Show HN: A Full-Stack Web Framework for Go Hey HN! I want to share my side project with you. It's called Bud and it's a full-stack web framework for Go. I created a short video to show you how to create a minimal Hacker News clone with Bud: https://www.youtube.com/watch?v=LoypcRqn-xA . The framework is free, open source and MIT Licensed. You can find it on Github: https://ift.tt/m8a1ILk . I started working on Bud 2 years ago after watching the introductory Laracast videos about the Laravel web framework. I was just blown away by how productive you can be in Laravel. However, like many of you, I've been so spoiled by Go. I didn't want to go back to writing PHP, so I decided to try creating Laravel for the Go ecosystem. At this point, I just had the following goal: • Be as productive as Laravel in a typed language like Go. I got the first version working in 6 months and tried building a blog from it... It fell flat. You needed to scaffold all these files just to get started. If you're coming from Rails or Laravel you may shrug, this is pretty normal. Unfortunately, I've also been spoiled by the renaissance in frontend frameworks like Next.js. What I love about Next is that it starts out barebones and every file you add incrementally enhances your web application. This keeps the initial complexity under control. With these newly discovered constraints, I started working on the next iteration. Bud should: • Generate files only as you need them. Keep these generated files away from your application code and give developers the choice to keep them out of source control. • Feel like using a modern JS framework. This means it should work with modern frontend frameworks like Svelte and React, support live reload and have server-side rendering for better performance and SEO. With these new goals, the Bud you see today started to take shape. But along the way, I discovered a few more project goals: • The framework should be extensible from Day 1. Bud is too ambitious for one person. We're going to need an ambitious community behind this framework. • Bud should be able to provide high-level APIs for developers while compiling down to performant low-level Go code for production. • Bud should compile to a single binary. With platforms like Fly.io and Heroku, these days it's easy to not care about this, but I still cherish the idea that I can build a single binary that contains my entire web app and secure copy it up to a tiny server that doesn't even have Go installed. It's still super early days. You can find the the Roadmap on Github: https://ift.tt/7GeNiln . I encourage you to contribute your thoughts. And here's the current documentation for what's already in Bud: https://ift.tt/Ggx9wIM... . Comments are enabled for anyone to chime in. I have big plans for the framework. I hope you'll join me on this journey to build ambitious websites faster with Go! https://ift.tt/m8a1ILk May 14, 2022 at 12:31AM
Show HN: Catchy melodies made with a diffusion-based neural net assistant I've created a diffusion-based neural net generative assistant that makes creating new melodies much easier, even for non-musicians like me. These are meant to be just the catchy "hook" parts of songs, so more work is required to make them into full songs, but this is already handled well by existing products (e.g. there are plugins that can suggest a few possible chord progressions based on the melody and there is even good singing software that I used without any tweaks to make the “voice” playlist: Synthesizer V Studio). This side project turned out to be quite challenging because of how little data there is to train on - several orders of magnitude less than DALL-E or GPT-3 had available for its training, so it required a deep dive into research of new generalization and augmentation techniques and some feature engineering.

Show HN: Wordle in Python using literate programming Hey HN! I wanted to demo TDD with Python, as well as showcase some BDD practices I've been blogging about recently[1]. So I used literate programming to implement Wordle, and rendered the narrative into this "Show HN" webpage. I'm certainly no Knuth, but I'm pretty proud of the result. Proud enough to chance myself to a HN post, and risk HN's mockery and ire: my first "Show HN". I hope this crowd will enjoy this annotated walkthrough of Wordle implementation in Python. Codebase available on Github[2]. Relevant for folks here (though not covered in the main narrative) is how the Gherkin files are listed as Requirements[3] via Sphinxdocs extensions[4] [1]: https://jiby.tech/ [2]: https://ift.tt/QEyMlBj [3]: https://ift.tt/joRrdMQ...

Show HN: Jira to Gitlab Issue Migration Tool $DAYJOB needed to migrate from JIRA to Gitlab due to business reasons (not related to the recent outage), so I wrote this issue migration tool [1] to help us preserve our historical data. This tool will copy issues from various JIRA projects to mirrored Gitlab projects (e.g. A jira project named JIRA-PROJECT1 will have its issues migrated to a gitlab project GL-PROJECT1). The tool also migrates issue comments to Gitlab notes and will recreate the existing issue links. YMMV, but this is working well for us. Comments welcomed. 1: https://ift.tt/G45CWil May 8, 2022 at 05:31AM
Show HN: Weron – A Peer-to-Peer VPN Based on WebRTC Written in Go Hey HN! I just released weron, a P2P VPN that uses WebRTC for transport which I've been working on for the last couple of months. It can create both layer 2/Ethernet and layer 3/IP overlay networks, and the underlying transport layer can be easily embedded to write your own P2P apps with Go. Compared to for example Tailscale, WireGuard and ZeroTier, its much harder to block on a network level and also significantly easier to set up, while not sacrifing much performance. I'd love to get your feedback :) https://ift.tt/I36EAbO May 8, 2022 at 01:18AM
Show HN: I made Ankify that converts notes to Anki cards Backstory: I was in medical school and had to study a ton of materials in short period of time. I came across Anki but always had trouble with making cards. In my mind, making cards should be quick, seconds instead of minutes. My other problem is after making the cards, each card does not really relate to the other. When you study the individual card, your thought process is very random and not cohesive. I wanted to be able to still reference to my notes for big concepts and then use the cards to memorize the details but also for long term retention. Ankify came out of that. At the time, I did not know any programming and paid someone to write a script in Python to convert the cards. Then, eventually I learned Python myself and expanded on the script. I also uploaded the markdown files online so I could view them anywhere ( https://ift.tt/4e2AFHK ). I ran into a wall in making user interface for the program. It was difficult to make good looking cross platform user interface with Python. I gave up on making user interface for a year or two with end of med school and residency. After a while, I went back to see if anyone else had made anything similar. Despite many plugins/programs that makes it easy to make cards, none of them really focused on readability of the original notes. I decided to sit down and learn javascript to help with UI creation. After about 3 years, everything finally came together after I learned Svelte, Tailwind, and Electron. I know Electron is not the most efficient program, but it's what works for me. Also, it's also the feeling of being able to make whatever my mind can think of. It feels really refreshing and empowering. Even making the website for Ankify is a lot of fun. You have to think so much about the presentation, typography, logistics. https://ift.tt/QGjZwKY May 7, 2022 at 07:03PM
Show HN: An Absurdly Compatible Website Hey all, I was inspired by the other thread to make a quick video demo of what an Absurdly Compatible Website may look like when implemented.

Show HN: RFC End Citizen Data Sales Act (California) The sale of personal information by the government is something that has always really bothered me. This is a bill I drafted that would stop the DMV, voter registration, property tax records, and the post office from selling or publishing without explicit user consent. It would also require personal information to be accompanied with the provenance of that data. This way, a user can track down who or what is publishing their data and take action to end their relationship with that company. I would appreciate any feedback, because I am sure I am missing some second and third order effects that this would have.

Show HN: I am building a free version of Strava I recently added a Segments feature to the Hangtime mountain biking app for Android and IOS. If you are familiar with Strava’s segments, this new feature works much the same. For example, you can add a segment to an existing recorded ride by simply defining a start and end point for the segment. Once the segment is created, it will match any new rides, and optionally “back match” all previous rides. If a segment matches a ride, you you will see your time to complete that segment as well as your personal record (PR) and king of the mountain (KOM) for that segment. The KOM represents the best segment time amongst all riders that have matched that segment. You can also open the segment to see your complete history on that segment to gauge how your performance has changed over time. Some screenshots and videos as well as other features at the link below. https://ift.tt/GneaUxl https://ift.tt/GneaUxl May 3, 2022 at 12:01AM
Show HN: Kontxt – Social web layer with CMS and social network Hey, I’m Dave, the founder of Kontxt.io ( https://www.kontxt.io ). Engage directly on the web and save, organize, and share highlights and notes. Follow people. Join groups. And search content. Here’s a 2-minute demo ( https://youtu.be/Th4vaOzuGnU ). It works on desktop and mobile. The web layer is like Google-Doc collaboration on the entire web, and it’s connected to a web app that’s like a combo of DropBox to save and organize your findings, and Twitter/Reddit to share and discover bite-sized article highlights with other people. 1.) The Social Web Layer has rich collaboration features with privacy and share controls: Inline highlights, tags, polls, comments, @mentions, deep-links to anything you add to the page, and navigation between parts. The web layer can be added to any site or PDF with a single line of javascript. This is done with a browser extension, bookmarklet, or added to a page directly by the site owner with the word-press plugin or hard-coded javascript. 2.) The CMS and Social Network lets you organize with folders that have privacy and share controls, a profile with your public highlights, a feed of highlights from people you follow, groups with feeds around topics, and the ability to search your content and what others share publicly. For years, I had a long commute, so I read online a lot–from HN, of course. There’s too much to read everything, and you only know if an article is “worth-it” after you read it. Then it hit me. Highlights! 1.) On the page with navigation, 2.) visible before you open the link, and 3.) to increase quality and relevance, follow and search highlights by trusted people like friends, co-workers, university peers, and industry leaders. There’s too much information and not enough time. Highlights are short, useful, and fast to read. Kontxt.io lets you direct attention to what matters. First, it lets you find quality sources from trusted people, then it lets you focus on the important parts of them. Kontxt basically turns the web into an interactive workspace so you can have rich web interactions with other Kontxt users. Or you can extract highlights into a shareable link and post it anywhere on the web–with analytics for what you share. Highlights are automatically saved to the CMS and based on their privacy settings, may be published to feeds in the social network for others to see. Naturally, you may want to discuss the same site with different people for disparate reasons, so you can create multiple highlight layers on a single site, each with Google-Doc-like sharing, privacy, and authorization controls. It’s now evolved into a general communication and engagement platform for the web. Here’s how Kontxt has been used or where people expressed interest: social news aggregator, productivity, research & planning (generally, and specifically for sales, law, & finance), knowledge-base, training & education, publisher inline-engagement system, etc. Kontxt gets to the point fast. It brings collaboration directly to the web itself and is already part of your natural workflow since it's always with you every click of the way. The social network is unique since it uses highlights to seed discussions. This has many benefits. Highlights mean people have actually read the article, the source is cited, and parts can’t be misconstrued because you have context. It’s also a human filter of the internet. A site is likely worthwhile if someone took the time to highlight it, and if someone found it useful, then someone “like” them probably will, too. Similarly, if someone’s not willing to highlight a site before they send it to you, it’s probably not worth your time. And highlights will increase how many people actually read what you send them because they’re short, useful, and fast to read. I’m excited to share this with all of you. Thanks for your time. Please leave any feedback or questions in the comments. If you try it out, be sure to join the “Hacker News” group. https://www.kontxt.io May 2, 2022 at 11:45PM

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

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.

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: 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! Some examples: * A comparison of 2018 data for the "Professionals" job category across the Information industry, Facebook, and Netflix: https://ift.tt/ETluBLX... * A comparison of 2018 data for all job categories across the Finance and Insurance industry, BlackRock, and PayPal: https://ift.tt/jUz4JtS... * A comparison of 2018 data for the "Exec/Sr Officials & Managers" category across the Professional, Scientific, and Technical Services industry, Accenture, and Nvidia: https://ift.tt/LNswfK6... If there's a company with EEO-1 data that you would like to see, consider submitting a URL via this form: https://ift.tt/GUcoKCA Let us know what feedback you have for us! For those who are curious: at runtime, Employees.fyi uses normalize.css and the Open Sans font. They are hosted with the website. https://employees.fyi April 17, 2022 at 11:32PM
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. You can find the tool here: https://ift.tt/NgBcVnh Comments, questions, and suggestions are more than welcome! I wish you all a happy Easter Weekend!

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. You can, however, make stacks online and let others see them. Free, no ads, no personal information, you are not tracked, just a fun project. https://ift.tt/BtEg8xZ April 15, 2022 at 08:49PM
Show HN: Fast,Compiled deep-learning based modules for inferencing on CPUs Hi HN,I am Anubhav from RamanLabs.We have been developing dedicated modules based on deep-learning for purposes like face-detection,object-detection,pose-estimation etc. We hope to make it easy for developers,hobbyists to integrate such functionalities into their existing app/pipeline at the cost of a few milliseconds.All our modules run end to end in super-realtime even on consumer-grade CPUs[0]. For now we provide only Python based API. We provide Demo for each of the modules to allow testing for your desired data distribution.We also have a blog[1] where we hope to add more technical details about the framework used to develop these modules. The framework used to develop these modules is completely written in Nim language.We wrap existing ops implementations from libraries like ONEDNN and write our own code where we cannot find one or existing implementation is not good enough,mainly for preprocessing and postprocessing code.Having full access to framework code and being written in a high level language allows us to port newer architectures and optimize them quickly. We would love to hear your feedback on our attempt. [0] Quad-core Cpu with AVX2 instructions. [1] < https://ramanlabs.in/static/blog/index.html > https://ift.tt/NutIY4B April 14, 2022 at 11:38PM

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.

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: 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.

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!

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
