Show HN: Animating the World of Van Gogh with Stable Diffusion and AnimateDiff [video] I know I'm very late to the game but tried to realize Van Gogh's work with AI. Workflow is quite straightforward, generated all the video samples through Automatic1000's Web-UI by leveraging SD1.5 + Motionv3 in AnimateDiff. Rendered everything on my RTX 3080TIM laptop. Took me decent 40 mins for different experiments and generations. https://www.youtube.com/watch?v=yntoe0i6QxY January 29, 2024 at 07:00AM

Show HN: 12-colored visual interactive music theory for pop/rock MIDI (+Github) https://bit.ly/3OllSF5

Show HN: 12-colored visual interactive music theory for pop/rock MIDI (+Github) I'm sharing an early prototype of my open-source interactive book and MIDI viewer. My approach is to annotate a tonic and phrasing in each file, so that chords become visible as 3-4 color bundles after a bit of training. This radically simplifies seeing and hearing chords, so that you can rapidly browse through many arrangements and study Western harmonic/arrangement language If you don't have a touchpad, a horizontal scrolling can be done via shift+mouse wheel (generally on the web). Also, I have a second color scheme that I tried to optimized for people with color vision deficiencies. My big dream now is to have all piano rolls in DAWs support 12-coloring (in any color scheme really), so that the music can be seen as less complex, less gatekeeped and less entangled. It's not as hard as I've seen it before. Source code: https://bit.ly/3uhWid9 It currently doesn't play music from Russia or Türkiye (=requires a VPN), because I rely on corsproxy.io internally which blocks access from those countries. I plan to rehost stuff on S3 soon to fix that. Also, it's more performant in Chrome than in Safari - audio clicks less. === Backstory: I quit Whatsapp in 2021 to focus full-time on studying music theory. Along that I've assembled a list of resources to see the frontier: https://bit.ly/3vMcZhi My biggest inspiration is Hooktheory - an interactive book that teaches how melody and chords interact in Western pop music. After it I wanted to study how the rest of the arrangement works - what the bass line is doing, how is melody doubled, what chromatic chords are possible, are there any functional pre-dominants and dominants in mixolydian or dorian etc. I wanted to focus on music for which the complete arrangement is clean and available. This is early chiptune (NES/Genesis) OSTs and MIDI arrangements (primarily created in 1990s). As I plugged MIDIs into my front-end, I discovered that the harmonic analysis - the cornerstone of studying Western harmony - can be done by eyes in real-time. That is, if you color the notes consistently, the chords start to stare at you, sharply and memorably. I'm intrigued by latest shifts towards corpus studies in music theory and I'm generally happy that nowadays the research is not just about classical music anymore. At least in the West. https://bit.ly/3Okbuxg January 28, 2024 at 02:37PM

Show HN: WAYF – A Simple Scheduling App https://bit.ly/3SeGKyX

Show HN: WAYF – A Simple Scheduling App A dead-simple web app to find the best time for your next meetup with friends. No logins, no bloat. Schedule with a link. --- When trying to schedule events with my friends, we often have a long text thread of sporadic dates and the group has to mentally combine all the messages to produce a date that works for all. There are plenty of apps out there to coordinate scheduling, but I found many of them were bloated with features that didn't matter to us, required user sign ups and app downloads. This friction is enough for us to prefer rudimentary long text threads. I wanted something that I could post in the thread once, my friends can add their availability on their own time (and can edit), and we can continue on our conversation. WAYF (When are you free?) is a fun side project that solves this issue. Bare-bones scheduling for what days you are free. No user accounts, no downloads, just paste a link and anyone can schedule. It's completely free. I hope you like it and find it useful, I would love feedback. https://bit.ly/42jqtNC January 28, 2024 at 12:39AM

Show HN: HNRelevant – Explore Related Discussions on HN in an Integrated Sidebar https://bit.ly/3Ui8a9H

Show HN: HNRelevant – Explore Related Discussions on HN in an Integrated Sidebar Reading submissions here, I often feel intrigued and want to explore more interconnected or similar stories. The process of googling and going back and forth didn't feel natural. So, I made this browser extension that adds a related submissions section for HN's layout. The results are displayed in a sidebar right in the page's layout using HN native style just like other elements. I enjoy being knee-deep in discussions. Many times you're learning about something new, where the topic is either unfamiliar, thought-provoking, or just could use some context that you don't even know about. If a submission is interesting enough for me to click on, chances are I'd like to dig deeper into this topic and there are more related discussions that offer new context or perspective. This is an extension that I always have on so I paid special attentions to UX to make it intuitive and seamless and now the extension has become just part of the HN experience for me. Implementation-wise, it integrates https://bit.ly/4b8mY0R API and uses the submission title as its initial query with the ability to change the query and other options interactively. It's available on: Chrome, Firefox, and as a userscript. Chrome: https://bit.ly/3UhNqPr ... Firefox: https://mzl.la/3vPDmTM I shared it earlier last year when it was early in development, barely a prototype, at the time it wasn't yet published and could only be used on chrome by "load unpacked": https://bit.ly/43aGmG1 . I've been using it daily since and I'm happy to share it now for you to give it a try. https://bit.ly/432w2jf January 27, 2024 at 11:39AM

Show HN: An efficient SRL32 (cascading shift registers) clock prescaler in VHDL https://bit.ly/495YJ1i

Show HN: An efficient SRL32 (cascading shift registers) clock prescaler in VHDL Having just started learning FPGA Hardware Description Languages by attempting to write a simple LED blinker, I found that the overwhelming majority of the Internet's solution to slowing down a fast clock (for making the pulsing of an LED visible to the human eye) was either using vendor-specific, proprietary clock managers and PLLs or implementing some twenty-something-bit-wide counter as to count hundreds of thousands of clock cycles and generate a 1 Hz output. Although there is a world of difference between counters in hardware-accelerated designs and those in software-emulated ones, I nonetheless viewed the number of daisy-chained components resulting from a mere counter as far-from-ideal and absurd; I began searching for a more efficient method. I came upon a rather obscure blog post from 2015 ( https://bit.ly/4b9h3Zf... ) outlining the exact same issue while also referencing the Xilinx systems designer Mr. Ken Chapman's proposal: using FPGAs' shift register primitives (e.g., Xilinx's SRL32E) to alleviate that. However, the method described therein would rely on the user to calculate the target frequency's factors between [2, 32) and painstakingly connect each and every instance of SRL32Es to one another, all in a manual manner, not to mention that the resulting pulse would have a low, one-cycle-long duty. Thus, I wrote srl_prescaler.vhd, a fully automated template generator in VHDL for an efficient register-based cascaded clock divider based solely on SRL32 primitives alongside AND gates---the advantage of this module is that it is very generic and easy-to-use: ``` prescaler : entity work.srl_prescaler generic map (100e6, 1) port map (clk_in_100mhz, ce_out_1hz); ``` In the above example, an input clock of 100 MHz (i.e., `100e6` & `clk_in_100mhz`) gets divided into a clock enable signal of 1 Hz (i.e., `1` & `ce_out_1hz`). Among the other improvements, a third optional parameter (i.e., the duty cycle) may also get supplied as a real number (0.00, 1.00) to the generic map. Overall, this small project makes an otherwise-niche method more accessible by actually making use of the many language features that VHDL has to offer (e.g., pre-computing factor results using functions, automating hardware creation via for...generate clauses, latching using registers and guarded signals, etc.), serving as a good yet practical learning point. https://bit.ly/3SlT8NQ January 26, 2024 at 10:00AM

Show HN: A self-hosted website to track Pinball scores between friends https://bit.ly/3StSxea

Show HN: A self-hosted website to track Pinball scores between friends Hi there! I have been a huge fan of pinballs for a few months, discovering all pinballs that are in my city, and I converted quite a few friends to it. The only problem was that we wanted to keep an eye on everyone's score and I always did it in some notes on my phone. This was not very practical. I decided to create a small website so that all my friends can add their scores while we're playing in a gig. The app is minimalistic on purpose: no user authentication, no call to any fancy Pinball API whatsoever. I just need a list of players, gigs, pinballs and scores. The app is built with Laravel and SQLite so it should be easily deployed anywhere. I personally host it on Fly for free (they have a generous free tier). One can add HTTP Basic authentication with a common user/password to avoid having anyone unkown messing with your data. The link to the repo is in the banner.
