I Automated 90% of The Ethers.js v5 v6 Migration using Codemods and AI

Ethers v6 dropped a breaking change on every project that touched BigNumber, utils, or providers — which is basically every DeFi frontend ever written. The migration guide listed over 40 breaking changes. Some were simple renames. Some required understanding whether a variable was a BigNumber before deciding what to do with it. Doing this by hand across 31 files is exactly the kind of work that ma...

Quantum Computers Are Coming for Web3 Identity

By Malak Gandhi | BTech CS (AI & ML), ATLAS SkillTech University If you’ve spent any time in the tech world lately, you’ve probably heard two major buzzwords: Decentralized Identity (DID) and Quantum Computing. On one hand, Web3 enthusiasts are pushing for DID so we can finally own our digital identities instead of trusting centralized servers (which seem to get hacked every other week). On ...

Should Hand-Written Code Be Considered Art Now?

A few years ago, "writing code" meant sitting down and writing code with your own hands, kicking in a concentrated thinking process, being in a "flow". Today, more and more of it is generated, scaffolded, auto-completed, or delegated wholesale to AI. The act of typing out a function by hand has shifted pretty drastically from the default way of building software to delegating most of the code writ...

深度解构纽约时报视频流架构：如何构建基于 HLS 与 FFmpeg 的高性能提取引擎

引言 作为开发者，我们对大型平台如何在全球范围内管理和分发多媒体数据总是充满好奇。《纽约时报》（The New York Times）作为全球顶尖的新闻机构，其视频分发架构并非简单的文件托管，而是一套复杂的、基于 HLS (HTTP Live Streaming) 的动态自适应流媒体系统。 对于许多研究人员和开发者来说，存档 NYTimes 的高质量新闻视频具有极高的技术参考价值。然而，随着 DRM（数字版权管理）的加固和流媒体协议的碎片化，高效提取这些资源的门槛越来越高。为了应对这一挑战，我开发了 NYTimes 视频下载器。本文将揭秘其背后的工程实现：从 HLS 协议逆向、动态 Token 校验循环到服务端的无损混流（Lossless Muxing）。 1. 媒体分发协议的演进：从 MP4 到 HLS 早期的 Web 视频分发非常直接：通过...

Crossposting without the copy-paste: a GitHub Action from Hugo to dev.to

My blog runs on Hugo. I also recently discovered I can cross-post to dev.to, because that's where a lot of the conversation actually happens. For a while, my workflow was the obvious one: write the post, publish it here, open dev.to, paste it in, fix the frontmatter, fix the links, hit publish. It worked. I also stopped doing it after the second post. Copy-paste friction is the kind of chore tha...

Retrofitting Privacy: Adding Midnight to an Existing dApp Step by Step

Retrofitting Privacy: Adding Midnight to an Existing dApp Step by Step Last year I inherited a voting dApp that had been running in production for eight months.

Voter addresses, their choices, the exact timestamp of each vote — all of it sitt...

Pinning GitHub Actions to a tag is mass negligence and we all just watched it happen

Many of your CI pipelines can easily be manipulated to execute any code with a single force-push. And you likely unwittingly enabled this yourself. I certainly did. What Actually Happened In March 2026, LiteLLM was breached using a poisoned Trivy GitHub Action. The threat actor didn't publish a new, obviously-malicious action under a typo-squatted name. They force-pushed malicious cod...

The clock is ticking, and the nagging fear of missing a crucial piece of exculpatory evidence—your client’s Brady material—is real.

FHE programs have precision bugs random testing can't find — here's an adversarial search tool that does

FHE has a precision-testing problem, and random testing misses it If you compile an ML model to run under Fully Homomorphic Encryption, the encrypted and plaintext versions should give the same answer on every input. Under CKKS — the scheme most FHE ML deployments use — they usually do. But CKKS is approximate: noise accumulates across multiplications, and on specific inputs it can push...

Resurface Claude Code Usage Across Your Team with CloudWatch OTEL (No Lambda)

I've been building AI tooling infrastructure to empower a team of 50+ software engineers to do vibe coding safely. We went from 3 engineers using AI full-time to 50+ in 6 months — including non-engineers. (I co-presented on this journey at AgentCon Hong Kong 2026.) One thing we learned: you can't improve what you can't measure. Once you give a team AI coding tools, you want visibility into how th...

Why I Built an AI Visibility Tool When Semrush Already Had One

Why I Built an AI Visibility Tool When Semrush Already Had One Semrush shipped their GEO tool first. So did Otterly. So did half a dozen enterprise SEO suites.

Here's the honest answer: the existing tools are built for enterprise SEO agencies, not for individual merchants. I tried to use them ...
