  • What's the best way to migrate a Django DB from SQLite to MySQL?

    - by Inshim
    I need to migrate my db from sqlite to mysql, and the various tools/scripts out there are too many for me to easily spot the safest and most elegant solution. This seemed to me nice http://djangosnippets.org/snippets/14/ but appears to be 3 years since getting an update which is worrying.. Can you recommend a solution that is known to be reliable with Django 1.1.1 ?

  • How should I begin to help projects in Github?

    - by Erik Escobedo
    I'm new to github and I like to help other people with his projects that I find interesting. I know there's a lot of guides in the github place, but I think it could be nice to gather a bunch of real people's experiences. So, I invite you to post about your first experiences in github. Whether you are a not-so-newbie or you are a heavy rock in github comunnity, I think your lines could encourage real newbies like me about entering this great open source community.

  • linq to sql loadwith vs associatewith

    - by stackoverflowuser
    what is the difference between loadwith and associatewith. From the articles i read it seems that loadwith is used to load addition data (eg all orders for the customers). While AssociateWith is used to filter data. Is that a correct understanding? Also it will be nice if someone can explain this with an example based explanation.

  • Code Contracts Vs. Object Initializers (.net 4.0)

    - by Mystagogue
    At face value, it would seem that object initializers present a problem for .net 4.0 "code contracts", where normally the invariant should be established by the time the object constructor is finished. Presumably, however, object-initializers require properties to be set after construction is complete. My question is if the invariants of "code contracts" are able to handle object initializers, "as if" the properties were set before the constructor completes? That would be very nice indeed!!

  • How to add some non standard font to website?

    - by vaske
    Is there any way to add some custom font on website without using images, flash or some other graphics. For example, I was working on some wedding website, and I was found a lot of nice fonts for that subject, but I can't find the right way to add that font on the server, and how to include that font with css into the html. Is this possible to do without graphics?

  • How does the hash part in hash maps work?

    - by sub
    So there is this nice picture in the hash maps article on Wikipedia: Everything clear so far, except for the hash function in the middle. How can a function generate the right index from any string? Are the indexes integers in reality too? If yes, how can the function output 1 for John Smith, 2 for Lisa Smith, etc.?

  • How to allow resizing of QMessageBox in PyQt4

    - by Simeon Fitch
    I'm using the nice feature in QMessageBox to optionally show detailed text to the user. However, the window after expansion is still fairly small, and one immediately tries to resize the window so more of the details are visible. Even after setting what I think are the proper settings it won't allow resizing. Here's the relevant snippet of PyQt4 code: mb = QMessageBox() mb.setText("Results written to '%s'" % filename) mb.setDetailedText(str(myData)) mb.setSizePolicy(QSizePolicy.Expanding, QSizePolicy.Expanding) mb.setSizeGripEnabled(True) Am I missing a step and/or is this at all possible?

  • Is it possible to have all "git diff" commands use the "Python diff", in all git projects?

    - by EOL
    When including the line *.py diff=python in a local .gitattributes file, git diff produces nice labels for the different diff hunks of Python files (with the name of the function where the lines changed take place, etc.). Is is possible to ask git to use this diff mode for all Python files across all git projects? I tried to set a global ~/.gitattributes, but it is not used by local git repositories. Is there a more convenient method than initializing each new git project with a ln -s ~/.gitattributes?

  • Custom description page for the WCF endpoint?

    - by Joannes Vermorel
    I am migrating an ASP.NET Web Service toward WCF. The old Web Service endpoint had a nice extensive description page generated from the comment of the underlying class exposed as a service endpoint. In particular, all available web methods were listed. Is there a way to emulate somehow this behavior with WCF? At least, how can I customize the HTML content of the WCF endpoint?

  • What's the best way of playing media files (esp. audio) with Mono/C#?

    - by supercheetah
    I'm trying to create something that will be playing some sound and music for some things in Mono+C#, but I'm not sure what the best thing will be for that. I'm trying to make it usable with things like Ogg Vorbis, MP3s, and wave files. My primary platform will be Linux, although a cross platform solution would be nice. Anyone have any suggestions for libraries for playing audio files?

  • Can you set SQL Server permissions from a Silverlight app?

    - by Paul Smith
    Is it possible to create a Silverlight application which can be used to provide a nice user interface for managing SQL Server permissions? We want to create a simple admin app to allow certain users to create new users, disable old users, and manage specific permissions for those users, but we feel that SQL Server Management Studio is perhaps too complex.

  • Public code repository

    - by Andy White
    Can anyone recommend a public code repository? A few friends and I are thinking of starting a few projects for iPhone, web, Android, etc., and it would be nice to have a public (internet) code repository to use that would work well on any platform (Mac, PC, Linux). Any type of repository is fine (SVN, CVS, Git, etc.). A few ideas are Sourceforge or Google Code. Any recommendations? Thanks

  • Forcing deallocation of large cache object in Java

    - by Jack
    I use a large (millions) entries hashmap to cache values needed by an algorithm, the key is a combination of two objects as a long. Since it grows continuously (because keys in the map changes, so old ones are not needed anymore) it would be nice to be able to force wiping all the data contained in it and start again during the execution, is there a way to do effectively in Java? I mean release the associated memory (about 1-1.5gb of hashmap) and restart from the empty hashmap..

  • Is there a good date/time API available for Scala?

    - by Erik Engbrecht
    I'm looking for something akin to JodaTime or JSR 310 for Scala that leverages nice Scala features such as operator overloading and doesn't rely on implicit conversions (I have an irrational fear of implicit conversions). I'm aware of http://github.com/jorgeortiz85/scala-time, but it just pimps JodaTime with implicits.

  • ActiveRecord WHERE NOT EXISTS

    - by jspooner
    Is there a way to use EXISTS with ActiveRecord besides find_by_sql? I'd like a nice way to find all records without an association in a One-to-Many relationship. SELECT DISTINCT store_type FROM stores WHERE NOT EXISTS (SELECT * FROM cities_stores WHERE cities_stores.store_type = stores.store_type)

  • What's the best UML diagramming tool?

    - by eplawless
    I'm trying to choose a tool for creating UML diagrams of all flavours. Usability is a major criteria for me, but I'd still take more power with a steeper learning curve and be happy. Free (as in beer) would be nice, but I'd be willing to pay if the tool's worth it. What should I be using?

  • Any C/C++ to non-native bytecode compiler/interpreters?

    - by Matt
    As the title indicates, are there any C/C++ bytecode compilers/interpreters? I'm writing an application in an interpreted language that depends on certain libraries that are fully cross-compilable (there are no special flags to indicate code changes during compilation for a certain platform) but are written in C and C++. Rather than shipping n-platform-specific-libs with each platform, it would be nice to ship one set of libs which are interpreted by one platform specific interpreter. Possible and/or available?

  • Why aren't arrays expandable?

    - by Mustafa
    When we create an array, we cannot change its size; it's fixed. OK, seems nice, we can create a new bigger array and copy the values one by one and that's little slow. What's the technical background of it?
