To automatically calculate distance between a camera and target locator.

1. Create > Measure Tools > distance Tool. Select center of camera and where the target locator will be
2. Since render with Arnold, it need to connect to CameraShape1 + Arnold Focus Distance. NOTE: It’s Not Maya default [Depth of Field > Focus Distance]
3. MEL Command line is

connectAttr -f distanceDimension1.distance cameraShape1.aiFocusDistance;

Now as you move either the target or camera, automatically calculate the focus distance for DOF! Just adjust Aperture Size.

for migrating Ubuntu22, php8.1, I’ve updated my blog (wordpress) too.

1. Simply download the latest WordPress (6.3.1) and place in a server designated area (ie. /var/www/wordpress) and chown www-data:www-data -R /var/www/wordpress
2. in the mysql database, create a database named ‘wordpress‘
3. adjust php-fpm and nginx max_upload_file_size, if you want to upload .sql file using phpmyadmin. then create a database named ‘wordpress-yourdata‘
4. import the SQL file, so all the previous data is migrated.
5. go to ‘wordpress’ folder, edit ‘wp-config.php‘
6. create nginx conf file for the blog (ie. blog.koodesignstudio.com.conf)
7. restart nginx (dont’ forget “sudo nginx -t“
8. certbot to the blog.koodesignstudio.com
9. access with a browser
10. initial configuration for the new wordpress
11. start from a brand new plain wordpress,
12. update ‘wp-config.php‘ database to ‘wordpress-yourdata‘, now all the data is coming from the previous database
13. copy images from the previous wordpress ./wordpress/wp-content/uploads
14. install the theme and plug-ins as same as the previous
15. done!

!IMPORTANT even to migrate from another server, frist create a default ‘wordpress’ dabase, then change ‘wp-config.php’

owncloud stop supporting php8. So I decided to move on to next. nextcloud!

I’ve been upgrading ubuntu18 to 22. It’s a pretty big jump, so many major upgrade required. And since owncloud I’ve been using no longer support PHP8, so decided to search alternative.

This is great how-to article: https://www.linuxbabe.com/ubuntu/install-nextcloud-ubuntu-22-04-nginx-postgresql

basically follow the instruction above and good to go except I use mysql instead.

I’ve already installed phpMyAdmin so I use to create a database for nextcloud (as ‘nextcloud’) and be able to use with my account, not root. then change the entire nextcloud folder to sudo chown www-data:www-data

run certbot to make ssl enable.

then access to the nextcloud, using the GUI to set up my account.

then download the desktop app to my mac, install, configure to sync the cloud folder <> mac local.

the sync speed is pretty fast. I’m impressed but it’s been more than 7 years I’ve used the owncloud, it’s good to be updated.

This is for vue 2

First: install ‘vue-gtag’ . this should be Ver 1. And it works with GA4 too.

IMPORTANT: add @legacy

npm install vue-gtag@legacy

Second: Update main.js

NOTE: use “vue-router” to automatically log “pages”

import Vue from "vue";
import App from "./App.vue";
import router from "./router";

// vue-gtag
import VueGtag from 'vue-gtag'
Vue.use(VueGtag, {
  config: {
    id: 'G-xxxxxxxxx'
  }
}, router)

new Vue({
  router,
  render: (h) => h(App),
}).$mount("#app");

DONE!
