Internet Explorer, Safari, Firefox, Chrome, Opera ...... The war between Web browsers seems to have never been so intense. Microsoft, apple, Mozilla, Google, and Opera Software boast of their own products. Which of the following is the best?
After standards have been set up in the graphics card, machine, automobile and other fields, Futuremark today released a free browser benchmark performance testing tool "Peacemaker", which is peace guard, to ease
Width: 100% what is the benchmark test, width reference
At first, we encountered the following problem: when the box model is set to box-sizing: border-box; (this is often done on mobile terminals ). The sub-box width: 100%. Is the sub-box width equal to the contend length of the parent box or the condend + padding + border length?
Css and html:
Result:
(Width of second) = (length of contend of first)
Next, we will summarize the referen

2. ntimes: adjusts the number of stream operations in each kernel and outputs the best one. Set 7 times.
It can be adjusted through-dntimes = 7.

Futuremark has released the Windows 8/RT version of 3DMark performance test software and has allowed users to score comparisons with other platforms, such as Android or iOS. Application of the test project is still ice Storm, ice Storm Extreme and ice Storm unlimited three species. The Ice storm test is a test project designed for mobile devices that supports the 720p fixed-resolution DirectX 11 benchmark and is then output to match the native display

Recently, in a colleague's question: when iterating over a slice, it would be better to move the loop condition out of the loop for len than the Golang compiler's optimization results.
That
func G0(a []int) int { L := Len(a) for I := 0; I L; I++ { } return 1}
Whether it will be better than
