First of all, we introduce the new construction site Vqa-lib.github.io.Why do I need to build a site?I think the following two points are useful-Promotion and sharing. Show your research results to the outside world without worrying about levels. High-level research naturally adds luster, and entry-level research can also point the way for newcomers.-Records and inheritance. Everyone stays in the lab for at least two years, and the results of the repo
Experiment 2 network scanning Experiment
Lab Objectives
L use network scanning software to understand the opening of the target host port and service, so as to further obtain information and identify system security vulnerabilities. Capture sensitive data (such as passwords) by using the packet capture software ). Through this experiment, we can learn about the risks of port and service opening, and enhance our awareness of network security protection
Experiment 1 sniffer packet capture
Lab Objectives
L master Serv-U configuration FTP.
L master the basic Telnet usage methods.
L through experiments, master the installation and use of common sniffing tools, and understand the data structure of IP, TCP, UDP, and other protocols in the TCP/IP protocol stack, understand the features of FTP, HTTP, and other protocols for plaintext transmission, establish security awareness, and prevent plaintext leakage
From today on, I will officially write some articles about my graduation design system. I was planning to write some articles before, but I always felt that I was missing some knowledge. After more than two months of accumulation, I gradually formed some ideas. During this period, I completed the development of the debug version of the system, accumulated some experience, and learned a lot. I hope my article will inspire you.
Overture:
More than two months ago, I officially came to my current

The lab uses the ubuntu10.04 Virtual Machine network to configure the lab and the dormitory network. I came to the lab yesterday. To use nfs, you must set up a network to access the Internet using ubuntu10.04 in the virtual machine. Guigong's network has many characteristics. The IP addresses of each machine are almost fixed. In addition, many subnets exist. Ubun
This lab dragged on for a long time to start to finish slowly, spend a lot more, I also didn't expect to need so much time to toss. Consider that it is too long to have all the levels of content sent out at once. So let's do it separately.Then, one thing is, it's really time to get to know gdb before you start solving the problem, because you want to use this tool. Although I also feel that some things can wait for the time to check again, but later f
Do you have some of the qualities necessary to achieve hyper-agile software development? Ravello Systems, a start-up company, explores key guidelines for building a coveted development/testing lab by standardizing the cloud.
In a world where competitive advantage and business agility are almost equal, the reality is that companies often need a lot of time to develop and test software that drives their business.
In software development, hyper-agility
Lab mode consists of three channels, but not the R, G, B channels. One of its channels is brightness, that is, L. The other two are color channels, represented by A and B.
A channel includes a color from dark green (bottom brightness value) to gray (medium brightness value) and then to bright pink (high brightness value); b channel is from bright blue (bottom brightness value)
To the gray (medium brightness) to the yellow (high brightness value). Th
What is Lab color
Lab mode is based on a Commission Internationale de L ' Eclairage (CIE) established in 1931, an international standard for the determination of color, improved in 1976, and named a color pattern and color space. is an alternative color mode other than the RGB and CMYK color modes.
Compared to RGB and CMYK two modes, Lab's function is not available in the other two color modes,
