Discussion About Rust Programming?

What is Rust?

Rust is a systems programming language that runs blazingly fast, prevents segfaults, and guarantees thread safety.

Features

Zero-cost abstractions
Move semantics
Guaranteed memory safety
Threads without data races
Trait-based generics
Pattern matching
Type inference
Minimal runtime
Efficient C bindings

Rust is a programming language that helps you write faster, more reliable software. High-level ergonomics and low-level control are often at odds with each other in programming language design; Rust stands to challenge that. Through balancing powerful technical capacity and a great developer experience, Rust gives you the option to control low-level details (such as memory usage) without all the hassle traditionally associated with such control.

Rust is intended to be a language for highly concurrent and highly safe systems, and "programming in the large", that is, creating and maintaining boundaries that preserve large-system integrity. This has led to a feature set with an emphasis on safety, control of memory layout, and concurrency. Performance of idiomatic Rust is comparable to the performance of idiomatic C++.

Small Discussion about APEX Programming?

What is APEX?

Apex is a proprietary language which has been developed by Salesforce.com. Apex is a strongly typed, object-oriented programming language that allows developers to execute flow and transaction control statements on the Force.com platform server in conjunction with calls to the Force.com API.

Apex Code is designed explicitly for expressing business logic and manipulating data, rather than generically supporting other programming tasks such as user interfaces and interaction.

Apex Code is therefore conceptually closer to the stored procedure languages common in traditional database environments, such as PL/SQL and Transact-SQL. But unlike those languages, which due to their heritage can be terse and difficult to use, Apex Code uses a Java-like syntax, making it straightforward for most developers to understand.

And like Java, Apex Code is strongly typed, meaning that the code is compiled by the developer before it is executed, and that variables must be associated with specific object types during this compile process. Control structures are also Java-like, with for/while loops and iterators borrowing that syntax directly.
Because Apex Code is a process and data language, developers will primarily interact with APIs to query, manipulate and save information in their custom and standard objects.

Developers can select data using the existing Salesforce Object Query Language (SOQL) syntax already found in the existing Web services API, as well as a new addition to that syntax that can retrieve information from multiple objects via a single query.

Small Introduction About Delphi Programming?

What is Delphi Programming?

Delphi is both an object oriented programming language (OOP) and an Integrated Development Environment (IDE). Published by the Embarcadero company (formerly CodeGear and more formerly Borland), Delphi is an alternative to language such as Visual Basic offering development with both rapidity and good quality.

It originated from the Pascal language, which then became Object Pascal (pascal with objects support). Delphi is based on the Object Pascal language. The IDE runs on Windows, but the compiler targets Windows, macOS, iOS, Android, and Linux. Third party add-ins provide the ability compile to JavaScript for web development.

Delphi includes the RunTime Library (RTL) that provides basic functionality across all the platforms. For Windows it provides the Visual Component Library (VCL), and for cross platform development it includes FireMonkey (FMX).

Delphi includes a code editor, a visual designer, an integrated debugger, a source code control component, and support for third-party plugins. The code editor features Code Insight (code completion), Error Insight (real-time error-checking), and refactoring.

The visual forms designer has traditionally used Visual Component Library (VCL) for native Windows development, but the FireMonkey (FMX) platform was later added for cross-platform development. Database support in Delphi is very strong. A Delphi project of a million lines to compile in a few seconds – one benchmark gave 170,000 lines per second.

It provides interfaces for the programmer to build an application using the Extensible Markup Language (XML), Extensible Stylesheet Language (XSL), Simple Object Access Protocol (SOAP), and Web Services Description Language (WSDL).

Small Discussion about Thingspeak?

What is ThingSpeak?

ThingSpeak is an open-source Internet of Things (IoT) application and API to store and retrieve data from things using the HTTP protocol over the Internet or via a Local Area Network.ThingSpeak was originally launched by ioBridge in 2010 as a service in support of IoT applications.
ThingSpeak™ is an IoT analytics platform service that allows you to aggregate, visualize and analyze live data streams in the cloud.

ThingSpeak provides instant visualizations of data posted by your devices to ThingSpeak. With the ability to execute MATLAB® code in ThingSpeak you can perform online analysis and processing of the data as it comes in. ThingSpeak is often used for prototyping and proof of concept IoT systems that require analytics.

ThingSpeak allows you to aggregate, visualize and analyze live data streams in the cloud.

Some of the key capabilities of ThingSpeak include the ability to

Easily configure devices to send data to ThingSpeak using popular IoT protocols.
Visualize your sensor data in real-time.
Aggregate data on-demand from third-party sources.
Use the power of MATLAB to make sense of your IoT data.
Run your IoT analytics automatically based on schedules or events.
Prototype and build IoT systems without setting up servers or developing web software.
Automatically act on your data and communicate using third-party services like Twilio® or Twitter®.

Small Discussion about Minikube?

What is Minikube?

Minikube is a tool that makes it easy to run Kubernetes locally. Minikube runs a single-node Kubernetes cluster inside a VM on your laptop for users looking to try out Kubernetes or develop with it day-to-day.

Minikube supports Kubernetes features such as:

DNS
NodePorts
ConfigMaps and Secrets
Dashboards
Container Runtime: Docker, rkt, CRI-O and containerd
Enabling CNI (Container Network Interface)
Ingress

When using a single VM of Kubernetes, it’s really handy to reuse the Minikube’s built-in Docker daemon; as this means you don’t have to build a docker registry on your host machine and push the image into it -

We can just build inside the same docker daemon as minikube which speeds up local experiments. Just make sure you tag your Docker image with something other than ‘latest’ and use that tag while you pull the image. Otherwise, if you do not specify version of your image,

it will be assumed as :latest, with pull image policy of Always correspondingly, which may eventually result in ErrImagePull as you may not have any versions of your Docker image out there in the default docker registry (usually DockerHub) yet.

Small Discussion about Polymer.Js?

What is Polymer.Js?

Polymer.js is a JavaScript library created by Google that allows reusing the HTML elements for building applications with components. Polymer is an open-source JavaScript library developed by Google developers

Polymer provides a number of features over vanilla Web Components:

Simplified way of creating custom elements
Both One-way and Two-way data binding
Computed properties
Conditional and repeat templates
Gesture events

Polymer.js places a hefty set of requirements on the browser, relying on a number of technologies that are in still in the process of standardization (by W3C) and are not yet present in today’s browsers.

Examples include the shadow dom, template elements, custom elements, HTML imports, mutation observers, model-driven views, pointer events, and web animations. These are marvelous technologies, but at least as of now, that are yet-to-come to modern browsers.

The Polymer strategy is to have front-end developers leverage these leading-edge, still-to-come, browser-based technologies, which are currently in the process of standardization (by W3C), as they become available.

The recommended polyfills are designed in such a way that (at least theoretically) will be seamless to replace once the native browser versions of these capabilities become available.
