• How can I get full filenames from Git difftool (for Microsoft Word "Compare Documents" feature)?

  - by Doug

  I am using the latest version of Git (1.6.6) on a Mac. My wife wants to use Git to manage her fiction writing as long as she can still use Microsoft Word 2008 (Mac). Instead of pushing her into saving everything as plain text, I would like to use Git Difftool to pass the files to Word and use Word's Compare Documents feature. She wouldn't be able to use Git Diff since Word docs are binary files but she could still use Git Difftool. I have written an Applescript which takes two filenames in this format: /Users/foo/Documents/my_novel.docx and opens Word to do the file comparison. However, Git Difftool seems to only pass the bare filenames (e.g. my_novel.docx) as parameters. Is there anyway to get the full filenames from Git Difftool? Thanks, Doug

• How to update model?

  - by Alexander Efimov

  Hi, guys. I have an ASP.NET MVC page where the model is being edited. On each action executing I have a new controller, so I don't get an updated model. I'm saving a model instance into Session["MyModelKey"]. But every time an action is executed, I have unmodified instance there even if I have changed values in textboxes which were created like this: @Html.LabelFor(model = model.EMail) @Html.TextBoxFor(model = model.EMail) @Html.LabelFor(model = model.Country) @Html.TextBoxFor(model = model.Country) @Html.ActionLink("MyAction", "MyController") Controller: public class MyController : Controller { public ActionResult MyAction() { //Every time this action is executed - I have a new controller instance //So I have null in View.Model //I get Session["MyModelKey"] here, //But the model instance properties are not updated //even though I have updated E-mail and Country properties of the model in the UI } } So, how can I get an updated model? Thanks in advance.

• Dolphin Smalltalk - adding method

  - by bialpio

  Hi, I am trying to create a custom class in Dolphin Smalltalk. When I open the Workspace, type in and evaluate the code: Object subclass: #Sudoku instanceVariableNames: 'board' classVariableNames: '' poolDictionaries: '' category: 'JiPP SudokuSolver'. everything works fine and the class is created and visible from Class Browser. The problem is, I want to add custom member method to this class, but without using Class Browser. Is it possible from the Workspace? I want to have one file with all the source code, so I don't have to worry about saving entire image.

• Silverlight - Binding ImageSource to Rectangle Fill

  - by Matt.M

  Blend 4 is telling me this is invalid markup and its not telling me why: <ImageBrush Stretch="Fill" ImageSource="{Binding Avatar, Mode=OneWay}"/> I'm pulling data from a Twitter feed, saving to an ImageSource, and then binding it to an ImageBrush(as seen below) to be used as the Fill for a Rectangle. Here is more context: <Rectangle x:Name="Avatar" RadiusY="9" RadiusX="9" Width="45" Height="45" VerticalAlignment="Center" HorizontalAlignment="Center" > <Rectangle.Fill> <ImageBrush Stretch="Fill" ImageSource="{Binding Avatar, Mode=OneWay}"/> </Rectangle.Fill> </Rectangle> I'm using this inside of a Silverlight UserControl, which is used inside of a Silverlight Application. Any Ideas on what the problem could be?

• Java OpenGL color material darkens when depth test is disabled

  - by Jeff Storey

  I've been working with the depth buffer in OpenGL (JOGL) to ensure certain items are rendered in front of others by disabling the depth buffer (detailed in my previous question http://stackoverflow.com/questions/2516086/java-opengl-saving-depth-buffer). This works, except when I set the color of an item that is being drawn when the depth test is disabled, none of the material shininess shows up. The item is rendered as a darker version of the original color (it seems like there is no lighting effect really applied to it). Is there a reason why this would be happening? and how might I prevent this? thanks, Jeff

• Developing FIrebug like web application for CSS things.

  - by vishwanath

  I am developing a web application for web designing. One part of it includes changing CSS styles on the run and saving the same back to server. I see that, first part of my motive is implemented there in firebug, where I can view CSS style rules applied to a particular HTML element and can change them to view the effect. An earlier question at SO lead to me firebug lite source code https://getfirebug.com/firebug-lite-debug.js , which is far less confusing than full version of firebug. My question was that, is there any way I can get documentation of the firebug/firebug lite code which can speed things up for me. After some googling I found out that there is Firebug API http://getfirebug.com/developer/api/firebug1.6/ But don't know how much useful it is for me. Any alternative way to do this is also welcome.

• Asynchronous operations performance

  - by LicenseQ

  One of the features of asynchronous programming in .NET is saving threads during long running operation execution. The FileStream class can be setup to allow asynchronous operations, that allows running (e.g.) a copy operation without virtually using any threads. To my surprise, I found that running asynchronous stream copy performs not only slower, but also uses more processing power than synchronous stream copy equivalent. Is there any benchmark tests were done to compare a synchronous vs asynchronous operation execution (file, network, etc.)? Does it really make sense to perform an asynchronous operation instead of spanning separate thread and perform synchronous operation in server environment if the asynchronous operation is times slower than the synchronous one?

• What is your motivation?

  - by vava

  As software developers we all know that motivation matters. Without it we could just stare into the monitor all day long and do nothing. There are some tricks to get yourself motivated like talking to people or doing the fun part of the project, but they do not always work. In the mean time I started to notice that I am most productive when I could see the person who is appreciating my work. The user, who is using the software and enjoying it. Because if there's none, what's the point of writing this code? So I was wondering, what makes you be at your top, is it the users, your fellow coders or maybe the money you get? PS. I know there's quite a few questions about motivation but they all about overcoming current situation. What I want to hear is what makes you come to the office every day, what you enjoy the most in your job, what makes you want to write this code and do it as fast as you possible could.

• Why does GetSqlDecimal throw when GetDecimal doesn't?

  - by I. J. Kennedy

  I have a database table that has a column of type money, allowing nulls. Using a SqlDataReader named reader, I can do decimal d = reader.GetDecimal(1); which works, unless of course we're reading a null. If I try using SqlDecimal instead--and I thought the whole point of the SqlTypes was to deal with nulls--then I get an invalid cast, whether or not the value is null. SqlDecimal s = reader.GetSqlDecimal(1); // throws an invalid cast exception What am I doing wrong? Do I really have to write a conditional statement to shepherd the value from the database to a SqlDecimal variable?

• iPhone SDK Smaller CAF files: lower recording quality with Audio Queues?

  - by Nick

  In my iPhone app I have voice recording functionality the utilizes Audio Queue voice recording functions of the SDK. I'm saving directly to CAF format and using the following settings for the AudioStreamBasicDescription reference: audioFormat.mFormatID = kAudioFormatLinearPCM; I can see that there are other format ids I could use like: kAudioFormatLinearPCM kAudioFormatAppleLossless kAudioFormatAppleIMA4 kAudioFormatiLBC kAudioFormatULaw kAudioFormatALaw My knowledge of sound formats is very limited so my question is... which of these should I use to create the lowest compressed audio recording files? Plus, are there other settings I should apply to lower the quality and filesize even further?

• Tool to aid Code Review

  - by Prakash

  For our small team of 20 developers, we used do code review like: Make a label in svn and publish the label to the reviewers Reviewers checkout the code and add comments in line (with marker like: // REVIEWER_NAME::REVIEW COMMENT:) After all comments are in, reviewer checks in the code, preferably with new label. Developer checks the comments and makes changes (if appropriate) Developer keeps an excel sheet report for considered changes and reasons for ignored comments Problem: Developer needs to keep track of multiple labels which might have same comments Sometimes we even do One on One review and if we really have time, even do Table review (team of reviewers looks at the code on projector, on the fly, and pass comment) I was wondering: Are you guys using any specific tool which helps to do code reviews smoother? I have heard of Code Collaborator. But have anyone used that? Is it worth the money?

• <100% Test coverage - best practices in selecting test areas

  - by Paul Nathan

  Suppose you're working on a project and the time/money budget does not allow 100% coverage of all code/paths. It then follows that some critical subset of your code needs to be tested. Clearly a 'gut-check' approach can be used to test the system, where intuition and manual analysis can produce some sort of test coverage that will be 'ok'. However, I'm presuming that there are best practices/approaches/processes that identify critical elements up to some threshold and let you focus your test elements on those blocks. For example, one popular process for identifying failures in manufacturing is Failure Mode and Effects Analysis. I'm looking for a process(es) to identify critical testing blocks in software.

• Aaron Hillegass Chapter 18 Challenge Question

  - by jasonbogd

  I am working through Aaron Hillegass' Cocoa Programming for Mac OS X and am doing the challenge for Chapter 18. Basically, the challenge is to write an app that can draw ovals using your mouse, and then additionally, add saving/loading and undo support. I'm trying to think of a good class design for this app that follows MVC. Here's what I had in mind: Have a NSView-subclass that represents an oval (say JBOval) that I can use to easily draw an oval. Have a main view (JBDrawingView) that holds JBOvals and draws them. The thing is that I wasn't sure how to add archiving. Should I archive each JBOval? I think this would work, but archiving an NSView doesn't seem very efficient. Any ideas on a better class design? Thanks.

• egg git interface for emacs, commit message empty

  - by Gauthier

  I'm using egg (emacs got git) as git interface in emacs. Whenever I try to achieve a commit --amend, I receive a "GIT-COMMIT-AMEND> Aborting commit due to empty commit message". This is what i do: C-u C-x v c Then the commit buffer appears, with the message of my previous commit. Then upon C-c C-c I get the message stated above: empty commit message. I think I've had this behaviour with regular commits (as in not amend) before, but can't remember or find how I solved it. I tried editing the message (adding a space somewhere). No work. I tried saving the buffer before committing, that wouldn't work either (since C-c C-c is not active in another buffer than the commit buffer). Any clue?

• High volume SVM (machine learning) system

  - by flyingcrab

  I working on a possible machine learning project that would be expected to do high speed computations for machine learning using SVM (support vector machines) and possibly some ANN. I'm resonably comfortable working on matlab with these, but primarly in small datasets, just for experimentation. I'm wondering if this matlab based approach will scale? or should i be looking into something else? C++ / gpu based computing? java wrapping of the matlab code and pushing it onto app engine? Incidentally, there seems to be a lot fo literature on GPUs, but not much on how useful they are on machine learning applications using matlab, & the cheapest CUDA enlabled GPU money can buy? is it even worth the trouble?

• Good example usage of get_or _create in Django views and raising a Form error

  - by Rik Wade

  I would like to use get_or_create to check whether an object already exists in my database. If it does not, then it will be created. If it does exist, then I will not create the new object, but need to raise a form error to inform the user that they need to enter different data (for example, a different username). The view contains: p, created = Person.objects.get_or_create( email = registration_form.cleaned_data['email'], defaults = { 'creationDate': datetime.datetime.now(), 'dateOfBirth': datetime.date(1970,1,1) }) So 'p' will contain the existing Person if it exists, or the new Person if not. I would like to act on the boolean value in 'created' in order to skip over saving the Person and re-display the registration_form and raise an appropriate form validation error. The alternative I'm considering is doing a check in a custom Form validation method to see whether a Person exists with the data in the provided 'email' field, and just raising a validation error.

• silverlight 3.0 communication with winforms

  - by abusemind

  I would like to create a winform on the client side for interaction with Silverlight 3.0. The basic idea is using the winform browser. I definitely need both the directions of communication. Would it be impossible by using JavaScript as a midware for the interaction or some better ways? Or is there any new features of Silverlight 3.0 supported for this kind of winform application communication? The original one is one the client's browser to run but now I would like to migrate it to the winform application. For the sake of time-saving, please don't mention about the WPF because of the gap between WPF and the Silverlight.

• Silverlight 4 RichTextBox - can't restore Xaml with text containing curly braces

  - by fuzzyman

  We have a Silverlight application using the RichTextBox as a rich text editor for the user to create emails. We actually have our own serializer but essentially we are saving and restoring the Xaml. As far as I can tell it is impossible to restore any text containing curly braces. You can demonstrate this fairly easily by creating a RichTextBox and typing something similar to "{weird}" into it. Then take the .Xaml property of the textbox and set it on the .Xaml property of another textbox - kablooie. As we have our own serializer I have tried escaping the Text member of the Run elements with "". This makes no difference. I've tried replacing the braces with &#123; but that doesn't work either.

• Open source and salary

  - by darko petreski

  Hi, We are facing a lot of open source software. But someone needs to write that software. How are they payed? Do you know a good article about the open source politics and economy? Sometimes the big companies themselves release open source because they have some benefits. Then they sell support, advices ... My question is what is the real economy about open software? No professional will work for nothing. This software are couple of classes but thousand or may be millions of classes. If you are really a pro you will write software for money, because you have life, wife, kids, taxes, you must earn. Please do not tell me that they are doing this for pleasure or hobby. Regards, Darko Peterski Regards

• Core data and special characters (UTF-8)

  - by MW

  I have an iPhone application using Core Data with an SQLite database in the bottom. I'm writing some text content from the database to a file, but special characters such as Å, Ä and Ö are corrupted in the file (they show up just fine in the application). When creating and inserting data, I am not using any special encoding. I'm just taking the NSString (entered by the user in a UITextField) and putting it in my persistent objects. When saving the file, I use the following code: [csvString writeToFile:filePath atomically:YES encoding:NSUTF8StringEncoding error:&error]; I tried adding a BOM to the beginning of the text ("\xef\xbb\xbf") but it is still corrupted. Anyone has any ideas where the problem might be? Examples of corrupted characters: å becomes ö, ä becomes ä

• Remote iPhone / xCode application development?

  - by ANE

  4 java developers are new to iPod Touch/iPhone app development. They have an idea for an app. They have never used Xcode or Macs before. Instead of spending money for a new iMac or Mac Mini for each of them, my boss would like to sell them a $999 Apple server, hosted at a facility connected a single T1 line, and have all 4 people work remotely in Xcode. Is this feasible? Is anyone doing anything like this? Specifically, is 1 T1 enough for realistic remote app development? Would they have to work in black & white via Logmein or Gotomeeting to get decent speed? Can four people work remotely together on an Xcode project at the same time? Do they absolutely need their own Macs to connect their iPod Touches or iPhones physically to, or can they connect to their existing PCs with iTunes and install their in-development apps that way?

• How to Edit NSF file using c#?

  - by Preeti

  Hi, I want to programaticaly change some values to NSF item and then want to save it.(i.e to edit NSF File and then save the editions) for example: I want to set Sender name of all mails to "[email protected]".(Using Domino.dll). Solution I tried: (Swaping of To and From values) String Temp_From = ((object[])docInbox.GetItemValue("From"))[0] as String; String Temp_SendTo = ((object[])docInbox.GetItemValue("SendTo"))[0] as String; docInbox.ReplaceItemValue("From", Temp_SendTo); docInbox.ReplaceItemValue("SendTo", Temp_From); docInbox.Save(true, false, false); /* Applied for following fields also: For From: AltFrom,DisplayFrom,DisplayFrom_2,dspFrom,ForwardedFrom,INetFrom,tmpDisplayFrom For To : displaySendTo,EnterSendTo,Envelope_to,tmpDisplaySendTo Also Tried for saving : docInbox.Save(true, true, true); */ In above code after successful editing changes values are not reflected in Nsf File. But when i am reading edited Nsf (copying modified file on different location ) file programatically it is showing changed values.(Why changes are not visible here ?)

• Using Bitmap.LockBits and Marshal.Copy in IronPython not changing image as expected

  - by Leonard H Martin

  Hi all, I have written the following IronPython code: import clr clr.AddReference("System.Drawing") from System import * from System.Drawing import * from System.Drawing.Imaging import * originalImage = Bitmap("Test.bmp") def RedTint(bitmap): bmData = bitmap.LockBits(Rectangle(0, 0, bitmap.Width, bitmap.Height), ImageLockMode.ReadWrite, PixelFormat.Format24bppRgb) ptr = bmData.Scan0 bytes = bmData.Stride * bitmap.Height rgbValues = Array.CreateInstance(Byte, bytes) Runtime.InteropServices.Marshal.Copy(ptr, rgbValues, 0, bytes) for i in rgbValues[::3]: i = 255 Runtime.InteropServices.Marshal.Copy(rgbValues, 0, ptr, bytes) bitmap.UnlockBits(bmData) return bitmap newPic = RedTint(originalImage) newPic.Save("New.bmp") Which is my interpretation of this MSDN code sample: http://msdn.microsoft.com/en-us/library/5ey6h79d.aspx except that I am saving the altered bitmap instead of displaying it in a Form. The code runs, however the newly saved bitmap is an exact copy of the original image with no sign of any changes having occurred (it's supposed to create a red tint). Could anyone advise what's wrong with my code? The image I'm using is simply a 24bpp bitmap I created in Paint (it's just a big white rectangle!), using IronPython 2.6 and on Windows 7 (x64) with .Net Framework 3.5 SP1 installed.

• Custom ValidationAttribute test against whole model

  - by griegs

  I know this is probably not possible but let's say I have a model with two properties. I write a ValidationAttribute for one of the properties. Can that VA look at the other property and make a decision? So; public class QuickQuote { public String state { get; set; } [MyRequiredValidator(ErrorMessage = "Error msg")] public String familyType { get; set; } So in the above example, can the validator test to see what's in the "state" property and take that into consideration when validating "familyType"? I know I can probably save the object to the session but would like to avoid any saving of state if possible.
