英语好的人是否有像汉语一样一目十行的阅读感 ? 第1页

比较难做到。

鹿鼎记(电子版)俺一晚上就能看完,大唐双龙传(电子版)两天能看完,

但是 The Da Vinci Code 那么薄的一本书俺也要一天才看完。


俺家小孩看英文书也不算很快, 一般也是一个晚上看一本。





在朋友圈里俺也算是 “英语好”的人,甚至俺老婆的导师也这么评价俺。俺就当仁不让冒充一把英语好的人, 蹭些盐值,大家请海涵。

C 环形缓冲的实现: 音频采集后续小实验后续小实验RING/CIRCULAR BUFFER 附送源码

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

俺对 C 一窍不通,看到知乎用户里面程序员人均收入 50 万, 俺也想着培养自己的孩子学编程。但如果父母一点都不懂, 恐怕也难以激发孩子学编程的热情。

俺初中毕业, 没啥文化, 大伙都知道。俺从最开始的 GTK HELLO WORLD 开始, 连滚带爬地,事先开始了自己的征途。这些散文, 就是最近的足迹。




C 音频捕捉的小实验的后续小实验的后续小实验。。。。。。把缓冲区的数据倒到硬盘文件(已完成)。原先存在的问题:BUFFER 的 RAW DATA 通过 BOUBLE BUFFER 再写到硬盘上, 重放没有问题。 RAW DATA 通过端序转换, 存入数组(SIGNED INT 或者 FLOAT), 存入硬盘文件以后。 通过软件重放, 发现存在高频噪音。(已解决)


缓冲区数据转换成 INT 或 FLOAT 或 DOUBLE,端序的问题貌似已经理解。



言归正传

C 环形缓冲的实现: 音频采集后续小实验后续小实验RING/CIRCULAR BUFFER 附送源码


圆形缓冲区(circular buffer),循环缓冲区(cyclic buffer),环形缓冲区(ring buffer),是一种用于表示一个固定尺寸、头尾相连的缓冲区的数据结构,适合缓存实时数据流。


环形缓存放置在20041到20048这8个连续的存储位置。图A示来自输入的8个样本在某一特定瞬间可能被存储的情况,而图B示下一个样本被采集后的变化。


       圆形缓冲区需要4个指针:  在内存中实际开始位置; 在内存中实际结束位置,也可以用缓冲区长度代替; 存储在缓冲区中的有效数据的开始位置(读指针 或数据队列头部指针【计数*标志】); 存储在缓冲区中的有效数据的结尾位置(写指针 或数据队列尾部指针【计数*标志】)。     


环形缓存的技术是这样的,通过重新映射,这个线性数组的终点与它的起点相连。存储位置20041被重新映射成20048的紧邻,就象20044在20045的旁边。通过一个指针来跟踪这个数组,这个指针表示最新的样本落脚的位置。

例如:在图a中,指针包含地址20044,而在图b中,它重定向指向20045。当采集一个新样本时,它总是取代数组中最老的样本,而指针则向前移一个地址。环形缓存的效率很高,因为在获取新样本时只需要改变一个值。管理一个循环缓冲区需要四个参数。

首先,必须有个指针,指示内存中循环缓冲区的起始位置(例如20041)。

第二,必须有一个指示数组结束的指针(例如20048),或者一个存储其数组长度的变量(例如“8”)。

第三,必须指定内存寻址的步长。 例如: 地址20043包含一个样本,地址20044包含下一个样本,以此类推。 但是现实情况可能有变化。例如寻址可能

指的是字节,每个样本可能需要两个或四个字节。在这些情况下,步长大小需要2或4。以上三个值定义了循环缓冲区的大小和配置,在程序运行过程中不会改变。

第四个值,也就是指向最近样本的指针,必须在每次获取新样本时进行修改。

换句话说,必须有逻辑来控制这第四个值根据前三个值的值进行更新。


备注: 卷积不需要循环缓冲,因为每个样本都可以立即被访问。然而,许多算法是分阶段实现的,每个阶段之间都会产生一个中间过渡信号。就象一个递归滤波器作一系列的二象限滤波就以这种方式。当然暴荔法是将每个中间过渡信号的全部存在内存里。环形缓存提供了一种选择:只存储手头计算所需的那些中间样本,可以减少所需的内存,代价是要烧脑重新映射。重要的是,环形缓存对实时应用至关重要,而对离线处理不过是有用罢了。

网上有无数的样板, 但是能用的不多。


例子:

       struct cbuff {   size_t *rtdata;   size_t trunk;   size_t *head_ptr;   size_t *tail_ptr;   bool isfullcb; };  void    init_rqb(struct cbuff *mcb, size_t *mdata, size_t size_power_of_two); int     put_rqb(struct cbuff *mcb, size_t mdata); int     get_rqb(struct cbuff *mcb); int     capof_cqb(struct cbuff *mcb); int     cell_cqb(struct cbuff *mcb);  void init_rqb(struct cbuff *mcb, size_t *rt_stream_ptr, size_t rt_size) {   mcb->rtdata = rt_stream_ptr;   mcb->trunk = rt_size - 1;   mcb->head_ptr = 0;   mcb->tail_ptr = 0; }  int put_rqb(struct cbuff *mcb, size_t mdata) {   if(((mcb->head_ptr - mcb->tail_ptr) & mcb->trunk) == mcb->trunk) {     return 0;   }   DO_SOMETHING(size_t, mcb->rtdata[mcb->head_ptr]) = mdata;   DO_SOMETHING(size_t, mcb->head_ptr) = (mcb->head_ptr + 1) & mcb->trunk;   return 1; }  int get_rqb(struct cbuff *mcb) {   size_t mdata;   if(((mcb->head_ptr - mcb->tail_ptr) & mcb->trunk) > 0) {     mdata = DO_SOMETHING(size_t, mcb->rtdata[mcb->tail_ptr]);     DO_SOMETHING(size_t, mcb->tail_ptr) = (mcb->tail_ptr + 1) & mcb->trunk;     return mdata;   }   else {    return -1;  }     }  int  capof_cqb(struct cbuff *mcb) {  return mcb->trunk + 1;  } int  cell_cqb(struct cbuff *mcb) {  return (mcb->head_ptr - mcb->tail_ptr) & mcb->trunk;}     



俺强行消化了一下, 花了 72 小时。

对于中老年人来说确实是有点费解。

防止有人不看完就血脉贲张,我先把自己的观点凝练总结一下:

尺度适当且全场保持一致,就是好判罚;如果尺度不一致,或者本来尺度一致,最后这下突然不一致,就不是好判罚。所以只有看完了全场比赛才有资格讨论,而不是拿几张截图抠足球规则说事。



皇马1:3尤文的比赛已经过去好多天了,我还是要炒个冷饭。

因为自己是一方球迷,很难在赛后冷静看待,所以赛后不说正事只说情绪。情绪平复了再说正事。

那个点球到底该不该判?

或者说,这是不是个好的判罚?

又或者说,好的判罚的标准是什么?

有人说,标准当然是按照足球规则,该判就判,不该判就不判。

我说——放屁!

只有完全没看过足球比赛的才会说出这种屁话。

真严格按照足球规则来执法比赛,足球比赛就没法看了。

足球规则和判罚真的构成了那一句老生常谈——“严格立法、普遍违法、选择性执法”。

常看足球比赛的都知道,场上球员身体接触根本避免不了——撞人、踢人、推人、拉人,几乎每分钟都在发生。说到底足球是个富有激情的男性运动,男性荷尔蒙里自带侵略属性,你把这些东西完全杜绝了,球员在场上缩手缩脚,不敢做动作,足球运动早被观众唾弃了。

如果裁判完全按照足球规则来吹比赛,一犯规就吹,比赛每分钟都要暂停一下,这叫好的判罚?

好的判罚怎么体现?

两个字——平衡。

坏的判罚怎么体现?

两个字——平衡。

那位说了,好坏都是平衡,你说的才是屁话。姑且说这就是屁话,往下听——

好的平衡是裁判选择一个折衷的判罚尺度。

如果判罚尺度过松,对场上球员的约束小,场面太脏,会变成踢野球,足球运动的技战术之美无法发挥,完全成了身体对抗;如果判罚尺度过紧,就不免要经常吹哨,把球变成死球,严重影响比赛的流畅性,裁判反倒成了主角。

好的判罚就是要在尺度上找一个平衡,裁判在有作为的情况下不抢戏,保证比赛既流畅又不至于动作太脏。

坏的平衡是裁判在两队之间找平衡。

往往这样的裁判心虚,不够自信,又总想显得自己很公平。判罚时不能冷静,判了A队之后又后悔,为了补偿就只好找B队的毛病,判了之后再次后悔,又反过来放松B队严吹A队,导致整场比赛尺度游移不定,但双方在吃牌和危险区域定位球(包括点球)数量上达到了某种平衡。

这种平衡就是坏的平衡。


相比之下,坏的平衡容易操作,好的平衡不容易掌握,所以好裁判难得。

那么什么样的尺度是可以达到好的平衡呢?

答案是:看情况。

好的尺度不是唯一的,而是看双方在这场比赛的具体表现。

如果双方都踢得很文明,尺度就不妨严一点,双方都不会有意见,大家都玩技术不玩身体,那就拼技术呗。

如果双方都踢得很脏,尺度就不妨稍松一点,为了比赛的流畅性,规则什么的就灵活掌握了,守住底线,小动作什么的就算了。

如果一方比较脏一方比较文明,那就要想办法让脏的一方收敛收敛,除了通过判罚之外,裁判与球员的沟通也很重要,让球员明白,我并不是针对你,但我不能放任你这么玩,你们也不想吃牌下去几个吧?


所以正确的操作应该是在开场前30分钟,裁判先要适应双方的风格,然后修正判罚尺度,这30分钟内如果尺度不一致大家也都能理解,毕竟比赛刚开始,双方都有机会,这段时间是球员和裁判博弈的时间,裁判在试探,球员也在试探。慢慢的,双方最终达成一致——这场比赛到底应该是什么尺度。裁判和球员磨合之后产生无声的默契——球员大概知道自己做什么样的动作裁判不会管,什么样的动作裁判会干预;裁判也大概知道球员对什么样的判罚会抗议,对什么样的会默许。尺度一旦达成,就要一直按这个尺度来,双方会一直不断地向裁判施压,为自己一方争利,裁判要做的就是顶住压力,维持尺度。

这才是真正的足球规则!真正的球场跟写在Laws of the Game上的乌托邦是两个世界!


如果裁判尺度不一致,比如全场吹罚都比较松,最后突然紧一下,本来之前都不吹的动作,这时给个点球或红牌,甚至红点套餐,球员不围过来才怪!

因为球员的心理活动是——"I trusted you!" (我白相信你了!)会有一种被欺骗的感觉。比赛都进行了一大半了你突然变个尺度,你玩我呢?


回到皇马1:3尤文那场比赛最后的点球,贝纳蒂亚动作并不大,如果是一个扫堂腿直接撂倒了巴斯克斯,我相信就算是尤文球迷(或者巴萨球迷,嘿嘿),就算这是93分钟,就算尤文几乎创造了奇迹,就算这是布冯最后一次欧冠,谁也说不出什么来,都只会骂贝纳蒂亚,不会骂裁判。但现在这么个动作——说他推人了,似乎也可以说是惯性动作;说他抬脚过高,禁区内解围谁管那么多;说他碰到球了,似乎又是在身体接触后碰到的,到底该不该判?

按照上面说过的标准,我们要看的就是,这个判罚,是否与整场比赛的尺度一致。那么就只有看过全场比赛的人才有评判的先决条件。拿出那几分钟的截图,再把足球规则搬出来,那都是球盲。

没看整场比赛的人首先都闭嘴。

我没看整场比赛,所以我闭嘴。

看过整场比赛的,相信你们心里已经有了答案(虽然是不一样的答案,现在你们有资格继续掐了)。
