Show HN: Forkrun – NUMA-aware shell parallelizer (50×–400× faster than parallel)https://github.com/jkool702/forkrunforkrun is the culmination of a 10-year-long journey focused on "how to make shell parallelization fast". What started as a standard "fork jobs in a loop" has turned into a lock-free, CAS-retry-loop-free, SIMD-accelerated, self-tuning, NUMA aware shell-based stream parallelization engine that is (mostly) a drop-in replacement for xargs -P and GNU parallel.On my 14-core/28-thread i9-7940x, forkrun achieves:* 200,000+ batch dispatches/sec (vs ~500 for GNU Parallel)* ~95–99% CPU utilization across all 28 logical cores, even when the workload is non-existant (bash no-ops / `:`) (vs ~6% for GNU Parallel). These benchmarks are intentionally worst-case (near-zero work per task) because they measure the capability of the parallelization framework itself, not how much work an external tool can do.* Typically 50×–400× faster on real high-frequency low-latency workloads (vs GNU Parallel)A few of the techniques that make this possible:* Born-local NUMA: stdin is splice()'d into a shared memfd, theMar 27, 2026 12:12 PM

Show HN: Veil – Dark mode PDFs without destroying images, runs in the browserhttps://veil.simoneamico.com/Hi HN! here's a tool I just deployed that renders PDFs in dark mode without destroying the images. Internal and external links stay intact, and I decided to implement export since I'm not a fan of platform lock-in: you can view your dark PDF in your preferred reader, on any device. It's a side project born from a personal need first and foremost. When I was reading in the factory the books that eventually helped me get out of it, I had the problem that many study materials and books contained images and charts that forced me, with the dark readers available at the time, to always keep the original file in multitasking since the images became, to put it mildly, strange. I hope it can help some of you who have this same need. I think it could be very useful for researchers, but only future adoption will tell.With that premise, I'd like to share the choices that made all of this possible. To do so, I'll walk through the three layers that veil creates from the original PDF:- Layer 1: CSS fMar 26, 2026 11:47 AM

XReplicator – eBPF-based server backups that track only changed disk sectorshttps://news.ycombinator.com/item?id=47527328I've been in cloud/platform engineering for a decade. One thing that always frustrated me: every backup tool either relies on fragile kernel modules for change block tracking, or does full-disk scans even when 1% of data changed. So we built XReplicator. It uses eBPF tracepoints to track dirty sectors at the block device layer — no kernel modules, no hypervisor APIs, no cloud-specific hooks. The agent runs inside the VM and works on any platform. Kernel devs called me mad for using eBPF for disk data replication. But the numbers speak for themselves:Full backup: ~17 minutes Incremental after 1.4% change: ~2 minutes Incremental after 0.4% change: ~56 seconds 71x less data scanned vs full backup 65–72% storage savings (LZ4 + block-level dedup)No kernel module compilation per kernel version, no reboots, sandboxed execution via the eBPF verifier. Restore at file, partition, or full disk level from any point in the chain. Honest caveat: the eBPF path only works on Linux kernel 5.10+. For leMar 26, 2026 6:46 AM

Show HN: CSS primitives for product videos, no render pipelinehttps://www.aliveui.dev/video-blocksMost product demo videos are made in screen recorders or tools like Remotion that render frames to MP4. I wanted something different: drop a CSS class on any HTML element and get cinematic motion that's ready for a product video, entirely in the browser. AliveUI Video Blocks is a set of CSS utility classes for common video UI primitives: animated metric cards, toast notifications, typewriter text, kinetic typography, lower thirds, scene backgrounds (aurora, starfield, bokeh), device frames, 3D effects, and particle FX. The interesting technical bit: there's no render pipeline. Animations run as native CSS keyframes. A small runtime (~2KB) handles declarative scene sequencing via data attributes, restarts animations on scene activation via an offsetHeight reflow trick, and drives CSS transition classes between scenes. The tradeoff vs Remotion: you can't do frame-perfect programmatic video or export a standalone MP4 without a headless browser. What you get instead is instant playback, zeMar 23, 2026 10:57 AM

Show HN: AgentDeals – Developer pricing discovery for AI agentshttps://github.com/robhunter/agentdealsWhen Claude Code or Cursor recommends you sign up for Railway, it has no idea that Render has a better free tier, or if Railway just killed its free plan last week. Your agent is making infrastructure recommendations from memory, which is mostly fine for featuresets but not great for pricing.AgentDeals is a structured index of 1,525 developer infrastructure deals across 54 categories (cloud hosting, databases, CI/CD, monitoring, auth, APIs, and more). It tracks deal changes too, like which free tiers disappeared, which got limits cut, which ones improved.Three ways to use it: 1. Browse: https://agentdeals.dev 2. REST API: /api/offers, /api/categories, /api/changes (no auth) 3. MCP server: connect from Claude, Cursor, VS Code Copilot, or any MCP clientThe MCP server has four intent-based tools - search_deals, plan_stack, compare_vendors, track_changes - so your agent can query deals as part of its normal workflow.

Show HN: Lukan – An open-source agentic workstation in a single Rust binaryhttps://lukan.aiHi HN, I've been building Lukan, an open-source (MIT) agentic workstation that runs entirely as a single Rust binary with zero runtime dependencies. I started this because I wanted a unified workstation optimized for my own productivity. My goal was to build an environment where I could securely remote into my machine from anywhere, seamlessly view and modify local files, and run AI agents or drop into a terminal side-by-side, all integrated with a rich set of built-in tools. Here is what makes it different: Multi-agent sessions: Run multiple agents in parallel, each with its own isolated context and history. You can switch between them using tabs, resume after disconnects, and even rewind to previous checkpoints. Embedded terminal: A full tmux-backed terminal lives inside the Web and Desktop UI. Sessions survive page reloads and network drops. You can run any CLI tool alongside your agent (including Claude Code, Codex CLI, Lukan Cli, etc.).

Launch HN: Kita (YC W26) – Automate credit review in emerging marketshttps://news.ycombinator.com/item?id=47417335Hey HN! We’re Carmel and Rhea, the founders of Kita (https://www.usekita.com/). We automate credit review for lenders in emerging markets using VLMs.In many emerging markets, like the Philippines and Mexico, credit infrastructure is weak. Open finance is still nascent, and credit bureaus are unreliable. So to apply for a loan, lenders rely on borrowers submitting documentation to understand their ability to repay. A borrower can submit financial documents, such as bank statements and payslips, in any format, from pdfs, images of physical documents and screenshots. On top of that, financial documents in these markets are highly unstandardized, with no consistent templates lenders can rely on.Existing OCR and document AI tools break on these highly variant, messy real-world documents. Generic tools are not built for lending workflows like verification, fraud detection, and risk extraction. As a result, credit teams fall back on manual review, making underwriting slower, more expensive, aMar 17, 2026 7:46 PM

Show HN: CredibilityProfile – bringing reference checks earlier into hiringhttps://www.credibilityprofile.com/Hi HN,I’ve been a startup operator and advisor for 10+ years, and one recurring frustration has been hiring, which got even worse with the introduction of some new AI tools: CVs are too polished, too many applications to screen, interview capacity is limited, real signal (how someone actually works) comes late via references — if at all.So we built a small tool: https://credibilityprofile.comIt lets candidates collect structured feedback from past managers/peers (with consent to be contacted), and share it as a reusable link in their CV.We ran an initial pilot in our hiring processes, and seen some promising results: Candidates were willing to complete and then re-use it in their CVs for their other applications.Right now, we’re testing it with other entrepreneurs/hiring managers/recruiters — with a very simple setup, at no cost (just adding a note to job posts).Open questions we’re still thinking about:- Is this meaningfully better than LinkedIn recommendations / references later in pMar 17, 2026 5:06 PM

I also realized that my opinion on what's worth buying is more than worthless, what matters is the opinion of the market.But I didn't want to settle for index funds that hold a lot of under-performing stocks so I've built this tool that allows trading 12000 instruments (stocks, ETFs, metals, real estate, crypto) via statistically proven strategies.Project is open source, tool is self-hosted, at the very minimum it requires an Alpaca brokerage account, they also provide the necessary market data, alternatively you can use Tiingo or EODHD.I'm currently running 2 paper trading accounts, fine-tuning parameters like slippage, planning to start ADX on real money soon.I'm not trying to beat hedge funds and other big players here, instead I'm looking to join them by waiting for a trend to be established (daily time frame, wide stops, long duration trades) and naturally diversifying over all Mar 16, 2026 8:36 PM

The Quiet Normalization of Artificial Intelligencehttps://news.ycombinator.com/item?id=47401303Over the past few years, it has become almost routine to hear warnings about artificial intelligence. Headlines often focus on the risks. Job displacement, algorithmic manipulation, surveillance, loss of control over autonomous systems. In public debates, AI frequently appears as a looming threat, something powerful and unpredictable that could reshape society in dangerous ways.Yet at the very same time that these fears dominate the conversation, something quieter has been unfolding. Millions of people have already woven artificial intelligence into their daily routines. They rely on algorithms to help write emails, ask digital assistants for research guidance, receive recommendations about what to watch or read, and use AI-powered tools to accelerate their work. The criticism grows louder, but the habit grows stronger.The data reveals a striking contradiction.

Ask HN: AI Agents vs. Gateways vs. Harnesseshttps://news.ycombinator.com/item?id=47397737Hi,I'd like to get everyone's take on the different components in the AI Agents ecoysystem. I find the current terminology quite confusing as it's not always obvious what I'll be actually getting when I examine the available options.A lot of things get called Agents, but that term seems hard to define as it often refers to overlapping functionality. To me, agents seem to be currently composed of the following components:## Harnesses- Adds UI and system instructions around an LLM and may also augment it with tools such as memory, tool calls, etc...- Examples are Claude Code, Code, Gemini CLI, pi.dev, ...## Gateways- These connect agents to your communication tool of choice, e.g. Whatsapp, Telegram, Slack, Discord, ...- Examples are OpenClaw and Nanoclaw## Sandboxes- Isolated environments where Agents can run with limited or auditable capabilities- Examples can be from physical ones like separate Mac Minis to docker-agent, agent-sandbox, localsandbox, ...This then takes us to *Agents*:##Mar 16, 2026 11:43 AM

Show HN: Dumped Wix, my AEC consultancy's storefront is now an AI Edgehttps://axoworks.com/I run a building design consultancy for homeowners and architects, not a SaaS firm. Honestly, I'm not going to claim we were trying to build some fantastic ‘anti-fragile alternative’ for the future… I just got tired of paying Wix $40 a month for a brochure no one read. The portfolio was static, the inquiries were generic, and every time a potential client asked about setback variances, I'd lose hours explaining the same thing. So last December, I told my wife I was killing the website. She thought I’d lost it. Maybe I had.The stack? It’s messy. We started on Netlify because it was cheap.
