Website Archiving

Recently, I was deeply immersed in the topic of archiving websites. I was asked by friends who were afraid of losing control over their work on the Internet due to poor system administration or hostile deletion. Such threats make website archiving an essential tool for any sysadmin. As it turned out, some sites are much more difficult to archive than others. This article demonstrates the process of archiving traditional websites and shows how it does not work on trendy one-page applications that inflate the modern web. 3r3202.

For 20 years or so, there has been a discussion about whether to use www in the canonical hostname (CNAME) of your website. So, use or not?
 
 
To be or not to be Whether to use www on your domain?  
 
Although many use the terms “domain name” and “host name” interchangeably, there is a difference between them, and it’s not just the semantics. I will simplify this description a bit to concentrate on the point.

Monitoring Windows servers on pure MS SQL, and how I secretly implemented this

Once, in a galaxy far far away, there was a firm that had long since grown from a startup, but which still remained fairly compact and efficient. The company hosted (on its hardware) hundreds of Windows-servers, and it had to be monitored. Even before I came to it, the NetIQ system was chosen as the solution. 3r3116.  3r3124. 3r3116.  3r3124. I was instructed to set up NetIQ, and the one who did it before me did not say a single word about it. Printed I soon realized why.
