Python 3.13.0 : generates multiple deformed polygonal shapes .

Today I created this source code in python that generates eight random convex polygons. The idea was to create sprites for a 2D game: snowballs, boulders, or similar objects... Obviously I also used Sonet 3.5 artificial intelligence. You can find the source code on the pagure account in fedora.

#!/usr/bin/env python3
"""
SVG Polygon Generator

This script generates multiple deformed polygonal shapes and saves them as separate SVG files.
Each polygon maintains convex properties while having controlled random deformations.

Features:
    - Generates 8 unique polygonal shapes
    - Controls deformation through radial and angular factors
    - Maintains convex properties
    - Exports each shape to a separate SVG file
    - Uses random colors for visual distinction

Usage:
    python generate_svgs.py

Output:
    Creates 8 SVG files named 'polygon_1.svg' through 'polygon_8.svg'

Python 3.13.0 : Tested TinyDB on Fedora 41.

Today I tested the TinyDB python package on Fedora 41 Linux distro:

TinyDB is a lightweight document oriented database optimized for your happiness :) It’s written in pure Python and has no external dependencies. The target are small apps that would be blown away by a SQL-DB or an external database server.

The documentation for this python package can be found on the official website.

The install on Fedora 14 distro can be done with pip tool:

pip install tinydb

This is the source code I tested:

from tinydb import TinyDB, Query
import datetime

# Create a TinyDB instance
db = TinyDB('my_database.json')

# Define a schema for our documents
UserSchema = {
    'name': str,
    'email': str,
    'age': int,
    'created_at': datetime.datetime
}# Insert some sample data
users = [
    {'name': 'John Doe', 'email': 'john@example.com', 'age': 30},
    {'name': 'Jane Smith', 'email': 'jane@example.com', 'age': 25},
    {'name': 'Bob Johnson', 'email': 'bob@example.com', 'age': 35}
]

for user in users:
    db.insert(user)

# Querying all users
print("\nQuerying all users:")
all_users = db.all()
for user in all_users:
    print(f"Name: {user['name']}, Email: {user['email']}, Age: {user['age']}")

# Filtering data
print("\nFidig users older than 28:")
older_than_28 = db.search(Query().age > 28)
for user in older_than_28:
    print(f"Name: {user['name']}, Email: {user['email']}, Age: {user['age']}")

# Updating data
print("\nUpdatig John Doe's age:")
db.update({'age': 31}, Query().name == 'John Doe')

# Deleting data
print("\nDeletig Jane Smith:")
doc_ids = [doc.doc_id for doc in db.search(Query().email == 'jane@example.com')]
if doc_ids:
    db.remove(doc_ids=doc_ids)
else:
    print("No document found with email 'jane@example.com'")

# Adding a new field
print("\nAddig a 'city' field to all users:")
for user in db.all():
    user['city'] = 'New York'
    db.update(user, doc_ids=[doc.doc_id for doc in db.search(Query().name == user['name'])])

# Sorting data
print("\nSorting users by age:")
sorted_users = sorted(db.all(), key=lambda x: x['age'])
for user in sorted_users:
    print(f"Name: {user['name']}, Email: {user['email']}, Age: {user['age']}")

# Getting document count
print("\nTotal number of users:", len(db.all()))

# Closing the database connection
db.close()

This is the result:

Python 3.13.0 : Test the gi python package on Fedora distro linux.

The gi (GObject Introspection) Python package is excellent! It provides Python bindings for GObject-based libraries like GTK, GLib, and Secret Service. It enables you to write native GNOME applications in Python and access system services seamlessly.

First, install these Fedora packages:

[mythcat@fedora ~]# dnf5 install python3-gobject libsecret-devel
...
Package "python3-gobject-3.48.2-3.fc41.x86_64" is already installed.
Package "libsecret-devel-0.21.4-3.fc41.x86_64" is already installed.
...
[mythcat@fedora ~]# dnf5 install gnome-shell gnome-keyring libsecret
...

I used this simple python source code to test the gi python package:

import gi

# Specify the version of Gio and Secret we want to use
gi.require_version('Gio', '2.0')
gi.require_version('Secret', '1')

from gi.repository import Gio, Secret, GLib

def check_schema(schema_name):
    try:
        Gio.Settings.new(schema_name)
        print(f"Schema '{schema_name}' is available")
        return True
    except GLib.GError as e:
        print(f"Schema '{schema_name}' is not installed: {str(e)}")
        return False

def store_secret():
    schema = Secret.Schema.new("org.example.Password",
        Secret.SchemaFlags.NONE,
        {
            "username": Secret.SchemaAttributeType.STRING,
        }
    )
    
    Secret.password_store_sync(schema, 
        {"username": "myuser"},
        Secret.COLLECTION_DEFAULT,
        "My secret item",
        "Hello, World!",
        None)
    
    print("Secret stored successfully")

def get_secret():
    schema = Secret.Schema.new("org.example.Password",
        Secret.SchemaFlags.NONE,
        {
            "username": Secret.SchemaAttributeType.STRING,
        }
    )
    
    password = Secret.password_lookup_sync(schema,
        {"username": "myuser"},
        None)
    
    if password is not None:
        print(f"Retrieved secret: {password}")
    else:
        print("No secret found")

if __name__ == "__main__":
    print("Starting secret operations...")
    store_secret()
    get_secret()
    print("Finished secret operations.")

The result is this:

$ python test_001.py 
Starting secret operations...
Secret stored successfully
Retrieved secret: Hello, World!
Finished secret operations.

Python 3.13.0 : know this -OOt ?

Today, I follow the actions from NEMO the basic explorer files from linux and I found this: -OOt

This first source code:

#!/usr/bin/python3 -OOt

... this is new, and refers to Python compiler optimizations.

The -OOt par in the shebang line #!/usr/bin/python3 -OOt refers to Python compiler optimizations:

1. -O: This flag enables basic optimizations. It tells the Python compiler to optimize constants and global variables.
2. -O2: This flag enables more aggressive optimizations. It applies additional compiler passes to further optimize the code .
3. -Ot: This flag optimizes for size. It reduces memory usage by eliminating unused variables and dead code.

So, -OOt combines three levels of optimization:

• Basic optimization (-O)
• More aggressive optimization (-O2)
• Optimization for size (-Ot)

Python 3.13.0 : Testing ntplib on Fedora 42.

Today I tested the ntplib python package on Fedora 42 with the python 3.13.0 version.

This is the source code:

from ntplib import NTPClient
import socket
import os
import datetime

def sync_ntp_server(server_address='pool.ntp.org'):
    try:
        client = NTPClient()
        response = client.request(server_address)
        
        # Get the offset in seconds
        offset = response.offset
        
        # Calculate the drift rate (seconds per day)
        drift_rate = offset * 86400 / response.tx_time
        
        print(f"NTP synchronization successful. Offset: {offset:.2f} seconds")
        print(f"Drift rate: {drift_rate:.2f} seconds per day")
        
        # Apply the offset to the system clock
        os.system(f"date -s '@{response.tx_time}'")
        
        # Optionally, you can also apply the drift rate to the system clock
        # However, this is generally not recommended as it can lead to further drift
        # os.system(f"ntpdate -d {server_address}")
        
    except Exception as e:
        print(f"Error synchronizing NTP: {e}")

# Disable SELinux temporarily
os.system("setenforce 0")

# Sync with NTP server
sync_ntp_server()

# Print current system time after sync
current_time = datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S')
print(f"Current system time after sync: {current_time}")

The result is output is in the romanian language but this is not a problem for programmers:

Python 3.12.4 : DuckDB operate in in-memory mode.

DuckDB aims to automatically achieve high performance by using well-chosen default configurations and having a forgiving architecture. Of course, there are still opportunities for tuning the system for specific workloads. The Performance Guide's page contain guidelines and tips for achieving good performance when loading and processing data with DuckDB.

DuckDB can operate in in-memory mode. In most clients, this can be activated by passing the special value :memory: as the database file or omitting the database file argument.

You can use with python or another programming language.

I used Python 3.13.0rc1 version and pip tool ...

pip install duckdb --upgrade
Collecting duckdb
...
Installing collected packages: duckdb
Successfully installed duckdb-1.0.0

I created a python script :

python test_memory_duckdb_sqlite_db.py
[]
[('table', 'users', 'users', 0, 'CREATE TABLE users(id BIGINT PRIMARY KEY, first_name VARCHAR, last_name VARCHAR, occupation VARCHAR, hobby VARCHAR, year_of_birth BIGINT, age BIGINT);')]

This is the source code I used:

import duckdb

# Conectare la baza de date în memorie
con = duckdb.connect(database=':memory:')

# Instalează extensia sqlite
con.execute("INSTALL sqlite")

# Încarcă extensia sqlite
con.execute("LOAD sqlite")

# Verifică dacă extensia este încărcată
result = con.execute("SELECT * FROM sqlite_master").fetchall()
print(result)

# Conectare la baza de date pe disc
con_disk = duckdb.connect(database='sqlite_database.db', read_only=False)

# Instalează extensia sqlite pentru baza de date pe disc
con_disk.execute("INSTALL sqlite")

# Încarcă extensia sqlite pentru baza de date pe disc
con_disk.execute("LOAD sqlite")

# Verifică dacă extensia este încărcată pentru baza de date pe disc
result_disk = con_disk.execute("SELECT * FROM sqlite_master").fetchall()
print(result_disk)
