Show HN: Slack knowledge curator to extract FAQ from discussion threads https://ift.tt/L8jUJiY

Show HN: Slack knowledge curator to extract FAQ from discussion threads Hi HN! Excited to share Snowshoe, a Slack bot that transforms your Slack threads into a searchable StackOverflow-style Q&A. Snowshoe automatically curates key discussions from Slack, creating a dynamic, easy-to-navigate knowledge hub. A lot of technical discussions among engineers happen in Slack threads. Yet the unstructured thread makes its inherent knowledge difficult for search and thus the discussion insights aren’t often well documented & maintained. LLM is surprisingly good at summarization & extraction. Thus I think it’s good timing to give it a try. Currently Snowshoe focuses on knowledge extraction in Q&A format. What’s next? I feel like there would be a lot of value in the auto-curated Q&A, e.g. auto question answering, knowledge hub, Slack archive for SEO. Happy to hear your thoughts! https://snowshoe.dev/ December 21, 2023 at 12:21AM

Show HN: Userscript to improve the readability of deep nested comments on HN https://ift.tt/IGC3rFH

Show HN: Userscript to improve the readability of deep nested comments on HN Hi everyone, I love browsing Hacker News comments on my smartphone, especially the very popular posts with 100s of replies. However the deep nested comments can get hard to read if the text is squashed together on the right side of the screen. My userscript enhances the readability by providing a button to expand the comment to full width. https://ift.tt/wCehpcL December 20, 2023 at 02:01AM

Show HN: Canary Checker – An OSS Kubernetes Native Health Check Platform https://ift.tt/CAkBHsL

Show HN: Canary Checker – An OSS Kubernetes Native Health Check Platform I am Moshe the Founder @ Flanksource, and today we are releasing canary-checker, an open source, kubernetes native health check platform that provides a unified view of health across the entire stack. Canary checker was born out of the need for platform teams (particularly those running on- premise or on less than perfect infrastructure) to understand the health of applications running on top of the platform. Unlike other solutions such as prometheus blackbox exporter, kuberhealthy, and synthetic testing offered by major cloud providers, our approach goes beyond health collection. Canary Checker enables health aggregation by ingesting alerts from Prometheus, Cloudwatch, Dynatrace, and for running full test suites using tools like K6, Playright, Robot, etc.. This approach provides a unified view of system health without the need to browse through many dashboards. Canary Checker can also replace the need for multiple Prometheus exporters. It empowers you to export metrics from responses across 35+ supported protocols, including HTTP, SQL and Elasticsearch. Something fairly unique to canary-checker is the ability to build stateful checks that use the results of a previous check in subsequent checks to generate metrics around historical data such as logs, logins, and activity stored in db tables. https://ift.tt/2cs5RbX December 19, 2023 at 11:44PM

Show HN: Paradict – Streamable multi-format serialization with schema https://ift.tt/SBpqM1Q

Show HN: Paradict – Streamable multi-format serialization with schema Hi HN ! I'm Alex, a tech enthusiast. I'm excited to show you Paradict ( https://ift.tt/fFNU239 ), my solution for streamable multi-format serialization. Although JSON, YAML, and TOML are all human-readable, they serve different purposes. For example, TOML is specifically designed for configuration files while JSON is used as a data interchange format. Sometimes an initiative to create a binary version of JSON arises and as far as I know, it ends with an unidirectional mapping of datatypes. There is no silver bullet, yet one coherent solution built from scratch that addresses multi-format (binary and textual) serialization and configuration files would be a step forward. Earlier this year, I accidentally designed a textual data format to represent complex data structures inside a document divided into sections. The project, namely Jesth (Just Extract Sections Then Hack'em), generated an interesting discussion on HN ( https://ift.tt/wNOk4vT ). Out of curiosity, I ran some benchmarks using Jesth, JSON and MessagePack, with and without Gzip compression against a large JSON file downloaded from the web. The benchmarking gave me insights that led to the decision to evolve Jesth's ideas into a new multi-format serialization solution. I designed and built Paradict from scratch to serialize and deserialize a dictionary data structure. Although Paradict's root data structure is a dictionary, lists, sets, and dictionaries can be nested within it at arbitrary depth. A Paradict dictionary can be populated with strings, binary data, integers, floats, complex numbers, booleans, dates, times, datetimes, comments, extension objects, and grids (matrices). There is also a schema-based validation mechanism that can contain programmatic checkers. The binary serialization format is designed with compactness in mind such as Pi with its first two decimal places, the Golden ratio with its first two decimal places, and the date of the funeral of Pope Benedict XVI would each be encoded on two bytes (not counting their respective 1-byte tag which starts each Paradict binary datum). This binary format has two levels of granularity for continuous data stream processing: a datum at the low level, which is in some cases a 2-tuple composed of a tag and its payload, and the message at the high level which is a dictionary data structure. The textual serialization format has two modes: data and config modes. Config mode implicitly treats dictionary keys as strings, removing the need to surround them with quotes, and unlike the colon (:) between a key-value pair in data mode, it uses the equal sign (=) as separator. This textual format has two levels of granularity for continuous data stream processing: a single line of text at the low level and the message at the high level which is a dictionary data structure. Here is a valid Paradict configuration document that contains a "user" section: [user] # no comment id = 42 name = 'alex' birthday = 2042-12-25T16:20:59Z photo = (bin) 54 68 69 73 20 69 73 20 6E 6F 74 20 61 20 70 68 6F 74 6F 67 72 61 70 68 weight_matrix = (grid) 1 0 1 0 0 1 0 1 1 0 1 0 books = (dict) romance = (list) 'Happy Place' 'Romantic Comedy' sci_fi = (list) 'Dune' 'Neuromancer' epitaph = (text) According to the law of conservation of energy, no a bit of you is gone; you are just less orderly. --- Under the hood, Paradict uses Braq ( https://ift.tt/iHaj2dO ), the most obvious way to section a document (as shown just above), and Ustrid ( https://ift.tt/Xjp1QtO ), to uniquely generate string identifiers. Paradict is available on PyPI and you can learn more by reading its README, browsing the source code or playing with its tests. Let me know what you think about all this ! https://ift.tt/fFNU239 December 18, 2023 at 10:00PM

Show HN: Modern C++ implementations of a words counter with benchmarks https://ift.tt/FdDbRu0

Show HN: Modern C++ implementations of a words counter with benchmarks I uploaded a few days ago some code I had around that some people could find interesting, so I share it here. It is a series of increasingly more performant C++20 words counters (though quite simple in the definition of what a "word" is). Feel free to experiment. Things should be ready to use in Linux and Mac. If you find any problems building, please let me know through Github, I do not have much time but when I find a slot I will correct at least user failures. Planning to add a decent `./bootstrap.sh` to speed up dependencies installation by users. https://ift.tt/DaApmOo December 17, 2023 at 01:09AM

Show HN: Sqlauthz: Declarative permissions management for PostgreSQL https://ift.tt/PkjQScx

Show HN: Sqlauthz: Declarative permissions management for PostgreSQL I've been working on a little project recently to solve a problem that I've encountered at every job I've ever had, and I'm eager for some feedback. Having super granular roles & permissions in PostgreSQL is desirable, but quite difficult to maintain (particularly at smaller companies without dedicated security/devops/DBA/whatever who make it their business to maintain it). I've thought for a while that having a declarative way to manage them would be really useful and allow more teams to actually make use of sophisticated security features that PostgreSQL offers in their production systems. You can probably see where this is going... I wrote a tool to do just that! It's called sqlauthz, and it allows you to declarative manage your PostgreSQL permissions by writing rules in the Polar authorization language. https://ift.tt/mWO3wSb December 17, 2023 at 12:42AM

Show HN: Genji – AI browser ninja that can complete any task on Chrome https://ift.tt/IsuydSk

Show HN: Genji – AI browser ninja that can complete any task on Chrome Hey folks, so I built a chrome extension called Genji, an AI assistant that automatically completes your browser tasks for you. You simply enter your task, and Genji uses GPT-4V to figure out the best browser action to perform next repeatedly until the task is accomplished. The idea is that you can delegate your personal tasks like online shopping or making reservations to Genji. You can also use him professionally to find leads on LinkedIn, send status updates to your boss, or research your competitors and write an analysis document. I’m wondering if you would use Genji as part of your daily routine? Would he be more useful in a personal or professional setting? What concerns do you with using a productivity tool like this? I'm also planning to add voice support and the ability to schedule tasks soon. Do either of these features interest you? If you want to try Genji, download the chrome extension and let me know what you think. It's completely free with no sign up required! https://www.genji.app/ December 16, 2023 at 03:13AM
