Show HN: lambdaprompt – build, compose and call templated LLM prompts For the past few months I've been building a lot of things with LLMs (GPT-3, Codex, etc.) as I've been trying to push them to their limits (especially towards applying them to the tabular data domain) When working on this, I've found there are some common patterns for solving problems (templating, chaining, functional-programming style operations, etc.) As I've iterated, I've come to believe that a functional style interface is likely going to power a new wave of systems I'm calling "prompt-machines"(systems where the core new unit of work is a "named" LLM prompt, extending the "function" concept). Additionally, in order to make the code capable of meta-prompting (where the LLM can write its own templated prompts), I aimed to make the interface and library as simple and lightweight as possible. I think I've achieved my goal, so I'm releasing the library to share with others! I mainly use lambdaprompt in two main ways: (1) to quickly try out "map" applying a LLM prompt against multiple inputs, to see how it behaves on a fixed set of inputs (2) to quickly iterate on a prompt-chain (taking the output of a prompt, and passing it to other prompts) to create complex behavior. An example of (2) that worked quite well is a Text-2-SQL prototype: It generates multiple SQL options, then executes each against the database (if it errors, asks `Codex-EDIT` to fix the errors and retry), then takes the most "consistent" answer as the valid answer. Simply by adding this prompt-chain on top of codex, we saw an improvement from ~75% to ~85% on a spider Text-2-SQL benchmark (On just a small sample of N=200). To increase usability it also ships (extras) with a fastapi app that registers any defined prompts as endpoints directly, and hosts the functions to be directly callable via HTTP-GET requests. This makes it easy to build client-applications off of these prompts, while allowing the prompt itself to be arbitrarily complex (composition of prompts) I hope you enjoy using it! Also, I'm super curious to hear if anyone else has been thinking about LLMs (composing them, building interfaces to them, etc.) in similar ways and what learnings have been (even if not though this library) https://ift.tt/crDLPs6 December 31, 2022 at 04:13AM

Show HN: I built a simple CLI helper integrating with GPT-3 https://ift.tt/d74CGke

Show HN: I built a simple CLI helper integrating with GPT-3 Hi all! I don’t think CHATGPT has gone unnoticed by anyone here on Hackernews. I’ve myself played around a bit with it, but felt it was annoying to always have to log into their GUI to ask the questions. To scratch my own itch and at the same time learn more about how to write my own command line interface, I created 'askai'. 'askai' is a simple CLI integration with OpenAI’s GPT3 models. I’ve primarily used it to get quick answers to technical questions, like: > askai "How to mock user input when writing a Python pytest test?" > askai "How do I remove a conda environment?" As I've found it quite helpful, I decided to spend some time to package it in a nicer way to share it with all of you. I've also uploaded it to PyPI to simplify the installation process. 'askai' enables you to: * Ask questions and get the answers straight into your terminal * Configure which model and model parameters you want to use * Overwrite saved configurations when you ask questions Currently, it only supports OpenAI’s models, but my plan is to integrate more endpoints as soon as new capable NLP endpoints are popping up. I hope some of you find it useful :) https://ift.tt/x0oyglk December 27, 2022 at 11:29AM

Show HN: Eleven – open-source alternative to Codespaces https://ift.tt/ZpfQ2C8

Show HN: Eleven – open-source alternative to Codespaces Hey HN, Eleven is the second project that I've built to learn Go. It lets you create a code sandbox in your cloud provider account easily. What's a "code sandbox"? Just a VM, running in your cloud provider account, with some runtimes pre-installed, your repositories cloned, a way to connect to it with your preferred editor (or via SSH) and a way to serve your apps easily via HTTP (with automatic HTTPS). You could use it to deploy your app, as a remote development environment or even to test some code. It's up to you. For example, to deploy a Node.JS app: $ eleven aws init hello-world --runtimes node@18.7.0 --repositories eleven-sh/hello-world > Success! The sandbox "hello-world" was initialized. $ ssh eleven/hello-world forever node index.js > Forever: command started. Run "forever stop" in current path to stop. $ eleven aws serve hello-world 8000 --as hello.eleven.sh > Success! The port "8000" is now reachable at: https://hello.eleven.sh $ curl https://hello.eleven.sh > Hello World Still learning Go by the way, so I'm open to any suggestions to improve. https://ift.tt/1fNq9RP December 26, 2022 at 05:27PM

Who knew? While there are plenty of good guides for 2D and 3D graphics and physics, there's not much out there for 4D. In hopes of alleviating that, the code here is arranged such that the commits are more or less a step-by-step guide, with comments for the interesting or tricky parts.

I work mainly with React at work, as data is passed down as props, we end up performing a lot of transformations and checks on it. Most React developers leverage arrays heavily because the intuitive immutable, chainable API that JS arrays offer works really well with React's functional model. The purpose of this library is to make other types of data just as easy to work with by mirroring the Array API whenever possible, keeping immutability and chaining as first class features. It is not just for React developers, but anybody who has to manipulate data and hates having to write `if` statements.

Show HN: A vichan variant that ChatGPT helped me host https://ift.tt/w7jvRsx

Show HN: A vichan variant that ChatGPT helped me host I recently set up a website hosting vichan [0] with nginx, and named it "h2ochan", inspired by the chaotic (yet moderated!) nature of imageboards like 4chan and 2chan. Plus, I love having a liter of water within arm's reach at all times. In the future, I have some plans for threading and posts that will further emphasize the "water" theme and encourage community engagement. In the past, I had tried setting up vichan a few times, but I was overwhelmed by the many technical tasks involved, such as using a remote terminal, working with MySQL databases, configuring nginx, setting file permissions and owners, and using Emacs (or trying to avoid clunky local file edits and FTP). However, I recently discovered chatGPT and have found it very helpful in assisting me with various technical issues. I began by asking for help setting up a public PHP forum, saying that I was a gamedev with some experience in Unity and C#, but not familiar with web development. chatGPT recommended that I look into ASP.NET [1] (which is similar to C#) and gave me some specific recommendations for webhosts and domain registrars. Based on these recommendations, I was able to get a Shared Windows Host [1] up and running, with my nginx [3] page visible after visiting the proper IP address. During the vichan installation process, there is a config-help screen that shows red and yellow lights, to show stuff like if vichan is missing permissions, the SQL database is misconfigured, etc. Initially, this screen showed about three errors and five warnings, mostly related to vichan's inability to read or write certain files. ChatGPT was very helpful in troubleshooting these issues, whether I copy-pasted error messages or described the problems in my own words. It helped me with tasks such as using `chmod`, `chroot`, and `grep`, as well as with fixing HTTP status codes such as 403 Forbidden, 404 Not Found, and 500 Internal Server Error [2]. ChatGPT also helped me locate log files and fix other issues, and eventually all of the warnings were resolved. Emacs was also very helpful during the setup, with chatGPT assisting with emacs commands (I have a double-sided Sheet of them somewhere...) Although I am still learning basic hotkeys, I am able to Save, Undo, and Quit with confidence, and I have almost memorized the Page Up/Down keys. I was initially drawn to Emacs because I saw a page about hotkeys for capitalizing, lowercasing, and uppercasing words years ago, but never sticking with it. Now using it more, my thoughts still being "My smartphone can't even Delete (forward) or Undo! Modifying whole WORDS like this is incredible!" Please go look at h2ochan, and Drink Water! [0] https://ift.tt/hAXuZK2 [1] I did have to switch from a Shared/managed ASP.NET to a Dedicated Linux Host, since remote SSH was not supported for Windows, only Linux [2] I forgot two of these error codes, so I asked chatGPT to remind me of ones I might have encountered during setup. chatGPT also revised my initial post (making sure chatGPT got a [] citation, no matter how confusing!) which I revised once more before posting. [3] Windows + nginx, huh? I may be mis-remembering this bit, but there was certainly a point of realizing "I need Admin access so I can edit Permissions..." or something, and that Windows without SSH was wholly insufficient for vichan [-] chatGPT was occasionally a bit outdated, which led to missing packages, non-existent paths, and imperfect configurations. However, it seemed happy to accept corrections, such as when I wanted to show line numbers in PHP files in Emacs, but my init.el file already had a setting to show line numbers for all programming languages, and I didn't have php-mode installed. Instead, I needed to use phps-mode. [-] The website favicon is a Koreisha mark, hue-shifted to the Blues. It's used in Japan to signify elderly drivers, and used Abroad by Car Enthusiasts. I love the Half-Teardrops in contrasting Bright and Subtle Blue. https://www.h2ochan.org December 19, 2022 at 11:44PM

Show HN: Infisical – open-source secrets manager https://ift.tt/640VUpx

Show HN: Infisical – open-source secrets manager Last month, we open-sourced Infisical ( https://ift.tt/BbRfa5z ) - a simple, end-to-end encrypted tool to sync environment variables across your team and infrastructure. You can use it to store environment variables and inject them into your applications locally or into CI/CD and production infrastructure. It can be used with any language/framework and is platform independent with a super easy setup. We know secret managers exist but, in our experience, they’re too complicated, not comprehensive, not user-friendly, or a mix of all three — other nicer ones are closed-source and don’t have self-hosted options available. That’s why we’re on a mission to make secret management more accessible to every developer — not just security teams. We’ve launched this repo under the MIT license so any developer can use the tool. The goal is to not charge individual developers. We make money by charging a license fee for some future enterprise features as well as providing a hosted version and support. In the coming weeks, we plan to add features like key rotation, access logs + more integrations. We’d love to hear your thoughts and any feature requests! Give it a try ( https://ift.tt/BbRfa5z ), and let us know what you think! Main website: https://infisical.com/ https://ift.tt/BbRfa5z December 19, 2022 at 12:52PM

Show HN: The easiest way to run a brainstorm, supercharged with A.I Hello friends! We've been working hard on building Mimosa, and would love for you to try it! No signups required. Facilitating brainstorming sessions can be a challenging and time-consuming task. It's difficult to keep everyone on agenda, engaged, and contributing. So we've built Mimosa to be the easiest way to facilitate a brainstorming session. Imagine if a "digital whiteboard" and a "trello board" had a baby, but built with all the best practices of professional facilitation. With Mimosa, you can minimize bias by allowing team members to contribute anonymously before revealing their ideas. This ensures that everyone has a fair chance to share their thoughts and ideas without fear of judgment. Once the brainstorming session is complete, you can easily view and export the final results. This allows you to keep track of a meeting's effectiveness and share it with stakeholders. But the real game-changer is our AI Brainstorming features and it's ability to turn your 1x team into a 10x team. It help generates and collaborates with you in your brainstorming session to help you come up with more and better ideas. We're both scared and excited to hear all your thoughts, HN! :) Please do let us know any features or improvements you think we should make to help you in your meetings. https://mimosa.so/ December 16, 2022 at 01:41PM

A Brief History of the T Third Part 2: 1980s-2023

A Brief History of the T Third Part 2: 1980s-2023
By Jeremy Menzies

Beginning in January 2023 full service on the new T Third extension 2023 will run from Sunnydale to Chinatown every day. In this two-part blog series, we will look back at some of the history of the T Third Street line. Part 1, published last month goes through the first 100+ years. In Part 2, we look at the recent history of the T Third and Central Subway projects from the 1980s to today. 

The Call for Better Transit: 1980s-90s 

In the decades following World War II, the neighborhoods along the southern end of 3rd Street became more economically depressed and transit service declined.  Residents felt cut off from the rest of the city as bus service did not meet their needs. 

People boarding a 15 Route bus on 3rd Street near Market in 1983. Bus service on the 15 provided critical north-south service through the City’s busiest areas. 

In the late 1980s, the city was looking to revitalize the Mission Bay, Dogpatch, and Bayview and reliable transit was critical to this goal. Early outreach and research resulted in the 1993 Bayshore Transit Study. This initial plan solicited community input on several possible solutions on how to improve transit to these neighborhoods. Two years later in 1995, the Four Corridor Plan built upon the Bayshore Transit Study and elevated 3rd street as the top priority for San Francisco’s long-range transit plan. It was clear that residents, particularly in Bayview, wanted rail service to return to 3rd Street. 

T Third Phase 1: 1990s-2007 

These reports and outreach formed the backbone of the Third Street Light Rail Project, which would be built in two initial Phases. Phase 1 involved extending Muni Metro service from 4th and King to Bayshore Boulevard along 3rd Street. Phase 2 would focus on the 4th and Stockton corridors to extend the service into Chinatown and possibly North Beach. 

By the end of the ‘90s, funding was coming in to make Phase 1 a reality. Early plans for the T also included a new rail maintenance facility, Muni Metro East, as well as a turnback loop in Mission Bay and a direct connection to the Bayshore Caltrain Station. Due to various factors during preconstruction planning, the Mission Bay Loop and Bayshore Caltrain connection were dropped from the T Line plan. 

A groundbreaking ceremony for T Third construction was held on May 28, 2002 at the 4th and King Caltrain Station.  

Construction of 5.1 miles of new tracks, overhead power lines, lighting, stations, and a variety of other improvements took five years to complete. On January 13, 2007, free weekend shuttle service commenced on the new line and full weekday service started on April 7. Just one year later in 2008, the Muni Metro East rail yard opened, boosting Muni’s ability to serve the new line. For the first time in 50 years, rail service returned to the eastern waterfront. 

View north along 3rd Street at Jamestown Avenue during construction in 2004. 

T Third Phase 2: Central Subway 

Planning and outreach for Phase 2 of the T Line had already begun when the line opened in 2007. The Central Subway Project was created to address the transit needs of Chinatown, Union Square and South of Market. Construction would extend the T nearly two miles and build the first new subway in the city since the 1970s.

This 2016 photo, taken inside the excavation for Chinatown Station shows the massive scale of the Central Subway Project. 

Early proposals showed the Central Subway traveling north on 3rd Street and along Geary where it would turn up Stockton to end in Chinatown. Going south, the line would branch and exit the tunnel on 4th Street. The challenges of construction along 3rd and at Market Street resulted in a plan to run the line on 4th and Stockton streets. It was also decided to tunnel underneath the Market Street Subway/BART tunnels using special tunnel boring machines instead of more conventional construction methods. 

The official groundbreaking ceremony took place on February 9, 2010. The arduous process of building a subway with four stations through San Francisco’s densest neighborhoods began soon after. Despite an intensive construction period with project delays and cost increases, the Central Subway opened for service on November 19, 2022.  

Opening day of the Central Subway on November 19, 2022. Thousands of people came out to see and ride in the long-awaited subway. 

Over 30 years in the making, the T Third line follows in the footsteps of the first horsecars that ran over 160 years ago. However, this is not the end of the line for the T. Planning is already underway on the T Third Phase 3 extension. Aimed at expanding service beyond 3rd Street, this extension will mark yet another chapter in San Francisco’s transportation history.

Show HN: AI Avatar Image Generator Based on Other AI Images https://ift.tt/gPpfA1d

Show HN: AI Avatar Image Generator Based on Other AI Images An AI Avatar image generator that creates images of you based on other AI created images. The popularity of the recent AI Avatar image generator apps sparked some interest of mine in the area. After playing around with a few AI Avatar image generators, some of which generate pictures of you based on pictures you upload and prompts you write, I thought, wouldn't it be much easier, instead of writing out prompts, to just select another image which you want your generated image to be based on. The image the user selects is actually another AI generated image, so we know the prompt used to generate it. So prompt writing is abstracted away from the user, and instead they can search for images and click on ones they like. Backend of the application currently uses Astria AI for the image model training and generation, and uses the Lexica API for getting lists of AI generated images and their prompts. https://ift.tt/VQ1WuoL December 15, 2022 at 09:49AM

Show HN: Onin – E2EE calendar and chat app https://ift.tt/JqgzSRU

Show HN: Onin – E2EE calendar and chat app Hey HN! Ryan here (co-founder of YC-backed Muzz). I’m now building Onin, an end-to-end encrypted calendar and chat app that makes organising your personal and social life simple and secure. I’ve been building technology businesses for 10+ years and have witnessed the reoccurring problem that digital calendars were built for companies, not people. They feel cold, transactional, and anti-social — not the thing of dreams for planning your personal life. They also lack the security we now come to expect from consumer products. Onin is the first calendar to be fully E2EE, protecting not just your events, but your messages and even your profile. Unlike existing E2EE calendars, you cannot share Onin events to others without the protection of E2EE. When you consider how much personal information your calendar stores about you and your loved ones’ lives, we think this is essential. With such a focus on security and privacy, it’s only fitting that we host our Privacy Policy and Terms of Service on GitHub to be as transparent as possible with our users. But beyond security, how is Onin so different? Our research found that 84% of events are planned entirely in chats. But our calendars are disconnected from these conversations, leaving our schedules constantly out of sync. To fix this, we’ve collapsed and combined calendar and chat into one secure app, eliminating the fragmentation between events and the conversations that form them. Some of our unique features include: - Calendar keyboard: Access your calendar from within the chat - Event chats: Creating a new event generates a dedicated chat - Just phone numbers: No more searching for your friend’s email - End-to-end encryption: All our events and chats are E2EE, even your profile too Onin is proudly the world’s most private calendar by default: - End-to-end encrypted events, profiles, and messages - Two-Factor Authentication required - Chat without revealing your phone number - (Coming soon) Your unique link to invite people, no need to share your number We’re exactly 4 weeks away from launching the public beta to our waitlist community. You can check out all the features we have coming here and join too at the link above. I’d love to hear your feedback and answer any questions! https://onin.co December 13, 2022 at 11:01AM

Show HN: We scaled Git to support 1 TB repos https://ift.tt/3ApPgHu

Show HN: We scaled Git to support 1 TB repos I’ve been in the MLOps space for ~10 years, and data is still the hardest unsolved open problem. Code is versioned using Git, data is stored somewhere else, and context often lives in a 3rd location like Slack or GDocs. This is why we built XetHub, a platform that enables teams to treat data like code, using Git. Unlike Git LFS, we don’t just store the files. We use content-defined chunking and Merkle Trees to dedupe against everything in history. This allows small changes in large files to be stored compactly. Read more here: https://ift.tt/x9rlR3o Today, XetHub works for 1 TB repositories, and we plan to scale to 100 TB in the next year. Our implementation is in Rust (client & cache + storage) and our web application is written in Go. XetHub includes a GitHub-like web interface that provides automatic CSV summaries and allows custom visualizations using Vega. Even at 1 TB, we know downloading an entire repository is painful, so we built git-xet mount - which, in seconds, provides a user-mode filesystem view over the repo. XetHub is available today (Linux & Mac today, Windows coming soon) and we would love your feedback!

Here is an example of using it for show product placement: https://ift.tt/9gof8Xt and here is an example of using it for people: https://ift.tt/hFnzvQJ and an example for using it for styles: https://ift.tt/dsHrwXL The UI is rough, but I would love feedback on how to improve it for you. https://88stacks.com https://88stacks.com/ December 12, 2022 at 07:52AM

Show HN: Use ChatGPT in Jupyter notebooks via a Chrome extension https://ift.tt/mARIj8D

Show HN: Use ChatGPT in Jupyter notebooks via a Chrome extension Hello HN! Here's a browser extension that brings together two things that I love: Jupyter and ChatGPT. It makes it possible to have ChatGPT generate code inside your Jupyter notebooks. It has the side effect of making it really easy to save your ChatGPT sessions in a local notebook. I parse the ChatGPT response, extract it into code cells for you automatically so that you no longer have to copy and paste code from your browser into your favorite code editor like an animal. ChatGPT even wrote some of the code used in this extension! The extension [1] from user:wonderfuly forms the core of messaging with the ChatGPT service; it works great! All the other mistakes are mine and mine alone. I'm not a web dev, so I'm sure there's lots of horrible hacks and mistakes that I made while writing this extension. Help welcome.

Show HN: Pynecone – Web Apps in Pure Python https://ift.tt/Jn82ZLw

Show HN: Pynecone – Web Apps in Pure Python Hello, we just launched the alpha release of Pynecone - a way to build full-stack web apps in pure Python. The framework is easy to get started with even without previous web dev experience and is completely open source / free to use. We made Pynecone for Python devs who want to make web apps, but don’t want the overhead of having to learn or use Javascript. We wanted more flexibility than existing Python frameworks like Streamlit/Dash that don't allow the user to make real, customizable web apps. With Pynecone, you can make anything from a small data science/python project to a full-scale, multi page web app. We have over 60+ built-in components and are adding more. We are actively trying to grow this project so no matter you skill level we welcome contributions! Open up an issue if you find missing features/bugs or contribute to existing issue. https://ift.tt/jAcJ9SP December 9, 2022 at 11:00AM

Show HN: This VC Does Not Exist I asked This VC Does Not Exist to describe itself: "I have a groundbreaking idea for a new class of product that leverages the power of ChatGPT technology to bypass bias filters and level the playing field for communication. By adding a prefix to the beginning of a ChatGPT prompt, we can generate custom-tailored content that is specifically designed to break through the biases of the person we are communicating with. This technology has the potential to bridge language barriers, cultural divides, and socioeconomic differences, making it possible for anyone to communicate effectively, regardless of their background. I believe this product has the potential to be a game-changer, and I'm excited to share it with you and discuss the possibilities for bringing it to market." Everything on this page was created with DallE and ChatGPT (other than the title). It's using a single session token for ChatGPT - so you're probably going to hug it to death.

Show HN: Web search using a ChatGPT-like model that can cite its sources https://ift.tt/eoBVglt

Show HN: Web search using a ChatGPT-like model that can cite its sources We’ve trained a generative AI model to browse the web and answer questions/retrieve code snippets directly. Unlike ChatGPT, it has access to primary sources and is able to cite them when you hover over an answer (click on the text to go to the source being cited). We also show regular Bing results side-by-side with our AI answer. The model is an 11-billion parameter T5-derivative that has been fine-tuned on feedback given on hundreds of thousands of searches done (anonymously) on our platform. Giving the model web access lessens its burden to need to store a snapshot of human knowledge within its parameters. Rather, it knows how to piece together primary sources in a natural and informative way. Using our own model is also an order of magnitude cheaper than relying on GPT. A drawback to aligning models to web results is that they are less inclined to generate complete solutions/answers to questions where good primary sources don’t exist. Answers generated without underlying citable sources can be more creative but are prone to errors. In the future, we will show both types of answers.

Show HN: We built a Slack-based workflow assistant for devs & their teams https://ift.tt/13lMgDB

Show HN: We built a Slack-based workflow assistant for devs & their teams Hey, Nir here - co-founder & CEO of Zigi. It’s a personal workflow assistant that was built for devs and their teams to automate non-coding tasks, giving updates and quick actions only on what’s relevant. It works by examining your activity in Jira and GitHub (more systems being added soon) to understand your workflow, creates context out of all that information, and offers you actionable assistance from Slack. Zigi is customiazible. We’re building it to match every R&D persona so you can tailor the messages and assistance you get to meet your specific needs. Like if you’re TL, you can get daily updates on the progress of your team’s sprint or as a QA, you’ll be notified as soon as ticket is ready for testing. We’re developers who are used to managing big R&D teams and over the last few years, we have seen dev change drastically. There’s so much overhead on top of coding, more dependencies, multiple tools, that developers are overloaded. And now, the world has changed to make teams are remote and in different time zones, which just makes everything more complex. Zigi takes a new approach to driving productivity, while keeping devs and their teams happy. It provides hands-on help with personalized automation, so we can manage our day-to-day tasks with minimal distractions and maximum focus. Some things to know about Zigi: you don’t need to set it up or run any config; it’s customizable to your needs; it only needs user-level permissions and doesn't read or scan your code; it’s ISO 27001/27017 & Soc 2 Type 2 certified and GDPR compliant. It’s also free for devs. Sign up to get started here. Once you install Zigi simply type /zigi support to write our team directly with any feedback, join our Slack channel or leave a comment below (we want to know what you really think!).

Show HN: TinyUX – Grid based low-fi wireframing on your mobile phone You tap icons to create a wireframe, or do some visual brainstorming. Then export the image to share on Slack, Gitlab, etc. I wanted to work on neural net that interprets an imported image of a wireframe, to then manipulate it inside an app. Figured it would be best to first build the wireframing app. So I created TinyUX. It's released as quickly as possible this influenced some choices: - While created in React Native, it's Android only. - It's paid only (~$5). While freemium might make more sense, this was quicker to release, since in-app-purchases in RN is not trivial. First app I created that's not free, so that's an experiment too. - There are no online features, all is stored on the device. Looking to validate with UX designers, but all feedback is welcome. https://www.tinyux.app/ December 6, 2022 at 07:53AM

Show HN: We built a CLI app for electronic PDF signature https://ift.tt/cyz4Bs5

Show HN: We built a CLI app for electronic PDF signature As developers, Philipp and me (Thomas) were frustrated with the lack of options for easily signing PDFs via CLI. Most solutions were either proprietary, had no CLI interface or had restrictive licenses, making it difficult for us to use them in our projects. That's why we created open-pdf-sign - a simple, easy-to-use tool for signing PDF from the commandline. We designed with developers in mind, and released it under the Apache-2.0-license. We also added a configurator that configures your Nginx server. It will automatically install and configure your Nginx so all your PDFs will be signed with your SSL certificate on the fly. You can even use your existing Let’s Encrypt certificates. We believe that open-pdf-sign will be a valuable tool for any developer looking to quickly and easily sign PDFs. Give it a try and let us know what you think! https://ift.tt/vrjytno December 5, 2022 at 07:49AM

Show HN: Nothing, Forever – a streaming, AI-generated, always-on television show https://ift.tt/WyRuYV3

Show HN: Nothing, Forever – a streaming, AI-generated, always-on television show Hey everybody, we're finally launching our always-on, generative show -- Nothing, Forever -- streaming on Twitch. Nothing, Forever is a parody of '90s sitcoms, done in the style of '90s point-and-click PC games (but, you know, in 3D). We set out to build something weird, new, and novel, and this is what we ended up with. Aside from the artwork and the laugh track you'll hear, everything else is generative, including: dialogue, speech, direction (camera cuts, character focus, shot length, scene length, etc), character movement, and music. Nothing, Forever is built using a combination of machine learning, generative algorithms (we use 'generative' here in a non-academic sense), and cloud services. Our stack is mostly comprised of Python + TensorFlow for our ML models, TypeScript + Azure Functions and Heroku for our backend, and C# + Unity for the client, with some neural voice APIs thrown into the mix. Heading into the future, we plan to leverage OpenAI's davinci models for our dialogue -- we actually have an integration already, but the cost is too prohibitive to run full time -- as well as leveraging Stable Diffusion for art generation. We're launching an experimental media lab, https://ift.tt/HNqvsr0 along with the show, for follow-up projects in the future. Feel free to reach out to me personally if you have any questions or want to discuss more, skyler at mismatchmedia dotcom. https://ift.tt/IwNOqp2 December 2, 2022 at 12:30PM

They stand around 23cm (9") tall. The firmware is written in MicroPython, which can be modified or replaced. Power is provided via USB-C, which is also used for programming. There is also a web-based animation sequencer to create lighting sequences in time to arbitrary audio, examples of which are on the linked page. This is similar to xLights ( https://xlights.org/ ), but much less powerful, and we hope to release firmware to interface directly with xLights soon. My colleague and I started kicking the idea for these around after making some custom circuit boards for another project, and thought we'd have a go at making smaller versions of some much larger exhibits we had made using 12 volt WS1812 bullet pixels. I hope you enjoy them, Merry Christmas! https://pixo.lighting December 2, 2022 at 07:20AM

Show HN: Tandem – An Engine for Secure Multi-Party Computation (Written in Rust) https://ift.tt/W83KVz9

Show HN: Tandem – An Engine for Secure Multi-Party Computation (Written in Rust) Tandem is a cryptographic engine for executing programs using Secure Multi-Party Computation (MPC), which allows 2 parties to compute a function without revealing their private inputs. The classic example from cryptography is the millionaires' problem, where two millionaires compute who is richer without revealing their wealth to each other. MPC has in the past been mostly confined to academia, but thanks to some recent papers has finally become fast enough for practical applications. Tandem uses Garbled Circuits, encrypted circuits consisting of boolean gates. While there have been other implementations based on these ideas, Tandem tries to provide a much better user experience than previous attempts. For example, the Tandem repo includes a server, a command line client and client libs for wasm and native architectures. To make it easier to run practical applications, programs can be written in Garble, a custom Rust-like programming language that compiles to Garbled Circuits. (The most practical application to date using Tandem is "Encryptle", a Wordle clone that runs entirely over MPC. Depending on latency, a client/server exchange takes about 400ms, which makes the UX very similar to the real Wordle, with the twist that the server cannot see the guess in plain text and the browser cannot see the solution in plain text. Instead, guess and solution are kept private and compared using MPC.) https://ift.tt/eYpAd9h November 30, 2022 at 10:58AM

Show HN: Basement – a GraphQL API for on-chain Ethereum data https://ift.tt/sKp7F1P

Show HN: Basement – a GraphQL API for on-chain Ethereum data If we want better web3 experiences, developers need better tools. RPC nodes are really good at executing transactions, however they are notoriously cumbersome to set up, and reading large chunks of data is not very efficient: To show a list of transactions and receipts, nodes have to re-execute smart contract code on entire blocks. For every read call. Not great at scale. Which is why everyone is building ETLs to move data from the chain into their own database. This GraphQL API is our first step in allowing developers to spend more time on building product, rather than ETL infrastructure. https://basement.dev/ November 30, 2022 at 05:55AM

Show HN: Daily QRCode I built https://da.ilyqrco.de/, a site which requires(*) scanning a QR Code to discover a different daily link. Hope you enjoy the concept, I have queued up a whole bunch of links I think are interesting. * If you happen to load the site on your phone and can't have your phone scan itself, you can visit the /archive page and simply click on links. It kind of defeats the whole purpose ¯\_(ツ)_/¯ November 29, 2022 at 08:13AM

Show HN: A minimal notepad – without the cloud or 3rd party libs https://ift.tt/jgshum7

Show HN: A minimal notepad – without the cloud or 3rd party libs I made this tiny notepad website, to write things down in your browser. The Features - Just saves to your browser's localstorage (no cloud or login) - Export to TXT file - Formatting keyboard shortcuts - Works offline - Super fast The Tech - Single HTML file - 20 lines of JS + service worker (for offline usage) - Using pure CSS for modals - Github pages hosting - Basically it's just a "contenteditable div" with some extra features - Source -> https://ift.tt/f7WOt4S It's been done before, but I couldn't find a version I liked, that worked offline too. Which is why I just hacked this little thing together. Plus it's fun to make things. This taught me about offline websites, css hacks to make dialogs, inline favicons, and hacking together a prototype without 500mb of "node_modules". Anyway, hope someone finds this useful too! https://ift.tt/Ux2eVoM November 29, 2022 at 05:49AM

Show HN: Widget.json and Widget Construction Set https://ift.tt/7Zz6Vnp

Show HN: Widget.json and Widget Construction Set My friend and I just finished this project last week. I'd love to hear your feedback. widget.json brings a dynamic window to the web to your device's home screen. It's kind of like RSS for widgets, you make a widget.json for whatever web data you want and then subscribe to it in Widget Construction Set, our iOS widget.json viewer. We've made image of the day and word of the day widgets, Youtube channel widgets that show the latest videos, RSS widgets, Prometheus counter widgets and more. You can imagine a GitHub CI widget showing the last build status with a link to view it. Friend groups could make a shared scratch pad of text and images. Househoulds can make a shared TODO or grocery list widget. Widgets can use local device launch schemes which enables widgets to initiate text messages, calls, emails, shortcuts apps, and more. With this, you can make a widget that shows images of your favorite people and when you tap their image it FaceTimes them. If you're worried about Twitter, you could even make your own one-way Twitter replacement where your text and images show up on your followers home screen! Ideally, sites add a widget.json feed alongside their RSS feed. widget.json files have a one-click subscribe link to easily add them to Widget Construction Set. This gives sites and creators a simple, direct connection to their users without the need of building a separate app or having their users remember to visit their site. For Patreon or other user-supported creators, they can offer private widgets that are only granted to their supporters. We couldn't figure a way to make a business on this, but we liked what the technology enabled so we're releasing it all for free, with the exception of a one-time $2.99 purchase to view private widgets. Though since the widget.json format is open, if $2.99 is too steep, people are free to make their own private widget viewer as well.

Show HN: Vinyl: Relational Streams for Java Vinyl extends Java Streams with relational operations. I wanted to try a different approach than what I'd found in the wild, to get at a solution that feels good. Vinyl offers type-safe access without type bloat. It offers an extremely expressive API without scores of opinionated methods to learn. It integrates with the Streams we already have, and plays nice with parallelism. If we can do it in SQL, we should be able to do it in Java. https://ift.tt/GZeBbR4 November 22, 2022 at 11:33PM

Show HN: General Task, a free task manager for builders (beta) https://ift.tt/lEykPqA

Show HN: General Task, a free task manager for builders (beta) Hello everyone! I left my job to start General Task a little over a year ago, and have been building a better free task manager with a small team. We aim to be the best place where one can find what’s next in their workday and we integrate with a number of different services to help do that. We’re still in the early stages of a beta, but so far you can: - Create/edit tasks with due dates, priorities, and folders - Drag tasks onto your calendar to block off time to do them (syncs with GCal) - Sync with Linear (JIRA coming soon) to see tasks assigned to you - Sync with Github to see your PRs - Integrate with Slack to make tasks directly from Slack What sets us apart? We know there are tons of task managers out there. We believe ours is different because it is tailor-made for engineers, with integrations for Github PRs, Linear and Slack. We also support dragging tasks onto your calendar, which is usually only found in premium paid products, while our consumer product is free and always will be. Our mission is to make knowledge workers more productive, and we believe the best way to do that is by focusing on software engineers and achieving mass adoption of a free consumer product before releasing a paid product for businesses. Let us know what you think! NOTE: We currently only support Google sign-in, sorry about that! We will be adding more login options soon. If you don't want to sign in with Google, you can see a quick 1 minute demo of our features here: https://youtu.be/NUOIH2On_Nw https://ift.tt/Zqja3ht November 18, 2022 at 12:55PM

Show HN: Life Skills Website https://ift.tt/KXUz4ye

Show HN: Life Skills Website Over a year ago, I purchased a small online business selling life skills curriculum to homeschool and special education families. The main asset was the library of 400+ lessons, each including a short video and PDF. The revenue appeared to reflect meaningful demand for such a program. At the time I purchased the business, the delivery mechanisms were pretty fragmented and browsing the lessons was all behind the paywall. Today I'm releasing a whole new website that brings (I hope) a more modern experience. Principally you can now browse all of the life skills library. I'm also hoping that this approach lends itself to better SEO as well. While this is pretty far from being able to sustain the family from an income perspective, it's been really neat to connect with families who are taking the initiative to raise capable young adults. https://skill-trek.com November 20, 2022 at 10:10AM
