• What would you like to see in a book about Rails 3?

  - by Ryan Bigg

  Hello, I'm thinking of writing a book about Rails 3 and I have a basic idea of what I want to write about, but really what I need is that little bit of polish from the community. The book is planned to cover: A little bit of Ruby Version control using Git Testing using RSpec & Cucumber Life without Rails (Rack) Developing an application in Rails (vague, I know, sorry! Work in progress) Javascript testing using Selenium Background processing Document databases (a tentative maybe, at this stage) Monitoring an application And a little more. So, I leave this question for you: What do you want to see in a book about Rails 3, which goes from "This is Rails" to "This is how Rails scales"?

• 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.

  - by srikanth rongali

• Codeigniter: simple form function

  - by Kevin Brown

  I'm stuck writing a simple form...I feel dumb. Here's my controller: function welcome_message(){ //Update welcome message $id = $this->session->userdata('id'); $profile['welcome_message'] = $this->input->post('welcome_message'); $this->db->update('be_user_profiles',$profile, array('user_id' => $id)); } And the html: <?php print form_open('home/welcome_message')?> <input type="checkbox" value="0" checked="false">Don't show me this again</input> <p> <input class="button submit" type="submit" class="close-box" value="Close" /> </p> <?php print form_close()?> Edit I simply need it to submit to a private function and return to the home page (page submitted from).

• Server-side access to Client Browser's Latitude/Longitude using Django.

  - by ZenGyro

  Hello, So i am writing a little app that compares a user's position against a database on web-based server written using Django and performs some functions with it. Accessing the browser's geolocation data (in supported browsers ) is fairly trivial using JavaScript. But what is the best way to allow the Django server to access the longitude and latitude variables? Is it best to wrap them up as a JSON object and send to the server via POST? Or is there some easier (Geo)Django-based way to access the Navigator.geolocation browser object. Please forgive a newbie a question like this, but my Google-Fuing only seems to find ways to insert variables into JavaScript via template tag, whereas I need it to work the other way! Any advice or code snippets greatly appreciated. Feel free to talk to me like I am an idiot.

• SubProject OR SubFolder ?

  - by user300435

  I am writing an asp.net application that exposes data in 2 ways: 1 - 1 common section that all users can see 2 - a Section that displays data specific to a registered user. in this case the user can decide how it looks (through themes), and manage the data to be displayed. Of course, the logic behind is the same, appearance would be different for as user1 and user2 The questions are : What would be best using : 'http://www.site.com/User1' or 'http://user1.site.com'. knowing that in both cases i have to make the displayed pages look like a seperate site then the root domain in anycase, the pages that will be displayed and customized on the fly are located in a subfolder of the of the asp.net project (projectrootpath\personalpages). What is the best way to map the personalpages subfolder to a subdomain or a 'http://www.site.com/userX' in the address bar. i also use "~/" in the urls which in this case needs to point to the personalpages rather then the root . Any help is gretaly apreciated.

• Rails test across multiple environments

  - by DSimon

  Is there some way to change Rails environments mid-way through a test? Or, alternately, what would be the right way to set up a test suite that can start up Rails in one environment, run the first half of my test in it, then restart Rails in another environment to finish the test? The two environments have separate databases. Some necessary context: I'm writing a Rails plugin that allows multiple installations of a Rails app to communicate with each other with user assistance, so that a user without Internet access can still use the app. They'll run a local version of an app, and upload their work to the online app by saving a file to a thumbdrive and taking it to an Internet cafe. The plugin adds two special environments to Rails: "offline-production" and "offline-test". I want to write functional tests that involve both the "test" and "offline-test" environments, to represent the main online version of the app and the local offline version of the app respectively.

• Mac: How to see list of running network services?

  - by Jordan

  I am writing an application that needs to connect with a running network service on a Mac. Problem is, I have no idea what the service is called or even what port it uses. Is there a way to browse all running network services on my Mac? More info: I am connecting to a MIDI network session (found under 'Audio MIDI settings', present on all OSX installs). Am I correct in thinking this is a network service? I am planning to use NSNetServiceBrowser to locate all local computers running this service. (is this the best way to go about it?) Any help is much appreciated - thanks!

• Unit Test this - Simple method but don't know what's to test!

  - by user309705

  a very simple method, but don't know what's to test! I'd like to test this method in Business Logic Layer, and the _dataAccess apparently is from data layer. public DataSet GetLinksByAnalysisId(int analysisId) { DataSet result = new DataSet(); result = _dataAccess.SelectAnalysisLinksOverviewByAnalysisId(analysisId); return result; } All Im testing really is to test _dataAccess.SelectAnalysisLinksOverviewByAnalysisId() is get called! here's my test code (using Rhino mock) [TestMethod] public void Test() { var _dataAccess = MockRepository.GenerateMock<IDataAccess>(); _dataAccess.Expect(x => x.SelectAnalysisLinksOverviewByAnalysisId(_settings.UserName, 0, out dateExecuted)); var analysisBusinessLogic = new AnalysisLinksBusinessLogic(_dataAccess); analysisBusinessLogic.GetLinksByAnalysisId(_settings, 0); _dataAccess.VerifyAllExpectations(); } Let me know if you writing the test for this method what would you test against? Many Thanks!

• Why it is necessary to put comments on check-ins? [closed]

  - by Mik Kardash

  In fact, I always have something to put in when I perform a check-in of my code. However, the question I have is - Is it really so necessary? Does it help so much? How? From one point of view, comments can help you to keep track of changes performed with every check-in. Thus, I will be able to analyze the changes and identify a hypothetic problem a little bit quicker. On the other hand, it takes some time to write useful information into check-in. Is it worth it? What are the pros and cons of writing comments to every check-in? Is there any way to write "efficient" check-in comments?

• Can you modify SQL DB schema in a transaction to know if all changes were applied?

  - by Chris F

  As part of my (new) database version control methodology, I'm writing a "change script" and want the change script to insert a new row into the SchemaChangeLog table if the script is executed successfully, or to reverse changes if any single change in the script fails. Is it possible to do schema changes in a transaction and only if it gets committed to then do the INSERT? For example (psuedo-code, I'm not too good with SQL): SET XACT_ABORT ON BEGIN TRANSACTION PRINT 'Add Col2 to Table1' IF NOT EXIST (SELECT * FROM sys.columns WHERE NAME='Col2' AND object_id=OBJECT_ID('Table1')) BEGIN ALTER TABLE [dbo].[Table1] ADD Col2 int NULL END -- maybe COMMIT here? INSERT INTO SchemaChangeLog VALUES(...) COMMIT TRANSACTION

• How do I run an XSLT file?

  - by Eric

  Alright this seems like a stupid question but I can't figure it out. I'm writing an XSLT file to translate an XML document into an XHTML document. I've used both Visual Studio and XML Notepad 2007 to preview the results of my XSLT file, but now I want to actually write out a real XHTML file so I can see how it looks in other browsers. Neither Visual Studio or XML NotePad have an obvious way to save the preview. Am I missing something. Obviously the file is getting created because something is being previewed, but I need to know where that file is being created or better yet choose its location.

• Extending fluent nhibernate mappings in another assembly

  - by Jarek

  Hi, I'm using NHibernate with my ASP.Net MVC application. I'm writing some extensions (plugins) for my application. And I'm loading those plugin dynamically (from different assemblies). In my base application I have many entities and mappings defined (User, Group, etc...) I need to create new entities in my extensions, so i.e. I'm creating News module, so I need to create News mapping. In database News table has a foreign key to User table. Is there any way I can modify my User mapping, so it will have: HasMany(x => x.Courses) .KeyColumn("GroupId") .Inverse(); Or the only way to do it is to change code in my User class and recompile project ? I'm not NHibernate advanced user, so any help will be appreciated. TIA.

• Best method of including an abstract in a latex 'book'?

  - by olan

  Hello there. I've been looking for the answer to this question for a while now but can't seem to find it, so I'm hoping someone on here can help me. I'm writing up a thesis in Latex, and really like the \frontmatter, \mainmatter and \backmatter ability when using the "book" environment. However I need to add an abstract and the \begin{abstract} environment is undefined when creating a "book". If I change to a "report" however, I lose the functionality of the *matter terms. So what I really need to know is: is there a simple method of including an abstract in a "book" and have it formatted the same as it would be in a "report"? (i.e. centered vertically and horizontally with an 'abstract' heading) Thanks for any help! First post on stackoverflow after reading for months!

• How do you find the last element of an array while iterating using a foreach loop in php ?

  - by Vaibhav Kamble

  I am writing a sql query creator using some parameters. While doing that ,I came across this problem. In java , Its very easy to detect the last element of an array from inside the for loop by just checking the current array position with the array length. for(int i=0; i< arr.length;i++){ boolean isLastElem = i== (arr.length -1) ? true : false; } php has some different fashion. They have non integer indexes to access arrays. So you must iterate over an array using foreach loop. But it becomes very problematic when you need to take some decision (in my case to append or/and parameter while building query). I am sure there must be some standard way of doing this. How do you solve this problem normally in php ?

• Command line tool (PDF Workflow) in OSX that detects if key is down

  - by kroko

  Hello! I'm writing a OSX PDF Workflow in ObjC and C. A single executable ("UNIX Tool" as named in the Apple reference), that reads in the spooled PDF file, does some parsing. I'd like to give more functionality by enabling a key-down event handling, meaning - when user opens print dialog in an application - and chooses to left-mouse-click on the custom made pdf workflow to run it - depending on if a keyboard key is down (i.e. option key, but "any key down" would be enough for me) when running that workflow - a decision is made in the code. I have read NSEvent and Carbon Event Manager reference and it seems that in this case (a plain unix executable + not run as root) it's not possible. Or is it? Many thanks in advance, Kroko

• Bash: Continue script if only one instance is running.

  - by Andrew

  Hello, now this is embarrassing. I'm writing quick script and I can't figure out why this statement don't work. if [ $(pidof -x test.sh | wc -w) -eq 1 ]; then echo Passed; fi I also tried using back-ticks instead of $() but it still wouldn't work. Can you see what is wrong with it? pidof -x test.sh | wc -w returns 1 if I run it inside of script, so I don't see any reason why basically if [ 1 -eq 1 ] wouldn't pass. Thanks a lot!

• Problem overridding virtual function

  - by William

  Okay, I'm writing a game that has a vector of a pairent class (enemy) that s going to be filled with children classes (goomba, koopa, boss1) and I need to make it so when I call update it calls the childclasses respective update. I have managed to create a example of my problem. #include <stdio.h> class A{ public: virtual void print(){printf("Hello from A");} }; class B : public A{ public: void print(){printf("Hello from B");} }; int main(){ A ab = B(); ab.print(); while(true){} } Output wanted: "Hello from B" Output got: "Hello from A" How do I get it to call B's print function?

• Can a MAC address be used as a reliable part of a rights management (DRM) scheme?

  - by Jarrod Mosen

  We're currently writing some software that we want to protect. We thought that registering a user's MAC address in a database upon activation of the software seemed viable; we can profile and grab that with a Java applet, (is there a better way?) so getting it isn't too much of a problem. However, we want their computer to only run the application, and download application files/updates from the server when their MAC address has been verified with their one on-file. We understand that this means a lockdown to one computer, but special changes can be made on request. What would be the best way to verify their MAC address, to see if it exists in the database, and then serve them the files to run the application? (And to simply run it on subsequent requests, to prevent re-downloading.)

• Would you hire a foreigner ? [closed]

  - by user229999

  Hi! I'd like to dedicate this question (hope it's not a subjective) especially to people who own their companies. Would you (and why) hire a foreigner, which experience is documented in CV and portfolio, which can communicate in english (with grammar mistakes, but still)? I am writing in the name of all these guys looking for great opportunities abroad, living in countries which do not give you any opportunities at all. Is it real, to be hired like a programmer (PHP, Ruby, Python, C#) in country like UK, USA, Nederland, Sweeden or even Germany, if you're a foreigner? Please response in two categories: a) foreigner with engineer degree, zend certificate, few open source projects b) foreigner without any degree, with nice portfolio, and few big projects created Also, does First Certificate in English aka FCE matter for you ?

• Does JavaScript have an equivalent to Perl's DESTROY method?

  - by Eric Strom

  Is there any method that is called or event that is dispatched right before an Element is cleaned up by the JavaScript garbage collector? In Perl I would write: package MyObj; sub new {bless {}} sub DESTROY {print "cleaning up @_\n"} and then later: { my $obj = MyObj->new; # do something with obj } # scope ends, and assuming there are no external references to $obj, # the DESTROY method will be called before the object's memory is freed My target platform is Firefox (and I have no need to support other browsers), so if there is only a Firefox specific way of doing this, that is fine. And a little background: I am writing the Perl module XUL::Gui which serves as a bridge between Perl and Firefox, and I am currently working on plugging a few memory leaks related to DOM Elements sticking around forever, even after they are gone and no more references remain on the Perl side. So I am looking for ways to either figure out when JavaScript Elements will be destroyed, or a way to force JavaScript to cleanup an object.

• .net Compiler Optimizations

  - by Dested

  I am writing an application that I need to run at incredibly low speeds. The application creates and destroys memory in creative ways throughout its run, and it works just fine. I am wondering what compiler optimizations occur so I can try to build to that. One trick off hand is that the CLR handles arrays much faster than lists, so if you need to handle a ton of elements in a List, you may be better off calling ToArray() and handling it rather than calling ElementAt() again and again. I am wondering if there is any sort of comprehensive list for this kind of thing, or maybe the SO community can create one :-)

• How to make 2 executables communicate in both directions in Windows

  - by user302099

  Hello. I have 2 Windows console applications, reading from standard input and writing to standard output. I'd like to assume I don't have the source code to any of them (actually I usually have the source code of one of them). I want to direct the standard output of one to the standard input of the other and vice versa, thus allowing communication (the goal is to allow two programs playing a certain game to play one against the other). How can this be done? I'm willing to do some C/C++ programming or anything else required. Oren.

• MySQL : select/join on strings as fieldnames - is this possible?

  - by Dylan

  I can retrieve all column names from table 'categories' with : SELECT col.column_name FROM information_schema.columns AS col WHERE col.table_schema= database() and col.table_name = "categories" This produces a resultset like this : column_name ----------------- categoryID name description I can retrieve all values for a specific category with : SELECT * FROM categories AS c WHERE c.categoryID=12345 this results in a resultset like this: categoryID | name | description ------------------------------------------------ 12345 | test | this is a test Now I would like to get some kind of join of above selects to get a resultset that looks something like this : fieldname | value ---------------------------------------- categoryID | 12345 name | test description | this is a test Does anyone know if this is possible ? Can you do a join on strings that come from another select ?? The reason for this is that I'm writing a universal stored procedure that outputs all fields + their values from a table, without knowing what fields there are in the table. (The tablename is given in a parameter)
