clear rules and clear positions, or a combination of open options. Stock selection methods and weights are clearly determined. Exponential investment is full. It determines the three essential aspects of a portfolio, including the configuration of major asset categories, stock configurations, that is, positions, stock types, and individual stock weights. Or in the future, there will actually be similar foreign products that control stock positions based on a certain indicator.Investment with cl

MySQL 5.7 JSON support Recently, a business needs to store Json and perform some simple business logic processing. I have found that it is difficult to use mysql 5.6 for json data analysis. It is very difficult to simply store data. I have no way to ask.I first thought of mongodb, and second thought of mysql 5.7. Then, check it out. Oh, it's GA. As we all know, mongodb's engine layer stability has been a short board, while innodb has been very stable after 10 years of verification. So I was wond

Be alert for attacks with CVE-2015-2545 VulnerabilitiesPreface Recently, APT Warning Platform captured an attack sample, after analysis, the sample seems to use CVE-2015-2545 for attacks, and has a high level of attacks.Analysis This sample is constructed by a User-After-Free vulnerability in the Encapsulated PostScript (EPS) filter module (EPSIMP32.FLT in 32bit. The causes and utilization of vulnerabilities are as follows:When processing the copy op

For some developers, I feel that this is important at 01:10. WY started to learn programming in the second day. Think about yourself. I have never touched on programming languages in the second day. ① Alignment related ② Indent ③ The curly braces behind if are written in another line. ④ Variable alignment ⑤ Blank lines: Role of separati

PhotoCD images are mostly of very high quality. 13 DXF (. dxf) The Drawing Interchange Format (Drawing eX change Format) is a graphic file format in AutoCAD that stores graphics in ASCII form and is accurate in terms of the size of the graphics Can be edited by large software calls such as CorelDRAW and 3DS. 14 Ufo It is a dedicated image format for the wel

Given n three-dimensional plane points, each point has a height. The edges must be constructed between each two points. The edges are determined by the Euclidean distance of the X and Y coordinates, the cost of edge is determined by the Z value. How much is the minimum cost ratio in a reasonable spanning tree? Solution: each edge corresponds to a height difference. If the height difference of each edge is set to hi and the distance is Li, a set of edge sets must be found. As always, let's assu
