Show HN: A tool that explains any human behavior as Robert Saplosky would do it I'm a big fan of Dr. Saplosky and his book Behave. He talks about how we need to look at any human behavior holistically to understand what really happened rather than looking for simple explanations. But it's hard for us to think like that. So I built this small tool that helps us get started. https://ift.tt/4oxyQbq July 15, 2023 at 10:48AM

Show HN: I built a tool to download your chess games Hi HN, here is my humble weekend project. I couldn’t find any similar utilities online that would let me download all of my chess games, so I decided to make one. It’s definitely imperfect, so please let me know if you have any feedback! https://ift.tt/12eOytx July 15, 2023 at 05:06AM

Show HN: Mark Zuckerberg is doing a live AMA on Twitch (AI) Hey HN! I built a 24/7 Twitch stream where an AI clone of Mark Zuckerberg is doing a live AMA with the chat lol. Twitch: https://ift.tt/6SwNxMd You can ask Zuck any question in the chat, and he'll answer you live. About a day ago, I also built a 24/7 interactive livestream of "Paul Graham" doing an AMA on twitch: https://ift.tt/Ny5TrBm Have fun! :D https://ift.tt/6SwNxMd July 14, 2023 at 07:15AM

Show HN: CodSpeed – Continuous Performance Measurement https://ift.tt/AXYMgqa

Show HN: CodSpeed – Continuous Performance Measurement Hi HN! We’re Arthur and Adrien from CodSpeed. We’re building a tool measuring software performance before any production deployment, catching performance regressions before they hit production environments and reporting performance changes directly in Pull Request comments. It’s kind of like Codecov but for performance measurement. Today, the go to solution to measure performance is probably to use an APM(DataDog, Sentry, …), continuously analyzing your production environment. However, since those solutions are operating on real environments they need real users to experience poor performance in order to report issues and unfortunately, performance remains an afterthought appearing only at the end of the development cycle. Another possibility to measure performance is to create benchmarks while developing and to run them on a regular basis to have an idea of the performance trend of your project. However, with this approach, the variance in the results creates a lot of noise and it’s rarely possible to compare your results with the ones from a co-worker or a production environment. To make consistent performance measurement as easy as unit testing and fully integrated in CI workflows, we chose a benchmark based solution. And, to eliminate the usual variance associated with running them, we measure the number of instructions and memory/cache accesses through CPU instrumentation performed with Valgrind. This approach gives repeatable and consistent results that couldn’t be obtained with a time based statistical approach, especially in extremely noisy CI and cloud environments. We have been in closed beta for a few months, already being used by popular open-source projects such as Prisma and Pydantic. Notably, CodSpeed helped Pydantic through their Rust migration, empowering them to make the library 17x faster: https://ift.tt/JmPz4Gs... Today, we’re super excited to finally make the product available to everyone. We currently support Python, Node.js and Rust and are looking forward to integrate with more languages soon. The product is and will be free forever for open-source projects. Also, we have a per-seat pricing for private repository usage. We have a lot of exciting features planned regarding additional integrations, such as Database and GPU integrations that should come in upcoming months. Don’t hesitate to try out the product and give your honest feedback. We’re looking forward to your comments! https://codspeed.io/ July 11, 2023 at 08:32PM
