• How to find thousands of company names?

  - by schefdev

  How can I find or generate thousands of company names for testing and demo purposes? (Address, phone number, and related information would be nice too.) I've got a system I'm building which includes business contact information. Pretty common no doubt. My test/demo database currently has randomly generated individual's names loaded (thanks to a handy IRS spreadsheet I found). This has worked great for internal testing and review purposes, but it looks really odd when shown to prospective customers. I've tried various online public information sources (e.g. EDGAR, and county based property records searches), but these all require me to manually stitch together the results in blocks of 50 names or so at a time. I could do this, but was really hoping for a search service or data store out there that had this type of information readily searchable and retrievable in very large batches.

• Can I program Nvidia's CUDA using only Python or do I have to learn C?

  - by Aquateenfan

  I guess the question speaks for itself. I'm interested in doing some serious computations but am not a programmer by trade. I can string enough python together to get done what I want. But can I write a program in python and have the GPU execute it using CUDA? Or do I have to use some mix of python and C? The examples on Klockner's (sp) "pyCUDA" webpage had a mix of both python and C, so I'm not sure what the answer is. If anyone wants to chime in about Opencl, feel free. I heard about this CUDA business only a couple of weeks ago and didn't know you could use your video cards like this. thx

• .NET assembly in GAC + Config

  - by Dante

  I have a .NET 3.5 assembly, a DAL, that connects to a database through Linq2SQL. I deploy this assembly in the GAC as it can be used by multiple business layers. The question is: in a dev environment I have a connection string different than the one in the production environment. Before deploying the assembly to the prod GAC I need to recompile it with the appropriate connection string. Is there any way to allow deploying the assembly to the GAC independently of the connection string, being that info read from some config? Thx in advance

• Full stack framework for Java

  - by Jonathan Barbero

  Hello everyone, I'm looking for a full stack framework (from persistency to view generation (CRUD)) for Java. I don't have experience with Rails style frameworks, like Grails, but I worked a lot with Hibernate, Struts, Spring ... I prefer a framework that let you naturally modify the business domain design with the less effort ( i.e. writing the sql querys to modify the tables and constrains, change the view pages, etc ... ). I was looking a bit about this topic, I saw Naked Objects for example but its development has stopped. So, I want to hear about your experience. Thanks in advance.

• Parsing HTML "Visually"

  - by Midhat

  OKay I am at loss how to name this question. I have some HTML files, probably written by lord Lucifier himself, that I need to parse. It consists of many segments like this, among other html tags <p>HeadingNumber</p> <p style="text-indent:number;margin-top:neg_num ">Heading Text</p> <p>Body</p> Notice that the heading number and text are in seperate p tags, aligned in a horizontal line by css. the css may be whatever Lucifier fancies, a mixture of indents, paddings, margins and positions. However that line is a single object in my business model and should be kept as such. So How do I detect whether two p elements are visually in a single line and process them accordingly. I believe the HTML files are well formed if it helps.

• Are self-described / auto-descriptive services loosely or tightly coupled in a SOA architecture ?

  - by snowflake

  I consider a self-described / auto-descriptive service as a good thing in a SOA architecture, since (almost) everything you know to call the service is present in the service contract (such a WSDL). Sample of a non self-described service for me is Facebook Query Language (FQL http://wiki.developers.facebook.com/index.php/FQL), or any web service exchanging XML flow in a one String parameter for then parsing XML and performing treatments. Last ones seem further more technically decoupled, since technically you can switch implementations without technical impact on the caller, handling compatibility between implementations/versions at a business level. On the other side, having no strong interface (diluted into the service and its version), make the service tightly coupled to the existing implementation (more difficulty to interchange the service and to ensure perfect compatibility). This question is related to http://stackoverflow.com/questions/2503071/how-to-implement-loose-coupling-with-a-soa-architecture So, are self-described / auto-descriptive services loosely or tightly coupled in a SOA architecture ? What are the impacts regarding ESBs ? Any pointer will be appreciated.

• In which layer should I join 2 entities together?

  - by William

  I use Spring MVC and a regular JDBC. I've just learned that I should separate business process into layers which are presentation layer, controller layer, service layer, and repository/DAO layer. Now suppose that I have an Entity called Person that can have multiple Jobs. Job itself is another entity which have its own properties. From what I gathered, the repository layer only manages one entity. Now I have one entity that contains another entity. Where do I "join" them? The service layer? Suppose I want to get a person whose job isn't known yet (lazy loading). But the system might ask what the job of that particular person is later on. What is the role of each layer in this case? Please let me know if I need to add any detail into this question.

• PL/SQL exception and Java programs

  - by edwards

  Hi Business logic is coded in pl/sql packages procedures and functions. Java programs call pl/sql packages procedures and functions to do database work. pl/sql programs store exceptions into Oracle tables whenever an exception is raised. How would my java programs get the exceptions since the exception instead of being propagated from pl/sql to java is getting persisted to a oracle table and the procs/functions just return 1 or 0. Sorry folks i should have added this constraint much earlier and avoided this confusion. As with many legacy projects we don't have the freedom to modify the stored procedures.

• How to make my Java Swing application a Client-Server application?

  - by Jonas

  I have made a Java Swing application. Now I would like to make it a Client-Server application. All clients should be notified when data on the server is changed, so I'm not looking for a Web Service. The Client-Server application will be run on a single LAN, it's a business application. The Server will contain a database, JavaDB. What technology and library is easiest to start with? Should I implement it from scratch using Sockets, or should I use Java RMI, or maybe JMS? Or are there other alternatives that are easier to start with? And is there any server library that I should use? Is Jetty an alternative?

• Playing around with my Java project in Eclipse... what the crap did I just do?

  - by Daddy Warbox

  I don't even remember how, but somehow I managed to make all of my project's source files hidden in Eclipse's Package and Project Explorer panels. Go figure. 'Show Filtered Children (alt+click)' temporarily reveals the files, and only in Package Explorer can I double-click to reopen them from this view. They go back into hiding after I select another item, though. Plus, now I'm getting other annoyances, such as all of the folded non-hidden items altogether expanding when I click on an item, and the entire folder tree of my project now being shown in these panels (including my .svn subversion folders... which shouldn't be any of Eclipse's business, presently). Long story short, my Package/Project Explorers' just blew up on me, and I want to know how to fix this. Thanks in advance. P.S. What's a good guide I can use to learn my way around this silly contraption, anyway?

• how do I return to the same exact page after posting a form?

  - by William Calleja

  I'm posting data to a page called process.aspx that handles some business logic with the following code: <%@ Page Language="C#" %> <% MyData.process(Request); Response.Redirect("") %> this page I will be calling from a variety of pages. Is there some way of knowing from which page my form was submitted? I was thinking something along the lines of writing: <form id="frmSystem" method="post" action="process.aspx?page=<%= %>"> However I don't know what to write in between the <%= %> to get the current page name. Can anyone help please?

• Dynamically adding Views in Silverlight & MVVM

  - by dvox

  Hi all, I am starting to re-write my whole silverlight business application in the MVVM pattern; My first stop-point is this: I have a page (View1) with corresponding ViewModel1 (with a property 'IEnumerable AllData'); Now, within this View, I want to have i.e. a tree-view control, in which one node will be populated with another View2; My question is: 1. How to do it? - I can't loop through the AllData property since it is asynchronously loaded... - thus I don't know the number of View2s' to insert - I don't know how to do it from ViewModel1 :( Will I need ViewModel2 with property 'MyDataEntity CurrentData'? or I can bind to AllData property from ViewModel1 Can you help me out? Thanks

• Using Drools to provide error processing and consequence management

  - by Mike

  Hi, I am working on a module whose purpose is to process Java exceptions and decide upon a strategy for dealing with them. The exceptions could be things I know about (explicit business exceptions eg TransformationException) or more general environmental stuff (JMS errors, IO errors etc) The facts inserted into the knowledge base are all the same class, and wrap (contain) an Exception. I want to write a rule that will explicitly match the exceptions I know how to deal with (eg TransformationException) and have another rule that catches 'everything else' The problem seems to me to be that for a fact containing a TransformationException, both rules will fire and the output will be uncertain. How would I go about writing such exclusive rules without relying on salience to steer the order of execution (this seems to be bad practice from what I have read)? I have a solution in place that I am not happy with whereby the outcome depends on the order in which the rules are defined in my .drl.

• Registering a piece of script across all the SharePoint Pages

  - by NLV

  Hello all I've a business requirement in which i need to create a SharePoint feature which registers a JavaScript across all the SharePoint pages. The only way i figured out to achieve it is that adding the script in (all) the SharePoint Master Pages or any other custom master pages present in the Site/Site Collection/Web Application while activating the feature. But i found that editing the master pages to add a Javascript snippet is not feasible. Finally i found that i could register my custom controls in the "Delegate Controls" and the custom user control i created can in turn register my script in the page. But my question is how can i handle it if the master page does not have a delegate control? Or is there any other possible solution to register a script across all the SharePoint pages?

• C# Reflection - How can I tell if object o is of type KeyValuePair and then cast it?

  - by Logan

  Hi All I'm currently trying to write a Dump() method from LinqPad equivalent iin C# for my own amusment. I'm moving from Java to C# and this is an exercise rather than a business requirement. I've got almost everything working except for Dumping a Dictionary. The problem is that KeyValuePair is a Value type. For most other Value types I simply call the ToString method but this is insufficient as the KeyValuePair may contain Enumerables and other objects with undesirable ToString methods. So I need to work out if it's a KeyValuePair and then cast it. In Java I could use wildcard generics for this but I don't know the equivalent in C#. Your quest, given an object o, determine if it's a KeyValuePair and call Print on its key and value. Print(object o) { ... } Thanks!

• Facebook API - Get comments

  - by Simon R

  Our business has a Facebook Fan Page. The fan page doesn't seem to generate any emails to us when updates are made to the page, whether someone adds a new status or someone comments on one of the statuses etc. Currently, we are running a very crude script to grab the content of the page and then use regular expressions to get the information we require. Obviously this is not fool proof and I'm looking into alternatives to this method. I've been looking at the facebook API and wonder if the rest server might be an option. I cannot, however, seem to find out how to return information of fan page statuses and their comments. Is anyone able to direct me how to use the API to retrieve this information. I am an admin of the fan page. The programming language I'm using is PHP. Many thanks.

• Free Tool(s) / Tips to assist me in filling out forms on Win7?

  - by MedicineMan

  I am doing some web development on some long forms. There are many fields for me to fill out to get through the form. Instead of typing out the same things every time (contact information, address, business information) I'm hoping there is some tool out there / combination of tools that will assist me in filling this out. Requirements: I am doing development / testing in FF, IE, and Chrome on a Win 7 system, so the tool would leverage one of those platforms. Oh yeah, one more thing: It's got to be free and lightweight, otherwise, I'd rather just type out responses to the form fields.

• Querying my JPA provider (Hibernate) for a collection of <Id,Name> of an entity

  - by Ittai

  Hi, I have an entity which looks something like this: Id (PK) Name Other business properties and associations... I have the need for my DAL (JPA with hibernate as provider) to return a list of the entities which correlate to some constraints (or just return them all) but instead of returning the entities themselves I'd like to receive only the Id and the Name properties. I know this can be achieved with HQL/SQL (something like: select id,name from entity where...) but I don't want to go down that road. I was thinking of somehow defining the pair a compositioned part of the entity and thought that might help me but I'm not sure that's "legal" as the Id is the PK. The logic for this scenario is to have a textbox which asynchronously queries the web-service (and through it the DAL) for the relevant entities and once an entity is selected then it is loaded as a whole and shipped to the front-end. Would appreciate any feedback, Ittai

• Any way to add an observer to the head of the queue using Element#observe?

  - by Josh

  This might not be possible but before I rewrite part of my application I wanted to ask... I have a JavaScript app which creates a submit <input> and observes that input's click event using Prototype's Element#observe function. For a few particular pages on one particular site which uses this app, I need to apply some additional business logic before the code which executes normally when the button is clicked. Is there any way I can use Elemen#observe to add my new event handler before the existing event handler, so I can stop the event if these new conditions aren't met? If not I'll probably solve this the "proper" way by having the application fire a specific beforeTakingAction event and add a listener for that which prevents the application from taking it's action, but that's more complicated than this simple problem requires, and requires rewriting part of a shared application for just one user...

• View / ViewModel - what is the sense (in a WPF control)?

  - by TomTom

  Not as funny as it sounds. Normally the View / ViewModel should decouple the presentation from the business logic. Good. Now, a Control in WPF is basically invisible unless made different (with the exceptions of UserControl and Window that have XAML directly attached). The Style is putting in the "visual presentation" - which basically means a Control does not need a view mechanism as WPF already has one? In addition. the ViewModel is actually part of the Control, or? Just fighting with that stuff. I know in ASP.NET, WinForms the separation makes a lot of sense - but there, basically, controls HAVE an intrinsic look. In WPF, I have some where it makes sense (derived from UserControl), but for the majority of the controls I write, the View & ViewModel look like pretty much totally superflous thanks to the already presenting view mechanism.

• Refactoring PL/SQL triggers - extract procedures

  - by Juraj

  Hello, we have application where database contains large parts of business logic in triggers, with a update subsequently firing triggers on several other tables. I want to refactor the mess and wanted to start by extracting procedures from triggers, but can't find any reliable tool to do this. Using "Extract procedure" in both SQL Developer and Toad failed to properly handle :new and :old trigger variables. If you had similar problem with triggers, did you find a way around it? EDIT: Ideally, only columns that are referenced by extracted code would be sent as in/out parameters, like: Example of original code to be extracted from trigger: ..... if :new.col1 = some_var then :new.col1 := :old.col1 end if ..... would become : procedure proc(in old_col1 varchar2, in out new_col1 varchar2, some_var varchar2) is begin if new_col1 = some_var then new_col1 := old_col1 end if; end; ...... proc(:old.col1,:new.col1, some_var);

• Using Subsonic 3.0 With Silverligh

  - by Craig

  I am writing a silverlight Line of business application and wanted to use the Subsonic DAL. The Silverlight Project will not allow me to Add the Subsonic reference with the followng error "You can not add the Subsonic.Core.Dll as it was not built against the Silverlight Runtime". I assume that I could create a webservice and add the Subsonic to that, but I would like to just add it to the Silverlight Project. Has anyone done this and if so how. If not is there an easy way to expose the DAL through the Webservice.
