Suzuki engine outrun navy and police boats 😂😂 What the new strategy could - with the advances in the drone technology, blanket the channel with the drones equipped with sensors and camera, all processed by AI, to give the law enforcement the threat inteligence to work with.

I am a happy use of @firefox.com hence the shambolic attachment of almost 5GB of large language model in the Google chrome does not affect me. Do you use Chrome? What do you make of this new development?

@stephenrobles.com have you experienced success with “Screen unknown callers”? I had to switch it off as it asked my wife for her reason for calling 😂. In fact it asked every caller despite many being in my contact list.

“Security theatre” - Security theater refers to security measures that make people feel more secure without doing anything to actually improve their security. — Bruce Schneier (www.schneier.com/essays/archi...) This hotel door security chain fits that definition perfectly.

read the fine print of your insurance policies; the most important section is called “Exclusions”. It is usually cheaper to put MFA in than later not being paid the insurance claim.

Hey there! I was wondering if potholes are similar to IT issues if we pay road contractors per pothole / IT issue? This approach doesn’t drives improvements. After all, contractors are motivated to fix as many potholes as possible, rather than focusing on long-term quality. What do you think?

This story resonates with me. Technology companies don’t communicate with parents sufficiently about the options available protect their family in these situations. That said, as a parent, I find it strange that it took them so long to even notice this, especially as their daughter is 8 years old.
