Use case: You have repository A with remote location rA, and repository B (which may or may not have remote location rB). You want to do one of two things:

• preserve all commits of both repositories, but replace everything from A with the contents of B, and use rA as your remote location
• actually combine the two repositories, as if they are two branches that you want to merge, using rA as the remote location

NB: Check out git subtree/git submodule and this Stack Overflow question before going through the steps below. This gist is just a record of how I solved this problem on my own one day.

Before starting, make sure your local and remote repositories are up-to-date with all changes you need. The following steps use the general idea of changing the remote origin and renaming the local master branch of one of the repos in order to combine the two master branches.

Goals: Add links that are reasonable and good explanations of how stuff works. No hype and no vendor content if possible. Practical first-hand accounts of models in prod eagerly sought.

A common and reliable pattern in service unit files is thus:

NoNewPrivileges=yes
PrivateTmp=yes
PrivateDevices=yes
DevicePolicy=closed
ProtectSystem=strict

Visual Studio Code allows Snippets to perform ✨Variable Transforms✨ using Regex.

Here are some common case transformations that you can apply to your snippets. In these examples, I'm using $TM_FILENAME_BASE, but the same transformations should apply to any of the Snippet Variables.

snippets-from-delimited.json can convert filenames like my-file-name, my_file_name, my file name. If your filename is delimited by a dash, underscore, or space, these should work.

snippets-from-mixed-case.json can convert filenames like myFileName and MyFileName. If your filename is in camel or Pascal case, these should work.

By default Linux distros are unoptimized in terms of I/O latency. So, here are some tips to improve that.

The performance can be checked by:

• fio --name=read --readonly --rw={read/randread} --ioengine=libaio --iodepth={jobs_per_each_worker's_command} --bs={4k/2M} --direct={0/1} --numjobs=<number_of_parallel_workers> --runtime={10/30/60} --group_reporting --filename=/dev/nvme<device> - to simulate an optimized app;
• dd_rescue /dev/nvme<device> /dev/null -b {4k/2M} {-d} - to simulate a stupid app.

Appropriate settings are changed in appropriate places, such as:

• /etc/tuned/<custom-profile>/tuned.conf:

• 重装 macOS

  • 1. 准备软件与镜像
  • 2. 制作mac的U盘启动盘
  • 3. 使用制作好的 U盘安装 macOS

• 重建软件环境

A complete gdb to lldb command map.

• Print object

(lldb) po responseObject
(lldb) po [responseObject objectForKey@"state"]

• p - Print primitive type
