【51CTO.com original article】 Activity description : Aiti Tribe is a service community that provides core developers with in-depth technical exchanges, solutions to development needs, and resource sharing. Based on this community, we invite industry technology experts to provide one-on-one breakthroughs on development needs and remove stumbling blocks in the development process. We help developers solve development problems with the most professional and efficient answers. Topic keywords : Machine learning / IDEA / vSphere / cloud computing / SDK tracking / technical management Tribe lineup : 51CTO community think tank Object-oriented : Java engineer, mobile development engineer, IT operation and maintenance, data analyst How to participate : Join the 51CTO developer QQ exchange group (group number 312724475 ). If you have any technical questions, ask them in the group or send them to the group owner. Event Details : Cloud Computing - Enwei - Chengdu : When building machine learning models, how do we judge behavior when encountering emergencies? Network Engineer-sevenot-Chengdu : Machine learning is now divided into three categories: supervised learning, unsupervised learning, and reinforcement learning. Unexpected situations involve unsupervised learning, which means judging abnormalities from learning. Our human brain judges abnormalities based on common sense and experience, but this is difficult to do, which is the difficulty of unsupervised learning. Cloud Computing - Cainiao - Suzhou : Is this statement accurate? Did ESX and ESXi coexist in vSphere before and then ESX was removed, or did ESX get replaced by ESXi after version 5.1? Web-Bai Yang-Zhengzhou : You don't need to understand this. For vSphere, you only need to understand the management of clusters and Vcenter. The rest is the work of engineers. I have taken over vSphere for half a year, and the most used tasks are cluster management and daily operation and maintenance, error reporting and repair. Administrators only need to understand the book written by senior Wang Chunhai. To be honest, unless you are a professional engineer, you don't need to care about the details. If you really want to know more, you can go to the technical manual on the official website, which contains the updated content of each version. 1>Java-Dragonfly-Beijing : Check the "view" menu to see if there is an option to display the directory structure tree. 2>Student-Wang Yang-Wuhan : lower left corner, then click project. Cloud Computing - Cainiao - Suzhou : I suddenly want to ask, from which concepts do cloud computing, cloud platform, cloud services, etc. come? Cloud Computing - Enwei - Chengdu : On August 9, 2006, Google CEO Eric Schmidt first proposed the concept of "Cloud Computing" at the Search Engine Conference (SES San Jose 2006). Google's "Cloud Computing" originated from the "Google 101" project done by Google engineer Christopher Bisciglia. The development of new technologies is based on the concept, and then there are corresponding technical products and services. Although Google proposed the concept of cloud computing, it was AWS that developed the cloud platform, cloud host and services. Android-Yangyang-Beijing : What is the infection method of the Eternal Blue virus? You don't need to do anything? 1> Network Administrator-Thomas-Shanghai : The infection is through the external network port. The external network FW can basically block this attack. The only possibility that can cause the spread is that the users in the LAN bring the virus to the computer. The education network is so widespread because the 445 port is open. The restrictions on corporate networks, especially in terms of egress, are very strict. Unused ports are monitored and blocked. Who would open them completely? 2> Cloud Computing - Enwei - Chengdu : USB flash drives, removable storage, mobile phones can bring in this virus, 445 is just a port, a way of spreading. Never click on unknown links, pictures, emails, software, and various disk resource downloads. Java-Shengxin-Dalian : Today’s headlines, how does it “know” what I want to see? Cloud Computing - Enwei - Chengdu : Create user profiles, attach various labels and attributes, and then push various messages. 51CTO-Xiaoguan : Taking Toutiao as an example, what tools are available on mobile devices to monitor browsing progress? Half-baked full-stack craftsman-Mr. Cao-Beijing : Websites and apps are similar. When it comes to tracking, now they are all post-tracking and full tracking. GrowingIO, Zhuge io and other products are all OK, Umeng is a bit weak. Generally, SDK tracking is implemented, logs are transmitted to the background, such as kafka queues, stored in HBase or HDFS, analyzed and processed through Spark, the results are like ES, and finally visualized through Kibana or Grafana. Android-arige-Beijing : Do you think technology can be a company's moat? Or, can the moat of technology ensure the safety of the company? I feel that the moat dug by technology is just a decoration. 1>PHP-Coeus-Anhui : I don’t think so. Technology is a necessary but not sufficient condition for company security. 2> New Media/Design - Xiaocao - Nanchang : Technology can become a company's moat, but a moat alone cannot guarantee the company's safety. You also need air defense barriers, anti-virus measures, and so on. Xiaoxin-Security-Beijing : What are your experiences in transitioning from pure technical work to management? 1> Dong-Information Security-Shanghai : Recommended route: Technology-Project-Project Management-Management. However, if you do technology in-depth, it is difficult to break away from the fixed technical thinking route. 2> Development - Qi Zixuan - Tianjin : I want to advertise 51CTO. There is a CTO training camp that is dedicated to training people from pure technology to management. However, this is not the most important thing. The most important thing is that you can meet many friends who have moved from pure technology to management positions, and you can exchange a lot of experiences. I feel that the main thing about technology management is the allocation of energy. I usually have 4, 3, 3 (management, technology, product). When you are a manager, you can't always focus on technology. There are many other points that need to be focused on. A place nearby : Does anyone know how to make a USB drive that runs Linux? PHP-Mick-Jiangsu : Download a Linux.iso file and use a USB disk creation tool to make a boot disk. Do you still have questions about these solutions? Welcome to join the 51CTO developer QQ exchange group 312724475 for discussion.
