Show HN: Colorfle – A daily color mixing game inspired by Wordle 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! https://colorfle.com/ April 29, 2022 at 08:20PM

Show HN: Radiopaper – Troll-resistant public conversations https://ift.tt/Db1XRVt

Show HN: Radiopaper – Troll-resistant public conversations 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 backend written in Go, running on Cloud Run, and using Firestore for persistence, Firebase Auth for authentication. Email processing is handled through the Gmail API hooked up to a Cloud Pubsub notification which triggers another Cloud Run service. Outbound emails go through SendGrid. The whole stack "scales-to-zero", and on days that we have a few hundred active users, we're still under the free limits of Firebase Hosting, Cloud Run & Firestore, so this has allowed us to operate for a long time without funding or revenue. Our overall burn rate is around $40/month, mostly from the smattering of other SaaS offerings we use: Sentry, Mixpanel, Github & SendGrid. Dave & I discuss our tech stack in a little more detail in this conversation: https://ift.tt/2DjrLkq The team (myself, daave, davidschaengold, youngnh) will be around to answer any questions! https://ift.tt/mTLzuUn April 30, 2022 at 02:48AM

Show HN: WeakVim, My attempt at a modular, transparent starter kit for Neovim 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! https://ift.tt/ykR8OzY April 29, 2022 at 05:33AM

Show HN: Loodio – A Bathroom Privacy Device https://ift.tt/gsN3FJo

Show HN: Loodio – A Bathroom Privacy Device Hi HN! A few years ago our company moved to a new office. That office has a insufferable bathroom in terms of privacy. You could hear a needle fall on the floor inside of it which made it very uncomfortable to use the bathroom. Many people ran the tap water or fake coughed to cover their “noises”, especially doing “no 2”. I got sick of not being able to be comfortable in the bathroom and hearing everyone’s toilet business so I decided to make a music player using a Raspberry Pi and soldered on a motion detector that started a white noise and music whenever you entered the bathroom to hide these sounds. A lot of people said they wanted one so I thought hey I should try to make this into a product. A lot of time and money was wasted hiring consultants until I 13 months ago said “enough of wasting money, I’ll just build it myself”. Today I launched a kickstarter and am selling 50 units. Link: https://ift.tt/YGoCH6E I know people in US have loud fans and such to cover for this, and a lot of people just play music on their phones but the problem with that is: when you manually play music in there you indicate you are going to do something embarrassing! How else are you solving this problem? I tried all existing solutions like the Sound Princess from Japan and other chinese crap on Amazon/Ali but they were not up to the task. I think there could be a market for Loodio. What do you think? April 27, 2022 at 09:02PM

Show HN: Linen – Make your Slack community Google-searchable https://ift.tt/HcqMZTY

Show HN: Linen – Make your Slack community Google-searchable 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 channel to maintain and split the community on. With Linen I wanted to build a tool that is very low maintenance without changing my current workflow. By making it search engine friendly and putting it on a website the community members can find answers to repeat questions before ever getting into your Slack channel. Linen is the first result that comes up on Google if you search for “seeing a weird issue with flyte” https://ift.tt/q3dNS8l... or “replace beast http with proxygen” https://ift.tt/9hdYeu6... . As a side effect of syncing conversation to a website you end up with a very long tail of unique and relevant content for your community. Linen is free to use and get setup but I offer a paid version (I am still figuring out the pricing model for it) where you can get the content redirected to your own subdomain where your domain gets all the SEO benefits. Linen is built with Nextjs, Node, Typescript, React, Prisma for the ORM and using AWS aurora for the Postgres db. I chose Nextjs for the server side rendering capabilities and wanted to share types between client side with Typescript. I’ve also enjoyed working with Prisma as the ORM since you don’t have to write a lot of boilerplate with other ORMs. I've also been pretty happy with Vercel and Nextjs especially with the server side rendering and client side caching it provides. Here are a few communities on Linen right now: https://ift.tt/i5UDWm8 https://ift.tt/5TNdAIH https://ift.tt/vMtImUT https://ift.tt/gp0lomw https://ift.tt/gFdNQAV https://ift.tt/UmWlTXw The product is very simple right now but I want to add features like related questions detection with semantic similarity, integrating with Github to notify the thread when it is finished, auto thread detection for conversations that aren’t in thread form. You can sign up for free today at https://www.linen.dev . I am doing manual onboarding at the moment to get better feedback and to manually walkthrough some of the less polished parts of the boarding flow. p.s. I’m actively working on supporting Discord on Linen so would love to hear from anyone that is interested April 26, 2022 at 09:10PM

Show HN: M3O – Universal Public API Interface https://ift.tt/hgDRI6H

Show HN: M3O – Universal Public API Interface 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 number of API marketplaces out there, but we’re doing something different—our goal is to improve productivity. For example, RapidAPI has thousands of APIs, but there’s a lot of duplication. It’s overwhelming for developers. Choice is the enemy of productivity. AWS, on the other hand, focused on a curated catalog of services where each focuses on a specific problem. We feel the same: from an API perspective you only need one of each building block. You only need one SMS, Email or Geocoding service. My obsession with this problem goes back to working as an SRE at Google in 2011, seeing how the internal platform and APIs were being used by teams. I then worked at a ride hailing startup called Hailo where we got to build something similar, and experience the velocity of development in shipping products on top of simple, easily discovered APIs. I spent the next few years bootstrapping an open source project called Micro, trying to get people to standardize their API development to reach this goal. Ultimately it took raising funding to take a real shot at it. After seeing the productivity Google unlocked and what Hailo could have done with their platform, it was clear it could and should be a product: a single way to consume APIs with one platform, one account and one framework. Our goal is to build an API catalog that can act as the building blocks for most use cases, and then double down on services that have a lot of demand so we can improve the features and reliability. In the wild, every API looks different, the docs are different, you have to figure out if there's client libraries or not. We unify all that, so everything looks and feels the same. All our docs are generated based on OpenAPI specs, and we code generate examples/client libraries for JS, Go, Dart and the CLI. It means you only ever need one client to access all these APIs. Unifying API development and consumption requires a lot of resources to do at scale, hence its only happening inside fast growing startups and large tech cos. There are a lot of barriers to entry. Getting started isn't easy. Our approach has been to first nail API development for ourselves and then focus on API consumption by end users— ultimately we want to let anyone offer APIs on our platform. That requires enough large scale distribution and inbound traffic to make an attractive proposition to developers. We've spent a year building the product with a lot of feedback on what worked and what didn't. We’ve signed up 8000 people, served 5M API requests and have 60+ APIs on the platform. On billing: we're still figuring it out and would like feedback. It started as a free product, then moved into per request pricing. Unfortunately that's hard to scale without a lot of volume and it felt like people were more used to subscriptions for SaaS products so that's the route we've gone. Anyway that's us, hope you like the idea and try it out: https://m3o.com . Cheers Asim https://m3o.com?show=hn April 25, 2022 at 03:39PM

Show HN: I'm making a dynamic language in Rust https://ift.tt/JIxRljO

Show HN: I'm making a dynamic language in Rust 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 object model using a newtype wrapper and Rust's declarative macros. Ok, what that means is that I have a MetaObject trait that I can use to easily add new data types and define the behavior for specific types. Similar idea to Python's PyTypeObject though very different in implementation. However, I don't resort to dynamic dispatch or trait objects despite working with dynamically type data. Instead, I have a newtype wrapper over the core value enum Variant that statically dispatches to each of the enum branches! And then a few macros that minimize the boilerplate required if I want to add a new branch to Variant or a new method to MetaObject (just a single line in each case). + Different string representations! This was inspired by the flexstr crate. Strings that are short enough to fit inside a Variant are "inlined" directly in the value. Longer strings are either GCed or interned in a thread-local string table. All identifiers are interned. + An efficient implementation of closures inspired by Lua's upvalues. The language is still pretty WIP. I'm planning to add an import system, a small standard library, and a few other things (Yes, the name might not be the best, being also used by a well-known ReST docs generator, I'll take suggestions. I do like the name though, both as a reference to the mythological creature and the cat :D) April 25, 2022 at 05:16AM

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.

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://ift.tt/drkhnex April 22, 2022 at 12:08PM

Show HN: Two-way Jira sync in a collaborative spreadsheet and Gantt https://ift.tt/A62vQqy

Show HN: Two-way Jira sync in a collaborative spreadsheet and Gantt 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 syncs both ways. There’s also an interactive Gantt & Timeline view. *Spreadsheet is a generous term for now. Formulas are still on the roadmap. As are many true “spreadsheet” features. But we’re working towards it. Our roadmap is public, here: https://ift.tt/gd821mE And for VueJS devs, we eked out more performance from Vue 2 by modifying the core, documented here: https://ift.tt/4KdYESi... For database geeks, you might enjoy learning about the realtime graph DB we built to power the product: https://ift.tt/ZWoVjHP I’ve seen so many great companies start out by launching on HN.

Show HN: Employees.fyi – Easily compare U.S. workforce demographic data Hi HN! We built Employees.fyi to make it easy to compare U.S. workforce demographic data across companies and against industry reference data. In the U.S., the Equal Employment Opportunity Commission (EEOC) requires the collection and submission of demographic workforce data. We collected and organized the publicly available federal data from the EEOC as well as publicly available EEO-1 submissions from individual companies. By doing so, we hope to make it easy to compare U.S. workforce demographic data across companies and against industry reference data. The URL contains your current selection. Just copy the URL and share it! Some examples: * A comparison of 2018 data for the "Professionals" job category across the Information industry, Facebook, and Netflix: https://ift.tt/ETluBLX... * A comparison of 2018 data for all job categories across the Finance and Insurance industry, BlackRock, and PayPal: https://ift.tt/jUz4JtS... * A comparison of 2018 data for the "Exec/Sr Officials & Managers" category across the Professional, Scientific, and Technical Services industry, Accenture, and Nvidia: https://ift.tt/LNswfK6... If there's a company with EEO-1 data that you would like to see, consider submitting a URL via this form: https://ift.tt/GUcoKCA Let us know what feedback you have for us!

Show HN: Fast,Compiled deep-learning based modules for inferencing on CPUs Hi HN,I am Anubhav from RamanLabs.We have been developing dedicated modules based on deep-learning for purposes like face-detection,object-detection,pose-estimation etc. We hope to make it easy for developers,hobbyists to integrate such functionalities into their existing app/pipeline at the cost of a few milliseconds.All our modules run end to end in super-realtime even on consumer-grade CPUs[0]. For now we provide only Python based API. We provide Demo for each of the modules to allow testing for your desired data distribution.We also have a blog[1] where we hope to add more technical details about the framework used to develop these modules. The framework used to develop these modules is completely written in Nim language.We wrap existing ops implementations from libraries like ONEDNN and write our own code where we cannot find one or existing implementation is not good enough,mainly for preprocessing and postprocessing code.Having full access to framework code and being written in a high level language allows us to port newer architectures and optimize them quickly. We would love to hear your feedback on our attempt. [0] Quad-core Cpu with AVX2 instructions. [1] < https://ramanlabs.in/static/blog/index.html > https://ift.tt/NutIY4B April 14, 2022 at 11:38PM

Show HN: Usage, Cut your AWS Bill by 50%+ in 5 Minutes https://ift.tt/Ny6tJYe

Show HN: Usage, Cut your AWS Bill by 50%+ in 5 Minutes Hi HN community, [Direct Link: www.usage.ai] I’m Kaveh, founder and CEO of Usage, and am excited to show you Usage, an app that helps you slash your AWS EC2 bill by 50% in ~5min by trading reservations. As of today, Usage is in General Availability and any AWS user can use it. It works by creating a limited-access IAM role (ReadOnly + Ability to Manage Reservations) into your AWS account(s). The AWS console interface has made it hard for companies to optimize their AWS spend. After years of working for different companies that use AWS, I still find it difficult to understand how much money I’m spending on AWS. I don’t know who owns what instances, how our commitments are saving us money (RIs, SPs, EDPs), and what instances can be sized down (or switched to spot). At Usage, we are building a web-based app that keeps you in charge of your AWS while minimizing your bill. No code change, no moving your AWS account or instances around, and no downtime. We’ve built: 1) Real-Time RI/SP Recommendations: See which instances are uncovered by your SPs and/or RIs and get them covered with a single button tap. Instant savings. 2) RI Sell Recommendations: RIs that are no longer utilized are highlighted and sold instantly. No more worrying about unutilized RIs and no more needing to forecast your compute needs. 3) Consolidated View: View your EC2 instances and RI/SPs across all your AWS accounts in a single space. No more switching between AWS accounts. 4) Teams and Audit Log: Add as many users as you’d like to your Usage dashboard, and see who approved which recommendations. We built Usage in ReactJS, Python, Java– and along the way we built our own internal accounting system to keep track of customer savings. We have plans to eventually release an open-source version of Usage. Our business model is 20% of the savings we find you. We only make money when we save you money. We bill monthly and have longer-term enterprise plans available. We take privacy extremely seriously. Your data is always protected both at-rest and in-transit. Additionally, Usage never collects or stores sensitive information. Usage only collects meta-data such as CPU utilization, launch time, instance configuration, region, etc. You can read our full privacy policy here: www.usage.ai/policy/ We are confident we can deliver a better AWS cost savings experience that is meaningfully better than other tools. If you use AWS, please give it a shot at www.usage.ai and let us know. Let me know what you think! Ask me anything! April 13, 2022 at 08:08PM

Show HN: Razer x Lambda Tensorbook https://ift.tt/qi5967n

Show HN: Razer x Lambda Tensorbook Hi all, long time lurker, first time poster. I want to share with you all something we've been working on for a while at Lambda: the Razer x Lambda Tensorbook: https://www.youtube.com/watch?v=wMh6Dhq7P_Q But before I tell you about it, I want to make this all about me, because I built this for me. See, while I'm genuinely interested in hearing from the community what you think as this is the culmination of a lot of effort from a lot of people across so many different fields (seriously, the number of folks across manufacturing, engineering, design, logistics, and marketing who have had to work together to launch this is nuts), I really just want to tie the larger motivations for Tensorbook as a product back to a personal narrative to explain why I'm so proud. So, flashback to 2018, and I'm a hardware engineer focusing on the compute system at Lyft's autonomous vehicle (AV) program, Level5 (L5). Here was a project that that would save lives, that would improve the human condition, that was all ready to go. I saw my role as coming in to product-ize, to take what was close to the finish line and get it over it. The disappointment was pretty brutal when I realized just how wrong I was. It's one thing to nod along when reading Knuth write "premature optimization is the root of all evil"; it's another to experience it firsthand. At Lyft L5 I thought I would be applying specialized inference accelerators (Habana, Groq, Graphcore, etc.) into the vehicle compute system. Instead, the only requirement that mattered org-wide was: "Don't do anything that slows down the perception team". Forget testing silicon with the potential to reduce power requirements by 10x, I was lucky to get a willing ear to hear my case for changing a flag in the TensorFlow runtime to perform inference at FP16 instead of FP32. Don't get me wrong, there were a multitude of other difficult technical challenges to solve outside of the deep learning ones that were gating, but I had underestimated just how not-ready the CNNs for object detection and classification were. Something I thought was a solved problem was very much not, and ultimately resulted in my team and others building a 5,000 watt monster of server (+ power distribution, + thermals, + chassis, etc etc) that took up an entire rear row of seating. I'm happy to talk about that experience in the comments because I have a lot of fond memories from my time there. Anyway, the takeaway I have from Lyft, and my first motivation here is that there is no such thing as over-provisioning or too much compute in a deep learning engineer's mind. Anything less than the most possible is a detriment to their workflow. I still truly believe AVs will save lives; so by extension, enabling deep learning engineers enables AVs enables improvement to the human condition. Transitive property, :thumbsup: So moving on, my following role in industry was characterized by working closely with the least technical people I have ever had the opportunity to work with in my life. And I mean opportunity genuinely, because doing so gave me so much perspective on the things that you and I here probably take for granted. (How do we know that Ctrl+Alt+T will open a terminal? Why does `touch` make a file? How do I quit vim?) So, the takeaway from that experience, and motivation #2 for me is that computers can be so unaccessible in surprising ways. I have a deep respect and appreciation for Linux, and I want others to see things the same way, so anything I can do to make easier the process of "self-serving" or "bootstrapping" to my level of understanding, is something worth doing to me. So, with those two personal motivations outlined, I present to you, for your consideration, the Razer x Lambda Tensorbook. A laptop with a no-compromise approach to speeds-and-feeds and shipping with OEM support for Ubuntu. sincerely, Vinay. Product Marketing @ Lambda April 13, 2022 at 12:12AM

Show HN: Multiplayer Demo Built with Elixir https://ift.tt/FuOAPVw

Show HN: Multiplayer Demo Built with Elixir Hey HN, I’m an engineer at Supabase [0] and one of the creators of this demo. 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 are sent database changes. The first check validates a JWT that is sent by clients subscribing to database changes. This JWT must contain an existing database role and optional claims, both of which can be referenced in Row Level Security (RLS) policies. Every valid client subscription is then inserted into the realtime.subscription table with an assigned UUID, database role, and claims. The second check calls the realtime.apply_rls SQL function from Write Ahead Log Realtime Unified Security (WALRUS) utility lib [3]. This function takes the database changes, executes a prepared statement to verify if the database role and claims have SELECT permissions on the changes, and outputs an array of authorized UUIDs. Then, the server finds all the subscribers whose UUIDs are in that array and broadcasts the changes to them. The next version of Supabase Realtime will offer three features: Broadcast, Presence, and Extensions. Broadcast, our Pub/Sub offering, can be used to pass ephemeral data from client to client such as cursor movements. This runs on a distributed cluster of nodes built on top of Phoenix PubSub + Channels. Presence, can be used for tracking online/offline users and their state. This is built into Phoenix, and uses replicated state across a cluster using an Observe-Remove-Set-Without-Tombstones (ORSWOT) CRDT [4] which prefers adds over removes when resolving conflicts. Extensions, are a way for the community to add additional functionality to take advantage of the WebSocket infrastructure. We have converted the existing Change Data Capture system to an extension that supports connecting to multiple customer databases (multi-tenancy). Other possible extensions include listening to other databases like MySQL and getting stock market events server-side [5], then broadcasting them to connected clients. This demo is built using a Supabase project, Supabase Realtime, and Next.js and deployed on 20 Fly [6] nodes located around the world. You can find an introduction and walkthrough of the demo here [5]. Supabase Realtime is entirely open source and you can find the demo code here [7]. Once we have stabilized the release we will add it to the self-hosted offering [8]. This demo is a way to highlight the upcoming features and gather feedback/ideas.

Show HN: Dev Toolbox – A browser extension with simple offline dev tools https://ift.tt/uDnXGwJ

Show HN: Dev Toolbox – A browser extension with simple offline dev tools Hello HN! I'd like to share a browser extension I made that provides quick offline access to various development tools. Current tool set: Calculate hashes; encode and decode HTML, URI, Base64; convert numbers between different bases; parse and manipulate various time formats; format and inspect IPv4/CIDR addresses; search all v13.1 emoji with quick copying in various formats. It runs entirely offline, making no external requests (even emoji PNG files are bundled), and only requires local storage permission to remember your last tab and input. This was inspired by an old extension called Hasher (no longer on the Chrome Store) that provided a simple interface to similar utilities. This was an opportunity to get back into making extensions, practice with Vue a bit, and expand upon the original idea. It's available for Chrome, Edge (via Chrome Store), and Firefox; links and screenshots are on GitHub, where you can also report any problems. Feedback and suggestions are very welcome. Thanks! https://ift.tt/p0sNCgl https://ift.tt/p0sNCgl April 10, 2022 at 01:13AM

Show HN: Programmatic – a REPL for creating labeled data https://ift.tt/dzHNJq9

Show HN: Programmatic – a REPL for creating labeled data 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 of boilerplate code and wrestle with pandas to understand what was going on. Building a dataset programmatically requires you to grok the impact of labeling rules on a whole corpus of text. We’ve been told that the exploration tools and feedback makes the process feel game-like and even fun (!!). We built it because we see that getting labeled data remains a blocker for businesses using NLP today. We have a platform for active learning (see our Launch HN [2]) but we wanted to give software engineers and data scientists a way to build the datasets needed themselves and to make best use of subject-matter-experts’ time. The package is free and you can install it now as a pip package [2]. It supports NER / span extraction tasks at the moment and document classification will be added soon. To help improve it, we'd love to hear your feedback or any success/failures you’ve had with weak supervision in the past. [1]: We use a HMM model for NER tasks, and Naive-Bayes for classification using the two approaches given in the papers below: Pierre Lison, Jeremy Barnes, and Aliaksandr Hubin.

Show HN: I made Million – It's a Virtual DOM made for the future https://ift.tt/jwoKsxC

Show HN: I made Million – It's a Virtual DOM made for the future 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 compiler to create predefined paths, instead of executing all the work in the browser. Hope this serves as an interesting example of how older technologies (relative to JavaScript time) can evolve to modern time (similar to how Solid took Knockout's fine-grained strategy and applied modern techniques) April 6, 2022 at 11:08PM

Show HN: ProductDiv – A Website Editor for Developers https://ift.tt/Em3Ilpk

Show HN: ProductDiv – A Website Editor for Developers I've been working on a library for developing websites visually. There are many tools for building websites, but none that fit my workflow as a front-end developer, so I made my own! It is an open source library called ProductDiv and it lets you: - Drag and drop any HTML template into your site. - Change elements with utility classes you can customize - Export clean HTML elements and copy into your source code. - Use in any framework! ProductDiv is developer-first, meaning the configuration for the editor lives in your source code. You can evolve the configuration as your project grows (as it inevitably will!). This lets you standardize design patterns and makes it easy to distribute high quality components to your team. I published a demo at https://ift.tt/WZSkoKE that includes Bootstrap 5 utility classes and some basic templates to experiment with. I would love your feedback on UX and to answer the big question: Would you use this in your project? Why or why not? https://ift.tt/WZSkoKE April 6, 2022 at 08:35PM

Show HN: Bloben – self hosted web CalDAV calendar client https://ift.tt/ltuDj9A

Show HN: Bloben – self hosted web CalDAV calendar client 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 mobile apps and decrypted only in Bloben client (with link to open from description). As part of this project I published also React calendar component https://ift.tt/TB5vFHM Thank you, if you are interested and feel free to ask me anything. April 6, 2022 at 11:53AM

I wanted something self-contained that helped me develop intuition rather than fluency. My hope is this is helpful for casual programmers, professionals from other fields who interact with code, or engineers who haven't had much exposure to interpreters or compilers. Hope this helps anyone else who's curious about getting a sense of Lisp and what makes it special with a limited time investment!
