Display Author Registration Date – WordPress Development Stack Exchange

In author archive, I want to show author registration date in the following format:

January 16, 2021

I have found this code:

$user_ID = $post->post_author;
echo the_author_meta( 'user_registered', $user_ID );

But its output format is:

2021-01-16 10:40:52

How can I strip off time and get my desired format?

I am using date format F j, Y

exchange rate – What caused bitcoin to fall ~$10k on 17 April 2021?

Bitcoin to USD exchange rate has been historically very volatile, but the recent (e.g. past 12 months) largest daily movements of ~$5k after Elon Musk tweeted about Telsa buying bitcoin, and ~$3k after Coinbase’s IPO. But a ~$10k fall is larger in magnitude than both of those major events combined.

Did any specific event(s) trigger this fall (and if so, what were they), or was it simply market volatility?

adding hotspot functionality – Android Enthusiasts Stack Exchange

I am currently trying to enable hotspot functionality on the relatively new 3.5″ Palm phone. Designed to be a companion phone to a larger, more fully-equipped phone on the Verizon network, now it is available unlocked. I would like to do the opposite and have this as my primary phone while using a larger phone as a companion when needed.

I have tried some hotspot apps, but thus far all seem to rely on the phone already natively having hotspot support. Are there any apps or other methods for imbuing hotspot capabilities to this type of phone, or is it forever limited to being a companion device?

L1 Norm Optimization Solution – Mathematics Stack Exchange

I am trying to find the solution for the following optimization problem:

$max_{w} {z^Tw – lambda ||w – w_0||_1}$
where $z, w, w_0 in R^{Nx1}$ and $z, w_0$ are known.

We let $s$ be the subgradient of $lambda ||w – w_0||_1, hspace{2mm} s in { {u | u^T(w – w_0) = lambda ||w – w_0||_1, ||u||_{infty} leq lambda } }$.

If we write $lambda ||w – w_0||_1 = max_{||s||_{infty} leq lambda} s^T(w – w_0)$, the objective function can now be written as:
$max_{w} min_{||s||_{infty} leq lambda} {z^Tw – s^T(w – w_0)}$
$min_{||s||_{infty} leq lambda} max_{w} {z^Tw – s^T(w – w_0)}$.

The first order condition for the inner objective function is:
$0 = z – s hspace{1cm} (1)$
Substituting (1) into the objective function,
$min_{||s||_{infty} leq lambda} s^Tw_0$.

Hence, this objective function can be simplified as,
$min_s s^Tw_0 text{ s.t } -lambda leq s leq lambda$.

However, if all the steps above are correct (which I am not very certain about), I am not sure how the solution of s from the “simplified” optimization above will help me solve for w.
The sequence of steps taken to solve the initial optimization problem was inspired by the following paper.

Any help on this is very much appreciated. Thank you.
