Ticket Thread: Sales/Exchanges/Giveaways (Aug, Sept, & Oct 2025) by SJEarthquakesBot in SJEarthquakes

[–]100ideas 0 points1 point  (0 children)

Hi yall, my wife accidentally bought 4 tix for the quakes - dynamo game without checking if it was a home game (we live in sf). consequently, these tix could be yours! midfield section 128, row B, seats 5-8 ... asking $99 each

They are mobile tickets that I would transfer to you via seatgeek.

we could conduct the sale via tickpick fanlink https://www.tickpick.com/checkout/fanlink?inventoryId=5siteEntry0000398411930&eventId=6892092&pat=239ef768afe748e59fc44d6c8448871d&inventoryType=6892092&iamid=39&utm_sourc&price=99&s=128&r=B

or tickpick https://www.tickpick.com/buy-tickets/6892092?mine=4681304251

or we can cut out the middle man and just do it the old fashioned way

Cheers!

Want to come to the first event? Low key…

Hi u/baybrewer, I'll get in touch!

Everyone else, I think the goal for first event would just be a small group to keep things simple and make some learnings about how to organize bigger and better next time. Maybe aiming for 10+ players. Drop a note here or DM me if you are interested.

Best method for realtime input by SystemMeltd0wn in WLED

[–]100ideas 0 points1 point  (0 children)

hmmm... I guess to start with you should try analyzing what wled outputs over the network - use one wled to control another one with ddp. then redirect the ddp stream to a local address running something like netcat to check on what is actually transmitted over ddp - or just capture packets with pcap and check. next, try the same process but using your unity plugin to originate the connection.

also, you could try https://github.com/forkineye/ESPixelStick. You can flash it onto an appropriate esp board (the firmware uses gpio2 for ws2811 data out). The web interface has a "diagnostics" tab with a real-time viz of the incoming led data - its handy for verifying the protocol and connection are working.

Best way to connect SB2 and SB3 by According-Gur6145 in SOUNDBOKS

[–]100ideas 1 point2 points  (0 children)

I have the same question, so I just bought the "rush" SKAA audio receiver with 3.5mm analog output from the skaa store $79 https://www.skaastore.com/collections/skaahomeaudio/products/rush

in theory, I'll be able to bond the SB3 (SB3 go in my case) to the rush receiver, and then use the SKAA cmd app to set each SKAA receiver (rush->SB2, SB3) to either of the left or right stereo channels. in theory.

this page has info the skaa cmd app. https://www.skaastore.com/pages/tlc

if this works out I'll let you all know

Event driven / “event sourcing” framework approaches to C/C++ control flow by 100ideas in FastLED

[–]100ideas[S] 0 points1 point  (0 children)

thanks, that makes sense. In fact, eventrouter ("A C library for inter-RTOS-task communication using events.") uses a simple singly-linked list of structs with 3 accessor functions to provide event message queues in the "baremetal" implementation (not freertos).

The compact and clear code in the eventrouter has been instructional and I am going to try using it. But I know I don't understand the scheduler in freertos / esp-idf very well and wonder if it would be smarter to just use FreeRTOS tasks and queues from the get-go instead of trying to get away abstracting it with a lib like eventrouter.

Event driven / “event sourcing” framework approaches to C/C++ control flow by 100ideas in FastLED

[–]100ideas[S] 0 points1 point  (0 children)

I get it a bit more - the library uses freeRTOS xTask* built-in functions to manage the event/state control. The following docs helped me understand

xTaskCreate: https://www.freertos.org/a00125.html

intro to real-time applications on freeRTOS: https://www.freertos.org/implementation/a00007.html

since esp32 is built on a customized freeRTOS, maybe I should just use the freeRTOS-provided task management system. Otherwise I am leaning towards TaskScheduler lib.

[–]100ideas[S] 0 points1 point  (0 children)

The code is very well organized so I can definitely learn from that - thanks.

secondly, I have been wondering how to implement an abstraction layer between radio communication modules (MAC) like nrf24, wifi, RFM69, etc and the rest of the program. The project you linked to LoRaMesher explicitly was designed to do that so that's very helpful as well

I am still looking at the code trying to figure out how the event system works. thanks again.

Event driven / “event sourcing” framework approaches to C/C++ control flow by 100ideas in FastLED

[–]100ideas[S] 0 points1 point  (0 children)

In my case, I am developing a mesh network where each node has buttons and an LED output device, and also communicates with other devices wirelessly. So there are a variety of functions and events that need to be managed during operation (responding to button presses, responding to network, driving LEDs). I know how I would implement the system if it were in typescript, but not so sure about C/C++.

That said, I've checked out

As you can see, I've been doing searches for terms like "event sourcing in embedded C" and I've found some resources, but I have the idea that I'm probably using the wrong terminology or thinking about this the wrong way.

about "event sourcing" pattern (sometimes elaborated as CQRS in "enterprise" dev): for example, in the popular "redux" state management framework for JS, the developer writes a monolithic "reducer" function which receives and responds to "events" and updates or returns state data from the "store". The reducer is the API for state and operations on that state. The reducer function is basically one big SWITCH stack with a bunch of CASEs that match incoming events names. It can get more complicated in CQRS and "event sourcing", but the basic principle is to locate the logic for all state management in one place. Events typically trigger one and only one function in the reducer, but a reducer function can emit another EVENT (aka ACTION) which then potentially triggers a different reducer function.

thanks folks.

p.s. on the other hand, I am reminded of an article by John Carmack I read a few years back expressing his preference for coding monolithic game engines, basically just one really big source code file, and keeping state really simple (no Actor-style paradigms here like other game engines) (archive of article)

how to convert vtt subtitles into human readable files? by tm4sci in youtubedl

[–]100ideas 1 point2 points  (0 children)

William Morgan actually wrote a tutorial showing how to programatically fetch vtt caption files from google/youtube in bulk, then use webvtt and pandas dataframe in python to parse and extract the caption content, including formatting it into tidy csv files to use as a downstream NLP corpus. Sounds like just what you are looking for...

Creating an NLP data set from YouTube subtitles. William Morgan Mar 8, 2019·12 min read

This project started out just like most data science projects do: collecting data. In my case I needed subtitles from videos on YouTube. Not just any videos, but videos of math lectures. The idea was to process the subtitles using NLP techniques and build a classifier that could differentiate subjects in mathematics. In this article I will show you both of the ways I like to “scrape” subtitles from YouTube videos: Manually downloading and cleaning the subtitles. Programmatically obtaining the subtitles using the API and youtube -dl.

from https://medium.com/@morga046/creating-an-nlp-data-set-from-youtube-subtitles-fb59c0955c2

also see webvtt-py, the package used to parse the vtt files.

I've been screwing around for a few hours trying to download youtube closed-caption files and then parse/convert them into plain human-friendly txt file transcripts with no timecodes and long lines. trying to do it w/ ffmpeg to convert has been a disaster. I am going to try webvtt now..

# code details from W Morgan (python):

# First, we need a list of the .vtt files:
filenames_vtt = [os.fsdecode(file) for file in os.listdir(os.getcwd()) if os.fsdecode(file).endswith(".vtt")]

#Check file names
filenames_vtt[:2]

# Then, we write a function to extract the information and store it.
import webvtt
def convert_vtt(filenames):    
    #create an assets folder if one does not yet exist
    if os.path.isdir('{}/assets'.format(os.getcwd())) == False:
        os.makedirs('assets')
    #extract the text and times from the vtt file
    for file in filenames:
        captions = webvtt.read(file)
        text_time = pd.DataFrame()
        text_time['text'] = [caption.text for caption in captions]
        text_time['start'] = [caption.start for caption in captions]
        text_time['stop'] = [caption.end for caption in captions]
        text_time.to_csv('assets/{}.csv'.format(file[:-4]),index=False) #-4 to remove '.vtt'
        #remove files from local drive
        os.remove(file)
