I use file system to manage my knowledge base. The repository has a well defined directory structure. I have a bunch of scripts to help me creating these directories on the laptop. But in iOS, I have to create them manually. Recently, I have found out a way to work around it via Working Copy.
Pin is an obscure type in Rust because of the naming and indirect concepts. The first indirect concept is pointer. Pin<X> does not guarantee that X will not move. If X is a pointer which target type is T, Pin<X> guarantees that T will not move. The second is “not move”. It really means that the only way to get the mut reference to T is via unsafe interface. The last is the Unpin mark trait. Pin forbids safe interface to get the mut reference to T only when T is !Unpin. In simple words, Pin is a pointer wrapper. When a pointer is trapped inside Pin, and the pointee type is !Unpin, there’s no safe way to get a mut reference to the pointee.
I have created a family group using the Apple ID A, and the account B is a member. However, I can’t download apps purchased by A in the device logged in by B. Today, I finally find out the cause. The Purchase Sharing setting in account B is incorrect, which is by accident set to share as A and I don’t know why.

Excel is a full featured vector graphics app. It has bundled many shapes and styles, and even supports anchoring connectors to the shapes. All these features make Excel also a good diagram maker. One of my favorite tips is grid snapping, it can save a lot of time to align shapes. I also recommend resizing the grid as small squares.

I prefer using Vim in a terminal. I can switch to the shell with Ctrl-Z and back with fg. However it is hard to integrate a terminal command with other GUI tools, such as editing a file in Vim from Finder.
I prefer reading my mails in the Gmail web client directly. I rarely send new mails or replies. But when I do, I want to use PGP to encrypt or sign the mail. I have tried two extensions to use PGP in Gmail, FlowCrypt and Mailvelope. But both of them are far from a competent solution for me. GPG Mail in the GPG Suite for macOS is still my preferred way. However, GPG Mail is an Apple Mail plugin, which requires downloading mails first. Based on my scenarios, I only need to download the mails I left in the inbox. But the basic setup of Gmail in Apple Mail will download many mails in the background.
I have read the post Get Everything Done & Still Have Time to Play by Jackie Ashton recently and adopted some strategies into my process. Before I plan the tasks daily by allocating them into time slots in a calendar, it is tedious and time-wasting. It messes up my agenda, which is intended only to contain the events that I must do on time. And it makes me nervous and exhausted to follow a pre-defined schedule every day. My new process is much simpler. I review my life objectives first and group them into categories. Then I evaluate their importance in my current life stage and allocate my energy in percentage into them.
