Show HN: Colorfle – A daily color mixing game inspired by Wordle Hi HN, I was inspired by Wordle to make Colorfle, a different take on the genre where the goal is to mix colors together to match the target color within six tries. There were some interesting problems to tackle in making this game, one of them being the difference between mixing digital colors and real-life behavior (in RGB, blue + yellow = grey!). I hope you enjoy it -- any feedback would be much appreciated! https://colorfle.com/ April 29, 2022 at 08:20PM

Show HN: WeakVim, My attempt at a modular, transparent starter kit for Neovim Hi all, I _love_ Neovim. However, I think many parts of it could be easier to configure or understand, especially when it comes to LSPs. There's a ton of plugins that fill the gap, but some of them are sparse in documentation. There's also distributions like LunarVim that attempt to add a Doom Emacs-like layer above. My approach is a bit different, simply giving an opinionated, modular, and documented configuration that an interested user can easily modify to their needs. It makes use of the most helpful plugins I've encountered to create the best experience I could muster while retaining an air of simplicity. I hope this is helpful to someone out there! https://ift.tt/ykR8OzY April 29, 2022 at 05:33AM
Show HN: Lists.sh – A Microblog for Lists Greetings, creator here! I've been working on a new blogging platform specifically for lists on and off for a few months now and I'm excited to officially announce its launch. After seeing https://charm.sh a few months ago, I've been enamored by the idea of SSH apps. I decided that a blogging platform focused on developers could be the perfect use case for an SSH app. Also, I love writing lists. I think restricting writing to a set of lists can really help improve clarity in thought. The goal of this blogging platform is to make it simple to use the tools you love to write and publish lists. There is no installation, signup is as easy as SSH'ing into our CMS, and publishing content is as easy as copying files to our server. Check it out and let me know what you think! source: https://ift.tt/gdVMGUv https://lists.sh April 25, 2022 at 07:14PM
Show HN: Linen – Make your Slack community Google-searchable Hi HN! Kam here. I’m the founder of Linen.dev https://linen.dev , a website that makes your public Slack community Google searchable. Linen will sync your Slack threads and make it SEO friendly so your community can find Slack content that was previously hidden. Previously I worked on a popular open source project which had a sizable Slack community. Slack was great for engaging with community members and with early sales. However as community scales Slack becomes this black hole where context becomes lost. Most public communities can’t afford to pay for several hundred/thousand members so they are limited to 10,000 free messages. You run into the problem of people asking repeat questions and not searching in Slack. It also doesn’t help that the Slack UX encourages posting and not searching. We experimented with Github discussions and Discourse but didn’t want another channel to maintain and split the community on. With Linen I wanted to build a tool that is very low maintenance without changing my current workflow. By making it search engine friendly and putting it on a website the community members can find answers to repeat questions before ever getting into your Slack channel. Linen is the first result that comes up on Google if you search for “seeing a weird issue with flyte” https://ift.tt/q3dNS8l... or “replace beast http with proxygen” https://ift.tt/9hdYeu6... . As a side effect of syncing conversation to a website you end up with a very long tail of unique and relevant content for your community. Linen is free to use and get setup but I offer a paid version (I am still figuring out the pricing model for it) where you can get the content redirected to your own subdomain where your domain gets all the SEO benefits. Linen is built with Nextjs, Node, Typescript, React, Prisma for the ORM and using AWS aurora for the Postgres db. I chose Nextjs for the server side rendering capabilities and wanted to share types between client side with Typescript. I’ve also enjoyed working with Prisma as the ORM since you don’t have to write a lot of boilerplate with other ORMs. I've also been pretty happy with Vercel and Nextjs especially with the server side rendering and client side caching it provides. Here are a few communities on Linen right now: https://ift.tt/i5UDWm8 https://ift.tt/5TNdAIH https://ift.tt/vMtImUT https://ift.tt/gp0lomw https://ift.tt/gFdNQAV https://ift.tt/UmWlTXw The product is very simple right now but I want to add features like related questions detection with semantic similarity, integrating with Github to notify the thread when it is finished, auto thread detection for conversations that aren’t in thread form. You can sign up for free today at https://www.linen.dev . I am doing manual onboarding at the moment to get better feedback and to manually walkthrough some of the less polished parts of the boarding flow. p.s. I’m actively working on supporting Discord on Linen so would love to hear from anyone that is interested April 26, 2022 at 09:10PM

Show HN: I'm making a dynamic language in Rust https://ift.tt/lfAdGk3 An implementation of a dynamic programming language in Rust. Includes: Parser/Compiler, REPL, Virtual Machine, Bytecode Disassembler This started out as a learning project to teach myself Rust. It has grown into a decently substantial piece of software and I've learned quite a bit in the process! Some neat things: + A garbage collector that can store dynamically sized types without any double-indirection (i.e. I have my own Box implementation with manual alloc/dealloc) + The smart pointer used to reference GCed data is a thin pointer. The ptr metadata needed for DSTs is stored in the GC allocation itself, so that the GC smart pointer is just a single usize wide. This allows me to keep the core value enum Variant down to 16 bytes (8 bytes for data, the enum discriminant, and some padding). + The GC also supports weak references! + Statically dispatched type object model using a newtype wrapper and Rust's declarative macros. Ok, what that means is that I have a MetaObject trait that I can use to easily add new data types and define the behavior for specific types. Similar idea to Python's PyTypeObject though very different in implementation. However, I don't resort to dynamic dispatch or trait objects despite working with dynamically type data. Instead, I have a newtype wrapper over the core value enum Variant that statically dispatches to each of the enum branches! And then a few macros that minimize the boilerplate required if I want to add a new branch to Variant or a new method to MetaObject (just a single line in each case). + Different string representations! This was inspired by the flexstr crate. Strings that are short enough to fit inside a Variant are "inlined" directly in the value. Longer strings are either GCed or interned in a thread-local string table. All identifiers are interned. + An efficient implementation of closures inspired by Lua's upvalues. The language is still pretty WIP. I'm planning to add an import system, a small standard library, and a few other things (Yes, the name might not be the best, being also used by a well-known ReST docs generator, I'll take suggestions. I do like the name though, both as a reference to the mythological creature and the cat :D) April 25, 2022 at 05:16AM
Show HN: A better Reddit search engine to find Menswear recommendations Hey HN Community! We built this simple community search tool that basically allows people to search through thousands of past Reddit threads and tens of thousands of recommendations using tags. It mostly covers a few bigger subreddits like r/BIFL, r/MFA, r/AskMen, r/SkincareAddiction but along the way, I expanded it to include other smaller subreddits too. In addition to filtering by category, power users can also search by -Body Fit (big thigh, long torso) -Occupation (work in retail, teacher, doctor) -Age (18-24, 25-35), Size (height, weight) -Brand comparison (similar to: X) -Use (suitable for wedding, everyday wear) -Location (available in UK, use in Northeast US) -Mood/Style (minimalist, vintage, retro) Check it out.

Show HN: Two-way Jira sync in a collaborative spreadsheet and Gantt Hello HN, Our startup nearly died 2 years ago. We kept losing customers to spreadsheets. And it made us see a problem right under our nose: everyone just wanted flexibility & speed from a spreadsheet. But they have to stay in sync with {Jira / Salesforce / insert SaaS app}. When we followed this thread, we discovered how broken the integration experience was for flexible products like Airtable, Smartsheet, Monday, and Google Sheets. Their big problem is that they transform external data into their own format. This makes setup harder, since you have to get the mapping just right. And often you can’t sync back. We took a different path when building Visor. We essentially made a data lake & ETL tool with a front-end. Visor integrates with your Jira instance, reads its schema, helps you import the right data, and lets you work in a flexible spreadsheet* that syncs both ways. There’s also an interactive Gantt & Timeline view. *Spreadsheet is a generous term for now. Formulas are still on the roadmap. As are many true “spreadsheet” features. But we’re working towards it. Our roadmap is public, here: https://ift.tt/gd821mE And for VueJS devs, we eked out more performance from Vue 2 by modifying the core, documented here: https://ift.tt/4KdYESi...

Show HN: Heyhey – Building a Linktree-like app taught me more than college Hello Hacker News! HEYHEY is a service that will hopefully bridge the different parts of people's online lives. So far, I've spent about 2 months developing it, and as a college student, it honestly helped me learn more about computer science than any undergrad course we have. Also, after getting the inspiration from HN, I wanted to prove to myself that, in 2022, anyone could build a full-fledged web service alone. Thanks to its modern-yet-traditional infrastructure, HEYHEY is costing me about 0 dollars a month to run (so far!). I really wanted to keep the service simple but functional. So naturally, I tried to stay away from a JS-based front-end. Instead, HEYHEY uses simple HTML pages with modern CSS and forms to function (you can disable JS!). Last week, I silently turned on registers, and if you register today, you will have a 10% chance to get Pro for life — it enables custom usernames (heyhey.to/[username]) and rich themes. I am not trying to take over the "Linktree space", nor trying to build a unicorn startup. After making HEYHEY presentable, I just wanted others to have access to it as well. I hope to keep developing HEYHEY so that it can further integrate with other social platforms while staying lightweight and functional. Would love to hear your feedback!

Show HN: Employees.fyi – Easily compare U.S. workforce demographic data Hi HN! We built Employees.fyi to make it easy to compare U.S. workforce demographic data across companies and against industry reference data. In the U.S., the Equal Employment Opportunity Commission (EEOC) requires the collection and submission of demographic workforce data. We collected and organized the publicly available federal data from the EEOC as well as publicly available EEO-1 submissions from individual companies. By doing so, we hope to make it easy to compare U.S. workforce demographic data across companies and against industry reference data. The URL contains your current selection. Just copy the URL and share it!

Show HN: Tool for freelancers to calculate how much money to set aside After having been a regular employee for years, I worked as a freelancer for a while. Going into my freelancing life I had no real mental model for how much of the money I earned was truly mine to spend, and how much of it I needed to set aside for taxes, vacations, retirement, and in case I got sick. I modelled this in Excel as best I could and was quite surprised both by how complicated it was to get right, and how much money I actually needed to set aside! As my girlfriend also started freelancing last year, I decided to turn my Excel sheet into a little program she could use too, and in the spirit of sharing and helping others I would hereby like to make it available to you all too :) My biggest take-away so far has been that most people dramatically underestimate how much they need to set aside, and forget to plan adequately for getting sick and for retirement.

Show HN: A small Hypercard stack running as a PWA In my early programming years, I went from BASIC to HyperCard, then learned C when I couldn't make HyperCard do everything I wanted. Plenty of folks have pointed out how the lack of native support for color doomed HyperCard. But I think it was really over when the web got started and replaced everything in the "personal content" space from underneath, so I decided to see if the idea of HyperCard would work as a web app. There are some missing pieces -- it's not perfectly compatible.

Show HN: Razer x Lambda Tensorbook Hi all, long time lurker, first time poster. I want to share with you all something we've been working on for a while at Lambda: the Razer x Lambda Tensorbook: https://www.youtube.com/watch?v=wMh6Dhq7P_Q But before I tell you about it, I want to make this all about me, because I built this for me. See, while I'm genuinely interested in hearing from the community what you think as this is the culmination of a lot of effort from a lot of people across so many different fields (seriously, the number of folks across manufacturing, engineering, design, logistics, and marketing who have had to work together to launch this is nuts), I really just want to tie the larger motivations for Tensorbook as a product back to a personal narrative to explain why I'm so proud. So, flashback to 2018, and I'm a hardware engineer focusing on the compute system at Lyft's autonomous vehicle (AV) program, Level5 (L5). Here was a project that that would save lives, that would improve the human condition, that was all ready to go. I saw my role as coming in to product-ize, to take what was close to the finish line and get it over it. The disappointment was pretty brutal when I realized just how wrong I was. It's one thing to nod along when reading Knuth write "premature optimization is the root of all evil"; it's another to experience it firsthand. At Lyft L5 I thought I would be applying specialized inference accelerators (Habana, Groq, Graphcore, etc.) into the vehicle compute system. Instead, the only requirement that mattered org-wide was: "Don't do anything that slows down the perception team". Forget testing silicon with the potential to reduce power requirements by 10x, I was lucky to get a willing ear to hear my case for changing a flag in the TensorFlow runtime to perform inference at FP16 instead of FP32. Don't get me wrong, there were a multitude of other difficult technical challenges to solve outside of the deep learning ones that were gating, but I had underestimated just how not-ready the CNNs for object detection and classification were. Something I thought was a solved problem was very much not, and ultimately resulted in my team and others building a 5,000 watt monster of server (+ power distribution, + thermals, + chassis, etc etc) that took up an entire rear row of seating. I'm happy to talk about that experience in the comments because I have a lot of fond memories from my time there. Anyway, the takeaway I have from Lyft, and my first motivation here is that there is no such thing as over-provisioning or too much compute in a deep learning engineer's mind. Anything less than the most possible is a detriment to their workflow. I still truly believe AVs will save lives; so by extension, enabling deep learning engineers enables AVs enables improvement to the human condition. Transitive property, :thumbsup: So moving on, my following role in industry was characterized by working closely with the least technical people I have ever had the opportunity to work with in my life. And I mean opportunity genuinely, because doing so gave me so much perspective on the things that you and I here probably take for granted. (How do we know that Ctrl+Alt+T will open a terminal? Why does `touch` make a file? How do I quit vim?) So, the takeaway from that experience, and motivation #2 for me is that computers can be so unaccessible in surprising ways. I have a deep respect and appreciation for Linux, and I want others to see things the same way, so anything I can do to make easier the process of "self-serving" or "bootstrapping" to my level of understanding, is something worth doing to me. So, with those two personal motivations outlined, I present to you, for your consideration, the Razer x Lambda Tensorbook. A laptop with a no-compromise approach to speeds-and-feeds and shipping with OEM support for Ubuntu. sincerely, Vinay. Product Marketing @ Lambda April 13, 2022 at 12:12AM
Show HN: Dev Toolbox – A browser extension with simple offline dev tools Hello HN! I'd like to share a browser extension I made that provides quick offline access to various development tools. Current tool set: Calculate hashes; encode and decode HTML, URI, Base64; convert numbers between different bases; parse and manipulate various time formats; format and inspect IPv4/CIDR addresses; search all v13.1 emoji with quick copying in various formats. It runs entirely offline, making no external requests (even emoji PNG files are bundled), and only requires local storage permission to remember your last tab and input. This was inspired by an old extension called Hasher (no longer on the Chrome Store) that provided a simple interface to similar utilities. This was an opportunity to get back into making extensions, practice with Vue a bit, and expand upon the original idea. It's available for Chrome, Edge (via Chrome Store), and Firefox; links and screenshots are on GitHub, where you can also report any problems. Feedback and suggestions are very welcome.

Show HN: Relevanto (beta) – I curate the relevant web Hi! This is Alex Dragusin and lately I've been working on Relevanto where I look for and save the best of the web. I literally search through search engines for the best of everything (yes, lots of site:reddit.com in there and so on), check it out if it's legit (I search for reputational data like reviews etc) save it, categorize it and list it on Relevanto. I have a knack for curation and organization so I am putting my skills to, hopefully good use. This, at this point is intended for a global audience, stuff that make sense for most people. I got fed up with Google and other search engines results being filled with too many results that are not really useful and I hope Relevanto will eventually be a gateway for most of the stuffs I do on the web, leaving the search engines for more specific stuffs - to use them as an option rather than primary way. Love speed and privacy. I am big on privacy thus no tracking and the usual nonsense. The site is static and managed by a backend I created through which I manage the sites in the database. The static exporter is written in PHP. Nothing too fancy. I am constantly adding, adjusting and since it's beta, many more categories are coming up. In the works: *apart from the highlighter, a similar function that will filter all the sites by [keyword], that is, show only what contain [keyword], hide everything else. *dedicated pages, for example Music, on this page there will be all about music from links to websites for consumption to tools of creation to news and so on. Monetization: Will monetize in 2 ways, one by having a Marketplace page (the only place for ads, no ads on other parts of the site as long as I am at the helm), where one can advertise their service/product/company for a consistent fee (aka high barrier of entry) while abiding by strict guidelines (Money is good but not at the expense of my visitors!) and second by patronages taken through Patreon or other provider. That's it, the goal is not endless growth at the expense of the users but to provide value, real value! This is the future of the web, the relevant web! Thank you and hope to have you along for the ride. https://ift.tt/9myfhdN April 9, 2022 at 12:09AM

Show HN: Bookable Schedule – Schedule meetings directly inside ONE email Hi Hacker News! We released a new meeting scheduling product today! You can use Bookable Schedule in Boomerang for Gmail or our iOS app to create a set of availabilities and share it as many times as you’d like inside your email. Recipients receive an image of your live availabilities and through the use of image maps, they can see and pick the right appointment slots directly inside whichever email client they’re using. If the recipient also has Boomerang, they can overlay their calendar on top of the schedule (still inside the email) to see which times work best for them! It works great for things like office hours, client appointments, sales calls, and more. It also doesn't shift the work of scheduling meetings to the person you're inviting, so it's better etiquette[1] and easier for recipients as well as the scheduler. Please feel free to take a look and play with it, we’d love to hear your thoughts!

Show HN: Code reviews intimidated me, so I built a course on how to master them I’m excited to share Master the Code Review: forge a better process, give better reviews, write better code. It’s a video course with 4+ hours of content [1]. I’ve linked a 21-minute sample below [2]. 6 years ago, I began my software engineering career at Amazon Web Services. I struggled with Pull Requests. My authored PRs received many comments, sometimes 50+. They went through many revisions, sometimes 7+. I often shipped late. My reviews of other PRs were surface level and counterproductive. Long story short: I improved. Through trial, error and experience I learned how to be effective in all 3 dimensions of code reviews: process, reviewer, and author. I came to realize that there isn’t much information out there, giving developers actionable guidance to succeed in a code review environment. Doing so takes specific soft skills, social skills, and technical skills. Very few people talk about them. Late 2020, I started writing about code reviews on my Medium, Twitter [3] and LinkedIn. I grew from 0 to almost 17K followers across platforms. The internet held me accountable for ambiguities and inaccuracies of my public writing. I learned a lot, and leveraged both positive and negative feedback to refine my ideas. My writing experience gave me the confidence to build the course. I created it for my younger self, and I hope developers everywhere find it useful. I launched it a month ago. So far there have been more than 650 students. I’ve received positive feedback from senior managers and principal engineers across big tech. Happy to answer questions!

Show HN: A Better Alternative to the AWS Console Hey HN: Kaveh here, the founder of https://www.usage.ai/ We launched a new free tool to help engineers understand their AWS spend. Why? Because the way it's done now is a pain. DevOps and Software Engineers end up end up becoming cloud accountants or end up forking over a big % of their AWS bill for a tool to understand costs rather than focusing on business problems. Previous to founding Usage, I worked on high-performance computing research at JP Morgan Chase and as a software engineer at a number of smaller startups. Here's how this new tool works: It's fully self-serve and free to use. You connect a limited-access IAM role (read-only + ability to manage RIs and SPs). You'll see cost reduction recommendations on the Recommendations tab, your active and utilization status on the Plans tab, and the ability to splice-and-dice your data on the Instance Search page via Filters. We make money off of a 20% Savings Fee. If you choose not to let Usage optimize your spend, you'll never need to spend money on Usage. Happy to chat directly kaveh@usage.ai Have you experienced any issues with managing your company or organization's AWS expenses? We'd love to hear your feedback and ideas!

Show HN: Automation the KISS way. No YAML involved Hello HN, I like Ansible as a tool for automation to perform tasks on multiple remote hosts. But like many of you, I'm sick of the custom YAML DSL that many of this kind of tools provide. How many times have we said "just give me a true scripting language!" ? That's why I started this project `tricorder` (as in Star Trek's tricorder, a simple device to do pretty much anything required by the plot). For now, it's only a tool to execute a command on multiple hosts (like ansible, but without the YAML) and returning the outputs as JSON so you can query it with other tools like `jq` in your bash scripts. But with time, I intend to add other tools to provide the following features: - mimic the "gather facts" feature from ansible - upload/download files to/from remote hosts - Rust API to include in your projects - bindings to other languages like Python/TypeScript/Go I'd be happy to have some feedback on the source code (as Rust is not my main language) or on what features you'd like to see implemented. Thank you :) Link to the Github repository: https://ift.tt/7AgSouQ March 26, 2022 at 01:46AM
Show HN: Vault – Sports bet data aggregation app Hey HN, this is Caleb and Zach, we co-founded Vault after realizing how behind the times consumer-facing tech was in the sports betting industry. After creating various products and prototypes for sports bettors for most of 2020 (many with little/no success), in early 2021 we realized a key problem that sports bettors faced... Most of them were tracking their bets, ROI, and net profit using Excel tables or other forms of manual entry. Gaining inspiration from fintech apps such as Intuit Mint and CoPilot, both of which link with your financial accounts and aggregate your data, we created Vault. An app that links with a bettor's sportsbooks (i.e. DraftKings, BetMGM, Caesars) and aggregates that data. Would love to hear your thoughts, and feel free to reach out to Zach and I at info@vaultsportshq.com https://ift.tt/v7h4yi2 March 23, 2022 at 03:52AM

Show HN: Open-Source 3D Location-Based Wireless Mesh Network I've decided to open source the project I've been working on called Hyperspace. Hyperspace is a suite of software implementing a wireless mesh network for IoT devices. My main requirements are listed on my repo but I'll copy them here. 1. The mesh shall enable nodes to route packets amongst themselves. 2. The mesh shall allow nodes with limited power to participate in routing packets. 3. The mesh shall be IPv6 based. 4. The mesh shall be local. I.E. not require connection to a remote server. 5. The mesh should provide 3D location to nodes in the network. Nodes use the Decawave DW1000 UWB radio to transmit and receive data, and to measure distances to other nodes. Location can be determined with enough distance measurements (see the documentation for more details). The implementation is pretty primitive at the moment. The border router server and the iOS app are super basic and have very little in terms of actual functionality, but the core ideas are there. I'm not happy with the state of smart home devices. I don't like it when a manufacturer shuts down a key server and bricks a bunch of devices. I don't like it when devices don't interoperate. Therefore, I've decided to open source this project in the hopes that it gains traction and that we can work on creating better IoT devices together. https://ift.tt/RZ7n8yq March 21, 2022 at 05:15AM
Show HN: I built a platform for projects to find maintainers A few days ago, someone I follow asked the community for help maintaining his side-project, 512kb.club. This got me thinking. There are loads of maintainers out there feeling burnt out, but they can't abandon their project since people are depending on the project to be maintained. In an effort to combat this, I built a website that lists projects looking for new maintainers. It's still quite empty and has some rough edges. Any feedback is very welcome! https://ift.tt/WJTEGrY March 21, 2022 at 02:02AM
Show HN: A photo sharing app that isn't trying to be a TikTok clone We launched Pidgeon a few weeks ago, and since then we've had a chance to fix a lot of bugs and upgrade the usability a significant amount. The app is made just for photo sharing. No videos, no NFTs, just pictures, comments, and chats. Each post is ranked like on reddit - a combination of the user upvote/downvotes and the amount of time passed since the post's creation. We're also trying to stay away from ads, and instead adopt a freemium model. The main reason for this is because people are a lot more concerned with privacy these days, and if we aren't serving ads, then the user knows that we don't have an incentive to steal their data. There's already a small community of about 1500 on the app, with a lot of them being professional photographers. So the photos going up look really nice (at least in my opinion). But we don't just want to be a community of people who consider themselves photographers - that's a mistake that other platforms like Flickr and VSCO make. To become widespread, you need to make your platform simple to use for the casual person; only catering to professionals will necessarily keep your community smaller than it otherwise would be. Users have been asking for a desktop client, and while we don't have one yet, we do plan to add it - and it won't take us as long as IG to do it, and neither will it be an afterthought where the UX is intentionally made poor so that you're pushed to use the app instead. But we want to polish the mobile app first before we get there, and there's still a lot of work to do since it's super early days. If you want to try it out, here's the link: https://ift.tt/pbj6LV1 https://ift.tt/i0lpuHa And please do provide any feedback you have on the app! It really does help us make it better.

I’ve worked on other projects in robotics and object tracking (perception for self driving cars), but this has a whole different set of challenges. Nerf rival rounds travel at over 100 feet per second and shooting them out of the air requires aiming systems that are precise to less than half the width of a human hair and timing precision of 600 times faster than the blink of an eye.

Show HN: Fast subdomain enumerator written in Rust Hello! I'm learning Rust and also information security, so what better way to learn than to put a tool together practicing both skills? I've tried to use a couple of different tools for subdomain enumeration (part of the Discovery-party when it comes to penetration testing), but none of them were very fast, even if the DNS resolver I pointed them towards is, so I wrote my own tool that leverages concurrency to check a lot of subdomains, fast! It's written in Rust, main parts being using Tokio and async_channels, and I think it works good enough for a first release. I wanted to get recursive subdomain enumeration to work too, but couldn't figure out how to send into the same channels I'm reading from and knowing when to close the actual channels. Will work on that next! If you want to check out the project, it's located here: https://ift.tt/4cq0ZAf I'd love your feedback on the code, idea or anything in general! Usually people here have very good feedback, so I'm excited to hear what you think. Thank you! https://ift.tt/4cq0ZAf March 15, 2022 at 11:21PM
Show HN: I made Devzat – It's like discord but in the terminal, over SSH Run `ssh devzat.hackclub.com` to try it out! The repo is here: https://ift.tt/OJgTkqe (golang). It has markdown and emoji support, DMs, channels, and it can show images too. You can send code, and it gets syntax highlighted (you can change the theme). You can ping people like so: @user and it sends them a \a, which should play an audible sound if the terminal allows it. There's inbuilt games and rainbow names and a lot of other small things I don't remember right now. You might find the auth system interesting: it's based on a hash of ssh pubkey (bans use that and a hash of IP, so it isn't so easy to get around a ban) Also an interesting issue: bots that go around trying to brute force ssh into random IPs with common usernames. My current solution is banning if rapid successive joins are detected. March 15, 2022 at 11:32PM
Show HN: We’re the founders of Substack, we just launched an iOS app. AMA Hi! This is Chris Best, Hamish McKenzie, and Jairaj Sethi, the founders of Substack, with Sachin Monga, the head of product. Yesterday, we launched an iOS app for Substack, so you can read all your Substack subscriptions in one place, with no distractions. Readers have been tweeting at us for years now to ask when we’d have an app. We’ve long wanted one too, and we suddenly got the manpower to be able to build a good one when we acquired Sachin’s company Cocoon (W19) last year. Soon after starting Substack, we found it easiest to explain what we do as “We make it simple to start a paid newsletter.” Even then, a Substack was more than just an email newsletter: it was also a blog, and it could host embedded video and audio, and people could leave comments and participate in discussion threads. But the term “newsletter” was useful shorthand because everyone kind of got what that meant. All along, though, we’ve been quietly building the tools for what we call “personal media empires,” encompassing different media formats (natively) and community discussion (which we intend to make better and better). By a similar token, right from the start we’ve been intending for the company to do more than just provide subscription publishing tools. We’re excited by the vision of Substack becoming a network, where writers and readers benefit from being part of a larger ecosystem. For writers, it means they can be discovered by readers who might not otherwise have found them. For readers, it means being able to connect directly with writers and other readers and to explore a universe of great work. The app is a key part of the network vision. Nothing changes in terms of writers and readers being in control. The writers still own their mailing lists, content, and IP and can take it all with them anytime they want. Anyone who signs up to a Substack through the app still goes on to that mailing list. And readers still get to choose what appears in their “inbox,” with the power to subscribe and unsubscribe from whatever they want (you can also add any RSS feed into the app via reader.substack.com). But now we’ll have more and better ways to surface recommendations from writers and readers, to show people’s profiles, and to deliver notifications inside and outside of the app. This is just a start for the Substack app. We want to keep improving it, so please give us feedback and ask us the hard questions. What do you think we’re doing wrong? What could be better? What could be great? What might we not have thought of? We’re here for the next couple hours. Ask us anything. https://ift.tt/Q8brjoU March 11, 2022 at 03:21AM
Show HN: Prepform – AI and spaced-repetition to optimize learning Hi, I'm Eric and I'm the founder and lead developer of Prepform. A high-quality education helped me pursue my interests and achieve my goals. I started Prepform so students of all backgrounds have access to the same kind of education. I grew up in Southern California, surrounded by dozens of SAT prep programs, and I swear I must have gone to all of them. Different programs followed different styles and techniques, but the strategy they shared was to create a study plan and review mistakes. A study plan is taking a diagnostic test, setting a target score, creating a study schedule, identifying mistakes, and finally reviewing those mistakes. I wanted to take this structure and optimize it with machine learning, while accounting for elements of human learning and memory. I'm a big fan of SuperMemo, a memorization technique developed by Piotr Wozniak, where you review material just as you're about to forget it. Cognitive psychology tells us human forgetting follows a pattern, but Piotr quantified this behavior to identify the precise moment forgetting happens. The goal was to build on his research with AI and tailor it to not only test prep but to the individual student, and make it the engine of the study plan. The result is Blended Prep, which guides students to internalize knowledge rather than memorize material, and gives them the best chance to ace their next exam. I'm so excited to share this with the HN community, and would love to know what you think. You can try it out at https://prepform.com . Thanks for reading. https://prepform.com March 11, 2022 at 01:57AM
Show HN: I wrote a good React book / website Pre-covid, I was traveling full time to teach ReactJS to corporate clients. My students (mostly developers at banks and insurance companies) would ask me 'What's a good React book?' and I would struggle to recommend something, knowing that all the books sucked or were really out of date. When all my face-to-face training work dried up and I really didn't want to do online training, I magically got a contract to write a book. I started by reading all of the best-selling books on React, and, yeah, they were all really out of date, incomplete, or just wrong. As I started writing what I hoped would be a really good React book, I also wanted the website to be something useful and a notch above a typical book website. So, I tried to have working examples of the code listings on the site and to organize them in a way that would make them useful for when I started teaching again, or for anyone who doesn't want to buy a book and just wants to see how things are done. The book just came out today! The website isn't perfect or done, but here it is: https://ift.tt/QeYSvkf . How'd I do? March 10, 2022 at 02:40AM

Show HN: Kaado.io – Unifying Personal Productivity Hi HN, a while ago I discovered a problem with problem with personal productivity tools: Every time you find a tool that works well in one regard (say, habit tracking), you neglect your previously working systems (say, your to do list system). So I set about to build a system which unifies all the different aspects of personal productivity. Everything is represented in cards (like flash cards) which are defined in Markdown. The following types of cards exist: * Learning : Classic front/back prompts to memorize things. Think "What is the capital of Argentina?" on the front and "Buenos Aires" on the back. Works with a spaced repetition algorithm so time between prompts is optimized. * Habits : Recurring actions you want to do - you can set the frequency individually. For example "Stand up and walk around your room" every two hours. * Checks : Recurring prompts, similar to habits, but always questions referring to the past. For example a daily "Did you drink enough today?" prompt * To do : One time actions that are deleted upon completion. * Reading List : Used for books, articles, talks etc. There are always a limited number of reading list items active, which will prompt you to read a page a day until you are done with the given book. * Other : Everything else - interesting websites, quotes, art or even memes that you will occasionally see. The idea is that there is a single queue for all types of cards, only ever showing you one item that's due next - whether habit, learning prompt or a random note. This prevents choice fatigue, the dread of lengthy to-do lists and the boredom of endless dry learning prompts. I've been using the app successfully for myself for quite some time now but would love external feedback. You can check it out at https://kaado.io. It's currently completely free (and in fairly early stage development). Simple email signup is needed but you won't get any unprompted mails. Apart from that I would love your takes and ideas regarding personal productivity and what works for you. March 8, 2022 at 08:32PM

Show HN: Mailwitness – Digital Signatures over Email Hi HN, I'm Marek Dopiera and I wanted to share the digital signature solution which I made with my software house. Your feedback would be much appreciated. We've just launched it - it's a service for signing documents over e-mail - https://mailwitness.com . It still has some rough edges, but hopefully it is useful already. To sign a PDF with somebody, you e-mail them the PDF and put sign@mailwitness.com in CC. If they agree, they need to forward it to sign@mailwitness.com. When they do, you all get your document signed. You can generate PDFs from e-mail, too for convenience. We made this to raise the safety bar of agreements made via e-mail. Via anecdotal evidence, we know that if people do not use services like DocuSign or HelloSign, they consider an e-mail conversation as proof or they print, sign and scan documents. I think we're offering more safety and convenience, because we're preventing the documents from alteration, forging fakes and backdating (by using OpenTimestamp, which essentially constructs a Merkle tree and puts its root into a Bitcoin transaction). I'm hoping that our service becomes useful also because it doesn't require any sign-up (just one confirmation e-mail for Ts&Cs), it's free (in the basic model) and doesn't require the extra cognitive load on learning a web app or a mobile app. You may argue, that one can create a fake e-mail account and use that. That's a valid point, but the reality proves that verification via e-mail is enough for lots of people (vide the agreements over e-mail or DocuSign or HelloSign). In the future we may create paid options, which would include extra identity verification. Even without that extra option, things are not as bad, though: if you use your work e-mail, it's usually your employer who verified your identity. Another question you might have is spoofing. If your e-mail has a valid DKIM signature (which is the case for most major e-mail providers), we'll accept your message. If it doesn't we'll send you a message to verify that you can also receive e-mail. For data safety, we have designed the service such that we discard the documents as soon as we process an e-mail (usually a low number of seconds). Finally, there is legal safety. We operate under the EU law, which qualifies us as a "Trust service provider" and puts requirements on our service. What we do, qualifies as an "Advanced Digital Signature" and according to the EU law, cannot be denied legal effect based on the grounds that it is digital. Monetization path is unclear yet - I want to see if this catches on and if yes, how people are going to use it. Some options include extra services like using your own certificate rather than ours or identity verification. I would really love to hear your feedback - especially for what reasons you would not use it. Thank you https://mailwitness.com March 4, 2022 at 11:26PM
Show HN: I made a WebGL-based app that traces images using circles I was fascinated by this [0] and this video [1]. After many struggles, I finally built this app that traces images using circles similar to what these videos had shown. The most challenging part (to me) is to find a way to convert images to vector lines. I had tried Potrace, but its output is not suitable for my use case: too many small elements share the same border. Potrace's goal is to represent the original image faithfully using vector lines. But I want to trace the image edges. After searching and trying some Potrace alternatives in vain, I finally found my keyword. Surprisingly (to me), it lies at the end of the wiki page of the very topic [2]. Then I found a paper [3] that has nice pseudocode and a C implementation. I rewrote the pseudocode in Rust because I wanted to experiment with rustwasm. Honestly, I didn't care much about the math behind it. From then, I could continue to finish the app and show it to the world. This app is also my chance to learn about rustwasm and WebGL.

Show HN: A more social, Amazon-free alternative to Goodreads Hey HN, I know reading books isn’t everyone’s thing, but it’s certainly been mine for as long as I can remember. Unfortunately, I felt like the online book space was missing a platform that does the book community justice. Goodreads is the go-to "social platform", but if you've been on Goodreads before, you'll probably agree that it's not all that social, and overall not all that exciting. So I set out to build what I personally was looking for (but could never find). The goal: to give the book community a more social and streamlined alternative to Goodreads or StoryGraph. We also felt like it was important for Booqsi to be independent of Amazon; we care about supporting local bookstores, so every book in Booqsi links you to Bookshop.org to purchase that book (not Amazon). Here are some of my favorite features launched as part of beta: - A book-focused social feed (finally!) - Beautifully-rendered custom bookshelves to show off to your friends - Streamlined book recommendations to friends - Easily track reading goals and books you've read And many more...

Show HN: A Network of Knowledge Feeds Hi Everyone, I wanted to talk to this community about a particular story from my experience to see how the community feels. I have noticed that I have a lot of educated friends from top universities in my country who are having problems finding work due to a lack of experience, which has brought me to a conclusion that diplomas and CVs are not really good at conveying the knowledge someone has. A friend of mine who is already working on his own company told me that he had trouble finding people to work for him, so I thought about an idea that I am currently incorporating into my app. Perhaps we could make it much easier for you to show your knowledge to companies, as easy as show and tell. A network of live knowledge feeds that constantly keep updating over time showing how someone has evolved. If you know something, put it on full display for everyone to see, show something you have made and explain how you made something so that everyone can understand. If you are good at something, you probably won’t have a hard time explaining it to others, and other people could perhaps learn something by simply following your feed. Educational Institutions have curriculums that aren’t really adaptable, but if we rely on people expressing their unique knowledge to the world, we can create countless combinations of curriculums that will be much more adaptable for the problems we have to face today. I will be trying this approach with some friends over the coming days. My friends are looking for graphic designers, software engineers and music producers. They have established brands and are going to ask people who want to work with them to submit something they made and explain how they did it for everyone to see. You are welcome to join us at EWS ( https://ift.tt/xW7Gme2 ). If this sounds like a good idea, maybe we can kick off a challenge that you can share with your friends to #ShowWhatYouKnow. If you have a company, are looking for employees, maybe you can ask people to show something they made and explain how they made it to see whether someone has the knowledge required to work for you. https://ift.tt/xW7Gme2 February 25, 2022 at 02:16AM
