  • PostgreSQL compare databases tool or generating migration script util

    - by opedge
    In our development we use two servers with PostgreSQL 8.4 - development and production. So, after changes were made on development server we would like to automatically generate SQL migration scripts. I found that EMS DB Comparer for PostgreSQL can do it, but it is only for Windows (our development team use Ubuntu for developing). Do you now alternative tools to do this?

  • process tree

    - by Robert
    I'm looking for an easy way to find the process tree (as shown by tools like Process Explorer), in C# or other .Net language. It would also be useful to find the command-line arguments of another process (the StartInfo on System.Diagnostics.Process seems invalid for process other than the current process). I think these things can only be done by invoking the win32 api, but I'd be happy to be proved wrong. Thanks! Robert

  • Distributed Lucene.NET

    - by user72185
    Hi, I have a Terabyte of data, maybe more, which I'd like to index and search with Lucene. I'd like to be able to split the index out to different machines, similar to what Solr does (if I understand Solr correctly). Are there any existing tools to do this on the Windows platform? Thanks!

  • I would like to build a Java Web Application. What's the quickest start?

    - by Vish
    I am a reasonably competent programmer, with about 11 years experience. I particularly like Ruby/Rails and ActionScript. And Java is not too hard. I'd like to develop a web application in Java in order to leverage things like BlazeDS and learn some new tricks with regard to JBoss and the whole Java App thing. But I'm having trouble - and confused - looking for a smooth start. I don't want to use Grails, thanks, I want to use Pure Java, with whatever Framework you can think of. Spring, Hibernate, lalala, it's cool. Where do I start?

  • Adding comments to SVN revisions

    - by pako
    I'm using Subversion 1.6 and WebSVN. I'm looking for a simple tool, that would enable me to add custom comments to SVN revisions. So I would be able to see the stream of incoming revisions and mark which of them I already reviewed. An ability to share the comments with other programmers would also be a welcome addition, but it's not necessary. Could you recommend any tools for this?

  • ORA-01722: invalid number

    - by Lluis Martinez
    I'm getting the infamous invalid number Oracle error. Hibernate is issuing an INSERT with a lot of columns, I want to know just the name of the column giving the problem. Is it possible? I hate Oracle messages, in 15 years they haven't improved a bit (the reason why is beyond my imagination). FYI the insert is this: insert into GEM_INVOICE_HEADER (ENDORSEE_ACCOUNT_ID, INVOICE_CODE, APPROVAL_ORGAN, APROVAL_DATE, APROVAL_REFERENCE, BALANCE_BASE_AMOUNT, BALANCE_DEDUCT_AMOUNT, BALANCE_TOTAL_AMOUNT, BALANCE_VAT_AMOUNT, BALANCE_VAT_DED_AMOUNT, BALANCE_VAT_NOT_DED_AMOUNT, DESCRIPTION, SUPPLIER_INVOICE_NUMBER, INVOICE_DATE, RECEIPT_DATE, MEMO, VAT_INTRACOM, INVOICE_BASE_AMOUNT, INVOICE_VAT_AMOUNT, INVOICE_VAT_DED_AMOUNT, INVOICE_VAT_NOT_DED_AMOUNT, INVOICE_DEDUCT_AMOUNT, INVOICE_TOTAL_AMOUNT, VAT_EXEMPT, RECTIFICATION_SIGN, REASON, LOT, FILE_ID, RETAINED, INSTITUTION_ID, PERIOD_CODE, IS_RECTIFIED, DEFAULT_OFFBUDGET_ACCOUNT, OFFBUDGET_DOC_ID, PHASE_OF_ACCOUNTING, ACCOUNTED_OFF_BUDGET, CANCEL_DOC_ID, BUDGET_TYPE, INVOICE_TYPE, SOURCE_ID, STATE_ID, MANAGER_UNIT_ID, DOCUMENT_TYPE_CODE, ACCOUNTED_DOC_ID, ACCOUNTING_LIST, ENDORSEE_ID, PAYMASTER_ID, SUPPLIER_ID, SUPPLIER_ACCOUNT_ID, PAY_JUSTIFY_ID, PETTY_CASH_ID, DBOID) values (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)

  • Is there a production ready web application framework in Python?

    - by peperg
    I heard lots of good opinions about Python language. They say it's mature, expressive etc... Are there any production-ready web application frameworks in Python. By "production ready" I mean : supports objective-relational mapping with caching and declarative desciption (like JPA, Hibernate etc..) controls oriented user interface support - no HTML templates but something like JSF (RichFaces, Icefaces) or GWT, Vaadin, ZK component decomposition and dependency injection (like EJB or Spring) unit and integration testing good IDE support clustering, modularity etc (like Terracota, OSGi etc..) there are successful applications written in it by companies like IBM, Oracle etc (I mean real business applications not Twitter) could have commercial support Is it possible at all in Python world ? Or only choices are : use Python and write everything from the bottom (too expensice) stick to JEE buy .NET stack

  • Node.js or Erlang

    - by gotts
    I really like these tools when it comes to the concurrency level it can handle. Erlang looks like much more stable solution but requires much more learning and a lot of diving into functional language paradigm. And it looks like Erlang makes it much better when it comes to multi cores CPUs(fix me if I'm wrong). But which should I choose? Which one is better in the short/long term perspective?

  • Entity Framework: Data Centric vs. Object Centric

    - by Eric J.
    I'm having a look at Entity Framework and everything I'm reading takes a data centric approach to explaining EF. By that I mean that the fundamental relationships of the system are first defined in the database and objects are generated that reflect those relationships. Examples Quickstart (Entity Framework) Using Entity Framework entities as business objects? The EF documentation implies that it's not necessary to start from the database layer, e.g. Developers can work with a consistent application object model that can be mapped to various storage schemas When designing a new system (simplified version), I tend to first create a class model, then generate business objects from the model, code business layer stuff that can't be generated, and then worry about persistence (or rather work with a DBA and let him worry about the most efficient persistence strategy). That object centric approach is well supported by ORM technologies such as (n)Hibernate. Is there a reasonable path to an object centric approach with EF? Will I be swimming upstream going that route? Any good starting points?

  • Why does ANT tell me that JAVA_HOME is wrong when it is not?

    - by Ankur
    I get the error: C:\dev\ws\springapp\build.xml:81: Unable to find a javac compiler; com.sun.tools.javac.Main is not on the classpath. Perhaps JAVA_HOME does not point to the JDK. It is currently set to "C:\Program Files\Java\jre6" But I have clearly set my JAVA_HOME to be C:\Program Files\Java\jdk1.6.0_14 Where is ANT getting this value?
