  • How much does it cost to develop an iphone application?

    - by delooks
    How much can a developer charge for an iphone app like twitterrific. I want to know this because I need such an app with the same functionality for a new community website. I can do Ruby but have no experience with Objective C. So it would be interesting for me if I should start reading books about iPhone programming or outsource the work to a iPhone programmer.

  • Table in DB for generating primary keys?

    - by Sapphire
    Do you ever use a separate table for "generating" artificial primary keys for DB (and why)? What I mean is to have a table with two columns, table name and current ID - with which you could get new "ID" for some table by simply locking the row with that table name, getting the current value of the key, increment it by one, and unlock the row. Why would you prefer this over standard integer identity column? P.S. The "idea" is from Fowlers Patterns of Enterprise Application Architecture, btw...

  • Vim navigation clunkiness

    - by Sean Chambers
    I've committed myself to diving into vim to become faster at writing code for ruby/python and I'm having a hard time navigating around files. Mainly, I'm referring to switching between insert mode and navigation modes. Maybe I'm just not completely used to the editor yet but it feels very awkward to constantly be switching in and out of insert mode. Is this something that will go away with time? Are there any tricks to getting quicker at moving in and out of insert mode?

  • OpenSource programming-languages in development?

    - by pile of junk
    I'm very interested in interpreter and compiler development and because I don't want to continue building mini compilers and interpreters I thought I could help some open-source project. Are there currently open-source projects on compilers/interpreters in early stages seeking developers? I mean yeah.. There won't be much to do for someone like me in Python, Ruby, and so on.

  • Object Oriented vs Relational Databases

    - by Dan
    Objects oriented databases seem like a really cool idea to me, no need to worry about mapping your domain model to your database model, no messing around with sql or ORM tools. The way I understand it, relational DBs offer some advantages when there is massive amounts of data, and searching an indexing need to be done. To my mind 99% of websites are not massive, and enterprise issues never need to be thought about, so why arn't OO DBs more widely used?

  • Are There Any Other Web Programming Languages That Can Be Used Without A Framework Aside From PHP?

    - by Ygam
    Python needs a framework, so does Java (for the web). I don't know much about Ruby or Coldfusion. But is there another language out there for the web that can stand alone as it is without a need for a framework or without strict adherence to a design pattern (MVC and the likes) aside from PHP? BTW, the statement that Python and Java needs a framework to work with the web came purely from my readings on articles and books; I might be mistaken.

  • Script-Based Configuration in .net?

    - by Michael Stum
    One of the downsides of web.config/app.config is that it's just Magic Strings everywhere, since it's just an XML file. Interpreted languages like PHP or Ruby have the advantage that the configuration is just code that is executed. In .net, doing stuff in code requires a redeployment, which defeats the purpose. Now, before I build my own web.config replacement based on Boo or PowerShell I wanted to know if there is an existing one?

  • Using SQL Server for web applications

    - by rem
    As far as I understand, due to license reqirements all web applications, which use MS SQL Server, use SQL Server Express (free) or SQL Server web edition (processor license). Is it so? What are other specific features of SQL Server usage for web app?

  • Does anybody actually use the permissions policy controls in tomcat?

    - by stu
    While I can appreciate the point of the fine granularity in which you can enable security for every single little thing for each individual application in tomcat, in reality, it's an insane pain in the ass. Every single file, socket, everything for every single application. Sure if you're writing a "hello world" application, it's not too much to ask, but an enterprise sized application? That's insane. Does anybody actually use it, or does everybody just say "*" for everything?

  • What full featured (free) obfuscator do you all use?

    - by mike79
    I've just spent thousands of dollars on VSTS 2008 and thought that the usual Dotfuscaor Comunity Edition would've been upgraded to the pro version in this version of visual studio. After spending a fortune on Visual Studio Team Suite you would think you would get a full featured obfuscator for free. Now I have to spend another couple K for a PreEmptive Dotobfuscator license. What gives? What full featured (free) obfuscator do you all use?

  • Detecting a website's framework

    - by Rakesh Juyal
    I was reading the article "50 of the Best Websites Developed Using Ruby on Rails". It seems quite impressive. But is there any way to find out which framework any specific website uses? Say dzone.com, how could I find out which framework it is using? How could I find websites made with, for example, the Spring Framework?

  • Android Device Management

    - by Jon Hopkins
    I'm looking at the possibility of using Android as a secure corporate mobile platform. One of the pre-requisites for this will be a way of managing multiple devices, security policies, software deployment, that sort of thing - essentially the things the BlackBerry Enterprise Server handles for BlackBerry or MDM (or something 3rd party like SOTI) handles for Windows Mobile. Does such a thing exist for Android? It's a platform we're interested in but without this right now (and we're not in a position to build it ourselves) it's a non-starter.

  • Problem with URI matcher in Android.

    - by Lunchbox
    I have an authority string defined as such: public final static String AUTHORITY = "dsndata.sds2mobile.jobprovider"; Followed by an edition to the UriMatcher: uriMatcher.addURI(JobMetaData.AUTHORITY, "/JobNames/*", JOBNAME_SINGLE_URI); The uri that gets passed to the switch is: content://dsndata.sds2mobile.jobprovider/JobNames/test This falls through the switch and hits the default (which throws an IllegalArgumentException). Am I missing something? I've searched and can't find anything that would account for the mismatch.

  • Profiler tool for web service

    - by Rotem
    Hi, I need a profiler that is able to measure performance of web service execition. Our application has several layers and ideally I would like to be able to dive into each web service request and see how much time was spent in each layer (server, sql server, etc...) Is there a tool that can help detect where are the bottlenecks ? Is that something that can be done using VS Team System Test Edition ?

  • Parameterizing a SQL IN clause?

    - by Jeff Atwood
    How do I parameterize a query containing an IN clause with a variable number of arguments, like this one? select * from Tags where Name in ('ruby','rails','scruffy','rubyonrails') order by Count desc In this query, the number of arguments could be anywhere from 1 to 5. I would prefer not to use a dedicated stored procedure for this (or XML), but if there is some fancy SQL Server 2008 specific way of doing it elegantly, I am open to that.
