How good programmers deal with bad codePerhaps your bad line of code has never been written. This is possible, but in reality it is not possible. The reality is that, like all the other programmers on the planet, you'll produce code for security breaches, UI element offsets, and so on. This does not mean that you are a bad developer. Just because you are human--a creature that inevitably makes mistakes.It is this "human" flaw that every developer has that drives good developers to take on the we

What is Cassandra?Apache Cassandra is known for its scalability and fault-tolerant distributed database systems. Cassandra originated from a project that Facebook originally created in Amazon Dynamo and Google BigTable, and has since grown into an open-source system that has been used extensively by companies like Apple and Netflix. The following are some of the key properties of Cassandra:

But when it comes time to do this, we realize that the MicroServices architecture style is a very important idea: something that deserves serious consideration in enterprise applications. We recently used this style to build a few systems that recognize enthusiasts who also use and like this appro

Second, let's talk about the "complete Internet 」.
Adobe repeatedly said that Apple's mobile devices cannot access the "full Internet" because Flash is used for 75% of videos on the Internet. They did not mention that almost all of these videos ar
, the sparsity of the most widely studied movielens dataset is 4.5%, netflix is 1.2%, bibsonomy is 0.35%, and delicious is 0.046%.
From Pearson correlation's calculation formula, if the intersection of two movies is much smaller than that of other movies, the similarity between the two movies is less reliable. From the data sparsity described above, we can see that in the recommendation system, there may be a small number of intersections. This will g

Linux supports 16-bit programs through 32-bit and 64-bit systems. This Is due to Wine (Wine Is Not an Emulator), and most Windows applications can run smoothly. Are you going to enjoy new and old games? The dual system helps you solve the problem.2. HostWhen running the operating system in the native mode (unlike virtual machines),
At the end of last year, Netflix published an article entitled "five lessons learned from turning to Amazon Web Services" (5 lessons we 've ve learned using AWS ). Amazon Web Services (AWS) is undoubtedly an outstanding representative of the so-called "cloud computing. Therefore, this article can also be seen as a key suggestion for any website that wants to switch to the "Cloud. Of course, these suggestions are really great! The following is what sho
With the introduction of several core components from the previous spring cloud, we have been able to build a short (imperfect) microservices architecture. As shown in the following example:We implemented service registries and service registration and discovery using the Eureka in spring cloud Netflix, while service consumption and balanced workloads across the ribbon or feign through the spring cloud Config enables the application of multi-environme
starting with version 1.2.0, Spring Cloud Netflix now supports the use of attributes and Ribbon documentation is compatible from Defining Ribbon Clients . This allows you to change the behavior at startup in different environments.The supported properties are as follows and should be prefixed with:

Performance diagnostics for Linux in 60,000 millisecondsWhen you log on to a Linux server in order to solve a performance problem: What should you check in the first minute?At Netflix, we have a huge EC2 Linux cloud, as well as a number of performance analysis tools to monitor and diagnose its performance. These include Atlas for cloud monitoring, and vectors for on-demand instance analysis. While these tools can help us solve most problems, we still

Why to use ZuulLet's take a look at the diagram below.If we now have four microservices, which are users, orders, payments, and collection microservices, they are invoked using HTTP, restful, thrift, Kafka, respectively. This time if we call the client directly in the sense is not too much effort, the client needs to maintain these methods of invocation of the client, if the late addition of micro-services or reduce or replace the call mode, etc., need to modify the client. So let's see what it'

In a microservices architecture, the service is split into services according to the business, and the service and service can call each other (RPC), which can be invoked with Resttemplate+ribbon and feign in spring cloud. To ensure their high availability, a single service is typically deployed in a cluster. Due to network reasons or their own reasons, the service does not guarantee that 100% is available, if a single service problem, call the service will be a thread blocking, if there is a la
