Delphi Language Progression Suggestions

Delphi Language Progression Suggestions

Since ~Delphi 2010, we have had generics, attributes, iterators, and some other compiler niceties. While many of the features we would like are difficult to implement, I believe that a few simple language features are long overdue.

Dropping a DOM node without consulting its parent

Dropping a DOM node without consulting its parent

For quite a long time, it was pretty cumbersome to delete a node from the DOM of an HTML document because one had to go to its parent and ask it to destroy its child (by invoking removeChild), like so:

Introduction to C# on ReactOS

Introduction to C# on ReactOS

ReactOS is an open source alternative to the Windows operation system. Even if the first version of ReactOS dates back to 1998, there is still no ‘stable’ version of ReactOS. May be, the most important reason is a lack of attention.

Scaffolding Dapper with CatFactory

Scaffolding Dapper with CatFactory

Dapper is an ORM for .NET and .NET Core, to develop large applications it’s very hard to write code for a lot of objects: entities, contracts and repositories, CatFactory provides an easy way to generate repetitive code and focus on complex logic.

C++ Object Relational Mapping (ORM)- Eating the Bun – Part 1 of N

C++ Object Relational Mapping (ORM)- Eating the Bun – Part 1 of N

Object Relational Mapping is the process of mapping data types between an object-oriented language as C++ to a relational type system as SQL. So what is the challenge? C++ has different types of primitive types as,intchar, float, double and variations of that. So it’s a real challenge to map all these to an actual SQL type. There may be or may not be an exact type that is similar to the C++ types. Say for,float C++ and SQL may support a different kind of standards too. So there are different tools to do this job. There are a lot of matured libraries too out there in the market. ODB is one that is really nice.

Computer Temperatures, Fan Speeds, etc.

Computer Temperatures, Fan Speeds, etc.

I have a homebuilt desktop with an ASUS P6T motherboard. It’s about 7-8 years old, but still quite powerful and functions beautifully. ASUS originally provided PC Probe II to monitor temperatures and fan speeds, but stopped supporting it for the P6T when Windows 10 came out. And since then, I’ve been operating without a satisfactory sensor app. Unfortunately, the 3rd party sensor apps available are a bit quirky, or non-intuitive, or can’t be configured the way I’d like. Then again, perhaps I’m just overly picky.

Dynamic Components in Angular with TypeScript

Dynamic Components in Angular with TypeScript

Today, we will be going through the step by step discussion of how to create dynamic components in Angular 2/4 and how to set the value of dynamic control and get the value from the dynamically generated component. Dynamic Components are those components which generate at runtime. Runtime in the sense, we have a running application and if we want to render some component on any event like button click event, then it will be called the Dynamic Component. So, this article will cover four things about Dynamic Components as follows:

Easy to Use Parallel foreach, that can be Magnitudes Faster than the .NET Version

Easy to Use Parallel foreach, that can be Magnitudes Faster than the .NET Version

I’d like to share a quick solution for a parallel foreach loop, which can potentially increase the performance of certain applications currently using the built in version introduced in .NET 4.0. This custom version is suited to be used in nested loops, where the outer one needs to be processed sequentially. The number of threads has to be set manually, this could provide additional control over the threads.

Tightly Integrating a Lightweight CMS with Angular under .NET Core

Tightly Integrating a Lightweight CMS with Angular under .NET Core

ASP.NET Core combined with Angular is becoming an increasingly popular tech stack for building interactive web apps. However, if you want to manage the content of such a web app, your only choice has been to use a headless CMS service. This can be overkill especially for smaller web apps and doesn’t allow for easy previewing of content changes. Lynicon CMS provides SPA content management with preview for ASP.NET Core, which unlike the more usual headless CMS setup allows you to immediately view the effects of your content changes. It is lightweight and quick to set up, and allows for content to be stored in a file rather than a database.

A variety of breakfast-lunch treats await you; mimosas and bloody marys, eggs Benedict, omelets, scrambled eggs, French toast, Belgian waffles, bagels, pasta, chicken, seafood, and carved prime rib. The list is endless. The only limitations are your budget and how much you can and want to eat.

End to End(E2E) Tests in Angular Application Using Protractor

End to End(E2E) Tests in Angular Application Using Protractor

 In this article, we will learn how we can create end to end tests (e2e) for our Angular application. We will be using an existing end-to-end testing framework, which is nothing but, Protractor. Protractor runs your tests against your application running in a real browser, in the same way your user may perform the actions. I will be using an existing application which is available in my GitHub profile. The same can be available in the source code section. Please do share your feedback with me. I hope you will like this article. Let’s start coding.

Microservices with Kubernetes, Docker, Helm. (Part 1) Generic configuration and API Gateway

Microservices with Kubernetes, Docker, Helm. (Part 1) Generic configuration and API Gateway

Using Kubernetes to deploy services and support micro-service architectures is nice and is pretty fast. It is just better than setting up things one by one. It`s also really good for DevOps people, trying to automate deployment and patches. However, much like any other system, the question of parametrization is somehow hard to solve. The purpose of DevOps team is to streamline everything and reduce the amount of time a patch gets into production, the purpose of the Dev Team is to deliver and integrate the IDE backbone with the streamline, the Security Team must ensure that everything is as hardened as possible.
