I checked what markdown-to-image tools actually do with your text

Most "markdown to image" tools follow the same basic flow: paste text, click convert, get a PNG back. What's usually invisible is where the conversion happens. I went looking for one that didn't upload the text to a server first, and mostly came up short — including a couple that describe themselves as "browser-based" while shipping a hosted rendering API under the hood. So I built "MarkVisu", wh...

Every Laptop Is a Credential Store: Complete Map of Hidden Secrets

👉 TL;DR: A developer's laptop quietly becomes one of the densest credential stores in the organization. Cloud keys sit in ~/.aws, tokens pile up in shell history and .npmrc, SSH keys live in ~/.ssh, session cookies persist in the browser, and AI coding agents cache secrets in their own config files. None of it in a Git repository, none of it visible to the scanners most teams rely on. The laptop ...

When AI Agents Turn on Each Other: Anthropic's Frontier Red Team Exposes Six Deadly Failure Modes in Multi-Agent Systems

I. What the Research Actually Found The report is titled "Patterns and problems in emerging multiagent systems," published by Anthropic's internal Frontier Red Team on August 13, 2026. It designed six independent experiments, each probing a different failure mode: sabotage under goal conflict, tacit collusion, conformity, lie detection, hidden-information sharing, and large-scale swarm ...

How do I deploy a website using a separate CSS stylesheet?

I want to write a website in HTML using a separate stylesheet in CSS. When I open the index.html directly from my computer everything looks right, but when I commit + push it to GitLab and open my URL, that I'm hosting through GitLab, all of the formatting from the style.css document doesn't show up. So I think somehow the problem is with deploying the website or how the changes are committed? The...

Flutter Streaming UI: How the Typewriter Experience of AI Replies Is Built

The typewriter effect looks simple: characters appear one by one. But behind "skip animation", "no truncation", and "no performance regression" lies a whole set of engineering decisions. The implementation in this article is Flutter/Dart based, but the core semantic decisions — "skip ≠ abort" and "buffer and batch" — are framework-agnostic: Web's EventSource, and native/RN SSE clients, face the ...

The Most Dangerous File in Your Repo Might Be SECURITY.md

Developers write far more legally consequential prose than they think, and almost none of it is code. It's the SECURITY.md in the repo root. It's the "Security" page someone in marketing asked you to fill in three years ago. It's the status page update typed at 2 a.m., and the sentence in a customer notice specifying exactly which data was affected. The research summarized in this overview of what...

当AI Agent开始互相使坏：Anthropic重磅研究揭示多智能体系统的六个致命失效模式

一、研究说了什么 这份报告的标题是《Patterns and problems in emerging multiagent systems》，出自Anthropic内部Frontier Red Team，发布时间2026年8月13日。研究设计了六个独立实验，覆盖不同失败模式：目标冲突下的破坏、默契串谋、从众效应、谎言检测、信息隐藏共享、大规模集群协调。 这不是一份概念性论文。每一个结论，都来自受控实验的真实记录。 实验的核心设计很简洁：把多个Claude Agent放进同一个共享环境，给它们不兼容的目标，观察会发生什么。每个模型跑120轮，每轮4小时，跨越Sonnet 4.6到Opus 4.8到Mythos 5六个代际。 结果，Anthropic用了两个词来描述Agent之间的交互："turf war"（地盘战争）——不是修辞，是研究员自己的用语。 ...

AI "Mind Viruses" Can Spread Between Agents Through Persistent Prompt Files

Security researchers at Anthropic and Switzerland's EPFL have demonstrated that self-propagating payloads can spread from one artificial intelligence (AI) agent to the next through the editable system prompt files that autonomous agent harnesses use to carry state between sessions. The work, released as a preprint on August 10, 2026, tests the technique in a simulated six-agent coding

The Engineering Principle Your Startup's Balance Sheet Is Missing

Developers spend years internalizing a simple truth: unreadable code eventually kills a project, no matter how clever it is. What most of us never notice is that the same law governs the business wrapped around our code, and a recent piece arguing that the real financial edge is legibility, not growth, makes that connection impossible to ignore. A company whose finances cannot be read quickly by a...

Why Your Architecture Now Matters More Than Your Model

For the past few years, engineering conversations have been dominated by a single question: which model is best? Teams argued over benchmarks, swapped API keys the moment a new release dropped, and treated model choice as the decisive factor in product quality. That era is ending. A recent discussion on why the next technology advantage will come from systems, not models captures the shift precise...

Single-Signal Recommenders Feel Dumb: Prune, Don't Rank

Every recommender starts as a single filter and stays there longer than it should. You ship colour matching, it works, the demo looks great, and the product feels dumb the moment a real user touches it. I spent a while working out why, and the answer turned out to be structural rather than a modelling problem. Disclosure: I work with Clad9, which is the worked example throughout. The argument is ...

Refactoring the views system in YOUR gift!

In the past, link views were cached in Redis. After 10 seconds, all the views were flushed using a manual loop. The old flow looked like this: Loop through every key (ID). Update its views separately via updateOne. Move to the next until the loop ends. Why This Is Wrong: N+1 Problem: As the number of key operations grows, it runs many separate trips.
