How do you receive error alerts?

Nick Brunner — Wed, 17 Mar 2021 14:18:10 +0000

I've set up a cron job that runs a python script throughout the day on a machine I don't closely monitor. If the python script fails I'd like to receive a notification to my personal device so I can address the situation.

What would you or have you used in this situation?

Email? SMS? Something else?

Looking for a simple solution. Ideally, I'd prefer not to set up a new email for this use case.

Advent of Code 2020 - Day 3

Nick Brunner — Fri, 04 Dec 2020 05:52:00 +0000

Here is my solution to Day 3:

from typing import Tuple

with open('input.txt') as file:
    input = file.readlines()

puzzle_input = [line.strip() for line in input]

two_d_array = []
for line in puzzle_input:
    two_d_array.append([char for char in line])

horizontal_length = len(two_d_array[0])
vertical_length = len(two_d_array)

slopes = [
    {"horizontal_shifts": 1, "vertical_shifts": 1},
    {"horizontal_shifts": 3, "vertical_shifts": 1},
    {"horizontal_shifts": 5, "vertical_shifts": 1},
    {"horizontal_shifts": 7, "vertical_shifts": 1},
    {"horizontal_shifts": 1, "vertical_shifts": 2},
]

def over_three_down_one(
    current_row: int,
    current_column: int,
    horizontal_shifts: int,
    vertical_shifts: int) -> Tuple[int, int]:

    current_row += vertical_shifts
    current_column += horizontal_shifts
    if current_column > (horizontal_length - 1):
        current_column = (current_column%horizontal_length)
    return current_row, current_column

def traverse_slope(horizontal_shifts: int, vertical_shifts: int) -> int:

    current_row = 0
    current_column = 0
    tree_collisions = 0

    while current_row < vertical_length - 1:
        current_row, current_column = over_three_down_one(
            current_row,
            current_column,
            horizontal_shifts,
            vertical_shifts)
        if two_d_array[current_row][current_column] == '#':
            tree_collisions += 1

    return tree_collisions

answer = 1
for slope in slopes:
    answer *= traverse_slope(slope['horizontal_shifts'], slope['vertical_shifts'])

print(f'Answer: {answer}')

Did you solve it differently?

Advent of Code 2020 - Day 2

Nick Brunner — Fri, 04 Dec 2020 05:48:00 +0000

Here is my solution for Day 2:

with open('input.txt') as file:
    input = file.readlines()

puzzle_input = [line.strip() for line in input]

# First Challenge
valid_passwords = 0

for item in puzzle_input:
    split_item = item.split()
    min = int(split_item[0].split('-')[0])
    max = int(split_item[0].split('-')[1])
    letter = split_item[1].replace(':', '')
    password = split_item[2]

    occurances = password.count(letter)
    if occurances >= min and occurances <= max:
        valid_passwords += 1

print(valid_passwords)

# Second Challenge
valid_passwords = 0

for item in puzzle_input:
    split_item = item.split()
    first_position = int(split_item[0].split('-')[0])
    second_position = int(split_item[0].split('-')[1])
    letter = split_item[1].replace(':', '')
    password = [char for char in split_item[2]]

    if password[first_position-1] == letter:
        if password[second_position-1] != letter:
            valid_passwords += 1
    elif password[second_position-1] == letter:
        valid_passwords += 1

print(valid_passwords)

Advent of Code 2020 - Day 1

Nick Brunner — Fri, 04 Dec 2020 05:45:43 +0000

Here is my solution for Day 1:

with open('input.txt') as file:
    input = file.readlines()

puzzle_input = [int(line.strip()) for line in input]

for i in range(0, len(puzzle_input)):
    for j in range(i+1, len(puzzle_input)):
        for k in range(j+1, len(puzzle_input)):
            if (puzzle_input[i] + puzzle_input[j] + puzzle_input[k] == 2020):
                print(f'Answer: {puzzle_input[i]*puzzle_input[j]*puzzle_input[k]}')

Advent of Code 2020

Nick Brunner — Wed, 02 Dec 2020 22:09:35 +0000

Is anyone participating in Advent of Code this year?

From the website:

Advent of Code is an Advent calendar of small programming puzzles for a variety of skill sets and skill levels that can be solved in any programming language you like. People use them as a speed contest, interview prep, company training, university coursework, practice problems, or to challenge each other.

You don't need a computer science background to participate - just a little programming knowledge and some problem solving skills will get you pretty far. Nor do you need a fancy computer; every problem has a solution that completes in at most 15 seconds on ten-year-old hardware.

I just found this website and I'm planning to attempt each day's challenges. I'm going to try to post my solutions, in python, each day as well. I'd be interested to see how you all solved the challenges as well!

Neighbor

Category Submission: COVID-19 Communications

Intro

One sunny day of quarantine while walking my dog, I noticed someone had flyered every car on multiple blocks with a letter. The letter was a simple offering to anyone who needed assistance during this challenging time of quarantine. Inspired by this act of kindness, I set out to find a way that I too could help my fellow neighbors. My love of software quickly led me to the idea of this app and with the help of a friend, we created Neighbor. If you are also looking to provide assistance to those who may be at risk or may need extra assistance, I encourage you to sign up on our platform as a provider and share this app with others so we can spread the kindness.

Description

Neighbor is a free platform designed to connect those who need assistance with those who are willing to provide it. After signing up, Neighbor uses your location to match you with others in your area who can either provide assistance or are seeking assistance. Neighbor offers a chat interface so neighbors may communicate the specifics of their needs and make arrangements with others.
