [self.view addSubview: searchBar]; } The code is implemented with UISearchBarDelegate and UITextFieldDelegate. I have tried using - (void)searchBarCancelButtonClicked:(UISearchBar *)aSearchBar { NSLog(@"cancel clicked"); searchBar.text = @""; [aSearchBar resignFirstResponder]; } - (BOOL)textFieldShouldClear:(UITextField *)textField { NSLog(@"clear"); [self performSelector:@selector(searchBarCancelButtonClicked:) withObject:searchBar afterDelay: 0.1]; return YES; } and yet, the text inside the searchBar is not cleared at all when i click on the "clear button" - a circle with a "X" inside. The clear button works when I implemented it in IB. Wonder why? Kindly advice, many thanks.

  • DB fields not showing up in association custom queries?

    - by Kevin
    I have a notification list that the user can select different show options for different kinds of notifications along with how many results are returned. I'm keeping them in the user model because I want the custom sort to stay with the user between sessions. Here is the association in my user model: has_many :notifications, :class_name => "Notification", :foreign_key => "user_id", :conditions => ["won = ? and lost = ? and paid = ?", self.prefs_won, self.prefs_lost, self.prefs_paid], :limit => self.prefs_results.to_s But when I use the above code, Rails throws me an "unknown method" error for self.prefs_won. It is definitely a field in my database and set as a boolean value, but Rails can't find it... what's the problem?

  • jQuery validation: .each with form

    - by Kevin Brown
    If I have a form of about 40 questions, how do I apply the same rules to questions 1-20, and 21-40? For example: $("#form_survey").validate({ rules: { a_ +i: {max:12, maxlength:2}, }, messages: { a_ +i:{ max: "That's too much!" } } Where the "+i" is the ideal increment of +1... Should be easy, I'm just stuck on syntax...

  • Challenging yourself as a programmer?

    - by Kevin
    We used to be a Coldfusion development shop before hopping over to PHP in 2008, now we primarily develop custom Drupal websites. I enjoyed going from CF to PHP, but I feel like I am getting a bit stale. I have been looking at different things like Ruby, Python, Obj C (iPhone). The problem is, there just isn't enough time in the day. What would be a fun new thing to learn that would refresh me a bit and challenge myself to learn more?

  • Is long long in C++ known to be very nasty in terms of precision?

    - by Kevin
    The Given Problem: Given a theater with n rows, m seats, and a list of seats that are reserved. Given these values, determine how many ways two friends can sit together in the same row. So, if the theater was a size of 2x3 and the very first seat in the first row was reserved, there would be 3 different seatings that these two guys can take. The Problem That I'm Dealing With The function itself is supposed to return the number of seatings that there are based on these constraints. The return value is a long long. I've gone through my code many many times...and I'm pretty sure that it's right. All I'm doing is incrementing this one value. However, ALL of the values that my function return differ from the actual solution by 1 or 2. Any ideas? And if you think that it's just something wrong with my code, please tell me. I don't mind being called an idiot just as long as I learn something.

  • wxPython formatting questions

    - by Kevin
    I have an app I was working on to learn more about wxPython( I have been primarily been a scripter ). I forgot about it now I am opening it back up. It's a screen scraper, and I have it working almost the way I want it, going to build a regex parser to strip out the links in every scrape that I don't need. The questions I have are this. In it current state, if I check more than one site, it goes out and scrapes, and returns it in separate windows, the for:each section in the Clicked function. I want to put them in a frame, in the window, altogether. I also want to know if I can take the list they are read into and send it to a checklist, so someone could check off separate items, I want to build a save function and keep certain ones. In regards to a save function, I want to keep saved checks, are there calls to the widgets to save their states? I know it's a lot, but thanks for the help.

  • Amazon API library for Python?

    - by Kevin
    What Python libraries do folks use for querying Amazon product data? (Amazon Associates Web Service - used to be called E-Commerce API, or something along those lines). Based on my research, PyAWS (http://pyaws.sourceforge.net/) seems okay, but still pretty raw (and hasn't been updated in a while). Wondering if there's an obvious canonical library that I'm just missing.
