I've started my own company and am about to launch our product, so I'm learning marketing. I think that I've been lucky so far because most of the traction is based on the strength of the product, and that has meant that I can sit back and gather feedback and opinions without doing anything outside of asking. However it's left me in a position where I'm unsure which steps I should be taking as I get closer and closer…

Same here. Good book reads: - The Mom Test - Build by Tony Faddel I’m reading IndieHackers.com every day. What product are you launching?

I've seen The Mom Test enough now that I need to read it, also, thanks for Build by Tony Faddel!

I'm trying to be as active as possible on IndieHackers. It definitely can be a good resource, it's just finding the posts which are actually good advice vs marking their own startups.

My current project is https://feetr.io which is a stock discovery algorithm, currently averaging ~4.1% daily increase per stock. Please feel free to give as brutal feedback as possible. You can message me here, through twitter (at twitter.com/feetr_io) or email at smcn@feetr.io.

My current understanding is that the "Maximum potential returns" just seems too unrealistic, despite it being the compounding interest of buying the best performing stock at open, and selling it at the highest point of that day. It's unrealistic that anyone could achieve that on a consistent basis but I personally have achieved over 1000% returns, and some of my beta testers have achieved much better than that.

Can you talk about how you are going about learning the piano? Ie. What study materials and how much practice you do? Piano is something I would love to learn too.

I'm working my way through Alfred's basic adult Piano Course. I like how it also teaches music theory. https://www.alfred.com/alfreds-basic-adult-piano-course-less... I went through it page by page, each day I started I'd go back maybe 5-10 pages. I do contrawise 2 handed scales as a warm up. I've been approaching it as work (ie concentrate hard, do deliberate practice not messing around) and have seen really fast im…

What brand piano are you using?

Make sure you have proper ventilation and air filtering for that 3d printer. https://3dinsider.com/3d-printer-fumes/

Thanks for the info. I'm not printing much yet (Few grams of filament a day) but 3D printing doesn't smell good, in any sense. Luckily I'm using PLA for printing, but I do plan to take the printer out to the balcony once I start printing "big" pieces.

Then wait until you have proper ventilation to start printing.

Self hosting on my own hardware. I’m not quite sure if this is “homelab”, but I mean things like Plex server, Kiwix with Wikipedia. NextCloud is… next.

Same here ! Just finished setting up plex, deluge, radarr, jackett on docker

For the past year, I have been learning Options Trading. I have taken on studying though books and implementing the strategies and ideas mentioned in books using Python/Pandas/Numpy/Matplotlib and variety of Options and Financial libraries.

OpenWrt and how to create programs to run on it. I'm trying to help a not for profit save some money managing weather stations

If possible, I'd recommend getting an OpenWRT wireless router where the GPIO (general purpose input/output) and UART pins are broken out. You can use that to control a relay and turn devices on/off from just the shell (eg: deploy the routers in pairs, and if one of them goes down, you can power cycle it using the other device). The UART port lets you access serial data devices (possibly through a 3.3V to 12V level converter) using Picocom.

For example:

1 Channel Relay Module with Optocoupler Isolation ~$4 https://www.aliexpress.com/item/2251832713449142.html

GL-MT300N-V2 OpenWRT router ~$27 https://store.gl-inet.com/products/usa-only-mango-gl-mt300n-...

GL-MT300N-V2 OpenWRT Specs https://openwrt.org/toh/gl.inet/gl-mt300n_v2

- UART pins

- GPIO pins available (requires soldering)

- 1x USB 2.0

Example of toggling GPIO44 10 times, then leaving it on:

    let GPIO_STATE=0
    for i in $(seq 10)
    do
      echo $GPIO_STATE > /sys/devices/virtual/gpio/gpio44/value
      # Toggle GPIO_STATE variable between 0 and 1 via XOR
      ((GPIO_STATE ^= 1))
      sleep 5 # sleep for 5 seconds
    done
    # Enable GPIO44 at the end
    echo 1 > /sys/devices/virtual/gpio/gpio44/value
