New best story on Hacker News: Show HN: Trading cards made with e-ink displays
Show HN: Trading cards made with e-ink displays
556 by jonahss | 191 comments on Hacker News.
I made a thing! In 2014, I was holding a stack of iPhones and thought to myself: "Hey, if I had each phone display a playing card, I could click a button and they'd shuffle themselves" I pared that idea all the way down to this: trading cards made of e-ink displays. Right now, each card costs me about $20 each, but with only a bit more scale, I think I can get that down to $10. In doing this project, I learned how to design electronics and circuit boards. I learned Rust and wrote my first driver, I upped my CAD skills, 3D printed, and did my first resin casting. I generated the images on the cards using stable-diffusion. HN always seems to appreciate new uses for e-ink. Thought I'd share :)

Author here. This site lets you put in a username and get the users with the most similar writing style to that user. It confirmed several users who I suspected were alts and after informally asking around has identified abandoned accounts of people I know from many years ago. I made this site mostly to show how easy this is and how it can erode online privacy. If some guy with a little bit of Python, and $8 to rent a decent dedicated server for a day can make this, imagine what a company with millions of dollars and a couple dozen PhD linguists could do. Here's Paul Graham: https://ift.tt/XLU0pyO Here are some frequent HN commenters: (EDIT: Removed due to privacy concerns)

Ask HN: Azure has run out of compute – anyone else affected?

Last week we at n8n ran into problems getting a new database from Azure. After contacting support, it turns out that we can’t add instances to our k8s cluster either. Azure has told they'll have more capacity in April 2023(!) — but we’ll have to stop accepting new users in ~35 days if we don't get any more. These problems seem only in the German region, but setting up in a new region would be complicated for us. We never thought our startup would be threatened by the unreliability of a company like Microsoft, or that they wouldn’t proactively inform us about this. Is anyone else experiencing these problems?

I had the concept in my head for some time and firstly just prototyped it using only HTML & CSS. Sent it to a few friends and they liked it so I made it into its own website and added few 'competitive' features like click counter and share button.

Sometimes it takes a book or a course (or explanation from a mentor) for a topic to finally click for you that you were struggling with for a long time. For me, it was Stanford's EE261 course that made Fourier Transform click for me. Here is the link: https://ift.tt/schnO0S Similarly for deep learning it was fast.ai courses. For programming it was How to Design Programs at www.htdp.org. Your topic of choice may be anything, not necessarily CS.

Show HN: I built my own PM tool after trying Trello, Asana, ClickUp, etc.
505 by tonypham | 354 comments on Hacker News.
Hey HN, Over the past two years, I've been building Upbase, an all-in-one PM tool. I've tried so many project management tools over the years (Trello, Asana, ClickUp, Teamwork, Wrike, Monday, etc.) but they've all fallen short. Most of them are overly complicated and painful to use. Some others, like Trello, are too limited for my needs. Most importantly, most of these tools tend to be focused on team collaboration and completely ignore personal productivity. They are useful for organizing my work, but not great at helping me stay focused to get things done. That's why I decided to build Upbase. I try to make it clean and simple, without all the bells and whistles. Apart from team collaboration, I added many personal productivity features, including Weekly/Daily planner, Time blocking, Pomodoro Timer, Daily Journal, etc. so I don't need another to-do list app. Now I can use Upbase to collaborate with my team AND manage your personal stuff at the same time, without all the bloat. If these resonate with you, then give Upbase a try. It has a Free Forever plan though. Let me know if you have any feedback or questions!

New best story on Hacker News: Monumental (if correct) advance in number theory posted to ArXiv by Yitang Zhang
Monumental (if correct) advance in number theory posted to ArXiv by Yitang Zhang
789 by gavagai691 | 231 comments on Hacker News.
Yitang Zhang, the mathematician behind the 2013 breakthrough on bounded gaps in primes, posted to the arxiv today a result which (if correct) comes close to proving the nonexistence of Landau--Siegel zeros: https://ift.tt/q9fukT6 . To give a sense of the scale of this claim: If correct, Zhang's work is the most significant progress towards the Generalized Riemann Hypothesis in a century. Moreover, I think this result would not only be a more significant advance than Zhang's previous breakthrough, but also constitute a larger leap for number theory than Wiles' 1994 proof of Fermat's Last Theorem (which was, in my opinion, the greatest single achievement by an individual mathematician in the 20th century). Some discussion / explanation of Siegel zeros and Zhang's claim can be found here: https://ift.tt/S4IMOKP... https://ift.tt/wjYLcsS... An account of Zhang's remarkable story (and his previous breakthrough) can be found here. Famously, prior to his breakthrough, he worked at Subway and lived in his car: https://ift.tt/YK42o3P

Ask HN: Comment here about whatever you're passionate about at the moment

Hello stranger. It has occurred to me that one of the crucial elements of the early internet was the feeling that there was somebody out there, _somewhere_ on the globe, that was actually responding to that particular thing you were putting out there. It was a special feeling, because it was a sense of connection. Just being online and being part of the few select communities that existed back then was a commitment, and I believe that's in part what made it feel special. With all the world gaining access to the internet, I think we've gained a lot, but lost this sense of wonder: Since online interactions have now become commonplace to the point of para-social meaninglessness, any single post or message doesn't really feel all that _real_. HN is still the closest thing I know to that primordial kind of internet, and so I'm putting this post out there. It might get buried instantly, or it might survive, and on the off chance that it does: I encourage you to comment here about whatever you're passionate about at the moment, however niche it might be. It might let you find some likeminded people and maybe recapture a bit of the best aspects of the internet in those early days. In any case, I sincerely wish you a great day, from one surprisingly-real-but-currently-text-based being to another :)

Tell HN: A hacker's life is in danger, your awareness may be life saving
658 by michaeltimo | 64 comments on Hacker News.
It's been a month that Jadi (real name: Amir Emad Mirmirani), an Iranian geek, has been imprisoned in Iran's most notorious prison called Evin in Tehran. In Iran, he is one of the most famous people active in the field of programming and computer education. In his personal blog[0], he has been writing about technology and society for years. He has also a YouTube channel[1][2] to teach and encourage Iranians to programming and Linux, and a podcast[3] that has been explaining technology and science news along with his comments for several years. All this in a country with a dictatorial government where standing in the right place has a heavy price. His arrest occurred on October 5, a few days after the recent nationwide protests[4] began in Iran. Arrest at home with beating. The reason for this is not yet clear, but it is probably due to his efforts to increase awareness of the society about Iran's internet censorship system, and his positions against a company called ArvanCloud. Many claim this company help the government of Iran in implementing the internet censorship's system (something like Great Firewall of China). In Jadi's own words, this company has made it possible for the government to turn the Internet into an intranet at any moment and block people's access to international services. Something that happens in every demonstration in Iran including right now. The reason I am writing here is to raise awareness about him, which may lead to his release. All this may be nothing more than a false hope, but it is what I can do. From the news he covered in his podcast, it could be guessed that he is one of the regular readers of Hacker News. Perhaps hearing your support here will boost his morale behind bars in Evin. The prison which is also known as Evin University due to the number of educated political prisoners [5].
