7 REST API Design Principles That Separate Good Developers from Great Ones

REST API design is essential for creating scalable, maintainable, and user-friendly interfaces.
Statelessness is crucial for scalability as it enables horizontal scaling and simplifies caching.
Resource-oriented design focuses on nouns (resources) rather than verbs to create better endpoints.
Hypermedia (HATEOAS) guides clients on how to interact with APIs, improving discoverability and future-proofing.
Using proper HTTP status codes like 200, 201, and 400 is essential for effective communication.
Versioning helps avoid breaking changes with industry-standard approaches like URL Path or Header.
Pagination should be implemented correctly to manage large datasets efficiently.
API security goes beyond basic auth and includes techniques like JWT/OAuth 2.0 and input validation.
APIs designed with these principles can scale, reduce support tickets, and get adopted faster by developer communities.
Great APIs are built by developers who understand and apply these fundamental principles.

New Java 21 Feature : A Guide to Virtual Threads in Java!

Java has introduced Virtual Threads, a new feature for running multiple tasks concurrently in a simpler and more efficient way.
Threads in Java are like helper workers that perform different tasks.
Virtual Threads, part of Project Loom, are lightweight threads created by JVM, enabling the creation of thousands of threads without memory concerns.
Virtual threads do not block OS threads, use less memory and CPU, and are suitable for I/O-heavy tasks.
To create a virtual thread, you can use Thread.startVirtualThread(() -> { // Your logic });.
Virtual threads offer advantages like clean and readable code, simplifying complex thread management, and handling numerous tasks effectively.
They are ideal for applications handling many users or requests, especially I/O-heavy tasks.
However, for CPU-intensive tasks, virtual threads may not provide significant benefits.
Virtual threads eliminate the need for learning complex async or reactive programming and allow efficient handling of tasks.
Overall, virtual threads are a significant improvement in Java, enabling the creation of clean and efficient code for concurrent processing.

Deleting vs Replacing Names

When deidentifying personal data, structured data can have real names deleted or replaced with random names without impacting privacy.
For structured data in databases, removing a column with names is a necessary step for deidentification, but replacing names doesn't affect privacy much.
In cases like software testing with patient data, replacing real names with randomly generated names can be useful.
For unstructured data like doctor's notes, replacing names with synthetic names is better for privacy than just removing them.
Replacing names in unstructured data helps maintain privacy as software might not accurately identify all names.
Synthetic names obscure failures of data deidentification software better than 'NAME REDACTED' placeholder.
Using synthetic names in unstructured text deidentification is preferable as software errors are less obvious.
An effective process for synthesizing names should have a low error rate and be unbiased.
Synthesizing names rather than removing them is better if the error rate is sufficiently low and unbiased.
Deidentification software often has error rates, but it doesn't need to be zero to comply with privacy regulations like HIPAA.

How to use the Interest Invoker API for better, more accessible UX

Interest Invoker API is an experimental API that aims to simplify how developers manage UI components like modals and popovers without the need for extensive JavaScript.
It holds promise for enhancing accessibility in web development but is currently limited to Chromium-based browsers like Chrome.
The API allows styling of declarative controlled elements and aims to reduce overreliance on JavaScript for common UI patterns.
Developers can create popovers using the Interest Invoker API by using specific attributes like interesttarget and popover.
Styling popovers is possible by applying CSS to elements with specific attributes.
The API provides pseudo-classes like :has-interest for styling elements based on user interactions.
It also supports custom delays for popover appearance and disappearance when hovered over.
The Interest Invoker API enables multiple actions on elements using attributes such as commandfor and command.
Developers can implement custom JavaScript behavior using the InterestEvent interface to trigger actions when a user indicates or loses interest.
Overall, the Interest Invoker API offers a declarative approach to user intent and interaction, improving accessibility and user experience in web applications.

The Kill Switch: A Coder's Act of Revenge

A fired contract programmer embedded a digital kill switch in a logistics company's infrastructure, causing chaos.
The act highlighted the peril of insider threats in the digital age and the need for better security protocols.
The developer meticulously planned the sabotage by mapping infrastructure, building redundancies, and obfuscating the payload.
He maintained access post-termination through overlooked VPN keys and testing the kill switch in a test environment.
Operational complacency, lack of centralized security measures, and poor offboarding processes allowed the attack to unfold.
The attack was executed through privileged access, crafting a logic bomb, embedding it within legitimate procedures, causing significant fallout.
Federal authorities tracked and arrested the developer under the Computer Fraud and Abuse Act, emphasizing the need for heightened cybersecurity measures.
Tech leaders are urged to enforce least privilege, monitor for anomalies, and tighten security fundamentals to prevent similar attacks.
The incident underscores the importance of enhancing security practices and fostering a culture of vigilance in the face of evolving cyber threats.
This cautionary tale serves as a reminder to organizations to prioritize cybersecurity and mitigate risks posed by insider threats and lax security measures.
