Every once in a while I get asked why I don’t have an out-of-office message for my email or voice mail. Truth is, I’ll often monitor my email even when I’m out, though I often practice good operations discipline by not responding. Just as intermittent problems with computer systems are hard to deal with, a […]

I’ve found that things that are free of charge are often not a good deal. TANSTAAFL, or “There ain’t no such thing as a free lunch.” You’re always paying in some way. Maybe the piece of hardware is marked up more to cover the development cost of the “free” software that comes with it. Perhaps […]

I was setting up VMware vRealize Automation’s Active Directory connections the other day and I needed the public SSL certificate for the AD DCs to authenticate correctly. You can use OpenSSL to get that information. I used a Linux shell but this should be do-able from a Mac or with OpenSSL installed on Windows, too. […]

I just got a new iPhone Xs Max. I had an iPhone 6s which I liked a lot, but it’s been a few years and with more travel I thought I’d enjoy having a better device with me. There are a few things that bit me in the duff. Some two-factor authentication (2FA) apps like […]

by George Whittaker Introduction Linux system administration encompasses managing the software and hardware of Linux systems, which can be complex, especially for those new to Linux or managing multiple systems. Fortunately, Webmin, a web-based interface, simplifies many of the routine tasks involved in maintaining a healthy Linux system. This article explores how Webmin can be […]

by Bryan Lunduke What is DevOps? How does it relate to other ideas and methodologies within software development? Linux Journal Deputy Editor and longtime software developer, Bryan Lunduke isn't entirely sure, so he asks some experts to help him better understand the DevOps phenomenon. The word DevOps confuses me. I'm not even sure confuses me […]

by Kyle Rankin Take a tour through the best infrastructure I ever built with stops in architecture, disaster recovery, configuration management, orchestration and security. Working at a startup has many pros and cons, but one of the main benefits over a traditional established company is that a startup often gives you an opportunity to build […]

by Andy Carlson How to provide robust monitoring to low-end systems. When running a critical system, it's necessary to know what resources the system is consuming, to be alerted when resource utilization reaches a specific level and to trend long-term performance. Zabbix and Nagios are two large-scale solutions that monitor, alert and trend system performance, […]

Attempts to turn the PHP2Shell vulnerabilities into Potassium botnet infections have not produced a confirmed compromise, despite the millions of attacks Cloudflare reported within hours of disclosure. The attackers tried to use CVE-2026-109618 and CVE-2026-109619 to install a Mirai-derived Linux botnet, but researchers have not seen the malware downloaded or executed through those attempts. PHP […]

Imperva researchers have demonstrated that Node2Shell (CVE-2026-111497) can execute code on an official, unmodified Node.js 24.22.0 image running Linux arm64. The exploit uses crafted Brotli data and took several attempts; Node.js 24.22.1 rejects the same input. Applications that decode attacker-controlled Brotli data should update to a fixed release.

The point of Zoom’s Unified Context Layer is to give AI business context it can use to help an individual participant during a conversation—not just transcribe what was said. In principle, an assistant could use that context to surface a relevant answer or suggestion. Zoom says its planned Live Meeting AI Agent will provide proactive […]

Microsoft fine-tuned the open-weight Qwen3.8-27B model for business tasks, using ThinkingBox-Training, an open-source system that rewards AI agents for leaving databases in the correct final state. The approach more than doubled the number of tasks Qwen completed correctly on all 20 attempts, though it solved slightly fewer tasks at least once. Source
