Show HN: Find out what music fellow HN users are listening tohttps://news.ycombinator.com/item?id=26799967Hey lovely HN crowd,I am currently building a little tool which works on top of Spotify. It is called tastemaker.cc and offers different ways to discover new music.The most recent feature I build is called GroupFun™ (name is still work in progress) and allows to join a Spotify playlists which is automatically populated with the favorite tracks of all participants.Not sure if it is a good idea (no clue if the platform can handle the traffic), but I would like to start the following experiment: A huge HN playlists to see what the HN crowd is listening to :DYou can either join the playlist by entering the code "hn" as group name on https://tastemaker.cc/ or directly via following link: https://tastemaker.cc/api/join/groupfun?code=hnAfter log in to your Spotify you can allow the application and will be added to the playlists.Let's see how my little project can handle this :)p.S. Yes I know it requires quite some privileges on your Spotify to get your top tracks...sorry that is how it is at

Full video of Starship’s seven-minute high-altitude test flighthttps://spaceflightnow.com/2020/12/10/full-video-of-starships-seven-minute-high-altitude-test-flight/Video credit: Stephen Clark / Spaceflight Now This video replay shot from South Padre Island shows SpaceX’s Starship SN8 prototype rocket taking off from Boca Chica, Texas, climbing high into the atmosphere, then gliding back to a fiery crash landing after an otherwise successful test flight. The nearly seven-minute experimental flight Wednesday began with liftoff at 4:45 p.m. CST (5:45 p.m. EST; 2245 GMT) powered by three Raptor engines. The Raptor engines generated more than a million pounds of thrust at full throttle, guzzling a super-chilled mixture of methane and liquid oxygen. Designed for vertical takeoffs and vertical landings, the Starship is part of a giant new rocket SpaceX says will carry more than 100 tons of cargo into space per mission, and as many as 100 people on expeditions to Mars. The test flight targeted an altitude of 41,000 feet, or 12.5 kilometers, higher than most commercial airliners fly. One of the Raptor engines shut down a little more than a minute-and-a-ha

Ask HN: Healthy, cheap, easy meals to make, like this recipe?https://news.ycombinator.com/item?id=24748659The "ramen" in "ramen profitable" refers to instant ramen, which is just about the cheapest food available.Please do not take the term literally. Living on instant ramen would be very unhealthy. Rice and beans are a better source of food. Start by investing in a rice cooker, if you don't have one.Rice and Beans for 2n olive oil or butter n yellow onions other fresh vegetables; experiment 3n cloves garlic n 12-oz cans white, kidney, or black beans n cubes Knorr beef or vegetable bouillon n teaspoons freshly ground black pepper 3n teaspoons ground cumin n cups dry rice, preferably brown Put rice in rice cooker. Add water as specified on rice package. (Default: 2 cups water per cup of rice.) Turn on rice cooker and forget about it.Chop onions and other vegetables and fry in oil, over fairly low heat, till onions are glassy. Put in chopped garlic, pepper, cumin, and a little more fat, and stir. Keep heat low. Cook another 2 or 3 minutes, then add beans (don't drain the beans), and stir. Th

Ask HN: Bridging the gap between formal physics education and research?https://news.ycombinator.com/item?id=24379221I finished my undergraduate education in physics and computer science not too long ago, but have been working in FAANG ever since. My passion has always been physics but unfortunately to pay off loans/medical bills/etc I was more or less forced into software engineering.I took the standard undergrad physics 'core curriculum' in college (e.g. Griffiths quantum, e&m, K&K mechanics, etc). I've been keeping up with my studies since then by slowly working my way through various 'graduate texts', e.g. Sakurai's text on quantum mechanics and Kardar's on statistical physics of particles.I'd like to do some side work in an experimental quantum computing lab and have been in contact with various universities; however, what I'm finding is that there's a large gap between the material in the papers being read and written by the groups I've spoken with, and my formal education. The papers are constantly referencing ideas, equations, and experiments that went unreferenced in all the texts I've read

I found TD Ameritrade's API to be extremely poorly documented, so I fixed ithttps://news.ycombinator.com/item?id=22807605Hey guys, I was trying to figure out how start with TD Ameritrade's API to experiment with some algorithm trading, and found little to nothing. By piecing together a few YouTube videos and guides from reddit, I created a 12-page (yes, 12 pages worth of stuff to even get started with their API), step by step PDF guide and listed it on this website I just threw together: https://btbtrading.wordpress.comIts totally free on Gumroad: https://gum.co/XKxGc (pay what you want, minimum amount is $0), so if you have been looking to get started with algorithm trading with TD Ameritrade and hit a dead end, look no further. This guide is for you.Let me know what you think!

Ask HN: What's is the state of the art of lifelogging?https://news.ycombinator.com/item?id=21268588I want to log everything about my life.A wearable camera paired with advanced computer vision would go a long way, but I haven't found a practical solution yet.I already log the easy stuff:- Computer/phone usage (RescueTime, ActivityWatch, keylogger, TimeSnapper)- Location (Google Maps Timeline, GPS Logger)- Pictures (Google Photos)- Internet usage (Google History)- Fitness (Mi Fit, Google Fit, Strong)- Finance (Mint)I even experimented with 24/7 background audio recording but didn't have much success with Google Cloud Speech-to-Text.The biggest challenge for me is manual logging. Taking pictures of my environment can go a long way (food, receipt, barcode, injury, product, book, ad, ticket, activity, weighing scale) but it becomes more difficult when I need to retrieve and log information from memory (cash spending without a receipt, weightlifting workout, pain, mood, idea, question, todo). I don't like single-purpose apps designed to log a specific domain of events and would prefer so

Show HN: Tok'n'talk – Conversations using your ERC20/ERC71 tokenshttps://news.ycombinator.com/item?id=17957933Hi, we've created an app https://tokntalk.club/ to experiment with using tokens ERC20 and ERC721 in slightly different way than monetary use cases you're familiar with.ERC20 - They are treated as memberships in 'token clubs'. If you have given ERC20 token you can write messages in its dedicated club. eg. Maker MRK club https://tokntalk.club/clubs/MKR or in Berlin Coin BRLN club https://tokntalk.club/clubs/ethereum:0x80046305aaab08f6033b5...ERC721 - Those tokens can be used as avatars. To give you ability to change 'personalities', create their history and grow them as recognizable characters. We are supporting ~40 different kinds of ERC721s and we're always looking to integrate new ones.Now, you might be asking: Why?The reason is simple. We believe that this is the only way for blockchain community to go forward. Communication based on signed messages is crucial for progress but it's not enough. We need filters rooted in the very base of our beliefs. Filters that will help guard our at
