A disk error indicating a bad block points out to disk failure. It can happen to HDDs and SSDs and the damage could be hardware or software-related. You’ll notice ...

As we mentioned previously, disk request scheduling is non-work conserving and the optimal algorithm, which is also NP-complete, uses the positioning time rather than the seek time per request, when ...

This project implements and visualizes various disk scheduling algorithms using the analogy of elevators in a building. The primary algorithms include FCFS, SSTF, SCAN, LOOK, and their circular ...

This Jupyter Notebook (Disk-Scheduling- Simulation.ipynb) simulates and compares the performance of three disk scheduling algorithms: SCAN, C-SCAN, and C-LOOK.

There are many ways to evaluate disk space usage on Linux, and this post examines a number of commands that allow you to view used and available disk space. The df command stands for “disk free” and, ...

In this section, we describe how an in-disk scheduler must evolve to support range writes. We present two approaches. The first we call expand-and-cancel scheduling, a technique that is simple, ...

The looming challenges of quantum computing have prompted the Java Platform to implement two advanced cryptographic solutions in its upcoming release, Java 24, slated for March 2025. Quantum computers ...

A post shared on Threads claims musician Taylor Swift said, “Elon Musk, the first human in history to be radicalized by his own algorithm.” ...
