A cafe in Dublin airport has a robot that delivers hot food orders! But it just sped off without letting the people get their food out.

When it came back it had a human minder. And when my order arrived, the same human bought it, saying she couldn't trust the robot.

This is a post about most AI.

#UnconfinedWalks Surprisingly fairly dry at lunchtime! (I was so surprised I almost forgot to take a photo at all). No photos from yesterday’s rather miserable ride to Wigmore Hall for Rhiannon Giddens’ brilliant concert

Waddle this way! The sign-making genius who kept Britain’s drivers (and ducks) safe Airports, road signs, animal warnings … Margaret Calvert revolutionised how Britain looked and her brilliantly clear designs are still used today. We meet the font legend and Porsche lover

It is always a pleasure to read about Margaret Calvert. Absolute legend. Her contribution to the look of modern Britain is immense.

#UnconfinedWalks Weather has generally continued being a bit grim hence the continued lack of photos. Plus yesterday I was up in Bradford for my Aunt Isma’s funeral (where the weather was definitely living up to northern stereotypes). Somewhat better today though

Currently peer reviewing an article that uses the term 'archive(s)' in the title, the key words, several times in the abstract, and c.50 times in the main text, yet fails to cite a single recognised archivist, archival theorist, or archives journal. This keeps happening. #archives

Grampy’s father’s went straight into the lace trade so far as I know. It seems to have been grampy’s older brother John’s time as a chorister at Southwell and King’s that opened the way to higher education with him and Clive preceding Grampy to King’s. You may be first with PhD though a few Oxford >
