Cloudflare SSL certificate not cover www.sub.domain.com

I have a website (prototype website for the lab where I am the research assistant). It is under chenpan.xyz, and I deployed an SSL certificate for www.sub.chenpan.xyz (I am a WWW friend now!).

Like my other websites, I enabled Cloudflare for it. But it stopped working! I got the following error from the browser:

This site can’t provide a secure connection.

www.sub.chenpan.xyz uses an unsupported protocol.

I had received calls from Amazon drivers asking if I would like my packages delivered for months, and today I finally fixed this issue

For months, I had received calls from Amazon drivers asking me if I would like my packages. “Of course”, I would always tell them. But still, I was wondering why this happened so frequently.

Until probably two months ago, I asked the Amazon driver why you always asked me this question. I thought it was their fault. But he told me, “you left an instruction saying you want the order cancelled, please not deliver the item”.

Well, it came to my mind that, yes, I did leave such instruction for an order. I didn’t notice that this instruction was saved and used for all future orders.

But now I think it makes sense, it is the instruction for the delivery at this address – the address doesn’t change, neither does the instruction.

Procrastinated for two months, I finally remembered to erase this instruction.

Receive my first COVID-19 dose on May 9

Waiting for vaccine
Waiting for vaccine

Going to receive my first COVID-19 dose tomorrow.

I recovered 100% about two days after the shot.

I will have my second does in late August. Almost four months hope that as more vaccine doses are coming, the appointment could be advanced.

By the way, the vaccine I received was Moderna. I preferred Pfizer actually, but what vaccine is used depends on what vaccine doses are delivered on that day. So, there is no option. And Moderna is using the same technology (mRNA) as Pfizer, so I don’t think there will be a big difference.

The doctor told me the protection rate would be 85% two weeks after the first shot, so, I plan to visit the university for the first time since March 2020, this Sunday.

Personal Website Update: Hover Panel

I was doing a refurbishment for my personal website right here. The idea came from Felix Wong.

In the hover panel, first thing first, there is the area for the menu. Below the menu, there is a search bar. Under the search bar, there is an area for widgets. In the end, there is the menu for switching languages.

The button itself is the picture used as the Site Icon for Twenty Twenty Theme. The width of the hover panel is 76% or 38.2 (the golden ratio) depending on the screen size. The opacity is 0.9, which is “semi-transparent”.

Felix proposed a good question that for some devices, the position of the notch might affect the visibility of the hover panel button.

To resolve this, I am thinking about the following solution:

First: I need to write some script to detect the position and shape of the notch. I hope that I can do it with JavaScript only.

Second, I need to check if the notch influences the visibility of the hover panel.

Lastly, if the notch doesn’t exist or it doesn’t matter at all, no action is required. Otherwise, I need to adjust the padding-top of the hover panel to prevent it from being overlapped.

For fun: “If you’re reading this …”, I saw this easter egg at the new wh.gov

I saw this line of code at the latest wh.gov. It is so interesting!

** Trump’s White House uses WordPress, so does Biden’s White House. Is it one of the few things they have agreed on as well?

Just noticed that the founder of WordPress, Matt, found this secret comment as well: https://ma.tt/2021/01/new-whitehouse-gov/
