"Memory is a new hard disk, and hard disk is a new tape" is from the Turing prize winner Jim Gray. I. Preface I understand the meaning of this sentence: we should put all random IO in the memory, and leave the sequential Io like the tape to the hard disk (SSD is not included here ). If the application does not reach a certain level, we may think it is too geek to read the above two sentences. However, today

Finally on the UVA see a short topic, happy. After reading the topic, I was ignorant. Then you find the rules ...Find each line represents a letter, and then I start from a a control, write him out. Then a certain pattern was found: the important positions of each line were made up of ' o ' and '-', and a few of them found exactly 7, and then they thought of the Andean Code. Sure enough, the first one represents 2^6, the second represents 2^5, and so on ... If it is ' O ' on behalf of 1*2^X, oth

Programming beauty Reading Notes 15: 4.5 tape file storage Optimization For an arrangement that is already the optimal solution, remember that the length of the I-th file is Bi, and the probability of being accessed is Ai. If you swap the I and I + 1 files, the average length will not decrease. After the swap, When you access the original I files, to access an I + 1 file, the length of the file is increased by AI * Bi + 1, the length of the first

Android microphone custom View with dynamic display of Audio Tape Volume 1. The so-called no picture, no truth, first. What we need to achieve is the button of the middle recording, and the surrounding area will display a waveform of the volume size. 2. VolumCircleBar inherits from View and we have customized it.

tape file storage optimization the algorithm provided in the book 4.5 is a greedy algorithm. The most important thing about greedy algorithms is to prove their correctness. 1. Prove greedy and selective. set X = {x1, x2, X3 ,..., Xn} is an optimal solution. The length of job Xi is L [XI], and the probability of access is P [XI]. set Y = {y1, Y2, Y3 ,..., Yn} is a greedy solution. Where p [Yi]/L [Yi]> = P [Y (I + 1)]/L [Y (I + 1)]. If X and Y a
