C++23 introduces new features enumerate and ranges
Optimizing performance for a hot function involves the bulk of the time spent within internal loops. AI suggested using enumerate and ranges, so I consulted some related documentation. The main content of the article was generated by AI, and I tested the code and added some supplementary explanations. Online Compiler – testing C++ code inevitably involves our old friend. On gcc13, traditional for loops were slightly faster than std::views::enumerate, which

“As I recall, Xiaomi was able to break through initially thanks to its solid product quality and distinctive cost-performance advantage – in those early years, other brands would often price similar models at four or five thousand yuan, while Xiaomi could keep the price under two thousand yuan. Many people were switching phones at that time, and they chose Xiaomi because of the ‘low-cost entry into high configuration.’” Current Situation However, in the past two or three generations of flagship phones, the upgrade momentum has noticeably weakened.
Memory timing C36, C30, and C28 – what do these mean? Which one is more suitable at a frequency of 6000MHz?
When assembling or upgrading a computer, we often see memory modules labeled with parameters like “DDR5-6000 CL36” and “DDR5-6000 CL30.” The “6000” represents the memory frequency (MHz), while “CL36” and “CL30” are abbreviations for “CAS Latency,” which is commonly referred to as “timings.”
So, what’s the difference between C36, C30, and C28? How do they affect performance when frequencies are the same? And how should you choose? Let’s discuss this topic in detail today.
Desktop Boot Loader Failure
In July, on a whim, with nothing better to do over the weekend, I decided to clean out the dust from my desktop PC – it hadn’t been cleaned in four or five years, and there was definitely quite a lot of dust accumulated. After cleaning it, I restarted the system, and everything worked perfectly fine. The computer wasn’t turned off regularly; it was left
Breaking Through the Cocoon: Examining Huawei and Xiaomi’s High-End Rivalry Following Xiaomi 17's Renaming
In an era of information explosion, we all, to varying degrees, live within our own “information bubbles.” Algorithms recommend content that interests us, and over time, our horizons are subtly narrowed. This phenomenon seems equally applicable to the smartphone market – brand loyalty, media bias, and community voices are all weaving consumers into one bubble after another.
However, Xiaomi’s recent move, like a stone thrown into a still lake, has created ripples, attempting to break down this invisible barrier.
