A simple Automator Action to import Screenshots in OSX into Photos:

• Select the Folder to which the Action is attached
• "Add to existing top-level album" - called "Screenshots"

I also have my Screenshots Folder on Dropbox, the Folder Actions are attached to that Folder.

find . -maxdepth 1 -name "*.jpg" -size 0

Finds and deletes all empty JPEGs at current directory:

Working with XAMPP and and phpMyAdmin makes dealing with databases more visual, but importing large db dumb files can fail/take a long time.

Importing from the command line is faster and more stable.

Use the XAMPP mysql, if there is not a global mysql

cd /Applications/XAMPP/xamppfiles/bin 

Import

./mysql -u root -p db_name < ~/path/to/db/file.sql

• Importing a ca. 300MB file takes ca. 5 seconds.
• Make sure the DB "db_name" already exists.

I've been trying to get data from an API, a async call is used to parse the data. I've be naively iterating over the responses with forEach, calling await in the forEach function, and wondering why it is not producing the result I expected, i.e. wait for the data to settle.

NG:

async function getData() {
  output = ""
  results.forEach(async (block) => {   
    var b = await abc.parse(block)
    output += b
  })
}

Solution

Use a standard for or for..of to loop over the list:

async function getData() {
  output = ""
  for (const block of results) {
    var b = await abc.parse(block)
    output += b
  }
}

Option 1

The Regenerate Thumbnails Plug-in.

Option 2

wp command line tool

Regenerate all images, without confirmation.

wp media regenerate --yes

Regenerate thumbnails only.

wp media regenerate --image_size=thumbnail

Error

Error: Error establishing a database connection.

When working on localhost, use 127.0.0.1 instead of localhost in wp.config

define( 'DB_HOST', '127.0.0.1' );

Renaming a branch on Github is straight-forward:

The "Lean More" link has some instructions how to update the local environments:

Your members will have to manually update their local environments. We'll let them know when they visit the repository, or you can share the following commands.

git branch -m oldbranchname newbranchname
git fetch origin

Username for 'https://github.com': trembl
Password for 'https://trembl@github.com': 

I tried automatically to log-in with my GitHub Password.

remote: Support for password authentication was removed on 
August 13, 2021. Please use a personal access token instead.
remote: Please see https://github.blog/2020-12-15-token-
authentication-requirements-for-git-operations/ for more information.

https://github.blog/2020-12-15-token-authentication-requirements-for-git-operations/

Get a Personal Access Token

Ok, we need a Personal Access Token instead of the password!

Go to github.com > Settings > Developer Settings > Personal access tokens, and generate a new token with full repo access.

Once we use the token instead of the password, it works.

git branch -u origin/main main
# Branch 'main' set up to track remote branch 'main' from 'origin'.

git remote set-head origin -a
# origin/HEAD set to main

Traditionally Unix systems use crontab to schedule and run repetitive jobs, OSX uses launchd, an init and operating system service management daemon.

Here is a script that call my index.php every 120 seconds. (I am download snow webcams in the index.php.)

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
  <key>Label</key>
  <string>org.trembl.snow</string>
  <key>ServiceDescription</key>
  <string>Getting Snow Pictures</string>
  <key>ProgramArguments</key>
  <array>
    <string>/Applications/XAMPP/bin/php</string>
    <string>/Applications/XAMPP/xamppfiles/htdocs/snow/index.php</string>
  </array>
  <key>RunAtLoad</key>
  <true/>
  <key>StartInterval</key>
  <integer>120</integer>
</dict>
</plist>

In Xcode, the same script looks like this:

Troubleshooting

I made a couple of errors, trying to get the script to run.

0. Permissions sudo chown <user>:staff org.trembl.snow.plist
   Incorrect permissions also cause the Load failed: 122: Path had bad ownership/permissions

1. The name of the file and the Label need to match. org.trembl.snow and org.trembl.snow.plist

2. The plist need to be placed into ~/Library/LaunchAgents.

3. If your Program has arguments, they need to be specified in an array:

   <key>ProgramArguments</key>
   <array>
   <string>/Applications/XAMPP/bin/php</string>
   <string>/Applications/XAMPP/xamppfiles/htdocs/snow/index.php</string>
   </array>

4. Both strings need to be absolute. I got this error: Load failed: 122: Path had bad ownership/permissions, which was caused by only saying index.php instead of the whole absolute path.

5. Use launchctl bootstrap and not the obsolete launchctl load.

6. Launch with sudo launchctl bootstrap gui/`id -u` ~/Library/LaunchAgents/org.trembl.snow.plist

7. Stop: sudo launchctl bootout gui/`id -u` ~/Library/LaunchAgents/org.trembl.snow.plist

Problem:

Stopping the flask server with ⌃-Z (CRTL-Z), instead of the correct ⌃-C (CRTL-C), results in the server still bound to port 5000:

OSError: [Errno 48] Address already in use

Problem: After Flask crash, the port can still be occupied.

Solution:

Check who is using port 5000

sudo lsof -i:5000

kill $PID
kill -9 $PID

Success:

[2]  + killed     flask run
