clojureDesigning Hyper-V Dynamic Memory: Requirements, Boundaries, and Operational Checks
Learn how to size Hyper‑V Dynamic Memory, verify balloon driver operation, and avoid guest‑OS thrashing while maximizing VM density.
Managing Memory and Performance with Haskell's Lazy Evaluation
Learn how to balance Haskell's lazy evaluation with strictness annotations to prevent space leaks and implement efficient infinite data structures.
haskellHow We Fit 16 MB of RAM Into 640 KB: The MS-DOS Memory Maze
MS-DOS's 640 KB barrier forced three incompatible memory schemes—EMS, XMS, and HMA/UMBs. This blog walks through a real DOS 6.22 optimization, showing how driver order and switch choices reclaim conventional memory for DPMI apps like Doom.
msdosChoosing Nim's Memory Management: Boehm GC, ARC, or Manual Mode
Learn how to pick Nim's garbage‑collection model—Boehm GC, ARC, or manual—based on latency, determinism, and C interop, with a concrete ARC file‑closure example.
Asynchronous Asset Loading with LibGDX AssetManager: Patterns and Pitfalls
Learn how to load textures, sounds, and data asynchronously with LibGDX AssetManager, avoid render‑thread stalls, and dispose native resources safely. Includes a complete loading‑screen example and a verification checklist.
How MS-DOS Engineers Cracked the 640 KB Barrier: HIMEM.SYS, EMM386.EXE, and the Art of Loading High
A practical walkthrough of how MS-DOS 6.22 used HIMEM.SYS and EMM386.EXE to break the 640 KB barrier — covering the HMA, UMBs, EMS vs XMS, a real CONFIG.SYS example, and the compatibility trade-offs that still matter for legacy systems.
Choosing Owned, Unowned, or Weak References in Vala to Manage GObject Lifetimes
A decision guide for Vala developers on when to use owned, unowned, or weak references to manage GObject lifetimes, with a concrete parent‑child cycle example and validation steps using valac, Valgrind, and G_DEBUG.
valaAvoiding Data Corruption in Fiber: The Danger of Pooled Contexts
Fiber's high performance relies on pooled contexts to minimize GC overhead. Learn why this 'Zero-Allocation' approach can lead to data corruption in goroutines and how to fix it.
