Show HN: CleanAF – One-click Desktop cleaner for Windows Hi HN, I built CleanAF because my Windows Desktop kept turning into a dumping ground for downloads and screenshots. CleanAF is a tiny one-click tool that: keeps system icons intact moves everything else into a timestamped “Current Desktop” folder auto-sorts files by type requires no install, no internet, no background service It’s intentionally simple and does one thing only. Source + download: https://bit.ly/46adZuW I’m considering adding undo/restore, scheduling, and exclusion rules if people find it useful. Feedback welcome. https://bit.ly/46adZuW January 23, 2026 at 03:02AM

Show HN: High speed graphics rendering research with tinygrad/tinyJIT https://bit.ly/49NhyZb

Show HN: High speed graphics rendering research with tinygrad/tinyJIT I saw a tweet that tinygrad is so good that you could make a graphics library that wraps tg. So I’ve been hacking on a gtinygrad, and honestly it convinced me it could be used for legit research. The JIT + tensor model ends up being a really nice way to express light transport all in simple python, so I reimplemented some new research papers from SIGGRAPH like REstir PG and SZ and it just works. instead of complicated cpp its just a 200 LOC of python. https://bit.ly/4jSe38d January 22, 2026 at 04:26AM

Show HN: Sweep, Open-weights 1.5B model for next-edit autocomplete https://bit.ly/4qstJla

Show HN: Sweep, Open-weights 1.5B model for next-edit autocomplete Hey HN, we trained and open-sourced a 1.5B model that predicts your next edits, similar to Cursor. You can download the weights here ( https://bit.ly/49JsQO0 ) or try it in our JetBrains plugin ( https://bit.ly/49ElRpq... ). Next-edit autocomplete differs from standard autocomplete by using your recent edits as context when predicting completions. The model is small enough to run locally while outperforming models 4x its size on both speed and accuracy. We tested against Mercury (Inception), Zeta (Zed), and Instinct (Continue) across five benchmarks: next-edit above/below cursor, tab-to-jump for distant changes, standard FIM, and noisiness. We found exact-match accuracy correlates best with real usability because code is fairly precise and the solution space is small. Prompt format turned out to matter more than we expected. We ran a genetic algorithm over 30+ diff formats and found simple `original`/`updated` blocks beat unified diffs. The verbose format is just easier for smaller models to understand. Training was SFT on ~100k examples from permissively-licensed repos (4hrs on 8xH100), then RL for 2000 steps with tree-sitter parse checking and size regularization. The RL step fixes edge cases SFT can’t like, generating code that doesn’t parse or overly verbose outputs. We're open-sourcing the weights so the community can build fast, privacy-preserving autocomplete for any editor. If you're building for VSCode, Neovim, or something else, we'd love to see what you make with it! https://bit.ly/49SL9QV January 22, 2026 at 12:22AM

Show HN: E80: an 8-bit CPU in structural VHDL https://bit.ly/4pMdPAU

Show HN: E80: an 8-bit CPU in structural VHDL I built a new 8-bit CPU in VHDL from scratch (starting from the ISA). I felt that most educational soft-cores hide too much behind abstraction, eg. if I can do a+b with a single assignment that calls an optimized arithmetic library, then why did I learn the ripple carry adder in the first place ? And why did I learn flip flops if I can do all my control logic with a simple PROCESS statement like I would with a programming language ? Of course abstraction is the main selling point of HDLs, but would it work if I tried to keep strictly structural and rely on ieee.std_logic_1164 only ? Well, it did and it works nicely. No arithmetic libraries, no PROCESS except for the DFF component (obviously). Of course it's a bit of a "resource hog" compared to optimized cores, (eg. the RAM is build out of flip flops instead of a block ram that takes advantage of FPGA intermal memory) but you can actually trace every signal through the datapath as it happens. I also build an assembler in C99 without external libraries (please be forgiving, my code is very primitive I think). I bundled Sci1 (Scintilla), GHDL and GTKWave into a single installer so you can write assembly and see the waveforms immediately without having to spend hours configuring simulators. Currently Windows only, but at some point I'll have to do it on Linux too. I tested it on the Tang Primer 25K and Cyclone IV, and I included my Gowin, Quartus and Vivado projects files. That should make easy to run on your FPGA. Everything is under the GPL3. (Edit: I did not use AI. Not was it a waste of time for the VHDL because my design is too novel -- but even for beta testing it would waste my time because those LLMs are too well trained for x86/ARM and my flag logic draws from 6502/6800 and even my ripple carry adder doesn't flip the carry bit in subtraction. Point is -- AI couldn't help. It only kept complaining that my assembler's C code wasn't up to 2026 standards) https://bit.ly/3ZrvXoV January 17, 2026 at 10:39PM

Show HN: I quit coding years ago. AI brought me back https://bit.ly/49GCfWC

Show HN: I quit coding years ago. AI brought me back Quick background: I used to code. Studied it in school, wrote some projects, but eventually convinced myself I wasn't cut out for it. Too slow, too many bugs, imposter syndrome — the usual story. So I pivoted, ended up as an investment associate at an early-stage angel fund, and haven't written real code in years. Fast forward to now. I'm a Buffett nerd — big believer in compound interest as a mental model for life. I run compound interest calculations constantly. Not because I need to, but because watching numbers grow over 30-40 years keeps me patient when markets get wild. It's basically meditation for long-term investors. The problem? Every compound interest calculator online is terrible. Ugly interfaces, ads covering half the screen, can't customize compounding frequency properly, no year-by-year breakdowns. I've tried so many. They all suck. When vibe coding started blowing up, something clicked. Maybe I could actually build the calculators I wanted? I don't have to be a "real developer" anymore — I just need to describe what I want clearly. So I tried it. Two weeks and ~$100（Opus 4.5 thinking model） in API costs later: I somehow have 60+ calculators. Started with compound interest, naturally. Then thought "well, while I'm here..." and added mortgage, loan amortization, savings goals, retirement projections. Then it spiraled — BMI calculator, timezone converter, regex tester. Oops. The AI (I'm using Claude via Windsurf) handled the grunt work beautifully. I'd describe exactly what I wanted — "compound interest calculator with monthly/quarterly/yearly options, year-by-year breakdown table, recurring contribution support" — and it delivered. With validation, nice components, even tests. What I realized: my years away from coding weren't wasted. I still understood architecture, I still knew what good UX looked like, I still had domain expertise (financial math). I just couldn't type it all out efficiently. AI filled that gap perfectly. Vibe coding didn't make me a 10x engineer. But it gave me permission to build again. Ideas I've had for years suddenly feel achievable. That's honestly the bigger win for me. Stack: Next.js, React, TailwindCSS, shadcn/ui, four languages (EN/DE/FR/JA). The AI picked most of this when I said "modern and clean." Site's live at https://bit.ly/3NpNjA2 . The compound interest calculator is still my favorite page — finally exactly what I wanted. Curious if others have similar stories. Anyone else come back to building after stepping away? https://bit.ly/3NpNjA2 January 19, 2026 at 01:50AM

Show HN: Speed Miners – A tiny RTS resource mini-game https://bit.ly/4r3girW

Show HN: Speed Miners – A tiny RTS resource mini-game I've always loved RTS games and wanted to make a game similar for a long time. I thought I'd just try and build a mini / puzzle game around the resource gathering aspects of an RTS. Objective: You have a base at the center and you need to mine and "refine" all of the resources on the map in as short a time as possible. By default, the game will play automatically, but not optimally (moving and buying upgrades). You can disable that with the buttons. You can select drones and right click to move them to specific resources patches and buy upgrades as you earn upgrade points. I've implemented three different levels and some basic sounds. I used Phaser at the game library (first time using it). It won't work well on a mobile. https://bit.ly/4sLA7p7 January 17, 2026 at 10:40PM

Show HN: Building the ClassPass for coworking spaces, would love your thoughts https://bit.ly/4r1tk9p

Show HN: Building the ClassPass for coworking spaces, would love your thoughts Growing up in a family business focused on coworking and shared spaces, I saw that many people were looking for a coworking space to use for a day. They weren't ready to jump into a long-term agreement. So I created LANS to simplify coworking. Our platform allows users to buy a day pass to a coworking space in seconds. The process is simple: book your pass, arrive at the space, give your name at the front desk, and you're in. Where we are Live in San Francisco with several coworking partners. Recently started expanding beyond the Bay. 10K paid users in San Francisco. Day passes priced between $18 and $25. What we’re seeing Users often use this service. They rotate locations during the week to fit their needs and schedules. For spaces, it’s incremental usage and new foot traffic during the workday. Outside dense city centers, onboarding new spaces tends to be faster. Many suburban areas host nice boutique coworking spaces. But, they often miss a strong online presence. Day passes quickly appeal to both operators and users. What we’re working on Expanding to more cities. Adding supply while keeping quality consistent. Learning which product decisions actually improve repeat usage. Would love feedback from HN: Does this resonate with how you work today? Have you used coworking day passes before? Would you dump your coworking membership for this? https://bit.ly/4pIpSzm January 17, 2026 at 05:54AM
