• What's your favorite implementation of producing the fibonacci sequence?

  - by Terry Donaghe

  Best, most creative, most clever, fastest, smallest, written in weirdest language, etc etc. For those not familiar with this staple of programming exam question / interview question, check this out: Fibonacci Sequence at Wikipedia The question would be, write a simple program which will spit out the first n digits of the Fibonacci sequence. So, if n == 12, we produce: 0 1 1 2 3 5 8 13 21 34 55 89 144 Your implementation becomes more interesting when you set n to larger values. How long does it take your implementation to return a 25 digit sequence? How about 100?

• Querying a perimeter around a Geocode-Location (Lat/Lon)

  - by Tim

  Hi, how can I search for geo-objects in a certain perimeter ? E.g. I have several objects with Lat/Lon coordinates stored in my DB. Now I want to retrieve all the objects which lie in a specific perimeter (10 miles or 20 miles) around a given point. I guess what I would have to do is to form some query like: SELECT * FROM objects o where o.lat < (myPositionLat+x) AND o.lon < (myPositionLon+y) Is this right? How do I determine/set the values for x and y?

• Multi join query returns to many results and improperly matched

  - by Woot4Moo

  I have the following minimal schema in Oracle: http://sqlfiddle.com/#!4/c1ed0/14 The queries I have run yield too many results and this query: select cat.*, status.*, source.* from cats cat, status status, source source Left OUTER JOIN source source2 on source2.sourceid = 1 Right OUTER JOIN status status2 on status2.isStray =0 order by cat.name will yield incorrect results. What I am expecting is a table that looks like the following however I cannot seem to come up with the correct SQL. NAME AGE LENGTH STATUSID CATSOURCE ISSTRAY SOURCEID CATID Adam 1 25 null null null 1 2 Bill 5 1 null null null null null Charles 7 5 null null null null null Steve 12 15 1 1 1 1 1 In plain English what I am looking for is to return all known cats + their associated cat source + their cat status while retaining null values. The only information I will have is the source that I am curious about. I also only want the cats that have a status of either STRAY or UNKNOWN (null)

• ASP.net Usercontrol caching viewstate across users?

  - by Jason

  I have a usercontrol with asp:textbox controls on it that also performs postbacks. If two users, who are both identified by a different session variable, postback the page within the same second, one user will see the other user's viewstate values in the text boxes. I have validated that this happens by setting a textbox, a session variable, and a cookie to the same value (the same value that identifies the user) and writing to the log when all three don't match. The text box's value is the one that is logged as the other user's value. ASP.net 3.5, IIS 6 Has anyone experienced this issue.

• How to customise the TextView inside a Spinner?

  - by Janusz

  I have a Spinner with an ArrayAdapter that feeds Values into it. The Problem is that the text is to long for the view and the result is a very very ugly spinner. As can be seen in the screenshot: I tried to pass the Id of my own TextView into the Adapter but everytime the spinner should be shown I get an Exception that the Id I supplied is not valid: 04-26 17:38:39.695: ERROR/AndroidRuntime(4276): android.content.res.Resources$NotFoundException: Resource ID #0x7f09003a type #0x12 is not valid Where do I have to define the TextView? In a separate xml file? With a surrounding viewgroup? It would help me a lot if I could see an example of the adapter initialization and the textview definition?

• Remove adjacent identical elements in a Ruby Array?

  - by Mike Woodhouse

  Ruby 1.8.6 I have an array containing numerical values. I want to reduce it such that sequences of the same value are reduced to a single instance of that value. So I want a = [1, 1, 1, 2, 2, 3, 3, 3, 3, 2, 2, 2, 3, 3, 3] to reduce to [1, 2, 3, 2, 3] As you can see, Array#uniq won't work in this case. I have the following, which works: (a.size - 1).downto(1) { |i| a[i] = nil if a[i - 1] == a[i] } Can anyone come up with something less ugly?

• Is there any way to do a WER "Request Additional Files" for the windows temp directory?

  - by Jason Mathison

  My company has had numerous crashes reported to windows error reporting due to what looks like an install problem. The logs for our installs are typically in the windows\temp directory. I would like to include the install log file as a "Request Additional Files" entry, however there doesn't seem to be any way to get to a subdirectory of the list of environmental Variables that are provided. The windows temp directory is not in the list of values that you can work from, so I am stuck. In general, I don't understand how it is possible to get at almost anything of use via the "Request Additional Files". For example, the %programfiles% directory shouldn't contain any useful files, they should be in a subdirectory for your product. What am I missing?

• JTable - Getting a cell into Edit mode on pressing Tab

  - by Luhar

  This is possibly has a trivial solution, but I am at the end of my tether so I hope somebody can help out. I use a JTable which has a custom renderer and a custom editor for a set of columns. The renderer uses a JLabel component and the editor uses a JSpinner component. Our users want to be able to enter values in a column, and then press TAB or ENTER to move to the next editable cell in the table. If I understand correctly, this is the default behaviour for a JTable. However, this doesn't seem to work correctly for me. Until the user clicks on the cell, only the JLabel is displayed. The JSpinner (i.e. CellEditor) is only displayed when a user double clicks on the cell. So, it looks like the cell is going into "edit" mode only on MouseEvents, but not when it has focus. How do I get the cell to go into edit mode as soon as it has focus?

• Is there a Delphi standard function for escaping HTML?

  - by Mason Wheeler

  I've got a report that's supposed to take a grid control and produce HTML output. One of the columns in the grid can display any of a number of values, or <Any>. When this gets output to HTML, of course, it ends up blank. I could probably write up some routine to use StringReplace to turn that into &lt;Any&gt; so it would display this particular case correctly, but I figure there's probably one in the RTL somewhere that's already been tested and does it right. Anyone know where I could find it?

• Should I use parameters in template scripting to control the output, or a separate specialized template?

  - by asawyer

  Would it be considered best practice to use a single template that changes it's output based on script values, or have multiple templates, and use the view to pick the correct one instead? For example, in this underscope template: <script type="text/template" id="SkillsetTemplate"> <div class='RegularMode <%= (skillset.get('InEditMode')===false)?'show':'hide' %>'> </div> <div class='EditMode <%= (skillset.get('InEditMode')===true)?'show':'hide' %>'> </div> </script> I use a backbone model to bind against, and use the InEditMode attribute to pick which content to render. Should I instead have a normal mode, and an edit mode template, and use the attribute on the model to pick the template ? For background purposes, I am using backbone.js with underscore templates and an MVC3 backend.

• I'm looking for a constraint to prevent the insert of an empty string in MySQL

  - by Marga Keuvelaar

  Ok, in this question I learned how to prevent the insert of a NULL value. But, unfortunately, an empty string is being inserted anyway. Apart from preventing this on the PHP side, I'd like to use something like a database constraint to prevent this. Of course a check on the application side is necessary, but I'd like it to be on both sides. I am taught that whatever application is talking to your database, it should not be able to insert basically wrong data in it. So... CREATE TABLE IF NOT EXISTS tblFoo ( foo_id int(11) NOT NULL AUTO_INCREMENT, foo_test varchar(50) NOT NULL, PRIMARY KEY (foo_id) ); Would still allow me to do this insert: INSERT INTO tblFoo (foo_test) VALUES (''); Which I would like to prevent.

• building objects from xml file at runtime and intializing, in one pass?

  - by KaluSingh Gabbar

  I have to parse the XML file and build objects representation based on that, now once I get all these data I create entries in various database for these data objects. I have to do second pass over that for value as in the first pass all I could do is build the assets in various databases. and in second pass I get the values for all the data and put it in the database. I have a feeling that this can be done in a single pass but I just want to see what are your opinions. As I am just a student who started with professional work, experienced ppl please help. Can someone who have ideas or done similar work, please provide some light on the topic so that I can think over the possibility of the work and get the prototype going based on your suggestion. Thanks a lot for your precious time, I honestly appreciate it.

• Converting "User Shell Folders" registry value

  - by Sach

  The following registry key contains many system default folder locations. HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders The value for the path of the All Users desktop, which is found there, is as follows: XP or earlier : [%ALLUSERSPROFILE%\Desktop] Vista or later: [%PUBLIC%\Desktop] Whereas the actual paths of the All User desktops, respectively, are as follows: XP or earlier : "C:\Documents and Settings\All Users\Desktop" Vista or later: "C:\Users\Public\Desktop" Now, if you use copy and paste the above registry values in Windows Explorer and hit enter it takes you to the actual folders. For example, if you paste [%PUBLIC%\Desktop] in a Windows Explorer in Vista it takes you to ["C:\Users\Public\Desktop"]. My question is this; how do I reproduce this behavior from withing a C# program? To be more specific, if I retrieve the registry value [%PUBLIC%\Desktop] from withing a C# program, which I can do easily, how do I convert it to ["C:\Users\Public\Desktop"]? Obviously I'm not looking for a string replacement, I need to do what Windows does.

• jQuery-ajax call: async property is not working?

  - by user269386

  Hi, given to certain circumstances, I'm forced to keep page settings (Javascript-values) in the session and it has to be done right before leaving the page (I can't use cookies, since "pageSettings" can become quite large and localStorage is not an option yet ;) ). So this is how I tried it. However it seems that when I call the page directly again, the call of "http://blabla.com/bla" happens asynchronous, even though the async-attribute is set (I don't receive the settings of the previous call, but of the one before): $jQ(document).ready(function () { $jQ(window).unload(Main.__setSessionValues); }); var Main = { pageSettings: {}, __setSessionValues: function __setSessionValues() { $jQ.ajax({ type: "POST", async: false, url: "http://blabla.com/bla", data: { pageSettings: Object.toJSON(Main.pageSettings) } }); } }; Does anyone know what the problem might be? thanks in advance

• Operator() as a subscript (C++)

  I use operator() as a subscript operator this way: double CVector::operator() (int i) const { if (i >= 0 && i < this->size) return this->data[i]; else return 0; } double& CVector::operator() (int i) { return (this->data[i]); } It works when I get values, but I get an error when I try to write assign a value using a(i) = 1; UPD: Error text: Unhandled exception at 0x651cf54a (msvcr100d.dll) in CG.exe: 0xC0000005: Access violation reading location 0xccccccc0.

• erlang io:format, and a hanging web application

  - by williamstw

  While I'm learning a new language, I'll typically put lots of silly println's to see what values are where at specific times. It usually suffices because the languages typically have available a tostring equivalent. In trying that same approach with erlang, my webapp just "hangs" when there's a value attempted to be printed that's not a list. This happens when variable being printed is a tuple instead of a list. There's no error, exception, nothing... just doesn't respond. Now, I'm muddling through by being careful about what I'm writing out and as I learn more, things are getting better. But I wonder, is there a way to more reliably to [blindly] print a value to stdout? Thanks, --tim

• Correct syntax for matching a string inside a variable against an array

  - by Jamex

  Hi, I have a variable, $var, that contains a string of characters, this is a dynamic variable that contains the values from inputs. $var could be 'abc', or $var could be 'blu', I want to match the string inside variable against an array, and return all the matches. $array = array("blue", "red", "green"); What is the correct syntax for writing the code in php, my rough code is below $match = preg_grep($var, $array); (incorrect syntax of course) I tried to put quotes and escape slashes, but so far no luck. Any suggestion? TIA

• Sending url params and POST body to a MVC 2 Controller

  - by Luiggi

  Hi, I'm having some issues trying to make a HTTP PUT (or POST) using WebClient against a MVC 2 controller. The exception is: The parameters dictionary contains a null entry for parameter 'total' of non-nullable type 'System.Int32' for method 'System.Web.Mvc.ActionResult Company(System.Guid, Int32, Int32, System.String)' The controller action is: [HttpPut] public ActionResult Company(Guid uid, int id, int total, string url) The route is: routes.MapRoute( "CompanySet", "job/active/{uid}/company/{id}", new { controller = "Job", action = "Company" } ); As you may see, what I want is to send the 'uid' and 'id' parameters via url, but the 'total' and 'url' parameters as part of the PUT or POST body. I've also tried to merge the latter parameters into a class (i.e., CompanySetMessage), doing it no longer raises an exception but I dont receive the values on the server side. Any ideas? Thank you!

• Pass dynamic value in URL with CakePHP

  - by Renato Dinhani Conceição

  I have the following method that performs an Ajax request passing some dynamic value obtained from a select input. It works fine, but the dynamic value is passed as parameter in the URL, something like states/listCities/?big_string_of_serialized_parameter . $this->Js->event( 'change', $this->Js->request( array( #url 'controller' => 'states', 'action' => 'listCities'), array( # ajax options that generates the serialized parameter 'update' => '#DealerCityId', 'data' => '$("#DealerStateId").serialize()', 'dataExpression' => true ) ) ); I'm trying to do this in a more friendly URL way, something like states/listCities/2. It's possible in CakePHP to generate a friendly URL like this with dynamic value from a input or is only possible passing the dynamic values as parameters?

• two HashMap iteration

  - by user431276

  I have two HashMaps and I can iterate both hashmaps with following code Iterator it = mp.entrySet().iterator(); while (it.hasNext()) { Map.Entry pairs = (Map.Entry)it.next(); String firstVal = pairs.getValue(); } Iterator it2 = mp2.entrySet().iterator(); while (it2.hasNext()) { Map.Entry pairs2 = (Map.Entry)it.next(); String SecondVal = pairs2.getValue(); } myFunction(firstVal, SecondVal) Is there anyway to iterate two hashmaps at the same time without using two loops? Currently, I have a method that accepts two parameters and each parameter value is stored in first and second hashmap. I have to iterate first hash then second to get values. I think there must be a good way to do it but I don't know :( P.S: there could be some errors in above code as this is just an example to explain my problem. Each iterator is a method in original program and accept one parameter. I couldn't copy past real time functions as they are HUGE !
