In this article, you will learn how to choose the right chunking strategy for a retrieval-augmented generation system by working through a structured decision tree...

Last week I wrote about how we stop an AI agent from paying twice when it retries a paid API call . It got 309 views and 73 comments from 11 people, and most of the comments found a real gap. This is the follow-up: what each gap was, what we changed,

Measuring AI model security gets complex fast - a growing patchwork of benchmarks targets different variables in the equation, but none replace testing against your own code and workflows.

The v0.2.0 field test for agentwatch ran 94 cases across 15 suites. 92 passed. 0 failed. It was the least trustworthy green I'd ever shipped. Not because anything was failing - because I couldn't say why it was passing. So I did a census. Of the 94 c

視覚皮質を再学習させるVRアーキテクチャ：AmblyoPunchの設計思想 最近、SanDiskがMetaの次世代VRグラス向けに公式の拡張ストレージを提供することが発表されました。スタンドアロン型ヘッドセットにおけるI/Oおよびストレージ容量の制限は、これまで高負荷なシミュレーションや詳細なユーザーログを伴う専門的アプリの展開において大きな壁となっていました。このハードウェア的な制約の解消は、リハビリテーションや教育といった「専門的トレーニング」のあり方を根本から変える可能性があります。 1.

Less than two weeks after its $11,000 headline, the configurable deep learning workstation has dropped every Nvidia option and the tinybox pro, added two Radeon AI Pro R9700 builds, and raised their price.

I've been building a predictive coding (PC) engine from scratch in C++20, with a thin Python layer on top, and just cut the first public release. Posting here for feedback and because I haven't seen many from-scratch PC implementations with real kern

AI is scaling faster than almost any technology before it. But behind every intelligent response lies a costly infrastructure, an uncertain business model, and a question every developer should be asking: Who can afford to build the future? Artificia

If you have written concurrent code with threads, you know the routine. Several threads touch the same data, so you put a lock around it. Then you add a second lock, take the two in the wrong order on a busy day, and two threads wait for each other f

TL;DR - Teams treat SFT, preference optimization, and distillation as swappable, independently-testable modules in a post-training pipeline. They aren't. The order you apply them changes the final model in ways that per-step evaluation never catches,

A web page can save an AGENTS.md into your Downloads folder without a single click. Your coding agent reads it as project rules. Here's what happened, what we saw in our own test, and the 2-minute check. Your Downloads folder is the only folder on yo

While everyone watched LiteLLM, a quieter campaign spent five weeks doing something worse: taking stolen GitHub tokens and committing a secret-dumping workflow into every repository they could reach - 13,500 planted branches across 850+ compromised a

This is a submission for the Hacktoberfest Open-Source AI Challenge: Slow and Steady . What I built If you develop with Flutter, you may know the frustration of spending half an hour debugging an error, fixing it, and then meeting the same problem ag

My first real PayPal invoice was for $200. I knew PayPal "takes about 3%", so I expected roughly $194. I got $192.53. That's $7.47 gone, not $6. It isn't a huge amount, but I couldn't explain it, and that bothered me more than the money. Where the $7

Phone galleries, family archives, a photographer's backlog: where are all the photos of this person? Here is how to group photos by face in Python: detect every face, match it in a face repository, and sort the library into one album per person. No m

Local agents are finally growing up. In the past year we’ve seen a wave of sophisticated harnesses - Hermes, Pi, Ghostyy, OpenClaw, Claude Code-style systems - all trying to give models a persistent sense of self. Most of them still scatter identity,

This note has an interactive demo. Try it in the original You change the DOM however you like, wrap that change in document.startViewTransition() , and the browser animates from the old state to the new one. No FLIP math, no animation library, no kee

I started Toolgrain while building Pushwing and experimenting with Elysia for an MCP integration. I wanted a TypeScript workflow where I could define a tool independently, get useful types from its input and output schemas, and reuse that definition

Laziness is not a religion.

In this article, you will learn what Python descriptors are and how to use them to build three types of controlled attributes: validated, computed, and...

Run this on a typical laptop and both systems will report latencies in the low single-digit to tens of milliseconds range, with the exact numbers depending heavily on your CPU, available RAM, and whatever else is running on your machine at the time.

On 21 October, PHP shipped emergency releases for PHP2Shell : CVE-2026-109618 and CVE-2026-109619 . Unauthenticated remote code execution, every branch from 5.4 to 8.5.11, fixed in 8.5.12, 8.4.27, 8.3.36 and 8.2.35. CISA added both to its exploited l

Preparing for an Apigee Developer interview? The DecodeJWT policy is used to decode a JSON Web Token (JWT) and extract its header and payload claims into Apigee flow variables. It is useful when you need to inspect information such as a user's identi

As a developer, I always thought major security scares only happened to big tech companies. Then, it happened to me. It started when I noticed unapproved commits on my GitHub. After investigating, I traced the issue to a frontend project I was workin
