Show HN: A good excuse to explore that side project idea https://ift.tt/2HJvd8R

Show HN: A good excuse to explore that side project idea If you're like me, you have at least a half-dozen (half-baked) ideas for side projects sitting on your "idea shelf" waiting for the right opportunity to come along and give you that spark to get started. At my day job (Bridge.Academy), we found that many of the incoming developers entering our program shared the same experience so we decided to do something about it and formalize the process of picking up a new technology you are trying to learn and applying it through a side-project with a program we're calling "The Bridge Tournament". It's designed to give you that extra bit of motivation to take your side project idea off the shelf, pick up a brand new technology and start building the damn thing. Here’s how it works Each month new applicants to join Bridge.Academy participate in a tournament in order to demonstrate their ability to quickly pick up new skills through working on a project of thei...

Show HN: E-Nguyen – Music Visualization in Rust https://ift.tt/2FzXLzn

Show HN: E-Nguyen – Music Visualization in Rust Only Linux can run it so far until more sound servers are supported. (Contributors will be pampered!) https://ift.tt/2utFNsf https://ift.tt/2HTgiIy Just got done publishing 0.1.2 and have a pretty good feel for what I want in making an FFT derivative for streaming / logarithmic display. One of the projects (Trello things) is still pretty much a rough draft, but it outlines how I'm intending to go at the architecture. In short, I want to support metamaterials for generic 3D content to be Nguyen-ified and lots of composition. I learned Rust & Vulkan for this project and look forward to actually getting good at both of them to start landing more PR's in upstream. March 25, 2019 at 05:23PM

Show HN: shed – a self-hosted collaborative editor with code running + replays https://ift.tt/2CCcPKZ

Show HN: shed – a self-hosted collaborative editor with code running + replays demo: https://ift.tt/2FyM6B6 this past january, I spent time trying to figure out how to work with people remotely on problem solving. For a while, we tried out codepad, pramp and google docs, but they all had minor problems. I spent a couple weeks looking through differential sync algorithms (diff patch match, CRDT and OT) and eventually found a good demo using ot.js - shed was built on top of that demo, with a couple added features: running code through docker and ability to watch replays of a session. I thought I'd share it here for others who are looking for self-hosted collaborative editors. thanks! March 25, 2019 at 04:24AM

Show HN: Customizable DuckDuckGo Search Bangs Service https://ift.tt/2OeJqLF

Show HN: Customizable DuckDuckGo Search Bangs Service I love DDG !bangs so much, that I kept finding myself in need of custom search !bangs... So I built them! I absolutely love DDG's search !bangs! ... even more than their stance on privacy. If you've ever found yourself wishing for a custom search !bang you're in the same boat as me :) Sure, sometimes submitting a public !bang is the way to go... But not always. Maybe you want to override the default !weather or you want a custom !bang for an internal tool used by your employer.

Show HN: Songcraft – Online Songwriting Platform and Guitar Tab Builder https://ift.tt/2JnIN3s

Show HN: Songcraft – Online Songwriting Platform and Guitar Tab Builder Hi HN! I'm Gabe, the creator of Songcraft ( https://ift.tt/2Oe8G4J ). I recently dove headfirst into songwriting, and I quickly grew frustrated with my process. I found songwriting difficult enough without having to wrangle a mess of different tools, and there's no great solution to build chord sheets and tabs (unless you love pure text input). So, I built Songcraft - an online songwriting platform and tab builder. The drag-and-drop editor makes it easy to jump from chords to lyrics to melodies. I added a chord progression generator and chord recommendation engine to ensure the ideas keep flowing. The integrated tuner, rhyming dictionary, metronome, and audio recorder allow you to stay focused without distraction. A few months ago I shared the beta on Hacker News and got some incredibly helpful feedback and some amazing beta users. Since then, I've revamped the product and made a ton of improvements and...

Launch HN: Cliperado – Automatically take screenshots of your whole service https://ift.tt/2FhJyWm

Launch HN: Cliperado – Automatically take screenshots of your whole service Cliperado ( https://cliperado.com ) is an online tool to automatically take screenshots of your service and keep the shots up-to-date in your help guides. The idea for Cliperado came when we were creating visual step by step guides, to reduce our support volume, for an other service. We needed about 200 clips for each language. It took so much time to create just a few. I was pulling my hair out. Especially with the thought of having to check all the clips for changes in a month from now, manually. You’ve probably seen a few online tutorials with outdated and confusing screenshots. You probably have a some outdated screenshot in your own manuals. I get that, it is just too much work to keep these updated manually. So we created Cliperado, to automate this. How Cliperado works. Cliperado takes full page retina screenshots of your online service. It can take screenshots of pages behind a login screen as well, by ...

Launch HN: Nabis (YC W19) – Cannabis Shipping and Logistics https://ift.tt/2uaj5VN

Launch HN: Nabis (YC W19) – Cannabis Shipping and Logistics Hi HN! We’re Vince and Jun, the founders of Nabis ( https://ift.tt/2UKLnlz ). We are building a software and infrastructure solution to ship legal cannabis products for brands to licensed dispensaries throughout California. About two years ago when the legalization of recreational cannabis was pending in CA, we were excited as consumers to be able to try out a variety of products without having to get a medical card. While we knew that many more brands were coming to market, we discovered that there was a lack of supply chain infrastructure to support the growing demand. We started out driving our own personal vehicles across the state to help a friend ship his products just to learn more about how the supply chain was set up. We learned that brands were still predominantly self-distributing, since you can’t just Fedex cannabis products due to compliance restrictions. Apart from shipping, the lack of secure warehousing space, ...

Launch HN: Bottomless (YC W19) – Coffee Restocked with a Smart Scale https://ift.tt/2Hpu7yV

Launch HN: Bottomless (YC W19) – Coffee Restocked with a Smart Scale Hello, HN! We're Michael and Liana, co-founders of Bottomless ( https://bottomless.com ) Bottomless automatically re-stocks coffee using a smart scale. Users leave their coffee on the scale, then we detect the perfect time to trigger re-orders. We ship the scale for free when customers buy their first bag. We met in college, and bonded over talking about businesses we could build together. You could say we've kept in touch since then: we're now married. Bottomless was born out of our frustration managing our household stock levels. We always seemed to be running out of one thing or another. When we thought about it, we realized that restocking was a universal problem. But if this was such a big problem, why was there no great solution? Subscriptions should be a solution, but they don’t work well for items that aren’t used on a set schedule. It seemed that if we could capture data on usage and stock levels ...

Launch HN: Point (YC W19) – First Debit Card with Points https://ift.tt/2W8XBon

Launch HN: Point (YC W19) – First Debit Card with Points Hi HN community, We’re Patrick, Kenan, and Sid, the founders of Point ( https://ift.tt/2u7QyA9 ), a consumer digital bank focused on rewards. After being fed up with the poor customer experience and tactics of traditional banks, we did some digging into why we put up with our own subpar banks. We've discovered that the way most people end up with their current bank is by default (ex: parents set it up for them), rather than by choice. The complete opposite was the case for credit cards; credit cards were actually chosen based on their qualities. We began to wonder why a solution that combined the rewards and benefits of a credit card, with the simplicity of a bank account didn’t exist. After extensive research and testing of various existing products, we determined that everything came up short for our personal needs. That was the problem. Whether it was simply the lack of a clean mobile user experience, or rewards that were ...

Launch HN: Nala (YC W19) – Internet-Free Mobile Payments App for Africa https://ift.tt/2JeCyiB

Launch HN: Nala (YC W19) – Internet-Free Mobile Payments App for Africa Hi HN! I’m Benjamin, one of the co-founders of NALA ( https://www.nala.money ), an application that simplifies the process of making mobile payments for our users in Africa. My co-founder Sam and I first met back in 2016 while I was working at the Bill and Melinda Gates Foundation (focusing on financial services in Africa), and he was earning his Ph.D. in computer science at the University of Washington (researching mobile money security in Sub-Saharan Africa). As you may know, the way that mobile payments are made in many developing markets is quite different from how they're made in the rest of the world. In much of Sub-Saharan Africa, people make payments using mobile money, an electronic wallet service that is typically tied to a user's cell phone carrier and sim card. Using a 39-46 digit sequence of short codes (i.e. dialing a code such as 150 30, waiting for a screen to pop-up, dialing another code an...

Show HN: C++17 In Detail, a book that will move you from C++11/14 to C++17 https://ift.tt/2UBd3sN

Show HN: C++17 In Detail, a book that will move you from C++11/14 to C++17 Hi! Last year in August I've released my first self-published book. C++17 In Detail Available at Leanpub: https://ift.tt/2LgTiRU Keeping up with the latest changes in the language is quite hard. C++ moves quite fast recently, and there are many exciting features added with each iteration. The book shows all the significant changes in the language and the Standard Library. The chapters are much easier to grasp than reading reference pages or the Standard itself. It's a great guide for any C++ developer who knows a little about C++11/14 and wants to move forward. In August the book was 90% ready, and I worked since then to write the last chapters and improve the content. In March it reached finally the 100% status :) I would appreciate any feedback! You can also ask me about the publishing process. March 14, 2019 at 07:47AM

Launch HN: Travelchime (YC W19) – doc for travel planning with friends https://ift.tt/2O6xdso

Launch HN: Travelchime (YC W19) – doc for travel planning with friends We're Peter and Harry, and we're building Travelchime ( https://travelchime.com ). Travelchime is like Google Docs for planning vacation travel with your friends' recommendations. It lets you add places and attractions you're looking to visit to a doc, export them to Google Maps, and collaborate with your friends who've been there or are going there with you. We used to plan our trips using Google Docs and Sheets, but it was a pain. We'd write the documents, then had to add the same places to a map for when we're on the trip. We also often sent these out to friends who asked -- there's nobody whose recommendations you trust more than your friends -- but it's hard to find which friends have these docs. We built Travelchime to solve this. With Travelchime, you can: 1. Add all the museums, restaurants, and places you're staying/want to visit to a doc on Travelchime, and see them ...

Launch HN: Superb AI (YC W19) – AI-Powered Training Data https://ift.tt/2O2N771

Launch HN: Superb AI (YC W19) – AI-Powered Training Data Hi HN, I’m Hyun, one of the co-founders of Superb AI ( https://ift.tt/2J9xifT ) in the YC W19 batch. We use AI to semi-automatically collect and label training data for tech companies, and help them implement machine-learning based features faster. Almost all the magical AI features that we see are actually built using training data powered by humans. Companies build software tools and farm out to a bunch of people to click and type things repeatedly to label the raw data. That's how training data is made, and that’s a very large portion of what an AI is, up to this point. It has worked well up to now, but the process is not very fast and often prone to error. Moreover, the size of training datasets has increased exponentially over the past few years, as it almost guarantees a higher AI performance. AI engineers are now handling datasets as large as tens of millions of images, and thus there is a great need for a better way t...

Show HN: Building computer labs in schools in Africa https://ift.tt/2HsXUpH

Show HN: Building computer labs in schools in Africa My name is Nelly Cheboi. I am the co-founder of https://ift.tt/2UuEmEZ , an organization that fosters a more technologically literate Africa by building computer labs in African schools. I was raised in Mogotio, Kenya, in abject poverty. At nine years old, I collected wild vegetables on my way from school to cook for my younger sister. The only way I knew out was by studying. So I studied. I studied hard. And I ended with a full-ride scholarship to Augustana College, IL. I was majoring in Chemistry before I discovered computer science my junior year of college. I loved it. With only three semesters left, I decided to get a degree in it. I also built a school with the aim of fostering digital literacy. I doubled down on my work-study program, got some donations from friends and four months later I launched Zawadi Preparatory (www.zawadiprep.tech). We admitted 30 kids at its launch in January 2016. Barely 3 years later, we are at 150 k...

Launch HN: Axdraft (YC W19) - Legal documents for startups in minutes https://ift.tt/2UwzXS1

Launch HN: Axdraft (YC W19) - Legal documents for startups in minutes Hi HN! We are Yuriy and Oleg, founders of Axdraft ( https://ift.tt/2XQ5ksW ). Axdraft offers free legal documents for startups. We have built Axdraft, because we believe that sometimes founders don’t need 20-page ironclad contract, 2 weeks of negotiations and detailed explanation of all risks. On early stages you just want to have a good, balanced agreement fast to move the deal forward while it's hot. The biggest difficulty here is that lawyers push us to perceive contracts as unique and, therefore, not possible to automate. Usually, by saying unique, they mean that there are 20-50 possible variations of a clause in the contract. We are a team of brothers, who combine legal and tech expertise, Yuriy was a lawyer for almost 8 years at one of top law firms in Europe and when he started noticing that even the most complex legal transactions have many patterns, he reached out to his brother Oleg, who at that time wa...

Launch HN: MedCrypt (YC W19) Medical Device Cybersecurity https://ift.tt/2O1RFdW

Launch HN: MedCrypt (YC W19) Medical Device Cybersecurity Hi HN! We're Eric and Mike, founders of MedCrypt ( https://ift.tt/2u3aST7 ). Our mission is to make it easy for healthcare technology companies to build cybersecurity features into their products. I (Mike) was previously a product manager at a medical device company and witnessed an increasing concern about the security posture of Internet-enabled medical devices. This culminated in a couple of big device companies needing to issue recalls for their medical devices due to cybersecurity vulnerabilities. It struck me as an interesting transition from cybersecurity being a compliance requirement and instead a concern when managing patient safety. Being concerned about the lack of resources available to implement data security properly, or at all in some cases, we decided to build a platform that helps healthcare software and medical device companies properly integrate data security features into their products, while actively m...

Launch HN: AmpUp (YC W19) – A reservable electric car charging network https://ift.tt/2NZjIuy

Launch HN: AmpUp (YC W19) – A reservable electric car charging network Hi HN, This is Tom from ampUp ( https://ampup.io/ ). We're building a reservable electric car charging network out of shared private and home chargers. As a Nissan Leaf driver without a home charger, charging has been almost a daily headache for me. For many commutes and trips I have to ask myself, should I drive my Leaf, use Uber, take public transit, walk really far, or just not go? This is due to the walk-in-only model of the public charger, which results in unpredictable availability. Worse, public charging is growing at a slower rate than EV adoption, and the range estimators on EVs are no better than a 10-day weather forecast. I used the Plugshare app and it helped some, particularly the couch surfing style of charging where I arrange a 2 hour slot with some home charger hosts. When it worked well, it took out the unpredictability and therefore anxiety. However, it doesn’t always work well. Many times host...

Launch HN: Mudrex (YC W19) – Automated Trading Without Code Hello, HN! We're Rohit, Edul, Prince, Alankar and Snehil. We’re building Mudrex ( https://mudrex.com ). Mudrex helps traders automate their trading without having to code and spend a lot of time and money building infrastructure. Though we have started with cryptocurrency trading first, our goal is to help anyone who wants to get into automated trading or investing across any asset class. We had been trading cryptocurrencies for some time and were not able to track trading opportunities across 1000s of currency pairs for 24 hours a day and 7 days a week. We thought of automating our trades, but faced challenges like being unable to access historical data, building a testing framework to test strategies on historical or live data, and maintaining connections and orders on multiple exchanges. Also, since it was all coded we were not able to quickly iterate on trading ideas, since for simplest changes we had to dig into code ...

Launch HN: GoLinks (YC W19) – Internal short links for teams https://ift.tt/2NPyFiF

Launch HN: GoLinks (YC W19) – Internal short links for teams Hello HN! We’re Jorge, Kevin and Sean and we’re building GoLinks ( https://www.golinks.io ). GoLinks is a platform that allows you to easily manage and share links by letting teams create a short link for any internal URL within a company. These links are easy to remember and share, so you don't have to bookmark or copy and paste them in emails. Each day we use and share hundreds of links to get our jobs done, without considering how long it takes to access and share these resources. It’s one reason why many of us leave tabs open in our browser: we don’t want to spend the 5 to 10 steps to navigate back to that important page. With GoLinks, you’ll be able to deep-link directly into any application with just a simple keyword entered into your address bar. This allows links to be conversational. For example, one employee can create the keyword “go/review” to point to the annual review page in Workday. Later in a meeting, tha...

Launch HN: Cosmic JS (YC W19) - API-first drop-in replacement for WordPress Hey HN, I'm Tony, one of the cofounders of Cosmic JS (YC W19) ( https://cosmicjs.com ). Cosmic JS is a drop-in replacement for WordPress that can power content for any website or app. We provide a web dashboard to create content and API tools and resources (REST and GraphQL) to integrate content into any new or existing project. Commonly referred to as a "Headless CMS", this eliminates the need to build and maintain your own CMS infrastructure. For a monthly fee, you use our CMS infrastructure and can focus on what really matters: building great products and user experiences. My cofounder Carson and I met at a digital agency where we built and managed WordPress websites. We noticed that lots of development time was spent building and maintaining the CMS itself, sucking time away from core application development. Plus we encountered the same CMS problems over and over: automatic updates caused sit...

Launch HN: The Juggernaut (YC W19) – A Publication for the South Asian Diaspora Hi HN! I’m Snigdha, founder of The Juggernaut ( https://ift.tt/2Tz5fur ), a subscription publication for the South Asian diaspora. We charge <$5/month for original stories on South Asia and its people. I’d love your feedback — new subscribers get a free week trial :) I’m Indian-American and grew up in New York. Being Indian wasn't cool growing up. Western media mostly focused on South Asia's poverty (Slumdog Millionaire) or stereotypes (Apu, taxi drivers). That started to change as I grew older. I saw more South Asians in the news — from those in spelling bees, which I used to participate in, to presidential candidate Kamala Harris, to tech CEOs like Sundar Pichai and Satya Nadella. I realized I didn’t know what was going on in the region or with South Asians nationally, let alone in my own city. My mom would forward me news on WhatsApp and I couldn’t talk to her about it meaningfully. I also fou...

Launch HN: Dockup (YC W19) – On demand staging environments for dev teams https://ift.tt/2EPD9Da

Launch HN: Dockup (YC W19) – On demand staging environments for dev teams We're Emil and Yuva, co-founders of Dockup ( https://getdockup.com ). Dockup spins up on-demand environments so engineering teams can quickly test their code changes. When you open pull requests, Dockup creates disposable environments automatically and delivers URLs to your chatrooms; engineers don't have to wait their turn to manually deploy to a staging server for testing their code changes. Anyone in the team can then click on these URLs and preview features before merging pull requests. Because each environment has all the services in the tech stack, it lets you catch bugs which usually happen only in production. My co-founder and I were colleagues at our previous job (for ~6 years) where we worked as consultants, mostly working on Rails, React and Elixir projects and had the luck to work closely with many engineering teams. We often saw that teams would slowly lose confidence in their code as their c...

Launch HN: Saratoga Energy (YC W19) Better Carbon Nanotubes from Carbon Dioxide https://ift.tt/2XDCHPF

Launch HN: Saratoga Energy (YC W19) Better Carbon Nanotubes from Carbon Dioxide Hi HN, I’m Drew, founder of Saratoga Energy ( https://ift.tt/2Tce0v7 ). We make better carbon nanotubes at one-fifth the price. Carbon nanotubes are a form of nano-scale carbon fibers (5,000X thinner than human hair) with remarkably high strength, electrical conductivity, and thermal conductivity properties. This makes them useful in a variety of commercial applications. Lithium-ion batteries designed for electric cars already use carbon nanotubes to reduce heat generation during charging and to improve electrical conductivity. This results in faster charging and improved battery life. However, the cost is so high ($300/kg) that battery manufacturers are forced to use the minimal amount, rather the optimal amount. Our breakthrough in manufacturing cost enables battery manufacturers to use the optimal amount, allowing electric cars to safely recharge in 10 minutes or less. This could give electric cars the b...
