Searching for Files

Find images in a directory that don't have a DateTimeOriginal

exiftool -filename -filemodifydate -createdate -r -if '(not $datetimeoriginal) and $filetype eq "JPEG"' .

###Output photos that don't have datetimeoriginal to a CSV### Note this can take a long time if you have a lot of jpgs

This is one chapter of my "Chrome Extension Workshops" tutorial, see the rest here: https://gist.github.com/caseywatts/8eec8ff974dee9f3b247

Making Bookmarklets

I'm feeling very clever. I've got this sweet line of javascript that replaces "cloud" with "butt". My mom would LOVE this, but she doesn't computer very well. I'm afraid to show her the Developer Console and have her type/paste this in. But she IS pretty good at bookmarks, she knows just how to click those!

A bookmark normally takes you to a new web page. A bookmarklet is a bookmark that runs javascript on the current page instead of taking you to a new page. To declare that it is a bookmarklet, the "location" it points to starts with javascript:.

Using Git to Manage a Live Web Site

Overview

As a freelancer, I build a lot of web sites. That's a lot of code changes to track. Thankfully, a Git-enabled workflow with proper branching makes short work of project tracking. I can easily see development features in branches as well as a snapshot of the sites' production code. A nice addition to that workflow is that ability to use Git to push updates to any of the various sites I work on while committing changes.

1. Using BoilerPy3, a native Python port of Christian Kohlschütter's Boilerpipe for automatically extracting main textual content of a webpage based on shallow text features. It gives us the page title and it's contents

!pip install boilerpy3
from boilerpy3 import extractors

extractor = extractors.CanolaExtractor()

doc = extractor.get_doc_from_url('https://www.newsrain.in/petrol-diesel-prices/Odisha')
page_title = doc.title

rclone systemd service

Preparation

This service will use the same remote name you specified when using rclone config create. If you haven't done that yet, do so now.

Next, create the mountpoint for your remote. The service uses the location ~/mnt/<remote> by default.

mkdir ~/mnt/dropbox

	'use strict';

	const findFirstOccurrence = (string, searchElements, fromIndex = 0) => {
	let min = string.length;
	for (let i = 0; i < searchElements.length; i += 1) {
	const occ = string.indexOf(searchElements[i], fromIndex);
	if (occ !== -1 && occ < min) {
	min = occ;
	}
	}

	Convert YouTube subtitles(vtt) to human readable text.

	Download only subtitles from YouTube with youtube-dl:
	youtube-dl --skip-download --convert-subs vtt <video_url>

	Note that default subtitle format provided by YouTube is ass, which is hard
	to process with simple regex. Luckily youtube-dl can convert ass to vtt, which
	is easier to process.
