I never really liked the term “10x engineer”, here's a better term
- The term '10x engineer' is criticized for being more of a buzzword than a genuine measure of success and growth, and its overuse makes it seem untrue in every case.
- A proposed alternative term is 'Self Guided Missile', describing individuals who can independently achieve goals like hitting a target without the need for micromanagement.
- These 'Self Guided Missiles' prefer to work autonomously to stay in flow state, complete tasks independently, and report back when done, based on personal experience.
- For startup founders looking to quickly build their minimum viable product (MVP) and enter the market, partnering with a 'Self Guided Missile' who can deliver the product efficiently could be more beneficial than hiring a team of below-average senior engineers.

Python for Oracle on ARM Linux | Part 2 - "shell like" SQL scripts
- Python can be a powerful alternative to shell scripting for Oracle DBAs, providing better readability and cross-platform compatibility.
- By using Python's subprocess module, DBAs can automate tasks like running SQL commands, managing script execution, and spooling outputs.
- Key benefits include integration with Python capabilities like data parsing, reporting, and automation frameworks.
- The essential Python module needed for these tasks is subprocess, which allows running programs such as sqlplus.
- Setting up variables like connection string, SQL file path, output file path, and command argument is crucial for the process.
- Subprocess is utilized with shell=True to run the SQL*Plus UNIX command and execute SQL scripts.
- An example SQL script provided in the article demonstrates data retrieval and JSON processing for weather data.
- A Python script 'py_ora.py' is created to run SQL files via SQL*Plus, redirecting outputs to a specified file for review.
- Running 'py_ora.py' in a miniconda environment successfully executes the SQL file and captures the expected outputs.
- The approach showcased emphasizes the use of Python over traditional shell scripting for Oracle DBA tasks, enhancing automation and maintainability.

Understanding the Key Differences Between IQueryable and IEnumerable
- IEnumerable is best for in-memory data collections and performs operations in memory with deferred execution for client-side filtering.
- IQueryable is ideal for querying data from a database, executing queries on the server with deferred execution and efficient data fetching.
- Use IQueryable for database queries to optimize performance, minimize client-side operations, and avoid eager conversion to lists.
- For in-memory collections, opt for IEnumerable to prevent unnecessary data loading and complexities of IQueryable usage.
