Show HN: Restfox – A web based HTTP client inspired by Insomnia and Postman Hey HN, I built this because I wanted a portable version of Insomnia I could access anywhere I am, without installing anything. The application is a PWA, so it will not load resources again after the first load, unless there's an update. It uses IndexedDB and loads quite fast even with a lot of nested requests and folders. Import from Postman and Insomnia is available making it easy to import your pre-existing request collections. Only limitation is that it only supports CORS enabled endpoints for now. I plan to add cors proxy support later on. There is of course the electron build ( https://ift.tt/09XEKwU ), which can be used to bypass cors but that kinda defeats the portability of the app but it is an option.

Show HN: Reach 100 – a (unsolvable?) puzzle game I recently remembered a game we used to play with pen and paper some 20 years ago, where you need to fill a 10x10 grid writing numbers in the grid up to 100 following 2 simple rules. After showing it to my kids I thought it would be nice to adapt it digitally so that they could play it more often (not needing to draw the grid etc.) and so that other people could play it as well. What I'm really interested in with this submission (beyond general feedback) is wether anybody knows the origin of the game and if it's solvable. Because that's the catch, my highest score of all time is 97 and it doesn't seem to be possible to go higher. I have the feeling this game is an adaptation of a more general problem and probably has its origin in some lecture. So, once again, if you know where it comes from I'd be really grateful. Alternatively I would love to know if there is a possibility to prove if it's solvable or not. (It&#

Show HN: Investorsexchange.jl – parse trade-level stock market data in Julia Backstory: I wanted to play with intraday stock data but couldn't find a free dataset anywhere. IEXCloud [1] offers API access to 1-minute granularity intraday historical price data, but I was worried that it could get expensive or unwieldy to build up a substantial dataset via API calls. Plus, IEX gives out their raw data for free. I probably should have just used the IEXTools python library [2] to parse IEX's raw data dumps, but I was working on a Julia project, so it felt more thematically appropriate to build a new tool from scratch. I haven't been actively using InvestorsExchange.jl a lot lately, but it's made me the proud owner of a 50GB SQLite DB dump covering several years of trade data, and I think it would be awesome if I could help folks in the HN community more quickly build up this kind of dataset for their own curiosity or research. Feedback is also greatly appreciated! [1] https:

Help Make Muni Safe for Everyone By Mariana Maguire New Muni “no harassment” symbol The safety of our customers and staff is a top priority for the SFMTA. That is why we are launching MuniSafe – a campaign to increase reporting of gender-based harassment through recently expanded incident reporting options. If you experience or witness an incident, help us make MuniSafe by reporting it using the Muni Feedback form at SFMTA.com/MuniFeedback, the 311 mobile app or by calling 311. Non-English speakers should call 311 for language-assisted reporting. Gender-based harassment takes many forms, affects many people and is absolutely not tolerated on Muni. Survivors should report incidents to the San Francisco Police Department if they feel comfortable doing so. By also reporting incidents directly to the SFMTA, you will help us track events that occur in our system so we can build better safety responses and direct resources to reduce gender-based harassment.

Hope it's not considered spammy! I and a collaborator who writes sci-fi just released the short story "The Great Filter Button" - https://ift.tt/XRzIjgT Here's why it's relevant to HN: most of the text for it was generated by GPT-3 (with human curation, using SudoWrite) and it was entirely illustrated using DALL-E 2 and MidJourney, and a bit of DreamStudio aka Stable Diffusion (of course with human selection of prompts) AND it narrated using neural voice synthesis (via BeyondWords).

Muni Color Schemes Through the Years By Jeremy Menzies Over the 110-year history of the SF Municipal Railway, our transit vehicles have been painted in six main color schemes (known as “liveries”). Here’s a short look at those paint jobs, from the oldest streetcars to our newest buses.  The timelines of these liveries overlapped and old colors were not always phased out even after a new color was introduced.  Not included here are the many colors of cable cars , historic vehicles , variations on the main colors, or any special paint jobs used. The Original Grey and Red: 1912-1939 When Muni started in 1912, vehicle paint colors were used to distinguish one transit service from another. Muni’s very first streetcars were painted grey with red windows and roof. Gold was used for lettering, vehicle numbers, and decorative lines. This combination gave the cars a simple yet elegant look. Seen here at Green Division rail yard around 1980, Streetcar 1 was built in San Francisco in 19

Show HN: I used DallE to create default avatars on my Creator community website I'm an indie dev and I built a community for creators to get together and collaborate with each other. Mostly for amateur creators, but some famous ones use it as well. It has about 700k users so far. There are about 100k of those users who don't bother to upload an avatar, so they've had a boring default avatar for nearly 7 years. Today, I used my credits on DallE to do make them a bit more fun. Since the creators self-identify, I was able to create specific kinds of avatars for them. For example, if a creator is a writer, my DallE prompt would be: "an oil painting portrait of a serious-looking owl, standing in front of a typewriter" Voice Actor: "oil painting portrait of a robot who is made out of a microphone, wearing a hat and headphones" Comic Illustrator. This one was a little more tough, so I chose 'tablet' as my key object: "Oil painting portrait of a bro

Show HN: SaaS for analyzing Bitcoin price movements Hello everyone! Our software offers a SaaS for analyzing Bitcoin price movements. We built an MVP model which recognizes levels in which BTC is at the top or bottom of the cycle. It is primarily intended for investors who are not financially sophisticated as a possible help to protect their investment. A short story about the creation of the product: A few of us, friends and ourselves, have always been maddened by the regular loss of the largest part of unrealized profit during bear markets which tend to be very hard on retail investors.On the other hand, a lot of friends blindly invested into bitcoin at ridiculous price levels based on hypes, bad instagram and YouTube influencers and mouth of word. We think that a large part of BTC and crypto investors live in a similar situation. With this goal, we teamed up with experts in the field of data science and finance, and created an algorithm that gives the BTC price score based on crucia

Show HN: Hangman meets Wordle webapp in Angular Hey HN, I am a novice web developer, and I built a new webapp game in Angular that combines the game play of Hangman and Wordle. I chose this project because I wanted to learn Angular, while also developing something useful. I have some prior backend experience. And, I was pleasantly surprised with how much you can achieve in the pure JS/Typescript these days. For my app, the backend only sends the daily puzzle data in JSON, while the entire game logic and interactions are completely implemented in the frontend. I wrote around 4000 lines of the frontend code for this project. For me, the best part was RxJS integration in Angular. It also had a fair amount of learning curve. However, once you have learned the basics, it saves a lot of redundant boilerplate code and makes the code more readable and clean. You can play the game for free and there is no sign-up required: https://10letters.app The game does not save any user data at the server

Show HN: Browse HN Together in Three.js Hey HN, We’re Philip, Amby, and Declan, and we made “multiplayer virtual computers” that you can embed anywhere, including 3D spaces. We decided to build this because we noticed that embedding third-party apps and websites can be a nightmare due to incompatible platforms, security issues, and poor UX. Adding multiplayer functionality to these embeds makes this problem exponentially more difficult. On the backend, we’re spinning up a VM and running a resource-optimized fork of Chromium which we then stream to participants via WebRTC. Since we’re hosting the servers running the applications, multiple users can connect and control the virtual computer seamlessly, and their client just needs to handle a video stream.

As someone who's constantly on the look for new music to discover, I needed a better way to organize the albums I want to listen to, listened and liked. And also I would like to see the discoveries of other folks who I know I like. So I started creating the tool I wish I had in the first place. In Digs, the basic idea is that: - you can add music releases (albums, EPs, singles, mixes) in three lists: Want to Listen, Listened, Digged. You can also use tags and notes to better organize these lists. - you get a public profile where your activity is visible (i.e. what you added to your lists). Example profile: https://digs.fm/alskn . - you can add other people as friends. Then you'll see their activity in your home feed. - you can either like or add a comment to any activity of your friends (or yours) - you can explicitly recommend a release to one of your friends This is very early yet

Join here (100% perpetually free with no strings attached): https://brew.fm Some time ago, I built and showed HN[1] brew.fm, a tool helping artists remix each other’s work. It had been quiet, and I remembered how fun it was to work with the Spotify API, so I repurposed the tool to solve one of my own problems: missing out on new music of my favorite artists. I shared it on Reddit yesterday[2], and this seems to hit a spot for more people: so far 833 people connected their Spotify account. How it works: The tool simply shows your top 50 artists on Spotify over short, medium and long term, and checks those artists for new music. If you select a playlist, every artist involved in the tracks will be checked for new music, after which new releases are shown sorted by most recent release date. Here’s a video of me demoing the tool: https://youtu.be/Nh2Ognb4PgU

Show HN: Modifying Clang for a Safer, More Explicit C++ Modified C++ Inspired by the paper "Some Were Meant for C" by Stephen Kell, I decided to show that it's possible to iterate C++ to be safer, more explicit, and less error-prone. Here's a possible starting point: I didn't invent a new language or compiler, but took the world's best compiler, clang, and modified it to begin iterating towards a new furture of C++. Naming things is hard, so I call this 'Modified C++'. Some of the following could be implemented as tooling in a linter or checker, but the idea is to update the compiler directly. I also wanted to learn more about clang. This compiler needs a flag to enable/disable this functionality so that existing library code can be used with a 'diagnostic ignored' pragma. You can build clang using the normal non-bootstrap process and you'll be left with a clang that compiles C++ but with the following modifications: - All basic types (excl

Show HN: An HTML endless runner under 900 lines without frameworks or libraries My wife and I recently submitted to a mobile game jam on Newgrounds (yes, it's still around). What started as a question of whether we could do it somehow morphed into whether we could do without so many of the seemingly needless complications rampant in our respective industries. My wife thus did all the art as traditional frame-by-frame animation (no puppets or tweening) and I preceded without a game engine. I did use a pre-processor that gives JS a Lisp syntax (Parenscript), because C-syntax is gross. We hope the end result, while definitely of small scope, will serve to inspire some thought as to what is and isn't needed in your next project. https://ift.tt/z9eCfx3 August 19, 2022 at 11:12AM

Show HN: We built an AirTag-like network for sensors that talk to your servers Hi, we’re Simon, Don and Dan, and we’re developing infrastructure for enabling Bluetooth devices that can communicate with your web backend (we’re calling it Blecon). Think your own AirTags network, but for sensors talking to your servers. We’ve got most of the underlying tech for the network infrastructure in place, and now have samples of a first manufacturer device that supports Blecon - a small rechargeable accelerometer tag. Not much live yet, but we put a summary of this first device and how it works in the link (plus you’ll find some early developer docs for the network infrastructure itself). TL;DR the tag logs timestamped motion and orientation events, and then sends the data using Blecon when phones come nearby. The data arrives at your specified network endpoint as JSON HTTP POSTs, so it is nice and flexible for integrating into any web infrastructure or framework you might be using. The customer

Show HN: Pi-hole deployed at the edge on Fly.io and accessed via TailScale Hi, I just saw this tweet[^1] by @QuinnyPig that mentions accessing your Pi-hole while traveling thanks to TailScale and wondered how to deploy Pi-hole at the edge, instead of a home lab, for improved latency. My simple solution involves running it on Fly.io to make it easy to relocate anywhere, and embedding tailscale into the same firecracker VM (né docker container) to keep the infra dead simple and cheap. Naively deploying a publicly accessible DNS resolver is not ideal[^2] so the main constraint was to secure the VM by 1) keeping all public ports closed and 2) having Pi-hole listen only on the private network interface created by TailScale. It's all very straightforward but it's noticeably improved my bandwidth usage and page loading times across my laptop and mobile phone, so I figured I'd share. Suggestions for improvement are also welcome! [^1]: https://twitter.com/QuinnyPig/status/1558521941

Show HN: Learn words in a foreign language by typing I’m Brazilian and I made this tool for my brother to learn English. He’s also trying to learn the keyboard layout at the same time. So far he seems to be liking it and getting better. I manually built and open-sourced the dictionary on github, so anyone can contribute and add more languages. I’m doing that manually because I want to do that in the most easy and didactic way possible, with a very accurate translation and most used words. Ideally, in the next version, it will be using some sort of API or automated tool. I’m not sure how to make the dictionary work effectively because each description needs a very close translation (ideally as exact as possible). We’re not able to just copy words and descriptions because they won’t necessarily line up with the other language translations. We’re currently manually translating to be accurate, though ideally we can figure out a good way to scale this, if anyone has suggestions please let m

Show HN: OxideDB – Teach PostgreSQL Database How to Speak MongoDB Wire Protocol Hey everyone! I have created a product that relies on MongoDB for a document store but doesn't really need any of the distributed features to really justify having a hosted MongoDB or DocumentDB instance. Now that we're trying to turn this into a product, we're seeing that some companies have a little bit of resistance around managing yet another database. Most of our clients already have and manage PostgreSQL in one form or another. I knew that PostgreSQL already offered first class JSON support, but I didn't want to rewrite the application data layer from scratch if I could avoid it. That's when I started researching if there was a "proxy" that would translate the MongoDB protocol - that I was completely ignorant about - into PostgreSQL. To my surprise there was nothing ready for production use but I found MangoDB that later on became FerretDB. I delved into the code and was

With my two friends Sualeh and Shengtong I have been spending the last few months building a dedicated home for important, long-form conversations. We’re super excited to let the HN community test it out! We think that no existing platform for point–to-point communication prioritizes the conversations that you actually care about and that really matter. Instant messaging is filled with careless texts and stickers, email is filled with receipts and spammers, and physical mail, while better in those respects, is slow and cumbersome. None of the existing platforms are private enough. Anysphere attempts to fix this. It is private, secure, desktop-first and only allows people you added to contact you. Our whitepaper ( https://ift.tt/Cdj94b8 ) describes our privacy and security model in detail — in short, we protect all of your data and metadata against eve

Show HN: Bog Gobbler Word Game Two years ago my pandemic project was an online multi-player variant of Scrabble named Crossword Island Hopper where you capture territory by placing words on a board. It proved to be wildly unpopular. More recently I have been working on Bog Gobbler, which is a variant of Boggle where you capture territory by finding words in the grid. The territory-capture element is much more relevant in the multi-player game, but also affects the mechanics of solo games. This one is a little more popular and there is a daily solo challenge where everyone plays the same grid, with a global and personal leaderboard. You can go directly to the daily challenge at: https://ift.tt/XAJ8Ryc If you know how to play Boggle the one thing you need to be aware of is that after the first word you find, all subsequent words must include at least one letter that you already "own". https://ift.tt/AEQj7Gs August 14, 2022 at 12:11AM

It's essentially an 'agency of one' design and development service using a subscription or retainer model for billing (Stripe + Memberstack). I primarily focus on WordPress and Webflow design and development as I realized long ago that there's a huge demand for these services in the design / marketing agency space. I've had a lot of success the past year with this work, and surprisingly (or unsurprisingly) every single client of mine has been a larger agency needing additional help. That kind of makes sense because an agency can immediately see the value in what I offer without really having to be convinced. Recently I've introduced a weekly option for clients looking to launch fast and spend less ($1,000 a week, maybe not sustainable but we’ll see). I'd love to get more involved with startups needin

How Improving Muni Also Makes Life Better for Drivers By Andrea Buffa Photo credit: We Ride Australia If you mostly drive to get around San Francisco, you may be wondering, “what has the SFMTA done for me lately?” San Francisco is a “ transit first ” city, so at the SFMTA we focus our resources on making it easier for San Franciscans to get around by public transit as well as by biking, walking and personal mobility device. While it may seem like adding transit lanes and protected bike lanes doesn’t have anything to do with driving, in fact, it does.  Since San Francisco doesn’t have room to give more space to roads, we have to change the way we use the limited space on our existing streets. (Not that adding more roads reduces traffic anyway – check out this article .) City Traffic Engineer Ricardo Oleo puts it this way: “When you have a city like San Francisco that was built with density in mind, having everyone drive is not a viable option.
