What happens when you're out of memory? You may also like: Java Out of Memory Heap Analysis. Recently we experienced an interesting production problem. This application was running on multiple AWS EC2 instances behind Elastic Load Balancer. The application was running on a GNU/Linux OS, Java 8, Tomcat 8 application server. All of a sudden, one of the application instances became unresponsive.

From time and again, I've worked with several Fortune 5000 startups. The most common problem that we've dealt with is microservices testing. While transitioning to a microservices architecture, I've observed teams running into issues where they haven't planned out which testing strategies they want to use. This is especially true for a team that is brand new to microservices.

Blockchains have a uniquely tumultuous early history for an enterprise technology—from a mysterious origin story, to a sensational first application in bitcoin, to a swift fall from a particularly frothy hype cycle. Blockchain technology provides the encrypted distributed ledger that made the first cryptocurrency, bitcoin, possible. Over the last decade, entrepreneurs and intrapreneurs around the world have taken that initial spark and reimagined blockchain by applying the technology broadly acr

Yesterday, I received this question from a distinguished C++ expert who served on the ISO C++ committee for many years. The email poses a decades-old question that still has the classic roll-your-own answer in C++ Core Guidelines #C.130 , and basically asks whether we’ve made significant progress toward automating this pattern in modern C++ compared to what we had back in the 1990s and 2000s.

This car would definitely require synthetic testing. There are two main modes for collecting data about your systems and software: the first is by collecting data from within the application itself, often called white-box monitoring, and the second is by querying the system from the outside and collecting data about the response.

What is AI? In layman terms, AI or Artificial intelligence is the area of computer science that focuses on making machines “intelligent.” And by intelligence, it means making the system capable of learning and taking decisions like humans. Thus, an AI-enabled machine will be able to learn how to react in particular situations and then take decisions in the future according to its learning.

Good luck monitoring an event like this. Monitoring dynamic, distributed environments often results in costly monitoring solution choices for developers seeking scalability, but your monitoring solution doesn’t have to be expensive. Sensu , InfluxDB , and Grafana — open source tools with enterprise counterparts — can work together to create a complete, scalable monitoring solution encompassing event monitoring, data ingestion and dashboarding.

Introduction. Performance spools are lazy spools added by the optimizer to reduce the estimated cost of the inner side of nested loops joins. They come in three varieties: Lazy Table Spool , Lazy Index Spool , and Lazy Row Count Spool. An example plan shape showing a lazy table performance spool is below: The questions I set out to answer in this article are why, how, and when the query optimizer introduces each type of performance spool.

It’s been a while since we last looked at security attacks against connected real-world entities (e.g., industrial machinery , light-bulbs , and cars ). Today’s paper is a good reminder of just how important it is becoming to consider cyber threat models in what are primary physical systems, especially if you happen to be flying on an aeroplane – which I am right now as I write this!

The typical journey for a person browsing a website: view a page, click a link, browser loads new page. That's assuming no funny business like a Single Page App, which still follows that journey, but the browser doesn't load a new page — the client fakes it for the sake of a snappier transition. What if you could load that new page before the person clicks the link so that, when they do, the loading of that next page is much faster?
