comment how does a program recognize the computer?
Registry is not the only place where traces can be left. Other options could be some hidden directories in your user folder or even communicating with cloud services storing some identifying information about your hardware.

comment Prevent rsync out of memory
See if it works better if you leave out -i. I could imagine that this is expensive over many files.

comment How to know which Certificates to leave in my browser, and which to remove
In fact, Certificate Patrol would be exactly what you want (that, plus a few weeks of use). However, it is not available for google chrome.

comment How to know which Certificates to leave in my browser, and which to remove
This is a hard problem. You can’t really know which are legit, and you don’t even know which you need and will need in the future (service providers you rely on may change the CA they use, see Certificate Patrol to get an idea on the frequency of CA switches). One of the reasons why some people in the security community consider the CA system fundamentally broken. Most people normally have to rely on mozilla (or whoever composes your certificate store, may be google in your case) to make sensible tests on the certificates they recieve applications for.

revised How to use rsync to make a copy of a huge source split into two destinations?
Make the title more informative, also, what has SSH to do with it? I also doubt that linux and unix are relevant enough. This information is included in the rsync tag (and the question would work with a cygwin-version of rsync too...)

comment Purpose of serial number in DNS zone files
Any reasonable zonefile editor will increase the serial number automagically. Also, the serial number is a useful debugging tool for the DNS admin, by comparing the number retrieved from a resolver with the number in the zonefile, the admin can rule out (or find) DNS caching as source of a problem. The zone file format depends on the DNS server though: PowerDNS e.g. natively uses SQL-based databases, while the dominant text-file format you are probably referring to is the BIND format.

comment email - Can running your own authoritative DNS server mask a dynamic IP hosted email server from being blacklisted?
Getting a static IP from a consumer ISP is no guarantee that it’ll work. Even in a datacenter you have no guarantee that the IPs routed there are “clean”.

comment email - Can running your own authoritative DNS server mask a dynamic IP hosted email server from being blacklisted?
1. These are two questions in one. Split the DNSSEC stuff off it, also I’m not sure whether thats on topic at all here. 2. What has DNS to do with your dynamic IP?

Welcome on SuperUser. This site is about general use of computer hardware and software, but the question seems to be about micro controller programming.

comment What happens if a RAM gets filled completely
@LouisMatthijssen Unless you consider the perfect conditions to be infinite RAM, linux for example will also swap on perfect conditions. On default settings, it will prefer to swap out some unused application data and instead hold more filesystem cache. This is generally desirable for servers, not so on desktops.

comment What is the virtual equivalent of physically connecting 2 NICs that are on separate devices
Think of a cable as a passive two-port hub (or switch). Then you realize why you always end up at switching guides.
