What is the difference between AI and cognitive computing?
The main difference between AI and cognitive computing is that AI is a branch of computer science that focuses on using computers to imitate human behavior while cognitive computing focuses on simulating the thinking process of human reasoning and decision making. AI focuses on rational decision making, while cognitive computing focuses on recognizing patterns and performing tasks autonomously. AI is more rule-based, while cognitive computing is more open-ended, learning and adapting as it goes.

How to log server messages in PostgreSQL?
You can use PostgreSQL’s built-inlogging capabilities to log the server messages. To enable logging, connect to the PostgreSQL server and use the following command to create the log file where the server messages will be written:
1. CREATE LOG FILE '/var/log/postgresql/serverlog.log';
This will create a log file named serverlog.log in the /var/log/postgresql directory. To enable logging, use the following command:
2. SET log_destination = 'csvlog';
This will enable logging of all server messages to the log file created in step 1. You can also set the log_statement setting to log all SQL statements executed on the server.
To view the log messages, simply use the following command:
3. \x
This will display all the log messages in a tabular format.
You can also use the pg_logfile_rotate() command to automatically rotate and compress the log file when it reaches a certain size.

Why do we need intermediate code?
Intermediate code is code that is generated by the compiler after translating source code into the target language. It is language-independent, which means it is not specific to any programming language and can be used by all. This allows programs and libraries written in different languages to interact with each other more easily. Additionally, intermediate code is easier to optimize and manipulate than source code, meaning that changes to a program are more efficient to make.
Intermediate code also makes the job of compilers much easier. Compilers would otherwise have to understand and convert each language from the source code into the target code, but with intermediate code, that task is simplified. This reduces the complexity and time of the compilation process for the end user.
