Show HN: Colorfle – A daily color mixing game inspired by Wordle 16 by tothemoon | 4 comments on Hacker News. Hi HN, I was inspired by Wordle to make Colorfle, a different take on the genre where the goal is to mix colors together to match the target color within six tries. There were some interesting problems to tackle in making this game, one of them being the difference between mixing digital colors and real-life behavior (in RGB, blue + yellow = grey!). I hope you enjoy it -- any feedback would be much appreciated!

Show HN: Radiopaper – Troll-resistant public conversations 33 by evnp | 6 comments on Hacker News. Hi HN! We're a bootstrapped team of 4 and have been building Radiopaper for around 16 months alongside other full-time, part-time, and consulting jobs. I wanted to highlight a couple of the unique characteristics of Radiopaper that may not be immediately apparent when browsing https://ift.tt/mTLzuUn * It's possible to interact with Radiopaper entirely by email, and never log-in interactively. The notification emails contain context that explains that if you reply to the email, your message will be published on https://radiopaper.com * The key mechanism that makes Radiopaper different from other social networks, and more resistant to trolling and abuse, is that messages are not published until the counterparty replies or accepts your comment. You can read more about this in our manifesto at https://ift.tt/tnxrevg The technical stack is a Vue/TypeScript app talking to an API back...

Show HN: WeakVim, My attempt at a modular, transparent starter kit for Neovim 2 by weakfish | 0 comments on Hacker News. Hi all, I _love_ Neovim. However, I think many parts of it could be easier to configure or understand, especially when it comes to LSPs. There's a ton of plugins that fill the gap, but some of them are sparse in documentation. There's also distributions like LunarVim that attempt to add a Doom Emacs-like layer above. My approach is a bit different, simply giving an opinionated, modular, and documented configuration that an interested user can easily modify to their needs. It makes use of the most helpful plugins I've encountered to create the best experience I could muster while retaining an air of simplicity. I hope this is helpful to someone out there!

Show HN: Lists.sh – A Microblog for Lists 26 by qudat | 5 comments on Hacker News. Greetings, creator here! I've been working on a new blogging platform specifically for lists on and off for a few months now and I'm excited to officially announce its launch. After seeing https://charm.sh a few months ago, I've been enamored by the idea of SSH apps. I decided that a blogging platform focused on developers could be the perfect use case for an SSH app. Also, I love writing lists. I think restricting writing to a set of lists can really help improve clarity in thought. The goal of this blogging platform is to make it simple to use the tools you love to write and publish lists. There is no installation, signup is as easy as SSH'ing into our CMS, and publishing content is as easy as copying files to our server. Check it out and let me know what you think! source: https://ift.tt/HJ23gNf

Show HN: Linen – Make your Slack community Google-searchable 13 by cheeseblubber | 3 comments on Hacker News. Hi HN! Kam here. I’m the founder of Linen.dev https://linen.dev , a website that makes your public Slack community Google searchable. Linen will sync your Slack threads and make it SEO friendly so your community can find Slack content that was previously hidden. Previously I worked on a popular open source project which had a sizable Slack community. Slack was great for engaging with community members and with early sales. However as community scales Slack becomes this black hole where context becomes lost. Most public communities can’t afford to pay for several hundred/thousand members so they are limited to 10,000 free messages. You run into the problem of people asking repeat questions and not searching in Slack. It also doesn’t help that the Slack UX encourages posting and not searching. We experimented with Github discussions and Discourse but didn’t want another channe...

Show HN: M3O – Universal Public API Interface 2 by asim | 0 comments on Hacker News. Hey all, I'm Asim Aslam, the founder of M3O, a curated catalog of APIs that provides simple abstractions for the most common API use cases. The idea is to create a single place to explore, discover and consume public APIs as higher level building blocks. Most of the time I don’t use all the features of an API and I assume most devs don't either, so picking and choosing the common patterns, abstracting it away and surfacing a new building block is useful. For example, Twilio has a lot of APIs but I only care about SMS. Even then I just want a quick way to send it. So stripping it all away results in something that's one endpoint and 3 fields (from, to and message). Another example is something like email. There are services like sendgrid that provide a really feature rich experience for email but I’m just looking for something simple that will let me send plain text or html. There are a n...

Show HN: I'm making a dynamic language in Rust 2 by harpiaharpyja | 1 comments on Hacker News. https://ift.tt/lfAdGk3 An implementation of a dynamic programming language in Rust. Includes: Parser/Compiler, REPL, Virtual Machine, Bytecode Disassembler This started out as a learning project to teach myself Rust. It has grown into a decently substantial piece of software and I've learned quite a bit in the process! Some neat things: + A garbage collector that can store dynamically sized types without any double-indirection (i.e. I have my own Box implementation with manual alloc/dealloc) + The smart pointer used to reference GCed data is a thin pointer. The ptr metadata needed for DSTs is stored in the GC allocation itself, so that the GC smart pointer is just a single usize wide. This allows me to keep the core value enum Variant down to 16 bytes (8 bytes for data, the enum discriminant, and some padding). + The GC also supports weak references! + Statically dispatched type ob...

I'm going to see if there's anything I can do to keep the text-generation part available, but in the meantime, the pre-generated set should stay pretty stable. Not sure if there's much else I can do without burning a hole in my cloud bills — sorry for the troubles!

Show HN: A better Reddit search engine to find Menswear recommendations 5 by adrielyong | 3 comments on Hacker News. Hey HN Community! We built this simple community search tool that basically allows people to search through thousands of past Reddit threads and tens of thousands of recommendations using tags. It mostly covers a few bigger subreddits like r/BIFL, r/MFA, r/AskMen, r/SkincareAddiction but along the way, I expanded it to include other smaller subreddits too. In addition to filtering by category, power users can also search by -Body Fit (big thigh, long torso) -Occupation (work in retail, teacher, doctor) -Age (18-24, 25-35), Size (height, weight) -Brand comparison (similar to: X) -Use (suitable for wedding, everyday wear) -Location (available in UK, use in Northeast US) -Mood/Style (minimalist, vintage, retro) Check it out.

Show HN: A programmer's approach to finding gifts 11 by cvanvlack | 4 comments on Hacker News. 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.

Show HN: I built an app to help with Windows container networking 2 by BasiliusCarver | 0 comments on Hacker News. 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.

We are coming out of stealth today and would like to invite the community to give us a try. https://ift.tt/G78ZkVd 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...

Show HN: Two-way Jira sync in a collaborative spreadsheet and Gantt 20 by electric_muse | 14 comments on Hacker News. Hello HN, Our startup nearly died 2 years ago. We kept losing customers to spreadsheets. And it made us see a problem right under our nose: everyone just wanted flexibility & speed from a spreadsheet. But they have to stay in sync with {Jira / Salesforce / insert SaaS app}. When we followed this thread, we discovered how broken the integration experience was for flexible products like Airtable, Smartsheet, Monday, and Google Sheets. Their big problem is that they transform external data into their own format. This makes setup harder, since you have to get the mapping just right. And often you can’t sync back. We took a different path when building Visor. We essentially made a data lake & ETL tool with a front-end. Visor integrates with your Jira instance, reads its schema, helps you import the right data, and lets you work in a flexible spreadsheet* that sync...

Show HN: JavaScript as a Database – Serverless Platform 7 by jpcapdevila | 8 comments on Hacker News. 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 javascr...

Devbook is an SDK that you add to your docs website and then every time a user visits your dev docs, we spin up a VM just for that user. The VM is ready in about 18-20 seconds. We haven't had enough time to work on optimization but from our early tests, we are fairly confident we can get this to about 1-2 seconds. In the VM you can run almost anything. Install packages, edit & save files, run binaries, services, etc. You as a documentation owner have full control over the VM. We give you full access to filesystem, shell, stdout, and stderr. You don't have to worry about any infrastructure management. It's just one line of code on your frontend. On the backend, the VM is a Firecracker microVM [1] with our custom simple orchestrator/scheduler built on top that just gets the job done. We chose Firecracker for 4 re...

Show HN: Factor.fyi – use SQL to visualize financial, crypto and econ datasets 4 by sdcoffey | 2 comments on Hacker News. Hey HN, I'm Steve, co-founder of Factor.fyi, a new data platform for querying and visualizing financial datasets using SQL. During the pandemic, I took much more of an active role in managing my portfolio. I wanted to be able to make informed decisions about the investments I was making, and explore financial data in new ways. Market and Econ data are some of the most talked-about and widely-available datasets out there, but I was frustrated by the lack of options to answer questions I had, like, "What would have happened if I had started dollar-cost averaging VTI back in 2013?"[1] Or, "How many days did BTC and ETH move in the same direction as the S&P500?"[2]. We built Factor to answer these questions. You can use Factor to query disparate datasets in ways that are impossible on any other platform. We currently have 20 datasets [3] t...

My team and I have been working hard to bring developers the next version of Supabase Realtime. The current version of Realtime [1] is a Change Data Capture (CDC) server for a PostgreSQL database that broadcasts changes via WebSockets to authorized subscribers. It’s written in Elixir/Phoenix. The server utilizes PostgreSQL’s logical replication functionality, which writes database changes to Write-Ahead Logging (WAL) segment files, and a replication slot, responsible for managing and retaining WAL files. Database changes are polled from WAL by the server using PostgreSQL’s replication function pg_logical_slot_get_changes and changes converted to JSON objects using the wal2json [2] extension by setting it as the output plugin. Security is enforced through two checks - each check ensures only authorized client subscribers ar...

I have a knack for curation and organization so I am putting my skills to, hopefully good use. This, at this point is intended for a global audience, stuff that make sense for most people. I got fed up with Google and other search engines results being filled with too many results that are not really useful and I hope Relevanto will eventually be a gateway for most of the stuffs I do on the web, leaving the search engines for more specific stuffs - to use them as an option rather than primary way.

Show HN: Programmatic – a REPL for creating labeled data 10 by jordn | 2 comments on Hacker News. Hey HN, I’m Jordan cofounder of Humanloop (YC S20) and I’m excited to show you Programmatic — an annotation tool for building large labeled datasets for NLP without manual annotation . Programmatic is like a REPL for data annotation. You: 1. Write simple rules/functions that can approximately label the data 2. Get near-instant feedback across your entire corpus 3. Iterate and improve your rules Finally, it uses a Bayesian label model [1] to convert these noisy annotations into a single, large, clean dataset, which you can then use for training machine learning models. You can programmatically label millions of datapoints in the time taken to hand-label hundreds. What we do differently from weak supervision packages like Snorkel/skweak[1] is to focus on UI to give near-instantaneous feedback. We love these packages but when we tried to iterate on labeling functions we had to write a ton ...

Show HN: Disable now useless “What's new” page in Firefox 3 by Tepix | 0 comments on Hacker News. Firefox 99 started serving a "What's New" page that is an ad for Pocket instead of listing what's new in the browser. Another disappointment. Here's how to disable the now useless "What's new page": 1. Go to about:config 2. Change the value of "browser.startup.homepage_override.mstone" to "ignore". Bingo! One less page with ads. Thanks for nothing, Mozilla.

Show HN: I made Million – It's a Virtual DOM made for the future 4 by aidenyb | 0 comments on Hacker News. Repo here: https://ift.tt/9M4fuAx My name is Aiden Bai and I'm really interested in HCI research, particularly within user interface (UI) and web development. At the time of writing this, I'm a student at Camas High School. In July 2021, Million.js began as an experiment with Virtual DOM because I was curious with how UI libraries worked. I was frustrated with the lack of a modern, fast, and modular Virtual DOM library for JavaScript. Virtual DOM had been around for almost a decade, yet many Virtual DOM libraries still struggle with render speed compared to newer methods of rendering. Today, Million.js is the first effort to bring Virtual DOM into the future after hundreds of hours of experimenting. Traditional Virtual DOM libraries have yet to leverage new technological paradigms in the new age of compiled Transitional UI Libraries. Million.js leverages the compile...

Show HN: Bloben – self hosted web CalDAV calendar client 2 by nibdo | 0 comments on Hacker News. Hello all, I have been working on a self hosted CalDAV calendar client Bloben https://ift.tt/DNUmnVZ This is mostly an alternative to other web clients like great AgenDAV with some additional features I wanted to use like email invites, alarms, webcalendars, etc. You can play with demo (limited to read access) here: https://ift.tt/bMsH3Bc In the end it should provide separate clients also for CalDAV tasks and notes. One thing I would maybe like to discuss more is adding encryption, which is obviously quite problematic when using standards like CalDAV. Initially I just added non-compatible fully encrypted calendars, but realised this might not be useful for many people using different clients. Something halfway is adding an option to protect only some, say sensitive, events by encrypting fields like title, description or location. That way events will still be displayed via standard mobil...

Show HN: Flight Penguin – Like Hipmunk, but a browser extension 7 by goldfish | 0 comments on Hacker News. Hi HN! I'm Adam Goldstein, co-founder and CEO of Hipmunk (S10). Today we're launching Flight Penguin ( https://ift.tt/iO6XqkJ ) in public beta as a browser extension for Chrome and Chromium browsers. Hipmunk was a travel metasearch site that sorted flights by "agony" and showed them in a Gantt chart view. I've missed using Hipmunk ever since SAP shut it down. So I decided to seed-fund a successor along with my Hipmunk co-founder (and Reddit CEO) Steve Huffman. More recently I brought on Max Morlocke (hn: maxmorlocke) as cofounder. With Flight Penguin, you get a simple, time-based way to search for flights, and it pulls in results from multiple sites. By default Flight Penguin sorts by "pain," so you see the least painful options before the multiple-layover monstrosities Kayak loves to show first. As some of you know, some airlines are now demandi...
