• Rosetta Stone: Observer Pattern

  - by Shiftbit

  How is the Observer Pattern expressed in various programming languages? Can you provide a code snippet that illustrates the major differences in each language. This post is intended to demonstrate the differences of this commonly used design pattern. I will start this off with a Java example. Remember to start your answer off with the language being demonstrated.

• Improving as a coder with respect to design.

  - by dmarakaki

  As a soon-to-be computer science graduate, I have to come realization that I have a long way to go when it comes to the overall design of an application. After spending many semesters of programming from the hip I have come to appreciate the mulling over the needs of an application before diving head first into the coding portion. My question is to the intermediate and expert programmers, how can I improve in the area of the design phase of development?

• SVG -- Replacement for Flash application

  - by Vadi

  We are currently looking at developing flash based applications (using Flex) in a web application. We are now leaning towards to use SVG rapheljs for developing this components. The questions are: Is still SVG platform is widely adopted by browsers (without any plug-ins) are at least down the line of 8-10 months, any adoption is expected by browsers? Cross-browser support is god for us. Is SVG can replace for a small time animation based programming instead of Flash Any comments will be greatly appreciated...

• HTML5 web storage: can different websites overwrite each other’s data on a user’s computer?

  - by Deepak Mahalingam

  I have a few questions regarding the concept of HTML5 storage. I went through the w3c specification, books and tutorials on the same, but still I am a bit unclear about certain concepts: Assume that I access Website A. Some JavaScript runs in my browser that sets a key value pair, say ('username','deepak'). Then I access Website B which also adds a key,value pair in the localstorage as ('username','mahalingam'). How will they both be differentiated? Will Website B override the value set by website A in my localstorage? How can we ensure that a website would not erase all of my localstorage?

• Tips on a tool to measure code quality?

  - by Cristi Diaconescu

  I'm looking for a tool that can provide code quality metrics. For instance it could report very long functions (spaghetti code) very complex classes (which could contain do-it-all code) ... While we're on the (subjective:-) subject of code quality, what other code metrics would you suggest? I'm targetting C#/.NET code, but I'm sure this could extend to most programming languages.

• New Facebook FQL table vs. Grap API

  - by PanosJee

  Hello everyone I just read the new User fql table fields at http://developers.facebook.com/docs/reference/fql/user As I can see a lot of the fields have been deprecated such as work_history or books and movies. It is quite essential for my app to get all those fields for my user's friends in a single fql query. If i am not wrong the only way to do this is to get those extra fields using the Graph API by requesting them seperately for every friend of my user. Is there any way to do it in a more efficient way without so many calls? Can I subscribe to real time updates for the request fields for my user's friends (i do not care about the logged in user data)? Thank you a lot

• Is Flash/Actionscript any safer than Javascript for persistent online game?

  - by Sean Madigan

  I'm finding lately how unsecure Javascript is when programming a game (I'm trying to do a turn based RPG and currently the battle calculations are done through Javascript which any player can cheat with of course giving themselves as much XP as they want), so I'm wondering if I were to move my battle screen to flash if this would be any more secure, or is there just as easy of a way to cheat this?

• FullText Search using multiple tables in SQL

  - by Caesar

  Hi there. I have 3 tables, tblBook(BookID, ISBN, Title, Summary) tblAuthor(AuthorID, FullName) tblBookAuthor(BookAuthorID, BookID, AuthorID) tblBookAuthor allows for a single book to have multiple authors and an author may have written any number of books. I am using full text search to search for ranking base on a word: SET @Word = 'FORMSOF(INFLECTIONAL, "' + @Word + '")' SELECT COALESCE(ISBNResults.[KEY], TitleResults.[KEY], SummaryResults.[KEY]) AS [KEY], ISNULL(ISBNResults.Rank, 0) * 3 + ISNULL(TitleResults.Rank, 0) * 2 + ISNULL(SummaryResults.Rank, 0) AS Rank FROM CONTAINSTABLE(tblBook, ISBN, @Word, LANGUAGE 'English') AS ISBNResults FULL OUTER JOIN CONTAINSTABLE(tblBook, Title, @Word, LANGUAGE 'English') AS TitleResults ON ISBNResults.[KEY] = TitleResults.[KEY] FULL OUTER JOIN CONTAINSTABLE(tblBook, Summary, @Word, LANGUAGE 'English') AS SummaryResults ON ISBNResults.[KEY] = SummaryResults.[KEY] The above code works fine for just searching tblBook table. But now I would like to search also the table tblAuthor based on key word searched. Can you help me with this?

  When learning a new programming language, one of the possible roadblocks you might encounter is the question whether the language is, by default, pass-by-value or pass-by-reference So here is my question to all of you, in your favorite language, how is it actually done? and what are the possible pitfalls? your favorite language can, of course, be anything you have ever played with: popular, obscure, esoteric, new, old ...

• Is MVVM pointless?

  - by joebeazelman

  Is orthodox MVVM implementation pointless? I am creating a new application and I considered Windows Forms and WPF. I chose WPF because it's future-proof and offer lots of flexibility. There is less code and easier to make significant changes to your UI using XAML. Since the choice for WPF is obvious, I figured that I may as well go all the way by using MVVM as my application architecture since it offers blendability, separation concerns and unit testability. Theoretically, it seems beautiful like the holy grail of UI programming. This brief adventure; however, has turned into a real headache. As expected in practice, I’m finding that I’ve traded one problem for another. I tend to be an obsessive programmer in that I want to do things the right way so that I can get the right results and possibly become a better programmer. The MVVM pattern just flunked my test on productivity and has just turned into a big yucky hack! The clear case in point is adding support for a Modal dialog box. The correct way is to put up a dialog box and tie it to a view model. Getting this to work is difficult. In order to benefit from the MVVM pattern, you have to distribute code in several places throughout the layers of your application. You also have to use esoteric programming constructs like templates and lamba expressions. Stuff that makes you stare at the screen scratching your head. This makes maintenance and debugging a nightmare waiting to happen as I recently discovered. I had an about box working fine until I got an exception the second time I invoked it, saying that it couldn’t show the dialog box again once it is closed. I had to add an event handler for the close functionality to the dialog window, another one in the IDialogView implementation of it and finally another in the IDialogViewModel. I thought MVVM would save us from such extravagant hackery! There are several folks out there with competing solutions to this problem and they are all hacks and don’t provide a clean, easily reusable, elegant solution. Most of the MVVM toolkits gloss over dialogs and when they do address them, they are just alert boxes that don’t require custom interfaces or view models. I’m planning on giving up on the MVVM view pattern, at least its orthodox implementation of it. What do you think? Has it been worth the trouble for you if you had any? Am I just a incompetent programmer or does MVVM not what it's hyped up to be?

• Learning Linux screencasts

  - by Dmitriy Nagirnyak

  Hi, I am trying to get started with Linux. There are number of books (many of which are just man pages), some of them provide good overview so I can dig deeper online then. What I would like is to find number of screencasts that would cover basics of Linux commands, server administration, commonly performed tasks etc (no GUI, only terminal). I want to watch the screencasts to "get it quicker" and then use a book or online resources to "dig it deeper". Any recommendations? Thanks, Dmitriy.
