  • Why did Matz choose to make Strings mutable by default in Ruby?

    - by Seth Tisue
    It's the reverse of this question: http://stackoverflow.com/questions/93091/why-cant-strings-be-mutable-in-java-and-net Was this choice made in Ruby only because operations (appends and such) are efficient on mutable strings, or was there some other reason? (If it's only efficiency, that would seem peculiar, since the design of Ruby seems otherwise to not put a high premium on faciliating efficient implementation.)

  • Ninject and DataContext disposal

    - by Bas
    I'm using Ninject to retrieve my DataContext from the kernel and I was wondering if Ninject automatically disposes the DataContext, or how he handles the dispose() behaviour. From own experiences I know disposing the datacontext is pretty important and that whenever you create a direct object of the DataContext (as in: new DataContext()) you should use a using() block. My question thus is: When im retrieving my DataContext from the kernel, should I still have to use a using() block? Or does Ninject fix this for me?

  • Testing the context in asp.net mvc

    - by user252160
    I got pretty experienced with testing controllers, my question here is though, aren't we supposed to test the data context as well, and how ? I mean, there are a lot of relationships and constraints coming from the DB that simply testing controllers does not cover. On the other hand, testing against the DB is not considered a good practice - what then ? Simply testing without db.SubmitChanges() or what ?

  • Matrices of "long"s in Java/COLT?

    - by Darren Wilkinson
    I'm very new to Java/COLT so apologies if this is a dumb question... But, is it possible to define (2d) matrices of type "long" using the cern.colt.matrix stuff? If so, how?! I can find an abstract class for "Object" and a concrete implementation for "double", but then I am stuck... Thanks,

    I am trying use the following regression to extract domain name from a text, but it just produce nothing, what's wrong with it? I don't know if this is suitable to ask this "fix code" question, maybe I should read more. I just want to save some time. Thanks pat_url = re.compile(r''' (?:https?://)* (?:[\w]+[\-\w]+[.])* (?P<domain>[\w\-]*[\w.](com|net)([.](cn|jp|us))*[/]*) ''') print re.findall(pat_url,"http://www.google.com/abcde") I want the output to be google.com

  • What's the difference between isPrototypeOf and intanceof in Javascript?

    - by Steffen Heil
    Hi In some of my own older code, I use the following: Object.prototype.instanceOf = function( iface ) { return iface.prototype.isPrototypeOf( this ); }; Then I do (for example) [].instanceOf( Array ) This works, but it seems the following would do the same: [] instanceof Array Now, surly this is only a very simple example. My question therefor is: Is a instanceof b ALWAYS the same as b.prototype.isPrototypeOf(a) ? Regards, Steffen

  • How can Swing dialogs even work?

    - by Bart van Heukelom
    If you open a dialog in Swing, for example a JFileChooser, it goes somewhat like this pseudocode: swing event thread { create dialog add listener to dialog close event { returnValue = somethingFromDialog } show dialog (wait until it is closed) return returnValue } My question is: how can this possibly work? As you can see the thread waits to return until the dialog is closed. This means the Swing event thread is blocked. Yet, one can interact with the dialog, which AFAIK requires this thread to run. So how does that work?

  • Extraneous Library Linkage

    - by gmatt
    I have a question which may be somewhat silly because I'm pretty sure I may know the answer already. Suppose you have static library A, and dynamic shared object library B and your program C under linux. Suppose that library A calls functions from library B and your program calls functions from library A. Now suppose that all functions that C calls in A make no use of functions in B. To compile C will it be enough to link just A and omit B and furthermore can your program C be run on a system without library B installed?

  • Reading Source Code Aloud

    - by Jon Purdy
    After seeing this question, I got to thinking about the various challenges that blind programmers face, and how some of them are applicable even to sighted programmers. Particularly, the problem of reading source code aloud gives me pause. I have been programming for most of my life, and I frequently tutor fellow students in programming, most often in C++ or Java. It is uniquely aggravating to try to verbally convey the essential syntax of a C++ expression. The speaker must give either an idiomatic translation into English, or a full specification of the code in verbal longhand, using explicit yet slow terms such as "opening parenthesis", "bitwise and", et cetera. Neither of these solutions is optimal. On the one hand, an idiomatic translation is only useful to a programmer who can de-translate back into the relevant programming code—which is not usually the case when tutoring a student. In turn, education (or simply getting someone up to speed on a project) is the most common situation in which source is read aloud, and there is a very small margin for error. On the other hand, a literal specification is aggravatingly slow. It takes far far longer to say "pound, include, left angle bracket, iostream, right angle bracket, newline" than it does to simply type #include <iostream>. Indeed, most experienced C++ programmers would read this merely as "include iostream", but again, inexperienced programmers abound and literal specifications are sometimes necessary. So I've had an idea for a potential solution to this problem. In C++, there is a finite set of keywords—63—and operators—54, discounting named operators and treating compound assignment operators and prefix versus postfix auto-increment and decrement as distinct. There are just a few types of literal, a similar number of grouping symbols, and the semicolon. Unless I'm utterly mistaken, that's about it. So would it not then be feasible to simply ascribe a concise, unique pronunciation to each of these distinct concepts (including one for whitespace, where it is required) and go from there? Programming languages are far more regular than natural languages, so the pronunciation could be standardised. Speakers of any language would be able to verbally convey C++ code, and due to the regularity and fixity of the language, speech-to-text software could be optimised to accept C++ speech with a high degree of accuracy. So my question is twofold: first, is my solution feasible; and second, does anyone else have other potential solutions? I intend to take suggestions from here and use them to produce a formal paper with an example implementation of my solution.

  • JavaScript - Why does google-maps wait until jquery finishes download?

    - by Teddyk
    I'm using the following Google Maps autload (asynchronous) to load asynchronous both Google Maps v3 and JQuery, like so: <script type="text/javascript" src="http://www.google.com/jsapi?autoload={ "modules":[ {name:"maps",version:3,other_params:"sensor=false"},{"name":"jquery","version":"1.4.2"},{"name":"jqueryui","version":"1.8.1"} ]}"></script> However, looking at the network traffic, it appears that it is not downloading asynchronously. Question: Does anyone understand why the %7Bcommon (google-maps) file is being delayed from download until the jquery-ui.min file completes download first?

  • Python Mechanize select a form with no name

    - by mvid
    I am attempting to have mechanize select a form from a page, but the form in question has no "name" attribute in the html. What should I do? when I try to use br.select_form(name = "") i get errors that no form is declared with that name, and the function requires a name input. There is only one form on the page, is there some other way I can select that form?

  • Impact of Multiple .ToUpper()'ing

    - by Kyle Rozendo
    Hi All, This is not a question of premature optimization per se. On the garbage collector and memory in general, what would hundreds of ToUpper() operations (many could be duplicated) do to a program, mainly in regard to the immutability of strings? Thanks, Kyle

  • method names with fluent interface

    - by deamon
    I have a Permissions class with methods in fluent style like this: somePermissions.setRead(true).setWrite(false).setExecute(true) The question is, whether I should name these methods set{Property} or only {property}. The latter would look like this: somePermissions.read(true).write(false).execute(true) If I look at these methods separately I would expect that read reads something, but on the other hand it is closer to the intention to have something like named paramaters like in Scala: Permission(read=true, write=false, execute=true)

  • Is simply upvoting the best answers to old questions the best way to get them off the unaswered list

    - by Cade Roux
    While the answers might not be the best or the question really doesn't have an answer, if none are upvoted or the person doesn't accept an answer, they sit and sit in the unanswered page. In cases which do have realistic answers, I've been voting up the best. Even if I combine the best answers into a better one, the questioners aren't upvoting, accepting or closing the questions anyway.

  • client-side synchronous service invocation

    - by qkrsppopcmpt
    I am talking about synchronous on the client side. That means, the service requester is blocking after sending a message to the service. my question is: is it related to the -a -s parameter of wsdl2java tool, Since -a generate async style code and -s generate sync style code. Or the client side blocking or not is totally controlled by the client logic? Thanks

  • why aren't interfaces [Serializable]?

    - by Zac Harlan
    I would think that adding that attribute to an interface would be helpful make sure you don't create classes that use the interface and forget to make them serializable. This could be a very fundamental question but wanted to ask the experts. Thanks in advance. Zac

  • C# - Regular Expression validating Date and Hour

    - by nettguy
    I receive Date and time from CSV file The received Date format is YYYMMDD (string) (there is no ":" ,"-","/" to separate Year month and date). The received time format is HH:MM (24 Hour clock). I have to validate both so that (example) (i) 000011990 could be invalidated for date (ii) 77:90 could be invalidated for time. The question is , Regular expression is the right candidate for do so (or) is there any other way to achieve it?
