This article explains how programs are laid out in memory, the roles of code, data, heap, and stack sections, and compares static linking, which bundles all code into the executable, with dynamic linking, which loads shared libraries at runtime to save disk and memory space.
This article explains the principles of modular programming, examines JavaScript and asm.js module systems, and details how WebAssembly extends these concepts with import/export sections and dynamic linking mechanisms, while also reviewing current proposals and future trends for module linking and component models.
This article explains the principles of modular programming, examines JavaScript and asm.js module systems, details how WebAssembly implements import/export and dynamic linking, and reviews current proposals such as ES Module integration, Module Linking, and Component Model that shape the future of WebAssembly modularity.
This article explains the principles behind Google’s sanitizer tools, especially AddressSanitizer, covering symbol interposition, the interceptor mechanism, and how these techniques replace libc functions to reliably locate memory and thread errors in C++ applications on Linux.
This article clarifies three frequent misunderstandings about iOS15+ dynamic linking—namely the encoding of b/bl instructions, the need for rebase/bind in __TEXT segments, and the mismatch between Mach‑O segment VM size and file size—by explaining the underlying ARM64 architecture, PIC concepts, and providing concrete dyld tool examples.
Fixup chain, introduced in iOS 15, replaces the previous compressed‑byte‑stream rebase/bind format with a linked‑list style structure that stores dynamic‑link information more compactly, improves space locality, reduces binary size, and speeds up app launch by allowing a single pass rebase and bind process.
ELF PLT Hook on Android intercepts shared‑library calls by overwriting GOT/PLT entries, providing a stable production‑ready method for tasks such as APM monitoring, APK unpacking and performance profiling, with a clear workflow, dynamic‑linking background, and a practical implementation using the plthook library.
This article explains the principles of static and dynamic linking on iOS, details how symbol tables, relocation entries, and GOT/PLT work, and demonstrates a practical static‑library hooking technique using relocation tables and the fishhook library.
This article describes a Java‑based solution that dynamically adds brand and model hyperlinks to automotive articles by building multilingual keyword dictionaries with HanLP and employing an Aho‑Corasick Double‑Array Trie for efficient, context‑aware matching without altering the original content.
