Show HN: A programmer's approach to finding gifts https://bit.ly/3v5XcHo

Show HN: A programmer's approach to finding gifts Hey Folks, I’ve been really annoyed with the search part of finding gifts. It’s hard to use keyword search for something when it’s an “I’ll know it when I see it” kind of deal. So I thought, what if we scraped/indexed TONS of products and then just focused on removing the things we don’t want and then see what’s left to see if there’s anything cool? I built it in Flutter so it's both iOS and Android but it could be web too. I’ve only just started the scraping/tagging of products and if anyone has suggestions for bulk tagging images/content I would love to hear them. That’s the current bottleneck. Any feedback would be welcome! cvanvlack AT gmail DOT com if you want to discuss 1-on-1. https://bit.ly/3v7xQJn April 22, 2022 at 11:35AM

Show HN: I built an app to help with Windows container networking https://bit.ly/3L8MYvo

Show HN: I built an app to help with Windows container networking I've been playing with cross platform windows/linux Kubernetes clusters recently and have had endless problems with installer scripts misconfiguring networking by using the wrong NIC etc. I got frustrated with the tooling on windows to debug container networking so I built a tool that attempts to stitch together the HNS (Host Network Service) & HCS (Host Compute Service) resources into a tree that shows the relationship between configs. You can also search over it to find the networking impacting your containers or launch the windows built in packet capture tool to create a network trace you can open in Wireshark for analysis. I'm not a desktop app developer so it's pretty rough around the edges and I've only really tested on Windows 11 and Server 2019. https://bit.ly/3v3oA8P April 22, 2022 at 07:38AM

Details: - I'm the sole developer and founder - I applied to YC S22 batch on the last day - Currently facing a big KYC compliance wall (code and protocols) - My priority right now is obtaining funds to cover minimal operational cost's. Need to pay for broker partnership costs too. - I have essentially no funds to cover cost's right now. - Currently applying for dev positions on several companies. - Developed the beta version on 3.5 months full-time. Thank you https://bit.ly/3K9IpzI April 22, 2022 at 02:31AM

Show HN: Dassana. JSON-native,schema-less logging solution built atop ClickHouse Hello HN, I’m Gaurav. Founder & CEO of Dassana. We are coming out of stealth today and would like to invite the community to give us a try. https://bit.ly/3k020rv First, a bit of a backstory. I grew up with grep to search log files. The kind of person whose grep was aliased to grep -i . Then came along Splunk. It was a game-changer. For every single start-up I started (there are a few) I used Splunk and quite often we will run out of our ingestion quota. SumoLogic wasn’t cheaper either so we looked into DataDog. It was good until we started running issues with aggregate queries (facets etc), rehydration takes forever and the overall query experience is not fun (it wasn’t fun with Splunk and SumoLogic either). All these experiences over the last two decades led me to wish for a simple solution where I can just throw a bunch of JSON/CSV data and query it with simple SQL. These days most logs are structured to begin with and the complexity of parsing logs to extract fields etc has moved to log shippers such as fluentd, logstash etc. Enter HackerNews and ClickHouse. I first learned about ClickHouse from HackerNews and was completely floored by its performance. Given its performance and storage savings due to columnar storage, it was an obvious choice to build a logging solution on top of it. As we started doing POC with it, it was obvious that it is a perfect solution for us if we could solve the problem of schema management. Over the last six months or so, that’s what we have working on. We designed a storage scheme that flattens the JSON objects and exposes an SQL interface that takes a SQL and converts it to our schemaless table query. Being JSON native, we allow querying specific JSON objects in arrays. This is something that is not possible with many logging vendors and if you use something like Athena good luck figuring out the query- it is possible but quite complicated. Here is sample query - select count(distinct eventName) from aws_cloudtrail where awsRegion=us-east-1 Also, there are no indices, fields, facets etc in Dassana. You just send JSON/CSV logs and you query them with 0 latency. And yes, we do support distributed joins among different data sources (we call them apps). And like any other distributed system, it has limitations but it generally works great for almost all log-related use cases. One amazing side effect of what we built is that we can offer a unique pricing model that is a perfect match for logging data. Generally speaking, log queries tend to be specific. There is always some sort of a predicate- a user name, hostname, an IP address. But these queries run over large volumes of data. As such, these queries run insanely fast on our system and we are able to charge separately for queries and reduce the cost of ingestion dramatically. In general, we expect our solution to be about 10x cheaper (and 10x faster) than other logging systems. When not to use Dassana? Not suitable for unstructured data. We don’t offer full-text-search (FTS) yet. We are more like a database for logs than a lucence index for text files. With more and more people starting to use structured logs, this problem with either go away on its own but as I said, we do plan to offer FTS in the future. Note that you can already use log shippers such as fluent, vector,logstash etc to give structure to logs. What’s next? 1. Grafana plugin. Here is a sneak preview- https://bit.ly/3L3LNxb 2. Alerting/Slack notifications. You will be able to save queries and get Slack notifications when results match. 3. JDBC driver. 4. TBD. You tell us what to build. Email me and I will personally follow up with you: gk 8 dassana dot input/output I will be online all day today happy to answer any question. Feel free to reach out by email too.

Show HN: JavaScript as a Database – Serverless Platform https://bit.ly/3KWSYqZ

Show HN: JavaScript as a Database – Serverless Platform Hi HN! I’d like to share with you my project: JSDB. Two months ago I had this thought while reviewing a PR on a web application. What if I didn’t have to write code to communicate with my backend or database? It would be fun to just use arrays and objects like you normally do in javascript and have things magically save. That weekend I hacked together something that used proxies and classes to ‘magically’ send data to your backend when you assign or access properties in an object or array. Using the same API you already know. This means you can save data like this: items[x] = {a:2,b:false} and read data like this: console.log(await items[x].a) or console.log(await items.find(o => o.a === 2)) While sharing it with some devs I started to get comments like this? “Wow that’s super simple. Is it secure?” So I started building a platform around this idea. A platform that allows javascript developers to write full stack applications, with the least overhead possible and just writing javascript. Security Rules are JS functions, files are simply assigned to an object property, triggers are JS functions etc. Everything is javascript! Check the docs: https://bit.ly/3uVuusD Why? Because there are developers that can write code using arrays and objects but are not confident with backend code. I would like to lower that barrier and empower every developer that knows JS to be full stack with the least effort possible. For experienced developers, less boilerplate means less bugs and faster product cycles. I like to think that JSDB is positively influenced by this post from Rich Harris: https://bit.ly/3uXZCrK Aren’t there other platforms that solve this problem? Yes, there’s some great efforts. Supabase recently had a killer launch week and I have tons of respect for what they’ve accomplished. JSDB targets the javascript lovers, the devs that rather just write javascript and would like to avoid sql if possible. By design it will only work on javascript codebases. Is this production ready? No! It’s still an MVP, designed to show the idea and where I’m going. That's also why there are limited spots for the hosted preview alpha (you can always self host). If this sounds interesting check this demo: https://youtu.be/xs30II7HNBQ Docs: https://bit.ly/3uVuusD Website: https://bit.ly/3jR2NLd Github: https://bit.ly/393QJ7p Looking forward to getting candid feedback :) https://bit.ly/3jR2NLd April 19, 2022 at 02:17PM
