Generally, the performance and timing problems of dns are caused by suspicious query results. In this case, no matter whether the dns is parsed or not, the consequences are the same. What should we do for actual problems such as long response time, timeout errors, and invalid cache? After all, these types of query responses are still possible to pass. It only requires more time. In fact, in this case, the waste of bandwidth is the real key issue. Now let's assume another situation: we must use a

I. Overview of Benckmark testing on Android devicesPerformance testing on Android devices does not yet have a recognized standard compared to PCs. There are not so many test assemblies on the PC. But we can get a better understanding of the features of the device through the information obtained by some tools, and there is no doubt that this is valuable reference information. The key to Benchmark test is how to find this standard and the powerful asse

Title: Given y, the maximum value of K ((y-1960)/10+2) > k! is satisfied.Problem-solving ideas: Through the two sides at the same time to the logarithm, to achieve the effect of power, so that the number of both sides can be stored with their own type.After taking the logarithm: 2 ((y-1960)/10+2) * Log (2) > Log (k!).Further conversions: 2 ((y-1960)/10+2) > log (k!)/log (2) = log (k)/log (2) + log (k-1)/log (2) + log (k-2)/log (2) + ... +log (1)/log (2).Due to Y The final traverse to solve K can
