Noticias do Hacker News: Ask HN: YouTube Channels for the Intellectually Curious

Ask HN: YouTube Channels for the Intellectually Curious 651 by maxutility | 281 commentarios de Hacker News. As someone who is intellectually curious and has had great success finding articles on sites like Hacker News and blogs like kottke.org, I haven’t yet figured out where to find the most interesting content on YouTube. Let me know in the comments if you have found certain channels and creators to be particularly rewarding to follow, or if there are other ways you’ve found to consistently track down good content.

Noticias do 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? 760 by Uptrenda | 365 commentarios de 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 ...

Noticias do 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 737 by Carrok | 391 commentarios de 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 ...

Noticias do Hacker News: Show HN: tere – A Faster Alternative to cd+ls

Show HN: tere – A Faster Alternative to cd+ls 366 by mgunyho | 194 commentarios de 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!

Noticias do 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 434 by interleave | 189 commentarios de 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...
