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

NASA-ISRO Satellite Captures Pacific Northwest Through Cloudshttps://www.nasa.gov/missions/nisar/nasa-isro-satellite-captures-pacific-northwest-through-clouds/Seattle and Portland, Oregon, are among the cloudiest cities in the United States. But that infamous cloud cover is no match for the U.S.-Indian Earth satellite NISAR (NASA-ISRO Synthetic Aperture Radar), which is designed to peer straight through clouds. Doing so allows scientists to study the Pacific Northwest’s natural landmarks and bustling port cities like […]Mar 25, 2026 3:51 PM

Show HN: Visualizing Apple Health workout data (stats, trends, insights)https://apps.apple.com/us/app/streakout-workout-stats/id6758457318I've just launched this little iOS app as an alternative to Apple Fitness, which is cluttered and chaotic when it comes to visualizing basic workout stats and metrics.The idea is to focus on a clean, minimalistic design and only show high-level metrics that are actually useful, e.g. how often did I work out this week/month/year, cardio vs strength vs mobility, surf session count in February, etc.It's free and offline. Also, no signup, no ads, no data sharing, no social feeds, and no notifications.Just open it and get a quick glance at the state of your workout game within 2s.It's built in native Swift with liquid glass.Feedback is quite good so far, but it seems hard to get initial traction in the App Store, especially with all the AI slob these days. Would deeply appreciate some early downloads and honest reviews.Mar 24, 2026 3:56 PM

We Replaced Every Tool Claude Code Ships Withhttps://news.ycombinator.com/item?id=47468649Claude Code ships with Bash, Read, Write, Edit, Glob, Grep, WebFetch, Task, Plan. For a single agent on a single task, they're fine. Once you're running a multi-agent system, the defaults break fast.The problems we hit:1) No cross-repo exploration. Want an agent to read another project's code? You need to manually configure permissions. There's no "go explore this OSS repo and answer my question."2) Summarized web fetching. WebFetch is actually a subagent that summarizes a single page into a haiku-length response. Can't trace links or browse related pages. Fetches fresh every time — no caching.3) Text-level editing. Edit has fuzzy matching, which helps — but it's still raw text. When tree-sitter can give you an AST with named symbols, why make the model reproduce strings to target a function?4) Ephemeral tasks and plans. Tasks don't persist outside the session. Plans vanish when context resets. Neither supports multi-round review or structured editing.5) Flat delegation. The Agent toolMar 21, 2026 4:44 PM
