Things that are actually out there.
A running log of new articles, public applications, and improvements to the portfolio. Dates of availability checks are not necessarily original launch dates, and I don't invent release versions.
Network Design Studio is live with five working engineering calculators
A third independently deployed public application now covers IPv4, VLANs, PoE budgets, UPS runtime and camera-storage estimates under an isolated Cloudflare Worker.
What's included
- Twenty-seven deterministic calculation tests passed alongside mobile and desktop browser verification on both domain hostnames.
- Real product screenshots and an independent project case study are available in the portfolio.
- Genuine site/device specification inputs still matter: UPS and camera-retention figures are illustrative, not product guarantees.
Engineering analytics, VPN comparisons and six new practical guides
A new interactive engineering lab demonstrates measured text compression, a sortable VPN and zero-trust comparison grid, and safe AI-assisted operations patterns.
What's included
- Gzip and Brotli charts use reproducible build-time measurements of clearly labelled sample files.
- Six guides cover change windows, guest Wi-Fi troubleshooting, restore drills, IaC review, remote access and web compression.
- Source-linked comparisons and FAQs are educational; no private systems are connected or remotely controlled.
Three original field notes become fully illustrated technical guides
The first application, homelab and security/CI/CD articles have been rewritten with sourced technical walkthroughs, interactive explorers, diagrams and copyable examples.
What's included
- Application architecture now traces DNS, edge, application and data boundaries with practical diagnostics.
- Homelab planning covers isolation, virtual machines, storage replication and tested recovery.
- Secure delivery now explores review, build, identity, deployment and verification gates.
A practical first-response SOP for unreachable web services
A new incident-response guide includes a session-only interactive checklist, read-only diagnostic commands and clear guidance for communication, approval and verification.
What's included
- Six-step checklist for confirming impact, isolating the failing boundary and validating recovery.
- Sourced references include Google SRE and Cloudflare 5xx troubleshooting.
- Educational examples cannot execute commands or act on infrastructure.
Linux and VPS hardening: a staged, safer guide
A practical Ubuntu security guide now covers SSH, sudo, UFW, patching, AppArmor, monitoring and recovery—with customizable, copyable command examples.
What's included
- Interactive sample username, server address and SSH-port controls generate guarded command examples.
- Highlights lockout, firewall, sudo, networking and auditing risks in bulk hardening scripts.
- Includes step-by-step verification, rollback planning, source references and operator-friendly read-only aliases.
Networking, UniFi and communications now have a home
A dedicated services page now explains Wi-Fi deployments and optimization, self-hosted UniFi Network management, guest portals, cameras, access control and PBX/VoIP capabilities.
What's included
- Six clearly described areas include UniFi Network, Protect, Access and Talk, as well as 3CX and Grandstream.
- A practical discover–design–deploy–support overview, independent consultancy inquiry and careful platform compatibility notes.
- Future article topics are clearly marked as planned, not misrepresented as published work.
PHP2Shell explained: critical PHP runtime vulnerabilities
A sourced, detailed guide to the two PHP2Shell vulnerabilities, their patched runtime releases and what operators can do to assess and remediate exposure.
What's included
- CVE-2026-109618 and CVE-2026-109619 explained without exploit payloads.
- Affected and fixed PHP branches, defensive inventory commands and verification steps.
- Illustrated incident-response process, references, and a dedicated article sharing image.
An interactive automation workflow you can explore
A new article illustrates how an alert moves through validation, analysis, operator approval, a scoped action and verification, with an interactive read-only workflow canvas.
What's included
- Six selectable workflow nodes explain each stage and its safety checks.
- Python, Ansible, Terraform and OpenTofu roles are explained in context.
- Each node can be explored without running any real infrastructure action.
Infrastructure automation and IaC join the technology showcase
The technology ecosystem now includes Python, Ansible, Terraform and OpenTofu with their recognizable icons and accurate roles alongside the existing infrastructure and software interests.
What's included
- Ansible is presented as an automation and configuration-management tool.
- Terraform and OpenTofu are grouped as infrastructure-as-code platforms.
- The tooling list does not falsely imply the public apps were built with these technologies.
Real technology logos and responsive project previews
The portfolio now uses recognizable technology logos and real desktop/mobile views of the public applications instead of generic placeholder artwork.
What's included
- Locally hosted SVG icons for the technologies featured on the site.
- Desktop and mobile screenshot switchers for the two public apps.
- Mobile and dark-mode layout checks before release.
GYCalc — practical calculators for Guyana
GYCalc is a published collection of financial tools for local calculations and scenarios. This entry records that the app is available, not its original launch date.
What's included
- Pay and deduction scenarios, including PAYE and NIS.
- Vehicle-import cost estimates and loan comparisons.
- Dated assumptions and explanations alongside results.
Guyana Traffic Advisory — searchable road information
An independently published map and search tool for documented October 2026 restrictions. The app is live; road notices are not a verified real-time closures feed.
What's included
- Searchable reported restrictions and street information.
- Map and list views, with references to published notices.
- Prominent warning to follow police directions and posted signs.
