Show HN: Unlogged – open-source record and replay for Java https://ift.tt/VPW49U0

Show HN: Unlogged – open-source record and replay for Java Hello HN! Parth, and Shardul here. We have been building unlogged.io for the last 21 months. We started as a time travel debugger and pivoted to record and replay with assertions, mocking, and code coverage. You can save the replays in the form of a JSON and commit them to your git. Both Parth and I come from an e-commerce/payments background where production bugs meant heavy financial losses. Big billion days/Black Friday sales meant months of code freezes with low productivity. Before committing the code, we wanted to replay production traffic and know the breaking changes right away, like in sub-second. Kind of like unit+integration tests on steroids. So, we built an SDK that adds probes to the code in compile time. The SDK logs code execution, in detail. Git: https://ift.tt/MWnc3Dm We also built an IDE plugin that keeps monitoring code changes, hot reloads these changes, replays the relevant methods, and alerts on failing replays. It also lets developers call Java methods directly, mock downstream methods in run time, highlight code coverage in real-time, and show performance numbers for methods with inlay hints. (right above each method) Git: https://ift.tt/IySsbic We are excited to launch the first version of our product that replays with assertions + mocking + code coverage reports right inside the IDE.

Create a production logger -So that the performance impact is minimal -out of the box masking PII from production logs -creating meaningful input/return value combinations from production traffic to be replayed locally. 2. Creating a CI test runner that can integrate with CI/CD pipelines. 3. Auto-Replaying API endpoints of only the changed code. 4. Real-time alerts for the performance impact of code changes. 5. Creating a dashboard with reports, email/slack alerts. October 30, 2023 at 09:47PM

Show HN: I made a trivia game for fellow movie lovers https://ift.tt/zidIgns

Show HN: I made a trivia game for fellow movie lovers This is for those who, like me, are cinephiles. You just need to ask questions and try to guess the movie's name that ChatGPT picked. It's a great game to exercise your brain and memory. Give it a try and let me know what you think (: https://movieguess.com/ October 31, 2023 at 12:23AM

Show HN: Launch a private Ethereum Testnet with all clients and MEV infra https://ift.tt/K2o8WlA

Show HN: Launch a private Ethereum Testnet with all clients and MEV infra We've been working with the Ethereum Foundation & Flashbots to build tooling and infrastructure for developers to test various workflows for Ethereum. As part of that work, anyone can now spin up a local Ethereum dev net with the entire Flashbots mev-boost infra (relayer, builder, boost) using the ethereum-package. This package supports all EL and CL client types, works on Kubernetes for scale testing, and comes with a few bells and whistles like metrics, mock-builders, and beacon chain explorers. This is the de-facto tool for teams modifying and testing the consensus layer. Here's a full tutorial - https://ift.tt/8DATVkO... https://ift.tt/HFyniMV October 30, 2023 at 11:22PM

Show HN: I’m writing a “US Banking and Credit for Foreigners” guide https://ift.tt/pgMsDkR

Show HN: I’m writing a “US Banking and Credit for Foreigners” guide So I’m writing a guide about accessing US Banking & Credit as a non-US resident. It’s work-in-progress but the first couple of chapters are accessible for everybody. Any feedback is appreciated! https://ift.tt/q9y1Yds October 30, 2023 at 01:08AM

Show HN: Newslater – A Personal Newsletter Generator https://ift.tt/eDUpcSt

Show HN: Newslater – A Personal Newsletter Generator Inspired by my ability to collect articles from HN that I wanted to read, but never getting around to reading them, I built Newslater. You add the articles you want to read to your reading list, and Newslater will email you a newsletter containing summaries of 5 of your articles sent at a time you choose. My aim was to create a tl;dr newsletter from articles you are actually interested in. The app is free, has no ads, and is available on Android and iOS: https://ift.tt/sCxwZ6P https://ift.tt/tDka6Sm It’s a bit rough, but I thought some others may be interested in giving it a go. You can see examples of the newsletters it generates here too https://newslater.co/ October 29, 2023 at 09:33PM

Show HN: Yet another HN UI clone (sorry) https://ift.tt/BUKEJGF

Show HN: Yet another HN UI clone (sorry) Inspired by https://ift.tt/qwmdeLQ , this is done sort of as a learning journey since I've never built an app from scratch using Next.js and tailwindcss before. This is done over 2 days so it's quite bare in terms of features i.e. read-only but I would still like to share this project. Let me know what you guys think and feel free to provide any feedback! https://ift.tt/lyuW9nK October 29, 2023 at 11:13PM
