Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Understanding continuity across an entire interval (epsilon-delta)
Copy and paste this comment into mathb.in to render the LaTeX.
-
Why do we multiply probabilities of conditions to get the probability of both conditions happening? Like why does it work that way?
You can render the LaTeX with the Chrome extension TeX Anywhere or by copying and pasting the comment into the mathb.in
-
How do I take density out of this derivative?
You can use the Chrome extension TeX Anywhere to render the LaTeX or you can copy and paste this comment into mathb.in which will render the LaTeX.

Ask HN: Most interesting tech you built for just yourself?
https://mathb.in/
I wrote this 11 years ago for my friends and myself who were going through a phase in our lives where we used to challenge each other with mathematical puzzles.
The use of this tool spread from my friends to their friends and colleagues, then schools and universities, and then to IRC channels. Now it is the oldest mathematics pastebin that is still online and serving its community of users. Visit https://github.com/susam/mathb for the source code of this tool.

Equation website?
Depends on the format, but maybe something like mathb.in? You can share LaTeX fragments.
- MathB.in - Share Mathematics with LaTeX and Markdown
- Building a Startup on Clojure
- MathB.in – Share Mathematics on the Web
- MathB.in - Mathematics Pastebin written using Common Lisp and JavaScript

Help with environmental parameters for a computer-controlled terrarium?
For controlling everything, the plan is to use a Raspberry Pi running Mycodo, which will connect to the the temperature/humidity sensors, and also control the LED lights, the misting sprayers, and the heating coil.

Grow light automation
As others have pointed out, there are quite a few alternatives already on the market, including open source ones. If you are attempting to turn this into a marketable product, you might be disappointed.

Fermentation Chamber 3rd generation
I'd also take a look at mycodo (here is the repo) which I personally found much more powerful than BrewPi and has an okay API I think if you want to set up your own frontend

IoT for hydroponics
Update: Found out about: MyCodo - https://github.com/kizniche/Mycodo (opensource Environmental Regulation System for rasbery pi) https://www.youtube.com/watch?v=nyqykZK2Ev4

Wireless sensors
Mycodo is great for the software side, but I don't think they have libraries for any wireless sensors.

Microsoft open sources its ‘farm of the future’ toolkit
There's tons of land unused in the US. But I also agree with you. I haven't played with this one yet, but it looks very nice

Timers?
Inkbird has a good reputation at a relatively low cost. Personally, I like to build my own systems using the Mycodo system running on Raspberry Pi W's.

Hydroponics: Growing an Appreciation for Plants
Here's my quick intro to hydroponics.
If you want bridge your grow with automation and coding I recommend everyone take a look at
https://github.com/kizniche/Mycodo
If you're looking for instrumentation/controllers for your grow (CO2, PH, TDS, EC) I recommend:
https://atlas-scientific.com/
If you're indoor and need lighting, build your own LED based lighting. Use the Samsung LM301B or LM301H led. I shopped https://atreumlighting.com/ for my last DIY kit and my light fixture came out perfect.
If you're buying nutrients or supplements, always try to get them in powered formula. Liquid based formulas are typically more expensive because you're paying to ship the water around and water is heavy. Most nutrient lines provide a feed schedule and dosing. When doing nutrients, less is more, never give them too much fertilizer, you will damage your grow and burn your plants.
Yes, I'm growing cannabis, you can see some of the fun we've had over the years at:

It’s less about the weed and more about the programming now. Having a blast with this little arduino. Two sensors per pot, 40 moisture-content readings per second. I also have data-logging capabilities via a data link from my laptop 🤙🏼.
Check out this environmental monitoring and control software I’m using on a raspberry pi with my grows, it’s amazing: Mycodo
