Fedora plans to remove i686 (32‑bit) architecture support in two stages, ending multilib packages and ultimately stopping all i686 builds, a move that sparks controversy among developers and gamers because it threatens legacy 32‑bit games, Steam compatibility, and projects like the Bazzite gaming distro.
Fedora proposes to remove i686 (32‑bit) architecture support in upcoming releases, a move that could streamline maintenance but raises concerns among gamers and projects like Bazzite that still rely on 32‑bit libraries and Steam’s 32‑bit client.
This article reviews Linux virtual memory layouts for 32‑bit and 64‑bit systems, explains the kernel and user address spaces, details how threads consume stack memory, and outlines both virtual‑memory and kernel‑parameter limits that affect the maximum number of threads a process can create.
This article reviews Linux virtual memory layouts for 32‑bit and 64‑bit systems, explains the different memory segments, shows how the default 8 MiB thread stack impacts virtual address consumption, and calculates practical thread limits based on virtual memory and kernel parameters.
This article recounts how Ken Thompson and Dennis Ritchie devised the Unix Epoch Time as a simple integer timestamp, explains its advantages, the 32‑bit limitation leading to the Y2K38 issue, and describes the transition to 64‑bit timestamps in modern systems.
This article explains the relationship and differences among 32‑bit and 64‑bit hardware, operating systems, and applications, covering CPU families, Linux and Windows OS variants, compatibility layers, and how to identify architecture using simple commands.
The article explains the Unix epoch, how 32‑bit time counters overflow on 19 January 2038 causing the infamous 2038 bug, and why 64‑bit systems extend the range far beyond any realistic horizon, effectively eliminating the problem.
After a recent Bash upgrade on certain servers, SSH logins intermittently failed due to bash’s inability to allocate memory, prompting an investigation that revealed differences in 32‑bit and 64‑bit process memory layouts, exec‑shield behavior, and kernel mmap handling on CentOS 6.5.
