1. Show HN: Anki/Duolingo-like app using educational YouTube videos
Author: kirill5pol
Description: Hi HN,
I watch A LOT of educational YouTube videos but wasn't forgetting a good chunk of the details because I was only really passively watching. So I made a tool that generates quiz questions/flashcards from YouTube videos, and uses spaced repetition like Anki or Duolingo to keep it in memory.
Let me know if you find it cool/useful (or terrible ) or if you want to know a bit about the details!

2. Show HN: Alzheimer's Buddy: Use Flashing Light and Sound at 40Hz
URL: https://alzheimersbuddy.com/
Author: eigenvalue
Description: I recently learned about some fascinating research done at MIT for potentially treating Alzheimer’s using light and sound stimulation at 40 hertz. Nothing has been proven yet, but it seemed compelling to me, especially given the safety and simplicity of the treatment (i.e., no drugs, no electrodes, just looking at light and hearing sounds).
I wanted to try it myself, but was surprised how hard it was to find something free and easy to use to generate such pulses. Which is odd because I remember some freeware DOS program I tried back in the 90s which did all this kind of stuff (anyone know what I’m talking about? Google fails me…).
So anyway, I made this tool in a couple hours and put it up as a public service so that older people can try this treatment now without waiting years for FDA trials to finish and without getting a diagnosis and expensive piece of medical equipment. The code is available here:
https://github.com/Dicklesworthstone/anti_alzheimers_flasher
As an aside, I first tried making this in Rust, but gave up after finding it incredibly annoying to deal with the wgpu library with its ever changing and breaking API. This was a surprise because I generally find working in Rust to be quite pleasant.
In contrast, doing it in JS was a total breeze, and I was impressed how well canvas and webaudio works nowadays. It also makes it easy to add documentation right there on the page, to distribute it, and to get it working on mobile phones automatically. Web development is pretty awesome!
The best part is that, because I made it as a single html file on GitHub, I was able to deploy it without even setting up Nginx on a machine somewhere— I just used Cloudflare Pages and the whole thing took a couple minutes (getting the domain from Cloudflare made things even easier since they automatically handled everything with the certificate).
I realize that there are limitations in using a computer screen for precise flashing given hardware refresh rates. I’d certainly welcome any PRs if people have ideas about how to improve it or make it more efficient without breaking it on mobile. I tried to do the flashing in a way that can be easily hardware accelerated in modern browsers. The hardest part was getting rid of the disconcerting popping artifacts when starting and stopping the low frequency audio, but I resolved it by ramping up and down the volume beforehand.

Description: Howdy! I'm a recent PHP convert after a decade of laughing at PHP memes on r/programmerhumor, and wanted to dive a bit deeper into the language by building something practical with it. I also love beer and decided to combine the two by building a PHP library for the Open Brewery DB API (https://openbrewerydb.org/). Hope someone finds it useful!

8. Show HN: ChartBear, an API to create chart images in seconds
URL: https://chartbear.app/editor
Author: ilpes
Description: A few months ago, I was asked to build a reporting Slack bot for our internal stakeholders. This bot, among other things, had to send them some charts. During my make-or-buy process, I evaluated some services, but I wasn't totally satisfied with any of them, mainly for two reasons: firstly, because in most of those services, the data is sent as query parameters, and since the data in my case are sensitive, I didn't want that. The second reason was that the rendered chart images were not as cool as I wanted. I'm the kind of person who likes beautiful things .
So, I did some testing, and I realized there was room for a new API to create awesome charts in seconds. Therefore, I started drawing some wireframes of what would become ChartBear.

Description: FeedRiv is an open source RSS feed reader that I built as part of my 12 Startups in 12 Months Challenge (Open Source Edition). The open source code can be found on Github: https://github.com/dashboardq/feedriv
It is very minimal and probably a bit rough in some areas. I use it to track freelance jobs through RSS so it does what I need it to do.

16. Show HN: I Built a GitHub Action to Monitor LlamaIndex Performance
URL: #
Author: Ephil012
Description: Hi all, I had been working with tools like LlamaIndex at work and realized that there were not many good options for monitoring RAG systems for performance. So I built a pretty simple Github Action + PyTest setup to measure the performance of LlamaIndex over time. The setup basically uses a library called Tonic Validate, which scores the quality of your RAG system’s answers (Disclaimer: My current company made Tonic Validate and I am an engineer on Tonic Validate). Using Tonic Validate, it scores the responses from LlamaIndex on a set of test data I created and then uploads it to Tonic Validate’s UI for visualization. If anyone is interested in it, you can find the full source code here [1]. I also wrote a guest blog post on LlamaIndex’s blog about it here [2] if anyone wants more details about how it works.

Description: Hi, HN. In this video, I use ILLA Flow to schedule a PostgreSQL data query to trigger every day at 8 AM, then pass the latest data to the AI Agent. The AI Agent generates data reports, analysis suggestions, and more based on the latest data, and automatically sends them to Slack.
Looking forward to your review and feedback. If you are interested in learning how to build other automation tasks, please feel free to feedback.

18. Show HN: An efficient SRL32 (cascading shift registers) clock prescaler in VHDL
URL: https://gist.github.com/Thraetaona/ba941e293d36d0f76db6b9f3476b823c
Author: VioletVillain
Description: 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 (http://www.markharvey.info/art/srldiv_04.10.2015/srldiv_04.1...) 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:
<p>prescaler : entity work.srl_prescaler<p>generic map (100e6, 1)<p>port map (clk_in_100mhz, ce_out_1hz);<p>
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.
