2nd maintenance of my blog

Due to the excessively high Node.js version on my Windows system, I was unable to deploy my Hexo blog. I spent yesterday afternoon doing some maintenance on the blog.

The last maintenance was to deploy the Twikoo comment section, which involved upgrading the NexT theme from version 7 to 8.1.0. It was quite a hassle and took a considerable amount of time.

I can only say that after numerous trials of configuring environments, my efficiency has improved significantly compared to before.

Steps

In reality, these three updates did not solve the fundamental issue of being unable to deploy the blog. Countless blog posts online uniformly suggested downgrading Node.js to a version below 12. How could I tolerate such a regression? Eventually, I found the final solution in this link.

@WinterSoHot
It seems caused by hexo-fs. hexo-deployer-git depends on hexo-fs and hexo-fs@2.0.0 is incompatible with Node.js 14.

We have already released hexo-fs@2.0.1 that supports Node.js 14.
Would you please re-install hexo-deployer-git?

I think, after re-install hexo d will work well.

Changes

Of course, going through all this trouble did bring some benefits, such as:

And some minor changes:

—Though it also came with some losses:

Tests

Excerpted from the Interval Estimation (Memorize) section of "(Completed) Probability and Statistics Notes".

Estimate the (1α) confidence interval for μ.

Estimate the $(1-\alpha)$ confidence interval for $\mu$.

If σ2 is known, it is (Xσnu1α2,X+σnu1α2)

If $\sigma^2$ is known, it is $(\overline{X}-\frac{\sigma}{\sqrt{n}}u_{1-\frac{\alpha}{2}}, \overline{X}+\frac{\sigma}{\sqrt{n}}u_{1-\frac{\alpha}{2}})$

If σ2 is unknown, it is (XSnt1α2(n1),X+Snu1α2(n1))

If $\sigma^2$ is unknown, it is $(\overline{X}-\frac{S}{\sqrt{n}}t_{1-\frac{\alpha}{2}}(n-1), \overline{X}+\frac{S}{\sqrt{n}}u_{1-\frac{\alpha}{2}}(n-1))$

Estimate the (1α) confidence interval for σ2.

Estimate the $(1-\alpha)$ confidence interval for $\sigma^2$.

((n1)s2χ1α22(n1),(n1)s2χα22(n1))

$(\frac{(n-1)s^2}{\chi^2_{1-\frac{\alpha}{2}}(n-1)},\frac{(n-1)s^2}{\chi^2_\frac{\alpha}{2}(n-1)})$

It seems the \overline{X} bug has indeed been fixed, and using a single $ for inline formulas no longer causes rendering failures.
