• Which programming langauge is the funniest?

  - by Shervin

  I know there are tons of different programming languages, and some of them are made with a tad of sense of humor. But which one is the funniest in your opinion? I have heard of something called Moo (although I am not sure of the exact name), which was a programming language for the JVM. The basic idea was that the only syntax allowed was a fork of Moo, like this: moo; //Means something mooo; //means another thing moooooo; //means something else and so on. That is pretty funny IMO. Not so useful, and definitely not easy to learn, but quite funny.

• How have popular iPhone games been ported to Android?

  - by Cirrostratus

  I am not asking how could they have been, I want to know the real answer. Doodle Jump, Paper Toss and some others have versions on the iPhone and Android that are nearly exactly the same, with the iPhone version coming first. There is a small Objective-C compiler project for Android's NDK but the timing isn't right for these apps. There's also an Android port of Cocos2d but I doubt Doodle Jump used that. Titanium? Doubtful. As their respective code bases grow, I figure it'd get harder and harder to do an exact port from Objective-C to Java every release so I wonder if there is a better way. Are they sharing C++ code for example?

• RESTful Design: Paging Collections

  - by Koen Bok

  I am designing a REST api that needs paging (per x) enforces from the server side. What would be the right way to page through any collection of resources: Option 1: GET /resource/page/<pagenr> GET /resource/tags/<tag1>,<tag2>/page/<pagenr> GET /resource/search/<query>/page/<pagenr> Option 2: GET /resource/?page=<pagenr> GET /resource/tags/<tag1>,<tag2>?page=<pagenr> GET /resource/search/<query>?page=<pagenr> If 1, what should I do with GET /resource? Redirect to /resource/page/0, reply with some error or reply with the exact same as /resource/page/0 without redirecting?

• Is strftime (hour) showing wrong time?

  - by ander163

  I'm using this line to get the beginning time of the first day of the month. t = Time.now.to_date.beginning_of_month.beginning_of_day When i display this using t.strftime("%A %b %e @ %l:%m %p") it shows: Monday Feb 1 @ 12:02 AM The hour is always 12 (instead of 00), and more wierd the minute changes to match the month in integers. For the February date, it shows 12:02 AM I use .prior_month and .next_month on the variable to move forward or backwards in time. So when I move to June, this would display as Tuesday June 1 @ 12:06 AM But when I just show the value of "t" using a straight t.to_s, I get this time of 00:00:00, which is what I expect: Mon Feb 01 00:00:00 -0700 2010 A similar error occurs using end_of_day, but the hour is always 11 PM and the minute is the same integer value that matches the month in integers, i.e the time is 11:06 PM in June, 11:02 PM in February. Qurky? Admittedly a noob to Rails. Thanks for any comments or explanations.

• How should I compensate for a bad WSDL?

  - by Brabster

  I've come across several examples of SOAP-based web services where automated tooling fails to build a client that works. Investigating these examples leads me to believe that the WSDL the service uses to describe itself doesn't quite match the service that's being provided. Maybe a wrong type somewhere, a different data structure - something. I'm unsure what the most appropriate response is - if we assume that the obvious one (get the provider to fix their stuff) isn't available. Some options I can think of: Make a fixed WSDL? Hack the generated code? Any other options? No good options? What good experiences have people had? What works in a real environment? Thanks

• cant get my listbox to display objects

  - by Silvia Stoyanova

  Hello everyone I've been trying to put some objects in an ASP.NET list box but its just not working. I do have an overriden ToString method so I cant understand why this statement wont work. Here's the code that I use: for (int i = 0; i < fitnessClassList.Count(); i++) { lbDisplayItems.Items.Add(fitnessClassList.getFitnessClass(i)); } And the errors that I get: Error 2 Argument 1: cannot convert from 'FitnessClassManager.FitnessClassOpportunity' to 'System.Web.UI.WebControls.ListItem' Error 1 The best overloaded method match for 'System.Web.UI.WebControls.ListItemCollection.Add(System.Web.UI.WebControls.ListItem)' has some invalid arguments

• Terminate on instance "std::runtime_error" Hiphop-Php

  - by boundless08

  I have successfully built Hiphop-Php on an ubuntu server 12.04 LTS but when I run the command: $HPHP_HOME/src/hphp/hphp test.php This error occurs: terminate called after throwing an instance of 'std::runtime_error' what(): locale::facet::_S_create_c_locale name not valid Aborted (core dumped) The same error occured during the make command but I used sudo make and it dealt with that, but using sudo on the above just removes the Aborted (core dumped). This is happening on a remote server, but I have done the exact same before testing on a VM. I even got root access, as I thought that could help, but it's done nothing. Just so you know I built with USE_HHVM=0, I need the code unreadable and the bytecode format does this, but the VM I built was as well, I'm just stumped! Thanks in advance.

• WPF ItemsControl - how to know when the items finished loading, so that I can focus the first one?

  - by Tomáš Kafka

  Hi everyone, I have an ItemsControl in my View, that is bound to an ObservableCollection from ViewModel. The collection is filled, and afterwards an event from VM to view is raised (think search results and SearchFinished event). I would like to move keyboard focus to the first item in an ItemsControl, but when I do it in View's code-behind when handling SearchFinished, the items are not yet rendered (the collection is filled already, but wpf's rendering is asynchronous and didn't happen yet), so there is nothing to focus (Focus() needs to have the items' visual tree already constructed). I wanted to do (myItemsControl.ItemContainerGenerator.ContainerFromIndex(0) as UIElement).Focus();, but as the 0th item is not yet loaded, ContainerFromIndex(0) returns null. I tried delaying it with Dispatcher.BeginInvoke... with low priority, but that is dependent on exact timing and usually doesn't work. How can I wait until the first item in ItemsControl is Loaded?

• Returning partial address matches and mismatch position using L2S or SQL

  - by peter3

  I need to implement a method that takes an address split up into individual parts and returns any matching items from an address table. If no matches are found, I want to be able to return a value indicating where it failed. Each input param has a corresponding field in the table. The signature would look something like this: List<Address> MatchAddress(string zipCode, string streetName, string houseNumber, string houseLetter, string floor, string appartmentNo, out int mismatchPosition) { // return matching addresses // if none found, return the position where it stopped matching // zipCode is position 0, appartmentNo is position 5 // // an empty param value indicates "don't check" } I know I can construct the method such that I start with all the parameters, execute the query and then remove param by param (from the right side) until either a match is found or I run out of parameters, but can I construct a query that is more effective than that, i.e minimizing the number of calls to the db, maybe even as a single call?

• Socket : can an asynchronous Receive returns without reading all the bytes I asked for?

  - by NorthWind

  Hi; I was reading an article on Vadym Stetsiak's blog about how to transfer variable length messages with async sockets (url: http://vadmyst.blogspot.com/2008/03/part-2-how-to-transfer-fixed-sized-data.html). He says : What to expect when multiple messages arrive at the server? While dealing with multiple messages one has to remember that receive operation can return arbitrary number of bytes being read from the net. Typically that size is from 0 to specified buffer length in the Receive or BeginReceive methods. So, even if I tell BeginReceive to read 100 bytes, it may read less than that and returns??? I am developing a network-enabled software (TCP/IP), and I always receive the same exact number of bytes I asked for. I don't even understand the logic : why would Receive completes asynchronously if it didn't get every byte I asked for ... just keep waiting. Maybe it has something to do with IP vs TCP? Thank you for your help.

• DataSetProvider - DataSet to ClientDataSet

  - by nomad311

  I am trying to take data from a TMSQuery which is connected to my DB and populate a ClientDataSet with some of that data using a DataSetProvider. My problem is that I will need to modify some of this data before it can go into my ClientDataSet. The ClientDataSet has persistent fields that will not match up with the raw DB data. I can't even get a string from the DB into a memo field in ClientDataSet. The ClientDataSet is a part of my data tier so I will need to conform the data from the DB to the ClientDataSet field by field (well most will be able to go right through, but many will require routing and/or conversion). Does anyone have experience with this?

• How can I put rows of MySQL data under the appropriate titles using PHP?

  - by sfarbota

  I have the following MySQL table structure: num field company phone website 1 Gas abcd 123456789 abcd.com 2 Water efgh 987654321 efgh.com 3 Water ijkl 321654987 ijkl.com 4 Heat mnop 987654321 mnop.com 5 Gas qrst 123789654 qrst.com ... Is it possible with PHP (maybe using some mixture of GROUP_BY and ORDER_BY) to echo the data to the screen in the following format: Gas: abcd qrst 123456789 123789654 abcd.com qrst.com Water: efgh ijkl 987654321 321654987 efgh.com ijkl.com Heat: mnop 321654987 mnop.com The exact format of it isn't important. I just need for the different rows of data to be listed under the appropriate field with none of the fields repeated. I've been trying to figure this out for a while now, but I'm new to PHP and I can't seem to figure out how to do this, if it's even possible, or if there's a better way to organize my data to make it easier.

• How do I use a ListProperty(users.user) in a djangoforms.ModelForm on Google AppEngine?

  - by Gabriel

  I have been looking around a bit for info on how to do this. Essentially I have a Model: class SharableUserAsset(db.Model): name = StringProperty() users = ListProperty(users.User) My questions are: What is the best way to associate users to this value where they are not authenticated, visa vi invite from contacts list etc.? Is there a reasonable way to present a list control easily in a djangoforms.ModelForm? Once a user logs in I want to be able to check if that user is in the list for any number of SharableUserAsset class "records", how do I do that? Does user evaluate as a match to an email address or is there a way to look up a valid user against an email address?

• Regex to validate SMTP Responses?

  - by Alix Axel

  I'm writing a regular expression that can interactively validate SMTP responses codes, once the SMTP dialog is completed it should pass the following regex (some parentheses added for better readability): ^(220)(250){3,}(354)(250)(221)$ Or with(out) authentication: ^(220)(250)((334){2}(235))?(250){2,}(354)(250)(221)$ I'm trying to do rewrite the above regexes so that I can interactively check if the dialog is going as expected, otherwise politely send a QUIT command and close the connection saving bandwidth and time, but I'm having a hard time writing an optimal regex. So far I've managed to come up with: ^(220(250(334(235(250(354(250(221)?)?)?){0,})?){0,2})?)?$ Which, besides only matching authenticated connections, has some bugs... For instance, it matches: 220250334235250354250221 220250334334235250354250221 I've also tried the following modification: ^(220(250)?)?((334(235)?){2})?(250(354(250(221)?)?)?){0,}$ This one accepts non-authenticated responses but it fails to match 220250334 and wrongly matches 220250334334235250354250221 (at least 2 250 are needed before the 354 response code). Can someone help me out with this? Thanks in advance.

• Documentation of a software project

  - by anijhaw

  I am working with a team that works on a very large software project, we have tons of Documentation that is written in MS WORD format with nohyperlinked indexes, no search ability. Everyday we waste our time trying to find the exact document or reference. I was thinking if there was way or even a professional tool that would convert all this into a wiki format and maybe with a little manual (painful) help be organised into something that improves the accessibility. I use Google Desktop Search to make my life a little easier but its not the best solution I just want to know if any of you faced similar problems and possible solutions to this issue.

• Weird Workflow Behavior in Sharepoint 2007

  - by frbry

  I have a Document Library A and a list B. When a document added to A, an item is created in B with the Title = A.Url. Another workflow runs whenever a document is updated in A which makes a lookup: B.Title = A.Url, and changes another column in B in found item. Item Change Workflow always gives "Error Occurred: List item is not found". I modified the workflow to send me an e-mail containing the new (but unchanged) A.Url. It sent me the exact string with the one already in list B. Anyways, why it can't find the item when the two columns are equal? Thanks in advance. Edit I literally hate Microsoft Sharepoint.

• How do I handle a JSON request returning a String in JQuery?

  - by knt

  Hi all, New to json/jQuery so sorry if this has an obvious answer. I'm doing an ajax request in jQuery that's something like: $.ajax({ url: theURL, dataType: 'jsonp', type: 'get', success: function(data) { alert("it's there"); } }); The request asks whether a given object is in a database. If it is, it returns something of the format: { "text": "duck", "canonical_name": "duck", "language": { "id": "en" }} However, if the object isn't there, it returns: Not Found As in...literally that exact string, not in any kind of json format as far as I know. Is there any way I can get my ajax to detect this? Right now it doesn't even seem to be acknowledging that it got anything back in the latter case. The json code wasn't written by me. It can possibly be fixed if this is not the correct format and there's absolutely nothing I can do from my end to work with this, but I'd really like to try to find some kind of workaround if possible. Thanks very much!

• J2ME TextField Exception

  - by Bob

  When I instantiate a textField, I have a number in it that I want to be the default text. The problem is, I can't seem to be able to place that value into the textfield without getting an error. The strange thing about it is that the same TextField is what I use to set the value of the variable containing the number. TextField myTF = new TextField("Number", value, 10, TextField.NUMERIC); When I run this code, I receive an exception stating that value doesn't match the constraints of TextField.NUMERIC. However, when I check the vale of the value of the variable, I get the following output: value = 1234567890 value.length() = 10 The value is set by the same TextField, saved to the phone that I am working on, and when loaded from the phone's settings, throws an exception.

• Web service can't open named pipe - access denied

  - by Patrick

  Hi All, I've got a C++ service which provides a named pipe to clients with a NULL SECURITY_ATTRIBUTES as follows: hPipe = CreateNamedPipe( lpszPipename, PIPE_ACCESS_DUPLEX | FILE_FLAG_OVERLAPPED, PIPE_TYPE_BYTE | PIPE_READMODE_BYTE | PIPE_WAIT, PIPE_UNLIMITED_INSTANCES, BUFSIZE, BUFSIZE, 0, NULL); There is a dll which uses this pipe to get services. There is a c# GUI which uses the dll and works fine. There is a .net web site which also uses this dll (the exact same one on the same PC) but always gets permission denied when it tries to open the pipe. Any one know why this might happen and how to fix it? Also does anyone know of a good tutorial on SECURITY_ATTRIBUTES because I haven't understood the msdn info yet. Thanks, Patrick

• implicit parameter definition in class

  - by coubeatczech

  implicit val odkaz = head; def vypis(implicit odkaz:Prvek):String = { odkaz match{ case null => "" case e => e.cislo + " " + e.pocet + "\n" + vypis(e.dalsi) } } ... def main(args:Array[String]){ val q = new MyQueue() // insert some values println(q.vypis) } This method(vypis) is a member of an queue-class so I'll always want to implicity start the recursion from the start of the queue, when calling the method from outside. Is there a way how to write it, that the method from outside calling, there's no paramter, but in inside, there's a parameter - for recursion...? The compiler complains that the parameter is not defined when called from outside

• F# return type coercion

  - by Alex

  Hi, In F# I have a function that returns System.Linq.Expression instances: and System.Object with member this.ToExpression() = match this with | :? System.Int32 -> Expression.Constant(this) :> Expression | :? System.Boolean -> Expression.Constant(this) :> Expression | :? Tml.Runtime.Seq as s -> s.ToExpression() | _ -> failwith "bad expression" If I omit the type coercions on the return values F# will infer the return type of the function to ConstantExpression. My first thought was to explicitly mark the return type as being : #Expression, but that didn't work. Is there a more elegant way of doing this that doesn't involve manually casting return types to the most generic type? Thanks.

• Getting differences between WVGA800 and WVGA854 in Android Emulator

  - by Droidy

  So far I just have one XML layout file, and one drawable directory, drawable-hdpi. I first want to target the high density screens. I added a bunch of imagebuttons to a relativelayout and everything looks perfect in the WVGA800 emulator. The problem arises when I view it in the WVGA854 emulator. Not only do the imagebuttons not position the same, but the images are blurry. I used dip for the layout margins on the imagebuttons even though it shouldn't matter in this case because WVGA800 and 854 are both high density. What is the problem? Why would it look totally different on emulators that have the same density and almost have the same exact screen dimensions? Thanks!

• Why isn't Passenger respecting my custom log format?

But when I run the app via Passenger, the format being logged is Rails' default. Why doesn't Passenger write to the log file like Mongrel does?
