  • DB Interface Design Optimization: Is it better to optimise for Fewer requests of smaller data size?

    - by Overflow
    The prevailing wisdom in webservices/web requests in general is to design your api such that you use as few requests as possible, and that each request returns therefore as much data as is needed In database design, the accepted wisdom is to design your queries to minimise size over the network, as opposed to minimizing the number of queries. They are both remote calls, so what gives?

  • apache httpclient and spawning a browser that will share the session

    - by Nick
    I'm have a java program that uses Apache httpclient api. This is used to login to and communicate to a webapp. Once logged in, there's a situation in which the program issues an execute process to open up firefox to hit the webapp and allow the user to see data in the browser. Since the java program is already logged in, is there a way to share that current session PHPSESSID so that the spawned firefox is already logged in and working in that same session?

  • Nhibernate, can i improve my MAPPING or Query

    - by dbones
    take this simple example A staff class which references other instances of the staff class public class Staff { public Staff() { Team = new List<Staff>(); } public virtual int Id { get; set; } public virtual string Name { get; set; } public virtual IList<Staff> Team { get; set; } public virtual Staff Manager { get; set; } } The Fluent Mapping public class StaffMap : ClassMap<Staff> { public StaffMap() { Id(x => x.Id); Map(x => x.Name); References(x => x.Manager).Column("ManagerId"); HasMany(x => x.Team).KeyColumn("ManagerId").Inverse(); } } Now I want to run a query, which will load all the Staff and eager load the manager and Team members. This is what I came up with IList<Staff> resutls = session.CreateCriteria<Staff>() .SetFetchMode("Team", FetchMode.Eager) .SetResultTransformer(Transformers.DistinctRootEntity) .List<Staff>(); however the SQL (does what i want) has duplicate columns, 2 team2_.ManagerId and 2 team2_.Id SELECT this_.Id as Id0_1_, this_.Name as Name0_1_, this_.ManagerId as ManagerId0_1_, team2_.ManagerId as ManagerId3_, team2_.Id as Id3_, team2_.Id as Id0_0_, team2_.Name as Name0_0_, team2_.ManagerId as ManagerId0_0_ FROM [SelfRef].[dbo].[Staff] this_ left outer join [SelfRef].[dbo].[Staff] team2_ on this_.Id=team2_.ManagerId The question is, should this be happening? did i do something wrong in the query or map? or is it a feature of the HHib im using (which is Version 2.1.0.4000)? many thanks in advance

  • Using ActiveRecord caching library in Heroku

    - by zetarun
    Hi all, I'm studying how to use caching in Heroku for my Rails app. HTTP cache powered by Varnish is superb and I'll use it in all pages without user info but I also want to use a kind of ActiveRecord caching with Memcached using "high livel" plugins such as cache_fu or cache-money...but it seems that Heroku supports only the memcached gem (http://docs.heroku.com/memcache) and it's a very low level Memcachad API... Do you have any other solutions? Thx.

  • Why do I get so many errors building my Android project with Ant?

    - by synic
    Now that I sort of know my way around the SDK/API, I've switched from Eclipse back to my favorite text editor, which means I have to use ant to build my project, however: It seems every other time I compile the project, a lot of drawables get corrupted, resources lose their ids (resulting in NPEs in the code), or classes throw "Verify Errors". The only way to fix this is by removing the bin and gen folders, and recompiling, which is obviously annoying. Is there any way to avoid this? btw, I'm using ant 1.7.1, java version "1.6.0_20"

  • Can two threads of the same process produce the same GUID?

    - by mark
    Dear ladies and sirs. If two threads in a process generate a new GUID concurrently using .NET API (Guid.NewGuid()) is it possible that the two GUIDs will be identical? Thanks. UPDATE I want to get practical. I know that it is widely assumed that GUIDs are unique for all practical purposes. I am wondering if I can treat GUIDS produced by the different threads of the same process in the same manner.

  • Application that depends heavily on stored procedures

    - by PieterG
    We currently have an application that depends largely on stored procedures. There is a heavy use of temp tables. It's an extremely large application. Facing this situation, I would like to use Entity Framework or Linq2Sql for a rewrite. I might consider using Fluent Hibernate or Subsonic, as i've used them quite extensively in the past. I've had problems with Linq2Sql generating the return types for the stored procedures because of the usage of the temp tables, and I think it's cumbersome to go and change all the stored procedures from temp tables to in-memory tables. Considering the 2 choices that I want to make, which one of the 2 is the best route to go and why? If my choices are extremely idiotic, please provide alternatives. Edit: The reason for the question and the change is that the data access layer is non-existent and was built 10 years ago. We currently still run into a lot of issues with it. I don't want to divulge too much, but if you saw it, your eyes would start bleeding :)

  • Deploying to Heroku with sensitive setting information

    - by TK
    I'm using GitHub for code and Heroku for the deployment platform for my rails app. I don't want to have sensitive data under Git. Such data include database file settings (database.yml) and some other files that have secret API keys. When I deploy to heroku, how can I deal with files that are not under revision control. When I use Capistrano, I can write some hook methods, but I don't know what to do with Heroku.
