On cert-manager v1.21.2, a v1.18.6-issued rotationPolicy: Never CA renewed with the same key got a new SKI (SHA-1 → truncated SHA-256); OpenSSL accepted a pre-renewal leaf only with the old CA too.
Sammy Straus posted a side project to Hacker News, got about a hundred upvotes, and watched the site get slower for days. The culprit was not GPTBot or ClaudeBot. Nearly half of all traffic came from
Most applications eventually face login problems that have little to do with their core purpose. Users forget passwords, reuse credentials, and struggle with account recovery. Meanwhile, developers m
Day 14 of 30 Days of Search Attention Is All You Need reports experiments on two machine-translation tasks. A research agent preparing a literature review could cite it for a much broader statement:
Most teams that adopted AI coding agents expected one thing: ship faster. A new Harvard working paper on 718 companies suggests they got the opposite of the metric that matters. Code volume rose about
I've spent years delivering technical projects, and I keep running into the same thing: when a concept fails to land, it's rarely because the diagram was bad. It's because the metaphor was wrong. Her
TL;DR — Kafka/Flink pipelines are built around record-at-a-time, backpressure-aware processing, while model servers get their throughput from batching requests together. The seam between the two is w
Most programming articles teach one concept well and then stop. Real engineering work rarely looks like that. Developers need end-to-end problem solving, the ability to take a messy requirement from a
I've spent much of the last few months designing and building Public Voice, a new independent discussion forum. I'm a graphic designer first and a developer second, and one of the things I've enjoyed
You ship a new version on a quiet Tuesday afternoon. kubectl rollout status reports success, every pod is Running and Ready, and the dashboards look fine. Then someone notices a small spike of 502s in

Há tarefas que chegam para a gente com aquela aparência inocente de: "É só adicionar um card na tela." Foi exatamente assim que começou um dos cases mais interessantes que vivi trabalhando como
Computer vision is the technology that teaches computers to understand pictures and videos. Look at a photo of a coffee cup and you know right away what it is. You may even guess the coffee is hot. A
A surprising share of digital-download support pain starts with a simple mismatch: the person who paid is not the person who will use the file. A partner buys a template pack as a gift. An office mana
I ship an app on Kotlin Multiplatform, and when I counted the lines, the shared Kotlin code turned out to be just 14% of the codebase. So here's the question I keep asking myself as an iOS developer:
Most developers learn to code by following tutorials. They build a to-do app, clone a weather dashboard, or work through a bootcamp capstone. These exercises are useful at the start, but they rarely r
RustFS S3 Tables is an Apache Iceberg REST Catalog built directly into the RustFS object storage kernel, so one process on one port serves both standard S3 and the Iceberg REST Catalog protocol. That
Your webhook signature check fails, and the secret looks right. We list the causes in the order you're likely to hit them, from the raw body and hex vs base64 to clock skew and proxies, plus a step-by
TL;DR — Most RAG systems bake access control into the vector index at embedding time, treating permissions like content freshness. But permissions and content decay on completely different timescales
An .eml file is a saved email. Open one and you get raw MIME: headers, a plain-text part, an HTML part, maybe some base64 attachments. The HTML part is the interesting one, because it was written by w
