- Aug 13, 2026 Bump Allocation and the Cost of Arena Reset Why a pointer-increment allocator can serve thousands of requests in a few cycles, what alignment bookkeeping it still needs, and the ownership rule that makes wholesale reset safe. memory systems
- Jul 6, 2026 Attention as Content-Based Alignment Over Encoder States How a decoder selects among stored states with a learned weight distribution, why that gives a short gradient path to any position, and what the attention weights cannot represent. deep learning
- Jul 2, 2026 Alignment, Overflow, and Scroll Containers How alignment distributes free space inside a box, what overflow values do to the box model, and why one axis cannot stay visible when the other scrolls. web platform
- Apr 15, 2026 Word Size, Endianness, and Structure Layout Across Architectures Why the same C source produces different bytes on a 32-bit and a 64-bit build, how endianness changes on-disk and on-wire structures, and where alignment padding hides. operating systems
- Mar 13, 2026 Alignment and Uniformity as Separate Objectives Contrastive losses can be decomposed into a term that pulls positive pairs together and a term that spreads all representations apart, and the two terms trade against each other in measurable ways. deep learning
- Feb 5, 2026 Connectionist Temporal Classification and Monotonic Alignment How a blank symbol and a collapse rule turn frame-by-frame predictions into a sequence probability, why the sum over alignments needs a lattice recursion, and what the independence assumption costs. deep learning
- Jan 29, 2026 Struct Padding and the Alignment Rule Behind sizeof How alignment requirements, member order, and trailing padding determine a structure size, and why reordering members can shrink it without changing any field. systems programming
- Nov 20, 2025 Logical Block Size, Read-Modify-Write, and Misaligned I/O Why a device with 4 KiB pages can still accept 512-byte sectors, what that emulation costs internally, and how alignment and atomicity guarantees interact. filesystems
- Jul 4, 2025 Alignment, Padding, and Over-Aligned Allocation What the alignment guarantee on a returned pointer actually promises, how allocators satisfy requests stronger than the ABI default, and why page-granular requests behave differently. memory systems
- Nov 22, 2024 Alignment, O_DIRECT, and the Cost of Bypassing the Page Cache The alignment and size rules a direct I/O request must satisfy, which part of the page-cache path disappears and which remains, and the cases where the bypass loses rather than wins. performance engineering
- Aug 3, 2024 Struct Passing and Register Classification Across ABIs How a compiler decides whether a struct travels in registers or in memory, what the eightbyte classification rules encode, and where layouts diverge between C and other languages. language runtimes
- Sep 26, 2023 How free Recovers a Size From a Bare Pointer The address arithmetic that turns a returned pointer back into its block header, the alignment assumptions that make it work, and the cases where the original base cannot be reconstructed. memory systems
- May 2, 2023 glTF Buffer Views, Accessor Strides, and Matrix Column Padding How buffer views and accessors describe typed views over one binary blob, what the alignment rules forbid, and why matrix columns carry padding bytes. computer graphics
