Oracle Cloud World(OCW25) Tour Mumbai 2025 & Download – OCW-24 Resources
Posted by Sriram Sanka on January 8, 2025
Oracle has announced OracleCloudWorld(OCW25) Tour Mumbai 2025, which is scheduled On Feb 6, 2025, https://www.oracle.com/in/cloudworld-tour/ & you can check all the session details at https://reg.rf.oracle.com/flow/oracle/mumbai25/catalog/page/catalog.
BTW, Did you get a chance to download the PPT/PDF from the previous year? if not, you can refer to the following to download as needed.
Thanks to Connor for sharing the URL https://raw.githubusercontent.com/connormcd/misc-scripts/refs/heads/master/ocw_file_list in his blog post a few months ago.
source : https://connor-mcdonald.com/2024/09/20/the-cloudworld-2024-mega-download/
Here is the Python Code to go through all the lists and Download.
import os
import requests
# Define the URL containing the list of files
file_list_url = "https://raw.githubusercontent.com/connormcd/misc-scripts/refs/heads/master/ocw_file_list"
# Define the output directory for downloaded files
output_dir = "downloaded_pdfs"
os.makedirs(output_dir, exist_ok=True)
def download_file(file_name, file_url):
try:
response = requests.get(file_url, stream=True)
response.raise_for_status()
file_path = os.path.join(output_dir, file_name)
with open(file_path, "wb") as file:
for chunk in response.iter_content(chunk_size=8192):
file.write(chunk)
print(f"Downloaded: {file_name}")
except requests.exceptions.RequestException as e:
print(f"Failed to download {file_name} from {file_url}: {e}")
def main():
try:
# Fetch the file list
response = requests.get(file_list_url)
response.raise_for_status()
file_list = response.text.splitlines()
# Process each line in the file list
for line in file_list:
if line.strip():
# Split the line into file name and URL
parts = line.split(maxsplit=1)
if len(parts) == 2:
file_name, file_url = parts
download_file(file_name, file_url)
else:
print(f"Invalid line format: {line}")
except requests.exceptions.RequestException as e:
print(f"Failed to fetch file list: {e}")
if __name__ == "__main__":
main()
This creates a Directory called “downloaded_pdfs” and get all the resources listed on the above URL.
Just Save this file as ocw24.py and execute using python “python ocw24.py”
Having Session PPT/PDF helps individuals to focus more on the latest tech trends and learn. Hope this post helps you to learn new.

Which Load Balancer is right for you..?
Posted by Sriram Sanka on September 20, 2023
Oracle has Two Load Balancer Services available. , In case if you are not sure which one is best for you and what are the differences, you can refer the following chart provided by Oracle. https://cloud.oracle.com/load-balancers#
Load balancer
The load balancer service provides a reverse proxy solution that hides the IP of the client from backend application server and vice versa. It is capable of performing advanced layer 7 (HTTP/HTTPS), layer 4 (TCP) load balancing and SSL offloading.
Best for: Websites, mobile apps, SSL termination, and advanced HTTP handling.
Network load balancer
The network load balancer service provides a pass-through (non-proxy solution) that is capable of preserving the client header (source and destination IP). It is built for speed, optimized for long running connections, high throughput and low latency.
Best for: Scaling network virtual appliances such as firewalls, real-time streaming, long running connections, Voice over IP (VoIP), Internet of Things (IoT), and trading platforms.

Enable/Disable MFA on Oracle Cloud (OCI) portal
Posted by Sriram Sanka on September 12, 2023
When signing up, it is mandatory to configure and enable Multi-Factor Authentication (MFA). Once configured, during the login process, you will be required to obtain approval either through the Oracle Authenticator App or by obtaining a passcode.
To customise the MFA Configuration, access the Identity & Security section and select the desired domain. This action will direct you to the Domain Dashboard, where you can choose the appropriate security settings and explore additional options for Multi-Factor Authentication.
You can change the Default Configuration under Identity–>Domains–>Default domain–>Security –>MFA, when you try to update the changes , you may get the error as below “You cannot disable these factors as they are being referenced in Rules used in Sign-On Policies. Remove them from the Rules before disabling the factors.”
In order to prevent the occurrence of the aforementioned error, it is advisable to disable the default sign-in policy for both users and administrators as indicated in the error message.
Please note that it is not advisable to disable security policies and multi-factor authentication (MFA) for cloud access. follow https://docs.oracle.com/en-us/iaas/Content/Security/Reference/iam_security_topic-IAM_MFA.htm for more information.

Download Youtube ( Channel ) videos using Python Module – Pytube ,scrapetube.
Posted by Sriram Sanka on April 25, 2023
In this post, I will present the code to download Youtube Individual/Channel Videos step-by-step.
You can download the Videos using pytube module by passing the video URL as an argument. Just Install pytube and run as below.
python -m pip install pytube
This will download the given video URL to your current Directory, what about if you want to store your local copy for your educational purpose when you are offline.? The following will download the all the videos from the given URL to your desired location in the PC.
import requests
import re
from bs4 import BeautifulSoup
from pytube.cli import on_progress
from pytube import YouTube
from pytube import Playlist
from pytube import Channel
def get_youtube(i):
try:
yt = YouTube(i,on_progress_callback=on_progress)
yt.streams.filter(progressive=True, file_extension='mp4').order_by('resolution').desc().first().download('C:\\Users\\Dell\\Videos\\downs\\Sriram_Channel\\')
except:
print(f'\nError in downloading: {yt.title} from -->' + i)
pass
l = Channel('https://www.youtube.com/channel/UCw43xCtkl26vGIGtzBoaWEw')
for video in l.video_urls:
get_youtube(video)
You may get regular Expression error in fetching the video information due to changes implemented in the channel URL using symbols. or any other restrictions which are unsupported by the pytube module, either you have to download and install the latest or identify and fix it on your own.
To avoid this, you can use another module called scrapetube
pip install scrapetube
The following code will give you the Video id from the URL provided as input. you need to append ‘https://www.youtube.com/watch?v=’ to mark that as a complete URL.
import scrapetube
videos = scrapetube.get_channel("........t7XvGJ3AGpSon.......")
for video in videos:
print('https://www.youtube.com/watch?v='+ video['videoId'])
as you can see channel id is the key here, what if you are unaware of channel id.? You can get the channel id either from browser view page source or you can also use “requests” and “BeautifulSoup” module to get the channel ID
import requests
from bs4 import BeautifulSoup
url = input("Please Enter youtube channel URL ")
response = requests.get(url)
soup = BeautifulSoup(response.content,'html.parser')
print(soup.find("meta", itemprop="channelId")['content'])
Instead of using Channel from pytube module, to make it easier lets make changes to the original code snippet posted above, using module “scrapetube.get_channel “
import requests
import re
from bs4 import BeautifulSoup
from pytube.cli import on_progress
from pytube import YouTube
from pytube import Playlist
from pytube import Channel
import scrapetube
import json
def get_youtube(i):
try:
print('Downloading ' +i)
yt = YouTube(i,on_progress_callback=on_progress)
#print(f'\nStarted downloading: {yt} from -->' + i)
yt.streams.filter(progressive=True, file_extension='mp4').order_by('resolution').desc().first().download('C:\\Users\\Dell\\Videos\\downs\\Sriram_Channel\\')
except:
print('Error Downloading' +i)
pass
l = scrapetube.get_channel("UCw43xCtkl26vGIGtzBoaWEw")
for video in l:
#print('Downloading https://www.youtube.com/watch?v='+ video['videoId'])
get_youtube('https://www.youtube.com/watch?v='+ video['videoId'])
Hope you like it ! Happy Reading.

Reading Chrome Bookmarks using Python Module chrome_bookmarks
Posted by Sriram Sanka on April 24, 2023
Chrome Browser Bookmark file is in JSON format whereas history file is a database format. One can read the data file using SQLite(DB Browser) to get the URL and downloads data.
In this post I am using chrome-bookmarks module to read the bookmarks and print the URL along with it Name and Folder Information.
Install chrome-bookmarks module using pip
pip install chrome-bookmarks
Now you can read the URL from Python as below.
import chrome_bookmarks
for url in chrome_bookmarks.urls:
print(url.url)
We Can also print the URL Description/Name as below.
import chrome_bookmarks
for url in chrome_bookmarks.urls:
print(url.url, url.name)
import chrome_bookmarks
for folder in chrome_bookmarks.folders:
print(folder.name)
print(folder.folders)
It is also possible to read the JSON without using the above module.
import json
file ="C:\\Users\\Dell\\AppData\\Local\\Google\\Chrome\\User Data\\Default\\Bookmarks"
with open(file, "r", encoding='utf-8') as bookmarks:
bookmark_data = json.load(bookmarks)
print(json.dumps(bookmark_data, indent=1))
