SP is incremented and the value is read from $0100+SP. Thestackis said to overflow if theStack Pointeris decremented from a value of $00 to a value of $FF, meaning that the stack has run out of space. Similarly, the stack is said to underflow if the value of SP is incremented from...
The CPU can operate on an aligned word of memory atomically, meaning that no other instruction can interrupt that operation. This is critical to the correct operation of many lock-free data structures and other concurrency paradigms. CPU对于内存中已经对齐了的字的操作,是原子的,也就是说没有其他的...
Stack Overflow has been noted as a successful platform due to its user participation, suggesting that its employment of gamification techniques indeed contributes to its prominence [16]. However, there are questions surrounding the quality of answers on Stack Overflow [25], [64]. In addition, giv...
We used the Stack Overflow question and answer dataset from Kaggle (Kaggle,2022) and BigQuery (Felipe Hoffa,2024). It contains a subset of the questions and tags that are used on the SO website. An annotated SO question (e.g., question title, question body, and tags) is shown in Fig...
That would be the related questions in the sidebar for Question 1234 on Stack Overflow (ID: 1). If we’reonlyin-memory, serialization doesn’t matter and we can just cache any object. However, if we’re sending that cache object somewhere (or getting one back from somewhere), we need ...
