The Place Where Modern Operations & Technology Come Together
Episode 0: Introducing Request Metrics
Request Metrics is a web performance tool that records how fast your production Page and API endpoints are from your users’ perspective. We are doing something a bit different as we build Request Metrics: all our development sessions are recorded! Follow along as we work our way towards the Version 1 release. We’ll edit out the wrong turns and dead ends, saving you the time we lost along the way.
Episode 1: Creating a new .NET Core 3.1 Project
Development on Request Metrics begins! Before we can write any fun, (hopefully) money making code, we need to get some unexciting ground work out of the way. First on the list: making a new project in Visual Studio 2019.
Episode 2: Building our .NET Core 3.1 Project with TeamCity
The unexciting ground work for Request Metrics continues. We've got a basic ASP.NET Core project up and committed to Github. Now we need to build it! We have used TeamCity to build TrackJS for years. Since we don’t like change, we’re using it for Request Metrics too.
Episode 3: SSH Keys For Server Authentication
In the previous video, we created a build for our new project. Now we are configuring access to the development server using SSH keys. Follow along as we create a new SSH key pair using Git Bash. We'll use PuTTY and the new key to SSH to our Linux server from a Windows machine. Generating a new SSH key is not too difficult, but there are a few gotchas when using Windows. We are going through this exercise because Eric and Jordan develop on Windows. Todd watches in amusement as his MacOS machine "just works".
Episode 3.5: Basic Ansible With SSH Keys
Now that we have a SSH key, we can configure the server to host our ASP.NET Core application. We use Ansible for this because of its relative simplicity vs many of the other available tools. Some extra steps are needed however when running Ansible running in WSL.
On Hermes and Mattermost
With the upgrade to React Native 61 came the prospect of substantially improving performance of our Android app. How? Through the use of Hermes, Facebook’s new JavaScript engine. To say that we were excited is an understatement. And with that excitement came curiosity: How is this new JavaScript engine achieving performance boosts?
HEAL Product Video
HEAL Software Inc. is the provider of game-changing innovation HEAL, the first preventive healing software for IT operations that fixes problems before they happen. Contrary to APM and monitoring tools that send alerts or find the problem sources when an incident occurs, HEAL can recognize "signals" that are leading indicators of future incidents and eliminate factors that can create problems.
Joyful DevOps is Here: Introducing the JFrog DevOps Platform
Unity is strength. And at JFrog, we’re committed to providing the strongest DevOps tools available. With the promised release of the JFrog DevOps Platform, it’s my honor and delight to announce JFrog’s biggest leap yet toward fulfilling our universal vision of Liquid Software. We’re excited and proud to launch the world’s first universal, hybrid, end-to-end DevOps platform.
What are racks and which one should you buy?
A rack is a structure, usually made out of metal and cabinet or wall-shaped, which allows to store and organize the different components of computer installations, such as servers, storage systems, switches, etc. Is that it? Are you disappointed? Well, hold on, although they don’t seem like much, the world of racks can actually be quite tricky.
