- 4Hacker News·9/22/2026researchReport claims AMD RDRAND and RDSEED never return 16-bit zero
A forum post on Hacker News alleges that AMD processors may not generate an all-zero value when using the RDRAND and RDSEED instructions at 16-bit width, while Intel systems do. The author says the behavior disappears when using 32-bit or 64-bit outputs and asks others to reproduce the result with a test application.
- 2Hacker News·9/13/2026researchWhy x86 uses ud2 for undefined instructions
The article explains the history behind x86's ud2 instruction, which is a guaranteed invalid opcode used to trigger a crash when execution reaches unreachable code. It traces how older byte sequences like 0F FF and 0F B9 were used informally before Intel standardized ud2 for consistent behavior across processors.

A GitHub project presents a native x64 port of Microsoft Word for Windows 1.1a, an early version of the classic word processor. The release highlights software preservation and reverse-engineering work to run legacy applications on modern Windows systems.
- 7Hacker News·8/8/2026researchIntel XPS 13 Matches Apple Silicon Efficiency
A benchmark comparison by Jeff Geerling suggests Dell's latest XPS 13 with Intel Core 5 320 can match or slightly exceed Apple Silicon efficiency in some tests. In the HPL Linpack benchmark, the Dell outperformed a MacBook Neo on Gflops per watt and also showed competitive idle and web-browsing power use.
- 9Hacker News·8/8/2026securityReport on Hidden Hardware Backdoors in Some x86 CPUs
A research write-up claims to demonstrate hidden hardware backdoor behavior in some x86 processors, raising concerns about CPU-level security and trust. The post has drawn significant discussion because it suggests vulnerabilities that would be difficult to detect or mitigate through software alone.

Oracle will enforce updated Always Free compute limits for Ampere A1 ARM instances starting August 18, 2026. Tenancies that exceed 2 OCPUs or 12 GB of memory in the ARM pool will have excess compute instances automatically terminated, while the two always-free x86 micro instances remain unchanged.
