• How hard programming is? Really. [closed]

  - by Bubba88

  Hi! The question is about your perception of programming activity. How hard/exacting this task is? There is much buzz about programming nowadays, people say that programmers are smart, very technical and abstract at a time, know much about world, psychology etc.. They say, that programmers got really powerful brain thing, cause there is much to keep in consideration simultaneously again with much information folded into each other associatively (up 10 levels of folding they say))) Still, there are some terms to specify at our own.. So that is the question: What do you think about programming in general? Is it hard? Is it 'for everyone' or for the particular kind of people only? How much non-CS background do you need to program (just to program, really; enterprise applications for example)? How long is the learning curve? (again, for programming in general) And another bunch of random questions: - If you were not to like/love programming, would that be a serious trouble bothering your current employment? - If you were to start from the beginning, would you chose that direction this time? - What other areas (jobs or maybe hobbies) are comparable to programming in the way they can explode someone's lovely brain? - Is 'non turing-complete programming' (SQL, XML, etc.) comparable to what we do or is it really way easier, less requiring, cheap and akin to cooking :)? Well, the essence is: How would you describe programming activity WRT to its difficulty? Or, on the other hand: Did you ever catch yourself thinking at some point: OMG, it's sooo hard! I don't know how would I ever program, even carried away this way and doing programming just for fun? It's very interesting to know your opinion, your'e the programmers after all. I mean much people must be exaggerating/speculating about the thing they do not really know about. But that musn't be the case here on SO :) P.S.: I'll try my best to update this post later, and you please edit it too. At least I'll get decent English in my question text :)

• c++ class member functions selected by traits

  - by Jive Dadson

  I am reluctant to say I can't figure this out, but I can't figure this out. I've googled and searched stackoverflow, and come up empty. The abstract, and possibly overly vague form of the question is, how can I use the traits-pattern to instantiate non-virtual member functions? The question came up while modernizing a set of multivariate function optimizers that I wrote more than 10 years ago. The optimizers all operate by selecting a straight-line path through the parameter space away from the current best point (the "update"), then finding a better point on that line (the "line search"), then testing for the "done" condition, and if not done, iterating. There are different methods for doing the update, the line-search, and conceivably for the done test, and other things. Mix and match. Different update formulae require different state-variable data. For example, the LMQN update requires a vector, and the BFGS update requires a matrix. If evaluating gradients is cheap, the line-search should do so. If not, it should use function evaluations only. Some methods require more accurate line-searches than others. Those are just some examples. The original version instatiates several of the combinations by means of virtual functions. Some traits are selected by setting mode bits. Yuck. It would be trivial to define the traits with #define's and the member functions with #ifdef's and macros. But that's so twenty years ago. It bugs me that I cannot figure out a whiz-bang modern way. If there were only one trait that varied, I could use the curiously recurring template pattern. But I see no way to extend that to arbitrary combinations of traits. I tried doing it using boost::enable_if, etc.. The specialized state info was easy. I managed to get the functions done, but only by resorting to non-friend external functions that have the this-pointer as a parameter. I never even figured out how to make the functions friends, much less member functions. Perhaps tag-dispatch is the key. I haven't gotten very deeply into that. Surely it's possible, right? If so, what is best practice?

• Using map/reduce for mapping the properties in a collection

  - by And

  Update: follow-up to MongoDB Get names of all keys in collection. As pointed out by Kristina, one can use Mongodb 's map/reduce to list the keys in a collection: db.things.insert( { type : ['dog', 'cat'] } ); db.things.insert( { egg : ['cat'] } ); db.things.insert( { type : [] }); db.things.insert( { hello : [] } ); mr = db.runCommand({"mapreduce" : "things", "map" : function() { for (var key in this) { emit(key, null); } }, "reduce" : function(key, stuff) { return null; }}) db[mr.result].distinct("_id") //output: [ "_id", "egg", "hello", "type" ] As long as we want to get only the keys located at the first level of depth, this works fine. However, it will fail retrieving those keys that are located at deeper levels. If we add a new record: db.things.insert({foo: {bar: {baaar: true}}}) And we run again the map-reduce +distinct snippet above, we will get: [ "_id", "egg", "foo", "hello", "type" ] But we will not get the bar and the baaar keys, which are nested down in the data structure. The question is: how do I retrieve all keys, no matter their level of depth? Ideally, I would actually like the script to walk down to all level of depth, producing an output such as: ["_id","egg","foo","foo.bar","foo.bar.baaar","hello","type"] Thank you in advance!

• Call to undefined function 'Encrypt' - Attempting to Link OMF Lib

  - by Changeling

  I created a DLL using Visual Studio 2005 VC++ and marked a function for export (for testing). I then took the .LIB file created, and ran it through the COFF2OMF converter program bundled with Borland C++ Builder 5 and it returns the following: C:\>coff2omf -v -lib:ms MACEncryption.lib MACEncryption2.lib COFF to OMF Converter Version 1.0.0.74 Copyright (c) 1999, 2000 Inprise Corporat ion Internal name Imported name ------------- ------------- ??0CMACEncryptionApp@@QAE@XZ ?Decrypt@CMACEncryptionApp@@QAEXXZ Encrypt Encrypt@0 I added the MACEncryption2.lib file to my C++ Builder 5 Project by going to Project-Add to Project.. and selecting the library. The application links, but it cannot find the Encrypt function that I am declaring for export as follows in the VC++ code: extern "C" __declspec(dllexport) BSTR* __stdcall Encrypt() { CoInitialize(NULL); EncryptionManager::_EncryptionManagerPtr pDotNetCOMPtr; HRESULT hRes = pDotNetCOMPtr.CreateInstance(EncryptionManager::CLSID_EncryptionManager); if (hRes == S_OK) { BSTR* str = new BSTR; BSTR filePath = (BSTR)"C:\\ICVER001.REQ"; BSTR encrypt = (BSTR)"\"test"; pDotNetCOMPtr->EncryptThirdPartyMessage(filePath, encrypt, str); return str; } return NULL; CoUninitialize (); } C++ Builder Code: __fastcall TForm1::TForm1(TComponent* Owner) : TForm(Owner) { Encrypt(); } (Yes I know I am encapsulating another DLL.. I am doing this for a reason since Borland can't 'see' the .NET DLL definitions) Can anyone tell me what I am doing wrong so I can figure out why Builder cannot find the function Encrypt() ?

• How to calculate point along a curve?

  - by Nicros

  I am writing a custom animation for wpf and as a non math guy I have a couple questions... If I am given two Point3D's, the From and To, and assuming the origin is at 0,0,0 how do I calculate a curve between the two points? And once I have the curve 'plotted' and I know its length (how to do that too?) how can I calculate the x,y,z coords at some given distance along the line? Thanks!

• Customizing orchard theme parts

  - by madcapnmckay

  Hi, I am trying to write a custom theme for orchard and am not having much success so far. I have read Bertrand Le Roy's article on part alternates but I can't seem to get it to work. I am displaying a list of recent blog posts on the front page, pretty standard. I wish to change the markup produced by the meta data part i.e the time format. I have written a IShapeTableProvider to create blog specific alternates for the metadata summary part. public class MetaDataShapeProvider : IShapeTableProvider { private readonly IWorkContextAccessor workContextAccessor; public MetaDataShapeProvider(IWorkContextAccessor workContextAccessor) { this.workContextAccessor = workContextAccessor; } public void Discover(ShapeTableBuilder builder) { builder .Describe("Parts_Common_Metadata_Summary") .OnDisplaying(displaying => { ContentItem contentItem = displaying.Shape.ContentItem; if (contentItem != null) displaying.ShapeMetadata.Alternates.Add("Metadata__" + contentItem.ContentType); }); } } This is being caught correctly but the contentItem is null. Should I just create an alternate with a fixed name like "Metadata-BlogPost" and use that, to make this general purpose it should really be a dynamic name so I can use another alternate template elsewhere. Thanks, Ian

  how to read an arraylist from a txt file in java? my arraylist is the form of: public class Account { String username; String password; } i managed to put some "Accounts" in the a txt file, but now i don't know how to read them. this is how my arraylist look in the txt file: username1 password1 | username2 password2 | etc this is a part of the code i came up with, but it doesn't work. it looks logic to me though... :) . public static void RdAc(String args[]) { ArrayList<Account> peoplelist = new ArrayList<Account>(50); int i,i2,i3; String[] theword = null; try { FileReader fr = new FileReader("myfile.txt"); BufferedReader br = new BufferedReader(fr); String line = ""; while ((line = br.readLine()) != null) { String[] theline = line.split(" | "); for (i = 0; i < theline.length; i++) { theword = theline[i].split(" "); } for(i3=0;i3<theline.length;i3++) { Account people = new Account(); for (i2 = 0; i2 < theword.length; i2++) { people.username = theword[i2]; people.password = theword[i2+1]; peoplelist.add(people); } } } } catch (IOException ex) { System.out.println("Could not read from file"); } }

• What is an XYZ-complete problem?

  - by TheMachineCharmer

  EDIT: Diagram: http://www.cs.umass.edu/~immerman/complexity_theory.html There must be some meaning to the word "complete" its used every now and then. Look at the diagram. I tried reading previous posts about NP- My question is what does the word "COMPLETE" mean? Why is it there? What is its significance? N- Non-deterministic - makes sense' P- Polynomial - makes sense but the "COMPLETE" is still a mystery for me.

There is a drastic difference in the way each browser is rendering fonts. for instance, I took screenshots of what I am seeing here on stackoverflow... http://twitpic.com/q43eh I have verified that this is a trend via my co-workers machines. has anyone noticed this or have any thoughts on non-hack solutions?

• Is it a good idea to mock/stub in integration tests?

  - by ez

  Say there are multiple requests in a integration test, some of them are sphinx calls(locator for example). Should we just stub out the entire response of these sphinx call, or, since it is a integration test, we want to excise the entire test without stubbing. If that is the case, how do we still keep test independent in the situation when sphinx fails, no internet connection, or third party server non-responsive. Give reasons. Thanks

• Authentication Error when accessing Sharepoint list via web service

  - by Joe

  I wrote a windows service a few months ago that would ping a Sharepoint list using _vti_bin/lists.asmx function GetListItemChanges. It was working fine until a few weeks ago when my company upgraded our Sharepoint instance to SP1. Now whenever my service attempts to access Sharepoint I receive an 401.1 authentication error: Error: You are not authorized to view this page You do not have permission to view this directory or page using the credentials that you supplied. Please try the following: Contact the Web site administrator if you believe you should be able to view this directory or page. HTTP Error 401.1 - Unauthorized: Access is denied due to invalid credentials. Internet Information Services (IIS) I have checked and my privileges on the site have not changed. here is the code In which I call the list: Lists listsService = new Lists(); listsService.Credentials = new NetworkCredential("UserName", "Password", "domain"); Result = listsService.GetListItemChanges("List name", null, dTime.ToString(), null); It has also been brought to my attention that basic authentication may have been disabled on our farm. I don't believe I'm using that but I may be mistaken.

• How should I handle this Optimistic Concurrency error in this Entity Framework code, I have?

  - by Pure.Krome

  Hi folks, I have the following pseduo code in some Repository Pattern project that uses EF4. public void Delete(int someId) { // 1. Load the entity for that Id. If there is none, then null. // 2. If entity != null, then DeleteObject(..); } Pretty simple but I'm getting a run-time error:- ConcurrencyException: Store, Update, Insert or Delete statement affected an unexpected number of rows (0). Now, this is what is happening :- Two instances of EF4 are running inthe app at the same time. Instance A calls delete. Instance B calls delete a nano second later. Instance A loads the entity. Instance B also loads the entity. Instance A now deletes that entity - cool bananas. Instance B tries to delete the entity, but it's already gone. As such, the no-count or what not is 0, when it expected 1 .. or something like that. Basically, it figured out that the item it is suppose to delete, didn't delete (because it happened a split sec ago). I'm not sure if this is like a race-condition or something. Anyways, is there any tricks I can do here so the 2nd call doesn't crash? I could make it into a stored procedure.. but I'm hoping to avoid that right now. Any ideas? I'm wondering If it's possible to lock that row (and that row only) when the select is called ... forcing Instance B to wait until the row lock has been relased. By that time, the row is deleted, so when Instance B does it's select, the data is not there .. so it will never delete.

• How to convert String format dates to Date format dates?

  - by Jani Bela

  I have a string with dates it looks like: "20120316 20120317 20120318" ... I store this dates in this format, but I would like to make a Date array from these numbers with the format 03/16 03/17 03/18 ... So far: String[] DailyDatasOnce2 = DatesOnce.split(" "); DailyDatasOnce = new String[DailyDatasOnce2.length]; for (int i=0;i< (DailyDatasOnce2.length) ;i++){ DailyDatasOnce[i]=DailyDatasOnce2[i]; } datumok = new Date[DailyDatasOnce.length]; for (int i=0;i< (DailyDatasOnce.length) ;i++){ SimpleDateFormat curFormater = new SimpleDateFormat("yyyyMMdd"); java.util.Date dateObj = null; java.util.Date dateObj2 = null; try { dateObj = curFormater.parse(DailyDatasOnce[i]); } catch (ParseException e) { // TODO Auto-generated catch block e.printStackTrace(); } SimpleDateFormat postFormater = new SimpleDateFormat("MM/dd"); String newDateStr = postFormater.format(dateObj); try { dateObj2 = curFormater.parse(newDateStr); } catch (ParseException e) { // TODO Auto-generated catch block e.printStackTrace(); } datumok[i] = dateObj2; } So first I make a string array with the string dates (DailyDatasOnce), maybe that first for loop is useless but i can skip it. Now I make a Date array and I want to put the dates into it. I format the dates to format I want, then I try to convert them to Date format. Until the String newDateStr it is working, I manage to change the type of the date. But I get syntax error: Type mismatch: Cannot convert from java.util.date to java.sql.data. I suspect the problem but if it is not possible, how can i do this?
