Pains

Creating training loops in TensorFlow is considered unintuitive and difficult to figure out, reducing developer productivity and increasing the learning curve especially for those coming from simpler frameworks.

Despite improvements with async/await syntax, JavaScript's asynchronous programming model remains confusing for developers, especially beginners trying to understand callback ordering, promise chains, and error handling in complex scenarios.

C++ lacks standard types for basic data structures like strings, arrays, and lists, or has multiple competing standards and non-standard implementations. Each interface works with different string/container variants, making code reuse difficult and forcing runtime type conversions, reducing performance and maintainability.

Tauri cannot properly create macOS universal binaries from separate arm64 and x64 builds, and performs redundant codesigning on macOS builds. While not hard blockers, these issues are annoying enough to delay migration decisions.

AWS does not communicate when services will be ready or whether specific requirements will be supported. Features evolve unpredictably, and if AWS doesn't add needed functionality within required timeframes, developers must compose workaround services.

Pointer tagging—packing additional data into unused pointer bits—lacks universal portability across systems. Developers struggle to verify whether certain pointer bits are actually unused on a given target system, limiting practical application despite hardware design opportunities.

STL implementations excessively inline code and ignore custom allocator type members, limiting optimization opportunities and making memory management customization ineffective in performance-critical scenarios.

Tauri's long-term success depends on the growth of official and community plugin repositories; insufficient plugin availability limits access to native functionality developers need.

Developers frequently forget to properly close SQLite database connections, leading to memory leaks and performance degradation over time. This requires developers to implement proper connection lifecycle management patterns.

Tauri apps consume significantly more resources than native applications (10x worse in some metrics), still requiring manual closure to avoid system sluggishness, limiting its lightweight promise.

While Electron provides true cross-platform consistency by bundling Chromium, alternatives like Tauri rely on system WebViews that vary significantly across OS versions (particularly problematic on Linux), creating debugging challenges. Tauri's approach yields much smaller binaries (10-20MB vs 50-90MB).

Opening files and loading large C++ projects is slow, and navigation between header and source files is cumbersome, causing delays during development.

Different browsers interpret JavaScript code slightly differently, causing inconsistencies in rendering and functionality across platforms, requiring additional testing and workarounds.

The responsibilities and relationships between Builder, App, Window, and Runtime objects, along with their proxy and handler types, lack clarity in the codebase, making it difficult for developers to understand how to properly use the API.

The condition variable implementation in the standard library is plagued by spurious wake-ups and has unnecessarily complicated syntax compared to other languages.

Snap packages are slower to launch, consume more disk space, and create additional mount points, contributing to system bloat. They represent a departure from the Unix philosophy of small, efficient programs.

Canonical aggressively promotes Ubuntu Pro subscriptions through MOTD messages, apt output, and website navigation, with ads appearing in the Apps menu. This commercial behavior alienates users and contradicts FLOSS principles.

Unnecessary or redundant dependencies lead to bloated codebases, increased resource consumption, and performance issues. Managing bloat requires regular audits and optimizations.

String manipulation in C++ is cumbersome and lacks convenience functions. UTF-8 support is only now emerging in the standard library after years of using workarounds.

Redis uses a gossip protocol and majority voting for failure detection instead of formal consensus algorithms like Raft or Paxos, reducing implementation complexity but increasing latency during failover operations.

Ubuntu ships with many pre-installed applications and tools that create system bloat. What was once a minimal install is now heavy, leading to slower overall performance and loss of Ubuntu's identity.

Ubuntu's design decisions sometimes force users down specific paths rather than empowering them. The shift toward a more controlled environment limits freedom and flexibility that Linux traditionally offered.

There is no standardized way to structure multithreaded code in C++, leaving developers to create bespoke solutions.

Many developers perceive Next.js as overengineered, adding unnecessary complexity without proportional benefits. The framework's architectural decisions and accumulated features create bloat that doesn't serve most use cases.
