Show HN: Bookable Schedule – Schedule meetings directly inside ONE email https://ift.tt/Muy2vrN

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 https://ift.tt/Hw3NOFs

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: Visualize SQL Queries https://ift.tt/xJXISzj

Show HN: Visualize SQL Queries My co-worker and I were debugging a SQL issue; having not seen SQL in two years, I embarrassed myself by confusing union vs. join. After this episode, I tried refreshing my SQL memory, but there are few websites that animate SQL for you. Most of them just have a series of images to help you visualize. There are a few tools that are quite good and robust (especially for large/complex use cases) but require installation and are too complex for my simple purpose. So, just created a small tool to help visualise SQL. Most of the animations are just my understanding of how SQL works. Would love to know what you think? Do you also visualise some of the queries like that in your head? Any feedback would be gold. Btw you can also edit queries and see different results (but its a bit limited). Have fun ;) https://animatesql.com March 29, 2022 at 04:30AM

Show HN: A Better Alternative to the AWS Console https://ift.tt/4Y2Wbnz

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!

You will also tast a bit of how variables work in Pipy. Takeaways Filter parameters are only evaluated once so they have a "static" value at runtime. To make them "dynamic", they need to be functions that output dynamic values. Global variables have isolated states between concurrent pipelines. One of the builtin global variables is __inbound, which contains address/port information about the current incoming connection.

Show HN: Throw – The new space for asking and answering questions anonymously https://ift.tt/d2cgO60

Show HN: Throw – The new space for asking and answering questions anonymously Hello HN community, For the past year we’ve been working on this disruptive new thing. It’s about people, community, communication and truth. Throw is the new space for asking and answering questions anonymously. We believe that in today’s world (both online and offline) content in communication exchanges is strongly influenced by the personas, profiles and façades people maintain/upkeep/safeguard socially, ideologically and on relationships. From the way people post on Instagram the life they want others to believe they have, or the way people behave on thanksgiving with family, or at work, or with friends; on every social setting and interaction to some degree acting and behaving according to that setting and the people they interact with. These dynamics influence the content itself, as people don’t just respond to a question like computers do. What ends up happening is that the responder comes up with the answer by blending the possibly objective answer with feelings, setting, desires, commitments, ideologies, fears, insecurities, etc (social pressure or social agenda). Something is missing between social media and the traditional Q&A… Throw addresses this by creating a space free from this social agenda. Thus focusing strictly on the content exchanged and providing a safe, comfortable and unbiased space where people can ask and answer anything freely with no bias, fears or strings attached. Not only may Throw be used for personal and private questions and answers. But the power of crowdsourcing allows for a great variety of use cases like market research, validation of content and ideas, trivia, and much more. Serious matters and also just for fun… It’s a query marketplace which means that “throwers” (people who ask questions) pay a fee proportional to the answers they need and in turn “catchers” (who catch them and respond) get compensated. This way we guarantee every user gets as many responses as he/she needs. As for dealing with anonymity, we have built a sophisticated moderation protocol to neutralize and quickly ban people that contribute negatively as it is a priority people feel safe and comfortable in this community. We have worked very hard to create a delightful product and are currently very close to rolling out our app to the market. If this is something that may be of your interest or you’d like to be one of the first to test it out, you may keep an eye for our launch and other news by subscribing to our waitlist. https://ift.tt/FPjrVob Also, if you have questions there is additional information in the FAQs section on our web page that could be of help. If you still haven't looked at our explainer video I encourage you to see it as it's quite fun and describes pretty well what we are doing. https://youtu.be/3f9RcVVpkNA Finally, we really appreciate any feedback we can get (of any kind). So if there's anything you like, don't like, or any other thought about Throw, we'd love to hear about it! You may post a comment below or through the contact section on the web page. Be curious and dare to know! Thank you! https://ift.tt/CdT8N0b March 25, 2022 at 06:54PM

Show HN: We made an open-source personalization engine https://ift.tt/Sc2gohi

Show HN: We made an open-source personalization engine Hey, HN! You probably know that the ordering of products on Amazon, posts in FB, and search results in Google is personalized for each visitor, as it directly affects conversion, click rate and engagement. But not everyone can afford to hire an army of PhDs to squeeze every penny out of the ranking, and not everyone agrees on the current (im)balance between privacy and profits. So we built Metarank, an open-source and privacy-focused personalization engine. It can rerank in real-time any type of content, using only the data you allow, and optimize metrics you define. We made a lot of proprietary DIY services for personalization in e-commerce in our past careers and heard so many complaints from other companies also struggling to implement personalization. It’s often considered "too risky" to spend 6+ months on an in-house moonshot project to reinvent the wheel without an experienced team and no existing open-source tools. Like other people in the industry, we were tired of building everything from the bottom up each time we approached personalization - it should be easy not only for Amazon to do such magical ML tricks, but for everyone else. A small demo of the tool with personalized recommendations: https://ift.tt/5Tth8EZ A blog post on how this demo was made: https://ift.tt/aR0LPYU...

Show HN: Vault – Sports bet data aggregation app https://ift.tt/qTofeNY

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.

Show HN: Open-Source 3D Location-Based Wireless Mesh Network https://ift.tt/gJrRply

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: Auto-Generated C4 Architecture Diagrams in Go https://ift.tt/Se638G7

Show HN: Auto-Generated C4 Architecture Diagrams in Go Hey HackerNews! One of the most common problems in IT projects is the problem of out-of-date documentation or lack of documentation. Architecture diagrams are an essential part of it. C4 Model is trying to help with that by providing a tool that helps to standardize a way to create clear architecture diagrams on multiple levels. But having a standard practice to follow is not enough to have this documentation up-to-date. Because of that, Krzysztof from my team created a script that can make these diagrams directly from the code. Unfortunetly we can't share our company code. Fortunately, we have Wild Workouts DDD example that is a perfect use case to show the power of that tool: https://ift.tt/5DsQ0k2... . The linked article describes all the needed steps to create these diagrams. Feel free to play with it and try to add it to your project. If you want to know more about Wild Workouts DDD example, they are already 14 articles that describe the project in detail: https://ift.tt/oaFmlRQ... . https://ift.tt/iJcyaVN March 17, 2022 at 06:43PM

Show HN: PDF API – Generate, convert, and modify PDF documents https://ift.tt/EN3wAkF

Show HN: PDF API – Generate, convert, and modify PDF documents Hi HN, Arek here. We’re super excited to officially launch PSPDFKit API [1]. PSPDFKit API is a collection of HTTP APIs that enable you to convert, generate, and edit documents without running any service on your infrastructure. What differentiates our API from others is that you can chain together multiple “actions” as part of a single API request. For example, you can convert, OCR, watermark, edit, and flatten a document — all in one call. Available actions [2]: - PDF Generator - PDF Converter - Image Converter - OCR - Watermark - Merge - Split - Duplicate - Delete - Flatten Our documentation includes sample code for JavaScript [3], Python [4], Java [5], C# [6], PHP [7], and the command line. We also have a Postman collection [8]. Let us know what you think or if you have any questions.

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: Fast subdomain enumerator written in Rust https://ift.tt/IzqXVhm

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: Sci-Hub Scholar – Firefox Extension Update v1.2 https://ift.tt/O6ClEGt

Show HN: Sci-Hub Scholar – Firefox Extension Update v1.2 Sci-Hub Scholar is a browser extension that takes Google Scholar search results and tries to point them at Sci-Hub, where they can be read freely. The main selling point for this extension versus others is that it works right on the results page, rather than the article page at the pay-walled website. One night, I decided I was going to do some research, only to find every Google Scholar Result behind a paywall. Trying to find the link on Sci-Hub, I ran into a bunch of issues: * https://ift.tt/AgzUCTP is down * Annoying to copy/paste title to Sci-Hub * Didn't want to be presented with another set of search results from my search results. I've seen some other Sci-Hub extensions, most notably https://ift.tt/AbfxzlH . However, most of these require you to go to the article page, then click the extension's button to finally be redirected. I thought I could do better. I recently did an update pass to update with some features others have added and requested. New Features for v1.2.0: * Added support for all Google Subdomains. You can now use this extension on Google Scholar websites for any country! * DOI is now listed next to the article title for articles where the DOI was found * If the title's URL was updated to Sci-Hub, the Icon to the left will now point to the original article. * More accurate DOI lookups! Issues: * Currently, I can't validate that the article exists on Sci-Hub, due to the way Firefox handles website permissions for extensions. I do not want to request permissions for all domains, but since the Sci-Hub domain can change, this is difficult. * I'm afraid to port this to Chrome, because I don't want to lose my Google Account over something like this. * It's a hassle to support manifest v2 for Firefox and manifest v3 for chrome. Haven't found a good workflow setup for developing for both browser platforms at the same time, from one codebase. I welcome any feedback or recommendations on the issues. I also have planned features, and am open to contributions! The extension is all open source and can be found at: https://ift.tt/XjNz0Jb I hope this helps some people get access to the information they need! https://ift.tt/l7XGEqN March 13, 2022 at 12:19AM

Show HN: Prepform – AI and spaced-repetition to optimize learning https://ift.tt/HD59nyP

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 https://ift.tt/8dkVpIs

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 https://ift.tt/i3WzR18

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

This is something that I would have liked to have had when I was working at a big company. Some caveats: 1.) Only iOS is currently supported but Android-support will be coming soon. 2.) You need a developer-signed IPA file (see the guide on creating an IPA file here: https://ift.tt/CikWwr4). I would appreciate your thoughts on: 1.) your barriers to trying it 2.) your impressions of the map 3.) whether you're interested in applying this within your team 4.) anything else. Don't have access to an IPA file? Email me at illahi@prodscape.net and I will send you one to try. Thanks! March 8, 2022 at 01:47AM

Show HN: I made a privacy-first minimalist Backblaze https://ift.tt/Vm7IXKp

Show HN: I made a privacy-first minimalist Backblaze Creator here. I was looking for something as simple as Backblaze Personal [1] but privacy focused and open source. This is my attempt to build that. Uses PyQt6 [2] for the GUI and Pyinstaller [3] for creating the platform specific binaries. The backup engine under the hood is Restic [4]. The server code is written in Laravel [5]. All the code is on GitHub [6]. I actually really like Backblaze (even use B2 for this offering behind the scenes) so this isn't meant to throw shade their way. Just wanted a private open source alternative. Something like Bitwarden but for backups.

Show HN: CL and FB reselling app with auto renew and auto price reduction https://ift.tt/RLUQ4gx

Show HN: CL and FB reselling app with auto renew and auto price reduction I recently moved apartments and had a lot of stuff I wanted to get rid of. I found the reselling process to be cumbersome – I needed to post the same info twice, to both Facebook and Craigslist. I had to renew the items so they don't expire. I also had to reduce the item prices if they didn't sell. So I decided to do what any right minded overzealous, "pragmatic" software engineer does – instead of spending 10 minutes every few days reducing the prices and renewing the items, why not spend 3 weeks to build out a fully decked out Electron app that does all of the above automatically for you? Why not indeed... In the end, it's been a fun ride and I learned a lot. And actually! now it's coming in handy as I'm finally starting to sell the backlog of items that I've accumulated. Once I built it, I figured I'd offer it on gumroad, make a buck, why not... btw, the link is for a discounted version ($1 instead of $10) so that you lovely HN lot can try it out. Curious if you all have thoughts / feedback! Hopefully it will help you out on your next move too! https://ift.tt/RQyOa6Y.. March 6, 2022 at 12:17AM

Show HN: RateYourRecruiter.dev https://ift.tt/qdjoAul

Show HN: RateYourRecruiter.dev Tech recruiting and interviewing sucks. So I created https://ift.tt/74Pot0c to hold recruiters to account. The elevator pitch reads: Interviewing for a role in a highly sought after tech company is broken. Recruiters have incentive to get as many people in for interviews, with little to none (or incorrect) information. Questions often have little to do with on-the-job responsibilities, and are rarely communicated to recruiting and back to the candidate. By having a more transparent process is not only more equitable, but will lead to greater success for candidates and recruiters. RateYourRecruiter.dev aims at demystifying the recruiting and tech interview process. March 4, 2022 at 10:04AM

Show HN: WAPM – WebAssembly Package Manager https://ift.tt/N4LsAyU

Show HN: WAPM – WebAssembly Package Manager Hi HN! I’m Syrus, from the Wasmer team. We just released the new version of WAPM that is an order of magnitude better than the previous one (that we also announced here in HN two years ago! [0]), enabling an incredible experience for using and publishing WebAssembly packages. The tech stack that we are using includes: * Python and Django (for the backend) with Graphene (for the open GraphQL API [1]) and Django Channels with websockets over GraphQL [2] for subscriptions * Next.js [3] with React-Relay [4] and Tailwind.css [5] for the frontend * WebAssembly and Wasmer [6] (for the online shell) Vercel for serving the frontend and GCP for serving the backend. Please let me know if you have any questions, I’d be very happy to answer them! https://wapm.io/ March 3, 2022 at 12:52AM

Show HN: I made a WebGL-based app that traces images using circles https://ift.tt/joJLwN7

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. FYI: this app is offline-only; your images never leave your browser [0] https://www.youtube.com/watch?v=r6sGWTCMz2k [1] https://www.youtube.com/watch?v=-qgreAUpPwM [2] https://ift.tt/Pro6wkp [3] https://ift.tt/qeYthsw https://ift.tt/ugedaB4 March 2, 2022 at 11:26PM

Show HN: I made a web game called Almost Pong Hi HN! I made many small web games in the past with Unity or Phaser. But this time I wanted to make something completely on my own. So I coded a basic game framework in plain JavaScript, and used it to make Almost Pong. This was a really fun project that taught me a lot about JavaScript, and I plan to make more minimalist games with this framework. Interesting fact: Almost Pong doesn't load any assets, all sprites and sounds are generated with code. Happy to answer questions, and please let me know if you have any feedback on the game. Thanks! https://ift.tt/5RF109n March 1, 2022 at 11:39PM
