Show HN: WhyBot, making GPT-4 question itself https://ift.tt/K9CzdNc

Show HN: WhyBot, making GPT-4 question itself Hi HN — we’re John and Vish! We built WhyBot, a tool to help you deeply explore a question or topic. You ask a question, and WhyBot responds by building an ever-expanding knowledge graph. It does this by recursively generating answers and follow-up questions. You can change its persona to change the flavor of the generations (try toddler mode!). We originally built this for the AngelList Agent Hackathon ( https://twitter.com/AqeelMeetsWorld/status/16502799744050421... ) and got a lot of interest from folks asking to play around with it. So we thought it’d be fun to brush it up and release it as a web app! It’s a work in progress and we plan on adding more features, such as saving, sharing, focusing on one branch and potentially executing code. We hope you enjoy playing around with it and would love to hear any of your feedback or thoughts. https://ift.tt/z6XGEpD May 14, 2023 at 09:47AM

Show HN: Infinity Whiteboard, Designed for Teachers https://ift.tt/jGo8DSL

Show HN: Infinity Whiteboard, Designed for Teachers I've created a whiteboard which I use every lesson when teaching maths, though it can be used for anything. It currently has a few hundred teachers using it daily. It's designed for use with touch-screen interactive whiteboards in classrooms, and stays in sync with your phone/tablet/whatever without signup/login. You can also find me on Twitter where I post updates etc: https://twitter.com/jakegmaths Some features and cool things: * Sync devices without signup - offline by default, just hit 'sync devices' and use the same code on multiple devices to sync * Touch-first - 1 finger draws; 2 finger pan/zoom; 3 finger gestures like changing pen colour * Add images - when teaching, this is usually photos of student work taken on my phone and auto-sync'd to the whiteboard at the front of the room * Add PDFs - when teaching, these are usually past paper exams which I then annotate over with the class * Zen mode - 3 finger tap or hit the ∞ icon to hide the UI; something I use every lesson so students can focus on the actual maths (there's also a fullscreen button when not on iOS) * Visualiser - often when teaching we'll work on paper with a webcam aka 'visualiser' pointing down at it; this projects that to the main whiteboard, with optional cropping, freeze-frame and snapshots * Screencast - many teachers use eg PowerPoint to teach; instead, I'll use PowerPoint in edit/design mode rather than slideshow mode, with a locally-cast cropped portion of that on the main whiteboard at the front of the room. This enables me to eg edit my PowerPoint as I go and use all the PowerPoint tools not available in slideshow mode * Instant replay - hit the play button to play back all the scribblings currently showing on the screen * Magnet mode - when sync'd with another device, use the magnet icon so the other device follows you. Most of my teaching is now via a tablet-with-stylus anywhere in the room, and as I pan/zoom around with the tablet the main whiteboard comes with me... but only when I want it to by activating the magnet * Student mini-whiteboards (MWBs) - if my students have devices and I want them to use them, I 'sync devices' then enable student MWBs and each student has a live copy of the whiteboard, and I can see what they write and can showcase any student instantly on the main board * PWA support - install as a PWA and you can download whiteboards as .iwb files which can then be double-clicked to open/edit on desktop * Free - I have no plans to charge for this Other things you may find interesting from a tech perspective: * The client is a single <5,000 lines HTML file, with JS, CSS, SVG-favicon all inlined (plus PDF.js lazily loaded if you add a PDF) * This is vanilla Javascript with no frameworks or libraries (except PDF.js) and no minification or build scripts - just view-source and check out how ugly all my code is! * 77.6kB for everything (except PDF support)... the size of 'modern' websites frankly disgusts me * The server is just a single ~500 line Javascript file and runs on Deno (also ported to Bun but unstable for now) and really just serves some static files, deals with websockets and temporarily stores images people add * Costs ~£5/month on Heroku * There's no database or any long-term persistence - Heroku servers restart every 24h and nothing is saved beyond that; it's all ephemeral https://www.mathsuniverse.com/infinity May 12, 2023 at 06:56PM

Show HN: Deterministic objective Bayesian inference for spatial models [pdf] https://ift.tt/OY9HwbN

Show HN: Deterministic objective Bayesian inference for spatial models [pdf] To give some context, objective Bayesian inference refers to Bayesian analysis (i.e. integrating over the parameter space) using a prior that is design to represent "minimal information" (see [1], [2], and [3] for an overview). Particularly in cases where a model's likelihood function is not strongly peaked about a point, objective Bayesian inference can give better results than methods based off of point estimates like Maximum Likelihood [4]. Reference priors provides a general approach to construct so-called noninformative priors that are suitable for Objective Bayesian analysis ([5], [6]). The approach takes a practical viewpoint of noninformative priors and looks to build priors that are both tractable and provide good performance on frequentist coverage simulations. See Section 2 for a description of how the process and frequentist simulations work and [7] for examples with some basic models (e.g. why 1/σ^2 is the noninformative prior for the variance of normally distributed data with known mean). [8] was the first to develop reference priors for Gaussian processes models, and [9] extended the work to handle Gaussian Processes with noise (or nugget effects). The project I'm working on provides software and algorithms to do deterministic inference using the prior from [9]. Typically, such inference has been done using MCMC sampling algorithms; but my belief is that deterministic algorithms can give results that are more consistent, less sensitive to parameter tweaking, and more efficient, at the expense of some engineering cost and loss of generality. For an example of how the algorithms work on a real-world data set of zinc measurements in a flood plain along the Meuse river [10], see https://ift.tt/Oc4NW8C...

Show HN: Build progressively enhanced reactive HTML apps using Go and Alpine.js https://ift.tt/Bf7ZrGk

Show HN: Build progressively enhanced reactive HTML apps using Go and Alpine.js Fir leverages Golang’s standard library html/template package and a bit of alpinejs to allow building reactive UIs. You start with plain old html and use alpinejs to enhance it to bring no-page-reload interactivity to web apps. The Fir toolkit is designed for Go developers with moderate html/css & js skills who want to progressively build reactive web apps without mastering complex web frameworks. It includes a Go library and an Alpine.js plugin. How it works ? On receiving user-interactions the fir server re-renders html templates and sends it over the wire where the fir client library selectively updates the changed areas. When a user event is received by a Fir route, an array of html templates are rendered on the server and returned as an array of DOM events to the browser. The DOM events are consumed by the alpinejs plugin and dispatched within the DOM where listeners attached to elements can use the event to update the DOM. See the demo and quickstart here: https://ift.tt/3ik67sX https://ift.tt/3ik67sX May 10, 2023 at 05:33AM

Show HN: Card game where players write their own cards that get parsed into code https://ift.tt/y1RtOUd

Show HN: Card game where players write their own cards that get parsed into code Wordbots is a long-running side project I've been working on on-and-off for the past ~7 years that I finally feel comfortable enough with to share with the HN community. It's an online tactical card game (inspired by games like Hearthstone and Magic: the Gathering), where players write their own cards in natural language, that gets parsed down to JavaScript. The English-to-JavaScript translation is handled by a semantic parser operating on a hand-crafted CCG grammar – kind of an “old-school” approach in this age of LLMs but one that performs quite well on the very constrained language of Wordbots cards. The resulting game gets pretty wacky as players can create all sorts of cards, though there are some game formats that try to produce more balanced gameplay as well (e.g. one format in which both players shuffle their decks together, and various draft formats). If you're curious about how it all works, I made a write-up about it here: https://ift.tt/pnCYHbk And if you want to chat about Wordbots beyond this thread, please don't hesitate to join our discord at https://ift.tt/5ak4Kls .

Show HN: Cptn.io – open-source integration platform https://ift.tt/QKwRqOx

Show HN: Cptn.io – open-source integration platform Hi, I am Krishna Thota. I am building an open source integration and data platform( https://cptn.io ). The product is MIT licensed and the repo is at https://ift.tt/waJXNHq . I have started on my startup journey an year ago and launched a monitoring platform called DevRaven. Unfortunately the product did not takeoff as expected. That story is for another day. But during the course of building the product, I have built several integrations leveraging MQs and Cloud Functions. While building and deploying Cloud Functions for happy paths is easy, I had to monitor logs for failures, build retry mechanisms or manually process failed events, keep instances running to prevent cold start timeouts. It can also get expensive with charges for MQs, server time for running cloud functions etc and costs can be unpredictable. I thought of building a platform where I can build integrations quickly, have the ability to look at incoming/outgoing events, look at logs, retry any failed events etc. And finally, predictable costs for running the infrastructure. cptn.io provides all these capabilities and more. You can build pipelines to integrate with any cloud services, send data from your backend to data warehouses, listen to web hook events etc. The platform can be integrated into any stack by sending events to HTTP end points. Instead of trying to build a business first or launch an open source product under restrictive licenses, the platform will be available under MIT license so any user or customer can use it. There is no ee folder or complex dual licensing and I am also committing to releasing SSO under MIT. The plan is to offer a managed service in the cloud at a later time, accept sponsors for prioritizing features for enterprise customers and charge for enterprise support. It should take less than 5 minutes to get the platform running on your machine. Welcome any feedback, feature requests, PRs and bug reports. https://cptn.io May 8, 2023 at 11:15PM

Show HN: Play SineRider, a math puzzle game built by teenagers at Hack Club Messing with your TI-84 graphing calculator is a rite of passage for every teenager who has ever been bored in a math class. In 2013 I was that teenager, and it gave me an idea for a tiny game about sledding on graphs. This project grew into my white whale, and I spent my twenties trying and failing to finish it alone. I shelved the game when I started working for Hack Club in 2018—until last May, when a few community members took it off the shelf. The project took on a life of its own, and turned into a year of nights and weekends from a global team of 20+ teens in 8+ countries. Today SineRider enters public beta! SineRider is literally an infinite universe of function composition puzzles, each with infinite solutions, that range from welcoming for 9th graders to difficult for even the most serious matlab user. And every day we tweet out a fresh one to be solved with your morning coffee. We hope you enjoy playing SineRider as much as we’ve enjoyed making it. And we’re not done! Mobile support, polar coordinates, and a level editor are all on the roadmap. SineRider is a living project, to be continuously built and maintained as free OSS by the Hack Club community: https://ift.tt/3blAt1O The team that built the game will try to be in the comments today between high school classes and AP tests. —chris walker, creative director Watch the trailer: https://www.youtube.com/watch?v=35nDYoIwiA8 Play now: https://sinerider.com https://ift.tt/3blAt1O May 8, 2023 at 06:44PM

Show HN: AI Poetry Contest Hi HN! Me and my buddy made this in a weekend as an experiment in 1. building something quickly and putting it out there and 2. using AI in an interesting way; in this case a poetry judge. Our “judge” isn’t perfect, but the hope is that at least it’s a relatively fair system that everyone can be sure evaluates their work. Anyway, we wanted to see what the lovely people of HN think of it. Some background on the idea; I like poetry and thought it would be cool if there was a big competition with a large financial incentive that scales with the number of participants. Using AI as a judge allows us to handle any number of submissions in a consistent and fair way. It also opens up the competition to poetry written in other languages, although for now we’re only promoting in the US. Happy to answer any questions! Also any feedback is much appreciated, thanks! https://ift.tt/U5SprNV May 8, 2023 at 04:51AM

Show HN: Git Hooting https://ift.tt/K3asRoH

Show HN: Git Hooting 00's called, they want their RSS feeds back. I was looking at my growing Github gist collection when a sudden urge to blog and make a name for myself "by not programming" struck. Part way into implementing my oh so special static website generator it occurred to me that, quite frankly, Github gists is a pretty decent publishing platform. I mean, it gives you reasonably extended markdown with previews, heck I could even write in org-mode, has comments, follower - followee relationship, extended search with filters, check out locally and push your edits. Did someone say "edit button"? Thus the idea behind https://git.ht was born: collect gists into RSS feeds and force everyone, kicking and screaming, into the good old days when Google Reader was king. Well, it's a bit more than that now. But basically, you create a gist or grab an old one, name its main file `hoot.md` or `hoot.org` if org-mode is your poison, make it public and voila. These "hoots" make it into your RSS feed and will get permalinks with social graph metatags, so you get nice previews when you share them on Twitter and such. To take it for a spin: - pick a subdomain e.g. foo.git.ht, - navigate you browser there, - login with Github. I still consider it alpha, but it should work.

Show HN: Ethereum address reviews, similar to Yelp https://ift.tt/bHcP20z

Show HN: Ethereum address reviews, similar to Yelp Hi HN, Excuse me if the formatting sucks, this is a first time post. I want to introduce to you vrfd.info. A place where you can openly view and influence the reputation of any Ethereum address. Think of it as Yelp but for Eth. Addresses are classified as either verified or flagged on-chain through soulbound NFTs. A type of NFT that has no trade value as it cannot be sold. Once minted, it is stuck to the given address. The metadata of the NFT contains either information to verify the address with, this could be a social account for example. Or in the case of flagged addresses, the metadata contains proof of wrong-doing. Users can search the classification status of any address on the web app. Additionally, users can apply to either verify or report an address, provided proof. In the case of reports, users stand a chance to be rewarded. Finally, users can up or down vote other addresses. I made this tool after suffering one to many scam without having an open source library where addresses can be reported or their credentials verified. It's still a bit clunky, but the core concept works fully integrated on the Testnet. I'm shipping a big update this week to make it more responsive. Thanks for taking the time to read this. Please give me any feedback as I am looking to improve everywhere I can. https://vrfd.info May 5, 2023 at 11:00PM

Show HN: Avoiding Imgur Link Rot https://ift.tt/dBFyhqT

Show HN: Avoiding Imgur Link Rot Over the last decade I've built a number of different digital asset managers (mostly media files) that met the needs of my companies at the time. It is an area I enjoy working in. A month ago, when asked what was next for me, I jokingly said I would build another DAM. Then on Saturday, two weeks ago, I learnt that Imgur was going to delete all anonymous & NSFW files on the 15th of May. It was pointed out that this would mean broken links in communities that had relied on Imgur. By the Sunday I had decided that I would build another DAM, initially with the intent of avoiding Imgur link rot. It was challenging to find time to spend on this, the project was put together over about 8 evenings. It still has rough patches, this is an early MVP (a Michael Seibel "brick"). I have many ideas of where to take this project, but for now it only does one thing: backup Imgur files and produce new links that are easy to swap out for old soon-to-be-deleted Imgur links. https://haasie.com May 6, 2023 at 04:10AM

Show HN: Hypertune – Visual, functional, statically-typed configuration language https://ift.tt/rT1uvqn

Show HN: Hypertune – Visual, functional, statically-typed configuration language Hey HN! I'm Miraan, the founder at Hypertune, and I'm excited to be posting this on HN. Hypertune lets you make your code configurable to let teammates like PMs and marketers quickly change feature flags, in-app copy, pricing plans, etc. It's like a CMS but instead of only letting you set static content, you can insert arbitrary logic from the UI, including A/B tests and ML "loops". I previously built a landing page optimization tool that let marketers define variants of their headline, CTA, cover image, etc, then used a genetic algorithm to find the best combination of them. They used my Chrome extension to define changes on DOM elements based on their unique CSS selector. But this broke when the underlying page changed and didn't work with sites that used CSS modules. Developers hated it. I took a step back. The problem I was trying to solve was making the page configurable by marketers in a way that developers liked. I decided to solve it from first principles and this led to Hypertune. Here's how it works. You define a strongly typed configuration schema in GraphQL, e.g. type Query { page(language: Language!, deviceType: DeviceType!): Page! } type Page { headline: String! imageUrl: String! showPromotion: Boolean! benefits: [String!]! } enum Language { English, French, Spanish } enum DeviceType { Desktop, Mobile, Tablet } Then marketers can configure these fields from the UI using our visual, functional, statically-typed language. The language UI is type-directed so we only show expression options that satisfy the required type of the hole in the logic tree. So for the "headline" field, you can insert a String expression or an If / Else expression that returns a String. If you insert the latter, more holes appear. This means marketers don't need to know any syntax and can't get into invalid states. They can use arguments you define in the schema like "language" and "deviceType", and drop A/B tests and contextual multi-armed bandits anywhere in their logic. We overlay live counts on the logic tree UI so they can see how often different branches are called. You get the config via our SDK which fetches your logic tree once on initialization (from our CDN) then evaluates it locally so you can get flags or content with different arguments (e.g. for different users) immediately with no network latency. So you can use the SDK on your backend without adding extra latency to every request, or on the frontend without blocking renders. The SDK includes a command line tool that auto-generates code for end-to-end type-safety based on your schema. You can also query your config via the GraphQL API. If you use the SDK, you can also embed a build-time snapshot of your logic tree in your app bundle. The SDK initializes from this instantly then fetches the latest logic from the server. So it'll still work in the unlikely event the CDN is down. And on the frontend, you can evaluate flags, content, A/B tests, personalization logic, etc, instantly on page load without any network latency, which makes it compatible with static Jamstack sites. I started building this for landing pages but realized it could be used for configuring feature flags, in-app content, translations, onboarding flows, permissions, rules, limits, magic numbers, pricing plans, backend services, cron jobs, etc, as it's all just "code configuration". This configuration is usually hardcoded, sprawled across json or yaml files, or in separate platforms for feature flags, content management, A/B testing, pricing plans, etc. So if a PM wants to A/B test new onboarding content, they need a developer to write glue code that stitches their A/B testing tool with their CMS for that specific test, then wait for a code deployment. And at that point, it may not be worth the effort. The general problem with having separate platforms is that all this configuration naturally overlaps. Feature flags and content management overlap with A/B testing and analytics. Pricing plans overlap with feature flags. Keeping them separate leads to inflexibility and duplication and requires hacky glue code, which defeats the purpose of configuration. I think the solution is a flexible, type-safe code configuration platform with a strongly typed schema, type-safe SDKs and APIs, and a visual, functional, statically-typed language with analytics, A/B testing and ML built in. I think this solves the problem with having separate platforms, but also results in a better solution for individual use cases and makes new use cases possible. For example, compared specifically to other feature flag platforms, you get auto-generated type-safe code to catch flag typos and errors at compile-time (instead of run-time), code completion and "find all references" in your IDE (no figuring out if a flag is in kebab-case or camelCase), type-safe enum flags you can exhaustively switch on, type-safe object and list flags, and a type-safe logic UI. You pass context arguments like userId, email, etc, in a type-safe way too with compiler errors if you miss or misspell one. To clean up a flag, you remove it from your query, re-run code generation and fix all the type errors to remove all references. The full programming language under the hood means there are no limits on your flag logic (you're not locked into basic disjunctive normal form). You can embed a build-time snapshot of your flag logic in your app bundle for guaranteed, instant initialization with no network latency (and keep this up to date with a commit webhook). And all your flags are versioned together in a single Git history for instant rollbacks to known good states (no figuring out what combination of flag changes caused an incident). There are other flexible configuration languages like Dhall (discussed here: https://ift.tt/VaxFgmn ), Jsonnet (discussed here: https://ift.tt/ZVcvKlX ) and Cue (discussed here: https://ift.tt/2MYzgSd ). But they lack a UI for nontechnical users, can't be updated at run-time and don't support analytics, A/B testing and ML. I was actually going to start with a basic language that had primitives (Boolean, Int, String), a Comparison expression and an If / Else. Then users could implement the logic for each field in the schema separately. But then I realized they might want to share logic for a group of fields at the object level, e.g. instead of repeating "if (deviceType == Mobile) { primitiveA } else { primitiveB }" for each primitive field separately, they could have the logic once at the Page level: "if (deviceType == Mobile) { pageObjectA } else { pageObjectB }". I also needed to represent field arguments like "deviceType" in the language. And I realized users may want to define other variables to reuse bits of logic, like a specific "benefit" which appears in different variations of the "benefits" list. So at this point, it made sense to build a full, functional language with Object expressions (that have a type defined in the schema) and Function, Variable and Application expressions (to implement the lambda calculus). Then all the configuration can be represented as a single Object with the root Query type from the schema, e.g. Query { page: f({ deviceType }) => switch (true) { case (deviceType == DeviceType.Mobile) => Page { headline: f({}) => "Headline A" imageUrl: f({}) => "Image A" showPromotion: f({}) => true benefits: f({}) => ["Ben", "efits", "A"] } default => Page { headline: f({}) => "Headline B" imageUrl: f({}) => "Image B" showPromotion: f({}) => false benefits: f({}) => ["Ben", "efits", "B"] } } } So each schema field is implemented by a Function that takes a single Object parameter (a dictionary of field argument name => value). I needed to evaluate this logic tree given a GraphQL query that looks like: query { page(deviceType: Mobile) { headline showPromotion } } So I built an interpreter that recursively selects the queried parts of the logic tree, evaluating the Functions for each query field with the given arguments. It ignores fields that aren't in the query so the logic tree can grow large without affecting query performance. The interpreter is used by the SDK, to evaluate logic locally, and on our CDN edge server that hosts the GraphQL API. The response for the example above would be: { "__typename": "Query", "page": { "__typename": "Page", "headline": "Headline A", "showPromotion": true } } Developers were concerned about using the SDK on the frontend as it could leak sensitive configuration logic, like lists of user IDs, to the browser. To solve this, I modified the interpreter to support "partial evaluation". This is where it takes a GraphQL query that only provides some of the required field arguments and then partially evaluates the logic tree as much as possible. Any logic which can't be evaluated is left intact. The SDK can leverage this at initialization time by passing already known arguments (e.g. the user ID) in its initialization query so that sensitive logic (like lists of user IDs) are evaluated (and eliminated) on the server. The rest of the logic is evaluated locally by the SDK when client code calls its methods with the remaining arguments. This also minimizes the payload size sent to the client and means less logic needs to be evaluated locally, which improves both page load and render performance. The interpreter also keeps a count of expression evaluations as well as events for A/B tests and ML loops, which are flushed back to Hypertune in the background to overlay live analytics on the logic tree UI. It's been a challenge to build a simple UI given there's a full functional language under the hood. For example, I needed to build a way for users to convert any expression into a variable in one click. Under the hood, to make expression X a variable, we wrap the parent of X in a Function that takes a single parameter, then wrap that Function in an Application that passes X as an argument. Then we replace X in the Function body with a reference to the parameter. So we go from: if (X) { Y } else { Z } to ((paramX) => if (paramX) { Y } else { Z } )(X) So a variable is just an Application argument that can be referenced in the called Function's body. And once we have a variable, we can reference it in more than one place in the Function body. To undo this, users can "drop" a variable in one click which replaces all its references with a copy of its value. Converting X into a variable gets more tricky if the parent of X is a Function itself which defines parameters referenced inside of X. In this case, when we make X a variable, we lift it outside of this Function. But then it doesn't have access to the Function's parameters anymore. So we automatically convert X into a Function itself which takes the parameters it needs. Then we call this new Function where we originally had X, passing in the original parameters. There are more interesting details about how we lift variables to higher scopes in one click but that's for another post. Thanks for reading this far! I'm glad I got to share Hypertune with you. I'm curious about what use case appeals to you the most. Is it type-safe feature flags, in-app content management, A/B testing static Jamstack sites, managing permissions, pricing plans or something else? Please let me know any thoughts or questions! https://ift.tt/qgJX6G9 May 4, 2023 at 08:31PM

Show HN: USearch – Smaller and Faster Single-File Vector Search Engine https://ift.tt/bumBJa7

Show HN: USearch – Smaller and Faster Single-File Vector Search Engine Last week was insane for vector search. Weaviate raised $50M, and Pinecone raised $100M... That's a lot and makes you believe that vector search is hard. But it's not. I have spent the last couple of days implementing a single-file vector search engine from scratch, which is at least the tenth in the twenty years of my career. But this time, it's different. Instead of inventing a brand new algorithm and doing some crazy optimizations on the GPU, I: 1. took the standard HNSW algorithm, 2. fitted into 1000 lines of C++11 for portability, 3. added quantization and hardware-accelerated metrics, 4. wrapped for Python, JavaScript, Rust, and Java, and 5. open-sourced it! It was fun, and to my surprise, it performed well, reaching 300K QPS on Amazon c7g instances. I never had to use third-party vector search products, but the first testers of USearch suggested 3x performance improvement over their existing solutions. My colleagues and friends are also adding bindings for GoLang and the Wolfram language. We will soon add Windows support, a standalone server, and a distributed version based on UCall we shared a month ago. There are, of course, but you can already use it! One of the apparent use cases is Semantic Search platforms. The example at the end of the GitHub page shows how to use USearch, UCall, and the UForm transformers together to build up a text-to-image semantic search platform in just 20 lines of Python. Try it and join the development! We also have a lot of open positions, especially for those who want to work with us on next-get algorithms and AI infra rather than polishing and repackaging existing ideas :) https://ift.tt/RsNOqt7 May 3, 2023 at 09:03PM

Show HN: Diofanti.org Tracking government decisions in Greece https://ift.tt/OCbJ3Sz

Show HN: Diofanti.org Tracking government decisions in Greece Hello HN, I'm Florents, and I'm a data engineer based in Greece. I've developed Diofanti.org , an application that tracks public spending and government procurement & decisions in Greece. Here's the big picture: There's diavgeia.gov.gr (diavgeia kinda translates to "transparency") where all Greek state organizations (think ministries, authorities, municipalities, regions) should publish their executive decisions. There are roughly 20K decisions published daily (Greece has a population of 11M). If a decision is not openly published, it cannot be executed legally. So it is a legal prerequisite. A decision could be a payment from a municipality or ministry to a vendor, a procurement of software licenses, or even a parking permit to a disabled citizen. Now, decisions are typically published as PDF documents (with all the legal jargon and details), which makes the law happy but doesn't say much to the average citizen; There's also an API, though, and diofanti taps on that to fetch and analyze those decisions and make them easy to visualize and analyze. So the use cases diofanti supports are like the following: • How much did my hometown pay during the last week? Which vendors are the most frequent receivers? • What are the decisions that my local town makes and that I should know about? • For non-financial decisions, one could go back in time and assess a state's stance on a particular issue. For example, a few years back, diofanti was used to uncover anti-abortion campaigns financed by some state organizations. As you might expect, it's become very popular among journalists and political (opposition) parties. The reason I'm publishing this on HN is to ask the following: 1. Do you have any pointers to similar efforts in other countries? 2. Any ideas to make this better ? 3. Forward this to anyone / any organization that you think would like to support financially Additional material * Blog post describing the thinking behind this [0] (in Greek, but can be translated easily): * Demo video [1] 0: https://ift.tt/p7nil49 1: https://youtu.be/vdpHyxQqyWQ https://diofanti.org May 2, 2023 at 06:48PM

Show HN: Jarvis AI – Text, iMessage, and Email ChatGPT https://ift.tt/BvMsA9D

Show HN: Jarvis AI – Text, iMessage, and Email ChatGPT We're back with another ShowHN! When we launched, you could text Jarvis AI using regular SMS messages from your phone. Since launching 3 weeks ago[1], we've introduced two new channels for using ChatGPT. Now you can use ChatGPT over SMS text message, iMessage for Apple-enabled devices, and via Email. It is super interesting to forward an email to Jarvis AI and see its thoughts on your email thread. It can help you brainstorm or it can suggest a reply to previous emails. 10 messages free forever, more volume is free over iMessage and Email for a limited time (until the HN hug of death!). You don't have to sign up or anything to try it. Just send a text to: +1 (855) 676-1two89. Thanks for checking this out. Many exciting features are coming soon to make this more than just a different interface to ChatGPT. We want to make AI accessible to more people, over more channels, with more useful things for your day-to-day. For medical professionals, we added the /diagnose command. Ask Jarvis "/diagnose 32 year old harsh cough" for example. Soon, we are adding features like /invoice for generating invoices and /remember for notes and reminders.

Show HN: Code-Narrator: Automating Documentation with GPT-4 https://ift.tt/ab36GPq

Show HN: Code-Narrator: Automating Documentation with GPT-4 As a solo developer on a sizeable project, I found myself facing the challenge of creating documentation, a task I admittedly do not enjoy. Fortunately, ChatGPT arrived just in time. After experimenting with it, I discovered that it generates high-quality documentation for code files, even better than what I could produce manually. This realization led me to develop Code-Narrator, a client that simplifies the documentation process. Code-Narrator ( https://ift.tt/Ohn3GAd ) utilizes GPT-4 to analyze your code files and automatically generate documentation. The tool is language-agnostic and has been tested with TypeScript, GraphQL, Solidity, C#, Kotlin, and more. As long as the files are in plain text, Code-Narrator should work seamlessly. The primary goal of Code-Narrator is to ease the documentation process for developers, transforming them from writers to editors. While developers are still responsible for verifying the accuracy of the generated documentation, the initial writing is handled by the AI. If GPT-4 produces incorrect documentation, it typically indicates that the code needs clarification, or a brief comment should be added to guide the AI. A general rule of thumb is that if GPT-4 cannot comprehend the code, it may be too complex for the next developer. However, Code-Narrator is constrained by GPT-4's 8192-token limit, which can be problematic for extensive code files. Those with access to the gpt-4-32k variant should expect better results. Upon its first run, Code-Narrator creates a configuration file by analyzing your project, and then prompts you to review it for accuracy. The key configuration aspects include the "include," "config_files," and "source_path" settings. In its second run, Code-Narrator generates documentation for your entire project. The process is time-consuming, taking approximately 45 minutes to complete from scratch. However, the tool is: - Flexible, allowing for the creation of custom pages such as How-To guides, tutorials, FAQs, READMEs, and other bespoke content. - Multilingual, supporting 25+ languages (as many as GPT-4 supports). - Versatile, capable of generating documentation in various formats (LaTeX, HTML, with the default being Markdown). For a demonstration on transforming a few lines into a How-To guide, watch this video: https://www.youtube.com/watch?v=uJtVCUOTkvw . Remember that brevity is key, as the more concise the input, the more GPT-4 can contribute. Code-Narrator also supports custom plugins, with tutorials available at https://ift.tt/pAv16ws... . In terms of size and cost, Code-Narrator consists of 45 files and 1712 lines of code. The total cost of generating documentation for the entire project is approximately $2.5, a significant savings compared to manual documentation. During the development of Code-Narrator, I noticed several benefits: - Improved function naming: Reading the generated documentation led me to revise vague or overly general function names, resulting in better code and documentation. - Concise input: Focusing on reducing the size of the input file (liquid) became a fun challenge, helping to optimize the process. - Enjoyable interaction: Working with ChatGPT proved more enjoyable than manually writing documentation, and the more I experimented, the better the results. - Minimal input for tutorials: I was pleasantly surprised by how little input was required to create How-To guides and tutorials using GPT-4. - Encouragement to refactor: The 8K token limitation may be restrictive, but it also encourages developers to refactor their code for improved readability and structure. As a prototype and proof of concept, Code-Narrator has some limitations. I'm excited to see where Code-Narrator goes from here, and your feedback is invaluable. Thank you for taking the time to explore this project! https://ift.tt/Ohn3GAd April 28, 2023 at 03:49PM

Show HN: ScrapScript – A tiny functional language for sharable software Hi friends, I started casually working on scrapscript in 2015. I built a few compilers over the years to test out various ideas/implementations, and I think I'm finally happy with the overall design. The code is not public yet. Email me at hello@taylor.town if you're interested in joining the core team later this year. Let me know if you have any questions or feedback :) https://scrapscript.org April 26, 2023 at 05:15PM

Show HN: GraphAr – An Open-Source File Format for Graph Data Archive/Exchange https://ift.tt/CGOiWK8

Show HN: GraphAr – An Open-Source File Format for Graph Data Archive/Exchange Hi, Hacker News! We're excited to announce the release of GraphAr, an open-source file format for archiving and exchanging graph data. The landscape of graph processing systems is fragmented, with various types of systems, including graph databases, graph computation systems, and GNN systems. However, currently, there is no common file format for efficiently storing and exchanging graph data while maintaining its schema and graph semantics. GraphAr is designed to address this issue by providing a simple, lightweight format for storing and exchanging graph data. GraphAr is a flexible and adaptable format that can be used across a variety of applications by decoupling the storage of metadata, adjacency, and properties. It is also designed to be efficient by leveraging existing formats such as ORC, Parquet, and CSV as much as possible. This makes it easy to integrate with existing data processing systems and provides a level of familiarity for users. Furthermore, GraphAr preserves the semantics of graphs and can maintain the schema of property graphs. This means that users can maintain the same graph structure across different systems, ensuring that the graph's semantics are not lost. We have developed both a C++ library for accessing and creating GraphAr files, and a Spark library for transforming data into and from GraphAr files. With these libraries, it's easy to work with GraphAr files in your existing Spark connectors or C++ projects. As GraphAr matures, we aim to move the project to a vendor-neutral venue, such as Apache, LF AI & Data. This will ensure that the project continues to be developed in an open and transparent manner, with contributions from a broad community of developers. To get started with GraphAr, check out our GitHub repository, where you'll find detailed documentation and examples of how to use the libraries. We welcome any feedback or contributions to the project. Let's make graph data archiving and exchange more efficient with GraphAr! https://ift.tt/QA2mRIf April 27, 2023 at 07:46PM
