This warning is pretty self- explanatory:

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@         WARNING: UNPROTECTED PRIVATE KEY FILE!          @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
Permissions 0644 for '/Users/georg/.ssh/my_rsa_key' are too open.
It is required that your private key files are NOT accessible by others.
This private key will be ignored.

Solution

Limit the key to read/write access by the user only:

chmod 600 ~/.ssh/my_rsa_key

It's also possible to make it only readable by the user, but then you need to chmod every time you want to update/change it.

chmod 400 ~/.ssh/my_rsa_key

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.

Problem: IIJMIO Network not working: Solution: Dowload and Install Profile

1. Go to https://t.iijmio.jp/en/apn/
2. Download and Install the Profile
3. That's it.

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 on Local Server

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

Import with specified Server

mysql -u username -p -h hostname db_name  < ~/path/to/db/file.sql

Checking Status of MySQL Server

mysqladmin -u username -p -h hostname status

• -p asks for the password on execution
• Importing a ca. 300MB file takes ca. 5 seconds.
• Make sure the DB "db_name" already exists.

Troubleshooting

I exported all the DB from one installatino as one, big localhost.sql and then tried to import it in another one. That creates the following error:

ERROR 2006 (HY000) at line 127571: MySQL server has gone away

Some DBs have been imported, but not all.

Workaround: Export/Import DBs individually.

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: Plugin

The Regenerate Thumbnails Plug-in.

This option is usualy slower - and some hosting providers might confuse it for a malicious attach and block the IP.

Option 2: WP-CLI

WP-CLI is the command line interface for WordPress/ClassicPress.

Installation

From the WP-CLI Guide

curl -O https://raw.githubusercontent.com/wp-cli/builds/gh-pages/phar/wp-cli.phar

Run --info from your WP root directory, to check if it works:

php wp-cli.phar --info

If you get a json_encode error, it means your PHP version is not compatible with WP-CLI.

PHP 7 was the default on one server, it did not work.

Check for other PHP versions

which php
// /usr/bin/php

ls /usr/bin/php* 
// php80 php81 php82 php83

Let's use the latest verson of PHP.

php83 wp-cli.phar --info

Regenerating

Regenerate all images, without confirmation.

php83 wp-cli.phar media regenerate --yes

Regenerate thumbnails only.

$ php83 wp-cli.phar media regenerate --image_size=thumbnail

More options for regenerating images with WP-CLI:

# Regenerate thumbnails for given attachment IDs.
php83 wp-cli.phar media regenerate 123 124 125

# Re-generate all thumbnails that have IDs between 100 and 200.
seq 100 200 | xargs php83 wp-cli.phar media regenerate

# Re-generate all thumbnails that have IDs between 100 and 200.
seq 100 200 | xargs php83 wp-cli.phar media regenerate

# Re-generate all thumbnails that have IDs between 100 and 200, only thumbnails
seq 100 200 | xargs php83 wp-cli.phar 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
```php
define( 'DB_HOST', '127.0.0.1' );
