Scaling Go Tests with Smart Naming Conventions

In the Go ecosystem, testing with the real thing is preferred, but it became time-consuming with the growing codebase.
Defined test categories: Unit Tests, Integration Tests, and End-to-End (E2E) Tests for different testing purposes.
Initially used environment variables for different test categories but faced issues. Then tried regex in test names but had problems in a monorepo.
The final solution was to use Go-Native Prefix Naming: TestUnit_ for fast, isolated tests and TestIntegration_ for cross-package/dependency tests, enabling faster local runs, clear intent, simplified CI, and IDE compatibility.

Linear design: The SaaS design trend that’s boring and bettering UI

Linear design is a popular design trend, particularly for SaaS products, evolving rather than fading into obscurity, characterized by straightforward, sequential layouts.
Advantages of linear design include reducing cognitive load, making users less anxious and more productive, increasing conversions, being highly performant, and supporting accessibility.
However, the oversaturation of linear design can lead to products looking monotonous and lacking variety, making them less visually appealing and enjoyable to use.
The trade-off for better UX with linear design is the risk of products looking similar, potentially leading to decreased memorability and recognizability due to a lack of unique brand identity.
While linear design continues to do well, its current form may not be future-proof, with trends likely to evolve towards more individuality and boldness.
Linear design tips include using dark mode effectively, utilizing bold typography creatively, incorporating complex gradients and bold colors, and considering glassmorphism sparingly for a sleek glass effect.
The linear design trend emphasizes linearity, with principles like one-dimensional scrolling, aligned text, minimal CTAs, and minimal subject matters contributing to a streamlined user experience.
Maintaining accessibility in design is essential, and linear designs inherently simplify design, making them easier to make accessible, contributing to better user experiences for all users.
The future of design trends may involve incremental updates to existing trends like linear design, focusing on quality of life improvements rather than drastic changes annually.
While linear design has grown in popularity, there is a need for continued improvement to avoid designs becoming too similar, with opportunities to introduce more color, bolder typography, and unique visual identities.
Linear design continues to be a significant trend, but there is a call for innovation and differentiation within the trend to maintain visual appeal and user engagement.

Auto-Healing Azure Integrations with Scheduled Retries in Service Bus + Azure Functions

Transient failures in downstream systems led to the need for a controlled, scheduled retry mechanism in an Azure integration project.
The solution involved implementing an auto-healing pattern using Azure Service Bus for scheduling retries and Dead Letter Queue (DLQ) support, along with Azure Functions for message processing.
The high-level retry flow included incrementing retry count on transient failure, scheduling re-queued messages with a delay, and moving messages to DLQ after reaching the maximum retry limit.
This approach, which leveraged Azure Service Bus and Azure Functions, provided a serverless, cost-effective, and Azure-native pattern to improve resilience in message processing flows.

I Fixed My Slow Nginx + Gunicorn Setup — Here’s How It Became 3X Faster

The author, a developer, shares how he improved the speed of his Nginx + Gunicorn setup for his Django app on a CentOS 9 EC2 Server.
Initially facing a 3x speed difference between Nginx routing to the Django server versus Gunicorn, he debugged and found a misconfiguration in the binding address in Gunicorn.
The solution involved creating a Gunicorn socket service, updating Gunicorn to use the socket instead of a network address, and then updating Nginx to communicate via the Unix socket.
After restarting the services, the unnecessary network overhead was removed, resulting in a significant speed improvement with Gunicorn responding now ~3X faster.

Most Performance Problems Are Management Problems

When systems start slowing down, the immediate question from managers is usually 'Can you fix it?' rather than understanding what changed or considering a change in the system design.
In many cases, performance problems in systems are not solely due to technical issues like bad queries or memory leaks, but are often rooted in management decisions and organizational structures.
The inefficiencies in code are often just visible symptoms of deeper management problems within the organization, leading to slow systems such as clunky frontends, crawling APIs, and overworked databases.
One particular project highlighted had slow page load times due to nested microservices and convoluted system architecture, showcasing how management decisions can impact system performance.

C++ in Embedded Systems: Modern Practices for Resource-Constrained Environments

C++ is preferred over C for embedded systems due to modern features and tools that can help optimize resources.
Modern C++ standards like C++11, C++14, C++17, and C++20 provide smart pointers, constexpr, templates, and std::chrono for efficient embedded programming.
Smart pointers from C++11 help in handling memory cleanup automatically, constexpr allows pushing work to compile time, templates aid in writing flexible code without runtime cost, and std::chrono is useful for real-time functions.
While C++ offers powerful features for embedded systems, some aspects like heavy exception handling may not be suitable, and it is commonly paired with other tools like pointers and bitwise operations for hardware interactions.
