Although many presidents met with Queen Elizabeth, Barack Obama was the only President invited by the Queen to return after he left office. She reportedly regarded him as a pillar of integrity - a man of stability, decency, and rectitude.

We should stop confusing what someone was doing when we became aware of them with all they are capable of, interested in, or ever hope to be

Let folks have their many talents, interests and gifts. Life is far more fun with variety, loves.

A lot of folks have come to know me as an activist & I’m grateful that folks care to know me at all.

But I wasn’t born in 2014. I was a whole teacher, executive, policy person, speaker, arts and culture lover, reader, writer, woman of faith, fashion and more before 4 yrs ago 🤷🏾‍♀️

We rightfully complain that marginalized people are not allowed to be fully human.

But we internalize and transfer our oppression daily. It’s a smog. We all breathe it in & act it out.

And then tell WoC “girl ain’t you supposed to be a _______? Why you doing ____?”

Can I live?

And don’t go reading anything personal into this-this isn’t about me necessarily and it’s no subtweet (I try hard not to do that.)

I’ve just been observing that behavior more and more lately. Especially when it comes to marginalized folks.

Evolution should be our aspiration.

“Can’t knock the hustle” should be our anthem.

As long as someone isn’t bringing active and continual harm, why can’t they explore their many sides?

Important paper from Google on large batch optimization. They do impressively careful experiments measuring # iterations needed to achieve target validation error at various batch sizes. The main "surprise" is the lack of surprises. [thread]

The paper is a good example of lots of elements of good experimental design. They validate their metric by showing lots of variants give consistent results. They tune hyperparamters separately for each condition, check that optimum isn't at the endpoints, and measure sensitivity.

They have separate experiments where the hold fixed # iterations and # epochs, which (as they explain) measure very different things. They avoid confounds, such as batch norm's artificial dependence between batch size and regularization strength.

When the experiments are done carefully enough, the results are remarkably consistent between different datasets and architectures. Qualitatively, MNIST behaves just like ImageNet.

Importantly, they don't find any evidence for a "sharp/flat optima" effect whereby better optimization leads to worse final results. They have a good discussion of experimental artifacts/confounds in past papers where such effects were reported.

EVOLUTION OF CROWNS

The ancient Indian kings called a head crown as a Mukut and it would mostly constitute of a golden ornamental headgear like an oval cap with gems.

Sometimes it would also include a halo circle to show the divinity of the king

1/7

As it was considered that kings were appointment by the gods themselves. Example the kings of mewar considered themselves to be the ‘Diwan of eklingji')

But in most cases very few Mukut with halo effect have been found.

Samudragupta in the gupta era coin. You can see the helmet like headwear on him.

Till gupta era the solid golden head wear was used in most days of the monarch.

But since the onset of 8th century it reduced in usage and was now used only as a ceremonial headwear.

3/7

Whereas earlier the Maharaja had to wear the mukut whenever his court was in session.

Still mukut was being used prominently for ceremonial activities till recent times.

But as times past the style of headwear also changed.

The kings mostly wore turbans ordained with pearls and gems while rarely anyone wore a true Mukut after 16th century.

I had the most bizarre experience outside of a bar yesterday, which my partner very aptly described as "toxic mask-unlinity." (A Thread.)

I was standing outside, waiting for a lyft to get home, when two cis men came out of the bar to smoke cigarettes. They're discussing the masks that folks are wearing in California at the moment because of the very dangerous air pollution from the fires happening.

I happen to be wearing one of those masks, because I think lungs are important and I like breathing. I dunno. One of the men notices me standing there, and says, "Like this f*cker right here. What is this shit?"

He goes on a homophobic rant about me, the pansy with a mask, and what a Very Manly Man he is because he's not afraid to smoke a pack of cigarettes while California is on fire. He doesn't need a mask, because something-something-heterosexual-something.

And part of me is just... impressed by the fact that this dude thinks he's Owning The Gay Libs by not wearing a mask to protect his lungs from smoke and particles in the air that are literally DANGEROUS... while chain-smoking. Outside of a bar.
