整个函数非常棒(来自Linux的sunhme.c驱动程序，用于被Sun戏称为“快乐套餐”的网卡)。因为在那之前的卡片是“巨无霸”。明白了吗?明白了吗?)

static void happy_meal_tcvr_write(struct happy_meal *hp,
                              void __iomem *tregs, int reg,
                              unsigned short value)
{
    int tries = TCVR_WRITE_TRIES;

    ASD(("happy_meal_tcvr_write: reg=0x%02x value=%04x\n", reg, value));

    /* Welcome to Sun Microsystems, can I take your order please? */
    if (!(hp->happy_flags & HFLAG_FENABLE)) {
            happy_meal_bb_write(hp, tregs, reg, value);
            return;
    }

    /* Would you like fries with that? */
    hme_write32(hp, tregs + TCVR_FRAME,
                (FRAME_WRITE | (hp->paddr << 23) |
                 ((reg & 0xff) << 18) | (value & 0xffff)));
    while (!(hme_read32(hp, tregs + TCVR_FRAME) & 0x10000) && --tries)
            udelay(20);

    /* Anything else? */
    if (!tries)
            printk(KERN_ERR "happy meal: Aieee, transceiver MIF write bolixed\n");

    /* Fifty-two cents is your change, have a nice day. */

}

大约10年前，我从事图像处理工作，通过扫描显微镜视频帧来检测细胞运动。我当时在做一个特别复杂的工作，决定和朋友出去喝一杯。当我回到家时，我工作了一会儿，但没有太多，因为我喝醉了。第二天早上，我发现了一个10行完全混乱的函数，带有以下注释(显然是我自己写的):

/* Ah ah ah! You'll never understand why this one works. */

最奇怪的是，它竟然起作用了。

一个奇怪而恰当的有趣错别字:

断言(0);//永远不要在这一点上犯错

// Hard to explain

它最后也坏了。难怪很难解释清楚

 * ...and don't just declare it volatile and think you've solved
 * the problem. You young punks think you know what volatile
 * means... why in my day we had to cast it volatile uphill
 * both ways, and the code still didn't work! Whippersnappers...

有一次，我问一个同事如何用我们的内部框架做一些事情(忘了具体是什么，一些晦涩的技术调用)。 他说“简单，看这里”，然后在他的编辑器中打开一个。java文件，在几页代码中间给我看了这个注释:

// HERE

我刚刚检查了一下，注释仍然在这个文件中:)
