Andrew S. Tanenbaum Receives ACM Software System Award

Impact of the textbooks

  • Many commenters learned operating systems, networking, and computer architecture from these books in the 80s–2000s.
  • Texts are described as unusually clear, approachable, and even “thriller-like,” yet dense and rigorous.
  • Several anecdotes: failing students turning grades around by switching to these books; people still keeping them on shelves decades later; some used them later as instructors.
  • “Structured Computer Organization,” “Operating Systems: Design and Implementation,” “Modern Operating Systems,” and “Computer Networks” are cited most.

MINIX: role, licensing, and Intel ME

  • MINIX is praised as an elegant microkernel that influenced Linux and educated many, but never became the dominant free Unix-like system.
  • Multiple comments dwell on the “what if” of MINIX having a FLOSS license earlier; some think it could have occupied Linux’s historical role.
  • Discussion notes MINIX’s use inside Intel Management Engine, making it one of the most widely deployed OSes—though some are uneasy about this “hidden” role.
  • Intel allegedly chose it partly for its BSD-style license and built-in services; alternative microkernels (L4, seL4) are mentioned but seen as less suitable or license-constrained.

MINIX3’s decline

  • Consensus that MINIX3 development has effectively stalled; no commits in years and an unreleased 3.3.0 despite fixes.
  • Contributors describe technical debt: 32‑bit, uniprocessor kernel, aging hardware support, heavy dependency on NetBSD source tree.
  • Capabilities like fault-tolerant drivers and live-updatable services are praised as impressive research outcomes.

Microkernels vs monolithic kernels

  • The old Tanenbaum–Torvalds debate is referenced, especially over microkernel vs monolithic designs.
  • Some note that Linux was initially developed on MINIX and that criticism may have helped shape Linux; others point to modern performant microkernels as partial vindication.

Distributed OSes and systems research

  • Several commenters lament that mainstream systems don’t provide a unified distributed OS where processes migrate seamlessly across personal devices.
  • Others argue this is niche or “cool but not essential,” preferring higher-level, multi-system tools or cloud abstractions.
  • Counterpoint: distributed OS research is still active; ideas appear in clouds, VM/container live migration, and academic microkernel projects.
  • Debate becomes heated over whether an OS “should” provide transparent distributed access to resources; no consensus, but strong opinions on both sides.

Electoral-vote.com and broader influence

  • Multiple comments highlight the long-running election analysis site run by Tanenbaum, now co-written, as a clear, data-driven daily political summary.
  • Some credit his networking book and even a famous “sneakernet” quote with influencing thinking in industry (e.g., about Netflix’s early strategy).

Recognition and comparisons

  • Many express that this award feels overdue given his influence on generations of students and practitioners.
  • A few wonder why Linux’s creator hasn’t received the same ACM award; possible reasons (including personality) are speculated but unresolved.
