• How do programmers deal with Project Lead/Managers?

  - by Simon

  Project Managers/Technical Leads sometimes tend to be over enthusiastic when it comes to software. But during code reviews if instead of functionality of the code the only complain one hears is about formatting/spacing and similar trivial things, when there are far better things to discuss (Among other things I have noticed the sometimes during the so called "reviews" suggestions are made that implementation needs a re-write just because it doesnt use the most happening technology/buzzword) How do fellow programmers deal with such scenarios? or is this just a one off? (or is the fault entirely on me )If you have similar experience and what you did to overcome it? Feel free to share.

• Maintaining packages with code - Adding a property expression programmatically

  Every now and then I've come across scenarios where I need to update a lot of packages all in the same way. The usual scenario revolves around a group of packages all having been built off the same package template, and something needs to updated to keep up with new requirements, a new logging standard for example.You'd probably start by updating your template package, but then you need to address all your existing packages. Often this can run into the hundreds of packages and clearly that's not a job anyone wants to do by hand. I normally solve the problem by writing a simple console application that looks for files and patches any package it finds, and it is an example of this I'd thought I'd tidy up a bit and publish here. This sample will look at the package and find any top level Execute SQL Tasks, and change the SQL Statement property to use an expression. It is very simplistic working on top level tasks only, so nothing inside a Sequence Container or Loop will be checked but obviously the code could be extended for this if required. The code that actually sets the expression is shown below, the rest is just wrapper code to find the package and to find the task. /// <summary> /// The CreationName of the Tasks to target, e.g. Execute SQL Task /// </summary> private const string TargetTaskCreationName = "Microsoft.SqlServer.Dts.Tasks.ExecuteSQLTask.ExecuteSQLTask, Microsoft.SqlServer.SQLTask, Version=9.0.242.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91"; /// <summary> /// The name of the task property to target. /// </summary> private const string TargetPropertyName = "SqlStatementSource"; /// <summary> /// The property expression to set. /// </summary> private const string ExpressionToSet = "@[User::SQLQueryVariable]"; .... // Check if the task matches our target task type if (taskHost.CreationName == TargetTaskCreationName) { // Check for the target property if (taskHost.Properties.Contains(TargetPropertyName)) { // Get the property, check for an expression and set expression if not found DtsProperty property = taskHost.Properties[TargetPropertyName]; if (string.IsNullOrEmpty(property.GetExpression(taskHost))) { property.SetExpression(taskHost, ExpressionToSet); changeCount++; } } } This is a console application, so to specify which packages you want to target you have three options: Find all packages in the current folder, the default behaviour if no arguments are specified TaskExpressionPatcher.exe .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } Find all packages in a specified folder, pass the folder as the argument TaskExpressionPatcher.exe C:\Projects\Alpha\Packages\ .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } Find a specific package, pass the file path as the argument TaskExpressionPatcher.exe C:\Projects\Alpha\Packages\Package.dtsx The code was written against SQL Server 2005, but just change the reference to Microsoft.SQLServer.ManagedDTS to be the SQL Server 2008 version and it will work fine. If you get an error Microsoft.SqlServer.Dts.Runtime.DtsRuntimeException: The package failed to load due to error 0xC0011008… then check that the package is from the correct version of SSIS compared to the referenced assemblies, 2005 vs 2008 in other words.

• How do you deal with intentionally bad code?

  - by mafutrct

  There are many stories about intentionally bad code, not only on TDWTF but also on SO. Typical cases include: Having a useless time-wasting construct (e.g. an empty loop counting to some huge value) so programmers can easily "speed up" the application by removing it when they are tasked to. Providing intentionally misleading, wrong or no documentation to generate expensive support requests. Readily generating errors, or worse, generating even though everything worked fine, locking up the application so an expensive support call is required to unlock. These points display a more or less malicious attitude (even though sometimes by accident), especially the first point occurs rather often. How should one deal with such constructs? Ignore the issue, or just remove the offending code? Notify their manager, or speak to the person who introduced the "feature"?

• Is there any reason to use "plain old data" classes?

  - by Michael

  In legacy code I occasionally see classes that are nothing but wrappers for data. something like: class Bottle { int height; int diameter; Cap capType; getters/setters, maybe a constructor } My understanding of OO is that classes are structures for data and the methods of operating on that data. This seems to preclude objects of this type. To me they are nothing more than structs and kind of defeat the purpose of OO. I don't think it's necessarily evil, though it may be a code smell. Is there a case where such objects would be necessary? If this is used often, does it make the design suspect?

• How do I overcome paralysis by analysis when coding?

  - by LuxuryMode

  When I start a new project, I often times immediately start thinking about the details of implementation. "Where am I gonna put the DataBaseHandler? How should I use it? Should classes that want to use it extend from some Abstract superclass..? Should I an interface? What level of abstraction am I going to use in my class that contains methods for sending requests and parsing data?" I end up stalling for a long time because I want to code for extensibility and reusability. But I feel it almost impossible to get past thinking about how to implement perfectly. And then, if I try to just say "screw it, just get it done!", I hit a brick wall pretty quickly because my code isn't organized, I mixed levels of abstractions, etc. What are some techniques/methods you have for launching into a new project while also setting up a logical/modular structure that will scale well?

• *Code owner* system: is it an efficient way?

  - by sergzach

  There is a new developer in our team. An agile methodology is in use at our company. But the developer has another experience: he considers that particular parts of the code must be assigned to particular developers. So if one developer had created a program procedure or module it would be considered normal that all changes of the procedure/module would be made by him only. On the plus side, supposedly with the proposed approach we save common development time, because each developer knows his part of the code well and makes fixes fast. The downside is that developers don't know the system entirely. Do you think the approach will work well for a medium size system (development of a social network site)?

• Is there any reason to use "container" classes?

  - by Michael

  I realize the term "container" is misleading in this context - if anyone can think of a better term please edit it in.

• I sold my source code to a client, can I now re-build similar code and sell to someone else?

  - by flashhag

  So we built a website and software for a client, charged our fee and handed over the code. The client then got a request from another company about the software. The client passed on the request but said since they owned the code they would need to recieve money for it. I'm thinking there are 2 options here: Work with the client as requested We've actually re-built the software, made it much better and use it for other projects. Am i in my rights to sell that direct to the company that enquired about it instead of going through the client? Any help on this would be much appreciated

• Organizing code for iOS app development

  - by KronoS

  I've been developing an app for the iOS platform, and as I've been going along, I've noticed that I've done a terrible job of keeping my files (.h, .m, .mm) organized. Is there any industry standards or best practices when it comes to organizing files for an iOS project? My files include custom classes (beside the view controllers), customized View Controllers, third-party content, code that works only on iOS 5.0+ and code that works on previous versions. What I'm looking for is a solution to keep things organized in a manner that others (or myself in years to come) can look at this and understand the basic structure of the application and not get lost in the multiple files found therein.

• HG: fork web app project to separate API code from app code

  - by cs_brandt

  I have a web app thats been in active development for about 8 months now and its becoming apparent that the project has a need to maintain a separation between app specific code and our OO Javascript API. What I would like to do is have another repository with the following general structure of the js API code. repo_name | +---build | +---build_tools | +---doc | +---src | +---js Of course this structure is different from the original web app directory structure. If I make changes to this new repository how could I pull in those changes to the web app repository without unintentionally removing files or modifying the directory structure of the web app repository?

• Is extensive documentation a code smell?

  - by Griffin

  Every library, open-source project, and SDK/API I've ever come across has come packaged with a (usually large) documentation file, and this seems contradictory to the wide-spread belief that good code needs little to no comments. What separates documentation from this programming methodology? a one to two page overview of a package seems reasonable, but elegant code combined with standard intelisense should have theoretically deprecated the practice of documentation by now IMO. I feel like companies only create detailed documentation and tutorials because its what they've always done. Why should developers have to constantly be searching through online documentation in order to learn how to do things when such information should be intrinsic to the classes, methods and namespaces?

• Which is more maintainable -- boolean assignment via if/else or boolean expression?

  - by Bret Walker

  Which would be considered more maintainable? if (a == b) c = true; else c = false; or c = (a == b); I've tried looking in Code Complete, but can't find an answer. I think the first is more readable (you can literally read it out loud), which I also think makes it more maintainable. The second one certainly makes more sense and reduces code, but I'm not sure it's as maintainable for C# developers (I'd expect to see this idiom more in, for example, Python).

• Nested languages code smell

  - by l0b0

  Many projects combine languages, for example on the web with the ubiquitous SQL + server-side language + markup du jour + JavaScript + CSS mix (often in a single function). Bash and other shell code is mixed with Perl and Python on the server side, evaled and sometimes even passed through sed before execution. Many languages support runtime execution of arbitrary code strings, and in some it seems to be fairly common practice. In addition to advice about security and separation of concerns, what other issues are there with this type of programming, what can be done to minimize it, and is it ever defensible (except in the "PHB on the shoulder" situation)?

• Resources on learning to program in machine code?

  - by AceofSpades

  I'm a student, fresh into programming and loving it, from Java to C++ and down to C. I moved backwards to the barebones and thought to go further down to Assembly. But, to my surprise, a lot of people said it's not as fast as C and there is no use. They suggested learning either how to program a kernel or writing a C compiler. My dream is to learn to program in binary (machine code) or maybe program bare metal (program micro-controller physically) or write bios or boot loaders or something of that nature. The only possible thing I heard after so much research is that a hex editor is the closest thing to machine language I could find in this age and era. Are there other things I'm unaware of? Are there any resources to learn to program in machine code? Preferably on a 8-bit micro-controller/microprocessor. This question is similar to mine, but I'm interested in practical learning first and then understanding the theory.

• Coordinating team code review sessions [closed]

  - by Wade Tandy

  My question has two parts: 1) In your team or organization, do you ever do in-person code reviews with all or part of a team, as opposed to online reviews using some sort of tool? 2) How do you structure these meetings? Do you choose to focus on one person's code in a given meeting? Do you look at everything? Take a random sample? Ask people on the team what they'd like to have looked at of theirs? I'd love to add this practice to my development team, so I'd like to hear how others are doing it.

• OBIEE 11.1.1 - Introduction to OBIEE 11g Full Sample App

  - by user809526

  Isn't it nice to discover OBIEE 11g around a nice "How To" catalog of features? to observe OBI and Essbase relationships at work? to discover TimesTen? The OBIEE 11g Full Sample App (FSA) is a comprehensive collection of examples designed to demonstrate the latest Oracle BIEE 11g capabilities and design best practices: Enhanced visualizations as Geo-spacial maps and interactive dashboards, Action Framework,  BI Publisher, Scorecard and Strategy Management, Mobile style sheets, Semantic layer modeling, Multi-source federation, Integration with products such as Essbase, Oracle OLAP, ODM, TimesTen, ODI and more The FSA is intended to be comprehensive, it is big (see CAVEAT below). The FSA is not an Oracle product, it is a good will free deployment of OBIEE/Essbase designed to exemplify OBIEE features, infrastructure and security around the Fusion Middleware components. Its contents and code are distributed free for demonstrative purposes only. It is neither maintained nor supported by Oracle as a licensed product. The OBIEE Full Sample App is independent of the default Sample App that comes with the OBIEE product. BENEFITS The FSA helps as a demonstrator of OBIEE 11g best practices, a tutorial, an environment "Test & Scrap", a SR bench (regression, conflicts), a tuning bench, a quick ready made POC seed for projects, a security options environment, ... The FSA - Is organized around a catalog of functional features - Has been deployed over 1000 times, it should be stable RELEASE The Full Sample App (V107) is bound to OBIEE 11.1.1.5 and Essbase 11.1.2.1 (November 2011). The FSA release dates are independent of the Product GA date (OBIEE). In early December 2011, a new functional Patch (V110) is released. It is easily applied (in less than 15 mins) on top of OBIEE SampleApp 11.1.1.5 (V107). The patch (V110) includes additional functional examples:        1. Web Catalog Statistics Application: Provides detailed insight into your web catalog content, dormant catalog objects, webcat impact analysis for metadata changes and more        2. Data inflation Scripts: A set of simple SQL procedures to quickly inflate SampleApp Fact and Dimension data to millions of records in a few minutes        3. Public Content Extensions Framework: A patching framework for public examples and contributions leveraging SampleApp        4. Additional report examples (including bridge report, external chart integrations) and bug fixes DISTRIBUTION as VBox image (November 2011) The ready made VBox image is designed to run on Virtual Box.

• Inheritance Mapping Strategies with Entity Framework Code First CTP5: Part 2 – Table per Type (TPT)

  - by mortezam

  In the previous blog post you saw that there are three different approaches to representing an inheritance hierarchy and I explained Table per Hierarchy (TPH) as the default mapping strategy in EF Code First. We argued that the disadvantages of TPH may be too serious for our design since it results in denormalized schemas that can become a major burden in the long run. In today’s blog post we are going to learn about Table per Type (TPT) as another inheritance mapping strategy and we'll see that TPT doesn’t expose us to this problem. Table per Type (TPT)Table per Type is about representing inheritance relationships as relational foreign key associations. Every class/subclass that declares persistent properties—including abstract classes—has its own table. The table for subclasses contains columns only for each noninherited property (each property declared by the subclass itself) along with a primary key that is also a foreign key of the base class table. This approach is shown in the following figure: For example, if an instance of the CreditCard subclass is made persistent, the values of properties declared by the BillingDetail base class are persisted to a new row of the BillingDetails table. Only the values of properties declared by the subclass (i.e. CreditCard) are persisted to a new row of the CreditCards table. The two rows are linked together by their shared primary key value. Later, the subclass instance may be retrieved from the database by joining the subclass table with the base class table. TPT Advantages The primary advantage of this strategy is that the SQL schema is normalized. In addition, schema evolution is straightforward (modifying the base class or adding a new subclass is just a matter of modify/add one table). Integrity constraint definition are also straightforward (note how CardType in CreditCards table is now a non-nullable column). Another much more important advantage is the ability to handle polymorphic associations (a polymorphic association is an association to a base class, hence to all classes in the hierarchy with dynamic resolution of the concrete class at runtime). A polymorphic association to a particular subclass may be represented as a foreign key referencing the table of that particular subclass. Implement TPT in EF Code First We can create a TPT mapping simply by placing Table attribute on the subclasses to specify the mapped table name (Table attribute is a new data annotation and has been added to System.ComponentModel.DataAnnotations namespace in CTP5): public abstract class BillingDetail {     public int BillingDetailId { get; set; }     public string Owner { get; set; }     public string Number { get; set; } } [Table("BankAccounts")] public class BankAccount : BillingDetail {     public string BankName { get; set; }     public string Swift { get; set; } } [Table("CreditCards")] public class CreditCard : BillingDetail {     public int CardType { get; set; }     public string ExpiryMonth { get; set; }     public string ExpiryYear { get; set; } } public class InheritanceMappingContext : DbContext {     public DbSet<BillingDetail> BillingDetails { get; set; } } If you prefer fluent API, then you can create a TPT mapping by using ToTable() method: protected override void OnModelCreating(ModelBuilder modelBuilder) {     modelBuilder.Entity<BankAccount>().ToTable("BankAccounts");     modelBuilder.Entity<CreditCard>().ToTable("CreditCards"); } Generated SQL For QueriesLet’s take an example of a simple non-polymorphic query that returns a list of all the BankAccounts: var query = from b in context.BillingDetails.OfType<BankAccount>() select b; Executing this query (by invoking ToList() method) results in the following SQL statements being sent to the database (on the bottom, you can also see the result of executing the generated query in SQL Server Management Studio): Now, let’s take an example of a very simple polymorphic query that requests all the BillingDetails which includes both BankAccount and CreditCard types: projects some properties out of the base class BillingDetail, without querying for anything from any of the subclasses: var query = from b in context.BillingDetails             select new { b.BillingDetailId, b.Number, b.Owner }; -- var query = from b in context.BillingDetails select b; This LINQ query seems even more simple than the previous one but the resulting SQL query is not as simple as you might expect: -- As you can see, EF Code First relies on an INNER JOIN to detect the existence (or absence) of rows in the subclass tables CreditCards and BankAccounts so it can determine the concrete subclass for a particular row of the BillingDetails table. Also the SQL CASE statements that you see in the beginning of the query is just to ensure columns that are irrelevant for a particular row have NULL values in the returning flattened table. (e.g. BankName for a row that represents a CreditCard type) TPT ConsiderationsEven though this mapping strategy is deceptively simple, the experience shows that performance can be unacceptable for complex class hierarchies because queries always require a join across many tables. In addition, this mapping strategy is more difficult to implement by hand— even ad-hoc reporting is more complex. This is an important consideration if you plan to use handwritten SQL in your application (For ad hoc reporting, database views provide a way to offset the complexity of the TPT strategy. A view may be used to transform the table-per-type model into the much simpler table-per-hierarchy model.) SummaryIn this post we learned about Table per Type as the second inheritance mapping in our series. So far, the strategies we’ve discussed require extra consideration with regard to the SQL schema (e.g. in TPT, foreign keys are needed). This situation changes with the Table per Concrete Type (TPC) that we will discuss in the next post.

• making graph/map of functions/methods calls in c# code (visual studio 2008)

  - by Y. Shoham

  I have some c# projects in visual studio 2008, and I want to get graph (map? table?) of all methods calls. I want it static, not runtime (like "call stack"); any function - who calls it, and how many times, etc. I can Find All References method after method, and copy each call to table or Graphviz file, but it will take few hours. Is there an automatic tool or plugin that can help?

• Can this be considered Clean Code / Best Practice?

  - by MRFerocius

  Guys, How are you doing today? I have the following question because I will follow this strategy for all my helpers (to deal with the DB entities) Is this considered a good practice or is it going to be unmaintainable later? public class HelperArea : AbstractHelper { event OperationPerformed<Area> OnAreaInserting; event OperationPerformed<Area> OnAreaInserted; event OperationPerformed<Area> OnExceptionOccured; public void Insert(Area element) { try { if (OnAreaInserting != null) OnAreaInserting(element); DBase.Context.Areas.InsertOnSubmit(new AtlasWFM_Mapping.Mapping.Area { areaDescripcion = element.Description, areaNegocioID = element.BusinessID, areaGUID = Guid.NewGuid(), areaEstado = element.Status, }); DBase.Context.SubmitChanges(); if (OnAreaInserted != null) OnAreaInserted(element); } catch (Exception ex) { LogManager.ChangeStrategy(LogginStrategies.EVENT_VIEWER); LogManager.LogError(new LogInformation { logErrorType = ErrorType.CRITICAL, logException = ex, logMensaje = "Error inserting Area" }); if (OnExceptionOccured != null) OnExceptionOccured(elemento); } } I want to know if it is a good way to handle the event on the Exception to let subscribers know that there has been an exception inserting that Area. And the way to log the Exception, is is OK to do it this way? Any suggestion to make it better?

• How can I hide tracing code in Visual Studio IDE C# ?

  - by Mark

  As I'm starting to put more tracing in my code, i'm realizing it adds a lot of clutter. I know Visual Studio allows you to hide and reveal code, however, i'd like to be able group code into "tracing" code and then hide it and reveal at will as i'm reading the code. I suppose it could do this either per file or per class or per function. Is there any way to do this? What do you guys do? Adding some clarification The hide current feature kind of allows you to do this except that when the code is hidden, you can't tell if its tracing or not. You also can't say "hide all tracing code" and "reveal all tracing code" which is useful when reading a function depending on what you are trying to do.
