Show HN: Red Goose – Convert your website to mobile app https://ift.tt/TDHJOor

Show HN: Red Goose – Convert your website to mobile app Hi HN! We're Sonica, Marvin, and Satie, and we are building Red Goose (https://goose.red). Red Goose is a web app to mobile app conversion engine that produces ready-to-publish apps for the app stores using GitHub repos. There was a discussion on HN a few weeks ago about how a developer shaved off almost half of their native app's code without losing functionality [1]. Our launch today is a direct outcome of that thread and, moreso, in the context of this comment [2] and this one [3]. Paraphrasing the context below: > "Fastmail is the only email/calendar app with a reasonable size (just 20MB)." Followed by: > "… EDIT: just realized the app is a web view. Sigh." As someone who has been into mobile app development since 2010, the comments above read like a punch to the gut. We grew up believing that the native experience was better than the web! It took a while to admit, but the web, it appears, has genuinely caught on. It has matured to a point where the four pillars of web development—HTML, CSS, JavaScript, and WebAssembly—are likely enough for universal distribution. We already host compute-heavy environments for graphic designers [4], video editors [5], and rich document editing [6] on the web. And there is still more capability [7] in the works, if you will. So the question we asked ourselves was: Could the modern web become the "native stack" of mobile app development? With Red Goose, we want developers to be able to do just that. Create web applications that double up as mobile apps for the app stores. But this isn't always easy. Historically, native mobile apps have differed from (outdone?) the mobile web in three broad ways: An app-specific design language, Smooth and fancy screen transitions and, Solving compute-heavy processes that scaled to millions of users. However, at the same time, building and maintaining native mobile apps is super expensive, and it requires hiring separate teams of experienced developers whose sole job is to focus on mobile APIs. Even with the newest alternatives like React Native, Flutter, Cordova, Xamarin, Ionic, or any other similar framework, there is a quantum increase in the amount of boilerplate code. Over time, as many of us have experienced in the industry, the web and native teams grow distant, leading to a less than optimum situation and bloat. Red Goose puts the webview back in the ring. This step alone removes all the duplicated code from the equation. Red Goose then offers an alternate strategy [8], using the webview as the main leverage over your web app. And solve for native experience in the following three ways: First—Intrinsic Design: we have built a new css framework called Toucaan [9] to tackle the gaps between mobile app design and mobile web. It allows the development of "app-like" interfaces using new css standards and the intrinsic qualities of the medium. Second—Screen Transitions and Animations: Not all apps need this, but smooth transitions and performant animations are already possible with the new web APIs. With a strongly cached webpage using a service worker (PWA) and a better understanding of initial containing blocks (ICBs) pertaining to your front end, one can easily take steps to take the experience to the next level. Third—Webassembly: The best thing about webassembly is that the wasm functions return immediately and synchronously. So one can easily offload compute-heavy transactions to a locally installed wasm utility and benefit from performance gains instantly on both web and mobile apps. It appears that many apps wouldn't need to sprinkle webassembly into the mix to reach the level of performance expected of mobile apps, and just caching with a service worker and an app-like layout would do the trick. Red Goose itself uses vanilla javascript and an experimental version of Toucaan for its frontend. Its backend is made with Node.js, Express, and MongoDB and is hosted on AWS within Docker. Our web-to-mobile app conversion pipeline uses NodeGit for app delivery, and the freshly minted mobile apps are written in Swift or Kotlin and shared directly over GitHub. We believe that the opportunity to reduce app development and distribution cost using the newfangled powers of the web is massive—we've already helped a few teams to cut back on their expenses by as much as 80%. At the same time, we're still early and would love to hear what you think about what we're building with Red Goose. We look forward to your comments and experiences, especially if you have been on this path before on your own. Thanks!

What a Year It Has Been! Let the Celebration of Transit Month Continue

What a Year It Has Been! Let the Celebration of Transit Month Continue
By Erin McMillan

Muni bus stopped at intersection and unloading passengers at bus stop.

49 Van Ness/Mission using the brand new bus rapid transit lanes on opening day in April.

During Transit Month this September, we’re continuing the celebration by looking back to more of the work we’ve done over the last year— some that has been less obvious to Muni customers, but critical to a well-functioning system and other work that is more front and center.

Fix It! Week and Continuing State of good Repair Work

Muni is an impressive transit system. Moving thousands of people on rail and buses every day takes a lot of coordination and a lot of work. Dealing with unique challenges like San Francisco’s geography and shifting travel patterns, we also have to deal with issues related to the Muni system’s age. Proper care and maintenance of a transit system many decades old takes strategic planning as regular maintenance needs to happen while continuing to provide service. Typically, regular Muni Metro maintenance work occurs each night after subway service hours, SFMTA maintenance crews work to maintain the tracks and equipment underground. On most nights, this gives crews only about two hours to get work done. This two-hour window sometimes isn’t enough to complete critical maintenance tasks, so beginning in April, we started Fix It! Week, a quarterly week of planned maintenance that occurs during extended, overnight shifts when trains aren’t in service.

This year Fix It! Week provided 63 total work hours during which several SFMTA teams completed over 2,000 hours of maintenance and inspections. On the busiest nights, the maintenance teams had up to 55 staff in the tunnel from West Portal to Embarcadero delivering safety improvements, station and tunnel enhancements, subway track and wayside equipment maintenance, and traction power upgrades.  

In addition to finding new and creative ways to maintain the system more efficiently, we also had to entirely reimagine the service network to accommodate changing travel patterns and in response to the pandemic. Over the past year alone we’ve increased Muni service multiple times as the impact of the pandemic has eased and we’ve slowly been able to hire new operators.

Trip patterns have changed over the last two years with a noticeable shift in San Francisco residents traveling neighborhood to neighborhood instead of the peak period downtown-centric travel pattern that was prevalent pre-pandemic. And we’ve adjusted. Service is slightly over-supplied so that there is capacity when it is needed. Anticipating how people will move in the future is difficult, but our service planning team is hard at work tracking ridership, customer feedback and operator availability to do our best to accommodate how folks want and need to move around the city. We are working to build back our ridership by providing high-quality, reliable service that people can count on.

Our response was the 2022 Muni Service Network which was developed through an extensive outreach process. Throughout the COVID-19 emergency and recovery, the SFMTA prioritized restoring service to these, and other neighborhoods identified in the Muni Service Equity Plan.

On the more visible side of our work, in April we started bus rapid transit (BRT) service on Van Ness Avenue as part of Muni’s Rapid Network, which prioritizes frequency and reliability for customers. Muni and Golden Gate Transit customers are already experiencing shorter travel times. With dedicated transit lanes in the middle of the street, enhanced traffic signals with Transit Signal Priority, the Van Ness BRT is the fastest way to travel north-south in this part of San Francisco, and riders are noticing. Since the BRT corridor opened on Van Ness Avenue in April, ridership on the 49 Van Ness/Mission has nearly doubled and is exceeding pre-pandemic ridership by 13%.

In other major capital and service news, last October service started on Geary in its new transit lanes after the completion of the Geary Rapid Project. Pre-pandemic, the combined Geary routes had one of the highest bus riderships in the country, with more than 56,000 daily customers relying on the 38 Geary and 38R Geary Rapid. As riders return, they are experiencing a faster, more reliable ride thanks to transit improvements like red colorization and dedicated transit lanes, bus stop optimization and signal retiming that were made along the three-mile stretch of Geary. These quick-build improvements alone resulted in 38R Geary Rapid travel time savings of up to 20%. 

And last but certainly not least, you may have heard we have officially announced the opening of Central Subway! Weekend service starts Saturday, November 19 and will give customers a chance to check out its four new stations, and also allow our operators and crews to work out any kinks while operating. We’re looking forward to welcoming you aboard!

Wishing you a Happy Transit Month!

Show HN: Restapp.io – SQL Data Modeling Tool in No/Low Code https://ift.tt/qNsYzZf

Show HN: Restapp.io – SQL Data Modeling Tool in No/Low Code Hey all! We've been working on RestApp V1 and this is our first time posting it on HN. It's an No/Low Code data modeling tool that enables you to build & maintain data pipelines with a visual programming interface. We don't store your data but we compute them through Apache Spark for query speed & efficiency. Here's some features: `Connectors: Connect to any source and destinations (DB, DWH and SaaS Applications). We currently support MongoDB, Snowflake, BigQuery, MySQL, MSSQL, SFTP (JSON, txt, csv, excel files supported), Hubspot, Stripe, GDrive (JSON, txt, csv, excel files supported). `Pipeline: Visual Programming Interface where you drag-and-drop SQL, NoSQL & Python functions instead of writing them to create a query and debug it easily. `Automation: You can automate your data pipeline (Job) through a scheduler. `Domain: Think of it like a workspace in which you can share securely your connectors and pipelines to specific users (colleagues, partners, clients...) We've designed this because as a data team member, we were writing a lot of long SQL queries with bad performances and we were getting headaches by debugging them. Now you can build, monitor and debug any kind of data pipelines with just Drag-and-drop built-in SQL functions to save you tremendous amount of time & effort. We're working on this continuously so we're keen to hear any feedback. Feature requests and critique are more than welcome. Try it out for free (30min of computing time offered each month): https://ift.tt/RmEJP8F The Getting Started docs are here for anyone who wants to check this out: https://ift.tt/v13eK0g and https://ift.tt/6zLMr2A... https://ift.tt/RmEJP8F September 28, 2022 at 06:14AM

Show HN: I wrote a database engine in TypeScript https://ift.tt/V0DOK4T

Show HN: I wrote a database engine in TypeScript Hi! I wanted to understand more about databases' internals so I wrote one from scratch. It has a T-SQL inspired syntax with support for functions and procedures. It can be used stand-alone as a SQL engine or with a server allowing for persistence and replication to other connected clients. Performance are nothing near sqlite of course but that's beside the point. It’s a small database engine that can run in a web app as a way to store session data, do small calculations on a web worker, store the document/data the user is editing or facilitate “multiplayer” feature by broadcasting the queries the web app is running. The server runs in a container for that specific document and shutdowns automatically after a set amount of minutes of inactivity. Why did I spend time on this? I am self taught and have been a software developer for about 20 years; moved to the UK for about 10 years, now in Spain and I'm still looking for the place I want to call home. My lack of diploma has never been an issue in Europe but if I want to discover other horizons, having one makes things easier. There's a process in France call "Validation des acquis" (Validation of knowledge) which allows anybody at whatever level to present to a panel of professionals and academics a request to validate one experience and deliver a diploma. That diploma is completely equivalent to a diploma delivered from a university. The experience must validate all of the targeted diploma curriculum so I thought digging into databases will help with that... Any questions, hate mail can be directed at alex at ixai.net. I'm also looking for a remote position as a Senior software developer https://ift.tt/PZrj2aD September 28, 2022 at 12:53PM

Show HN: Get conversational practice in over 20 languages by talking to an AI https://ift.tt/G1AORon

Show HN: Get conversational practice in over 20 languages by talking to an AI Hi everyone, Let me introduce you to Quazel, where we want to enable people to talk their way to fluency. We have all tried various language learning apps and tools, however, one aspect of language learning current services are really bad at is conversational practice. You might get a chat-like interface, but in the end, the conversation partner will only respond with a predefined "if the users say X I say Y". With Quazel that's completely different. In completely dynamic and unscripted conversation you can talk about pretty much anything you want. For example, you can try ordering food at a restaurant and even hold a philosophical discussion with Socrates. Additionally, you can analyze the grammar of your responses or use hints to help you out when you get stuck. We want to change how languages are learned from a grammar-centric approach to a more natural, conversation-focused one. https://ift.tt/rYU6zo7 September 27, 2022 at 05:18AM

Show HN: Media Hoarder – media front end for data hoarders and movie lovers Here's a video showcasing Media Hoarder's features: https://www.youtube.com/watch?v=TGkU9e1l8HU As we're on hackernews I wouldn't go much into the features of Media Hoarder with this post (see the video above for that). I'd rather like to comment on the DX. I'm a long-time lurker here on HN and in 2019 I felt the urge to develop my own take on a media center application. Media Hoarder was already usable after a few days of development and after one year it had 90% of the features I wished for myself but was not exactly ready for a release to the public. So, for this project the last 10% took another two years :) During the development I read a lot about the "ship fast" mindset which I obviously did not adopt. I could never live with a publicly released version that does not completely show what I had in mind with the app. And yeah, currently my focus is not to get external feedback as fast as possible but to create and release a product as v1.0.0 that I envisioned and use myself. The tech-stack is: - Electron - Vue.js with Vuetify - SQLite this way the app runs on Win/Linux/Mac and can be entirely developed with web technologies - which to me is a great plus regarding development speed. Mind you, Media Hoarder is developed during the free-time of a father of two young kids :D Anyways, I'm really glad it's out there. Personally, I use it every day and I hope, some of you may find it useful or would like to contribute. Please feel free to discuss features, development and sideproject-y things, I'm really curious :) Media Hoarder Website: https://ift.tt/nZ98pQU Blog post "Why Media Hoarder?": https://ift.tt/7mOLeBa GitHub project: https://ift.tt/RHifOtE cheers -- MK2k https://ift.tt/nZ98pQU September 23, 2022 at 10:20AM

Show HN: Copy link to highlight alternative for Chrome with multiple highlights Hi HN! I made a Chrome extension called Save Link to Highlight. It makes it easy to share multiple highlights on a page without any hassles. It uses the same built-in technology in Chrome as Copy link to highlight. So, the link you share will highlight text on a page in most browsers without 3rd party tools. Ex. https://ift.tt/ikhzAsR It's free! No account or signup needed. Some everyday use cases • Share an article with a friend that also has the parts you found most interesting highlighted. • A teacher can share key points they highlighted for students on a Wikipedia page. https://ift.tt/e103R2V September 22, 2022 at 08:34AM

Show HN: The simplest drum pattern composing algorithm I could come up with https://ift.tt/Wiu7m19

Show HN: The simplest drum pattern composing algorithm I could come up with Hi there, my name is Jay. Making music and writing software have probably been the two biggest pleasures of my life -only after my family. My team and I recently started a long journey of trying to completely change the way people create music, and as it usually happens with any long journey, it all starts with small steps. One of those small steps was to build https://drummy.io, or "Dummy Drums," a very simple yet useful drum machine that stores the entire drum pattern in the hashtag of the URL. There is no backend. Fully served by a CDN. If you wanna learn how to build your own drum machine in Javascript using the WebAudioAPI, here's an amazing read: "A tale of Two Clocks." (https://ift.tt/zjhkZUY). Also, check Howler.js (https://howlerjs.com/), a rock-solid library with a great community. Anyway, not long ago I noticed the dummy drums site hasn't been getting much traction, but I think I figured out why. Most of the new users are getting frustrated because it is very easy to get stuck trying to come up with a fresh drum pattern, and so https://twitter.com/DrummyBot was born! A function written in less than an hour that comes up with pretty decent rhythms. While not in any specific style, and no ability to choose settings or tune it, it may still be a great kickstarter for that new beat you just can't seem to find. It is like the opposite of a fancy AI that seems to be so hot these days. If you think DrummyBot can help you get inspired, just follow it on Twitter. The bot publishes a new pattern every hour, and even tries to give it a name using PHP's Faker library. You can also simply go to https://drummy.io and use the magic wand button to get a fresh pattern with each click! The function is totally randomized, you will never get the same pattern twice, and customizing literally requires just a few seconds. I hope you like it, and of course, all feedback is gladly welcome! September 21, 2022 at 08:33AM

I used the Python SDK for OpenZiti (overlay networking platform) to create a GitHub Action that sends the webhook to my private server via overlay instead of via the open internet.

Show HN: Hurl, test APIs with plain text and libcurl https://ift.tt/n6l5Pbg

Show HN: Hurl, test APIs with plain text and libcurl Hi, We're happy to release a new version of Hurl [1]. Hurl is a command line tool powered by curl, that runs HTTP requests defined in a simple plain text format: # Get home: GET https://example.org HTTP/1.1 200 [Captures] csrf_token: xpath "string(//meta[@name='_csrf_token']/@content)" # Do login! POST https://ift.tt/CJzHIrO X-CSRF-TOKEN: HTTP/1.1 302 Hurl can be used to get data like curl, or as an integration testing tool for JSON/XML HTTP apis / HTML content. Requests can be chained, and one can add asserts on response headers, cookies and body. For instance: GET https://ift.tt/m0NjUrw screencapability: low HTTP/1.1 200 [Asserts] jsonpath "$.validated" == true jsonpath "$.userInfo.lastName" == "Herbert" jsonpath "$.hasDevice" == false jsonpath "$.links" count == 12 jsonpath "$.order" matches /^order-\d{8}$/ You can see more samples in the documentation [2]. We've designed Hurl to be easily integrated in CI/CD (GitHub, GitLab), and its text format can be used as a documentation, commited in a repo etc... It's a single binary written in Rust, that is powered by libcurl under the hood, for a fast CLI tool for both devops and developers. In this new version, we've added the following improvements: - verbose output: add more color to Hurl --verbose output, and also added --very-verbose option to output request and response bodies - request options: command-line options such as --location (follow HTTP redirection), --verbose, --insecure etc... can now be applied to a particular request with an [Options] sections - and more, see here for a quick tout of 1.7.0 [3] [1] https://ift.tt/xBoG1Rw [2] https://ift.tt/AjSbzxX [3] https://ift.tt/oG9yEQz Previous Show HN < https://news.ycombinator.com/item?id=28758226 > and < https://news.ycombinator.com/item?id=25655737 > https://ift.tt/xBoG1Rw September 21, 2022 at 04:43AM

Show HN: TaskTXT, plain text task-timing notepad https://ift.tt/y5tlAYO

Show HN: TaskTXT, plain text task-timing notepad I built TaskTXT.com based on my experience timing my tasks. I found that committing to a task before I start helps with my focus, and guessing how long it will take, then timing it prevents me from wanting to give in to distractions because I'm "on the clock". Video Overview: https://www.youtube.com/watch?v=HOYO0c_D6w0 There's also a Mac app which you can download here: https://ift.tt/9v4FK6j Video overview of the Mac app: https://www.youtube.com/watch?v=qMs-V5v5gZY But I didn't want the tool to be distracting, so its based on plain text. That means the UI is very familiar and you can use it for generic notes in any structure you like. When you work in TaskTXT you are working directly on its data format, I made a video about this concept here: https://www.youtube.com/watch?v=kZdBgVZn5NI I think this tool is uniquely suited for programmers, so I'd be interested to hear any feedback about the product, or its viability as a business. https://tasktxt.com/ September 20, 2022 at 02:25PM

Show HN: VoiceLine – Work with STT voice messages in your Chrome Browser Hey all, I’m super happy to share the official launch of the VoiceLine Chrome Extension that my colleagues and I have been building over the last year. It allows you to record, share, and play voice notes within any browser-based application. We’re using an STT model to transcribe your notes into what we call a VoiceLine, a hybrid audio-text snippet, to address the problems of conventional voice messaging. Our vision is to introduce a new category of professional voice communication by building our service as a layer, not yet another instant messenger like Slack or MS teams. It works within any tool like Jira, GitHub, G Suite, Notion, … you name it. Would love to get some feedback and support, we’re also on producthunt today: https://ift.tt/f0pD6No https://ift.tt/Gle9UTr September 20, 2022 at 10:00AM

Show HN: Confabulists – “Substack for Fiction” https://ift.tt/q0zbCsQ

Show HN: Confabulists – “Substack for Fiction” Hey HN, I am launching a newsletter tool for those who write fiction: https://ift.tt/YXlmVLy This is the page focusing on convincing writers to sign up. It is a two-sided marketplace (writers and readers), but since I am just starting, there are no published writers yet -- who write in English at least. So if you write fiction of any genre, professionally or not, I invite you to try it. Confabulists is the culmination of several personal experiences. First, I am trying to start a new career as a fiction writer. Which is hard. It is one type of content or art creation still heavily controlled by gatekeepers -- book editors. Amazon created a good option for self-publishing, but since it is not "media", it does not offer much opportunity for growing an audience. Or retain it, as there is no guarantee that a reader of one of your books will even know about the release of your latest one. In contrast, creative people that work with visual arts have TikTok, Instagram, YouTube, Vimeo, Twitch. Audio creators have the video platforms as well, but also Spotify, Deezer, Bandcamp. And finally, creators of the written word benefited from the resurgence of newsletters. Substack took it to a new level, attracting great thinkers and journalists with a good model for these professionals to earn their money a bit more directly. I am a big fan of Substack. I created my newsletter there early on and tried three times to get a job there as a software developer (always politely rejected because they don't hire globally remote). But, despite a few recent efforts, I don't think Substack is a good place for fiction writers. The main thing is that writing fiction takes time. It's hard to post new fiction weekly. And fiction is about past, completed works. Something that the current media landscape, newsletter tools included, strongly incentive against. You should always be creating new content. A new subscriber only gets your future work. Past texts are for those with a neck for digital archeology. That's why I created Confabulists. The main difference in the tool is that new readers, when they subscribe to an author, choose a book and start getting that book in installments from the first chapter. Completed books matter. "Old" fiction attracts new readers. Another experience that led me to Confabulists was a free site that I built and launched in a Show HN [0] a couple of years ago: https://ift.tt/uekWbnE It was built for reading of public-domain classics in installments delivered by email. Just like Confabulists is for new authors. It got some traction here on HN and proved to me that people really engage in reading fiction in their email inboxes. At this peak, right after the Show HN, it had 800 active subscribers receiving installments from a book. Today, after two years, with zero marketing effort (I never even posted again on social media or anywhere), there are almost 200 active subscribers. No available book lasts that long in weekly installments, so these are either people who subscribed to a new book or new subscribers that found Serial Literature through word of mouth. For a zero-marketing effort, I consider this good retention and evidence that reading fiction through email has its audience. I am solo on this. From idea to coding, to copy and design -- this last one with AI help with the illustrations. As a Brazilian and wanting to publish my work on it, I created it initially in Portuguese [1]. It was great for the beta reading of my first novel. And useful to find and fix some bugs and iterate the product until I had a solid solution. I think it is good enough to try to reach more people with its version in English. I hope some fiction writers on HN find it useful too. Thanks!

Show HN: Off-site, encrypted backups for $1/TB/month at 99.999999999% durability Hi, most people (hopefully) have local backups. However, when that backup fails, it is good to have a backup stored somewhere off-site. In the old days you would ship physical drives/tapes, which is cumbersome, costly, and slow. With fast upload speeds, it is now possible to upload your data to the cloud. I have found S3 Glacier Deep Archive to be a great solution for this: - It is very cheap ($1/TB/month for US region) - Very reliable (99.999999999% data durability, data spread over 3 Availability Zones) However, usability out of the box is not that great, I'm not aware of any automated backup solution for Deep Archive.

Show HN: Rentaflop – Render your Blender projects without sacrificing quality https://ift.tt/bL92tmw

Show HN: Rentaflop – Render your Blender projects without sacrificing quality Hi HN, My name is David Sokol, and I'm the founder of rentaflop (https://rentaflop.com). We're a crowdsourced render farm aimed at making Blender rendering fast and affordable. If you've used Blender, then I'm sure you've experienced the pain of waiting around for your animations to render. You've probably even had to sacrifice the quality of your work to reduce your render times. I've been there too. If you're like me, then you're also disappointed with the alternative solutions: spending thousands of dollars on graphics cards or using prohibitively expensive cloud render farms to get fast render times. Our solution to this dilemma is to leverage low opportunity cost hardware from around the world to allow Blender artists to render their projects quickly, affordably, and without compromising on quality. Since most graphics card owners aren't utilizing their hardware to do valuable work 24/7, we provide them with a way to make money without lifting a finger, while lowering the cost curve for 3D rendering. We're currently doing a public beta. If you'd like to try us, check out our site (https://rentaflop.com) and render your Blender project quickly and affordably! If you're a graphics card owner who wants to help Blender artists while earning money, reach out to support@rentaflop.com and we'll help you get set up. We posted about our private beta on HN a few weeks ago. If you'd like, you can check out the discussion here (https://ift.tt/u63gDhp). Please leave a comment below, we'd love to hear your thoughts :) September 14, 2022 at 11:34AM

Show HN: StackAid – fund 100s of open source dependencies with one subscription https://ift.tt/5JHRn9p

Show HN: StackAid – fund 100s of open source dependencies with one subscription We strongly believe working on open source software should be a viable source of income for many more developers. Unfortunately, the following barriers limit the extent of open source funding: - Only a small fraction of open source projects are funded, and most money goes to a few notable projects. - Each project has to market is self to get significant funding. - Large corporate donations provide the bulk of the funding, making it unreliable and unattainable for many. - Finding and supporting each of your dependencies is a cumbersome task. Which ones, how much, and on which platforms? So we built StackAid, a service that automatically discovers and funds your direct and indirect (second order) open source dependencies with a monthly subscription. StackAid is early and has a unique allocation model, so we're working with supporters and open source projects to validate the experience further. We're matching subscriptions up to $100/month during the beta. https://www.stackaid.us September 14, 2022 at 10:35AM

Show HN: Fide – Crunchbase for Web3 Projects and People https://ift.tt/V5IH0F8

Show HN: Fide – Crunchbase for Web3 Projects and People Hi HN! I’m Chris, Co-founder of Fide. When contracting for Celsius in 2019, a recently bankrupt crypto-lending platform, I quickly observed how important it was for every Web3 company to establish credibility and trust in a high-risk industry where fraud and scams are becoming increasingly common. As I continued to invest and build in the space, it became clear that existing tools are still not enough to effectively evaluate credibility. Common issues that keep coming up include: 1. Repeat scammers are rarely held accountable 2. Anonymous contributors can’t easily establish credibility 3. Project and contributor success metrics are mostly based on historic financial performance We built Fide to help users verify web3 credibility and only invest in projects and teams they can trust. We’re still adding features and projects but would welcome any feedback as we continue building! https://www.fide.id/ September 13, 2022 at 11:08PM

Show HN: ViruSaas – Virus Checks as a Service https://ift.tt/DkiIPHl

Show HN: ViruSaas – Virus Checks as a Service Hi all, here is a side project I've just launched which might come in handy for certain situations. It's a very simple and free "do one thing and do it well" online service with exactly one feature: you upload a file, and it tells you — based on a ClamAV check — if that file contains a virus or not. I'm not having any ambitious plans with this project, but thanks to very low operational costs, I thought I can as well put it out there and keep it alive — maybe it's even useful for some people every now and then (just today, one of my coworkers forwarded me a fishy-looking email with an attachment, and using virusaas.com turned out to be the least painful way to do this kind of one-off check for a virus). I've also released the source code of the web app under GPLv3 at https://ift.tt/0ENcFWM , although it's not as polished as it could be (no tests, for example — but see above, no ambitious plans). The main reason to do the project was to follow through with my own tutorial at https://ift.tt/82R6vyr... , which worked out quite nicely. https://ift.tt/AWxZ8Dk September 14, 2022 at 07:19AM

Show HN: Quake VR – Quake (1996) as a first-class PCVR experience https://ift.tt/DgxIP0A

Show HN: Quake VR – Quake (1996) as a first-class PCVR experience Hello HN! I am proud to show you Quake VR, a "labor of love" one-man project that I started back in 2020 with the goal of turning Quake -- the timeless classic from 1996 -- into a first-class PCVR experience. --- > What do you mean by "first-class"? There are many mods out there that enable older games to be played in VR, however, not much thought is put into VR-unique mechanics or in making the experience feel seamless. While I do enjoy reliving nostalgic classics in VR (and thank the modders for their efforts), it does feel weird having to use a keyboard+mouse setup for a VR game, or -- even with motion controls -- not being able to physically interact with the game's world, or having a gun glued to one of my hands. With Quake VR, I tried my best to make the game feel like an experienced designed from the ground up for VR. A video is worth a thousand words: https://www.youtube.com/watch?v=MBoI16z8Nxg --- As you can see from the video above, Quake VR provides a plethora of VR-specific features, including: - Virtual in-game hands with finger tracking - Dual-wield weapons or hold a weapon with two hands - Physical melee combat, including throwing weapons and headbutts - Weapon models with ironsights - Collisions between the player's hands and the environment - Holster system with virtual torso For a complete list of features, check out the README: https://ift.tt/f26C7Gr I love VR-unique interactions, and I try to find opportunities to add more. As an example, I recently added "flick reloading" to the SSG -- see it in action here: https://www.youtube.com/watch?v=uV8gbDvNYAM . Here is an older trailer showcasing features like dual-wielding, holsters, and the grappling hook: https://www.youtube.com/watch?v=c_ctxSqs6gA --- Quake VR is written in modern C++ and it's completely free and open-source : https://ift.tt/aCjB7Ot . If you have any question about the game or any implementation detail, feel free to ask here on or the official Discord server ( https://ift.tt/PDhYsra ). --- If you have a PCVR headset, I sincerely hope you will check out the game and let me know what you think! The game is available on a "pay what you wish" model here: https://quakepcvr.com/ - Make sure you closely follow the installation guide ( https://ift.tt/OJYVGrs )! Cheers, Vittorio --- FAQ: > Is this project related to the Quake ports available for the Meta Quest? * No, this project is separate from those. It uses a different engine and it was developed by me, Vittorio Romeo, with some very appreciated contributions by community members (https://ift.tt/CnByeWp). > Why is Quake VR not available on Steam? * I've tried really, *really* hard to release it on Steam as a free community mod. However, that requires permission from the owners of the Quake IP. I have spent countless hours trying to communicate with id Software, Bethesda, Microsoft, never receiving *any* sort of response. I've even tried directly contacting employees, who kindly forwarded my request to the legal team, to no avail: zero answers whatsoever. I have not given up -- if you know someone that can help, please let me know! > Is Quake VR compatible with existing Quake mods or existing Quake servers? * No, Quake VR uses a custom protocol and engine in order to deliver first-class VR features. It is possible to adapt mods to work with Quake VR -- I have done that for the official expansions and some popular mods. > How can I support the Quake VR project? * Quake VR is FOSS, however I am more than happy to accept donations for my efforts. PayPal (https://ift.tt/pg8P34H) works best for me, alternatively consider purchasing "Open Hexagon" (https://ift.tt/eOs41BI), my first commercial game on Steam. https://ift.tt/Ca68ZIl September 11, 2022 at 12:27AM

Show HN: Ringer – Get and provide expert help on Open Source Software https://ift.tt/Y5hWd1M

Show HN: Ringer – Get and provide expert help on Open Source Software Hello HN, Over the past few months we've been building Ringer, an Experts Marketplace focussed on Open Source Software. We want to help make Open Source more sustainable and believe that we can be a part of making that happen. We're approaching this from the perspective of the individual developer - if you contribute to OSS then you can register instantly with your GitHub account and list yourself to provide paid support, knowledge and help for the repositories that you contribute to. We only allow those who we can prove contribute to repositories to list themselves as experts, and show details of contribution history for the experts in the system so that customers can see exactly how the experts can help. We process payments to over 100 different countries via Stripe, and handle all of the paperwork to make the process as frictionless as possible, including 1099s for US based experts. We're building out tools to improve the developer experience at the moment, and have started to work with customers to design a process that allows them to access expertise quickly whilst working within the constraints of an enterprise environment. For the past 3 or so weeks we have been in an Alpha stage, so this is our Beta launch - we are really open to fresh ideas and opinions. From day 1 I have said to every developer that I have spoken to that whether you love the idea or hate it, all I want to know is why and what we can do better - so HN, please tell me what you think and want it to be! https://ift.tt/k5gtV19 September 8, 2022 at 08:45AM

Show HN: Visualizing Startup Management with Timeline Hi everyone, We are building a web app for startup founders. Like Jira, Notion, or ClickUp, we support task management. However, we think time is more important than the tasks, because startups need to build product fast, and shift focus fast. Therefore, we built one universal timeline to help you easily manage tasks, clients, projects and deadlines, so you can directly compare the important dates from all your departments and find one which matter the most now. We also support task auto scheduling, so when you shift your team to a new direction, you just need to change the priority, and we help you reschedule all the tasks in you team. So you don't need to manually updating the start date or the end date fields in Jira, Notion, or ClickUp. You may have heard of Motion ( https://ift.tt/uEexQWK ), which also supports task auto scheduling. Unlike it, our app focuses on serving the startup teams and innovation teams. So we also have the goal tracking feature to help startups meet the annual growth goal from every day. We are actively learning, and we want to build something people want. We are looking for any feedback from you. Best, Zhe https://collow.io/ September 7, 2022 at 11:35PM

Show HN: Depot – fast, remote Docker container builds https://ift.tt/XUaGPyT

Show HN: Depot – fast, remote Docker container builds Hey HN! We’re Kyle and Jacob and we are excited to show you Depot ( https://depot.dev ) and get your feedback! Depot is a hosted Docker container build service, providing fully managed remote builds from CI and from your terminal. We support both Intel and Arm builds natively. As application and platform engineers, we have experienced the challenge of keeping Docker container build times fast. From optimizing and reoptimizing Dockerfiles, to implementing layer caching in CI, to running & maintaining custom runners for multi-platform images. Still today, there are limitations with the available tools. CI runners are ephemeral, and saving and loading cache tarballs is slow. CI providers are resource constrained, with limited CPUs and disk space to dedicate to fast builds. And with the increasing popularity of Arm devices like M1, Graviton, etc, building multi-platform images requires slow emulation or self-hosted infrastructure. We created Depot to directly address those limitations. Depot provides managed VMs running BuildKit, the backing build engine for Docker. Each VM includes 4 CPUs, 8GB of memory, and a persistent 50GB SSD cache disk. We launch both native Intel and native Arm machines, on Fly.io for Intel builds and AWS for Arm. We have built a depot CLI that embeds the Docker buildx build library, implementing the same CLI flags, so developers can send their builds to Depot VMs just by replacing `docker buildx build` with `depot build`. We also have a depot/build-push-action GitHub Action that can be swapped for docker/build-push-action in CI. The combination of native CPUs, fast networks, and persistent disks significantly lowers build time — we’ve seen speedups of 2-3x on optimized projects, and as much as a 12x speedup with some of our customers. We believe that today we are the only hosted CI or build service offering the ability to natively build multi-platform Docker images (--platform linux/amd64,linux/arm64) without emulation. We are still early though, and would love your feedback. You can sign up without a credit card at https://ift.tt/QxpjOX8 to access a free project with thirty days of unlimited build minutes to try it out. https://depot.dev September 6, 2022 at 11:04AM

Show HN: VoxelChain – An Experimental Voxel Engine https://ift.tt/A2dwhSy

Show HN: VoxelChain – An Experimental Voxel Engine VoxelChain is an experimental tool to create voxel worlds in the browser. The lighting is fully ray traced in real-time and there is powerful cellular-automata based programming system, which allows to create complex digital circuits and model the behaviour of voxels (behaviour such as falling sand or water). Technology wise, I'm using WebGL2 for the rendering and the simulation is coded in C89 and gets compiled to WebAssembly (with multi-threading) using Clang. The simulation is basically a custom cellular automaton and is fully parallelized. Once WebGPU is released, I'm planning to run the simulation on the GPU, instead of the CPU, which will give a massive speed up. I've been working on this project full-time for over a year now, and finally came to the point of realising a public version of it to play with. There is already some really cool stuff that the community has built, and it's super fun to see how everything evolves!

Show HN: I made Scrabble with modified rules https://ift.tt/ipzOvY2

Show HN: I made Scrabble with modified rules Crapple is my take on "improved" Scrabble rules... obviously that is subjective, I'm not even sure I agree with it. You and your opponent share a rack of letters, and vowels are only obtained by opting to deduct a configurable amount of points from your score to receive a random vowel tile. Additionally, there is an alternate board layout with some new tile multipliers. This is an old project but I never posted it, so I thought what the hey, I am curious to hear what your guys' thoughts are on these rules. It's an old dead project so you can't hurt my feelings. Thanks! You can play it now against the computer in your browser (no signup required, but an account lets you create and play games against other humans). The Android app is the better version only because the AI will run on a seperate thread (in the browser version you might see a hiccup while it runs), and because Unity WebGL doesn't export retina-sized graphics (ie graphics may look less than sharp on your mobile device). (Note: I linked the landing page instead of the direct link to play in case you are on mobile and want to avoid a largish download. Direct link to play in the browser is here: https://ift.tt/tuC1v7b ) --- Some more details for anyone still reading... It's your basic LAMP stack on AWS, with Laravel for the web framework and Unity (2017) for the client. The dictionary is stored as a DAWG. When you play a word, instead of giving you the dictionary definition, I wanted to do something different like provide a paragraph from a book that the word was used in. You can click the book icon to get some of those, I was scraping books in the public domain but gave up after a while when I was getting diminishing returns for words I lacked paragraphs for (if you try it you will likely see a lot of Moby Dick paragraphs as I never randomized it either). The AI was based on the scrabble AI algorithm (I think it was this, but can't remember now, https://ift.tt/yoBqhKc... ). Since Crapple has modified rules, due the possibility of "buying" vowels on your turn, there is set of _potential_ playable words. The Crapple AI ranks each word based on the cost of the vowels needed with their probability of obtaining the needed vowels. The AI is not very intelligent, the difference between the 3 provided computer opponents is just the average word score they will play. If I had worked on this any longer I could have extended this to let them take into account what words/scores they may be setting you up for with their play, and other ideas. Each player's avatar is consistent, but uniquely generated for them. I didn't want to have every using the same boring default avatar, but didn't want the hassles of letting people upload their own, so I went with a version of this idea: https://ift.tt/tBQN5iq https://crapple.mobi/ September 3, 2022 at 04:15PM

Show HN: Alumina Programming Language https://news.ycombinator.com/item?id=32702812

Show HN: Alumina Programming Language Alumina is a programming language I have been working on for a while. Alumina may be for you if you like the control that C gives you but miss goodies from higher level programming languages. It is mostly for fun and exercise in language design, I don't have any grand aspirations for it. It is however, by this time, a usable general-purpose language. Alumina borrows (zing) heavily from Rust, except for its raison d'être (memory safety). Syntax is a blatant rip-off of Rust, but so is the standard library scope and structure. Alumina bootstrap compiler currently compiles to ugly C, but a self-hosted compiler is early stages that will target LLVM as backend. If that sounds interesting, give it a try. I appreciate any feedback! Standard library documentation: https://ift.tt/qGoc02Y Online compiler playground: https://ift.tt/ZYogRfB https://ift.tt/0jlzHRW September 3, 2022 at 11:32AM

Show HN: Stop writing Excel like it's assembly https://ift.tt/3Yhio8V

Show HN: Stop writing Excel like it's assembly I suck at excel - https://www.youtube.com/watch?v=0nbkaYsR94c I would write the equivalent of: /* Tax rate */ var b1 = 50%; /* Salary */ var b2 = 120000; var b3 = b1 * b2; When excel lets you write: var tax_rate = 50%; var salary = 120000; var b3 = tax_rate * salary; I just didn't know any better. This class of problem can be solved by a linter and auto-formatter to automatically detect and use excel best practices. Which also helps you learn best practices. Stop reading and writing excel like it's assembly. Upgrade your excel to the modern era. If you have suggestions or recommendations I'd love to hear them. I just saw the above video linked on HN and thought I can solve this! The current version is extremely simple/naïve/ugly. https://ift.tt/t1P97CR September 3, 2022 at 10:30AM

Show HN: I'm building an open-source Amazon https://ift.tt/ty8WKmk

Show HN: I'm building an open-source Amazon A couple of years ago, I had an interesting idea. What if there was a marketplace where all the underlying tech was open-source? The order management system, the storefront, customer support, etc. The marketplace would simply connect to the seller’s infra instead of locking them in. If, for some reason, the seller is removed from the marketplace, their software stays with them and they can continue accepting orders directly. This model can be used to disrupt any marketplace from AirBNB to UberEats: building tech for home renters and restaurants and later, leveraging that to build a competing marketplace. In 2019, I started building the first piece, Openship, an order management system that lets you source orders and fulfill them from anywhere. Now that that’s in stable release, next up is Openfront (an e-commerce platform for storefronts) and Opensupport (ticketing software for customer support). Together, they provide the staples for any modern business: sales, fulfillment, support. Let me know what you guys think of the idea and if you see any potential pitfalls. https://openship.org/ September 2, 2022 at 09:19AM

Let’s Celebrate During Transit Month this September

Let’s Celebrate During Transit Month this September
By Erin McMillan

Muni bus traveling in the transit lane on Geary Boulevard.

The 38R Geary Rapid reaping the benefits of the Temporary Emergency Transit Lane on Geary Boulevard.

Today marks the start of Transit Month! Every year we look forward to celebrating Transit Month by looking back at all the successes of the previous year—and also by thinking of our upcoming opportunities to continue to improve Muni.

Over the past year, we have made a series of improvements through our Muni Forward program that reduced travel times, wait times and crowding:  

  • Reduced travel time by up to 31% on key bus routes as part of  the Temporary Emergency Transit Lanes program, giving more riders the benefit of the transit lanes faster.  
    • 10 miles of transit lanes were made permanent benefitting the T Third, 1 California, 14 Mission, 19 Polk, 27 Bryant, 38 Geary, 43 Masonic and the 44 O’Shaughnessy. This cool animation shows how transit priority is improving Muni travel times citywide!
    • As part of the TETL program, last October, the San Francisco Transit Riders gave us an award to honor the “Fastest Expansion of Transit Lanes in San Francisco History.”
  • Started bus rapid transit service on Van Ness Avenue, with initial weekday travel time savings of up to 35% on northbound trips, equating to 9 minutes a trip. And southbound, up to 22% travel time savings, or 5 minutes on a trip.   
  • Completed the Geary Rapid Project, which improved one of the city’s busiest corridors with much-needed safety improvements and more reliable bus service for the 38 Geary and 38R Geary Rapid’s over 56,000 daily customers.
  • Installed the one of a kind urban high-occupancy vehicle (HOV) lanes along Park Presidio Boulevard and Lombard Street that expands the capacity of those streets to carry more people with the same number of lanes.  
  • Reduced collisions on California Street by 64% for all modes and 89% for transit as measured in the evaluation of the California Street Safety Project.
  • Began implementing spot improvements to the top ten corridors where Muni experiences delay as part of the Transit Delay Hot Spots Program. The improvements feel small but benefit the full route.
  • Continued construction of transit reliability improvements on 19th Avenue, Taraval Street, 16th Street, Mission Street in SoMa, and along the 27 Bryant in the Tenderloin.

To see locations where Muni Forward improvements have been made across the city, check out this interactive Photo Map. Whether targeted spot locations, or along major corridors, improvements to the Muni network benefits everyone.

And looking ahead, we have started planning for Muni Forward improvements to the J Church, K Ingleside, M Ocean View, N Judah, 29 Sunset and 38 Geary. For some Muni lines, we hope to implement quick-build improvements as soon as next year! To support this work, and other work across the SFMTA, we were recently awarded $116 million from the California State Transportation Agency of the Transit and Intercity Rail Capital Program (TIRCP). Be on the lookout for more improvements coming soon!

Of course, that’s not all we’re doing to improve transit: we’ve been restoring service across the system, rehabilitating our subway system, and we’re putting the final touches on the Central Subway. Read more about our progress on enhancing transit service and safety in San Francisco.

Happy Transit Month, Muni riders! And for more information on the San Francisco Transit Riders Ride Along & Rally Wednesday, September 7  from 8 am - 10 am, please visit San Francisco Ride Along & Rally.

Show HN: Open-source infra for building embedded data pipelines https://ift.tt/PmZbtdW

Show HN: Open-source infra for building embedded data pipelines Hey HN! We are building *open source infrastructure for deploying customer-facing data pipelines.* Here’s our repo https://ift.tt/rG2XR6C and website https://pipebird.com/ . Pipebird is designed to enable companies that generate important data to offer secure data pushes to their customers’ warehouses, directly from their products. Our team was previously building in fintech, where we heard from many of our peers that their customers wanted data pushed directly to their warehouses. Customers wanted to bring data into their source of truth without having to maintain custom built pipelines or introduce security risks by contracting a third-party ETL/ELT provider. After seeing Stripe https://ift.tt/MbfsBFJ and customer.io https://ift.tt/GRINf1H recently invest in building out their own native data sharing products, we realized that many SaaS companies could better support their customers and even generate additional revenue by offering native data pipelines. Our goal with Pipebird is to make creating a reliable data pipeline as simple as pressing a button from a vendor's dashboard. With the current iteration of the product, data can be selected from a number of sources (ex: Postgres, MySQL, CockroachDB, etc.), customers can configure pipelines and optionally apply transformations (like type casting), and data can be periodically synced directly to customers’ warehouses (ex: Snowflake). We’re actively adding sources/destinations and would appreciate any feature requests. Here's a 2 min demo of the product https://ift.tt/aSjwgJ6 Pipebird is open source (MIT license) so that any developer can use it. Our aim is to not charge individual developers - we make money selling paid plans that include features like multiple projects, user permissions, additional security features, managed infra, support, etc. Give us a whirl: https://ift.tt/rG2XR6C . We’d love your feedback and will be here to answer any questions! https://ift.tt/rG2XR6C September 1, 2022 at 12:57PM

Show HN: Using GPT-3 to answer annoying interview application questions Hi folks. My wife has been looking for a job and sometimes in the application forms there are annoying questions like "Why do you want to work here?". At the same time I've been playing around with GPT-3 and have blown away by it's capabilities, so I decided to build a site that can answer these annoying questions for her. Github: https://ift.tt/UqKWdZj Here's an example of a generated answer: Using this opening for a Senior iOS Engineer at Monzo - https://ift.tt/4laW2KE The generated answer question on the application "What attracted you to Monzo?": "What attracted me to Monzo is that it is a bank that is trying to make a difference in the world by making it easier for people to manage their money. Monzo is also very customer focused and puts the customer first in everything they do." https://ift.tt/UCpubGY September 1, 2022 at 03:30AM
