Action Wheel: a radial menu for Windows — one middle click puts your everyday actions right under the cursor

Action Wheel is KonexForge's open-source (MIT) app for Windows 10 and 11: middle-click anywhere and a ring of 9 buttons appears around the cursor to send a shortcut, launch an app, run a Windows function, or open an AI tool such as Claude Code or Codex. This post covers how it works, how we designed the AI features to be safe, privacy, and how to install it in a few minutes.

PHP2Shell and Node2Shell: flaws that are neither new nor old, and why the patch is only the start

On 21 October 2026, PHP and Node.js both shipped emergency fixes for remote code execution flaws in their core — PHP2Shell (CVE-2026-109618, CVE-2026-109619) and Node2Shell (CVE-2026-111497). Both were found with the help of AI, in code that had been sitting there for years. This post sums up what happened, why updating one server does not mean you are patched, and a checklist for businesses running PHP or Node.js.

How many tokens does Vietnamese cost? Measured on six tokenizers — plus a formatting issue that multiplies the AI bill by two and a half

"Using AI in Vietnamese costs more than in English" is true, but how much more depends on the model. We measured eight bilingual business texts on six public tokenizers: with newer tokenizers, Vietnamese costs about 1.2–1.4 times as many tokens; with older ones, about 2.1–2.3 times. Typing without diacritics saves nothing on newer tokenizers — it costs more. And if Vietnamese text is stored in decomposed Unicode form (NFD), the token count can rise nearly 2.5 times, fixable with one line of code.

Vibe coding: building an app in a weekend is real — and so are the five problems that come with it

Vibe coding — describing what you want, letting AI write all the code and not reading it — lets people who cannot program build working apps in hours. But Veracode's research found 45% of AI-written code samples failed security testing, nearly one in five libraries AI suggests does not exist, and one common misconfiguration exposed the data of 170 apps. This piece separates when vibe coding is worth using from when it is not, with six self-checks before an AI-built app goes live.

Forge Dialog: dialogs built on the native <dialog> element, with no z-index left to hunt

An admin page needs to ask "are you sure you want to delete this?". The browser's built-in confirm can do it, but it freezes the whole page and cannot be styled; the usual replacements drag in a framework. Forge Dialog is how we solved that for our own products: no runtime dependencies, built on the native dialog element, with React, Vue and Svelte adapters inside the same package.

Accessibility for business websites: why 83.9% of home pages still fail the easiest criterion

The WebAIM Million 2026 report found low-contrast text on 83.9% of home pages — the single easiest WCAG criterion to check by machine — and the six most common failures haven't changed in seven years. This isn't a knowledge problem. It's a measurement problem.

Technology solutions for private clinics and doctors: from e-invoicing to electronic medical records

Within an 18-month window, Vietnam's private clinics and independent doctors face three new compliance obligations at once: e-invoicing under Decree 70/2025, the end of presumptive tax from Jan 1, 2026, and a Dec 31, 2026 deadline for electronic medical records under Circular 13/2025/TT-BYT — while most still run on paper logs, Excel, and Zalo. The minimal-footprint architecture we propose, and why a scaled-down hospital system isn't the answer.

Why digital transformation leads to 5-6 disconnected systems and data duplicated everywhere

Many companies and government agencies don't lack technology — they have too many systems. After a few years of piecemeal digital transformation, an organization typically ends up running 5-6 systems that don't talk to each other, with the same customer or employee existing under several different data versions. This post breaks down why that happens and the consolidation architecture KonexForge applies to fix it — not by buying a seventh system.

Forge Select: a zero-dependency, framework-agnostic open-source replacement for Select2

Select2 has served the web community for years, but it's built on jQuery — a dependency that's increasingly hard to justify on a modern stack. Forge Select is the select/combobox component we built ourselves: a 5-file core, zero runtime dependencies, yet full-featured enough for real products — virtual scroll, tree select, tags, and full accessibility.

ERP Ecosystem One: a unified platform for small businesses and one-person companies in the AI era

AI now lets one person do work that used to require a whole team — but it also leaves that person juggling 8-10 disconnected SaaS tools: accounting, CRM, inventory, e-invoicing. ERP Ecosystem One is KonexForge's answer — a unified platform designed from the ground up for a team of one, not a scaled-down enterprise ERP.

KonexForge Themes: a VS Code theme family with a 'forge' aesthetic — not another One Dark clone

Engineers stare at their editor all day, yet the VS Code theme market is saturated with variants that look nearly identical to One Dark Pro. KonexForge Themes is the open-source set of 4 themes we built ourselves — not to sell, but because a distinct visual identity is part of engineering culture too.

E-invoicing for micro household businesses: what works for a banh mi cart or a street noodle vendor?

From January 1, 2026, Vietnam's flat-rate presumptive tax for household businesses is fully abolished — every household business, down to a single street food cart, must now self-declare based on actual revenue. But the e-invoicing solution built for restaurants or taxi fleets can't be dropped straight onto a vendor who's cooking and making change with the same two hands. Three real-world constraints and the lean, low-cost architecture we propose.
