Show HN: X-Pilot – Code-Driven AI Video Generator for Online Courseshttps://www.x-pilot.ai/Hi HN,I'm Heshan, founder of X-Pilot. We're building an AI Video Generator for online courses and educational content. Unlike most text-to-video generator that render videos directly from models (which often produce random stock footage unrelated to the actual content), we take a code-first approach: generate editable code layers, let users verify/refine them, then render to video.The Problem We're SolvingMost AI video generators treat "education" and "marketing" the same—they optimize for "looks good" rather than "logically accurate." When you feed a technical tutorial or course script into a generic video AI, you get: - Random B-roll that doesn't match the concept being explained - Incorrect visualizations (e.g., showing a "for loop" diagram when explaining recursion) - No way to systematically fix errors without regenerating everythingFor educators, corporate trainers, and knowledge creators, accuracy matters more than aesthetics. A single incorrect diagram can break a learner's menJan 21, 2026 1:24 PM

Magnetic avalanches power solar flares, finds Solar Orbiterhttps://www.esa.int/Science_Exploration/Space_Science/Solar_Orbiter/Magnetic_avalanches_power_solar_flares_finds_Solar_OrbiterJust as avalanches on snowy mountains start with the movement of a small quantity of snow, the ESA-led Solar Orbiter spacecraft has discovered that a solar flare is triggered by initially weak disturbances that quickly become more violent. This rapidly evolving process creates a ‘sky’ of raining plasma blobs that continue to fall even after the flare subsides.Jan 21, 2026 8:00 AM

Show HN: Agentic coding – a practical guide to building with coding agentshttps://agenticoding.ai/Agentic coding is getting a lot of attention, but most explanations stay abstract or stop at demos.This is a short, hands-on course on building with coding agents: how to structure agent loops, when autonomy helps vs hurts, how tools and memory are actually used, and where things tend to break in real projects.The course focuses on:* Practical agent loop patterns (plan → act → reflect and variants)* Tool use, context management, and guardrails* Common failure modes (hallucinations, drift, runaway autonomy)* Tradeoffs between control, reliability, and speedIt’s aimed at engineers who want to go beyond toy examples and actually ship things with coding agents. Not a framework, not a product — just structured lessons based on real-world patterns.Feedback and critiques welcome, especially from people already building agents in production.Jan 20, 2026 9:13 PM

Show HN: I built a GPT that breaks logic into jokeshttps://humoropedia.com/I always loved comedy and humor in all their manifestations. I always loved comedy movies and standup routines. I also truly believed - and still believe - that laughter is an excellent medicine, not the best medicine though.That love for humor led me to the creation of Humoropedia.com. At its height of popularity, it was receiving about 200 thousand visitors a month, mostly from Google Search.Now that we have entered an age of AI - for better or worse, who knows - I decided that Humoropedia.com should become AI-enabled because these days you can be either AI-disabled or AI-enabled. So I chose to make Humoropedia.com AI-enabled, or at least as AI-enabled as a GPT Builder would allow me.That's how Humoropedia GPT was born. But how does it work and what does it do?Well, why don't we allow Humoropedia GPT to answer the following question: how do you work and what do you do?

Show HN: 4x faster Deep Learning training – we replaced the DataLoader with Rusthttps://news.ycombinator.com/item?id=46694336Hi HN, We built a drop-in replacement for torch.utils.data.DataLoader in Rust.The Problem: Python's multiprocessing isolates workers, meaning every batch incurs IPC and pickling overhead. Even on a T4, the CPU bottlenecks and the GPU sits idle.The Solution: We bypass Python's data plane entirely. Rust Backend: Uses native threads (no GIL, no heavy process forking). Zero-Copy: Memory-mapped custom format (.kt) creates views into tensors without deserialization.Benchmarks (ResNet-18 / ImageWoof, Tesla T4, batch=64): Loader Throughput Speedup (Time taken per epoch/Total number of images) PyTorch ImageFolder 116 img/s 1.0x MosaicML Streaming 179 img/s 1.5x NVIDIA DALI 246 img/s 2.1x Kuattree (Ours) 512 img/s 4.4xCompared to DALI, we are 2.08x faster. Compared to PyTorch, we are 4.4x faster. You have to pre-convert your dataset to .kt. It is similar to writing a TFRecord or WebDataset, but designed for random access, and 60x faster than MosaicML sharding.Not open source yet, but we're runniJan 20, 2026 5:00 PM

Show HN: Mastra 1.0, open-source JavaScript agent framework from the Gatsby devshttps://github.com/mastra-ai/mastraHi HN, we're Sam, Shane, and Abhi.Almost a year ago, we first shared Mastra here (https://news.ycombinator.com/item?id=43103073). It’s kind of fun looking back since we were only a few months into building at the time. The HN community gave a lot of enthusiasm and some helpful feedback.Today, we released Mastra 1.0 in stable, so we wanted to come back and talk about what’s changed.If you’re new to Mastra, it's an open-source TypeScript agent framework that also lets you create multi-agent workflows, run evals, inspect in a local studio, and emit observability.Since our last post, Mastra has grown to over 300k weekly npm downloads and 19.4k GitHub stars. It’s now Apache 2.0 licensed and runs in prod at companies like Replit, PayPal, and Sanity.Agent development is changing quickly, so we’ve added a lot since February:- Native model routing: You can access 600+ models from 40+ providers by specifying a model string (e.g., `openai/gpt-5.2-codex`) with TS autocomplete and fallbacks.- GuardJan 20, 2026 4:38 PM

Show HN: Klyve - A local-first Software Factory (Automated SDLC) for solo devshttps://news.ycombinator.com/item?id=46692838Hi HN, I’m Mario. I retired in Dec 2024 after 35 years in software services and Operations Research.I wanted to keep building, but I found the current set of chat LLMs frustrating for building complete applications. They are great at generating code (10% of the job) but not that useful when it comes to implementing specs for a full architecture, and then doing the testing and other project activities within the same context, and documentation (the 90% that makes the job a complete formal project).I realized I didn't need a "coding partner". I needed a software services factory.So, I built Klyve ( https://klyve.online ). It is a desktop orchestrator (Windows/Linux) designed to let Solo Senior Developers scale themselves by automating the SDLC, not just the typing.The Core Philosophy: Determinism over probabilistic vibeThe Orchestrator (Not a Wrapper): Klyve treats the LLM as a stochastic component within a deterministic State Machine. It does not chat. It executes the SDLC as a strict wJan 20, 2026 3:31 PM

Ask HN: Do you have any evidence that agentic coding works?https://news.ycombinator.com/item?id=46691243I've been trying to get agentic coding to work, but the dissonance between what I'm seeing online and what I'm able to achieve is doing my head in.Is there real evidence, beyond hype, that agentic coding produces net-positive results? If any of you have actually got it to work, could you share (in detail) how you did it?By "getting it to work" I mean: * creating more value than technical debt, and * producing code that’s structurally sound enough for someone responsible for the architecture to sign off on.Lately I’ve seen a push toward minimal or nonexistent code review, with the claim that we should move from “validating architecture” to “validating behavior.” In practice, this seems to mean: don’t look at the code; if tests and CI pass, ship it. I can’t see how this holds up long-term. My expectation is that you end up with "spaghetti" code that works on the happy path but accumulates subtle, hard-to-debug failures over time.When I tried using Codex on my existing codebases, with or Jan 20, 2026 12:45 PM
