Launch HN: Pillarlus (YC W20) – Automatically create construction blueprints https://ift.tt/2yet5m3

Launch HN: Pillarlus (YC W20) – Automatically create construction blueprints Hey HN, we’re Naman and Rushil, founders of PillarPlus ( https://ift.tt/3dHyOBg ). We build software to automate the creation of construction blueprints. Specifically, our software generates engineering blueprints for air conditioning, ducting, fire, electrical, and plumbing services over the floor plan of the building. MEP (Mechanical, Electrical, and Plumbing) designs are a set of 15 technical drawings. We got started in India and are currently operating there, but MEP is standard enough that the software can apply to Western markets also, given that we have incorporated international building codes. Architects and contractors hire consultants, who still design the building manually. Complete dependence on human effort results in a process that is slow, error-prone and unreliable. Also, the number of consultants is limited resulting in higher fees, long delivery times and difficulty accessing the services. Rushil started practicing architecture and had troubles dealing with the available MEP firms for his own projects. Naman built an optimization software for the Indian Railways. We’ve been friends for 13 years, and often discuss our problems and achievements. Naman hacked a prototype for plumbing drainage plans that worked perfectly over Rushil’s project, and got us excited about the possibility of such a software. Our software takes in the floor plan as the input, understands the building and designs the MEP services like an engineer would. A month of engineer’s work gets cut down to a day. We require artificial intelligence algorithms to decipher the floor plan, constraint modelling techniques to encode building codes, routing methods to create pipe paths and optimization algorithms to minimize material wastage. The software even calculates bill of materials with project cost estimates. It is important to note that MEP accounts for 25% of all project costs! Since the quantity of materials is huge, selecting the right items and vendors is a challenge in an unorganized sector like construction. We recommend what products to install and which brands to choose, as per geographic locations and availability. The input to our software is the building’s floor plan. The floor plan gives us complete data of the building, with which we can do a lot more. We can generate structural blueprints, 3D models, and create interior design renders! We're eager to hear feedback and answer questions. Do share your experiences from the construction industry, and your opinion on the use of software to make construction work more efficient.

Show HN: Soft-launch, first page on HN – here are the numbers https://ift.tt/2Uyb8rA

Show HN: Soft-launch, first page on HN – here are the numbers [1/2] Thursday evening (Mar 26) we made a soft launch for https://ift.tt/2UmnXFb (a UI website that I built for my wife) The goal was to get some feedback, fix bugs and get about 30-40 subscribers in the mailing list, to see how the newsletter performs. The launch went better than expected, and the feedback was generally positive. Below are some numbers for those interested. I posted it to 4 channels, IH, HN, Reddit and Twitter. It was best received on HN with 203 points, it made it in the top 10, and it stayed on the front page for a good while. Reddit also surprised me, I posted in r/SideProject and got 26 upvotes and only positive comments.. ? That is so not what I expected from reddit... Was very pleasantly surprised to say the least. Analytics: - 6.659 Users - 6,757 New Users - 7,906 Sessions - 19,125 Page views - 61.81% Bounce Rate - 10.1% Returning Visitors Users timeline: - Mar 24 - 0 Users - Mar 25 - 4 Users [Soft Launch] - Mar 26 - 2458 Users - Mar 27 - 3693 Users - Mar 28 - 706 Users - Mar 29 - 186 Users - Mar 30 - 190 Users As you can see, there’s been a spike and seems like it’ll stagnate around ~150, but it remains to be seen. It might dip even further. Newsletter: - 546 Subscriptions - 52.1% Open Rate - 6.7% Clicks - 7 Unsubscribes Slack Community: 40 Members. Interestingly enough, the Slack ad only received 30 clicks total. This means most users came through the welcome email, which has a slack community ad included. Ad Performance: - 35744 Impressions - 836 Clicks on Website - 8 Clicks in Newsletter March 31, 2020 at 02:25PM

Show HN: Security Advice for Regular People https://ift.tt/2QVySn9

Show HN: Security Advice for Regular People I had the idea to create a dedicated web page containing basic, easy-to-understand digital hygiene advice. So if a friend or relative asks you for advice on securing their digital lives, you can simply give them a link and hopefully they'll share it with their friends too. Hosting is on GitHub pages; just a single, semantic, accessible HTML file. I just made this today, so contributions are welcome, especially right now. I am not a security researcher, so if anyone finds an issue with what I've written in this first draft, or thinks some other point deserves mentioning, please tell me either here or in the form of a GitHub ticket or pull-request. Project goals and contribution guidelines are available in the readme. I'm also thinking about getting a custom domain name for it, but I'm not sure what has the right balance of sounding trustworthy and being available/affordable. So let me know if you have any ideas on that front as well! https://ift.tt/2WNZz0S March 30, 2020 at 02:21AM

Show HN: Create a free photo sharing social network for your Startup https://ift.tt/3arozyJ

Show HN: Create a free photo sharing social network for your Startup Consumers have become numb and cynical of most brands on social media. The constant barrage of highly-curated, highly-targeted, and polished posts are turning people away from these platforms. More people are taking refuge in online communities and messaging apps devoid of ads and self-promotion. So, how do brands reach these savvy and wary consumers in an authentic way on social media? Authenticity. Like consumers, brands worry about the content they share with the larger global audience. They must promote photos and videos that appeal to their core customers without alienating or offending others. Needless to say, brands also need channel(s) on social media to share most comfortably. Diverse and inclusive companies are starting to build private communities on social media where they can share more casually and engage their followers. In these private communities, brands are also able to crowdsource customer-generated content and receive feedback from their fans. All of this helps build trust and loyalty among consumers. Our startup, Pixz, is focusing on building channels for individuals and companies to share together. Pixz (https://pixzapp.com) is a private photo sharing app for groups and events that allows people to crowdsource photos in real-time without hashtags and uploads. Main Features: 1. Create unlimited private groups for any occasion and/or audience 2. Take photos that share instantly & privately within group 3. Crowdsource photos from guests at events in real-time 4. Upload up to 5 photos at a time with separate captions 5. Schedule events to limit posts before or after an event 6. Share and download full-resolution photos from group members 7. Comment and like photos people share like other social networks 8. Discover groups and events near you Pixz is a free download from the app stores.

Show HN: ActionsPanel – Manually Trigger Your GitHub Actions https://ift.tt/2UDbnjO

Show HN: ActionsPanel – Manually Trigger Your GitHub Actions Hi all! I wanted to share a small project that I've been working on with a buddy. https://ift.tt/2QYkkSQ One of the problems that currently exists with GitHub Actions is the fact that there is no way to easily trigger your Actions unless you cause some kind of GitHub event. This could be pushing a new commit, or creating an issue on a repository. But if you just want to run an arbitrary action, there's not currently a good way to do that. This is a well known feature request: https://ift.tt/2UnIglF GitHub somewhat recently added an API for `repository_dispatch` which is an available trigger for a GitHub Action. There are many blog posts that explain how you can create a Personal Access Token to send your own `repository_dispatch` via some curl command or postman request. For example: https://ift.tt/2vVM3gx ActionsPanel uses this same API but does so with a GitHub App token so that you don't need to worry about managing your own PAT. This also makes it much easier to trigger your actions across teams with multiple people. Then you don't need to share the PAT with each other or each create your own PATs. You configure your buttons with a declarative yaml file that you leave in the repo, and ActionsPanel will read that file and dynamically create your UI for you to trigger your actions. We'd love to get your feedback on this project. It's very simple still but solves the core problem of triggering your actions. If you do have feedback or any questions, feel free to post in this thread, or email us directly at support (at) actionspanel (dot) app Looking forward to your feedback! March 28, 2020 at 08:03PM

I have been using this program to generate my own tumblelog, https://plurrrr.com/, which has been up and running for over a year with daily posts (please check it out). It's a good example of how a blog generated with the program looks. The software comes with 10+ templates so you are not stuck with the same look as Plurrrr.

Show HN: I Made an Event Countdown App in React Native https://ift.tt/2wv0dFU

Show HN: I Made an Event Countdown App in React Native I recently created an Events Countdown app for iOS. Basically, user can create event like Birthday, Anniversary, ... and the app will show a countdown time until or since the event. User can also add reminder days, weeks, months before or after the event. It's not shown in the video but the user can choose different display mode like: List, Grid or Carousel and sizes,... This is my first time trying this business model my apps. It's free to use. You can create unlimited number of events, reminders, you can switch between dark/light theme... All the core features of an Event Countdown apps are free. But there are interstitial ads after the user created an event once in a while. (using facebook audience network and google admob). Some premium features like layouts, online gallery, cloud syncing,... are unlocked through a subscription monthly or yearly. I created the project with [typescript-react-native-starter](https://ift.tt/2JhyVFu). I also tried to contribute some open-source components like: - [react-native-easy-icon](https://ift.tt/2UAlcPA wrapper component of react-native-vector-icons to use icon easily - [react-native-unsplash](https://ift.tt/2WH879A The online gallery feature that you see from the video use directly this component. It's basically a photos browser using the unsplash api. - [react-native-store-rate](https://ift.tt/2JhS0r7 I'm still testing this so I don't recommend you to use All of my components above are written in typescript so it's kinda self-documented, I didn't have the time to update the documentation so PRs are welcome. You can download it here: https://ift.tt/33LRpaz I would love to hear feedbacks. Thanks. March 26, 2020 at 04:03AM

Show HN: Panther v1.0 – Open Source, Cloud-Native SIEM https://ift.tt/2UgMJGM

Show HN: Panther v1.0 – Open Source, Cloud-Native SIEM Hey HN, My name is Jack Naglieri. I’m the founder of Panther Labs - an SF-based cybersecurity startup. Prior to Panther, I was an engineering manager at Airbnb. Before that a security engineer/analyst/forensic analyst. Today, I’m excited to announce Panther v1.0, an open source, cloud-native SIEM: https://ift.tt/3akamns Teams can use Panther as an alternative to traditional SIEMs like Splunk. Panther is the culmination of our team’s experience building security tools at scale, including StreamAlert at Airbnb and critical internal monitoring systems at Amazon. Panther runs entirely on serverless to enable small teams to detect threats at scale. Our backend is Golang and our frontend is React/Typescript. Panther is also self-hosted and uses Python3 for flexible detections. At a high level: - Panther receives security logs - Panther baseline scans cloud infra and determines security posture - All data is saved to your data warehouse (powered by Athena/Glue/S3) - Alerts are dispatched to your team via Slack, PagerDuty, etc - Automatic remediations can also be applied to fix infrastructure Panther v1.0 includes support for: - Analyzing logs from AWS, OSS tools such as Osquery, OSSEC, Suricata, and more - Threat hunting on all your security data with standardized fields (IPs, domains, etc) - Real-time cloud configuration monitoring - 150+ built-in detections - A UI for creating, updating and tuning detections To get started: - Quick-start: https://ift.tt/2ybIrbf - Read our v1.0 announcement: https://ift.tt/2QMywPB - Register for our webinar tomorrow: https://ift.tt/2QLVIh0 You can also find us on Slack (https://ift.tt/2wFfofs), Twitter (@panther__labs), and Github (github.com/panther-labs/panther). We’re happy to answer your questions. Just drop a message here. Thanks! We also send our best wishes to those affected by COVID-19 March 25, 2020 at 09:58PM

Launch HN: Riot (YC W20) – Phishing training for your team https://ift.tt/2QIueZL

Launch HN: Riot (YC W20) – Phishing training for your team Ahoy Hacker News! I'm Ben, founder of Riot ( https://tryriot.com ), a tool that sends phishing emails to your team to get them ready for real attacks. It's like a fire drill, but for cybersecurity. Prior to Riot, I was the co-founder and CTO of a fintech company operating hundred of millions of euros of transactions every year. We were under attack continuously. I was doing an hour-long security training once a year, but was always curious if my team was really ready for an attack. In fact, it kept me up at night thinking we were spending a lot of money on protecting our app, but none on preparing the employees for social engineering. So I started a side project at that previous company to test this out. On the first run, 9% of all the employees got scammed. I was pissed, but it convinced me we needed a better way to train employees for cybersecurity attacks. This is what grew into Riot. For now we are only training for phishing, but our intention is to grow this into a tool that will continuously prepare your team for good practices (don't reuse passwords for example) and upcoming attacks (CEO fraud is next), in a smart way. Your questions, feedback, and ideas are most welcome. Would love to hear your war stories on phishing scams, and how you train your teams! March 24, 2020 at 09:25PM

Launch HN: Taiv (YC W20) – Replace TV commercials with content people care about https://ift.tt/33QD2Cd

Launch HN: Taiv (YC W20) – Replace TV commercials with content people care about Hey HN! We’re Noah, Avi, and Jordan from Taiv ( https://www.taiv.tv ). We make a box that lets sports bars and other businesses replace live TV commercials with content their customers actually care about. A year and a half ago, I was sitting in a local bar and saw a commercial showing that the same beer I was drinking was cheaper across the street. The place I was in had other drinks on specials for way cheaper and great happy hour food, but they didn’t have an effective way to tell me about it. I ended up walking away feeling ripped off when I could have left a happy customer if they had been able to more effectively make me aware of their specials. It got me investigating how businesses communicate with their customers. I found out that half of all restaurants close within a year and that one of the most common reasons they fail is because they’re unable to educate their customers about everything they offer and what events they have coming up. We built Taiv to give business owners a way to communicate with their customers, by showing content during commercial breaks on the TVs people are already watching. Taiv uses custom hardware that lets us analyze the cable box’s video output in real-time. It also lets us switch between passing the content through, or showing videos from another input. But it turns out that a harder part of the problem is the analysis for classifying video. We compute a bunch of different heuristics and use the combination of their outputs to classify video as either a commercial or content. For example, one of our heuristics looks at average color balance over small periods of time. When the color balance shifts significantly, it indicates that a scene has changed. We use a bunch of other similar heuristics, which in combination, allow us to classify the stream with good accuracy. Some of our customers have increased their sales by thousands of dollars a month. It also makes the experience a lot better for their customers. TV commercials are annoying and loud, and we replace that with relevant and non-intrusive content and music. Some of our customers even use the commercial breaks to show funny videos without any advertising at all. Not all of our customers are restaurants. We also work with car dealerships, car washes, hotels, and gyms to give them control over what they show and help them educate their customers. One of the biggest challenges we’re facing is that we’re getting the most traction from larger enterprises, but are having trouble really connecting with smaller businesses. We think the product could be really valuable for them, especially since they don't usually have as much marketing reach. But we’re having trouble portraying the value of the system when they can’t track how it affects their revenue nearly as accurately. We’d love to hear the community’s experience and ideas in this area, as well as any questions or feedback! March 23, 2020 at 09:51PM

Launch HN: Nextmv (YC W20) – Developer-friendly logistics algorithms https://ift.tt/2QtNAla

Launch HN: Nextmv (YC W20) – Developer-friendly logistics algorithms Hey HN! We're Carolyn and Ryan, founders of nextmv ( https://nextmv.io/ ). We help developers build and test logistics algorithms faster. These are things like routing delivery vehicles, assigning nurses to patients, and managing supply chains. We used to work in systems engineering and operations research on big government projects, including missile simulations and airport runway management. A few years ago, we pivoted to working on food delivery at Zoomer (YC S14) and later Grubhub. It turned out that making on-demand pizza and taco delivery efficient and reliable required the same optimization and simulation techniques, but in real time. Real-time routing and assignment problems have a number of interesting characteristics that make them challenging. For example, they follow business rules such as pickups preceding deliveries, time windows for deliveries which may or may not be violated, and driver capacities. Their inputs are constantly changing. They can get very large (1000s of orders, 100s of drivers). And they require high-quality solutions in seconds. People usually think of NP-hard problems like the Traveling Salesman when routing and dispatch optimization is mentioned, and we do have to solve those. But the biggest challenges turn out to be ones that are more familiar to the software engineering community. There is no easy equivalent to the software unit test for techniques such as Integer Programming and Constraint Programming. And integration into modern software stacks is nontrivial. In the end, we had to build new tools so we could work faster. Traditional dispatch and scheduling algorithms take months to develop, integrate, and test. That is a problem when businesses change rapidly. This is happening in delivery, which has exploded over the last few years and is likely to only get bigger. Existing tools require domain experts to translate business rules into models. This makes organizations unable to keep pace with change. During our research into appropriate techniques, we learned about Decision Diagrams ( https://ift.tt/2WDVOev ). DDs represent optimization problems as the search for a shortest (or longest) path over a layered, directed, graph. They are state-based, have few restrictions on problem representation, and can outperform other techniques (depending, of course, on the model). We find them particularly attractive for getting started with simple models and integrating them into software stacks. Since there weren't any industrial-grade DD solvers, we built one. And we started nextmv to give companies the modeling, optimization, and simulation tools we wish we'd had. Our tools are for software developers with deadlines. They let you flexibly model nearly any business rules, easily integrate models into software stacks, and test them so you know they're behaving as you expect. What can you do with them? Dynamically route buses based on passenger requests. Minimize shipping cost for packages. Schedule workers based on demand forecasts. Hop (our optimizer) lets you model decision problems as state machines. Dash (our simulator) is also state-based, so you can optimize and simulate using the same code. We've prioritized making things developer-friendly. You can write and test models like any other software. Larger, more complex models can be composed out of smaller, simpler ones. Optimization and simulation models are built from Go source into simple binary artifacts. (We think of this as Docker for decision science.) They come with pre-built runners that make going from development to testing in CI to production deployment trivial. They have JSON I/O for easy integration, and run in a CLI, over HTTP, or in Lambda. Not all operational decisions need complex optimization, but they all benefit from simple automation and integration, fast iteration cycles, and continual visibility. We give you this from the beginning, then let you layer in fancier optimization stuff if you need it later. Here's a screen cast showing a simple routing model in Lambda: https://ift.tt/3dfLtv2 . We've seen developers without optimization backgrounds create models to minimize delivery time and deploy them to Lambda in less than 24 hours. We're eager to hear about your experiences in this area and/or ideas on faster ways to get automation into production. We would love any and all feedback that this community can offer, so don't hold back! March 19, 2020 at 10:50PM

Show HN: Remotework.com – not JUST another remote jobs site https://ift.tt/2U1IcYt

Show HN: Remotework.com – not JUST another remote jobs site Hello Hacker News! This is James from RemoteWork.com (https://remotework.com/) I am building a marketplace for the remote worker community, and to connect remote jobs to remote workers. I hope for this not to become just another jobs board. I am much more interested in helping remote workers solve for loneliness and build community, shift skilled work away from the coastal cities and other "soft" benefits of remote work. Like many other readers here on Hacker News I am following the Shelter-in-Place order in the bay area due to COVID-19. I have been sitting on RemoteWork.com as a concept since before 2017. I was originally inspired by Greg Caplan and his Remote Year (RemoteYear.com) project, I looked up LeapYear.com and stumbled upon Venture.com, they happened to have RemoteWork.com available & I have always had it on my shortlist of domains to use for a future concept. Then around NYE of 2020, as everyone was making predictions about what the next decade held, a consistent theme was that a shift towards remote work would become one of the big shifts of the 2020s. Who could have guessed it would happen so fast? I secured a lease with Venture.com shortly after Jan 1st. I setup a no-code MVP using Sharetribe Go. I have been working remotely or part of a remote team for the past 5 years & am familiar with the challenges it presents to the individual and to the organization. Personally, I really wanted to solve for the community and educational side of people beginning to work remotely. Working remotely may not be for everyone, but I think it could be a benefit for most people who are able to perform their jobs without being in an office, if given the right tools and guidelines outlining best practices. This is just the beginning. I hope we can start a movement that benefits both workers and employers. A movement that can reduce traffic congestion and improve overall job satisfaction thru work/life balance. Join us. Join the movement. Join RemoteWork.com March 19, 2020 at 02:55AM

Launch HN: Fly.io (YC W20) – Deploy app servers close to your users https://ift.tt/33rnswx

Launch HN: Fly.io (YC W20) – Deploy app servers close to your users Hello Hacker News! We're Kurt, Jerome, and Michael from fly.io ( https://fly.io/ ). We're building a platform to run Docker applications close to end users. It's kind of like a content delivery network, but for backend servers. I helped build Ars Technica and spent the majority of my time trying to make the site fast. We used a content delivery network to cache static content close to anonymous readers and it worked very well for them. But the most valuable readers were not these, but the ones who paid for subscriptions. They wanted personalized content and features for interacting with the community – and we couldn't make those fast. Content delivery networks don't work for Ars Technica's best customers. Running Docker apps close to users helps get past the "slow" speed of light. Most interactions with an app server seem slow because of latency between the hardware it's running on (frequently in Virginia) and the end user (frequently not in Virginia). Moving server apps close to users is a simple way to decrease latency, sometimes by 80% or more. fly.io is really a way to run Docker images on servers in different cities and a global router to connect users to the nearest avaible instance. We convert your Docker image into a root filesystem, boot tiny VMs using a project called Firecracker (recently discussed here: https://ift.tt/32XLUFu ) and then proxy connections to it. As your app gets more traffic, we add VMs in the most popular locations. We wrote a Rust based router to distribute incoming connections from end users. The router terminates TLS when necessary (some customers handle their own TLS) and then hands the connection off to the best available Firecracker VM, which is frequently in a different city. Networking took us a lot of time to get right. Applications get dedicated IP addresses from an Anycast block. Anycast is an internet routing feature that lets us "announce" from multiple datacenters, and then core routers pick the destination with the shortest route (mostly). We run a mesh Wireguard network for backhaul, so in flight data is encrypted all the way into a user application. This is the same kind of network infrastructure the good content delivery networks use. We got a handful of enterprise companies to pay for this, and spent almost a year making it simple to use — it takes 3 commands to deploy a Docker image and have it running in 17 cities: https://ift.tt/2wlngCT . We also built "Turboku" to speed up Heroku apps. Pick a Heroku app and we deploy the slug on our infrastructure .. typical Heroku apps are 800ms faster on fly.io: https://fly.io/turboku/ We've also built some features based on Hacker News comments. When people launch container hosting on Hacker News, there's almost always a comment asking for: 1. gRPC support: apps deployed to fly.io can accept any kind of TCP connection. We kept seeing people say "hey I want to run gRPC servers on this shiney container runtime". So you can! You can specify if you want us to do TLS or HTTP for an app, or just do everything yourself. 2. Max monthly spend: unexpected traffic spikes happen, and the thought of spending an unbounded amount of money in a month is really uncomfortable. You can configure fly.io apps with a max monthly budget, we'll suspend them when they hit that budget, and then re-enable them at the beginning of the next month. One of the best parts of building this has been seeing the problems that developers are trying to solve, often problems we didn't know about beforehand. My favorite is a project to re-encode MP3s at variable speeds for specific users (apparently the Apple Audiobook player has no option for playback speed). Another is "TensorFlow at the edge" — they trained a TensorFlow model to detect bots and run predictions before handling requests. We're really happy we get to show this to you all, thank you for reading about it! Please let us know your thoughts and questions in the comments. March 18, 2020 at 06:15PM

Show HN: Across – Supercharge your customer experience in Slack https://ift.tt/2WgXbPW

Show HN: Across – Supercharge your customer experience in Slack Hi HN! We're Parthi and Kunal from Across (https://acrossapp.com). Across allows you to scale high touch experience you provide your customers when you create shared Slack channels with them. With Across, you can track customer requests, automate responses and message customers across Slack channels. We've built and shipped 7 products recently and we always create shared Slack channels with our customers. This is great for creating a tight feedback loop between us, and making sure we're extremely responsive to customer requests. The problem is that this experience doesn't scale. When you have 20+ Slack channels with customers, it becomes impossible to remember who to follow up with, who on your team is responsible for which customer request, etc. And there aren't great integrations between Slack and existing task management and bug tracking tools today (most just allow you to create a ticket). So we hacked together a solution for ourselves. With Across, we've built a ticketing and task management system on top of Slack, so you can keep your team organized and on top of all customer requests. You can reply directly from a ticket and we'll automatically post the response to the right channel, customer, and thread, so you never lose track of a conversation again. This is just the start! We're looking into building a whole suite of tools and integrations on top of Slack to make customer engagement better. Looking forward to hearing what you'd want us to build next. Thanks for checking us out! March 17, 2020 at 12:20AM

Show HN: Fighting Harmful Coronavirus Disinformation Hi everyone In times like these it's important to watch out for each other. A great part of that is having access to the right information that can be crucial for everyone's well being. I'm sure many of you have heard about people advising others through viral social media posts about dubious treatments, involving anything from garlic water to Alex Jones selling a toothpaste that is supposed to cure you. This is all incredibly irresponsible and dangerous for the world community. I woke up in the middle of the night thinking about this, and decided to put together a Google spreadsheet, which allows anyone to list products, the claims associated with various products and references to such claims. This way, no one is chosen as the arbitrator of truth, but rather has the ability to back up claims with a reference that either supports or refutes the claim. You can find the spreadsheet here: https://ift.tt/3d0Fhqp Right now anybody can edit the spreadsheet. If it becomes gets popular, I will probably have to limit interaction to comments, in order to mitigate spam. Stay safe out there, Fredrik March 16, 2020 at 02:20AM

Launch HN: Synapsica (YC W20) -AI enabled global radiology reporting marketplace https://ift.tt/33pih08

Launch HN: Synapsica (YC W20) -AI enabled global radiology reporting marketplace Hi I am Dr Cherian. Synapsica (www.synapsica.com) is a global marketplace for radiology reporting, made better with AI automation. Margin pressures on radiology practices are increasing due to reimbursement cuts and acute shortage of skilled manpower. Reporting fee constitutes ~75% of their cost structure. These practices find it difficult to improve the cost efficiencies while maintaining reporting quality as they are limited by speed & accuracy of human radiologists (quality-efficiency trade-off) & volume fluctuations. Synapsica is an AI-enabled marketplace for radiology reporting. We onboard such radiology practices on our cloud-based SaaS and improve their speed & quality of reporting even while reducing skilled manpower requirement & cost. We can do this without hurting the quality because of our proprietary algorithms & business model which include: - Machine learning based non-clinical workflow automation - Automated image interpretation & report preparation using deep learning - Access to a flexible pool of client radiologists to absorb case volume fluctuations We have completely automated the X-Ray Spine (DMX) reporting. Currently, we are running a $100k pilot with one radiology practice at 250 chiropractic clinics in the US. This deal has a potential of $1mn ARR at 80% margin with 3000 clinics in the US. We have partially automated MRI Spine. MRI constitutes 40% case volume and majority revenue for over 7000 outpatient diagnostic setups in the US. Currently in negotiations with a radiology practice present across 4 states in the US with over 80k scans per annum. We have a unique business model that embeds a virtuous loop of proprietary data. Cross-enterprise workflow and radiology reporting data allow for the creation of new automation that increases the value proposition of the platform over time. Would love to receive your views, critical suggestions and feedback! If anyone in your family or around who has undergone a radiology investigation, would love to hear experiences. Specifically about how long it took for the report and did it in anyway affect the overall treatment you required. Any connects to Radiology practices who can benefit from Synapsica is most welcome! Thanks March 14, 2020 at 03:01PM

Launch HN: Ophelia (YC W20) – At-home recovery for opioid addiction https://ift.tt/2w3bs80

Launch HN: Ophelia (YC W20) – At-home recovery for opioid addiction Hi HN, My name is Zack, and I'm the founder of Ophelia. We help people quit opioids without going to rehab. We offer online doctor's visits, medication for withdrawal and cravings, and long-term support for recovery. There’s a treatment for opioid addiction that works, and it’s low-cost, discreet, and convenient. It’s called medication-assisted treatment (or MAT), it reduces mortality by more than 5x [1], and it resembles treatment for anxiety or depression: medication and therapy. Yet 80% of the 3 million Americans addicted to opioids are not getting it. You can read more about MAT at [2] [3] [4]. I decided to work on this problem after my girlfriend died of an overdose last year. She wanted to quit, but she was afraid of losing her job and her privacy, and she found it easier to get this medication from a drug dealer than a doctor or rehab. The rest of the story is too sad to articulate, and I don’t want this post to be about her. It’s about all of the people just like her, struggling to get help today. This is why I started Ophelia: to lower the barriers to proven, lifesaving treatment. Most Americans struggling with opioids have jobs, families, and privacy concerns that make rehab an impossible option. They want to quit , but they’re afraid of withdrawal, and the medication that helps is too hard to get: doctors need a special waiver to prescribe it, which only 5% of them have [5], so most people are buying it on the black market. Yet, drug dealers aren’t doctors, and the statistics support it: every 11 minutes, another American dies of an opioid overdose – now the #1 cause of death for Americans under 50. As it turns out, rehab is not just unnecessary: the data shows it rarely works anyway [6] [7]. Without medication, 90% of people relapse in the first 3 months: yet, 2/3rds of rehabs don’t offer medication, and most don’t even employ doctors! Thus: 80% of people avoid getting help, and the rest succumb to pseudoscience that does nothing to address their problem. Ophelia’s mission is to replace drug dealers with doctors, without any loss of privacy or convenience. We make MAT discreet, convenient, and affordable for anyone who needs help but can’t or won’t go to rehab. Our medical directors are two of the best addiction specialists in the world (Dr. Adam Bisaga and Dr. Arthur Robin Williams, both Columbia Professors and NIH-funded research scientists), and we’re now treating patients in Philadelphia and New York, through a combined in-person and telemedicine approach. There's a problem, though: we're restricted by regulations from letting people know that this treatment is available. Both Facebook and Google require a third-party certification before allowing us to use their platforms, and many sites like Reddit don't allow any advertising for addiction treatment at all. We would love your help figuring out how to get past this bottleneck. The other big problem is the stigma around addiction, which stops most people from sharing success stories about MAT, so its efficacy is underappreciated. If you know anyone who is personally struggling with this issue, please make sure they know about MAT. It can literally save their life. If you have thoughts about how we can solve these problems, I would be grateful for your help: any ideas to increase awareness of MAT or just personal stories that can help us better understand the needs of our patients. Thank you, HN. Your time and support mean a lot. Zack Gray, Ophelia Founder & CEO P.S.

Launch HN: Castodia (YC W20) – Populate Google Sheets from databases https://ift.tt/2U0FKAk

Launch HN: Castodia (YC W20) – Populate Google Sheets from databases Hey HN, we’re Jimmy and Ayazhan, founders of Castodia (https://ift.tt/3d1Dr95). We help pull data from databases directly into Google Sheets. It’s basically a live database connector for Google Sheets that allows for data refreshes. Before we started working on this, we were working on an idea around data pipelines. It didn’t take off so we had to pivot mid-batch. We had less than 1 month to do user interviews, build our product, get it approved, and launch it. To start with, we knew we wanted to stay in the data space. We spent the first week talking to over 30 people at different companies. In those conversations, we noticed that sales, marketing, and operations teams constantly need to ask developers to help them export data from the database and often have to submit follow-on data requests because they forgot to add a dimension needed for analysis (they often do this by submitting Jira tickets). This is an inefficient yet surprisingly common thing at companies today. Perhaps even more surprising is that data scientists at big companies like Facebook, who have invested heavily in data infrastructure and analytics tools, often use spreadsheets as a step in their data analysis workflow. While they can pull data for analysis themselves, they too export data into CSV and then open it in a spreadsheet. This means that their data doesn’t update automatically and the process has to be repeated each time. At first, we were considering building our own BI tool to solve this problem. However, during our conversations we noticed that people feel new-tool fatigue, especially when their companies rotate through different tools that are used for the same purpose. For instance, we’ve heard of companies going from Tableau to Looker and back to Tableau. Or from Kibana to Sisense to Looker. Sometimes it feels like companies are paying a lot of money for tools that people aren’t really using just because it’s the thing everybody “needs to have”. Each one comes with its own structure, data modeling and steep learning curve. It's overwhelming. At some point people just realize that whatever tool they learn will likely change once a new VP gets hired and wants to do things in a new way. In anticipation of that, they default to the one tool they know how to use and likely won’t be replaced soon. Spreadsheets also happen to be an elegant solution for simple calculations, quick pivots, and high level data exploration. They are elegant in a way that no $50k a year enterprise visualization tool can be - not because they can’t do those things, but because people don’t know how to do it quickly with them. It’s also hard to change workflows for people who live in spreadsheets. Spreadsheets are a pretty good for ad-hoc analysis and summaries that are used for presentations and reports. So instead of another BI tool, we built a Google Sheets add-on that connects to a database and lets them search through tables, filter/order the data, and then load it into Sheets directly. In the future, we’ll let them schedule data refreshes for any saved query, so all their calculations and pivot tables update with the latest data from the database. We’ve built our first integration with Postgres and testing a MySQL, MongoDB, and public dataset connector. We plan to add integrations to more data sources, including data warehouses such as Snowflake and BigQuery. We implemented it to only get read-access to the database and we don’t store connection credentials or replicate data in our database. We are focused on data analysis at the moment, but a few customers have requested features to also write into database (write access to the database). Not sure yet how to do this safely with spreadsheets or whether we should at all. We’ve heard suggestions such as database write roll-backs or some intermediate data queue that can be approved by table owners. Other challenges include: (1) building data connectors because many data sources spits out data differently, which means we have to parse it differently to make it accessible from a uniform interface. (2) We make connections to databases and perform all queries using AWS lambda functions (thank you serverless!) Some queries are taking minutes to execute, but AWS drops connection after 29 seconds. (3) It is hard and, as HN often points out, risky to build a product that depends on Google. We're also running into Google Sheets' row limitations - still figuring out a way to work around this for large databases. We’ve been bouncing ideas around building a back-end to perform heavy computations while only displaying a sampled subset of data in the spreadsheet. We think it's worth it to plunge ahead despite all these issues, though, because having a spreadsheet interface to their data is very much what our users want. We plan to charge users a monthly fee for use of our product and we'll have a HN discount on our basic plan. We’d love to hear about your data analysis workflows, the tools you use to do this, any problems you’ve had getting data for analysis, and of course, your thoughts and experiences on this use of spreadsheets! Questions and specific integration requests are also welcome, and if you would like to be beta users, feel free to email us at founders@castodia.com. March 13, 2020 at 06:36PM

Show HN: I am creating a campaign to mitigate Covid-19 crisis in Spain https://ift.tt/3cMKx0O

Show HN: I am creating a campaign to mitigate Covid-19 crisis in Spain I have been thinking a lot why there is such a huge difference between mortality in Germany and Italy and I may have figured it out. This understanding could be possibly applied in Spain to avoid or at least mitigate similar level crisis that is currently taking place in Italy. I created a GitHub Pages based website https://ift.tt/2vhbjxz for the campaign. My main motivation for this choice is to promote transparency and collaboration. The GitHub page is located here https://ift.tt/33eJnqL The main takeaway is that the main difference is most likely in the family structure - many Italians live together with their extended family while Germans do not (or they have by some other means that I am not aware of kept their elderly not infected by the corona virus). If you think that this thinking is plausible then please support this campaign by either contributing or by sharing. It is especially important to reach Spanish people. I do not know any unfortunately at the moment yet. The time is running out fast. There are only few days left to act. Lets push this together and save Spain! March 12, 2020 at 11:22PM

Launch HN: Visual One (YC W20) – Event recognition for security cameras https://ift.tt/2Qb0STi

Launch HN: Visual One (YC W20) – Event recognition for security cameras Hi HN. My name is Mohammad Rafiee and I am the founder/CEO of Visual One ( https://ift.tt/2Q4Uayj ) We are building software for security cameras enabling them to recognize specific events. People use security cameras (aka IP cams) for various purposes—to monitor their properties, their kids, their pets, for elderly care, as doorbells, etc. But a shortcoming these cameras have is they rely mainly on motion detection to alert users and that leads to too many false alarms. What led me to work on this problem initially was my personal experience with the IP cameras which I used to watch my dog and also as a doorbell at my house which I rented out on Airbnb sometimes. After trying some of these cameras (Ring, Nest and Wyze), I realized motion alerts are pretty much useless and person detection that some like Nest offer is not broadly useful. For example, for my dog, I only cared to know if/when the dog walker picked her up or if she was doing something bad, like getting into my clothes, chewing my shoes/TV remote, getting on the bed, etc. The motion alerts were completely useless as she is moving all the time obviously--person detection was also not useful for any of these events. For my Airbnb rental use case (doorbell/outdoor cams), the main things I cared to know about were if the guests parked their cars in the wrong location which pissed off my neighbors, or if the garage door was left open, or if there were a lot more people staying at the house than allowed. Again, motion alerts or person detection were not useful at all. Having a background in machine learning & computer vision, I felt this is a problem that is just starting to become solvable thanks to the powerful deep learning techniques developed in the the last 3-4 years. Over the last 6 months, we have been building a cloud-based solution addressing this shortcoming for any IP camera without any dependency on the hardware. Our software allows users to create custom alerts for things that matter to them, like their dog chewing on shoes, their kid playing with the stove or their packages being stolen by porch pirates. It also allows them to search for past events after the fact instantly. Currently, we support four categories of events: - A specific object appeared / disappeared, e.g. dog appeared, bicycle disappeared, package disappeared (coming soon.) - A specific object in a specific location, e.g. a car parked in front of the driveway, elderly person taking medications, dog in the (neighbor’s) lawn, person getting into the garage. - Two objects interacting, e.g. dog getting on the couch, kid playing with the stove, dog chewing on a shoe. - Facial recognition based events, e.g. new person detected, a specific person appeared, max occupancy violated. Users can create a new event in any of the above categories by providing a few simple inputs, e.g. pick the objects involved and the interaction between them, or specify a zone. Once the event is created, our software can immediately recognize that event with good accuracy. The users can also give a thumbs up/down when they get an alert and their feedback is incorporated back into the models to improve their accuracy over time. Users can adjust the sensitivity for each event (precision and recall trade-off) based on their use case. In addition to the smart alerts described above, we also index the footage in real time to allow users to query for past events after the fact and get the results instantly instead of having to go through all the past footage to find something they care about. For example: users can query the clips of when a laptop disappeared or a truck appeared. Our solution can also alleviate privacy concerns since we only store short video clips on the cloud for alerts corresponding to user’s events of interest instead of for every motion detected. We currently support Nest Cams and also offer our own cameras (same as the cameras sold by Wyze) with indoor and outdoor options. I would love to hear any feedback/thoughts you have. We are exploring different niche use cases to focus on initially and would appreciate any thoughts you may have based on your personal experience or any insights you may have. Feel free to comment here or shoot me an email at rafiee@visualone.tech March 12, 2020 at 10:11PM

Launch HN: Terusama (YC W20) – We help warehouses schedule trucks https://ift.tt/2wRqNbL

Launch HN: Terusama (YC W20) – We help warehouses schedule trucks Hi HN, Andrew and Chris here. We’re building Terusama ( https://ift.tt/33cwxt6 ), a truck appointment system for logistics teams at warehouses and distribution centers. We automate the labor-intensive process of coordinating arrival times with a trucking company, checking a truck in at a facility, and keeping track of everything. Oh, and we have a theme song: https://www.youtube.com/watch?v=fyp4O4s5tk4 The status quo here is really antiquated software that is really hard to use. Not only is the current way of doing things inefficient for logistics folks, it has a big impact. The inefficiency created by poor supply-chain coordination costs $30B a year in the U.S. and generates billions of tons of C02, mostly from trucks idling in parking lots. On top of that, it has a huge impact on the lives of truck drivers, who are legally limited to 11 hours of driving time each day. Waiting at warehouses often eats up 3-4 of those. Those wasted hours really add up, making the job unsustainable for many and contributing to another problem in the industry - driver turnover, which is over 90%. Most of this inefficiency is caused by the high level of friction in communication between the people who manage trucks, the drivers, and the people who the drivers are delivering to. The freight industry has made a ton of progress with software to help manage their fleets, but warehouse logistics software hasn’t caught up. Chris and I were students together at Indiana University. We became really interested in this space at our later jobs. I was working at Uber Freight (formerly Otto), and Chris was consulting for companies in the industry. We were constantly amazed at how big and complex an issue it was, and surprised that nobody was thinking about it in the same way we were. We started talking to as many people in the industry as possbile to figure a better way to manage logistics. The result was the version of Terusama we launched with in the beginning of the year. We have been since iterating on the product with a core group of customers. We streamline or automate most of the repetitive and administrative processes needed to keep trucks flowing smoothly in and out of a facility. We provide dispatchers at trucking companies and brokerages a way to search through facilities, and schedule directly with these facilities. When a truck driver arrives at a warehouse, we check them in at a kiosk. Our customers get a dashboard where they can track and manage loads coming to their facility. Logistics teams get visibility into their incoming trucks, the ability to communicate with drivers and carriers, and to track a load through its lifecycle (from staging through completion). Everyone involved is kept in the loop with smart notifications. In the future, an API will make it easy for anyone with a brokerage or trucking company to get facility availability (to feed into truck routing optimization), and schedule appointments. We’ll also offer services to help carriers reduce the risk of missing truck appointments. One of the most important things we’ve learned in this time is how important reliability is for a mission-critical app. It's obvious in retrospect, but it definitely changes your approach when building an application - requiring heavier testing, redundancy, and support as a form of redundancy. These days you hear a lot about things like autonomy and AI in the freight industry. We believe that to get the value promised by these things, we first have to upgrade the outdated technology infrastructure that currently runs the industry. Our goal is to build that infrastructure, while solving today’s pressing problems. We’re excited to see what HN thinks of our platform. We’re eager to hear about HN users’ experiences, ideas, and know there is a ton of expertise among the community to learn from. And if you’re in the industry, we’d love to hear about your experiences with truck scheduling! March 12, 2020 at 01:01AM

Launch HN: DeepSource (YC W20) – Find and fix issues during code reviews https://ift.tt/2IQnnJr

Launch HN: DeepSource (YC W20) – Find and fix issues during code reviews Hi HN! We're Jai and Sanket — founders of DeepSource ( https://deepsource.io ). We’re automating objective parts of code review using static analysis to ensure the code is free of common issues (anti-patterns, bug risks, performance bottlenecks, and security flaws) before a reviewer looks at it. This prevents the reviewer from having to manually point out objective issues and ensures they don’t make it to production. After college, Sanket co-founded DoSelect where I joined as the first engineer. Both of us have been contributing to open-source projects for a few years then. In the beginning, we didn’t have any processes setup around code reviews. We had some IDE plugins to run the linters, and some team members used them as pre-commit hooks. We didn’t have any tests back then and used to spend too much time on some pull requests pointing out improvements and if the pull request was very large, we never reviewed it — direct merge. Then the engineering team started to grow, multiple folks started contributing to the same repositories and pull requests were often stuck for 5-7 days without any activity. To make sure the new commits are free of the common issues, we added multiple static analysis tools as part of our CI jobs. This became a pain sooner than expected as they were throwing hundreds of lines of logs in the CI and we had to fight through duplicate issues. Critical issues were hidden amongst other minor issues and false-positives, and often missed. Once a while, we tweaked the linter config files with the issues that didn’t make sense to us — to reduce noise in the CI logs. It didn’t work out after a while and we invested in a couple of commercial code quality tools but ended up disabling them as well. Their issues weren’t categorized or prioritized, analyzers were never updated with new rules, didn’t have any way to report false-positives. We came across a paper — Lessons from building static analysis at Google [1]. It is a beautiful paper with the following insights: 1) Static analysis authors should focus on the developer and listen to their feedback 2) Careful developer workflow integration is key for static analysis tool adoption 3) Static analysis tools can scale by crowdsourcing analysis development. We started building DeepSource in December 2018. The initial release supported Python and integrated with GitHub. Our approach was to first curate all the issues available from open-source static analysis tools, de-duplicate them, add better descriptions with external reference links — so you just add python analyzer to the `.deepsource.toml` file with some metadata (version, test patterns, exclude patterns,.) and analysis will run on every commit and pull request. To cut down the noise, we only show you newly introduced issues in the pull-request by default, based on the changeset — and not all the issues present in the changed files. We also provide a way for you to report false-positive issues directly from the dashboard. If the report is valid, we update the analyzers to resolve it within 48 - 72 hours. After this release, we started writing our own rules by walking through the Abstract Syntax Tree to find patterns. So far, we’ve 520+ types of issues in the Python analyzer. Some of the custom issues we added recently are: File opened without the `with` statement, using `yield` in comprehension instead of a generator expression, use items() to iterate over a dictionary. A few months back, we released the Go analyzer and also added support for GitLab. We’re working on supporting Ruby and JavaScript and integrations for Bitbucket and Azure DevOps. The analyzers are not limited to programming languages, and we added one for Dockerfile and Terraform as well. DeepSource is free to use for open-source repositories and we make money from private repositories based on a per developer per month/year subscription. Lately, we realized some of the issues were occurring in tens of files. Though DeepSource reports them, one had to manually fix all the occurrences. We just released autofix support in Python for 15 most commonly occurring issues to start with. Autofix uses Concrete Syntax Tree to visit the issue location and make modifications in the code for which the issue is raised, and then generate a patch for that modification. When an autofix is available for an issue, you can view the suggested patch and on approval, a pull request will be created with the fixes. We're working on improving the coverage of issues we can autofix across the analyzers we support. Give us a try: https://deepsource.io/ Here is the documentation: https://ift.tt/33erJTN We would love to hear your experience using these tools and feedback/suggestions on how can we improve! Please let us know in the comments. We’re also at founders [at] deepsource.io. [1] https://ift.tt/39GxU5u March 11, 2020 at 08:38PM

Launch HN: Cotter (YC W20) – Secure One-Click Phone Number Login https://ift.tt/337agMX

Launch HN: Cotter (YC W20) – Secure One-Click Phone Number Login Hi, HN! We are Putri, Anthony, Kevin, Michelle, and Albert from Cotter ( https://www.cotter.app ) Cotter is an authentication SDK that lets users log in to your website/app securely using phone numbers, without a password. We built Cotter because authentication that works in the US doesn’t work in Southeast Asia, India, LatAm, and Africa. People there prefer to use phone numbers to log in because they don’t use email and good passwords are hard to remember. We come from Indonesia. Over there, in order to reach more people, mobile apps make their login easily accessible to everyone, which has resulted in the removal of emails and passwords. They made SMS based authentication a standard across sign up, login, and transactions. However, SMS-based authentication comes with a security tradeoff and costs both users and businesses millions of dollars. Scammers have figured out several ways to extract verification codes via social engineering, SMS forwarding, and SIM-swapping. One of us has lost money due to SIM swapping and we've seen family relatives lose their digital wallet balances from social engineering. It’s easy for these scammers to extract the verification code from their target. The victims of this misconduct tend to be ride-hailers, online merchants, and other people whose income depends on mobile apps, so this issue can hit hard. To address this, we've built a secure authentication SDK that has the convenience of only using a phone number but does not have those security drawbacks. Cotter is unique in 3 ways. First, integrating with Cotter is very fast and easy - developers can provide a full-suite authentication including login, SMS one-time password, Trusted Device, Biometric, and PIN in just a few lines of code. Second, Cotter works across apps/websites, just like Google Sign-In. Once the user’s phone number is verified in one app, the user doesn’t need to re-verify their phone number again in other apps - one user does not have to be verified over and over again. Third, Cotter is secure. It works like Apple’s Trusted Devices where users can only log in from a Trusted Device. It also works from within your app (no third-party authenticator app). We are following the FIDO protocol for this. Cotter’s SDK generates asymmetric keys in your device, saves the private key in secure storage, and sends the public key to Cotter's server. Apps can choose to secure the keys using Biometric/PIN. Every time the app requests an authentication, either for a login or for a transaction, Cotter’s SDK will send a signature using the private key that the app’s server can verify. How does Cotter make money? We charge $0.02/API call + Standard SMS Rates. We would love to hear more about your experiences authenticating users! What are your biggest pain points and what services do you wish existed to solve those? We are also happy to discuss how we can make Cotter better and more secure. Either comment here, or shoot us an email anytime at team@cotter.app. Also, if you want to know more about integrating with us, you can check out our documentation at https://docs.cotter.app March 10, 2020 at 11:15PM

Show HN: Engineering group to help medical staff against Covid-19 https://ift.tt/2TTnYyV

Show HN: Engineering group to help medical staff against Covid-19 We've created an engineering group to help in the event of a severe COVID-19 crisis. Right now we have engineers, PhDs, and the owner of a manufacturing company, with a supply chain and offices in New York, Florida, and Taiwan. The idea behind the group is that a COVID-19 outbreak might be something our medical system hasn't seen before. There may be shortages or special needs of medical equipment and other resources. We think we can help by building certain devices. We probably can't build ICUs, but we could provide real help to a burdened medical front-line in a crisis. We're doing this in a deliberate and pragmatic way, informed by medical opinion. Right now, we're looking for more help—anyone with project management, engineering as well as non-technical experience. We're especially looking for doctors, particularly those with emergency room, triage experience, or who have (are) dealing with the current outbreak. If you're interested, please get in touch. My email is in my profile. March 10, 2020 at 09:26PM
