The Newspaper of One: Inside a Lights-Out Publishing System
For most of publishing history, the bottleneck was production. Type had to be set, pages had to be laid out, presses had to roll, and every word of copy had to pass through a chain of human hands. The economics of media were rea... read more
Why "sent" isn't "delivered": tracking transactional email in Node.js with webhooks
Sendaro |
A user clicks "Forgot password", your API returns 200, and ten minutes later they open a support ticket: the email never came. You check your logs and find email sent successfully. So what happened?
Usually the answer is that "sent" only ever meant "some server accepted my request". Getting that e... read more
I build YuHex in C/C++ and YuGPT in C#. One reason? I wanted conditional compilation. #ifdef in C/C++, #if in C#. There's a practical reason why this matters to me as an indie developer. Can you guess what it is?

Rebuilding the Salesforce trigger framework as a baseline
Aamir Khan |
Every Salesforce project I have worked on eventually grows a trigger framework. It starts as a single trigger with an if statement, becomes an interface with a dispatcher, and ends with a static Set<Id> that someone is afraid to touch. The code is rarely the problem.

Valve: We Still Believe in VR, But Content is Still ‘Chicken-and-Egg’ Dilemma

Valve says VR's problem is "chicken-and-egg" content. Structural biology has the opposite problem — a decade of 3D data trapped on 2D screens.
Road to VR covered Valve's comments out of a Steam Indie Connect event in Korea: they still believe in VR, but content remains the bottleneck. I ... read more
Release notes from git log, without a changelog tool
Robin Beraud-Sudreau |
Writing release notes by scrolling through git log is slow and easy to get wrong. You skip a fix, you forget which change breaks users, and the notes end up as a raw list of commit hashes.
I wrote a small Hermes skill, changelog-from-git, that does the boring part. It is one Python file using only... read more
How AI search answers work — and why they sometimes invent facts
Faizan Altaf |
You ask an AI search tool a question. It answers in a second, in clean paragraphs, with confidence. Sometimes the answer is excellent. Sometimes it invents a date, a name or a reference that never existed — and says it with the same confidence.
