| Rule of DesDeMovA | Peter Sommerlad | 03m |
Explains how C++ special member function rules actually behave using Howard Hinnant’s table and why the language sometimes gives copy semantics where you don't… | ||
| Aliasing Redefined | Staffan Tjernstrom | 04m |
Code that type-puns network buffers currently compiles to nothing but invokes undefined behavior; a zero‑code trick is shown that tells the compiler the pun is… | ||
| Why You Should Care about Sparse Matrices | Jeff Trull | 05m |
Dense 4x4 matrices use 16 units of storage and constant‑time indexing, but graphs and nearest‑neighbor meshes scale quadratically while informative entries… | ||

| Undefined Behavior - Not what you expected | Oded Shimon | 03m |
A retry loop decrements an unsigned counter and then immediately dereferences a member pointer that can become null; that null pointer dereference is undefined… | ||
| Choose proper container... automatically? | Alexander Zaitsev | 05m |
An automated tool analyzes collection usage patterns and recommends swapping between vector/list/deque equivalents to improve time or memory behavior, using… | ||
| template＜template...＞ | Kris Jusiak | 05m |
Current C++ lets templates, values and class types be passed in different ways (since 98, 17, 20) but cannot uniformly treat a template name, a raw type like… | ||
