  • 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 :)

  • Reading and writing XML over an SslStream

    - by Mark
    I want to read and write XML data over an SslStream. The data (written and read) consists of objects serialized by an XmlSerializer. I have tried the following; (left some details out for clarity!) TcpClient tcpClient = new TcpClient(server, port); SslStream sslStream = new SslStream(tcpClient.GetStream(), true, new RemoteCertificateValidationCallback(ValidateServerCertificate), null); sslStream.AuthenticateAsClient(server); XmlReader xmlReader = XmlReader.Create(sslStream,readerSettings); XmlWriter xmlWriter = XmlWriter.Create(sslStream,writerSettings); myClass c = new myClass (); XmlSerializer serializer = new XmlSerializer(typeof(myClass)); serializer.Serialize(xmlWriter, c); myClass c2 = (myClass )serializer.Deserialize(xmlReader); First of all, it appears that writing to the stream succeeds. But the XmlSerializer throws an error because of invalid XML. It appears that the first character read from the stream is '00' or a null-character. (I have googled this problem, and see a million people with the same 'problem', but no viable solution.) I can work around this 'issue' by using a StreamReader, read everything into a string and then use that string as input for another stream that the serializer can use. (Very dirty, but it works.) Second problem is, that when I try to use the same SslStream to write a second request, I do not get a response from the Reader. (The server DOES send a valid XML response though!) So the serializer.Serialize(xmlWriter, c3) works, but reading from the stream yields no results. I have tried several different classes that implement Stream. (StreamReader, XmlTextReader, etc.) Anyone has an idea how reading and writing XML data to and from an SslStream is supposed to work? Thanks in advance!

  • Proper use of HttpRequestInterceptor and CredentialsProvider in doing preemptive authentication with

    - by Preston
    I'm writing an application in Android that consumes some REST services I've created. These web services aren't issuing a standard Apache Basic challenge / response. Instead in the server-side code I'm wanting to interrogate the username and password from the HTTP(S) request and compare it against a database user to make sure they can run that service. I'm using HttpClient to do this and I have the credentials stored on the client after the initial login (at least that's how I see this working). So here is where I'm stuck. Preemptive authenticate under HttpClient requires you to setup an interceptor as a static member. This is the example Apache Components uses. HttpRequestInterceptor preemptiveAuth = new HttpRequestInterceptor() { @Override public void process( final HttpRequest request, final HttpContext context) throws HttpException, IOException { AuthState authState = (AuthState) context.getAttribute(ClientContext.TARGET_AUTH_STATE); CredentialsProvider credsProvider = (CredentialsProvider) context.getAttribute( ClientContext.CREDS_PROVIDER); HttpHost targetHost = (HttpHost) context.getAttribute(ExecutionContext.HTTP_TARGET_HOST); if (authState.getAuthScheme() == null) { AuthScope authScope = new AuthScope(targetHost.getHostName(), targetHost.getPort()); Credentials creds = credsProvider.getCredentials(authScope); if (creds != null) { authState.setAuthScheme(new BasicScheme()); authState.setCredentials(creds); } } } }; So the question would be this. What would the proper use of this be? Would I spin this up as part of the application when the application starts? Pulling the username and password out of memory and then using them to create this CredentialsProvider which is then utilized by the HttpRequestInterceptor? Or is there a way to do this more dynamically?

  • How do I send email over SMTP with SSL using Java client?

    - by Ido
    I need to send email over smtp with ssl using java client. I'm not sure how to do that. If I have my server certificate installed on my Windows machine, how do I use it? If I want it to work on a non-Windows machine, do I need to get the certificates in a different way? BTW: If the SMTP server that I use is using SSL, can I be sure that it will send the mail to the recipient using SSL?

  • Playing wav files with AudioServices in iPhone

    - by Biranchi
    Hi All, I am trying to play two .wav files in my appllication, but i am only able to play the first wav file , the second file is not at all playing. I have added the AudioToolbox framework. In my .h file i have included the Audiotoolbox.h file and has the following declarations //Beep Sound SystemSoundID soundFileObject; SystemSoundID recycleFileObject; In my .m file i am registering both the wav files as following CFURLRef soundFileURLRef = CFBundleCopyResourceURL (CFBundleGetMainBundle (),CFSTR ("Beep"),CFSTR ("wav"),NULL ); AudioServicesCreateSystemSoundID (soundFileURLRef,&soundFileObject ); CFURLRef soundFileURLRef2 = CFBundleCopyResourceURL (CFBundleGetMainBundle (),CFSTR ("Recycle"),CFSTR ("wav"),NULL ); AudioServicesCreateSystemSoundID (soundFileURLRef2,&recycleFileObject ); And i have written two methods for playing each file individually. -(void)playBeepSound { NSLog(@"Beep sound called : %d", soundFileObject); AudioServicesPlaySystemSound (soundFileObject); } -(void)playRecycleSound { NSLog(@"Recycle sound called : %d", recycleFileObject); AudioServicesPlaySystemSound (recycleFileObject); } But i am only able to play the Beep sound , but not the second sound wav file. What is the error ??? Thanks

  • How should I read from a buffered reader?

    - by Roman
    I have the following example of reading from a buffered reader: while ((inputLine = input.readLine()) != null) { System.out.println("I got a message from a client: " + inputLine); } The code in the loop println will be executed whenever something appears in the buffered reader (input in this case). In my case, if a client-application writes something to the socket, the code in the loop (in the server-application) will be executed. But I do not understand how it works. inputLine = input.readLine() waits until something appears in the buffered reader and when something appears there it returns true and the code in the loop is executed. But when null can be returned. There is another question. The above code was taken from a method which throws Exception and I use this code in the run method of the Thread. And when I try to put throws Exception before the run the compiler complains: overridden method does not throw exception. Without the throws exception I have another complain from the compiler: unreported exception. So, what can I do?

  • jQuery UI Datepicker - Disable specific days

    - by Sam
    Is there any (easy) way to set the jQuery UI Datepicker to disallow selection of specific, predetermined days? I was able to get this approach working, however, it produces a null error which prevents it from displaying in IE. 'natDays[...].0' is null or not an object Thanks in advance! UPDATE: Might help if I included some code, right? Anyway, most of this was taken straight from the aforementioned thread: natDays = [ [7, 23], [7, 24], [8, 13], [8, 14], ]; function nationalDays(date) { for (i = 0; i < natDays.length; i++) { if (date.getMonth() == natDays[i][0] - 1 && date.getDate() == natDays[i][1]) { return [false, natDays[i][2] + '_day']; } } return [true, '']; } function noWeekendsOrHolidays(date) { var noWeekend = $.datepicker.noWeekends(date); if (noWeekend[0]) { return nationalDays(date); } else { return noWeekend; } } $(function() { $("#datepicker").datepicker({ inline: true, minDate: new Date(2009, 6, 6), maxDate: new Date(2009, 7, 14), numberOfMonths: 2, hideIfNoPrevNext: true, beforeShowDay: $.datepicker.noWeekends, altField: '#alternate', }); }); Thanks again!

  • What is the Difference between GC.GetTotalMemory(false) and GC.GetTotalMemory(true)

    - by somaraj
    Hi, Could some one tell me the difference between GC.GetTotalMemory(false) and GC.GetTotalMemory(true); I have a small program and when i compared the results the first loop gives an put put < loop count 0 Diff = 32 for GC.GetTotalMemory(true); and < loop count 0 Diff = 0 for GC.GetTotalMemory(false); but shouldnt it be the otherway ? Smilarly rest of the loops prints some numbers ,which are different for both case. what does this number indicate .why is it changing as the loop increase. struct Address { public string Streat; } class Details { public string Name ; public Address address = new Address(); } class emp :IDisposable { public Details objb = new Details(); bool disposed = false; #region IDisposable Members public void Dispose() { Disposing(true); } void Disposing(bool disposing) { if (!disposed) disposed = disposing; objb = null; GC.SuppressFinalize(this); } #endregion } class Program { static void Main(string[] args) { long size1 = GC.GetTotalMemory(false); emp empobj = null; for (int i = 0; i < 200;i++ ) { // using (empobj = new emp()) //------- (1) { empobj = new emp(); //------- (2) empobj.objb.Name = "ssssssssssssssssss"; empobj.objb.address.Streat = "asdfasdfasdfasdf"; } long size2 = GC.GetTotalMemory(false); Console.WriteLine( "loop count " +i + " Diff = " +(size2-size1)); } } } }

  • 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?

  • How can I export an array from Dynamics AX 2009 via c#?

    I'm pulling data from Dynamics AX 2009 from c# using the following code snippet. This works fine, except for those cases where the underlying field type is a dimension. I want to be able to "flatten" array types when I return them but can't see any way to do this. Any ideas anyone? axRecord = ax.CreateAxaptaRecord(tableName); axRecord.ExecuteStmt(strQuery); // Loop through the set of retrieved records. using (StreamWriter sw = File.CreateText(path)) { AxaptaObject axDictTable = ax.CreateAxaptaObject("SysDictTable",axRecord.get_Field("tableid")); outputRow = null; List<int> ids = new List<int>(); for (int i = 1; i <= (int)axDictTable.Call("fieldCnt"); i++) { AxaptaObject axDictField = ax.CreateAxaptaObject("DictField", axRecord.get_Field("tableid"), axDictTable.Call("fieldCnt2ID", i)); outputRow += ((string)axDictField.Call("Name")) + ","; ids.Add((int)axDictTable.Call("fieldCnt2ID", i)); } sw.WriteLine(outputRow); while (axRecord.Found) { outputRow = null; foreach(int i in ids) outputRow += axRecord.get_Field(i).ToString().Replace(",", "") + ","; sw.WriteLine(outputRow); axRecord.Next(); } }

  • Application crashing on getting updated information from database using timer and storing it on loca

    - by Amit Battan
    In our multi - user application we are continuously interacting with database. We have a common class through which we are sending POST queries to database and obtaining xml files in return. We are using delegates of NSXMLParser to parse the obtained file. The problem with us is we are facing many crashes in it generally when application is idle and changed data in database is being fetched in background through timer which is invoked after every few seconds. We have also dealt with error handling through try and catch but it proves to be of no use in this case and mostly application crashes with following error : Exception Type: EXC_BAD_ACCESS (SIGBUS) Exception Codes: KERN_PROTECTION_FAILURE at 0x0000000000000020 Strange thing is that many times the fetching of updated data at background works very fine, same methods being successfully executed under similar conditions but suddenly it crashes on one of them. The codes we are using is as follows: // we are using timer in this way: chkOnlineUser=[NSTimer scheduledTimerWithTimeInterval:15 target:mmObject selector:@selector(threadOnlineUser) userInfo:NULL repeats:YES];

  • Macbook memory upgrade question

    - by James Evans
    I've read some conflicting articles on Macbooks and memory upgrades. Some say you have to buy the "special" Mac memory (bulls$%t), others say manufacturers like Partriot and Ocz will work fine. My Macbook (non-pro) is about 6 mos old with it's 2 GB of memory (SO-DIMM 1066MHz DDR3). Does anyone have any definitive information of what will work? Thanks!

  • Checklist for Launching public beta

    - by Vinayak
    I am developing a web app that is about to be opened for public beta. Does anyone know of or has prepared a checklist of the various steps that one needs to take to ensure a smooth beta implementation? The web app is coded using Java, MySQL on the server side and HTML, Javascript on the client side with a little Flash in one or two screens. I know this question is very non-specific, but I am looking for best practices/guidelines here. Thanks in advance.

If not, how have folks out there been creating Android versions of their existing iPhone apps? Thanks
