Git

What are the best practices for naming git branches?

1. 使用前缀结构

使用前缀来表示分支的类型和用途，这样可以更直观地了解分支的目的。常见的前缀包括：

Tips on Profile

先说几个小坑点：

默认情况下，Golang Profile 取样的频率为 100Hz，意味着每 10ms 才会取样一次，所以程序运行时间少于 10ms 肯定不会被取样

A Quick Note

学习 Vim 最好的方法就是渐进式学习，一开始只用那些最基础的操作，当你有一天突然觉得某种操作不够方便，觉得应该存在一种更高效的操作时，就上网去搜，并学习相关知识！

How to do jjjjjjjjjjjjjjj or kkkkkkkkk more effectively？

1. Use Ctrl-d and Ctrl-u These commands allow you to scroll through the buffer more quickly:

• Ctrl-d: Scroll down by half a page.
• Ctrl-u: Scroll up by half a page.

2. Use Ctrl-f and Ctrl-b For full-page scrolling:

• Ctrl-f: Scroll down by a full page.(forward)
• Ctrl-b: Scroll up by a full page.(backward)

Job Control

Signals can do other things beyond killing a process. For instance, SIGSTOP pauses a process. In the terminal, typing Ctrl-Z will prompt the shell to send a SIGTSTP signal, short for Terminal Stop.

# journalctl run remotely, grep run locally
ssh myserver journalctl | grep sshd
# both commands run remotely
ssh myserver "journalctl | grep sshd"

sed

sed (Stream Editor) is a powerful command-line tool in Unix/Linux that is used for parsing and transforming text, typically used for finding, replacing, or deleting content in a file or input stream.

Shell Tools and Scripting

Shell Scripting

To assign variables in bash, use the syntax foo=bar and access the value of the variable with $foo.

The shell

How does the shell know how to find the date or echo programs?

Non-Repeatable Read

A non-repeatable read occurs, when during the course of a transaction, a row is retrieved twice and the values within the row differ between reads.

Designing a TPS for clouds will meet these challenges:

• Diverse functionality.
  • The concept of translytics as “a unified and integrated data platform that supports multi-workloads such as transactional, operational, and analytical simultaneously in realtime, … and ensures full transactional integrity and data consistency”.
• Scale
  • Cloud-first data platforms are designed to scale well beyond the limits of a single application.
• Latency
  • With the thrust into new interactive domains like social networks, messaging and algorithmic trading,latency becomes essential.
• Multi-tenancy
  • Maintaining access rights is therefore an important design consideration for TPSs.
