• Tidbits of goodness - Podcasts, REST, JSON

  - by jeff.x.davies

  I've been quiet for a while, busy with a variety of projects. I did want to let you all know about a couple of things going on. First, I have been participating in architectural podcasts with Bob Rhubart. If you are interested in hearing these short (about 10 minutes each) recordings where a group of us discuss enterprise architecture and its future, check out http://blogs.oracle.com/archbeat/2010/05/podcast_show_notes_evolving_en.html Next, I have been working on the public sample code for the Oracle Service Bus 11g release. I'm now expanding my samples to include SCA, BPEL and the Oracle Adapters. This is really great experience for me because I have been learning these other tools to a deeper level and this provides insight into developing better solutions. You know the old saying, "If the only tool you have is a hammer, you tend to appraoch every problem as if it were a nail." However, I'm not the only one working on these samples. We have alot of our best and brightest working on sample code for the 11g release. Take a look at https://soasamples.samplecode.oracle.com/ to see all of the samples for SOA Suite 11g A reader wrote to me and asked me about using OSB to return information in JSON format. I don't have a sample posted for this yet, but I am working on getting one packaged up. In the mean time I can tell you that it is dead simple to do in OSB. Use the instructions I gave in an earlier blog entry on creating REST services using OSB, specify Messaging Service as the service type that takes a Text message and returns a Text message. Then have the OSB proxy service return a JSON formatted string (by replacing the contents of the $body variable with the JSON text) and you're done! This approach allows you to use OSB services from within Javascript/AJAX seamlessly. As I get more samples posted to the OTN site, I'll let you know. I have lots of interesting stuff on the way.

• Can't pass a single parameter to lambda function in MVVM Light Toolkit's RelayCommand

  - by Dave

  I don't know if there's a difference between Josh Smith's and Laurent Bugnion's implementations of RelayCommand or not, but everywhere I've looked, it sounds like the Execute portion of RelayCommand can take 0 or 1 parameters. I've only been able to get it to work with 0. When I try something like: public class Test { public RelayCommand MyCommand { get; set; } public Test() { MyCommand = new RelayCommand((param) => SomeFunc(param)); } private void SomeFunc( object param) { } } I get the error: Delegate 'System.Action' does not take '1' arguments. Just to make sure I am not insane, I went to the definition of RelayCommand to make sure I didn't have some rogue implementation in my solution somewhere, but sure enough, it was just Action, and not Action<. What on earth am I missing here?

• reuse proxy call data for extjs store

  - by user124118

  I have a xml that i need to bind to XTemplate. The XML structure is as follows John Smith John Doe Johny Byrd I am using Ext.data.Store with proxyurl tot he xml, Ext.data.XML reader to rad the xml and a listener that bind the data to the Xtemplate. The xmlreader needs a root node to be specified and i have to give root name as "Student_Name" It need to bind it to one more store for "Faculty_Name" as the root node. SO i end up calling my service to get xml twice. Is there a way to call service once to get the xml and bind it to two stores with different root nodes.

• In the Aggregate: How Will We Maintain Legacy Systems?

  - by Jim G.

  NEW YORK - With a blast that made skyscrapers tremble, an 83-year-old steam pipe sent a powerful message that the miles of tubes, wires and iron beneath New York and other U.S. cities are getting older and could become dangerously unstable. July 2007 Story About a Burst Steam Pipe in Manhattan We've heard about software rot and technical debt. And we've heard from the likes of: "Uncle Bob" Martin - Who warned us about "the consequences of making a mess". Michael C. Feathers - Who gave us guidance for 'Working Effectively With Legacy Code'. So certainly the software engineering community is aware of these issues. But I feel like our aggregate society does not appreciate how these issues can plague working systems and applications. As Steve McConnell notes: ...Unlike financial debt, technical debt is much less visible, and so people have an easier time ignoring it. If this is true, and I believe that it is, then I fear that governments and businesses may defer regular maintenance and fortification against hackers until it is too late. [Much like NYC and the steam pipes.] My Question: Do you share my concern? And if so, is there a way that we can avoid the software equivalent of NYC and the steam pipes?

• SQL Server: how to optimize "like" queries?

  - by duke84

  I have a query that searches for clients using "like" with wildcard. For example: SELECT TOP (10) [t0].[CLIENTNUMBER], [t0].[FIRSTNAME], [t0].[LASTNAME], [t0].[MI], [t0].[MDOCNUMBER] FROM [dbo].[CLIENT] AS [t0] WHERE (LTRIM(RTRIM([t0].[DOCREVNO])) = '0') AND ([t0].[FIRSTNAME] LIKE '%John%') AND ([t0].[LASTNAME] LIKE '%Smith%') AND ([t0].[SSN] LIKE '%123%') AND ([t0].[CLIENTNUMBER] LIKE '%123%') AND ([t0].[MDOCNUMBER] LIKE '%123%') AND ([t0].[CLIENTINDICATOR] = 'ON') It can also use less parameters in "where" clause, for example: SELECT TOP (10) [t0].[CLIENTNUMBER], [t0].[FIRSTNAME], [t0].[LASTNAME], [t0].[MI], [t0].[MDOCNUMBER] FROM [dbo].[CLIENT] AS [t0] WHERE (LTRIM(RTRIM([t0].[DOCREVNO])) = '0') AND ([t0].[FIRSTNAME] LIKE '%John%') AND ([t0].[CLIENTINDICATOR] = 'ON') Can anybody tell what is the best way to optimize performance of such query? Maybe I need to create an index? This table can have up to 1000K records in production.

• How can dev teams prevent slow performance in consumer apps?

  - by Crashworks

  When I previously asked what's responsible for slow software, a few answers I've received suggested it was a social and management problem: This isn't a technical problem, it's a marketing and management problem.... Utimately, the product mangers are responsible to write the specs for what the user is supposed to get. Lots of things can go wrong: The product manager fails to put button response in the spec ... The QA folks do a mediocre job of testing against the spec ... if the product management and QA staff are all asleep at the wheel, we programmers can't make up for that. —Bob Murphy People work on good-size apps. As they work, performance problems creep in, just like bugs. The difference is - bugs are "bad" - they cry out "find me, and fix me". Performance problems just sit there and get worse. Programmers often think "Well, my code wouldn't have a performance problem. Rather, management needs to buy me a newer/bigger/faster machine." The fact is, if developers periodically just hunt for performance problems (which is actually very easy) they could simply clean them out. —Mike Dunlavey So, if this is a social problem, what social mechanisms can an organization put into place to avoid shipping slow software to its customers?

• Staying OO and Testable while working with a database

  - by Adam Backstrom

  What are some OOP strategies for working with a database but keeping thing testable? Say I have a User class and my production environment works against MySQL. I see a couple possible approaches, shown here using PHP: Pass in a $data_source with interfaces for load() and save(), to abstract the backend source of data. When testing, pass a different data store. $user = new User( $mysql_data_source ); $user-load( 'bob' ); $user-setNickname( 'Robby' ); $user-save(); Use a factory that accesses the database and passes the result row to User's constructor. When testing, manually generate the $row parameter, or mock the object in UserFactory::$data_source. (How might I save changes to the record?) class UserFactory { static $data_source; public static function fetch( $username ) { $row = self::$data_source->get( [params] ); $user = new User( $row ); return $user; } } I have Design Patterns and Clean Code here next to me, but I'm struggling to find applicable concepts.

• At what point would you drop some of your principles of software development for the sake of more money?

  - by MeshMan

  I'd like to throw this question out there to interestingly see where the medium is. I'm going to admit that in my last 12 months, I picked up TDD and a lot of the Agile values in software development. I was so overwhelmed with how much better my development of software became that I would never drop them out of principle. Until...I was offered a contracting role that doubled my take home pay for the year. The company I joined didn't follow any specific methodology, the team hadn't heard of anything like code smells, SOLID, etc., and I certainly wasn't going to get away with spending time doing TDD if the team had never even seen unit testing in practice. Am I a sell out? No, not completely... Code will always been written "cleanly" (as per Uncle Bob's teachings) and the principles of SOLID will always be applied to the code that I write as they are needed. Testing was dropped for me though, the company couldn't afford to have such a unknown handed to the team who quite frankly, even I did create test frameworks, they would never use/maintain the test framework correctly. Using that as an example, what point would you say a developer should never drop his craftsmanship principles for the sake of money/other benefits to them personally? I understand that this can be a very personal opinion on how concerned one is to their own needs, business needs, and the sake of craftsmanship etc. But one can consider that for example testing can be dropped if the company decided they would rather have a test team, than rather understand unit testing in programming, would that be something you could forgive yourself for like I did? So given that there is something you would drop, there usually should be an equal cost in the business that makes up for what you drop - hopefully, unless of course you are pretty much out for lining your own pockets and not community/social collaborating ;). Double your money, go back to RAD? Or walk on, and look for someone doing Agile, and never look back...

• DVDs and CDs not recognized

  - by Larry Doyle

  I have Ubuntu 12.04 LTS installed on my computer (Sony Vaio VGN-NS205N). It reads some CDs and DVDs just fine, but many others it will not recognize at all, or will only recognize after opening and closing the CD tray many times. It just shows the cd/dvd drive as being empty and won't show that anything is on there at all. I have a few DVDs (from the same publisher) that work every time. This comes up most often when trying to show my kid Bob the Builder, etc. Some data CDs I would like to work with also have the same issue. It's not a hardware or defective disc problem, since all these will play in Windows on the same machine. It's just really annoying to have to switch operating systems to play videos or get data off discs. All the searches I have done people recommend installing medibuntu and other repositories. I have and they are all up to date. No change. Any help that works would be greatly appreciated.

• How to import text file to table with primary key as auto-increment

  - by webworm

  I have some bulk data in a text file that I need to import into a MySQL table. The table consists of two fields .. ID (integer with auto-increment) Name (varchar) The text file is a large collection of names with one name per line ... (example) John Doe Alex Smith Bob Denver I know how to import a text file via phpMyAdmin however, as far as I understand, I need to import data that has the same number of fields as the target table. Is there a way to import the data from my text file into one field and have the ID field auto-increment automatically? Thank you in advance for any help.

• How Can I Add a New Command to a Control's Event

  - by Chris

  Hi, thanks for taking a look at this question. I have been building an application (VB/WPF) following Josh Smith's example of an MVVM pattern: Click here to view My Views have Controls which trigger a Command upon an event, such as a button click and these are bound to properties in the ViewModel. My ViewModel exposes properties of type ICommand which invoke the appropriate methods. This has worked well, until now! I now want to use a Thumb Control to allow a user to move an object within a Canvas. I don't believe that the Thumb has a Command capability 'out of the box'. A Thumb raises a 'DragDelta' event when being moved. So my question is as follows: How do I extend a Control's capability to issue a Command upon an event please? I wish to issue a new Command, let's say 'onDragDelta' so that I can bind it to a property in my ViewModel just like my Buttons. Thank you very much

• How to define type-specific scripts when using a 'type object' programming pattern?

  - by Erik

  I am in the process of creating a game engine written in C++, using the C/C++ SQLite interface to achieve a 'type object' pattern. The process is largely similar to what is outlined here (Thank you Bob Nystrom for the great resource!). I have a generally defined Entity class that when a new object is created, data is taken from a SQLite database and then is pushed back into a pointer vector, which is then iterated through, calling update() for each object. All the ints, floats, strings are loaded in fine, but the script() member of Entity is proving an issue. It's not much fun having a bunch of stationary objects laying around my gameworld. The only solutions I've come up with so far are: Create a monolithic EntityScript class with member functions encompassing all game AI and then calling the corresponding script when iterating through the Entity vector. (Not ideal) Create bindings between C++ and a scripting language. This would seem to get the job done, but it feels like implementing this (given the potential memory overhead) and learning a new language is overkill for a small team (2-3 people) that know the entirety of the existing game engine. Can you suggest any possible alternatives? My ideal situation would be that to add content to the game, one would simply add a script file to the appropriate directory and append the SQLite database with all the object data. All that is required is to have a variety of integers and floats passed between both the engine and the script file.

• Best practices for using namespaces in C++.

  - by Dima

  I have read Uncle Bob's Clean Code a few months ago, and it has had a profound impact on the way I write code. Even if it seemed like he was repeating things that every programmer should know, putting them all together and putting them into practice does result in much cleaner code. In particular, I found breaking up large functions into many tiny functions, and breaking up large classes into many tiny classes to be incredibly useful. Now for the question. The book's examples are all in Java, while I have been working in C++ for the past several years. How would the ideas in Clean Code extend to the use of namespaces, which do not exist in Java? (Yes, I know about the Java packages, but it is not really the same.) Does it make sense to apply the idea of creating many tiny entities, each with a clearly define responsibility, to namespaces? Should a small group of related classes always be wrapped in a namespace? Is this the way to manage the complexity of having lots of tiny classes, or would the cost of managing lots of namespaces be prohibitive?

• What is the accepted pattern for WPF commanding in MVVM?

  - by Robert S.

  I'm working on a WPF app and I understand the command pattern pretty well, but I've found that there are several different implementations of the command pattern for MVVM. There's Josh Smith's implementation in his WPF sample app, the DelegateCommand from Prism, and the CommandBindings implementation. My question is, what is the generally accepted best practice for using commands with MVVM? My application uses Prism so DelegateCommand is available to us. The devs on my team are arguing about which approach is "best." Some don't like the numerous .cs files generated for each command, others prefer that everything be wired up via CommandBindings. I'm at a loss. Can anyone shed some light?
