Show HN: A Python PDF Form Library https://ift.tt/H8iVNWf

Show HN: A Python PDF Form Library Hi HN! I have a project that I have been working on for three years that I’d love to show you today called PyPDForm ( https://ift.tt/vYz4puk ). It is a Python library that specializes in processing PDF forms, with the most outstanding feature being programmatically filling a PDF form by simply feeding a Python dictionary. I used to work at a startup company with Python as our backend stack. We were constantly given paper documents by our clients that we needed to generate into PDFs. We were doing it using reportlab scripts and I quickly found the process tedious and time consuming for more complex PDFs. This is where the idea of this project came from. Instead of writing lengthy and unmaintainable reportlab scripts to generate PDFs, you can just turn any paper document into a PDF form template and PyPDFForm can fill it easily. On top of the GitHub repo, here are some additional resources for this project: PyPi: https://ift.tt/zy8goG4 Docs: https://ift.tt/mwBNtkP A public speak I did about this project: https://www.youtube.com/watch?v=8t1RdAKwr9w I hope you guys find the library helpful for your own PDF generation workflow. Feel free to try it, test it, leave comments or suggestions, and open issues. And of course if you are willing, kindly give me a star on GitHub. https://ift.tt/vYz4puk February 4, 2024 at 06:55AM

Show HN: HN stories categorized by topics of interest https://ift.tt/suO98GP

Show HN: HN stories categorized by topics of interest Hi HN, TL;DR: I made a website that takes all the top stories on HN and categorizes them into one of ten topics of interest using LangChain and GPT-4. I've always liked the idea of getting a personal mix of news tailored to my interests. Hacker News is pretty close to that ideal, which is reflected in the time I spend on here every day. It's a great mix, but playing with LangChain, I got the idea for a weekend project. Roughly speaking most posts on HN fall into one of these categories: * Programming, Software & Computer Science * AI, Data Science & Analytics * Business & Entrepreneurship * Science & Research * Cybersecurity & Digital Safety * Design, User Experience & Creativity * Finance & Economics in Tech * Work Culture & Career Development * Media, Content & Communication * General & Diverse Interests Using langchain with GPT-4 Turbo (JSON mode), I sort every top submission into one of the above. Costs for using the API are currently at 15$ a month, with few optimizations. For ease of use I also added the possibility to consume the news topics via a responsive webpage, RSS and email digest (daily,weekly,monthly). https://hnto.pics/ February 3, 2024 at 03:30AM

Show HN: An open source performance monitoring tool https://ift.tt/iBt6HUh

Show HN: An open source performance monitoring tool Hey HN. We’re Jay and Vadim from Highlight.io ( https://highlight.io ). We’re building an open source [1] monitoring platform for web applications. Today we’re excited to be sharing a performance tool we’ve been working on, which helps you inspect the latency of code execution from the client to the server. As engineers at past startups, we often had to debug slow queries, poor load times, inconsistent errors, etc... While tools like Jaegar [2] helped us inspect server-side performance, we had no way to tie user events to the traces we were inspecting. In other words, although we had an idea of what API route was slow, there wasn’t much visibility into the actual bottleneck. This is where our performance product comes in: we’re rethinking a tracing/performance tool that focuses on bridging the gap between the client and server. What’s unique about our approach is that we lean heavily into creating traces from the frontend. For example, if you’re using our Next.js SDK, we automatically connect browser HTTP requests with server-side code execution, all from the perspective of a user. We find this much more powerful because you can understand what part of your frontend codebase causes a given trace to occur. There’s an example here [3]. From an instrumentation perspective, we’ve built our SDKs on-top of OTel, so you can create custom spans to expand highlight-created traces in server routes that will transparently roll up into the flame graph you see in our UI. You can also send us raw OTel traces and manually set up the client-server connection if you want. [4] Here’s an example of what a trace looks like with a database integration using our Golang GORM SDK, triggered by a frontend GraphQL query [5] [6]. In terms of how it's built, we continue to rely heavily on ClickHouse as our time-series storage engine. Given that traces require that we also query based on an ID for specific groups of spans (more akin to an OLTP db), we’ve leveraged the power of CH materialized views to make these operations efficient (described here [7]). To try it out, you can spin up the project with our self hosted docs [8] or use our cloud offering at app.highlight.io. The entire stack runs in docker via a compose file, including an OpenTelemetry collector for data ingestion. You’ll need to point your SDK to export data to it by setting the relevant OTLP endpoint configuration (ie. environment variable OTEL_EXPORTER_OTLP_LOGS_ENDPOINT [9]). Overall, we’d really appreciate feedback on what we’re building here. We’re also all ears if anyone has opinions on what they’d like to see in a product like this!

Show HN: Vibescape – Immersive Meditations for Apple Vision Pro https://ift.tt/dAKuVnl

Show HN: Vibescape – Immersive Meditations for Apple Vision Pro Hey folks, back with a new release! I'm very happy to share with you my day one immersive meditation app for Apple Vision Pro. It's called Vibescape, and it's available today! This first version features a series of meditative vignettes, shot on Spatial Video, on location in the Pacific Northwest. Dramatic Douglas Fir stands sway in a winter storm. Ripples undulate in pools of water in a 19th century quarry. Icy-ASMR in a fern covered forest. You can also set up a custom meditation timer, either silent or from a selection of deep ambient noise, and transport yourself to truly unique immersive environments. It was a lot of fun building this – from braving an ice storm to capture these vignettes for you, to developing something once again for a brand new platform. It was almost 15 years ago I took that leap when creating Polychord for iPad. Similar vibes. Hope you check it out, and let me know what you think! Lots planned for version 2, but hearing what would excite you the most would make a huge difference. https://ift.tt/tXH4OJL February 2, 2024 at 10:02PM

Show HN: Telescope – Hassle-free company research Hey HN. I recently started a company and found myself constantly doing company research for competitors, prospective customers, and outbound leads. As an engineer, I found it challenging to figure out where to get up-to-date company information as well as tedious needing to visit multiple sites often. I built Telescope to solve that problem. Under the hood, Telescope performs multiple search queries the same way I would and synthesizes the results for me. This is very much a WIP but I would love for you to try it out and let me know what you think. Over the next couple of weeks, I plan on continuing to improve Telescope and add more features.

Show HN: Privacy-first cross platform spreadsheet pipeline app https://ift.tt/4cgizHe

Show HN: Privacy-first cross platform spreadsheet pipeline app In my previous role at a small startup, I frequently developed simple scripts to assist recruiters and marketing professionals in handling data processing tasks on Excel or CSV files. These tasks were typically straightforward and repetitive, stemming from the periodic export of data. This experience sparked the idea to create a straightforward tool dedicated to such functionalities(also mobile friendly, as they occasionally need to process data on their smartphones). There are powerful tools like Power Query and Tableau, but they often prove too complex for non-technical users to navigate effectively. Additionally, ETL tools that support CSV/XLSX formats often come with a high price. That's why I build Tablesmith, an easy-to-use and free spreadsheet automation tool that empowers anyone to automate their data-related tasks with ease. Furthermore, I also include AI autofill capability, which I believe would be useful. https://tablesmith.io/ January 29, 2024 at 08:24PM

Source is available at https://ift.tt/EF2SDpm Hey y’all. My brother and I have made a framework for board games. During the pandemic we started to look at BGA but got discouraged by how old-fashioned the tools were and how cumbersome the development process was.

Our hope is anyone familiar with Typescript and CSS could code up a game without worrying about state management, persistence or networking. It’s still very much a wip, and we're rapidly adding features and games. But we’ve got our first draft of developer docs done, and we've put up a few games we've developed to showcase and test out the platform. Source for the games and framework is available on Github, and we’re excited to code more games and hopefully encourage other people to try it out.

Show HN: 12-colored visual interactive music theory for pop/rock MIDI (+Github) https://ift.tt/Hs8kp6B

Show HN: 12-colored visual interactive music theory for pop/rock MIDI (+Github) I'm sharing an early prototype of my open-source interactive book and MIDI viewer. My approach is to annotate a tonic and phrasing in each file, so that chords become visible as 3-4 color bundles after a bit of training. This radically simplifies seeing and hearing chords, so that you can rapidly browse through many arrangements and study Western harmonic/arrangement language If you don't have a touchpad, a horizontal scrolling can be done via shift+mouse wheel (generally on the web). Also, I have a second color scheme that I tried to optimized for people with color vision deficiencies. My big dream now is to have all piano rolls in DAWs support 12-coloring (in any color scheme really), so that the music can be seen as less complex, less gatekeeped and less entangled. It's not as hard as I've seen it before. Source code: https://ift.tt/75m6ixB It currently doesn't play music from Russia or Türkiye (=requires a VPN), because I rely on corsproxy.io internally which blocks access from those countries. I plan to rehost stuff on S3 soon to fix that. Also, it's more performant in Chrome than in Safari - audio clicks less. === Backstory: I quit Whatsapp in 2021 to focus full-time on studying music theory. Along that I've assembled a list of resources to see the frontier: https://ift.tt/zAq910B My biggest inspiration is Hooktheory - an interactive book that teaches how melody and chords interact in Western pop music. After it I wanted to study how the rest of the arrangement works - what the bass line is doing, how is melody doubled, what chromatic chords are possible, are there any functional pre-dominants and dominants in mixolydian or dorian etc. I wanted to focus on music for which the complete arrangement is clean and available. This is early chiptune (NES/Genesis) OSTs and MIDI arrangements (primarily created in 1990s). As I plugged MIDIs into my front-end, I discovered that the harmonic analysis - the cornerstone of studying Western harmony - can be done by eyes in real-time. That is, if you color the notes consistently, the chords start to stare at you, sharply and memorably. I'm intrigued by latest shifts towards corpus studies in music theory and I'm generally happy that nowadays the research is not just about classical music anymore. At least in the West. https://rawl.rocks/ January 28, 2024 at 07:07PM

Show HN: Object-Oriented HTML – Proposal for new powerful features in HTML https://ift.tt/TKJXmia

Show HN: Object-Oriented HTML – Proposal for new powerful features in HTML Hey all, I'm a big fan of the HTML-first + Progressive Enhancement approach to UI development! For a background: 1. I like to be able to write HTML by default and progressively add JavaScript (and, in the same way, progressively involve tooling) instead of go ahead of the problem by going the other way around! 2. Also turns out that UIs are more resilient when built on the same principles: - given how browsers process web pages: HTML initially, then JavaScript eventually; with the bulk of the page being best done at the initial phase - and given how, on a more general note, performance is a function of browsers doing the heavy lifting But it turns out that as compelling as it is to move more to HTML, there isn't as much you can do in HTML as you'd like to! In my experience, four specific limitations have felt like a deal breaker: 1: How Do You Do Reactivity? 2: How Do You Make Components? 3: How Do You Re-Use Components? 4: How Do You Pass Data/Props? I've since committed to exploring the answers to those questions, and my life's work here is what I propose as Object-Oriented HTML - a set of HTML/DOM-level features that let us write dynamic and object-oriented markup! (Full explainer is here: https://ift.tt/atyIe8W... ) I am hoping that this moves us forward on the HTML-first + Progressive Enhancement paradigm! But as with everything on the web, it's all about your thoughts!!! https://ift.tt/ejWuMgq January 26, 2024 at 12:40AM

Show HN: Startup funding simulator https://ift.tt/fXSMdZi

Show HN: Startup funding simulator Hi HN We built a tool to help founders understand how modern fundraising (with safes) works, and how much dilution you can expect when raising money. The project is open-source. The code is a mess right now, but it'll get better I promise. You can also help with that. We didn't build this to make money. We genuinely did it because we were looking for it, and couldn't find it. We're in fact in the process of fundraising for a company, and at first glance the process looks simple. Just an excel sheet will do! But then the more we dug into it and tried different simulators, the more we realized that it's more complex than it looks. We even signed up to Pulley, Carta and others just to run simulations. But they're a bit confusing. TL;DR: Understanding modern startup funding and knowing how much dilution you'll face is hard. We built a tool that'll hopefully help with that. You can add Post-money Safes, priced rounds and issue options to employees, and you can see how that affects your ownership at every step. You can also simulate an Exit scenario and see how much money you'll be left with. --- Some examples of complex stuff: - There are many different types of safes. They all convert at the first priced round, but in different ways. Some are through discount, some are uncapped, some have a fixed valuation cap, and some have both a discount and a valuation cap. - All safes (before first priced round) convert at the same time. They don't dilute each other, which is what happens in the rest of fundraising. - Investors often require you to set aside some options. This one is particularily nasty. Basically, if an investor expects you to set aside 10% as options, and expects to get 10% equity, that's what should appear in the subsequent cap table. However, calculating the options is difficult, and is often a circular calculation (even Kirsty Nathoo from YC says it's complex and avoids showing the calculation in the Safe video "Understanding SAFEs and Priced Equity Rounds") - Safes and priced rounds can have pro-rata, but don't always exercise it - Pro-ratas of safes are taken from the priced round money, so you'd expect the safe holder's equity to remain the same if they exercise it. BUT ... it gets diluted by the new options issued. - Safes can have an MFN provision, which defers the valuation discussion/calculation until the moment the priced round is about to close. With a mix of discounts, uncapped and valuation caps, it gets tricky to know which deal is "better". - ... Assumptions and limitations: - Only post-money safes and priced rounds. - No down rounds. There's a bit more complexity around liquidation preferences and anti-dilution rights - we don't support that now. It only matters if you're simulating a "bad" situation. But come on, it's a simulator — Be optimistic. - No pro-rata caps. We might add that soon, to fully support the YC standard deal. But for now, if an investor gets a pro-rata, they can exercise either all of it (keeping their original ownership) or none. - Safes' pro-ratas disappear after the first priced round. (I think this is what happens normally?) - Remaining available options get redistributed evenly at exit. - The round is the investor. For the sake of simplicity, consider "Series A" as the combination of all series A investors into one, super-investor. Let us know what you think! https://ift.tt/UzPjYMX January 24, 2024 at 11:41PM

Show HN: Finagg – free and nearly unlimited financial data https://ift.tt/1bvlQaP

Show HN: Finagg – free and nearly unlimited financial data finagg is a Python package and CLI that enables you to aggregate and update free financial data from a handful of high quality data sources all within your own SQL database. Here're some quick facts about it: - Implements nearly all of the BEA API, FRED API, and SEC EDGAR APIs (all of which have free and nearly unlimited data access) - Only focused on macrodata (no intraday data support) - Provides methods for transforming data from these APIs into normalized features that're readily useable for analysis, strategy development, and AI/ML - The most popular methods include getting historical price earnings ratios, getting historical price earnings ratios normalized across industries, and sorting companies by their industry-normalized price earnings ratios - Python >= 3.10 only (you should upgrade anyways if you haven't ;) I'm looking for feedback on the overall package and CLI designs. Also, I'd appreciate any recommendations for implementing other financial data sources that're free with no daily API limits. Cheers! https://ift.tt/GI5Es1f January 22, 2024 at 08:46AM

Show HN: Chai - remote PDF and Hex Viewer service accessible via remote browser https://ift.tt/P75lcd0

Show HN: Chai - remote PDF and Hex Viewer service accessible via remote browser I'm really happy with this. It doesn't provide the "best" PDF support (it converts to images, page by page) -- but it does support a bunch of other documen formats supported by the union of LibreOffice, Pandoc and MuPDF -- and it was hella fun to write and get working: a mix of bash scripting glue, nodejs servering, and dependency installation. Next up in the todo for Chai is getting it working on Windows (which will basically involve finding the right dependencies and maybe branching within the bash glue for their different paths from the Windows dimensions haha! :)). I was particularly proud of the hex viewer part. I just felt it was not complete without really being able to see the byte by byte playout of a file. Obviously there are some file size limitations (but the hex viewer is streaming, so should work for any size the underlying system can handle), and therefore optimally efficient. Oh, and it also should handle archives just fine, as in, you can open {zip,tar.gz,... etc ...} archives and inspect them "file viewer" style. Somehow I just felt this kind of capability (remote viewing files, from a safe and secure distance) was absolutely necessary for a remote browser. I often think of these things like a "glovebox"^0 0: https://ift.tt/draSXp0 specifically designed for handling hazardous materials, including biological, chemical, or radioactive substances. Gloveboxes provide a sealed environment where researchers or technicians can manipulate hazardous substances safely https://ift.tt/mrL5enw January 21, 2024 at 10:13AM

Show HN: I built presently.live for better weekend planning and insights https://ift.tt/UoJncT1

Show HN: I built presently.live for better weekend planning and insights Hi HN , my partner and I were looking for easier answers to our weekend planning ritual, such as: - When is our next free weekend? - What weekend activities have we got planned? - How busy/available are we to travel / host? Especially at the start of each year, when we're trying to plan flights and/or commit to hosting friends & family visits, I struggled to find a usable overview of multiple months that wasn't cluttered with weekdays. Our social events are overwhelmingly centered around weekends and we wanted a view of the year ahead that reflected that. How about just a line of 52 boxes, one per weekend ahead, shaded differently whether it was free or maybe busy or definitely busy? That was the initial sketch on a napkin that lead to a first proof of concept script that I ran locally. Now, it's a webapp* that reads from our calendars (Google only for now, sorry) to visually summarise weekends - all with readonly access. I've since added some calendar-write features from there ("pro" version, completely free) as our lives become busier with a dog, and parenthood more recently. Features like event templates, summarising events by hashtags, flagging draft/unconfirmed events etc. We've been using it to scratch our own planning itches for some years now already, and I'm sharing here now in case it can be useful for others. Even better if you have any feedback. What / how have you hacked to get clearer and direct insights into your time? I think time management and calendars have been lacking a UX overhaul for a long long time so it's a space I'm passionate about tinkering within. *stack is Nuxt 3, backed by Supabase, hosted on Cloudflare Pages. https://presently.live/ January 21, 2024 at 02:58AM

Show HN: We built a multimodal AI interviewer for mock system design interviews https://ift.tt/XsWKlni

Show HN: We built a multimodal AI interviewer for mock system design interviews Hey HN! We’re Jared, Shreyas, and Varun the creators of TechInterviewer. We’re building a product for software engineers to go through an entirely simulated systems design interview. Our AI interviewer, Steve, gives you a prompt and you talk out loud and draw on a whiteboard while Steve guides you through the interview and gives real-time feedback. Check out our demo: https://ift.tt/40fwNWm Every software engineer today has to prepare for systems design interviews and have two awful options: pay hundreds of dollars for a single session with a FAANG engineer or follow silently alongside a YouTube playlist. Because there is no instant feedback while practicing, engineers often learn about their most important knowledge gaps during the course of the interview loop. Jared and Shreyas are both senior engineers who have spent 1000s of hours preparing for and administering systems design interviews. Shreyas was an early engineer at Deepgram and spent many years tracking developments in the TTS (text to speech) space. He realized that voice interviews had potential to change the candidate experience when he starting using chatGPT to prepare for interviewing founding engineer candidates at his startup. We’re hoping that having easy access to interview feedback will level the playing field of software engineers at different skill levels. We’re really excited to share this with you all and we’d love any thoughts, feedback, and comments https://ift.tt/uS9La3Z January 19, 2024 at 07:59PM

Show HN: Transitive, an open-source framework for full-stack robotic software https://ift.tt/rnmfF6I

Show HN: Transitive, an open-source framework for full-stack robotic software After three years in development, I'm thrilled to share Transitive: an open-source framework for full-stack robotic software ( https://ift.tt/2yzOd7T ). The Transitive framework makes it easy to build robot cloud portals. Even given all the great open-source tools for web development and device management, building such cloud portals for robots is still not an easy task. There are several reasons for this, but a big one is that robots are different from regular servers, despite many people attempting to tread them as such. They go offline a lot, have limited network bandwidth, and each robot in a fleet may run a different version of software and require a different configuration. Robots also generate a lot of data, some of which needs to be synced in real-time with cloud and web front-ends for processing and visualization, some of which recorded, and some discarded. In addition robots roam insecure areas and are connected over networks outside of the control of the startup, hence requiring tight authentication and authorization. Transitive solves many of these issues. It provides a reliable, real-time data synchronization protocol that operates on top of MQTT, called MQTTSync. MQTTSync seamlessly synchronizes stateful data between robot, cloud, and web, instead of just passing messages. It provides the notion of full-stack packages that implement encapsulation and versioning of software components for all three systems (robot, cloud, and web) and uses MQTTSync's name-spaced data model to reliably communicate and operate, even when different robots run different versions of the package. The robot and cloud components are run in sandboxes to isolate them from the rest of the system, and the web components can be embedded in any web page including existing robot cloud portals. And of course, all this is secured, using SSL for transport-level security, client certificates and JSON Web Tokens for authentication, and authorization based on MQTT topics. Taken together this lays a solid foundation for building new full-stack capabilities with ease. Note that Transitive is not a replacement for ROS, and in fact many of our capabilities run ROS nodes on the robot. Neither is Transitive a fleet management system. It just makes it easy for you to build your own! To learn more about our first release of the self-hosted version, please see the linked blog post. If you just want to try it out quickly please go to https://ift.tt/grEFXTt to create a free account, which will also give you some starting credit for try out any of our premium capabilities, such as webrtc-based video streaming, our web-terminal, or file-sync ("Dropbox for robots"). I'll be watching this thread for responses, or you can use the contact info at the bottom of the blog post to get in touch.

Show HN: I made a visual editor for GitHub Actions workflows https://ift.tt/GivCLAF

Show HN: I made a visual editor for GitHub Actions workflows Hey there, I have always been a fan of GitHub Actions workflows but for some reason never liked YAML files as being the assigned file format for non-linear workflows. While YAMLs are great as configuration files, they can be quite tedious when it comes to creating, reviewing, and maintaining workflows. To solve this, I created a visual node system that makes the workflow creation and maintenance process more efficient and intuitive. It's a straightforward node engine with an UI editor. Examples for such a node graph are here: https://ift.tt/YCxmlWz... and here: https://ift.tt/zP4hwQ7... . For clarification, they are directly executed on GitHub runners. These graphs took me minutes to build in order to focus on my actual project. The next time you create a new repo, give it a try. Love to hear your thoughts! Thanks! https://ift.tt/jXJOTaA January 17, 2024 at 12:50AM

Show HN: C port of the (non-super) Star Trek game, incl. WASM for browser/phone https://ift.tt/8Kv9pfL

Show HN: C port of the (non-super) Star Trek game, incl. WASM for browser/phone Hi HN, I've decided to port the original (non-super) Star Trek game to C since I wanted to try playing the original but wasn't able to find a lot of sources that run on modern machines. Therefore I based this port on Michael Birken's 2008 C# port. This is in contrast to the Super Star Trek game which was far more popular and has a number of sources available on the web. I took some hamfisted measures to allow the Web Assembly version of the game to be played on mobile as well, it's not very pretty but it kind of works. You can tap into the terminal to open your phone keyboard, then the terminal should be visible in the top half while the keyboard can stay open in the lower half. The tips section on the page has some further hints. The port itself is quite crude but I made sure that it is ANSI C89 compliant, because I wanted the game to be able to run on just about anything. For the best effect, I recommend playing the game using the aptly named cool-retro-term. https://ift.tt/9RqWpzn This is the best way to play short of hooking up your needle printer as a faux teletype terminal. https://ift.tt/ygHWLn0 January 14, 2024 at 01:25AM

Show HN: I built yet another ChatGPT Chrome extension https://ift.tt/KY7nQhb

Show HN: I built yet another ChatGPT Chrome extension Hey HN, I’m here to introduce you my first of hopefully-many-projects-to-come this year: ReadPal.ai, a chrome extension that let’s you chat with ANY web pages while browsing. Let’s first address the elephant in the room: there are tons of chrome extensions of sorts out there…Why did I choose to work on this? Over the years, I’ve had many projects started that never crossed the finishing line; and also many ideas that’s dauntingly ambitious that I never even started. So I chose this project, in the hope that its moderate size & scope can help me finally exercise the build→ship muscle. And I must say, it has served its purpose. I thought it would just be a weekend project, however, end up dragging it for months…With the pressure of the year-end and the free time in the holiday season, I finally got to the ship phase! During the process of building, testing, and beta testing, I came across two revelations about the product: - Having AI side by side with access to the same information as you is very helpful! It's not just about summarizing long research papers, but even simple day-to-day activities can benefit from it. e.g. asking “is this miso good for making ramen?” on a miso product page on amazon, etc. - Despite a lot of similar extensions, there is still room for differentiation! The average user who isn’t intentionally following the developments in the AI field, can benefit from a tool that simplifies the complexity of various models & prompting techniques, and focuses on providing a user experience that seamlessly integrates with their workflows. There is still a long way to go in terms of the second point. Your feedback would be very helpful with that! Thank you!! https://readpal.ai January 11, 2024 at 09:03PM

Show HN: I built an affordable alternative to Spotify and YouTube Music Premium https://ift.tt/mCR4pid

Show HN: I built an affordable alternative to Spotify and YouTube Music Premium Hey guys, I had to cancel my spotify premium subscription which was a terrible thing once I like to listen music in loop while coding or at the gym. So I decided to code myself something cool to solve my own problem that makes possible listen music in loop and without ads. I took a night off and started coding something.. so that's how I built Youtube Music Loop. I know many ppl like to listen music but not everyone can afford to pay, so it's a lite affordable version of spotify and youtube premium, where you can: - Keep listen music without ads. - Synch your playlist through all your devices. - Listen music in loops and without ads. - Search for your fav music or just copy and past the link of youtube song (when search api doesn't reach its limit). - Get it as pwa / app in your phone home screen. - Works on pc and laptops, tablets and mobile devices. - Easy and simple to use, no fluffy stuff. It's an affordable option and you pay once and use it forever, which is more than half of youtube and spotify premium subscription price. You check it here: https://ift.tt/zv0Z9YD Let me know what you think and improvements you like to see, I have made many improvements as you can see here and here. -Fausto https://ift.tt/zv0Z9YD January 11, 2024 at 11:52PM

Show HN: Peer-to-peer mini r/place with Proof of Work Hi HN, This is a site where users can submit content and the shortest SHA256 value of nonce+content among them will make the site display the content. Very basic, without a blockchain. It's a static site with WebRTC and peer-to-peer. Why? I wanted r/place (Reddit canvas where users collaborate on a pixel grid), but with proof of work. This is my progress so far. It's a WebRTC app with peer to peer connectivity that forwards the best hashed values to other users, which verify them, display them and pass them on. There are many many improvements to be done (especially I should probably use something like libp2p-gossipsub, otherwise scale is probably an issue) and more ideas to be implemented, and I'm sure there are bugs. But I didn't find any similar projects yet (except blockchains of course). Hope you like it! https://ift.tt/IWRo4VX January 10, 2024 at 06:15AM

Show HN: Asymptotic Growth Order Calculator https://ift.tt/i9yz1F2

Show HN: Asymptotic Growth Order Calculator I'm an undergraduate student and for my math honors thesis I'm studying asymptotic growth orders, the kind you usually see written in "big-Theta" notation to describe an algorithm's time/memory usage. The most interesting part was studying how to compute the growth order of the sequence of partial sums of a given sequence - that is, the growth order of (a_1 + ... + a_n), in terms of the growth order of (a_n). So I thought I would make a little web calculator for playing around with this. Enjoy! :-) Some things to try: 1. The sums of the harmonic sequence (1/n) diverge, but can you find a faster-decaying sequence that also has diverging sums? 2. Can you make the growth order log(log(log(n))) using only one register? 3. What happens when you apply Σ⅟ΣΣΣ (applied from right to left) to any growth order, and why? https://ift.tt/M1Gg79i January 9, 2024 at 11:22PM

Show HN: Auto Wiki – Turn your codebase into a Wiki https://ift.tt/R8I9gMi

Show HN: Auto Wiki – Turn your codebase into a Wiki Hi HN! I’m Omar from Mutable.ai. We want to introduce Auto Wiki ( https://ift.tt/VEBdKTr ), which lets you generate a Wiki-style website to document your codebase. Citations link to code, with clickable references to each line of code being discussed. Here are some examples of popular projects: React: https://ift.tt/maHj1X9 Ollama https://ift.tt/Y1RyWHV D3: https://ift.tt/gz65MRB Terraform: https://ift.tt/vlxkfcT Bitcoin: https://ift.tt/vY0Mi67 Mastodon: https://ift.tt/bZcpBhu Auto Wiki makes it easy to see at a high level what a codebase is doing and how the work is divided. In some cases we’ve identified entire obsolete sections of codebases by seeing a section for code that was no longer important. Auto Wiki relies on our citations system which cuts back on hallucinations. The citations link to a precise reference or definition which means the wiki generation is grounded on the basis of the code being cited rather than free form generation. We’ve run Auto Wiki on the most popular 1,000 repos on GitHub. If you want us to generate a wiki of a public repo for you, just comment in this thread! The wikis take time to generate as we are still ramping up our capacity, but I’ll reply that we’ve launched the process and then come back with a link to your wiki when it’s ready. For private repos, you can use our app ( https://app.mutable.ai ) to generate wikis. We also offer private deployments with our own model for enterprise customers; you can ping us at info@mutable.ai. Anyone that already has access to a repo through GitHub will be able to view the wiki, only the person generating the wikis needs to pay to create them. Pricing starts at $4 and ramps up by $2 increments depending on how large your repo is. In an upcoming version of Auto Wiki, we’ll include other sources of information relevant to your code and generate architectural diagrams. Please check out Auto Wiki and let us know your thoughts! Thank you! https://wiki.mutable.ai January 8, 2024 at 11:56PM

Show HN: Filter and Monitor Hacker News Based on Your Interests I was overwhelmed by the pace of AI news and papers coming out, so I built an automated HN news monitoring service that delivers relvant news straight to my inbox or RSS feed. It uses LLMs to extract, summarize, and classify the front page articles and analyzes the different perspectives in the comments. No more FOMO :) https://ift.tt/7bOMeuh January 6, 2024 at 11:16PM

Show HN: Hashmap.me – Simple HTTP-Based Data Storage and Retrieval https://ift.tt/orTc4Nm

Show HN: Hashmap.me – Simple HTTP-Based Data Storage and Retrieval I'm excited to share Hashmap.me, a small tool I've built to simplify data storage and retrieval. It's a straightforward service that allows developers to store data records via HTTP requests and retrieve them easily, all without the hassle of setting up and managing a database. Initially I built this because I was tired of creating a database to prototype my own projects, I just wanted to persist my in memory cache between restarts early on. Each hashmap you create corresponds to its own collection in MongoDB. Perfect for small projects, quick prototypes, or learning purposes. I'd love to get your feedback and hear your thoughts! Check it out here: https://hashmap.me Thanks for taking a look! https://hashmap.me January 6, 2024 at 06:42AM

Show HN: Fitlock – Block apps until you reach your daily fitness/health goals https://ift.tt/h9E0e17

Show HN: Fitlock – Block apps until you reach your daily fitness/health goals Introducing Fitlock, the privacy-focused app designed to empower users in curbing screen time and enhancing fitness through the utilisation of Apple Health and Screen Time features. Fitlock's innovative approach involves blocking apps and websites until users achieve their daily health and fitness objectives. Here's how Fitlock operates: users can establish a personalised schedule to block specific apps at chosen times of the day, adjusting the strictness level of the block to suit their preferences. Once the user's schedule is active, the blocked apps remain inaccessible until they successfully meet their health and fitness goals. For instance, a user might set up a schedule to restrict social media apps daily, unlocking them only for 30 minutes each time they reach 2000 steps within the specified timeframe. Beyond its core functionality, Fitlock boasts additional features like progress tracking over time and a range of strictness levels to cater to diverse user preferences. It's worth noting that Fitlock is currently exclusive to iOS, but stay tuned as there are plans to develop an Android version in the near future. I'd love to hear your questions/feedback. https://fitlock.io/ January 6, 2024 at 04:12AM

Show HN: Hook – a simple graphical C/C++ runtime editor https://ift.tt/AhJk7Bz

Show HN: Hook – a simple graphical C/C++ runtime editor While helping one of my students create and iterate on a game in C using raylib, I realized there was quite a lot of time spent on experimenting with level design and colors, how the player moves, gravity, etc. and a lot of time was wasted making a change, exiting the game, recompiling, running the game, deciding his change wasn't right, and going through the whole cycle over and over. I could tell it was demotivating, and this process was creating a barrier that prevented him from experimenting to his heart's content. I started this project to solve this problem by giving a simple gui to a few core features of lldb through the lldb api. Experimenting with changing colors, where blocks in the level go, how tall the player is, gravity is all now just a simple toggle or text field edit. The variables are modifiable while the program is running. The project is still in its early stages, and so far only targets macOS. https://ift.tt/I3f0APb January 2, 2024 at 06:45AM

Show HN: Cassette, a Personal Programming Language https://ift.tt/3XnF6vJ

Show HN: Cassette, a Personal Programming Language I made this simple language over the past year, and it's time for me to say it's "done" (for now) and focus on other projects. I've struggled to answer the question "what is this language for?" other than "it's just for me" — and that's probably good enough. But I also wanted to make something "complete" that others could use if they wanted to. Writing my own language was an incredibly rewarding experience, and I'd recommend everyone trying it. Let me know if you have any questions or feedback, and please share your own experience if you've also made a language. https://ift.tt/yDvOz2J January 1, 2024 at 03:31AM
