On a bright, warm afternoon walking Muskoka Wharf, noticed a Public Outdoor Room (as A Pattern Language #69 describes) that provides shade and a social place to rest. My father said that he was out of town on the two days of construction May 1-2, 1993, by 60 tradespeople and volunteers, but was part of the Lions Club crew who later painted the ceiling white. The colour has changed, and the site is well maintained. Chatted with a woman looking after her grandniece, who remembered saying that such a project would never come to be. Father said he was on town council public works, and approved a suggestion to invite clean fill from excavated sites, filling in the marsh.

Storefront gallery @MakomTO installation @RDavidovitz (2020) What Will Remain stained glass sculpture has cracked panes, when inspected more closely. Toronto-based artist pays tribute to grandfather who would repair broken windows in post-war Vilna (then Poland, now Lithuania). On the eve of statutory holiday, few people on the street, except for pizza pickups next door. (Fentster / Makom: Creative Downtown Judaism, College Street West, Toronto, Ontario) 20200630
Association Rules in #RStats #MichaelEnquist @gta_r_users. Major grocery chain dataset with 50,000 customers, 37,000 merchandise items leading to sparse matrix. Apriori algorithm with support at 0.00001 results in 167000 rules. Unlike to run the complete dataset in a reasonable amount of time, more intelligence makes it a popular approach.
