Show HN: OpenObserve – Elasticsearch/Datadog alternative https://ift.tt/KPmL5DV

Show HN: OpenObserve – Elasticsearch/Datadog alternative Hello folks, We are launching OpenObserve. An open source Elasticsearch/Splunk/Datadog alternative written in rust and vue that is super easy to get started with and has 140x lower storage cost compared to elasticsearch. It offers logs, metrics, traces, dashboards, alerts, functions (run aws lambda like functions during ingestion and query to enrich, redact, transform, normalize and whatever else you want to do. Think redacting email IDs from logs, adding geolocation based on IP address, etc). You can do all of this from the UI, no messing up with configuration files. OpenObserve can use local disk for storage in single node mode or s3/gcs/minio/azure blob or any s3 compatible store in HA mode. We found that setting up observability often involved setting up 4 different tools (grafana for dashboarding, elasticsearch/loki/etc for logs, jaeger for tracing, thanos, cortex etc for metrics) and its not simple to do these things. Here is a blog on why we built OpenObserve - https://ift.tt/LjexUBV . We are in early days and would love to get feedback and suggestions. https://ift.tt/TiJHmUL June 11, 2023 at 04:05PM

Show HN: Yo.link – Subdomain based URL shortener https://ift.tt/M6BkLe1

Show HN: Yo.link – Subdomain based URL shortener I was looking for a pet project to try out recent additions to https://vercel.com platform, specifically their PostreSQL and Redis offering. They also provide easy to setup wildcard subdomain HTTPS certificates, and since I had yo.link domain lying around for a while, why not use it to create, yes, yet another, URL shortening service, but with a twist... Putting the user-selectable short-code in the subdomain has the advantage that it is the first thing that users read in a URL, and as such it is an opportunity to provide some contextual information about the link. Here are some examples: https://svelte4.yo.link --> https://www.youtube.com/watch?v=AOXq89h8saI https://hn.yo.link --> https://ift.tt/WUm12Nt https://ift.tt/ULG67lE --> https://ift.tt/it7QY2N... I couldn't find any other shorteners that use this approach, hence wanted to build one. Redis is great for counting realtime clicks, sliced by hour, day, month, country/city and user browser. PostgreSQL is used as master DB to host the short-code destination-link mapping, and for user management. I plan to add some extra features, like: - tagging the links so it is easy to search and categorise. - password protect the links. - separate analytics for QR code visits. Please let me know what you think. Any ideas, suggestions or critic is very welcome. If you are interested in collaborating on such a project, please let me know (support@yo.link) https://yo.link June 11, 2023 at 03:29AM

Show HN: A music search engine that helps you find new songs https://ift.tt/St1OR0e

Show HN: A music search engine that helps you find new songs Just finished working on a side project that helps you find new music by searching through various criteria and at the same time play the songs that fit your filters. I often find myself stuck listening to the same few songs as finding new ones can be a long and sometimes fruitless process. That is why I wanted to make a tool for anyone to use that takes into consideration multiple parameters that have to do with a song, with all the filters coming from the user with no ads or popularity of songs affecting the search. I am 19 and love working with programming projects like these in my free time. Play around with the product and feel free to provide any feedback on it! (Note: As most streamlit URLs it may need to be copy-pasted in the search bar to work.) https://ift.tt/QbYHulK June 10, 2023 at 02:44PM

Show HN: I turned my email automation tool into a full-fledged email platform https://ift.tt/wSnZFVt

Show HN: I turned my email automation tool into a full-fledged email platform Around 10 months ago, I published a tool I made ( https://ift.tt/1WM7wmq ). I was scouring the market for an affordable and easy-to-use email automation tool, to no avail. The solution? I decided to just build it myself. Since then, I've added the ability to send transactional and broadcast emails, threw out the subscription pricing and turned it into a usage-based model, etc. In short, turned it into a full-fledged email platform designed for SaaS. With this post, I would like to share my learnings, findings... Ask any question and I'll answer it to the best of my ability. Thanks to the feedback of the HN community, I was able to turn this into something that I am still proud of every single day. A sincere thank you from my side. https://ift.tt/4RgVnmf June 9, 2023 at 02:20PM

Show HN: A cross-platform command-line tool to play music Can add music from files, YouTube/YT Music links, or Spotify links. Fine-tuned control over looping, shuffling, etc. Built-in audio visualization, stats (yearly and total). Discord integration (status) and Mac integration (works with Siri, touch bar, headphones, any sort of media control on Macs). Honestly think this is a pretty good alternative to tools like ncmpcpp, but lmk what y'all think! https://ift.tt/tCAfFN2 June 9, 2023 at 11:01AM

Show HN: Visibly – More Collaborative and Efficient Code Reviews on GitHub https://ift.tt/u7Y2ka6

Show HN: Visibly – More Collaborative and Efficient Code Reviews on GitHub Hey HN! I’m Nick, the founder of Visibly ( https://visibly.dev ). Visibly is a GitHub App and Chrome extension that makes code review more efficient, collaborative, and visible by enabling you to: - See review comment thread statuses so that you can quickly address each thread and focus your attention on the ones that actually require it - Indicate whether feedback is blocking or non-blocking so only crucial feedback blocks PR merge - Ensure all blocking review threads are addressed before merge via a status check - Track total active review time per reviewer so that you can understand the effort and review time going into each PR - See reviewer presence so that you can see if someone is already reviewing and avoid unnecessary pings. In addition to these workflow improvements, Visibly provides a personalized metrics dashboard so you can understand your real-time performance and better advocate for yourself and advance your career. You can see a demo and a breakdown of all of the current features at https://visibly.dev . I created Visibly after seeing the same pain points across Microsoft, Snap, Headspace, and Brex: - Code review was frequently undervalued and invisible. Developers recognized this and prioritized code production instead, which resulted in knowledge silos, poor code quality, and a culture of rubber stamp reviews. - Engineering performance review was broken. From the manager’s perspective, it was difficult to identify top performers and to provide timely, actionable feedback. From the IC’s perspective, feedback was infrequent and subjective around many aspects of the job. The process was also time-consuming and required everyone to sift through 3-6 months of work to quantify “impact and scope”. Visibly solves these issues by using objective measures to make code review more visible and efficient. Visibly values privacy and security above all else; it does not require source code access and requests the fewest possible permissions to provide these experiences. Visibly is also differentiated in its belief that individuals should know how they’re doing and have personalized metrics so that they can advance in their careers. If you use GitHub, you can try Visibly today for free by heading to https://ift.tt/N6ArPMy . Visibly is currently free, but we plan to introduce paid features and pricing plans soon. Our pricing is still under development, but based on existing customer feedback, we expect to price at $20/seat/month. For those that sign up over the next week, we plan to provide 50% off for the first year once our pricing plans launch. We look forward to your thoughts and feedback! https://visibly.dev June 9, 2023 at 12:06AM

Show HN: A non-recursive C Quadtree https://ift.tt/XfpwJgt

Show HN: A non-recursive C Quadtree Wazzup Beijing, You might have seen a HSHG written by me the other day (supahero1/hshg, post: https://ift.tt/bzg2EXl ), which I also shared here. Well, I've quickly come to the realization that while grids are really nice, they really suck at handling objects of varying sizes. The HSHG could handle 500k objects of very similar sizes at 60FPS, and this Quadtree handles 100k objects of all sizes (can vastly vary or be similar, doesn't matter) in a similar amount of time. Also, while HSHG was really close to being O(n), this Quadtree is much worse, of course resembling O(log n). The way how I achieve lack of recursivity is doing a modified depth-first search. A modified one, because I first add all child nodes to the stack before descending to the first one of them, so the maximum stack length is depth * 3 + 1 , and I assume no madman will want to go over the depth of 20 (by default, can be changed). For some reason, this time around, running this on my laptop actually results in worse performance than I get on my PC, whereas the situation was the reverse with the HSHG haha. No clue why. Some lack of dirty optimizations I suppose. This time, no JavaScript port. I just wanted to whip out this Quadtree real quick (took me a week in total, from scratch) to use in some other project of mine. However, I do hope some people can make use of it, or maybe learn how non-recursive Quadtrees work, idk. On the other hand, this time I included a nice OpenGL + GLFW display showing exactly what's happening and how the Quadtree divides and merges its nodes. You can move around with your mouse (by dragging), and you can click LMB to warp to the fastest object in your view, which then you can deactivate (stop following the entity) by pressing RMB. Hope you enjoy! ~don_shadaman https://ift.tt/XvhJ34O June 8, 2023 at 05:04PM
