Show HN: Three backtested quant strategies as Jupyter notebookshttps://mattitude8861.gumroad.com/l/QuantStrategyTemplatesBundleI've spent a few years building quant strategies and most of the work isn't the math — it's the plumbing: getting clean data, structuring the backtest so it doesn't look at the future, generating a readable tearsheet. I packaged three of my working strategies as self-contained notebooks so someone can go from zero to a proper backtest in an afternoon.The three strategies:1. Funding Rate Carry — Goes long assets with consistently negative funding (market paying you to hold) while hedging directional exposure with a small short on a correlated index. Data from Binance public API, no account needed.2. Momentum + Regime — Standard cross-sectional momentum with a regime filter. The regime filter uses a hidden Markov model to identify high/low volatility regimes and sizes positions down during risk-off states. This cuts most of the drawdown that raw momentum has during trend reversals.3. Vol Mean Reversion — Trades the VIX term structure spread (VIX3M/VIX ratio) against realized vol. Core id

Show HN: Tip for users with Samsung Galaxy S7 with broken displayhttps://news.ycombinator.com/item?id=47770272In 2016, I decided to spend about $800 (€700) on an upper mid-range phone for that time: the Samsung Galaxy S7. Years later, I replaced the battery with one bought on AliExpress, and it didn’t satisfy me. I also dropped the phone and replaced the screen simply because I was attached to that model—it felt much higher quality to the touch than more modern devices. I wanted it like when I first bought it: pristine. I promised myself I’d use a case and replaced its “Super AMOLED” screen. This replacement didn’t satisfy me either. It was done at an out-of-warranty repair service, and the screen quality wasn’t the same as the original. Moreover, this process caused the battery to move around inside the phone. My son dropped the S7 a second time. That case didn’t live up to its promise. I had backups of the data, but something still left me unsatisfied—I couldn’t go through a proper “mourning” for its sudden, total screen failure. But I decided it was time to move on. A couple of years later,

Tell HN: Fiverr left customer files public and searchablehttps://news.ycombinator.com/item?id=47769796Fiverr (gig work/task platform, competitor to Upwork) uses a service called Cloudinary to process PDF/images in messaging, including work products from the worker to client.Besides the PDF processing value add, Cloudinary effectively acts like S3 here, serving assets directly to the web client. Like S3, it has support for signed/expiring URLs. However, Fiverr opted to use public URLs, not signed ones, for sensitive client-worker communication.Moreover, it seems like they may be serving public HTML somewhere that links to these files. As a result, hundreds are in Google search results, many containing PII.Example query: site:fiverr-res.cloudinary.com form 1040In fact, Fiverr actively buys Google Ads for keywords like "form 1234 filing" despite knowing that it does not adequately secure the resulting work product, causing the preparer to violate the GLBA/FTC Safeguards Rule.Responsible Disclosure Note -- 40 days have passed since this was notified to the designated vulnerability email (s

Ask HN: What funding models exist for a search engine?https://news.ycombinator.com/item?id=47767117Let's say I wanted to build a web scraper + search engine product that did not feature ads at all. What other funding models exist? How viable are they?In particular, what if you sold anonymized data about trends/insights into consumer behavior to other businesses? At scale, is it conceivable that such a strategy would be profitable?Under this model, the search results would be incentivized to be as accurate as possible. There would be incentives against influencing rankings to maximize profits (which differs from the classic display ads and the Google Ad Words models) because you would want your understanding of consumer behavior to be as untainted as possible.Thoughts?

Show HN: Kontext CLI – Credential broker for AI coding agents in Gohttps://github.com/kontext-dev/kontext-cliWe built the Kontext CLI because AI coding agents need access to GitHub, Stripe, databases, and dozens of other services — and right now most teams handle this by copy-pasting long-lived API keys into .env files, or the actual chat interface, whilst hoping for the best.The problem isn't just secret sprawl. It's that there's no lineage of access. You don't know which developer launched which agent, what it accessed, or whether it should have been allowed to. The moment you hand raw credentials to a process, you've lost the ability to enforce policy, audit access, or rotate without pain. The credential is the authorization, and that's fundamentally broken when autonomous agents are making hundreds of API calls per session.Kontext takes a different approach. You declare what credentials a project needs in a .env.kontext file: GITHUB_TOKEN={{kontext:github}} STRIPE_KEY={{kontext:stripe}} LINEAR_TOKEN={{kontext:linear}} Then run `kontext start --agent claude`. The CLI authenticates you via

1% Vacancy, 81% Preleased: Where Midmarket Compute Deploys in 2026https://news.ycombinator.com/item?id=47764058The 81.5% prelease rate is the number that should concern mid-market buyers. Hyperscalers are committing to supply before construction starts. When 81% of a building is already spoken for before ground breaks, the remaining 19% gets priced to reflect scarcity.The 1-10 MW segment is in a genuinely difficult position. Too small to compete for primary market allocations, too large for normal colocation pricing, and the usual fallback of secondary markets has its own capacity crunch now. Secondary market lead times are running 18-24 months.The practical result is that companies needing 2-5 MW in the next 12 months have limited options. They're either committing to 10 year deals on space that doesn't exist yet, or they're looking at purpose built alternatives.

Show HN: Early Reader – Free open source reading app I built for my 4-year-oldhttps://github.com/melvinmt/early-reader-appOver the holidays I went looking for a reading app for my 4-year-old daughter. The top app in this space charges $500/month. Since that's a bit much to pay for an app, I figured I could vibe code something better in a few days, so I tried.The app uses DISTAR phonics, which is a method from the 60s by Siegfried Engelmann. The core idea is simple: teach sounds before letter names, then blend sounds into words, then words into sentences. There's a specific sequence that builds on itself.On top of that I added spaced repetition, same algorithm as Anki. Cards come back at increasing intervals depending on how well the kid does. This keeps sessions short, maybe 5-10 minutes, and the retention is noticeably better than just drilling the same set of cards every day.Each card has an AI-generated illustration and spoken audio. All 721 cards are pre-generated and bundled with the app. Nothing calls an API. The whole thing works offline.What's in it: 721 cards (letters, digraphs, words, sentences)
