addressing hash table, α=n/mThus, if α=50% so expected to explore the number of 2, if α=90%, the expected number of exploration will be significantly increased to 10, so in this strategy, the size of α is very important (Lenovo to the same day birthday problem, also this reason), in engineering some of the hash table using this strategy will force α less than 75%, If this value is exceeded, the hash table is automatically expanded.The expected number of search 1/(1-α) is how to calculate, as fo

Moving DL we have six months of time, accumulated a certain experience, experiments, also DL has some of their own ideas and understanding. Have wanted to expand and deepen the DL related aspects of some knowledge.Then saw an MIT press related to the publication DL book http://www.iro.umontreal.ca/~bengioy/dlbook/, so you have to read this book and then make some notes to save some knowledge of the idea. This series of blog will be note-type, what is

Release date:Updated on: Affected Systems:MIT Kerberos 5 1.11Description:--------------------------------------------------------------------------------Bugtraq id: 63832CVE (CAN) ID: CVE-2013-1417 Kerberos is a widely used super-powerful encryption to verify the network protocol between the client and the server. In KDC versions earlier than Kerberos 5 1.11.4, do_tgs_req.c has a remote denial of service vulnerability caused by NULL pointer reference when using a single-component domain name,

Fibonacci sequence Fibonacci Sequence, also known as the Golden section of the series, refers to such a series: 0, 1, 1, 2, 3, 5, 8, 13, 、...... Mathematically, the Fibonacci sequence is defined as a recursive method: F (0) =0,f (1) =1,f (n) =f (n-1) +f (n-2) (n≥2,n∈n*)There are a pair of one-month-old male and female rabbits, in another one months when mating rabbits, assuming they are born of two a male and female rabbit, at the end of the next month these two rabbits also have offspring is al

the caller's stack frame. Where our function is to get the value of the current stack frame EBP register, and the return address in the caller's stack frame, the input parameters passed to the current stack frame.So, according to the distribution of the data in the graph, we can know that the value of the register EBP is the highest address of the current stack frame, and that the memory unit that corresponds to the highest address is exactly the highest address of the caller's stack frame.The

mapping of the delivery page, in which the receiver and the sender are mapped to the same physical page at the same time, and memory sharing is realized. These two functions are then implemented in the same system call First look at the SYS_IPC_RECV function in the kernel. When a process tries to receive information, it should mark itself as receiving information, and in order not to waste CPU resources, it should also mark itself as env_not_runnable, and only if a process has sent the message

I decided to take a few big parts. Today, I started to study in open classes. One is to consolidate my understanding of algorithms, and the other is to share my learning experience. The algorithm class at Princeton University seems to have been completed. There are only handouts, and there seems to be no video. Next I will take an introduction to algorithms at MIT. 　　I am a lazy child. I hope you can supervise me. No supervision, I can't continue, er,
