without stealing personal information from employees.Redteam Security's Mattgrandy explains that hackers use specific devices when they visit a target company, which costs only $350.Redteam's security advisor, Mattgrandy, said: "(We) have access to large-scale, long-distance readers from the Amazon Marketplace, and they can also be bought from ebay. ” The hacker pretends to be a student visiting the company, placing the device in a laptop bag that intercepts the encrypted communic

hardware, which is used to realize the consistency of successive triangular vertices. In general, advanced Code does not need to know how the vertex cache is implemented and executed.similar to other caching mechanisms, vertex caching is based on the principle that the most recently used data will still be used in the future. The graphics processor caches a fraction of the most recently used vertices, such as 16, and when the API sends vertices, it first detects if the cache already exists. Of

daySecond, the team to estimateThe story point should be estimated by the entire team, the majority of the team will participate in the story of the story point estimation, everyone put their own estimates, and finally everyone agreed to a story pointThird, how to estimate1. All participating customers and developers get together2. Start with the first story and explain the story in detail until everyone knows the story.3, each developer first write down their own estimated value, a story point

the ring are discretized, and finally all the parameters are unified, that is, a two-dimensional meshing algorithm is needed to mesh the two-dimensional parametric space. Finally, the points of the parametric space mesh are mapped back to the geometric surfaces in the polygon, which is the spatial meshing of the surface.Figure 2.1 Mesh UV domain of a SurfaceAs shown in 2.1, the boundary line in the UV parameter space is the Pcurve of the edge of the ring in the topological surface, that is, the

;23541• The LCS with 1,2,3..N is clearly the longest ascending subsequence, with the time descending to O (Nlogn) Promotion: The shortest circuit on the DAG• "Ascent" relies on the order relationship The longest path problem of Dag (a direction-free graph): to consider the biased relationship as a partial order, the algorithm of the subject is still applicable and the time complexity is O (N2). If the graph's number of edges m is compared, it can be further optimized to O (M), because each edge

example, The vertex position of deformed object is deformed only using Targetshape's controlpoints, but the normal deformation is not dealt with at all. I didn't find a way to get effective normals from Targetshape. And when I export the animation as an ASCII fbx, I see that the Targetshape normals data is all 0.My current solution is to get targetshapename by Targetshape and then search the scene by name for the model (mesh) that corresponds to the targetshape, and then get the normal data fro

As a new form of education and modern teaching means, smart classroom brings new opportunities to the education industry.Smart Classroom equipment can reflect the three levels of the Internet of Things

EPC (Electric Product Code) is a standard for the sensing layer of the Internet of things, mainly to define how to define the electronic tag, which includes many rules.The Internet of things is divided into three layers: the perceptual layer, the network layer and the application layer. Perceptual layer is the direct contact layer of objects and objects, like the battlefield of war, such as our bus, IC card and receiver is in the perceptual layer, is the matter and things between each other perc

Introduction to Android NFC development practices + source code SkySeraph Mar. 14th 2014 Email: skyseraph00@163.comABOUT Haha, my first book is about to be published. (It was supposed to be published at the beginning of this year. Like Ma Hang, it was inexplicably dragged on to the present. According to the latest news from the press, it is expected to be officially published in mid-to-late March, so stay tuned). The cover is as follows. Thank you, Mr. Zhang Tao of the people's post and telecom

The first time I heard of RFID, I learned the charm of RFID in the RFID application lab jointly established by the School of transport and NEC at the technical application visit organized by the sophomore school. Previously, I was always curious about the ID bar code of products, and I didn't know the secrets contained in those wide and narrow columns until that

/embedded, the terminal positioning function is initially implemented on the logistics information terminal Platform Based on Embedded Linux and S3C2410.　　Software and Hardware System Design PrinciplesBased on the overall situation of the existing network construction and the requirements for the reliability, continuous coverage and accuracy of positioning data in the logistics distribution process, considering the development status, technical maturity, implementation cost and other factors of

I have previously written an article, irregular graphic UV mapping, (http://blog.csdn.net/itolfn/article/details/17240131) used triangulation algorithm, but the algorithm is not complete, There is one rule: optimality: the diagonal of a convex quadrilateral formed by any two adjacent triangles if interchangeable, the smallest angle in the six inner corners of two triangles does not become larger. is to take four of the maximum triangular angle of the
