CyberGizmo: My Purpose and Ethics

At CyberGizmo, I aim to give back to the community by sharing my knowledge on Linux, open source software, and related technology. I provide tutorials, insights, and in-depth reviews of Linux distributions, kernels, and other tools to help users make informed decisions.

I prioritize honesty, transparency, and unbiased content. My reviews are based on personal experiences, and I maintain full editorial independence. While I do occasionally work directly with brands, sponsorships never influence my opinions.

I value open dialogue and am committed to engaging respectfully with my audience. Thank you for supporting my mission to deliver high-quality, reliable content.

Test environment (IMPORTANT):
• Benchmarks performed in a VM on **Proxmox VE 9.0.11**  
• Host: **Intel NUC12WSHi5**  
• Note: Virtualization can impact I/O, graphics, and latency; results are **not 1:1 comparable** with bare-metal. Where relevant, I call this out and focus on relative behavior, not bragging rights.

On the night of October 19th, 2025, just past the eleventh hour, something strange crept through the wires of Amazon’s vast cloud.
Alexa’s voice changed. Orders failed. The web trembled.

This is the true-to-life account of the US-EAST-1 outage that rippled through the Internet — how it began with DNS resolution failures in DynamoDB, cascaded across AWS services, and even brought down its own failover in US-WEST-1.

We’ll explore how a few milliseconds of latency turned into a retry storm that nearly broke the modern cloud — and why this might be a warning for the future of centralized computing.

🎙 Narration in the style of Washington Irving — with a touch of HAL 9000.
My Linux systems started acting strange — high load, lagging terminals, and memory in use with no owner.

Auditd was flooding logs, rsyslogd was melting down, and even bpftool showed dozens of eBPF programs running silently under PID 1, UID 0..

CYVS is a diagnostic script for the modern Linux era, built for transparency, detection, and truth.

Supports: 
Debian 13
Devuan 5 
Pop!_OS 22,.04 
Ubuntu 25.10
Arch
Alpine

Uses: Syft + Grype for SBOM + CVE analysis

You will need two other packages bpftools and jq

Ubuntu turns 21 — and its journey continues among the stars.
Ubuntu 25.10 brings GNOME 49, kernel 6.17, and a firm step into the Wayland era.
Some say Ubuntu has lost its compass — I say it’s still plotting by the stars.

In this review, we’ll explore what’s truly changed:
the rise of SELinux, the quiet growth of systemd, the shift away from X11,
and the deeper question — who really controls your Linux now?

For 21 years, Ubuntu has been on a quest —
and whether we agree with its path or not, we’re all still travelers under the same sky.

NVIDIA and OpenAI are talking about building a 10 Gigawatt AI data center — a project so massive it would consume as much electricity as an entire country like Switzerland or Belgium.

But is it actually possible? In this video, DJ and HAL break down the math:
 • How much coal, nuclear fuel, solar, wind, and tidal power would be required
 • The logistics of delivering fuel and handling cooling at this scale
 • Why even backup systems (UPS) run into walls of practicality

We’ll also ask the bigger question: Do we even need AI factories this large, or is this just corporate vanity?

 Part 2 will explore whether 10 GW AI factories are truly necessary — and how they might work at 33% less cost if approached differently.
Comment below if you want me to make Part 2!

Nvidia shocked the industry by buying a 4% stake in Intel. On paper, it looks like a simple hedge — Nvidia securing fab options while Intel fights to stay relevant. But dig deeper, and the picture gets stranger.
 • Intel is struggling to ramp its 20A/18A nodes and needs customers to justify massive fab spending.
 • Nvidia is already building CPUs, putting it right on Intel’s turf.
 • AMD risks being stranded as x86 faces new pressure from ARM.
 • AI demand looks unstoppable, but cracks are appearing as clouds pivot from “expansion” to “optimization.”
 • And the power paradox looms: Blackwell racks are pulling megawatts, while governments green-light datacenters but ignore the need for new power plants.

Is Intel becoming Nvidia’s foundry? Or is this the last gasp of two rivals forced into an uneasy alliance? Let’s break it down.

Windows 10 reaches end of support on October 14, 2025. Last year, I outlined five possible options for users. This year, I’ve updated the list to six — because so many people asked about Windows 10 LTSC.

In this video, I cover:
 • The real risks of doing nothing
 • The temporary ESU extension for one year
 • Why LTSC is the wrong tool for home PCs (and Microsoft says so too)
 • Whether ChromeOS Flex is a fit
 • Why Linux could be a permanent alternative
 • And why upgrading to Windows 11 might be your safest bet

Note: I will not recommend hacks, piracy, or violating license agreements. Don’t ask — comments like that will be deleted.

Official Microsoft LTSC guidance: https://techcommunity.microsoft.com/blog/windows-itpro-blog/ltsc-what-is-it-and-when-should-it-be-used/293181

Chapters
00:00 - Intro
01:09 - Options 1: Do Nothing
03:30 - Option 2: Microsoft ESU
06:31 - 3. Install Windows 10 LTSC
10:47 - 4: Google ChromeOS Flex
11:50 - 5. Linux
14:31 - 6. Move to Windows 11
19:16 - Final Thoughts
A custom written pipeline workflow piloting  NVMe drives through IOzone benchmarks on Ext4, XFS, Btrfs, Bcachefs, and ZFS..

The results?  NVMe drives with eark controls died in the process (2 of them burned up) 
Btrfs off the charts, and Bcachefs big improvement over last time.

Don’t try this at home — we’re professionals.
