Getting PowerShell on Linux

Well it’s not just an announcement, you can actually get PowerShell on Linux and MacOS right now from GitHub – here!

Installing PowerShell

Once you’ve downloaded an installation file you can use RPM or apt to install the package. If you’re on a Mac…well just double click on the package!

yum install powershell-6.0.0_alpha.9-1.el7.centos.x86_64.rpm

If you’re on Ubuntu, you’ll need a little more stuff read <a href="https://github.com/PowerShell/PowerShell/blob/master/docs/installation/linux.md#ubuntu-1404">this</a>.

Running PowerShell

We’ll there’s really not much to that, just type **powershell** at the command prompt an you’re off and running!

Paradigm Shift!

What do I mean by that? Every once in a while a technology comes along and changes the way things are done, moves the bar…well last week Microsoft released a Channel 9 video on persistent memory using NVDIMMs and DAX on Windows 2016…then combining it with SQL Server! This is one of those technologies that moves the bar! Check it out here.

Why is this important?

Relational databases like SQL Server use a transaction log to ensure the durability of the transactional operations to the database. This is so it can ensure its data is consistent in the event of a system failure. SQL Server uses a logging protocol called write ahead logging (WAL). This means that the data change operations must be written to stable, persistent storage before the process can change data in the database file…so this means our database throughput is at the mercy of the performance of the device the changes (log records) are written to.

My new course “LFCE: Advanced Linux Networking” in now available on Pluralsight here!

This course targets IT professionals that design and maintain RHEL based enterprises. It aligns with the Linux Foundation Certified System Administrator (LFCS) and Linux Foundation Certified Engineer (LFCE) and also Redhat’s RHCSA and RHCE certifications The course can be used by both the IT pro learning new skills and the senior system administrator preparing for the certification exam

I’m proud to announce that I will be speaking at IT/Dev Connections on October 11th 2016 in Las Vegas! I can’t begin to tell you how excited I am to be able to speak at this conference! I look forward to seeing you there!

Here’s the information on the talk!

Designing High Availability Database Systems using AlwaysOn Availability Groups

**Track: **Development Platform Tools and Devops

Abstract:

Are you looking for a high availability solution for your business critical application? You’re heard about AlwaysOn Availability Groups and they seem like a good solution, but you don’t know where to start. It all starts with a solid design. In this session we introduce the core concepts needed to design a Availability Group based system. Covering topics such as recovery objectives, replica placement, failover requirements, synchronization models, quorum, backup and recovery and monitoring. This session is modeled after real world client engagements conducted by Centino Systems that have lead to many successful Availability Groups based systems supporting tier 1 business critical applications.

I’m proud to announce that I will be speaking at SQL Saturday Baton Rouge on August 6th 2016! This will be my forth SQLSaturday event this year and I’m really excited that I get to do it as a speaker. I look forward to seeing you there!

If you don’t know what SQL Saturday is, it’s a whole day of free SQL Server training available to you at no cost!

I’m proud to announce that I will be speaking at SQL Saturday Sacramento on July 23th 2016! This will be my third SQLSaturday event this year and I’m really excited that I get to do it as a speaker. I look forward to seeing you there!

If you don’t know what SQL Saturday is, it’s a whole day of free SQL Server training available to you at no cost!

If you haven’t been to a SQL Saturday, what are you waiting for! Sign up now!

The developments over the last few months in the data community had brought us to an interesting place. We’re going to have SQL on Linux and now we also have .NET on Linux too! While the implications of this are unclear, and worthy of significant prognostication…I’m going to take this time to show you how to get started with.NET Core on a Redhat Enterprise Linux Based System.

First up you’re going to need Redhat Enterprise Linux. The Redhat Developer Suite, now includes a free license of RHEL go get it on Redhat’s site.

I’m pleased to announce that I’m working on a new course for Pluralsight.

The course is titled LFCE: Advanced Linux Networking.

This course targets IT professionals that design and maintain Linux based enterprises. It aligns with the Linux Foundation Certified Engineer (LFCE) objectives and can be used by both the IT pro learning new skills and the senior system administrator preparing for the certification exam. This course will dive deeper into the internals of networking, giving the viewer insight into how things work under the hood in Linux based networks.

In this post we’re going to introduce the basics of CPU scheduling.

In a computer system, only one thing can happen at a time. More specifically, only one task can be on a processor at a point in time. This can expand to several tasks if the system has multiple processors or a processor with multiple cores, which most modern systems have. For example, a four core system can potentially execute four tasks concurrently.

My new course “Understanding and Using Essential Tools in Enterprise Linux 7” in now available on Pluralsight here!

This course targets IT professionals that design and maintain RHEL based enterprises. It aligns with RHCSA and RHCE objectives and can be used by both the IT pro learning new skills and the senior system administrator preparing for the certification exam

Let’s take your LINUX sysadmin skills to the next level and get you started on your RHCSA/RHCE learning path.
