bouncer | A service router that uses MDNS and bouncy to do | DNS library

My understanding on express middleware has always been that it fires everytime when we put it in an express router. I was looking at the documentataion of express-bouncer npm package and I saw this:

I am using K-means clustering on a dataset with some categorical features. I have some old code that operated on non-categorical data and the sequence of doing fit, then predict works as expected.

So now I am modifying that working code to work on a dataset that has some categorical features, thus requiring one hot encoding. This is where everything goes a bit pear shaped.

It seems the predict method call is expecting the old number of columns from before one hot encoding was carried out. The dataset, after dropping the Target column has 17 columns. Then after one hot encoding it has 29 columns.

Here is my code:

I'm trying to update my Laravel version from 6 -> 8 by following this guide https://laravel.com/docs/8.x/upgrade

I'm not sure if I should update to Laravel 7 first, then to 8, never the less, I face the same composer problem when trying to update to 7.

composer update output:

After update to Xcode 12 project would no longer build.

I'm trying to generate a vector for an api import package which accepts the following arguments

I've got a function on a drop-down button which when scrolled past it, it changes position to fixed so that it's always visible. Although, my problem is when it changes to position:fixed, it's usually aligned to the right, but it changes position to the left. How can I make it so that it stays in place? I can't use any fixed "right" value, as I need this to work on mobile version as well(width of parent container varies). Check my jsFiddle https://jsfiddle.net/ramisrour/2asco9n1/6/

Also, the .dropContainer doesn't need height or width, I just set it there for the fiddle, so you can test with the scrolling.

I have a div which when clicked, height changes so that the rest of the content becomes visible. But I have a button inside this div which I would like to use as a "close-button", to change the height back to it's original value so the content is hidden again, but it's not working. Here is the code:

I am using a JavaScript library for client-side form validation (https://github.com/cferdinandi/bouncer). It works very well but has one strange behaviour that I don't understand.

I have two buttons for the form submit, each with a different value. Without validating this form using the library I will retrieve the exact value on server-side. But when I use the library for validation the value will disappear. All other form values are available. I checked the whole library code and found out that "event.preventDefault()" seems to be the problem.

When I remove this line everything is fine but of course, form validation won't work.

Someone has any idea?

my problem is that i don't have an idea on how to properly initialize an array containing blocks to drawn on a small matrix display. Initializing the first object works sometimes (block) but going through the for-loop to initialize remaining objects doesn't seem to do anything. I would be very glad for any help!
