I've been listening to the @virginmedia on-hold Jazz music for over 20 minutes (so far), and it's really starting to grate. Also, it's *really* unnecessary to tell me every 10 seconds that the lines are busy; I already deduced that!

I'll hold my hands up and say I'm no Python expert. So, can someone explain this? I type quit, and Python understands I want to quit, but tells me to type quit() rather than exiting. Explain to me why this is not the dumbest response possible.

Please, please @ubuntu, either make snap work so I can access files in the current directory or do away with it completely. It is utterly useless as provided.

Genuine question: What is the point of the Snap package manager on Ubuntu? I installed an app that is so sandboxed that it can't access files in the current directory, which is essential for it to work. Genini suggests I run it via a trusted Docker image. WTAF?

Outstanding customer service from @porterairlines. I fly from Ottawa to New York tomorrow and have checked in. To access my boarding pass, I need your mobile app. This isn't available to someone from the U.K. Why not?

How can a 27-slide PowerPoint presentation be 11.8MB? I deleted every slide with a picture (not many), and it's still 6.8MB. While I'm at it, what moron in the Microsoft UI group decided to relocate the compress picture option? 😡

Hi @aixenergy. Can you tell me how I can unsubscribe from your spam emails that I never signed up for? I have used the link that claims to unsubscribe me, but it doesn't. I even tried sending a direct email to spam@aixenergy.com, but that also failed. JUST STOP SENDING ME SPAM!

I was yesterday years old when I discovered that it's a *really* bad idea to remove the Python package from your Ubuntu installation. An awful lot of stuff suddenly stops working.

Great job @uber! Arrived at Heathrow Terminal 4 and none of your instructions for pickup are correct. App is wrong, website is wrong. Amazed if you get any business from here.

This quote is from an article in @computing_news (computing.co.uk/news-analysi…). How can anyone look at that and see any sense in it? AI bubble? What AI bubble?

This is the clearest explanation of AI and what it really does I have seen. Everyone needs to watch this, then spend some time reflecting on how you both perceive and use AI.
AI is giving every CEO the same advice

How does @Apple, @AppleMusic have so little understanding of how people use music? I have created playlists on an iPhone and want to export them. Just the playlist, not the music, so I can recreate it elsewhere. It seems easier to send people to the moon than to achieve this!

Having studied Physics at University, I am genuinely impressed that @Flighty believe we can taxi back in time. More details are required.
