Show HN: Betting game puzzle (Hamming neighbor sum in linear time) 13 by papa2fire | 0 comments In Spain, there's a betting game called La Quiniela: https://es.wikipedia.org/wiki/La_Quiniela_(Espa%C3%B1a) Players predict the outcome of 14 football matches (home win, draw, away win). You win money if you get at least 10 correct, and the prize amount depends on the number of winners. Since all bets are public, the number of winners and the corresponding payouts can be estimated for each of the 3^14 possible outcomes. We can also estimate their probabilities using bookmaker odds, allowing us to compute the expected value for each prediction. As a side project, I wanted to analyze this, but ran into a computational bottleneck: to evaluate a prediction, I had to sum the values of all its Hamming neighbors up to distance 4. That’s nearly 20,000 neighbors per prediction (1+28+364+2912+16016=19321): S_naive = sum from k=0 to r of [(d! / ((d-k)! * k!)) * (q-1)^k] (d=14, q=3, r=4) This took...

Show HN: Wampy, interface addon for Linux-based Walkmans 13 by unknown321 | 2 comments Wampy is an interface addon for modern Linux-based Walkmans, which allows you to switch between standard interface and custom one using hardware Hold switch. The project was born out of handful of standard UI nitpicks and "can I make a prettier UI?". There is no Rockbox port for my device (NW-A55), so I did a UI myself, unlocking and adding various features along the way, such as: - Winamp 2 skin support - Custom cassette skins - Digital clock skin ported from iPod Nano 7g - Audio amplification table editor for S-Master HX - All audio filters are available regardless of firmware - Per-song audio filter options - Standard interface enhancements (add clock and increase cover art size) - Low latency USB DAC module - FM radio on devices with FM chip and Walkman One (A40/50) The result covers 6 models, from cheapest NW-A30 to premium NW-WM1Z. Development process involved a lot of reverse engine...

Show HN: Hackyournews.com v2 3 by ukuina | 0 comments A year and a half after I published https://HackYourNews.com , I've rewritten it to be neater and added support for more news sources. HackYourNews.com v1 had a great response on HN [1] and consistently sees ~2k weekly unique visitors. There were many long-standing requests that I wanted to fulfill (thanks for your patience!): a proper dark mode, correct rendering on mobile devices, and more cogent summaries. This rewrite is the result. gpt-4o-mini reduces the cost of summarization to an absurd degree, so it's now sustainable to keep this free service going! Someday, I hope to use the Batch API [2] to drive down costs even further. Enjoy.

Show HN: A New Way to Learn Languages 30 by sebnun | 25 comments Hi HN, I’m Pablo, I built this application to learn languages using podcasts: https://www.langturbo.com (No signup required) There are a lot of tools to learn languages, but most of them focus on beginners (understandably so, that’s where the money is) but not many exist that target intermediate or advanced learners. The ones that exist make you find content on your own and then import that into their apps, which can be tricky when you don’t know where to look. LangTurbo has a unique curated database of podcasts by language (some even have dialect labels) that you can browse by topic, or search by keyword, so you can discover content and learn in the same place. Having a good language learning method is important, but having the motivation to keep learning is much more important. Some tools like Duolingo try to keep you motivated with “gamification”. I don’t like that, I think it gives you a false sense of accomplishment...

Cloudflare Is Blocking Pale Moon and other non-mainstream browsers 93 by Hold-And-Modify | 23 comments Hello. Cloudflare's Browser Intergrity Check/Verification/Challenge feature used by many websites, is denying access to users of non-mainstream browsers like Pale Moon. Users reports began on January 31: https://forum.palemoon.org/viewtopic.php?f=3&t=32045 This situation occurs at least once a year, and there is no easy way to contact Cloudflare. Their "Submit feedback" tool yields no results. A Cloudflare Community topic was flagged as "spam" by members of that community and was promptly locked with no real solution, and no official response from Cloudflare: https://community.cloudflare.com/t/access-denied-to-pale-moon-desktop-browser/764330 Partial list of other browsers that are being denied access: Falkon, SeaMonkey, IceCat, Basilisk.
