Why use it: I’ll typically use a VPN + Proxy configuration if I want my browser IP address to be based in the United States, and my torrent IP address to be different than my browser. So it’s really an extra hop (and IP address layer) for an already secure connection. ’s proxy service is a little different than competitive services, in that in can only be used while you’re connected to their VPN too.

You can easily scale the cache by adding more servers. The underlying infrastructure determines the location of the cached data in the cluster. An application instance simply sends a request to the cache service. Many shared cache services are implemented by using a cluster of servers and use software to distribute the data across the cluster transparently. It locates the cache in a separate location, which is typically hosted as part of a separate service, as shown in Figure 2.Īn important benefit of the shared caching approach is the scalability it provides. Shared caching ensures that different application instances see the same view of cached data. If you use a shared cache, it can help alleviate concerns that data might differ in each cache, which can occur with in-memory caching. Therefore, the same query performed by these instances can return different results, as shown in Figure 1.įigure 1: Using an in-memory cache in different instances of an application. If this data isn't static, it's likely that different application instances hold different versions of the data in their caches. Think of a cache as a snapshot of the original data at some point in the past. If you have multiple instances of an application that uses this model running concurrently, each application instance has its own independent cache holding its own copy of the data. This process will be slower to access than data that's held in memory, but it should still be faster and more reliable than retrieving data across a network. If you need to cache more information than is physically possible in memory, you can write cached data to the local file system. The size of a cache is typically constrained by the amount of memory available on the machine that hosts the process. It can also provide an effective means for storing modest amounts of static data. It's held in the address space of a single process and accessed directly by the code that runs in that process. The most basic type of cache is an in-memory store. Server-side caching is done by the process that provides the business services that are running remotely. Client-side caching is done by the process that provides the user interface for a system, such as a web browser or desktop application. In both cases, caching can be performed client-side and server-side.
Although the CCI exam is optional, we strongly recommend that CCT students take the exam for the CCT designation as this improves your prospects of employment. Next, students will then attend 4-weeks or weekends of classroom instruction for a total of 64 required classroom hours.Īfter passing the course, CCT graduates will have the opportunity to apply and sit for the Cardiovascular Credentialing International (CCI) exam to earn the CCT designation. Make sure to inquire about specific requirements with the department of health in your state. Course Structure:įirst, CCT students will complete 16 hours of online eLearning materials before attending the first day of classroom instruction. Although many employers demand it, certification as a cardiographic technician is optional in some states even though it can help you land a job or demand a higher salary. For the Document/Authorization Title, click on the arrow and select either the Activity Supervisor Clearance Certificate or the Certificate of Clearance.

For the General Application Category, click on the arrow and select Certificate of Clearance/Activity Supervisor Clearance Certificate from the list. One option is to specialize in performing electrocardiography tests on patients. As a Certified Cardiographic Technician (CCT) student, you’ll have hands on training that from current industry professionals that will prepare you to use your CCT skills in real world scenarios. As a certified cardiographic technician (CCT), you work under the supervision of physicians in the diagnosing and treatment of patients suffering from cardiovascular illness. The below test is what I will run to confirm a few things about the resource group, first, that it exists by checking its provisioning state, that it is named how I expect it and lastly that there is only 1. Pester works on the principal of Describe, Context, It, Should and Mock. Pester introduces a professional test framework for Windows PowerShell commands. Let’s take a look below at how this works. Take the ResourceGroup test requirement, this would essentially be: TOPIC Pester tests can execute any command or script that is accessible to a CREATING A PESTER TEST C:PS>New-Fixture deploy Clean Creates two files: It. This includes functions, Cmdlets, Modules and scripts.

I made changes to Advanced hadoop-env and here is my full template As DataNode and NameNode processes run as "hdfs" user normally so please chekc the file permission and ownership.Ĭan you please share the /home/hduser_/datanode.yml file content as well ? If you are able to see the those "javaagent" options in the above process list command output then there may be something wrong in the either the file permissions "/home/hduser/jmx_prometheus_javaagent-0.11.0.jar" and "/home/hduser_/datanode.yml" Or the YAML file content might not be appropriate. In that case please share the full "Advanced hadoop-env" template from ambari UI so that we can check if it was applied properly or not?ī. If you do not see those "javaagent" options in the above commands output then it means that those changes were not applied properly. Hence for making such changes you must use the Ambari UI / APIs, Like "Advanced hadoop-env" from ambari.Īfter you made those changes from Ambari UI do you actually see the mentioned Java arguments when you try to run the following commands? # ps -ef | grep -i NameNodeĪ. In an ambari managed cluster any changes made manually inside the scripts like "hadoop-env.sh" will be reverted back as soon as we restart those components from Ambari UI Because ambari will push the configs which are stored inside the ambari Db for those script templates to that host.

The efficient use of the CPU and the RAM is maximized and more simultaneous requests can be processed than with conventional multi-thread servers. With the standard available asynchronous processing within JavaScript/ TypeScript, highly scalable, server-side solutions can be realized. Fast server-side solutions: Node.js adopts the JavaScript "event-loop" to create non-blocking I/O applications that conveniently serve simultaneous events.The current package managers ( npm or Yarn) for Node.js know more than 1,000,000 of these modules. The basic functionality of Node.js has been mapped with JavaScript since the first version, which can be expanded with a large number of different modules. He developed Node.js out of dissatisfaction with the possibilities that JavaScript offered at the time. Ryan Dahl, the developer of Node.js, released the first stable version on May 27, 2009. This guarantees a very resource-saving architecture, which qualifies Node.js especially for the operation of a web server. Node.js requires the JavaScript runtime environment V8, which was specially developed by Google for the popular Chrome browser. Well-known projects that rely on Node.js include the blogging software Ghost, the project management tool Trello and the operating system WebOS. Made for the web and widely in use: Node.js is a software platform for developing server-side network services.The main reason we have chosen Node.js over PHP is related to the following artifacts: JSON Web Token for access token management.TypeORM as object relational mapping layer.Swagger UI for visualizing and interacting with the API’s resources.Lerna as a tool for multi package and multi repository management. Our whole Node.js backend stack consists of the following tools: Writing and maintaining a Postman collection takes some work, but the resulting documentation site, interactivity and API testing tools are well worth it. These required a lot of effort to customize. We now have #QA around all the APIs in public docs to make sure they are always correctĪlong the way we tried other techniques for documenting APIs like ReadMe.io or Swagger UI. You can automate Postman with “test scripts” and have it periodically run a collection scripts as “monitors”. The result is a great looking web page with all the API calls, docs and sample requests and responses in one place. This turns Postman from a personal #API utility to full-blown public interactive API documentation. You can publish a collection and easily share it with a URL. Then you can add Markdown content to the entire collection, a folder of related methods, and/or every API method to explain how the APIs work. This makes it possible to use Postman for one-off API tasks instead of writing code. This allows you to parameterize things like username, password and workspace_name so a user can fill their own values in before making an API call. You can generalize a collection with “collection variables”. Over time you can build up a set of requests and organize them into a “Postman Collection”. You download the desktop app, and build API requests by URL and payload. Postman is an “API development environment”. For the API reference doc we are using Postman. A public API is only as good as its #documentation. We just launched the Segment Config API (try it out for yourself here) - a set of public REST APIs that enable you to manage your Segment configuration.
