Detecting a Credit Card number in a field using JavaScript

Given a field such as <input id="notes" type="text" names="notes"> You can detect a Credit Card number using the following in jQuery. This will detect 15 or 16 digit credit card numbers because of the d{3,4}. To only detect 15 or 16 change that to be only d{3} for 15 or d{4} for 16.

$('#notes').on('input', function() {
    const ccDetected = $('#notes').val().match(/\b(?:\d{4}[ -]?){3}(?=\d{3,4}\b)/gm);
    if (ccDetected) {
        alert('don''t use credit cards!');

SurveyMonkey CX API call

SurveyMonkey has a great new API available that allows you to easily send someone an email programmatically. I ran into some hiccups while setting it up and there’s almost zero documentation out there.

Endpoint: This is provided at the end of setting up a survey. Should look like${fromSurvey}/replies


name="Content-Type" value="application/json"
name="Authorization" value="Token token=#apiToken#"


    "person": {
        "email": "emailAddress",
        "first_name": "first name",
        "last_name": "last name",
        "fields": {
            "Custom Field": ["custom field value"]
    "delay": 0

The custom fields must match exactly what you put in your admin and you must pass it in as a list. If you don’t pass a list it won’t register. The delay is the number of days to delay sending the survey.

My full postman request is below with sensitive information redacted.

Updating all sub modules in a git project

This command will find all the submodules in your current git projects and pull down changes from master for each submodule.

git submodule -q foreach git pull -q origin master

Once you pull down changes make sure you push the changes back to your project to see the changes.

What is this actually doing?

git submodule basically gets all the submodules in your project

-q means quiet which means it doesn’t output the name of the submodule as it loops through them. This parameter is not required.

foreach um, it loops through each submodule

git pull -q origin master this pulls down the changes from master on the submodule and doesn’t output the changes. Again, the -q is not required, but will reduce the conole output.

Bash loop through folders recursively and lower case files

This script will loop through all files and folders recursively and make them lower case. Please do not just blindly run this against your intended directory. The echo is there for testing and once you know that works then use the mv command

You can perform any command you’d like after the tr. In my case it’s replace all upper case letters with lower case ones.

If you don’t include the if statement, you’ll get a warning message if it tries to rename to the same case, so that keeps the console clean.

find /home/buschm3/bananas -depth -name '*' -print0 |
while IFS= read -r -d '' src; do
    dst=`dirname "${src}"`/`basename "${src}" | tr '[A-Z]' '[a-z]'`
    echo "$src"
    echo "$dst"
    if [ "${src}" != "${dst}" ]
        #mv "$src" "$dst"
