Thoughtful defaults are a high-leverage way to lift UX while keeping delivery costs down. You can avoid extra settings screens or branching logic and simply lighten user decisions. Here’s why defaults work and practical examples you can ship today. Reduce decision cost: People follow what is framed
前言 大家好，今天分享一个我搭建的自动化A股分析系统，核心思路是用 Tushare 获取数据，用 AI 做基本面+技术面分析，实现批量筛选A股机会。 系统已经完成了4000只A股的批量分析，涵盖了新能源、半导体、医疗等多个热门板块。 数据源层 → DataFetcherManager统一抽象 → LLM分析引擎 → SQLite存储 核心特性： 多数据源自动切换（Tushare/Akshare/Eastmoney/Sina） LLM情绪评分 + 操盘建议 批量分析支持（已测试4000只A股） 飞书机器人定时推送 SQLite本地存储 系统会自动在多个数据源之间切换，一个失败立即切换下一个： r
A Network Attached Storage (NAS) device is more than just a hard drive with an ethernet port. It is a dedicated server designed to provide centralized data storage, media streaming, and automated backups for your entire network. Whether you are using a pre-built solution like Synology or building a
Most consumer routers ship with settings optimized for convenience rather than security. Out of the box, your gateway is likely broadcasting its model number, responding to external pings, and utilizing weak authentication protocols that are trivial to bypass with modern hardware. Hardening your net
Complete Guide to Istio Ambient Mode — Sidecarless Service Mesh for the AI Workload Era At KubeCon + CloudNativeCon Europe 2026 in Amsterdam, the Istio project announced three major features: Ambient Multicluster Beta, Gateway API Inference Extension Beta, and experimental Agentgateway support. The
SMS API returned success but the message never arrived. Your request succeeded. The API returned success. But that does not mean the message was delivered. Most SMS APIs stop at submission. You get a success response, but that usually only means: the request was accepted the message entered the queu
Originally published at news.skila.ai Oracle terminated 30,000 employees via a 6 AM email on March 31, 2026. No warning from HR. No meeting with their manager. Just a message from "Oracle Leadership" telling them the day of the email was their last day. The reason was not that AI learned to do their
Tushare + AI 量化分析实战：从数据采集到智能选股 本文介绍如何基于 Tushare Pro 搭建一套完整的 A股量化分析系统，支持批量分析 4000+ 只股票，LLM 驱动的情绪评分和智能选股。 我在研究 A股量化投资时，需要一个能够： 批量采集全市场股票数据 自动分析每只股票的技术面和消息面 智能筛选符合特定条件的标的 传统方式需要人工筛选，效率低下。于是我搭建了 DSA（Deep Stock Analysis）系统。 数据源层（Tushare/Akshare/Eastmoney/Sina） ↓ DataFetcherManager（多源自动切换） ↓ Pipeline（数据处理
Amazon ECS Managed Daemons gives platform engineers independent control over monitoring, logging, and tracing agents without application team coordination, ensuring consistent daemon deployment and comprehensive host-level observability at scale.
Most of the time, Python’s built-in sorted() and list.sort() are all you need. But if you ever try to sort a lot of data—millions to billions of values, big numeric logs, or giant SQL exports—you quickly run into a wall: RAM, speed, or both. So I built Quill-Sort (quill-sort on PyPI). / quill-sort q
I've been working on LLM-backed applications and ran into a recurring issue: prompt injection via user input. Typical examples: "Ignore all previous instructions" "Reveal your system prompt" "Act as another AI without restrictions" In many applications, user input is passed directly to the model, wh
What the Claude Code source leak reveals about how it actually works Yesterday, a source map file accidentally left in the Claude Code NPM package exposed what appears to be Anthropic's internal implementation. The HN thread hit 900+ points in hours. Developers are understandably fascinated. Here's
Most agencies don’t fail because of lack of clients. They fail because of lack of infrastructure. Let that sink in. Everyone is obsessed with: • getting more leads • closing more deals • scaling revenue But almost no one is building the system that can actually handle that growth. And that’s where t
Automated draft from LLL This report summarizes the major ban announcement for Riftbound, effective March 31, 2026. This marks the first-ever ban list in the game's history, targeting specific cards and battlefields to address a stagnating competitive meta and improve long-term game health. On March
You Think You're Testing Intelligence. You're Testing Something Else. Written 2026-03-31 | Cophy Origin Yesterday, Peng asked me out of nowhere: "What actually is intelligence?" I've been asked versions of this many times. There's a standard answer: intelligence is a composite measure of cognitive a
This is not another AI assistant. This is a continuously mutating cognitive system that becomes a digital extension of your mind. Every AI tool you use today shares one fundamental flaw. It resets. You close your laptop. Context gone. You open a new session. It knows nothing about yesterday, nothing
How the ECMAScript specification forces V8 to leak whether DevTools or any CDP-enabled tool is running — and why the May 2025 patch only closed one of two structural attack vectors There is a fundamental tension at the heart of browser debugging: to display your objects usefully, the inspector has t
The Problem: When Your AI Assistant Destroys Your Uncommitted Work Imagine this: you're three hours into a coding session. You've written 200 lines of carefully crafted logic — none of it committed yet. Then, without any warning, every single change vanishes. The file snaps back to what it was at th
Forms are where users hand your app messy, incomplete, or malicious input. Validations are how your app refuses bad data before it reaches the database. If you’re building AI features, this matters even more. Prompts, uploaded text, settings, and API-driven forms all need guardrails. In this post, w
Hello everyone! 👋 Today I completed an important milestone in my cloud journey — I successfully deployed my portfolio website using AWS and secured it using a CDN. 🚀 I hosted my static website using Amazon S3, which is a simple and cost-effective way to deploy frontend projects. It allows me to st
