  • whats the best way to parse and replace the string with its values ?

    - by shahjapan
    I may have string like, """Hello, %(name)s, how are you today, here is amount needed: %(partner_id.account_id.debit_amount)d """ what would be the best solution for such template may i need to combine regular expression and eval, input string may differ like $partner_id.account_id.debit_amount$ - for the moment I've kept as python string format - just for testing.

  • Passing a hostname of over 255 characters to getaddrinfo causes a getaddrinfo failed: memory allocat

    - by darrickc
    I am currently upgrading our software to support ipv6 and in the meantime I'm expanding hostname/ip fields to the max hostname size. In sun documentation it seems like this can be up to 1025 (netdb.h:#define NI_MAXHOST 1025 - this is the recommended hostname allocation define), but when I pass a hostname of over 255 to getaddrinfo I get "getaddrinfo failed: memory allocation failure". I am testing on a Sol10 box. Ideas?

  • Tuning garbage collections for low latency

    - by elec
    I'm looking for arguments as to how best to size the young generation (with respect to the old generation) in an environment where low latency is critical. My own testing tends to show that latency is lowest when the young generation is fairly large (eg. -XX:NewRatio <3), however I cannot reconcile this with the intuition that the larger the young generation the more time it should take to garbage collect. The application runs on linux, jdk 6 before update 14, i.e G1 not available.

  • Put a java socket-like program in a cloud service

    - by user293030
    I developed a server side java program, basically is a relay server so I can easily pass NATs and firewalls. The program works, but now I need a cloud service to host it. Do you know where/how I can put a java socket-like program in the cloud? Obviously, I prefer a free service or at least a free service while I'm testing. Thank you!

  • Simple WCF service with REST - Resource cannot be found - error with ASP.NET Debug Server?

    - by lesasch
    Hi, I'm testing a very simple WCF-Service with REST functionality enabled. It works fine on IIS, but the VS2010 debug webserver always says "The resource cannot be found" when appending the parameter after the .svc file in the browser uri. Is this a known issue with the asp.net debug webserver that it cannot work with REST or am I doing anything wrong? (again: with IIS, it works)

  • opensourcing a website code

    - by pygabriel
    Hi! I'm writing a little website (webapp) in php+codeigniter, I'd really like to make it open source (to attract collaborators and to have a free VCS hosting). Is that a good practice? This mine security? Which are the best tools to change important data before uploading? (like config files with db names and passwords used for testing etc..)

  • Parallel Dev: Should developers work within the same branch?

    - by Zombies
    Should multiple developers work within the same branch, and update - modify - commit ? Or should each developer have his/her own each branch exclusively? And how would sharing branches impact an environment where you are doing routine maintenance as opposed to unmaintained code streams? Also, how would this work if you deploy each developers work as soon as it is done and passes testing (rapidly, as opposed to putting all of their work into a single release).

  • Simple prolog program. Getting error: >/2: Arguments are not sufficiently instantiated

    - by user1279812
    I made a prolog program posAt(List1,P,List2) that tests whether the element at position P of List1 and List2 are equal: posAt([X|Z],1,[Y|W]) :- X=Y. posAt([Z|X],K,[W|Y]) :- K1, Kr is K - 1, posAt(X,Kr,Y). When testing: ?- posAt([1,2,3],X,[a,2,b]). I expected an output of X=2 but instead I got the following error: ERROR: /2: Arguments are not sufficiently instantiated Why am I getting this error?

  • How to choose between UUIDs, autoincrement/sequence keys and sequence tables for database primary keys?

    - by Tim
    I'm looking at the pros and cons of these three primary methods of coming up with primary keys for database rows. So assuming I am using a database that supports more than one of these methods, is there a simple heuristic to determine what the best option would be for me? How do considerations such a distributed/multiple masters, performance requirements, ORM use, security and testing have on the choice? Any unexpected drawbacks that one might run into?

  • Start to Finish Advanced Project Tutorials

    - by Ronnie Overby
    Can anyone recommend some start to finish project tutorials that really emphasize good design principles and best practices. I am looking for things that demonstrate and emphasize any or all of these: Domain Driven Design Unit Testing Inversion of Control Separation of Concerns Use of interfaces Object Relational Mapping Preferably ASP.NET MVC I am currently watching the Autumn of Agile series, which demonstrates many of these principles. I would like to find more of these tutorials/demos.

  • True / false evaluation doesn't work as expected in Scheme

    - by ron
    I'm trying to compare two booleans : (if (equal? #f (string->number "123b")) "not a number" "indeed a number") When I run this in the command line of DrRacket I get "not a number" , however , when I put that piece of code in my larger code , the function doesn't return that string ("not a number") , here's the code : (define (testing x y z) (define badInput "ERROR") (if (equal? #f (string->number "123b")) "not a number" "indeed a number") (display x)) And from command line : (testing "123" 1 2) displays : 123 Why ? Furthermore , how can I return a value , whenever I choose ? Here is my "real" problem : I want to do some input check to the input of the user , but the thing is , that I want to return the error message if I need , before the code is executed , because if won't - then I would run the algorithm of my code for some incorrect input : (define (convert originalNumber s_oldBase s_newBase) (define badInput "ERROR") ; Input check - if one of the inputs is not a number then return ERROR (if (equal? #f (string->number originalNumber)) badInput) (if (equal? #f (string->number s_oldBase)) badInput) (if (equal? #f (string->number s_newBase)) badInput) (define oldBase (string->number s_oldBase)) (define newBase (string->number s_newBase)) (define outDecimal (convertIntoDecimal originalNumber oldBase)) (define result "") ; holds the new number (define remainder 0) ; remainder for each iteration (define whole 0) ; the whole number after dividing (define temp 0) (do() ((= outDecimal 0)) ; stop when the decimal value reaches 0 (set! whole (quotient outDecimal newBase)) ; calc the whole number (set! temp (* whole newBase)) (set! remainder (- outDecimal temp)) ; calc the remainder (set! result (appending result remainder)) ; append the result (set! outDecimal (+ whole 0)) ; set outDecimal = whole ) ; end of do (if (> 1 0) (string->number (list->string(reverse (string->list result))))) ) ;end of method This code won't work since it uses another method that I didn't attach to the post (but it's irrelevant to the problem . Please take a look at those three IF-s ... I want to return "ERROR" if the user put some incorrect value , for example (convert "23asb4" "b5" "9") Thanks
