Bash history does a lot more than scroll up. Learn how to configure HISTSIZE, timestamps, multi-terminal sync, and search shortcuts to get real productivity gains at the command line.Continue reading...
Atomic Object Raleigh has several ongoing projects, all of which involve varying degrees of AI-assisted coding, as well as some creating agentic applications. Recently I asked other engineers in our office to share their thoughts on Model Context Protocol (MCP) Servers. MCP is a standard that lets AI tools connect to third-party systems (such as […] The post Atomic Object on AI: MCP Servers appeared first on Atomic Spin.
Learn how to tune Linux kernel parameters using sysctl and /proc/sys for better network throughput, memory management, file I/O, and server security. Includes a ready-to-use baseline config.Continue reading...
The /proc filesystem is a live window into the Linux kernel: process state, memory layout, CPU counters, network stats, and writable kernel tunables, all accessible with nothing but cat and grep. This guide walks through the most useful files and per-process directories with practical examples.Continue reading...
Something is happening in server-rendered web development. React shipped Server Components. HTMX made “hypermedia” cool again. Phoenix LiveView proved a server can push interactive UI updates without a client framework in sight. Every ecosystem seems to be rediscovering the server as a place to render UI, except one: the JVM. What if Compose, the UI […]
A practical guide to DNS resolution on Linux: how /etc/resolv.conf, systemd-resolved, and dig work together, and how to troubleshoot common nameserver failures.Continue reading...
Password-based SSH login is a liability. This guide walks through generating SSH key pairs with ssh-keygen, deploying public keys, disabling password authentication, and managing multiple keys cleanly with ~/.ssh/config.Continue reading...
The nc command (netcat) is a lightweight but surprisingly powerful networking tool for port testing, file transfers, banner grabbing, and connectivity debugging. This practical guide covers the flags and real-world usage patterns that Linux users and sysadmins actually reach for.Continue reading...
Servers give you warnings before they fail. Most sysadmins performing Linux server monitoring miss them because they're watching the wrong numbers. The metrics that actually matter are one level deeper: iowait instead of CPU percentage, active swap paging instead of memory usage, inode counts instead of just disk space.Continue reading...
The watch command runs any Linux command repeatedly at a set interval and displays the output full-screen, making it one of the quickest ways to monitor live system activity without writing a script. This guide covers all the key options with practical examples for real sysadmin use cases.Continue reading...
I’ll admit, I hesitated a bit before writing this post. The whole point of this linuxblog.io and linuxcommunity.io forum is to bring together like-minded Linux users and professionals so we can troubleshoot, share ideas, and learn from one another.Continue reading...
tmpfs lets you mount a filesystem entirely in RAM. Here is how Linux already uses it, how to create your own mounts, and where it actually makes sense to use one.Continue reading...
A practical guide to Linux user and group management using useradd, usermod, userdel, groupadd, gpasswd, and chage. Covers real-world examples, common mistakes, service accounts, and safe account removal.Continue reading...
This post explains how to install Dropbox command line client on a Linux server, create a dedicated user and setup it as a service to have automated backups on Dropbox cloud.
