• Should I distinguish OpenIDs based on protocol prefix or not? http vs https

  - by Joannes Vermorel

  I have implemented a straightforward OpenID support for my ASP.NET app with DotNetOpenAuth. Yet I recently realized that the implementation was treating http://johndoe.example.com/ as a distinct user compared to https://johndoe.example.com. This lead to quite a few confused users. I am unsure what to do at this point. Is this a bug or a feature? Indeed, I can consider this behavior as a feature: if the user specifies the HTTPS, the user might not want the system to accept HTTP auth in the first place. On the other hand: if the user specifies HTTPS out of sheer cluelessness (the casual web visitor is clueless concerning the purpose of the "S" part), then rejecting it's authentication attempt is confusing. What is considered as the best practice?

• UISplitViewController Cannot Change the Master View Controller?

  - by Nex

  I am trying to change the master view controller (that appears in the popover in portrait, and on the left side in landscape) in a UISplitViewController. I'd like to switch between the master view controller being one of two different UIViewControllers (depending on an action taken elsewhere in my application). I am using the following: mySplitViewController.viewControllers = [NSArray arrayWithObjects:newMasterController, detailController, nil]; This correctly changes the master viewcontroller as you would expect in landscape mode. However it does not seem to change the viewcontroller used for the popover in portrait mode. I notice that the barbuttonitem to show this master view controller is just calling showMasterInPopover: on the splitviewcontroller, and so would expect it to work in portrait mode as well, but it does not. In fact, I can set the master view controller, see the new viewController correctly in landscape mode, rotate back to portrait, and the viewcontroller used in the popover is still the old one. Is this a bug?

• Open Source Contribution for a newbie programmer.

  - by sasayins

  Hi, I am teaching programming to my nephews and I want them to improve their skills by contributing to open source projects. Now my question is, do you know any open source project that suit for a newbie programmer. What I mean is, the project does not have a large codebase, the project is very interesting and the project is written in C because I chose C language as their starting language but you can suggest other project made in other language. My goal here are to improve their logic by reading other source codes, familiarize to the available development tools like bug tracker, version control system, etc. and open their interest in open source community. Thanks. =)

• How do I give MacPorts privileges?

  - by cojadate

  I tried to install PostgreSQL server development libraries using MacPorts and got the following: Warning: MacPorts running without privileges. You may be unable to complete certain actions (e.g. install). ---> Computing dependencies for postgresql-server-devel ---> Dependencies to be installed: postgresql-devel ---> Building postgresql-devel Error: Target org.macports.build returned: shell command failed Error: The following dependencies failed to build: postgresql-devel Error: Status 1 encountered during processing. To report a bug, see <http://guide.macports.org/#project.tickets> So I guess that means I need to running MacPorts with privileges and try again. Unfortunately I've no idea how to give MacPorts privileges. I'm running OS X 10.6.3

• Casting to generic type in Java doesn't raise ClassCastException?

  - by Kip

  I have come across a strange behavior of Java that seems like a bug. Is it? Casting an Object to a generic type (say, K) does not throw a ClassCastException even if the object is not an instance of K. Here is an example: import java.util.*; public final class Test { private static<K,V> void addToMap(Map<K,V> map, Object ... vals) { for(int i = 0; i < vals.length; i += 2) map.put((K)vals[i], (V)vals[i+1]); //Never throws ClassCastException! } public static void main(String[] args) { Map<String,Integer> m = new HashMap<String,Integer>(); addToMap(m, "hello", "world"); //No exception System.out.println(m.get("hello")); //Prints "world", which is NOT an Integer!! } }

• SML/NJ incomplete match

  - by dimvar

  I wonder how people handle nonexhaustive match warnings in the SML/NJ compiler. For example, I may define a datatype datatype DT = FOO of int | BAR of string and then have a function that I know only takes FOOs fun baz (FOO n) = n + 1 The compiler will give a warning stdIn:1.5-1.24 Warning: match nonexhaustive FOO n = ... val baz = fn : DT - int I don't wanna see warnings for incomplete matches I did on purpose, because then I have to scan through the output to find a warning that might actually be a bug. I can write the function like this fun baz (FOO n) = n + 1 | baz _ = raise Fail "baz" but this clutters the code. What do people usually do in this situation?

• Why don't web fonts in Firefox don't work on a different domain?

  - by mikez302

  I was experimenting with the fancy new OpenType font capability in Firefox 3.5 and I ran into a problem. I was trying to embed a font on a different domain than the page it would be used on, and it didn't work. I thought it may have been a bug, but from what I read on the MDC reference page, I noticed this note: In Gecko, web fonts are subject to the same domain restriction (font files must be on the same domain as the page using them), unless HTTP access controls are used to relax this restriction. It looks like they designed the browser that way on purpose. Out of curiosity, why would they do that? Is there any security risk with embedding a font? Or is it for legal trademark or copyright issues? Or something else?

• Activate different Maven profiles depending on current module?

  - by Yaba

  We have a multi module build with modules using different technologies, like Java and Flex. Is it somehow possible to activate different profiles based on the module that is compiled currently? I tried it with an activation like <profile> <id>flex</id> <activation> <file> <exists>${basedir}/src/main/flex</exists> </file> </activation> ... </profile But it didn't work, although the use of ${basedir} is documented in the Maven documentation (this is a bug in Maven). Is there a different possibility to have different activations based on the current module? Or does Maven only allow to activate a profile for all modules or not at all?

• What could cause a button on a UIActionSheet to "miss" on touches?

  - by Alex Gosselin

  I have a UIActionSheet as follows: UIActionSheet *sheet = [[UIActionSheet alloc] initWithTitle:[NSString stringWithFormat: @"Cancel New %@? Changes will be lost.", [creator propertyName]] delegate:self cancelButtonTitle:@"Stay Here" destructiveButtonTitle:@"Discard and Close" otherButtonTitles:@"Save and Close", nil]; [sheet showInView:self.view]; [sheet release]; It creates the action sheet, The buttons display, the Destructive button is on top, cancel button is on the bottom, other button (save and close) shows up in the middle, the top two buttons, (destructive and other) work fine, but the bottom button has a gap, so it is farther down than the other buttons. For some reason though, in order to press the button I need to touch where it would be if there was no gap. Touching the actual button doesn't work. Sorry if this isn't super clear, has anyone encountered something like this? I don't like to whip out the "I found a bug" card too fast, maybe I'm doing something wrong here.

• SQL Get Top 10 records by date

  - by Pselus

  I have a table full of bugs. The BugTitle is the page erroring and I also capture the error line. I would like to build an SQL Query that selects the top 10 bugs based on bugtitle and error line. I have this query: SELECT COUNT(BugTitle) AS BugCount, BugTitle, ErrLine FROM Bugs WHERE BugDate >= DateAdd(Day, -30, DateDiff(Day, 0, GetDate())) GROUP BY BugTitle, ErrLine ORDER BY BugCount, ErrLine DESC But I'm not sure if it's correct. I'm pretty sure that my test data only has 1 bug that happens on the same line but that's not showing up with this query. Can anyone help?

• Replacement background image not showing when using GreaseMonkey

  - by Dave C

  I'm trying to use GreaseMonkey to replace the background image of a DIV on bing.com. It's a pretty straightforward call to GM_addstyle: GM_addStyle(".sw_logo " +"{background:url('http://www.kpao.org/blog/kpao-bing-logo-inverse.png') " +"no-repeat 21px 7px transparent}"); However, the image doesn't show up. It's clearly visible in Firebug, and as I twiddle with the CSS in Firebug, I can get it to show up. But it doesn't stay. Any thoughts on why? Maybe it's a bug, but then maybe I'm missing something obvious. Thanks!

• How to get image height and width using java?

  - by Dick Song

  Is there any other way beside using imageIO.read to get image height and width? Because I encounter some issue that will lockup the thread. at com.sun.medialib.codec.jpeg.Decoder.njpeg_decode(Native Method) at com.sun.medialib.codec.jpeg.Decoder.decode(Decoder.java:87) at com.sun.media.imageioimpl.plugins.jpeg.CLibJPEGImageReader.decode(CLibJPEGImageReader.java:73) - locked <0xd96fb668> (a com.sun.media.imageioimpl.plugins.jpeg.CLibJPEGImageReader) at com.sun.media.imageioimpl.plugins.clib.CLibImageReader.getImage(CLibImageReader.java:320) - locked <0xd96fb668> (a com.sun.media.imageioimpl.plugins.jpeg.CLibJPEGImageReader) at com.sun.media.imageioimpl.plugins.clib.CLibImageReader.read(CLibImageReader.java:384) - locked <0xd96fb668> (a com.sun.media.imageioimpl.plugins.jpeg.CLibJPEGImageReader) at javax.imageio.ImageIO.read(ImageIO.java:1400) at javax.imageio.ImageIO.read(ImageIO.java:1322) This error only occurs on sun app server I suspect that it is a sun bug

• Nhibernate criteria query inserts an extra order by expression when using JoinType.LeftOuterJoin and Projections

  - by Aaron Palmer

  Why would this nhibernate criteria query produce the sql query below? return Session.CreateCriteria(typeof(FundingCategory), "fc") .CreateCriteria("FundingPrograms", "fp") .CreateCriteria("Projects", "p", JoinType.LeftOuterJoin) .Add(Restrictions.Disjunction() .Add(Restrictions.Eq("fp.Recipient.Id", recipientId)) .Add(Restrictions.Eq("p.Recipient.Id", recipientId)) ) .SetProjection(Projections.ProjectionList() .Add(Projections.GroupProperty("fc.Name"), "fcn") .Add(Projections.Sum("fp.ObligatedAmount"), "fpo") .Add(Projections.Sum("p.ObligatedAmount"), "po") ) .AddOrder(Order.Desc("fpo")) .AddOrder(Order.Desc("po")) .AddOrder(Order.Asc("fcn")) .List<object[]>(); SELECT this_.Name as y0_, sum(fp1_.ObligatedAmount) as y1_, sum(p2_.ObligatedAmount) as y2_ FROM fundingCategories this_ inner join fundingPrograms fp1_ on this_.fundingCategoryId = fp1_.fundingCategoryId left outer join projects p2_ on fp1_.fundingProgramId = p2_.fundingProgramId WHERE (fp1_.recipientId = 6 /* @p0 */ or p2_.recipientId = 6 /* @p1 */) GROUP BY this_.Name ORDER BY p2_.name asc, y1_ desc, y2_ desc, y0_ asc It is incorrectly putting the p2_name asc into the ORDER BY statement, and causing it to crash. This only happens when I use JoinType.LeftOuterJoin on my Projects criteria. Is this a known nhibernate bug? I'm using nhibernate 2.0.1.4000. Thanks for any insight.

• Jqm is not a function

  - by kris

  Hi all, I'm having some trouble with Jquery and JqModal, and I hope you are able to help, since I've been struggling for hours.. Having a single button element with an onclick action running my method "test" (shown below): $('#picture_form').jqm({ajax: '/test.php'}); $('#picture_form').jqmShow(); This will load the ajax content of test.php into my div element picture_form, shown using JqModal as its supposed to! Though when I close this window, and re-clicks the button I'm getting the error: $("#picture_form").jqm is not a function. As a solution I've tried to use the JqModal trigger function, and this leaves me able to open and close the JqModal windows as many times as I want to. Sadly I can only call the 'trigger' using test environment, in my production code I have to open the JqModal window using a function.. Does anyone have a clue why this 'bug' appears when calling the opening when using a function? Thanks in advance

• IE8 Inconsistent Rendering when Reloading

  - by leeand00

  I am working on fixing a website that doesn't work in the new release of IE8. After a bit I found out that you can force IE8 to render as IE7 with the following meta tag: <!-- Meta tag for IE8 so that it always displays the site in IE7 Compatibility mode --> <meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" /> I have found that although the page loads fine when you specify this meta-tag; However, when you click or press the refresh button after the initial load of the page, the page renders completely wrong (see bellow): This really seems like an IE8 bug to me, as I've never seen any other browser render inconstantly on a page refresh. As anyone else noticed this? Update! This was cause by having CompanionJS installed in IE8.

• Checkbox 'Checked' in ListView is restored after scrolling

  - by adrianrdzv

  I'm having the following problem: I have a ListActivity, which its ListView is composed by an icon, text and a checkbox (using LayoutInflater). The Adapter for the ListView extends ResourceCursorAdapter (i.e. the data source of the ListView is retrieved from a database, also the Checked status of each row) Everything works pretty Ok, except when I uncheck/check the checkbox in any row, if I scroll down until the modified checkbox is no longer visible, and then scroll up, the checkbox is restored to its original state. The database IS modified, this is not the problem (i.e. if I modify a row and exit the activity, and enter again, the modified row is displayed Ok). My guess is that this has something to do on how the list is rendered because for some reason the ListView "renders" the original state of all rows when it was first populated when scrolling. I've been looking around for this bug but I don't find anybody that had this problem. I appreciate any advice you have.

• BadAlloc X Error

  - by paultop6

  Hi Guys, Im having some problems with a GTK program im trying to build. When i compile it i keep getting this error: This probably reflects a bug in the program. The error was 'BadAlloc (insufficient resources for operation)'. (Details: serial 195 error_code 11 request_code 53 minor_code 0) Ive traced it down to the following command that appears to be causing it: gtk_box_pack_start(GTK_BOX (Top_Graph), Widget_Get (Graph_Cpu), TRUE, TRUE, 0); Now Top_Graph and Graph_Cpu are both GtkVbox Widgets. Has anyone ever seen an error like this, and could they give me some advice as to how it is caused Regards Paul

• Automatically Loading XIB for UITableViewController

  - by ACBurk

  Ran into something interesting, want to know if I'm doing something wrong or if this is the correct behavior. I have a custom UITableViewController. I ASSUMED (first mistake) that if you initialize as such: [[CustomTableController alloc] init]; it would automatically load from a XIB of the same name, CustomTableController.xib, if it is in the same directory and such. HOWEVER This does not work; doesn't load the XIB. BUT, if I change the parent class of my controller from 'UITableViewController' to 'UIViewController', EVERYHTING WORKS FINE! Calling: [[CustomTableController alloc] init]; loads the controller and view from my xib. Am I doing something wrong? Is this a bug? Expected behavior?

• ReportViewer height issue. Hiding scrollbars.

  - by Tommy Jakobsen

  Hi, I'm using MSSQL 2005 Reporting Services and in this case I need to display some reports on an ASP.NET page using the ReportViewer control (I guess thats the only way, right?). The problem is that I can't get the property SizeToReportContent to work. When displaying the report, I get a vertical scrollbar because the report is too large. It looks like an iframe window. Searching on google it seems to be a bug. It can be fixed by setting AsyncRendering to false but I don't want that. I need another solution. I was wondering if it's possible to set the height on the report element using JavaScript after the report has been loaded? Or do you know of another solution? This is really annoying. Thanks in advance.

• Howto troubleshoot vb6 dll 800a01ad error in c# application

  - by phq

  I have a dll that I created from a VB6 project that I am now using in a c# project. This has worked before but now when I try to return to the c# project to fix a bug, the program get a COMException stating roughly translated: Could not create an instance of COM-component with CLSID {085E3494-9F78-47D5-B0E6-FA460FD3CBED} from IClassFactory because of the following error: 800a01ad. So I try to create a new empty c# project with only one line in the main function: OurNamespace.OurClass foo = new OurNamespace.OurClass(); Which fails with the same error. I have registered the dll but that did not change the outcome of the problem. The problem only occurs on the machine I am currently at, still I'm interested to understand the problem so that I know how to fix it if it occurs on a customers computer.

• Wmode transparent and symbols issue with foreign keyboard

  - by Boun

  Hello, I have the known issue with wmode transparent and input textfield in my page. I know that the question is often asked but I have a special situation with that case. I need to embed my swf with wmode=transparent but in my swf I have an input textfield and the bug with "@" or "." symbols exists. I have a french keyboard and I decided to overcome this problem with a string replacement with the FirefoxWmodeFix class from Manmaru (see the link below). http://www.manmaru.fr/mlab/?p=95 It works for my keyboard but I need that "trick" with EN/DE/IT keyboard. Could anyone help me with the right combination of keys on different keyboard and different OS system to display "@" and "." symbols. I don't have any foreign Windows system to get the key code for each combination. Or if anyone has another solution, I will be pleased to hear that one. Thanks in advance for any help.
