Show HN: An MCP server that turns async-work practices into toolshttps://github.com/open-and-async/mcpMore than a decade ago, I adopted the self-imposed rule, if I answer a question more than once, the third time I need to be able to answer with a URL. Today, I published one very large URL - a book distilling what I learned from helping people work remotely at GitHub, and I wanted to rethink my rule for the age of AI.What if, instead of a URL, I could create an interactive experience that could tailor the guidance to your particular situation?What I ended up building was an Open and Async Advisor MCP server. To install (in claude or any other AI):> claude mcp add open-async -- npx -y @open-and-async/mcpTransparently, yes, it's from a book I wrote which launched today, but the MCP server is open source and free to use. No purchase required. It knows the key principles of the book, and has specialized tools like `draft_decision_doc`, `convert_meeting_to_async`, `score_status_update`, `triage_sync_vs_async`.This is an experiment for me, and I'm genuinely curious if it's helpful for othersJul 21, 2026 4:06 PM

Ask HN: I stopped fighting AI over-reliance and built a workflow around ithttps://news.ycombinator.com/item?id=48979474I am a frontend engineer and actively use AI. I caught myself that i never write code manually, only if i have to tweak some styling. I feel lazy and dumb compared to pre-AI era. Even if i have to write some small changes in code that take like 2 minutes - it is easier to spend those 2 minutes explaining everything in details to AI and point out what and how it needs to change. Because i dont have to think about the process, i only explain the idea and desired solution - then wait until its done to review.Thats some kind of degradation. But the thing is that the quality is amazing. My productivity and speed increased significantly.But there is a frustrating thing. The laziness started affect even review process. I feel like i dont want to spend time to read and check all the changes - i will better ask another AI to do it. And it works! I use Claude for like 95% of work, then switch to GPT to review everything properly. They have different personalities so you have different points of Jul 20, 2026 2:35 PM

It's a more in-depth gig than you'd think.My family and I bought an abandoned 8-lane bowling center in the rural mid-west. In our small town there weren't many recreation options for families. You've heard of a food desert? This is an R&R desert.It had been abandoned for a good reason. The roof leaks, the electrical system was constantly surging, and my 70-year-old bowling equipment (still) doesn't work perfectly. The system that keeps your score is particularly interesting to me. It's the thing you watch during your game, but it fades into the background beyond that. Turns out these things are really cool, but absurdly expensive.Ours was installed in 2008 and cost six figures. It's calculating ball speed and trajectory, camera-based pin detection (object detection and trig, on ICs!), runs the fouling, the animations, the pinsetting machine and ball return. Very cool stuff for its age.From the business perspective, my faciliJul 19, 2026 2:41 PM

Ask HN: Does a local, Git-backed LLM "compiler" for personal notes make sense?https://news.ycombinator.com/item?id=48968447Back in 2012, my very first startup was a note-taking and document storage app. Think Evernote meets Google Drive, but with a much faster UI. We managed to claw our way up to 1,800 active users. Then Google announced 25GB of free storage for Drive, and overnight, our business model evaporated. We had to shut down the company.I've been through the startup ringer four times since then. Despite the explosion of knowledge management tools over the last decade, I still manage almost my entire life and todo list in a single Markdown file. I’ve grown to severely distrust SaaS note-taking apps. I don't want my second brain held hostage by a monthly subscription, and I don't want it locked in a proprietary database.I'm thinking about building something new in this space, completely free and open-source, and I want a sanity check to see if anyone actually cares about this approach.The Idea: A lightweight, native desktop and Mac/Windows app that acts as an "LLM compiler" for your local files (insJul 19, 2026 2:20 PM

I get a response in 10 seconds and its long and well detailed. I ask claude, it wastes my tokens talking to itself, makes insulting stupid and frankly rude shortcuts that have no basis in reason except for Anthropics profits...Its unuseable. It will just cough up a half complete reaponse, deciding to strip everything out of value...place nothing useful in, leave half finished files and then worst of all...it doesnt even putput them and leaves them in its own private memory...until you ask for them explocitly and it regenerates rhem again at full cost....its just pure fraud.

Show HN: Vulnsy – A platform for vulnerability management and reportinghttps://www.vulnsy.comI've spent over 10 years doing penetration tests and red team engagements, and one thing that always seemed to take far longer than it should was reporting.Most reporting platforms do a great job of managing reusable findings, but I still found myself digging out old reports and copying the same narrative sections over and over again.Many engagements contain pages describing methodology, attack paths, privilege escalation and post-exploitation that only need small changes between clients. I wanted those sections to be just as reusable as findings.I built Vulnsy to make the entire report reusable. Alongside reusable findings, you can build libraries of narrative sections, assemble reports quickly, customise them for each engagement and export professional reports without copying content between Word documents.There's lots more you can do too..Jul 17, 2026 11:02 AM

How Google decided to Destroy its Search Monopolyhttps://news.ycombinator.com/item?id=48945074This is a bit of a rant, yet it's one I think is rightly deserved.Over the last several months, Google has exploded with:* extreme delays in rendering search results* popups of captcha + prove you're human, for simple searches* extreme delays in doing anything after hitting enter on searchInstead of taking 100ms or less to return search results, it now takes 5+ seconds, 10+ seconds sometimes. Often with a captcha in between.This 100% isn't me. I've noticed these changes, discussed with others, and it's happening to people across a wide swath of industry, and situations. Co-workers at home. Elderly parents. People at workplaces. The list goes on.This is worst at night, and of course that's when I tend to work the most. It's so bad, that once I see that first captcha, I just switch to Bing. Yes, Bing. Kagi works, but from where I sit its results have been sliding and slipping, sadly. I don't know what they've been focusing on at Kagi recently, but it's not what it once was. Likely, reliaJul 17, 2026 9:19 AM

We're Giacomo and Roberto, authors of Ratel (https://github.com/ratel-ai/ratel)We used to help SaaS companies build agents on top of their products. Whenever we wanted to expand the agents’ complexity/scope, by adding more and more tools and instructions, we always run in the same issue: context bloat, with frequent hallucinations and sky high token bills. So we started constantly engineering the agents, dynamically loading tools, splitting them into subagents, inventing our own way to support skillsAnd that's exactly when we started building Ratel: a library to let your agent keep its full catalog of tools and skills, but progressively disclosing only the few that actually matter for each turn. Now you can grow your agent's capabilities without breaking it or taking out a loan for itPeople are already using it in production, with a user cutting their token cost up to 81% in the first month without compromising the accuracyWe support both keyword and semantic retrieval, all in-pJul 16, 2026 4:11 PM

I want to pop up a new tab, start writing my thoughts and, maybe, share them over the internet. As fast as I can and with as little friction possible. tldraw totally does this for drawing stuff in a whiteboard but for text, Obsidian is a local tool that requires installing and Notion is too involved. I want a simple link that just works the moment you navigate to the page.2. Sometimes I wanted to share code or other text artifacts with customers over Discord, but the platform caps messages to a certain length before it forces you to submit a .txt. Pastebin kinda fills this gap but it's an old site and it doesn't handle BIG pastes very well also it doesn't double as your own document vault (plus I don't care about all their "public pastes" thing).3. This is a recent one. Now, due to AI tools, everyone is sharing MarkdoJul 16, 2026 2:26 PM

Show HN: Pokayoke – turn code conventions into checks for agentshttps://pokayoke.codesHey HN,Something I've been tinkering with in the background is a system to manage the "messy-middle" of TypeScript toolchains. Quite often, when I'm using Biome or any of the other linter / formatters, there will be repo conventions that I want to enforce (especially with AI agents), but which aren't supported by them, such as:- Enforcing lines-of-code limits in modules - Never using custom TailWind colors - Only using lowercase underscores in filenamesLike, this is quite "random" but also bread-and-butter stuff that it's easy to think or talk about when you're working by yourself or with a few other human teammates, but I've found that agents consistently miss these conventions if I put them in an AGENTS.md file for example.I wanted to make my esoteric repo conventions less stochastic, and more deterministic. I realised that agents are adept at writing the kind of code needed to run arbitrary checks on the TypeScript AST or workspace environment -- the kind of code that is cumbersome Jul 16, 2026 9:40 AM

In my 20s there were a group of 12 of us, who shared a whatsapp group and every thursday, we had a standing appointment to decide and watch the interesting movie for the week.Over the years as life happens and folks got married, moved, priorities shifted, that ritual that almost lasted a decade fell apart.During the pandemic, given that most of us had a VR headset, we reconnected and started watching movies together - we'd setup a shared stream and would have a google chat going on the side, so that we can hear each other while the movie played.VR has been surprisingly good to recreate that theatrical atmosphere - but the worst bit is sitting in a virtual cinema as the only person. Dimming the lights out (within the virtual environment so that you don't see the empty chairs) and having a video call where we can hear each other on one of the ears, kinda felt a bit like the gang was back together.Even if it hasn't beenJul 16, 2026 8:06 AM

Show HN: Running server scripts from smartphone via SSHhttps://c100k.eu/p/rebootx/updates/20260714-remote-runbooksI've added Remote Runbooks to RebootX, a mobile app for managing cloud and on-prem infrastructure, available on iOS and Android (freemium).The idea is simple: when PagerDuty wakes you up, many incidents boil down to executing the same sequence of SSH commands or operational steps. Instead of opening a laptop, you can execute a predefined runbook directly from your phone.Very usefyl when you're on the go.The scripts are retrieved from the server at `/usr/local/sbin/rebootx/runbooks`, also via SSH. If a script is prefixed with `__` (2 underscores), it's considered dangerous and the app warns you about it and ask for confirmation before executing it.Some will argue that with the perfect infra, you don't have to do all of this. By experience, none of us have the perfect infra so SSH-ing into the server (e.g VPS) is often required.Happy to hear about your feedback or ideas of improvement.Jul 15, 2026 1:30 PM

It started as a different project because I wanted to make my portfolio website editable without writing code and keeping the freedom to build any layout. But, while doing so, things evolved and the idea of making it a Headless platform for e-commerces started growing. That's when I went all-in and fired myself from my previous job and spent countless hours building (and re-building) it. You have a lot of freedom here: - You can no-code your website with the drag & drop editor and host it. - You can build custom React components in the very same editor, straight from the browser, installing any NPM package and using Tailwind. You also have access to an integrated SDK for e-commerce functions (like cart management, user auth sessions, checkout start, etc.) - You can leverage the public APIs documented at https://docs.webround.com to build virtually anything: integrations, custJul 15, 2026 8:59 AM

When you click on the new tab, only the first tab loads in background, the rest will have a placeholder until you click. 2. Only 3 active tabs per window are allowed to be loaded, the rest will be killed. 3. The extension watches if you have unsaved input, paused or active media, or if the page is configured to send notifications and it keeps these tabs alive.I've been using it for a couple of weeks and it allows me to open way too many tabs to handle :)The extension is published in Chrome Web Store, let me know if you have any questions!Jul 14, 2026 4:14 PM
