LINQ query and IDisposable
I'm currently writing a piece of code that does some searches which returns IDisposable objects (DirectoryEntry to be specific from an ADAM instance) and I end up with code similar to using(var entry = (from result in results let entry = result.GetDirectoryEntry() where entry != null select entry).Last()) { //blah blah } but who is then responsible for Disposing the objects not returned by the above query? or more to the point is the above code actually missing a call to Dispose() for all other entries than the last?

How to destory Fragment?
I have a one Activity. Activity has 2 Fragment. Fragment A is Menu. Fragment B is Detail. I try to Make other Fragment C in Fragment B. so, There are 3 Fragment in Activity. And I try to Replace Fragment B to Fragment D. I guess Fragment B and C is dead. BUT these Fragments is alive. Just Fragments are onDestroyView() state. I want onDestroy() or onDetach(). What i to do for Fragments.onDestroy() or onDetach(). i can`t destroy or change the Activity.

What kind of DataStructures can enable parallel processing
Binary Tree: For example, if we need to process Tree datastructure parallely. We can spawn one thread to process left node, and another thread to process right node. Now both can independently run on the same data strucuture. It is certainly not possible to have same kind of parallelism for linked list. I am thinking, if there are any other data structures, that gives us the flexibility for acheiving parallelism similar to a binary tree ?

Delphi, Winhttp, Google Login, Fusion Tables
This is the continue of my previous question: http://stackoverflow.com/questions/6943626/delphi-webbrowser-google-login-fusiontable But the test with WinHTTP also failed as TWebBrowser based test... And this is one question as you wish... :-) I have one table what is NOW PUBLIC, but when we will buy non-free account it will be changed to private kind. I created a simple WinHTTP test, but this also failed. I can login, I got the "Auth" tag, but the next "private" request returns 401 error. procedure TForm1.BitBtn1Click(Sender: TObject); var WinHttpReq, temp : variant; URL, s : String; params : TStringList; authtoken, query, posts : string; begin URL := 'https://www.google.com/accounts/ClientLogin'; WinHttpReq := CreateOleObject('WinHttp.WinHttpRequest.5.1'); params := TStringList.Create; try params.Values['accountType'] := 'GOOGLE'; params.Values['Email'] := csEmail; params.Values['Passwd'] := csPwd; params.Values['service'] := 'fusiontables'; params.Values['source'] := csSource; posts := EncodeParamsToURL(params); finally params.Free; end; URL := URL + '?' + posts; WinHttpReq.Open('POST', URL, false); WinHttpReq.Send(); s := WinHttpReq.ResponseText; Memo1.Lines.Text := s; params := TStringList.Create; try params.Text := s; authtoken := params.Values['Auth']; Edit1.Text := authtoken; finally params.Free; end; //query := URLEncode('SHOW TABLES'); query := URLEncode('select * from 1236965'); url := 'http://www.google.com/fusiontables/api/query?sql=' + query; WinHttpReq.Open('POST', URL, false); WinHttpReq.setRequestHeader('Authorization', 'GoogleLogin auth="' + authToken + '"'); WinHttpReq.Send(); s := WinHttpReq.ResponseText; Memo1.Lines.Text := s; end; When I made "select", I got the rows. But when I want to see the tablenames, I get 401 error... I'm not sure what cause this error. a.) The free account don't have enough rights to access it privately b.) I set the header wrong c.)

How to plan your learning process efficiently?
I wonder is there a good strategy to use when you're about to start learning completely new stuff. For example, you want to learn LISP and you know nothing about functional programming and you've been always working with imperative languages, or you want to learn Aspect-Oriented programming and have no clue what's all about. There are usually plenty of books and tutorials on the subject but you aren't sure there most of them are of any good. So, how should you plan your learning process in order to get on the right track or to realize that isn't the right thing for you without wasting much time? Or how to grasp the essential concepts of a new technology? I'm pretty sure there are lot of people who would change the way they learned their first programming language. There are some questions which look like this one ([1][1],[2][2],[3][3]), but I think I'm trying to ask more general question here. [1]: http://stackoverflow.com/questions/19347/what-is-the-best-way-to-go-from-javac-to-c [2]: http://stackoverflow.com/questions/14599/aspnet-model-view-controller-mvc-where-do-i-start-from [3]: http://stackoverflow.com/questions/1576/what-should-a-longtime-windows-user-know-when-starting-to-use-linux

Using jQuery replace and regex to replace string
I'm currently using the .replace function to replace a specific string on the page. Given that I don't know where the current string is located so I can't select it, my code looks something like this: `$('body').html( $('body').html().replace(regex, 'sometext') );` So if the page originally looked like this: `<div class="a">Hello</div>` It now looks like this: `<div class="a">sometext</div>` Is there a way to do it without using `$('body').html( $('body').html().replace() )`? Thanks!

A very basic Haskell query
I've rather wondered into the world of Haskell with no prior background of anything to do with this. Reason being that I'm come across a puzzle that I'm trying to solve that seems to be based around haskell code. I believe that what I'm after is an integer. What I'm trying to do is the following let a = \x -> x (\y z -> (\y z -> (\y z -> (\y z -> (\y z -> (\y z -> (\y z -> (\y z -> (\y z -> (\y z -> (\y z -> (\y z -> y (y z)) (\x -> y (y (y (y (y (y (y x))))))) z) (\x -> y (y (y (y (y (y (y (y (y x))))))))) z) y (y z)) (\x -> y (y (y (y x)))) z) y (y z)) (\x -> y (y (y (y x)))) z) (\x -> y (y (y (y (y x))))) z) y (y z)) (\x -> y (y (y (y (y (y (y (y x)))))))) z) (\x -> y (y (y (y (y (y (y (y x)))))))) z) (\x -> y (y (y (y (y (y (y (y x)))))))) z) (\y z -> (\y z -> (\y z -> (\y z -> (\y z -> (\y z -> (\y z -> (\y z -> y (y z)) (\x -> y (y (y (y (y (y (y (y (y x))))))))) z) y (y z)) (\x -> y (y (y (y (y x))))) z) (\x -> y (y (y (y (y (y x)))))) z) y (y z)) (\x -> y (y x)) z) (\x -> y (y (y (y (y (y x)))))) z) a (1+) 0 This returns the following error message <interactive>:1:4: No instance for (Num (((t20 -> t20) -> t20 -> t20) -> (t20 -> t20) -> t20 -> t20)) arising from the literal `1' Possible fix: add an instance declaration for (Num (((t20 -> t20) -> t20 -> t20) -> (t20 -> t20) -> t20 -> t20)) In the first argument of `(+)', namely `1' In the first argument of `a', namely `(1 +)' In the expression: a (1 +) 0 <interactive>:1:8: No instance for (Num (t20 -> t20)) arising from the literal `0' Possible fix: add an instance declaration for (Num (t20 -> t20)) In the second argument of `a', namely `0' In the expression: a (1 +) 0 In an equation for `it': it = a (1 +) 0 Simple question - what do I need to do to make this work?

I Want Horizontal Scroll Bar When Window is Resize
I am an Electronic Engineer by profession but know some CSS and HTML.I manage a website http://www.sjpub.org which have a flash display. I notice that when the browser window is re-size, the text overflow across the picture and the flash display budge out from the display window because it can not be re-size. I want a situation where by when the window is re-size to a particular width (width of the flash display) or any arbitrary width, horizontal scroll-bar will appear to prevent the text from overflow and the flash display from budging out the window.I have tried several trick on CSS and read various post but the problem remain unsolved. I will be more than happy if I can get help from this forum. I can provide the CSS if requested or use Mozilla firebug. Thanks Sylvester

Has anyone heard that JQuery mobile is developing something to take the place of Phonegap?

What do you say to express the first succesful running of a program?
Yesterday, I had a moment of excitement when my LDAP client (pure C Win32) module successful retrieved data from Active Directory for the very first time. It was more than a smoke test -- I had all ready run a few of those, and it was well less than even feature complete code. Some data was mangled - so it wasn't even code I would show someone else. But it ran! It worked! (mostly) And now, I just have to massage it into shape. Saying "First data" sounds lame. An astronomer might refer to 'First light'. A shipbuilder might 'launch'. An ancient Greek philosopher might have had a bathtub moment. Is there such an expression for coding? What would you say?

Index safety when using C# indexers?
I'm coding a Vector class in C# and felt that indexers would be a good addition. Do I need to worry about the index being out of range? Perhaps a code sample would be clearer: class Vector3f { public Vector3f(float x, float y, float z) { this.X = x; this.Y = y; this.Z = z; } public float X {get; set;} public float Y {get; set;} public float Z {get; set;} public float this[int pos] { get { switch (pos) { case 0: return this.X; break; case 1: return this.Y; break; case 2: return this.Z; break; } } set { switch (pos) { case 0: this.X = value; break; case 1: this.Y = value; break; case 2: this.Z = value; break; } } } } Should I put a `default` case in my `switch` statements? What should it do?

ASP.NET, C#, IIS, Start Up
I am a total Noob to to .NET. I have all my files, folders, master pages, and code behind pages in my directory... I have been building it on a local development environment that was set up by the person who was here before me. I do not know much about what the specs of the environment are. I just tried transferring all of my files over to the server we will be running off of and I am getting a "500 - Internal server error"... I am thinking I am missing something real basic. What can I do with my Web.config file to get rid of this error and make the page viewable? I know the 500 error is very common and could mean alot of things, but just the most basic problem, what are you thinking? Thanks, Chris

Is adding lots of methods going to decrease performance?
I know that use a method instead of doing everything line after line is much more clear, so let's just put this assumption apart. I was asking myself if doing the same thing calling a method take more time (for the call to the method) or not, imagining that the bytecode generated is the same.

WHERE clause fails with certain string literals
I have a database table that stores error messages, and I want to run various queries on them. First, I get an overall count by grouping them like this: select MessageText, COUNT(*) from MessageLog group by MessageText And the result is: 1 Input string was not in a correct format 4 2 Value cannot be null. Parameter name: Int 8 3 Value cannot be null. Parameter name: String 1 Now, if I try to select messages by the text string, some of them return no results even though the messages exist. For example, select * from MessageLog where MessageText = 'Value cannot be null. Parameter name: Int' does not return any results, even though the previous query shows there are 8 of them. What is it about this string that fails to match?

Receiving error message: "The installed product does not match the installation source(s)"
I have written a .NET C# application and have created an installer in Visual Studio 2008. Everything works fine. The application uses an external config file (not app.config). The application is written such that when the config file is deleted, the defaults for the application are restored and a new config file is created. This behaviour is part of the requirements of the system and cannot be changed. When the file is deleted, however, the next attempt to run the application results in the following error message: "The installed product does not match the installation source(s)" And the system brings up an installer program. I'm figuring that there is some sort of configuration in the install project that can turn this behavior off, but I cannot find any documentation or parameters to change this behavior. Any ideas?

xforms outside a browser - specifically .NET WPF app
Looking for examples of rendering / filling out arbitrary forms defined by XForms (or some similar alternative) inside a WPF desktop app. Are there any .NET implementations of XForms (almost everything I can find is in Java or running in a web browser)? Is there are better way of defining forms for use in the .NET world?

How to export/download table from mysql database using C#?
I want to export a table from a mysql database to a txt or csv file like the way you can in phpmyadmin . I currently use the code below but after the program has been running for a few hours it will throw an "tried to read past the stream" error. MySqlConnection connection = new MySqlConnection(MyConString); MySqlCommand command = connection.CreateCommand(); connection.Open(); command.CommandText = "SELECT * FROM mytable"; MySqlDataReader result = command.ExecuteReader(); if (result != null) while (result.Read()) { string thisrow = ""; for (int i = 0; i < result.FieldCount; i++) thisrow += result.GetValue(i).ToString() + ","; pass = Regex.Replace(thisrow, @"\W*", ""); if (!hshTable.ContainsKey(pass)) hshTable.Add(pass, pass); } connection.Close(); is there a command like `myquerystring = "LOAD DATA LOCAL INFILE 'C:/mysqltable.txt' INTO TABLE mytable FIELDS TERMINATED BY ',' LINES TERMINATED BY '\n'";` that instead of loading a file to the database it downloads the table instead?

control on backtracking
Assume that backtracking is done as shown below. Each end point show success or fail. Ex: foo(X, search_key). Backtracking : Root / | \ / | \ / | \ /|\ | \ / | \ | /|\ / f f | / | \ / | f | f f g f Abbreviation f : fail g show first character of name Unless no other way is found, I will not prefer to use g as argument in my next function.However, in this example, since no other way is found, I must use g as an argument in my next function. How can I do that ?

Perl basic questions
1. In Unix shell script we check the exit of the previous command by checking the whether the value of $! equal to zero. How can i do it in perl. 2. when i do a perl -V i am able to see some paths listed in @INC. How do i add new paths to @INC. 3. In GetOptions function how can i set the order of argument. If i want -email to be in first argument. If it's given as second argument it should fail. GetOptions( 'nemail' => sub { $ENV{EMAIL} = "Y" } , 'arg' => \$help ); 4. What is the difference between .pl and .pm extension? When i need to use .pm extension? 5. when i use use File::Copy; where does the code is located. which enviromental variable does it when i have "use"

OPERATING SYSTEMS AND IN NEED OF ADVICES ABOUT THE ARM CONTROLLER
People say Operating system is the software that controls the hardware I dont understand what it really is. For instance We are writing a code for a calculator It takes control of the LCD and KEYPAD We write the code to bring the interface between LCD and KEYPAD But people dont call these as Operating system They say its a normal code. what really a Operating system mean I have tried it on google and everywhere They just say its a software that controls hardware Can anyone clear my doubt? and i want to make wonders in micro controllers I made some good tasks on 8051 I want to learn ARM But there are many versions to go through I dont know where to start ARM 7 or ARM 9 Can anyone give me some suggestion about these. And any good sites regarding the ARM 7 or ARM 9 to the beginners. And any free IDE to work on the ARM I dont know how to make the things I believe here leading experts are teamed up And give good advices And i know you do it again to me If you dont mind give me some link where i can download the ARM IDE and the TUTORIALS to beginners

How Do I Check How Much Credits My App Has Earned?
I just launched an app yesterday and made a test buy with my profile, but I am not very sure where to look to view my app earnings for this test buy. The closest I came was looking in: Apps >> MY APP NAME >> Insights >>Credits. but the the only information I see there is for SPEND, CHARGEBACKS, REFUNDS. Can anyone please tell me if this SPEND info/graph is the money my app has earned? And then the graph does not show the test purchase I made, assuming this SPEND info is my app earnings. so does it mean I did something wrong? Or does mean it takes a while before your earnings show up in your account profile, for it has been maybe some 7-9 hours since i made the best buy. Thanks all.

Will Learning C++ Help for Building Fast/No-Additional-Requirements Desktop Applications?
Will learning C++ help me build native applications with good speed? Will it help me as a programmer, and what are the other benefits? The reason why I want to learn C++ is because I'm disappointed with the UI performances of applications built on top of JVM and .NET. They feel slow, and start slow too. Of course, a really bad programmer can create a slower and sluggish application using C++ too, but I'm not considering that case. One of my favorite Windows utility application is [Launchy][1]. And in the Readme.pdf file, the author of the program wrote this: > 0.6 This is the first C++ release. As I became frustrated with C#’s large > .NET framework requirements and users > lack of desire to install it, I > decided to switch back to the faster > language. I totally agree with the author of Launchy about the .NET framework requirement or even a JRE requirement for desktop applications. Let alone the specific version of them. And some of the best and my favorite desktop applications don't need .NET or Java to run. They just run after installing. Are they mostly built using C++? Is C++ the only option for good and fast GUI based applications? And, I'm also very interested in hearing the other benefits of learning C++. [1]: http://launchy.net/

What is the best CI server for a PHP web application?
I had a look at [Travis CI](http://www.travis-ci.org) - which seems to be utterly complex to setup, [Jenkins](http://www.jenkins-ci.org) - with which I'm fairly familiar, but still seems a bit too much for some PHP development, and [Xinc](http://code.google.com/p/xinc) - which hasn't the SCM backend I need (Mercurial). Still, I haven't yet found the one CI server that hasn't any downside, so far my mind tends to go for Jenkins. Have I overseen anything important in the area? My requirements: - Checkout / update via Mercurial - Test runs on commit / scheduled - PHPUnit-compatible - Notifications via Mail (Jabber would be a plus) - Integration of Code Coverage results Thanks, Thomas.

Can this company claim ownership of my personal project?
I have been working on a project in my personal time that has nothing at all to do with my main job. I work on it after work, on the trolley to work, and on the trolley from work. I store all my source code in my own personal repository on my personal server in my apartment. While at work, I use the same computer which I purchased to do my main job. I do not ever work on my personal project at work. I have, however, pushed commits to my Mercurial repository over ssh (hg push ssh://hostname:22//path/to/repository) immediately after arriving at work, just so things were backed up. I also talked to one of my team members for under 5 minutes on a couple occasions about whether he would be interested in helping with the project on his own time, completely separate from his main work. My question is, could the company claim any ownership of the project? This is my last week at this company. Would it be worthwhile to have my boss sign something that says they agree to not claim any ownership of the project?

Would you make this method Static or not?
During a code review I presented a method quickly to the team that I had made static and one person agreed that there was no reason for it to not be static and a person disagreed saying that he would not make it static because it wasn't necessary and just to be on the safe side for future modifications and testing.

Would you make this method Static or not? === During a code review I presented a method quickly to the team that I had made static and one person agreed that there was no reason for it to not be static and a person disagreed saying that he would not make it static because it wasn't necessary and just to be on the safe side for future modifications and testing.

MongoDB, how to update a part of an array only?
I have a document in MongoDB which holds some meta info like the date updated and the _id, and an array of addresses. { "_id": { "$oid": "4e73a30466ca1a1f56000001" }, "updated": 1316215062, "address": [ { "street": "Rotenturmstrasse 8", "postcode": "1020", "phone": "Vienna", "altitude": -1, "geolocation": [ "11.367464", "47.204876" ] } ] } Now there could be multiple addresses. I am creating an object for an address which needs to be updated and saving it to the database. This is what the new object to be inserted looks like: new_object = { :_id=>BSON::ObjectId('4e73a30466ca1a1f56000001'), :updated=>1316215099, :address=>[ nil, nil, { :street=>"Reumannplatz 8", :postcode=>"1020", :phone=>"Vienna", :altitude=>-1, :geolocation=>[ "12.367464", "48.204876" ] } ] } Upon calling `db.venues.save(new_object)` what I would like the document to end up looking like is: { :_id=>BSON::ObjectId('4e73a30466ca1a1f56000001'), :updated=>1316215099, :address=>[ { "street": "Rotenturmstrasse 8", "postcode": "1020", "phone": "Vienna", "altitude": -1, "geolocation": [ "11.367464", "47.204876" ] }, nil, { :street=>"Reumannplatz 8", :postcode=>"1020", :phone=>"Vienna", :altitude=>-1, :geolocation=>[ "12.367464", "48.204876" ] } ] } Instead it overwrites the entire array and ends up like this: { :_id=>BSON::ObjectId('4e73a30466ca1a1f56000001'), :updated=>1316215099, :address=>[ nil, nil, { :street=>"Reumannplatz 8", :postcode=>"1020", :phone=>"Vienna", :altitude=>-1, :geolocation=>[ "12.367464", "48.204876" ] } ] } What's the way to do it? I am trying to avoid multiple queries. Would it make things easier if the address array in the database was a hash instead?

Position of Game AI in world
I have a question about controlling position of AI character in games. in most games animations of player are inplace so position of character is in our hands. but when look at AI animations, they are not in place. for example when an ai moves forward his animation moves one step in localspace. if we want to loop this animation, after one step character go back to first place. we need ai moves forward in the world. my question is : how to update position of ai character in world space? thanks.

Are BPM solutions worth the investment in money, time and effort?
This is more an architecture related question than a programming one, but I think it might be useful to developers given that I have been wondering this myself for some time. I have no experience with Business Process Management tools use or implementation. (The closest thing I have used is BizTalk server, but I know that it is not really a full BPM product, but a document based integration platform with some process orchestration features). Recently, several of our clients have been asking for BPM-based development projects, and most of the time I discover that some BPM vendor has been giving them some of those 'look how amazing is my product' demos, where they show 'how easily' you can modify your business process flow just by 'dragging and dropping' shapes around and those kind of things. Obviously, vendors don't say anything about **how you first need to have running your well designed processes on the BPM so you can actually make that kind of magic happen**. My clients suddenly see a new light thinking that BPM technology will finally fix the typical problems common to almost any IT department: applications that are hard to maintain, missing deadlines when implementing changes to support new business needs, etc. None of them have finished implementing BPM, so I have no a real world reference to know what is such think like. I honestly believe that many of those problems only should need solutions based on development process improvement, better analysis of future needs and better project management skills. Heck, even better programmers and designers. So, my question is: Is BPM really something that can deliver such great value to the typical enterprise line-of-business application and help having less maintenance problems and more flexibility? Or you are just acquiring yet another component that will suffer the same fate and problems as every other piece of software in your platform? In other words, what are BPM products good for? What should an organization have in place before trying to implement a BPM platform in order to succeed?

How do I perform a merge sort based on the property of an object (rather than an Array)?
##Background Using JavaScript, I need to sort a large JSON object based on a given property of that object. **I am assuming that a merge sort is the fastest approach**. If this is not the fastest approach, please tell me what is. There are myriad examples online of a merge sort against an array, but very little with objects. Here is a sample object: fruitForSale = { 1: {"type":"orange","UnitPrice":0.20}, 2: {"type":"banana","UnitPrice":0.30}, 3: {"type":"pear","UnitPrice":0.10}, 4: {"type":"apple","UnitPrice":0.50}, 5: {"type":"peach","UnitPrice":0.70} } ##Question Using a merge sort (or faster algorithm), how would I sort the `fruitForSale` object so that I end up with an object sorted by 'type': fruitForSale = { 4: {"type":"apple","UnitPrice":0.50}, 2: {"type":"banana","UnitPrice":0.30}, 1: {"type":"orange","UnitPrice":0.20}, 5: {"type":"peach","UnitPrice":0.70}, 3: {"type":"pear","UnitPrice":0.10} } NOTE: The original `keys` (1,2,3,4 & 5) would need to stay assigned to their respective object, so a key of `1` should always match with `{"type":"orange","UnitPrice":0.20}` and a key of `2` will always match with `{"type":"banana","UnitPrice":0.30}` and so on. Thanks!

Generate ASP.Net Membership Password Hash in Pure T-SQL
I'm attempting to create a pure t-sql representation of the default SHA-1 password hashing in the ASP.Net Membership system. Ideally, what I would get would be this: UserName Password GeneratedPassword cbehrens 34098kw4D+FKJ== 34098kw4D+FKJ== Note: that's bogus base-64 text there. I've got base64_encode and decode functions that round-trip correctly. Here's my attempt, which doesn't work: SELECT UserName, Password, dbo.base64_encode(HASHBYTES('SHA1', dbo.base64_decode(PasswordSalt) + 'testud01')) As TestPassword FROM aspnet_Users U JOIN aspnet_membership M ON U.UserID = M.UserID I've tried a number of variations on the theme, to no avail. I need to do this in pure T-Sql; involving a console app or something like that will double the work.

Often, people say that it doesn't scale well (citing Twitter as their prime example) -- but nobody actually explains ***why*** it doesn't scale well; and / or how to achieve the pros of AR without the cons (via a similar but different pattern?) Hopefully this won't turn into a holy war about design patterns -- all I want to know is ****specifically**** what's wrong with Active Record. If it doesn't scale well, why not?

How to use the ASP .NET AJAX Toolkit Tab with a Grid View inside
I have already search for some time over the net on how to create an ASP .NET AJAX toolkit tab control which uses GridView inside, could anyone point me on how to do this? Right now, our GUI team has already made a static tab control which is quite properly designed. I do not know how to use the tab with this. Any tutorial or link on using this combination could really help. I am already converting back the GUI to a MultiView simulated tab control because I do not know how to access the tab control. anyway, I am just worried i would destroy the GUI made by GUI team in this process. Thanks.

Selecting appropriate logic programming language
In my research I need to use a logic programming in Multiagent system simulation. I need to select a language and simulation/visualization environment for my experiment. I was thinking of using pyke (python based logic programming language) or Prolog/Mercury. But I have no idea how to visualize the system then. I have separately searched for MAS simulation software and found Netlogo, Mason, breve (can interpret python, so maybe pyke will do?) and others. Now I am confused with all this choices, so I wanted to ask if anyone has done anything similar and what can you suggest?

C - Freeing a pointer to pointer
In my code I allocate a number of 2-dimensional arrays that I need to free up. However, every time I think I've grasped the concept of pointers, they keep surprising me by not doing what I expect them to ;) So can anyone tell me how to deal with this situation?: This is how I allocate memory for my pointers: typedef struct HRTF_ { kiss_fft_cpx freqDataL[NFREQ] kiss_fft_cpx freqDataR[NFREQ] int nrSamples; char* fname; } HRTF; HRTF **_pHRTFs = NUL; int _nHRTFs = 512; _pHRTFs = (HRTF**) malloc( sizeof(HRTF*) *_nHRTFs ); int i = _nHRTFs; while( i > 0 ) _pHRTFs[--i] = (HRTF*) malloc( sizeof( HRTF ) ); // Load data into HRTF struct And here's how I think I should be freeing the used memory: if( _pHRTFs != NULL ) { __DEBUG( "Free mem used for HRTFs" ); for( i = 0; i < _nHRTFs; ++i ) { if( _pHRTFs[i] != NULL ) { char buf[64]; sprintf( buf, "Freeing mem for HRTF #%d", i ); __DEBUG( buf ); free( _pHRTFs[i] ); } } __DEBUG( "Free array containing HRTFs" ); free( _pHRTFs ); } Freeing the individual `_pHRTFs[i]`'s works, but the last `free( _pHRTFs )` gives me a segmentation fault. Why? Thanks in advance! Jonas

Moving data from several rows to columns in excel 2010 macosx
My problem is the following. I have an excel sheet with the content as follows: ---A--- ---B--- ---C--- ---D--- ---E--- ---F--- text1 text2 text3 text4 text5 text6 text7 text8 text9 text10 text11 text12 text13 text14 text15 text16 and so on... I want to move text5 and text6 to E and F for row1 and do the same for text11 and text12 in row 4 so the output looks as follows: ---A--- ---B--- ---C--- ---D--- ---E--- ---F--- text1 text2 text3 text4 text5 text6 text7 text8 text9 text10 text12 text13 text13 text14 text15 text16 text17 text18 i have tried to copy data referenced to a cell position but it only works when I copy each two cells, not for the whole. I have tried to traspose the data but that will traspose everything. any idea?

MySQL and PhpMyAdmin config.inc.php Password issue on MAMP
This is a very strange issue that is similar to a few other people issue that has been going on for a while with MAMP. I recently upgraded to MAMP2 and followed the instruction for the new phpMyAdmin and it work for a while but recently whenever I try to connect to MySQL I always get this error: Error: Could not connect to MySQL server! /Applications/MAMP/Library/bin/mysqlcheck: Got error: 1045: Access denied for user 'root'@'localhost' (using password: YES) when trying to connect So I changed the password to the correct one and changed all the files as per advised on this forum topic: http://forum.mamp.info/viewtopic.php?f=2&t=11974. But it did not work at all. I realized that there was two phpMyAdmin folder on my Mac one which is in /Applications/MAMP/Library/bin/phpMyAdmin and the other one in Library/Application Support/appsolute/MAMP PRO/phpMyAdmin In the first folder the config.inc.php as the correct credential for the user, however the second as root for both username and password. Obviously I tried to changed that but to no avail, the file is somehow always reverted to the default credential. Did someone ever had this issue? is there a way to solve this?

Alternative to MarkupExtension override in Silverlight
I'm using MarkupExtension inheritance in my WPF app, which I'd like to port under Silverlight. I've made a "Locale" markup extension which can be used like this in xaml <TextBlock Text="{ui:Locale aRandomId,'My default translation'}" /> In fact, this MarkupExtension is binding the property its applied on to the string "My default translation", or, if found, to a sentence stored in a database named "aRandomId". This MarkupExtension allows me to dynamicaly change my UI's locale (the markupextension is registering to a weak event 'LocaleChanged' which triggers update of every property bound with it) **As we cannot inherit from MarkupExtension in Silverlight, I'd like to know if there is some mechanism which could replace it.** Thanks. *PS : I can provide the source of this MarkupExtension if needed.*

How can i change the background color of a table cell with multiple sections?
I have a table view with multiple sections and don't know how to change the background color when i touch that row. I've found this link about table cells but it is addressed to tables with only one section : [changing cell background on click on cell in iphone][1]. cell.selectedBackgroundView = [[ UIView alloc] init]; [cell.selectedBackgroundView setBackgroundColor:[UIColor purpleColor]]; if i use the code from this link, cells that are rounded (the first and last in every section) will have a rectangle on finger over which doesn't look good. How can i make this rectangle curved around the edges for the first and last row in every section ? [1]: http://stackoverflow.com/questions/2598062/changing-cell-background-on-click-on-cell-in-iphone

I don't like MDD but like UML - why should I use MDD if I think this is useless ?
I am a java software developer/architect and I like UML. Saying that I also hate the java generated code. I don't see any value trying to generate the skeleton of my application because creating empty classes is really easy and I don't need a tool to do that. I also can't reuse the generated code because the way it is generated makes it impossible to reuse. The main problem for me is that my requirements changed so quickly that I need to be able to implement the new demand immediately into an existing code. My problem is that if I generate my code from my model and then manually code inside the generated code, I can't generate again a code using a model because my modification would be erased or if not I will have to manually copy each peace that has been added. Just an enormous job for few result. I therefore don't use anymore MDD but still use a lot UML. **My question is:** Could UML be successful in a project without this stupid MDD code generation ? I am asking this question because I have a new boss who wants to introduce full MDD process with IBM RSA and today I prefer to have live code and model synchronization or merge with Omondo. Why to change something that is working well ? Why to systematically generate code from a model while I can do it directly in the code and just merge it later with the model ? Why to get crap database code generation which can not even be deployed while I can add stereotype in order to get java annotation and use them with hibernate to generate my database. One of the reason for boss's change is to get a better project documentation in HTML format. I doubt of it and think he is looking ofr more control on delivery and don't know what to,invent !! Another reason is to use a large and stable company. Have a full model available which could be deployed in any other language. This is why for me MDD is stupid because it is impossible to deploy on any platform any server, any database just from a model. So why to waste my time ? Please give me some arguments in order to come back at next meeting and crash this stupid new MDD fan who wants to reorganize the way we work today !

One of the reason for boss's change is to get a better project documentation in HTML format. I doubt of it and think he is looking ofr more control on delivery and don't know what to,invent !! Another reason is to use a large and stable company. Have a full model available which could be deployed in any other language. This is why for me MDD is stupid because it is impossible to deploy on any platform any server, any database just from a model. So why to waste my time ? Please give me some arguments in order to come back at next meeting and crash this stupid new MDD fan who wants to reorganize the way we work today !

Add a custom button to a Django application's admin page
I have an application in Django with a routine which would be available only to the admin. I'm quite new to the python/django world, so maybe my question is trivial. What I want to do is add a button to perform the routine in this application's section of the admin app. I'm quite confused from there, am I suppose to make a template for it, and if it's the case, how do I add a html template for an app in the admin. Or maybe there's a command to simply add a button? Thanks for your time

Sorted output of a joined MySQL result in PHP
Doing an allnighter on a project and my mind is blank atm... Simple question really: I have two MySQL tables, product and category. Each product belongs to exactly one category. SELECT p.uid as product_uid, p.name_NL as product_name, p.price as product_price, c.uid as category_uid, c.name_NL as category_name FROM product p, category c WHERE p.category_uid = c.uid This gives me a nice overview of all products in their respective category. My question is about **outputting this data** on the page. I'm aiming for this: <h1>Category name</h1> <p>Product in this category</p> <p>Other product in this category</p> <h1>Next category</h1> <p>Product in next category</p> My mind is completely blank right now. How would one go about doing this? I would like to avoid doing subqueries (if possible). Kind regards, M

What are the best JPEG compression tools?
When making a webpage every byte counts. Especially if the webpage is heavy on graphics, has large backgrounds, etc. For that reason I want to find a good tool to compress my huge background files into as small JPEG files as possible, while still maintaining an acceptable quality. I know that a lot of things depend on the compression algorithms used, and "80% quality" can differ from tool to tool. For example, there are several tools aimed at recompressing PNG files as best as possible. Unfortunately I cannot find any good tools for JPEGs with Google, because there just is too much "noise" in the search results. Thus I turn to my fellow developers. What software do you know that maintans the best size/quality relation?

Especially if the webpage is heavy on graphics, has large backgrounds, etc. For that reason I want to find a good tool to compress my huge background files into as small JPEG files as possible, while still maintaining an acceptable quality. I know that a lot of things depend on the compression algorithms used, and "80% quality" can differ from tool to tool. For example, there are several tools aimed at recompressing PNG files as best as possible. Unfortunately I cannot find any good tools for JPEGs with Google, because there just is too much "noise" in the search results. Thus I turn to my fellow developers. What software do you know that maintans the best size/quality relation?

jQuery.ajax event not firing properly in IE8 (except when Fiddler is loaded)
This is possibly the weirdest error I've ever encountered: So I have a bundle of jQuery.ajax calls to a web service I threw together. It works great in Firefox and Chrome, but it does nothing in IE8 *unless* I have Fiddler running. (It's similar to the issue reported [here](http://stackoverflow.com/questions/1297673/jquery-ajax-not-working-remotely-on-ie), but I've tried the stuff mentioned to no avail.) In these non-functional calls, it seems like it's building the jqXHR object like it should, but something is missing. Not sure what, though - I'm not super-intimate with the inner workings of jQuery, so stepping through the call in the debugger can only do so much for me. Here's the call: $.ajaxSetup({ type: "POST", timeout: 30000, contentType: "application/json; charset=utf-8" }); $.ajax({ url: "/PSWS/UserManager.asmx/Login", data: '{"emailAddress":"' + myEmailAddress + '","password":"' + myPassword + '","stayLoggedIn":' + (myStayLoggedIn ? 'true' : 'false') + '}', success: function (response) { if (!response.Success) { alert(response.Message); } else { $(this).find('.message').remove(); $.fn.colorbox.close(); } }, dataType: 'json', error: function (jqXHR, textStatus, errorThrown) { $(this).find('.message').remove(); $(this).prepend('<div class="message message_error">Error!<br/>' + jqXHR.status + ' - ' + jqXHR.statusText + '</div>'); } });` I wondered if something was wrong in my JSON, either in what's sent or what's received. I don't know of a way to capture this except through Fiddler, but it seems to be valid. Valid enough for its parser and JSONLint, anyway. Sent: `{"emailAddress":"test@example.com","password":"asdasdasd","stayLoggedIn":true}` Received: `{"__type":"PSUserManagerService.SystemResponse","Success":false,"Message":"Error logging in: Invalid username and/or password.","Subscriptions":null}`

what is index and can non-clustered index be non-unique?
Subquestion to my question [1]: All definitions of (MS SQL Server) index (that I could find) are ambiguous and all explanations, based on it, narrate something without defining terms. What is the definition of index? For ex., the most common definition of index from wiki (http://en.wikipedia.org/wiki/Index_(database) ) : - 1) "A database index is a data structure that improves the speed of data retrieval operations on a database table at the cost of slower writes and increased storage space. Indexes can be created using one or more columns of a database table..." - 2) "SQL server creates a clustered index on a primary key by default[1]. The data is present in random order, but the logical ordering is specified by the index. The data rows may be randomly spread throughout the table. The non-clustered index tree contains the index keys in sorted order, with the leaf level of the index containing the pointer to the page and the row number in the data page" Well, it is ambiguous. One can understand under index: - 1) an ordered data structure, a tree, containing intermediate and leaf nodes; - 2) leaf node data containing values from indexed columns + "pointer to the page and the row number in the data page" Can non-clustered index be non-unique, considering 2)? or, even, 1) ? It doesn't seem so to me ... But does TSQL imply existence of non-unique non-clustered index? If yes, then What is understood by non-clustered index in "CREATE INDEX (Transact-SQL)"[2] and to what the argument UNIQUE is applied there? Is it: - 3) leaf node data containing values from indexed columns? i.e. like in 2) but without pointer + row number ) ? If it is 3), then again question 1) arises - why to apply constraints to copy of real data in "index", instead of real data in-situ? ---- [1] "UNIQUE argument for INDEX creation - what's for?" http://stackoverflow.com/questions/3799095/unique-argument-for-index-creation-whats-for [2] [CREATE INDEX (Transact-SQL)] http://msdn.microsoft.com/en-us/library/ms188783.aspx

Why does java have no byte type suffix?
So java has a long type suffix for literals: (123L), a double type suffix (43.21D), a floating point suffix (1.234F). So ... why no byte type suffix? For example, when writing some testing code you MUST cast all your bytes when they are used as function parameters. ByteBuffer b = ByteBuffer.allocate(100); b.put((byte)3); // super annoying b.put(3b); // if only It is clear that using B or b would not work since it would conflict with the ability to specify a byte in hexadecimal or octal (a critical language feature). But some other letter, like Z z? or Y y (for bYte)?

Why won't some jQuery code(s) work when isolated in unique <script> tags?
This question is not code specific. It is a very general question, prompted by something I've been observing while building this website, and it really puzzles me. In the head section of the site I'm working on, I have all the jQuery codes that run the site, enclosed within document ready methods, which are in turn enclosed within <script> tags in the head section of the site. I usually put each code that performs a unique function, within unique script tags. But I began to notice that some of my jQ codes wouldn't work at all when isolated in their own unique document ready method. Then when I transposed this same code to a neighboring document ready method containing another unrealated code which already works, the said code works fine. So the puzzle is, why wouldn't these codes work when isolated? Are there certain circumstances when this might be the case? Perhaps there is something fundamental about jQuery/javascript that i don't understand that's going on here. Has this been anyones's experience? Answers appreciated.
