Colorful JSON in HTML

JSON can very easily be translated into JavaScript. JavaScript can be used to make HTML in your web pages.

Edit — best to first try:

mariadb-secure-installation -u $(whoami)

Original version here below in case the above does not work for you.

Backblaze's bztransmit process loads a file called bzfileids.dat into RAM. This file is a list of all files Backblaze has previously uploaded, including a unique identifier for each file. On most systems, this files is under 100MB in size (paraphrased from Backblaze support rep Zack).

Mine had grown to 6GB. This means that anytime bztransmit runs, it will load this 6GB file into RAM while it is backing up. In doing so it was purging massive ammounts of memory causing behavior like Chrome (usign 10GB of memory on it's own) to hang/beachball for 30 seconds and then refresh all it's windows.

There is no way to alter this behavior once it's begun, aside from starting over with some files excluded. The index needs to be rebuilt from scratch without the excessibe file count, that also means you can't restart and "inherit" a previous backup.

In my case the biggest culprits were .git and node_modules, so I excluded those, started a new backup (transfered licnese) and spent a week hunting for fast internet I could

Exclude node_modules and .git from Backblaze backups on Mac

Edit the file at /Library/Backblaze.bzpkg/bzdata/bzexcluderules_editable.xml.
Add these rules inside the bzexclusions tag:

<!-- Exclude node_modules. -->
<excludefname_rule plat="mac" osVers="*"  ruleIsOptional="t" skipFirstCharThenStartsWith="users/" contains_1="/node_modules/" contains_2="*" doesNotContain="*" endsWith="*" hasFileExtension="*" />
<excludefname_rule plat="mac" osVers="*"  ruleIsOptional="t" skipFirstCharThenStartsWith="users/" contains_1="/.git/" contains_2="*" doesNotContain="*" endsWith="*" hasFileExtension="*" />

You can replace "*.DS_Store" with any other recurrent file (e.g. Desktop.ini)

Please!

Validate that you are going to delete only what you want passing the --dryrun option. I've left if by default just in case of copy/paste.

aws s3 rm s3://your.bucket.name/maybe-a-subkey --dryrun --recursive --exclude "*" --include "*.DS_Store"

jq: JSONL ↔︎ JSON conversion

Prerequisites

jq — https://jqlang.org/ — "like sed for JSON data"

There are several options available for installing jq. I prefer to use Homebrew: brew install jq
JSONL → JSON
