  • What's a good PHP Active Record library?

    - by Luca Matteis
    I've been using CodeIgniter for some quite time, and I've been extremely happy with its Active Record stuff. It's great to query the database with it. Recently I've started a new project and I can't use such a framework anymore. Is there a simple PHP Active Record library that does its job and gets out of the way (similar to CodeIgniter's version)?

  • [N]Hibernate Sessions

    - by Jaimal Chohan
    A silly question, perhaps, but at this time of night, StackOverFlow is my only friend. I'm playing with NHibernate and wanted to factualize these 2 statements regarding Sessions in web applications. 1) You should only ever have 1 ISessionFactory per database for the lifecycle of an application. 2) You should only have 1 ISession per HttpRequest or batch of HttpRequests (i.e. conversation) [I don't want tool or framework recommendation, just want to confirm the above]

  • My mental block - struggling to learn Objective C

    - by iqessar
    Hello people, this would be my first question after signing up! Anyway heres my question, I did Java at university and I was always told I am a good programmer. However I never pursued it as a career - I went into support and management instead. Im pretty much bored with my job, I have therefore started to learn Objective C so that I can develop apps for the iphone. I am currently watching several different Videos / Books. My problem is that when I go through the Apple documentation, although I understand most of it, sometimes I stumble. I believe that because you/we have the Apple documentation (i.e. Framework references) , everything should be clear, and therefore you should have no need to refer to a book or video (in order to learn how to use a particular class). But I alway do refer to a book and video and subsequently feel guilty as I believe the framework reference should be enough. (I therefore feel I am not up to being a programmer) I also believe that you shouldn't need example code in order to learn how to use a particular class because Apple provides documentation for each class, but AGAIN I find my self googling example code and I find my answer like that - again I feel guilty for doing this. Am I right in saying that Apple documentation is simply not clear? and that its ok to refer to a video/book or google? or forums for that matter? I have proffesional programmers who tell me that I am worrying too much and that I should get on with it and use all the resources that I have. I just cant seem to get round this mental block that I have in my head. When I start a programming project I am able to use the excellent search skills that I have to find the code I need, copy and paste it (yes I do understand it) BUT then I feel guilty telling myself that why didn't you think up the code yourself???? Therefore your not a real programmer, your just good at googling. Currently I am going through 20+ books so that I can learn most of the frameworks, syntax etc to develop iphone apps. I believe if I do this, then when I think of a project I can make it quickly. Should I read a few books, like 2-3 and then just start a project /app , and if I get stuck just google it and get the code I need? Can anybody please answer my questions?

  • NoSQL or Ehcache caching ?

    - by paddydub
    I'm building a Route Planner Webapp using Spring/Hibernate/Tomcat and a mysql database, I have a database containing read only data, such as Bus Stop Coordinates, Bus times which is never updated. I'm trying to make the app run faster, each time the application is run it will preform approx 1000 reads to the database to calculate a route. I have setup a Ehcache which greatly improves the read from database times. I'm now setting terracotta + Ehcache distributed caching to share the cache with multiple Tomcat JVMs. This seems a bit complicated. I've tried memcached but it was not performing as fast as ehcache. I'm wondering if a MongoDb or Redis would be better suited. I have no experience with nosql but I would appreciate if anyone has any ideas. What i need is quick access to the read only database.

  • Is there a pattern that allows a constructor to be called only from a specific factory and from nowh

    - by willem
    We have a class, say LegacyUserSettingsService. LegacyUserSettingsService implements an interface, IUserSettingsService. You can get an instance of the IUserSettingsService by calling our ApplicationServicesFactory. The factory uses Spring.NET to construct the concrete LegacyUserSettingsService. The trouble is that new developers sometimes do their own thing and construct new instances of the LegacyUserSettingsService directly (instead of going via the factory). Is there a way to protect the constructor of the concrete class so it can only be called from the factory? A well-known pattern perhaps? Note that the concrete class resides in a different assembly (separate from the Factory's assembly, so the internal keyword is not a solution). The factory assembly references the other assembly that contains the concrete class. Any ideas?

  • Haskell, mongodb, date

    - by r.sendecky
    How would I insert or auto insert date into mongodb from haskell? What is the best way to convert from mongo date type to haskell data type? Say, in a situation where I insert blog post records (any haskell web framework) and I want to date stamp every record automatically. How would I go about it? The question is more about type conversion and mongodb date type creation from within haskell driver.

  • Why Emacs/Vim/Textmate? Isn't Xcode good enough?

    - by ivanTheTerrible
    Hi I mostly do C++, Objective-C programming. And I found Xcode plus an auto completion/macro plugin (Completion Dictionary) quite adequate. However, all people seem to praise over their pure text editors. I tried Textmate for a bit; liked its simplicity but dislike its files/framework handling. Am I missing something here? Or, do Vim or Emacs have auto-completion as good as Xcode?

  • .NET read binary contents of .lnk file

    - by Flores
    I want to read the binary contents of a .lnk file. As long as the target of the shortcut (lnk file) exists this works fine with IO.File.ReadAllBytes(string file). BUT If the target of the shortcut does not exist (believe me I want this) the method only returns zero's. I guess this is because the OS follows the link and if it does not exist it returns zero's Is there some way to bypass the fact that the framework follows the target of the .lnk before displaying the contents of the .lnk file?

  • Run django tests from a browser

    - by phoebebright
    I'd like to provide a browser page to help non-techies run the various tests I've created using the standard django test framework. The ideal would be for a way to display all the tests found for an application with tick boxes against each one, so the user could choose to run all tests or just a selection. Output would be displayed in a window/frame for review. Anyone know of such a thing?

  • class vs structure c#

    - by Enriquev
    I'm doing course 3354 (Implementing System Types and Interfaces in the .NET Framework 2.0) and it is said that for simple classes, with members variables and functions, it is better to use a struct than a class because of overhead. I have never heard of such a thing, what is the validity of this claim?

  • Cache for large read only database recommendation

    - by paddydub
    I am building site on with Spring, Hibernate and Mysql. The mysql database contains information on coordinates and locations etc, it is never updated only queried. The database contains 15000 rows of coordinates and 48000 rows of coordinate connections. Every time a request is processed, the application needs to read all these coordinates which is taking approx 3-4 seconds. I would like to set up a cache, to allow quick access to the data. I'm researching memcached at the moment, can you please advise if this would be my best option?

  • Suggestions for open source testing tool for cloud computing

    - by vikraman
    Hi, I want to know if there is any open source testing tool for cloud computing. We have built a cloud framework with Xen, Eucalyptus, Hadoop, HBase as different layers. I am not looking at testing each of these tools separately, but i want to test them from the perspective of fitting into a cloud environment (for example scalability of xen hypervisor to handle multiple VMs). Would be great if you can suggest me some tool (open source) for the above.

  • What exactly can concrete domains be used to describe?

    - by Exander
    I have read the formal definition of a "concrete domain", but I still don't quite get it. Could someone explain it to me in simpler terms, preferably with some examples? The definition is available in Reasoning in Description Logics with a Concrete Domain in the Framework of Resolution by Ullrich Hustadt, Boris Motik, Ulrike Sattler. Page 1, Definition 1.

  • Rhino Mocks - Do we really need stubs?

    - by Marcelo Oliveira
    If it's possible to change mock behaviour in Rhino Mocks using mock.Stub().Return(), why do we need Stubs anyway? What do we lose by always using MockRepository.GenerateMock()? One big benefit of using Mocks instead of Stubs is that we will be able to reuse the same instance among all the tests keeping them cleaner and straightforward. The moq framework works in a similar way... we don't have different objects for mocks and stubs. (please, don't answer with a link to Fowler's "Mocks aren't stubs" article)
