Ask HN: Switching from backend development to graphics programmingIMAGE

Ask HN: Switching from backend development to graphics programmingI love computers. I wrote my first program in Borland C++ when I was 11.By chance, I managed at my 15 to get a job where I did some HTML pages and later some PHP programming. Making websites wasn't as fun as making games in C++. Overall PHP didn't seem as fun as C++. I made all of my lab projects at the university in C++ with Qt, or wxWidgets or bare WinAPI. In fact, I improved the university the internal testing system on our Math/Physics faculty. I got a privilege to do labs in C++ & Qt even when they were supposed to be C#. Also, in the university I came across Linux and never came back.Nevertheless, I couldn't get a position as C++ programmer and stuck in web development for 15 years. I focused on backend and took care the systems reliability where I could apply my passion about systems programming. I took all of the possible challenges related to the performance and reliability. In fact, it was awesome making graphs with Graphviz or plots/heatmaps in Grafana to troubleshoot the sy

Best way to avoid bloat and AI – selfcontaining OSI wanted an OS that I could truly own. Most modern systems have become server-controlled clients, bloated with dependencies (Gtk4/Qt/Rust/Wayland) and centralized source control on GitHub. If you cannot audit the dependency tree and Big Corp controls the source, it is no longer real open source.I built OneManBSD to address this. It is an OpenBSD-based system built on a single 2012 ThinkPad L430.Project Video: https://www.youtube.com/watch?v=2wHaoQhXOYY Project Page: https://bialamusic.com/onemanBSD/

Show HN: macOS Apps on Linux: SwiftUI for Linux (and AppKit, NSFoundation, etc.)I made an open-source project that will take an existing macOS swift project and make it easily compile into a Linux (GTK/ or Qt). It's part of a new quality Swift-first OS I am making called QuillOS.I'm eager for help and for feedback.Also looking for people who have Swift code (there is very little open source swift code) who can give me example apps to compile against this to find any missing holes. The simpler/smaller the better but any size good.It's also easy to convert any working iOS app and adapt it to macOS with Claude, and then also cross-compile to Linux with this.https://github.com/Lore-Hex/QuillUI

Show HN: A nibble-oriented CPU in Verilog to build a scientific calculatorThe core question: how did HP's scientific calculators actually work at the gate level? That rabbit hole led to building one from scratch.The architectural decision everything else follows from: a decimal calculator should store numbers as BCD — one decimal digit per 4-bit nibble. A standard byte-oriented CPU (Z80, 6502) fights that layout constantly. So I designed a small custom CPU in Verilog where 4 bits is the natural data width and memory is nibble addressable.What the project covers:- Custom CPU: Harvard architecture, 12-bit ISA, 8-state execution FSM, hardware stack guard with a FAULT state for microcode debugging- CORDIC for trig functions, verified to 14 significant digits- Two-pass assembler in Python (~700 lines)- Verilator + Qt framework: same Verilog source runs in simulation, as a desktop GUI debugger, as WebAssembly, and on real hardware- Scripting language on top of the microcode for adding functions without touching hardware- Custom PCB (EasyEDA/JLCPCB), battery, charg

Show HN: Linux installer .exe without pendrives (secure-boot compatible)It is fairly simple, but useful for non-power users: a statically-linked Qt app that gracefully edits Windows Boot Manager to do a reboot-once into GRUB, which in turn launches ZorinOS live/installer from disk loopback. I needed to make a custom initramfs with dislocker in it, and to squeeze it a little (default Windows EFI partition is not so big).Currently my biggest issue is that systemd is unable to shut down gracefully when rootfs is mounted from such a deep loop stack. The other is that installing to full disk crashes right after it successfully damages the partition table. I think I could solve both by copying the ISO contents to ramdisk before systemd takes over (initramfs needs to stay slim as I mentioned before) - maybe opportunistically if there is enough RAM (3,5G is not so unreasonable to expect).I decided to make it paid for now (maybe not eligible for show? if so, sorry, I've been mostly a HN reader so far), but I am still considering if my project brought more good by b

Show HN: 1B EmbeddingsWe built a vector search engine based on Quantized Tensor Train (QTT) decomposition. Instead of approximate nearest neighbor (ANN) indices like HNSW or IVF, we factorize the entire dataset into a compressed tensor format and serve exact cosine similarity queries directly from the compressed representation. The headline: 1 billion vectors on a single H100, 38ms query, 100% recall, 66 GB serving.Recall improves with scale at fp16: 96% at 400M → 98% at 500M → 99% at 600M → 100% at 1B. This is the opposite of ANN indices, where recall degrades with scale. More data helps the decomposition converge.Every number below is measured, not projected. Full benchmark suite across 4 GPUs at 3 precision tiers. H100 80GB, 384-dim embeddings, rank=32.fp16 (Scale tier) — H100 80GB: 100M: 5.87ms p50, 6.6 GB serving, 100% recall, 46.5x compression 500M: 20.54ms p50, 33.0 GB serving, 98% recall, 46.5x compression 1B: 38.51ms p50, 66.0 GB serving, 100% recall, 46.5x compression fp32 (Production tier) — H100

Show HN: OneManBSD – A self-containing OpenBSD build with all source in the ISOThis major update. There is offline documentation included in the installer image now + some fixes. I built this because I am tired of OSs turning into server-controlled clients. We are losing the ability to understand, let alone rebuild, the tools we use every day.The Project: OneManBSD is a customized OpenBSD 7.8 installation image for i386 platforms.The "Sovereign" Features:Source in the Image: The installer includes sys.tgz, src.tgz, xenocara.tgz, and ports.tgz. You can go offline and rebuild the entire kernel and base system from the local drive.No Bloat: I’ve avoided Gtk3 and Qt. The desktop uses JWM, XFE, and Nedit.Hardware-Level Control: I’ve bypassed heavy audio daemons, using awk for notification beeps and raw mixerctl for hardware unmuting.Offline Docs: Full documentation is included in the image for true independence.Watch the 90-second demo (Boot speed & JWM setup): https://www.youtube.com/watch?v=2wHaoQhXOYYMy goal isn't to start a "distro" but to encourage others to buil

Show HN: QonQrete – Local-first multi-agent system for sandboxed code generationI’ve been working on an open-source project called QonQrete and would like feedback from HN.What it isQonQrete is a local-first, agent-based orchestration system for code generation. It coordinates multiple LLM “agents” to plan, write, and review code, while keeping execution inside a sandbox on your own infrastructure. Think of it as a construction yard for AI-assisted development that you run yourself.Why I built itMost multi-agent demos I saw had two issues:– Security: generated code often runs in the same environment that’s orchestrating it.– Observability/control: long agent chains become opaque, and it’s hard to insert human checkpoints cleanly.I wanted a setup where:– Agent-produced code runs in isolated containers.– The orchestration layer never directly executes that code on the host.– You can choose between fully automatic cycles and human-in-the-loop approval.ArchitectureCurrent pipeline:– InstruQtor: takes a high-level task and breaks it into an execution plan.– ConstruQtor

Show HN: AWS CodePipeline events via MQTT – with Tailscale supportTLDR; what the title says: AWS CodePipeline events via MQTT, optionally with Tailscale support, vended as a CDK construct.I've recently been working on a couple of side projects in AWS that are all CI/CD-ed via AWS CodePipelines and I ran into a problem: my PC is in my office on the 3rd floor but I hang out with my wife and dogs on the 1st floor between code sessions. When I push code out I have to wait for the deployment to flow through the pipeline so I'll head downstairs to burn that time while getting some quality time in with the family.However! Sometimes I'll push something that breaks the pipeline, defeating the whole purpose of pushing and leaving. This then led to me getting paranoid/fixated and logging in via the AWS app on mobile a bunch to check in on the pipeline statuses - a huge pain if you've ever done the following dance: log in via SSO through the app -> open authenticator for TOTP -> pick the correct account -> navigate back because it's not the correct account -> cl

Fundraising from... you - Need $5,000 from 500 people, each giving us $10.https://www.fundable.com/groupactions/groupaction.2007-12-19.5536225936We really need to finish this project and we need $5K from 500 people total, each giving us $10. We're a 2 man startup in Palo Alto. We're looking for angel investors for a while but can't really get connected or referred. It's been more than 8 months since we started working on it. We're close to a private beta, but we can no longer work full-time on it. We just need to get a day time job again to pay rent and food.With $5k we can go full-time again for 2~3 months and finish beta much, much faster.Since we're asking money from you, we have our executive summary, resumes, and a 5-min presentation movie available for download.- Presentation Moviehttp://bookvair.com/pitch-qt.html- Executive Summary and resumeshttp://bookvair.com/bookviar_files.zip- Project Pagehttp://bookvair.com We'd also like to invite contributors to be our first group of users, and give them special deals when we roll out book swapping features.I
