research projects. From the perspective of human resources, this is a group organized by students who focus on the promotion of various scientific research projects without dedicated Logistics support teams, such as IT support personnel, provide IT infrastructure support for the implementation of each project; it implementation requires each research project team to promote and manage it by themselves. Therefore, for various research teams of dummi studio, they need to find a service provider t

use of custom scripts and Capistrano. This is a way to work, but it also poses a lot of difficulties. The first attempt at virtualization is manifested in poor performance at peak times of daily visits, where a large number of services are eventually intertwined in the same physical environment, leading to performance anomalies and sometimes downtime due to lack of separation of resources. At peak times, a large-scale deployment of a service consumes multiple threads per request, causing the en

When using the AWS Cloud Service, 90% uses the ELB service as a load-balanced solution, and using Elb is much more convenient than building load balancing yourself. 　　The main benefits of are: 1. Can monitor the health status of the instance at any time; 2. When the server is not normal, the ELB alert policy will automatically send messages to notify the Operators 3. When the server load reaches the threshold, the new server is automatically joine

1. Background In the past few years, social, mobile and cloud computing has profoundly changed the pattern of the entire Internet. As a global leader in the field of software design, Autodesk also formally began to transform from a traditional desktop design software provider to an online service, collaboration and mobile end design in 2009. In this transition, the company took full advantage of the huge advantages of modern cloud computing to bring customers much more than the traditional desk

# Amazon SQS collects and organizes aws sqs documents and uses Ruby demos # Amazon simple Queue Service (SQS) is a scalable and reliable message delivery framework that allows you to easily create, store, and retrieve text messages. You can use it to build Amazon Web Services-based applications. Using SQS is a good way to build loosely coupled web applications. You only need to pay for messages based on your usage. The entire queue framework runs in

networks and overfitting: The following is a "small" Neural Network (which has few parameters and is easy to be unfitted ): It has a low computing cost. The following is a "big" Neural Network (which has many parameters and is easy to overfit ): It has a high computing cost. For the problem of Neural Network overfitting, it can be solved through the regularization (λ) method. References: Machine Learning video can be viewed or downloaded on Coursera
