• Should I learn Haskell or F# if I already know OCaml?

  - by Unknown

  I am wondering if I should continue to learn OCaml or switch to F# or Haskell. Here are the criteria I am most interested in: Longevity Which language will last longer? I don't want to learn something that might be abandoned in a couple years by users and developers. Will Inria, Microsoft, University of Glasgow continue to support their respective compilers for the long run? Practicality Articles like this make me afraid to use Haskell. A hash table is the best structure for fast retrieval. Haskell proponents in there suggest using Data.Map which is a binary tree. I don't like being tied to a bulky .NET framework unless the benefits are large. I want to be able to develop more than just parsers and math programs. Well Designed I like my languages to be consistent. Please support your opinion with logical arguments and citations from articles. Thank you.

• What is the 'noreq' Filter Type an Alias for?

  - by Alan Storm

  I'm looking in to Magento's filtering options (Ecommerce System and PHP Framekwork with an expansive ORM system). Specifically the addFieldToFilter method. In this method, you specify a SQLish filter by passing in a single element array, with the key indicating the type of filter. For example, array('eq'=>'bar') //eq means equal array('neq'=>'bar') //neq means not equal would each give you a where clause that looks like where field = 'bar'; where field != 'bar'; So, deep in the bowels of the source, I found a comparison type named 'moreq' that maps to a = comparison operator array('moreq'=>'27') where field >= 27 The weird thing is, there's already a 'gteq' comparision type array('gteq'=>'27') where field >= 27 So, my question is, what does moreq stand for? Is is some special SQL concept that's supported in other databases that the Magento guys wants to map to MySQL, or is it just "more required" and an example what happens when you're doing rapid agile and trying to maintain backwards compatibility.

• Online Game programming in Google App Engine: AI

  - by Hortinstein

  I am currently in the planning stages of a game for google app engine, but cannot wrap my head around how I am going to handle AI. I intend to have persistant NPCs that will move about the map, but short of writing a program that generates the same XML requests I use to control player actions, than run it on another server I am stuck on how to do it. I have looked at the Task Queue feature, but due to long running processes not being an option on the App engine, I am a little stuck. I intend to run multiple server instances with 200+ persistant NPC entities that I will need to update. Most action is slowly roaming around based on player movements/concentrations, and attacking close range players(you can probably guess the type of game im developing)

• Manipulating both unicode and ASCII character set in C#

  - by Murlex

  I have this mapping in my C# application string [,] unicode2Ascii = { { "&#3001;", "\x86" } }; ஹ - is the unicode value for a tamil literal "ஹ". This is the raw hex literal for the unicode value saved by MS Word as a byte sequence. I am trying to map these unicode value "strings" to a hex value under 255 (so as to accommodate non-unicode supported systems). I trying to use string.replace like this: S = S.replace(unicode2Ascii[0,0], unicode2Ascii[0,1]); However the resultant ouput has a ? instead of the actual hex 0x86 stored. Any pointer on how I could set the encoding for the second element of that array to something like windows-1252? Or is there a better way to do this conversion? thanks in advance

• C++ associative array with arbitrary types for values

  - by Gerald Kaszuba

  What is the best way to have an associative array with arbitrary value types for each key in C++? Currently my plan is to create a "value" class with member variables of the types I will be expecting. For example: class Value { int iValue; Value(int v) { iValue = v; } std::string sValue; Value(std::string v) { sValue = v; } SomeClass *cValue; Value(SomeClass *v) { cValue = c; } }; std::map<std::string, Value> table; A downside with this is you have to know the type when accessing the "Value". i.e.: table["something"] = Value(5); SomeClass *s = table["something"].cValue; // broken pointer Also the more types that are put in Value, the more bloated the array will be. Any better suggestions?

  I have the following code: <map title="Authoring Guide"> <topicref href="topics/front-matter.xml"/> <topichead navtitle="My TopicHead"> <topicref href="topics/who-should-use.xml"/> </topichead> ... When the PDF is generated using oXygen editor with the PDF Legacy plugin, the topichead element is completely ignored, yet the nested topicref is in the PDF. Can anyone explain why a topichead might be ignored in processing? thanks!!

• Mapping tables from an existing database to an object -- is Hibernate suited?

  - by Bernhard V

  Hello! I've got some tables in an existing database and I want to map them to a Java object. Actually it's one table that contains the main information an some other tables that reference to such a table entry with a foreign key. I don't want to store objects in the database, I only want to read from it. The program should not be allowed to apply any changes to the underlying database. Currently I read from the database with 5 JDBC sql queries and set the results then on an object. I'm now looking for a less code intensive way. Another goal is the learning aspect. Is Hibernate suitable for this task, or is there another ORM framework that better fits my requirement?

• understanding memory mapping in directx

  - by numerical25

  So my question is ... " When your using the mapping feature to write into a memory buffer, are you really just saving the whole procedure into a queue so directX executes it when finished with other tasks???" I ask this question because this is my perception of mapping when writing to a buffer. I just want to make sure my perception is correct. I understand that the monitor moves extremely slow in compared to the processor, and I am sure the processor can execute 10 times the amount the screen can refresh. So is this one of the reason you should map when writing to a buffer. so each procedure can be done in a orderly fashion. If someone could elaborate, that would be great. thanks

• What's a good algorithm for searching arrays N and M, in order to find elements in N that also exist

  - by GenTiradentes

  I have two arrays, N and M. they are both arbitrarily sized, though N is usually smaller than M. I want to find out what elements in N also exist in M, in the fastest way possible. To give you an example of one possible instance of the program, N is an array 12 units in size, and M is an array 1,000 units in size. I want to find which elements in N also exist in M. (There may not be any matches.) The more parallel the solution, the better. I used to use a hash map for this, but it's not quite as efficient as I'd like it to be. Typing this out, I just thought of running a binary search of M on sizeof(N) independent threads. (Using CUDA) I'll see how this works, though other suggestions are welcome.

• jQuery: How to collect values from sliders into simple object with id as keys

  - by Svish

  I have several jQuery UI Sliders and I want to collect their values. Thought it would be a simple task, but when I was going to do it I got stuck and not quite sure what to do anymore :p The object I would like to end up with should look something like this: { a: 80, b: 90, c: 20, ... } I can do it manually like this: var values = { a: $('#a').slider('value'), b: $('#b').slider('value'), c: $('#c').slider('value'), ... }; But that's a bit tedious, especially if I need to add or remove or rename. Was hoping I could do something with the map or each function or something like that, but I can't figure it out. Anyone have some clever ideas?

• AutoMapper: How to transform object graph to into?

  - by epitka

  If I have a one-to-many relationship and I want to transorm this into a list of flat Dto-s where some attributes of parent and some of child appear in a dto, is this something that is supported out-of-box with AutoMapper? For example if I have something like this Parent 1. ParentId 2. ParentAttr1 3. List<Child> Child 1. ChildId 2. ChildAttr1 2. ChildAttr2 Dto 1. ParentId 2. ChildId 2. ChildAttr1 3. ChildAttr2 How do I project Parent into a Dto where for each child in parent I will get an instace of Dto? I've setup two maps Parent-Dto and Child-Dto but just doing _mapper.Map(parentInstance) only projects parents attributes. Does this have to be done in two steps, where I would iterate children myself?

• Action method expected parameter named Id and nothing otherwise

  - by codingbiz

  The Error The parameters dictionary contains a null entry for parameter 'UserId' of non-nullable type 'System.Int64' for method 'System.Web.Mvc.ActionResult Predict(Int64)' in 'sportingbiz.Controllers.PredictionController'. An optional parameter must be a reference type, a nullable type, or be declared as an optional parameter. Parameter name: parameters This does not work. Throws the error mentioned above http://mysite/User/Profile/15 This works http://mysite/User/Profile/?UserID=15 The Controller Action public ActionResult Profile(long UserID) { } When I changed the parameter name to Id it works. I think it's because Id was specified in the route collection (Global.asax). Is it possible to tell MVC that UserId should map to Id without changing it in the Global.asax

• Dynamic binding in C++

  - by chmike

  I'm implementing a CORBA like server. Each class has remotely callable methods and a dispatch method with two possible input, a string identifying the method or an integer which would be the index of the method in a table. A mapping of the string to the corresponding integer would be implemented by a map. The caller would send the string on the first call and get back the integer with the response so that it simply has to send the integer on subsequent calls. It is just a small optimization. The integer may be assigned dynamically on demand by the server object. The server class may be derived from another class with overridden virtual methods. What could be a simple and general way to define the method binding and the dispatch method ?

• How to email CLLocationCoordinate2D as a link

  - by lucasweb

  I am trying to emulate the Maps 'Share Location' via email functionality. I have the latitude and longitude of my location and am currently using it to display the location on a map via MKMapView. I also have functionality that composes an email from the app and I would like to include the location in it but can not figure out how to construct a link, using the longitude and latitude. I have seen other apps with apps with this functionality so I know it is possible. Any help would be much appreciated. Thanks in advance.

• How do you remove the Bing Disambiguation Dialog via API call?

  - by Justin Dearing

  I am integrating bing maps into a web page. I am calling the GetDirections() method of my VEMap option. and setting the VERouteOptions.ShowDisambiguation property to true when I call VEMap.GetDirections(). So sometimes I get the following dialog: The problem is sometimes the user will enter a second set of directions into my form, and dialog remains. I've done the following to attempt to correct it: // In case the disambiguation dialog a.k.a "" is present from a previous direction search var disambiguationDialogElement = $('#myMap_veplacelistpanel')[0]; if (typeof (disambiguationDialogElement) == "object") { map.DeleteControl(disambiguationDialogElement); } It seems to work, but it feels like a suboptomial approach. Is there a better way to do it?

• Freeing Java memory at a specific point in time

  - by Marcus

  Given this code, where we load a lot of data, write it to a file, and then run an exe.. void myMethod() { Map stuff = createMap(); //Consumes 250 MB memory File file = createFileInput(stuff); //Create input for exe runExectuable(file); //Run Windows exe } What is the best way to release the memory consumed by stuff prior to running the exe? We don't need this in memory any more as we have dumped the data to a file for input to the exe... Is the best method to just set stuff = null prior to runExecutable(file)?

• execute external command / application from java

  - by IttayD

  I'm looking for a package to support reliably executing external processes from Java. My criteria: Abstract over OS. So if I want to run 'foo', it will look for 'foo.bat', 'foo.exe' under windows and 'foo' under other OSs (or, have a way of passing a map of os-command) Being able to execute Java classes by simply giving the class name and arguments (so the package locates the java command, copies jvm flags and then executes) Process stdout and stderr properly Watchdog / Monitoring capabilities I've looked at commons-exec but it looks like it answers only 3 & 4. Ant has support for execution but looks like an overkill to use it for this purpose only.

• Hibernate mapping to manage bidirectional relationship using intermediate table

  - by shikarishambu

  I have an object hierarchy that is as follows. Party inherited by Organization and Person Organization inherited by Customer, Vendor Person inherited by Contact In the database I have the following tables Party, Customer, Vendor, Contact. All of them have a corresponding row in Party table. Contact belongs to either Vendor or Customer. I have a field on the Contact table for org_party_id. However, since the organization can be either a Customer or Vendor I need to be able to look at different tables. Is there a way to map this in hibernate? Or, a better way to manage it in DB/ hibernate?

• C++ get method - returning by value or by reference

  - by HardCoder1986

  Hello! I've go a very simple question, but unfortunately I can't figure the answer myself. Suppose I've got some data structure that holds settings and acts like a settings map. I have a GetValue(const std::string& name) method, that returns the corresponding value. Now I'm trying to figure out - what kind of return-value approach would be better. The obvious one means making my method act like std::string GetValue(const std::string& name) and return a copy of the object and rely on RVO in performance meanings. The other one would mean making two methods std::string& GetValue(...) const std::string& GetValue(...) const which generally means duplicating code or using some evil constant casts to use one of these routines twice. #Q What would be your choice in this kind of situation and why?

• Can you help me refactor this piece of clojure code to produce a seq?

  I want to produce a seq that I can later do a (map) over. It should look like this: ((0 0) (0 1) (0 2) (0 3) ... (7 7)) The piece of code I have to do it right now seems very, very ugly to produce such a simple result. I need some help getting this straight. (loop [y 0 x 0 args (list)] (if (and (= y 7) (= x 7)) (reverse (conj args (list y x))) (if (= x 7) (recur (+ y 1) 0 (conj args (list y x))) (recur y (+ x 1) (conj args (list y x))))))
