Youtube API get thumbnail image
Each YouTube video has 4 generated images. They are predictably formatted as follows:
http://img.youtube.com/vi/<insert-youtube-video-id-here>/0.jpg
http://img.youtube.com/vi/<insert-youtube-video-id-here>/1.jpg
http://img.youtube.com/vi/<insert-youtube-video-id-here>/2.jpg
http://img.youtube.com/vi/<insert-youtube-video-id-here>/3.jpg
The first one in the list is a full size image and others are thumbnail images. The default thumbnail image (ie. one of 1.jpg, 2.jpg, 3.jpg) is:
http://img.youtube.com/vi/<insert-youtube-video-id-here>/default.jpg
For the high quality version of the thumbnail use a url similar to this:

How to create an HTTPS certificate for localhost domains

How to create an HTTPS certificate for localhost domains

This focuses on generating the certificates for loading local virtual hosts hosted on your computer, for development only.

Do not use self-signed certificates in production ! For online certificates, use Let's Encrypt instead (tutorial).

fix: Nginx: stat() failed (13: permission denied)

Nginx: stat() failed (13: permission denied)

from https://stackoverflow.com/questions/25774999/nginx-stat-failed-13-permission-denied

Nginx operates within the directory, so if you can't cd to that directory from the nginx user then it will fail (as does the stat command in your log). Make sure the www-user can cd all the way to the /username/test/static. You can confirm that the stat will fail or succeed by running

sudo -u www-data stat /username/test/static

Iterate over decoded PDF page content with Python

Introduction

This note shows how to iteratively retrieve the decoded content of the pages in a PDF file using Python and the pdfminer Python package.

At the time of writing, the latest version of pdfminer was used, i.e., 20140328. Thus, as the package seems poorly maintained and prone to API-breaking changes one may have to explicitly install this version for the following code to work.

Code

The following generator will iterate over a PDF file under a given filename and iteratively yield the text content of each PDF page:
