Enterprise applications typically sprawl and develop inter-dependencies producing complicated solutions. Ultimately the complexity makes change management complex, error prone, difficult to troubleshoot during service issues and ultimately start impacting the business in multiple ways. To provide the right context when taking up transformation initiatives or addressing service issues one should be equipped with dependency and impact insights. In this video, Rich Lane, a Sr.

Tanay is the Head of Developer Relations at n8n. He has published books on WebVR, virtual assistants on Raspberry Pi, and FirefoxOS. He has been listed in the about:credits of the Firefox web browser for his contributions to the different open source projects of the Mozilla Foundation. I’ve been involved in the DevOps world for a while and yet I finished reading The Phoenix Project only recently. The book piqued my interest in how teams execute their incident response playbooks.

Open-source software started around the millennium and is now one of the cornerstones of modern software development. Open-source projects make their source code available to anyone so that engineers across the world can inspect the code to find bugs or make changes to suit their needs. Today, there are more than 180,000 open-source projects available, according to Wikipedia. We at StackState are big believers in open-source software.

Choosing between blade servers or those intended to go installed in a rack is a small headache that is repeated daily in the complex minds of technicians around the world. What configuration to choose? What can best serve my installation? These are questions that are repeated while they pull out their silvery and silky hairs.

Application performance monitoring (APM) and logging both provide critical insight into your ecosystem. When paired together with context, they can provide vital clues on how to resolve problems with your applications. As the log data you analyze becomes more complex, navigating to the relevant pieces can be tricky using traditional tools. With Elastic Observability (powered by the Elastic Stack), correlating logs with APM is as simple as a few clicks in Kibana.

“If it’s not in Salesforce, it didn’t happen.” You’ve undoubtedly heard it, or perhaps you’ve said it yourself. And why not?

Subscription notification request seen below: Browser notification subscription requests are a legitimate feature that allows visitors of a site to be notified when there is new content available.

At Stackify, we’re all about helping you improve your application’s performance. We have actually developed two code profilers ourselves. Because of that, we like to think we know a thing or two about code profiling. Today I want to talk about the three different types of code profilers, describe the differences between them, and recommend some tools for your toolbox.

In Ubuntu 20.04 LTS, the OpenSSL 1.1.1f library has been modified to use Security Level 2 by default (previous versions of Ubuntu use Security Level 1). Security Level 2 guarantees that protocols, key exchange mechanisms, cipher suites, signature algorithms, certificates and key sizes provide a minimum of 112 bits of message secrecy. In practice, it means that RSA keys are required to be at least 2048 bits long and ECC keys at least 224 bits using the SHA256 certificate signature algorithm.
