Show HN: Restfox – A web based HTTP client inspired by Insomnia and Postman

cheap domain name registration
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://github.com/flawiddsouza/Restfox/releases/tag/v0.0.1 ), 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

cheap domain name registration
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's made for mobile but it works on desktop as well with keyboard shortcuts around the S key in a QWERTY layout) https://reach-100.com August 31, 2022 at 10:42PM

Show HN: Node Version Audit – Audit Your Node Version for Known CVEs and Patches

cheap domain name registration
Show HN: Node Version Audit – Audit Your Node Version for Known CVEs and Patches I wrote Node Version Audit to automatically keep track of Node patches, particularly for releases that fix CVEs. While it can be ran directly, it is designed to run as part of a pipeline to produce warnings if the runtime version of Node has CVEs, or is no longer supported. The cool part (IMO), is that Node Version Audit automatically keeps track of node releases and CVEs by parsing the change log, and so there is no curation needed to maintain it. I would love any thoughts! https://www.github.developerdan.com/node-version-audit/ August 31, 2022 at 06:15AM

cheap domain name registration
Show HN: I made a custom news aggregator that updates automatically Hello HN I visit a few sites news sites daily and wanted to see the headlines all on one page and also have it update itself throughout the day. It is not finished yet, but is usable enough to share. If you want to make a custom page, you can click the 'build your custom page' at the top, and select the feeds that are of interest to you. I haven't implemented it yet, but the feeds can be re-ordered as well, you just need to enter their names in the address bar, for example to show Tech Meme, BBC News and Tech Crunch you would write: nuntium.co.uk/f/?tm,bbc,tc Then bookmark that link to visit it later. It is very minimal and no login or account is required. It is very gentle on the sites it polls - it only polls them once every five minutes at the moment. I'd love to get some feedback on what other people think and if there are any feeds you would like to see on there please let me know and I will add them on :) https://nuntium.co.uk/ August 31, 2022 at 02:36PM

Show HN: Investorsexchange.jl – parse trade-level stock market data in Julia

cheap domain name registration
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!

Show HN: Adless – User-Friendly Monetization with Subscription Networks

cheap domain name registration
Show HN: Adless – User-Friendly Monetization with Subscription Networks Adless is like advertisement networks (e.g. Google AdSense), but for the subscription economy: We connect subscribers (instead of advertisers) with content creators without the need of a direct business relation between the two. Simply put, Adless sells subscriptions which content creators can partake in by delivering content in accordance with the terms (e.g. without display advertisement or grant access to paywall’ed content, which are the initial subscription offerings). In return, content creators earn a share of the revenue (+ we take care of pretty much everything customer, sales and technology related for them). Effectively, this is a "one subscription that works everywhere" value proposition for consumers, using collective bargaining power to keep the price reasonable. The dream is to replace the de facto ads-based revenue model (with its dependency on tracking and privacy-invasion) with a sustainable privacy- and user-friendly revenue model that does not involve any dependencies on user profiling. I’d love to hear your thoughts! You’ll find some live demos at https://adless.net/get-started . -------------------------------------------------------- Are you a content creator? Feel free to give Adless a try! The networks are currently (very) small, but we are working on bootstrapping them so any help in this area is much appreciated It doesn’t matter if you made a blog, a game, a SaaS or something entirely different. The aim is to eventually cover all these customer types and more so we would love to have you onboard if you want to offer your content without display advertisement or provide access to otherwise-paid content (full eligibility criteria available when signing up as an earner). We compensate based on time spend on content so no need to be clever about triggering page view events. https://adless.net August 30, 2022 at 12:50PM

Show HN: I used DallE to create default avatars on my Creator community website

cheap domain name registration
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 brooding chameleon, wearing headphones and a hoodie, standing in front of tablet" Producer: "Oil painting portrait of a happy hedgehog with headphones on, wearing sunglasses, standing in front of a megaphone" All four images on this thread: https://twitter.com/_buf/status/1564327370219261954 Overall, I generated over 200+ new avatars. What a fantastic bit of tech! August 30, 2022 at 12:32AM

Show HN: SaaS for analyzing Bitcoin price movements

cheap domain name registration
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 crucial market parameters. This score shows excellent results in real time and on backtesting. Our ultimate goal is to create a platform with various features, which will help retail investors to better navigate through the market, and to protect them from large losses. Therefore, we assumed that our USP has its audience among people who invest in BTC, and who had similar experiences in the bear market as we did. With the help of a landing page and paid Ads we want to test if a product market fit is possible with such a service. Unfortunately this turned out harder than we though. The problem lies in the fact the most popular social networks, among them Twitter as well, have problems with crypto advertisements. Although by definition we do not provide any financial product or services, not even financial advice, it may be that our service is interpreted that way and that we belong to a group where the space for marketing on social platforms is limited, rightly or wrongly. And we don’t know if we can change or adjust it at all, which drastically slows down our strategy of defining the product market fit. With that, we ask for feedback or advises to the following questions: -What do you think of our product? And do you think it is an idea that could be useful for BTC investors? If you don’t think so, how would you change/improve the product? -Is our product, like it is now, considered as financial advice? And is there anyway we can differentiate this kind of product from such a label? -How would you implement the product market fit strategy of our product in the fastest and most favorable way, if you could not publish advertisements on social networks? We are very grateful for any constructive advice or idea! You can find out more on our landing page (link above). Thank you!

In particular, the many years I've spent working at 80,000 Hours.

Show HN: Hangman meets Wordle webapp in Angular

cheap domain name registration
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. All data is saved in the local storage. So, you can play the game again in the incognito mode, or after clearing your browser cache. If you have any questions or feedback, please feel free to add them in the comments. Thanks! https://10letters.app August 28, 2022 at 01:07AM

Show HN: Make Any CLI into a GUI in Acme

Show HN: Make Any CLI into a GUI in Acme Hey HN. I've become enamored with the Acme editor. It's fascinating because it turns the Vim paradigm on its head: instead of maximizing your use of the keyboard, maximize your use of the mouse. I think this helps optimize for information management, as opposed to text manipulation. I realized a lot of the CLIs I use have the same structure, and with a small program I could convert them into GUIs inside Acme and make them much easier to use. Let me know what you think. https://github.com/hherman1/I August 28, 2022 at 12:45AM

Show HN: A Minimal PHP Wiki First, I'm by no mean a programmer. Second, I am reading HN for years, just registered to make this public and see if it can be useful for someone. I have nothing to gain monetary. A while ago, I decided that no blogging system was simple enough and I looked for a small wiki to use as a CMS/blog. Found WikWiki on C2.com and I mixed it with some basic Markdown syntax, a minimal template and added password protection. The result is a single php file, no database and no dependencies. Code is a mess, not modulable, probably wrong in so many ways, but it can probably used by some as personal notepad, wiki, CMS, blog, etc. Any comments appreciated. https://mindwi.se/?WikiMind August 27, 2022 at 02:46AM

The articles are parsed by a library that makes its best attempt to extract the main content. I only own a Kindle Oasis (10th Generation) and thus have only tested this on it. I’d imagine it looks fine on other Kindles, but you’ll have to tell me. Link to screenshots: https://imgur.com/a/8kKneH0 Really, I made this for myself as a quick solution for a personal need. But it seems like there are a few of you out there that would enjoy this as well. So I am making this public for others to try out. Let me know if this is something you actually want to use. If so, and the reception is positive, then I will continue to build it out to be better and more feature complete. In addition to this, would you enjoy a generic rss feed reader as well? — one that allows you to read any rss feed right from your Kindle’s browser? I can build this if that’s something you guys really want. https://kindlehnbeta.pythonanywhere.com/ August 27, 2022 at 07:49AM

I've also fixed numerous long standing UI bugs including: comparisons now load correctly on RDS and ElastiCache, sort by max ENI works, sort by RDS instance storage works, and all dropdowns have consistent behavior. For maintainers and contributors, all the frontend libraries are upgraded to their latest versions, https://github.com/vantage-sh/ec2instances.info . Going forward, we are aware that the homepage size is quite large and have plans to address this. We have tried to be good stewards of this project and evolve it carefully.

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 and there are a lot of rough edges. You can find a few screenshots of the basic functionality in the homepage, from where you can also create an account - https://digs.fm . I'd appreciate any feedback, thanks in advance! --------- EDIT: I figured it's worth expanding a bit on some highlights: - In the search box, apart from searching, you can copy/paste any release URL from Discogs/Spotify/Bandcamp/Mixcloud/MusicBrainz and it will basically fetch the release and then you can add it to your lists. - There are browser extensions for Firefox and Chrome, so that when you're on some of the aforementioned sites, and you stumbled upon an interesting album, you can click the extension icon and the item will be added to your "Want to Listen" list. - For certain releases, you'll notice there's an embedded web player, for convenience. https://digs.fm August 22, 2022 at 07:56PM

Show HN: Brew.fm – Let bots discover new music on Spotify for you Use Spotify? This tool will automate your music discovery for you. 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 . Enjoy! Very open to feedback.

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://github.com/trevorjay/Bondis-Heaps-of-Air August 19, 2022 at 09:42AM

cheap domain name registration
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 use case for this device is actually monitoring when and how long equipment is being used, but motion and orientation can be used to infer a lot of things. Interested in what ideas you have for services you could build with just this first accelerometer sensor?! We’re still developing the network product, but interested in feedback, ideas, questions and use-cases. And if you are really interested we do have samples of this sensor so feel free to reach out if you have a service you’d like to try building with it! https://www.blecon.net/analytics-tag August 18, 2022 at 11:29PM

Show HN: Pi-hole deployed at the edge on Fly.io and accessed via TailScale

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!

Show HN: StoneDB—A Real-Time HTAP Database Based on the MySQL Kernel

cheap domain name registration
Show HN: StoneDB—A Real-Time HTAP Database Based on the MySQL Kernel StoneDB is an open-source hybrid transaction/analytical processing (HTAP) database designed and developed by StoneAtom based on the MySQL kernel. It is the first database of this type launched in China. StoneDB can be seamlessly switched from MySQL. It provides features such as optimal performance and real-time analytics, offering you a one-stop solution to process online transaction processing (OLTP), online analytical processing (OLAP), and HTAP workloads. StoneDB is fully compatible with the MySQL 5.6 and 5.7 protocols, the MySQL ecosystem, and common MySQL features and syntaxes. Tools and clients in the MySQL ecosystem, such as Navicat, Workbench, mysqldump, and mydumper, can be directly used on StoneDB. In addition, all workloads on StoneDB can be run on MySQL. StoneDB is optimized for OLAP applications. StoneDB that runs on a common server can process complex queries on tens of billions of data records, while ensuring high performance. Compared to databases that use MySQL Community Edition, StoneDB is at least 10 times faster in processing queries. StoneDB uses the Knowledge Grid technology and a column-based storage engine. The column-based storage engine is designed for OLAP applications and uses techniques such as column-based storage, Knowledge Grid-based filtering, and high-efficiency data compression. With such storage engine, StoneDB ensures the high performance of application systems and reduces the total cost of ownership (TCO). https://github.com/stoneatom/stonedb August 18, 2022 at 11:26AM

Show HN: Allsearch – Making it easier to use different search engines seamlessly

cheap domain name registration
Show HN: Allsearch – Making it easier to use different search engines seamlessly Allsearch is a tool I made after getting fed up with Google's search results and reading up on conversations on HN about the state of search on the internet. This is a tool I made as a spiritual successor to GnodSearch ( https://www.gnod.com/search/ ), which I've seen in a couple conversations about search on HN. GnodSearch is great, but a bit barebones in terms of looks and functionality; Allsearch is my attempt to build off of it. Similar to Gnod, Allsearch allows you to apply any given search query to a search engine of your choice (either through only keystrokes, or via mouse). However, it also allows you to add your own engines to its catalogue, and allows you to define macros to use multiple engines simultaneously (useful for easily comparing engines). It's not feature complete; there are still some things I'd like to add in. There are way more engines I want to add to it's default catalogue, and I also want to add in the ability to export your settings to allow people to easily share their Allsesarch configurations. Curious about people's thoughts on it :) https://allsear.ch/ August 17, 2022 at 12:17PM

Show HN: A network for Americans who can't afford health insurance

cheap domain name registration
Show HN: A network for Americans who can't afford health insurance Hey HN, launched this recently and looking for early feedback. The problem to solve: In the US, patients who can't afford health insurance are regularly charged the highest prices for healthcare - prices that are deliberately inflated by 2x-4x above market. But theoretically they should be getting the best prices, because they are paying without the expenses and delays of insurance claims. However, insurance contracts are written in a way that prevents anyone outside a network from getting better prices than insurers. The Pocketero solution: An affordable non-insurance network for people who pay out of pocket for healthcare, especially those who can't afford health insurance. Network members get the best prices from network providers. If you have any comments about the design, implementation, business model, etc. - please share your thoughts! https://www.pocketero.com August 17, 2022 at 02:11AM

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 me know! https://www.termtyper.com August 16, 2022 at 11:16PM

Show HN: Augmented Reality Knowledge Management for Facility Maintenance Teams

cheap domain name registration
Show HN: Augmented Reality Knowledge Management for Facility Maintenance Teams Hello friends at HN. Aircada is an AR knowledge management platform to help facility maintenance teams capture, retain, and transfer knowledge. Here is a link to a demo video showcasing the features - https://youtu.be/QXwTlNC3C7A During the pandemic, we noticed that some technical achievements from Microsoft's Spatial Anchors were finally at a point of opening the door to adoption for a magnitude of AR use cases, that in the past, weren't a viable option. And paired with the processing power and lidar capabilities of new phones, it seemed location based AR finally wasn't a pain in the a%% to use. Until now, QR codes and advanced computer based setups were required, and just were not worth the effort for most. But now, all with a mobile device - scan an area, place AR content, then scan that area again and have it show up exactly where you placed it. Awesome. However, there were still some problems with Microsoft's system. Locating AR content sometimes took 30+ seconds, and cost up to a dollar to do. So we built on top of their system and managed to cut that cost by about 10x, and increase the speed of locating content by about 10x. And by doing so, the use cases that opened up were quite vast! With our backgrounds in industrial automation, we set out to address the following problem - The growing industrial skills gap. The US Department of Labor estimated the 50% of the US workforce was set to retire over the next 5-10 years. In utilities and manufacturing, where turnover is high, this is becoming a huge issue. Imagine Bob, a senior maintenance technician with 35 years of experience, about to retire. When Bob walks out the door, so do many of his trade secrets in how to operate the facility. After speaking with several managers at these facilities, there is an eery since of panic approaching, where they are wondering how they will transfer Bob's knowledge to the younger generation before it's too late. Meanwhile, when hiring the younger generation, Bob continually has to hands on train these new hires with the same knowledge over and over again, just to watch them quit a year or so later. And this is where location based AR can show some real value. If Bob can capture his knowledge and place it next to the machines where it'll live forever, and be accessible in seconds from any mobile phone, it's as if Bob never actually left. Sort of like Obi-Wan Kenobi in the original Star Wars. New hires will be able to train themselves with the autonomy they so desire, while Bob can continue addressing the facilities larger issues. Anyway, I appreciate you reading, and I'll finish with this - we'd love to hear your thoughts, feedback, and or any questions you may have. The market and use cases for what we've built it quite vast, so narrowing it down has been one of the most challenging aspects. https://aircada.com/ August 15, 2022 at 10:13PM

Show HN: Site Visits a VR and screen-based installation series

cheap domain name registration
Show HN: Site Visits a VR and screen-based installation series Site Visits took its initial inspiration from Mozilla’s discontinued Tilt [0] dev tools feature. I remember using it more out of curiosity than as a practical tool over a decade ago. During a deep dive into what our [1] next work would be, Tilt came up again. We became inspired by the perspective it provided via the shape of DOM hierarchies across the web. Using this shape we started to find ways to merge the tangible structure of the site with aspects of the sites cultural impact. The project wants to create an alternate perspective on the web, by layering world-building elements on top of the 3D geometry of the site’s hierarchy. Trying to draw inspiration from the shape of this landscape, and let it influence the concept throughout. A deeper dive into the two current Site Visits is in the submitted link. --- The stripped down process for those interested: * A very simple browser plugin was created for Firefox that exports an untextured GLB file of the nested DOM hierarchy. * This is then brought into Blender, and combined with a full page screenshot to create the base landscape model. * Entirely in Blender and in a largely manual way all the world-building elements are created, explored and layered onto the landscape. * After the dust settles an optimized version of the model is created and used as an asset. * For VR we built out an experience via Unity or through stereoscopic 360 video, depending on the exhibition. I hope that this crowd finds this as an interesting take on the web, and am happy to answer any questions in the comments here! --- [0]: https://wiki.mozilla.org/Tilt_Project_Page [1]: https://instagram.com/loooop.studio https://boris.kourtoukov.com/site-visits-installation-series.html August 15, 2022 at 03:32AM

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://anysphere.co/anysphere-whitepaper.pdf ) describes our privacy and security model in detail — in short, we protect all of your data and metadata against everyone (even our own server). Our client is fully open source: https://github.com/anysphere/client . We deployed a small server to open up testing to everyone in the HN community. Instructions are here: https://gist.github.com/arvid220u/d960ca6483bf5f295498d9de99... . I can’t wait to hear your thoughts! https://gist.github.com/arvid220u/d960ca6483bf5f295498d9de990de7ef August 15, 2022 at 06:17AM

Show HN: Bog Gobbler Word Game

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: http://crosswordislandhopper.com/dailyChallenge 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://crosswordislandhopper.herokuapp.com/playGob August 13, 2022 at 10:41PM

cheap domain name registration
Show HN: DAW JSON Link I just released v3 of DAW JSON Link https://github.com/beached/daw_json_link , a C++ JSON library, that I am the author of. It's a C++ JSON library that prioritizes concrete data structures. It is fast, GB/s, and competitive with other libraries out there like simdjson. A brief list of things it supports are: * declaratively map json objects to C++ data structures * allows allocators to be provided and passes it to allocator aware types * can parse via a non-owning json_value that allows JSON Path like indices along with iteration of sub members * types to provide iteration over json arrays and use in C++ algorithms * JSON Lines/NDJSON support * The parser does not allocate at all, that is up to the resulting data structures, if needed. The memory usage is very minimal * Variants/Sum types are a priority and most expressions of them in JSON have easy mappings with a fallback to code if needed * JSON Schema output from mappings * Custom number types are supported(e.g Boost Multi-precision/GNU MP) * Serialization to most things is supported out of the box with the ability to easily add a new way. This includes, pointer, output iterators, span like types, strings/vectors/containers of byte like types, FILE ... An accompanying project https://github.com/beached/daw_json_link_describe that allows using Boost.Describe reflection like mappings with JSON Link * Lots of example code in tests folder and cookbook like documentation in the docs folder to see it in use. All the examples in documentation are part of the test suite too * Optionally allows for comments( # line comments and C-style // and /* /) Allows for trailing comma * constexpr https://github.com/beached/daw_json_link August 13, 2022 at 03:24AM

Show HN: Agency quality design and development for a very un-agency like price

cheap domain name registration
Show HN: Agency quality design and development for a very un-agency like price Howdy HN! Been working on a side project of mine for about a year called Gloutir. 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 needing landing page work / design services. There are a number of people doing stuff like this, but I do want to clarify that this is never going to be an "unlimited design" style subscription service. I've intentionally set a hard cap on the number of clients because it's simply impossible to accommodate more than a certain number of clients while keeping the quality of work where it needs to be. Anywho, curious what you all think and if you have any suggestions on how to improve. https://gloutir.com/ About me: full time designer and developer at an agency.

Show HN: Wordle but for Tweets

cheap domain name registration
Show HN: Wordle but for Tweets Hey HN I built this simple app that grabs four popular tweets from the last 24 hours and removes a word from each, so that the missing words spell out a phrase. It's the player's job to guess the missing words. A key motive for building this was that, to be honest, I was finding much of the news and social media dialogue quite depressing. I thought that if a wholesome or inspirational phrase can be built out of these (often tiresome) tweets, then there would be something nice about that. The stack included GCloud scheduler (for daily Tweet scraping and automatic puzzle generation), Supabase (which, by the way, is fantastic) and Next / Vercel. https://www.birdle.art/ August 12, 2022 at 02:04AM

Show HN: Releese – Music business management software After working in the music industry myself as an artist (Midsplit) and as a label manager / employee (ChillYourMind, Strange Fruits) I noticed that the music industry has very antiquated tools that are often expensive and rarely updated. I had the idea to build a platform that could streamline the entire releasing process of music, we nailed it down to metadata management, royalty splits, landing pages generation, distribution to major stores and royalty collection (publishing + neighboring) rights. After building this with a small team for 18 months, we finally managed to create our vision with a surprisingly functional product. Our cloud infrastructure is based on Google Cloud and our app is 98% Typescript (Thank you Github) I would love to know how someone in or outside the music industry feels about the platform. Hopefully we will help shape a better music industry! https://cloud.releese.io August 11, 2022 at 01:47AM

Show HN: PGPP (Pretty Good Phone Privacy) – a new type of mobile privacy service

cheap domain name registration
Show HN: PGPP (Pretty Good Phone Privacy) – a new type of mobile privacy service Hi, we're Barath and Paul. We co-founded INVISV to build Pretty Good Phone Privacy (PGPP) [ https://invisv.com/pgpp ], an app and service that provides mobile identifier privacy (IMSI) and Internet privacy (IP) so that neither we nor other providers learn your network identity. We've been thinking about how phones are tracking devices in disguise (at a few layers) and what we can do about it. But the problem is that mobile networks are hard to change, and existing companies are reluctant to change things. A couple years ago we had the idea that we could decouple your identity from your SIM (IMSI), so the mobile operator wouldn't know who you are but still provides you service. We did research, figured it out, and published it last year at Usenix Security. Then we took it to every mobile operator we could to see if they'd do it, but mostly got shrugs, confusion, or hostility. (We still hold out hope they'll change their minds.) So we decided we had to build and deploy it ourselves. And the mobile network is just the first part -- we also provide decoupled IP privacy (Relay) in PGPP via a partnership with Fastly, for when you're on WiFi or mobile data. The implementation is simple: for mobile privacy we decouple authentication from connectivity. Those are conflated today. We provide service using eSIMs (so you need an eSIM capable Android for this part). So we don't learn which eSIM your phone gets each time (your IMSI now changes periodically), we authenticate you with a cryptographic protocol (Chaum's blind signatures) that proves you should get a new eSIM but doesn't reveal your identity. Then you get mobile data service. This isn't something that exists today, despite the tracking/data collection that's happened both by third parties (SDRs / IMSI catchers) and operators themselves. It's like MAC randomization for mobile networks. We figured users would like better IP privacy too, so we used IETF MASQUE and collaborated with Fastly to provide relay service in PGPP as well. Relay service works on almost any Android device. This uses TLS to tunnel your traffic (which itself will usually be TLS encrypted, for almost all Web traffic today) through two hops and then to the rest of the Internet. The first hop is us -- we hide your IP but learn nothing of your traffic or where it's headed. The second hop is Fastly, who then connects you to the IP of the server you're trying to reach, but all they see is an INVISV IP trying to connect to some other IP. The site you're connecting to terminates your TLS stream but just sees it coming from Fastly. This is a beta and there are several things that aren't ideal. We don't have free plans because providing actual connectivity is pretty expensive. We know that data-only mobile service isn't for everyone (that's what our mobile plans provide -- no phone number). So we offer Relay service on its own for folks who want that. We also know eSIMs are not ideal either, so we'd like to generalize that down the road. We're focused on privacy, not just on mobile, and we'd love your feedback on the service and ideas about this and where to go next. Thanks!

Show HN: Build for any cloud with the same code

cheap domain name registration
Show HN: Build for any cloud with the same code We have been working on Multy, an open-source[1] tool that enables developers to deploy and switch to any cloud - AWS, Azure and GCP for now. We realized that, even when using Terraform, writing infrastructure code is very different for each cloud provider. This means changing clouds or deploying the same infrastructure in multiple clouds requires rewriting the same thing multiple times. And even though most core resources have the same functionality, developers need to learn a new provider and all its nuances when choosing a new cloud. This is why we built Multy. Multy is currently available as a Terraform provider. You can write cloud-agnostic code and then just choose which cloud you want to deploy to. Multy will then call the cloud provider APIs on your behalf. For example, the following Terraform code deploys a virtual network in AWS and can be easily changed to deploy to Azure or GCP: ``` resource "multy_virtual_network" "vn" { cloud = "aws" // or azure, or gcp name = "multy_vn" cidr_block = "10.0.0.0/16" location = "eu_west_1" } ``` Our goal is to expose any configuration that is common across all clouds, but there’s always specific features that are not available in all of them. For example, if you want a very specific AWS CPU for your Virtual Machine or use a region that is only available in GCP. To enable this, we implemented overrides [2] - a way to configure the underlying infrastructure for cloud-specific purposes. You can also mix other Terraform code that uses the cloud-specific providers with Multy. While this makes you somewhat locked in, having your 80% or 90% of your infrastructure cloud-agnostic is still very powerful. You can see more complex examples in our documentation - https://docs.multy.dev/examples/ . We’re still in early days and looking for feedback from other developers on our approach. Let us know what you think! [1] https://github.com/multycloud/multy [2] https://docs.multy.dev/overrides https://github.com/multycloud/multy August 8, 2022 at 05:57PM

Show HN: A link/news aggregator I am working on

cheap domain name registration
Show HN: A link/news aggregator I am working on Hello HN, I'm building omegapedia.com, a link/news aggregator that combines features of multiple other sites. I started building this site because I often found some features lacking in other websites. As example: You can format you text to be italic, red, blue or to be a spoiler. Comments are not threaded and don't include any voting feature. Omegapedia uses upvotes and downvotes for posts but shows them as separate numbers. I styled the page in darkmode but added an optional lightmode as well. I added "Trust-Points" and a leaderboard to show the 5 users with the most points. Other noteworthy features are: -Comment replies. -Flairs. -Adding a bio to your profile. -Mention users in comments. -Ability to add a email address to your account. -Forgot-my-password function. -Link posts. There is no need to add a email andress to your account and you will never be forced to. The site works on pc and mobile. The site is very lightweight because there are no CSS or JavaScript libaries that will have to be downloaded first. There are multiple ways to sort the posts and a way to show the recent comments so you can join a current discussion anytime. There is no register barrier and you will be automatically logged in a muted guest account. I am very interested in feedback and if you have any questions or comments please let me know, thank you! ======== Join me on omegapedia! https://omegapedia.com/showpost.php?id=467 https://omegapedia.com/index.php?sort_by=newest_first&page=1 August 5, 2022 at 10:25PM

Show HN: I created a browser automation tool

Show HN: I created a browser automation tool I created this tool a few months ago to automate some of my tasks. I use it to collect prices and files and to get notified when something changes on certain websites. The task runner uses Playwright. I'm not sure if it can be useful to anybody else besides me :) Any feedback is welcome. https://www.rocketride.io August 5, 2022 at 11:28AM

Show HN: Not8 – continuous product improvement platform

cheap domain name registration
Show HN: Not8 – continuous product improvement platform My co-founder and I are taking part in the acceleration program, and we're building not8 - a platform for team product reviews and user feedback collection. Right now we already have an MVP which is a Chrome extension that allows you to leave 'sticky notes' on live websites and share them in just one click. Our demo day is going to be in ~2 weeks, and we want to our user count to hit 1000 by that time. Actually, we want it so much that we are ready to offer our first 1000 users a forever free access to our product. Try out our extension now, and share a few notes with your team - I hope, you will love it. Here's how it works: https://www.loom.com/share/9e74f40086e741549e68740be236ee4b Here's where to download it: https://chrome.google.com/webstore/detail/not8/kdfppggcfpgdcdjcmfpmnfncifmdncfe August 5, 2022 at 05:40PM

Show HN: 3D Topography of Your GPS Track

cheap domain name registration
Show HN: 3D Topography of Your GPS Track As a hiker and (ski)mountaineer I've always been a bit disappointed of how most apps fail to properly depict the topography while analyzing GPS tracks. (I know that Strava offers some kind of 3D view by now, but I still wanted to build my own thing) That's why I started working on https://cubetrek.com It's still very experimental, but you can give it test-drive now. Any feedback appreciated. It essentially renders your GPS Track as a 3D model within the topography. As an example, here's the Bishorn, a 4000 m peak in Switzerland: https://cubetrek.com/view/5807 The front end is based on Babylon.js, D3.js, the back end is Spring Boot and Postgresql with PostGIS. There's a summary on how it works at the very bottom of the homepage. https://cubetrek.com August 5, 2022 at 07:27AM

Show HN: Score In URL, a sheet music editor that store everything in URL

cheap domain name registration
Show HN: Score In URL, a sheet music editor that store everything in URL I'm excited to publish my new project, [Score In URL]( https://powersnail.com/ScoreInUrl ), a simple, privacy-friendly, sheet music sharing service, where the entire content is encoded in the URL itself as a query parameter. It comes with a decent text editor, rendered score, and audio. The sheet music is notated with ABC Notation, rendered by abcjs. This project is heavily inspired by [Hashify]( https://hashify.me ), which encodes a markdown document into its URL. The code is here: https://github.com/PowerSnail/ScoreInUrl I made this with ViteJS and Tailwind CSS, and hosts it with GitHub Pages. I'm not proficient in front-end development at all, my past experience in this area being basically vanilla HTML/CSS, with a tiny bit of JS. This is in fact my first try at using any front-end framework. I sincerely welcome all feedback. The idea came to me when I tried to convey the idea of an exercise in a music forum. No forum I've used have native support for any form of sheet music. It's either typing "CDEFGAB", which isn't very readable and scales horribly for anything complex; or sharing an image, which is tedious because you have to open up an engraving software, export, and upload. And none of those approach has audio. You can read more about my thoughts [here]( https://powersnail.com/2022/score-in-url/ ). https://powersnail.com/ScoreInUrl/ August 5, 2022 at 06:49AM

Show HN: Penumbra, a perceptually optimized color palette based on natural light

cheap domain name registration
Show HN: Penumbra, a perceptually optimized color palette based on natural light For this palette, I used recent advances in color science, which made perceptual design more accessible, to choose a set of colors (mainly for syntax highlighting) that have uniform luminance for less visually uneven, fluidly readable code, but at the same time maximally distinguishable hue and chroma. The background colors are based on natural (sun-)light and shade for a more pleasing look than equally neutral greys. For much more detailed info, including the construction, check out the repository. There’s also already a (bare-bones) VSCode extension, linked in the repository, but it could admittedly use more informed distribution of colors over tokens, language specific highlighting and perhaps more opinionated use in UI elements. https://github.com/nealmckee/penumbra August 5, 2022 at 02:53AM
