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

acceleration function, so the CPU has so-called FSB and octave!The so-called FSB refers to the CPU and external components of the speed of data transmission, octave is the CPU used to speed up the performance of a multiple, the two are multiplied is the CPU frequency speed . We have just Intel Core 2 Duo E8400 CPU, his frequency is 3.0GHz, and FSB is 333MHz, so the octave is 9 times times rom!

decomposition (Cholesky decomposition) can be used. Strukturtensor algorithm--Applies to the field of pattern recognition, to find a calculation method for all pixels, to see if the pixel is in the homogeneous region (homogenous regions), to see if it is an edge, or a vertex. Merge lookup Algorithm (Union-find)-given a set of elements, the algorithm is often used to divide these elements into separate, non-overlapping groups.

Any calculation problem can be accomplished by performing a series of operations in a specific order. The problem-solving process (procedure) is called an algorithm (algorithm), which includes:1. Action performed (action)2. Sequence of actions performed (order)The following example shows how important it is to correctly specify the order in which operations are performed:Consider the "Sunrise algorithm" for everyone waking up to work in the Morning: (1) getting Up, (2) undressing, (3) bathing, (

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

I often heard the chief executive say, "If you want to submit a job, data must be good !!』 I believe this sentence involves many people, but is it true? I have been programming for so many years, although I still like data, but I have never used any data in the old saying, I have always been skeptical about the long term. Today, I am going to hear about the structure and presentation of materials in the Information Department.AlgorithmAfter that, I always understand the meaning of this sente

1. Introduction1 What is data compression?Data compression reduces the amount of data sent or stored by partially eliminating the inherent redundancy in the data.Data compression improves the efficiency of data transfer and storage, while protecting the integrity of the database.2 Data compression methodThe data compression method is divided into lossless compression and lossy compression.Lossless compression is suitable for text or programs. lossy compression is suitable for images, video, and

1. IntroductionWhat is a digital system?A digital system (or digital system) defines how a number is represented by a unique symbol.There are two types of digital systems: positional digital systems and non-positional digital systems.2. Position Digital SystemIn a positional digital system, the position that the symbol occupies in a number determines the value it represents.(1) Decimal System① integer② Real numbers(2) binary system① integer② Real numbers(3) Hex system① integer② Real numbers(4) O

method is to apply the principle of the tree file system to a single file system. The tree file system contains subdirectories and subdirectories. Structured Storage stores the data in a file, which greatly improves the efficiency of disk space usage.5. Structured Data First, there is a structure, and then there is data. For example, the data storage method in a relational database does not change the structure of the orders table in the storage pot. The logical structure of the data is determ

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
