• How do I change the color settings in emacs23 running in a terminal emulator?

  - by Anonymous

  I use xterm and set its appearance in ~/.Xdefaults: XTerm*background: paleTurquoise XTerm*foreground: black I also use emacs, but set its appearance differently in ~/.emacs: (set-background-color "black") (set-foreground-color "yellow") I usually run emacs within the terminal emulator with emacs -nw, rather than creating a separate X window. For some reason, this doesn't work properly for emacs23; instead, emacs retains the pale turquoise background of my xterm window. Looking at what's new in emacs23, I noted that: ** When running in a new enough xterm (newer than version 242), Emacs asks xterm what the background color is and it sets up faces accordingly for a dark background if needed (the current default is to consider the background light). So it's a feature, not a bug? Anyway, is there some way that I can I tell emacs23 to ignore the xterm background settings when running in console mode, and use the settings in ~/.emacs instead? I'll also note that: It works fine in emacs23 running in a separate X window (without the -nw option). It worked fine in emacs22; and I'm not really sure whether I need to use emacs23... Running M-x set-background-color within emacs23 -nw has no effect. It's not just xterm: the same problem exists with $TERM=cygwin, for example.

• UIImagePickerController causing sqlite errors (Simulator only)

  - by MrHen

  When I display a UIImagePickerController in a UIPopoverController the console outputs the following warnings: sqlite error 8 [attempt to write a readonly database] sqlite error 8 [attempt to write a readonly database] sqlite error 8 [attempt to write a readonly database] sqlite error 1 [no such column: duration] sqlite error 1 [no such column: duration] sqlite error 8 [attempt to write a readonly database] sqlite error 8 [attempt to write a readonly database] sqlite error 8 [attempt to write a readonly database] Here is the code that displays the picker: - (void)openImagePickerController:(id)sender { //TODO only open one at a time UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init]; //imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera; imagePicker.delegate = self; [self presentViewController:imagePicker sender:sender animated:YES modal:YES]; [imagePicker release]; } - (void)presentViewController:(UIViewController *)vc sender:(id)sender animated:(BOOL)animated modal:(BOOL)modal { BOOL useNavController = NO; //if((void *)UI_USER_INTERFACE_IDIOM() != NULL && if(UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) { //are we on an iPad? Class popoverClass = NSClassFromString(@"UIPopoverController"); if(!popoverClass) { useNavController = YES; } else { if(currentPopover == nil || currentPopover.contentViewController != vc) { if(currentPopover != nil) { [currentPopover dismissPopoverAnimated:animated]; [currentPopover.delegate popoverControllerDidDismissPopover:currentPopover]; } UIPopoverController *popover = [[popoverClass alloc] initWithContentViewController:vc]; currentPopover = popover; currentPopover.delegate = self; [popover presentPopoverFromBarButtonItem:sender permittedArrowDirections:UIPopoverArrowDirectionAny animated:animated]; } } //[aPopover release]; } else { useNavController = YES; } if(useNavController) { if(modal) { [self presentModalViewController:vc animated:animated]; } else { [self.view addSubview:vc.view]; } } } Stepping with the debugger shows that the errors occur after [UIPopoverController presentPopoverFromBarButtonItem:permittedArrowDirections:animated: runs. Of note: The program continues running just fine No noticeable weirdness in UIImagePickerController's behavior when selecting an image or canceling Happens in Simulator 3.2 Unable to reproduce on iPad running 3.2 Is this just another simulator bug?

• IIS 6 forces AppRoot/Starting Point to upper case when Virtual Directory is imported from a file

  - by user276464

  I have searched the web for this and couldn't find anything (well one remotely relevant post), so here I am. We have multiple ASP.NET apps in IIS 6 using Forms Authentication with dedicated path for each app. Since path is case sensitive it must match URL's path section exactly. However, because of an incorrect casing in IIS 6 Metabase for AppRoot (or Starting Point in IIS UI) bowser doesn't send Form cookie to the server whenever URL is previously resolved on the server and sent to client in incorrect case. Example: App URL = "https://Test.net/Application1" Cookie path = /Application1 Metabase AppRoot = /LM/W3SVC/1393818691/ROOT/APPLICATIONPATH1 Resolved URL = "https://Test.net/APPLICATIONPATH1" Now to the root cause... We create virtual directories on test server manually in a specific case (matches Path for each application). We then export virtual directory using UI to an XML file, which is then imported to another server (let's say production), at which point IIS decides to uppercase AppRoot element of the metabase. Can anyone shed some light on this? Is there a setting on IIS I am not aware of? I am trying to avoid manual edit of metabase after the import. Is that a bug?

• Overriding MSBuildExtensionsPath in the MSBuild task is flaky

  - by Stuart Lange

  This is already cross-posted at MS Connect: https://connect.microsoft.com/VisualStudio/feedback/details/560451 I am attempting to override the property $(MSBuildExtensionsPath) when building a solution containing a C# web application project via msbuild. I am doing this because a web application csproj file imports the file "$(MSBuildExtensionsPath)\Microsoft\VisualStudio\v9.0\WebApplications\Microsoft.WebApplication.targets". This file is installed by Visual Studio to the standard $(MSBuildExtensionsPath) location (C:\Program Files\MSBuild). I would like to eliminate the dependency on this file being installed on the machine (I would like to keep my build servers as "clean" as possible). In order to do this, I would like to include the Microsoft.WebApplication.targets in source control with my project, and then override $(MSBuildExtensionsPath) so that the csproj will import this included version of Microsoft.WebApplication.targets. This approach allows me to remove the dependency without requiring me to manually modify the web application csproj file. This scheme works fine when I build my solution file from the command line, supplying the custom value of $(MSBuildExtensionsPath) at the command line to msbuild via the /p flag. However, if I attempt to build the solution using the MSBuild task in a custom msbuild project file (overriding MSBuildExtensionsPath using the "Properties" attribute), it fails because the web app csproj file is attempting to import the Microsoft.WebApplication.targets from the "standard" Microsoft.WebApplication.targets location (C:\Program Files\MSBuild). Notably, if I run msbuild using the "Exec" task in my custom project file, it works. Even more notably, the FIRST time I run the build using the "MSBuild" task AFTER I have run the build using the "EXEC" task (or directly from the command line), the build works. Has anyone seen behavior like this before? Am I crazy? Is anyone aware of the root cause of this problem, a possible workaround, or whether this is a legitimate bug in MSBuild?

• WatiN NativeElement.GetElementBounds() - What is the unit of measurement?

  - by Brian Schroer

  When I'm testing with WatiN, I like to save screenshots. Sometimes I don't really need a picture of the whole browser window though - I just want a picture of the element that I'm testing. My attempt to save a picture of an element with the code below resulted in a picture of a block box, because elementBounds.Top points to a pixel position way past the bottom of the screen. The elementBounds.Width and .Height values also appear to be about half what they should be. Is this a WatiN bug, or are these properties in a different unit of measure that I have to convert to pixels somehow? public static void SaveElementScreenshot (WatiN.Core.IE ie, WatiN.Core.Element element, string screenshotPath) { ScrollIntoView(ie, element); ie.BringToFront(); var ieClass = (InternetExplorerClass) ie.InternetExplorer; Rectangle elementBounds = element.NativeElement.GetElementBounds(); int left = ieClass.Left + elementBounds.Left; int top = ieClass.Top + elementBounds.Top; int width = elementBounds.Width; int height = elementBounds.Height; using (var bitmap = new Bitmap(width, height)) { using (Graphics graphics = Graphics.FromImage(bitmap)) { graphics.CopyFromScreen (new Point(left, top), Point.Empty, new Size(width, height)); } bitmap.Save(screenshotPath, ImageFormat.Jpeg); } }

• App session cookie not being created in Rails, sporadically

  - by James

  Hi everyone, This is an issue sporadically for very few users, however we haven't been able to replicate it. However I have now got a Chrome instance (Mac) which is reproducing the error (for some unknown reason), and I hope to not restart it until I have this nailed! Rails application, using memcached for session store. While the bug manifests in the _app_session_id cookie not being created, our javascript-generated cookie test and app-generated language cookies are being created successfully. This means that InvalidAuthenticityToken errors are thrown for every form that is submitted by those afflicted - people can't log into the app. The error occurs across all browsers - had reports for IE7 and Firefox (which most users use). Switching to another browser often fixes the issue (though not always), and standard cache-cookie-clear tactics do not. So now that I have got Chrome open which is having the same issue - in development, staging and live environments (meaning http and https). All other browsers are fine. I've restarted the servers and restarted memcached. I don't really want to restart Chrome - in the risk that the issue does go away with that (having said that, it hasn't worked for users). I've been tcpdumping the requests - and although I'll keep digging, I'd love it if anyone had any suggestions, places to start looking, anything. This is really painful ;) Thanks!

• Duplicate entries on mysql on insert using doctrine

  - by Nikos Galis

  Hi all! I am facing a very weird problem with mysql and doctrine [with help of codeIgniter]. I am trying to make a simple migration script taking all records from one table and after a little process, saving them to another. However, on my laptop [running windows and wamp] I get double numbers of the original table records to have been copied to the destination table. In my colleagues' laptops, everything works fine! We are all using mysql 5.0.86 [plus windows plus wamp]. Here is the code : function buggy_function(){ $this->db(); //get db connection $q = Doctrine_Query::create()->from('Oldtable r'); $oldrecords = $q->fetchArray(); $count = 0; foreach ($oldrecords as $oldrecord){ $newrecord = new NewTableClass(); $newrecord->password = md5($oldrecord['password']); $newrecord->save(); echo $newrecord->id. ' Id -> saved.' } } Simple as that! I have 39 records on the Old table and I am getting 78 records in the new table, which are exactly the same records, except from the unique primary key. It seems as if the script runs twice. But the output of the script is the following : 1 Id -> saved. 2 Id -> saved. ... ... 39 Id -> saved. Do you have any idea why this is happening? Any known bug for mysql? Thank you in advanced!'

• datanucleus enhancer & javaw: "the parameter is incorrect"

  - by Riley

  I'm on windows XP using eclipse and the datanucleus enhancer for a gwt + gae app. When I run the enhancer, I get an error: Error Thu Oct 21 16:33:57 CDT 2010 Cannot run program "C:\Program Files\Java\jdk1.6.0_18\bin\javaw.exe" (in directory "C:\ag\dev"): CreateProcess error=87, The parameter is incorrect java.io.IOException: Cannot run program "C:\Program Files\Java\jdk1.6.0_18\bin\javaw.exe" (in directory "C:\ag\dev"): CreateProcess error=87, The parameter is incorrect at java.lang.ProcessBuilder.start(Unknown Source) at com.google.gdt.eclipse.core.ProcessUtilities.launchProcessAndActivateOnError(ProcessUtilities.java:213) at com.google.appengine.eclipse.core.orm.enhancement.EnhancerJob.runInWorkspace(EnhancerJob.java:154) at org.eclipse.core.internal.resources.InternalWorkspaceJob.run(InternalWorkspaceJob.java:38) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:55) Caused by: java.io.IOException: CreateProcess error=87, The parameter is incorrect at java.lang.ProcessImpl.create(Native Method) at java.lang.ProcessImpl.<init>(Unknown Source) at java.lang.ProcessImpl.start(Unknown Source) ... 5 more I've had this problem before, and it was due to a long classpath. I just spent an hour and a half shortening my classpath by moving libraries around and even moving my eclipse install, but with no luck. Any ideas about where I should start to look for an answer? The error message doesn't include any information about what directory it's in or anything. It's kind of infuriating! Is it possible to make the output of javaw more verbose? Is it possible to get around this class-path size bug?

• Namespace Problem

  - by Tarik

  Hello, Normally we all do use using System.Linq; and using System.Data.Linq; for example on the code-behind and expect we can reach the members of these namespaces from Source Code like <%= Something.First()%> but when I wrote it, asp.net said it couldn't find First() in the context and I had to add <%@ Import Namespace="System.Linq" which looked very weird to me but it worked out. Since they are targeting at the same class why they both need separate namespace importing. Code-behind : using System; using System.Data.Linq; using System.Linq; using System.Text namespace Something { class Items : System.Web.UI { //... } } but also I need to add the same Linq namespace on the Html Source part <%@Import Namespace="System.Linq"%> Do I know something wrong or this is some kind of bug in asp.net. I thought when the page is compiling, asp.net combines these two classes and converts html source code into cs class and indicates the control in Control c= new Control(); hierarchy. Thanks in advance.

• Why does my DataTemplate break the WPF designer?

  - by PRINCESS FLUFF

  Why does the DataTemplate line break the WPF designer in Visual Studio 2008? The program compiles and runs properly. The DataTemplate is applied as it should. However the entire DataTemplate block of code is underlined in red, and when I simply "build" the program without running, I get the error "Type reference cannot find public type named 'Character'" How come it can't find it in the designer yet the program applies the template properly? <UserControl x:Class="WPF_Tests.Tests.TwoCollecViews.TwoViews" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:DetailsPane="clr-namespace:WPF_Tests.Tests.DetailsPane" > <UserControl.Resources> <DataTemplate DataType="{x:Type DetailsPane:Character}"> <StackPanel Orientation="Horizontal"> <TextBlock Text="{Binding Path=Name}"></TextBlock> </StackPanel> </DataTemplate> </UserControl.Resources> <Grid> <ListBox ItemsSource="{Binding Path=Characters}" /> </Grid> </UserControl> EDIT: I am being told that this may be a bug in Visual Studio 2008, as it worked correctly in 2010. You can download the code here: http://www.mediafire.com/?z1myytvwm4n - The Test/TwoCollec xaml file's designer will break with this code.

• Investigating the root cause behind SharePoint's "request not found in the TrackedRequests"

  - by Muhimbi

  We have a long standing issue in our bug tracking system about the dreaded "ERROR: request not found in the TrackedRequests. We might be creating and closing webs on different threads." message in SharePoint's trace log. As we develop Workflow software for the SharePoint market, we look into this issue from time to time to make sure it is not caused by our products. I have personally come to the conclusion that this is a problem in SharePoint, but perhaps someone else can prove me wrong. Here is what I know: According to the hundreds of search results returned by Google on this topic, this issue appears to be mainly related to SharePoint Workflows, both SharePoint Designer and Visual Studio based workflows. Assuming ULS logging is set to Monitorable, the easiest way to reproduce this problem is to create a new SharePoint Designer Workflow, attach it to a document library, set it to auto start on add/update, don't add any actions, save the workflow and upload a file to the document library. The error is only visible in the SharePoint trace log, it does not appear to impact the execution of the workflow at hand. I have verified that the problem occurs on 32 bit as well as 64 bit systems, Win2K3 and 2K8, WSS and MOSS with SharePoint versions up to the December 2009 Cumulative Update (6524). The problem does not occur when a workflow is started manually. There are dozens of related posts on MSDN Forums, hundreds on Google, one on StackOverflow and none on SharePoint Overflow. There appears to be no answer. Does anyone have any idea about what is going on, what is causing this and if we should worry or file this under 'Red Herrings'.

• Rails 2.3.11 Server Crashing After 4 Requests

  - by Taka

  I have a Rails 2.3.11 application running on my local Windows machine using InstantRails. I cd to my application directory, run ruby script/server to start the server running, and point my browser to localhost:3000. I get the page I expect, and am able to click a few links to other pages (all of them are static). The problem starts when I load the 4th page or so.

• SQLite on iPhone - Techniques for tracking down multithreading-related bugs

  - by Jasarien

  Hey guys, I'm working with an Objective-C wrapper around SQLite that I didn't write, and documentation is sparse... It's not FMDB. The people writing this wrapper weren't aware of FMDB when writing this code. It seems that the code is suffering from a bug where database connections are being accessed from multiple threads -- which according to the SQLite documentation won't work if the if SQLite is compiled with SQLITE_THREADSAFE 2. I have tested the libsqlite3.dylib provided as part of the iPhone SDK and seen that it is compiled in this manner, using the sqlite_threadsafe() routine. Using the provided sqlite library, the code regularly hits SQLITE_BUSY and SQLITE_LOCKED return codes when performing routines. To combat this, I added some code to wait a couple of milliseconds and try again, with a maximum retry count of 50. The code didn't contain any retry logic prior to this. Now when a sqlite call returns SQLITE_BUSY or SQLITE_LOCKED, the retry loop is invoked and the retry returns SQLITE_MISUSE. Not good. Grasping at straws, I replaced the provided sqlite library with a version compiled by myself setting SQLITE_THREADSAFE to 1 - which according to the documentation means sqlite is safe to be used in a multithreaded environment, effectively serialising all of the operations. It incurs a performance hit, that which I haven't measured, but it ridded the app of the SQLITE_MISUSE happening and seemed to not need the retry logic as it never hit a busy or locked state. What I would rather do is fix the problem of accessing a single db connection from multiple threads, but I can't for the life of me find where it's occurring. So if anyone has any tips on locating multithreaded bugs I would be extremely appreciative. Thanks in advance.

• Android java.lang.VerifyError for private method with annotated argument.

  - by alex2k8

  I have a very simple project that compiles, but can't be started on Emulator. The problem is with this method: private void bar(@Some String a) {} // java.lang.VerifyError The issue can be avoided if annotation removed private void bar(String a) {} // OK or the method visibility changed: void bar(@Some String a) {} // OK public void bar(@Some String a) {} // OK protected void bar(@Some String a) {} // OK Any idea what is wrong with original method?

• CSS gradients in IE7 & IE8 is causing text to become aliased

  - by Cory

  I'm attempting to use a CSS gradient in a div containing some text. With Gecko and Webkit, the text displays fine. In IE7 & IE8 the text appears aliased (jaggy). I came across this blog stating: "we decided to disable ClearType on elements that use any DXTransform". IE Blog: http://blogs.msdn.com/ie/archive/2006/08/31/730887.aspx That was back in 2006; 3.5 years later, I assume this bug would be fixed, but it's not. Is there a way to do this in IE8 without resorting to stuffing a repeating background image in the div? Here's an example of what I mean. <style> div { height: 50px; background: -moz-linear-gradient(top, #fff, #ddd); background: -webkit-gradient(linear, left top, left bottom, from(#fff), to(#ddd)); filter: progid:DXImageTransform.Microsoft.gradient(startColorstr=#ffffffff, endColorstr=#ffdddddd); } </style> <div>Hello World</div> <p>Normal text</p> In IE, the text in the div is aliased (jaggy), and the text in the paragraph is not. Any solution that doesn't involve images would be greatly appreciated.

• SAL and SAR by 0 errors

  - by Roy McAvoy

  I have discovered a bug in some assembly code I have been working with but can't figure how to fix it. When shifting left by 0 the result ends up being 0 instead of jut the number. The same applies when shifting to the right. Any and all help is much appreciated. function sal(n,k:integer):integer; begin asm cld mov cx, k @1: sal n, 1 loop @1 end; sal:= n; end; function sar(n,k:integer):integer; begin asm cld mov cx, k @1: sar n, 1 loop @1 end; sar:=n; end; I have tried to changed them in the following way and it still does not work properly. function sal(n,k:integer):integer; begin asm cld mov cx, k jcxz @done @1: sal n, 1 loop @1 @done: end; sal:= n; end; function sar(n,k:integer):integer; begin asm cld mov cx, k jcxz @done @1: sar n, 1 loop @1 @done: end; sar:=n; end;

• Problem creating checklist (similar to TouchCells sample code) app for iPhone. Random cells get chec

  - by Jonah

  I've been having a problem creating a checklist in the style of the TouchCells example from the Apple sample code. Basically, it is a table that allows multiple selection of its items and gives each selected item a check mark. The problem I'm having is that when I select an item and then scroll down the screen, another item (off the screen) will randomly be selected. It seems that it is usually the next cell to be loaded on the screen. I couldn't figure out what I was doing wrong so I tested it with Apple's TouchCells code. In their program though, they only have 6 cells and there is no room to scroll. So, I duplicated some of the items from the plist file to make more cells and... the same problem pops up. If you select a cell and then scroll, another cell will randomly be selected. Update I recently tried the iPhone Dev Cookbook sample code named "Checks" and... you guessed it, the same problem. Here's the link: http://code.google.com/p/cookbooksamples/downloads/list This is driving me nuts. Is it a bug or am I doing something wrong? Does anyone know how to fix this? Thanks! Also, does anyone know of any sample code that shows how to do this?

• NAMESPACE_SEPARATOR constant

  - by ts

  Hello, Having namespaces in PHP is great. Having '\' as namespace separator is a little bit ... awkward (but if there is someone who thinks that is cool & sexy, I am adding tag "rant" to this post. ;) . So, here goes the question: Are you using in your code NAMESPACE_SEPARATOR constant? As in code below: <?php if (!\defined('NAMESPACE_SEPARATOR') { \define('NAMESPACE_SEPARATOR', '\\'); } // if Pros: consistent with DIRECTORY_SEPARATOR (which all of us are using ;) no mess with escaping (think of '\Foo\Bar' but '\\' . Foo' . '\\' . 'Bar') more readable (IMHO) which gives us in effect an opportunity to write good, namespace-aware autoloaders can resist another change if something scary happens (as with ol'good '::' from PHP 6 alpha) can hide uniquess of '\' as namespace operator in programming language land from strangers ;) Cons: "The reason for DIRECTORY_SEPARATOR is that the value is platform dependent, the namespace separator isn't." (as stated in http://bugs.php.net/bug.php?id=43046) 19 characters instead of 1 ( \ ) or 4 ('\\') There are places where you can't use this (full qualified class names as default class variables) ie: class A { protected $sDefaultReporterClass = '\My\Namespace\DefaultReporter'; } So, what are you thinking ?

• Strange \n in base64 encoded string in Ruby

  - by intellidiot

  The inbuilt Base64 library in Ruby is adding some '\n's. I'm unable to find out the reason. For this special example: irb(main):001:0> require 'rubygems' => true irb(main):002:0> require 'base64' => true irb(main):003:0> str = "1110--ad6ca0b06e1fbeb7e6518a0418a73a6e04a67054" => "1110--ad6ca0b06e1fbeb7e6518a0418a73a6e04a67054" irb(main):004:0> Base64.encode64(str) => "MTExMC0tYWQ2Y2EwYjA2ZTFmYmViN2U2NTE4YTA0MThhNzNhNmUwNGE2NzA1\nNA==\n" The \n's are at the last and 6th position from end. The decoder (Base64.decode64) returns back the old string perfectly. Strange thing is, these \n's don't add any value to the encoded string. When I remove the newlines from the output string, the decoder decodes it again perfectly. irb(main):005:0> Base64.decode64(Base64.encode64(str).gsub("\n", '')) == str => true More of this, I used an another JS library to produce the base64 encoded output of the same input string, the output comes without the \n's. Is this a bug or anything else? Has anybody faced this issue before? FYI, $ ruby -v ruby 1.8.7 (2008-08-11 patchlevel 72) [i486-linux]

• NSString's stringByAppendingPathComponent: removes a '/' in http://

  - by Jasarien

  I've been modifying some code to work between Mac OS X and iPhone OS. I came across some code that was using NSURL's URLByAppendingPathComponent: (added in 10.6), which as some may know, isn't available in the iPhone SDK. My solution to make this code work between OS's is to use NSString *urlString = [myURL absoluteString]; urlString = [urlString stringByAppendingPathComponent:@"helloworld"]; myURL = [NSURL urlWithString:urlString]; The problem with this is that NSString's stringByAppendingPathComponent: seems to remove one of the /'s from the http:// part of the URL. Is this intended behaviour or a bug? Edit Ok, So I was a bit too quick in asking the question above. I re-read the documentation and it does say: Note that this method only works with file paths (not, for example, string representations of URLs) However, it doesn't give any pointers in the right direction for what to do if you need to append a path component to a URL on the iPhone... I could always just do it manually, adding a /if necessary and the extra string, but I was looking to keep it as close to the original Mac OS X code as possible...

• Map large integer to a phrase

  - by Alexander Gladysh

  I have a large and "unique" integer (actually a SHA1 hash). I want (for no other reason than to have fun) to find an algorithm to convert that SHA1 hash to a (pseudo-)English phrase. The conversion should be reversible (i.e., knowing the algorithm, one must be able to convert the phrase back to SHA1 hash.) The possible usage of the generated phrase: the human readable version of Git commit ID, like a motto for a given program version (which is built from that commit). (As I said, this is "for fun". I don't claim that this is very practical — or be much more readable than the SHA1 itself.) A better algorithm would produce shorter, more natural-looking, more unique phrases. The phrase need not make sense. I would even settle for a whole paragraph of nonsense. (Though quality — englishness — of a paragraph should probably be better than for a mere phrase.) A variation: it is OK if I will be able to work only with a part of hash. Say, first six digits is OK. Possible approach: In the past I've attempted to build a probability table (of words), and generate phrases as Markov chains, seeding the generator (picking branches from probability tree), according to the bits I read from the SHA. This was not very successful, the resulting phrases were too long and ugly. I'm not sure if this was a bug, or the general flaw in the algorithm, since I had to abandon it early enough. Now I'm thinking about attempting to solve the problem once again. Any advice on how to approach this? Do you think Markov chain approach can work here? Something else?

• How can I find out what is stopping my object from disposing properly?

  - by SLC

  I have a rather large and complex game in C#, and in it are various monsters. The monsters are created in the game by a MonsterCreator, and each monster has various plugins that are loaded from external DLLs. When my monsters die, they call a method in the MonsterCreator, and the MonsterCreator removes them from the game map, removes them from its own internal list of monsters, and then finally calls the Dispose() method on the monster itself. The dispose method calls the dispose method of each plugin, then clears up any of its own code. This seems to work fine, with lots of monsters, but somewhere there is a bug that crops up after a while, where a monster dies, but it has already been removed - it seems the callback telling the MonsterCreator is being called over and over, when the monster should have been removed on the first call. The likely candidate is that some of the plugins for the monster register themselves with an Event that pulses them every X number of seconds so they can perform logic. Stepping through I can see that they are unregistering with the Event when they die, but something is getting through still and I don't know what it is. Do you have any advice for debugging the problem? I can't post code really because it's split across a ton of libraries and plugin dlls, so it's more a case of figuring out the best way to debug it. I threw an exception in code when the monster died callback method is thrown and the monster cannot be found on the map to be removed, so I have the misbehaviing Monster, is there a way I can see what is still linked to it?
