Today, two weeks ago, I was away from HOL. My colleague called me and said that many users in the Organization reported that their accounts were locked, originally, the account in AD was locked after three wrong inputs. Some users occasionally reported that the account was locked, but the account was locked on a large scale. I think there must be a problem.
When I came back, I looked at the Log, a lot of logs, that is, I guess the password, I suspect there is a hacker attack, and the
According to statistics, the Conficker virus (some variants are reported as Kido) infection has increased, the Forum on the virus to help paste also increased.
It is not obvious that individual users are infected with the worm, and it is relatively easy to clean up, but corporate LANs are not so easy.
The main methods of transmission of Conficker virus are
1. The use of U disk, mobile hard disk automatic
This is an introduction to the face detection of technology from the view of the article:
"2016 ACM MM unitbox:an Advanced Object Detection Network".
The code should not be put out, but the implementation is relatively simple. (Interrupt a sentence, the paper said speed can reach 12fps, I'm a little panic, we look at science does not) —————————— split line —————————— Introduction

The task of image target detection has made great progress in the past three years, and the detection performance has been significantly improved. But in video surveillance, vehicle-assisted driving and other fields, video-based target detection has a wider range of needs. Because of the problems such a

Estimating the distribution of P (x)--Density estimationWe have a sample of M, each sample has n eigenvalues, each of which obeys different Gaussian distributions, and the formula in the assumption that each feature is independent, the effect of the formula is good, regardless of whether each feature is independent. The formula for the multiplication is expressed as shown.Estimating The distribution of P (x) is called the density estimation problem (density estimation)Anomaly

DDoS attacks are essentially time-series data, and the data characteristics of t+1 moments are strongly correlated with T-moments, so it is necessary to use HMM or CRF for detection! --and a sentence of the word segmentation algorithm CRF no difference!Note: Traditional DDoS detection is directly based on the IP data sent traffic to identify, through the hardware firewall. Big data scenarios are done for sl
The Windows Phone operating system can take actions to reduce power consumption on the device when it detects that the user or the current application is in an idle state. depending on the type of application you are creating, you may need to disable idle detection for users or applications. this topic explains how to modify the operating system's idle behavior.
Important Note:
This Windows Phone feature has certification requi

I have roughly translated some of the articles, may have misunderstood the place, please correct me. It is worth mentioning that the debate in the comments section is also worth seeing.
Feature Detection
At first, the front-end engineers objected to browser testing, which they thought was bad because it was not a future-oriented code and could not adapt to new browsers. A better approach is to use feature detec
Example: Cocos2d-x physical engine: collision detection, cocos2d-x Collision DetectionCollision detection is an important purpose of using the physical engine. Using the physical engine can perform precise collision detection, and the execution efficiency is also high.Use the event dispatch mechanism in Cocos2d-x 3.x to manage collision events, and EventListenerP
OpenCV provides four different edge detection operators, or High-pass filters: Sobel,scharr and Laplacian operators and canny operators, the specific detection steps are as follows: image filtering : The algorithm of edge detection is based on first and second derivative of image gray value, but the derivative is usually sensitive to noise, so it is necessary to
In his blog Featuredetectionisnotbrowserdetection of the same name, NCZ describes a popular technology that has been used in front-end development-detection of users' browser platforms, and details historical development and advantages and disadvantages of various methods.

At present, a website has more than one version is very normal, such as the PC version, 3G version, mobile version and so on. Depending on the browsing device we need to be directed to different versions. Not only that, we sometimes need to load different CSS depending on the client, so we need to be able to detect the browsing device so that we need to use the "mobile detection" class library."Mobile Detection
