Asp.Net用webrequest获取资源时，报“Theunderlyingconnectionwasclosed:CouldnotestablishtrustrelationshipfortheSSL/TLSsecurechannel.”的错。后面发现我请求的url地址是https的，和普通的http站点不同。解决方案;在请求资源代码前加上如下代码即可：ServicePointManager.

pointer points outside of underlying object

CCS中编译DSP代码时遇到的警告，根据这个警告，我们来排查一下原因，首先看下整个数据结构：出现以上警告的原因就是指针偏移量太多，可能你想使用myDataBuf中的某段数据，但是你的指针偏移到了otherData中了。将偏移中的11改成0~10都可以消除警告，如下图虽然没有报警告，但是代码这样写还是有问题的，因为你将myData的指针指向了myDataBuf[9]此时myData->data[0]

在Python中，字典是通过散列表或说哈希表实现的。字典也被称为关联数组，还称为哈希数组等。也就是说，字典也是一个数组，但数组的索引是键经过哈希函数处理后得到的散列值。哈希函数的目的是使键均匀地分布在数组中，并且可以在内存中以O(1)的时间复杂度进行寻址，从而实现快速查找和修改。哈希表中哈希函数的设计困难在于将数据均匀分布在哈希表中，从而尽量减少哈希碰撞和冲突。由于不同的键可能具有相同的哈希值，即
