Show HN: Zsync, a Reddit Alternative with the Goal to Reward Quality Comments
I built this last year but never posted it anywhere, but now with Reddit hiatus it seems like the right time to give it a shot.<p>The main goal of zsync is to foster high quality content and discussion. That's it. If it can't accomplish that, then to me it is a failure. I watched Reddit go from having high quality discussion in 2008-9 to devolving into the PC meme dumpster it is today [1]. HN still has the highest discussion quality of any "forum" I know of, but (1) it can sometimes randomly be very hostile/toxic to new tech, the most glaring example being crypto. (2) HN is basically a single subreddit mostly geared towards tech and startups. It'd be nice to have an equivalent of "subreddits"<p>Zsync's version of subreddits are tags. You can tag your posts. Instead of viewing a subreddit for, let's say neuroscience, you view the tag for neuroscience. This eliminates the need to submit the same post multiple times to many different subreddits.<p>The core challenge is incentivizing/rewarding high quality content (I don't believe in censorship). Users can have custom avatars and links to their personal website and Twitter next to their username, which I believe provides a little more incentive to write a more thoughtful comment vs. your post merely showing up next to an anonymous handle with some autogenerated alien avatar (which you're free to still do if you prefer).<p>Anyone who connects an ethereum wallet to their account will also have a (non-invasive) "Tip" option at the bottom of their comment, allowing anyone to directly tip commenters cryptocurrency (no middleman taking a cut here), offering a financial incentive. I was thinking of some other ideas to use crypto to reward quality, but I wouldn't want to implement anything that could be gamed or exploited ultimately defeating its purpose. Open to ideas though.<p>In the future, we could use ML to offer options to sort comments in more useful ways, such as by sorting by "most insightful". We could determine based on your upvote history the type of content you'd be most likely to enjoy. Anyways I admittedly didn't implement this ML stuff yet, those are just ideas for future improvement.<p>Anyways would love to hear your thoughts. What do you think of this idea, and what would it take to accomplish its mission? Regardless of whether my little project amounts to anything or not, I hope something like this will be made to exist. And thank you HN for not deteriorating in quality even remotely to the extent that Reddit has. It was really sad watching Reddit devolve into what it is today (way before all this recent stuff). We can do better, and now is a better time than ever to shake up the status quo and start envisioning what better platforms for online communities can look like.<p>[1] <a href="https://jsavage.xyz/2022/03/13/the-downfall-of-reddit-why-reddit-sucks-and-how-to-fix-it/" rel="nofollow noreferrer">https://jsavage.xyz/2022/03/13/the-downfall-of-reddit-why-re...</a>

Show HN: Non.io, a Reddit-like platform Ive been working on for the last 4 years
Heya HN, I've been working on a reddit-like platform as my primary side project for the last few years. Doing a (very) soft launch today, mainly because I want to use it to encourage discussion of alternatives.<p>How non.io works:<p>1. Free to browse, paid to interact.<p>2. Minimum subscription is $2 (though you can choose more). I take $1 to run the servers, everything left gets split evenly between everything you upvote that month.<p>It's a simple model, but I hope it's a better one than the freemium model we've been relying on for the last few years. Fundamentally I feel like any ad-supported network doesn't have alignment between the needs of the users and the needs of the platform, which is what drove me to make this.<p>Because this is a soft launch, if you do subscribe I'd encourage you <i>not</i> to pay for the time being. I'm still testing the distribution algorithm for returning funds - you won't get overcharged or anything, but I just want to guarantee your funds are properly distributed at the end of the month. I've opened up free accounts to post and interact in the meantime. If you want to try a test account, use this login:<p>login: hackernews pw: helloworld<p>Edit: Loginless browsing here: <a href="https://non.io/#all" rel="nofollow noreferrer">https://non.io/#all</a><p>If you want to browse the code or the api:<p><a href="https://api.non.io" rel="nofollow noreferrer">https://api.non.io</a><p><a href="https://github.com/jjcm/nonio">https://github.com/jjcm/nonio</a>
Show HN: Java REST without annotations, DI nor reactive streams
grumpyrest is a Java REST server framework that does not use annotations, automatic dependency injection or reactive streams, and minimizes the use of reflection. I created this because I got fed up with annotation-mad frameworks that you cannot easily understand, step into or reason about. grumpyrest uses the type system to guide JSON mapping and validation, and (possibly virtual) threads for parallelism. It's for grumpy people who don't like what REST server programming in Java has become.<p>I made this because I intend to use it in one of my own projects, but at the same time I want to make it available to others to (hopefully) get some good ideas on how to extend it.

Show HN: OpenObserve – Elasticsearch/Datadog alternative
Hello folks,<p>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.<p>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.<p>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.<p>Here is a blog on why we built OpenObserve - <a href="https://openobserve.ai/blog/launching-openobserve" rel="nofollow noreferrer">https://openobserve.ai/blog/launching-openobserve</a>.<p>We are in early days and would love to get feedback and suggestions.

Show HN: Bloop – Answer questions about your code with an LLM agent
Hi HN! We launched bloop 10 weeks ago (<a href="https://news.ycombinator.com/item?id=35236275" rel="nofollow">https://news.ycombinator.com/item?id=35236275</a>) and received a huge amount of feedback (both positive + constructive). We've undertaken a rewrite of the core search framework, which now acts as an LLM agent, significantly improving the number of queries that can be successfully answered.<p>There's a bunch of hype surrounding LLM agents, but we're positive this is one of the first implementations of an agent that can deliver immediate value for engineers working on existing projects, especially larger ones. We'll do a full write up of how the agent works and the tools it can use soon, but we wanted to share our progress, now that we've got a stable release.<p>bloop is a developer assistant that uses GPT-4 to answer questions about your codebase. The agent searches both your local and remote repositories with natural language, regex and filtered queries.<p>Some of the ways engineers use bloop to improve their efficiency when working on large codebases:<p>- Summarise how large files work and how multiple files work together<p>- Understand how to use open source libraries when documentation is lacking<p>- Identify the origin of errors<p>- Ask questions about English-language codebases in other languages<p>- Reduce code duplication by checking for existing functionality<p>- Write new code, taking into account existing codebase context (eg: "write a dockerfile for this project")<p>bloop runs as a free desktop app on Mac, Windows and Linux: <a href="https://github.com/bloopAI/bloop/releases/latest">https://github.com/bloopAI/bloop/releases/latest</a>. On desktop, your code is indexed with a MiniLM embedding model and stored locally, meaning at index time your codebase stays private. 'Private' here means that no code is shared with us or OpenAI at index time, and when a search is made only relevant code snippets are shared to generate the response. (This is more or less the same data usage as Copilot).<p>We also have a paid cloud offering for teams ($45 per user per month). Members of the same organisation can search a shared index hosted by us and will get access to enterprise only features down the line (currently there's no feature gap between desktop and cloud).

Show HN: Arroyo – Write SQL on streaming data
Hey HN,<p>Arroyo is a modern, open-source stream processing engine, that lets anyone write complex queries on event streams just by writing SQL—windowing, aggregating, and joining events with sub-second latency.<p>Today data processing typically happens in batch data warehouses like BigQuery and Snowflake despite the fact that most of the data is coming in as streams. Data teams have to build complex orchestration systems to handle late-arriving data and job failures while trying to minimize latency. Stream processing offers an alternative approach, where the query is compiled into a streaming program that constantly updates as new data comes in, providing low-latency results as soon as the data is available.<p>I started the Arroyo project after spending the past five years building real-time platforms at Lyft and Splunk. I saw first hand how hard it is for users to build correct, reliable pipelines on top of existing systems like Flink and Spark Streaming, and how hard those pipelines are to operate for infra teams. I saw the need for a new system that would be easy enough for any data team to adopt, built on modern foundations and with the lessons of the past decade of research and industry development.<p>Arroyo works by taking SQL queries and compiling them into an optimized streaming dataflow program, a distributed DAG of computation with nodes that read from sources (like Kafka), perform stateful computations, and eventually write results to sinks. That state is consistently snapshotted using a variation of the Chandy-Lamport checkpointing algorithm for fault-tolerance and to enable fast rescaling and updates of the pipelines. The entire system is easy to self-host on Kubernetes and Nomad.<p>See it in action here: <a href="https://www.youtube.com/watch?v=X1Nv0gQy9TA">https://www.youtube.com/watch?v=X1Nv0gQy9TA</a> or follow the getting started guide (<a href="https://doc.arroyo.dev/getting-started">https://doc.arroyo.dev/getting-started</a>) to run it locally.
Show HN: I built an AI language teacher to get you speaking
Hello Hacker News,<p>When learning foreign languages, I made the most progress by speaking them throughout the day, every day. So I made a site where you can *speak* to an AI language teacher to practice both listening and speaking.<p># The product<p>*What I have now:*<p>* Multilingual speech recognition: You can ask a question in English and get an answer in your target language.
* Feedback on your grammar.
* Suggestions: See examples of what to say next to keep the conversation flowing.
* Speed: Choose a lower speed for beginners or a faster one for advanced levels.
* Translations: Click to see a translation into English (or another language).
* Role-playing: Practice real-life situations.
* Available to learn American English, British English, Australian English, French, Spanish from Spain, Spanish from Mexico, Brazilian Portuguese, European Portuguese, Russian, and more.<p>*What I'd like to add:*<p>* More Situations/Characters/Customizations: A "Creator mode".
* Feedback on your pronunciation.
* Text-based responses (Type or click – would feel like a "Create Your Own Adventure" book!)
* A dictionary.
* Phonetics: Zoom in and repeat a sound to help you hear phonemes and words more clearly.
* …and so much more!…<p># The startup<p>Been working on this for 6-7 months now.<p>I love this project and got lots of laudatory comments about it, but still find it hard to make it take off. 31% of people come back to it, traffic is growing through word of mouth with language teachers in schools or Telegram or private intranets sharing it with others. So that's nice. But nice words alone don't pay the bills.<p>My goal is to achieve enough growth to cover costs, which would then allow me to focus 100% on the product (currently it's more like 50% of my time). But I'm not there yet.<p>A challenge I see is that most places forbid self-promotion. So I'm just not sure how on Earth I'm supposed to have a product take off. I could pay for ads, but I use AdBlock everywhere so this feels out of character. I'm a big fan of Pieter Levels (@levelsio on Twitter) because he's doing things solo, so I'm trying to emulate the same kind of success. But it seems that something is missing.<p>What features would you find most useful? How can I better market this without resorting to ads?<p>Thanks for reading! If you've got thoughts or ideas, I would love to hear them.<p>Cheers,
Fabien
