New best story on Hacker News: Ask HN: What are some cool but obscure data structures you know about?

Ask HN: What are some cool but obscure data structures you know about? 783 by Uptrenda | 371 comments on Hacker News. I'm very interested in what types of interesting data structures are out there HN. Totally your preference. I'll start: bloom filters. Lets you test if a value is definitely NOT in a list of pre-stored values (or POSSIBLY in a list - with adjustable probability that influences storage of the values.) Good use-case: routing. Say you have a list of 1 million IPs that are black listed. A trivial algorithm would be to compare every element of the set with a given IP. The time complexity grows with the number of elements. Not so with a bloom filter! A bloom filter is one of the few data structures whose time complexity does not grow with the number of elements due to the 'keys' not needing to be stored ('search' and 'insert' is based on the number of hash functions.) Bonus section: Golomb Coded Sets are similar to bloom filters but the stor

New best story on Hacker News: Tell HN: You can't hire because you don't post salary ranges

Tell HN: You can't hire because you don't post salary ranges 740 by Carrok | 394 comments on Hacker News. At the start of this year, Colorado has changed to require every job posted to list a salary range. Other states are also beginning to follow suit. I am currently job hunting. I started looking locally, everything lists salary ranges, perfect. I can know which positions to skip and which ones might be a good match right away. No need to waste time with 7 rounds of interviewing only to find out the salary is 50% of what I currently make. Now I've begun widening my search to remote work, as the idea of commuting to an office in 2022 is completely insane to me. Most jobs on nation-wide job boards do not post a salary range. I will not even click on those job postings. It's simply not worth it. Further, after seeing so many positions listed _with_ salary ranges, when I see one without a salary range it makes me feel like you have something to hide and are trying to t

New best story on Hacker News: Ask HN: I love programming but hate the industry. Can anyone relate?

Ask HN: I love programming but hate the industry. Can anyone relate? 387 by DanUKs | 294 comments on Hacker News. I love building and working - always have, always will. I've been programming for nearly 10 years, 5 of those professionally but the industry is literally destroying my soul and it has recently become crippling. I've been in all kinds of jobs, from start-ups to massive corporate companies. I'm forever building my own side projects as I love it, as well as love the idea of making my own living but as you all know, side hustles don't make money over night. I'm currently in a great job. By great job I mean, the money is really good, there's room to grow and the opportunities are endless... Yet I can't bare it. I can't bare the devs that go out of their way to work weekends without being asked, I can't bare the endless meetings, constant micromanagement, bringing the stress home to my family. I don't know where or who to turn to. Can a

New best story on Hacker News: Tell HN: Internet Archive is facing a Big 4 Publishers lawsuit

Tell HN: Internet Archive is facing a Big 4 Publishers lawsuit 395 by antiverse | 114 comments on Hacker News. Not sure why this isn't more prominently highlighted, but this is a very culturally significant project and a custodian of a tremendous amount of Internet and WWW-oriented history. I would imagine HN would put this at the forefront of the discussions happening here. I'm not affiliated, but I am a concerned netizen. All of us here have benefited from The IA. Please help raise awareness as to what is happening. Read more here, and elsewhere - https://ift.tt/VaEef7Z > In June 2020, four major publishers—John Wiley & Sons and three of the big five US publishers, Hachette Book Group, HarperCollins and Penguin Random House—filed a lawsuit against the Internet Archive, claiming the non-profit organization, “is engaged in willful mass copyright infringement.” > The lawsuit stems from the corporate publishers response to an innovative temporary initiative launched

New best story on Hacker News: Show HN: tere – A Faster Alternative to cd+ls

Show HN: tere – A Faster Alternative to cd+ls 365 by mgunyho | 194 comments on Hacker News. Hi HN! I wrote a small program to browse folders in the terminal. The main inspiration was type-ahead search in GUI file managers. There exist several programs that are similar (see the listing in the README), but none of them do it quite the way I like, and often they have a very complex UI and a ton of features. I tried to make something that is obvious how to use and gets out of your way. (I also wanted an excuse to learn Rust.) Let me know what you think!

New best story on Hacker News: Show HN: I built an app for when I talk too much in online meetings

Show HN: I built an app for when I talk too much in online meetings 433 by interleave | 189 comments on Hacker News. Hey HN! Alexis here, I’m a product manager and software developer in Berlin by way of New York. I want to show you this app I made – It’s like a "buddy" for those, like myself, who inadvertedly talk too much in meetings. The app gives me feedback and a little more in control of what I have influence over by: * Keeping track of how long I’ve been speaking * Catching myself before I talk too much * Developing a better sense of timing I truly love having conversations with people in real-life. But online meetings, especially group calls, tend to make me nervous. I can't read body language. The tone of voice, micro-experessions and social cues get lost. If you, too, accidentally talk too much too often, check it out "Unblah". Watch the quick 2-minute demo and download the macOS app over at https://unblah.me/ . Cheers! Alexis PS: There’s a whole FAQ
