• Is there a way to create a python object that will be not sortable?

  - by Graf

  Is there a possibility to create any python object that will be not sortable? So that will be an exception when trying to sort a list of that objects? I created a very simple class, didn't define any comparison methods, but still instances of this class are comparable and thus sortable. Maybe, my class inherits comparison methods from somewhere. But I don't want this behaviour.

• Rhino Mocks - Do we really need stubs?

  - by Marcelo Oliveira

  If it's possible to change mock behaviour in Rhino Mocks using mock.Stub().Return(), why do we need Stubs anyway? What do we lose by always using MockRepository.GenerateMock()? One big benefit of using Mocks instead of Stubs is that we will be able to reuse the same instance among all the tests keeping them cleaner and straightforward. The moq framework works in a similar way... we don't have different objects for mocks and stubs. (please, don't answer with a link to Fowler's "Mocks aren't stubs" article)

• The Silverlight 3 Toolkit styles prevent the displaying of SL 3.0 data validation errors.

  - by RayMartinsHair

  Hi, If I apply a style from the SL 3.0 Toolkit to my application the built in SL 3.0 data validation errors are not displayed on the application edit forms. If I removed the code that applies the toolkit style to the application the SL 3.0 data validation errors appear as per normal SL 3.0 behaviour? Has anyone else come across this problem????? Any help is always appreciated. Cheers Adam

• Java Data Structure

  - by Joe

  Hi there, I'm looking for a data structure that will act like a Queue so that I can hava First In First Out behaviour, but ideally I would also be able to see if an element exists in that Queue in constant time as you can do with a HashMap, rather than the linear time that you get with a LinkedList. I thought a LinkedHashMap might do the job, but although I could make an iterator and just take and then remove the first element of the iteration to produce a sort of poll() method, I'm wondering if there is a better way. Many thanks in advance

• Memory Allocation increases in didSelectRowAtIndexPath

  - by mongeta

  Hello, I'm testing my App and in a very simple view, each time a tap on a UITableView row, my allocation overall bytes get higher and higher and never go downs. I don't have any special code there, so I created a new project from scratch with a very simple view, force one section and just three rows. In the didSelectRowAtIndexPath code do nothing, and fire it with instruments and memory allocation and, the memory goes up with every cell selection ... Is this normal behaviour ? thanks, regards, m.

• Adding item to taxonomy menu vocabulary in the create content form?

  - by HorusKol

  I've implemented taxonomy menu in Drupal, and trying to set it up so that it is pretty easy for the user to add new items to the vocabulary from the create content form instead of having to administer the vocabulary itself. So far, all I can manage is the default behaviour of displaying the existing items.

• ReSharper no longer runs unit tests

  - by Ed Woodcock

  Hey folks I'm trying to write some unit tests for an app I work on at work (In the vague hope that others might follow suit), and I was originally running these tests using NUnit and the ReSharper plugin. However, ReSharper will no longer run tests for me for some reason: It simply crosses them out with a red strikeout. There's no error code I'm afraid, and there's no mention of such behaviour on the JetBrains site. Has anyone else experienced similar benhaviour? Cheers, Ed

• qx.ui.table.Table hangs my browser...

  - by W55tKQbuRu28Q4xv

  Hi all, I have a strange bug. I create a qx.ui.table.Table and if not all specified columns fit into window (horizontal scroll appear) my browsers (firefox 3.5.6 and chrome 5.0.344) hangs. If i just set width for window large (e.g. from 600px to 800px) - all works fine. May be I'm doing something wrong? Or how can I fix/avoid this 'strange' behaviour?

• Why does file have to be saved prior to running ?

  - by ldigas

  In MATLAB, why does the file have to be saved prior to running ? I often try quick snippets of code, which I could also easily run also on the Command Window line by line. So, why when I run them through the editor, I have to save them first ? Can this behaviour be changed, maybe ?

  In-process HSQLDB database are not expected to be opened by others, even for file-based storage. The documentation hints that this is possible: Server Modes, Advanced Topics, but I've not yet found a URL for how to activate this behaviour. Did anyone do this so they can share how to?

  I've been going through a Haskell tutorial recently and noticed this behaviour when trying some simple Haskell expressions in the interactive ghci shell: Prelude> 1.1 + 1.1 == 2.2 True Prelude> 1.1 + 1.1 + 1.1 == 3.3 False Prelude> 1.1 + 1.1 + 1.1 > 3.3 True Prelude> 1.1 + 1.1 + 1.1 3.3000000000000003 Does anybody know why that is?

• Restore file's modification time in git

  - by rampion

  I understand the default git behaviour of updating the modification time every time it changes a file, but there are times when I want to restore a file's original modification time. Is there a way I can tell git to do this? (As an example, when working on a large project, I made some changes to configure.ac, found out that autotools doesn't work on my system, and wanted to restore configure.ac's to its original contents and modification time so that make doesn't try to update configure with my broken autotools).

• Managing conflicting ivy repositories (in eclipse)

  - by Stephen

  I've got eclipse workspaces for my full time job and my home test work that are both set up with ivy (and using ivyDE). However, I'm finding that I'm getting strange behaviour and conflicts between the different workspaces - issues like not being able to find certain dependencies, or not compiling etc. Is there a way in ivy or ivyDE to set the home .ivy2 directory so that I can split my workspaces? At the moment, I'm alternating different directories for my .ivy2 cache.

• Java do while, while

  - by Pindatjuh

  Hello, what behaviour can I expect when I run this code: do while(testA) { // do stuff } while(testB); Will it behave like: do { while(testA) { // do stuff } } while(testB); Or: if(testA) { do { // do stuff } while(testA && testB); } Or something totally unexpected? I ask this question because I think this is quite ambiguous, and for other people searching on this topic, not because I am lazy to test it out.

• typeof for html plugin elements

  - by gf

  When using ECMAScripts typeof on plugin elements (i.e. embed or object), Safari & FireFox return "function": typeof(window.document['myPlugin']) // "function" This can't be influenced on the plugin side, as the browser doesn't call the plugin here. Funny enough, in IE the same line evaluates to "object". Is that simply implementation dependent behaviour as per ECMAScript §11.4.3 or am i missing something here?

• How to stop C# compile on first error in VS 2010?

  - by Ben Robbins

  At work we have a C# solution with over 80 projects. Is it possible in VS 2010 to stop compilation as soon as an error is encountered rather than the default behaviour which is to continue as far as possible and display a list of errors in the error window?

• Is it ok to perform DB operation on UI thread?

  - by user648462

  I am using a database to persist the state of a search form. I am using the onPause method to persist the data and the onResume method to restore it. My opinion is that restoring and persisting state should be a blocking operation so I plan to perform the database operations on the UI thread. I know this is generally discouraged but the operations should be quick and I think if they were done asynchronously they could lead to inconsistent UI behaviour. Any advice

• What are possible causes of IDirect3DVertexBuffer9::Lock failing?

  - by Suma

  In error reports from some I have quite often seen following behaviour: IDirect3DVertexBuffer9::Lock fails, returned error code is D3DERR_NOTAVAILABLE. Once this happens, quite frequently (but not always) it is followed by CreateTexture or CreateVertexBuffer failing with error D3DERR_OUTOFVIDEOMEMORY. What are possible reasons for vertex buffer lock failure? Could virtual memory address space exhausted, or what?

I want when I move the slider to move a dot on the chart accordingly with the slider position. See attached screenshot: As you can see it seems to work fine. I've implemented this behaviour using the pathIntersection() method. On the slide event at each ui.value (x coordinate) I intersect my chartPath (the one from above) with a vertical straight line at the x coordinate. But still there are some problems. One of them is that it runs very hard, and it kinda freezes sometimes.. and very weird sometimes it doesn't seem to intersect at all even it should.. I'll example below 2 cases I identified: M 499.8461538461538 0 L 499.8461538461538 140 M 910 0 L 910 140 Could you please explain why this intersect behaviour happens (it should return a dot).. and the worst part it seems like it happens randomly.. if I use another chartdata. Also if you can identify another (better) solution to syncronise the slider position with the dot on the chart.. would be perfect. I thought about using Element.getPointAtLength(length), but I don't know how. I think I should save the pathSegments and for each to compute the start Length and the finish Length.
