Checkinarator Visualizer

Simple chart generator which displays checkins by those in the challenges

Running the App

This app is dockerized and can be both run locally or as a container.

Dependencies

This app uses poetry for dependency managment. Install poetry following the instructions on their site and then run poetry install. From there use poetry shell and then the entrypoint with python src/main.py.

Secrets

In order to access the data in the database DB_CONNECT_STRING needs to be set. This value is stored in a sops encrypted .env file and can be encrypted and decrypted using the scripts in ./scripts assuming you have access to an allowed key. Before you can access these secrets you'll have to generate a new age key pair and provide your public key to someone who already has access. Once they resign the secrete with your public key you'll be able to decrypt using the decrypt script.

Change Green Week calculation

This code probably won’t plug perfectly into what you’ve got but I’m posting it here in case it’s a useful starting point.

My goal is to have the probability of a green week ramp upward every week so there’s a guaranteed green week every 6 weeks, but never on the first week of a challenge.

After a Green Week, the probability ramp should reset.

Here’s the code and explanation:

@app.route("/make-it-green")
def make_it_green():
challenge_week = get_current_challenge_week()
week_number = challenge_week.week_number # Assuming this attribute exists

# Calculate the week number within the current 6-week cycle
week_in_cycle = (week_number - 1) % 6 + 1

# Define the probability for each week in the cycle
probabilities = [0, 20, 40, 60, 80, 100]

# Determine if it's a green week based on the ramping probability
green_chance = probabilities[week_in_cycle - 1]
green = random.randint(1, 100) <= green_chance

logging.debug("Is it green week: %s (Week %d in cycle, Chance: %d%%)", 
              green, week_in_cycle, green_chance)

if challenge_week.green is None:
    challenge_week.green = green
    challenge_week.save()

return render_template("green.html", green=green)

Let's break down the changes and explain how this new version works:

1. We calculate the week number within the current 6-week cycle:
   ```python
   week_in_cycle = (week_number - 1) % 6 + 1

This gives us a number from 1 to 6, representing the position in the current cycle.

2. We define a list of probabilities for each week in the cycle:

   probabilities = [0, 20, 40, 60, 80, 100]

   This means:

   • Week 1: 0% chance (never green)
   • Week 2: 20% chance
   • Week 3: 40% chance
   • Week 4: 60% chance
   • Week 5: 80% chance
   • Week 6: 100% chance (guaranteed green if not green yet)

3. We determine if it's a green week based on the ramping probability:

   green_chance = probabilities[week_in_cycle - 1]
   green = random.randint(1, 100) <= green_chance

   This checks if a random number (1-100) is less than or equal to the chance for that week.

4. We've updated the logging to show the week number in the cycle and the chance of being green.

This approach ensures:

• The probability of a green week increases each week within a 6-week cycle.
• Week 1 is never green (0% chance).
• Week 6 is always green if a green week hasn't occurred yet in that cycle (100% chance).
• There's a smooth ramp-up in probability, making later weeks more likely to be green.
• Each 6-week cycle is independent, resetting the probabilities.

This method provides a good balance between predictability and variability. It ensures at least one green week every 6 weeks while still maintaining an element of surprise for weeks 2-5.

Allow math inside calculator fields

Every day that I check in I use a calculator to add my minutes up from different exercises, then I put that number into the Tier Calculator. It would be awesome if I could do the math directly in the calculator field and have it added for me.

This might conflict with the PIN/numpad keyboard on iPhone. Maybe there’s another version that includes the basic calculator operators like plus and minus? Or you could do an on-page calculator style input?

Highlight highest tier on calculator

Reveal each item’s tier result and draw an outline around whichever of the two values results in the higher tier.

If they both result in the same tier, do not draw an outline.

Add numpad with operators to Tier Calculator

Looks like there is a way to get a numpad keyboard with operator symbols on iOS.

Looks like input type [decimal] or [tel] might get us what we want.

@trescenzi This is probably the kind of thing I could play with in the code myself to find out if it worked, if there was a way for me to test the output. But I have to imagine it would be a whole lot of extra work to make that possible?
