Apple M1+ web developers are cheating. You should do that, too

Web development in certain communities has reached a level of bloat comparable to Java, indicating a lack of learning from past mistakes.
Developers using Apple M1/M2/M3/M4 Macs can efficiently run workloads like Next.js, VSCode, and React due to the Unified Memory Architecture.
Apple's MacOS employs memory compression and aggressive swapping to handle memory leaks and bloated applications effectively.
Linux users can implement memory compression using zram kernel module to mitigate memory leaks in a similar manner to MacOS.
To implement zram on Linux, users can create a pseudo-swapfile using commands such as sudo zramctl and swapon.
Creating a traditional swapfile on Linux involves steps like allocating a file, cleaning its contents, setting it up as a swapfile, and activating it.
Adjusting swappiness and vfs_cache_pressure settings in Linux can help maintain a balance between RAM usage and performance.
Despite these measures, memory leaks are inevitable and may still cause performance issues over time.
The ethical implications of supporting a development ecosystem plagued by bloat and memory leaks are pondered, questioning the sustainability of such practices.
Further topics include discussions on productivity tools, UI libraries, and Streams Oriented Programming.

🚦 Rate Limiting in NestJS Using @nestjs/throttler

Rate limiting controls the number of requests a user or system can make to a server in a given period to prevent flooding.
Implement rate limiting in NestJS using @nestjs/throttler package to enhance server security and stability.
It prevents increased server load, slower response times, downtime, or crashes caused by excessive requests.
Installation involves npm install @nestjs/throttler and setting up multiple throttling rules in AppModule.
Global rate limits for all routes can be configured along with overriding limits, skipping limits, or applying based on users.
By exceeding limits, users get a 429 Too Many Requests error indicating reached limits.
@Throttle() decorator customizes limits for specific routes, while @SkipThrottle() excludes controllers or routes from rate limiting.
Custom guards, like EmailThrottlerGuard, enable rate limiting based on user emails instead of IP addresses for personalized limits.
Multiple throttle profiles like 'short' and 'long' offer varied limits for different routes for better control and security.
Using @nestjs/throttler allows for easy global rate limit application, per-route overrides, custom user tracking, and multiple limit strategies.

Will Kotlin Coroutines Become Obsolete?

Kotlin Coroutines have revolutionized asynchronous programming, offering a cleaner alternative to callbacks and reactive streams.
Coroutines introduced structured concurrency, ensuring responsible handling of concurrent tasks and reducing bugs.
Java's Project Loom with virtual threads poses a challenge to coroutines, focusing on efficiency and debugging.
Reactive programming remains dominant in high-throughput systems, offering event-driven architectures and backpressure handling.
Other languages like Go, Rust, and C# have their own concurrency models with unique strengths and complexities.
Coroutines are unlikely to become obsolete in the short term due to Android's Kotlin-first push and structured concurrency.
Coroutines' design philosophy ensures their relevance, providing a balance of power and simplicity for diverse development needs.
While challenges like debugging and competition from Project Loom exist, coroutines are expected to stay significant for the foreseeable future.
Developers are encouraged to master coroutines while staying informed about emerging concurrency technologies.
The landscape of concurrency is evolving, but Kotlin coroutines remain a valuable tool for various application development scenarios.

SSH Keys Don’t Scale. SSH Certificates Do.

Most teams traditionally use SSH public key authentication which becomes unscalable with more users and hosts, leading to operational and security risks.
SSH certificate-based authentication offers a more scalable approach and is already used by companies like Meta, Uber, and Google.
SSH key management sprawl, unclear access boundaries, and maintenance challenges arise with traditional SSH key authentication.
SSH certificates enable a centralized, auditable, and secure SSH access model with short-lived credentials.
Setting up SSH certificates requires initial engineering effort but simplifies user access management to hosts.
SSH certificate-based authentication relies on CA-signed certificates for users and hosts, forming a mutual trust model.
Users are configured to trust host certificates, and hosts only allow access to users with valid certificates.
Infisical SSH offers a solution to abstract the complexity of setting up SSH certificate-based access for teams and infrastructure.
Infisical SSH simplifies the setup process by handling CA management, trust configuration, and SSH certificate issuance.
Users can register on Infisical SSH to establish secure SSH certificate-based connections with hosts.
