Study Notes

Python

Python is open source.

AWS

EC2 (Elastic Compute Cloud): Provides resizable virtual machines, billed by usage.
EBS (Elastic Block Store): Offers persistent block-level storage, billed by provisioned capacity.
AWS Lambda: A serverless, event-driven compute service, allowing code execution without server management.

JavaScript

JavaScript allows code execution on events (e.g., button clicks).

DevOps

DevOps aims to improve communication between development and operations teams.
DevOps helps maximize efficiency in delivering and maintaining software applications.

SQL

A query to extract names from email addresses ending in @gmail.com:

SELECT SUBSTRING_INDEX(email, '@', 1) AS name
FROM your_table
WHERE email LIKE '%@gmail.com';

jQuery

Check jQuery version using:

$.ui.version || console.log(jQuery().jquery);

Cloud Computing - AWS

AWS Lambda: Serverless computing provided by Amazon Web Services, allowing code execution without server provisioning.
EC2 (Elastic Compute Cloud): Resizable compute capacity in the cloud, used for tasks like application running, website hosting and processing data.
IAM (Identity and Access Management): AWS service for securing access to AWS resources and services.
SQL Data Representation: Data is stored in rows and tables.
SQL Operator for Range: The BETWEEN operator is used to specify a range in SQL queries.
McCabe Number: A measure of software program complexity, calculated by the number of linearly independent paths.
Cloud Formation: Cloud computing services that provide methods to build, deploy and manage cloud resources and applications.
Continuous Integration in DevOps: Developers periodically merge their code into a repository to run automated tests, detecting issues promptly.

Data Structures

List, Tuple, Dictionary, Set: Python data structures.
Tuples are immutable, lists are mutable.

Database Transactions

Database transactions can be rolled back to revert changes.

Cloud Storage

Amazon S3 (Simple Storage Service) is object storage.
EC2 is not a cloud storage service.

Data Analysis in Cloud

AWS uses services like Redshift, DynamoDB, and Athena for large data analytics.

HTML

The name attribute in HTML is not an obstacle for <a> tags.
The name attribute can be used to create named links for users to navigate to specific sections on a page.

Unique Keys

Unique keys in a database do not accept NULL values.

Data Analytics

AWS offers data analytics tools for large datasets.

Agile Methodology

Agile methodology uses early and faster access to the customers' needs for software development.
