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!

Remember when Musk challenged the World Food Program to explain how he could solve world hunger with just $6 billion, they did, and he just completely ignored them?

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 (https://www.computing.co.uk/news-analysis/2026/anthropic-commits-200bn-to-google-cloud). 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.

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.

Today is quite significant for me personally. It marks the 30th anniversary of the day I started working at Sun Microsystems. I try to imagine how I would explain to younger me where I would be in thirty years. 😀
