What is Code Profiling? Learn the 3 Types of Code Profilers

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.

Ubuntu 20.04 LTS to enforce stronger TLS v1.2 encryption by default

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.

FIPS certification for Ubuntu 18.04 LTS

Canonical has received FIPS 140-2, Level 1 certification for cryptographic modules in Ubuntu 18.04 LTS, with FIPS-validated OpenSSL-1.1.1. modules included. This certification enables organisations to meet compliance requirements within the public sector, healthcare and finance industries when utilising Ubuntu 18.04 LTS within public and private cloud environments. Canonical worked with U.S. Government and BSI accredited laboratory, atsec information security, for the 18.04 LTS FIPS certification.

How to Run a Time Series Database on Azure

Today we’re pleased to announce the general availability of InfluxDB Enterprise on Microsoft’s Azure Marketplace. We’ll dive into all of these below, but first, let’s take a step back in case you’re not familiar with time series databases. If you’re looking for a time series database, here are three things to look for.

Painting with Data: Choropleth SVG

With the release of the Splunk Enterprise Dashboards Beta version 0.5.2 comes an exciting new feature that I’m sure many people will find useful: Choropleth SVG Objects. What are Choropleth SVG Objects? Put simply, it’s painting with data. To help you navigate getting started with the current iteration of this feature, I’m writing a blog to show you just how easy it is to use and create absolutely custom SVG objects.

Splunk: Going from Monitoring to Observability

In today's complex world of cloud-native applications, with microservices, ephemeral execution and elastic behavior, we need observability. But we already monitor our systems. In fact, observability starts with monitoring. However, observability goes beyond simple monitoring, to give you greater operational insight, leading to shorter incidents, fewer quality problems, a better product, and happier customers.

OpsRamp: Common Operations Problems Solved by OpsRamp Discovery and Monitoring

OpsRamp provides hundreds of out-of-the-box IT infrastructure monitoring templates that capture behavioral and performance metrics for applications, servers, networks, storage, and database instances across hybrid and multi-cloud environments. Combined with powerful AIOps capabilities, modern IT operations teams can leverage both native monitors (pre-built instrumentation for managing IT infrastructure) and custom monitors (user-defined instrumentation for specialized workloads) for proactive IT operations management as a service and responsive troubleshooting.
