There's been a committed effort by people like Richard Hanania into mainstreaming race science and eugenics and it's, shamefully, mostly worked. Hanania in particular is a crude, blathering moron bigot using fourth rate statistics to justify his gutter bigotry

#30daychartchallenge day 10: multimodal.
I could probably find activities with even more variability but I was curious about the shape of how Canadians tend to spend their days across age: work, school, sleep.

Taking some Sunday inspiration for day 6: Florence Nightingale day. I did a coxcomb graph of the amount of time Canadians spend on DIY projects, by month. Big month coming up.

Forgot to add the data source again. It's the Canadian Time Use Survey! www150.statcan.gc.ca/n1/pub/45-25...

A simple one for day 5 of #30daychartchallenge: ranking.
A lollipop chart of the amount of time Canadians spend with different groups of people, at different ages.

Circle-packing dataviz depicting hours worked color-coded by workaholic-status.

Circle-packing dataviz depicting hours worked color-coded by workaholic-status.

Day 3 of #30daychartchallenge: circular.
Circles in a circle. Is it good dataviz? No. But it is circular. Canadians' self-reported workaholic status, each circle = 1 person, size of circle = hrs of work.
Basically, don't believe people who say they're workaholics.

Today in "Toronto's consultation process needs reform": the city sent me an invitation by mail to a consultation about a retroactive approval for an *enclosed front porch* about 5 doors down. Which we can't even see from the front or back of our house. Why should I get to weigh in on that!

General Social Survey – Public Use Microdata Files These public use microdata files (PUMF) from the General Social Survey provide data on social trends in order to monitor changes in the living conditions and well-being of Canadians over time.

Ah good catch, I forgot to include it here. The data is from the Canadian Time Use Survey: www150.statcan.gc.ca/n1/pub/45-25...

Honestly, I haven't been able to figure out the raw text files, so I'm just using the SAS data files provided. Unfortunately just for 2022 and 2005, so those are the years I'll be looking at.

Data visualization depicting a stark increase in self-reported time spent alone in the canadian time use survey from 2005 to 2022. Density plot below depicts two distributions with very different peaks.

Day 2 of #30DayChartChallenge: Slope.
Canadians spent a *lot* more time alone in 2022 compared to 2005. But that comparison is especially stark for young Canadians.

So glad to hear! It was a bit experimental so entirely possible the code could be more efficient/organized.

I decided I'll try to make all my charts for #30DayChartChallenge this year from a single data source - the Canadian Time Use Survey.
First up: Day 1 - Fractions. What % of Canadians don't get their 8h of sleep?

β€˜Climate of fear’: Montreal doctor says NYU cancelled her presentation A Montreal doctor says her presentation at NYU was abruptly cancelled and believes the university did so out of fear of being pressured by the Donald Trump administration.

NYU canceled a planned speech by the former president of Doctors Without Borders because she planned to discuss the humanitarian crisis in Gaza and cuts to US AID.

This is what actual campus censorship looks like.

Screenshot reading: 

"The sheer age of those COBOL systems is, oddly, actually something that works in their favour. Because they’re old, they have been relentlessly debugged. When a program is first written, it inevitably has problems. Sometimes it’s a typo, a misplaced command; other times, the user does something the programmer never expected, and things crash. When you get a new app, if it’s buggy and crash-prone, this is why: the creators sent it out into the world with lots of these little flaws. It can take days, weeks, or years to discover all the problems."

Also, *because* these COBOL systems are old ...

... the code is *very* bug-free

The maintainers have had decades to find and fix all the flaws in the system

In contrast, as any developer will tell you, the newer a code base is ...

... the more bugs it's gonna have, the more it'll crash

My cat was fully grey when he was found about 5 months ago. Now he's getting patches of orange which fully tracks because he's always behaved like an orange cat, brain cells-wise.

If you accept that non-citizens have no right to due process, you are accepting that citizens have no right to due process. All the government has to do is claim that you are not a citizen; without due process you have no chance to prove the contrary.

I understand the purpose and utility of centering these incidents but it would be nice if people just cared because other people's lives were being ruined and not potentially their own

The logic here was to take the top 10 words in 2023 (most recent year) and then backwards-map their frequency across the years. One clear outlier.

Yeah they're definitely not, but how close are we to genuine machine reasoning? I was more thinking about how human behavior is changing in response to AI models generally

With the rise of everyday LLM use, do we think people are getting better at describing things verbally, or just lazier and rely more on re-prompting? Or a third thing, purposeful and goal-driven alignment with LLM language to get the most out of prompts?
