  Pasting from the Windows clipboard into a PuTTY  vi  or  vim  terminal can sometimes be problematic, particularly with newer  vim  versions that have mouse mode enabled by default.  This can lead to unintended visual mode activation or incorrect pasting.

AWS outage 2025 : More than 1,000 services were impacted by the outage, including popular platforms like WhatsApp , Snapchat and Reddit , which rely on AWS services, along with financial institutions like the British government’s tax services and entertainment services In India, the impact of the outage was most pronounced in the aviation sector, with hundreds of flights delayed and several cancelled as airline operators found their systems inoperational and had to switch to manual processes. At least ten banks and NBFCs had “minor disruptions”, which have either been resolved or are being resolved, the Reserve Bank of India said at the time. Here is a technical explanation for the AWS Outage due to a DNS failure . AWS's own internal control plane is built on top of DynamoDB . It's a hidden dependency. When AWS's internal services couldn't find the IP for DynamoDB, the entire management layer collapsed. Stage 1: DNS Fails. The internal DNS servers for dynamodb.us-eas...

Removing bash history in the terminal can be done in several ways, depending on whether you want to clear the current session's history, remove specific entries, or clear the entire history file. 1. Clear the current session's history: To clear the history of commands in the currently running shell session, use: ಕೋಡ್ history -c This command clears the in-memory history for the current session but does not affect the ~/.bash_history file until the session exits (and even then, it will only write the current, now empty, history). 2. Remove specific entries from history: To remove a specific command from the history, first, identify its line number using the history command. Then, use: ಕೋಡ್ history -d <line_number> Replace <line_number> with the actual line number of the command you wish to remove. To make this change permanent in the ~/.bash_history file, you need to write the current history to the file afterwards: ಕೋಡ್ history -w 3. Clear the entire bash history...
