September blog https://www.9ywk.com/ zh-CN "September blog" was established on September 15, 2016 (named September) website: www.9ywk This month, non-profit website. Most of them record life, personal feelings and some technical abstracts, or reprint and share some interesting things. Sat, 02 Apr 2022 17:40:00 +0800 Sat, 02 Apr 2022 17:40:00 +0800 Windows screen stroboscopic solution https://www.9ywk.com/384.html https://www.9ywk.com/384.html Sat, 02 Apr 2022 17:40:00 +0800 September The old laptop on my hand has been used for many years. My eyes are very tired after using it for a while. I don't pay much attention to this detail problem. Today, I'm bored to open the camera to check the flicker problem on the screen. I'm scared when I see it. Stroboscopic is very serious and it's too harmful to the eyes!!!

 It's too flashy

{alert type="success"}
Mobile camera professional mode, adjust ISO to the maximum, and you can view it by aiming at the screen
{/alert}

View default strobe

So I searched the Internet and found a software to change the strobe. The default stroboscope was only 200

 Test

CMD window execution software: PWMHelper. exe View default strobe

Change the strobe to 2000

 Test

CMD window execution software: PWMHelper. exe 2000 Change the strobe to 2000

{message type = "info" content = it is suggested to modify it appropriately. It may affect the screen hardware if it is too large. "/}

After modification, the stripe will not flash in an instant

 Test

Automatic modification after startup

After testing, it was rebooted and restored.
Bat script is used to realize automatic modification after startup.

1. Create a new script with bat suffix

 @echo off start  "wumin" "C:\Windows\System32\cmd.exe" C:\Users\jiuyue\Desktop\CMD\PWMHelper. exe 2000 taskkill /f /im cmd. exe exit

{collapse}
{collapse item label = above script command explain click expand "}
The first batch is executed on the command line.

The second line is the start command, which starts CMD Exe program. As for Wumin, the name of the commander of the CMD command can be left blank. The following is the storage path of the CMD.

The third line is the command to execute in CMD.

The fourth line is to close the CMD command window after executing the command.

The fifth line is also an exit command, which seems to be optional.
{/collapse-item}
{/collapse}

2. Put this script into

 C:\ProgramData\Microsoft\Windows\Start Menu\Programs\StartUp

The system can start automatically and execute command modification. If you cannot find the above directory, you can find it through "run" – shell: startup.

statement

The method of swiping the machine and all the documents of this project are not developed or made by myself. I have only done resource integration. All the documents are obtained from the Internet and have been uploaded to Alibaba's online disk. You can only learn and exchange, and do not do business transactions. The economic disputes and legal liabilities arising from this have nothing to do with me.

As well as the risks of unlocking the mobile phone, I hope you all know. Therefore, the way to unlock the mobile phone should be consulted by Baidu or Xiaomi community. This is a tutorial. If the software and hardware damage after unlocking and brushing is irrelevant to me, it is recommended not to use the main machine to try! The person watching the video or downloading the file on the network disk agrees with this statement by default.

The default listening port of SSH is 22. If you do not specify other ports by force, "port 22" notes that all ports are open 22 access ports. I reserved port 22 above to prevent access to port 22 due to various permissions and configuration problems. When everything is OK, close port 22.

Local projects are uploaded to GitHub via GIT https://www.9ywk.com/354.html https://www.9ywk.com/354.html Fri, 02 Apr 2021 16:14:00 +0800 September Download git installation
Install it by default, and then open the menu bar git bash

First installation configuration

 #Configure mailbox with the same account name git config --global user. name “Your_github-Username” git config --global user. email “Your_github-email” #View user name mailbox git config user. name git config user. email #You can also view the user's mailbox directly vim ~/. gitconfig Exit: Q

Create SSH key
Since the transmission between the local git warehouse and GitHub warehouse is encrypted through SSH, you need to set it up when connecting

First look at your C disk user directory has SSH directory Hidden (user name)
Have a look at it Does SSH have any Private key ID_ RSA and public key ID_ rsa. pub These two files, if any, will jump to the next step. If not, they will be created by the following command

 ssh-keygen -t rsa -C "your_github-email"

Just go back a few times

GitHub setting SSH key
Login to GitHub New SSH key

title content
Title Fill in as you like, for example, GIT
Key Generated: ID_ rsa. pub

Create empty warehouse (for uploading)
https://github.com/new

Other orders

git rm -r --cached .
Delete all files in the cache (note that if there is a space, if you change. To a file name, you will cancel a file)

Git upload

The remote warehouse is empty

(new warehouse, no readme. MD)

1. CD to the directory to be uploaded (local warehouse)
For example, in the test folder, PWD can view the current location

2. Initialize the local warehouse

 git init

The current test directory will create Git folder
This means making this folder a git manageable repository, a local repository that git uses to track and manage version libraries

3. Associate remote warehouse

 Git remote add origin GitHub warehouse HTTPS address

4. Add file to cache

 git add .        // All contents in the current directory / / add user or git file Git status / / view cache file

Pay attention to this ".", There is a space in it On behalf of this test, all the files in this folder are submitted. You can also submit the specified file by git add

5. Submission instructions

 git commit -m 'first commit'

-The quotation mark after M is the comment content submitted this time. If it is not filled in, an error will be reported

6. Upload

branch

 Git branch XXX / / create branch Git branch - A / / view branch Git checkout XXX / / switch branches
 git push -u origin master

The remote warehouse is empty, so the parameter - u should be added to push the cached file to the master branch of GitHub warehouse

Remote warehouse is not empty

(old warehouses, including those without records)

1. Clone remote warehouse (download)

 Git clone warehouse address

2. CD to clone repository
➽ the cloned repository contains No longer need to associate git with GIT

3. Add file to cache

 git add .        // All contents in the current directory Git add user / / specify a file or folder Git status / / view cache file

4. Submission instructions

 git commit -m 'first commit'

5. Upload

 git push origin master

Delete warehouse file

Local and remote deletion

 Git clone warehouse address //There is something to ignore Git RM file / / will be deleted locally Git RM - R folder / / will be deleted locally git rm -rf .               // Local all will be deleted Git commit - M 'delete a file' git push origin master

If you do not want to delete the local file, only delete the corresponding part of the cache, add --cached

Remote warehouse delete only

 Git clone warehouse address //There is something to ignore Git RM -- cached file / / will not be deleted locally Git RM - R -- cached folder / / will not be deleted locally git rm -rf --cached .            // All local files will not be deleted Git commit - M 'delete a file' git push origin master
