• Will performance of a SQL server degrade if the DB can't fit in the memory?

  - by Carl Hörberg

  Will the performance of a SQL server drastically degrade if the database is bigger than the RAM? Or does only the index have to fit in the memory? I know this is complex, but as a rule of thumb?

• ActiveMQ - sending message to specific consumer

  - by archer

  Hello. Having single AMQ broker and 100 consumers connected. I would send the message to some specific consumer, so other consumers does not receive it (client-side filtering won't work). Simplest way is to create virtual destinations (name them queue:consumer-) for example and send messages there. However this will lead to 100 new queues which makes it more complex to monitor. Is there any other way to do this having single queue?

• What's your "best practice" for the first Java EE Spring project?

Which technology did you use right away: AOP, complex Hibernate...

• Is MapReduce one form of Continuation-Passing Style (CPS)?

  - by Jeffrey

  As the title says. I was reading Yet Another Language Geek: Continuation-Passing Style and I was sort of wondering if MapReduce can be categorized as one form of Continuation-Passing Style aka CPS. I am also wondering how can CPS utilise more than one computer to perform complex computation. Maybe CPS makes it easier to work with Actor model.

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.

• Singleton Pattern for C#

  - by cam

  I need to store a bunch of variables that need to be accessed globally and I'm wondering if a singleton pattern would be applicable. From the examples I've seen, a singleton pattern is just a static class that can't be inherited. But the examples I've seen are overly complex for my needs. What would be the very simplest singleton class? Couldn't I just make a static, sealed class with some variables inside?

• Generating db schema from c# class

  - by Niran

  Hi, Is there any other method than nHibernate by wich we can generate db schema from class definition? My classes arn't that complex etc (few one-to-many relations). However I would like to just be able to save my objects in db and recreate schema if needed. I am stuck with .NET 2.0. I am not that particular about performance for this project, I am just lazy to create tables and write save/load code and deel with nHibernate xml. Thanks

• where from does paperclip get the name of original file?

  - by Pavel K.

  i started using nginx upload module (which creates upload files like /tmp/000121545) but i need paperclip to use original filename while saving files (like /public/avatars/LuckyLuke.jpg) previously in the parameters Rails were passing just "avatar"=>#<File:/tmp/RackMultipart20100413-6151-t3ecq0-0> no original filename as well, so i am wondering where from does it come in paperclip? i tried looking through plugin code but it's currently a bit too complex for me.

• Setting wildcard queries as default for QueryParser

  - by user46703

  When my users enter a term like "word" I would like it be treated as a wildcard query "word*" so all terms beginning "word" are found. Is there a way to tell the QueryParser to automatically create wildcard queries or do I have to parse the query myself? This shouldn't be a problem for simple queries but it may become tricky for more complex queries.

• is there a comprehensive example or tutorial for ibatis 3 with annotations?

  - by nn2010

  I am specifically interested in moving away from XML-based mapper configuration to using pure Java annotations where the SQL statements often take or return complex data structures. Also, it wasn't clear in the samples I saw, how the configuration file was adapted when moving away from XML-based mappers to annotation-based Mapper interfaces.

• How to express "where value is in dynamic list" in HQL/GORM?

  - by xcut

  For a grails application, I need to find a list of objects whose "attr" is one in a dynamic list of strings. The actual HQL query is more complex, but the bit I need help with is this: def result = MyObject.executeQuery("select o from MyObject as o where o.attr in :list", [list: aListOfStrings]) This is obviously not the right syntax, Grails throws it back at me as an "unexpected token", being the :list parameter. Is this possible in HQL? I don't particularly want to use Criteria in this part of the codebase.

• What are the limitations of assembler? (NASM)

  - by citronas

I know I wouldn't write such programs, but I'm curious, if there are technical limitations on what kind of programs I can write with assembler.

• Is there a way to do gsp partials rather than tag libraries?

  - by egervari

  One of the things I liked about freemarker is that you can quickly create new macros that encapsulate complex html to make the pages smaller and more concise. Do I have to make tag libraries to do the same thing in grails, or is there a really light-weight syntax for achieving the same thing?

So I bet I need some hacker-style tool? Some client? (i mean... why not just provide a zip? isn't the world complex enough?)
