Y’all I’m so sad. I keep playing video games made by one or two people and now I want to make a video game soooooooo bad so I can design my perfect game and more importantly make the art. But!! Programming is my mortal enemy she and I do NOT get along. Maybe I could make something simple in terms of programming like a visual novel but I want more involved gameplay :,( I really want a fun video game project now
#daydreaming about making a programming friend who wants to work on a project with me#I have the game idea and everything just not the skills to make it#either I have to learn or I have to cry#anyways does anyone have suggestions for intuitive engines to build a game on?#I can use python I just fuckin suck at it#oh anyways I’m back#I was gone on a trip to visit my dad in the hospital in a nearby city#and I had nothing to do but play video games all day#hence my new ideas#but I’m back now!!#let the posting resume#lea talks

Simple Linear Regression in Data Science and machine learning
Simple linear regression is one of the most important techniques in data science and machine learning. It is the foundation of many statistical and machine learning models. Even though it is simple, its concepts are widely applicable in predicting outcomes and understanding relationships between variables.
This article will help you learn about:
1. What is simple linear regression and why it matters.
2. The step-by-step intuition behind it.
3. The math of finding slope() and intercept().
4. Simple linear regression coding using Python.
5. A practical real-world implementation.
If you are new to data science or machine learning, don’t worry! We will keep things simple so that you can follow along without any problems.
What is simple linear regression?
Simple linear regression is a method to model the relationship between two variables:
1. Independent variable (X): The input, also called the predictor or feature.
2. Dependent Variable (Y): The output or target value we want to predict.
The main purpose of simple linear regression is to find a straight line (called the regression line) that best fits the data. This line minimizes the error between the actual and predicted values.
The mathematical equation for the line is:
Y = mX + b
: The predicted values.
: The slope of the line (how steep it is).
: The intercept (the value of when).
Why use simple linear regression?

My friend showed me how to program today! I made a script to pick random items from a list, based on how much energy I have, to make it easier for me to do things every day :) !!!!!!!!!!!!!
(For context I am chronically ill and have massive executive dysfunction on top of that, so being told what to do early in the day depending on my energy makes things so much easier for me)


Ignore the excessive number of ++++ I made them for desktop and this is on mobile , I'll adjust it another time
Anyway I am VERY proud :D and greatful for my friend showing me!!!!
Also I'm already coming up for cool ideas on how to use this for art and fun little projects for my friends :)
I could program a choose-your-own adventure game AAAAAA!!!
Like I want to make one that asks what your name is and when a friend types their name in, it comes up with a little message/poem/ascii art picked just for them!!! Like I have a friend who's really into fanfic and I could have a fanfic or a reference come up, and another name would bring up a huge ascii penis, another name would bring up a poem I wrote for them- I'm losing my mind the possibilities are endless.
Oh also the guy who taught me is my bf's bf, who I want to be more than just boyfriends-in-law with so bonding like this is a boon for me because it shows me in a different light than "trapped by illness and depression"

omg hi fellow programmer i missed you too! good luck to you, i did oop in python and it was 💀💀 (i had to watch a few youtube tutorials to wrap my head around it [they all use the same car example which was really not helpful like i didn't get it until they used dogs to explain 😭 LOL you'll know what i'm talking about soon] but once you understand it, it gets fun). i'm here to wipe your tears away hehe good luck!! <33
#good luck to you my friend hope c-hash is a breeze for you#i finished python a few months ago and was polishing my skills you could say#and deciding what to do next#but i found my field (linguistics) related job a month ago and it's got me busy#and i have no desire to resume programming any time soon lmaooo i need to adjust to my new schedule first#i hope my skills don't get dusty in the meantime#tell me how it goes#chip <3#yumi.asks

There are so, so, so many reasons why this incredibly fake story is incredibly fake. But I just keep reading the API technobabble and I can't stop laughing.
Mf out here bragging about how not only is their code unreadable and unmaintainable, but also their documentation is unreadable and undiscoverable. The problem that this creative writer has is that they need to be indispensable in this story, but unfortunately an indispensable programmer is uniquely gifted at making themself superfluous as quickly and efficiently as possible in as many contexts as possible.
The "nobody is familiar with Python" part is probably my favorite. Python is one of the easiest programming languages to learn. It's so easy that it's the language that engineers (real engineers like chemical engineers, biomedical engineers, material engineers, not software engineers developers) use to help them automate things in their work. Anyone who is familiar with any other programming language can pick up Python in under an hour. You who are familiar with zero programming languages could probably pick up a decent amount of Python in a month. Try it! It is probably easier than you think.
More reasons why this fake story is fake:
This is posted on r/antiwork. It's one of the subreddits infamous for fake stories of bad bosses
It's a multipart series. One of the tropes of fake Reddit stories is the escalating updates. Creative writers hear an encore and they keep going back for more
It's a bit ambiguous how long this person has been in industry, but given the context of missing multiple children's school functions, I think 10+ years of experience is a cautious estimate. That is long enough in software for you to be a team lead, if not a people manager yourself. This person should be training junior devs. They explicitly say that they aren't
Software is incredibly collaborative. There's no way a manager would turn down an offer to train new devs on the existing tooling
Moreover there's no way the code got push to production without several eyes on it. Most companies do either code reviews or pair programming or both. It makes no sense that zero other people understand what's going on with this code. Unless it's really buggy
The fact that someone tried to use it and it corrupted a CSV file (??) shows that it's actually really buggy. If the software was so good, anyone would be able to run it
That goes double for the documentation being so bad that nobody knows how to read it. The entire purpose of documentation is to explain how code works. You failed at your one job.
If the only documentation is something that's hard to find, that looks bad on OOP for two reasons: 1) Documentation is normally put inline next to the code precisely for the reason that it would be easy to find. Don't want to see what a nightmare their code with no inline docs looks like. 2) Their programming practices are so bad that their other documentation is hard to find. The program should have a file called README that either has all the documentation or tells you where to find all the documentation.
This violates NDA so bad
"Out of compliance" for what? Which regulation? Why do they have a deadline to regain compliance? They should already be suffering whatever fines or consequences or whatever for already being out of compliance. It would make more sense if they were at risk of being out of compliance if they didn't implement XYZ by January
There's a lot of weird wording here that indicates a lack of familiarity with software: "complex API", "documentation library", "single threaded". That's not how we use those terms
If you're a software developer for a company the size of Disney (ABC's parent) then what OOP asked for is your starting salary straight out of undergrad. Def not a raise for a senior engineer who's been in industry 10+ years. Def not more than their manager is making.
At a company that size, your direct manager has no ability to decide what the terms of your hiring agreement would be. Def not over text. It would need to go through HR and probably legal as well
"Legal checked the contract and there's a clause stating" lmao get outta here!









#Reddit creative writing exercise#codeblr#progblr#You can learn almost any programming language for free online if you first learn the essential software engineer skill of#googling what you need#Im hesitant to pick a specific python tutorial because I havent needed a python tutorial in over a decade#I dont know which of the modern ones are good#Freecodecamp seems to be fine for JavaScript#Similar but imo superior language to start with

Understanding Outliers in Machine Learning and Data Science
In machine learning and data science, an outlier is like a misfit in a dataset. It's a data point that stands out significantly from the rest of the data. Sometimes, these outliers are errors, while other times, they reveal something truly interesting about the data. Either way, handling outliers is a crucial step in the data preprocessing stage. If left unchecked, they can skew your analysis and even mess up your machine learning models.
In this article, we will dive into:
1. What outliers are and why they matter.
2. How to detect and remove outliers using the Interquartile Range (IQR) method.
3. Using the Z-score method for outlier detection and removal.
4. How the Percentile Method and Winsorization techniques can help handle outliers.
This guide will explain each method in simple terms with Python code examples so that even beginners can follow along.
1. What Are Outliers?
An outlier is a data point that lies far outside the range of most other values in your dataset. For example, in a list of incomes, most people might earn between $30,000 and $70,000, but someone earning $5,000,000 would be an outlier.
Why Are Outliers Important?
Outliers can be problematic or insightful:
Problematic Outliers: Errors in data entry, sensor faults, or sampling issues.
Insightful Outliers: They might indicate fraud, unusual trends, or new patterns.
Types of Outliers
1. Univariate Outliers: These are extreme values in a single variable.
Example: A temperature of 300°F in a dataset about room temperatures.
2. Multivariate Outliers: These involve unusual combinations of values in multiple variables.
Example: A person with an unusually high income but a very low age.
3. Contextual Outliers: These depend on the context.
Example: A high temperature in winter might be an outlier, but not in summer.
2. Outlier Detection and Removal Using the IQR Method
The Interquartile Range (IQR) method is one of the simplest ways to detect outliers. It works by identifying the middle 50% of your data and marking anything that falls far outside this range as an outlier.
Steps:
1. Calculate the 25th percentile (Q1) and 75th percentile (Q3) of your data.
2. Compute the IQR:
{IQR} = Q3 - Q1
Q1 - 1.5 \times \text{IQR}
Q3 + 1.5 \times \text{IQR} ] 4. Anything below the lower bound or above the upper bound is an outlier.
Python Example:
import pandas as pd
# Sample dataset
data = {'Values': [12, 14, 18, 22, 25, 28, 32, 95, 100]}
df = pd.DataFrame(data)
# Calculate Q1, Q3, and IQR
Q1 = df['Values'].quantile(0.25)
Q3 = df['Values'].quantile(0.75)
IQR = Q3 - Q1
# Define the bounds
lower_bound = Q1 - 1.5 * IQR
upper_bound = Q3 + 1.5 * IQR
# Identify and remove outliers
outliers = df[(df['Values'] < lower_bound) | (df['Values'] > upper_bound)]
print("Outliers:\n", outliers)
filtered_data = df[(df['Values'] >= lower_bound) & (df['Values'] <= upper_bound)]
print("Filtered Data:\n", filtered_data)
Key Points:
The IQR method is great for univariate datasets.
It works well when the data isn’t skewed or heavily distributed.
3. Outlier Detection and Removal Using the Z-Score Method
The Z-score method measures how far a data point is from the mean, in terms of standard deviations. If a Z-score is greater than a certain threshold (commonly 3 or -3), it is considered an outlier.
Formula:
Z = \frac{(X - \mu)}{\sigma}
is the data point,
is the mean of the dataset,
is the standard deviation.
Python Example:
import numpy as np
# Sample dataset
data = {'Values': [12, 14, 18, 22, 25, 28, 32, 95, 100]}
df = pd.DataFrame(data)
# Calculate mean and standard deviation
mean = df['Values'].mean()
std_dev = df['Values'].std()
# Compute Z-scores
df['Z-Score'] = (df['Values'] - mean) / std_dev
# Identify and remove outliers
threshold = 3
outliers = df[(df['Z-Score'] > threshold) | (df['Z-Score'] < -threshold)]
print("Outliers:\n", outliers)
filtered_data = df[(df['Z-Score'] <= threshold) & (df['Z-Score'] >= -threshold)]
print("Filtered Data:\n", filtered_data)
Key Points:
The Z-score method assumes the data follows a normal distribution.
It may not work well with skewed datasets.
4. Outlier Detection Using the Percentile Method and Winsorization
Percentile Method:
In the percentile method, we define a lower percentile (e.g., 1st percentile) and an upper percentile (e.g., 99th percentile). Any value outside this range is treated as an outlier.
Winsorization:
Winsorization is a technique where outliers are not removed but replaced with the nearest acceptable value.
Python Example:
from scipy.stats.mstats import winsorize
import numpy as np
Sample data
data = [12, 14, 18, 22, 25, 28, 32, 95, 100]
Calculate percentiles
lower_percentile = np.percentile(data, 1)
upper_percentile = np.percentile(data, 99)
Identify outliers
outliers = [x for x in data if x < lower_percentile or x > upper_percentile]
print("Outliers:", outliers)
# Apply Winsorization
winsorized_data = winsorize(data, limits=[0.01, 0.01])
print("Winsorized Data:", list(winsorized_data))
Key Points:
Percentile and Winsorization methods are useful for skewed data.
Winsorization is preferred when data integrity must be preserved.
Final Thoughts
Outliers can be tricky, but understanding how to detect and handle them is a key skill in machine learning and data science. Whether you use the IQR method, Z-score, or Wins
