  • How to host a RESTful C# webservice and test it.

    - by Debby
    Hi, I need to create a RESTful webservice in C#. This is what I have right now: namespace WebService { [ServiceContract] public interface IService { [OperationContract(Name="Add")] [WebGet(UriTemplate = "/")] int Add(); } public class Service:IService { public int Add() { // do some calculations and return result return res; } } } Now, my question is How do i host this service at a location say (http://localhost/TestService) and how can i test the service in console application client?

  • overriding callbacks avoiding attribute pollution

    - by pygabriel
    I've a class that has some callbacks and its own interface, something like: class Service: def __init__(self): connect("service_resolved", self.service_resolved) def service_resolved(self, a,b c): ''' This function is called when it's triggered service resolved signal and has a lot of parameters''' the connect function is for example the gtkwidget.connect, but I want that this connection is something more general, so I've decided to use a "twisted like" approach: class MyService(Service): def my_on_service_resolved(self, little_param): ''' it's a decorated version of srvice_resolved ''' def service_resolved(self,a,b,c): super(MyService,self).service_resolved(a,b,c) little_param = "something that's obtained from a,b,c" self.my_on_service_resolved(little_param) So I can use MyService by overriding my_on_service_resolved. The problem is the "attributes" pollution. In the real implementation, Service has some attributes that can accidentally be overriden in MyService and those who subclass MyService. How can I avoid attribute pollution? What I've thought is a "wrapper" like approach but I don't know if it's a good solution: class WrapperService(): def __init__(self): self._service = service_resolved # how to override self._service.service_resolved callback? def my_on_service_resolved(self,param): ''' '''

  • Fake location for the device (custom)

    - by AtomRiot
    I know there are a few apps out there to fake a devices location but specifically what i want to do is use a location grabbed from a url. What direction should I look for setting the location on the device. The scenario i have is a jailbroken Wi-Fi iPad tethered to a nexus one. The nexus one would host a background service that when a request is recieved, it would respond with gps data of its current location. The jailbroken ipad would have a background service that either updated the location on a time interval, or on a per request basis (depending on how i have to implement it) by submitting a request to the tethered nexus one service. That data would then be set on the ipad and an application requesting location would get the service data. The goal is to recreate the location faker app's functionality with the exception of the spoofed location comes from the nexus ones gps via the service but i have not yet found out how to set the location data for the device. I can ofcourse implement this in a per app basis but it would be awesome to have any app be able to use it.

  • Using the HttpWebRequest class.

    - by Nick
    I instantiate the HttpWebRequest object: HttpWebRequest httpWebRequest = WebRequest.Create("http://game.stop.com/webservice/services/gameup") as HttpWebRequest; When I "post" the data to this service, how does the service know which web method to submit the data to? I do not have the code to this web service, all I know is that it was written in Java.

  • Printing a list using reflection

    - by TFool
    public class Service{ String serviceName; //setter and getter } public class Version{ String VersionID; //setter and getter } public void test(Object list){ //it shd print the obtained list } List< Service list1; //Service is a Bean List< Version list2; //Version is a Bean test(list1); test(list2); Now the test method shd print the obtained list - (i.e) If the list is of type Service ,then serviceName should be printed using its getter. If the list type is Version versionID should be printed. Is it possible to achieve this without using Interface or abstract class?

  • WebService remote invoking fails.

    - by user569913
    I have a web service hosted on a web server, I invoke the web service using jquery ajax. The service returns results successfully when invoked locally from the server, but it fails when invoked from a remote client machine (not in the same domain). I see the request fail in the firebug returning error (401 UnAuthorized) and the response has the following error (Request format is unrecognized for URL unexpectedly ending in '/List').

  • how do i consume net.tcp binding within web project?

    - by user1871124
    I'm working on a web application using mvc, we have already a service that does http binding, the client wants tcp binding for certain actions (not really sure why) but it's their requirement so i'm attempting to set up net.tcp binding, all references i am seeing to doing this involve a windows application and not a web application. I guess my question has 2 parts, first can you run httpbinding and net.tcp binding at the same time through the same service/project. secondly how would I consume the service through a webproject?

  • Guaranteed way to force application running continuously (overriding taskkill, task manager etc.)

    - by Alex
    I have a C# security/monitoring application that I need to have running no matter what. However, I can not remove privileges or restrict access to parts of the OS (Windows). I thought of having a protection service running which monitors continuously if an application is running, and starts it back up when the application is killed somehow, while the application monitors the protection service and starts the service if the service is killed. To my knowledge you can't simultaneously kill multiple processes at the same time. Any better idea to guarantee that an application is always running?

  • New features of C# 4.0

    This article covers New features of C# 4.0. Article has been divided into below sections. Introduction. Dynamic Lookup. Named and Optional Arguments. Features for COM interop. Variance. Relationship with Visual Basic. Resources. Other interested readings… 22 New Features of Visual Studio 2008 for .NET Professionals 50 New Features of SQL Server 2008 IIS 7.0 New features Introduction It is now close to a year since Microsoft Visual C# 3.0 shipped as part of Visual Studio 2008. In the VS Managed Languages team we are hard at work on creating the next version of the language (with the unsurprising working title of C# 4.0), and this document is a first public description of the planned language features as we currently see them. Please be advised that all this is in early stages of production and is subject to change. Part of the reason for sharing our plans in public so early is precisely to get the kind of feedback that will cause us to improve the final product before it rolls out. Simultaneously with the publication of this whitepaper, a first public CTP (community technology preview) of Visual Studio 2010 is going out as a Virtual PC image for everyone to try. Please use it to play and experiment with the features, and let us know of any thoughts you have. We ask for your understanding and patience working with very early bits, where especially new or newly implemented features do not have the quality or stability of a final product. The aim of the CTP is not to give you a productive work environment but to give you the best possible impression of what we are working on for the next release. The CTP contains a number of walkthroughs, some of which highlight the new language features of C# 4.0. Those are excellent for getting a hands-on guided tour through the details of some common scenarios for the features. You may consider this whitepaper a companion document to these walkthroughs, complementing them with a focus on the overall language features and how they work, as opposed to the specifics of the concrete scenarios. C# 4.0 The major theme for C# 4.0 is dynamic programming. Increasingly, objects are “dynamic” in the sense that their structure and behavior is not captured by a static type, or at least not one that the compiler knows about when compiling your program. Some examples include a. objects from dynamic programming languages, such as Python or Ruby b. COM objects accessed through IDispatch c. ordinary .NET types accessed through reflection d. objects with changing structure, such as HTML DOM objects While C# remains a statically typed language, we aim to vastly improve the interaction with such objects. A secondary theme is co-evolution with Visual Basic. Going forward we will aim to maintain the individual character of each language, but at the same time important new features should be introduced in both languages at the same time. They should be differentiated more by style and feel than by feature set. The new features in C# 4.0 fall into four groups: Dynamic lookup Dynamic lookup allows you to write method, operator and indexer calls, property and field accesses, and even object invocations which bypass the C# static type checking and instead gets resolved at runtime. Named and optional parameters Parameters in C# can now be specified as optional by providing a default value for them in a member declaration. When the member is invoked, optional arguments can be omitted. Furthermore, any argument can be passed by parameter name instead of position. COM specific interop features Dynamic lookup as well as named and optional parameters both help making programming against COM less painful than today. On top of that, however, we are adding a number of other small features that further improve the interop experience. Variance It used to be that an IEnumerable<string> wasn’t an IEnumerable<object>. Now it is – C# embraces type safe “co-and contravariance” and common BCL types are updated to take advantage of that. Dynamic Lookup Dynamic lookup allows you a unified approach to invoking things dynamically. With dynamic lookup, when you have an object in your hand you do not need to worry about whether it comes from COM, IronPython, the HTML DOM or reflection; you just apply operations to it and leave it to the runtime to figure out what exactly those operations mean for that particular object. This affords you enormous flexibility, and can greatly simplify your code, but it does come with a significant drawback: Static typing is not maintained for these operations. A dynamic object is assumed at compile time to support any operation, and only at runtime will you get an error if it wasn’t so. Oftentimes this will be no loss, because the object wouldn’t have a static type anyway, in other cases it is a tradeoff between brevity and safety. In order to facilitate this tradeoff, it is a design goal of C# to allow you to opt in or opt out of dynamic behavior on every single call. The dynamic type C# 4.0 introduces a new static type called dynamic. When you have an object of type dynamic you can “do things to it” that are resolved only at runtime: dynamic d = GetDynamicObject(…); d.M(7); The C# compiler allows you to call a method with any name and any arguments on d because it is of type dynamic. At runtime the actual object that d refers to will be examined to determine what it means to “call M with an int” on it. The type dynamic can be thought of as a special version of the type object, which signals that the object can be used dynamically. It is easy to opt in or out of dynamic behavior: any object can be implicitly converted to dynamic, “suspending belief” until runtime. Conversely, there is an “assignment conversion” from dynamic to any other type, which allows implicit conversion in assignment-like constructs: dynamic d = 7; // implicit conversion int i = d; // assignment conversion Dynamic operations Not only method calls, but also field and property accesses, indexer and operator calls and even delegate invocations can be dispatched dynamically: dynamic d = GetDynamicObject(…); d.M(7); // calling methods d.f = d.P; // getting and settings fields and properties d[“one”] = d[“two”]; // getting and setting thorugh indexers int i = d + 3; // calling operators string s = d(5,7); // invoking as a delegate The role of the C# compiler here is simply to package up the necessary information about “what is being done to d”, so that the runtime can pick it up and determine what the exact meaning of it is given an actual object d. Think of it as deferring part of the compiler’s job to runtime. The result of any dynamic operation is itself of type dynamic. Runtime lookup At runtime a dynamic operation is dispatched according to the nature of its target object d: COM objects If d is a COM object, the operation is dispatched dynamically through COM IDispatch. This allows calling to COM types that don’t have a Primary Interop Assembly (PIA), and relying on COM features that don’t have a counterpart in C#, such as indexed properties and default properties. Dynamic objects If d implements the interface IDynamicObject d itself is asked to perform the operation. Thus by implementing IDynamicObject a type can completely redefine the meaning of dynamic operations. This is used intensively by dynamic languages such as IronPython and IronRuby to implement their own dynamic object models. It will also be used by APIs, e.g. by the HTML DOM to allow direct access to the object’s properties using property syntax. Plain objects Otherwise d is a standard .NET object, and the operation will be dispatched using reflection on its type and a C# “runtime binder” which implements C#’s lookup and overload resolution semantics at runtime. This is essentially a part of the C# compiler running as a runtime component to “finish the work” on dynamic operations that was deferred by the static compiler. Example Assume the following code: dynamic d1 = new Foo(); dynamic d2 = new Bar(); string s; d1.M(s, d2, 3, null); Because the receiver of the call to M is dynamic, the C# compiler does not try to resolve the meaning of the call. Instead it stashes away information for the runtime about the call. This information (often referred to as the “payload”) is essentially equivalent to: “Perform an instance method call of M with the following arguments: 1. a string 2. a dynamic 3. a literal int 3 4. a literal object null” At runtime, assume that the actual type Foo of d1 is not a COM type and does not implement IDynamicObject. In this case the C# runtime binder picks up to finish the overload resolution job based on runtime type information, proceeding as follows: 1. Reflection is used to obtain the actual runtime types of the two objects, d1 and d2, that did not have a static type (or rather had the static type dynamic). The result is Foo for d1 and Bar for d2. 2. Method lookup and overload resolution is performed on the type Foo with the call M(string,Bar,3,null) using ordinary C# semantics. 3. If the method is found it is invoked; otherwise a runtime exception is thrown. Overload resolution with dynamic arguments Even if the receiver of a method call is of a static type, overload resolution can still happen at runtime. This can happen if one or more of the arguments have the type dynamic: Foo foo = new Foo(); dynamic d = new Bar(); var result = foo.M(d); The C# runtime binder will choose between the statically known overloads of M on Foo, based on the runtime type of d, namely Bar. The result is again of type dynamic. The Dynamic Language Runtime An important component in the underlying implementation of dynamic lookup is the Dynamic Language Runtime (DLR), which is a new API in .NET 4.0. The DLR provides most of the infrastructure behind not only C# dynamic lookup but also the implementation of several dynamic programming languages on .NET, such as IronPython and IronRuby. Through this common infrastructure a high degree of interoperability is ensured, but just as importantly the DLR provides excellent caching mechanisms which serve to greatly enhance the efficiency of runtime dispatch. To the user of dynamic lookup in C#, the DLR is invisible except for the improved efficiency. However, if you want to implement your own dynamically dispatched objects, the IDynamicObject interface allows you to interoperate with the DLR and plug in your own behavior. This is a rather advanced task, which requires you to understand a good deal more about the inner workings of the DLR. For API writers, however, it can definitely be worth the trouble in order to vastly improve the usability of e.g. a library representing an inherently dynamic domain. Open issues There are a few limitations and things that might work differently than you would expect. · The DLR allows objects to be created from objects that represent classes. However, the current implementation of C# doesn’t have syntax to support this. · Dynamic lookup will not be able to find extension methods. Whether extension methods apply or not depends on the static context of the call (i.e. which using clauses occur), and this context information is not currently kept as part of the payload. · Anonymous functions (i.e. lambda expressions) cannot appear as arguments to a dynamic method call. The compiler cannot bind (i.e. “understand”) an anonymous function without knowing what type it is converted to. One consequence of these limitations is that you cannot easily use LINQ queries over dynamic objects: dynamic collection = …; var result = collection.Select(e => e + 5); If the Select method is an extension method, dynamic lookup will not find it. Even if it is an instance method, the above does not compile, because a lambda expression cannot be passed as an argument to a dynamic operation. There are no plans to address these limitations in C# 4.0. Named and Optional Arguments Named and optional parameters are really two distinct features, but are often useful together. Optional parameters allow you to omit arguments to member invocations, whereas named arguments is a way to provide an argument using the name of the corresponding parameter instead of relying on its position in the parameter list. Some APIs, most notably COM interfaces such as the Office automation APIs, are written specifically with named and optional parameters in mind. Up until now it has been very painful to call into these APIs from C#, with sometimes as many as thirty arguments having to be explicitly passed, most of which have reasonable default values and could be omitted. Even in APIs for .NET however you sometimes find yourself compelled to write many overloads of a method with different combinations of parameters, in order to provide maximum usability to the callers. Optional parameters are a useful alternative for these situations. Optional parameters A parameter is declared optional simply by providing a default value for it: public void M(int x, int y = 5, int z = 7); Here y and z are optional parameters and can be omitted in calls: M(1, 2, 3); // ordinary call of M M(1, 2); // omitting z – equivalent to M(1, 2, 7) M(1); // omitting both y and z – equivalent to M(1, 5, 7) Named and optional arguments C# 4.0 does not permit you to omit arguments between commas as in M(1,,3). This could lead to highly unreadable comma-counting code. Instead any argument can be passed by name. Thus if you want to omit only y from a call of M you can write: M(1, z: 3); // passing z by name or M(x: 1, z: 3); // passing both x and z by name or even M(z: 3, x: 1); // reversing the order of arguments All forms are equivalent, except that arguments are always evaluated in the order they appear, so in the last example the 3 is evaluated before the 1. Optional and named arguments can be used not only with methods but also with indexers and constructors. Overload resolution Named and optional arguments affect overload resolution, but the changes are relatively simple: A signature is applicable if all its parameters are either optional or have exactly one corresponding argument (by name or position) in the call which is convertible to the parameter type. Betterness rules on conversions are only applied for arguments that are explicitly given – omitted optional arguments are ignored for betterness purposes. If two signatures are equally good, one that does not omit optional parameters is preferred. M(string s, int i = 1); M(object o); M(int i, string s = “Hello”); M(int i); M(5); Given these overloads, we can see the working of the rules above. M(string,int) is not applicable because 5 doesn’t convert to string. M(int,string) is applicable because its second parameter is optional, and so, obviously are M(object) and M(int). M(int,string) and M(int) are both better than M(object) because the conversion from 5 to int is better than the conversion from 5 to object. Finally M(int) is better than M(int,string) because no optional arguments are omitted. Thus the method that gets called is M(int). Features for COM interop Dynamic lookup as well as named and optional parameters greatly improve the experience of interoperating with COM APIs such as the Office Automation APIs. In order to remove even more of the speed bumps, a couple of small COM-specific features are also added to C# 4.0. Dynamic import Many COM methods accept and return variant types, which are represented in the PIAs as object. In the vast majority of cases, a programmer calling these methods already knows the static type of a returned object from context, but explicitly has to perform a cast on the returned value to make use of that knowledge. These casts are so common that they constitute a major nuisance. In order to facilitate a smoother experience, you can now choose to import these COM APIs in such a way that variants are instead represented using the type dynamic. In other words, from your point of view, COM signatures now have occurrences of dynamic instead of object in them. This means that you can easily access members directly off a returned object, or you can assign it to a strongly typed local variable without having to cast. To illustrate, you can now say excel.Cells[1, 1].Value = "Hello"; instead of ((Excel.Range)excel.Cells[1, 1]).Value2 = "Hello"; and Excel.Range range = excel.Cells[1, 1]; instead of Excel.Range range = (Excel.Range)excel.Cells[1, 1]; Compiling without PIAs Primary Interop Assemblies are large .NET assemblies generated from COM interfaces to facilitate strongly typed interoperability. They provide great support at design time, where your experience of the interop is as good as if the types where really defined in .NET. However, at runtime these large assemblies can easily bloat your program, and also cause versioning issues because they are distributed independently of your application. The no-PIA feature allows you to continue to use PIAs at design time without having them around at runtime. Instead, the C# compiler will bake the small part of the PIA that a program actually uses directly into its assembly. At runtime the PIA does not have to be loaded. Omitting ref Because of a different programming model, many COM APIs contain a lot of reference parameters. Contrary to refs in C#, these are typically not meant to mutate a passed-in argument for the subsequent benefit of the caller, but are simply another way of passing value parameters. It therefore seems unreasonable that a C# programmer should have to create temporary variables for all such ref parameters and pass these by reference. Instead, specifically for COM methods, the C# compiler will allow you to pass arguments by value to such a method, and will automatically generate temporary variables to hold the passed-in values, subsequently discarding these when the call returns. In this way the caller sees value semantics, and will not experience any side effects, but the called method still gets a reference. Open issues A few COM interface features still are not surfaced in C#. Most notably these include indexed properties and default properties. As mentioned above these will be respected if you access COM dynamically, but statically typed C# code will still not recognize them. There are currently no plans to address these remaining speed bumps in C# 4.0. Variance An aspect of generics that often comes across as surprising is that the following is illegal: IList<string> strings = new List<string>(); IList<object> objects = strings; The second assignment is disallowed because strings does not have the same element type as objects. There is a perfectly good reason for this. If it were allowed you could write: objects[0] = 5; string s = strings[0]; Allowing an int to be inserted into a list of strings and subsequently extracted as a string. This would be a breach of type safety. However, there are certain interfaces where the above cannot occur, notably where there is no way to insert an object into the collection. Such an interface is IEnumerable<T>. If instead you say: IEnumerable<object> objects = strings; There is no way we can put the wrong kind of thing into strings through objects, because objects doesn’t have a method that takes an element in. Variance is about allowing assignments such as this in cases where it is safe. The result is that a lot of situations that were previously surprising now just work. Covariance In .NET 4.0 the IEnumerable<T> interface will be declared in the following way: public interface IEnumerable<out T> : IEnumerable { IEnumerator<T> GetEnumerator(); } public interface IEnumerator<out T> : IEnumerator { bool MoveNext(); T Current { get; } } The “out” in these declarations signifies that the T can only occur in output position in the interface – the compiler will complain otherwise. In return for this restriction, the interface becomes “covariant” in T, which means that an IEnumerable<A> is considered an IEnumerable<B> if A has a reference conversion to B. As a result, any sequence of strings is also e.g. a sequence of objects. This is useful e.g. in many LINQ methods. Using the declarations above: var result = strings.Union(objects); // succeeds with an IEnumerable<object> This would previously have been disallowed, and you would have had to to some cumbersome wrapping to get the two sequences to have the same element type. Contravariance Type parameters can also have an “in” modifier, restricting them to occur only in input positions. An example is IComparer<T>: public interface IComparer<in T> { public int Compare(T left, T right); } The somewhat baffling result is that an IComparer<object> can in fact be considered an IComparer<string>! It makes sense when you think about it: If a comparer can compare any two objects, it can certainly also compare two strings. This property is referred to as contravariance. A generic type can have both in and out modifiers on its type parameters, as is the case with the Func<…> delegate types: public delegate TResult Func<in TArg, out TResult>(TArg arg); Obviously the argument only ever comes in, and the result only ever comes out. Therefore a Func<object,string> can in fact be used as a Func<string,object>. Limitations Variant type parameters can only be declared on interfaces and delegate types, due to a restriction in the CLR. Variance only applies when there is a reference conversion between the type arguments. For instance, an IEnumerable<int> is not an IEnumerable<object> because the conversion from int to object is a boxing conversion, not a reference conversion. Also please note that the CTP does not contain the new versions of the .NET types mentioned above. In order to experiment with variance you have to declare your own variant interfaces and delegate types. COM Example Here is a larger Office automation example that shows many of the new C# features in action. using System; using System.Diagnostics; using System.Linq; using Excel = Microsoft.Office.Interop.Excel; using Word = Microsoft.Office.Interop.Word; class Program { static void Main(string[] args) { var excel = new Excel.Application(); excel.Visible = true; excel.Workbooks.Add(); // optional arguments omitted excel.Cells[1, 1].Value = "Process Name"; // no casts; Value dynamically excel.Cells[1, 2].Value = "Memory Usage"; // accessed var processes = Process.GetProcesses() .OrderByDescending(p =&gt; p.WorkingSet) .Take(10); int i = 2; foreach (var p in processes) { excel.Cells[i, 1].Value = p.ProcessName; // no casts excel.Cells[i, 2].Value = p.WorkingSet; // no casts i++; } Excel.Range range = excel.Cells[1, 1]; // no casts Excel.Chart chart = excel.ActiveWorkbook.Charts. Add(After: excel.ActiveSheet); // named and optional arguments chart.ChartWizard( Source: range.CurrentRegion, Title: "Memory Usage in " + Environment.MachineName); //named+optional chart.ChartStyle = 45; chart.CopyPicture(Excel.XlPictureAppearance.xlScreen, Excel.XlCopyPictureFormat.xlBitmap, Excel.XlPictureAppearance.xlScreen); var word = new Word.Application(); word.Visible = true; word.Documents.Add(); // optional arguments word.Selection.Paste(); } } The code is much more terse and readable than the C# 3.0 counterpart. Note especially how the Value property is accessed dynamically. This is actually an indexed property, i.e. a property that takes an argument; something which C# does not understand. However the argument is optional. Since the access is dynamic, it goes through the runtime COM binder which knows to substitute the default value and call the indexed property. Thus, dynamic COM allows you to avoid accesses to the puzzling Value2 property of Excel ranges. Relationship with Visual Basic A number of the features introduced to C# 4.0 already exist or will be introduced in some form or other in Visual Basic: · Late binding in VB is similar in many ways to dynamic lookup in C#, and can be expected to make more use of the DLR in the future, leading to further parity with C#. · Named and optional arguments have been part of Visual Basic for a long time, and the C# version of the feature is explicitly engineered with maximal VB interoperability in mind. · NoPIA and variance are both being introduced to VB and C# at the same time. VB in turn is adding a number of features that have hitherto been a mainstay of C#. As a result future versions of C# and VB will have much better feature parity, for the benefit of everyone. Resources All available resources concerning C# 4.0 can be accessed through the C# Dev Center. Specifically, this white paper and other resources can be found at the Code Gallery site.

  • PASS: Bylaw Changes

    - by Bill Graziano
    While you’re reading this, a post should be going up on the PASS blog on the plans to change our bylaws.  You should be able to find our old bylaws, our proposed bylaws and a red-lined version of the changes.  We plan to listen to feedback until March 31st.  At that point we’ll decide whether to vote on these changes or take other action. The executive summary is that we’re adding a restriction to prevent more than two people from the same company on the Board and eliminating the Board’s Officer Appointment Committee to have Officers directly elected by the Board.  This second change better matches how officer elections have been conducted in the past. The Gritty Details Our scope was to change bylaws to match how PASS actually works and tackle a limited set of issues.  Changing the bylaws is hard.  We’ve been working on these changes since the March board meeting last year.  At that meeting we met and talked through the issues we wanted to address.  In years past the Board has tried to come up with language and then we’ve discussed and negotiated to get to the result.  In March, we gave HQ guidance on what we wanted and asked them to come up with a starting point.  Hannes worked on building us an initial set of changes that we could work our way through.  Discussing changes like this over email is difficult wasn’t very productive.  We do a much better job on this at the in-person Board meetings.  Unfortunately there are only 2 or 3 of those a year. In August we met in Nashville and spent time discussing the changes.  That was also the day after we released the slate for the 2010 election. The discussion around that colored what we talked about in terms of these changes.  We talked very briefly at the Summit and again reviewed and revised the changes at the Board meeting in January.  This is the result of those changes and discussions. We made numerous small changes to clean up language and make wording more clear.  We also made two big changes. Director Employment Restrictions The first is that only two people from the same company can serve on the Board at the same time.  The actual language in section VI.3 reads: A maximum of two (2) Directors who are employed by, or who are joint owners or partners in, the same for-profit venture, company, organization, or other legal entity, may concurrently serve on the PASS Board of Directors at any time. The definition of “employed” is at the sole discretion of the Board. And what a mess this turns out to be in practice.  Our membership is a hodgepodge of interlocking relationships.  Let’s say three Board members get together and start a blog service for SQL Server bloggers.  It’s technically for-profit.  Let’s assume it makes $8 in the first year.  Does that trigger this clause?  (Technically yes.)  We had a horrible time trying to write language that covered everything.  All the sample bylaws that we found were just as vague as this. That led to the third clause in this section.  The first sentence reads: The Board of Directors reserves the right, strictly on a case-by-case basis, to overrule the requirements of Section VI.3 by majority decision for any single Director’s conflict of employment. We needed some way to handle the trivial issues and exercise some judgment.  It seems like a public vote is the best way.  This discloses the relationship and gets each Board member on record on the issue.   In practice I think this clause will rarely be used.  I think this entire section will only be invoked for actual employment issues and not for small side projects.  In either case we have the mechanisms in place to handle it in a public, transparent way. That’s the first and third clauses.  The second clause says that if your situation changes and you fall afoul of this restriction you need to notify the Board.  The clause further states that if this new job means a Board members violates the “two-per-company” rule the Board may request their resignation.  The Board can also  allow the person to continue serving with a majority vote.  I think this will also take some judgment.  Consider a person switching jobs that leads to three people from the same company.  I’m very likely to ask for someone to resign if all three are two weeks into a two year term.  I’m unlikely to ask anyone to resign if one is two weeks away from ending their term.  In either case, the decision will be a public vote that we can be held accountable for. One concern that was raised was whether this would affect someone choosing to accept a job.  I think that’s a choice for them to make.  PASS is clearly stating its intent that only two directors from any one organization should serve at any time.  Once these bylaws are approved, this policy should not come as a surprise to any potential or current Board members considering a job change.  This clause isn’t perfect.  The biggest hole is business relationships that aren’t defined above.  Let’s say that two employees from company “X” serve on the Board.  What happens if I accept a full-time consulting contract with that company?  Let’s assume I’m working directly for one of the two existing Board members.  That doesn’t violate section VI.3.  But I think it’s clearly the kind of relationship we’d like to prevent.  Unfortunately that was even harder to write than what we have now.  I fully expect that in the next revision of the bylaws we’ll address this.  It just didn’t make it into this one. Officer Elections The officer election process received a slightly different rewrite.  Our goal was to codify in the bylaws the actual process we used to elect the officers.  The officers are the President, Executive Vice-President (EVP) and Vice-President of Marketing.  The Immediate Past President (IPP) is also an officer but isn’t elected.  The IPP serves in that role for two years after completing their term as President.  We do that for continuity’s sake.  Some organizations have a President-elect that serves for one or two years.  The group that founded PASS chose to have an IPP. When I started on the Board, the Nominating Committee (NomCom) selected the slate for the at-large directors and the slate for the officers.  There was always one candidate for each officer position.  It wasn’t really an election so much as the NomCom decided who the next person would be for each officer position.  Behind the scenes the Board worked to select the best people for the role. In June 2009 that process was changed to bring it line with what actually happens.  An Officer Appointment Committee was created that was a subset of the Board.  That committee would take time to interview the candidates and present a slate to the Board for approval.  The majority vote of the Board would determine the officers for the next two years.  In practice the Board itself interviewed the candidates and conducted the elections.  That means it was time to change the bylaws again. Section VII.2 and VII.3 spell out the process used to select the officers.  We use the phrase “Officer Appointment” to separate it from the Director election but the end result is that the Board elects the officers.  Section VII.3 starts: Officers shall be appointed bi-annually by a majority of all the voting members of the Board of Directors. Everything else revolves around that sentence.  We use the word appoint but they truly are elected.  There are details in the bylaws for term limits, minimum requirements for President (1 prior term as an officer), tie breakers and filling vacancies. In practice we will have an election for President, then an election for EVP and then an election for VP Marketing.  That means that losing candidates will be able to fall down the ladder and run for the next open position.  Another point to note is that officers aren’t at-large directors.  That means if a current sitting officer loses all three elections they are off the Board.  Having Board member votes public will help with the transparency of this approach. This process has a number of positive and negatives.  The biggest concern I expect to hear is that our members don’t directly choose the officers.  I’m going to try and list all the positives and negatives of this approach. Many non-profits value continuity and are slower to change than a business.  On the plus side this promotes that.  On the negative side this promotes that.  If we change too slowly the members complain that we aren’t responsive.  If we change too quickly we make mistakes and fail at various things.  We’ve been criticized for both of those lately so I’m not entirely sure where to draw the line.  My rough assumption to this point is that we’re going too slow on governance and too quickly on becoming “more than a Summit.”  This approach creates competition in the officer elections.  If you are an at-large director there is no consequence to losing an election.  If you are an officer the only way to stay on the Board is to win an officer election or an at-large election.  If you are an officer and lose an election you can always run for the next office down.  This makes it very easy for multiple people to contest an election. There is value in a person moving through the officer positions up to the Presidency.  Having the Board select the officers promotes this.  The down side is that it takes a LOT of time to get to the Presidency.  We’ve had good people struggle with burnout.  We’ve had lots of discussion around this.  The process as we’ve described it here makes it possible for someone to move quickly through the ranks but doesn’t prevent people from working their way up through each role. We talked long and hard about having the officers elected by the members.  We had a self-imposed deadline to complete these changes prior to elections this summer. The other challenge was that our original goal was to make the bylaws reflect our actual process rather than create a new one.  I believe we accomplished this goal. We ran out of time to consider this option in the detail it needs.  Having member elections for officers needs a number of problems solved.  We would need a way for candidates to fall through the election.  This is what promotes competition.  Without this few people would risk an election and we’ll be back to one candidate per slot.  We need to do this without having multiple elections.  We may be able to copy what other organizations are doing but I was surprised at how little I could find on other organizations.  We also need a way for people that lose an officer election to win an at-large election.  Otherwise we’ll have very little competition for officers. This brings me to an area that I think we as a Board haven’t done a good job.  We haven’t built a strong process to tell you who is doing a good job and who isn’t.  This is a double-edged sword.  I don’t want to highlight Board members that are failing.  That’s not a good way to get people to volunteer and run for the Board.  But I also need a way let the members make an informed choice about who is doing a good job and would make a good officer.  Encouraging Board members to blog, publishing minutes and making votes public helps in that regard but isn’t the final answer.  I don’t know what the final answer is yet.  I do know that the Board members themselves are uniquely positioned to know which other Board members are doing good work.  They know who speaks up in meetings, who works to build consensus, who has good ideas and who works with the members.  What I Could Do Better I’ve learned a lot writing this about how we communicated with our members.  The next time we revise the bylaws I’d do a few things differently.  The biggest change would be to provide better documentation.  The March 2009 minutes provide a very detailed look into what changes we wanted to make to the bylaws.  Looking back, I’m a little surprised at how closely they matched our final changes and covered the various arguments.  If you just read those you’d get 90% of what we eventually changed.  Nearly everything else was just details around implementation.  I’d also consider publishing a scope document defining exactly what we were doing any why.  I think it really helped that we had a limited, defined goal in mind.  I don’t think we did a good job communicating that goal outside the meeting minutes though. That said, I wish I’d blogged more after the August and January meeting.  I think it would have helped more people to know that this change was coming and to be ready for it. Conclusion These changes address two big concerns that the Board had.  First, it prevents a single organization from dominating the Board.  Second, it codifies and clearly spells out how officers are elected.  This is the process that was previously followed but it was somewhat murky.  These changes bring clarity to this and clearly explain the process the Board will follow. We’re going to listen to feedback until March 31st.  At that time we’ll decide whether to approve these changes.  I’m also assuming that we’ll start another round of changes in the next year or two.  Are there other issues in the bylaws that we should tackle in the future?

  • Users loggin to 3Com switches authenticated by radius not getting admin priv and no access available

    - by 3D1L
    Hi, Following the setup that I have for my Cisco devices, I got some basic level of functionality authenticating users that loggin to 3Com switches authenticated against a RADIUS server. Problem is that I can not get the user to obtain admin privileges. I'm using Microsoft's IAS service. According to 3Com documentation when configuring the access policy on IAS the value of 010600000003 have to be used to specify admin access level. That value have to be input in the Dial-in profile section: 010600000003 - indicates admin privileges 010600000002 - manager 010600000001 - monitor 010600000000 - visitor Here is the configuration on the switch: radius scheme system server-type standard primary authentication XXX.XXX.XXX.XXX accounting optional key authentication XXXXXX key accounting XXXXXX domain system scheme radius-scheme system local-user admin service-type ssh telnet terminal level 3 local-user manager service-type ssh telnet terminal level 2 local-user monitor service-type ssh telnet terminal level 1 The configuration is working with the IAS server because I can check user login events with the Eventviewer tool.

  • Executing legacy MSBuild scripts in TFS 2010 Build

    - by Jakob Ehn
    When upgrading from TFS 2008 to TFS 2010, all builds are “upgraded” in the sense that a build definition with the same name is created, and it uses the UpgradeTemplate  build process template to execute the build. This template basically just runs MSBuild on the existing TFSBuild.proj file. The build definition contains a property called ConfigurationFolderPath that points to the TFSBuild.proj file. So, existing builds will run just fine after upgrade. But what if you want to use the new workflow functionality in TFS 2010 Build, but still have a lot of MSBuild scripts that maybe call custom MSBuild tasks that you don’t have the time to rewrite? Then one option is to keep these MSBuild scrips and call them from a TFS 2010 Build workflow. This can be done using the MSBuild workflow activity that is avaiable in the toolbox in the Team Foundation Build Activities section: This activity wraps the call to MSBuild.exe and has the following parameters: Most of these properties are only relevant when actually compiling projects, for example C# project files. When calling custom MSBuild project files, you should focus on these properties: Property Meaning Example CommandLineArguments Use this to send in/override MSBuild properties in your project “/p:MyProperty=SomeValue” or MSBuildArguments (this will let you define the arguments in the build definition or when queuing the build) LogFile Name of the log file where MSbuild will log the output “MyBuild.log” LogFileDropLocation Location of the log file BuildDetail.DropLocation + “\log” Project The project to execute SourcesDirectory + “\BuildExtensions.targets” ResponseFile The name of the MSBuild response file SourcesDirectory + “\BuildExtensions.rsp” Targets The target(s) to execute New String() {“Target1”, “Target2”} Verbosity Logging verbosity Microsoft.TeamFoundation.Build.Workflow.BuildVerbosity.Normal Integrating with Team Build   If your MSBuild scripts tries to use Team Build tasks, they will most likely fail with the above approach. For example, the following MSBuild project file tries to add a build step using the BuildStep task:   <?xml version="1.0" encoding="utf-8"?> <Project ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003"> <Import Project="$(MSBuildExtensionsPath)\Microsoft\VisualStudio\TeamBuild\Microsoft.TeamFoundation.Build.targets" /> <Target Name="MyTarget"> <BuildStep TeamFoundationServerUrl="$(TeamFoundationServerUrl)" BuildUri="$(BuildUri)" Name="MyBuildStep" Message="My build step executed" Status="Succeeded"></BuildStep> </Target> </Project> When executing this file using the MSBuild activity, calling the MyTarget, it will fail with the following message: The "Microsoft.TeamFoundation.Build.Tasks.BuildStep" task could not be loaded from the assembly \PrivateAssemblies\Microsoft.TeamFoundation.Build.ProcessComponents.dll. Could not load file or assembly 'file:///D:\PrivateAssemblies\Microsoft.TeamFoundation.Build.ProcessComponents.dll' or one of its dependencies. The system cannot find the file specified. Confirm that the <UsingTask> declaration is correct, that the assembly and all its dependencies are available, and that the task contains a public class that implements Microsoft.Build.Framework.ITask. You can see that the path to the ProcessComponents.dll is incomplete. This is because in the Microsoft.TeamFoundation.Build.targets file the task is referenced using the $(TeamBuildRegPath) property. Also note that the task needs the TeamFounationServerUrl and BuildUri properties. One solution here is to pass these properties in using the Command Line Arguments parameter:   Here we pass in the parameters with the corresponding values from the curent build. The build log shows that the build step has in fact been inserted:   The problem as you probably spted is that the build step is insert at the top of the build log, instead of next to the MSBuild activity call. This is because we are using a legacy team build task (BuildStep), and that is how these are handled in TFS 2010. You can see the same behaviour when running builds that are using the UpgradeTemplate, that cutom build steps shows up at the top of the build log.

  • What is Agile Modeling and why do I need it?

    What is Agile Modeling and why do I need it? Agile Modeling is an add-on to existing agile methodologies like Extreme programming (XP) and Rational Unified Process (RUP). Agile Modeling enables developers to develop a customized software development process that actually meets their current development needs and is flexible enough to adjust in the future. According to Scott Ambler, Agile Modeling consists of five core values that enable this methodology to be effective and light weight Agile Modeling Core Values: Communication Simplicity Feedback Courage Humility Communication is a key component to any successful project. Open communication between stakeholder and the development team is essential when developing new applications or maintaining legacy systems. Agile models promote communication amongst software development teams and stakeholders. Furthermore, Agile Models provide a common understanding of an application for members of a software development team allowing them to have a universal common point of reference. The use of simplicity in Agile Models enables the exploration of new ideas and concepts through the use of basic diagrams instead of investing the time in writing tens or hundreds of lines of code. Feedback in regards to application development is essential. Feedback allows a development team to confirm that the development path is on track. Agile Models allow for quick feedback from shareholders because minimal to no technical expertise is required to understand basic models. Courage is important because you need to make important decisions and be able to change direction by either discarding or refactoring your work when some of your decisions prove inadequate, according to Scott Ambler. As a member of a development team, we must admit that we do not know everything even though some of us think we do. This is where humility comes in to play. Everyone is a knowledge expert in their own specific domain. If you need help with your finances then you would consult an accountant. If you have a problem or are in need of help with a topic why would someone not consult with a subject expert? An effective approach is to assume that everyone involved with your project has equal value and therefore should be treated with respect. Agile Model Characteristics: Purposeful Understandable Sufficiently Accurate Sufficiently Consistent Sufficiently Detailed Provide Positive Value Simple as Possible Just Fulfill Basic Requirements According to Scott Ambler, Agile models are the most effective possible because the time that is invested in the model is just enough effort to complete the job. Furthermore, if a model isn’t good enough yet then additional effort can be invested to get more value out of the model. However if a model is good enough, for the current needs, or surpass the current needs, then any additional work done on the model would be a waste. It is important to remember that good enough is in the eye of the beholder, so this can be tough. In order for Agile Models to work effectively Active Stakeholder need to participation in the modeling process. Finally it is also very important to model with others, this allows for additionally input ensuring that all the shareholders needs are reflected in the models. How can Agile Models be incorporated in to our projects? Agile Models can be incorporated in to our project during the requirement gathering and design phases. As requirements are gathered the models should be updated to incorporate the new project details as they are defined and updated. Additionally, the Agile Models created during the requirement phase can be the bases for the models created during the design phase.  It is important to only add to the model when the changes fit within the agile model characteristics and they do not over complicate the design.

I'd like to introduce a new member of the Oracle WebCenter Team, Christian Finn. We decided to let him do his own intros today. Look for his guest posts next week and he'll be a frequent contributor to WebCenter blog and voice of the community. Hello (Oracle) World! Hi everyone, my name is Christian Finn. It’s a coder’s tradition to have “hello world” be the first output from a new program or in a new language. While I have left my coding days far behind, it still seems fitting to start my new role here at Oracle by saying hello to all of you—our customers, partners and my colleagues. So by way of introduction, a little background about me. I am the new senior director for evangelism on the WebCenter product management team. Not only am I new to Oracle, but the evangelism team is also brand new. Our mission is to raise the profile of Oracle in all of the markets/conversations in which WebCenter competes—social business, collaboration, portals, Internet sites, and customer/audience engagement. This is all pretty familiar turf for me because, as some of you may know, until recently I was the director of product management at Microsoft for Microsoft SharePoint Server and several other SharePoint products. And prior to that, I held management roles at Microsoft in marketing, channels, learning, and enterprise sales. Before Microsoft, I got my start in the industry as a software trainer and Lotus Notes consultant. I am incredibly excited to be joining Oracle at this time because of the tremendous opportunity that lies ahead to improve how people and businesses work. Of all the vendors offering a vision for social business, Oracle is unique in having best of breed strength in market (or coming soon) in all three critical areas: customer experience management; the middleware and back-end applications that run your business; and in the social, collaboration, and content technologies that are the connective tissue between them. Everyone else can offer one or two of the above, but not all three unified together. So it is a great time to come board and there’s a fantastic team of people hard at work on building great products for you. In the coming weeks and months you’ll be hearing much more from us. For now, we’ll kick things off with some blog posts here on the WebCenter blog. Enjoy the reads and please share your thoughts with me over Twitter on @cfinn.

  • Agile Manifesto, Revisited

    - by GeekAgilistMercenary
    Again, conversations give me a zillion things to write about.  The recent conversation that has cropped up again is my various viewpoints of the Agile Manifesto.  Not all the processes that came after the manifesto was written, but just the core manifesto itself.  Just for context, here is the manifesto in all the glory. We are uncovering better ways of developing software by doing it and helping others do it. Through this work we have come to value: Individuals and interactions over processes and tools Working software over comprehensive documentation Customer collaboration over contract negotiation Responding to change over following a plan That is, while there is value in the items on the right, we value the items on the left more. Several of the key signatories at the time went on to write some of the core books that really gave Agile Software Development traction.  If you check out the Agile Manifesto Site and do a search for any of those people, you will find a treasure trove of software development information. My 2 Cents First off, I agree with a few people out there.  Agile is not Scrum for instance.  Do NOT get these things confused when checking out Agile, or pushing forward with Scrum.  As David Starr points out in his blog entry, "About 35 minutes into this discussion, I realized I hadn?t heard a question or comment that wasn?t related to Scrum. I asked the room, ?How many people are on an agile team that is NOT using Scrum?? 5 hands. Seriously, out of about 150 people of so. 5 hands." So know, as this is one of my biggest pet peves these days, that Scrum is not Agile.  Another quote David writes, "I assure you, dear reader, 2 week time boxes does not an agile team make." This is the exact problem.  Take a look at the actual manifesto above.  First ideal, "Individuals and interactions over processes and tools".  There are a couple of meanings in this ideal, just as there are in the other written ideals.  But this one has a lot of contention with a set practice such as Scrum.  There are other formulas, namely XP (eXtreme) and Kanban are two that come to mind often.  But none of these are Agile, but instead a process based on the ideals of Agile. Some of you may be thinking, "that?s the same thing".  Well, no, it is not.  This type of differentiation is vitally important.  Agile is a set of ideals.  Processes are nice, but they can change, they may work for some and not others.  The Agile Manifesto covers the ideals behind what is intended, that intention being to learn and find new ways to build better software. Ideals, not processes.  Definition versus implementation.  Class versus object.  The ideals are of utmost importance, the processes are secondary, the first ideal is what really lays this out for me "Individuals and interactions over processes and tools".  Yes, we need tools but we need the individuals and their interactions more. For those coming into a development team, I hope you take this to mind.  It is of utmost importance that this differentiation is known and fought for.  The second the process becomes more important than the individuals and interactions, the team will effectively lose the advantages of Agile Ideals. This is just one of my first thoughts on the topic of Agile.  I will be writing more in the near future about each of the ideals.  I will make a point to outline more of my thoughts, my opinions, and experience with the ideals of Agile and the various processes that are out there.  Maybe, I may stumble upon something new with the help of my readers?  It would be a grand overture to the ideals I hold. For the original entry, check out my personal blog with other juicy tech tidbits, rants, raves, and the like. Agilist Mercenary

    The Top 10 most-clicked items shared on the OTN ArchBeat Facebook page for the week of December 2-8, 2012 Configure Oracle SOA JMSAdatper to Work with WLS JMS Topics Another of the four posts published on Dec 4 by the Fusion Middleware A-Team blogger identified as "fip" illlustrates "how to configure the JMS Topic, the JmsAdapter connection factory, as well as the composite so that the JMS Topic messages will be evenly distributed to same composite running off different SOA cluster nodes without causing duplication." Web Service Example - Part 3: Asynchronous Part 3 in this series from the Oracle ADF Mobile blog looks at "firing the web service asynchronously and then filling in the UI when it completes." Denis says, "This can be useful when you have data on the device in a local store and want to show that to the user while the application uses lazy loading from a web service to load more data." Advanced Oracle SOA Suite Oracle Open World 2012 SOA Presentations Oracle SOA & BPM Partner Community blogger Juergen Kress shares a list of 13 SOA presentations delivered or moderated by Oracle SOA Product Management at OOW12 in San Francisco. Oracle WebLogic Server WLS Domain Browser My colleague Jeff Davies, a frequent speaker at OTN Architect Day events and a genuinely nice guy, emailed me last night with this message: "I just came across this app on Google Play. It allows WebLogic administrators to browse WLS 12c domain information. I installed it on my phone and tried it out. Works very fast." I'm an iPhone guy, but I'm perfectly comfortable taking Jeff at his word. The app is called WLS Domain Browser. Follow the link for more info from the Google Play site. Retrieve Performance Data from SOA Infrastructure Database Another of the four blog posts published on Dec 4 by very busy Oracle Fusion Middleware A-Team member "fip," this one offers "examples of some basic SQL queries you can run against the infrastructure database of Oracle SOA Suite 11G to acquire the performance statistics for a given period of time." How to Achieve OC4J RMI Load Balancing "Having returned from a customer who faced challenges with OC4J RMI load balancing, I felt there is still some confusion in the field [about] how OC4J RMI load balancing works," says the Oracle Fusion Middleware A-Team member known only as "fip." "Hence I decide to dust off an old tech note that I wrote a few years back and share it with the general public." From XaaS to Java EE – Which damn cloud is right for me in 2012? Oracle ACE Director Markus Eisele wrestles with a timely technical issue and shares his observations on several of the alternatives. Exalogic 2.0.1 Tea Break Snippets - Creating a ModifyJeOS VirtualBox "One of the main advantages of this is that Templates can be created away from the Exalogic Environment," explains The Old Toxophilist. (BTW: I had to look it up: a toxophilist is one who collects bows and arrows.) ADF Mobile - Implementing Reusable Mobile Architecture "Reusability was always a strong part of ADF," says Oracle ACE Director Andrejus Baranovskis. "The same high reusability level is supported now in ADF Mobile." The objective of this post is "to prove technically that [the] reusable architecture concept works for ADF Mobile." Using BPEL Performance Statistics to Diagnose Performance Bottlenecks Someone had a busy day… This post, one of four published on DeC 4 by a member of the Oracle Fusion Middleware A-Team identified only as "fip," offers details on how to "enable, retrieve and interpret the performance statistics, before the future versions provides a more pleasant user experience." Thought for the Day "If you're afraid to change something it is clearly poorly designed." — Martin Fowler Source: SoftwareQuotes.com

  • Python Coding standards vs. productivity

    - by Shroatmeister
    I work for a large humanitarian organisation, on a project building software that could help save lives in emergencies by speeding up the distribution of food. Many NGOs desperately need our software and we are weeks behind schedule. One thing that worries me in this project is what I think is an excessive focus on coding standards. We write in python/django and use a version of PEP0008, with various modifications e.g. line lengths can go up to 160 chars and all lines should go that long if possible, no blank lines between imports, line wrapping rules that apply only to certain kinds of classes, lots of templates that we must use, even if they aren't the best way to solve a problem etc. etc. One core dev spent a week rewriting a major part of the system to meet the then new coding standards, throwing away several suites of tests in the process, as the rewrite meant they were 'invalid'. We spent two weeks rewriting all the functionality that was lost, and fixing bugs. He is the lead dev and his word carries weight, so he has convinced the project manager that these standards are necessary. The junior devs do as they are told. I sense that the project manager has a strong feeling of cognitive dissonance about all this but nevertheless agrees with it vehemently as he feels unsure what else to do. Today I got in serious trouble because I had forgotten to put some spaces after commas in a keyword argument. I was literally shouted at by two other devs and the project manager during a Skype call. Personally I think coding standards are important but also think that we are wasting a lot of time obsessing with them, and when I verbalized this it provoked rage. I'm seen as a troublemaker in the team, a team that is looking for scapegoats for its failings. Since the introduction of the coding standards, the team's productivity has measurably plummeted, however this only reinforces the obsession, i.e. the lead dev simply blames our non-adherence to standards for the lack of progress. He believes that we can't read each other's code if we don't adhere to the conventions. This is starting to turn sticky. Now I am trying to modify various scripts, autopep8, pep8ify and PythonTidy to try to match the conventions. We also run pep8 against source code but there are so many implicit amendments to our standard that it's hard to track them all. The lead dev simple picks faults that the pep8 script doesn't pick up and shouts at us in the next stand-up meeting. Every week there are new additions to the coding standards that force us to rewrite existing, working, tested code. Thank heavens we still have tests, (I reverted some commits and fixed a bunch of the ones he removed). All the while there is increasing pressure to meet the deadline. I believe a fundamental issue is that the lead dev and another core dev refuse to trust other developers to do their job. But how to deal with that? We can't do our job because we are too busy rewriting everything. I've never encountered this dynamic in a software engineering team. Am I wrong to question their adherence to coding standards? Has anyone else experienced a similar situation and how have they dealt with it successfully? (I'm not looking for a discussion just actual solutions people have found)

  • My Experience at Oracle !!! By Ayush Gupta

    - by Nadiya
    Normal 0 false false false EN-US X-NONE X-NONE Hi! My name is Ayush, a Gratuate from BITS Pilani and now working and living in Bangalore. I joined Oracle in August 2013 as a Senior Consultant (SC) and would like to share my experiences over the first couple of months with you.It has been a wonderful journey so far. The last two months have been very exciting for me. First of all I would like to mention that the training program at Oracle that we went through really prepared us well. It matured us and allowed us to go from developing small applications in college to big enterprise products. Two months of initial training has had a lasting impact for me. I am also really enjoying the knowledge I have gained so far and also learning new things in the form of product training. It's really fun to work here. We are treated like adults and we are responsible for our own workloads.With that I can't keep from mentioning the fun times we as a team have in the form of Young Leadership programme in Hotel Fortune Trinity which included Luxurious buffet lunch too. Wishing it could happen more frequently.  Oracle provides one of the best opportunities to learn various technologies across different platforms. What I like best about working at Oracle is the work life balance. With the option of flexible timings, one can easily enjoy planned evenings with friends or maybe working out at the fitness centre in your building. Be it the birthday celebrations at office or the day long team outing at a resort, It’s all together a different experience. Overall, you get to take full ownership of your project and they give you a free leash on how you design your enhancements/changes.As one of the largest international companies, Oracle is obviously an expert on exploring the potential and possibility of inexperienced new hires. We were taught how to make an outstanding team work in a group training session at the first few weeks. From this experience I realized that perfect cooperation is not about where you come from or what your study background is, everyone can find his or her own role to support the team. Even though I am not that skilled in technology, my background has significantly helped me in learning new technologies in Oracle.My idea and suggestion is: for new joiners, the will to learn is be more important than what you have learnt before. Colleagues here at Oracle are professionals in their field, always friendly and glad to help. So don’t worry, all you need to do is just be confident, and have a nice attitude, Oracle will let you fully display your talent. Come and join us, here you can always find a tailor made role for you! /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin-top:0in; mso-para-margin-right:0in; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0in; line-height:115%; mso-pagination:widow-orphan; font-family:"Calibri","sans-serif"; mso-ascii- mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi- mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;}

  • Sweet and Sour Source Control

    - by Tony Davis
    Most database developers don't use Source Control. A recent anonymous poll on SQL Server Central asked its readers "Which Version Control system do you currently use to store you database scripts?" The winner, with almost 30% of the vote was...none: "We don't use source control for database scripts". In second place with almost 28% of the vote was Microsoft's VSS. VSS? Given its reputation for being buggy, unstable and lacking most of the basic features required of a proper source control system, answering VSS is really just another way of saying "I don't use Source Control". At first glance, it's a surprising thought. You wonder how database developers can work in a team and find out what changed, when the system worked before but is now broken; to work out what happened to their changes that now seem to have vanished; to roll-back a mistake quickly so that the rest of the team have a functioning build; to find instantly whether a suspect change has been deployed to production. Unfortunately, the survey didn't ask about the scale of the database development, and correlate the two questions. If there is only one database developer within a schema, who has an automated approach to regular generation of build scripts, then the need for a formal source control system is questionable. After all, a database stores far more about its metadata than a traditional compiled application. However, what is meat for a small development is poison for a team-based development. Here, we need a form of Source Control that can reconcile simultaneous changes, store the history of changes, derive versions and builds and that can cope with forks and merges. The problem comes when one borrows a solution that was designed for conventional programming. A database is not thought of as a "file", but a vast, interdependent and intricate matrix of tables, indexes, constraints, triggers, enumerations, static data and so on, all subtly interconnected. It is an awkward fit. Subversion with its support for merges and forks, and the tolerance of different work practices, can be made to work well, if used carefully. It has a standards-based architecture that allows it to be used on all platforms such as Windows Mac, and Linux. In the words of Erland Sommerskog, developers should "just do it". What's in a database is akin to a "binary file", and the developer must work only from the file. You check out the file, edit it, and save it to disk to compile it. Dependencies are validated at this point and if you've broken anything (e.g. you renamed a column and broke all the objects that reference the column), you'll find out about it right away, and you'll be forced to fix it. Nevertheless, for many this is an alien way of working with SQL Server. Subversion is the powerhouse, not the GUI. It doesn't work seamlessly with your existing IDE, and that usually means SSMS. So the question then becomes more subtle. Would developers be less reluctant to use a fully-featured source (revision) control system for a team database development if they had a turn-key, reliable system that fitted in with their existing work-practices? I'd love to hear what you think. Cheers, Tony.
