Present perfect or past simple?


Present perfect or past simple? 


Hello my fine fellows!! Today I will go to talk about another thing that not is IT. rsrsrs. We professional of IT needed study English because has various factor that is good for us, in this case, now we will go to talk about when use the present perfect or past simple. OK? Let's go there. 




  1. We use the present perfect when we talk about things that have happened in the past, but we don't say when.
  2. We often use the present perfect with ever( = at any time in your life) and never(= at no time in your life).
  3. We also use the present perfect to talk about something that has recently happened. 


Some examples: 

A - Have you been to Luigis? 
A - Yes, I have

B - Who did you go with? 
B - I went with some people from work

  • We often use the present perfect to ask about or tell somebody about a past action for frist time. We don't ask/say when the action happened: Have you been to Luigis? I've been to New York twice.
  • When use the past simple to ask/talk about the specific past details: When did you go there?
  • When use the pas simple NOT the present perfect with when an past time expressions, e.g yesterday, last week: When did you see it? NOT when have you seen it? -  . I saw  it last week. NOT I've seen it last week.



See you in the next time!

What is JBoss EAP?

Red Hat JBoss Enterprise Application Platform 7, JBoss EAP 7, or simply EAP 7, is an application server that works as a middleware platform, and provides the necessary environment and infrastructure to host and manage Java EE applications. EAP 7 is built on open standards, based on the Wildfly open source software, and provides the following features:
  • It provides a reliable, performant, light-weight and supported infrastructure for deploying applications.
  • It provides a modular structure that allows service enabling, only when required. This improves performance, has security benefits, and reduces start-up and restart times.
  • Web-based management console and management command line interface (CLI) make editing XML configuration files unnecessary, and provide the ability to script and automate tasks.
  • It is Java Enterprise Edition 7 full, and web profile, certified.
  • It provides centralized management of multiple server instances and physical hosts, while a standalone server allows for a single server instance.
  • Pre-configured options for features such as high-availability clustering, messaging, and distributed caching are also provided. JBoss EAP 7 is a cloud-ready application server. It has a very small footprint, fast start-up time, and is automation-friendly. Those features are essential enablers for having an efficient deployment of an application server to a cloud infrastructure. Beyond that, Red Hat provides another offerings for improving EAP 7 cloud deployments: 
  • xPaaS container images for many JBoss middleware products, including EAP 7, as part of the OpenShift Enterprise product
  • Container images for use with Red Hat Enterprise Linux Atomic Host and other Docker-based container hosts, provided by the Red Hat container image registry
  •  Ready to use, supported VM images for Amazon AWS, and other cloud platforms such as Red Hat Enterprise Linux Open Stack Platform and Microsoft Azure deployments to follow
  • Discovery of managed domain server instances deployed as cloud instances

Discovery of clustered server instances deployed as cloud instances or as containers JBoss EAP 7 is part of a growing family of Red Hat JBoss Middleware products, such as:

  • JBoss A-MQ: Multiprotocol, high-performance messaging platform that delivers information reliably, enabling real-time integration
  • JBoss BPM Suite: Business Process Management
  • JBoss BRMS: Business rule management, business resource optimization, and complex event processing (CEP)
  • JBoss Data Grid: In-memory, distributed, NoSQL datastore solution
