• What are the benefits of PHP?

  - by acme

  Everybody knows that people that have prejudices against certain programming languages. Especially PHP seems to suffer from problems of its past and some other things (like loose types) and is often called a non-serious programming language that should not be used for professional applications. In that special case PHP: How do you argue using PHP as your chosen programming language for web applications? What are the benefits, where is PHP better than ColdFusion, Java, etc.?

The intent is to bring greater awareness to our user community of some fantastic best practices documents that are available to anyone with a valid CSI.   These documents were originally created for our internal teams, but the content was so good and useful that we have made them available externally for our user community.  The first in our series is the Oracle GoldenGate database Schema Profile check script (Doc ID 1296168.1). “This script is intended to query the database by schema to identify current configuration and identify any unsupported data types or types that may need special considerations for Oracle GoldenGate in an Oracle environment. This is the Oracle database profile script.  Added check for deferred constraints. Deferred constraints may cause ADD TRANDATA to select the wrong column for logging.

• Using NBuilder to mock up a data driven UI - Part 1

  In this article we will take a look at a fairly new open source project called NBuilder (http://www.nbuilder.org and http://code.google.com/p/nbuilder/) and how it can be used to provide us with fake data out of the gate. NBuilder allows you to quickly stand up generated objects based on standard .net types in an easy fluent manner. And that is just the start!

• How do you author code

  - by garbagecollector

  This is something I was never taught. I have seen alot of different types of authoring styles. I code primarily in Java and Python. I was wondering if there was a standard authoring style or if everything is freestyle. Also if you answer would you mind attaching the style you use to author files that your create at home or at work. I usually just go @author garbagecollector @company garbage inc.

• What are some reasonable stylistic limits on type inference?

  - by Jon Purdy

  C++0x adds pretty darn comprehensive type inference support. I'm sorely tempted to use it everywhere possible to avoid undue repetition, but I'm wondering if removing explicit type information all over the place is such a good idea. Consider this rather contrived example: Foo.h: #include <set> class Foo { private: static std::set<Foo*> instances; public: Foo(); ~Foo(); // What does it return? Who cares! Just forward it! static decltype(instances.begin()) begin() { return instances.begin(); } static decltype(instances.end()) end() { return instances.end(); } }; Foo.cpp: #include <Foo.h> #include <Bar.h> // The type need only be specified in one location! // But I do have to open the header to find out what it actually is. decltype(Foo::instances) Foo::instances; Foo() { // What is the type of x? auto x = Bar::get_something(); // What does do_something() return? auto y = x.do_something(*this); // Well, it's convertible to bool somehow... if (!y) throw "a constant, old school"; instances.insert(this); } ~Foo() { instances.erase(this); } Would you say this is reasonable, or is it completely ridiculous? After all, especially if you're used to developing in a dynamic language, you don't really need to care all that much about the types of things, and can trust that the compiler will catch any egregious abuses of the type system. But for those of you that rely on editor support for method signatures, you're out of luck, so using this style in a library interface is probably really bad practice. I find that writing things with all possible types implicit actually makes my code a lot easier for me to follow, because it removes nearly all of the usual clutter of C++. Your mileage may, of course, vary, and that's what I'm interested in hearing about. What are the specific advantages and disadvantages to radical use of type inference?

• Best Practices for serializing/persisting String Object Dictionary entities

  - by Mark Heath

  I'm noticing a trend towards using a dictionary of string to object (or sometimes string to string), instead of strongly typed objects. For example, the new Katana project makes heavy use of IDictionary<string,object>. This approach avoids the need to continually update your entity classes/DTOs and the database tables that persist them with new properties. It also avoids the need to create new derived entity types to support new types of entity, since the Dictionary is flexible enough to store any arbitrary properties. Here's a contrived example: class StorageDevice { public int Id { get; set; } public string Name { get; set; } } class NetworkShare : StorageDevice { public string Path { get; set; } public string LoginName { get; set; } public string Password { get; set; } } class CloudStorage : StorageDevice { public string ServerUri { get; set } public string ContainerName { get; set; } public int PortNumber { get; set; } public Guid ApiKey { get; set; } } versus: class StorageDevice { public IDictionary<string, object> Properties { get; set; } } Basically I'm on the lookout for any talks, books or articles on this approach, so I can pick up on any best practices / difficulties to avoid. Here's my main questions: Does this approach have a name? (only thing I've heard used so far is "self-describing objects") What are the best practices for persisting these dictionaries into a relational database? Especially the challenges of deserializing them successfully with strongly typed languages like C#. Does it change anything if some of the objects in the dictionary are themselves lists of strongly typed entities? Should a second dictionary be used if you want to temporarily store objects that are not to be persisted/serialized across a network, or should you use some kind of namespacing on the keys to indicate this?

• Use of c89 in GNU software

  - by Federico Culloca

  In GNU coding standard it is said that free software developer should use C89 because C99 is not widespread yet. 1999 Standard C is not widespread yet, so please do not require its features in programs. Reference here. Are they talking about developers knowledge of C99, or about compilers supporting it? Also, is this statement plausible as of today or is it somewhat "obsolete" or at least obsolescent.

• The most dangerous SQL Script in the world!

  - by DrJohn

  In my last blog entry, I outlined how to automate SQL Server database builds from concatenated SQL Scripts. However, I did not mention how I ensure the database is clean before I rebuild it. Clearly a simple DROP/CREATE DATABASE command would suffice; but you may not have permission to execute such commands, especially in a corporate environment controlled by a centralised DBA team. However, you should at least have database owner permissions on the development database so you can actually do your job! Then you can employ my universal "drop all" script which will clear down your database before you run your SQL Scripts to rebuild all the database objects. Why start with a clean database? During the development process, it is all too easy to leave old objects hanging around in the database which can have unforeseen consequences. For example, when you rename a table you may forget to delete the old table and change all the related views to use the new table. Clearly this will mean an end-user querying the views will get the wrong data and your reputation will take a nose dive as a result! Starting with a clean, empty database and then building all your database objects using SQL Scripts using the technique outlined in my previous blog means you know exactly what you have in your database. The database can then be repopulated using SSIS and bingo; you have a data mart "to go". My universal "drop all" SQL Script To ensure you start with a clean database run my universal "drop all" script which you can download from here: 100_drop_all.zip By using the database catalog views, the script finds and drops all of the following database objects: Foreign key relationships Stored procedures Triggers Database triggers Views Tables Functions Partition schemes Partition functions XML Schema Collections Schemas Types Service broker services Service broker queues Service broker contracts Service broker message types SQLCLR assemblies There are two optional sections to the script: drop users and drop roles. You may use these at your peril, particularly as you may well remove your own permissions! Note that the script has a verbose mode which displays the SQL commands it is executing. This can be switched on by setting @debug=1. Running this script against one of the system databases is certainly not recommended! So I advise you to keep a USE database statement at the top of the file. Good luck and be careful!!

• Running Objects – Associations and Relationships

  - by edurdias

  After the introduction to the Running Objects with the tutorial Movie Database in 2 Minutes (available here), I would like to demonstrate how Running Objects interprets the Associations where we will cover: Direct Association – A reference to another complex object. Aggregation – A collection of another complex object. For those coming with a database perspective, by demonstrating these associations we will also exemplify the underline relationships such as 1 to Many and Many to Many relationships...(read more)

• 3D terrain map with Hexagon Grids (XNA)

  - by Rob

  I'm working on a hobby project (I'm a web/backend developer by day) and I want to create a 3D Tile (terrain) engine. I'm using XNA, but I can use MonoGame, OpenGL, or straight DirectX, so the answer does not have to be XNA specific. I'm more looking for some high level advice on how to approach this problem. I know about creating height maps and such, there are thousands of references out there on the net for that, this is a bit more specific. I'm more concerned with is the approach to get a 3D hexagon tile grid out of my terrain (since the terrain, and all 3d objects, are basically triangles). The first approach I thought about is to basically draw the triangles on the screen in the following order (blue numbers) to give me the triangles for terrain (black triangles) and then make hexes out of the triangles (red hex). http://screencast.com/t/ebrH2g5V This approach seems complicated to me since i'm basically having to draw 4 different types of triangles. The next approach I thought of was to use the existing triangles like I did for a square grid and get my hexes from 6 triangles as follows http://screencast.com/t/w9b7qKzVJtb8 This seems like the easier approach to me since there are only 2 types of triangles (i would have to play with the heights and widths to get a "perfect" hexagon, but the idea is the same. So I'm looking for: 1) Any suggestions on which approach I should take, and why. 2) How would I translate mouse position to a hexagon grid position (especially when moving the camera around), for example in the second image if the mouse pointer were the green circle, how would I determine to highlight that hexagon and then translating that into grid coordinates (assuming it is 0,0)? 3) Any references, articles, books, etc - to get me going in the right direction. Note: I've done hex grid's and mouse-grid coordinate conversion before in 2d. looking for some pointers on how to do the same in 3d. The result I would like to achieve is something similar to the following: http :// www. youtube .com / watch?v=Ri92YkyC3fw (sorry about the youtube link, but it will only let me post 2 links in this post... same rep problem i mention below...) Thanks for any help! P.S. Sorry for not posting the images inline, I apparently don't have enough rep on this stack exchange site.

• Naming methods that perform HTTP GET/POST calls?

  - by antonpug

  In the application I am currently working on, there are generally 3 types of HTTP calls: pure GETs pure POSTs (updating the model with new data) "GET" POSTs (posting down an object to get some data back, no updates to the model) In the integration service, generally we name methods that post "postSomething()", and methods that get, "getSomething()". So my question is, if we have a "GET" POST, should the method be called: getSomething - seeing as the purpose is to obtain data postSomething - since we are technically using POST performSomeAction - arbitrary name that's more relevant to the action What are everyone's thoughts?

• NDepend 4.0 Released

  - by Anthony Trudeau

  Last week version 4.0 of NDepend was released.  NDepend is a Visual Studio add-in designed for intense code analysis with the goal of high quality code.  A month ago I wrapped up my evaluation of the previous version of NDepend. The new version contains many minor changes, several bug fixes, and adds about 50 new code rules.  The version also adds support for Visual Studio 11, .NET Framework 4.5, and SilverLight 5.0.  But, the biggest change was the shift from CQL to CQLinq. Introducing CQLinq The latest version replaces the CQL rules language with CQLinq (CQL is still an option although the editor is buried).  As you might guess CQLinq is a flavor of Linq designed specifically for the code rules. The best way to illustrate the differences is with an example.  I used the following CQL example in Part 3 of my review: WARN IF Count > 0 IN SELECT TYPES WHERE IsInterface AND !NameLike “I” This same query looks like this when implemented in CQLinq: warnif count > 0 from t in Types where t.IsInterface == true && !t.NameLike(“I”) select t I like the syntax and it is a natural fit, but I found writing the queries frustrating in the Queries and Rules Edit window.  The Queries and Rules Edit window replaces the CQL Query Edit window.  The new editor has the same style of Intellisense as the previous editor.  However, it has a few annoyances.  The error indicator is a red block.  It has the tendency of obscuring your cursor.  Additionally, writing CQLing queries is like writing plain old Linq queries, so the fact that the editor uses Enter to select from Intellisense instead of Tab is jarring.  These issues can be an obstacle to writing queries quickly.CQLinq makes it possible to write rules that weren't possible before.  Additionally, a JustMyCode domain is now possible making it easy to eliminate generated code from the analysis.Should you Buy? I recommend NDepend overall.  It has some rough points for me that I have detailed in my earlier evaluation (starting here).  But, it’s definitely worth the money.  The bigger question is: should I pay for the upgrade to 4.0?  At this point I’m on the fence, but I would go for it if you need support for Visual Studio 2011, .NET Framework 4.5, or Silverlight 5.0; or if you need one of the many rules that weren't possible before CQLinq. Disclaimer: Patrick Smacchia contacted me about reviewing NDepend. I received a free license in return for sharing my experiences and talking about the capabilities of the add-in on this site. There is no expectation of a positive review elicited from the author of NDepend. Resources: NDepend Release Notes

• When Is It Acceptable to NOT Fix Broken Windows?

  - by Bullines

  In reference to broken windows... Are there times when refactoring is best left for a future activity? For example, if a project to add some new features to an existing internal system is assigned to a team that has not worked with the system until now, and is given a short timeline in which to work with - can it be ever be justifiable to defer major refactorings to existing code for the sake of making the deadline in this scenario?

Here is another example of one of the latest improvements: Contract Lifecycle Management for Public Sector, or CLM. The latest EBS module geared specifically for the Federal acquisition community. Our existing customers have been asking Oracle for years to upgrade its Advanced Procurement Suite to meet the complex procurement processes of the Federal Government. You asked; we listened. Oracle, with direct input from Federal agencies, subject matter experts, integration partners, and the Federal acquisition community, has expanded and deepened its procurement suite to meet the unique demands of the Federal acquisition community. New benefits/features include: Contract Line Item/Sub-Line Item (CLIN/SLIN) structures Configurable Document Numbering Complex Pricing Contract Types ( as per FAR Part 16) Option lines and exercising of options Incremental Funding capability Support for multiple document types (delivery orders, BPA call orders, awards, agreements, IDIQ contracts) Requisition lines to fund modifications Workload assignment and milestones Contract Action Reporting to FPDS-NG I’ve been conducting many tests over the past few months and have been quite impressed with the depth of features and the seamless integration to Federal Financials, specifically the funds control within the financials. Again, thank you for reading. If you have suggestions for future posts, please leave them in the comments section and I’ll take it from there.
