We will explore concepts in Angular that seem simple but are very powerful and critical for the application architecture. By Max Schulte is engineer consultant at Thinktecture.

Every Angular developer knows the async pipe. It is almost always present when writing components and using some observables or promises. This article will explore how it works and for what it is suitable.

The article then pays attention to:

• Where do we profit from using the async pipe?
• How does the async pipe work?
• The async pipe in action
• An alternative to the async pipe

As alternatives to the async pipe, you can resolve the observable or promise in your component. This article explores the async pipe, how it works, what it is used for, and examines its source code in detail. We have seen how to use it and provided examples, demos, and alternatives. Now it is up to you to decide where to use it in your projects and when. This conclusion might help you further with that decision. Good read!

Even with the most optimized code, it is hard for eCommerce sites to reach a 100 out of 100 score on PageSpeed Insights unless they serve only static HTML. By Misko Hevery.

By removing all of the JavaScript execution we can get a perfect score of 100 and pass with flying green colors! But, therein lies the problem. These pages are static. We need our pages to deliver content dynamically, full of interaction and life. How can we serve static HTML to receive high scores, but at the same time provide rich interaction?

The reason is that all existing frameworks are not designed with time-to-interactive in mind. They have complex bootstrap processes which require a lot of code to be downloaded and executed before the page can become interactive. Yes, most support server-side-rendering to get a quick flash of initial content, but the first thing they need to do is to download all of the templates on the page and execute them to rehydrate the page and make it interactive.

Introducing Qwik, an open-source DOM-centric, resumable web-app framework designed for best possible time-to-interactive, by focusing on resumability of server-side-rendering of HTML and fine-grained lazy-loading of code. The basic goal of Qwik is to focus on the time-to-interactive metric by delaying JavaScript as much as possible to take advantage of the browser’s lazy loading capabilities.

Qwik’s goal is to crush time-to-interactive to a blink of an eye on the slowest mobile device. We want to serve static pages to the user so that they are fast, but retain all of their interactivity. We want to have our cake and eat it too! Good read!

From listening better to citizens, to making operations more efficient, AI brings multiple benefits to governments to make better decisions. By Hugo Cen.

The continuous progress of technology has led to different government organizations having to modify their structures, as well as the way in which they execute their processes.

Nowadays, applying tools such as Artificial Intelligence (AI ) in government is essential, since AI makes all operations more efficient, allows citizens to listen better, have greater sensitivity about what they are asking for, what they need, and know the general feeling you have.

According to Christian Peñaloza , doctor in Cognitive Neuroscience, there are three categories into which the main current benefits of Artificial Intelligence in government can be grouped. These are:

• Perfect existing processes: it is based on automating many of the tasks that are carried out, particularly those that consist of data collection and procedures that are carried out for the government
• Improve decision-making with data : here AI can be used to analyze all the data collected and, from it, make better decisions
• Crime prevention: it is more focused on using this technology to be able to detect certain frauds, for example, many use it in the part of the Tax Administration Service (SAT) in collaboration with banks, to be able to detect strange movements and to be able to identify transactions that are not legitimate. It is also implemented in security departments to prevent crime

What’s more, data should be the mainstay of current public policies since, as mentioned above, they generate enormous value. Good read!

Day by day the number of machine learning models is increasing at a pace. With this increasing rate, it is hard for beginners to choose an effective model to perform Natural Language Understanding (NLU) and Natural Language Generation (NLG) mechanisms. By Purnasai Gudikandula.

The wide availability of other sequence-to-sequence learning models like RNNs, LSTMs, and GRU always raises a challenge for beginners when they think about transformers. And it is important to a beginner to have basic knowledge of these models before they get to know more about transformers. If you still struggle why not RNNs, LSTMs, and GRUs, here we listed a few important points that can help you out.

The article does a good job of explaining:

• Why Transformers?
• Transformer architecture
• Transformer architecture flow
• Code for language translation
• Transformers for tomorrow

Source: ARXIV via https://deeplobe.ai/machine-learning-for-transformers-explained-with-language-translation/

Transformers are pretty versatile and can be used in a variety of NLP tasks, such as; Machine Translation, Text Summarization, Speech Recognition, Question-Answering systems, and so on. Well worth your time!

Flutter is great for making beautiful cross-platform UIs with its everything is a widget concepts. But how do you actually move data around your application. By Jay Hackett.

A huge paradigm shift when working in Flutter is thinking declaratively. The way most of our brains work make it easy to understand imperative programming concepts. When our code is organized as sequential steps we can follow the code for one branch of code to the next. When programming declaratively we describe what needs to be done and our system responds based on the action we describe.

The article’s content is split into:

• Shift your design thinking to be declarative
• Don’t be afraid to re-draw
• A look at Flutter Ephemeral State
• But what about when I need to keep track of some global state? Lets talk App State

In conclusion, state is one of those things that are at the core of any application we build. It doesn’t matter what method of state management that you use. What really matters is that you understand the decision behind when to use the types of state within you app. It will help you app become more maintainable as your state management design builds consistency.

Scrum Programs represent a collection of related projects. The objective of a program is to produce business results as they have been identified in the Program Vision Statement. By 59secondsagile.com.

The Prioritized Program Backlog includes Product Backlogs for every project within the program. Scrum at the Program level includes five (5) high-level processes.

The article then describes how to:

• Create program or portfolio components
• Review and update Scrum guidance body
• Create and prioritize program or portfolio backlog
• Coordinate program or portfolio components
• Scrum programs: Retrospect program or portfolio releases

Whenever Scrum is used to manage projects within a Scrum Program or Portfolio, the recommendation is the Agile principles are followed. It is a well-known fact that in order to be successful at the program level with Scrum, small adjustments may be made to the tools and the organizational structure.

Data modeling in NoSQL is trickier than normal SQL. Sometimes, it goes against our intuition. Especially coming from an SQL background, I found it hard to comprehend the various reasons behind the data modeling in NoSQL databases like AWS DynamoDB or Firebase. By Mohammad Faisal.

The article explains three strategies for modeling one-to-many relationships and the scenarios in which you can use them:

• Denormalization + Complex Attribute
• Denormalizaton + Duplication
• Composite Primary Key + Query

Denormalization is a dirty word for SQL developers. But in the NoSQL world, it has its use cases. Designing a NoSQL database is no joke. You have to put a lot of effort into designing one and think about all the possible access policies beforehand. Otherwise, you can’t revert or change the data modeling very easily down the road.
