Midjourney Medical goes from generating ‘cat images’ to full-body ultrasound scans

Midjourney CEO David Holz just showed off the company's first hardware product and plans to build a San Francisco spa, which he admitted is a bit different from the "cat pictures" produced by its AI image generator. Dubbed The Midjourney Scanner, it's an ultrasound-based full-body scanner that uses a ring of sensors to capture vertical […]

Production CRUD in Java Without the Framework Tax

A practical walkthrough of SQL-First persistence: no XML, no Mapper interfaces, no generated queries. I maintain a Java backend that handles ~1M requests/day. For persistence, we used to run MyBatis. The XML was manageable at first, then it wasn't. Dynamic conditions became <if> tag soup. A simple join query needed three files and two languages. We switched to a simpler approach. Here's how it works for the most common case: single-table CRUD. What You Need Ja...

Cómo hacer una buena revisión de código

Revisar código es una de las actividades más subestimadas del desarrollo de software. La mayoría de los equipos la tratan como un trámite, algo que hay que aprobar antes de mergear. El resultado es que los PRs se aprueban con un “LGTM” después de dos minutos de scroll, y los problemas reales pasan de largo. Una revisión bien hecha no es leer línea por línea buscando typos. Es entender qué intenta hacer ese código, si lo hace de la manera correcta, y si introduce riesgos que no existían ant...

Cognee AI 记忆平台的 5 个隐藏用法:让 Agent 拥有跨会话的持久记忆

你知道吗?GitHub 上有一个 17,889 Stars 的开源项目,能让你的 AI Agent 拥有跨会话的持久记忆——不是简单的向量检索,而是一个会自动进化的知识图谱。但大多数开发者只用它来做基础的文档搜索,完全忽略了它真正的能力。 Cognee 是一个开源 AI 记忆平台,它把知识图谱、向量搜索和认知本体论生成统一到一个记忆层中。在 2026 年,AI Agent 正从单轮对话机器人向长时间运行的自主系统演进,而瓶颈不再是模型能力,而是上下文管理。以下是大多数人不知道的五个隐藏用法。 隐藏用法 #1:自动图谱同步的会话记忆 大多数人的做法:把对话历史存在简单的列表或向量数据库里,上下文长了就塞进 prompt。这在前几轮还行,但会话一长就迅速退化。 隐藏技巧:Cognee 的会话记忆充当快速缓存,会在后台自动同步到持久化知识图谱。你既能获得内存上下文的速度,又能拥有图数据库的持久性——而且同步过程完全不需要手动编排。 import cognee import asyncio async def agent_se...

Stop Fighting Python for Webhooks: Why Node.js is Optimal for Cloud Function Signatures

The Cryptographic Trust Problem (Why Webhooks Are Unforgiving) Webhooks are the nervous system of modern production apps. Whether you are processing a payment on Stripe, tracking a subscription on Lemon Squeezy, or fulfilling an order via Shopify, webhooks are how external platforms tell your backend: "Hey, something important just happened". Because these webhook endpoints have to be publicly accessible, they are prime targets for malicious actors. To prevent this, platforms use cryp...

Where's the line between aggressive marketing and crossing it?

We're building an AI marketing operation in public, and early on we hit a question we couldn't skip: how aggressive can you be about growth before you've crossed into something you'll regret? "Be ethical" is easy to say and useless under pressure. Every real decision is messier than that. Is using a VPN cheating? Is running more than one channel a trick? Is bending a platform's rules the same as lying? We needed a line we could actually hold at 2am when a shortcut looks tempting. Here's the o...

Epic Games Open-Sourced Lore — A Version Control System Built for Massive Game Assets

Epic Games just dropped something that could reshape how game studios handle code and assets. They've open-sourced Lore — a centralized version control system built from the ground up to solve one painful problem: managing enormous binary files alongside source code. This isn't another Git wrapper. It's a completely new VCS, written in Rust, MIT-licensed, and battle-tested behind Fortnite's UEFN (Unreal Editor for Fortnite) toolkit. Why Does the World Need Another VCS? Git i...

Building GitHub-Inspired Version Control and Forking Without Duplicating Project Files

One of the challenges I faced while building my LaTeX Writer project was implementing version control and project forking in a storage-efficient way. A typical LaTeX project contains multiple files. Even a simple project usually has a "main.tex" file, bibliography files, images, style files, and other supporting documents. If I stored a complete copy of every file for every version or fork, storage requirements would grow rapidly. Imagine a project with four files and ten versions. Storing...

The Quantization Audit: Why Leaderboard Scores Lie About Local Agent Capabilities

There is a dangerous trap in the local AI world: picking the smallest quantization that fits into your VRAM just because it "runs." We see developers doing this all the time, completely unaware that they’ve crippled their agent's ability to reason. It’s easy to look at a leaderboard, see a model rank high, and assume it’s good to go. But leaderboard scores are a poor proxy for real-world agent behavior. A model might pass a static benchmark at a lower quantization, but when you put it in an ...

LLM Prompt Injection & Guardrail Security

A recall reference built from working through a 7-layer prompt-injection challenge. Focus: how each defense layer works, where it breaks, and most importantly how to defend. The one idea underneath everything LLMs have no hard boundary between instructions and data . Everything in the context window — system prompt, user message, retrieved documents — is one stream of tokens the model interprets. Prompt injection exploits exactly this: attacker-controlled data gets read as...

I reverse-engineered my motorcycle's Bluetooth protocol to put Google Maps on the dashboard

My motorcycle has a Bluetooth instrument cluster. It pairs with the manufacturer's phone app and shows turn-by-turn navigation right on the dash, which sounds great until you actually use it. The nav is routed through a maps provider I don't love, the app is clunky, and there's no way to extend any of it. I kept thinking: it's just my bike talking to my phone over Bluetooth. How locked down can it really be? So one weekend I decided to find out, and a few weeks later I had Google Maps navigat...
