通过PREVIEW_TOTLE、ROW_NUMBER参数控制页面的显示【总数表示标签不足时共显示多少格子】 元素少于配置时的总数空格补位和超过时的补位
<?php
define('PREVIEW_TOTLE', 15);//总数
define('ROW_NUMBER', 3);//每行的个数，应可被TOTLE整除
$total = PREVIEW_TOTLE;
$row = ROW_NUMBER;
$count = count($val['tag_ids']);
$last = $total - $count;
$j = 0;

# This Lisp implementation does not provide a s-expression reader.
# Instead, it uses Ruby syntax like following code:

# [:def, :factorial,
# [:lambda, [:n],
# [:if, [:"=", :n, 1],

Latency numbers every programmer should know

CPU

  • L1 cache reference 0.5 ns
  • Branch mispredict 5 ns (on a bad CPU architecture you're pretty much screwed)
  • L2 cache reference 7 ns
  • Mutex lock/unlock 25 ns
  • Main memory reference 100 ns
  • Compress 1K bytes with Zippy 3,000 ns
  • Send 2K bytes over 1 Gbps network 20,000 ns
  • Read 1 MB sequentially from memory 250,000 ns
