How We Automated Static Go Builds with Docker — No More Escaping Hell

The article discusses the development of the 'go-builder' tool to automate static Go builds using Docker.
The tool helps in maintaining predictable, portable, and declarative builds without relying on complex Makefiles.
Key features of 'go-builder' include using CGO_ENABLED=1, musl-gcc instead of the default linker, embedding version info, and cross-compiling for multiple architectures.
The tool simplifies the build process and ensures that binaries remain static, providing a consistent and controlled approach to building Go applications.

What Is JA3? The Silent Fingerprint Behind Every HTTPS Connection

JA3 is a method to create a unique fingerprint of how a client behaves at the TLS level by encoding raw data and hashing it using MD5.
It is useful for bot and malware detection, application fingerprinting, and fraud analytics by distinguishing TLS handshakes and behaviors.
JA3 serializes fields into a comma-separated string and produces a unique hash representing the client's TLS negotiation process.
Cloudflare WAF uses JA3 to protect sensitive API endpoints with multiple filters.

WebSockets Explained: How Real-Time Chat Apps Work Behind the Scenes

Real-time chat apps like WhatsApp or multiplayer games like BGMI work smoothly using WebSockets, which enable constant two-way communication between clients and servers.
Traditional applications communicate over standard HTTP connections, where a request is sent, a temporary connection is formed, data is received, and the connection is closed, unlike the persistent connection of WebSockets.
WebSockets start as an HTTP request and, if accepted by the server, upgrade to a persistent connection that allows both client and server to send and receive messages freely without waiting, unlike the polling method used in HTTP for real-time experiences.
Major companies like Slack, Trello, and Google Docs leverage WebSockets to enable real-time collaboration and instant updates, showcasing the efficiency and effectiveness of using WebSockets for real-time applications.

AI-Powered Image Translator using React JS, AWS Textract, Translate, and Polly

AWS operations in the AI-Powered Image Translator are securely performed on the backend, ensuring no direct interaction with AWS SDKs or credentials from the frontend.
It is recommended to use the AWS CLI to configure credentials globally for the machine, rather than hardcoding them in the code.
Steps involve installing AWS CLI, creating an IAM user with programmatic access, and storing the credentials securely in ~/.aws/credentials and ~/.aws/config.
The article also highlights the application's components, such as the uploaded image, user interface, and the translation with audio output, providing a comprehensive overview of the process.

Build a Private dApp on Oasis Sapphire

Sapphire is a confidential EVM runtime built on the Oasis Network, allowing Solidity developers to build private dApps without learning a new stack.
Sapphire introduces confidentiality to smart contract execution by encrypting input, output, and internal state inside a Trusted Execution Environment like Intel SGX.
Developers can deploy existing contracts to Sapphire with no changes, and adding privacy logic can unlock entirely new capabilities.
Sapphire enables the development of dApps with enhanced privacy features, such as a 'dead man’s switch' smart contract example, while keeping the experience similar to Ethereum development.
