First, we set the encrypted_session_key to 'abcdefghijklmnopqrstuvwxyz123456'; Then, just in case, we disable the authorization header […]

On June 18, the release of the HestiaCP control panel for VPS/VDS servers version 1.00.0-190618 took place.

Among the advantages of our project over VestaCP, we can highlight the following: Numerous […]

This book is recommended by Alan Kay. He often says the phrase, "The computer revolution has not yet happened." But the computer revolution has begun. More accurately — it has been initiated. It was started by certain individuals, with specific values, and they had a vision, ideas, and a plan. What assumptions did the revolutionaries have when they created this plan? For what reasons? Where did they intend to lead humanity? At what stage are we […]

You will never guess. I sell factories their own programmers, and […]
