Shameful that Google allows such blatant misinformation ad campaigns to feature prominently on the YouTube front page.

That's precisely what all the Trump apologists fail to see.
The current US administration is not only upsetting goodwill towards Americans in allied nations; it's decimating any trust held by all countries.
First, USAID, then all the crazy deportations, and now the VOA. Bye-bye American soft power

It is stunning how committed Trump is to removing American soft power, built up over generations.
“For the first time in 83 years, the storied Voice of America is being silenced,” Michael Abramowitz, the organization’s director, said
“VOA promotes freedom and democracy around the world … by providing objective and balanced news and information, especially for those living under tyranny.”

New, from me:
Trump is whitewashing American history, removing not just people, but also the stories, images, and values to anyone who does not conform to his impoverished vision of America.
Here is a partial inventory. 🧵

Canada, speaking as a non-citizen student, it's *Time for you to Build*
And please do a good job this time. Fix what needs to be fixed, be a land of opportunity, but don't let internationals continue to be exploited (nor let them exploit you).
(And also step up to the bullies down south.)

Optimal Bounds for Open Addressing Without Reordering
They show that, even without reordering elements over time, it is possible to construct a hash table that achieves far better expected search complexities (both amortized and worst-case) than were previously thought possible.
