  • As a programmer, how much time do you spend churning?

    - by Chinnery
    I recently went through a period of frustration, "churning" as I tried to set up my environment to work effectively on a task. By the time I broke through and started to make actual progress, I felt tired and kind of angry. (I'll admit: in this case, it took me several days of banging my head and ultimately starting from scratch to finally get around the problems.) This experience made me wonder: When a roadblock happens to other programmers, how long do they churn before finally becoming productive and beginning what feels like actual work?

  • Is there a way to visualize records stored in an iPhone app via Core Data?

    - by Justin Searls
    I have an app which, for good reasons, can only be debugged on a device. I'm using Core Data for the first time, and I'd like to be able to easily inspect the records that are stored by the app on the device. I imagine that Core Data is by default backed by SQLite on the iPhone, so this question might be as simple as asking: "What's the easiest way to extract the SQLite database for an app installed by Xcode without jailbreaking it?" Any experience someone could lend regarding this would be greatly appreciated.

  • Best Embedded SQL DB for write performance?

    - by max.minimus
    Has anybody done any benchmarking/evaluation of the popular open-source embedded SQL DBs for performance, particularly write performance? I've some 1:1 comparisons for sqlite, Firebird Embedded, Derby and HSQLDB (others I am missing?) but no across the board comparisons... Also, I'd be interested in the overall developer experience for any of these (for a Java app).

  • unique selling points: php, flash, rails

    - by pwebdev
    on reflecting how to talk with prospect customers on technologies for web applications, what are important requirements for chosing a specific technology? I am biased towards ruby on rails, but the code base and community of PHP is larger, while the user experience of flash sites is often an advantage to the segment of higher paying customers. how would you argue for or against the usage of a technology in general? for ruby on rails in particular?

  • Zend_Search_Lucene vs SOLR

    - by spacemonkey
    Hi, I have recenlty stumbled into Zend Lucene port of Lucene project. I have a little bit experience with SOLR so I would like to know what is the difference between two of them especially from performance and installation side. As much as I know SOLR requires Tomcat serverlet running in web hosting in order to work, what about Zend Lucene library? I am also a bit confused what means "being implemented on the top of Lucene"?

  • When would you choose C# over F#? [closed]

    - by Rosdi
    Possible Duplicate: What are the benefits of using C# vs F# or F# vs c#? There are a lot of general questions comparing functional programming vs object oriented. But I need to know the advantageous of F# over C#. Assuming you have the same skill/experience/expertise in both C# and F#, and there are no other constraints (time, team skills, etc) when would you choose C# over F# (or vice-verse)?**

  • .net - invoke methods from classes from a certain namespace via reflection

    - by Kristian Hildebrandt
    SPL and PHP allows you to create objects on the fly from classes, that fulfill certain conditions, such as implementing certain interfaces and stuff like that. However, I would like to do something similar in c# and automatically create objects from all classes in a namespace and invoke a particular method from those classes that implement a certain interface. My experience developing desktop apps is very limited. I am not quite sure if I should use delegates to archive this or if reflection is really the way to go.

  • Relational Database arrays (H2, Java)

    - by Daddy Warbox
    I seem to have two options on how to implement arrays, and I want to know which I should go with: Use the ARRAY data type and (from what I understand) effectively serialize data objects into the database (which in my case are just wrapped primitive types; don't know of another way to make this work). Use a separate table and map with foreign keys for each array item. If you have experience with this (especially with H2), which would you recommend?

  • writing a shell script if statement to check for directory

    - by user1553248
    I need to write a script that will recreate my opt folder if it gets deleted when I remove a package from it. Here's a link to my previous post: dpkg remove to stop processes Now, the issue I'm running into could be better described here: http://lists.debian.org/debian-devel/2006/03/msg00242.html I was thinking of just adding a postrem script which checks if an opt directory exists, and if not, creates one. My experience with shell scripts is pretty limited though..

  • Switching to Java from C++: What are the key points?

    - by Roddy
    I'm an experienced developer, but most of my OO programming experience has been with C++ (and a little Delphi). I'm considering doing some Android work, hence Java. Coming from the C++ background, what areas of Java are most likely to surprise/annoy/delight me? I felt sure this would already have been asked, but my searches haven't turned up a similar question. CW, of course.

  • Adding C++ DLL's to a C# project

    - by WebDevHobo
    I'm trying to use the lame_enc.dll file from LAME in a C# project, but adding the thing seems impossible. I keep getting an error that says that a reference could not be added and to please check if the is accessible, a valid assembly or COM component. I have no C++ experience, though I would like to use the functionality. Right now I'm using Process from the .NET framework to call lame.exe and do stuff, but I'd like to know if there's another way.

Update: Maybe I can copy-paste code of some existing joomla comments component in my own component? Does somebody tried to do this?

  • .net compliant version control system that can be installed on a shared hosting (with no SSH/root Access)

    - by Farshid
    I searched a lot in SO and other websites for a version control system that can be installed on a shared windows hosting that lets me create repositories for putting my project files on it and supply me with version control facilities but I did not find one. I looked to see whether I can install git, Mercurial or TFS in a shared hosting and I did not found any answer. I want to know if you know any system that can be installed on a shared windows hosting and please tell your recommendations if you have had an experience before.

  • A simple, clean web layout

    - by Shaun_web
    Ok, so I hate CSS/HTML graphic design... What do you guys recommend as a sample template or website that you think has great CSS and html layout? From my past experience it's best to get a page that has a white background and little dependency on graphics -- that's clean, and easy to modify ;-).

  • Has anyone been able to install Retrospectiva on a Windows machine?

    - by H1Man
    I've been looking into some bug trackers and Retrospectiva seems like a good tool. However, I am having all sorts of trouble installing it on my machine. I followed the guide on their site (http://retrospectiva.org/tickets/357) but it hasn't helped much and there don't seem to be a lot of users on their site that work with Windows. I am wondering if any of the SO users have any experience working with Retrospectiva.

  • Good or Bad experiences with CryptoLicensing?

    - by dr. evil
    I'm planning to buy CryptoLicensing but before buying it I'd like to get some feedbacks if anyone tried it before. Also it'd be interesting if anyone cracked it or spotted an easy hack against it. I've seen some other SO questions regarding the choosing a .NET licensing component but if you currently happy with another component it'd be nice to hear your experience. It's just quite hard to nail this without going through a long trial.

  • What's the Erlang/Haskell job market like in the U.S.?

    - by Krystof
    I've heard that Telecoms are the big source of Erlang jobs but I'm not sure how much of a market there is. How likely is it that someone could find a job in Erlang/Haskell if they decided to learn it? In my case I have a lot of programming experience in Java but am tired of Java and want to try something different.
