I wrote about the "techie curse". Techies don't create documentation and most environments are a SOP (Standard Operating Procedures) desert. In every job in which I have started, no-one has ever given me a SOP of the services being provided. I would have to "sink or swim." Most techie managers who were treated in this manner, reinforce the behaviour by treating their subordinates in a similar manner. In reality they even go further to ridicule those who create documentation as bureaucratic. By this they imply that it is a waste of time but often the underlying reason is to be able to be a hero, as when the sh1t hits the fan, they are the only ones able to resolve it, as all the knowledge is in their heads and not on paper for anyone else to attempt to resolve. I have even been told that it stops their ability to be "business flexible." What a load of codswallop! Imagine if a new hire was given a SOP of the service they are responsible for delivering on day one of their tenure. Alas, most techies spend the first three weeks of their job being unproductive.
Firewalls are becoming increasingly important in today’s world. Hackers and automated scripts are constantly trying to invade your system and use it for Bitcoin mining, botnets or other things. To prevent these attacks, you can use a firewall on your system. IPTables is the strongest firewall in Linux because it can filter packets in the kernel before they reach the application. Using IPTables is not very easy for Linux beginners. We have created easywall - the simple IPTables web interface . The focus of the software is on easy installation and use.
