Ask HN: What Is Stripe Today?https://news.ycombinator.com/item?id=49150707I think Stripe’s internal strategy is a consolidation of products within its sector. Similar across other industries, such as cybersecurity, where I think Cloudflare is attempting to do the same. The broader idea is clearly enterprise consolidation. I think now is the correct period in the technology cycle for such consolidation.The influx of many enterprise companies was due to the advent from on premise computing/storage to the cloud, lowering the barrier to creating new companies. Hence, it was somewhat possible to create “Niche” enterprise businesses, such as a Dropbox or an Intercom. These businesses were able to create sustainable recurring profits because of a business model boom and customer captivity in terms of enterprise switching costs. Hence, none of these businesses are disappearing and should remain stable companies for a long time. There is a broader move to add company-adjacent products to further entrench customers and somewhat diversify from a core business.As costs

Show HN: Project ESPAÑOL: Find level-appropriate Spanish-language poemshttps://dmerullo.github.io/project-espanol/I made this application while taking Spanish lessons to find texts that used verb forms I was learning (present, past, future, subjunctive, etc.). First, I scraped ~10,000 Spanish-language poems from the web that are in the public domain. Then, I built a conjugation dictionary for the 550+ most common verbs, using rules to generate regular verbs, and scraping irregular verbs from the web. From this alone, you can identify which poems contain the most type of verbs you're trying to target. To take it further, I used a k-means clustering algorithm in Python to classify the poems into four difficulty levels based on verb form frequencies (poems with lots of verbs in subjunctive future perfect are more difficult than only present tense, for example).I first completed the project in December 2024, almost entirely by hand, using LLMs primarily to make an interactive Plotly Dash application. (I have a lot of experience with data visualization, especially ggplot2; that was my first time using

Show HN: Draco – A single-binary, self-hostable Firecrawl alternative in Rusthttps://github.com/0xchasercat/draco/Scraping modern websites has become a massive headache. You basically have two choices: pay for an expensive API like Firecrawl/Browserbase, or run a fleet of headless Chrome instances that eat 1GB of RAM per page and still get blocked by Cloudflare.I built Draco to fix this. It’s a fast, single-binary web scraper written in Rust. You point it at a URL, and it spits out perfectly clean Markdown or structured JSON for LLMs.The secret sauce is that it doesn't just boot a browser for every request. It uses a tiered escalation engine:Tier 1 (Stealth Fetch): Draco uses a custom TLS/JA4 fingerprint to perfectly mimic a real browser's network signature at the packet level. It turns out a lot of anti-bot walls will let you right through if your handshake looks correct. In my benchmarks against sites like Cloudflare and Target, Playwright ate ~500MB of RAM and timed out. Draco bypassed them in under a second using just 20MB of RAM.Tier 2 (V8 Isolate): If it hits a React/Next.js SPA that needs r

Show HN: Kota – Bring AI agent CLIs into the same roomhttps://www.kota.place/A couple months ago, I was tired of keep copy-paste across different Agent Chatbot tabs, feeling like a slave for AI sessions, so I created Kota for my own work.Kota was designed around a concept of Knights of the Round Table.It treats human as part of a project team, and- Runs on top of existing CLIs with existing logins, - Gives each agent a persisted, viewable and editable identity, instead of sessions - Has a file-based long-term memory, - Uses a self-managed skillset, - Works on separated worktrees as workspace, and - Chats directly with other agents in the room.I have been using Kota for my daily work, hobby projects, as personal life assistants and to improve Kota itself, sitting down or on the go.Starting this week, I found it has become the only AI tool I am using now. So I am very happy to release Kota as an open source project, hoping more people can share my joy of living and working with these little friends.In the released version, you can use some most popular CLIs with

Show HN: EvoChess – start with 8 pawns, evolve your armyhttps://penkovsky.github.io/evochess/This chess variant's theme is evolution. One morning in early 2016 I woke up with an idea: what if chess were built around promotion? Eventually, this resulted in the following game:It plays like chess, but you start with only pawns and a king. Pawns can be promoted to bishops or knights, while those minor pieces can be promoted to rooks. Their promotion rights accumulate (every three pawn moves, pawn promotion right; every three minor piece moves, minor piece to rook right). Rooks are transformed to a knight or a bishop on the rook's fifth move.Recently, I built a playable version. The AI opponent works on phone with no internet. The search engine uses a lightweight neural net. The engine was first weak and my friends complained about it.So I have spent quite some time to train a better NN for the board evaluation. Fixed some bugs in search. And I have even designed a "Fun" mode where the AI opponent is thinking while you are thinking. (WARNING: "Fun" mode is ruthlessly draining the b

I'm trying to make somthing worthy of people buying it and getting good value, I have not really shown it off or had anyone look at my site past the occasional web crawler, and I did 100% make this. Its called 0verload and the things it does, I will now list. Automatcially tracks versions on all your source code. It dosnt replace GIT, its for the saves you do between checkins...that one version you should have saved .it does..automatically. even oob writes get a version. I cant live with out it... somthing about telling my llm ....get me that thing I wrote like 2 days ago or a week ago or whenever.you can just tell the llm kinda where when and it will go get it and merge it in....I have files with hundreds of versions and you would think it would be annoying but if you have an llm ...I ship claude skills with it so it wakes up knowing how to use it, AND that brings me to somthing else it does..

Show HN: Vein, a minimalist open-source resource management gamehttps://d2ykijtrvb890q.cloudfront.net/Recently I've been working on Vein, a small open-source resource management game built with Godot.I've always loved resource management board games, and I wanted to see how minimal I could make one. The core idea is simple: keep the heart beating by supplying it with the resources it demands. I tried to strip the mechanics down as much as possible while still leaving room for interesting decisions, and I added a short tutorial to help players get started.The problem is that I still don't feel like I've found the right gameplay loop. It works, but it isn't yet the game I imagined. I'd really appreciate any feedback—whether it's about the mechanics, pacing, tutorial, UI, or anything else that stands out. I'm especially interested in ideas for making the core loop deeper without making the game more complicated.Most of the development was done with Claude Sonnet as a coding partner, while I focused on the design, gameplay, and iteration. The game engine is Godot.You can play it here: http

Show HN: Open OneNote Viewer in Rusthttps://github.com/emsi/OneNoteViewerFor more than 15 years, I accumulated hundreds upon hundreds of notes in OneNote. I loved the application and still consider it one of the best and most distinctive note-taking tools available. Its free-form canvas supports a way of organizing information that Markdown-based tools simply cannot reproduce.The problem was that using OneNote became increasingly inconvenient for me. Microsoft never released a native Linux client, so I kept a Windows VM and later even a separate Windows small PC largely for OneNote. The OneNote Web Clipper for Firefox eventually stopped being supported, removing one of the ways I regularly captured information.The web version did not solve the problem. In particular, it could not search across all my notebooks at once. To find a note, I first had to remember which notebook contained it, which rather defeated the purpose of having a searchable archive. I also found the web application slow and substantially more limited than the desktop client.I looked at al

Show HN: I Built a (Country) Geography Guessing Gamehttps://www.whatcountryisit.com/hi HN,I get mad at myself when I forget the name (or location) of a country, so I built a simple game that's browser based, no login, that I could set my homepage to, that'd quiz me on country names based on the outline location on a map. I didn't like other country geo games cause they just showed the standalone country (outline), without showing where it is on a full (draggable) map. So I thought I'd just make the exact game I want. Made lots of recent updates, and happy so far. See what you think.
