1. DNS 1.1 Introduction to DNS Domain name resolution: (English: Domain Name System, abbreviation: DNS) is a service of the Internet. As a distributed database that maps domain names and IP addresses to each other, it can make people access the Internet more conveniently. DNS uses udp53 and tcp53. Currently,the length limit for each level […]

Java obtains video, audio, picture and other metadata information (resolution, size, frame and other information) through javacv
I believe that we all need to return some video or audio information to the front end more or less, so today’s article uses javacv to obtain video, audio, picture and other metadata information (resolution, size, frame, etc.) through Java language 1. First import dependencies You can first import the javacv/javacv-platform dependency. Since the dependency […]
There is a vulnerability in the third-party component used by Android APP. After rectification, an error is reported: ava.lang.NoClassDefFoundError: Failed resolution of: Ljava/awt/Color;
Recently, the company’s app was detected to use third-party components containing vulnerabilities and needs to be rectified. Record: some problems encountered during the rectification process and their solutions. 1. The component commons-net-3.3.jar has a vulnerability CVE-2021-37533. According to the official website announcement, just upgrade to 3.10.0 or above. build.gradle under app implementation ‘commons-net:commons-net:3.10.0’ Apache official […]

Revealing the principle of DNS resolution in docker containers
Background While using docker these days, I encountered some problems with DNS resolution in the container. So I took some time to figure out the principle and wrote this article to share. 1. Container started by docker run command Take starting a busybox container as an example: root@ubuntu20:~# docker run -itd –name u1 busybox 63b59ca8aeac18a09b63aaf4a14dc80895d6de293017d01786cac98cccda62ae […]

AutoX.js – openCV multi-resolution image finding
AutoX.js – openCV multi-resolution image search 1. Cause There are two methods related to finding images in AutoXjs, findImage and matchTemplate. I have never found any problems before. However, when I tested the image search recently, the outlines of the large image and the template image were clear, but I could not find the image. […]
LINGMESS: Linguistically Informed Multi Expert Scorers for Coreference Resolution (lingmess-coref)
