Changing Bit by Bit
A new contest challenges people to use micro:bit computers to solve problems.
Could you use your computing skills to aid the fight against illegal animal hunting? How about tackling ocean pollution or monitoring animals under threat of extinction?
A new global challenge called Do Your Bit aims to get young people using their computing creativity to solve real-world problems. It’s being run by a partnership involving the BBC’s micro:bit computer, the technology company ARM and a campaign called World’s Largest Lesson, and it's aimed at people aged 10 to 16. It kicks off on 16 September.
The contest in 2019 is based on two Global Goals: to protect life on land and under the water. To take part, young people first choose a problem that affects them and their community, then design something involving the micro:bit computer that could help to tackle that problem.
Participants need to write up to 500 words about the problem and their solution, as well as providing a photo of their drawn plans or a hex file of their prototype code (编码), plus any other photos and videos showing what they’ve done.
This is the second micro:bit Global Challenge to be held. In 2018, the contest's winning designs included a homemade thief alarm, a classroom health monitor, a food-waste watcher and a device to remind people to sit up straight.
The deadline for entering the challenge is 28 February 2020: the winners will be announced the following month.

I looked forward to a visit with my mom, who lived 2,000 miles from my home in California. Since Mom was 80 and suffered from Alzheimer’s (阿兹海默症), I realized how important it was to see her again soon.
Mom received loving care from the Sister Servants of Christ the King at a 40-bed, basic-care facility (场所) in Edgeley, North Dakota. She lived in a simple room, spent most of her day doing simple things, and seemed to be “all right, “considering that dementia (痴呆) had set in.
When Mom came in, I smiled, hugged and kissed her, and said, “Nice to see you, Mom.” She didn’t recognize who I was! I was shocked.
Stressed out, I spent several hours trying to connect with my mother—talking with her, walking around the grounds, looking at family pictures in her room, chatting with the nuns (修女) —doing whatever I could think of to help Mom recognize her son. I hoped for a recognition “wonder”. But nothing I said or did worked, I was very annoyed.
The next morning, I suddenly had an idea. I thought of something that might stir her memory (记忆).I thought of strawberry milkshake (草莓奶昔). Yes, strawberry milkshake in Edgeley, North Dakota. So I took Mom to the Edgeley Coffee Shop. I wanted to treat her here. While Mom was looking at the menu, I took Sandy, the waitress, aside, quietly told her of Mom’s dementia condition and my plan to recall her long-term memory, and ordered two strawberry milkshakes.
The first paragraph: When Sandy delivered the milkshakes, I was too nervous to say a word.
The second paragraph: There’s a simple explanation for Mom’s memory.
