• Adding International support in Erlang Web 1.4

  - by Roberto Aloi

  I'm trying to add international support for a website based on the Erlang Web 1.4. I would like to have a couple of links on every page (the notorious Country flags) that allow the user to set his language session variable. What I have right now is a link like: <li><a href="/session/language/en">English</a></li> Where, in the session controller I do: language(Args) -> LanguageId = proplists:get_value(id, Args), case language_is_supported(LanguageId) of false -> ok; true -> wpart:fset("session:lang", LanguageId) end, {redirect, "/"}. The problem is that, after setting the preferred language, I would like the user to be redirected to the page he was visiting before changing the language. In this case the "__path" variable doesn't help because it contains the language request and not the "previous" one. How could I resolve this situation? I'm probably using the wrong approach but I cannot thing to anything else right now.

• MDX: Filtering a member set by a measure's table values

  - by oyvinro

  I have some numbers in a fact table, and have generated a measure which use the SUM aggregator to summarize the numbers. But the problem is that I only want to sum the numbers that are higher than, say 10. I tried using a generic expression in the measure definition, and that works of course, but the problem is that I need to be able to dynamically set that value, because it's not always 10, meaning users should be able to select it themselves. More specifically, my current MDX looks like this: WITH SET [Email Measures] AS '{[Measures].[Number Of Answered Cases], [Measures].[Max Expedition Time First In Case], [Measures].[Avg Expedition Times First In Case], [Measures].[Number Of Incoming Email Requests], [Measures].[Avg Number Of Emails In Cases], [Measures].[Avg Expedition Times Total],[Measures].[Number Of Answered Incoming Emails]}' SET [Organizations] AS '{[Organization.Id].[860]}' SET [Operators] AS '{[Operator.Id].[3379],[Operator.Id].[3181]}' SET [Email Accounts] AS '{[Email Account.Id].[6]}' MEMBER [Time.Date].[Date Period] AS Aggregate ({[Time.Date].[2008].[11].[11] :[Time.Date].[2009].[1].[2] }) MEMBER [Email.Type].[Email Types] AS Aggregate ({[Email.Type].[0]}) SELECT {[Email Measures]} ON columns, [Operators] ON rows FROM [Email_Fact] WHERE ( [Time.Date].[Date Period] ) Now, the member in question is the calculated member [Avg Expedition Times Total]. This member takes in two measures; [Sum Expedition Times] and [Nr of Expedition Times] and splits one on the other to get the average, all this presently works. However, I want [Sum Expedition Times] to only summarize values over or under a parameter of my/the user's wish. How do I filter the numbers [Sum Expedition Times] iterates through, rather than filtering on the sum that the measure gives me in the end?

• Using SimpleDB (with SimpleSavant) with POCO / existing entities, not attributes on my classes

  - by alex

  I'm trying to use Simple Savant within my application, to use SimpleDB I currently have (for example) public class Person { public Guid Id { get; set; } public string Name { get; set; } public string Description { get; set; } public DateTime DateOfBirth { get; set; } } To use this with Simple Savant, i'd have to put attributes above the class declaration, and property - [DomainName("Person")] above the class, and [ItemName] above the Id property. I have all my entities in a seperate assembly. I also have my Data access classes an a seperate assembly, and a class factory selects, based on config, the IRepository (in this case, IRepository I want to be able to use my existing simple class - without having attributes on the properties etc.. In case I switch out of simple db, to something else - then I only need to create a different implementation of IRepository. Should I create a "DTO" type class to map the two together? Is there a better way?

• Java: How do I implement a method that takes 2 arrays and returns 2 arrays?

  - by HansDampf

  Okay, here is what I want to do: I want to implement a crossover method for arrays. It is supposed to take 2 arrays of same size and return two new arrays that are a kind of mix of the two input arrays. as in [a,a,a,a] [b,b,b,b] ------ [a,a,b,b] [b,b,a,a]. Now I wonder what would be the suggested way to do that in Java, since I cannot return more than one value. My ideas are: - returning a Collection(or array) containing both new arrays. I dont really like that one because it think would result in a harder to understand code. - avoiding the need to return two results by calling the method for each case but only getting one of the results each time. I dont like that one either, because there would be no natural order about which solution should be returned. This would need to be specified, though resulting in harder to understand code. Plus, this will work only for this basic case, but I will want to shuffle the array before the crossover and reverse that afterwards. I cannot do the shuffling isolated from the crossover since I wont want to actually do the operation, instead I want to use the information about the permutation while doing the crossover, which will be a more efficient way I think.

• javascript var assignment conversion to target type

  - by pbhd

  searching for a function, which converts rhs to the type of lhs. e.g. var x=false // x is boolean now; x=assign (x, "true"); //should convert "true" to boolean and return that x=assign (x, 1); // dto, convert 1 to true x=0 // x is number x=assign (x, "123"); // should convert "123" to 123; so such a function can be written, thats not the question. But: Is there somewhere a somehow complete implementation of such a thing? I started with something like that: function assign (v, x) { if (typeof v==typeof x) { return x; } switch (typeof v) { case 'boolean' : { return x=='true'?true:false; } case 'number' : { return parseFloat(x); } } return "xxx"; } var v=true; var x='true'; var r1=assign (v, x); console.log (typeof r1+ " "+r1); v=10; x="123"; var r1=assign (v, x); console.log (typeof r1+ " "+r1); which of course is not complete, but maybe shows what I'm goig for.

• Maven exec bash script and save output as property

  - by djechlin

  I'm wondering if there exists a Maven plugin that runs a bash script and saves the results of it into a property. My actual use case is to get the git source version. I found one plugin available online but it didn't look well tested, and it occurred to me that a plugin as simple as the one in the title of this post is all I need. Plugin would look something like: <plugin>maven-run-script-plugin> <phase>process-resources</phase> <!-- not sure where most intelligent --> <configuration> <script>"git rev-parse HEAD"</script> <!-- must run from build directory --> <targetProperty>"properties.gitVersion"</targetProperty> </configuration> </plugin> Of course necessary to make sure this happens before the property will be needed, and in my case I want to use this property to process a source file.

• C++ reinterpret cast ?

  - by Ian

  I would like to cast one object of the class PointsList to another object Points3DList (and vice versa) where: template <class T> class PointsList { protected: std::vector <Point <T> *> points; //Only illustration, not possible with templaes }; and template <class T> class Points3DList { protected: std::vector <Point3D<T> *> points; //Only illustration, not possible with templaes }; Between Point and Point3D there is no relationship (inheritance nor composition)... template <class T> class Point { protected: T x; T y; }; template <class T> class Point3D { protected: T x; T y; T z; }; What do you think about conversion Points3DList <T> *pl3D = new Points3DList <T> (); ... PointsList <T> *pl = reinterpret_cast < PointList <T> * > ( pl3D ); where pl3D represents pointer to Points3DList object.. Can reinterpret_cast be used in this case or it is better to create a conversion function? Data model in this case can not be changed...

• Sorting page flow for has_many in Rails

  - by Gareth

  I have a page flow allowing the user to choose an object ("Player") to add to a has_many :players association in another model. 1 => List existing players for object [Enter player name] 2 => List of matching players [Select player] 3 => Confirmation page [Press 'Add'] 4 => Done I want users to be able to choose "New Player" instead of selecting a player at step 2, in which case the user will go through the standard New Player process elsewhere on the site. However, after that's done, the user should return to step 3 with the new player in place. I don't know what the best way is to implement this. I don't want to duplicate the player creation code, but I don't want to dirty up the player creation code too much just for this case. I also don't want to start sticking IDs in the session if I can help it. It's fine in simple cases but if the user ever has two windows/tabs then things start behaving badly. What do you think?

• Can Visual Studio (should it be able to) compute a diff between any two changesets associated with a

  - by Hamish Grubijan

  Here is my use case: I start on a project XYZ, for which I create a work item, and I make frequent check-ins, easily 10-20 in total. ALL of the code changes will be code-read and code-reviewed. The change sets are not consecutive - other people check-in in-between my changes, although they are very unlikely to touch the exact same files. So ... at the en of the project I am interested in a "total diff" - as if there was a single check-in by me to complete the entire project. In theory this is computable. From the list of change sets associated with the work item, you get the list of all files that were affected. Then, the algorithm can aggregate individual diffs over each file and combine them into one. It is possible that a pure total diff is uncomputable due to the fact that someone else renamed files, or changed stuff around very closely, or in the same functions as me. I that case ... I suppose a total diff can include those changes by non-me as well, and warn me about the fact. I would find this very useful, but I do not know how to do t in practice. Can Visual Studio 2008/2010 (and/or TFS server) do it? Are there other source control systems capable of doing this? Thanks.

• JQuery/AJAX: Loading external DIVs using dynamic content

  - by ticallian

  I need to create a page that will load divs from an external page using Jquery and AJAX. I have come across a few good tutorials, but they are all based on static content, my links and content are generated by PHP. The main tutorial I am basing my code on is from: http://yensdesign.com/2008/12/how-to-load-content-via-ajax-in-jquery/ The exact function i need is as follows: Main page contains a permanent div listing some links containing a parameter. Upon click, link passes parameter to external page. External page filters recordset against parameter and populates div with results. The new div contains a new set of links with new parameters. The external div is loaded underneath the main pages first div. Process can then be repeated creating a chain of divs under each other. The last div in the chain will then direct to a new page collating all the previously used querystrings. I can handle all of the PHP work with populating the divs on the main and external pages. It's the JQuery and AJAX part i'm struggling with. $(document).ready(function(){ var sections = $('a[id^=link_]'); // Link that passes parameter to external page var content = $('div[id^=content_]'); // Where external div is loaded to sections.click(function(){ //load selected section switch(this.id){ case "div01": content.load("external.php?param=1 #section_div01"); break; case "div02": content.load("external.php?param=2 #section_div02"); break; } }); The problem I am having is getting JQuery to pass the dynamically generated parameters to the external page and then retrieve the new div. I can currently only do this with static links (As above).

• Is this method a good aproach to get SQL values from C#?

  - by MadBoy

  I have this little method that i use to get stuff from SQL. I either call it with varSearch = "" or varSearch = "something". I would like to know if having method written this way is best or would it be better to split it into two methods (by overloading), or maybe i could somehow parametrize whole WHERE clausule? private void sqlPobierzKontrahentDaneKlienta(ListView varListView, string varSearch) { varListView.BeginUpdate(); varListView.Items.Clear(); string preparedCommand; if (varSearch == "") { preparedCommand = @" SELECT t1.[KlienciID], CASE WHEN t2.[PodmiotRodzaj] = 'Firma' THEN t2.[PodmiotFirmaNazwa] ELSE t2.[PodmiotOsobaNazwisko] + ' ' + t2.[PodmiotOsobaImie] END AS 'Nazwa' FROM [BazaZarzadzanie].[dbo].[Klienci] t1 INNER JOIN [BazaZarzadzanie].[dbo].[Podmioty] t2 ON t1.[PodmiotID] = t2.[PodmiotID] ORDER BY t1.[KlienciID]"; } else { preparedCommand = @" SELECT t1.[KlienciID], CASE WHEN t2.[PodmiotRodzaj] = 'Firma' THEN t2.[PodmiotFirmaNazwa] ELSE t2.[PodmiotOsobaNazwisko] + ' ' + t2.[PodmiotOsobaImie] END AS 'Nazwa' FROM [BazaZarzadzanie].[dbo].[Klienci] t1 INNER JOIN [BazaZarzadzanie].[dbo].[Podmioty] t2 ON t1.[PodmiotID] = t2.[PodmiotID] WHERE t2.[PodmiotOsobaNazwisko] LIKE @searchValue OR t2.[PodmiotFirmaNazwa] LIKE @searchValue OR t2.[PodmiotOsobaImie] LIKE @searchValue ORDER BY t1.[KlienciID]"; } using (var varConnection = Locale.sqlConnectOneTime(Locale.sqlDataConnectionDetails)) using (SqlCommand sqlQuery = new SqlCommand(preparedCommand, varConnection)) { sqlQuery.Parameters.AddWithValue("@searchValue", "%" + varSearch + "%"); using (SqlDataReader sqlQueryResult = sqlQuery.ExecuteReader()) if (sqlQueryResult != null) { while (sqlQueryResult.Read()) { string varKontrahenciID = sqlQueryResult["KlienciID"].ToString(); string varKontrahent = sqlQueryResult["Nazwa"].ToString(); ListViewItem item = new ListViewItem(varKontrahenciID, 0); item.SubItems.Add(varKontrahent); varListView.Items.AddRange(new[] {item}); } } } varListView.EndUpdate(); }

• Weird flex date issue

  - by CodeMonkey

  Flex is driving me CRAZY and I think it's some weird gotcha with how it handles leap years and none leap years. So here's my example. I have the below dateDiff method that finds the number of days or milliseconds between two dates. If I run the following three statements I get some weird issues. dateDiff("date", new Date(2010, 0,1), new Date(2010, 0, 31)); dateDiff("date", new Date(2010, 1,1), new Date(2010, 1, 28)); dateDiff("date", new Date(2010, 2,1), new Date(2010, 2, 31)); dateDiff("date", new Date(2010, 3,1), new Date(2010, 3, 30)); If you were to look at the date comparisons above you would expect to get 30, 27, 30, 29 as the number of days between the dates. There weird part is that I get 29 when comparing March 1 to March 31. Why is that? Is it something to do with February only having 28 days? If anyone has ANY input on this that would be greatly appreciated. public static function dateDiff( datePart:String, startDate:Date, endDate:Date ):Number { var _returnValue:Number = 0; switch (datePart) { case "milliseconds": _returnValue = endDate.time - startDate.time; break; case "date": // TODO: Need to figure out DST problem i.e. 23 hours at DST start, 25 at end. // Math.floor causes rounding down error with DST start at dayOfYear _returnValue = Math.floor(dateDiff("milliseconds", startDate, endDate)/(1000 * 60 * 60 * 24)); break; } return _returnValue; }

• Can one thread open a socket and other thread close it?

  - by Pkp

  I have some kernel threads in Linux kernel, inside my KLM. I have a server thread, that listens to the channel, Once it sees there is an incoming connection, it creates an accept socket, accepts the connection and spawns a child thread. It also passes the accepted socket to the child kernel thread as the (void *) argument. The code is working fine. I had a design question. Suppose now the threads have to be terminated, main and the child threads, what would be the best way to close the accept socket. I can see two ways, 1] The main thread waits for all the child threads to exit, each of the child threads close the accept sockets while exiting, the last child thread passes a signal to the main thread for it to exit . Here even though the main thread was the one that created the accept socket, the child threads close that socket, and they do this before the main thread exits. So is this acceptable? Any problems you guys forsee here? 2] Second is the main thread closes all the accept sockets it created before it exits. But there may be a possibility(corner case) that the main thread gets an exception and will have to close, so if it closes the accept sockets before exiting, the child threads using that socket will be in danger. Hence i am using the first case i mentioned.Let me know what you guys think?

• How to route 1 VPN through another on OS X?

  - by Eeep

  Hi everyone. Thanks a lot for your help! I've been tinkering with this for a while and have read many posts along with Googling for help, but my knowledge of TCP/IP is really weak... I have access to two different VPN servers. 1 Is set up in Network Settings and connects through PPP 2 Is set up through Tunnelblick and uses OpenVPN. I can connect to either tunnel #1 or tunnel #2, but not both one after the other... One of my major to-do's this year is study TCP/IP, but for now, would you be super-helpful and help me fix this really clearly? I have no experience with routing, DNS, gateways or any of that. If you tell me, "Set your gateway to XXX.XXX.XX.XXX" can you specify how I get that IP, off of what interface so I don't get messed up? I can figure out the terminal just fine if you let me know what to type, and I WILL read the man pages on everything you help me with. Thanks a million!

• How to explain to client that you can't give them some of the source

  - by Bo

  We have a number of AS/Flex components that we've built over time and improved upon. They've been turned into components so they can be reused in different projects and save us time. So you can think of them as part of an in-house framework of sorts. We're now realizing that it doesn't make sense to release the source code for these components to the various clients as part of the project, because technically this code isn't really owned by the clients. So my question When a client comes to you, how do you explain to them that you can't give them the full source code for those components. The client doesn't understand the difference, he just expects you to give them all the code for the site that he paid you to do. He doesn't understand that this code has taken you a lot longer to write than what he's paying for his site. But since he doesn't understand, he would get turned off and thinks you're ripping him off or something. How do you handle this situation? What do you tell clients upfront? Do you advertise it on your site from the very beginning? How do you handle their objections so they still hire you? As a side question, how often do you give AS and Flex source code to your clients? In the case when the code doesn't have any in-house components that you reuse in several projects, and in the case when it does have in-house components.

• Is there a more concise regular expression to accomplish this task?

  - by mpminnich

  First off, sorry for the lame title, but I couldn't think of a better one. I need to test a password to ensure the following: Passwords must contain at least 3 of the following: upper case letters lower case letters numbers special characters Here's what I've come up with (it works, but I'm wondering if there is a better way to do this): Dim lowerCase As New Regex("[a-z]") Dim upperCase As New Regex("[A-Z]") Dim numbers As New Regex("\d") Dim special As New Regex("[\\\.\+\*\?\^\$\[\]\(\)\|\{\}\/\'\#]") Dim count As Int16 = 0 If Not lowerCase.IsMatch(txtUpdatepass.Text) Then count += 1 End If If Not upperCase.IsMatch(txtUpdatepass.Text) Then count += 1 End If If Not numbers.IsMatch(txtUpdatepass.Text) Then count += 1 End If If Not special.IsMatch(txtUpdatepass.Text) Then count += 1 End If If at least 3 of the criteria have not been met, I handle it. I'm not well versed in regular expressions and have been reading numerous tutorials on the web. Is there a way to combine all 4 regexes into one? But I guess doing that would not allow me to check if at least 3 of the criteria are met. On a side note, is there a site that has an exhaustive list of all characters that would need to be escaped in the regex (those that have special meaning - eg. $, ^, etc.)? As always, TIA. I can't express enough how awesome I think this site is.

• Send form with jQuery using keypress()

  - by kexxcream

  What I have so far: I have a form in PHP that contain the following: <input type="submit" id="0" name="0" value="This button"> <input type="submit" id="1" name="1" value="This button"> <input type="hidden" id="response" name="response" value="150"> The problem: I would like to send the response value together with either name=1 or name=0, depending on which button the user submit. However, this should be done using the keyboard letters A and S. If a user press the letter A then the value 0 should be submitted, and if S is pressed then the value 1 should be sent. The jQuery code: $(document).ready(function() { // listens for any navigation keypress activity $(document).keypress(function(e) { switch(e.which) { // user presses the "a" case 97: submitViaKeypress("0"); break; // user presses the "s" key case 115: submitViaKeypress("1"); break; } }); }); // shows a given element and hides all others function submitViaKeypress(element_id) { var response = $('#response').attr('value'); $.ajax({ type: "POST", url: "initiate.php", data: "response=" + response + "&" + element_id + "=" + element_id }); } Goal: That "initiate.php receive two POST variables (response and either 0 or 1).

• Flash automatically names objects on stage "instance#"

  - by meowMIX3R

  Hi, I have 2 TLF text boxes already placed on my main stage. In the property inspector window I give these the instance names: "txt1" and "txt2". I am trying to have a single mouseup event, and figure out which text box it occurred on. My document class has the following code: package { import flash.display.Sprite; import flash.events.KeyboardEvent; public class SingleEvent extends Sprite{ public function SingleEvent() { // constructor code root.addEventListener(KeyboardEvent.KEY_UP, textChanged,false,0,true); } private function textChanged(e:KeyboardEvent){ trace(e.target.name); trace(" " + e.target); switch(e.target){ case txt1: trace("txt1 is active"); break; case txt2: trace("txt2 is active"); break; default: break; } } } } Example output is: instance15 [object Sprite] instance21 [object Sprite] Since the objects are already on the stage, I am not sure how to get flash to recognize them as "txt1" and "txt2" instead of "instance#". I tried setting the .name property, but it had no effect. In the publish settings, I have "Automatically declare stage instances" checked. Also, is it possible to have a single change event for multiple slider components? The following never fires: root.addEventListener(SliderEvent.CHANGE, sliderChanged,false,0,true); Thanks for any tips

• What does Postgres do when BEGIN is run on a connection in autocommit mode?

  - by DNS

  I'm trying to better understand the concept of 'autocommit' when working with a Postgres (psycopg) connection. Let's say I have a fresh connection, set its isolation level to ISOLATION_LEVEL_AUTOCOMMIT, then run this SQL directly, without using the cursor begin/rollback methods (as an exercise; not saying I actually want to do this): INSERT A INSERT B BEGIN INSERT C INSERT D ROLLBACK What happens to INSERTs C & D? Is autocommit is purely an internal setting in psycopg that affects how it issues BEGINs? In that case, the above SQL is unafected; INSERTs A & B are committed as soon as they're done, while C & D are run in a transaction and rolled back. What isolation level is that transaction run under? Or is autocommit a real setting on the connection itself? In that case, how does it affect the handling of BEGIN? Is it ignored, or does it override the autocommit setting to actually start a transaction? What isolation level is that transaction run under? Or am I completely off-target?

• Error Expected Loop VBScript

  - by Yoko21

  I have a script that opens up an excel file if the password provided is correct. If its wrong, it prompts a message. It works perfectly when I add a loop at the end. However, the problem is whenever the password is wrong the script won't stop asking for the password because of the loop. What I want is the script to quit/close if the password is wrong. I tried to remove the loop and replaced it with "wscript.quit" but it always prompts the message "expected loop". Here is the code I made. password = "pass" do ask=inputbox ("Please enter password:","DProject") select case ask case password answer=true Set xl = CreateObject("Excel.application") xl.Application.Workbooks.Open "C:\Users\test1\Desktop\test.xlsx" xl.Application.Visible = True Set xl = Nothing wscript.quit end select answer=false x=msgbox("Password incorrect... Aborting") loop until answer=true Is it possible to put a message like that counts when aborting. like "Aborting in 3.... 2... 1".

• Kill process started with System.Diagnostic.Process.Start("FileName")

  - by PedroC88

  Hello; I am trying to create an app that will perform actions on specific times (much like the Windows Task Scheduler). I am currently using Process.Start() to lunch the file (or exe) required by the task. I am initiating a process by calling a file (an .mp3) and the process starts WMP (since it is the default application), so far so good. Now I wan't to kill that process. I know that it is normal behavior for the Process.Start(string, string) to return nothing (null in C#) in this case. So I am asking how can i close WMP when I called it through Process.Start(string, string)?? Edit: Please note that I am not opening WMP directly with Process.Start() and this is the line with which I run the process: VB: Me._procs.Add(Process.Start(Me._procInfo)) C#: this._procs.Add(Process.Start(this._procInfo)) _procInfo is a ProcessStartInfo instance. _procInfo.FileName is "C:\route\myFile.mp3". That is why WMP opens. In any case, all of the Start() methods, except for the instance-one which returns a boolean, return nothing (null in C#), because WMP is not the process that was directly created (please note that WMP is run and the song does play).

• Testing Hibernate DAO, without building the universe around it.

  - by Varun Mehta

  We have an application built using spring/Hibernate/MySQL, now we want to test the DAO layer, but here are a few shortcomings we face. Consider the use case of multiple objects connected to one another, eg: Book has Pages. The Page object cannot exist without the Book as book_id is mandatory FK in Page. For testing a Page I have to create a Book. This simple usecase is easy to manage, but if you start building a Library, till you don't create the whole universe surrounding the Book and Page, you cannot test it! So to test Page; Create Library Create Section Create Genre Create Author Create Book Create Page Now test Page. Is there an easy way to by pass this "universe creation" and just test he page object in isolation. I also want to be able to test HQLs related to Page. eg: SELECT new com.test.BookPage (book.id, page.name) FROM Book book, Page page. JUnit is supposed to run in isolation, so I have to write the whole test case to create the Page. Any tips will be useful.

• SDL (And Others) Virtual Key Input

  - by David C

  Today I set up the input in my application for all the different keys. This works fine except for virtual keys, for example, caret or ampersand. Keys that normally need shift to be got at. Using SDL these virtual keys don't work. As in they do not register an event. if (event.type == SDL_KEYDOWN) { switch (event.key.keysym.sym) { case SDLK_CARET: Keys[KeyCodes::Caret] = KeyState::Down; break; case SDLK_UP: Keys[KeyCodes::Up] = KeyState::Down; break; default: break; } I am absolutely sure my system works with physical keys like Up. The program queries a keystate like so: if (Keys[KeyCode] == KeyState::Down) { lua_pushboolean(L, true); } else { lua_pushboolean(L, false); } KeyCode is passed in as an argument. So why are virtual keys, or keys that need shift to get at not working using SDL's KeyDown event type? Is more code needed to get to them? Or am I being stupid?
