System Architecture

The BPF subsystem allows programmers to write programs that can run safely in kernel space. All memory accesses and function calls in BPF programs are statically checked for safety using the in-kernel verifier, which analyzes programs in their entirety before allowing them to be loaded. While this allows the kernel to safely run BPF programs, it heavily restricts what those programs are able to do. Among these constraints is a rule that programs cannot store pointers into BPF maps for use (such as dereferencing them or passing them to the kernel in kfunc and BPF helper invocations) at a later time. A patch set by Kumar Kartikeya Dwivedi adds this capability to BPF.

When it comes to issues like supply-chain traceability, companies like ADM are pioneering a holistic approach to business practices.

Over the last five decades or so, free and open-source software (FOSS) has gone from an almost unknown quantity available to only the most technically savvy to underpinning much of the infrastructure we rely on today. Much like software itself, FOSS is "eating the world". But that has changed—is changing—the role of the maintainers of all of that code; when "critical" infrastructure uses code from a FOSS project, suddenly, and perhaps without warning, that code itself becomes critical. But many maintainers of that software are volunteers who did not set out to become beholden to the needs of large companies and organizations when they released their code, they were just scratching their itch—now lots of others are clamoring for theirs to be scratched as well.

The Semi-Automatic Ground Environment, or SAGE, was the nation's first air defense system and was the impetus for the establishment of Lincoln Laboratory. The sections below describe the history of this seminal, large-scale system-engineering project, and the role that it had in shaping the culture of Lincoln Laboratory as it exists today.

Veteran storage analyst Fred Moore  told a Fujifilm event audience that we’re entering a zettabyte era of data storage and archival storage will be the dominant technology by capacity. The four-day Fujifilm 12th Annual Global IT Executive Summit took place in San Diego, June 22–25 and Moore, the president of Horison Information Strategies,  presented there. […]

Consultant Brad Johns thinks moving archive data from disk to a 60:40 tape:disk situation could cut its ten-year CO2 emissions by almost 60 percent and its total cost of ownership by almost half. Update: Critical point of view about tape infrastructure exclusion from tape numbers added. 12 July 2022. Johns presented his findings at the […]

Fundamentally, Open RAN is a giant step forward. It uses an open, software-driven architecture to put a generic compute layer into the special-purpose telecoms stack, which means operators will be able to automate and upgrade networks more easily, roll out new technology faster and offer the kind of services that make 5G more than just a faster mobile phone network.
