Every week, over 1,300 US companies file a funding round with the SEC — and most of them never appear in the tech press. If your job involves selling to funded startups, tracking competitors' war chests, or spotting investment trends, you're probably relying on funding newsletters and databases that are days late and hundreds of dollars per seat. There's a better way: go to the primary source. In this tutorial you'll build a real-time startup funding feed from SEC Form D filings — the regulatory document every US company must file when it raises private capital. You'll get exact amounts, industries, locations and investor counts, as clean JSON, for a fraction of a cent per round. Why Form D beats funding news When a startup raises money under Regulation D (the exemption used by virtually all US venture rounds), it must file Form D with the SEC within 15 days of the first sale. That filing includes: The exact amount sold so far — not a journalist's "sources say" estimate The total offering size (or whether it's open-ended) Industry group, city and state Number of investors who participated Date of first sale and year of incorporation Compare that to funding news: TechCrunch covers a tiny, PR-driven slice. Databases like Crunchbase aggregate press and manual research — comprehensive over time, but late and expensive. Form D is the ground truth both of them chase. The catch? EDGAR (the SEC's database) is built for lawyers, not for automation. The filings are XML documents scattered across an archive, discoverable only through a quirky full-text search API with hidden rate limits. That's the part we'll automate. The 5-minute setup We'll use the Startup Funding Feed Actor — it handles EDGAR's discovery API, XML parsing, rate limits and pagination, and returns one JSON record per filing. It's pay-per-event: $0.002 per filing returned (a full weekly sweep of all US rounds costs ~$2.60; a filtered slice costs cents). Failed fetches are never charged. Create a free Apify acc

There is a fascinating, quiet tension happening in the software engineering community right now. If you listen closely to late-night developer chats, team syncs, or tech forums, you will notice that our industry has rapidly split into two distinct schools of thought regarding the rise of AI coding tools like Cursor, Claude Code, and Copilot. On one side, you have the Traditional Developers. They argue that software engineering is a disciplined art form that cannot be replaced by text prompts. To them, unchecked AI coding is a recipe for buggy, unreadable spaghetti code, creating a technical debt nightmare for the future. On the other side, you have the Vibe Coders. This is a fast-moving generation of builders, both technical and non-technical, who believe in shipping fast, prompting quickly, and adjusting on the fly. They do not see a need to obsess over syntax when the AI can translate their intent into a working application in minutes. The reality is that both sides are entirely right. If we stop arguing over who is ruling the current meta and actually look at the core truths each camp holds, we can see exactly where the future of software development is heading. 1. The Traditional Developer is Right: Guardrails Matter The traditional development camp is fundamentally right about structure. Building a beautifully designed UI that works on a surface level is vastly different from building an enterprise-ready, scalable architecture. When you prompt an AI to build a feature, its primary objective is to satisfy the literal words in your core prompt. This is the "as long as it works" mentality. Unless you are practicing strict, spec-driven development and explicitly dictating your architectural doctrines, security protocols, and API patterns, the AI will make assumptions for you. Historically, those assumptions are optimized for speed and not long-term stability. Without deep technical oversight to catch anti-patterns, edge cases, and hidden security flaws, fast-shippe

Hardwood, the project Gunnar Morling kick-started handling of Parquet files in Java, reached version 1. Its multi-threaded approach and zero mandatory external dependencies promise a simpler, more efficient alternative to the Apache Parquet Java implementation. For now, the library supports just reading; writing support is expected in the upcoming versions. By Olimpiu Pop

This is from a 2024 company presentation : Officers can also tap into data showing a car’s decals, bumper stickers, back and top racks—along with temporary and unique state tags. Flock calls it a “Vehicle Fingerprint” and it’s touted as a way for law enforcement officials to get more information “even when you don’t have full plate information,” the company’s presentation shows. The company gives police officers the ability to search that data as well, to “build stronger cases with less information upfront.” That includes being able to locate multiple vehicles law enforcement officials believe are moving together and what Flock calls a “multi geo search.”...

For the past two years, the AI world has been obsessed with finding the perfect prompt or building better UI wrappers around LLMs. But while everyone was distracted by the models themselves, a silent revolution happened at the architecture layer. It is called Agentic AI , and it is being entirely reshaped by a new standard: Model Context Protocol (MCP) . If you are building AI agents in 2026 and you aren't using MCP, you are already falling behind. Here is why this changes everything. The Problem: The Custom Tooling Nightmare Up until recently, building an autonomous AI agent was incredibly fragmented. If you wanted your agent to read a GitHub repository, query a Postgres database, and send a Slack message, you had to write custom tool-calling logic for every single integration. Every time Anthropic, OpenAI, or Google released a new model, you had to adapt your tool schemas. It was a brittle, non-standardized nightmare. Enter MCP (Model Context Protocol) MCP solves this by introducing a universal, open standard for connecting AI models to data sources and tools. Think of it like a USB-C cable for AI. Instead of writing custom API wrappers for your agent, you simply build or download an MCP Server . An MCP Server is a standalone program that exposes specific capabilities (like "Search the web" or "Read a local file"). Any agent, regardless of the underlying LLM, can connect to that server and instantly understand how to use its tools. Why This Changes Agentic AI Forever Plug-and-Play Ecosystem: We are seeing the birth of an "App Store" for AI tools. Developers are open-sourcing MCP servers for absolutely everything: Jira, GitHub, AWS, local file systems, and more. True Autonomy: Because the protocol standardizes how context is passed, agents can autonomously discover what tools a server has, read the instructions, and chain them together without human intervention. Security and Isolation: You can run an MCP server in a secure, sandboxed environment (like a Docker con

There is a ghost haunting the tech industry right now, and nobody wants to talk about it: The Junior Developer role is disappearing. With tools like GitHub Copilot, ChatGPT, and advanced coding agents becoming standard issue in every IDE, senior developers are suddenly 10x more productive. They no longer need a junior developer to write boilerplate code, write unit tests, or scaffold out basic UI components. The AI does it instantly. So, if you are a junior developer, or aspiring to break into tech, how do you survive? 1. Stop Memorizing Syntax, Start Thinking Architecturally AI is incredible at writing syntax, but it is terrible at system design. If your only skill is writing a for loop in React, you are competing with an AI that works for $20/month. Instead, focus on understanding how systems fit together. Learn about cloud architecture, database indexing, and distributed systems. The AI can write the function, but you have to know where that function lives and how it scales. 2. Become a "Domain Expert" Developer AI doesn't understand the nuanced business logic of the healthcare industry, or the strict compliance regulations of fintech. If you combine coding skills with deep industry knowledge, you become irreplaceable. 3. Embrace the Tools (Be the Orchestrator) Don't fight the AI. Master it. The developers who thrive in the next decade will be the ones who treat AI agents like a team of junior developers reporting to them. Learn how to craft the perfect prompts, how to use Retrieval-Augmented Generation (RAG), and how to orchestrate multiple LLMs to build complex applications. The barrier to entry for writing code has dropped to zero. But the barrier to entry for building valuable software remains exactly the same. Are you terrified of AI replacing you, or are you using it to level up?

The product drop had been planned for months. The direct-to-consumer subscription business had run three separate load tests, provisioned extra capacity for the launch window, and staffed a warroom across two time zones. The drop itself went cleanly. Two hours in, an unrelated video from a creator with a large following mentioned the product without warning, and the sign-up flow collapsed under a rush of new members for twenty-eight minutes. Customers were told the site was busy and to try again later. Some did. Most did not. The refund exposure was manageable. The customer acquisition exposure was not. What went wrong is not the interesting question. The system was under-provisioned for a specific traffic shape it had not seen before, and the team fixed it. The interesting question is what happened seven weeks later. A weather event redirected a wave of app traffic in an entirely different sector, at midnight on a Tuesday, without any warning. That system held, because a small group of engineers had spent those seven weeks quietly rebuilding assumptions about when peak load happens and what it looks like. The lesson from the product drop was not "provision more capacity for product drops." The lesson was that the mental model of peak load as a scheduled event had stopped being useful. This is another post in our series on the engineering layer underneath enterprise strategy. The previous post ( Sovereignty Versus Efficiency ) argued that sovereignty has become an architectural property that procurement cannot solve on its own. This post makes an analogous argument about load. Across banking, media, retail, travel, restaurant chains, and sport, the architectures built to survive named events are increasingly the wrong architectures for the traffic these businesses now routinely encounter. The discipline required has moved closer to what telecommunications engineers have always done, while the cost models have not caught up. What peak load used to mean For most of th

​ For open-weight LLMs, how practical is it to study defenses against post-release fine-tuning that weakens refusal or safety behavior? I've been seeing “uncensored” or “heretic” variants of new models appear very quickly after release, which raises a question I’m curious about: is fine-tuning resistance a meaningful safety goal for open-weight releases, or is it too narrow because determined users can always modify weights, switch models, or use other workarounds? And to a larger extent, is current safety training even worth the cost and effort if it takes 30 minutes and an automated script to break the model? I’m not asking about a specific method, just the threat model. What would count as a useful practical win here? For example, would increasing attacker cost or making safety removal less reliable be valuable, even if perfect prevention is impossible? Curious how people think about this from a model release, governance, and AI safety perspective. submitted by /u/Aaron_Rock [link] [留言]

As the parent of two little girls, I often think about how their childhood is different from mine. The seven-year-old is learning about AI at school. The five-year-old is given internet-based homework every week. And they are both absolutely repulsed by the idea of smoking. That was not the prevailing sentiment when I was young.…
