So she went out and flash and made some meaningless things to relax herself.There is a tree of n nodes in front of the door, the fragrance found that there are N elves on

"There are only two problems with computer science: Cache invalidation and naming. "--phil KaritonObjectiveNaming has always been a headache in my programming process, sometimes for a proper name is to think and think, but also can not help Google a bit. Naming is really an art, good name that call a tall on. Today, summarize some of the front-end naming conventions, comb one of your own named ideas, and ge

Negative attention refers to classical papers on computer science. There is also a similar statistics on the Internet, that is, citeseer's function "most cited articles ". Just now, I casually looked at it and suddenly found that felle's theory of probability and its application was the top 15, the highest-ranking mathematics book. The original version of this book was published in the 1960 s. The sample

Indicators of the performance of the microprocessor chip include the machine word length-the larger the word, the better the frequency of the machine-the higher the frequency, the better the power consumption-the lower the power consumption the better, the number of transistors-the more transistors the better, the microprocessor can complete the function-the more the type of instruction the better.20. In the tree of computation, the evolutionary th

I recently attended a job fair at big Ivy University (BIU) and talked to about 50 undergraduates majoring in computer science. They hope to go to my company 10gen for an internship or formal job. I'm sure they are smart, but they have not learned how to distinguish themselves from others. In my opinion, these students have similar establishment, similar dress codes, and similar languages to chat with me. I

ArXivThe arXiv (pronounced "archive", as if the "X" were the Greek letter Chi, χ) is a repository of electron IC preprints, known as e-prints, of scientific papers in the fields of mathematics, physics, astronomy, computer, Quantitative biology, statistics, and quantitative finance, which can be accessed online. In many fields of mathematics and physics, almost all scientific papers is self-archived on the arXiv. Begun on August, 1991, arxiv.org passe

What is the difference between an algorithm and a program? The algorithm is a concept, the program is the concrete implementation of the algorithmThe computational thinking pattern means that everything can be seen as a mathematical problem involving numbers and formulas.Two things that any computer can do is calculate and save results.Memory: RamAlu (Arithmetic logic unit): Do some primitive operationControl unit: Track event flowStep: When reading a

This is a paper I have spent a month in my postgraduate studies. It takes only a month to design and write a paper. It can be more than just a few minutes to publish, add, modify, and wait for the paper to be published, I remember writing started in November 2010. I wrote it in December 2010. I made a draft at the end of 2010. I changed it several times in early 2011 and finally published it in May. In November 2010, my tutor said that there were many topics that could be studied on wireless se

cs:app-2.1 Information Store Unknown: knowledge: The word length indicates the nominal size of the pointer data. The most important system parameter determined by the word length is the maximum size of the virtual address space Char types can also be used to store integer values Using an integer type of deterministic size is the best way for programmers to accurately control data representation The pattern of arranging an object byte in a machine for a normal user is a small-ended

The Zen of Python, by Tim PetersBeautiful is better than ugly.Explicit is better than implicit.Simple is better than complex.Complex is better than complicated.Flat is better than nested.Sparse is better than dense.Readability counts.Special cases aren ' t special enough to break the rules.Although practicality beats purity.Errors should never pass silently.Unless explicitly silenced.In the face of ambiguity, refuse the temptation to guess.There should is one--and preferably only one--obvious th

The set of operations that make up a single logical unit of work is called a transaction (transaction).Even if there is a failure, the database system must ensure that the transaction is executed correctly-either the entire transaction is executed or the operation belonging to the transaction is not executed.1. Concept of transactionsTransactions are typically caused by advanced data manipulation languages or programming languages that access written user programs through JDBC or ODBC embedded d
