The Saudi informatics team, comprising Adeeb Al-Shehri, Hameed Al-Hudhali, Eissa Al-Moussa, and Djouri Al-Juhani, is competing in the 35th edition of the International Olympiad in Informatics (IOI 2023) held in Hungary with the participation of 360 male and female students from 90 countries.

The Saudi talents are participating for the fifth time in the activities of the IOI, the world’s most prestigious computer science competition for under-20 secondary-school students.

The IOI provides students with an opportunity to enhance their information science skills through problem analysis, algorithm design, data structures, programming, and testing.

Each participant is tasked with handling three assignments that involve problems to be solved within a five-hour timeframe.

From Homeless to Tour Guide: Londoners Lead the Way Round the Streets They Know Best

Stefan Gordon spent three years in a homeless shelter in London after a family rift left him without a roof over his head. Now he is using his past experience to tell the often hidden story of one of the capital's wealthiest areas.

Gordon, 31, is one of several formerly homeless people trained by Unseen Tours to lead guided walks in different London neighborhoods. The charity's aim is to reduce the stigma around homelessness and value people's potential.

"My view of homelessness is a person without a home... (but) just because they don't have a home, we can still do stuff," Gordon told Reuters as he led a group tour of Canary Wharf and West India Quay in east London.

In the 18th and 19th centuries the area, now the capital's business hub, was home to a large dock complex built to receive products such as sugar from the Caribbean, where enslaved people were forced to work on plantations.

The docks were created by and for merchants, but many of those who worked there were often badly paid and lived in poor conditions, something Gordon says he can relate to.

"Lots of people used to sleep in lodging houses and the hostel where I slept was an emergency lodging house so I kind of related a lot to that," Gordon said. "It was very, very tough back then... It's still tough now."

Gordon, who has autism, is now living with his mother and has been a guide since February. He gets paid 60% of the value of each tour ticket while the remainder is reinvested into Unseen Tours to cover operating costs and train new guides.

Unseen Tours' director of communication, Charlotte Cassedanne, said the guides, with help from the organization, research and design their own tours, and can incorporate their personal stories into their walks if they wish to do so.

They have been running for more than a decade, and 30,000 visitors have taken part in their tours. With six guides trained so far, Unseen Tours is currently fundraising to train three more.

"When you experience homelessness, you become sort of less than human... People ignore you daily... Putting them at the center of the storytelling really helps them have agency again," Cassedanne said.
