Memory Footprint of Processes

The amount of memory your system needs depends on the memory
requirements of the programs you run. Do you want to know how
to figure that out? It’s not as simple as adding up the amount of
memory used by each process individually, because some of that
memory can be shared. Read on to learn the details below.

One thing you should know about /proc/meminfo: This is not a real file. Instead /pro/meminfo is a virtual file that contains real-time, dynamic information about the system.

Build a virtual machine with VirtualBox in Linux

Virtualization is almost as old as our beloved integrated silicon chips.
At the beginning of the 1960s, there had been two major computing issues.
First, many individual mainframe models were bespoke, so incompatible.
The other stumbling block was that as integrated processors became more powerful, institutions wanted to implement flexible “timesharing” between multiple users.

VirtualBox 5.2 on Fedora

IBM dismissed this multi-user batch processing was definitely the future! But in 1963, it lost a large MIT contract to General Electric. Realising its huge mistake, IBM developed the general purpose S/360 architecture, which could be implemented on a wide range of compatible systems. In 1965, IBM released the S/360-76, the world’s first mainframe to support virtualisation. And the rest is very much history.

Do I need An antivirus in linux?

Afraid to answer a bit background knowledge is necessary first.
Viruses hardly exists any more. Programs that infect other executables, overwrite parts of them and/or add new code to them is not how malware spreads nowadays in most cases. In windows that distinction is not really necessary, windows users use the term “virus” to describe every form of malware (and user error, sorry, couldn’t resist 😉 ). But in Linux that distinction is important as virus scanners in Linux do exactly what the name says…they scan for viruses. They don’t protect you against attacks from websites in any form. And on top of that they hardly even scan for Linux viruses…there are only very few proof-of-concept Linux viruses at all. And due to people never installing anything themselves but always packages provided by the distro through the package manager there is almost no attack surface for traditional viruses…no spreading of .exe saying they are the most fancy screensaver or similar. So the Linux virus scanners actually mostly scan for windows viruses, for example in a mail server scanning email attachments before delivering the mails.

Hey you! Why don't you try Linux?!

Hi my name is Anis! And I’m a full time Linux user and I know a lot about it. It’s a great system, does not spy on you, and makes it very difficult to get malware. In the past few years, it’s also become a great platform for gaming, too. Here’s the answers to a bunch of questions I usually hear about Linux from Windows users.

Why Linux Distro's Are More Secured Than Any Other Operation Systems

Linux is an open source operating system where everyone can read the entire codes but still it is considered more secure as compared to the other operating systems. Linux has been extensively deployed in the tech market as many of the gadgets are Linux based and that is why more people are building trust on the Linux platform. To throw more light on why Linux has superior internet security capabilities, let us check out some of its security features.

Free useful software for everyone.

Free as in beer, not free as in freedom – though some of it is both. I didn’t put trialware there, or things that require you to pay, to get certain features. You can use Ninite.com to install a lot of it automatically, without any toolbars and crap like that. I didn’t include things like Blender and Sketchup, as they are, in my opinion, very niche. If you need such software, I’d assume you would already know about it. Obviously most of it is for Windows, but a lot of it is multi-platform.
