Show HN: Merit – Career mentorship for tech workers Hello Hacker News! I built a free service where you can schedule 1:1 video mentorship calls with senior ICs and managers in software engineering, product management, and design. The goal is to remove barriers to building a professional network that can help you grow your career like building skills and getting referrals. Right now we’re limited to folks living or working in the US or Canada, but we’re working on expanding beyond that one day. Without logging in, you can browse mentors here: https://ift.tt/9HbXZkr Between tech layoffs, hybrid work, and an uncertain industry outlook, I hope this can be a useful resource for you or someone you know, especially if you do not have a large professional network. I would love to hear your feedback! https://ift.tt/rFCa7nD January 31, 2023 at 02:27AM
Show HN: Semantic Bible Search using OpenAI's latest embedding model Hey HN! My brothers and I have worked on this for the last 2 weeks.

We'd like to see what you think and appreciate any feedback! https://ift.tt/gvNyaBl January 30, 2023 at 10:56PM
Show HN: Asdf Clone Written in Rust I think that asdf (https://asdf-vm.com) was a great idea for a project. It helps consolidate installing and running different programming languages into a similar UX. It also is built with a plugin interface that makes it easy to build support for new languages. However it is so slow. I was just testing `node -v` and it was taking ~900ms. That kind of overhead is completely unusable. My shell prompt uses runtimes inside of it for various things so this effectively makes every command take multiple seconds to complete. So I rebuilt it in Rust but using the same plugin ecosystem so it should be a drop-in replacement. I also added a couple of features that I wanted from asdf (aliases and fuzzy-matching). Let me know what you think! Just know that people have only been using this for a few days so if you see any bugs, they're likely not big hairy issues, just overlooked edge-cases and will be fixed soon. https://ift.tt/pmwY5nx January 30, 2023 at 10:52PM

Show HN: Peer Review Beta – GitHub plus StackExchange for Scholarly Publishing Hi HN, I've had the idea for a scholarly publishing site that could crowdsource the work of the journals using concepts borrowed from Github and StackExchange and recombined for years. I finally got enough runway to take about 6 months off of work to build it. This is the result. It's still in beta, but the core MVP features - review, reputation, responses - are all there. I'm sure there are as yet to be found bugs, because I'm on my own and I've always been terrible at testing my own stuff. Right now it's best treated as non-archival pre-prints with review. I'm starting my next full time role on Monday, so I'll be carrying it forward as a side project. I'm going to continue working on it, albeit more slowly and on nights and weekends. It's open source and with an open roadmap, and I would welcome collaborators. I would love and appreciate any thoughts and feedback! https://peer-review.io January 28, 2023 at 01:18AM
Show HN: Insults as a Service This is just a joke, but it might make some of you smile. In seventh grade my English teacher had our class write Shakespearean insults and then battle each other in a Bracket of Dis.

Show HN: Chrome extension to close Zoom tabs after launching desktop app Hi HN! I use the desktop versions of Zoom, Notion, and Asana, so at the end of the day, I have a ton of Chrome tabs left over from these services launching their apps. I threw together a little extension to clean these tabs up. Do folks tend to use the browser versions of these apps?

Show HN: A.I. Runner Several months ago I released a pay version of my software A.I. Runner but quickly pulled it due to some technical issues. I also didn't care for the architecture (a .net form app running a python server and communicating over a socket). I reworked the application and have relaunched it today. It is written in pure python and has a number of features that the previous version lacked. Current features are txt2img, img2img, inpaint, outpaint, an image gallery, an editable huggingface model db, sprite mode (for easy pixel sprite creation - the whole reason I started the app in the first place) an infinite canvas for outpainting and more. I have released it as a free application and would appreciate any feedback. I recommend installing with the itch.io launcher as this will allow you to easily check for updates. https://ift.tt/2YFsW81 January 27, 2023 at 06:01AM
Show HN: Peak Gaming – Tournament platform for everyday gamers Hey HN community! I'm super excited to shoutout Peak on HN as its a project a buddy and I have worked on tirelessly for the past year or so. Peak is a service that hosts free, cloud based tournaments for everyday gamers with real prizes and skill based matchmaking. Our main offering is our "Passive Tournament" system which allows you to have your regular public matches automatically tracked without ever having to manually enter your scores. Basically, you play just like normal, and Peak keeps score. At Peak, our focus is to make competitive gaming accessible and enjoyable to all. We’re democratizing gaming to bring the same competitive incentives formerly only available to pro players to the everyday gamer. The driving force behind developing Peak was the current state of esports and competitive play for the regular gamer. Put simply, it's too complicated and the barrier to entry can be super annoying. Any criticism/thoughts would be incredibly appreciated since we are trying to iterate as best as possible to turn this service into a thriving community of gamers. Feel free to make an account too and check out some tourneys :) https://ift.tt/NkTJSqo January 27, 2023 at 01:40AM

Show HN: I made a site that automatically unsubscribes you from unread emails Hi Guys, I'm Spencer and recently built AutoUnsubscribe to keep on top of my email subscriptions. The basic idea is: Automatically unsubscribe from unwanted emails that you never open, so you can focus on the emails that matter, saving yourself time and effort. I find overtime I accumulate hundreds of email subscriptions accidentally, especially when I ran an ecommerce business where our emails seemed to end up on all our suppliers, and their suppliers mailing lists. Some people stay on top of unsubscribing easily, however it's something I've always struggled with, especially having ADHD. I wanted a way to stop my inboxes getting out of control without me having to do anything so I built this app. An added bonus is it helps you unsubscribe from subscriptions you were on the fence about unsubscribing too, as it points out you have not even opened them. It also warns you before unsubscribing and gives you a chance to whitelist a subscription, to make sure you keep the ones you care about. I realised a lot of people would get the most value out of AutoUnsubscribe very quickly, so I wanted to provide an option for them, as opposed to just subscribing for a month and then cancelling. As a result the base pricing is $5 for seven days, which will let you basically clean out your inbox. I built out the app using Ruby on Rails, to avoid getting lost in the complexity of Javascript frameworks, as an individual developer/designer I think it was the right choice. The app is privacy focused, I will never share or sell your data. It's also why it is a paid app. I know free unsubscribe apps in the past have monetized by selling user data. You can see the site here: https://ift.tt/VUM3dCy https://ift.tt/Wgw4Ry7 January 25, 2023 at 09:15AM

Show HN: A tool to design and run user state machines Hi everyone, I’m Joe, CTO at Dopt. We’re building a tool that lets you design user state machines with an SDK so that you can run them in your product. We offer a React SDK that lets you create instances of those machines for any user of your product and exposes methods for transitioning the state of the user—effectively moving them through the machine. Dopt then acts as a persistence layer for the users’ machine state. We call our machines “flows”. Dopt lets you send in data about your users (identify calls/properties) and lets non-devs define rules based on that data for which users should enter the flows. Non-devs can also update content and other custom properties that can be referenced via the SDK. For example, with Dopt’s SDK you can build: - a multi-step, interactive product walkthrough that helps users learn how to use a product by using it ( https://ift.tt/ynrJoSE ) -a getting started checklist that helps a team get setup and activated ( https://ift.tt/KgnLIz1 ) You can see a short 4 minute demo of how Dopt at https://www.youtube.com/watch?v=1gRvAp6Cnls We make iteration on your state modeling easy with flow versioning, and we even handle migrating your users between versions on the fly. Dopt’s UI lets everyone easily track how users move through your flows and provides controls for enabling/disabling or resetting them. We’ll work right alongside your analytics and experimentation tools. We started Dopt because we’ve seen the teams building onboarding/education flows struggle with a similar set of issues that Dopt sets out to solve: - Homegrown onboarding is time-consuming to maintain (and it changes a lot!). The logic of the flows is complex and opaque to non-developers and devs are forced to be in the loop for every small copy, targeting, and logic change. - The customer and user data needed to show people relevant experiences lives in multiple places and is hard to build interactive experiences with (e.g. what’s their use case, what plan they’re on, what they’ve done in the product, what other teammates have done in the product, etc…). - Persisting and migrating user flow state is hard. The existing tools aimed at helping people put onboarding into their products frankly suck. They’re not built for developers, only offer boilerplate components, and have brittle integration points that are hard to troubleshoot. They end up producing mostly low-quality tooltip tours. We’re in a closed beta period right now but are looking to find more people building product onboarding that are willing to give Dopt a spin. We’re not charging for Dopt during our beta period and are just asking for feedback to help us learn how to make Dopt better. We’ll eventually start charging later this year (by monthly tracked users) when we go fully self-service but are planning on having a “free in-perpetuity” tier for small use cases to make it easy to evaluate whether Dopt’s valuable. We won’t pull the rug out from anyone who’s built with us during the closed beta. You can signup for our waitlist on dopt.com or drop us a note at info@dopt.com. If you mention HN we’ll skip you to the head of the line and get you product access. We’d love any feedback on the site, docs, and examples too! https://www.dopt.com/ January 26, 2023 at 04:37AM

Show HN: LowEndInsight – a “bus-factor” risk analysis tool What began as a pet-project a few years back, an a start to learning functional programming with Elixir, turned into a bit of a research effort for CS students. I'd asked them what info could they glean from a git repository, specifically about the risks associated with using it (or becoming dependent on it). The focus quickly arrived at "bus factor" - what happens when the main developer moves on. From there we started thinking about other metrics and a couple stood out - mainly the distribution of contributions, and the obvious commit currency time. The initial research was focused on library packages from the main ecosystems - e.g., Javascript's NPM and Python's PyPI. We quickly found that to be a massive challenge - at the time neither required packages to provide a valid URL pointing to their source code. This itself was an indicator of something. Once the students moved on I continued to think about and would occasionally get asked about the tool. So I picked it back up and slapped an API on it and exposed it via HTTPS POST and GETs. I am generally looking for feedback. Probably more about the issues associated with dependence on Open Source libraries - the risks derived as software atrophy happens. But what are your ideas about the metainformation that is sitting in a software project's source history. I've considered doing some ML-y stuff with the commit history, but haven't really found the right things there yet. Here are some links to the details: * Library: https://ift.tt/FJT7fVO * API: https://ift.tt/s57Nwvu... * API Source: https://ift.tt/EzbeGQ5 * CLI: https://ift.tt/ogQbHpZ * CLI Source: https://ift.tt/LI32S4p * Demo - GitHub Trending Repos: https://ift.tt/LB5camM I've capped the number of requests at RapidAPI, but if you really think the tool is useful I can issue you freer, more unlimited access by request. Let me have it HN. And thanks in advance. https://ift.tt/Fghi3aH January 24, 2023 at 08:19PM
Show HN: Fileport – Teleport Your Files Hello HN, Fileport is an online service that provides the fastest way to send files over the internet. Typically, email providers have file size restrictions and online cloud storage can be cumbersome to use. Fileport is the simplest way of transferring large files from point A to B. Intended for creative individuals like artists, video/audio editors, photographers showcasing their work or anyone whose work depends on exchanging large files. Fileport is capable of “streaming” files to the recipient (or multiple recipients) as you upload them. You can upload multiple files or folders which can be downloaded in a compressed format, even while uploading. Files are automatically checksummed for integrity during the upload process. There is a subscription available for users that require more features, like Photobooks. Photobooks are online photo & video albums that provide an ultra fast and clean web interface with all original files available for download. Files up to 2 GB can be uploaded by anyone without the need of an account. https://fileport.io January 24, 2023 at 12:28AM
Show HN: Making an open source project regrouping the most interesting AI APIs Hi, I'm working on a project that regroups all best AI (AIaaS) from different providers (GCP, AWS, Azure, DeepL, etc.) [in one API]( https://ift.tt/ZBqEzrw ). I've got asked the question : *why aren't you regrouping Open Source models (instead of proprietary APIs) into one repo?* well because it doesn't make sens to deploy and maintain large pytorch (or other framework) AI models (especially for document parsing, image and video moderation or speech recognition) in every solution that wants AI capabilities. So using APIs makes way more sens. Deployed OpenSource models are being included using different APIs like HuggingFace and other equivalents. The current plan is to add some of these AI capabilities into [n8n automation]( https://ift.tt/PIRtKwB ) and [Odoo App]( https://ift.tt/ZN0YWqx ) (*receipt, resume* and *ID document parsing, content moderation* and *translation*) . Some other capabilities can include : *summarization, keyword extraction, sentiment analysis* for text data and also *speech to text* or *image* and *video tagging*. Do you know other Open Source projects You want this could integrate to ? https://ift.tt/ZBqEzrw January 23, 2023 at 03:39PM

Show HN: Codex – Find and Replace for Code Most editors' find & replace features are still very close to the original design intended for text documents, so they become unwieldy when you need to match across newlines and indentation for example, or when a parse of the code is necessary to capture a particular expression. Codex is an attempt to rethink what find & replace should look like in a modern code editor. It defines a simple but powerful syntax for describing code modifications, combining plain text, regular expressions and Tree-sitter queries, along with sensible handling of newlines and indentation*. It can be used just like regular plain text find & replace, but allows freely mixing in regexes and Tree-sitter queries as more flexibility is needed. It introduces "line quantifiers" for matching a bunch of lines at the same nesting level, so basic structural changes can be achieved without even using a query (see the JavaScript function example in the link). I designed Codex with a specific use-case in mind (the one I show in the video), so any suggestions for other things it should support would be much appreciated, as well as general feedback. *Indentation is relative and space/tab agnostic. https://ift.tt/5xTWDdt January 18, 2023 at 02:26PM

Parseable can ingest data from existing logging agents (FluentBit, LogStash, Vector, syslog-ng and more) using HTTP + JSON output. Ingested logs are stored as semi-indexed Parquet files (on disk or S3). You can query the data with builtin query engine using SQL or use a query engines of choice like Spark, Presto, Trino and so on. We also developed a Grafana data source plugin that lets you visualise log data via Grafana. Sample dashboard link in readme. As log data grew, our industry has responded with SaaS and fully managed offerings, but if you're looking for freedom, interoperability and full control over your data - there are no great options.

Show HN: Vento, Screen Recorder that lets you rewind and re-record over mistakes Hey folks, we made this screen recording tool to fix one simple problem - fixing your mistakes easily when recording so you don’t have to constantly restart or stitch. I’m not particularly great at presenting and so mistakes will inevitably happen during a screen recording, and it’s worse when you’re already 5 minutes into your recording, forcing you to restart completely. Please check this out and let us know what you think! https://vento.so January 17, 2023 at 04:01AM

Show HN: Caff.ai a Caffeine Manager for better sleep and more energy Hey HN, I often don't know if I can have a coffee at 2pm and started logging my caffeine intake so I wouldn't be up until 2am. For me it was never as easy as a cut off time (ie stop coffee at 1pm) because I vary the amount and timing of my coffee day to day. I made an app that helps you stay in your custom 'daytime target range' and under your 'bedtime target' caffeine level. It can predict how much caffeine you'll have at bedtime and tell you what time your caffeine will be below a configurable sleepable level. I also added a feature that gives you a notification 30 minutes before you can have your last cup of coffee and still be under your bedtime target at bedtime. This helps you stay maximally caffeinated while minimizing the negative effects. I have over 600 drinks in my drinks list, and I'd appreciate any feature suggestions or tangential app ideas as well. https://ift.tt/IoxXOKZ January 16, 2023 at 04:00AM
Show HN: Free Online Course – Debugging Difficult Conversations As an engineer I get frustrated at other training courses that talk a lot of theory, but don't have a lot of practical advice and tools to actually help. So, I built an online self-paced training course on difficult conversations (think feedback, salary negotiation, etc) that I wanted to share with the community. I like to make my training courses more "algorithmic." A process you can follow to approach a Difficult Conversation, get in the right mindset to tackle it, and prepare what you need to that allows you to do it well. This course will teach you: - What Difficult Conversations are and what happens when you ignore them - Why having Difficult Conversations can be beneficial to you, your team, and your career - A framework (and accompanying worksheet) to help you prepare for Difficult Conversations https://ift.tt/wxSaqdh January 16, 2023 at 03:49AM
Show HN: Group accountability for atomic habits (iOS) I started this project by running 10-day group challenges on Whatsapp. The group was gathered via a Webflow landing page, Google forms, Zapier and a PayPal button (here’s what I posted on HN at that time - https://ift.tt/8AYLK5U ). The WhatsApp challenges turned out to be a hit with over 85% checking in daily and 45% repaying to join multiple challenges. After having tried Streaks, Habitify, GTD, reminder apps, google calendar, Notion...etc—I was still having trouble staying consistent with my personal/wellness goals and habits. Methods from Atomic Habits by James Clear—are what worked best for me—but sticking to it alone was hard. For example, I had a daily push-up reminder on my google calendar that I ignored for almost a year. Fast forward, I’m now on day 120+ doing push-ups, meditation and waking up before 6am—after participating in group accountability challenges :) To see if we can scale it to help more people and potentially build a community-driven business—we just released an iOS app. Recap of how it works: - Join 10-30 day accountability challenges in small groups of 3-12 people - Commit a daily goal and check-in with the group on whether you didn’t or didn’t do it - Daily visual progress reports, reward credits/penalties and support from others helps everyone stay on track - Create and join private challenges with friends Would love to have you try it by joining a challenge—and see if could help you become the person you want be for 2023! https://ift.tt/ufVpYvi January 15, 2023 at 05:46PM
Show HN: RecoverPy 2.0: Recover deleted or overwritten files from your terminal Repo: https://ift.tt/YzGbBrt Hi! I just released RecoverPy version 2.0.0 and wanted to share it with you. RecoverPy is a tool with Terminal User Interface to recover deleted and/or overwritten data from your terminal. Version 1.0.0 was released probably around 2 years ago and I was quite amazed by how popular it got :) The initial audience was people trying to recover lost files, but it stuck with hacking/forensics community, I even got to receive mails to appear in hacking magazines and blogs. That was quite unanticipated but I'm glad it's useful to other people :) I got the idea when I was a noobie coder and, among other flaws, didn't use any VC. I worked all day long on a script when instead of outputting my script execution to a file I... output my log file content into my script file, then bam, my script was gone. I searched for solutions to recover it, the thing is it was not just "deleted", the file was still present, but its content has been overwritten. So after some research, I found it was possible to recover it with mostly a combination of grep and dd. RecoverPy is just that, it uses grep and dd under the hood and eases the whole process. So in the past few weeks (a few hours during past weekends) I worked on an entire TUI framework switch. Previously I used a dated, unmaintained Python TUI framework, finding a sexy and fresh one was quite difficult when I started the project :/ But months ago I saw the textual project and was amazed by the result. I was only waiting for some widgets to be available (I didn't want to reinvent to wheel) to jump into it. Textual is just amazing honestly and I can only recommend it if you need a Python TUI framework. I'd be happy to hear any feedback, issue, bug, etc. RecoverPy worked quite well on previous version, 1.5.2, the heavy rework may have introduced some new bugs. Furthermore, if you want to contribute you're also more than welcome! RecoverPy code is quite simple and textual TUI framework enables a modern asyncio workflow and I think, is a good playground if you want to step up. https://ift.tt/YzGbBrt January 14, 2023 at 09:02PM
Show HN: Use predictive modeling to win your bracket competition Hi! I made this as a side project this week to submit a bracket for our friends' NFL playoff bracket competition. It is all html and vanilla JS, runs directly in the browser, and is pretty fun to take for a spin.

Show HN: Sleuth, open source workspace search in natural language Hey everyone, We know how hard it can be to ramp up and learn the ins and outs of a new company. - “Who should I talk to about customer onboarding?” - “What was that project the onboarding team shipped in June, that had a massive impact on step 3 completion rate?” Instead of asking someone the same question that’s been asked hundreds of times before, it’s more efficient to find answers in existing documents and past conversations. The problem is, this data is spread out across dozens of workplace apps, with search features that all work differently. That’s why we’ve created Sleuth, an open source library that allows you to search through your company’s entire history using natural language. It understands the intent of your question, not just the keywords. Here’s a demo: https://ift.tt/ktyqFsE You can fork our repo ( https://ift.tt/ApY16ox ) and try it right now, or book a 15 min call ( https://ift.tt/z6uy2Ya ) with us to share your feedback. How does it work? Vector embeddings are generated for slack messages using OpenAI’s text-embedding-ada-002 model and stored in a Pinecone vector database for easy querying. How is this different from Glean? Glean is great, but we wanted to introduce a product that anyone can fork, use, and customize without ever talking to a sales team. Building in public makes for better products. What integrations do you support? Just Slack to start. What other integrations would you like to see? https://www.getsleuth.xyz/ January 13, 2023 at 01:10AM
Show HN: Fern, a language for defining REST APIs that compiles into OpenAPI Hi HN, this is Danny, Deep, and Zach. We built Fern after our previous ed tech startup failed. We were frustrated with how much time we spent writing “API code” instead of working on the actual product. We tried to use OpenAPI but we were underwhelmed - the generated code wasn’t idiomatic and it still required manual work (custom templates, scripts, manually publishing SDKs to registries). The Fern compiler takes your API as input and invokes generators that output things like: SDKs, server code, a Postman collection, and an OpenAPI spec. Some technical highlights about the compiler + generators: - The compiler (available as a CLI) handles syntactic + semantic validation. It also includes a linter that encodes best practices. If your API Definition compiles, you can have high confidence that the SDKs will generate correctly. - After all the parsing and validation, the compiler outputs an intermediate representation that gets handed off to the generators. This prevents each generator from re-implementing the same parsing and validation logic. - Each generator is implemented in the language it is targeting - e.g. the Python generators are written in Python, the TypeScript generators are written in TS. It makes the SDKs more idiomatic because every programming language generally has the best tooling/libraries for generating code in itself. We also think it’ll make community involvement + contribution easier. - The generators can output the code to disk, but also push the code to a Github repo and publish the SDK directly to registries (e.g. npm, Maven). We are looking for devs to use Fern for API development. If you have any feedback about the process, compiler, or the generated code, we’d love to hear it.

Show HN: Syncthing-map – a utility to map syncthing devices and folders If you use the excellent Syncthing[1], you may quickly be lost in the various shares between devices. I was. This was the trigger to write a small application that creates a map of your devices, their folders, and how each is shared. It is directly based on the configuration file of each device. The stable version[2] generates a HTML file you can render in a browser to show the map (based on mermaid.js[3]). I just released an experimental feature[4] that starts a web server which will dynamically create the map based on configurations shared by the devices. Binaries are available as well[5].

Show HN: Ecode – A minimalist and fast open-source code editor Hi HN! I've been working on a code editor and I think that it's mature enough to catch some interest. It's using a custom GPU accelerated GUI written in C++. Currently implements some interesting features: LSP, terminal, auto-completion, linters, formatters, custom keybindings, plugins and more. It's a hobby project but still intends to be an alternative to other popular code editors like Sublime, Kate, Lapce, Lite XL (and takes inspiration from them). The project was born as a playground for the GUI I'm developing (eepp GUI) and is advanced enough to currently be my main code editor, but it's a work in progress, and many features are still pending. Some minor hints on how to use it: Folders are used as project (and .gitignore is used to ignore files) The wheel icon on the top-right has all the options you need (Ctrl/Cmd + M to show). Some keybidings to navigate any project (navigation is keyboard driven): Ctrl/Cmd + K = Locate Files Ctrl/Cmd + Shift + F = Global Search Ctrl/Cmd + Number (Go to tab #) https://ift.tt/A7wOYps January 10, 2023 at 10:51AM
Show HN: PipeScore – FOSS Bagpipe Notation Software I've been working on some version of this since May 2019. It is a web app that allows writing out music for the Highland bagpipe. While it uses the same notation as normal music, bagpipe music tends to have a greater focus on gracenotes (embellishments). Most music software does not deal with this very well (e.g. MuseScore just displays a list of every single possible embellishment, of which there are hundreds [1]). PipeScore instead takes advantage of the fact that the form of many embellishments is dependent on the notes adjacent to it, allowing it to reduce the number of options down to just 13.

Show HN: Tortoise TTS as an at-cost open-source pay-per-second API Tortoise TTS is the best TTS available today. We built an open-source, at cost, pay per second API for it. The quality of intonation it generates is unparalleled, and we hope our at-cost API will make it easier for people to build on top! This allows folks to run via a single API call - it costs $0.03/query. The WAV file is downloadable, we apply no restrictions. We're open-sourcing all our work — we made Tortoise run 30% faster, and have more improvements coming. If you're keen to contribute we can help with ideas, pointers, compute and data; just DM us. Our fork with the improvements can be found at https://ift.tt/usRGhbj . The deployment code can be found at https://ift.tt/SqRZb10 . There are already great alternatives for using : i) @mdnest_r's awesome Huggingface Spaces, ii) original Google Colab, iii) host it yourself. Our work should accelerate those who need an API, don't want to spend time/$ hosting and need a scalable infra backing them. We're especially excited about combining text-to-speech with content generated from LLMs, and about how it fits into video creation tools. Tortoise in its current form is also inaccessible to non-technical users, which is why we are also providing a simple UI on top (also "at-cost"): https://tts.themetavoice.xyz To use, generate an API key on https://tts.themetavoice.xyz and call via POST request. Or use the web UI. Or run your own deployment. https://twitter.com/vatsal_aggarwal/status/1612536547248836608 January 10, 2023 at 01:35AM
Show HN: I asked ChatGPT to convert a Chrome ext to a Firefox ext I told it to create a virtual machine first: I want you to act as a Linux terminal. I will type commands and you will reply with what the terminal should show. I want you to only reply with the terminal output inside one unique code block, and nothing else. Do no write explanations. Do not type commands unless I instruct you to do so. When I need to tell you something in English I will do so by putting text inside curly brackets {like this}. My first command is pwd. Then I told it to create a python script to do the conversion: {Create and write to the filesystem a python script called convert.py that takes a URL as its first argument. The URL is a chrome extension. The script then converts the extension to a Firefox extension and saves the result in a directory called "res". Make sure the script works with an actual URL to a chrome extension on the Chrome Webstore. It requires you to possibly download the extension first from the URL. Also make sure the generated Firefox extension meets all the requirements and the Chrome to Firefox conversion takes place for all assets in the extension, it includes the content scripts, etc. Only print done to the terminal here when finished.} Then ran it with this URL (URL to Google Translate Chrome ext): python convert.py "https://ift.tt/YFHC5ce" It actually created a zipped Firefox extension with the manifest file converted correctly, etc. January 9, 2023 at 09:50AM
Show HN: Have voice-only virtual coffees with fellow HN'ers I'm running several voice-only virtual coffee events on the Discord server in the URL, only for today. The rules are pretty simple: 1. Wait for the "event" to start (see times at the end) 2. If there are no tables with 1 participant, join any one. 3. If there is a table with 1 participant, join that one. 4. When the event ends, all the voice channels are deleted and you have to wait till the next event starts. I initially wanted to build my own web app but then I realised it would be so much easier to just leverage Discord's infrastructure. I also built a bot in a couple hundred lines of Go code (love the language!) to bulk create/delete voice channels. I intentionally left it super basic to validate if there's a need. I personally would love to have virtual networking events, but then again I know I'm somewhat odd as I come from a sales background. If you're interested/want to take part in more of these events, check out my profile where I have some contact options.

Show HN: I Market-Make AWS Cloud Contracts to Save Companies $40M+ Hey HN: Kaveh here, the founder of https://www.usage.ai/ We help companies drive down AWS EC2 spend by buying and selling 3-year no-upfront reserved instances. Why? Because there's almost no liquidity on the AWS EC2 RI Marketplace and it can take a while, if at all, to sell an RI if you need to stop using one. Previous to founding Usage, I worked at JPMorgan Chase as a summer analyst. Here's how it works: We are typically brought in by a DevOps manager to cut AWS EC2 costs. The app is entirely self-service and the savings are generated automatically, typically we do this live on a call. On average, we reduce AWS EC2 spend by 50% for 5 minutes of work. To reduce by 50%+, we've built a pool of reserved instances that's shared across our pool of customers. When a customer scales up their EC2s, Usage buys RIs. When a customer scales down their EC2s, Usage sells RIs. At this point, we've saved companies tens of millions of dollars in spend and have a lot of liquidity, so we take on very little risk. We make money off of a 20% Savings Fee. Happy to chat directly kaveh@usage.ai Have you experienced any issues with managing your company or organization's AWS expenses? We'd love to hear your feedback and ideas! January 7, 2023 at 09:15AM
Show HN: ACOS: Build and share competitive turn-based browser games Hi everyone, This is a little tech demo I've been working on the past 2 years. It's been up for 1 year now, and has since had a few major updates. I have a soft spot for games with ranking systems, and I wanted an easy way for developers to create games with the competitive element abstracted away. The current games are built with ReactJS, so it's pretty easy to onboard if you are a web developer. All games developed for ACOS come with these features: - Real-time turn-based for browser - Simulator for game development - Client / Server architecture - Easy multiplayer with simple JSON game state update - Single player, Team-based, Battle Royale, and Free-for-all games supported - Matchmaking for Rank / Casual play - Room Scoreboard - Game Replays of every match - Error Logs - Global Rankings - Global Top Scores - GitHub Integration with acosgames organization - Discord Integration for matchmaking / game events - Simple deployment and version management It's a ridiculous endeavor, but I'd like to invite the world to my playground and help me drive features and technology forward. I may allow AI bot battles in the future against any of the hosted games, but I will prioritize based on the will of the people.

For the past two years I've been working on Tablane [0]( https://ift.tt/iOk3taX ) a task/project management tool, with features like: - Collaborative Editing (google docs) - Optimistic updates with RTK Query - Realtime sync with Socket.io - An awesome design Let me know what you think! Ask me anything! How I got here: 2020: I was developing a TTT [1] (Trouble in Terrorist Town) plugin for my minecraft server, when I started to require a project management tool to keep track of the features I wanted to implement, originally I used a text file, but after some time I started using products like ClickUp and Monday. But not long after I hit several paywalls for features that I wanted to use (Custom Status, Limited Number of Boards, ...) Soon after Tablane (originally task-board) was born. I started building the website using plain HTML, then found out about React and completed Colt Steele's "Web Developer Bootcamp" [2] and "The Modern React Bootcamp" [3] and started re-writing Tablane in React, and started adding feature after feature. Now I am about to finish Highschool and originally I thought about applying to college and spending another 3-5 years there, but after the positive feedback I got on a three month internship I did at ContentPepper, and seeing how my own projects developed, I decided to look for open Developer positions, to work with a team of experienced developers so I can learn even faster.

Show HN: Ello (YC W20) – AI-reading tutor for kids that works with real books Hi HN, We’re Elizabeth, Catalin, and Tom - the founders of Ello ( https://ift.tt/fqCFK5v ). Ello is an AI-powered app that mimics the one-on-one interaction of a reading tutor by listening to, encouraging, and coaching kids grade K-3 as they read out loud from a real book. We posted on HN back in 2020 when we launched Trustle, a company designed to pair families with dedicated experts in child development. We learned from that experience that parents don’t want a consultant, but they do want actual help with specific challenges—one of the biggest being reading. Prior to COVID, 65% of 4th graders in the U.S. were reading behind level. The most recent National Assessment of Educational Progress report revealed that reading levels have dropped even further, to the lowest level since 1992. These disheartening statistics reinforce something we learned during our time at Trustle—of all the pain points parents face in raising children, reading can often be one of the most critical yet most difficult to address, especially if the child doesn’t like to read. In an effort to help reverse this trend, we used advances in speech recognition - driven by self-supervised learning - to create a virtual experience designed to provide effective reading support. It's no substitute for attention and coaching from a caring adult, which is obviously what kids really need, but unfortunately that is not always available. If every child had consistent access to 1:1 reading support and every parent or caregiver had the time, language skills, and confidence to help their children learn to read with no outside assistance, then there would not be a need for a technical solution. Unfortunately, we know not every child has this access, and many parents are looking for extra support. That's why we've built Ello. If you look at a great teacher or parent working with a child, they are talking to each other. Ello uses a speech recognition model that listens to what a child is saying and provides the appropriate phonics based coaching, as well as commentary and help. As a child reads across the page of a physical book, the Ello app tracks the child’s progress and picks up when they miss a word or get a word wrong and then steps in just like a good reading coach would. One criticism that we’ve heard since launching is that we are trying to replace the sacred role of a parent teaching their child to read. We say, “Not at all!”. Ello can serve as a resource for every type of parent without being a “replacement”, which is impossible in any case. We’ve had most success with children who are reluctant readers. Ello provides a fun environment to practice reading without the pressure of an adult watching you. We’ve seen kids who flat out refuse to read start to enjoy reading in a short period of time. We are highly privacy oriented; unlike most apps relying on speech tracking we can work completely on device with no internet and no audio data shared back with us. We launched in early in 2022 and have come a long way since then. The model works like this: we mail customers five books and a prepaid return shipping label every month. At the end of the month you mail the books back or keep as many as you want for an additional $5 apiece, and then we mail you next month’s box. Our reading specialists help determine the appropriate reading level for every child and make sure that we are sending books to match. Right now we support roughly K through 3rd grade, although Ello can be effective for some Pre-K kids as well. We know there are many parents on HN, including those with young children. We would love to hear about your experiences and needs around your children’s reading journeys and your perspective on how something like Ello might help. Or, if you’re in the US, give us a try - you can get a free month with code ellohacker. And of course we welcome any feedback, questions, and ideas!

Show HN: An open source tool to generate Jet Engine compressors Hi everyone started this project a year ago to generate the CAD for a Jet Engine Axial Compressor. I am now open sourcing this tool that can take in a JSON file with specs and generate the CAD assembly. Still has a lot of work to improve designs but there isn't anything the Open Source community can't accomplish! https://ift.tt/cVL1gx7 January 5, 2023 at 12:22AM
Show HN: Freelancer Salary, calculator to match full time salaries My #2 in a string of websites I'm trying to make this year. When evaluating freelancing offers, I found myself writing a little script that did the math on how much more I'd need to charge. Days off, self employment tax, health insurance.. lots of factors. This simple web calculator does it for you. Let me know if you have any feedback or additional factors I've forgotten to add! https://ift.tt/CrexWHw January 4, 2023 at 01:08AM
Show HN: Hetzner-k3s v1.0.1 is out with autoscaling support This is the newest update to my CLI tool to quickly create cheap Kubernetes clusters in Hetzner Cloud. This update adds autoscaling support, so clusters created with this tool now can behave similar to managed Kubernetes clusters, which I think is awesome. I received a lot of feedback since the last update so I hope anyone interested could try the new version as well. Thanks a lot for the feedback so far!

Show HN: Spall – WASM-based profiler for JavaScript and C in ~5k lines of Odin [I'm the author] Spall is a web-accessible profiler that I made to help my web-dev friends load gigabyte+ JSON traces without lunch-break-long load times. Recently, Spall got experimental support for auto-tracing with binary traces (along with an in-progress native-port, to give it more memory headroom), which was used to help track down and fix some hard-to-spot lock contention issues in the Odin-language compiler. I demoed it at the Handmade Seattle conference in October, https://ift.tt/HUWcyNB , with a head-to-head against Perfetto, another big web profiler. I'll be around to answer any questions. Thanks for looking at my project! If you like Spall, you can catch my other projects over at https://ift.tt/C7Xn3yk . If you happen to be hiring I'd love to hear from you. Looking for something fun and new to do after a long sabbatical, working on cool open-source projects! https://ift.tt/sRWonVi January 2, 2023 at 07:37PM
Show HN: Block positive reinforcement from HN with uBlock Inspired by the nytimes post "Luddites don't want your upvotes", and presumably being a Luddite myself, I have used uBlock to block my Karma score at the top of the page. I found myself (on old account) reflexively checking my Karma score and found myself responding emotionally to it. I do not like this. Positive reinforcement can be a dangerous thing! And negative reinforcement make me feel a bit crap. I'm going to post what I think is the right thing, votes be damned! However I do see the use of downvotes for getting rid of stupid comments and spam as a good thing. I see the use of down/upvotes for political ideologies as a bad thing. SO, I simply used uBlock to permanently block "Karma" across HN topbar. Simply go to uBlock icon, press Element Picker Mode (the eyedropper), select the Karma number, and select the Create button. Done. January 2, 2023 at 07:39PM
Show HN: Detecting collision between 500k circles below 5ms Heya. I created a flexible collision engine for broad detection in C that's also pretty fast. Personally that's my best, so I wanted to show it here. Although... still not as fast as DragonEnergy's one that supposedly handled millions of agents bouncing off each other every frame on an old i3, haha. I hope I get better at this! He set the bar pretty high for me. I was considering including some small function that tries finding the nearest entity, although I think it might be better to simply use query for that matter. Perhaps in the future I will get a good idea of how to do that more efficiently. This is not a clickbait. Although generally you also call other functions in a tick, a collision check between 500,000 circles ("circles", not "squares", because distance is checked and forces are applied based on the angle between) is done below 5ms on not really that demanding hardware. I achieve lower times than that on my budget laptop, slightly more on my PC (yeah, weird). The total time spent in a tick is 3-4 times that. https://ift.tt/StpRAgP January 2, 2023 at 01:38AM
Show HN: My programming language, building in public for 1 year My weekly(ish) video logs tracking my progress of building a completely sound statically typed language and structural editor. The motivation is to make lots of invalid programs unrepresentable. https://ift.tt/UFYSlZr January 1, 2023 at 05:12AM
Show HN: I made a simple, open source, chromatic tuner mobile app I'm a musician by night, software developer by day, and one of the minor frustrations I've always had was trying to find a simple tuner app for my phone. Looking at both the iOS and Android app stores, you'll find a lot of the top tuner apps are rather bloated with ads or subscription callouts. I thought I'd create a dead-simple minimalistic mobile chromatic tuner the way I would like it - open the app and tune my guitar. My work is in web with NodeJS and React, so I chose React Native since it was the easiest to understand coming from React. Flutter was also an option since the company I work for has a team working in that, but I thought it would be a bit too much effort to learn Dart. I learned a bit more about React rendering with this project as well. The main issue I had was trying to have a React state variable be constantly updated with any frequencies detected from the mic input, but that ended up causing substantial slowdown due to so many rerenders, so I opted to use a React ref to maintain any detections, and then only update the React state when there was an actual note. I feel like sometimes the UI has trouble updating occasionally when my iPhone is in battery saving mode, which I guess might be related to throttling the audio sample rate somehow, though I'm not entirely sure. Friends and family haven't noticed this, so it may be due to my old 2016 iPhone SE :P. The apps you can find on the both the iOs App Store and Google Play (free!). https://ift.tt/uGEi1Wd https://ift.tt/DJlM2OA... Would love any feedback! https://ift.tt/JAH5vpt January 1, 2023 at 02:21AM
