Preface When we are familiar with how to build our own language service, the rest of the problem is the real completion of scanning and resolution, any excellent language service is indispensable for excellent ScanningProgramAnd the parser. There are many ways to write scanning and parsing programs. I think Lex and YACC are commonly used, otherwise, Microsoft will not implement a C #-based Lex and YACC (I

I. Overviewthis chapter records in the implementation process, creating steps for an AWS EC2 instance. Ii. descriptionAmazon Elastic Compute Cloud (Amazon EC2) provides scalable compute capacity in the Amazon Web Services (AWS) cloud. With Amazon EC2 , you can avoid upfront hardware investment, so you can quickly develop and deploy applications. By using Amazon EC2, you can start as many virtual servers as

Designing highly available applications is an important goal of architects. However, Designing highly available applications based on cloud computing platforms is different from designing traditional platforms. When cloud computing brings many new design challenges to architects, it also brings many new design concepts and available services. How to make full use of the features of the cloud platform when designing applications is an important condition for cloud computing-based design. In this

AWS provides a wide variety of mirrors for users, but in most cases the AMI provided in the community do not fully meet our needs, such as the more disgusting some mirrored root partitions are only 10g, so we generally use the community's public image to create a EC2, And then configure her, and then hit a mirror for the project, Packer can make us more automated to generate AMI, we can write the original image and all the configuration of the content

Most people never need to know what Lex and YACC can do. To compile and download some things, you sometimes need to install them. However, in most cases, it is very easy to use. Some readme files may occasionally mention the "shift/reduce" conflict. In any case, these tools are still a valuable part of the UNIX toolkit and a little understanding of them will be helpful. In fact, although Lex and YACC are al

Learn how to create AWS LAMBDA functions This execute on a scheduled interval and much like a cron job would. In this lesson we'll create a LAMBDA function that checks for a string of text on a website to verify the website are up and operational. The lambda function logs to CloudWatch Metrics and sends a notification e-mail using an SNS queue if the check fails.Create a lambda function: (WebTest)Exports.handler =function(event, context) {varHTTP = re

Most of the frameworks have been set up, and you can use a little extension to be a calculat
