Create CRUD endpoints using Hyperlambda

,

Hyper implies web, and lambda implies function – Hence, Hyperlambda translates into "web functions", and this is a fairly accurate description. However, hyper also implies "super fast", and by super fast here, I mean super fast! 1 minute and 45 seconds was what I needed to create CRUD endpoints wrapping my database table, manually creating my endpoints in the following video, while explaining how I did it simultaneously.

According to modern studies in the subject, the number of lines of code your project consists of, is directly proportional to the amount of energy and resources you’ll need to spend maintaining it. Hence, the fewer lines of code, the fewer resources are required to maintain it. In the video above, I copy and paste 50 lines of code, and I end up with 4 HTTP REST CRUD endpoints. Comparing this to C# is arguably unfair. Simply the boiler plate code for my Controller, would probably end up exceeding this number. You can find my code for all endpoints below.

Bridge Design Pattern in Modern C++

,

Bridge Design Pattern is a Structural Design Pattern used to decouple a class into two parts — abstraction and it’s implementation — so that both can be developed independently. This promotes the loose coupling between class abstraction and its implementation. You get this decoupling by adding one more level of indirection i.e. an interface that acts as a bridge between your original class and functionality. Insulation is another name of the Bridge Design Pattern in the C++ world.

"All problems in computer science can be solved by another level of indirection." — David Wheeler

C++17: Polymorphic Allocators, Debug Resources and Custom Types

,

In my previous article on polymorphic allocators, we discussed some basic ideas. For example, you’ve seen a pmr::vector that holds pmr::string using a monotonic resource. How about using a custom type in such a container? How to enable it? Let’s see.

The Goal

In the previous article there was similar code:

Types of Loops in C and C++?

,

Loops in a programming language is a piece of code that get executed repeatedly until the specified condition becomes false. A loop consists of two parts, a block of statements and a condition that control the loop.

Loops mainly consisted of three statements – initialization condition, test condition, update condition.

Health Checks with ASP.NET Core and Kubernetes

,

Health checks are a fundamental part of our APIs. I guess they fall in that category of "non-functional-but-heavily-required" things. More or less like a good part of the infrastructure code.

They don’t add business value per se but have an enormous impact for those in IT, like DDD and design patterns. You can normally see them in conjunction with container orchestration or monitoring tools to ensure that the system is alive and kicking.

HTTP and Scalable Software Systems

,

If you think about the World Wide Web, it’s easy to imagine it as a single software system. Once you do, you realize it’s the largest software system the world has ever created — probably by hundreds of orders of magnitude. It contains trillions of lines of code, hundreds of millions of servers, and billions of clients, running thousands of different programming languages. Still, it works more or less as we expect it to work. So, what made it possible for humans to create such an enormous software system? The answer is simple: HTTP!

The HTTP protocol allows us to create perfect encapsulation. The client and the server don’t need to know anything about each other, besides the URL, HTTP verb, and what parameters to pass in and expect as output. This allows billions of clients to interact with each other, without knowing (almost) anything about each other. If you reduce it down to its basic components, it becomes painfully obvious that the following is a recipe for winning.

Easy REST APIs With AutoRest

,
It’s easy to REST with AutoRest.
“We live in an API-driven world,” said Julia Kreger, OpenStack Ironic project team lead and principal software engineer at Red Hat.

API is an acronym for “Application Programming Interface.” It has a long history since the first computer programs were written. At first, APIs form “contracts” for accessing resources from the operating system, software libraries, or other systems.

Hashing in Java Vs. C++

,
Learn more about the differences and similarities between hashing in Java and C++.

Java and C++ are somewhat syntactically similarly languages that have diverged over time. Java was loosely inspired by C++, but initially didn’t adopt C++’s template structures, nor did it require C++’s header/content file separation, and of course, it used the JVM and compiled to bytecode rather than machine code.
