The required computing power to run IPFire depends on the area of application. Most commonly, x86 systems are being used, but ARM devices, such as Raspberry Pi or Banana Pi, are supported, too. [9] IPFire can be used in virtual environments (such as KVM, VMWare, XEN, Qemu, etc.).
Users interact with Qubes OS in much the same manner that they interact with any standard graphical desktop operating systems with some key differences: The creation of qubes (security domains) offers the means to create discrete, lean, secure application spaces by linking them to a complete root filesystem using shared templates.
OpenSSL is a software library for applications that provide secure communications over computer networks against eavesdropping, and identify the party at the other end. It is widely used by Internet servers, including the majority of HTTPS websites.
Shebang lines may include specific options that are passed to the interpreter. However, implementations vary in the parsing behavior of options; for portability, only one option should be specified without any embedded whitespace. [11] Further portability guidelines are found below.
