DevOps is a term I’m hearing more and more during customer conversation, and I am often sharing the different ways that Delphi, C++Builder and RAD Studio programming supports DevOps. (Keep reading – free infographic below) The term DevOps originates back to around 2008/9 when the two worlds of Development and Operations were traditionally stereotypes as Dev V Ops, with typical exchanges like “It’s not my machines, it’s your code!” – “No, it’s not my code it’s your machines!”. These stereotypes were built from friction found in the key business requirement for almost any system – making changes! The ability to rapidly make changes is important if you want to stay ahead of the competition. RAD developers are used to Agile development and being able to create changes quickly, however, getting them deployed needs Operations. To the Operations team, making changes brings a high-risk of an outage, but this prevents innovations from being pushed in a timely manner. This conflict is something that DevOps acknowledges and tries to breakdown through new ways of working that bring both sides closer together. Over the years, the two worlds of Dev and Ops have had to start thinking more like each other, including, how to get feedback from live environments to find issues that appear in the code. Agile, and DevOps like to re-use and expand, so rather than giving a full-blown commentary on how RAD Studio supports Delphi and C++ Builder developers today, let me keep it simple and say that the libraries, components, toolchains (and more) found in RAD Studio, and our wider partner ecosystem, provide broad support to both Developers and Operations teams who need to communicate and share what is happening in the field. The component-based architecture and cross-platform libraries that work across multiple systems are the perfect foundation stone for rapid agile development, that can be supported simply. But finally, a picture paints a thousand words. This is just a snapshot of the RAD eco-system, there is too much to put everything on here, but I hope this gives a flavor of just the tip of the iceberg, and how the RAD Studio IDE, and the Delphi and C++Builder languages and libraries are enabling development teams the world over to support DevOps today.

Animation, Effects and Transition are the words applied mostly to the Film Industry and those days were gone. But these become the basic expectation from the customer for any Mobile, Desktop, Web Applications. A simple meme requires animations to convey a message more creatively. Will you miss to provide such a feature in your Delphi/C++ Application to wow your customers? This post will provide a quick overview of animation, Image Effects, Transition, and Direct how to do the same in FireMonkey Applications. Animation: Animations modify property values over time. They can be started automatically or manually, both with an optional delay. After the animation has run its course over the defined time period, it can stop, start over, or do the same but in reverse. Kinds of Animation : The provided subclasses of TAnimation fall into three categories: Interpolations from a start value to an end value: TIntAnimation changes any property that is an integer. TFloatAnimation changes any property that is a real number, like position (X, Y, and Z axes must be done separately), rotation, and opacity. TRectAnimation changes the location of the four edges of a TBounds property. TColorAnimation changes any string or integer property that contains a color, including those of type TAlphaColor (which is actually a Cardinal number), by modifying the red, green, blue, and alpha values of the color. TGradientAnimation changes a gradient (type TGradient) by modifying the colors of each point that defines the gradient. TBitmapAnimation transitions from a starting bitmap image to another by drawing the final image (type TBitmap) with increasing opacity, causing it to fade into view. Interpolating through a series of values, not just two: from the first to the second, from the second to the third, and so on: Stepping through a list without interpolation: TBitmapListAnimation works like a timed slideshow, with all images combined horizontally into a single bitmap. With a fast frame rate (short duration and/or many images), it looks like a movie. Animation Type Controls how Interpolations is applied(Start and End). Image Effects: The FireMonkey built-in ImageFX engine provides over 50 GPU-powered effects. These effects are nonvisual components that can be found in the Effects category on the Tool Palette. All the provided effects can be simply enabled or disabled by setting the Enabled flag from the Form Designer, or programmatically. To know More about the Kinds of effects Check here Transition Effects: FireMonkey includes over twenty image transition effects, in which source pixels are progressively transformed into a target bitmap image, from simple fades to fancy banded swirls. The progress of the transformation is deterministic and can be set to an arbitrary percentage. This percentage can be animated to transition over time. To animate the progress of the transformation, see Apply an Animation Effect to a Property of an Image Effect. I guess, You might got rough idea on Animation, Effects, Transition Effects. Watch this Video, Delphi Skill Sprint – Using Effects, Animations and Transitions on FireMonkey shown below for Demonstration. Check this video for more demonstration on the same topic which covers FMX TTabControl Transitions as well.

A Module is a file containing Python definitions and statements similar to the unit file in Delphi. To learn more about Python modules check this tutorial. How to create such Python Modules in Delphi using Python4Delphi components? This post will guide you. You can also use Python4Delphi with C++Builder. Python4Delphi Demo5 Sample App shows how to create a Module, add a routine to that module, Import the module in a python script, and access the added routine. You can find the Demo5 source on GitHub. Prerequisites: Download and install the latest Python for your platform. Follow the Python4Delphi installation instructions mentioned here. Alternatively, you can check out this video Getting started with Python4Delphi. Components used in Python4Delphi Demo5 App: TPythonEngine: A collection of relatively low-level routines for communicating with Python, creating Python types in Delphi, etc. It’s a singleton class. TPythonGUIInputOutput: Inherited from TPythonInputOutput (which works as a console for python outputs) Using this component Output property you can associate the Memo component to show the Output. TPythonModule: It’s inherited from TMethodsContainer class allows creating modules by providing a name. You can use routines AddMethod, AddMethodWithKW to add a method of type PyCFunction. You can create events using the Events property. TMemo: A multiline text editing control, providing text scrolling. The text in the memo control can be edited as a whole or line by line. You can find the Python4Delphi Demo5 sample project from the extracted GitHub repository ..Python4DelphiDemosDemo05.dproj. Open this project in RAD Studio 10.4.1 and run the application. Implementation Details: PythonEngine1 component provides the connection to Python or rather the Python API. This project uses Python3.9 which can be seen in TPythonEngine DllName property. It Is assigned with InitScript which import sys module and prints the Python.Dll version, copyright information to Memo2 using this InitScript. import sys print(“Python Dll: “, sys.version) print(sys.copyright) print() PythonGUIInputOutput1 component provides a conduit for routing input and output between the Graphical User Interface (GUI) and the currentlyexecuting Python script. PythonModule1 with Module name spam is created. During PythonModule1Initialization a method spam_foo is added to the Module. And the definition of the method is included in the same unit file. Logically a python module is created and its methods were created using this PythonModule. Later this can be imported into your python script wherever necessary. function spam_foo( self, args : PPyObject ) : PPyObject; cdecl; begin with GetPythonEngine do begin ShowMessage( ‘args of foo: ‘+PyObjectAsString(args) ); Result := ReturnNone; end; end; procedure TForm1.PythonModule1Initialization(Sender: TObject); begin with Sender as TPythonModule do begin AddMethod( ‘foo’, spam_foo, ‘foo’ ); end; end; function spam_foo( self, args : PPyObject ) : PPyObject; cdecl; begin   with GetPythonEngine do     begin       ShowMessage( ‘args of foo: ‘+PyObjectAsString(args) );       Result := ReturnNone;     end; end; procedure TForm1.PythonModule1Initialization(Sender: TObject); begin   with Sender as TPythonModule do     begin       AddMethod( ‘foo’, spam_foo, ‘foo’ );     end; end; Memo1, used for providing the Python Script which imports spam (PythonModule1), accesses the method spam.foo and the method shows the output. Buttons to perform the execution, load script from, and save the script to file. On Clicking Execute Script Button the script import spam print (spam.foo(‘hello world’, 1)) is executed.

C++ is getting many new features and improved code hygiene, which improves your code compile time. In this webinar, you can watch and listen to the conversation with Bjarne Stroustrup and David Intersimone.  Overview C++17 Current Standard C++20 According to Bjarne Stroustrup, C++ is not a simple language, but you can write code simply and that compiles faster once it is done.  Bjarne Stroustrup has written a paper in 1981 saying you need generic programming, and he conjectured that macros was the way to get it. Actually, he was right about the problem. Now, today it has been solved.  C++ Core Guidelines The most interesting view in this session is that Bjarne Stroustrup, saying you can not just simplify the programming language: C++. People want more simple stuff and they say add this and that features and do not break my code. So, the better way is to have good coding guidelines, better teaching, tool support like the static analysis. Be sure to watch the session to learn more about C++ history and its near future!

BCC32, which is the classic C++Builder 32 bit compiler, includes the use of rvalue references, which allow creating a reference to temporaries. Also, rvalue references avoid unnecessary copying and make possible perfect forwarding functions. This feature is one of the C++11 features. Rvalue references are a compound type like standard C++ references, which are referred to as lvalue references. An lvalue reference is formed by appending the ampersand character (&) to a type: SomeClass l; SomeClass& lReference = l; //lvalue reference SomeClass l; SomeClass& lReference = l;    //lvalue reference The syntax of an rvalue reference is to add && after a type: SomeClass r; SomeClass&& rReference = r; //rvalue reference  SomeClass r; SomeClass&& rReference = r;    //rvalue reference  An rvalue reference behaves like an lvalue reference, except that you can bind an rvalue reference to a temporary — an rvalue. SomeClass a; a = SomeClass(); SomeClass& lReference = a; //OK-lvalue reference can bind to an lvalue such as “a” SomeClass& lReference2 = SomeClass(); //error-lvalue reference can’t bind to an rvalue SomeClass&& rReference = SomeClass(); //OK for rvalue reference to bind to rvalue // Both references can be used the same way SomeOtherClass value1 = SomeFunc(lReference); SomeOtherClass value2 = SomeFunc(rReference); SomeClass a; a = SomeClass(); SomeClass& lReference = a;         //OK-lvalue reference can bind to an lvalue such as “a” SomeClass& lReference2 = SomeClass();  //error-lvalue reference can’t bind to an rvalue SomeClass&& rReference = SomeClass();  //OK for rvalue reference to bind to rvalue   // Both references can be used the same way SomeOtherClass value1 = SomeFunc(lReference); SomeOtherClass value2 = SomeFunc(rReference); In the example above, SomeClass() is not bound to an identifier, so it is an rvalue and can be bound to an rvalue reference — but not an lvalue reference. Here is the above sample code in C++Builder. Find out more about C++ rvalue References over in the Embarcadero DocWiki.
