'Any evidence for Planet Nine is gone': Scientists dispute probability of mystery planet (cnet.com)

I remember the idea of Planet X as a kid. I assumed it wasn't real since we never got real evidence of it, but part of me always wondered if maybe it was out there. It seems the answer is no. Maybe it was a large comet that briefly got snagged by gravity but is gone now? No idea. An interesting read.

I have turned on the Mars mission's stream on YouTube and will be watching to follow Perseverance's attempted landing. I am incredibly nervous, this would be an amazing engineering and science feat if it works.

Incredible (twitter.com)


I watched the entire stream leading up to the landing, and grew increasingly nervous as everything went perfectly. I was afraid of some mysterious event and the loss of signal. With no clear way to know what happened. But instead it went smoothly and to plan. Simply incredible.

What Software Languages ​​does NASA Prefer for Rockets? (medium.com 🗝️)

Watching today's landing of the Perseverance on Mars, I was curious what it was coded in. A quick googling makes it seem like C is what they would be using on the rover. Fascinating stuff.

I continue my efforts to learn Python, tonight's project was to implement a calendar function. Python has a built in tool that does this, but it's about learning the language and implementing the tools for it. I was able to do it in about 60 minutes, with most of that being troubleshooting errors and learning some of the requirements for Python.

As I come from PHP, getting used to strict typing on variables is a big learning for me.

One of the common pitfalls I fall into is naming my files an obvious filename, which ends up being also something I import. For example, tonight's file was originally called 'calendar.py' but since I am importing the calendar library in python, it was erroring. So it got renamed to cal.py.

Here's the code I came up with:

import calendar
from datetime import datetime

date = input("Enter Date: ")

dt = datetime.strptime(date,"%m/%d/%Y")

header = datetime.strftime(dt,"%B %Y")

weekday = int(datetime.strftime(dt,"%w"))
date = int(datetime.strftime(dt,"%-d"))

month = int(datetime.strftime(dt,"%-m"))
year = int(datetime.strftime(dt,"%Y"))
firstDateOfMonth = int(datetime.strftime(datetime.strptime(str(month)+"/1/"+str(year),"%m/%d/%Y"),"%w"))

lengthOfMonth = int(calendar.monthrange(int(year),int(month))[1])

print(header)
print("[Sun][Mon][Tue][Wed][Thu][Fri][Sat]")

line = ""

if firstDateOfMonth > 0:
    k = 0
    while k  6:
        print(line)
        line = ""
        k = 0
    filler = " "
    if i == date:
        filler = "*"
    if i This code outputs a simple text calendar such as the following:
