Python, Selenium for custom browser automation scraper

With 365SMS service you can receive SMS to a virtual number and verify your accounts on Facebook, Instagram, Twitter, Amazon, Airbnb, etc.

  • Buying virtual numbers and receiving SMS in automatic mode.
  • A virtual phone number is issued for 20 minutes. During this time, you can receive an unlimited number of SMS absolutely free.

  • Large selection of services (incl. Linkedin) and countries for SMS activation.
  • Convenient API for comfortable work with external software.
  • User-friendly interface. Search by country and service makes it easy to buy a virtual phone number.
  • Dicounts for numbers in bulk.

Note

Since the virtual number is not in the country it represents, so a created 3d party account might be blocked. Therefore it’s better to:

1. Use mobile proxies that match the geolocation of the region of the purchased virtual number;
2. Use a mobile user agent.

Often the problem is not in the number, but in the wrong registration method.

AI code-writing assistant that understands data content and generates code

Recently I’ve encountred a client that predicts “in 6 month AI will be able to do much coding instead of man”.

…in years you’ll be able to on the fly, ask the AI to purchase a server, or create a website with X website builder… and basically, I bet it will write code on the fly on your demand where it connects to these tool’s APIs to really make things happen. It could do this now for some easy stuff but it’s unreliable and will mess up.

Now we’ve ancountered a interesing public repo, called Sketch. It’s AI code-writing assistant for Pandas (Python) users.
