Unicode overflow: It creates a buffer overflow by inserting unicode characters into an input that expects ASCII characters. ASCII and unicode are encoding standards that let computers represent text. Because there are so many more characters available in unicode, many unicode characters are larger than...
// encodeToString() Encodes the specified byte array into a String using the Base64 encoding scheme. // This method first encodes all input bytes into a base64 encoded byte array and then constructs // a new String by using the encoded byte array and the ISO-8859-1 charset. ...

How many users are there? What does the system do? What are the inputs and outputs of the system? How much data do we expect to handle? How many requests per second do we expect? What is the expected read to write ratio?Step 2: Create a high level designOutline...
There's an interesting new C programmer question about malloc: "Given a pointer to dynamically allocated memory, how can I determine how many bytes it points to?" The answer, rather frustratingly, is "you can't." But when you call free on that same pointer, the memory allocator knows how...
The takeaway here is that the meaning of a sequence of bytes depends on the order in which the bytes are interpreted, and that can in turn depend on how many bytes are being interpreted. That particular detail arises from the CPU hardware design. 0 Copy QuinceyMorris answer m...
Many Java collections have a method calledsize(), which returns an integer stating the number of elements in the collection. Arrays have no such method. There are several reasons for this, but the principal one is that arrays are simple Object instances—they are not collections. The Object ...
In MySQL server, if a column name is unique among the tables used in a query, you do not have to use the full qualifier. SELECT with functions. MySQL server has many functions (too many to list here; see Section 6.3). Disk Space Efficiency That is, how small can you make your ...
especially in cloud environments, we often “virtualize” the hardware further so it can be shared across many individual systems in an isolated way. That means there are methods for “hosts” to give access to part of a single CPU or disk to a “guest” operating system that thinks it’...
