If you are struggling to come up with your app idea, it’s okay. You’re not alone. It is common for app developers to face this type of challenge given the millions of apps in the App Store. Also, thinking of an app idea isn’t always as easy as it sounds. By Pat Enriquez.

Most ideas are born from putting together old and existing ideas. So don’t be discouraged if you find an app in the App Store with the same idea as yours and don’t just scrap that app idea.

The article then describes these strategies:

• The remix strategy
• Scratch your own itch
• Improve what already works

When it comes to app development, oftentimes, apps are made by thinking about how they can solve the problems of app developers themselves. Interesting read!

Spring Supports GraphQL requests over HTTP, Websockets and RSockets. Securing an Spring GraphQL application does not differ from securing a Web application. Mainly, Spring GraphQL needs to ensure context propagates from WebFlux to the data fetching layer so that we can use Security annotations or access the authenticated principal in @SchemaMapping methods. This should work for HTTP and WebSocket. By Ruchira Madhushan Rajapaksha.

In this tutorial, we will develop a Reactive Spring boot application that secures an exposed GraphQL API using JWT authentication. We will be having a separate rest endpoint to generate the JWT, which we will use to validate the GraphQL endpoint. For more information about JWT, just refer to the following guide.

Further in this article you will find information on:

• Application Setup with SpringBoot
• JWT Utility
• Spring Security Configuration
• SecurityContextRepository
• AuthenticationManager

To apply more fine-grained security, we can add Spring Security annotations such as @PreAuthorize or @Secured to service methods involved in fetching specific parts of the GraphQL response. This should work due to Context Propagation that aims to make security, and other contexts, available at the data fetching level. Interesting read!

In June 2023 an IBM computing executive claimed quantum computers were entering the “utility” phase, in which high-tech experimental devices become useful. In September, Australia’s Chief Scientist Cathy Foley went so far as to declare “the dawn of the quantum era”. Obviously, quantum computers are having a moment. But – to step back a little – what exactly are they? By Christopher Ferrie.

In the 1990s, physics and computer science collided when it was discovered that some problems could be solved much faster with algorithms that work directly with complex numbers as encoded in quantum physics. The next logical step was to build devices that work with light and matter to do those calculations for us automatically. This was the birth of quantum computing.

The article explains:

• What is a quantum computer?
• Why does quantum computing matter?
• What is the current landscape?
• Superconductors, ions, silicon, photons
• Where will the quantum future take us?

Commercial spin-offs of technology such as quantum sensing are also on the horizon. The demonstration of a genuine “quantum advantage” will also be a likely development. This means a compelling application where a quantum device is unarguably superior to the digital alternative. Super interesting read!

The API gateway component in a cloud native architecture is critical because it offloads critical API security and policy functionality to a common place, allowing the backend APIs and services to focus on business logic. API authentication, authorization, audit, throttling and similar tasks can be complex and difficult to get right, so many organizations choose an API gateway to handle them. By Christian Posta and Peter Jausovec.

Further in the article:

• How to use JWTs to authenticate S2S communication
  • Option 1: Use an STS to issue tokens
  • Option 2: Have the service sign its own tokens
• Where things can go wrong with JWT
• JWT Complexity is where service mesh simplifies things

We’ve covered some ways JWTs can be used to represent service identity and suggested areas of concern. There are several areas to closely watch in your services architecture to avoid security holes. If these are not bulletproof, you will give attackers opportunities to compromise your system.

To guard against replaying the bearer token, you must limit exposure by setting brief expiration times, ideally just a couple of minutes. This puts more onus on the services to refresh their JWTs for their requests. Setting the expiration for hours, days, or months happens too often. This is a big security hole. Nice one!

Both TLS and SSL are protocols that help you securely authenticate and transport data on the Internet. But what’s the difference between TLS vs SSL? And is it something you need to worry about? By kinsta.com.

In this article, you’ll learn the key differences between TLS vs SSL, as well as how both protocols connect to HTTPS. You’ll also learn why, as an end-user, you probably don’t need to worry too much about TLS vs SSL or whether you’re using an “SSL certificate” or a “TLS certificate”.

The content of the article:

• What is the difference between TLS vs SSL?
• How TLS and SSL work at a basic level
• Why is it called an SSL certificate and not a TLS certificate?
• Why you should use TLS and not SSL (and why you probably already are even if you don’t know it)

To sum everything up, TLS and SSL are both protocols to authenticate and encrypt the transfer of data on the Internet. The two are tightly linked and TLS is really just the more modern, secure version of SSL. Good read!
