HOW I USE AN ELGATO STREAM DECK FOR WORK The Elgato Stream Deck is a physical interface designed with numerous buttons that represent various tasks and macros. Installing the Stream Deck software provides a method for configuring the desired tasks and determining what the buttons do and how they appear. Thus, the Stream Deck is both software that let’s me define the things I want DEMYSTIFYING LACP VS STATIC ETHERCHANNEL FOR VSPHERE Both Static and Dynamic (LACP) EtherChannel use the same load distribution methods. I put that in italics and bold to emphasize the point. Yes, it’s true. Static and LACP use the same load balancing techniques to handle traffic. If anyone tells you otherwise, bet against them for an easy way to make some quick cash. This could be

YUBIKEY 5 NFC SECURITY KEY SETUP AND CONFIGURATION To set up a security key, go to Start > Settings > Accounts > Sign-in options, and select Security Key. Select Manage and follow the instructions to setup a new PIN. This will be used when setting up a new account to validate the request. Setting up the YubiKey as a security key with a PIN. BUILDING POWERSHELL ARRAYS AND HASHTABLES FOR JSON While tinkering around with Slack’s Incoming Webhooks feature, I came upon the ability to add message attachments.This seemed like a nifty way to condense a few different pieces of information into a rich formatted Slack message with a bit of PowerShell code. THE SNAZZY SECRET OF POWERSHELL PARAMETER ALIASES The Snazzy Secret of PowerShell Parameter Aliases. PowerShell functions are handy for making portable code that contain all of the requirements and workflow bits baked in, such as the parameters that can be passed over via the user or another script. There’s a lot of choice when it comes to designing the parameters: the type (string,

CONFIGURING THE VMOTION TCP/IP STACK FOR LAYER 3 VMOTION One of the neato-frito features of vSphere 6.0 is the supported ability to use Layer 3 vMotion. It’s even something that Jason Nash and I detailed during our vSphere Distributed Switch 6.0 Deep Dive back at VMworld 2015 US. If you’re interested in setting this up for your environment, I’m going to outline the few steps that are required to do so below. THE EASY METHOD TO EXECUTE SCRIPTS IN NETAPP'S DATA ONTAP The file was then renamed to “ something.txt ” for making volumes, qtrees, etc. and uploaded to the /etc directory. To call the file, use the syntax: source -v /etc/something.txt. The SSH console will then show the commands within the file being executed.

DIY PROJECT: REPLACING THE STOCK HP V1910 FAN WITH GOLDEN Once the screws are out, flip the switch upside down and look for a release slot near the power receptacle. Wedge that open with a screwdriver and the switch enclosure will slide open. Locate the fan; it’s near the power supply.

In a nutshell, multi-cloud design can be achieved with the right ingredients: The conceptual, logical, and physical (specific) model still holds true. Blame Zachman, if you want. 😁. The first investment after prototyping should be a pipeline. HOW TO QUERY GRAPHQL APIS WITH PYTHON In the post called How to Create AWS Lambda Layers for Python, I briefly touch upon the need to retrieve workflow and environment data from GitLab’s GraphQL API.I publish this data to an internal dashboard to track the status of workflows (success, failure, skipped) and the state of environments (available, stopped).The dashboard uses InfluxDB as a data source. USING TERRAFORM TO MANAGE GIT REPOSITORIES Using Terraform to Manage Git Repositories. Storing code and other artifacts into a repository backed by a version control system (VCS) is a fairly well understood and agreed upon technique. However, many organizations I work with are still creating and managing repositories by hand or with one-off scripts. While this method does work, and is USING LAYER VERSION ARNS WITH AWS LAMBDA Using the Layer is painless. In the function’s Designer panel select the “Layers” icon below the function itself. From there, choose Add a layer. Since I already have the ARN, I switched the radio button to Provide a layer version ARN and dropped in the value for requests. Using the Lambda Layer ARN to provide additional module functionality. FILTER TERRAFORM DATA SOURCE BY AWS TAG I could not find a clear description of how to filter a data source by the AWS tag key/value pairs. However, the aws_instance data source provided me a clue..
