@cbgenealogy.ie If you can spare a moment, I'd love your feedback on my Irish surname cluster tool. I know a few exist, but I haven't found one that drills down to townland level and weighs each against its local population. downtheroad.dev/census/surna...
Screenshot of the "Where a surname lived" page on Down The Road, an Irish genealogy research site. The surname Duffy is entered with "All years" selected from census options 1821, 1901, 1911 and 1926. A summary reads: 33,183 records in 5,225 townlands of 20 or more people, across 32 counties. A map of Ireland shows townland outlines shaded in four blues by the share of residents carrying the name (under 5%, 5 to 15%, 15 to 30%, and 30% or more). The densest clusters are in Mayo in the west, the Monaghan and Louth area along the east-central border, and Donegal in the north, with scattered townlands elsewhere and few in the south. Below the map, a county list ranks Mayo (5,482 records), Monaghan (4,734), Donegal (4,468), Dublin (3,430) and Louth (1,817). A "Strongest townlands" table lists Inishard Island, Mayo at 17 of 23 residents (74%), Carrickloughan, Louth at 31 of 46 (67%), and Corlat, Monaghan at 65 of 98 (66%). A sidebar gives research tips: start with the darkest townlands, compare census years, check neighbouring townlands, and a note that a shared place is not proof of kinship.

@bbcnewsnight.bsky.social isn’t it problematic that your journalist refers to 16 African Americans Senators after the civil war as “16 Blacks” especially in this context. @mrjamesob.bsky.social

Bluesky total users and ChatGPT makes scraping easy.
Screenshot of a ChatGPT conversation on an iPhone showing a message from the user that reads, “When this hits 40,000,000 users hit me up. https://bcounter.nat.vg.” ChatGPT replies with a task card titled “Watch bcounter for 40M,” scheduled for 10:00 AM, and confirms: “Done. I’ll check the counter hourly and ping you when it hits 40,000,000.”

The Wanchurian Candidate.
Meme featuring a picture of Nixon, Reagan and Bush.  Below that is a picture of Donald Trump.  The meme asks you to combine Nixon's Paranoia, Reagan's Dementia, Bush's complete lack of knowledge, and you get "This Clown."  The poster doesn't know who to attribute this meme to.

I just had a heated discussion with a friend of a friend on Facebook most of the day. I won’t tell you their demographic, but they were a very charged up Trump supporter. Then Facebook started showing me this group on my feed. Check out the masthead

Switch off Facebook. Get your breaking news from somewhere else. You can find this in your app and desktop under "Other Notifications." Also, change everything above that, to in-app. If you like, you can keep your messenger notifications.
