Show HN: Turn any WiFi into a persistent group chat Try it out on your WiFi: https://tapchat.com I’ve always been shocked at the fact that it’s easier to chat with someone on the other side of the world than with someone who is on the exact same WiFi as you. I think that is a shame because WiFi networks are essentially a bunch of existing micro-communities which your phone already automatically connects to. Think about how many other people have used or will use the same WiFi as you at home, school, work, or in public; and so far it has been practically impossible to chat or share pictures with them. After leaving my job earlier this year, I decided to work on a simple chat app that solves this problem, by simply opening a persistent group chat for every WiFi you connect to, which allows for long-lasting conversations and meaningful relationships everywhere you go. So far a great use case I've seen are college campuses where thousands of students connect to the same WiFi, and who c...

Launch HN: Centaur Labs (YC W19) – Labeling Medical Images at Scale Hello HN! We are Erik, Zach, and Tom, the founders of Centaur Labs ( https://centaurlabs.io ). We’ve built a platform where doctors, other medical professionals, and med students label medical images, improving datasets for AI. The idea grew out of Erik’s research when he was a PhD student at MIT’s Center for Collective Intelligence. In short, he found that by aggregating the opinions of multiple people--even including some people with little or no medical expertise--they could reliably distinguish cancerous moles from benign ones better than individual dermatologists. The three of us have been friends since we were undergrads. When we would chat about Erik’s research, it seemed like a no-brainer that there’d be demand for more accurate diagnoses. We all had our frustrations that as patients, you usually have to trust one doctor’s opinion. So we built a mobile app called DiagnosUs where users around the world analyze m...

Launch HN: Trexo Robotics (YC W19) – Robotic Legs for Kids with Cerebral Palsy Hi HN community! We're Rahul and Manmeet, co-founders of Trexo Robotics ( http://bit.ly/2vuDyoN ) At Trexo Robotics, we're building wearable robotic devices to help children with disabilities learn to walk, in many cases for the first time in their lives. Video: https://youtu.be/3LW4LJIpa2o We are both Mechatronics undergrads from the University of Waterloo. Rahul later completed a Master's in Robotics at the University of Toronto and I've done my MBA at Rotman. We started this a few years ago when I (Manmeet) found out that my nephew, Praneit, has Cerebral Palsy, and that he would not be able to walk. Not walking can lead to contractures, hip subluxation, and many physiological and psychological issues for kids. We wanted to change that. We decided to use our robotics background, along with help from friends and the top rehabilitation researches in North America, and in 2016, watched my neph...

Show HN: Office Hours – Hold office hours by phone anytime, anywhere Hello HN! My name is Rohan Pavuluri, and I’m launching an iPhone app called Office Hours ( https://apple.co/2IK0usY... ). The app lets you hold “office hours” by phone anytime, anywhere. You can think of it as the green Facebook messenger symbol but for calls. In real time, easily let your network know that you’re free to accept calls. And easily find out who in your network is free to accept a call from you. I built Office Hours as a side project on the weekends with a friend to address the personal pain I feel scheduling phone calls. I run a nonprofit, and I love having conversations with everyone who reaches out to learn more about our work. But these conversations are generally painful to schedule for two reasons: 1. The back-and-forth email exchange to find a time slot is exhausting. 2. I don’t want to commit to time slots on my calendar because something that takes priority -- aka anything directly work-related ...

Show HN: High Schoolers start video series on how to write data structures in C Hi everyone! We (Christopher and Govind) have started a video tutorial series of 20-25 minute long episodes on how to make various common computer science data structures, such as vectors, linked lists, hashmaps, and so on. So far, we’ve done a two-part series on how to implement vectors. Links to parts one and two of the Vectors series: https://www.youtube.com/watch?v=vr0KzD_Owxc https://www.youtube.com/watch?v=t3kgbdhUIxU (Sorry about the low quality of the video in the first link, we accidentally recorded in 720p. The second part is in 1080p!) Although so far only one of us has done a video series on a data structure, we plan on taking turns to cover the most common data structures. Our endgame is to use all these data structures we build up to write a simple C compiler in a longer series of videos. We have some plans to use a partially scripted setup to streamline the explanations of core concepts, and ...

Show HN: PwnedPasswords as a (Micro)Service Recently I became interested in knowing whether the passwords I used were in the list of breached passwords. One way to find out is to send your password to the link here http://bit.ly/2vrGHam. However, while the owner of that website is a well respected security researcher, I still don't think it's wise to send my password to another website. So I downloaded the 24gb file, hashed my password and grepped the file for it. That unfortunately took a long time and I realized this was the perfect opportunity to use a BloomFilter and test the inclusion of a password in a set. With a bloomfilter, the 24gb file can be compressed down to ~2gb assuming a false positive rate of 1 in a million. You can achieve even better rates with lower false positives. Despite it dropping to 2gb, I wasn't satisfied and decided to compress the bloomfilter using golomb codes. This type of data structure is known as a golomb set and I was able to get the data...
