Patrick Stewart in the final scene on Star Trek: The Next Generation. It’s extremely simple, but reveals so much of his character if you watched. Somehow his sense of duty and sensitivity, along with the admiration of his crew shines through. RIP Captain.

One of PATRICK STEWART's greatest roles was Jean-Luc Picard in Star Trek: The Next Generation - a Captain who stood up for what was right. He delivered many great speeches in the role. This, from The Measure of a Man, is one of the best.

My small British company was bought by Americans. I have just been formally reprimanded for sarcasm and sardonic commentary. I told the disciplinary panel I was grateful for the opportunity to reflect on my attitude going forward and would be certain to bear it in mind in future.

It's called a cron job
is there an AI that can perform repetitive tasks? Ex: login into an app, perform certain tasks everyday?
