• How do you deal with non-logical people in the workplace?

  - by unrealtrip

  I ask this because you are probably the best audience I could think of. I program for a living, and it goes hand in hand with my personality type which is likely true for most of us, as such I live and work in the world of logic and logical decisions. A problem I have is in dealing with people that live and work in a world of emotional responses and reactions that typically make no sense, or have any real bearing on any given situation. What is the trick to dealing with these people? It is nothing but an act of futility, leading to utter exasperation dealing with people like this when attempting to get them to understand some pretty basic concepts. How do you do it?

• AJAX Panel not throwing exceptions

  - by Grant

  Hi, i have just noticed something strange in some asp.net markup. I have a standard form with a couple of textboxes and a submit button. When clicked the code behind will attempt to perform some logic and then return. If the input values are not valid it used to throw an exception. The moment i wrapped the controls in an AJAX update panel and try to submit bad data, no exception is thrown and the panel returns like nothing was wrong. Does anyone know how to return this to the previous behavior whilst keeping the update panel?

• Updating external Flex components from an action

  - by Scott

  Hello, I'm new to Flex and am having trouble understanding Events. I think Events are what I want to use for my situation. I have 2 components, addUser.mxml and listUsers.mxml. I access these from a ViewStack in my main application. When I load listUsers.mxml it shows a list of current users in a datagrid via a HTTPService call. When I add a user using the form on addUser.mxml I would like the datagrid in listUsers.mxml to refresh when I return to that view to show the new user. I've tried several different things with addEventListener and dispatchEvent but can't seem to get it working. Can someone help me with this logic?

• I'm maintaining a java class that's 40K lines long.. problem?

  - by Billworth Vandory

  This may be a subjective question leading to deletion but I would really like some feedback. Recently, I moved to another very large enterprise project where I work as a C++ developer. I was aghast to find most classes in the project are anywhere from 8K to 50K lines long with methods that are 1K to 8K lines long. It's mostly business logic dealing with DB tables and data management, full of conditional statements to handle the use cases. Are classes this large common in large enterprise systems? I realize without looking at the code it's hard to make a determination, but have you ever worked on a system with classes this large?

• Refactoring FAT client legacy application

  - by Paul

  I am working on a fat client legacy C++ application which has a lot of business logic mixed in with the presentation side of things. I want to clean things out and refactor the code out completely, so there is a clear seperation of concerns. I am looking at MVC or some other suitable design pattern in order to achieve this. I would like to get recommendations from people who have walked this road before - Do I use MVP or MVC (or another pattern)? What is/are the best practices for undertaking something like this (i.e. useful steps/checks) ?

• Can I just release the top object (iPhone)?

  - by yar

  If I release the object that's holding a reference to the variable that I need to release, is that sufficient? Or must I release at every level of the containment hierarchy? I fear that my logic comes from working with a garbage collector for too long. For instance, I assigned to this property of a UIPickerView instance by hand instead of using IB @property(nonatomic, assign) id<UIPickerViewDelegate> delegate Since it's an assign property, I can't just release the reference after I assign it. When I finally release my UIPickerView instance, do I need to do this: [singlePicker.delegate release]; [singlePicker release]; or is the second line sufficient? Also: Are these assign properties the norm, or is that mostly for Interface Builder? I thought that retain properties were the normal thing to expect.

• Java synchronizing static list ?

  - by JavaUser

  Hi, In a Java class , i am having a static list so this list is shared across all the objects of this class.The business logic in this class will run periodically which is invoked by some method with out passing instance parameters.Now I want to invoke this run method based on the list(I will add some vales into this list based on JMS) ,this list may empty sometimes and after finishing the run , i am emptying this list.Now my question is , whether I need to synchronize this list or not? Also let me know is there any other way to pass value in one object instance(Thread1) to other object instance (Thread2) other than having Static variable(static list)? Thx

• How to invoke a Servlet (doGet) in a web application on startup?

  - by Dan

  I need to invoke a Servlet on application startup since it contains some application initialization logic. I know I can set load-on-startup configuration, but this will only invoke Servlet’s init method. I need to invoke a doGet method and pass some Url parameters to it. Servlet doGet method expects ServletRequest and ServletResponse objects. Also, since this is clustered application, I need to know exactly what node I am accessing (since one option is just to open a socket and invoke a Servlet). What is the best option to perform this?

• Dispatcher.CheckAccess() isn't working from my console application, is there a better way.

  - by zimmer62

  I wrote an application in WPF / VB and separated the business logic and UI into different projects. The business layer uses a serial port which runs on a different thread, Now that I'm trying to write a command line interface for the same business layer, it seems to fail when .Invoke() is called. (no error, just doesn't work) I'm pretty sure the reason I had to add in checkaccess and .invoke was because I have collections that would be changed during processing the serial port data and wanted the NotifyCollectionChanged to be handled by WPF data binding. (The reason I'm not 100% sure is because it was months ago I wrote that part and it all worked great from the GUI, now adding the console app has made me rethink some of this) I would like my business layer to run these processes on the thread they were created, I need this to work from both my GUI version and the command line version. Am I misusing the Dispatcher in my business layer? Is there a better way to handle an event from the serial port, and then return to the main thread to processes the data?

• PHP Framework Benefits / Downfalls

  - by Lizard

  I have been a PHP developer for about 10 years now and until about a month ago I have never used a framework. The framework I am now using due to an existing codebase is cakePHP 1.2 I can see certain benefits of the frameworks with the basic helpers like default layouts. I can definitely see the benefits of MVC keeping the logic separate etc. But the query building just seems to be bloated. Is this expected? Am I likely to be able to build better queries than the framework could build? I just feel I could get my apps running better without a framework. What are your thoughts?

• Display (tier) prices with qty increments and taxes

  - by witrin

  I need to display (tier) prices based on the qty increments of a product. E.g. a simple product, with a regular price of 50¢, no taxes and qty increments of 20 should be displayed on product views with "$10 per 20". Without using taxes this should be quite easy. But there seems to be no "default" helper or model to do this with taxes enabled and different calulation algorithms (e.g. Mage_Tax_Model_Calculation::CALC_UNIT_BASE); expect for quotes in Mage_Tax_Model_Sales_Total_Quote_Tax and Mage_Tax_Model_Sales_Total_Quote_Subtotal. Did I miss something here, or do I have to write the business logic on my own? And how I would best encapsulate it?

• "Teach" a computer how to do addition?

  - by ffar

  The problem is to learn computer to do addition. Computer have as input a knowladge of a numbers: he "knows" that after 1 goes 2, after 2 goes 3 and so on... Having that data computer can easyly get next number. Next, computer have knowlandge as input that x+0=x and x+(y+1)=(x+1)+y. This axioms let computer to do addition. For example, to add 5 and 3, computer makes following: 5+3 = 5+(2+1) = (5+1)+2 = 6+2 = 6+(1+1) = (6+1)+1 = 7+1 = 8. But this is too long to add numbers in such way. The problem is to develop program which can improve this way of addition using the rules of mathemetics and logic. The goal addition must executed in O(log(N)) time, not O(N) time, N is magnitude of added numbers. Have this program any science value? Is any program can do such things?

• C# - Silverlight - Custom control or UserControl ?

  - by cmaduro

  I need a button that is visually completely customizable, but has custom logic to publish events and manage it's visual state based on events it has registered for. When I say visually customizable, I mean I should be able to both create the button in xaml and set it's style by binding to the supplied style. Or I can create an instance of the button and set the style by passing a parameter to an alternate constructor. Or by calling a method on the button class to set the style. I do not plan on substituting the controls template, it should be a button. Can anyone point me to some code samples of this?

• How can I get my app ready for the iPhone 5

  - by RazorSharp

  Apple just announced the iPhone 5 with a 4 inch screen and a 16:9 aspect ratio. Of course, they only give developers two weeks to scramble to update their apps without being able to test. I'd like to update my app for the iPhone 5's new big screen, but there's nothing on Apple's developer site about the iPhone 5 or making your apps ready for a larger screen. It would be a pain to have to write my own logic for testing whether the device is an iPhone 5 and then displaying a custom storyboard file for it. Does anyone know how the new sizing works or if there are any hidden Xcode for this?

• Why don't paid for systems work properly? [closed]

  - by Kyle Sevenoaks

  Why when you buy a online store system that's advertised as Easy for you to manage and allows to change and tweak the look of store pages with unseen ease is it exactly the opposite? When you're offered six months free support do you never get an answer and finally when you make layout changes to one page, does a completely unrelated business logic completely break down? So really two questions: Why do authors of such systems put them up for sale before they're completed? How to exact revenge on said author? Thanks.

• Create xml file based on xPath from Excel with VBA

  - by user1626236

  I've found some items that seem to dance around what I'm looking to do. I'm not a full-fledged programmer, but have been creating my own macros in Excel. I'm trying to create one now that will help me create the structure of an XML file. I want to go down the list of XPaths, and for each one create any parents in the path as needed as well as the child and its value. I'll be adding another aspect to filter it to the fields I want, but the part I'm struggling with is the logic to check if each parent node exists, create it if needed, then add the child and its value. Bonus would be if the output file were formatted with each node on a new line, and more so if it child nodes were indented from parent, but just creating it is my primary concern. Any help would be much appreciated, this has to potential to save me a lot of time.

• Rails 2.3: using another models named_scope inside another named_scope

  - by mustafi

  Hi Let's say I have two models like so: class Comment < ActiveRecord::Base belongs_to :user named_scope :about_x :conditions => "comments.text like '%x%')" end class User < ActiveRecord::Base has_many :comments end How can I add a named_scope to the user model like so class User < ActiveRecord::Base has_many :comments named_scope :comments_about_x, :includes => :comments, :comments_named_scope => :about_x end Which allows me to do all_user_comments_about_x = User.comments_about_x The reasoning is I often need to use the comment models about_x named scope logic but I don't want to have "comments.text like '%x%')" scattered around my code. I hope this make sense :) Thank you

• Are hashCodes unique for Strings?

  - by Batty

  Recently, I came across a piece of code, where Map<Integer, String> is used, where Integer(key) is hashCode of some string and String value corresponding to that. Is this right thing to do? Because now, equals will not be called for the String when calling get. (get is also done using hashCode() method on String object. Or, hashCode(s) are unique for unique Strings? I checked equals od String class. There is logic written for that. I am confused.

• C# Improved algorithm

  - by generixs

  I have been asked at interview (C# 3.0) to provide a logic to remove a list of items from a list. I responded int[] items={1,2,3,4}; List<int> newList = new List<int>() { 1, 2, 3, 4, 5, 56, 788, 9 }; newList.RemoveAll((int i) => { return items.Contains(i); }); 1) The interviewer replied that the algorithm i had employed will gradually take time if the items grow and asked me to give even better and faster one.What would be the efficient algorithm ? 2) How can i achieve the same using LINQ? 3) He asked me to provide an example for Two-Way-Closure? (General I am aware of closure, what is Two-Way-Closure?, I replied there is no such term exists,but he did not satisfy).

• mySQL .NET API - Delete all data from table

  - by keynesiancross

  Hi all, I'm trying to figure out if there is an easy way to delete all the data in a table using the mySQL .NET API. The only slightly more tricky part to this is that in the C# code, the business logic can be run in both cases where there is, or isn't, data in teh table. So in some regards I almost need an If statement... Currently I am using the following code, but it doesn't seem to ever delete data... string deleteSQL = "DELETE FROM `data`.`currentData`"; MySqlCommand cmd2 = new MySqlCommand(deleteSQL, conn); Any thoughts would be much appreciated! Cheers

• @MustOverride annotation?

  - by Harrypotter2k5

  In .NET, one can specify a "mustoverride" attribute to a method in a particular superclass to ensure that subclasses override that particular method. I was wondering whether anybody has a custom java annotation that could achieve the same effect. Essentially what i want is to push for subclasses to override a method in a superclass that itself has some logic that must be run-through. I dont want to use abstract methods or interfaces, because i want some common functionality to be run in the super method, but more-or-less produce a compiler warning/error denoting that derivative classes should override a given method.

• PHP MySQL query string

  - by user1174762

  I am newer to PHP and MySQL and I am having trouble understanding join. I think, for me, the problem lies with actually understanding the logic of the query. What I am trying to do Is select all of the status updates from a table named "post", but only ones from users I am "following", and then display them In order by date. So, I have two databases which are set up like so: posts |post_id|user_id|post_body|date_upload| | 1 | 4 | hey. | 01/2/2012 | follows |relation_id|user_id|followee_id| | 1 | 4 | 2 | Could someone please explain how I should syntactically and Logically set this up? Thank you!
