Before running an A/B test, work out one number — for most Vietnamese sites it exceeds a year of traffic

You do not have to run an A/B test to find out whether it can conclude anything. One calculation, about a minute's work, gives the minimum number of visitors required. For a site with 500 visitors a day, detecting a 10% improvement needs 322 days — and the habit of checking results daily pushes the false-win rate from 4% to 20%.

GPT-6 Astra: skip the AGI claim, these three numbers are the ones that matter

On 3 September OpenAI released GPT-6 Astra, and the company's president said it might come to be seen as AGI. For anyone who has to make a decision, that sentence is close to unusable. Three other numbers from the same day are not: a risk rating no model had reached before, a 37-point gap on the same test, and a price 2.5 times higher.

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.

When cloud prices stop falling: 'ship now, optimise later' just expired

On 4 January 2026, AWS quietly raised H200 GPU prices by 15% — ending two decades in which compute prices moved in one direction only. That does more than make the bill larger. It breaks the unspoken assumption that has bailed out every wasteful architecture for fifteen years: ship it, prices will fall.

The dashboard was delivered and nobody opens it: the tool is not the problem

A company pays for a reporting screen, the handover goes well, and three months later nobody opens it. The first instinct is to blame the software, or to blame staff for not being comfortable with numbers. One figure shows both explanations miss: inside the same company, executives use it around 80% while employees use it around 26% — same software, same data, same screen.

Vietnam's Personal Data Protection Law: the legal text takes an afternoon, the engineering takes months

Law 91/2025/QH15 took effect on 1 January 2026 alongside Decree 356/2025/NĐ-CP. Reading both takes an afternoon, but the real obligations reduce to three architectural questions — and most operating businesses cannot answer the first one: what personal data are you holding, and where?

AI agents for the enterprise: reliability multiplies, it doesn't add

Gartner predicts more than 40% of agentic AI projects will be cancelled before the end of 2027. The cause usually isn't model quality: a 20-step agent that is 95% reliable per step completes the whole run only 35.8% of the time — and that's arithmetic to do before committing budget, not after.

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.

Claude Opus 5: the real cost is token consumption, not the sticker price

Anthropic released Claude Opus 5 on July 24, 2026 at an unchanged $5/$25 per million tokens — half the price of Fable 5 — and per Artificial Analysis it now scores highest on their intelligence index. But for an engineering team, the number that matters more than the sticker price is how many tokens the model actually consumes, and the effort parameter is what governs that.

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.

China's GIS technology leads Asia: the concrete evidence, and why 'surpassing Japan' needs a closer look

China now holds 34.2% of the Asia-Pacific GIS market — the largest share in the region, ahead of Japan — with SuperMap leading software and Jilin-1/Gaofen leading commercial remote-sensing satellites. But "surpassing Japan" needs qualification: Japan still leads in micro-SAR satellites and HD autonomous-driving maps, and some direct comparisons simply don't exist in real sources.

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.
