• local match kickoff time

  - by Usagi Dreamy

  I'm working on a sports website and need to convert the server's match start time to local match start time. After much googling, I figured the fastest and most accurate way is to get the GMT offset value in JavaScript. The trouble is, I can't pass the GMT offset value to PHP. I've tried using both the PHP session and cookie variables, but both are always empty. The website doesn't require a user account, so there isn't any stored GMT value in the database. I'm trying to auto-detect each user's local timezone every time he/she visits the website, and then calculate the local match start time based on the timezone offset. Can someone please advise me? Thanks.

• Making JSON Feed Work Server to Server

  - by Oscar Godson

  I have a JSON feed (which I don't directly control, I have to ask the server admins to update it), that is returning NULL, or otherwise not working when I try to access it from another server. The actual feed works fine, but I can't get it to work like a normal API. Why can I use Flickr, WhitePages, Twitter, etc's JSON APIs, but for: http://portlandoregon.gov/shared/cfm/json.cfm It returns NULL in the browser when using JS. If I call it on the same server, it's fine though. If this is a server issue, what do I ask the admins to change, and if this is a local (browser) based issue, what am I doing wrong for this one feed that works for every other JSON API?

• CRXIR2 doesn't work with VS2010 on Windows 7 nor on Vista

  - by tangens

  We're upgrading from VS2005 to VS2010. We are almost there but there is a problem with Crystal Reports. We use the RDC (COM-based) component within our C++ application. On Windows 7 or on VISTA, I can't get the viewer nor the designer controls working. I get Access Violations when the control is activated: // from atlhost.h (line 2208) hr = m_spOleObject->DoVerb(OLEIVERB_INPLACEACTIVATE, NULL, spClientSite, 0, m_hWnd, &m_rcPos); The strange thing is that when I run the same exe on a XP machine, it seems to work. We basically use "AtlAxWin100" window class to host the Crystal report control ("CrystalReports11.ActiveXReportViewer.1") in. I'm using the SP6 version of Crystal reports so that's the latest version. Also, when I compile the same code with VS2005 and run it on Windows7 or Vista everything works out just fine. Does anybody have any idea about what might cause the problem, or ideas for further investigations?

• Changing the color of a Rebol button

  - by Dave Matuszek

  I want to ask multiple choice questions in Rebol. Possible answers will be on buttons. I want to turn a button red when it is clicked and it is the wrong answer. When the correct button is pressed, I want to proceed to the next question. I can change the color of a box (mybox/color: red show mybox). I can set up a toggle with two colors (but I can't change it based on the result of an arbitrary test (is the answer correct?). It seems like there is probably a simple way to change the color of a button, without having to create my own button-like face objects. Isn't there?

• how to insert the correct activex object in a MFC dialog

  - by kellogs

  More exactly, the web browser control. In a WM6 dialog based MFC project. This is driving me nuts. Mr Google does not know a thing on this matter. I have tried embedding the "Microsoft Webbrowser Control" in my dialog box but at runtime I get some class not register error. I have heard that this happens because "Microsoft Webbrowser Control" is the windows desktop control, not the windows mobile one. Otherwise, I find it quite hard to believe that this control is really not registered even on the emulator (if it really wasn't registered, PIE would not start). Anybody used the webbrowser engine in a WM(6) MFC applications ? Even a CLSID would help... Thank you

• Linux friendly (.NET/Mono) browser object?

  - by HankB

  Hi folks, A friend of mine (familiar with C# and .NET on Windows) has asked how to port some functionality to a Linux host. This functionality is based on a JSP web page that fetches some data from the host server and displays it in a banner on a page. His Win/C#/.NET code simply creates a browser object which loads the page and he then inspects the resulting object to extract the data. I'm wondering what alternatives exist to duplicate this function on Ubuntu Linux. I'm not certain that the necessary libraries exist on this installation. I can assume that things like Perl and Python are ubiquitous, but I am not familiar with any libraries that include a browser object capable of executing javascript and exposing the results to another program. Any suggestions that lead in this direction are welcome. Thanks!

• Detach many subdirectories into a new, separate Git repository

  - by prisonerjohn

  This question is based on http://stackoverflow.com/questions/359424/detach-subdirectory-into-separate-git-repository Instead of detaching a single subdirectory, I want to detach a couple. For example, my current directory tree looks like this: /apps /AAA /BBB /CCC /libs /XXX /YYY /ZZZ And I would like this instead: /apps /AAA /libs /XXX The --subdirectory-filter argument to git filter-branch won't work because it gets rid of everything except for the given directory the first time it's run. I thought using the --index-filter argument for all unwanted files would work (albeit tedious), but if I try running it more than once, I get the following message: Cannot create a new backup. A previous backup already exists in refs/original/ Force overwriting the backup with -f Any ideas? TIA

• Writing a simple batch file to setup a variable?

  - by Sam

  I want to write a simple batch file where i want to setup a environment variable based on the machine architecture. It is as below: set ARCH=%PROCESSOR_ARCHITECTURE% echo %ARCH% if %ARCH%==x86 ( set JAVA_ROOT=C:\Progra~1\Java\j2re1.4.2_13 ) else ( set JAVA_ROOT=C:\Progra~2\Java\j2re1.4.2_13 ) echo JAVA_ROOT is %JAVA_ROOT% On 64-bit machine where the architecture is 'AMD64' the JAVA_ROOT will be displayed as 'C:\Progra~2\Java\j2re1.4.2_13' at the echo statement. But when i run an application that uses this file, the first value of JAVA_ROOT would be picked up 'C:\Progra~1\Java\j2re1.4.2_13'. I don't have any idea why it goes in the 'if' part even though i am running this on 64-bit Windows7. When i echoed the

• How to load an RSA key from binary data to an RSA structure using the OpenSSL C Library?

  - by Andreas Bonini

  Currently I have my private key saved in a file, private.key, and I use the following function to load it: RSA *r = PEM_read_RSAPrivateKey("private.key", NULL, NULL, NULL); This works perfectly but I'm not happy with the file-based format; I want to save my key in pure binary form (ie, no base64 or similar) in a char* variable and load/save the key from/to it. This way I have much more freedom: I'll be able to store the key directly into the application const char key[] { 0x01, 0x02, ... };, send it over a network socket, etc. Unfortunately though I haven't found a way to do that. The only way to save and load a key I know of reads/saves it to a file directly.

• Adding image to navigation bar

  - by 4thSpace

  I'd like an image to take up all of a navigation bar. This is the navigation that comes with a navigation based app. It appears on the RootViewController with the accompanying UITableView. I've seen some examples of how this might work. Set navigation bar title: UIImage *image = [UIImage imageNamed:@"TableviewCellLightBlue.png"]; UIImageView *imageView = [[UIImageView alloc] initWithImage:image]; [self.navigationController.navigationBar.topItem setTitleView:imageView]; The problem there is it only covers the title rather than the entire navigation bar. There is also this thread: http://discussions.apple.com/message.jspa?messageID=9254241#9254241. Towards the end, the solution looks to use a tab bar, which I'm not using. It is that complicated to set a navigation bar background? Is there some other simpler technique? I'd like to have a background for the navigation and still be able to use title text.

• combination of open source licenses

  - by Nicola Montecchio

  Hi I'm about to release some software as open source. It uses Lucene (Apache license) and jopt simple (MIT license). Are there any constraints on the license that I am going to apply to my own software? In particular, it is an adaptation of Lucene for performing content-based search on audio (so, many classes are inherited and in one case copied with a little modification). It only uses jopt simple for handling command line arguments (i.e. no modification at all, just "import" and "new OptionParser..."). Thanks for your help Nicola Montecchio

• Is it possible to change the pane locations in Chrome Developer Tools?

  - by T.J. Crowder

  When debugging browser-based apps using Google Chrome's Developer Tools, is there a way to change the locations of the various panes? E.g., the Watch Expressions, the Call Stack, the code pane, etc.? The defaults are okay (console at bottom, code pane upper left, a column of Watch Expressions, Call Stack, Scope Vars, etc. in the upper right), but I'd rather swap things around a bit of it's possible. There doesn't seem to be anything to grab (other than for sizing) and I haven't found a way in my searching so far, but there are (still) some things about Chrome's options that aren't ... well-advertised in the UI, shall we say :-), especially around developer tools.

• Apache Shiro, INI-Configuration, Perms per URL: How to get URL params?

  - by Marcus Schultö

  I want to use Apache Shiro[1] in my JSF-Application to perform URL-based authorization checks, configuration done in shiro.ini As I see in the Shiro-documentation[2] there is a way to use a "perms"-filter /remoting/rpc/** = authc, perms["remote:invoke"] In my scenario I want this functionality, but on entity-level[3], where the entity-Id is in the http-request # "Open settings for user with id=123": # /user/settings.xhtml?user_id=123 /user/settings.xhtml = perms["user:update:XXX"] So, how do I do this with Shiro? How to I tell the perms-filter to check for http-params? Or is this supposed to be done in my Realm-Implemenation, concrete by calling FacesContext? [1] https://shiro.apache.org [2] https://shiro.apache.org/web.html#Web-webini [3] This can be done at least programmatically: SecurityUtils.getSubject().isPermitted("printer:query:lp7200") https://shiro.apache.org/permissions.html

• Spring-webflow error popup tweak

  - by igorp1024

  There is a link in a spring-webflow2 based application which start different flows. Flows are shown in popup (popup=true). If the session is expired or server is unavailable, the spring-webflow shows small empty popup with "Ajax Request Error" tooltip shown on mouse over. Is it possible to tweak the popup in order to give the user an ability to either re-login or to just close the popup and retry the request? EDIT: Or maybe some ideas how to force Spring-Dojo to make a redirect to login page?

• How to change password hashing algorithm when using spring security?

  - by harry

  I'm working on a legacy Spring MVC based web Application which is using a - by current standards - inappropriate hashing algorithm. Now I want to gradually migrate all hashes to bcrypt. My high level strategy is: New hashes are generated with bcrypt by default When a user successfully logs in and has still a legacy hash, the app replaces the old hash with a new bcrypt hash. What is the most idiomatic way of implementing this strategy with Spring Security? Should I use a custom Filter or my on AccessDecisionManager or …?

• Updating Label on previously loaded view?

  I am working on a simple app tab-bar based application that has two views. The first is the main application and the second is a simple instruction screen. What I am trying to do is create a update a label on that second screen as things change in the main app. Because the second screen is only simple with one label and some text I am not unloading it once its loaded. After the first viewDidLoad I can update the label just fine, but after that is there a way to catch successive view switches from the tab-bar menu so I can update the label? many thanks gary

• Database over 2GB in MongoDB

  - by configurator

  We've got a file-based program we want to convert to use a document database, specifically MongoDB. Problem is, MongoDB is limited to 2GB on 32-bit machines (according to http://www.mongodb.org/display/DOCS/FAQ#FAQ-Whatarethe32bitlimitations%3F), and a lot of our users will have over 2GB of data. Is there a way to have MongoDB use more than one file somehow? I thought perhaps I could implement sharding on a single machine, meaning I'd run more than one mongod on the same machine and they'd somehow communicate. Could that work?

• Smartest way to import massive datasets into a Rails application?

  - by williamjones

  I've got multiple massive (multi gigabyte) datasets I need to import into a Rails app. The datasets are currently each in their own database on my development machine, and I need to read from them and create rows in tables in my Rails database based on the information they contain. The tables in my Rails database will not be exactly the same as the tables in the source databases. What's the smartest way to go about this? I was thinking migrations, but I'm not exactly sure how to connect the migration to the databases, and even if that is possible, is that going to be ridiculously slow?

• How should i build my GUI in Qt ?

  - by Apollo

  I am wondering which way is the best to start building a GUI+SOFT in Qt. I am trying to build a sound media player based on a MVC pattern. Until now i have found 3 ways to do so. 1- Should I use a .ui file thanks to Qt designer, is it flexible enough ? 2- Should I use QML to make the design than integrate it to a C++ development ? 3- Should I just start from scratch and do it by hand without Qt Designer and using Qt library ? Thank you very much for your answers.
