How to install a WordPress plugin from a Gist

How to setup a practically free CDN using Backblaze B2 and Cloudflare

⚠️ Note 2023-01-21
Some things have changed since I originally wrote this in 2016. I have updated a few minor details, and the advice is still broadly the same, but there are some new Cloudflare features you can (and should) take advantage of. In particular, pay attention to Trevor Stevens' comment here from 22 January 2022, and Matt Stenson's useful caching advice. In addition, Backblaze, with whom Cloudflare are a Bandwidth Alliance partner, have published their own guide detailing how to use Cloudflare's Web Workers to cache content from B2 private buckets. That is worth reading,

Upload Files to Google Drive using Javascript

Upload Files to Google Drive using Javascript

News

At October 11, 2019, I published a Javascript library to to run the resumable upload for Google Drive. When this is used, the large file can be uploaded. You can also use this js library.

Description

This is a sample script for uploading files to Google Drive using Javascript. The files are uploaded by Drive API v3. gapi.client.drive.files.create() can create an empty file on Google Drive. But it cannot directly upload files including contents. I think that this might not be able to upload files and metadata with the multipart/related, although this might be resolved by the future update. So now, as one of workarounds, I use using XMLHttpRequest.

  • This sample uses gapi.
  • Before you use this, please enable Drive API at API console and carr
