  • What are the things Java got wrong?

    - by Alon
    I read a lot of blogs and see people all the time talking about bad things in the java programming language; a lot of them are about annotations and generics that were added to the language in 1.5 release. What are the things in the language or the API that you don't like or would design differently?

  • Will Haskell be a good choice for my task?

    - by Narzanka
    I'm starting a new project and don't know which language to use. My 'must have' requirements are: Be able to run on Windows/LinuxMacOs natively (native executable) - user should be able to just run the exe (when on Windows for example) and see the results. No runtimes/interpreters (no jvm, clr, etc) - one file download should be enough to run the application. Full unicode support. Be able to manipulate OS threads (create them, run multiple tasks in parallel on multi-core CPUs, etc). Be reasonably fast (Python level performance and better). To have some kind of standard library that does low-level, mundane tasks. Not very niche and have some community behind it to be able to ask questions. My 'nice to have' requirements are: Language should be functional It should have good string manipulation capabilities (not necessarily regex) Not extremely hard to learn I'm thinking about Haskell now but keeping in mind OCaml as well. Please advice if my choice is correct.

  • 20 lines of code you're working on right now [closed]

    - by Anton Gogolev
    Out of sheer curiosity. Hope none of you NDAs are violated or whatever. Here are mine. I'm currently refactoring a massively coupled webapp. As it usually is, no comments and no documentation whatsoever. if (paymentMethod == PaymentMethod.InAgency ) { EmailController.SendBookingCreateEmails(booking); this.DC.SubmitChanges(); return RedirectToAction("Result", new { id = booking.Id }); } else if (paymentMethod == PaymentMethod.CreditCard) { return RedirectToAction("Pay", new { id = booking.Id }); } else if(paymentMethod == PaymentMethod.MostravelBank || paymentMethod == PaymentMethod.MostravelCallback || paymentMethod == PaymentMethod.MostravelCardCredit || paymentMethod == PaymentMethod.MostravelCourierCash || paymentMethod == PaymentMethod.MostravelCourierPlasticCard) { isExclusive = true; Log.TraceInformation("Started booking for Mostravel. Payment method: {0}", paymentMethod); try { Log.TraceInformation("Sending emails"); EmailController.SendBookingCreateEmailsEx(booking); Log.TraceInformation("Sent emails. Started booking"); MakeRealBooking(booking, DC.MailRuAgencies.First(a => a.Id == MvcApplication.DefaultMailRuAgencyId)); Log.TraceInformation("Finished booking"); } catch(Exception ex) { Log.TraceEvent(TraceEventType.Error, 0, "Error while booking: {0}", ex.ToString()); } What are you working on right now?

  • Switching from php to python

    - by ts
    Hello I am trying to make a list of things which can be difficult/surprising to someone who is changing language from PHP to Python. so far i have rather short list: forget require / include, learn import (this was most difficult to me - to understand package - module - class - object hierarchy and its mapping to filesystem) you can't just upload file on server to have webpage (-mod_python, wsgi etc) learn the python way for use variable class names (new $class() vs import + getattr) / operator in python 2.x and all float-related horrors those were difficult to me, it takes few days before mind adapts a new paradigm after i found that there is few other areas which could be challenging for someone with (too) many years of php: everything is an object you have to live with exceptions array vs list, set, dictionary, tuple ... learn (effective) list comprehensions learn generators any other ideas / personal experiences ?

  • Impressing Potential Employers

    - by superfly123
    Where I am, I can't afford to get certification. I'm definitely not the best programmer, but I do know my junk. I've been writing software in C++ for over 8 years now and have a very good knowledge of the Win32 API. But when applying for jobs, I get rejected every time I send a resume. I've given my resume to recruitment firms and asked them what they think's wrong with it and they said the only thing they could think of is the fact that I don't have certifications to prove that I know my stuff. But in my resume, I explain my previous work and projects, and also note that upon request they can actually see what I've done. Is there anything that you would suggest that might help others to stop ignoring my resumes? Thank you

    - by EquinoX
    I know there's a lot of resource for this via google, but I just wanted to hear personally from people who have experienced this before. I've programmed in C for 3 years and C++ for a year and now I am moving to C#. I know this is not going to be a so hard transition but could you guys that had this same experience with me share resources on a good book, article, or blog to make my study experience more efficient. Any tips/tricks or gotchas when moving to C#? Here's one article that I can find via google. Looking for more goodies from experienced developers here.
