Brazil Federal republic in South America

Brazil, officially the Federative Republic of Brazil, is the largest country in both South America and Latin America. At 8.5 million square kilometers and with over 208 million people, Brazil is the world's fifth-largest country by area and the fifth most populous. Brazil borders every South American country except Chile and Ecuador. Its capital is Brasília, and its most populated city is São Paulo. The federation is composed of the union of the 26 states, the Federal District, and the 5,570 municipalities. It is the largest country to have Portuguese as an official language and the only one in the Americas; it is also one of the most multicultural and ethnically diverse nations, due to over a century of mass immigration from around the world.

Linux kernel operating system kernel

The Linux kernel is a free and open-source, monolithic, Unix-like operating system kernel. The Linux family of operating systems is based on this kernel and deployed on both traditional computer systems such as personal computers and servers, usually in the form of Linux distributions, and on various embedded devices such as routers, wireless access points, PBXes, set-top boxes, FTA receivers, smart TVs, PVRs, and NAS appliances. The Android operating system for tablet computers, smartphones, and smartwatches uses services provided by the Linux kernel to implement its functionality. While the adoption on desktop computers is low, Linux-based operating systems dominate nearly every other segment of computing, from mobile devices to mainframes. As of November 2017, all of the world's 500 most powerful supercomputers run Linux.

Work

De Melo was one of the key founders of Conectiva which later became part of Mandriva.

Conectiva was a company founded on August 28, 1995, in Curitiba, Paraná, Brazil, by a group of friends, among them Arnaldo Carvalho de Melo, who was a pioneer in the distribution of Linux and open source software in Brazilian Portuguese, Spanish and English for all of Latin America. Besides a customized Linux distribution for the Latin American market, Conectiva developed a series of products and additional services directed to meet the market demand for open source tools, including books, manuals, additional software like Linux Tools and embedded systems, OEM programs, applications port, training kits and the "Revista do Linux" Linux magazine. In addition, the company provided consulting services, training and technical support in all of Latin America through its own service centers and certified partners.

Mandriva S.A. was a public software company specializing in Linux and open-source software. Its corporate headquarters was in Paris, and it had development centers in Metz, France and Curitiba, Brazil. Mandriva, S.A. was the developer and maintainer of a Linux distribution called Mandriva Linux, as well as various enterprise software products. Mandriva is a founding member of the Desktop Linux Consortium.

The Linux kernel mailing list (LKML) is the main electronic mailing list for Linux kernel development, where the majority of the announcements, discussions, debates, and flame wars over the kernel take place. Many other mailing lists exist to discuss the different subsystems and ports of the Linux kernel, but LKML is the principal communication channel among Linux kernel developers. It is a very high-volume list, usually receiving about 1,000 messages each day, most of which are kernel code patches.

kGraft is a feature of the Linux kernel that implements live patching of a running kernel, which allows kernel patches to be applied while the kernel is still running. By avoiding the need for rebooting the system with a new kernel that contains the desired patches, kGraft aims to maximize the system uptime and availability. At the same time, kGraft allows kernel-related security updates to be applied without deferring them to scheduled downtimes. Internally, kGraft allows entire functions in a running kernel to be replaced with their patched versions, doing that safely by selectively using original versions of functions to ensure per-process consistency while the live patching is performed.
