Show HN: TechStacks – Popular Tech news summarized, including commentshttps://techstacks.ioI don't have much free time but still want to keep up with the most interesting tech news, so I added a news aggregator to TechStacks to do the skimming for me.It scans Hacker News and a range of subreddits for the most popular tech posts, tags and categorizes them by topic, and generates a TLDR of the important parts of each article. It also runs a sentiment analysis over the comment threads - which I find just as important as the article itself. The collective hive mind of comments is pretty good at rating how trustworthy a piece is and filling in the context the article leaves out, so the discussion summary often tells you as much as the write-up.The idea is that when you've fallen behind, you can jump into a topic you care about, skim the TLDR and the comment sentiment for each story, and quickly work out which articles are actually worth reading in full.The aggregation is run multiple times a day. Summaries and sentiment are LLM-generated so they're occasionally off - everything lJul 24, 2026 12:16 PM

Show HN: Superkube - Rewriting Kubernetes in Rusthttps://github.com/debarshibasak/superkubeI have embarked on a journey of rewriting Kubernetes into a single binary in Rust, with everything embedded.Architecturally, instead of etcd, it has options to use SQLite or PostgreSQL as a backend. I am trying to make it compatible with Kubernetes APIs, and kubectl should just work out of the box.This is not 100% ready yet, but I just wanted to show the first look. It is almost 90% AI-generated. Claude code with Opus 4.7 is being used here.It should just work out of the box on macOS with Docker as runtime.May 1, 2026 3:08 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

Template for telling the truth on layoffs like at Blockhttps://news.ycombinator.com/item?id=47178248For the people who have been laid off, I think the letter by Jack is a disservice. So I crafted a more direct letter. Hope future letters follow this approach.Today we are making one of the hardest decisions in the history of our company: we are reducing our organization by nearly half, from over 10,000 people to just under 6,000. This means over 4,000 of you will be leaving the company.I want to be incredibly direct with you about why this is happening.The Reality of the DecisionFirst, let’s be clear: you are not being replaced by AI. The technology is not better than you, and it didn't "outwork" you. The truth is simpler and more frustrating: we planned a specific strategic direction, and it didn't work out. We over-extended, and we now need to course-correct to keep the business viable.However, we operate in a market that demands a specific kind of "success" story. If we simply announced that we missed our targets and need to cut costs, the market would react with volatility, punishFeb 27, 2026 8:53 AM

Show HN: Beehive – Multi-Workspace Agent Orchestratorhttps://storozhenko98.github.io/beehive/hey hn,i built beehive for myself mostly. it has gotten to the point where my work consists in supervising oc or cc labor at tasks for multiple issues in parallel. my set up used to be zellij with a couple tabs, each tab working in a separate dir and it was a pain to manage all that. i know i could use git worktrees but they're kind of complicated, if you don't know how to use them it is easy to mess up, and i just prefer letting agents run in separate dirs with their own .git and not risk it. while i like zellij and use it inside beehive, i dont like the tabs and i forget where i am half the time.beehive is a way for me to abstract that away. the heuristic is simple - hives are repos, so you basically have a bunch of hives which correspond to repos you work out of. each hive can have many combs. a comb is a dir with the copy of the repo you're working on. fully isolated, standalone, no shared .git. so for work or for personal stuff, i usually set up the hive, and then have a bunch of Feb 24, 2026 10:41 AM

Show HN: Homemade robot playing piano concert in SF (7/26)https://grayarea.org/event/deru-we-will-live-on/Figured there are probably some folks on here that might be interested in coming to a robot piano concert at Gray Area in SF this Saturday night (7/26). More comprehensive technical write up to come (eventually) but the show is by LA composer Deru (https://deru.la) and features 3 robot/player pianos that sit over the top of traditional upright pianos and are controlled live over USB MIDI by way of an ESP32-S3.The story of how it all came about is kinda long but Ben (Deru) recorded an album (We Will Live On: https://deru.bandcamp.com/album/we-will-live-on), during covid on a Yamaha Disklavier (the album will be performed as part of the concert). To try and work out how we could actually tour the album we found a community of homebrew player piano folks that started with Brandon Switzer's work (https://github.com/bbswitzer/pianoproject) which led to a Discord group (https://discord.gg/vE9uPg2y) and then to Josh Phillips's work evolving it into an over the top player (https://github.com/jJul 22, 2025 6:17 PM

Ask HN: 18 y/o YC founder post-startup – what now?https://news.ycombinator.com/item?id=39966537Earlier this year I left my startup and now have a major gap I don't know how to fill. I've seen many posts on this topic before, but they're all from ~30 year olds in a vastly different place to me (money, connections, degrees).Some context: - I dropped out when I was 15 to spend more time working (at the time consulting for F500s, later climbed to a senior-level job in advertising) and soon after found myself building companies. The first one didn't quite work out, but by 16 I had a good amount of experience in marketing and cofounded an ad agency with a friend (also 16y/o) that we grew to relative success (~500k rev.) - We got into YC, learned VCs don't invest in agencies, pivoted and raised 1.5m from VCs including Paul Graham. Several months in the pivot hadn't landed with users so we gradually whittled down our multicontinental team of 25 (managed by two 16 year olds lol) as we searched for a new idea. - Parallel to this a 3rd company/side hobby (a luxury brand) became extremely pApr 8, 2024 5:41 AM

I spent my twenties bouncing all over the place; did a stint in the Army Reserves while shooting for liutenant bars that didn't work out (failed out of college and I was in ROTC). Did construction, real estate, grew weed in Denver for a year (legally), ended up bartending for roughly a decade. It was great in my early 20s. Not so hot to watch my age group get raises and salary increases.I have my GED and never finished college - left with a record-setting 1.2 GPA (I have severe ADD and I wasn't properly medicated, there were other problems too). Seemed like there was this universe of 'good jobs' that were simply not in the cards.So there I am, in my early 30s, struggling to make NY rent and watching folks get promoted and getting married and buying houses and all that stuff.

We are building an open-source ELT platform that replicates data from any applications, APIs, databases, etc. into your data warehouses, data lakes or databases: https://airbyte.io.I’ve been in data engineering for 11 years. Before Airbyte, I was the head of integrations at Liveramp, where we built and scaled over 1,000 data ingestion connectors to replicate 100TB worth of data every day. John, on the other end, has already built 3 startups with 2 exits. His latest one didn’t work out, though. He spent almost a year building ETL pipelines for an engineering management platform, but he eventually ran out of money before reaching product-market fit.By late 2019, we had known each other for 7 years, and always wanted to work together. When John’s third startup shut down, it was finally the right timing for both of us. And we knew which problem we wanted to address: data integration, and ELT more specifically.We started interviJan 26, 2021 4:08 PM

Launch HN: AmpUp (YC W19) – A reservable electric car charging networkhttps://news.ycombinator.com/item?id=19360572Hi HN,This is Tom from ampUp (https://ampup.io/). We're building a reservable electric car charging network out of shared private and home chargers.As a Nissan Leaf driver without a home charger, charging has been almost a daily headache for me. For many commutes and trips I have to ask myself, should I drive my Leaf, use Uber, take public transit, walk really far, or just not go? This is due to the walk-in-only model of the public charger, which results in unpredictable availability. Worse, public charging is growing at a slower rate than EV adoption, and the range estimators on EVs are no better than a 10-day weather forecast.I used the Plugshare app and it helped some, particularly the couch surfing style of charging where I arrange a 2 hour slot with some home charger hosts. When it worked well, it took out the unpredictability and therefore anxiety. However, it doesn’t always work well. Many times hosts won’t respond to text/calls to make the booking, and a couple times I forgot tMar 11, 2019 5:00 PM
