Hyper-Cache The Future of Ultra-Fast Memory Beyond RAM
Introduction: Why Memory Has Become the Real Bottleneck For decades, the performance of computers improved mainly by making processors faster. Today, that approach no longer works on its own. CPUs, GPUs, and AI accelerators have become extremely powerful, but they are increasingly forced to wait for data. The real problem is memory. Traditional memory…

Kernel Locking and Concurrency Pitfalls in Operating Systems
In modern operating systems, concurrency isn’t optional — it’s fundamental. Multiple threads and processes access shared resources constantly: memory, I/O, scheduling queues, filesystem metadata. Without strict synchronization, the kernel becomes a war zone of race conditions, data corruption, and unpredictable crashes. The kernel sits at the lowest level of control. If a locking mistake…
