Show HN: OpenObserve – Elasticsearch/Datadog alternative https://ift.tt/qprU5R6

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/z2wCcj9 . We are in early days and would love to get feedback and suggestions. https://ift.tt/cN1AoMI June 11, 2023 at 04:05PM

Show HN: Reddit Archiving Tool https://ift.tt/nXSLgJY

Show HN: Reddit Archiving Tool Inspired by the ongoing call-to-action by the Internet Archive team over at /r/DataHoarder [1], I've decided I want to try to preserve all cybersecurity related subreddits. [2] For people that don't know what's going on: There's a likelihood that the try to monetize the Reddit API will lead to a lot of moderators quitting the platform, and it could be that a lot of subreddits are going to be set on private and/or their threads are going to be deleted. At least that's kind of the fear from the ongoing moderator strike. In my case I learned a LOT from reddits' discussions about malware, exploits and how they work, and without those I certainly wouldn't be where I am today ... so I'm trying to preserve them. As the Archive Warrior only scrapes the HTML directly to the Web Archive, I'm trying to preserve the data itself directly as JSON files; with intent to store it later on IPFS (having been inspired a couple days ago by the-eye-team's effort to archive RARBG on IPFS). I just wanted to let people know here about the tool, and in case you want to archive your favorite subreddits, feel free to modify it. There are some limitations though, because listings (new/hot/top/search) are all limited to 1000 entries, which means that the discovery of old threads is quite limited. Keyword search increases the discovery of old threads. In my case I'm searching for a lot of keywords (like CVE, RCE, vulnerability etc) in order to discover more threads. Would love to hear feedback, currently it's just a prototypical quick n' dirty tool because the threat of my favorite subreddits going dark is quite immediate. I tried to reduce as much noise from the schema as possible, and the tool is only archiving the subreddit threads and comments, with the idea to be able to scrape the websites/blog articles at a later point in time.

Show HN: Yo.link – Subdomain based URL shortener https://ift.tt/XWRO6iM

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/9art0fh https://ift.tt/idWLhHF --> https://ift.tt/a1NJrpd... 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/ClnsH9y

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/Qy5ZVJe June 10, 2023 at 02:44PM
