Show HN: CounterDB, to persist your likes/dislikes counts https://bit.ly/3Bw1JFs

Show HN: CounterDB, to persist your likes/dislikes counts A Solution to durably store your counts. For example number of likes/dislikes on a post. Its time complexity is O(1). Single header only C++ file for storing and retrieving numbers. It does this without increasing the file size, as its not append only DB. Which also means it can be slower on simultaneous writes to an index. Well if your task is just to store likes/dislikes counts, than it must not be much of a problem. As reads are done more than writes for such cases. https://bit.ly/3MaHGl2 May 17, 2023 at 06:50AM

Show HN: Taskspace – Beautiful, simple, and customizable personal task manager Hello HN. I built a personal task manager https://bit.ly/3Buv1V4 to experiment with NextJS. Wanted something simple and clean that I could keep open in the browser while I work. Added in task history viewing for easy reference during daily standup and when I need to summarize my completed work throughout the year during performance reviews. Now opening to the public to get feedback and see if folks find the app useful. Wondering If I should invest time building out additional features or if I should continue using it only for my personal workflow. Thanks, Tyler https://bit.ly/3Buv1V4 May 17, 2023 at 04:52AM

Show HN: Legend-State 1.0 – The fastest React state library After almost a year of development and iterating, we just released Legend-State 1.0. It's the fastest React state library and is very easy to use, based on Observables (Signals) with fine-grained reactivity and built-in persistence. I'd love to know what you think, and I'm also happy to answer any general JavaScript performance questions if you want since I've gone very deep into optimizing . https://bit.ly/42CmdYV https://bit.ly/44XTvUh May 16, 2023 at 12:06AM

Show HN: Capillaries: Distributed data processing with Go and Cassandra https://bit.ly/3Id2RBN

Show HN: Capillaries: Distributed data processing with Go and Cassandra I started thinking about this approach after working on a large-scale project for a major financial company where our group developed a distributed in-house data processing solution. On a regular basis, it ingested a few gigabytes of financial data and, within a tight SLA time limit, produced a lot of enriched/aggregated/validated data for a number of customers. Sometimes, source data had errors, so operators with domain knowledge had to verify data validity at some checkpoints, immediately make corrections, and re-run parts of the workflow manually. The solution involved complex web service orchestration, custom database and was very demanding on the infrastructure availability. Capillaries is a built from scratch, open-source Go solution that does just that: ingests data and applies user-defined transforms - Go one-liner expressions, Python formulas, joins, aggregations, denormalization - using Cassandra for intermediate data storage and RabbitMQ for task scheduling. End users just have to provide: - source data in CSV files; - Capillaries script (JSON file) that defines the workflow and the transforms; - Python code that performs complex calculations (only if needed). The whole data processing pipeline can be split into separate runs that can be started independently and re-run by the user if needed. The goal is to build a platform that is tolerant to database and processing node failures, and allows users to focus on data transform logic and data quality control. “Getting started” Docker-based demo calculates ARK funds performance, using EOD holdings and transactions data acquired from public sources. There are also integration tests that use non-financial data. There is a test deploy tool that uses Openstack API for provisioning in the cloud. https://bit.ly/42Xd8d1 May 16, 2023 at 01:13AM

Show HN: Tack, a fast lightweight scripting language for games and embedding https://bit.ly/3MpSxc1

Show HN: Tack, a fast lightweight scripting language for games and embedding https://bit.ly/3W4IIU6 Hi HN! Tack is a scripting language I've been working on sporadically for the past year or so, and intensely for the past few weeks. It originated out of a desire for something that was like Lua, but with a more familiar syntax, and without some of the other surprises in Lua such as the 1-indexed tables. It's also been a great learning project, and a very satisfying challenge! While the current version is early beta at best, I hope to continue working on it and maybe see some adoption. Despite the relative lack of optimization, I'm very pleased with the performance so far - although I haven't done a huge amount of benchmarking, it seems to be significantly faster than the stock Lua 5.4 interpreter for the quicksort test, and the btrees test (copied from the Computer Language Benchmarks Game). The language is designed for embedding in C++ programs, and is written in C++ more or less from scratch including the handwritten recursive descent parser, and a register-based compiler/interpreter. The only dependency other than the standard library is my C++ adaptation of the khash library used for the object type - a from-scratch hashmap seemed not worth the trouble. Quick code example - more examples in the repo! fn quicksort(arr) { const n = #arr if n <= 1 { return arr } " find the midpoint " let l = min(arr) let r = max(arr) if r == l { return arr } const mid = (l + r) / 2 " split array into upper and lower " const upper = filter(arr, fn(x) { return x < mid }) const lower = filter(arr, fn(x) { return x >= mid }) " recursively sort the upper and lower sub-arrays and join the result" return quicksort(lower) + quicksort(upper) } let A = [] for i in 0, 1000000 { A << random() } let before = clock() let B = quicksort(A) let after = clock() print("Time taken: ", after - before, "seconds") Building requires just cmake and a C++20 compiler - tested with MSVC 2022, g++11 on WSL and Clang 15 on M1 https://craftinginterpreters.com was a great help with implementing closures, as I had gone down a blind alley with my first approach for locating the closed-over variables. However I have taken a slightly different approach towards boxing. As I do intend to use this for some small games myself going forward, there is a standard library already, and plans to expand it. I also intend to release a GLFW-based mini game framework along with precompiled binaries, so hobbyists (and younger relatives!) may use it without needing a full compiler toolchain. I would love if anyone is interested enough to try it out! James https://github.com/PlumeCat/tack May 14, 2023 at 06:39PM

Show HN: WhyBot, making GPT-4 question itself https://bit.ly/3BrvreR

Show HN: WhyBot, making GPT-4 question itself Hi HN — we’re John and Vish! We built WhyBot, a tool to help you deeply explore a question or topic. You ask a question, and WhyBot responds by building an ever-expanding knowledge graph. It does this by recursively generating answers and follow-up questions. You can change its persona to change the flavor of the generations (try toddler mode!). We originally built this for the AngelList Agent Hackathon ( https://twitter.com/AqeelMeetsWorld/status/16502799744050421... ) and got a lot of interest from folks asking to play around with it. So we thought it’d be fun to brush it up and release it as a web app! It’s a work in progress and we plan on adding more features, such as saving, sharing, focusing on one branch and potentially executing code. We hope you enjoy playing around with it and would love to hear any of your feedback or thoughts. https://bit.ly/3O3iBeg May 14, 2023 at 05:17AM

Show HN: Emacs major mode for editing QuakeC files As a part of my personal Quake Renaissance I decided to fulfil my childhood dream of making a mod for the game I played 25 years ago. Surprisingly, I discovered there was no Emacs mode available for QuakeC! So I came up with one. It currently mostly supports Vanilla QuakeC and assumes FTEQCC as a compiler but given some interest I am more than happy to add as many features as necessary for a modern Emacs experience. https://bit.ly/3W3qO4g May 13, 2023 at 10:12AM
